My thesis is to design a Controlled Area Network (CAN) simulator For Microsoft Windows. In a modern world we deal with complex mechanical systems that require special electronic control to guarantee ultimate safety and efficiency. These electronic control systems are responsible for monitoring subsystems within the mechanical systems. A good example of this is the motor vehicles that are being driven on the road today. These vehicles have been designed with increased safety and efficiency, such as electronic controlled anti lock breaks, fuel injection, and power control steering. To run all of these components, the car needs a very well designed protocol to be able to control series of messages being passed from one subsystem to another. To determine which message being passed has higher priority than any other messages. To deal with such circumstances, the Controlled Area Network (CAN) was designed. The purpose of the CAN simulator is to gather statistical information concerning the arbitration, message transfer, error detection, error signaling, and retransmision. The CAN simulating model will consist of one to sixty nodes. Each node is considered as a subsystem for the CAN simulator. The subsystems will be characterized as the breaks, engine, transmission, or any part of a car which needs to be connected to the CAN system. Each node will send one to ten messages through the CAN system. The CAN system will take the messages from the nodes and place them into an Arrival queue. Each node will have its own Arrival queue, and no nodes can have two messages on the bus at the same time. The messages will be sorted in the queues in the order of the time needed to be released onto the bus. There will be an internal clock that will monitor the time for when the messages are needed to be placed onto the bus. If there is a situation where two messages need to be sent at the same time, the arbitrator will determine the priority of the messages to be placed onto the bus. Once the message is on the bus, it will go to a transfer queue. Periodically, there will be an error signal sent with the message that will be detected by the error detection, and it will be required that the message to be retransmitted. At critical points on the simulation, statistical information will be gathered for an analyzation. Some examples of information to be analyzed are 1) verification of the simulation performance on a single node with a single message, 2) network load which is a rate of a utilized bus time to the total bus time, 3) network throughput which is a total number of messages that are transmitted per second, and 4) average response time which will be the average time taken by all messages to gain bus access.PLATFORM DESCRIPTIONThe computer to be used in this project will be an Intel Pentum 100 with 16 megs RAM, two 853 megabyte harddrive, and a 17 inch super VGA monitor. The user interface will be windows 3.1 application. The compiling language to be used will be Microsoft Visual C++.

With the rapid development of wireless technologies, traditional mobile devices, such as pagers and cellular phones, have evolved from a purely communications and messaging-oriented medium to one that supports mobile data communication in general and acts as an application platform. As shown in a recent survey conducted by MDA, easy access to the present-day wireless Internet has resulted in mobile devices gaining more and more attention and popularity. The growth of and demand for mobile Web applications is expected to increase rapidly in the near future, as a range of software companies and mobile device manufacturers release increasingly accessible tools for creating mobile Web application and services. From a variety of possible development environments of this kind, the author has selected and examined two leading contenders, the J2ME and the Microsoft .NET mobile Web application development environments. This document reports the product life cycle of pilot mobile web applications, designed and implemented in each host environment in tum. A feature-by-feature investigation and comparison of the J2ME and .NET environments was carried out, covering the range of issues necessary for a complete mobile Web application development life cycle. The resulting analysis addresses features and efficiencies of the application development environment and the target deployment environment, the degree to which the resultant services are compatible on a variety of platforms, and the ease with which applications can be designed to be extensible. The thesis offers an objective evaluation of the J2ME and the .NET mobile development environments, which highlights their strengths and weaknesses, and suggests guidelines for designing, creating, and deploying high quality mobile Web applications. The research uncovers no clear winner across all categories assessed. J2ME currently favours situations in which bandwidth is limited and client side processing power is relatively sufficient, it exerts the processing power of mobile devices over distributed network environments. .NET requires a less constrained network throughput, but performs adequately on clients with more limited processing power, supports a more diverse target platform range, and offers a more efficient, in terms of development time, development environment. Both technologies are likely to receive significant user support for some time.

Increasing speed of networks and worldwide availability has made the World Wide Web the most significant medium for information exchange. Web technologies have become more and more important as large and small businesses continue to make their presence on the web. Today's businesses have more than just a "face" on the worldwide web. The use of a web browser is no longer restricted to viewing static pages. Browsers are becoming more and more a standard interface to a multifaceted reign of programs that live on the worldwide web. Two main technologies stand out for the implementation of web applications, Sun Microsystems' Java 2 Enterprise Edition (J2EE) and Microsoft' Dot Net Framework. The purpose of this study is to provide an unbiased comparison of the two technologies based on performance and other software qualities.

Multi-tier enterprise systems consist of more than two distributed tiers. The design of multi-tier systems is considerably more involved than two tier systems. Not all systems should be designed as multi-tier, but if the decision to build a multi-tier system is made, there are benefits to this type of system design. CSCources is a system that tracks computer science course information. The requirements of this system indicate that it should be a multi-tier system. This system has three tiers, client, business and data. Microsoft tools are used such as Visual Basic (VB) that was used to build the client tier that physically resides on the client machine. VB is also used to create the business tier. This tier consists of the business layer and the data layer. The business layer contains most of the business logic for the system. The data layer communicates with the data tier. Microsoft SQL Server (MS SQL) is used for the data store. The database containsseveral tables and stored procedures. The stored procedures are used to add, edit, update and delete records in the database. Microsoft Transaction Server (MTS) is used to control modifications to the database. The transaction and security features available in the MTS environment are used. The business tier and data tier may or may not reside on the same physical computer or server. Active Server Pages (ASP) was built that accesses the business tier to retrieve the needed information for display on a web page. The cost of designing a distributed system, building a distributed system, upgrades to the system and error handling are examined.Ball State UniversityMuncie, IN 47306

Back in May of 1990, Windows was brought into the arena of viable operating environment due to the significant improvements Windows 3.0 made over its predecessor, Windows 2.11. Windows 3.1, another significant upgrade, was released in May, 1992. As the popularity of Windows has soared, the number of applications developed specifically for Windows has also sky-rocketed. This has translated into a huge demand for Windows programmers.Writing Windows code, however, is never an easy task. In fact, Windows has the reputation of being easy for users but hard for programmers. The difficulties in learning to program in Windows plus the increasing number of beginning Windows programmers lead to an urgent need to provide a solution to the problem: How to ease the learning curve of Windows programming?This is thus the theme of the thesis: building a comprehensive on-line Windows programming tutorial that helps ease the daunting learning curve. Through the use of interesting illustrations, example programs with on-line explanations, this tutorial makes Windows programming easier and more fun to learn.

The purpose of this thesis is to develop a software system simulating Turing machines using a Microsoft Windows' Interface.Developed in the 1930's by Alan Turing and Emil Post, Turing machines are defined as "abstract computers" . These machines seem able to solve all problems a modern computer can solve, however complex the problems may be. A Turing machine is a basic computational model for algorithms.The software provides a practical tool to students with a relative notion of Turing machines. The software contains introduction and general information on Turing machines that gives the beginner enough background to use the program. The user can create, modify or run Turing machines saved onto MS-DOS files. Some examples of Turing machines are preloaded. These examples give more help to the beginner.An on-line help facility is provided in order to direct and inform the learning student at each level of the software.The Microsoft Windows' Interface makes the software easy and friendly to use. The software has the modularity which will ease any future enhancement.

In today’s computer environments the systems are getting bigger and more complex for each day that passes by. The motivating factor for this is that the customer wants to achieve more and more with their computer systems than before. The only way to really solve this task is to use even more APIs (Application program interfaces) in their systems.     When using more APIs in a system, there is a chance that the specific system provides the same type of API twice, which of course, is a waste of storage and resources. In addition, the more APIs a system contains, the bigger the risk is for mismanagement of these APIs. In the worst case, this can result in security breaches or data leaks.  This thesis investigates specific APIs provided for a customer of Sigma IT Consulting. The aim is to evaluate and organize the APIs according to their usability criteria. The main focus of the evaluation is the available documentation which will be evaluated by a questionnaire survey distributed to senior software developers at Sigma IT Consulting in Växjö. Conclusions will then be drawn depending on the result from the survey, and we can then see if Azure API management (which is a service to make a system more user – friendly) is accurate in its way of organizing with the API usability as the main focus! Unfortunately, Azure API management did not have any possibility what so ever to customize the API placement in a system, and the only way the APIs are organized is in alphabetical order. Therefore, a prototype with even more sorting functionality than Azure API management will also be presented in this thesis.

New hardware devices are continually being released to the public by hardware manufactures around the world. For these new devices to be usable under a PC operating system, device drivers that extend the functionality of the target operating system have to be constructed. This work examines and compares the device driver architectures currently in use by two of the most widely used operating systems, Microsoft’s Windows and Linux. The IEEE1394 (high speed serial bus) device driver stacks on each operating system are examined and compared as an example of a major device driver stack implementation, including driver requirements for the upcoming IEEE1394.1 bridging standard.

The hypercube is one of the most versatile and efficient networks yet discovered for parallel computation. It is well suited for both special-purpose and general-purpose tasks, and it can efficiently simulate many other networks of the same size. The size of subgraphs can be used to estimate the efficient communications of hypercube computer systems.The thesis investigates induced subgraphs of a hypercube, discusses sizes of subgraphs, and provides a formula to give bounds on the size of any subgraph of the hypercube.The concept of spanning graphs and line graphs is useful for studying properties of graphs. An MS WINDOWS based graphical system is developed which allows the creation and display of graphs and their spanning graphs, line graphs and super line graphs.

The nature of Internet and Intranet Web applications has changed from a static content-distribution medium into an interactive, dynamic medium, often used to serve multimedia from back-end object-relational databases to Web-enabled clients. Consequently, developers need to make an informed technological choice for developing software that supports a Web-based application for distributing multimedia over networks. This decision is based on several factors. Among the factors are ease of programming, richness of features, scalability, and performance. The research focuses on these key factors when distributing images from an Oracle9i database using Java Servlets, JSP, ASP, and ASP.NET as the server-side development technologies. Prototype applications are developed and tested within each technology: one for single image serving and the other for multiple image serving. A matrix of recommendations is provided to distinguish which technology, or combination of technologies, provides the best performance and development platform for image serving within the studied envirorunent.

In order for an agent to be considered both an interface agent and autonomous, it follows that there must be some part of the interface that the agent must operate in an autonomous fashion. The user must be able to directly observe autonomous actions of the agent and the agent must be able to observe actions taken autonomously by the user in the interface The ability of a software agent to operate the same interface operated by the human user, and the ability of a software agent to act independently of, and concurrently with, the human user will become increasingly important characteristics of human-computer interaction. Agents will observe what human users do when they interact with interfaces, and provide assistance by manipulating the interface themselves, while the user is thinking or performing other operations. Increasingly, applications will be designed to be operated simultaneously by users and their agents [1]. This study is motivated by the need to solve a problem of human resource optimization in the first year informatics practical course as presented by the R.A.U. Standard Bank Academy for Information Technology. The major aim being the development of a prototype system capable of automatically grading first year Microsoft Visual Basic.Net applications. The prototype system will ultimately render assistants obsolete in the grading process and free the assistants to help students with problems related to the informatics course. Developing the envisaged prototype requires much preliminary reading on artificial intelligence and its applications, more specifically autonomous interface agent architecture. Case-based reasoning and machine learning has been identified as having great potential and applicability in the development and implementation of the envisaged prototype and for this reason these topics will provide a foundation on which to build this dissertation.
