The presence of coal in complex structures featuring sandstone reservoirs seriously hinders reservoir characterization and the identification fluids subsurface formations. Coal can strongly obscure reflections from sandstone, easily leading to false bright spots during exploration; thus, their boundaries cannot be accurately described. Furthermore, layers intercalated with thin seams form compo...

The definition of usability has evolved over time. Some of the proposed definitions have been general, and apply to all types of interactive systems. Others were tremendously influenced by the experience of those who proposed the definitions and the domain in which they practiced usability. The definitions, in general, seem to agree that the targeted users, the complexity of the task, the type ...

dust accumulation capacity of ficus carica l. and psidium guajava l. was investigated from eight different sites of multan, pakistan.  leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  maximum dust accumulation was occurred in the plants growing near road sites, while, min...

in what follows, the author has dealt with the relation between the necessary being as an unchangeable essence and his changeable and unchangeable attributes. neither is the ascription of any changeable attribute impossible for god nor is the ascription of any kind of unchangeable attribute possible. as the change of genitive attributes does not demand the change in the essence, it is possible ...

the relation between ethics and human good and evil attributes and his nature is among the age-old discourses in the field of practical philosophy (wisdom). since long ago, it has been of concern to the learned and the philosophers as to whether all ethics or a part of it in all human beings or in some of them is optional and acquired or non-optional, unacquirable, and unchangeable. this writin...

The creative cognition approach views creativity as the generation of novel and appropriate products through the application of basic cognitive processes to existing knowledge structures. It relies on converging evidence from anecdotal accounts of creativity and tightly controlled laboratory studies designed to examine the processes that are assumed to operate in those anecdotes. Specific examp...

Reservoir characterization has a leading role in the reservoir geophysics and reservoir management. Since the interests of the reservoir geophysics and reservoir managements are the elastic properties and reservoir properties of the subsurface rock for their purposes, a robust method is required for converting seismic data into elastic properties. Accordingly, by employing a rock physics model ...

It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

Wavelet estimation plays an important role in many seismic processes like impedance inversion, amplitude versus offset (AVO) and full waveform inversion (FWI). Statistical methods of wavelet estimation away from well control are a desirable tool to support seismic signal processing. One of these methods based on Homomorphic analysis has long intrigued as a potentially elegant solution to the wa...
