General issues relating to the use of outcome and process data from the treatment of antisocial children to predict future childhood adjustment are examined. For outcome measures, it was assumed that variables based on direct observation of child behavior would provide a better predictor of long-term adjustment than would ratings by participant adults. Long-term adjustment measures consisted of police arrest and out-of-home placement data collected 2 years after treatment termination. Observation data collected at termination predicted future police arrest, but parent and teacher ratings did not. It was also hypothesized that measures of the processes thought to produce the changes in child antisocial behavior would serve as predictors of future adjustment. The data supported this hypothesis.

Fundamental frequency techniques are used to analyze the series-parallel resonant converter under heavy load conditions, both with a continuous, but distorted parallel capacitor voltage waveform, and with a discontinuous capacitor voltage waveform. The analysis is validated with results from an experimental prototype. The application of the technique to the parallel-loaded L-C resonant converter is also considered. 相似文献

Non-aqueous electrodeposition of ZnO and CdO films 总被引:1,自引:0,他引:1
ZnO films were electrodeposited from a dimethylsulfoxide bath containing dissolved gaseous oxygen. Variations in deposition parameters and their effects on the structural (crystal size, growth direction), optical (bandgap variations, photoluminescence) and electrical (conductivity) properties are described. The technique was extended to give highly-conducting films of CdO. 相似文献

We describe an apparatus and method for measurement of the sulfur concentration in the pulp stream under refinery conditions using neutron radiation analysis. We present the block diagram for the apparatus and the results of testing of the apparatus at the Novoyavorovo ore refinery.Translated from Izmeritel'naya Tekhnika, No. 2, pp. 60–61, February, 1995. 相似文献

A Skeleton-based Approach for Detection of Perceptually Salient Features on Polygonal Surfaces 总被引:1,自引:0,他引:1
The paper presents a skeleton‐based approach for robust detection of perceptually salient shape features. Given ashape approximated by a polygonal surface, its skeleton is extracted using a three‐dimensional Voronoi diagramtechnique proposed recently by Amenta et al. [ 3 ]. Shape creases, ridges and ravines, are detected as curvescorresponding to skeletal edges. Salient shape regions are extracted via skeleton decomposition into patches.The approach explores the singularity theory for ridge and ravine detection, combines several filtering methodsfor skeleton denoising and for selecting perceptually important ridges and ravines, and uses a topological analysisof the skeleton for detection of salient shape regions.

Density and carbon content are studied for their effect on strength (hardness) and magnetic (coercive force, saturation magnetization) properties of powder steels ZhGr1 and ZhGr1D3. It is shown that the hardness of articles made of these steels may be determined indirectly by measuring two magnetic characteristics.Physicotechnical Institute, Russian Academy of Sciences, Izhevsk.
