The Bluetooth radio system is an ideal communications tool for lightweight autonomous mobile robots but little research interest has been targeted at this application. We present in this paper an environment which allows behavior-based autonomous mobile robotic simulation to take advantage of synthetic Bluetooth communications. Two components comprise our system. A highly adaptable mobile robot...

portable information appliances, the extraordinary power consumption ratio of memory accesses promotes importance of efficient memory system design to an ultimate. We address the following issues: how to minimize memory bandwidth requirement for instruction accesses, and how to minimize memory access delay, again for instruction accesses. Then we propose to move dynamic branch handler (e.g., br...

This paper presents a wideband jamming emitter localization method based on the fusion of multiple direction-ofarrivals (DOAs) and time-difference-of-arrival(s) (TDOA(s)) obtained from multiple unmanned-aerial-vehicles (UAVs). In this technique, we assume that multiple trajectory controllable UAVs are available and they are equipped with smart antennas to estimate the emitter’s angle (DOA) with...

IVG is a GPS-based Inter-Vehicle Communication protocol used for alarm message dissemination among vehicles in a highway in risk situations. It is based on the principle of wireless ad hoc networks. In this paper, we propose an improvement to IVG towards supporting its interoperability in environments where vehicles “GPS-U” without GPS devices are present. It is also the case, because of obstac...

Currently, literature on organizational boundaries is at the center of a heated debate, characterized by a shift from a transactional approach to a broader immaterial perspective centered on the concept of boundless organizations. However, the overestimation of the effects of contemporary dematerialization on business processes can lead to the progressive neglect of the existence of corporate b...

In this paper, a procedure has been presented to develop fragility curves of structures equipped with optimal variable damping or stiffness semi-active tuned mass dampers (SATMDs). To determine proper variable damping or stiffness of semi-active devices in each time step, instantaneous optimal control algorithm with clipped control concept has been used. Optimal SATMDs have been designed based ...

When a failure occurs on some edge of a telecommunication network, the amount of traac going through this edge has to be rerouted on some reserve paths. This leads to the restoration problem which consists in determining minimum cost spare capacities to be used for rerouting purposes. We consider here a special case due to the introduction of digital cross-connects in some of the nodes of the n...

This paper deals with the modeling of gas-liquid flow in distillation columns equipped with structured packing. The devices are seen as bi-structured porous media and a macro-scale model is proposed taking into account this specific geometry. In this model, the two liquid films, one-per-sheet, are treated separately and are allowed to exchange matter at the vicinity of the contact points betwee...

Coordination among protective devices in distribution systems will be affected by adding distributed generators (DGs) to the existing network. That is attributed to the changes in power flow directions and fault currents magnitudes and directions due to the insertion of DG units in the distribution system, which may cause mis-coordination between protection devices. This paper presents an appro...

This paper addresses the problem of cylinder burned gas rate transient control of VVA equipped Diesel engines. This problem is of importance for NOx emissions reduction. The proposed strategy coordinates existing low-level intake manifold burned gas rate and VVA controllers. To determine relevant control actions, a model of cylinder filling phenomenon is determined. It expresses, under the form...
