Backend Framework And Software Approach To Compute Earthquake Parameters From Signals Recorded By Seismic Instrumentation System, Raman Attri Sep 2005

Backend Framework And Software Approach To Compute Earthquake Parameters From Signals Recorded By Seismic Instrumentation System, Raman Attri

Raman K. Attri

Computation of seismic parameters and its interpretation from the recorded earthquake signal is empowered by digital data acquisition systems. This enables seismologist to automatically compute all the relevant parameters. Futuristic applications require extensive software development to implement seismic prediction and forecasting models. While developing such models, software developer prefer to write their own in-house analysis & modeling software with complete control over the required computations and models. This paper presents simplified mathematical framework of the seismic events and back-end computational software logic & algorithm to provide a simple framework to software engineers develop customized seismic analysis & computation software.


Non-Contact Detection Techniques And Technologies For Detection Of Objects In Air, Under-Ground And Under-Water, Raman Attri Aug 2005

Non-Contact Detection Techniques And Technologies For Detection Of Objects In Air, Under-Ground And Under-Water, Raman Attri

Raman K. Attri

In this white paper, we will present review and compilation of various object detection techniques currently available in different scenarios and situations. Automatic Object detection in the air, beneath other materials, under water and under the earth surface as well as over the surface is one of the advanced sciences employing many principles of multiple engineering domains together. “See-through” methods – seeing beyond the visible objects, has been inherent desire of human being since the practice of science. Not only this, a craving to detect the objects without directly “seeing upon” them with naked eyes calls upon some automatic procedures …
