The importance of emergency response system has grown significantly in recent times due to the frequent manmade and natural disasters such as September 2001 and Hurricane Sandy 2012. Disaster, manmade and natural, causes great economic and human losses each year throughout the world. Transportation and Telecommunication play a crucial role in disaster response and management. Our previous work ...

We investigate the sensitivity of AVO attributes to uncertainty in migration velocity in a synthetic dataset. The synthetic data was built using a earth model with typical rock properties from a real North Sea turbidite field. The model includes a thick overburden layer with complex velocity anomalies. We examine the sensitivity of AVO response due to the presence of this complex layer and quan...

The method of simultaneous PP-PS inversion has recently been developed and tested on the 3-D Blackfoot seismic data set. This paper shows the application of this method on 3C-2D seismic data from Pikes Peak oilfield. The inversion was accomplished with a newly installed inversion module in ProMAX. After careful prestack processing, five limitedoffset stacked sections for each of the vertical an...

Factors affecting vehicle occupancy measurement were examined with the aim of improving state vehicle occupancy monitoring programs. A comparison was conducted of five data sets looking at the effects on average vehicle occupancy (AVO) of time of day, day of week, road types, HOV lanes, locational differences, and traffic volume. It was found that AVO was higher in the afternoons, on Saturdays,...

A new fast pruning algorithm is proposed for computing the IV, lowest frequency components of a Iength-~V discrete cosine transform, where AVO is any integer less than or equal to N, and AV = 2“‘. The computational complexity of the developed algorithm is lower than any of the existing algorithms, resulting in significant time savings. In the special case that AVO = 2 “ Q , the required number ...

The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis and the study of amplitude-variation-with-offset (AVO) attributes are the most reliable tools for semi-quantitative study of gas hydrate and f...

In the Bulgarian Black Sea shelf, several gas fields have been discovered in Maastrichtian–Paleocene sediments to date. this study, amplitude versus offset analysis (AVO) was carried out, and extended elastic impedance (EEI) also used, predict fluid lithology properties. Thus, these special cases, AVO (or reflection angle) can significantly de-risk existing Paleocene prospects allow focus on Mi...

Database management technology is central to the development of the Virtual Observatory (VObs), since its eventual aim is that the worlds astronomical data collections should look like a single large distributed database. Relational database management systems (DBMS) are good at searching through large tabular datasets such as source catalogues, but the important operation of cross−matching sou...
