The word microfiche comes from the French meaning file index card. Using microfiche is an efficient way to communicate information, save time, save money and solve many communications problems. The major benefits of microfiche are: reduced printing costs, quicker dissemination, faster retrieval, lower cost distribution, space saving, ease of…

Generalized computational subroutines can reduce programing repetitions and wasteful computer storage use. The most useful are those that are flexible enough to handle a wide variety of situations. Subroutines may have details open to change in order to blend into the main program. They may be built into the computer library or supplied by the…

The paper describes recent research investigating the relationship between speed with which individuals can execute basic cognitive processes and performance on tests of intelligence and mental ability. Results are discussed in terms of three properties of the working-memory system which limit the amount of information for simultaneous storing and…

Experiments with two distinct collections, using three levels of indexing exhaustively for both documents and requests, show that substantially the same performance is obtained for very different levels of document indexing, if suitable choices are made of request level. (6 references) (Author)

Because they look to the computer for automatic processing of verbal information, linguists have allied themselves with mathematicians. (10 references) (Author)

Describes the current status of developments concerning the regulation of information flow across national borders. Similarities and trends in various privacy laws from European countries are discussed, as are the business position on data protection and efforts to harmonize national laws. (SW)

Presents an overview of the impact of fiber optics on telecommunications and its application to information processing and library services, including information retrieval, news services, remote transmission of library services, and library networking. (RAA)

Presents a class of distortion controlled vector quantizers that are capable of compressing images so they comply with certain distortion requirements. Highlights include tree-structured vector quantizers; multiresolution vector quantization; error coding vector quantizer; error coding multiresolution algorithm; and Huffman coding of the quad-tree…

Lesioning studies are often used in cognitive neuroscience to make inferences about the architecture of cognition. Recently, computational models have been used to address some of the underlying assumptions-such as modularity and locality-often implicitly used when interpreting lesion data. In this article, we explore the ''functional…

Neurological research has discovered much about how the brain works, Dr. Willis writes, but educators need to be cautious when applying this research to teaching. Following a brief explanation of the three most important technological advances in brain research (Positron Emission Tomography, Functional Magnetic Resonance Imaging, and Quantitative…
