Properly addressing the performance issues presented in database systems is and has been a significant technological challenge, this due to the uncontrolled fluctuation of user requests. Being able to predict the behaviour of such systems can greatly improve their performance. Several prediction methods, such as linear regression and autoregressive moving average, among others, have extensively been...
Safeguards and security systems for nuclear facilities include material control and accounting (MC&A) and a physical protection system (PPS) to protect against theft, sabotage and other malevolent human acts. The insider threat is most often addressed as part of the evaluation of a facility's PPS. A PPS is evaluated using probabilistic analysis of adversary paths on the basis of detection, delay,...
This paper presents the design considerations and the implementation of a cd-cd buck-boost converte, which can process the energy transferred from the ultra capacitors (UC) bank and batteries to the load (motor drive system of an Electric Vehicle EV). The UC bank is used as auxiliary source to supply the motor drive system which allows recovering the energy generated during the regenerative breaking;...
Performance prediction is valuable in different areas of computing. The popularity of lease-based access to high performance computing resources particularly benefits from accurate performance prediction. Most contemporary processors are employing multiple computing cores, which complicates the task of performance prediction. In this paper, we describe the methodology employed for predicting the performance...
This project involves asking three sets of engineering management students to develop group projects integrating simulation and optimization in different ways and assessing their absolute and relative educational effectiveness. These approaches are: a) Ask students to repeatedly simulate, using a conventional simulation tool, Witness?? in this case, a system whose design criteria are modified according...
