The growing demand for transportation tunnels in densely populated urban areas has led to the widespread adoption of twin tunnel configurations contemporary infrastructure projects. This research focuses on investigating complex interaction between soil, structures, and excavation tunnels. study employs boring machine (TBM) method utilizes two-dimensional numerical modeling based finite element...

In this paper, the authors examine UK mobile users’ perceptions of m-commerce utilization. For this purpose, the authors devise a Mobile Network Utilization Model empirically tested in experimental settings. The empirical findings reveal strong support for the capability of the proposed utilization model in measuring the concept of Mobile Task-Technology Fit (MTTF) and explaining the utilizatio...

OBJECTIVE The objective of our study was to evaluate the effect that knee flexion angle while femoral tunnels are being drilled may have on the length of these tunnels, in anatomical reconstruction of the anterior cruciate ligament. METHODS We measured the lengths of anteromedial and posterolateral tunnels for the anterior cruciate ligament in 20 unpaired anatomical knee specimens (10 right a...

Nowadays IPv6 over IPv4 tunnels are widely used to form the global IPv6 Internet. This paper analyzes a packet fragmentation problem in IPv6 over IPv4 tunnels due to the MTU difference between IPv6 and IPv4 layers, which would greatly degrade the performance of the tunnels if ever happened. It also demonstrates an ICMP based attack that could induce the problem and gives some advice on how to d...

The interaction mechanism between a two-lane shield tunnel and an existing during oblique underpass is matter of widespread concern in the engineering community, knowledge this area remains crude. In construction subway tunnels mountainous cities with huge topographical fluctuations, internal forces deformations are inevitable tunnels. To verify applicability technology empirical parameters to ...

The computational prediction of ligand entry and egress paths in proteins has become an emerging topic in computational biology due to the potential for estimating kinetic properties of drug binding. These properties are related to important pharmacological quantities such as the kon and koff rate of drugs [1,2].We have investigated the influence of protein flexibility on tunnel prediction usin...

Cavities are crucial for interactions of proteins with other molecules. While a variety of different cavity types exists, tunnels in particular play an important role, as they enable a ligand to deeply enter the active site of a protein where chemical reactions can undergo. Consequently, domain scientists are interested in understanding properties relevant for binding interactions inside molecu...

Seismic design loads for tunnels are characterized in terms of the deformations imposed on the structure by surrounding ground. The free-field ground deformations due to a seismic event are estimated, and the tunnel is designed to accommodate these deformations. Vertically propagating shear waves are the predominant form of earthquake loading that causes the ovaling deformations of circular tun...
