Brain Hyperscanning, i.e. the simultaneous recording of the cerebral activity of different human subjects involved in interaction tasks, is a very recent field of Neuroscience aiming at understanding the cerebral processes generating and generated by social interactions. This approach allows the observation and modeling of the neural signature specifically dependent on the interaction between subjects, and, even more interestingly, of the functional links existing between the activities in the brains of the subjects interacting together. In this EEG hyperscanning study we explored the functional hyperconnectivity between the activity in different scalp sites of couples of Civil Aviation Pilots during different phases of a flight reproduced in a flight simulator. Results shown a dense network of connections between the two brains in the takeoff and landing phases, when the cooperation between them is maximal, in contrast with phases during which the activity of the two pilots was independent, when no or quite few links were shown. These results confirms that the study of the brain connectivity between the activity simultaneously acquired in human brains during interaction tasks can provide important information about the neural basis of the spirit of the group. © 2011 IEEE.

The human being should be awarded the championship of navigation on the planet, on the virtues that they not only have invented and manufactured the compass, GPS, aircraft, vessel, spacecraft, but also have demonstrated exceptional non-instrumental navigation skills. The Austronesian expansion from the Asian mainland into the Pacific performed by the Pacific navigators, who eventually populated the most remote islands of the Pacific about 4000 years ago, is a vivid example (Wehner 1998). However, animals, especially flying birds and insects are strong contenders. Monarch butterflies can migrate up to 2000 miles from their reproductive sites in the eastern US and Canada to their over-wintering sites in the forests of Mexico, and it is postulated that they may possess a biological equivalent of a low-resolution GPS system that is based on the magnetic field of the earth. In fact, even the long-legged ants (Cataglyphis fortis) in the Saharan desert use the dead-reckoning navigation strategy, which is attributed to the Polynesians, but the ants apparently have acquired the capability much earlier, given the relative short evolutionary history of humans. In this article, we briefly review the state-of-the-art research on insect navigation and communication used in flight and communication, with the objective to inspire cross-disciplinary studies in aerospace engineering, biology and computer science. After a brief review, we overview and identify seven cross-disciplinary research topics that may draw on inspirations from insect navigation and communication in flight and migration. These topics include: ants colony inspired swarm intelligence, honeybee inspired group decision-making, insect sociobiology, MAV/mobile robot flight control and remote control of insect flights, optimal migration strategy, Quorum sensing, and joining and collision avoidance for MAV fleet control. An interesting question one may pose is: given the rich and advanced navigation and communication t

Network dynamics, such as mobility and increase in network load, can influence the performance of aWireless Sensor Net- work (WSN). In this paper, we introduce a method which exploits design-time knowledge of the application scenario dynamics to construct a proactive run-time reconfiguration approach. The approach anticipates for the impact that predefined dynamic events can have on the performance of the WSN by switching between various modes of operation defined at design-time. A mode defines the values for the controllable parameters of the network protocol stack. Our approach explicitly differentiates between parameters that can be adapted locally, per node, and those that should be considered globally for the whole WSN. Design-time defini- tion of modes results in a very low run-time overhead as we only require detection of the mode to use and a low overhead synchronization to change global parameters. The approach is made robust by using a recovery approach for nodes un- aware of their global mode after, for example, (re-)joining the network. Experiments with an office monitoring deploy- ment and extensive simulations of a cow-health monitoring scenario show that our approach can easily be adopted by practical WSN deployments and results in a significant re- duction in resource usage, e.g., power consumption in our examples, at a very low run-time overhead cost.

Electronic Transport in Hydrogenated Amorphous Silicon

MRS Online Proceedings Library 2011年第1期70卷 119-124页

作者： M. Silver D. Adler M. P. Shaw V. Cannella J.

The puzzles regarding the magnitude of the free electron mobility in hydrogenated amorphous silicon are examined. It is suggested that high-level double injection produces a metastable increase in the carrier mobility by neutralizing positively and negatively charged defect states thereby eliminating long-range potential fluctuations. Since these defect states cannot be neutralized under low-level or single injection, they both contribute to the modulation of the conduction band and increase the free-carrier scattering. If the latter is the predominant scattering mechanism, the neutralization of charged defects directly leads to a mobility increase under double-injection conditions. We discuss the various implications of this model, and present recent experimental results in agreement with these ideas.

Network attacks have become the fundamental threat to today's largely interconnected computer system. Intrusion detection system (IDS) is indispensable to defend the system in the face of increasing vulnerabilities. While a number of information visualization software frameworks exist, creating new visualizations, especially those that involve novel visualization metaphors, interaction techniques, data analysis strategies, and specialized rendering algorithms, is still often a difficult process. To facilitate the creation of novel visualizations this paper presents a new framework that is designed with using data visualization technique for analysis and visualizes snort result data for user. The framework suggests PHP and CSS as data visualization technique and snort as intrusion detection system (IDS).

In this paper we present the development and evaluation of a parent decision support tool for a neonatal intensive care unit (NICU), known as PPADS or Physician and Parent Decision Support. The NICU interprofessional (IP) team uses advanced technology to care for the sickest infants in the hospital, some at the edge of viability. Many difficult care decisions are made daily for this vulnerable population. The PPADS tool, a computerized decision support system, aims to augment current NICU decision-making by helping parents make more informed decisions, improving physician-parent communication, increasing parent decision-making satisfaction, decreasing conflict, and increasing decision efficiency when faced with ethically challenging situations. The development and evaluation of the PPADS tool followed a five step methodology: assessing the clinical environment, establishing the design criteria, developing the system design, implementing the system, and performing usability testing. Usability testing of the PPADS tool with parents of neonates who have graduated (survived) from a tertiary level NICU demonstrates the usefulness and ease of use of the tool.

A Novel Multipath Routing Protocol for MANETs

A Novel Multipath Routing Protocol for MANETs

International Conference on Wireless Communications, Networking and Mobile Computing (WiCom)

作者： Mu'ath Obaidat M. A. Ali M. S. Obaidat Suhaib Obeidat Ihsan Shahwan Department of Electrical Engineering City College at the Graduate Center of the CUNY New York NY USA Dept. of Comput.

This paper proposes a novel multipath routing protocol for MANETs. The proposed protocol is a variant of the single path AODV routing protocol. The proposed multipath routing protocol establishes node-disjoint paths that have the lowest delays based on the interaction of many factors from different layers. Other delay aware MANETs routing protocols don't consider the projected contribution of the source node that is requesting a path into the total network load. The implication is that end to end delay obtained through the RREQ is not accurate any more. On the contrary of its predecessors, the proposed protocol takes into consideration the projected contribution of the source node into the computation of end to end delay. To obtain an accurate estimate of path delay, the proposed multipath routing protocol employs cross-layer communications across three layers; PHY, MAC and Routing layers to achieve link and channel-awareness and creates an update packet to keep the up to date status of the paths in terms of lowest delay. The performance of the proposed protocol investigated and compared against the single path AODV and multipath AOMDV protocols through simulation using OPNET. Results have shown that our multipath routing protocol outperforms both protocols in terms of average throughput, end to end delay and packet dropped.

Extracting environmental constraints to make reactive system specifications realizable

Many fatal accidents of safety critical reactive systems have occurred in unexpected situations which had not been considered during design and test phases of the systems. To prevent these accidents, reactive systems should be designed to respond appropriately to any requests of any timing from their environments. Verifying this property in specification phase reduces the development costs of safety critical reactive systems. This property of a specification is well known as realizability. If a specification was found not to be realizable, we have to determine the flaws in the unrealizable specification. Unrealizability of a specification arises from arbitrary requirements given by system designers. From a different point of view, it can be thought that the unrealizable specification implicitly imposes a precondition on the behavior of environment, which a system can not control. If it is possible to obtain the precondition in intuitively comprehensive forms, this makes it easy for system designers to understand the cause of flaws in specifications. In this paper, we propose methods for deriving constraints on the behavior of environments, which is implicitly imposed by unrealizable specifications. Instead of realizability, we use strong satisfiability which is a necessary condition for realizability, due to the fact that many practical unrealizable specifications are also strongly unsatisfiable, and strong satisfiability have the advantage of lower complexity for analysis against realizability. These methods derive constraints in propositional linear temporal logic from Büchi automata representing specifications. The expressions of derived constraints are limited to simple and intuitively comprehensive forms where only two temporal operators appear successively. We give proofs for three correctness properties of our methods, i.e. the termination property, the soundness property, and the weakest constraints derivability. We also discuss complexity of our methods. Fi
