An intention to adopt IP protocol for future mobile communication and subsequent extension of Internet services to the air interface calls for advanced performance modeling approaches. To provide a tool for accurate performance evaluation of IP-based applications running over the wireless channels we propose a novel cross-layer wireless channel modeling approach. We extend the small-scale propa...

Performance prediction has the potential of ameliorate the student model of an Intelligent Tutoring System by predicting whether a student mastered or not a specific set of skills. Recently, it has been shown, by means of a simulated learning process, how performance prediction methods based on Matrix Factorization can be used for continuous score prediction and for sequencing contents through ...

Abstract This paper presents a modeling technique for performance evaluation of media access protocols based on semi-markovmodels. The proposed techniqueprovides accurate performance prediction while also preserving model flexibility. General traffic generation and resource holding time distributions are supported with this approach. The model is independent of the system size and is linearly s...

We present an overview of current research in performance modeling, focusing on efforts underway in the Performance Evaluation Research Center (PERC). Using some new techniques, we are able to construct performance models that can be used to project the sustained performance of large-scale scientific programs on different systems, over a range of job and system sizes. Such models can be used by...

Simulation of multicomponent systems poses many critical challenges in science and engineering. We overview some software and algorithmic issues in developing high-performance simulation tools for such systems, based on our experience in developing a large-scale, fullycoupled code for detailed simulation of solid propellant rockets. We brie y sketch some of our solutions to these issues, with f...

Magic: The Gathering (MTG, or Magic) is the oldest and most popular trading card game played today, due in part to the complex interplay of thousands of cards. In two-player games, each player constructs a "main" deck (referred to as simply 'deck' hereafter) which consists of 60 cards, allowing players to pursue an enormous number of strategies and card combinations. When experienced Magic play...
