This study investigates the application of classification methods for the prognosis of future disability on MRI-detectable brain white matter lesions in subjects diagnosed with clinical isolated syndrome (CIS) of multiple sclerosis (MS). For this purpose, MS lesions and normal appearing white matter (NAWM) from 30 symptomatic untreated MS subjects, as well as normal white matter (NWM) from 20 h...

This paper proposes a tunnel window, a versatile three dimensional interaction technique, for both navigation and remote object manipulation in a large scale virtual environment. A tunnel window, which is created at an arbitrary position in space using a set of hand gesture commands, provides a secondary view whose viewpoint can be controlled independently from that of the primary view. A tunne...

IEEE 802.11 wireless networks have gained great popularity. However, handoff is always a critical issue in this area. In this paper, we propose a novel seamless handoff mechanism for IEEE 802.11 wireless networks which support IEEE 802.11i security standard. Our approach consists of a Dynamic Tunnel Establishing procedure and a seamless handoff mechanism. Dynamic Tunnel Establishing is for each...

Underground traffic tunnels serve as the entry and exit buildings for underground spaces. Most of ventilation air-conditioning systems in spaces rely on cooling or preheating to save energy. The temperature distribution has always attracted attention researchers. In this study, a heat transfer model tunnel was established based energy conservation boundary layer theory, field test carried out. ...

the aims of this study were about determining of amount of accuracy in tractor-moldboard plow system for tillage operation on paddies and also survey on efficacy of decision support software application on amount of energy use. for this purpose, decision support software was developed by visual basic 6.0. for survey in amount of efficacy of applying the decision support system on paddies tillag...

We introduce a new transistor architecture based on inter-band tunneling mechanism as a step towards exploring steep switching transistors for energy efficient logic applications. While there have been reports on tunnel transistors in Si, Ge material system and their alloys, we focus specifically on narrow gap compound semiconductor (CS) systems to develop tunnel transistors. We address the fol...

61 patients with clinically diagnosed and electromyographically confirmed carpal tunnel syndrome were enrolled in a prospective study to evaluate the effectiveness of a nerve supplement on pillar pain after carpal tunnel surgery. All of the patients underwent endoscopic carpal tunnel release. 15 of the patients also took the nerve support supplement NeuroGen as part of their perioperative treat...

Social support is the physical and emotional comfort given to someone in times of need or crises and it is especially important for maintaining good physical and mental health. Despite the contribution of intelligent technological devices, which have led to the availability of various types of social support systems, the latter are still not widely known to many. These support systems are curre...

The capabilities of the ventilation systems in the two road tunnels at Dartford (UK) are analysed using a multi-scale modelling approach. Both tunnels have complex semi-transverse ventilation systems with jet fans to control longitudinal flow. The construction and ventilation systems in the tunnels are described and the current emergency ventilation strategies are presented. The analysis includ...

NEtwork MObility Basic Support (NEMO BS) protocol has been investigated to provide Internet connectivity of a group of nodes, which is suitable for Intelligent Transportation Systems (ITS) applications. Since NEMO BS is based on Mobile IPv6 (MIPv6), it often increases traffic load and handover latency due to the handover procedure. Thus, schemes combining Proxy MIPv6 (PMIPv6) with NEMO (PNEMO) ...
