چکیده
The Scanner-Display system, called SCAD, is a device for communicating between computers and pictures. In its present form it can accept transparencies, measure the transmission at various points on the transparency, and convert this to a digital number. It can also accept digital data and produce pictures from it. The device is a transducer between digital computers and pictures. SCAD can be operated with digital tape or with a computer. When SCAD is operated with tape, it can either scan transparencies and write the digital information on a magnetic tape, or it can read a digital magnetic tape and display the data from it on a CRT. The display can be viewed and photographed. When SCAD is operated by a digital computer, the computer can either interrogate the transmittance of a transparency at points chosen by the computer, or it can display information, again with brightness and coordinates chosen by computer. The scanner can measure color, as well as brightness. SCAD measures brightness and displays data over a raster of discrete points. The raster may contain 1024 points along each of two orthogonal dimensions, although fewer points than this may be used. The resolution of the scanner and display depends on the components used in these units, and may be more or less fine than the spacing of the

Investigating the Cognitive Theories of Career Development
Objective: There are several theories proposed on the career development and researchers have classified these theories in different categories. Career-related cognitive theory is one of the latest categories including two theories: social cognitive theory of career development and cognitive information processing. The current study seeks to compare these two cognitive theories of career develo...
متن کاملXxvi. Cognitive Information Processing Academic and Research Staff A. Computer Models of Shift-variant Image- Processing Systems
The primary interests of the Cognitive Information Processing Group are related to gaining an understanding of visual processes; in particular, to the ways by which humans can process pictorial information. Thus we do research on electronic methods for simplifying pictures (still or motion), without altering significantly human subjective judgments of picture quality, on methods for altering pi...
