In the past years computing has been moving from the sequential world to the parallel one, from centralised organisation to a decentralised. In parallel programming the goal of the design process cannot be reduced to optimise a single metrics like for example speed. While evaluating a parallel program a problem specific function of execution time, memory requirements, communication cost, implem...

As supercomputers continue to grow in scale and capabilities, it is becoming increasingly difficult to isolate processor and system level causes of performance degradation. Over the last several years, a significant number of performance analysis and monitoring tools have been built/proposed. However, these tools suffer from several important shortcomings, particularly in distributed environmen...

A method for optimal continuous insulin therapy for diabetes patients has been sought since the early 1970s. Although technical and medical advances have been made, a fully automated artificial pancreas to replace the functions of the natural organ is still a research aim. This review compares recent control algorithms for type 1 diabetic patients which automatically connect continuous glucose ...

Abstract: In this contribution, we study the performances of discrete event systems modeled by (max,+) automata. More precisely, new representations for (max,+) automata are first proposed. From these, several performance indicators can be derived, in particular the maximum time execution and a minorant of the minimum execution time for a sequence of length n. Finally these results are discusse...

The optimization of the modulation for open service (OS) signal located at L1 band in the working of global navigation satellite system (GNSS) signals design has some particularity, since this signal has huge amount of potential users and very wide application fields. For different application requirements, the expectations for performance and complexity are difference. A competitive OS signal ...

One of the most critical issues in battery-powered and energy-constrained wireless sensor networks (WSN) is how to make the most of energy efficient strategies to improve system performance. In this paper, the system performance is represented by energy-efficiency and dataefficiency of the network. For the case where all the wireless nodes are distributed uniformly, we put forward an optimizati...
