Reinforcement sensitivity theory (RST) stipulates that individuals have a behavioral activation system (BAS) guiding approach (rewarding) behaviors (Gray, 1971, 1981), and behavioral inhibition system (BIS) guiding conflict resolution between approach and avoidance (punishment) behaviors (Gray & McNaughton, 2000). Posttraumatic stress disorder (PTSD) severity overall relates to both BIS (e.g., ...

Field theory, when viewed as a medium coupled to a thermal bath, gains a useful new parameter : the temperature T . At the upper end of the T axis (g small) Yang–Mills theory (i.e. QCD without quarks, i.e. gluon black–body radiation) becomes susceptible to perturbation theory. The corresponding diagrammatics, however, runs against some “barrier of calculability”. At order g for the pressure and...

Betrayal trauma theory (BTT) predicts that unawareness of abuse by someone on whom a victim is dependent may serve to protect a necessary relationship. Lindblom and Gray (2009) contribute to a growing line of BTT studies by measuring narrative detail in a sample of undergraduates who met Criterion A of the PTSD diagnosis and who rated the abuse as their most distressing trauma. Although many co...

This paper presents a new enhancement technique using the fuzzy set theory for low contrast and nonuniform illumination images. A new parameter called the contrast factor which will provide information on the difference among the gray-level values in the local neighborhood is proposed. The contrast factor is measured by both local and global information to ensure that the fine details of the de...

In order to study the electromagnetic compatibility of a power system, authors adopted an effective analysis software and proposed a new prediction method. First, simulated and analyzed the electromagnetic transient when switching the no-load bus in the 500kV substation by the ATP software and proved the simulation results were consistent with the actual results; Second, introduced the Gray pre...

Face recognition is an important _eld of pattern recognition. Rough set theory used to extract the face from an image, by computing object lower approximation array according to gray level value. Fisher's Linear Discriminant Analysis,(FLDA), was used for feature extraction and dimensionality reduction. In the proposed methods Object similarity ratio and Euclidean distance were used for classi_c...
