We discuss the one-loop virtual-sparticle corrections to QCD jet cross sections at large ET and large dijet invariant masses, with reference to present Tevatron and future LHC collider experiments. We find characteristic peaks and dips in the sparticle threshold region, due to in
Predicting Shear Capacity of Panel Zone Using Neural Network and Genetic Algorithm
Investigating the behavior of the box-shaped column panel zone has been one of the major concerns of scientists in the field. In the American Institute of Steel Construction the shear capacity of I-shaped cross- sections with low column thickness is calculated. This paper determi
Initial–Final-State Interference in the Z line-shape
The uncertainty in the determination of the Z line-shape parameters coming from the precision of the calculation of the Initial-State Radiation and Initial–Final-State Interference is 2×10−4 for the total cross section σ0 had at the Z peak, 0.15 MeV for the Z mass MZ , and 0.1 Me
Cyberspace and post-industrial transformations: A cross-national analysis of Internet development
At century's end, a combination of telecommunications and computer technologies has resulted in the creation of the Internet, a global network of computers that has been growing at an exponential rate. Although the Internet/World Wide Web combination is widely hailed as a new, po
Composite Action during Construction of Steel Trapezoidal Box Girder Bridges (0-1898-2)
In steel trapezoidal box girder bridge systems, the U-shaped steel girder is designed to act compositely with the concrete deck to form a closed box for live loading. During the construction stage, however, the behavior is not well understood. The usual practice of assuming the s
Hydrodynamic Performance Improvement of Double-Row Floating Breakwaters by Changing the Cross-Sectional Geometry
This paper is presented to develop the hydrodynamic performance of double-row floating breakwater (FBW) by changing cross-sectional geometry in high wave periods. The ANSYS-AQWA software employed for present calculations, which a potential-based boundary element method (BEM). rec
Design Optimization ofFiber Reinforced Plastic Composite Shapes
A global approximation method to optimize material architecture and cross-sectional area of new fiber reinforced plastic (FRP) composite beams is presented. The sections considered are intended for applications in short-span bridges. The beams are subjected to transverse loading,
Excessive Long-Time Deflections of Prestressed Box Girders. I: Record-Span Bridge in Palau and Other Paradigms
The segmental prestressed concrete box girder of Koror-Babeldaob (KB) Bridge in Palau, which had a record span of 241 m (791 ft), presents a striking paradigm of serviceability loss because of excessive multidecade deflections. The data required for analysis have recently been re
Contributions to the design of precast concrete culverts with unusual cross sections
Abstract Culverts are structures used in road and railway infrastructure works such as underpasses. Among the several forms of cross-sections, rectangular one (box culvert) has been mostly employed. However, when installed at high embankments, this structure shows values bending
Analysis and design of pultruded FRP shapes under bending
A comprehensive approach for the analysis and design of pultruded FRP beams in bending is presented. It is shown that the material architecture of pultruded FRP shapes can be efficiently modeled as a layered system. Based on the information provided by the material producers, a d
