Work capacity and anticipation in A.A. Ukhtomsky’s concept of dominance

This paper presents the results of theoretical and experimental investigations of human activity and anticipation based on A.A. Ukhtomsky’s concept of brain dominance – a non-equilibrium system-forming factor in living systems. Facts on the stages of dominance formation are presented in relation to the creative abilities of the human brain and the role of fatigue as a “lever” for increasing systems’ work capacity on the basis of “trace exaltation”. Individually, specific features of dominantogenesis are compared with variations in behavioural types. On the basis of chronotopic EEG analysis, we delineate cortical dominants that underlie individual specifics of cognitive processes. The relation is shown between anticipation and the “expansion of dominants” – the broadening of “distal perception” in time and space, as framed by A.A. Ukhtomsky.

Remark on “on the capacity of a multiple-access vector adder channel” by A.A. Frolov and V.V. Zyablov

For vector adder channel, we present an upper bound on the capacity, which coincides with the lower bound given in [1]. Thus, we prove optimality of the uniform probability distribution of symbols for γ ∈ (0, γ*] and of the twisted distribution for γ ∈ (γ*,∞), where γ is the ratio of the number of users to the number of subchannels and γ* = 1.3382.

Abstract

The benefits for the consumer, and for the practising ergonomist of implementing a marketing strategy designed to increase consumer awareness of ergonomics is discussed with reference to the experiences of ICE Ergonomics, a commercial ergonomics research and consultancy organization based in Great Britain. The marketing strategy, which addresses the areas of publicity, education and practical involvement, forms one part of an integrated marketing strategy now being implemented by ICE.     

在辐射区内潜行 深入解析《S.T.A.L.K.E.R.Shadow of Chernobyl》

前苏联乌克兰地区，切尔诺贝利核电站，1986年4月26日凌晨1点23分。远方突然传来了爆炸声。顿时火光四起，这次的爆炸事故释放的辐射量，大约是二战时，美军在日本广岛原子弹爆炸能量的两百倍以上，核电站周围30公里内的区域均被划为隔离区。哪怕在二十年后的今天，因为核辐射引发的疾病、癌症，同样影响到很多人的生活……

Crop classification is a key issue for agricultural monitoring using remote-sensing techniques. Synthetic aperture radar (SAR) data are attractive for crop classification because of their all-weather, all-day imaging capability. The objective of this study is to investigate the capability of SAR data for crop classification in the North China Plain. Multi-temporal Envisat advanced synthetic aperture radar (ASAR) and TerraSAR data were acquired. A support vector machine (SVM) classifier was selected for the classification using different combinations of these SAR data and texture features. The results indicated that multi-configuration SAR data achieved satisfactory classification accuracy (best overall accuracy of 91.83%) in the North China Plain. ASAR performed slightly better than TerraSAR data acquired in the same time span for crop classification, while the combination of two frequencies of SAR data (C- and X-band) was better than the multi-temporal C-band data. Two temporal ASAR data acquired in late jointing and flowering periods achieved sufficient classification accuracy, and adding data to the early jointing period had little effect on improving classification accuracy. In addition, texture features of SAR data were also useful for improving classification accuracy. SAR data have considerable potential for agricultural monitoring and can become a suitable complementary data source to optical data.     

S.T.A.L.K.E.R.：迷失

说起FPS(第一人称射击)类游戏来，可能大多数玩家第一时间想到的就是去年炒得沸沸扬扬的《毁灭战士3》，以及今年E3刚刚露面的《半条命2》，这两款游戏都以极其出色的游戏画面赢得了众多玩家的青睐，同时也成为了当之无愧的“硬件杀手”。不过，在游戏制作领域历来就不缺乏挑战，
