Plentiful studies are reported on the semi-rigid behavior of joints between open section H shaped beam and column, but researches focusing on the semi-rigid performance of joints between square/rectangular hollow section (SHS/RHS) column-to-H shaped beam is to lag a lot. Most studies shows that when the SHS/RHS column connecting the H beam without internal diaphragm, the joints behavior is semi...

Data taken by the SLD Collaboration at the Stanford Linear Collider on e+ e-> Z0 obtained with a polarized electron beam have enabled many incisive tests of the electroweak sector of the standard model to be performed. We discuss our recent determinations of sinθw, derived from the total cross section asymmetry, and the quark final state asymmetries, As, Ac, Ab and branching ratios, Rc and Rb. ...

We study the production and leptonic decay of charginos in collisions of polarized photon beams including the complete spin correlations. The photons can be generated by Compton backscattering of polarized laser pulses off a polarized electron beam. Since the production process is determined alone by the electromagnetic coupling of the charginos this process allows to study their decay dynamics...

We study the wave equation for a massive scalar field in three-dimensional AdS (anti de Sitter) and dS (de Sitter) spaces to find what is the difference and similarity between two spaces. Here the AdS space is provided by the BTZ black hole with J = 0. To investigate its event (cosmological) horizons, we compute the absorption cross section, quasinormal modes, and study the AdS(dS)/CFT correspo...

Steel corrosion of bars in concrete structures is a complex process which leads to the reduction of the cross-section bars and decreasing the resistance of the concrete and steel materials. In this study, reliability analysis of a reinforced concrete beam with corrosion defects under the distributed load was investigated using the enhanced Hasofer-Lind and Rackwitz-Fiessler (EHL-RF) method base...

A linear array radar can be operated as a multiple-input multiple-output (MIMO) radar or a directed beam radar. A MIMO radar transmits orthogonal waveforms on each array element, which can achieve virtual aperture extension. Compared to a directed beam radar, MIMO radar requires longer integration times to maintain the same energy on target. This results in narrower Doppler bins but increased r...

Since the earthquakes in Northridge and Kobe in 1994 and 1995, respectively, many investigations have been carried out towards improving the strength and ductility of steel beam to column pre- and post-Northridge connections. In order to achieve these objectives, recent researches are mainly focused on three principles: reducing the beam section to improve the beam ductility, adding different k...

Experiment E01-020 1 consisted of a measurement of the H(e, ep)n cross section over a broad kinematical phase space using the Hall A 2 high resolution spectrometer pair. In order to calibrate our kinematics and check our cross section normalization, we measured elastic scattering in H(e, ep) using a 15 cm liquid hydrogen target with the “cigar-tube” cell. The normalization check involves knowle...

The Spiral2 driver uses a slow chopper situated in the common section of the low energy beam transport line to change the beam intensity, to cut off the beam in case of critical loss and to avoid hitting the wheel structure of rotating targets. The device has to work up to 10 kV, 1 kHz repetition frequency rate and its design is based on standard power circuits, standard vacuum feed-through and...
