An algorithm is proposed that uses a broadside phased array to profile any number of arbitrary targets as a function of bearing. The technique places no restriction on either the number or location of the array elements.<> 相似文献

This paper presents a language based on the logic programming paradigm that supports objects, messages and inheritance. The object-oriented extension is fairly simple: objects are clusters of processes, objects' state is represented by logical variables, message-passing communication between objects is performed via multi-head clauses, and inheritance is mapped into clause union. The language implementation is obtained by translating logic objects into a concurrent logic language based on multi-head clauses, taking advantage of its distributed implementation on a massively parallel architecture. The runtime support realizes some interesting features such as intensional messages and the transparency of object allocation, object migration and parallelism. 相似文献

The authors report a case of acute abdomen in the third trimester of pregnancy as observed at the II Obstetrics and Gynecologic Department of Florence University. Emphasis is laid on the frequent abnormality of the symptomatology and therefore the difficult of early diagnosis. The conclusion is reached that a greater semeiologic accuracy on behalf of the specialist as well as memorization of the several clinical charts responsible for such pathology, allow an earlier diagnosis with consequent improvement of maternal and fetal prognosis. 相似文献

ABSTRACT: Vitamin E, thiamin, riboflavin, niacin, vitamin B6, and vitamin B12 concentrations of flat iron steaks and petite tenders from steers fed finishing rations containing 0% and 40% corn wet distiller's grains and solubles (WDGS) with and without supplemental vitamin E were determined. Feeding treatment groups were: 0% WDGS with basal vitamin E, 0% WDGS with supplemental vitamin E (500 IU daily), 40% WDGS with basal vitamin E, and 40% WDGS and supplemental vitamin E. Cattle can be fed 40% WDGS diets more economically than corn diets. The incorporation of 40% WDGS, with and without vitamin E, was hypothesized to have little effect on the vitamin concentrations of these value meat cuts. Flat iron steaks and petite tenders were broiled and/or grilled to 70 °C internal temperature. Mean cooking yields ranged from 68.7% to 78.2%. The majority of the vitamin concentrations of broiled and of grilled meat were significantly different (P < 0.05) from that of raw meat. Vitamin E concentrations of raw and cooked meat from steers that received supplemental vitamin E were significantly higher (P < 0.05) than those fed basal vitamin E. Significant differences in thiamin, riboflavin, vitamin B6, and vitamin B12 concentrations in raw flat iron steaks and in vitamin B6 in raw petite tenders were observed by WDGS. Thiamin, vitamin B6, and vitamin B12 concentrations of broiled flat iron steaks were significantly different (P < 0.05) than grilled. A few differences in vitamin concentrations of the flat iron steaks and petite tenders were observed by WDGS, vitamin E supplementation, and cooking treatments, but most of the vitamin concentrations were statistically similar. 相似文献

A study of the optical properties of poly(9,9‐dioctylfluorene‐co‐bithiophene) (F8T2) is reported, identifying this polymer as one that possesses a desirable combination of charge transport and light emission properties. The optical and morphological properties of a series of polymer blends with F8T2 dispersed in poly(9,9‐dioctylfluorene) (PFO) are described and almost pure‐green emission from light emitting diodes (LEDs) based thereon is demonstrated. High luminance green electroluminescence from LEDs using only a thin film of F8T2 for emission is also reported. The latter demonstration for a polymer previously primarily of interest for effective charge transport constitutes an important step in the development of emissive materials for applications where a union of efficient light emission and effective charge transport is required. 相似文献

4-Chloro-N-(pyridin-2-ylmethyl)aniline (CPYA) was synthesized by a simple and inexpensive method and tested as a corrosion inhibitor in acid medium for mild steel by using gravimetric studies and electrochemical measurements. An average maximum efficiency of 96.0% was achieved at 4.59 mmol/L. Corrosion kinetic and thermodynamic parameters were also analyzed. Surface analyses (atomic force microscopy and scanning electron microscopy) show that protection is enabled by adsorption on the metal, forming a film. Quantum chemical calculations were performed to access information regarding the molecular structure in the corrosive medium and to support interpretation of the results obtained by experimental methods. 相似文献
