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 ...

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...

Seismic data are used in petroleum exploration to define geologic features in the subsurface. Recent advancements in seismic exploration have examined the effect of fluid and rock properties on seismic attributes. These advancements may provide improved reservoir characterization using techniques examined here. This is accomplished two parts; first, a study of fluid properties and their effect ...

The seismic reflection characterizations of a thin layer are important for reservoir geophysics. However, discussions on the reflection for a thin layer are usually restricted to precritical angle incidence. In this work, an exact analytical solution is derived to model the reflection amplitude and amplitude variation with offset (AVO) responses of a single thin bed for arbitrary incident angle...

The question whether chemotherapy-induced autophagy is causative to the demise of the cells or a part of the survival mechanism activated during cellular distress is unclear. Others and we have previously demonstrated apoptosis-inducing capacity of N-(4-hydroxyphenyl)retinamide (4-HPR) in malignant glioma cells. We provide evidences of 4-HPR-induced autophagy at a lower concentration (5 microM)...
