background: stroke is the first cause of morbidity all around the world. entrapment neuropathies are a known complication of stroke. the objective of this study is to assess the frequency of subclinical carpal tunnel syndrome in the healthy and paretic hands of stroke patients. methods: the authors performed nerve conduction study in the first three days after admission in 39 stroke patients wi...

Fault, crushed zone, and other unfavorable geology may frequently appear in the construction of tunnels, so it is course necessary to study on dynamic properties tunnels crossing rock fracture zone. Taking tunnel faults as object, this paper discussed constitutive relation satisfied by structures researched loading features failure characteristics different faults. It shows that: (1) areas with...

Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

Ablation behaviors of laminated carbon fiber reinforced plastics (CFRP) subjected to intense continuous wave laser in the supersonic wind tunnel are investigated experimentally. Comparable ablation tests other environments, i.e., static air, nitrogen and open airflow, also carried out. Laser rate is significantly larger than those particular, at least twice that an tangential airflow condition....

This paper describes a research program that was conducted in two phases to study the behavior of a high modulus CFRP system for strengthening steel structures. The first phase of the research consisted of an experimental program and finite element analysis to study the bond characteristics of the system. The findings indicate that a reverse tapered plate end detail can effectively increase the...

This work presents an optical non-contact technique to evaluate the fatigue damage state of CFRP structures measuring the irregularity factor of the surface. This factor includes information about surface topology and can be measured easily on field, by techniques such as optical perfilometers. The surface irregularity factor has been correlated with stiffness degradation, which is a well-accep...

Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel ...
