Beto ORourke Biography

Beto O'Rourke Biography Beto O’Rourke (born Robert Francis O’Rourke on Sept. 26, 1972) is a Texas politician whose progressive politics, enthusiastic following on the campaign trail, and aspirations to the presidency have earned him comparisons to a  Kennedy  and  a young Obama. O’Rourke is a former businessman who served three terms in the  U.S. House of Representatives  before embarking on what would be the most expensive, yet unsuccessful, campaign for  U.S. Senate  in the midterm elections of  President Donald Trump’s first term. Fast Facts: Beto O'Rourke Full Name: Robert Francis O’RourkeKnown For:  American politician and potential presidential hopeful. His unsuccessful campaign against Republican U.S. Sen. Ted Cruz was the most expensive in the 2018 congressional midterm elections, costing $80 million.Born:  Sept. 26, 1972, in El Paso, TexasParents:  Pat and Melissa O’RourkeSpouse:  Amy Hoover SandersChildren:  Ulysses, Henry and MollyEducation:  Columbia University, bachelor of arts degree in English literature,  1995.Famous Quote:  I can think of nothing more American than to peacefully stand up, or take a knee, for your rights, any time, anywhere, in any place.Fun Fact:  ORourke played bass in a punk band called Foss. Early Years  and an Unusual  Nickname for an Irish Kid O’Rourke was born in El Paso, Texas, the son of Pat and Melissa O’Rourke. His father was in politics, serving as a Democratic county commissioner and judge before switching  parties and mounting an unsuccessful campaign for Congress. His mother worked in a furniture store. O’Rourke’s family had immigrated from Ireland four generations before, but the young man went by Beto- short for Roberto in Mexico. â€Å"My parents have called me Beto from day one, and it’s just- it’s kind of a nickname for Robert in El Paso. It just stuck,† he has said. As a young man, ORourke often accompanied his politician father around town. He told an interviewer in 2018 that he and his father were far apart in their enjoyment of glad-handing and schmoozing.  Ã¢â‚¬Å"He had this real joy in public life, in meeting people and representing people,† the younger O’Rourke recalled about his father. In some ways, I really hated it.  It was the kind of stuff you don’t want to do when you are 10 years old, unless you were really into that. And I wasn’t. I was an awkward and shy kid, so it was the last thing I wanted to do, but now I can look back and bless my experience in it.† As a young teen in high school, ORourke sought distance from his father by transferring from the public high school in El Paso to an all-male boarding school in Virginia, Woodberry Forest. After graduation he entered Columbia University in New York, where he majored in English literature, worked at a publishing house, and wrote fiction while playing bass with a punk band with some friends. After graduating from college, ORourke moved back to El Paso in 1998, and co-founded a software and technology company called Stanton Street Technology Group. He also became a partner in a real-estate firm and invested in property in his home town. Political Career ORourke was catapulted to political fame with his folksy 2018 bid for U.S. Senate against  Republican incumbent Ted Cruz- he livestreamed a 254-county tour of Texas- and his accessibility in the House. He was popular with small-money donors and progressive activists, much the way  Bernie Sanders  was in running for president in 2016. But his political career began on a much smaller level, as a member of El Paso city council from 2005 to 2011. It was during his tenure on city council that he became involved in a controversy that placed him squarely between the interests of his wealthy investor father-in-law and the angry residents and small businesses he was elected to represent. ORourke sided with his father-in-law and publicly supported the plan to replace  tenements and boarded-up buildings in  downtown El Paso with restaurants, shops and an arts walk, a move that angered his constituents. His first step into the national political spotlight came in the May 2012 Democratic congressional primary in Texas, when ORourke knocked off an eight-term incumbent who had been endorsed by  President Barack Obama  and  former President Bill Clinton,  U.S. Rep.  Silvestre Reyes. ORourke was elected that year to represent the 16th Congressional District in El Paso. ORourke served three two-year terms in Congress, and had several pieces of legislation signed into law. One was the â€Å"Honor Our Commitment Act,† which expanded mental health care to veterans with â€Å"other-than-honorable† discharges from the military.   He did not seek re-election to the House in 2018 and chose instead to challenge Cruz for one of the states seats in the U.S. Senate. Cruz narrowly won the race, which in an of itself was shocking because Texas is overwhelmingly Republican. ORourke, though defeated, had accomplished much by running so close to an entrenched incumbent. ORourke has said he is weighing a run for president in 2020. Personal Life and Wealth ORourke married his wife, Amy, in 2005.  She is  the daughter of wealthy real estate mogul  William â€Å"Bill† Sanders. The ORourkes have three children: Ulysses, Molly and Henry.   The Center for Responsive Politics estimated Beto O’Rourke’s net worth as $9.1 million in 2016. His net worth and familial ties to a wealthy real estate investor made him an unlikely star among young progressives in 2018. Arrests O’Rourke has been relatively open about facing criminal charges- one for drunk driving and another for breaking into a facility at the University of Texas at El Paso. Both cases have been used against him by political opponents. In the drunk-driving case, from September 1998, O’Rourke was allegedly driving at a high rate of speed when he crashed his car about a mile from the Texas border with New Mexico. A breath-test administered by police found O’Rourke’s blood-alcohol level was above the legal threshold, 0.10 percent. The 26-year-old’s reading was a high of 0.136, according to published reports. The charge was later dismissed after O’Rourke completed a court-approved program. He has described the DUI as a â€Å"serious mistake for which there is no excuse.† Three years earlier, in 1995, O’Rourke had been charged with attempted forcible entry to the physical plant at the University of Texas at El Paso, where he was a student. He spent a night in the El Paso County Jail, made bail the next day and was released. The charge was later dropped. I along with some friends were horsing around, and we snuck under the fence at the UTEP physical plant and set off an alarm. We were arrested by UTEP police. ... UTEP decided not to press charges. We werent intending to do any harm, he has been quoted saying. Sources and Further Reading Saul, Stephanie. â€Å"Beto ORourke Once Supported an El Paso Real Estate Deal.

How the Spotted Owl impacted small communities. Conservation vs. Preservation.

How the Spotted Owl impacted small communities. Conservation vs. Preservation. Conservation and preservation are terms that are used frequently in the 21st century. With earths natural resource's dwindling, many laws have been put into effect regarding the conservation and preservation of certain ecosystems. The purpose this paper is to compare and contrast both conservation and preservation. In this paper I will also explain the concept of natural regulation, and how the term relates to the importance of a protected ecosystem.I was 10 years old the first time I learned the meaning of conservation and preservation, especially how they impact a local ecosystem like my own community. My father worked as a logger in the small town of Lyons, Oregon. He had been a logger for most of his adult life, while my mother was a school bus driver. The majority of household income for Lyon's and neighboring Mill City is earned from the lumber industry. In the late 1980s the Oregon spotted owl became a hot topic for American news stations.Northern Spotted Owl (Strix occidental is caurina) ...Environmental groups had begun filing petitions seeking protection for owl which claimed the bird was in jeopardy of extinction. The reason behind this is that the spotted owl lives in old growth trees located throughout the Pacific Northwest.Logging and clear-cutting the old growth forests result in a destroyed ecosystem that these owls live in. I can recall the small community being outraged by such reports since many jobs could be lost if logging theses forests was banned. Environmentalists argued the only way to protect the owls is by preserving the old growth forests and to cease all logging in these areas. Local people took conservative approach by claiming that the logging and owls could co-exist with proper land management. The preservation theory won approval in the courts which lead to the owl being added to the list...

Music Jongleur Essay Example | Topics and Well Written Essays - 500 words

Music Jongleur - Essay Example During the 9th century, the song â€Å"Veni creator spiritus† has been utilised in various kinds of religious observances. Apart from the Religious observances which commonly haunted the music in medieval periods, there also exists some place for the love songs which dominated spiritual music. The composer has composed the love songs in his native language where he lived (usually in Old Occitan or Latin or Old French).One of the best example of love song is â€Å"Sic Mea Fata† which was written in latin and was seen in a manuscript from the abbey of St.Martial in Limoges. Jongleurs usually perform their work along with some dance. One of them is ‘estampie’. The above mentioned form consists of two successive melodies which was given a name as ‘puncta’ of which the first part ends with an unclosed ending and the second part ends with a concluded ending. Therefore ‘La Uitime Estampie Real’ meaning ‘The Eighth Royal Estampieâ₠¬â„¢ was one among those French dances which was performed by the Jongleurs in the early period. ‘Souvent Souspire’ is also one of the famous French dance song performed by Jongleurs. Also earlier Jongleurs commonly came across ‘hurdy-gurdy’ type of music supplemented with dance.

Mergers And Acquisitions Essay Example | Topics and Well Written Essays - 2750 words

Mergers And Acquisitions - Essay Example Usually, mergers and acquisitions are primarily driven by the objectives of growth and survival. A large company will seek to acquire a smaller company for the purposes of benefitting from certain synergies in various aspects of the business operation. This may include an expanded market segmentation or technological development. Companies with nearly the same market profile may merge to enhance the level of efficiencies of operation and minimize on operational costs. On the other hand, smaller companies may be willing to be acquired by bigger firms due to a hostile market environment or unpalatable market forces (Sherman, 2012, p. 67). In essence, mergers and acquisitions are aspects of business strategy. In business, there exists the possibility of a mismatch between strategy and reality. Errors of judgment by directors may lead to ill-conceived mergers and acquisitions particularly resulting from the effect of misguided information or the flux nature of the global market forces. I t might be important to analyze the rising cases of failure from this perspective. Why Directors Prefer Mergers and Acquisitions Despite the recorded failures, corporate directors have continued to pursue mergers and acquisitions with remarkable determination. Usually, the pursuit of these goals is strategic in the sense that they aim at achieving a certain goal in the business operation. The synergistic benefits of engaging in mergers may tend to surpass the possible risks involved (Moeller & Brady, 2011). Directors often decide on mergers basing on certain strategic goals. Decisions are taken after cost-benefit analyses are conducted with regard to the possible risks involved in the purchase. A merger or an acquisition may present the most appropriate alternative to the growth and expansion alternatives available for the company (Sun, 2012). For instance, a company may want to expand its technological infrastructure within a specified period of time. Some of the factors to be cons idered include times, cost, and reliability of the development. The firm may choose to enlist the services of experts to carry out this particular development. Alternatively, the firm may choose to enter into a merger or engage in an acquisition with a firm that is already established in terms of technology with a sound technological infrastructure (Buckley & Ghauri, 2002, p. 22). This move would have saved the firm a substantial amount of money, which would be directed to alternative areas of development. Another reason why boards of directors still engage in mergers and acquisitions is to be seen in terms of expansion strategies. Market discourses of globalization and liberalization have brought about stiff competition in most areas of business operations. Mergers and acquisitions provide the most effective way for a company to consolidate its hold on a certain market segment with the short-term and long-term objective of locking out external competition (Lucks, 2007). When two la rge corporations enter into a merger, they are most likely to expand their market reach and intimidate other firms that may seek to operate in their business niche.  

Procedure For Analysis And Simulation Using Ansys

Procedure For Analysis And Simulation Using Ansys This section describes the overall workflow involved when performing dynamic transient structural analysis in the Mechanical application by using ANSYS Workbench 12.0. Each step will include with figure that show how the analysis and the result been prepared. 5.2 Create Analysis System There are several types of analyses you can perform in the ANSYS Mechanical application. However, in this chapter only Transient Structural Analysis procedure will be cover to determine the dynamic response of a structure under the action of any general time-dependent loads. The following steps explain how to build a system in ANSYS Workbench. The appropriate group in the Toolbox has been selected with the Analysis Systems group. The appropriate template has been selected which is Transient Structural (ANSYS). The template in the Toolbox has been double-click, or drag it onto the Project Schematic. All possible drop locations has been preview by using a drag-and-drop operation. Alternatively, right-click in the Project Schematic whitespace and select the type of analysis you want to add. During creating a new system, the name of the system is automatically highlighted and ready for editing. If you wish to change the name, simply type the new name. You can change the name later by double-clicking the name to highlight it and typing the new name, or by selecting the Rename option from the context menu (available via right-mouse click on the header cell). Figure 5.2: New Analysis System has been created for Transient Structural (ANSYS) which is shown the location of the Toolbox and Project Schematic. Also shown the step to import geometry. If necessary, define appropriate engineering data for your analysis. Right click the Engineering Data cell, and select Edit, or double-click the Engineering Data cell. The Engineering Data workspace appears, where you can add or edit material data as necessary. Attach geometry to your system or build a new geometry in DesignModeler. Right click the Geometry cell and select Import Geometry to attach an existing model or select New Geometry to launch DesignModeler. Figure 5.3: Windows for attaching geometry from SolidWorks 2009 file to the system. Define all loads and boundary conditions. Right click the Setup cell and select Edit. The appropriate application for the selected analysis type will open the Mechanical application. Set up your analysis using that applications tools and features. You can solve your analysis by issuing an Update, either from the data-integrated application youre using to set up your analysis, or from the ANSYS Workbench GUI. 5.3 Engineering Data Engineering Data is a resource for material properties used in an analysis system. The Engineering Data workspace is designed to allow you to create, save, and retrieve material models, as well as to create libraries of data that can be saved and used in subsequent projects and by other users. Engineering Data can be shown as a component system or as a cell in any Mechanical analysis system. When viewed as a cell in a Mechanical analysis system, the workspace shows the material models and properties pertinent to that systems physics. To access Engineering Data: Insert an Engineering Data component system or a Mechanical system into the Project Schematic. Select Edit from the Engineering Data cells context menu, or double-click the cell. The Engineering Data workspace appears. From here, navigate through the data for the analysis system, access external data sources, create new data, and store data for future use. Figure 5.4: The Engineering Data workspace is designed to allowed to create, save, and retrieve material models. 5.4 Geometry Use the Geometry cell to import, create, edit or update the geometry model used for analysis. For this analysis, the geometry has been import from SolidWorks 2009 assembly file format .SLDASM to the DesignModeler and there no need to be redraw again and proceed to the next step. Before Attaching CAD geometry to the Mechanical application, specifying several options that determine the characteristics of the geometry you choose to import. Figure 5.5: Selecting desired length unit option before start DesignModeler workspace. Procedure attaching CAD geometry to the Mechanical application in condition CAD system is running: Select the Geometry cell in an analysis system schematic. Right-click on the Geometry cell listed there. Double-click on the Model cell in the same analysis system schematic. The Mechanical application opens and displays the geometry. If required, set geometry options in the Mechanical application by highlighting the Geometry object and choosing settings under Preferences in the Details view. Figure 5.6: DesignModeler workspace with successfully imported from SolidWorks 2009 assembly file format which can be adjust as desired. 5.5 Stiffness Behaviour In addition making changes to the material properties of a part, designate a parts Stiffness Behaviour as flexible or rigid. Setting a parts behaviour as rigid essentially reduces the representation of the part to a single point mass thus significantly reducing the solution time. For this analysis, the cylindrical workpiece will be a rigid body and thus both top and bottom clamp will be define as flexible body. This is because the analysis itself is to determine the response of the clamping to the time-vary load. A rigid part will need only data about the density of the material to calculate mass characteristics. Note that if density is temperature dependent, density will be evaluated at the reference temperature. For contact conditions, Youngs modulus has been specified. Figure 5.7: Shown the Details view for rod 16-2-1 changing the Stiffness behaviour of the cylindrical workpiece to the Rigid. 5.6 Define Connections Connections include contact regions, joints, springs, or beams. Contact conditions are formed where bodies meet. When an assembly is imported from a CAD system, contact between various parts is automatically detected. In this analysis there are only two type of connection that will be used which is contact regions and joints. 5.6.1 Contact Regions The differences in the contact settings determine how the contacting bodies can move relative to one another. This is the most common setting and has the most impact for this analysis. Most of these types only apply to contact regions made up of faces only. Bonded: This is the default configuration and applies to all contact regions (surfaces, solids, lines, faces, edges). If contact regions are bonded, then no sliding or separation between faces or edges is allowed. No Separation: This contact setting is similar to the bonded case. It only applies to regions of faces (for 3-D solids) or edges (for 2-D plates). Frictionless: This setting models standard unilateral contact; that is, normal pressure equals zero if separation occurs. It only applies to regions of faces (for 3-D solids) or edges (for 2-D plates). A zero coefficient of friction is assumed, thus allowing free sliding. Rough: Similar to the frictionless setting, this setting models perfectly rough frictional contact where there is no sliding. It only applies to regions of faces (for 3-D solids) or edges (for 2-D plates). Frictional: In this setting, two contacting faces can carry shear stresses up to a certain magnitude across their interface before they start sliding relative to each other. It only applies to regions of faces. The model defines an equivalent shear stress at which sliding on the face begins as a fraction of the contact pressure. Once the shear stress is exceeded, the two faces will slide relative to each other. The coefficient of friction can be any non-negative value. Choosing the appropriate contact type depends on the type of problem that are trying to solve. Modelling the ability of bodies to separate or open slightly is important and/or obtaining the stresses very near a contact interface is important, nonlinear contact types (Frictionless, Rough, Frictional) has been considered to be used. However, using these contact types results in longer solution times and can have possible convergence problems due to the contact nonlinearity. When determining the exact area of contact is critical, finer mesh has been considered to be used (using the Sizing control) on the contact faces or edges that will be explain on the next sub chapter. Friction Coefficient: Allows you to enter a friction coefficient. Displayed only for frictional contact applications. Scope Mode: Read-only property that displays how the contact region was generated. Automatic Program automatically generated contact region. Manual Contact region was constructed or modified by the user. Behavior: Sets contact pair to one of the following: Asymmetric: Contact will be asymmetric for the solve. All face/edge and edge/edge contacts will be asymmetric. Asymmetric contact has one face as Contact and one face as Target (as defined under Scope Settings), creating a single contact pair. This is sometimes called one-pass contact, and is usually the most efficient way to model face-to-face contact for solid bodies. The Behavior must be Asymmetric if the scoping includes a body specified with rigid Stiffness Behavior. Symmetric: (Default) Contact will be symmetric for the solve. Auto Asymmetric: Automatically creates an asymmetric contact pair, if possible. This can significantly improve performance in some instances. When you choose this setting, during the solution phase the solver will automatically choose the more appropriate contact face designation. Of course, you can designate the roles of each face in the contact pair manually. Figure 5.8: Shown are the summary of the connection in Worksheet view including contact information, joint DOF checker, and joint information. 5.6.2 Setting Contact Conditions Manually Manual contact regions represent contact over the entire extent of the contact scope, for example, faces of the contact region. Procedure to set contact regions manually: Click the Connections object in the Tree Outline. Click the right mouse button and choose Insert> Manual Contact Region. You can also select the Contact button on the toolbar. A Contact Region item appears in the Outline. Click that item, and under the Details View, specify the Contact and Target regions (faces or edges) and the contact type. See the Contact and Target topics in the Scope Settings section for additional Contact Region scoping restrictions. 5.7 Joints A joint typically serves as a junction where bodies are joined together. Joint types are characterized by their rotational and translational degrees of freedom as being fixed or free. For all joints that have both translational degrees of freedom and rotational degrees of freedom, the kinematics of the joint is as follows: Translation: The moving coordinate system translates in the reference coordinate system. If your joint is a slot for example, the translation along X is expressed in the reference coordinate system. Once the translation has been applied, the center of the rotation is the location of the moving coordinate system. 5.7.1 Types of Joints You can create the following types of joints in the Mechanical application: Fixed Joint Revolute Joint Cylindrical Joint Translational Joint Slot Joint Universal Joint Spherical Joint Planar Joint General Joint Bushing Joint 5.7.2 Applying Joints Procedure to add a joint manually: After importing the model, highlight the Model object in the tree and choose the Connections button from the toolbar. Highlight the new Connections object and choose either Body-Ground> {type of joint} or Body-Body> {type of joint} from the toolbar, as applicable. Highlight the new Joint object and scope the joint to a face. Reposition the coordinate system origin location or orientation as needed. The Body Views button in the toolbar displays Reference and Mobile bodies in separate windows with appropriate transparencies applied. You have full body manipulation capabilities in each of these windows. Configure the joint. The Configure button in the toolbar positions the Mobile body according to the joint definition. You can then manipulate the joint interactively (for example, rotate the joint) directly on the model. Consider renaming the joint objects based on the type of joint and the names of the joined geometry. Display the Joint DOF Checker and modify joint definitions if necessary. Create a redundancy analysis to interactively check the influence of individual joint degrees of freedom on the redundant constraints. Procedure to move a joint coordinate system to a particular face: Highlight the Coordinate System field in the Details view of the Joint object. The origin of the coordinate system will include a yellow sphere indicating that the movement mode is active. Select the face that is to be the destination of the coordinate system. The coordinate system in movement mode relocates to the centroid of the selected face, leaving an image of the coordinate system at its original location. Click the Apply button. The image of the coordinate system changes from movement mode to a permanent presence at the new location. Procedure to change the orientation of a joint coordinate system: Highlight the Coordinate System field in the Details view of the Joint object. The origin of the coordinate system will include a yellow sphere indicating that the movement mode is active. Click on any of the axis arrows you wish to change. Additional handles are displayed for each axis. Click on the handle or axis representing the new direction to which you want to reorient the initially selected axis. The axis performs a flip transformation. Click the Apply button. The image of the coordinate system changes from movement mode to a permanent presence at the new orientation. You can change or delete the status of the flip transformation by highlighting the Reference Coordinate System object or a Mobile Coordinate System object and making the change or deletion under the Transformations category in the Details view of the child joint coordinate system. When selecting either a Reference Coordinate System object or a Mobile Coordinate System object, various settings are displayed in the Details view. 5.8 Meshing In this stage, the model need to be mesh in order to analyze the model. The goal of meshing in ANSYS Workbench is to provide robust, easy to use meshing tools that will simplify the mesh generation process. These tools have the benefit of being highly automated along with having a moderate to high degree of user control. 5.8.1 Physics Based Meshing When the Meshing application is launched from the ANSYS Workbench Project Schematic, the physics preference will be set based on the type of system being edited. For a Mechanical Model system as in this analysis, the Mechanical physics preference is used. For a Mesh system, the physics preference defined in Tools> Options> Meshing> Default Physics Preference is used. Upon startup of the Meshing application from a Mesh system, the Meshing Options panel shown below in figure 5.5. This panel allows to quickly and easily set meshing preferences based on the physics are prepared to be solved. Remove the panel after startup, the panel can be display again by clicking the Options button from the Mesh toolbar. Figure 5.9: Meshing option in Mechanical application. The first option the panel allows to set is Physics Preference. This corresponds to the Physics Preference value in the Details View of the Mesh folder. Setting the meshing defaults to a specified physics preference sets options in the Mesh folder such as Relevance Center, midside node behavior, shape checking, and other meshing behaviors. ANSYS Workbench meshing capabilities, arranged according to the physics type involved in the analysis. For this analysis, Mechanical physics is used, the preferred meshers for mechanical analysis are the patch conforming meshers (Patch Conforming Tetrahedrons and Sweeping) for solid bodies and any of the surface body meshers. 5.8.2 Using 3D Rigid Body Contact Meshing This section describes the basic steps for using 3D rigid body contact meshing. Procedure to define a 3D rigid body for contact meshing: Open the model in the Mechanical application. In the Tree, expand the Geometry object so that the body objects are visible. Click on the body that you want to define as a rigid body. In the Details> Definition view for the body, change the value of the Stiffness Behavior control to Rigid. If you wish to control the mesh method, insert a mesh method by right-clicking on the Mesh object in the Tree and selecting Insert> Method. In the Details View, scope the mesh method to the rigid body. If desired, change the value of the Element Midside Nodes control. Generate the mesh by right-clicking on the Mesh object in the Tree and selecting Generate Mesh. Figure 5.10: meshing result for current design analysis. 5.9 Establish Analysis Settings In transient structural analysis includes a group of analysis settings that allow to define various solution options customized to the specific analysis type, such as large deflection for a stress analysis. Default values are included for all settings. Procedure to verify/change analysis settings in the Mechanical application: Highlight the Analysis Settings object in the tree. This object was inserted automatically when you established a new analysis in the Create Analysis System overall step. Verify or change settings in the Details view of the Analysis Settings object. These settings include default values that are specific to the analysis type. Accept these defaults. In this analysis involves the use of steps, by refering to the procedures presented below. Procedure to create multiple steps: Highlight the Analysis Settings object in the tree. Modify the Number of Steps field in the Details view. Each additional Step has a default Step End Time that is one second more than the previous step. These step end times can be modified as needed in the Details view. Adding more steps simply by adding additional step End Time values in the Tabular Data window. . Figure 5.11: The following demonstration illustrates adding steps by modifying the Number of Steps field in the Details view Procedure to Specifying Analysis Settings for Multiple Steps: Create multiple steps following the procedure To create multiple steps above. Most Step Controls, Nonlinear Controls, and Output Controls fields in the Details view of Analysis Settings are step aware, that is, these settings can be different for each step. Activate a particular step by selecting a time value in the Graph window or the Step bar displayed below the chart in the Graph window. The Step Controls grouping in the Details view indicates the active Step ID and corresponding Step End Time. Figure 5.12: The following demonstration illustrates turning on the legend in the Graph window, entering analysis settings for a step, and entering different analysis settings for another step. To specify the same analysis setting(s) to several steps, select all the steps of interest as follows and change the analysis settings details. To change analysis settings for a subset of all of the steps from the Tabular Data window: Highlight the Analysis Settings object. Highlight steps in the Tabular Data window using either of the following standard windowing techniques: Ctrl key to highlight individual steps. Shift key to highlight a continuous group of steps. Click the right mouse button in the window and choose Select All Highlighted Steps from the context menu. Specify the analysis settings as needed. These settings will apply to all selected steps. To specify analysis settings for all the steps: Click the right mouse button in either window and choose Select All Steps. Specify the analysis settings as needed. These settings will apply to all selected steps. Figure 5.13: The following demonstration illustrates multiple step selection using the bar in the Graph window, entering analysis settings for all selected steps, selecting only highlighted steps in the Tabular Data window, and selecting all steps. Figure 5.14: The Worksheet tab for the Analysis Settings object provides a single display of pertinent settings in the Details view for all steps. 5.10 Joint Load When using joints in a Transient Structural (ANSYS) analysis, use a Joint Load object to apply a kinematic driving condition to a single degree of freedom on a Joint object. Joint Load objects are applicable to all joint types except fixed, general, universal, and spherical joints. For translation degrees of freedom, the Joint Load can apply a displacement, velocity, acceleration, or force. For rotation degrees of freedom, the Joint Load can apply a rotation, angular velocity, angular acceleration, or moment. The directions of the degrees of freedom are based on the reference coordinate system of the joint and not on the mobile coordinate system. A positive joint load will tend to cause the mobile body to move in the positive degree of freedom direction with respect to the reference body, assuming the mobile body is free to move. If the mobile body is not free to move then the reference body will tend to move in the negative degree of freedom direction for the Joint Load. For the joint with the applied Joint Load, dragging the mouse will indicate the nature of the reference/mobile definition in terms of positive and negative motion. Procedure to apply a Joint Load: Highlight the Transient environment object and insert a Joint Load from the right mouse button context menu or from the Loads drop down menu in the Environment toolbar. From the Joint drop down list in the Details view of the Joint Load, select the particular Joint object that you would like to apply to the Joint Load. You should apply a Joint Load to the mobile bodies of the joint. It is therefore important to carefully select the reference and mobile bodies while defining the joint. Select the unconstrained degree of freedom for applying the Joint Load, based on the type of joint. You make this selection from the DOF drop down list. For joint types that allow multiple unconstrained degrees of freedom, a separate Joint Load is necessary to drive each one. Joint Load objects that include velocity, acceleration, rotational velocity or rotational acceleration are not applicable to static structural analyses. Select the type of Joint Load from the Type drop down list. The list is filtered with choices of Displacement, Velocity, Acceleration, and Force if you selected a translational DOF in step 3. The choices are Rotation, Rotational Velocity, Rotational Acceleration, and Moment if you selected a rotational DOF. Specify the magnitude of the Joint Load type selected in step 4 as a constant, in tabular format, or as a function of time using the same procedure as is done for most loads in the Mechanical application. On Windows platforms, an alternative and more convenient way to accomplish steps 1 and 2 above is to drag and drop the Joint object of interest from under the Connections object folder to the Transient object folder. When you highlight the new Joint Load object, the Joint field is already completed and you can continue at step 3 with DOF selection.

The solution has been carried out on the local machine. Since transient solutions can take significant time to complete, a status bar is provided that indicates the overall progress of solution. More detailed information on solution status can be obtained from the Solution Information object which is automatically inserted under the Solution folder for all analyses. Figure 5.16: More detailed information on solution status can be obtained from the Solution Information in Worksheet view. The overall solution progress is indicated by a status bar. In addition the Solution Information object has been used which is inserted automatically under the Solution folder. This object allows to: View the actual output from the solver, Graphically monitor items such as convergence criteria for nonlinear problems and Diagnose possible reasons for convergence difficulties by plotting Newton-Raphson residuals. 5.12 Review Results For this transient structural analysis, the interested will be in total deformation and maximum shear results. The Results in the Mechanical Application will show as figure and tabular data. Procedure to add result objects in the Mechanical application: Highlight a Solution object in the tree. Select the appropriate result from the Solution context toolbar or use the right-mouse click option. Figure 5.17: Shown the right-click mouse option to add result in Mechanical application for Total Deformation. Procedure to review results in the Mechanical application: Click on a result object in the tree. After the solution has been calculated, review and interpret the results in the following ways: Contour results Displays a contour plot of a result such as stress over geometry. Vector Plots Displays certain results in the form of vectors (arrows). Probes Displays a result at a single time point, or as a variation over time, using a graph and a table. Charts Displays different results over time, or displays one result against another result, for example, force vs. displacement. Animation Animates the variation of results over geometry including the deformation of the structure. Stress Tool to evaluate a design using various failure theories. Fatigue Tool to perform advanced life prediction calculations. Contact Tool to review contact region behavior in complex assemblies. Beam Tool to evaluate stresses in line body representations.

Engineering disasters :: essays research papers

On February 1, 2003, the Space Shuttle Columbia was lost due to structural failure in the left wing. On take-off, it was reported that a piece of foam insulation surrounding the shuttle fleet's 15-story external fuel tanks fell off of Columbia's tank and struck the shuttle's left wing. Extremely hot gas entered the front of Columbia's left wing just 16 seconds after the orbiter penetrated the hottest part of Earth's atmosphere on re-entry. The shuttle was equipped with hundreds of temperature sensors positioned at strategic locations. The salvaged flight recorded revealed that temperatures started to rise in the left wing leading edge a full minute before any trouble on the shuttle was noted. With a damaged left wing, Columbia started to drag left. The ships' flight control computers fought a losing battle trying to keep Columbia's nose pointed forward.   Ã‚  Ã‚  Ã‚  Ã‚  It’s very hard to say what steps, if any, could have been taken to prevent the Space Shuttle Columbia disaster from occurring. When mankind continues to â€Å"push the envelope† in the interest of bettering humanity, there will always be risks. In the manned spaceflight business, we have always had to live with trade-offs. All programs do not carry equal risk nor do they offer the same benefits. The acceptable risk for a given program or operation should be worth the potential benefits to be gained. The goal should be a management system that puts safety first, but not safety at any price. As of Sept 7th, 2003, NASA has ordered extensive factory inspections of wing panels between flights that could add as much as three months to the time it takes to prepare a space shuttle orbiter for launch. NASA does all it can to safely bring its astronauts back to earth, but as stated earlier, risks are expected.   Ã‚  Ã‚  Ã‚  Ã‚  On August 14th, 2003, a major blackout swept across portions of the northeastern United States and Canada. It was reported that a series of equipment outages in the Midwest led to uncontrolled cascading outages of power transmission lines and generators serving parts of the Northeast, Midwest and Canada. Automatic protective systems operated to open circuits and shut down power plants to prevent further spread of the outages. This is very similar to what happened in The Great Northeast Blackout of 1965. In both situations, the â€Å"grid system† shut down one generator in line at a time to protect a surge from the station before it.

Macroeconomics

Macroeconomics refers to issues which influence a countries growth in terms of effecting positive impact. Microeconomic stability refers to the situation where by a country’s economic conditions are favorable and therefore conditions are conducive for growth. Population growth is often portrayed as causing poverty and environmental degradation, and thus population control is seen as a means of improving living standards. There is a growing concern amongst governments that the rate of population growth in most developing countries if not checked could continue jeopardizing the development in those countries by straining the budgets of those already struggling economies. Introduction. Population growth has been a subject of research for many decades as governments and other stakeholders seek means to bring population under check for it is widely assumed that it is related to poverty and environmental degradation. This paper explores the interrelatedness of population growth, poverty, and environment from a general perspective. Population growth implies the increase in the number of human beings in a given population per unit time (Lia & Jesse, 1998). Even though population growth can refer to increases of number of members in any given species, this paper shall limit itself to the discussion of human population. Population growth can be attributed to several aspects such as immigration and due to births which is viewed as a natural process. According to estimates from expert, the population growth in the world is currently at 200,000 people per day. Out of the current growth estimates, over 70 % of the increase is taking place in the developing countries. It is further estimated that, in the next 30 – 40 years, 2. 6 billion people will be added to today’s world estimate population of 6billion people. Currently, 65 percent of all worlds’ population lives on less than a dollar a day, in other words, in abject poverty. This indicates a positive relationship between and population growth and poverty in some areas. The relationship between the two variables lies in the fact that, human population depends on the environment for survival. If production remains constant over along period of time but in turn the population keeps on increasing, it gets to a point where the land can support no more people therefore any additional population is bound to suffer from want. This is especially so in the developing world where the main economic activity is dependent on land resources such agriculture. It is worthy noting that, population can also affect environment in other ways like the sprouting up of slums as a result of disproportionate population growth. This in turn causes people to turn into environmentally unsustainable practices to earn income. On the other side this poses a threat to health since in some cases it strains urban infrastructure for instance the city of Nairobi, the city was designed to cater for a population of 1. million people, the current population is 3 times more. The resulting effect is that, the infrastructures as well as social amenities are overstretched and unless expanded proportionally, such pose negative challenges to the environment. It is not fair to link all population growth to poverty and environmental degradation. Taking the case of some Asian countries, they have experienced a population growth and at the same t ime, improved living standards attributed to booming economies. On the other hand, a country may experience population growth without the growth impacting negatively on the environment as long as corrective measures are taken to prevent environmental degradation. Effects of population in rural areas. Clearing forest or virgin land to pave way for cultivation to support the excess population is the commonest effect of population growth on environment. This becomes an environmental concern in that it may touch on water catchment areas as well as steep lands therefore catalyzing soil erosion. The other effect could be ecological displacement of animal and plant species from their natural habitats. On the other hand population growth may result to poverty in that if the population depends on the land for income, population growth may mean over sharing of resources meaning that productivity of the land is affected ( Silanga, 2003p. 565). This scenario is especially common in sub Saharan Africa where a big percentage of the population live in rural areas. However, not all such environment woes should be associated with population growth. Effects of population in urban areas. This is of relevance since over half of the world population live in urban settlements and it is in the urban setting whereby population growth rate is high something occasioned by immigration as well as natural process. An exponential population growth may not reflect in jobs creation something which means that more and more people fall into the population trap since they do not have meaning full employment and are forced to live in semi permanent houses in slum areas . Environment may be affected by pollution resulting from economic and industrial processes. Role of population control and population growth. Population control refers to the methods applied to populations to reduce the rate of increase of individuals in a population. Family planning is the commonest method. It involves use of biological methods such as pills, hormone injection as well as tubal ligation. It controls population growth in that, individuals can control their reproduction patterns and avoid giving births to unwanted and unplanned babies. This has proved successful almost every where in the world with some countries reporting negative population growths. If proper population control measures are effected, the problems associated with population growth are solved hence the relevance of population control to population growth. Conclusion. The population – environment – poverty axis is a complex microeconomic issue phenomena which requires further research especially due to the fact that other factors affect the situation and any objective study must look into other factors in play as well. Meanwhile there s need for controlled population growth to check on population growth whose effect in most cases is negative.

The Atomic Bomb Essays

The Atomic Bomb Essays The Atomic Bomb Essay The Atomic Bomb Essay There has been a long standing debate on why the atomic bomb was used to defeat Japan.The threat of Russian advancement in Europe and in Asia was enough to worry the top officials in the United States and British governments. Wherever the Russians moved through they took for themselves.The imminent invasion of mainland Japan and the allied casualties that came with it were also a factor in the decision to drop the bomb, as said in document A.The dropping of the bomb was not entirely used to stop the Russian advancement. If the allied forces had invaded mainland Japan, many lives on both sides would have been lost.Most probably more than were lost in the bombing of Hiroshima and Nagasaki put together.The tactics that the allies had used up to this point had cost hundreds of thousands of lives onboth sides.This was when the Japanese only had maybe two or three thousand men on an island; whereas on the mainland millions of people who would fight until their death to protect their cou ntry.Can you imagine if the Americans invaded mainland Japan where they had not only soldiers to fight against but the citizens of Japan loyal to Hirohito?Massive destruction, immense loss of life, and prolonging of the war until late 1946, as stated in document A, would result from invading on foot Revenge also played a role in the decision to bomb Japan.The Japanese were not following the Geneva convention in regards to treatment of prisoners of war.Which says that the prisoners are not to be put through torture of the psychological or physical nature. The Japanese did these things anyway, they would decapitate American prisoners, or they would shove bamboo shoots under their fingernails.The American government also wanted revenge for the surprise attack on Pearl Harbor.No warning was given by the Japanese to the Americans and no war was declared until after the incident.

The Flowers Essay

The Flowers Essay The Flowers Essay "...the days had never been as beautiful as these...each day a golden surprise." Surprise is the element Alice Walker presents in her story "The Flowers." It is at the heart of the meaning of this story which is driven forward by imagery, setting, and diction. In the beginning of the story, Walker utilizes diction that creates an atmosphere of euphoric childhood innocence. Myop, the main character, "skipped lightly." Walker describes the harvests, which evince "excited little tremors" in Myop as she anticipates the new day. This jocund diction continues into the second paragraph. Specifically, Myop feels "light and good" in the heat of the warm sun. In addition, ten year old Myop creates her own world in which nothing exists "but her song." In line 8, the use of onomatopoeia, "tat-de'ta'ta" reinforces the idea of a happy, carefree youth. Paragraph three, however, marks a small yet significant shift in the passage. Walker begins the paragraph with "Turning her back on the rusty boards of her family's sharecropper cabin, Myop..." Myop's world is not behind her, but moves forward to the familiar woods. As the story progresses, there is a significant shift in paragraphs four and five. Walker begins to prepare the reader for her profound conclusion. While Myop has often explored the woods behind the house with her mother, today she sets out alone and "made her own path." As she walks through the woods, she cautiously keeps an eye out for snakes. The solitude of her journey, and the possibility of danger, builds suspense and prepares the reader for the dark surprise of the ending. The diction of paragraphs four and five also contributes to the sudden shift in the passage. While the diction in the beginning was blithe, describing "beautiful," the language in paragraph five is negative, foreshadowing the conclusion. Specifically, Myop is disoriented by the, "strangeness of the land." It was "not as pleasant" as her usual expeditions. Furthermore, words such as "gloomy" and "damp" reiterate the dark setting and prepare the reader for

Mending Wall of robert frost Essay Example | Topics and Well Written Essays - 1000 words

Mending Wall of robert frost - Essay Example We wonder from before we even begin to read the poem, what could be a mending wall? Does it talk of a wall that mends itself? Frost's "wall" is a metaphoric representation of something much more substantial than just a lifeless pile of stones. This wall can be associated with many things. It may represent a barrier, a boundary between two unlike existence. It may speak of segregation, of differentiation, of the negative connotation of being different from one another. It is something that keeps one thing from one labyrinth to reach another. This mystic feel embedded on the title arouses interest from the unknowing reader. Since there is so much a wall implies to be, the interest to know more about what this wall could possibly pertain to leads the reader to dig further and unfold each word that follows. Reading the first few lines of the poem, the reader finds out how "something" dislikes the erection of the wall. It is as if this "something" purposely deconstructs the wall to the po int that two individuals may pass through it side by side. On the 6th line of the poem "I have come after them and made repair", Frost uses "I", him speaking on the first person's point of view. His use of "I" implies not only of him as the writer telling a story but it symbolizes anyone as an individual. It is his way of giving the reader that sense of belongingness to the poem that creates the connection of the reader to the piece. This connection makes it much easier for the reader to relate to what the writer is trying to relay. Frost's imagist-like approach in the usage of simple and precise imagery is with great depth in meaning. The 12th line, "I let my neighbor know beyond the hill", tells the reader that the wall is dividing two neighbors. They meet occasionally to reconstruct the wall again; stone by stone they pile them back to its original form. This speaks of two different people or it may speak of a larger number of dissimilar groups of individuals constantly building walls against each other to keep one another from getting across. In this world, we people build barriers due to our fear of being engulfed by the other. Sometimes we rebuild the walls our forefathers have placed without even wondering what the wall is really for, just like the neighbor in the poem. As the poem progresses, the first person "I" started to question what the walls are for. On the 23rd to the 26th line, he stated: There where it is we do not need the wall: He is all pine and I am apple orchard. My apple trees will never get across. And eat the cones under his pines, I tell him. On the 27th line, the neighbor answered, 'Good fences make good neighbors'. It becomes all the more puzzling to "I". What is there to keep from each other? There are no cows to wall in or wall out. The poem concludes that even if there is this "something" that persistently destroys the wall, the neighbor continues to stand up for "his father's saying". The "wall" symbolizes the unwillingness of t he people to accept each other's differences as stated in the last lines of the poem. For the analysis of such a literary piece, the theme is certainly an important element. The theme plays an important role for the analysis of a poem with such a depth in meaning. Frost uses a similar style used by imagist. The use of free verse and precise imagery with the use of simple and direct words that can easily be associated to the scene or picture the writer tries to portray. The 40th and 41st lines of the poe

Different view of Death Essay Example | Topics and Well Written Essays - 1250 words

Different view of Death - Essay Example Although death has been part of life for a long time, people have failed to acknowledge that death is inevitable. Living in denial concerning death has, therefore, existed as a common aspect of humanity. Lack to accept that death is an inevitable part of humanity is a major aspect that characterizes the two poems. This essay will, therefore, investigate the different views of death according to the two poems. Although the two poets agree on the inevitability of death, they have varying views concerning people’s preparedness towards death and our role in waiting for the inevitable death. According to Mary, death is the main challenge that affects humanity. Mary considers humans as helpless creatures in relation to death. Therefore, the only thing that people can do is to wait or prepare for their death. The poem When Death Comes shows that the author is concerned about the nature of life when death finally finds her. Unlike Mary, Donne considers death helpless thing though inev itable. According to the poet, people have a chance to challenge death. The poet view life as an opportunity to challenge death (Online-literature web). The work that people do during their life is a form of preparation for our death. The poet argues that people have a chance to challenge death by not dying as poor people. ... Unlike Mary Oliver, John Donne believes that life is a form of transformation from one form of life to the other. On the other hand, Mary has different views towards life and death. Her poem shows uncertainty about life and death. In the third line of When Death Comes, it is claimed, â€Å"death comes like a bear in autumn† (Panhala web). This line implies that she is not concerned with life after death as much as she is concerned with the nature of her death. Although death is inevitable, it is the only chance that humans have to come close to nature. Despite the numerous technological developments about humanity, it has been difficult to find or come up with a remedy for death. The two poets reflect this phenomenon. Death is the only thing that human beings have in common with the rest of nature. People start life the same way as the rest of nature but go through different process as compared to other living organisms. However, like other living organisms, we all have to mee t our death. The basic reason why people investigate death results from the fear that people have concerning death. Although most people do not fear their own deaths, it is evident that people fear losing a loved one. The fear of death is a common aspect that differentiates the views of the two poets concerning death. According to Donne, people should not be afraid of death because they have a chance of dealing with it. Donne considers people to have a chance of facing death or doing something about death. This indicates that the poet is not afraid of death or implications of death in his own life or the life of a loved one. On the other hand, Mary’s poem expresses her fears concerning the inevitable death and its implication in her life and the life of
