It is known that the competitive exclusion principle holds for a large kind of models involving several species competing for a single resource in an homogeneous environment. Various works indicate that the coexistence is possible in an heterogeneous environment. We propose a spatially heterogeneous system modeling the competition of several species for a single resource. If spatial movements a...

Modeling competing failure modes is an important problem in engineering and survival analyses. Competing are partially observed many applications often pose a modeling challenge. This study discusses the inference for assuming Burr XII distribution. In particular, we consider two modes, time data collected under hybrid type I censoring scheme. The model parameters estimated using maximum likeli...

This paper focuses on Mobile Agents as the fine vehicle of modern decision systems. Changes don’t just happen but are the result of changes in the environment, which itself is changing as a result of the changes mentioned above. In this paper the authors will look at the agents as a state of the art solution to decision-making problems of today’s highly demanding environment. Potential problems...

We describe a learning environment for high school biology called BGuILE that engages students in scientific investigations in which they can explore interesting problems in evolution and ecology. The environment supports productive inquiry by two interrelated means. First, the system structures students’ investigations, encouraging them to compare competing hypotheses, articulate predictions, ...

The selection of best Information System (IS) project from many competing proposals is a critical business activity which is very helpful to all organizations. While previous IS project selection methods are useful but have restricted application because they handle only cases with precise data. Indeed, these methods are based on precise data with less emphasis on imprecise data. This paper pro...
