Seismic reflection coefficient parameter-theoretical and Practical approach
( Qatar University , 1994 , Article)In this study, the effect of porosity and pore filler on the reflection coefficient parameter (R), are well deduced and some mathematical expressions were developed. This leads to the establishment of new expression of (R) ... -
Seismic Resolvable Frequency Band For The Pre-Miocene Oil Targets Ras Budran, Gulf Of Suez, Egypt
( Qatar University , 1988 , Article)Seismic attenuation problem in Ras Budran area, Gulf of Suez was tackled by defining the resolvable frequency band. This band can transmit through the Miocene evaporitic cyclic section and hit pre-Miocene oil targets. This ... -
Seismic Risk Evaluation Based on Maximum Likelihood Technique Applied For the Red Sea Region
( Qatar University , 1993 , Article)An analysis of the seismic risk is carried out for the Red Sea region for the recorded earthquakes in the area between 1. January 1913 and 31 December 1982. The maximum likelihood method was applied to determine the hazard ... -
Selection Of Optimized Fuzzy Rules For Process Control Systems: Using Genetic Algorithms
( Qatar University , 1996 , Article)In this paper modeling, selection and optimization of fuzzy rules for multivariable feedback process control and decision making systems are developed and discussed. A general model for multivariable fuzzy rules is derived ... -
Selectivity Coefficient Of Wire Basket Traps For Tilapia Nilotica
( Qatar University , 1984 , Article)Most methods of estimating growth and mortality rates require samples representative of the population with respect to size of one or more age groups. There is no fishing gear that exhibits equal selectivity towards fish ... -
A Self-Organizing Multisensor Fusion Classification Algorithm
( Qatar University , 1996 , Article)A self-organizing multisensor fusion algorithm to classify the inputs (data or images) into classes (targets, backgrounds) is presented. The algorithm forms clusters and is trained without supervision. The clustering is ... -
