Delay has been found as one of the most crucial factors determining the Quality of Experience (QoE) in synchronous video-mediated communication. The effect has been extensively studied for dyadic conversations and recently the study of small group communications has become the focus of the research community. Contrary to dyads, in which the delay is symmetrically perceived, this is not the case for...
Online social communities often exhibit complex relationship structures, ranging from close friends to political rivals. As a result, persons are influenced by their friends and foes differently. Network applications can benefit from accompanying these structural differences in propagation schemes. In this paper, we study the optimal influence propagation policies for networks with positive and negative...
Opportunistic scheduling of delay-tolerant traffic has been shown to substantially improve spectrum efficiency. To encourage users to adopt delay-tolerant scheduling for capacity-improvement, it is critical to provide guarantees in terms of completion time. In this paper, we study application-level scheduling with deadline constraints, where the deadline is pre-specified by users/applications and...
Participatory sensing projects typically rely on time-based polling or volunteer-initiated data collection. We have investigated the potential benefits of managed sensing, in which requests for information are targeted at particular volunteers as they visit locations of interest. We performed a study comprising of 24 volunteers who were asked to report sightings of bees whilst visiting gardens over...
The problem of minimizing the decoding delay in Generalized instantly decodable network coding (G-IDNC) for both perfect and lossy feedback scenarios is formulated as a maximum weight clique problem over the G-IDNC graph in . In this letter, we introduce a new lossy G-IDNC graph (LG-IDNC) model to further minimize the decoding delay in lossy feedback scenarios. Whereas the G-IDNC graph represents...
To create a portal to transfer knowledge may seem easy. However, our experience shows that, in order for a user to accept the learning portal as their primary source of knowledge, a lot of attention to detail is necessary in how the content and interface is built. In order for users to accept a learning portal and to use it as their primary source of knowledge, not only must the content be arranged...
Discourse markers, a group of pragmatic elements, are used widely in our daily communication. Among these markers, well is found to be the most frequently used one in conversation. Although much research has been carried out on its theoretical bases such as its definition, functions and categorizations, few studies have taken a multimodal approach in analyzing this marker. The aim of the present study...
Mobility model is an essential factor in evaluating routing protocols designed for Delay Tolerant Networks. The use of inappropriate mobility models for evaluating a routing protocol in DTN can significantly affect its performance and the applicability in real world. In literature, many of existing mobility models designed for their own routing protocols are somewhat inappropriate since they are not...
In this paper, we present a novel technique for online testing of feedback bridging faults in the interconnects of the cluster based FPGA. The detection circuit will be implemented using BISTER configuration. We have configured the Block Under Test (BUT) with a pseudo-delay independent asynchronous element. Since we have exploited the concept of asynchronous element known as Muller-C element in order...
