amplitudes of seismic waves decrease with distance according to anelastic properties of the earth and geometrical spreading. the attenuation of ground-motion amplitudes in the frequency domain is an important problem in engineering seismology. it is of particular practical interest in the regions such as zagros (iran). the zagros fold- thrust belt, as a part of alpine- himalayan orogenic belt i...

Soft storey building is popular due to the functional and aesthetic purpose, despite its weakness in resisting seismic excitation. Nonlinear Static (Pushover) Analysis (POA) is a time saving and simple assessment procedure prosposed in Eurocode 8 (EC8). However, its reliability in designing structure still remains a question. At the first stage, seismic performance of several building models us...

The city of Kolkata, the State Capital of West Bengal is jolted by earthquakes time and again from the tectonic regimes of the Central Himalaya, highly seismogenic Northeast India and the active tectonics of Bengal Basin which is a pericratonic tertiary basin on which the City is located. Earthquake disaster mitigation and management necessitates seismic hazard assessment for the generation of ...

A method to predict crystal structures of crystaline drugs by systematic searching for minimum-energy packings is outlined. It bases on the use of the observed space-group occurrence factors to postulate crystal symmetry. The search region is chosen within the fundamental unit of multi-dimensional crystal-structure parameter space, including the cell parameters and rigidbody mlecular parameters...

In this paper, we describe DATPLEX, an extensible design-aid tool for physical database design. DAT-PLEX adopts a layered approach where each layer improves over its input design; and is \extensible" in the sense that an additional layer can be \plugged" into the tool, or an existing layer can be removed from the tool. The current implementation comprises three layers that improve the logical s...

Decision augmentation theory (DAT) holds that humans integrate information obtained by anomalous cognition into the usual decision process. The result is that, to a statistical degree, such decisions are biased toward volitional outcomes. We introduce our model and show that the domain over which it is applicable is within a few standard deviations from chance. We contrast the theory's experime...

This work is on the influence of rotational component earthquake excitations to response steel structures. In most studies, seismic input being modeled only using translational ground acceleration, while one ignored. was due observation that had minimal effect low-rise buildings. Hence, accelerometers used would not measure it, leading a lack records. Nowadays, technology provides such instrume...

Squeeze-film damping and acceleration load are two major issues in the design of inertial micro-switches. In order to deeply and systematically study these two issues, this paper proposes a typical vertically-driven inertial micro-switch, wherein the air and electrode gaps were chosen to design the required damping ratio and threshold value, respectively. The switch was modeled by ANSYS Workben...

I described the tactile-stimulated startle response (TSR) of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana), and American toad (Bufo americanus) tadpoles. One purpose was to rank species in terms of maximum acceleration performance. Also, I tested whether anatomical indicators of performance potential were predictive of realized performance. TSRs were elicited in a laboratory setting, ...

We present tools that support the run-time execution of applications that mix software running on networks of workstations and reconfigurable hardware. We use JHDL to describe the reconfigurable hardware, and JavaPorts to handle the communications between nodes in the network. The heterogeneous resources are handled by interposing a communication layer between the application and the hardware. ...
