Item Modular approach to performance testing in Java(Texas Tech University, 2002-12) Khoat, Siddhartha SPerformance testing is frequently neglected by the engineers during the development phase. The traditional approach of performance evaluation as an afterthought has resulted in severe delays and in loss of productivity. The commercially available testers are generic in nature and do not adapt well to the ever- changing requirements during the early phases of software development lifecycle. This research proposes a new modular approach to performance testing. In addition it also examines the feasibility of development-time performance testing in large scale enterprise applications. The architecture is simple, scalable and based on the first principles of object-oriented programming. The choice of Java as the programming language makes the framework flexible, maintainable and platform independent. The tester performed at 98 percent accuracy under test scenarios.Item Performance analysis of distributed object-oriented computing techniques(Texas Tech University, 1999-12) Belkoura, Mohamed AmineThe aim of this thesis work is to test different performance criteria of three standards object-oriented distributed compudng techniques, which are CORBA, COM-DCOM, and Java RMI. Published benchmarks and test codes will be used to measure quantitative parameters, such as the delay and the throughput. The thesis project contains two sets of comparison tests. The first part focus on tesdng different CORBA implementations under the same condition, in order to match each implementadon with a specific class of distributed applicadons. The second part is a comparison between CORBA, COM/DCOM, and Java RMI, in regard to delay and throughput. This thesis project examines and evaluates distributed object oriented techniques. The quantitadve comparison provides to developers a valuable source of information that will help choosing the right middleware for the applicadon need.Item Representation of control systems using Java(Texas Tech University, 1998-12) Conn, James NealNot availableItem Virtual control systems laboratory(Texas Tech University, 2001-05) Navaratna, Channa Nisantha BandaraDuring the development of a control system, simulations can verify that the implemented algorithms work as expected. Smaller parts of the implementation can be tested before they are put together into a complete control system. In an existing plant, simulation can be used for optimization of the control system and control parameters can be tuned without affecting the real process. The goal of this thesis has been to develop applets to be used in a web page to simulate control systems. These web pages are to be mainly used as a tool for educational purposes to develop web-based control designs. It also provides some control algorithm routines and some routines to handle matrix operations. Control system simulation on the web environment is a research area where few studies have been done. Possibilities for simulations on the Internet are immense. With Java language's flexibility to execute on any computer, routines written in Java can easily be ported into many computers running many operating systems.
