Finite element analysis Essay Example | Topics and Well Written Essays - 1000 words

Finite element analysis - Essay Example It is not only used for stress analysis and deflection of solid structures, but also for problems involving heat conduction, fluid flow and electric fields. Finite element analysis (FEA) is a method which most engineers today find an essential tool that can be applied to almost any design problem prior to testing and development. This paper presents the results of a finite element analysis for the buckle of a standard lap belt used in a passenger aircraft. Figure 1 is a representation of the buckle/belt assembly. The buckle itself must be designed to withstand a 450 kg tensile load; thus, the objective of the analysis was to determine the maximum stress max of the buckle under this load and determine whether or not the design meets its objectives. Once this has been determined, a recommendation is made to proceed with testing or to begin a redesign of the buckle. Finite Element Analysis was first introduced in the 1950's and has been continually developed ever since. (FEA) is a computer-based numerical technique for calculating the strength and behaviour of engineering structures. It can be used to calculate deflection, stress, vibration, buckling behaviour and many other phenomena. It can be used to analyze either small or large-scale deflection under loading or applied displacement. It can analyze elastic deformation, or "permanently bent out of shape" plastic deformation. The computer is required because of the astronomical number of calculations needed to analyze a large structure. As mentioned, this report has been complied to document the results of the Finite Element Analysis of a buckle connection. The function of the FE Analysis was to obtain the max of the buckle connection which is based to resist 450 Kg of tension, as written in assignment. The buckle connection was designed to be made from Stainless Steel plate. A comprehensive set of properties for the specified material is shown in table 1 FIRST STEP: Material properties of Stainless Steel ASSUMPTIONSAssumptions: The first step in preparing for the analysis is to develop a list of assumptions concerning the geometry, properties, the mesh, the boundary conditions and linear and static factors. In the begging of doing this report in FEA Package there are numbers of assumptions were made which give create more imaginations as key in testing any design before test it in real life. FirstConsidering the geometry, it is assumed that the drawings provided are accurate representations of the buckle. Thickness of the buckle was assumed to be constant which led to the particular selection of the element type which allowed for a thickness criteria. Shell elements were then selected. In brief, shells form curved surfaces in space and are usually thin compared to their length. The elements selected for this analysis are assumed to be able to adequately model the part. ly Next, properties of the material were considered. It it was assumed that all material properties supplied provided by the designerin the problem statement were correct accurate and provided a true representation of the material specifiedpart. . Another assumption made was that the Homogeneous and isotropic material was homogeneous

Slavery Trade Essay Example | Topics and Well Written Essays - 1000 words

Slavery Trade - Essay Example As the report stresses various abolitionist laws were instituted, though slave trade still grew dramatically spreading to the Northern parts of the American continent.   During this time, there was a gradual growth and expansion of the cotton industry. With the tremendous expansion of the cotton industries which were mostly found in the southern part of the American continent, labor force became a challenge to the industry stakeholders. Acquiring and retaining an adequate workforce that could carry out the day to day activities within the cotton industry became a major challenge to the industry players thus they had to seek a solution.From this paper it is clear that  most of the laborers within the cotton industry at that time were of British origin and were only available as indenture servants. These laborers offered their services in the cotton fields and industry on contractual basis, thus were never reliable to the industry players. They had the tendency of signing contracts that were indenture in nature. They in return received payments in various forms for their services in cotton industries and fields. In most cases, the laborers received payment in the form of upkeep. The cotton field owners and the industry stakeholders had to offer upkeep for the laborers as payment for the services they offered in their fields and cotton industries. Either, the laborers received passage from the cotton field owners and industry owners for the services they offered.

Implicit Knowledge Assets in Healthcare Essay Example | Topics and Well Written Essays - 1500 words

Implicit Knowledge Assets in Healthcare - Essay Example In their drive towards improving efficiency and cutting cost, Knowledge Management has come as a concept with immense potential. The present case is of a Spine Unit in USA, which is in the environment as described above, and the paramount need is leveraging the potential of its two key assets, technology and knowledge in a manner which is able to enhance its efficiency and reduce costs. The Spine Care unit has rich knowledge assets comprising of surgeons and medical staffs from the disciplines of Neurology, Neuro-surgery, orthopedics, spine surgeons, psychologists, physical therapists and pathologists. It is a technology intensive unit with advanced technologies deployed at clinical side in the form of medical equipments and in the practice management side it has extensive IT facilities like Hospital Management Information System (HMIS).   The unit has well developed protocols based on data/information from NCQA, medical journals and its own systems. It is clear from the details th at the Spine Unit is not exploiting the potential of its implicit knowledge assets in a structured and strategic manner despite the fact that it has majority of KM technology in place.   The issue is to leverage the unit’s existing strength and deploy a full-fledged KM system. It is beyond doubt that knowledge and its management involves only one thing – people, all others are enablers. Larry Prusak says â€Å"Knowledge flows along existing pathways in organizations. If we want to understand how to improve the flow of knowledge., we need to understand those pathways.† [citation?] The KM solution for the Spine unit has to exploit the KM concept which creates Communities of Practice, enhances sharing and enriching knowledge, promotes networking and bonding among employees. We see a gap in people focused KM mechanisms, systems and technologies. Proposed solution The objective is to create a KM system comprising of compulsory elements and voluntary elements of KM systems. It is with the approach of leveraging and integrating the exiting assets and existing IT technology Compulsory elements: At every decision point viz. admission of patient, diagnosis, surgery, post operative care, people concerned will be required to refer to the KM system. For example while making a decision to admit the patient one will be required to access the system and system will â€Å"Push† relevant information i.e. patient history, probable diagnosis, past experiences, experts list to ensure the best decision in a quick manner.

Language & Levels Assignment Example | Topics and Well Written Essays - 750 words

Language & Levels - Assignment Example Additionally, without proper communication, the department will not be motivated to associate themselves in planning the objectives and goals of the organization. The management of communication and human resources are the questioned area when the firm is deficient despite having necessary tools. The second measurement is equipment. If the objectives and goals are well, designed and comprehended by the working team and are well motivated, but the firm is deficient, management need to revise the equipment and tools to see if they are corresponding to the productivity level. Another measurement is teamwork and the values of the organization. If the members of the department do not show a collaborative attitude towards one another, a crucial problem may arise in terms of assessing the interaction between the team members. The measurement used in out department to measure the effectiveness of the company is descriptive data. The goal of descriptive data is to describe. The numerical measures are used in telling the features about a collection of data. Some of the items that belong to descriptive data include average, kurtosis, and skewness. Conversely, in inferential data, there is use of representative subset of the population called the sample. Inferential data researched on the statistical sample (Menzefricke, 2 005). The recommendation for the organization inefficiency posted by one of my classmates is by balancing the internal process value, human relation value, rational goals value, and the open system value. The contextual and structural variables are associated with the above values. Additionally, the concern posted by another classmate on communication measurement, the organization needs to explain the goals of the company to the employs and set the kind of values that are well followed and understood by the employees. I would also suggest the company to

Practice of Research Assignment Example | Topics and Well Written Essays - 250 words

Practice of Research - Assignment Example Being one of the most challenging activities in the research process, reviewing of the available literature is an important principle. It enables the researcher come up with a researchable problem. In their book titled â€Å"Practical Research: Planning and Design,† the authors Leedy and Ormrod (2010) put forth the statement that, â€Å"the existing literature is likely to tell you what is not known in the area- in other words, what still needs to be done.† Reviewing the available literature will expose the researcher to several areas of concern with the likelihood and expectation that he or she will generate sub-problems from the material before going to the major problems. Identifying a problem related to the researchers themselves is important since it will naturally motivate them into researching more (Leedy & Ormrod, 2010). After identifying this kind of problem, the researcher should then focus on the purpose of the research at hand with the ability of developing substantial

Pros and Cons of Abortion Research Paper Example | Topics and Well Written Essays - 500 words

Pros and Cons of Abortion - Research Paper Example According to the research findings, it can, therefore, be said that to understand the phenomenon of abortion better it would be ideal to look at its pros and cons. It is believed that abortion is a justifiable act as it is a killing of a fetus and not that of a human being. A person is originated at birth and not during conception. This is a biologically proven fact and hence favor abortion. The oath of Hippocrates which the medical professionals take itself forbids abortion and hence is a malpractice. â€Å"The original text of the Hippocratic Oath, the oath that doctors traditionally take when swearing to practice medicine ethically, forbids abortions†. The U.S constitution gives liberty to live to all men and killing of one life is against nation’s proclamation. â€Å"Allowing abortion directly contradicts the Founding Fathers intentions for an inalienable right to life in this country†. It is evidently clear from the discussion that abortion having pros and cons can be defended and justified according to the situation and effect of this medical procedure. It is not possible to condemn abortion altogether as it offers va rious benefits to women. The good side of abortion is weighed more in American society and the bad effects stand as reasons for the public to defend against it.
