This paper studies the bit error rate (BER) performance of an adaptive decode-and-forward (DF) relaying scheme for a cooperative wireless network operating on independent and identically distributed (i.i.d.) or independent and non-identically distributed (i.n.d.) Rayleigh fading channels. The considered network is with one source, K relays, and one destination in which binary frequency-shift ke...

Today there is widespread interest in using o -the-shelf computers to build economical supercomputers. Clusters such as Beowulf can use packages such as MPI to run coarsegrain parallel code. While this usually works well for applications with regular control structures and data distributions, it is not so e ective for many irregular applications. For such problems, ne-grain parallel programs ex...

We have developed an optical model for light collection in the TileCal geometry using bench measurement made on the individual components (clear and waveshift-ing bers, old and new production tiles) taking into account the features of the tower-by-tower readout geometry. The results of this model are in fair agreement with the light yield measured for muons at 90 taken in the May 1995 testbeam....

This paper investigates the powerplay in one-day cricket. The rules concerning the powerplay have been tinkered with over the years, and therefore the primary motivation of the paper is the assessment of the impact of the powerplay with respect to scoring. The form of the analysis takes a “what if” approach where powerplay outcomes are substituted with what might have happened had there been no...

Birefringence of oxide glass bers drawn from glass melts through an ori ce has been detected previously [1, 2]. This birefringence is a measure of anisotropy in glass structure that can in uence ber performance properties. Birefringence is produced during ber drawing as the ber is rapidly stretched in the viscoelastic glass transition range. The birefringence is \frozen" into the glass during r...

High-quality measurement is a necessary requirement to develop and evaluate the effectiveness of programs that use strength-based principles and strategies. Using independent cross-validation samples, we report two studies that explored the construct validity of the BERS-2 Youth Report, a popular measure designed to assess youth strengths, whose conceptual structure has not yet been examined. I...

ACL (Anterior Cruciate Ligament) has a fundamental role in knee biomechanics and ACL insuuciency is probably the most common knee pathology. Although widely investigated, ACL mathematical models are still controversial in simulations of knee kinematics. We have developed a new ACL model, made of 9 curvilinear independent bers, corresponding to the individual surface bers, which are described as...
