The IEEE 802.16 protocol, also known as WiMAX, has been designed to support long-range communications with high bitrates, using two operation modes: Point-to-Multi-Point (PMP) and Mesh. In the mesh mode, Subscriber Stations (SSs) can directly communicate with each other, thus forming a tree, and can be used to forward other's data packets in a multi-hop fashion. On the contrary, in the PMP mode only one hop communication toward the Base Station (BS) is allowed. In this paper, we investigate the performance of the mesh mode by proposing an algorithm for constructing the WiMAX mesh tree. Our algorithm increases routes' effective throughput by splitting long links into multiple shorter ones. We show through simulations that this approach leads to improving the throughput capacity of WiMAX-based wireless mesh networks. [less ▲]

From a hybrid systems point of view, we provide a modeling framework and a trajectory tracking control design methodology for juggling systems. We present the main ideas and concepts in a one degree-of-freedom juggler, which consists of a ball bouncing on an actuated robot. We design a hybrid control strategy that, with only information of the ball’s state at impacts, controls the ball to track a reference rhythmic pattern with arbitrary precision. We extend this hybrid control strategy to the case of juggling multiple balls with different rhythmic patterns. Simulation results for juggling of one and three balls with a single actuated robot are presented. [less ▲]

Purpose of review Patients in a vegetative or minimally conscious state continue to pose problems in terms of diagnosis, prognosis and treatment. Despite recent waves of international media attention following Terri Schiavo's death and the 'miracle recovery' of Terry Wallis, research efforts aimed at increasing our knowledge about brain function in these conditions remain scarce and must address a series of difficulties, including financial and ethical barriers. Here we review current possibilities and limitations of clinical and para-clinical assessment of chronic disorders of consciousness. Recent findings During the past year the field has witnessed publication of significant, yet isolated, case reports in top-ranking journals, including Science and Nature. Such milestone reports and other impressive recent technological advances in the study of vegetative and minimally conscious patients reveal enthralling areas of science that must find their way to clinical medical reality. Summary Consciousness is a subjective experience whose study has remained within the purview of philosophy for millennia. That has finally changed, and empirical evidence from functional neuroimaging offers a genuine glimpse at a solution to the infamous mind-body conundrum. New technological and scientific advances offer the neurological community unique ways to improve our understanding and management of vegetative and minimally conscious patients. [less ▲]

We explore collective behavior in biological systems using a cooperative control framework. In particular, we study a hysteresis phenomenon in which a collective switches from circular to parallel motion under slow variation of the neighborhood size in which individuals tend to align with one another. In the case that the neighborhood radius is less than the circular motion radius, both circular and parallel motion can occur. We provide Lyapunov-based analysis of bistability of circular and parallel motion in a closed-loop system of selfpropelled particles with coupled-oscillator dynamics. [less ▲]

Abstract—Motivated by recent observations of fish schools, we study coordinated group motion for individuals with oscillatory speed. Neighbors that have speed oscillations with common frequency, amplitude and average but different phases, move together in alternating spatial patterns, taking turns being towards the front, sides and back of the group. We propose a model and control laws to investigate the connections between these spatial dynamics, communication when sensing is range or direction limited, and convergence of coordinated group motions.

This paper represents the very basic work of bio-climatic classification of north-east India into warm and humid, cool and humid and cold and cloudy zones. This classification is extremely useful to the building design for wide range of objectives such as climate responsive building design, building energy conservation, thermal comfort, out door design conditions, etc. This classification is based on the meteorological data collected over a period of more than 30 years, from Regional Meteorological Centre, Guwahati, India from 30 stations spread all over the region. Psychometric charts are prepared for each bio-climatic zone to assess the potential of solar passive design strategies for residential buildings. [less ▲]

Like many other deltas, Egypt is particularly vulnerable to the effects of global warming. A relative rise in sea-level of 1 m would submerge much of the delta region within 30 km of the coast during the next 100 years. Rising sea levels would have significant long-term impacts on physical, biological and socio-economic conditions of the Nile Delta. These include the damage and destruction of buildings near beaches, erosion of beaches, salt-water intrusion, and flooding more than 1,200 km2 of Egypt’s Delta Coastline. [less ▲]

L’apprentissage de la lecture constitue une étape importante pour les enfants; certains d’entre eux l’attendent avec impatience, d’autres le redoutent. La lecture est en effet un processus complexe, on le sait: l’apprenti lecteur doit apprendre à maîtriser différentes stratégies mais aussi à les coordonner. Les obstacles peuvent donc se situer à différents niveaux et les difficultés peuvent s’ancrer très tôt dans la scolarité, d’autant que les élèves ne sont pas tous égaux lorsqu’ils débutent dans l’apprentissage de la lecture-écriture. Laisser passer l’occasion d’identifier les forces sur lesquelles on pourra s’appuyer, ou les points faibles pour y réagir de manière adéquate dès les étapes initiales de l’apprentissage peut être lourd de conséquences: les difficultés s’accumulent et augurent d’un parcours d’échecs qui peut brouiller les élèves précocement et parfois définitivement avec la lecture, faute d’un diagnostic et d’une remédiation mise en place en temps utile. On connaît toute l’importance de la lecture dans les autres apprentissages scolaires. Même s’il est vrai qu’on apprend à lire toute sa vie, un échec dans les apprentissages de base de la lecture ne se surmonte pas facilement. Or, les outils manquent dans les écoles pour poser un diagnostic fin des difficultés auxquelles certains élèves se heurtent dès leurs premiers pas dans les apprentissages. Les enseignants se sentent démunis face à la réalisation d’un diagnostic précis: ils disent qu’ils peuvent très tôt repérer un élève qui ne suit pas ou n’accroche pas, mais ne savent pas toujours détecter précisément ce qui fait obstacle. Par ailleurs, un sentiment de malaise par rapport à la gestion des difficultés et des différences de niveaux de lecture des élèves a été mis en évidence dans une enquête1 menée auprès d’un échantillon représentatif d’un millier d’enseignants de 1re et 2e années primaires. Très peu d’enseignants estiment être bien préparés pour faire face aux difficultés en lecture et avoir bénéficié d’une formation suffisante en matière de remédiation. Au-delà d’aides plus spécialisées (par l’intervention de logopèdes, par exemple) et du soutien que certains parents peuvent donner à leur enfant, il apparaît essentiel d’apporter une aide aux enseignants responsables de l’apprentissage initial de la lecture.

A method is proposed to characterize contraction of a set through orthogonal projections. For discrete-time multi-agent systems, quantitative estimates of convergence (to a consensus) rate are provided by means of contracting convex sets. Required convexity for the sets that should include the values that the transition maps of agents take is considered in a more general sense than that of Euclidean geometry. [less ▲]
