Teleoperation system performances suffer from the delays in the communications line. These delays are usually variable time delays. The customary wave variable technique used for constant time delays cannot provide satisfactory results to stabilize the system under variable delays. Another problem occurs in the position tracking performance of the limitedworkspace teleoperation systems. Althoug...

Multiple Bluetooth piconets operating in the globally available 2.4-GHz Industrial, Scientific and Medical (ISM) band are likely to co-exist in a physical environment, supporting applications such as wireless earphones, keyboards etc. An independently operating Bluetooth piconet will inevitably encounter the interference from collocated piconets, which results in individual piconet as well as o...

To estimate how much an agent can be trusted, its trustworthiness needs to be assessed. Usually, poor performance of an agent leads to a decrease of trust in that agent. This is not always reasonable. If the environment interferes with the performance, the agent is possibly not to blame for the failure. We examine which failures can be called excusable and hence must not be seen as bad performa...

With more and more devices being introduced into vehicles to provide additional driving functionality, driving experience is seemingly getting more complex and frustrated due to an influx of individual messages. To help manage the information, individuals need a mechanism to orchestrate the operations of the in-vehicle devices so that such frustration can be eased. In this study, the authors pr...

Transmission diversity schemes have recently emerged in wireless systems as an attractive solution in order to mitigate fading effects. Space-time block codes (STBC) with two antennas can provide similar order diversity as maximal-ratio receiver combining (MMRC). In this paper transmit diversity scheme using STBC with two and four antennas is applied for the EDGE/EGPRS system and its results ar...

A trace of a workload’s system calls can be obtained with minimal interference, and can be used to drive repeatable experiments to evaluate system configuration alternatives. Replaying system call traces alone sometimes leads to inaccurate predictions because paging, and access to memorymapped files, are not modelled. This paper extends tracing to handle such workloads. At trace capture time, t...

In this paper, we re-visit the problem of unconditionally secure multiparty set intersection in information theoretic model. Li et.al [24] have proposed a protocol for n-party set intersection problem, which provides unconditional security when t < n 3 players are corrupted by an active adversary having unbounded computing power. Moreover, they have claimed that their protocol takes six rounds ...

In the technical literature, many random key pre-distribution techniques have been proposed to secure wireless sensor networks (WSNs). Such techniques only establish keys for some pairs of physically connected sensors. On the contrary, in many WSN applications, a source node must securely communicate with all of its neighbours. In this work, we address the issue of delivering secret link keys t...

As universities have entered a time of increased demand for public outreach and measurable impact, the universities are also exploring social media for student recruitment and science communication. Because many of the popular social media sites are free to use they could provide more democratic channels for organizational communication and marketing efforts. This research in progress investiga...

We propose and analyze a new shadowing field model meant to capture spatial correlations. The interference field associated with this new model is compared to that of the widely used independent shadowing model. Independent shadowing over links is adopted because of the resulting closed forms for performance metrics, and in spite of the well-known fact that the shadowing fields of networks are ...
