avo as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. method discussed in this paper, consists of three stages, including: direct modeling, inverse modeling and cross plot interpretation. by direct modeling we can clarify lithology or fluid dependent attributes. analysis performed using both p-p and p-sv attributes. inverse modeling deals w...

marital life is one of the most globalized institutes of human being, formed by two persons with different capacities and talents, different needs and interests, in a word different personalities. achieving an intact family apparently relies on marital life health and favorable relationship between couple. therefore, making couple’s life healthy will surely lead to positive effects. in present ...

ibn meymun and qazi saeid qomi both believe there is no likeness between god and his creatures; he is completely different from his creatures in all forms and sense. they also refute the view that god has any positive essential attribute and claim that god’s negative attributes are his true attributes since positive attributes of god imply polytheism. based on this, they contend two things: neg...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

seismic attributes are very useful in seismic data interpretation. one of these attributes is the coherency attribute. seismic coherency is a complex trace and a geometrical attribute that is applied to a 3d cube of seismic data. it is a measure of lateral changes in acoustic impedance caused by the variation in structure, stratigraphy, lithology, porosity, and the presence of hydrocarbons. whe...

seismic attribute is a quantitative measure of an interested seismic characteristic. there are several seismic attributes. in recent years, time-frequency (tf) attributes have been developed which to reach them, tf analyzing of seismic data is required. a high resolution tf representation (tfr) can yield more accurate tf attributes. there are several tfr methods including short-time fourier tra...
