This paper presents a new power management technique aimed at increasing the energy efficiency of client-server multimedia applications running on wireless portable devices. We focus on reducing the energy consumption of the wireless network interface of the client by allowing the remote server to control the power configuration of the network card depending on the workload. In particular, we e...

Since the context plays a significant role in ubiquitous computing environment, many researches have studied about context-awareness system to improve the performance. An efficient learning mechanism is in importance of context-aware system, but there are seldom algorithms focused on convenience of systems by elaborating the learning mechanism with user's context information. As one of the most...

Cardiopulmonary bypass (CPB) allows operations on the heart in a motionless and bloodless field while reducing cardiac workload and sustaining systemic and coronary perfusion. Failure to wean from CPB remains a significant problem. Results from recent large registry data have shown dramatic improvement in the survival following ventricular assistance for post cardiotomy failure if instituted ea...

This paper describes the system design of a lowpower wireless camera. A system level approach is used to reduce energy dissipation and maximize battery lifetime. System properties such as the network configuration and data statistics are exploited to minimize computational switching. Embedded power supplies systems are also used to minimize energy dissipation under varying temperature, process ...

Process simulations are more and more time consuming. One of the methods that allow reducing the computational time of an application is to distribute the workload onto several computers. In this paper, we present some techniques from parallel and distributed computing applied to CAPE-OPEN compliant dynamic process simulations. We have implemented a fully transparent easy-to-use prototype which...

The existing SSL (Secure Socket Layer) protocol which mobile database system is using has many drawbacks, such as large amount of communication, computational complexity of encryption algorithm and the workload imbalance. In order to solve these problems, the paper proposes an improved SSL protocol. It decomposes the private key into independent elements which reducing the computational complex...

With unmanned aerial vehicles (UAVs), 36 licensed pilots flew both single-UAV and dual-UAV simulated military missions. Pilots were required to navigate each UAV through a series of mission legs in one of the following three conditions: a baseline condition, an auditory autoalert condition, and an autopilot condition. Pilots were responsible for (a) mission completion, (b) target search, and (c...

The objective of the study was to develop and evaluate a 2-day burnout intervention program focused at enhancing coping with stresses observed in teachers' work. Karasek's job stress model was used as the theoretical framework. The aim of the intervention was to teach participants to deal better with high job demands and low job control. Some cognitive-behavioural methods of overcoming workload...

Implementation of electronic health records (EHRs) impacts provider workflow at the point-of-care. Information access and data entry tasks have been appended to provider workload, adversely affecting clinical workflow as well as provider cognitive resources and job satisfaction. The quantity and complexity of information required for patient care and the documentation required for administrativ...
