Анализ переменных режимов вертикального смешивающего подогревателя

Проведен анализ работы вертикального смешивающего подогревателя в переменных установившихся режимах при изменении давления пара в корпусе; расхода и температуры воды на входе в подогреватель и относительной величины отводимого выпара. Показано, что основные изменения температуры нагреваемой воды в подогревателе при работе в переменном режиме происходят в первом отсеке

Change prediction for low complexity combined beamforming and acoustic echo cancellation

Time-variant beamforming (BF) and acoustic echo cancellation (AEC) are two techniques that are frequently employed for improving the quality of hands-free speech communication. However, the combined application of both is quite challenging as it either introduces high computational complexity or insufficient tracking. We propose a new method to improve the performance of the low-complexity beamformer first (BF-first) structure, which we call change prediction(ChaP). ChaP gathers information on several BF changes to predict the effective impulse response seen by the AEC after the next BF change. To account for uncertain data and convergence states in the predictions, reliability measures are introduced to improve ChaP in realistic scenarios

The role of action representations in thematic object relations

A number of studies have explored the role of associative/event-based (thematic) and categorical (taxonomic) relations in the organization of object representations. Recent evidence suggests that thematic information may be particularly important in determining relationships between manipulable artifacts. However, although sensorimotor information is on many accounts an important component of manipulable artifact representations, little is known about the role that action may play during the processing of semantic relationships (particularly thematic relationships) between multiple objects. In this study, we assessed healthy and left hemisphere stroke participants to explore three questions relevant to object relationship processing. First, we assessed whether participants tended to favor thematic relations including action (Th+A, e.g., wine bottle—corkscrew), thematic relationships without action (Th-A, e.g., wine bottle—cheese), or taxonomic relationships (Tax, e.g., wine bottle—water bottle) when choosing between them in an association judgment task with manipulable artifacts. Second, we assessed whether the underlying constructs of event relatedness, action relatedness, and categorical relatedness determined the choices that participants made. Third, we assessed the hypothesis that degraded action knowledge and/or damage to temporo-parietal cortex, a region of the brain associated with the representation of action knowledge, would reduce the influence of action on the choice task. Experiment 1 showed that explicit ratings of event, action, and categorical relatedness were differentially predictive of healthy participants' choices, with action relatedness determining choices between Th+A and Th-A associations above and beyond event and categorical ratings. Experiment 2 focused more specifically on these Th+A vs. Th-A choices and demonstrated that participants with left temporo-parietal lesions, a brain region known to be involved in sensorimotor processing, were less likely than controls and tended to be less likely than patients with lesions sparing that region to use action relatedness in determining their choices. These data indicate that action knowledge plays a critical role in processing of thematic relations for manipulable artifacts

Agroecological condition of land in tomsk region and prospects of application of methods of remote sensing

On base of studying the satellite images data received and processed at the space monitoring Center, Tomsk state University of control systems and Radioelectronics, and the results of ground agroenvironmental monitoring of arable land in Tomsk region performed by Federal state budgetary institution "Agrochemical service Station "Tomsk", revealed 39% of unused arable land, overgrown forest. From these investigations was find that the land used in agricultural production according to agro-chemical service, a decrease in soil fertility: decrease in organic matter content from 5 to 21%, increase in the proportion of acidic soils by 10 - 30%. The analysis of the main causes of negative trends in land use in Tomsk region was performed. The organizational and agro technical measures that increase the efficiency of use of arable land were developed. At the present stage is also required adaptation in the monitoring of agricultural land methods of Earth remote sensing, taking into account local soil and vegetation, and climatic conditions. There is a problem of integration of data with local ground measurements (and aircrafts) in order to bring them to a common spatial and temporal grid of satellite measurements, to construct dynamic models of seasonal cycles used to evaluate the observed changes of satellite data

Intelligent agents for matching information providers and consumers on the World-Wide-Web

In this paper, we discuss the various issues in designing intelligent software systems to assist world-wide-web users in locating relevant information. We identify a number of key components in such intelligent systems. These include a web document database management system, a client-based goal-directed search engine, an intelligent learning agent which discovers users' topics of interest by studying their browsing behavior, and an intelligent agent which monitors `hot' web sites. We give examples and suggestions on how these components are designed and implemented. We also describe the architecture of a prototype system that integrates the various components.published_or_final_versio

The Mother with the Button Eyes: An Exploration of the Story Construct of the ‘Other-Mother’

Neil Gaiman's (2002) children's novel, 'Coraline', which has recently been made into a stop motion movie, introduces its readers to a truly frightening figure: the Other-mother. This Other-mother comes out of a long tradition of stories in which the villain is a mother (or grandmother) figure, starting with the evil stepmothers so prevalent in fairy tales, and continuing in recent books such as Pullman's 'His Dark Materials' series in which the protagonist's mother is a major villain for most of the story. Gaiman drew this character partially from an obscure 19th century story by Lucy Clifford called 'The New Mother', in which a pair of naughty children lose their kind, loving mother, who is replaced by a monstrous one with glass eyes and a wooden tail. In this paper I will examine the parallels between Clifford's 'New Mother' and Gaiman's 'OtherGmother'. I also consider briefly another example of this nightmare mother in 'Ginny' in order to explain the pervasive and persistent presence of this figure in children's stories

Magnetic and Crystal Structural Investigation of Four Heusler Alloys in the FeCr Family

Heusler compounds have recently been under investigation by the materials science community due to their potential for applications in spintronic devices while being able to boast high Curie temperatures well above room temperature. Another aspect of Heusler alloys is that they have the capability of being half metallic. This means that their majority-spin electronic band structure is a usual metallic one, while the minority band is semiconducting with a gap at the Fermi level. This research focuses on the synthesis and analysis of four Heusler compounds in the FeCr family: FeCrV0.5Co0.5Al, FeCrMnAl, FeCrV0.5Mn0.5Al, and FeCrV0.75Mn0.25Al. After synthesis, all of these samples were provided with heat treatment before having x-ray diffraction (XRD) and magnetic measurements taken. FeCrV0.5Co0.5Al was discovered to be single phase and cubic in structure, with B2 type disorder, while showing paramagnetic behaviors. The remaining three compounds, FeCrMnAl, FeCrV0.5Mn0.5Al, and FeCrV0.75Mn0.25Al, were all shown to pertain a cubic structure with A2-type disorder as well as paramagnetic behavior with weak magnetism
