Abstract
With the widespread applications of electronic learning (e-Learning) technologies to education at all levels, increasing number of online educational resources and messages are generated from the corresponding e-Learning environments. Nevertheless, it is quite difficult, if not totally impossible, for instructors to read through and analyze the online messages to predict the progress of their students on the fly. The main contribution of this paper is the illustration of a novel concept map generation mechanism which is underpi ....etc

Abstract—This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. Most existing ad hoc routing protocols are susceptible to node mobility, especially for large-scale networks. Driven by this issue, we propose an efficient Position-based Opportunistic Routing (POR) protocol which takes advantage of the stateless property of geographic routing and the broadcast nature of wireless medium. When a data packet is sent out, some of the neighbor nodes that have overheard th ....etc

Abstract—
We consider an end-to-end approach of inferring probabilistic data-forwarding failures in an externally managed overlay
network, where overlay nodes are independently operated by various administrative domains. Our optimization goal is to minimize the
expected cost of correcting (i.e., diagnosing and repairing) all faulty overlay nodes that cannot properly deliver data. Instead of first
checking the most likely faulty nodes as in conventional fault localization problems, we prove that an optimal strategy should start wit ....etc

Toward Practical Opportunistic Routing With Intra-Session Network Coding for Mesh Networks
Abstract
We consider opportunistic routing in wireless meshnetworks. We exploit the inherent diversity of the broadcastnature of wireless by making use of multipath routing. Wepresent a novel optimization framework for opportunistic routingbased on network utility maximization (NUM) that enables usto derive optimal flow control, routing, scheduling, and rateadaptation schemes, where we use network coding to ease therouting problem. All pr ....etc

ABSTRACT:

Using ab initio density functional theory (DFT) calculations, we demonstrate two molecular OR gates that are able to process binary signals encoded as molecular potentials. Thus, the possibility to implement logic gates of _1 nm is demonstrated. The advantage of this approach to post-microelectronics technologies is the tremendous low-power dissipation, the small feature size of molecular devices, and the compatible nature of input and output signals that would allow the implementation of complex logic.

Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).

Abstract:

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorith ....etc

ABSTRACT
To achieve desirable biomimetic motion, actuators must be able to reproduce the important features of natural
muscle such as power, stress, strain, speed of response, efficiency, and controllability. It is a mistake, however, to
consider muscle as only an energy output device. Muscle is multifunctional. In locomotion, muscle often acts as an
energy absorber, variable-stiffness suspension element, or position sensor, for example. Electroactive polymer
technologies based on the electric-field-induced deformation of polymer d ....etc
