Because of the complicated conditions, great deformation, high stress, multi-variables, high non-linearity, the algorithm for structure optimization and its application in tunnel engineering has just been at the right beginning. However, how to make optimized design of structure for tunnel section, reduce excavation and increase support is a very urgent task now. Artificial intelligence shows e...

Bone defects caused by femoral and tibial tunnel enlargement can pose a significant technical challenge when planning to perform revision anterior cruciate ligament reconstruction. A number of options have been described for managing osseous deficiencies, including the use of large autograft or allograft bone dowels to provide sufficient tunnel fill and subsequent structural support for revisio...

The Konjsko tunnel is an integral part of the Zagreb-Split-Dubrovnik highway, section Prgomet-Dugopolje. It consists of two tunnel tubes having 1326.0 and 1133.8 meters in length. The greatest overburden amounts to 150 m. This paper presents geotechnical measurement results and back numerical analyses. Back numerical analyses in combination with geotechnical measurements enable safer and more r...

Based on practical engineering, considering the characteristics of unsymmetrical loading, shallow burying, and weak surrounding rock tunnel, MIDAS finite element software is adopted to analyze influence effect deformation a temporary steel support when tunnel excavated by two-step center diaphragm method (CDM). The simulation results are compared with field monitoring results. It can be seen th...

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...

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...

The role of road-tunnel ventilation has changed during the last decades. While in former years tunnel ventilation was responsible for providing an acceptable environment for tunnel users passing through the tunnel during normal operation conditions [30], nowadays the support of rescue conditions during a fire is dominating. The introduction of the fire case into the ventilation design resulted ...

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...

Geologic uncertainty in underground construction often leads to design and construction conservatism and hence to inflated costs. This paper presents a general model for the probabilistic prediction of tunnel geology, as a basis for developing more effective tunnel design and construction decision support systems. The geologic conditions along the tunnel alignment are modeled by a set of geolog...
