Progress in designing and applying computing systems has out raced progress in evaluating their performance. In order to circumvent this trend, there should be a simultaneous development...

Toward associating slot names with meanings

Creator:: Shih, Tsun-dah
Abstract:: The paper describes research on the representation of knowledge. The goal is to develop a formalism which can be used for the testing of hypotheses on the nature of human understanding and as a foundation or artificial intelligence programs. The ideas expressed herein are implemented in a program which converses...

Single fault detection in combinational logic circuits

Creator:: Medhekar, Ranjana A.
Abstract:: The material in this paper is divided into the following four chapters for convenience. Chapter 1 explains, how the idea of fault testing changed from testing the machine instructions to testing the hardware in logic circuits. Chapters 2, 3 and 4 present the different approaches considered, namely: 1. Path sensitizing...

Lipid-protein interactions : autoxidation studies involving freeze-dried methyl linolenate-gelatin foams

Creator:: Wehr, H. Michael and Sinnhuber, Russell O.
Abstract:: Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...

Roles of microorganisms in the deterioriation of rockfish

Creator:: Lobben, J. C. and Lee, J. S.
Abstract:: Seven species of microorganisms indigenous to fish were inoculated into sterile fish muscle, obtained from Sebastodes alutus and Sebastalobus alascanus, and the production of total volatile acids (TVA) and total volatile bases (TVB) was determined during storage at 1 C. No production of TVA and TVB was noted in sterile...

The effect of irradiation with ultraviolet light on chlorinated hydrocarbon insecticides : a review

Creator:: Banks, Kenneth A.
Abstract:: Pesticide chemists have recognized since the 1940's that ultraviolet light was deleterious to the insecticidal properties of certain compounds. However, it has been only within the last 15 years that a number of photodecomposition products of the chlorinated hydrocarbon insecticides have been isolated and identified. The degradation of insecticides by...

Volatile compounds from thermally oxidized methyl oleate

Creator:: Withycombe, Donald A., Libbey, L. M., and Lindsay, R. C.
Abstract:: Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...

Heat-induced compounds in strawberries

Creator:: Sloan, Jerry L.
Abstract:: Dimethyl sulfide, acetaldehyde, isobutyraldehyde, furan, 2-furaldehyde, 2-acetyl furan, and ethyl furoate were produced when pureed strawberries were heated to 120° C. for 30 minutes. Shorter heating periods were sufficient to produce the first three compounds. With the exception of acetaldehyde, none of the heat-induced compounds were detected in unheated, pureed...

Critique : a prototype style critic for FORTRAN

Creator:: Luh, Shan
Abstract:: Programming style is important for program understanding in programming tasks such as maintenance. testing, and debugging. The goal of programming style is to improve the readability of the source program without adversely affecting its performance. Critique is a FORTRAN source program style critic which analyzes the source program and outputs...

Implementation of molecular collection theory

Creator:: Srinivasan, Vijay
Abstract:: Hayes, in his Naive Physics Manifesto, identified two alternate ontologies for reasoning about liquids, an ontology based on the notion of a contained substance and one based on the notion of a molecular collection. Qualitative Process theory, proposed by Forbus, lends itself easily to encoding the contained substance ontology. It...
