Ray-optical prediction of radio-wave propagation characteristics in tunnel environments-Part 1 : theory
A tunnel is modeled as congregates of walls, with the wall being approximated by uniform impedance surface. The aim is to get a solution for a canonical problem ...
An overview of red-light surveillance cameras in Singapore
Unmanned, red-light surveillance camera systems help to reduce accident counts at intersections.
Rate of convergence of some space decomposition methods for linear and nonlinear problems
Convergence of a space decomposition method is proved for a class of convex programming problems. A space decomposition refers to a method that decomposes a space into a sum of subspaces, which could be a domain decomposition ...
A charge-trapping-based technique to design low-voltage BiCMOS logic circuits
New BiCMOS logic circuits employing a charge trapping technique are presented. The circuits include an XOR gate and an adder. Submicrometer technologies are used in the simulation and the circuits’ performances ...
Ray-optical prediction of radio-wave propagation characteristics in tunnel environments-Part 2 : analysis and measurements
The uniform theory of diffraction (UTD) developed in Part 1 is used to predict narrow- and wide-band propagation characteristics in tunnels at 900- and 1800-MHz frequencies. Narrow-band propagation characteristics is shown ...
Failure analysis of bond pad metal peeling using FIB and AFM
Aluminum bond pads on semiconductor chips play an important role in chips functionality and reliability. Bond pad peeling during wire bonding process results in yield reduction. The failure mechanisms of the peeling must ...
On component groups of Jo(N) and degeneracy maps
For an integer M >1 and a prime p ≥ 5 not dividing M, we study the kernel of the degeneracy map ΦʳMp,p --˃ ΦMpʳ,p, where ΦMp,p and ΦMpʳ,p are the component groups of J0(Mp) and J0(Mpʳ), respectively. This is then ...
The molecular mechanism of B cell activation by toll-like receptor protein RP-105
The B cell–specific transmembrane protein RP-105 belongs to the family of Drosophila toll-like proteins which are likely to trigger innate immune responses in mice and man. Here we demonstrate that the ...
Spin versus boson baths in nonlinear spectroscopy
The third-order optical response function of a chromophore coupled to a bath consisting of noninteracting two-level systems (TLSs) undergoing stochastic jumps is calculated. The results can be applied to a broad class of ...
Transient conjugate free convection from a vertical flat plate in a porous medium subjected to a sudden change in surface heat flux
The paper presents a theoretical study using Kármán–Pohlhausen method for describing the transient heat exchange between the boundary-layer free convection and a vertical flat plate embedded in a porous medium. The unsteady ...
