In the congenitally blind, language processing involves visual areas. In the case of normal visual development however, it remains unclear whether later visual loss induces interactions between the language and visual areas. This study compared the resting-state functional connectivity (FC) of retinotopic and language areas in two unique groups of late visually deprived subjects: (1) blind indi...
Knowledge of the ground condition and its hazards can play an important role in the selection of support and suitable excavation method in underground structures. Water transport tunnel is one of the most important structures with regard to the goal of excavation, special conditions and limitations considered in the design and execution of them. Beheshtabad Water Conveyance Tunnel with 64930 me...
This paper presents the investigation of surface geology and subsurface engineering to analyze excavation method stand-up time DK99-DK100 Jakarta-Bandung high-speed railway Tunnel, Indonesia. Rock mass quality, tunnel method, determined using Geological Strength Index (GSI), Basic Quality (BQ) systems, converted Mass Rating (RMR) The Japan Society Civil Engineering (JSCE) for comparison. result...
nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. in some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. theref...
the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...
We present a simple microscopic model to show how fluctuating two-level systems in a Josephson junction tunnel barrier of thickness L can modify the potential energy of the barrier and produce critical current noise spectra. We find low frequency 1/f noise that goes as L5. Our values are in good agreement with recent experimental measurements of critical current noise in Al/AlOx/Al Josephson ju...
By using this service interface and communicating with Map-Resolvers and Map-Servers, LISP Ingress Tunnel Routers and Egress Tunnel Routers are not dependent on the details of mapping database systems, which facilitates experimentation with different database designs. Since these devices implement the "edge" of the LISP infrastructure, connect directly to LISP-capable Internet end sites, and co...
An increasing integration of nanoscale sensors is being observed in BioSensing and Biomimetic systems. Power consumption is deemed a major limiter as the complexity of integration increases. Supply voltage based scaling using CMOS is also a challenge due to increasing leakage currents. This work presents alternative devices – Interband Tunnel Field Effect Transistors (TFETs) and Split-Gate Quan...
Background and aims: Air pollution reduction is important in health being of people and environment. Applying of an effective and efficient strategy is key consideration in facing with environmental challenges of management and control of air pollution. Recently, the main effort of environmental researchers is finding low cost and effective methods to control of environmental pollutants. Po...
