numerous causes are reported for ulnar nerve compression at the wrist, known as guyon's tunnel syndrome. in the present article, a patient with guyon's tunnel syndrome during pregnancy concomitant with an anomaly of ulnar nerve is described. a 29-year-old iranian woman presented with clinical features of guyon's tunnel syndrome (pain and paresthesia in the fifth finger of the left hand and atro...

AIM The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR. MATERIAL AND METHODS Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literatur...

in this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in abaqus software and the modified colliding bodies optimization (mcbo) algorithm implemented in matlab environment. this approach is then employed to study the influence of variable geometrical and geo-mechan...

conclusion the anterior tarsal tunnel syndrome is a known disease. a high index of clinical suspicion is required while dealing with the chronic cases. a detailed history to rule out any traumatic event is necessary too. timely investigations and surgical release give dramatic relief. case presentation a 40 -year-old male patient was presented with the history of persistent pain along the dorsa...

How to make IPv4 users utilize IPv6 applications is a typical scenario of the IPv4/IPv6 inter-operation. Nowadays, Tunnel Broker and 6to4 tunnel mechanisms are the popular solutions for this problem. This paper proposes a multihoming based algorithm MI46 to integrate Tunnel Broker and 6to4 tunnel mechanism. It overcomes the shortcomings of both Tunnel Broker and the 6to4 tunnel mechanism to for...

A Vehicular Ad Hoc network (VANET) is an emerging technology among the scholars and vehicular industries in recent years. The wireless collision Avoidance (CA) system sends early message to drivers before they reach accident zone on the road. This paper proposed an analytical model for warning messages through collision avoidance (CA) system. Use the Dichotomized head way model, the Braking mod...

Enabling Internet to Vehicular multicast communication is fraught with challenges due to the heterogeneous nature of the two networks. While the conventional multicasting in the Internet relies on ”structured” multicast routing, it is not clear how robust can be such routing structure in vehicular networks. We study the robustness of the multicast routing structure in vehicular networks for dat...

This paper is concerned with the problem of vehicular platoon control in vehicular ad hoc networks subject to capacity limitation and random packet dropouts. By introducing binary sequences as the basis of network access scheduling and modeling random packet dropouts as independent Bernoulli processes, we derive a closedform methodology for vehicular platoon control. In particular, an interesti...

A vehicular ad hoc network (VANET) is a vehicular-wireless network enabling vehicle-to-vehicle (V2V) communications and vehicle to infrastructure (V2I) communications. VANET has been under the international spotlight because various applications can be developed by leveraging those wireless communications to avoid vehicular collisions or to save energies. Most of VANET applications have been de...

The emerging vehicular networks are expected to make everyday vehicular operation safer, greener, and more efficient, and pave the path to autonomous driving in the advent of the fifth generation (5G) cellular system. Machine learning, as a major branch of artificial intelligence, has been recently applied to wireless networks to provide a data-driven approach to solve traditionally challenging...
