This paper presents a two-dimensional particle-based model for the red blood cell, and uses it to compute cell deformation in simple shear and pressure-driven flows. The cell membrane is replaced by a set of discrete particles connected by nonlinear springs; the spring law enforces conservation of the membrane area to a high accuracy. In addition, a linear(More)
Sensing and communication coverage are among the most important trade-offs in Wireless Sensor Network (WSN) design. A minimum bound of sensing coverage is vital in scheduling, target tracking and redeployment phases, as well as providing communication coverage. Some methods measure the coverage as a percentage value, but detailed information has been(More)
Multi-Point Relay (MPR) mechanism is a selection algorithm to reduce the number of control packets in ad-hoc network routing protocols. This study presents a new MPR selection method using genetic algorithm (GA) while the MPR sets follow the maximal independent concept. Although original greedy algorithm works well in sparse networks, as MPR selection is an(More)
MultiPoint Relay (MPR) selection algorithm is a flooding technique for propagating a broadcast message inside an ad-hoc network which reduces the number of unnecessary broadcast messages in order to save more energy in the network, minimize the number of packet collisions, and speed up the propagation time. In this paper, we demonstrate that MPR selection(More)
Let D be a convex planar domain, symmetric about both the x-and y-axes, which is strictly contained in (−a, a) × (−b, b) = Γ. It is proved that, unless D is a certain kind of rectangle, the difference (gap) between the first two eigenvalues of the Dirichlet Laplacian in D is strictly larger than the gap for Γ. We show how to give explicit lower bounds for(More)
This paper reviews the existing localization techniques and parameters in Wireless Sensor Networks (WSNs) and few schemes are discussed in term of Terrestrial WSNs. The fundamental differences between Underwater and Terrestrial WSN are highlighted. Furthermore, the paper analyzes the few existing aquatic localization schemes and presents a discussion in two(More)
Fast and accurate distance measurement is crucial for target tracking and node localization in Wireless Sensor Networks. For short-range Underwater Acoustic Sensor Networks (UASNs), received signal strength (RSS) can give distance between acoustic devices. An extensive study on the application of the Lambert W function over RSS for distance estimation in(More)
BACKGROUND Trunk muscle fatigue has high relevance in human performance. Most authors agree that the use of the median frequency is preferred as a fatigue indicator. Most work has to date, been done on dynamic fatigue measurements, using the similarity index (SI). OBJECTIVE Repeated trunk flexion-extensions were measured using the B200 Isostation. Muscle(More)
