PADTUN - using semantic technologies in tunnel diagnosis and maintenance domain

Thakker, Dhaval, Dimitrova, V., Cohn, A.G., Valdes, J. January 2015 (has links)
Yes / A Decision Support System (DSS) in tunnelling domain deals with identifying pathologies based on disorders present in various tunnel portions and contextual factors affecting a tunnel. Another key area in diagnosing pathologies is to identify regions of interest (ROI). In practice, tunnel experts intuitively abstract regions of interest by selecting tunnel portions that are susceptible to the same types of pathologies with some distance approximation. This complex diagnosis process is often subjective and poorly scales across cases and transport structures. In this paper, we introduce PADTUN system, a working prototype of a DSS in tunnelling domain using semantic technologies. Ontologies are developed and used to capture tacit knowledge from tunnel experts. Tunnel inspection data are annotated with ontologies to take advantage of inferring capabilities offered by semantic technologies. In addition, an intelligent mechanism is developed to exploit abstraction and inference capabilities to identify ROI. PADTUN is developed in real-world settings offered by the NeTTUN EU Project and is applied in a tunnel diagnosis use case with Société Nationale des Chemins de Fer Français (SNCF), France. We show how the use of semantic technologies allows addressing the complex issues of pathology and ROI inferencing and matching experts’ expectations of decision support.

Používání pohádek a folklorních zvyků rodiči / Use of fairy tales and folk-lore habits by parents

Horková, Lenka January 2012 (has links)
The goal of this Diploma Thesis was to find out how parents are using the fairy tales stories and folklore traditions, especially in form of using the spooky supernatural beings. By using the available sources, we explored the actual psychological knowledge about the origin and meanings of fairy tales, the processes of their change during the time and anticipations about their usage nowadays. The psychoanalytic theory happens to be very useful in explaining the symbology and meaning of fairy tale. Freud's ideas were also applicable for explication of fear of supernatural beings. Empirical data, obtained by interviewing the families, brought the answers regarding the process of reading the fairy tales and haunting, a parental motivation to these activities, measure of parental understanding of fairy tales and explanations about the children perception of fairy tales and spooky entities too. Key words : meanings of the fairy tales, using of fairy tale, using of spooks as a parenting method

Investigations of stereo setup for Kinect

Manuylova, Ekaterina January 2012 (has links)
The main purpose of this work is to investigate the behavior of the recently released by Microsoft company the Kinect sensor, which contains the properties that go beyond ordinary cameras. Normally, in order to create a 3D reconstruction of the scene two cameras are required. Whereas, the Kinect device, due to the properties of the Infrared projector and sensor allows to create the same type of the reconstruction using only one device. However, the depth images, which are generated by the Infrared laser projector and monochrome sensor in Kinect can contain undefined values. Therefore, in addition to other investigations this project contains an idea how to improve the quality of the depth images. However, the base aim of this work is to perform a reconstruction of the scene based on the color images using pair of Kinects which will be compared with the results generated by using depth information from one Kinect. In addition, the report contains the information how to check that all the performed calculations were done correctly. All  the algorithms which were used in the project as well as the achieved results will be described and discussed in the separate chapters in the current report.

Nuteistųjų moterų, vartojančių psichoaktyviąsias medžiagas, psichosocialiniai ypatumai / Psychosociological peculiarity of incarcerated women influenced of psychotropic substances use

Vaičiulis, Ignas 16 August 2007 (has links)
Stebėjimais ir epidemiologiniais tyrimais pagrįsti duomenys liudija, kad priklausomybę sukeliančių medžiagų vartojimas - grėsmingas socialinis reiškinys. Visuomenėje daugėja socialinių, sveikatos, juridinių problemų, susijusių su alkoholio, tabako ir narkotikų vartojimu. Amerikos visuomenės sveikatos asociacija teigia, kad tabakas yra viena iš pagrindinių ankstyvų mirčių priežasčių bendrojoje populiacijoje ir lemia širdies-kraujagyslių ligas bei vėžinius susirgimus. Alkoholio vartojimas kenkia šeimai, darbui, gimdo socialines problemas, tokias kaip alkoholizmas, nelaimingi atsitikimai, kriminalinė elgsena, smurtas, žmogžudystės, savižudybės. Pasaulio sveikatos organizacijos duomenimis, apie 40-60 proc. visų mirčių dėl tyčinių ir netyčinių traumų priežastis - alkoholio vartojimas. Europoje vykstantys negatyvūs procesai mus pasiekia labai greitai. Dėl patogios geografinės padėties Lietuva tampa alkoholio ir kitų narkotikų tranzito šalimi. Auga narkotikų prieinamumas ir tiekimas, neteisėta jų pasiūla bei paklausa ir poreikis narkotikams. Kovai su tokio pobūdžio blogybėmis nebuvome pasirengę, laiku nepradėjome prevencinės veiklos. Iš kitos pusės – vykstančios greitos permainos šalies ekonomikoje, socialinėje sferoje ir žmonių gyvenime keičia visuomenės požiūrį į kai kuriuos reiškinius, tarp jų ir požiūrį į narkotinių medžiagų vartojimą. Sklando įvairūs mitai apie narkotikus bei jų poveikį žmogaus psichikai. Formuojasi savas jaunimo požiūris į narkotikus ir jų vartojimą...

The society is witnessing a rapid increase of social, legal and health problems caused by alcohol, tobacco and drug use. American social health association claims that tobacco is one of the major causes of death in the general population. The use of alcohol harms family and professional life, leads to social problems such as alcoholism, accidents, criminal behaviour, violence, murders, and suicides. M. Singer and other scientists (1995) analysed psycho-sociologic problems of imprisoned women. The majority of them (81 %) acknowledged having experienced physical and sexual coercion, 83 % having abused alcohol and drugs; 40 % of the women claimed that social security was not available for them. L. A. Teplis and a group of scientists (1996) found out that 52, 4 % of imprisoned women abuse drugs, 23,9 % are alcohol addicted, 13,7 % suffer from a deep depression. Scientist from Western Europe and the USA emphasize in their works that the prison environment is a factor of a serious risk that influences the start and the continuous use of psychoactive substances. The objective and the goals of this research are intended to prove or to reject the hypothesis that the environment of custodial establishments and other psycho-sociological influences the spread of drugs and other psychotropic substances as well as their use.

Interconversion of nickel hydroxides studied using dynamic electrochemical impedance

Aiyejuro, Victor Omoatokwe 27 August 2020 (has links)
The interconversion of α- and β-Ni(OH)₂ was studied using cyclic voltammetry and dynamic electrochemical impedance (dEIS). Holding experiments were done at 0.5 V, 0.6 V, 0.8 V and 1.0 V while subsequent cathodic holds were applied in selected experiments at -0.1, -0.2, -0.25 V. The number of thickness of Ni(OH)₂ formed increased with increasing anodic potential. After α-Ni(OH)₂ was formed (< 0.5 V), it was easily reduced by sweeping down to -0.15 V. However, sweeping further (> 0.5 V) resulted in its "irreversible" conversion to β-Ni(OH)₂. Since β-Ni(OH)₂ was not reduced by sweeping to -0.15 V, the current, capacitance and the conductance at the α-Ni(OH)₂ peak (at 0.2 V) decreased as a result. However, β-Ni(OH)₂ was shown to be reducible during potential holds at -0.2 V or lower. In contrast, holding at -0.1 V only resulted in partial reduction. Eventually, a link was established between the reduction of β-Ni(OH)₂ and hydrogen evolution. The relatively slow reduction of the β-Ni(OH)₂ to metallic nickel appears to inhibit the capacitance increase at -0.15 V which occurs when the potential is kept under 0.5 V. The retention of a low capacitance while β-Ni(OH)₂ persists suggests a blocking mechanism. A concerted adsorption-desorption step which generates adsorbed hydrogen prior to hydrogen evolution was proposed. An exponential increase in current and capacitance occurred during the potential hold at -0.2 V. The capacitance increase suggests a reversal of the blocking (low capacitance at -0.15 V) caused by the persistence of β-Ni(OH)₂. Additionally, the exponential current decay during the hold at -0.2 V was significantly slower than the conversion of α- to β-Ni(OH)₂ at 0.8 V. This further demonstrates the possibility of a slow step involving surface blocking during the reduction of β-Ni(OH)₂. These observations provide new information on the mechanism and kinetics of the interconversion of α-Ni(OH)₂ into β-Ni(OH)₂ and the interaction of the latter in the hydrogen evolution reaction. / Graduate
