SWOT Analysis- United Airlines 12 5. SWOT Analysis- Delta Airlines 14 6. Analysis 15 7. Recommedations 16 8. Work Cited 17 INTRODUCTION In evaluating two companies who have had to restructure their business models to evolve to changing times I choose United Airlines and Delta Airlines. Both companies filled for bankruptcy in the early 2000’s and since then have nursed their company back to health and to becoming the industries leaders for airlines. I choose these two airlines because I frequently use them to travel. My family are also huge travelers and I spend a lot of time looking for the best deals for them. United Airlines filed for bankruptcy in 2002 and would become the longest case in the United States lasting until 2006. The airline was able to get their reorganization plan approved by the United States government by restructuring their management plan. In the restructure they also changed how their bonus plan was organized for successful executives. They also had to evaluate their employee’s efficiency while on the clock. They were able to reduce their workforce from 100,000 employees to half of that. Finally the airline had to revaluate the routes they were taking and then see which ones...

...with a bicycle frame. This can be examined by developing a 2D model of a loaded bicycle frame with three different weights. This can later be compared to a 3D model to determine its accuracy. Experimental Procedure: The bicycle contains various strain gauges along the frame. These strain gauges are necessary in order to measure the stress throughout the frame, as loads are added. Three different loads: 110, 160, and 240lbs, were applied in the experiment. LabVIEW is used to measure these stresses. Modern bicycles are made of Aluminum, Young’s Modulus is 9860ksi and Poisson’s ratio is .36. The components of the bicycle used are labeled below. Figure 1: Simple Bicycle Frame (3D Representation) As you can see below, the bicycle can be easily represented using 2D truss elements. Figure 2: 2D Truss Representation with Applied Load (F) Length values of each frame are listed below: Frame | Length (in) | Top Tube | 22.0 | Down Tube | 26.5 | Seat Tube | 17.5 | Chain Stays | 17.0 | Seat Stays | 19.5 | Table 1: Frame Length Values The eight strain gauges were analyzed, four on the down tube and four on the top tube, all centered on the tube and oriented: Strain # | Location on Bicycle | 0 | down tube, top of frame, axial | 1 | down tube, top of frame, hoop | 2 | down tube, bottom of frame, axial | 3 | down tube, bottom of frame, hoop | 4 | top tube, top of frame, axial | 5 | top tube, top of frame, hoop | 6 | top tube, bottom of frame, axial | 7 |...

...Organizational analysis is the process of reviewing the development, work environment, personnel and operation of a business or another type of association.[1] This review is often performed in response to crisis, but may also be carried out as part of a demonstration project, in the process of taking a program to scale, or in the course of regular operations. Conducting a periodic detailed organizational analysis can be a useful way for management to identify problems or inefficiencies that have arisen in the organization but have yet to be addressed, and develop strategies for resolving them.[1] Organizational analysis focuses on the structure and design of the organization and how the organization's systems, capacity and functionality influence outputs. Additional internal and external factors are also accounted for in assessing how to improve efficiency. Undertaking an organizational analysis is helpful in assessing an organization's current well-being and capacity, and deciding on a course of action to improve the organization's long-term sustainability. A restructuring of an Organization may become necessary when either external or internal forces have created a problem or opportunity for improvement in efficiency and effectiveness. When performing an organizational analysis, many details emerge about the functions and capacity of the organization. All of these details can make pinpointing what is efficient and inefficient difficult. Using theoretical organizational models can help...

...DESIGN AND ANALYSIS OF A CHASSIS FOR A 60 TON PAY LOAD Abstract: As the chassis frame forms the backbone of a heavy vehicle, its principal function is to safely carry the maximum load for all designed operating conditions. To achieve a satisfactory performance, the construction of a chassis is the result of careful design and rigorous testing. Various manufacturers have individual design concepts and different methods of achieving the desired performance standards for the complete chassis, not all chassis components are interchangeable between various makes and models of vehicles. So, there is no standard design for chassis frame. Even though start with the chassis frame design start with selection of the section for side rails and cross members. In this paper we have designed a chassis for storage cum resting fixture. Storage cum resting fixture is a structure of length 11000mm & width 2300mm, used to store cylindrical specimens of various sizes and weights in horizontal configuration. The storage cum resting fixture is used to carry the propellant stored in the cylindrical specimens. The trolley fixture should be designed for a maximum pay load of 60 tons. The Objective of my project is to design a chassis for a pay load of 60 Tons. The design process involves manual design calculations, 3d modeling using UNIGRAPHICS software and analysis to validate the design. Ansys package has been implemented to perform the structural analysis. ...

...on their case management practice. Design: Semistructured interviews were conducted utilizing the Bolman—Deal Organizational Model. This model identifies four frames of an organization: symbolic, human resources, political, and structural. Sample: A purposive sample of nine nurses and one social worker was selected to participate in comprehensive interviews. Results: Data analysis identified two main themes. The first theme was the presence of organizational structural barriers to providing case management. The second theme was the lack of political influence by the nurses to change the structure of the organization; hence, their skills could be more completely utilized. Conclusions: Public health nurses who work in child welfare will need to systematically analyze their role within the organization and understand how to work in Òhost settings.Ó Nursing educators need to prepare public health nurses to work in non-health care settings by teaching organizational analysis. Key words: child protective services, organization, public health nursing. The purpose of this exploratory qualitative descriptive study was to investigate how public health nurses working in the child welfare system in a large metropolitan county in California view the organization. The study utilized the Bolman—Deal Organizational ModelÕs (1997) four frames for organizational analysis: symbolic, political, human resource, and structural. Public health nurses have joined social workers in providing care...

...Tutorial on Classification Igor Baskin and Alexandre Varnek Introduction The tutorial demonstrates possibilities offered by the Weka software to build classification models for SAR (Structure-Activity Relationships) analysis. Two types of classification tasks will be considered – two-class and multi-class classification. In all cases protein-ligand binding data will analyzed, ligands exhibiting strong binding affinity towards a certain protein being considered as “active” with respect to it. If it is not known about the binding affinity of a ligand towards the protein, such ligand is conventionally considered as “nonactive” one. In this case, the goal of classification models is to be able to predict whether a new ligand will exhibit strong binding activity toward certain protein biotargets. In the latter case one can expect that such ligands might possess the corresponding type of biological activity and therefore could be used as ‘’hits” for drug design. All ligands in this tutorial are described by means of an extended set of MACCS fingerprints, each of them comprising 1024 bits, the “on” value of each of them indicating the presence of a certain structural feature in ligand, otherwise its value being “off”. Part 1. Two-Class Classification Models. 1. Data and descriptors. The dataset for this tutorial contains 49 ligands of Angeotensin-Converting Enzyme (ACE) and 1797 decoy compounds chosen from the DUD database. The set of "extended" MACCS fingerprints is used as...

...1. Introduction 1.1 Background of Apple Inc The corporate history of Apple Inc is considered as a history of passion (Schermerhorn 2010, p.438). It was begun by a pair of Stevens, i.e. Steven Wozniak and Steven Jobs together with Ronald Wayne, who combined their professional skills to create Apple Computer [1]on 1st April 1976 with the release of the Apple I, the first Apple computer, in the same year. Since the establishment, Apple has been focusing on the consumer electronics, computer software, and personal computers and the best-known products include Iphone, Ipad, Mac line of computers and other hardware and software products. And according one of the most recent brand study carried out by the global brands agency Millward Brown, Apple has overtaken Google as the world’s most valuable brand (Bbc.co.uk 2011). Figure 1 Steve Jobs and the most recent Iphone 4 in white Source: Yohe 2010 1.2 Industrial environment introduction As claimed by Hill and Jones (2008, p.100) that for the last 20 years, fast growth of the power of the computer has greatly attributed to the high extent of innovation and a turbulent environment in the personal computer industry.

...IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, VOL. 18, NO. 3, MARCH 2000 535 Performance Analysis of the IEEE 802.11 Distributed Coordination Function Giuseppe Bianchi Abstract—Recently, the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slotted exponential backoff. This paper provides a simple, but nevertheless extremely accurate, analytical model to compute the 802.11 DCF throughput, in the assumption of finite number of terminals and ideal channel conditions. The proposed analysis applies to both the packet transmission schemes employed by DCF, namely, the basic access and the RTS/CTS access mechanisms. In addition, it also applies to a combination of the two schemes, in which packets longer than a given threshold are transmitted according to the RTS/CTS mechanism. By means of the proposed model, in this paper we provide an extensive throughput performance evaluation of both access mechanisms of the 802.11 protocol. Index Terms—802.11, collision avoidance, CSMA, performance evaluation. I. INTRODUCTION N recent years, much interest has been involved in the design of wireless networks for local area communication [1], [2]. Study group 802.11 was formed under IEEE Project 802 to recommend an international standard for Wireless Local...

...should generate a higher return than stocks carrying a market equity beta of 0.90. Firm-specific risk is any source of risk that does not affect the covariability of a firm’s returns with the market. People examined the analysis of financial risk associated with the use of leverage along the four dimensions, which would be listed later. In these four dimensions, the first two dimensions of risk are firm-specific risk and the third dimension of risk as systematic risk. The four dimensions are: first with respect to time frame: We examined the analysis of a firm’s ability to pay liabilities coming due the next year (short-term liquidity risk analysis) and its ability to pay liabilities coming due over a longer term (long-term solvency risk analysis). The financial ratios examined a firm’s need for cash and other liquid resources relative to amounts coming due within various time frames. Secondly, with respect to the degree of financial distress: We emphasized the need to consider risk as falling along a continuum from low risk to high risk of financial distress. Firms with a great deal of financial flexibility fall on the low side of this continuum. Most credit analysis occurs on the low- to medium-risk side of this continuum. Most bankruptcy risk analysis occurs on the medium- to high-risk side of this continuum. Thirdly with respect to covariability of returns with other securities in the market: We briefly highlighted the use...

...are known to exhibit a semi-rigid behaviour? Journal of Constructional Steel Research, 60, 2004, 713-723. Annotated model Executive Summary This report evaluates the assumption that joints which display semiPurpose rigid behaviour can be modelled as frictionless pinned joints in building design calculations. The idealisation is evaluated by Method comparing computer simulations incorporating this assumption with experimental test data for the actual structure. The results Results show that the idealisation is safe and is usually conservative in estimating the structural strength; however these conclusions are limited to cases where the joints display large deformations before rupture of the bolts or welds. Only in few, probably unrealistic Conclusion cases will this assumption lead to unsafe results which overestimate strength. It is recommended that three conditions are necessary for the safety of semi-rigid joints: joints must show enough ductility, Recommendations welds must be well designed in order to avoid premature fracture and the design of the joint must be such that the rotation is practically possible. 1. Introduction Background In building design, joints are classified as pinned, semi-rigid or rigid depending on their stiffness relative to the framing in which they are used. Engineers consider some joints as pinned in their structural analysis, even though it is common knowledge that all joints exhibit some rotational constraint. For example beam-tocolumn joints...
