Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...

Laminar natural convection from an array of horizontal isothermal cylinders confined between two vertical walls, at low Rayleigh numbers, is investigated by theoretical and numerical methods. The height of the walls is kept constant, however, number of the cylinders and their spacing, the distance between the walls and Rayleigh number have been varied. The optimal spacing (confining walls) and ...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

We report new high resolution measurements of the elemental and isotopic composition of galactic cosmic ray B, C, N, and 0 nuclei with ~ 30 to ~ 130 MeV nucleon-•. These observations place limits on the isotopic composition of the cosmic ray source and restrict possible models of cosmic ray origin and propagation. In particular, we find that N is significantly depleted in the cosmic ray source ...

We propose a formalization of the COSMIC Full Function Point (COSMIC-FFP) measure for the Real-time Object Oriented Modeling (ROOM) language. COSMIC-FFP is a measure of functional size. It has been proposed by the COSMIC group as an adaptation of the function point measure for real-time systems. The COSMIC-FFP de nition is general and can be applied to any speci cation language. We propose a fo...

The Miniaturized Detector for Application in Space (MIDAS) is a compact device with dimensions 5 x 1 cm3 which combines position sensitive Si detectors and fast neutrons spectrometer. MIDAS developed purpose to act as linear energy transfer (LET) spectrometer the charged particles measure dose equivalent from both neutrons. It based on fully depleted monolithic active pixel sensors track deposi...
