introduction: side weir structures are extensively used in hydraulic engineering, irrigation and environmental engineering, and it usually consists of a main weir and a lateral channel. side weirs are also used as an emergency structure. this structure is installed on one side or both sides of the main channel to divert the flow from the main channel to the side channel. lateral outflow takes p...

This paper's numerical study, which applies the finite volume approach and SIMPLE algorithm, aims to dynamically analyze airflow through a channel with Z-obstacles. Three distinct models were used place Z-barriers inside channel. According Demartini et al.'s model (2004) as depicted in example A from present analysis, first Z-barrier (fin) is attached top wall (heated) second (baffle) bottom (i...

The interfering source in a two-user Z-channel can use either singleuser (SU) codes or rate splitting (RS) based multi-user codes. The RS codes are known to achieve better sum-rate than the SU codes. However, if the individual user’s reliability requirements are considered in a two-user Z-channel, it is unknown whether the RS codes achieve better performance than SU codes. To this end, the dive...

Although the crucial role of Ca 2 1 influx in lymphocyte activation has been well documented, little is known about the properties or expression levels of Ca 2 1 channels in normal human T lymphocytes. The use of Na 1 as the permeant ion in divalent-free solution permitted Ca 2 1 release-activated Ca 2 1 (CRAC) channel activation, kinetic properties, and functional expression levels to be inves...

BACKGROUND Delayed cerebral vasospasm is the most common cause of mortality and severe neurological impairment in patients who survive subarachnoid hemorrhage. Despite improvements in the field of diagnostic imaging, options for prevention and medical treatment-primarily with the calcium channel antagonist nimodipine or hemodynamic manipulations-are insufficient. Previous studies have suggested...

The status of W and Z cross-section and width measurements from the CDF and D0 experiments is reviewed. Recent results that are discussed: the cross-section for Z production times the branching ratio to tau pairs, the rapidity and transverse momentum distributions of Z production in the electron channel, and the direct measurements of the W width and the Z invisible width; the latter from an an...

( X , Y , Z ) is an ensemble of independent random triples, each distributed according to some probability distribution p ( z , y, z) . Two legitimate users, PX having X and Py having Y , communicate in order to agree on a joint key while keeping it almost unknown to an eavesdropper Pz who knows Z . Communication is conducted over a noiseless channel according to a predetermined protocol. Pz he...

We address the problem of blind identification of multiple-input multiple-output (MIMO) channels, based only on second-order statistics. We complement the theoretical study of a previously introduced closed-form solution derived within a correlative coding framework. This consists in pre-filtering the stationary random data processes, in order to attain diversity in the respective spectral powe...
