We consider a setting where a team of humans oversee the coordination of multiple Unmanned Aerial Vehicles (UAVs) to perform a number of search tasks in dynamic environments that may cause the UAVs to drop out. Hence, we develop a set of multiUAV supervisory control interfaces and a multiagent coordination algorithm to support human decision making in this setting. To elucidate the resulting in...

Allocation of limited testing efforts to a software development project is a complex task for software managers. The challenges become difficult when the nature of the development process is considered in the dynamic environment. Numerous software reliability growth models have been proposed in last one decade to minimize the whole testing effort expenditures, but generally under static assumpt...

Grid computing is the collection of computer resources from multiple locations to reach a common goal. The grid is a special type of distributed system with non-interactive workloads that involve a large number of files. Partitioning of the application program/ software into a number of small groups of modules among dissimilar processors is an important parameter to determine the efficient util...

Current worst-case execution time (WCET) analyses do not support programs using dynamic memory allocation. This is mainly due to the unpredictable cache performance when standard memory allocators are used. We present algorithms to compute a static allocation for programs using dynamic memory allocation. Our algorithms strive to produce static allocations that lead to minimal WCET times in a su...

Modern optical fibre networks are evolving from static point-to-point connections towards meshed networks with some degree of optical transparency and capability for reconfiguration. At the same time installation and operation shall be simplified, while the availability shall be kept high. In the network design this task can be accomplished by allocation of transmission margins and by control o...

The main concern of DCS is reliability. For improving the reliability one way is proper task allocation among the nodes and load balancing is one of the best ways to improve not only reliability but throughput and minimizes execution time. In this paper, we reviewed the concept of load balancing and various mechanisms and finally compared static and dynamic load balancing. The main purpose of t...

We present several new compiler techniques employed by our interprocedural parallelizing research compiler, Panorama, to improve loop parallelization and the eeciency of memory references. We rst present an overview of the compiler and its associated memory architecture simulation environments. We then present an interprocedural array dataaow analysis, using guarded array regions, for automatic...

Models of gaze allocation in complex scenes are derived mainly from studies of static picture viewing. The dominant framework to emerge has been image salience, where properties of the stimulus play a crucial role in guiding the eyes. However, salience-based schemes are poor at accounting for many aspects of picture viewing and can fail dramatically in the context of natural task performance. T...

We demonstrate how static, energy-efficient schedules for independent, parallelizable tasks on parallel machines can be improved by modeling idle power if the static power consumption of a core comprises a notable fraction of the core’s total power, which more and more often is the case. The improvement is achieved by optimally packing cores when deciding about core allocation, mapping and DVFS...

Energy Management for multi-mode Software Defined Radio (SDR) systems remains a daunting challenge. In this paper, we focus on the issue of task allocation for multi-processor based systems with hybrid processing resources that can be reconfigured to support various operations. With the objective of minimizing energy, we present an analytical probabilistic model that considers static, dynamic, ...
