...based on elliptic curves over finite fields. The elliptic curves defined over finite fields are used in elliptic curve cryptography since a practical digital system can handle only finite number of values. In finite fields the binary extensions fields are ideal, because of the ease with which they can be implemented in a digital system in comparison with other finite fields. The main advantage of elliptic curve cryptography is that it offers higher security with smaller key size in comparison with other existing schemes like RSA etc. Elliptic curve cryptography because of its small key size has smaller latency and lesser computational/hardware complexities...

Implementing the automated baggage handling in the middle of the project made it even more complex. Denver after being behind schedule for 18 months the Airport finally opened in February 1995. Once completed the airport had 5 runaways an 88 gates. The baggage handling system of the airport was initially built for United Airlines whom insisted on the system in the earlier planning stages. Denver officials agreed the automated baggage system will be a great addition to the airport; however not just for United Airlines concourse but all concourses in the airport. Boeing Airport Equipment(BAE) was contracted for building the system by officials in Denver long after the construction on the airport began. When the airport opened it had both the automated, a back-up for the automated system and conventional baggage handling system in place. Unfortunately, the project at Denver International...

...2013 SR-rm-o22-Final Currently Riordan Manufacturing uses a system within their HR department that is complicated and disconnected because employees must submit changes in writing on certain forms, which are then entered in by a clerk. This process is not only troublesome, but also vulnerable for security breaches. This paper will discuss the request from Riordan Manufacturing’s Human resources department to unite the current hosts of HR tools into one application by describing what key stakeholders in Riordan Manufacturing requirements would be gathered from, describe the information-gathering techniques, and systems analysis tools used to evaluate the project, identify factors that will guarantee successful gathering of information required for the project, explain what the scope of the project is and why it is important, lastly, describe the areas of project feasibility that are examined in the analysis phase of the SCLC. Stakeholders in Riordan Manufacturing Riordan Manufacturing is in need of a system that will place all HR components into one secure centralized location. To resolve all inefficiencies within the current system, it is essential that information is gathered as much as possible to identify already known and potential issues that need to be corrected. Reviewing current policies and procedure documents for the existing system will give an understating of how the present day system is functioning, in addition will be helpful in identifying key individuals...

...20 SYSTEMS DESIGN, IMPLEMENTATION AND OPERATION In chapter 18 we focused on the first phase of the Systems Development Life Cycle – Systems Analysis. Chapter 20 deals with the remaining four phases: - conceptual systems design - physical systems design - systems implementation and conversion - operation and maintenance CONCEPTUAL SYSTEMS DESIGN In the conceptual systems design phase, the developer creates a general framework for implementing user requirements and solving problems identified in the analysis phase. As shown in Figure 20-1 on page 747 HC (page 637 SC), there are three main steps in conceptual design: 1. evaluating design alternatives, 2. preparing design specifications, and 3. preparing the conceptual systems design report. [pic] Evaluate Design Alternatives There are many ways to design an AIS, so accountants and others involved in systems design must continually make design decisions. [pic] The design team should identify a variety of design alternatives and evaluate each with respect to the following standards: 1) how well it meets organizational and system objectives, 2) how well it meets user needs, 3) whether it is economically feasible, and 4) what its advantages and disadvantages are. The steering committee evaluates the alternatives. Table 20-1 on page 748 HC (page 638 SC) presents examples of conceptual and physical design considerations and their corresponding design alternatives...

...The system planning and selection stage addresses the needs or opportunities that can be achieved by an IT proposal. During this step, we must consider all current priorities that would be affected and how they should be handled. Before any system planning is done, a feasibility study should be conducted to determine if creating a new or improved system is a viable solution. This will help to determine the costs, benefits, resource requirements, and specific user needs required for completion. The development process can only continue once management approves of the recommendations from the feasibility study. Systems analysis The goal of the systems analysis is to determine where the problem is in an attempt to fix it by breaking down the system. During this phase, we determine requirements and structure them according to their interrelationships, eliminating redundancies. The end result being well defined requirements that are a good fit based on the organization’s needs and budget. System design In the system design phase, functions and operations are described. It can be broken down into two steps. Logical design (blueprint) is described independently of any computer platform and is then transformed into technology-specific details known as physical design. Design elements are intended to describe the system in great detail to developers so that they can deliver the system with minimal additional input. System Implementation & Operation During this final phase...

...in the systems development life cycle (SDLC). These phases include systems planning and selection, systems analysis, system design, and system implementation and operation. The first phase is system planning and selection, which identifies the need for building information systems. This phase also covers the scope, cost, and schedule of building information systems. The second phase is the systems analysis phase, which is the actual study of the current procedures and the requirements needed. The third phase is system design, which is broken into two parts called the logical design and physical design. The logical design concentrates on the business aspect of the system, whereas the physical design pertains to the technical specifications. Finally, the fourth phase is the system implementation and operation phase. This phase implements the system by installing the hardware or software of the system. Other forms of implementation include programming, user training, and documentation. 2. If someone at a party asked me what a business/systems analyst was and why anyone would want to be one, I would first explain what a business/systems analyst is. I would tell them that a business analyst studies the problems and needs of an organization and determines the best approach to solving those needs. I would also tell them it is a job worth wanting because it is one of the best technology jobs in the field today. 3. It is important to use systems analysis and design methodologies...

This add-in provides all the features necessary to formulate and solve small examples (www.me.utexas.edu). The material requirement planning of Riordan manufacturing is designed to supply the required material for creating the parts of electric fan in order to produce the components at each phase of assembly line production. The receiving department collects the raw material, which is processed in the molding department to make it suitable for generating parts of the fan after being polished and trimmed in the trimming department. These parts are further processed in the assembly department to make larger components such as fan blades or fan housings. The packaging departments puts each parts of the fan in right package with adequate labeling so that it can be delivered to distribution center through shipping department (University of Phoenix, 2004). Factors that might affect choosing the Hangzhou, China facility and identify possible risks associated with the facility. Disparity in Riordan system, changes in currency and taxes has also will lead to some issues with disparity and compatibility among the business systems between the independent operating locations, some of which need attention to improve business operations.
