Despite the many axial confinement models already proposed for determination of peak compressive strength fiber-reinforced polymer (FRP) confined concrete columns, they are, in general, applicable only to columns circular or square cross-section, with full partial arrangements. In this study, by proposing a cross-sectional and confining system unification approach, new model is developed calibr...

In this article, a new CAD model for the coplanar waveguide (CPW) cross-over air-bridge is proposed. The model takes into account the CPW open-end capacitance and the vertical strips of the bridge. The section directly underneath the bridge is modeled as a small section of a microstrip line. Our results are in good agreement with the published full-wave results. © 2005 Wiley Periodicals, Inc.

Dust control is one of the most difficult challenges for underground coal mine operators, especially longwall operators. The widely used dust technologies at a section are ventilation air and water sprays, whereas continuous miner has added advantage having scrubber built into miner. To test potential benefits integrating flooded-bed shearer, authors designed system full-scale mock-up shearer. ...

In the context of Human-Robot interaction estimating gaze orientation brings useful information about human focus of attention. This is a contextual information : when you point something you usually look at it. Estimating gaze orientation requires head pose estimation. There are several techniques to estimate head pose from images, they are mainly based on training [3, 4] or on local face feat...

We study precise calculation of neutralino relic density in the minimal supergravity model. We compare the exact formula for the thermal average of the neutralino annihilation cross section times relative velocity with the expansion formula in terms of the temperature, including all the contributions to neutralino annihilation cross section analytically. We confirm that the expansion formula fa...

In this paper we consider a simultaneous system of spatially interrelated cross sectional equations. Our speci...cation incorporates spatial lags in the endogenous and exogenous variables. In modelling the disturbance process we allow for both spatial correlation as well as correlation across equations. The data set is taken to be a single cross section of observations. The model may be viewed ...

The study of top quark pair production at the Tevatron is now entering the realm of precision physics. With 2.8 fb−1 of CDF data there are over 1200 reconstructed tt̄ events in the lepton + jets channel. As the integrated luminosity increases, it is possible to improve not only measurements of the properties of the top quark but also maybe to search for new physics by comparing the tt̄ cross sect...

We study the effects of threshold resummation on the rapidity dependence of singleparticle-inclusive cross sections, using the prompt photon cross section as an example. We make use of the full resummation formula at next-to-leading logarithmic accuracy and develop a new technique for treating rapidity in resummation. We compare our phenomenological results with those of previous studies and di...
