The purpose of this study is to design a simple, efficient, single-user multitasking kernel for real-time applications on the IBM Personal Computer. Since real-time application consists of many tasks and their order of execution cannot be predetermined, it is almost impossible to write a monolithic block of code that can meet the response time of all the tasks. By using multitasking, each task is assigned a priority based on the urgency of its response time. The kernel uses a priority-based preemptive scheduling strategy to select a new task to run, so the highest-priority task can always get to run when it is ready. The Basic Input/Output System of the PC is rewritten to be reentrant so that it can be shared by multiple tasks.

An approach to introduce the visually impaired to personal computers is presented in this thesis. The PC used for this work was an IBM PC Portable. Use of the resident software developed in conjunction with a Votrax Voice Unit can greatly simplify PC applications for the visually impaired. Further, a method to communicate with a mainframe is also presented. Almost all of the commonly used DOS application software are supported by the software presented in this thesis. Two modes of operation are possible. The advantages and differences between these two modes are considered. A detailed discussion on the software implementation is also presented. A method to develop resident programs that need to trap PC BIOS vectors is presented. It should be noted that the shell concept presents a shell of user invoked resident applications and not a group of subprograms which can be used by other applications. / M.S.

In this thesis, a PROCESSOR and a POSTPROCESSOR are developed for a plane frame analysis computer program on the IBM PC. The PROCESSOR reads the data prepared by a PREPROCESSOR and solves for the unknown joint displacement using the matrix displacement method. The POSTPROCESSOR uses the results of the PROCESSOR to obtain the required responses of the structure. A chapter on testing procedures is also provided. / Master of Science
