A Robust Algorithm in Sequentially Selecting Subset Time Series Systems Using Neural Networks

In this paper a numerically robust lattice-ladder learning algorithm is presented that sequentially selects the best specification of a subset time series system using neural networks. We have been able to extend the relevance of multilayered neural networks and so more effectively model a greater array of time series situations. We have recognized that many connections between nodes in layers are unnecessary and can be deleted. So we have introduced inhibitor arcs, reflecting inhibitive synapses. We also allow for connections between nodes in layers which have variable strengths at different points of time by introducing additionally excitatory arcs, reflecting excitatory synapses. The resolving of both time and order updating leads to optimal synaptic weight updating and allows for optimal dynamic node creation/deletion within the extended neural network. The paper presents two applications that demonstrate the usefulness of the process.     

Television Instruction in Child Psychology.

The October 1955 issue of the "American Psychologist" was devoted principally to educational television. The need for research on the effectiveness of television instruction in psychology was emphasized. This is a report of an attempt to assess the impact of a series of television programs in child psychology on an audience of parents and teachers in the Denver (Colorado) area.

A Digital Block-Processor for SSB-FDM Modulation and Demodulation

A new algorithm is proposed for the digital implementation of theM-channel SSB-frequency-division multiplexing (FDM) modulator and demodulator, which is computationally attractive and inherently insensitive to parameter quantization.     

Analysis of Feature-Scale Wear in Chemical Mechanical Polishing: Modeling and Experiments

An asperity-scale wear model was developed to predict feature-scale wear in chemical–mechanical polishing (CMP), and was compared to the measured evolution of a lithographically patterned feature during full-scale CMP tests. To conduct this study, a lithographic technique was used to pattern a set of raised square features into a Cu-coated silicon wafer. Two-dimensional contact profilometry was used to measure the topography of an isolated feature on each wafer both before polishing and at various intervals throughout the polishing process. In the wear modeling formulation, a pad deflection-based contact mechanics model was developed and combined with a particle-based wear model to predict the wear evolution of the sample during CMP. The predicted wear of the sample feature was found to agree well to experimental results.     

Comparative functionality of soy proteins used in commercial meat food products

The use of soy isolates, concentrates, and texturized flours in meat food products is discussed. Functional characteristics of soy products in relation to their market application are reviewed. Soy isolates find more limited usage in meat food systems (2%) than the concentrates and textured soy flours (8–12%). In weak meat systems containing large amounts of fat (30–45%), the concentrate emulsifier and isolate are more important than the texturized soy flour. In chopped meat systems with 18–25% fat, the textural properties of soy flour (extruded) are more important than the use of an isolate. However, combinations of concentrate emulsifier and texturized flour are used. The method of cooking, i.e. fresh, deep fat-fried, or char-broiled, will affect the usage of soy combinations. In comminuted cooked cured meat food mixes, soy concentrates, and textured flours currently are being used. Nutritional properties are improved by inclusion of available ingredients high in lysine and methionine. Functional measurements of textural properties have been completed using the Instron with a Lee Kramer cell. Both model emulsion systems and finished product results substantiate the accuracy of textural properties in soy-meat mixes using the Instron.     

An aversion-desensitization treatment for alcoholism.

Gave to 21 30-58 yr. old male alcoholic patient volunteers in a state hospital a mean of 11 hr. in 1 of 3 treatments: (a) interpersonal aversion (in which S watched his own audiovideo-recorded drinking "confessions" while being systematically derogated by 2 therapists), followed immediately by systematic desensitization to drinking-related anxieties; (b) interpersonal aversion, followed by a control procedure consisting of friendly interaction; or (c) group discussion. Ss were given the Alcadd Test and MacAndrews' Alcoholism scale (derived from the MMPI) before, after, and 6-9 mo. following treatment. Follow-up interview data show that 5 of the 7 traceable Ss given the interpersonal aversion-systematic desensitization treatment reported abstinence, compared with only 1 of 7 treated by the interpersonal aversion-control procedure. This significant difference was supported by changes on the Alcadd Test but not on the Alcoholism scale. Difficulties in contacting Ss for follow-up precluded complete comparisons with the group-discussion Ss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Number-related discrimination and summation by squirrel monkeys (Saimiri sciureus sciureus and S. boliviensus boliviensus) on the basis of the number of sides of polygons.

In Experiment 1, with the number of sides or angles of irregular polygons as cues, programmed training, and a 90% correct criterion (36 of 40), 2 squirrel monkeys' (Saimiri sciureus sciureus and S. boliviensus boliviensus) best performances were to discriminate heptagons from octagons, a 3rd's best was hexagons from heptagons, and a 4th's best was pentagons from heptagons. In Experiment 2, on most trials 2 polygons on one or both discriminanda had to be summed to determine which discriminandum had the total fewer sides. Only 1 monkey met criterion (27 of 30) on the 2 tasks, 6 vs. 8 and 7 vs. 8 sides, but the other 3 performed better than chance on the 6 vs. 8 task. We conclude that previous studies of animals' discrimination of polygons in terms of complexity were minimally relevant to this work, and counting and subitizing were rejected in favor of a prototype-matching process to explain our monkeys' performances.

The smoothed step-track antenna controller

The paper describes a new adaptive tracking system which, unlike simple step-track sytems, does not use the stepping cycles to directly position the antenna. The system can cope with severe noise; about 15 dB worse than step track. The system is cheap and practical. Results are given for both large and small dish antennas.
