This diploma thesis mainly deals with valuation of steel structures from the perspective of an investor. Today there are several types of steel constructions, which assemble is partly done in workshop, so called “bridge-workshop”, and the rest of the assembling is done directly at the building site. That is the main difference from the construction industry. This fact makes financial valuation of whole thesis very difficult, because construction companies often do not state detailed breakdown of their activities. The main goal of this thesis is to suggest procedure how to value steel constructions in a phase of documentation processing, workshop production, transportation and technological equipment construction at the site.

The aim of this thesis is to find the best option of the building technology for a house. The thesis is divided into two sections – theoretical and practical. The theoretical section consists of three parts. The first part deals with theory of costs and pricing. Second part specifies types of the budgeting used in Czech Republic and the last part is focused on description of the selected construction systems used for building a house. Second section deals with description and the layout of the house, for which three budgets are set with a respect to the used option of the construction system. Furthermore, a comparison of the technical parameters as well as the costs analysis according to the TSKP is made. Finally, the optimal variant is selected with respect to the price and technical properties.

The diploma thesis is focused on a detection and a laboratory control of hazardous substances’ leak into the environment. These hazardous substances are classified. Further, it aims to chemical laboratories of the fire-brigade of the Czech Republic, as well as which place they hold in the fire-brigade system, and it indicates their main duties. This diploma thesis contains a review of some essential types of devices and mediums, which are in terms of the fire-brigade of the Czech Republic usable to practice the detection, determination and assessment of the hazardous substances in various figures of the environment in terrain, i.e. filling of duties of the chemical survey. The output of this diploma thesis is simulation of leaks of the toluene diisocyanate using ALOHA software, TerEx software and Rozex Alarm software. Further on, the proposal of another methodical sheet focused on leak actions of the concrete hazardous industrial substance – toluene diisocyanate. This methodical sheet could therefore broaden pro tempore elaborated sheets for chlorine and ammonia.

Les erreurs récurrentes et systématiques dans les processus de décision stratégique sont fréquentes ; et les théories actuelles des organisations sont insuffisantes pour les expliquer. La « Behavioral Strategy » suggère de lier ces erreurs à la psychologie des décideurs, et notamment à leurs biais cognitifs. Toutefois, cette vision suppose de connecter le niveau d’analyse de l’individu et celui de l’organisation. Nous proposons pour ce faire un niveau « méso », la routine de choix stratégique (RCS), où interagissent la psychologie des décideurs et les décisions stratégiques. Après avoir distingué trois types de RCS, nous formulons des hypothèses d’intervention sur celles-ci visant à prévenir les erreurs stratégiques. Nous illustrons ces hypothèses par six cas pratiques, en testons certaines par une étude quantitative, et analysons les préférences qui conduisent les dirigeants à les adopter ou non. Nous concluons en discutant les implications théoriques et pratiques de notre démarche. / Many types of strategic decisions result in recurring, systematic errors. Extant theories of organizations are insufficient to account for this phenomenon. Behavioral Strategy suggests that an explanation may be found in the psychology of decision makers, and particularly in their cognitive biases. This, however, calls for a link between individual-level cognition and affects, and organization-level choices. We propose “Strategic Choice Routines” as a middle level of analysis to bridge this gap, and identify three broad types of Strategic Choice Routines.This leads us to formulate hypotheses on how Strategic Choice Routines can be modified to minimize strategic errors. We illustrate these hypotheses through case studies; test some of them quantitatively; and analyze preferences that drive their adoption by executives. Finally, we discuss theoretical and managerial implications.

Die „Liste der fachlichen Nachschlagewerke zu den Normdateien“ stellt mit ihren derzeit mehr als 1.800 Einträgen ein verbindliches Arbeitsinstrument für die tägliche Praxis in der kooperativen Normdatenpflege des deutschsprachigen Raumes, speziell für die Terminologiearbeit in der bibliothekarischen Sacherschließung, dar. In jedem Normdatensatz der Schlagwortnormdatei (SWD) werden für den Nachweis und die Begründung der Ansetzungs- und Verweisungsformen eines Deskriptors im Feld „Quelle“ Referenzwerke aus der so genannten Prioritätenliste (Rangfolge der Nachschlagewerke), darüber hinaus aus der gesamten NSW-Liste, festgehalten und normiert abgekürzt. Diese Liste erscheint – von der Deutschen Nationalbibliothek (DNB) regelmäßig aktualisiert – jährlich in gedruckter Form mit einem Änderungsdienst (Änderungen, Neuauflagen; Neuaufnahmen) und steht seit einigen Jahren auch elektronisch abrufbar bereit. Dennoch ist sie „in die Jahre“ gekommen. Eine verbesserte Form der NSW-Liste war daher ein langjähriges Desiderat. In dem Vortrag wird über die konzipierten Funktionalitäten, die datentechnische Realisierung, die praktische Verwendung, den aktuellen Entwicklungsstand und die potenzielle Weiterentwicklung des neuen NSW-Tools berichtet. Die Normdateiarbeit ist komplex und anspruchsvoll. Durch die praxisorientierte Aufbereitung in diesem Tool wird die Einhaltung der für alle Neuansetzungen verbindlichen Rangfolge ganz entscheidend erleichtert, was von Beginn an die Qualität jedes Normdatensatzes erhöht. Den größten Zeitgewinn in der täglichen Praxis bringt der sofortige Zugriff auf verlinkte Volltexte. - Angesichts des zunehmenden multilateralen Datentausches bei gleichzeitiger dramatischer Verknappung personeller Ressourcen trotz eines erheblichen Anstiegs des inhaltlich zu erschließenden Literaturaufkommens wird dies im Workflow des vor kurzem eingeführten Online-Redaktionsverfahrens (ONR) für Normdaten der wohl nachhaltigste Effekt von „NSW online“ sein und auch in der künftigen Gemeinsamen Normdatei (GND) bleiben.

Magister Psychologiae - MPsych / The aim of the present study was to determine whether it was possible to identify changes in levels of postpartum depression and maternal adjustment and attitude in primiparae before and after birth. It aimed, furthermore, at assessing certain risk factors that could provide an understanding of the etiological factors (causes, determinants) influencing postpartum levels of depression and maternal adjustment and attitude. The study focused on risk factors among married and unmarried primiparae (first time mothers), with a view to establishing vulnerability profiles of the respective groups. The specific risk factors that formed part of the investigation were social support, personality (neuroticism) and life events. All the subjects investigated were recruited from the Mitchells Plain Maternity and Obstetrics Unit. A sample of 70 subjects, in the third trimester of pregnancy, voluntarily participated in the first part of this study. Of these, 26 belonged to the married group and 44 belonged to the unmarried group. As a result of the attrition factor, 57 subjects constituted the final sample for analysis. The final sample comprised 20 married and 37 unmarried subjects. Subjects were followed up four to eight weeks postpartum. Results revealed that there were no significant changes in levels of depression between the married and unmarried groups, either before or after delivery. Of significance was that with the event of birth, the depression scores amongst women rated high in neuroticism decreased significantly. Married women with high social support satisfaction scores were found to have low depression scores. Similarly, married women who experienced fewer negative life events had lower levels of depression than did the unmarried women who experienced fewer negative life events. The maternal adjustment and attitude scores did not change before or after birth, except in the married group. The married group showed a significant increase in scores on the maternal adjustment and attitude scores after the birth of the child. Regarding personality (neuroticism), the high neuroticism scorers had significantly lower maternal adjustment and attitude than did the low neuroticism scorers. As was the case with social support and depression, married women with high social support had a higher maternal adjustment and attitude. A significant effect of negative life events on maternal adjustment and attitude was only found for the married women (after delivery) who experienced a low number of life events. A stepwise multiple regression analysis was performed, in order to yield a model in which the depression and maternal adjustment and attitude scores would be predicted by risk factors. The finding of this analysis for both depression and maternal attitude and adjustment was not significant. Social Identity theory was suggested as a possible interpretation of these results. Future research which views social identity as a factor in understanding postpartum depression and maternal adjustment and attitude has been proposed .

[pt] Na primeira parte desta tese, são desenvolvidos dois esquemas de detecção por listas para sistemas MIMO multiusuário. As técnicas propostas usam uma única transformação de redução de reticulado (LR) para modificar a matriz de canal entre os usuários e a estação base (BS). Após a transformação LR, um candidato confiável do sinal transmitido é obtido usando um detector de cancelamento sucessivo de interferências (SIC). No detector em múltiplos ramos com redução de reticulado e cancelamento sucessivo de interferências (MB-LR-SIC) proposto, um número fixo de diferentes ordenamentos para o detector SIC gera uma lista de possíveis candidatos para a informação transmitida. O melhor candidato é escolhido usando o critério maximum likelihood (ML). No detector por listas de tamanho variável (VLD) proposto, um algoritmo que decide se o candidato atual tem uma boa qualidade ou se é necessário continuar procurando por um candidato melhor nos ordenamentos restantes é utilizado. Os resultados numéricos mostram que os esquemas propostos têm um desempenho quase ótimo com uma complexidade computacional bem abaixo do detector ML. Um esquema de detecção e decodificação iterativa (IDD) baseado no algoritmo VLD é também desenvolvido, produzindo um desempenho próximo a um sistema mono usuário (SU) livre de interferências. Na segunda parte desta tese, uma técnica de detecção desacoplada de sinais (DSD) para sistemas MIMO massivo é proposta. Esta técnica permite que o sinal composto recebido na BS seja separado em sinais independentes, correspondentes a diferentes classes de usuários, viabilizando assim o uso dos procedimentos de detecção propostos na primeira parte desta tese em sistemas MIMO massivos. Um modelo de sinais para sistemas MIMO massivo com antenas centralizadas e/ou antenas distribuídas operando em redes heterogêneas de quinta geração é proposto. Uma análise baseada na soma das taxas e um estudo de custo computacional para DSD são apresentados. Os resultados numéricos ilustram o excelente compromisso desempenho versus complexidade obtido com a técnica DSD quando comparada com o esquema de detecção conjunta tradicional. / [en] In the first part of this thesis, we introduce two list detection schemes for the uplink scenario of multiuser multiple-input multiple-output (MUMIMO) systems. The proposed techniques employ a single lattice reduction (LR) transformation to modify the channel matrix between the users and the base station (BS). After the LR transformation, a reliable candidate for the transmitted signal vector, provided by successive interference cancellation (SIC) detection is obtained. In the proposed multi-branch lattice reduction SIC (MB-LR-SIC) detector, a fixed number of different orderings, generates a list of SIC detection candidates. The best candidate is chosen according to the maximum likelihood (ML) selection criterion. For the proposed variable list detection (VLD) scheme, an algorithm to decide if the current candidate has good quality or if it is necessary to further explore different orderings to improve the detection performance is employed. Simulation results indicate that the proposed schemes have a near-optimal performance while keeping its computational complexity well below that of the ML detector. An iterative detection and decoding (IDD) scheme based on the VLD algorithm is also developed, producing an excellent performance that approaches the single user (SU) scenario. In the second part of this thesis, a decoupled signal detection (DSD) technique which allows the separation of uplink signals, for each user class, at the base station (BS) for massive MIMO systems is proposed. The proposed DSD allows to implement the detection procedures proposed in the first part of this thesis in massive MIMO scenarios. A mathematical signal model for massive MIMO systems with centralized and distributed antennas in the future fifth generation (5G) heterogeneous cellular networks is also developed. A sum-rate analysis and a study of computational cost for DSD are also presented. Simulation results show excellent performance of the proposed DSD algorithm when combined with linear and SIC-based detectors.

ABSTRAKT  I mitt examensarbete vill jag utforska och skapa smarta lösningar som hjälper oss att leva och bo på ett mer aktivitetsbaserat sätt i framtiden. Ett boende där jag vill uppmuntra och förenkla för oss alla att bo på mindre yta och med fler flexibla platser och funktioner, både för miljöns skull men även för en mer solidarisk fördelning av den yta vi förfogar över idag.  Mindre boendeyta betyder även att allt vi fyller våra hem med behöver vara väl genomtänkta och funktionella. Så vad krävs då egentligen för att vi ska vilja släppa ifrån oss av vår yta? Och kan jag genom min design skapa en öppen och varm känsla på mindre yta utan att försaka estetik och bekvämlighet? Eller hur kan smarta lösningar få oss att välja att bo kvar i ett mindre boende även när vi blir fler i familjen, något som inte enbart gynnar miljön utan även den egna plånboken? De blir några av mina utgångspunkter i mitt utforskande. De metoder jag använder i min research är enkäter, intervjuer och egna observationer av min hemmiljö tillsammans med internetsökningar och texter om kompakta boenden, fällbara lösningar och minimalism.  Mina designbeslut tar jag med input från de svar jag får in och min målsättning är att ha minst en produktionsklar modell att visa upp vid Konstfacks vårutställning i maj 2021.

Waking up in a world where everyone carries a miniature supercomputer, interaction designers find themselves in their forerunners dreams. Faced with the reality of planetary-scale we have to confront the task of articulating approaches responsive this accidental ubiquity of computation. This thesis attempts such a formulation by defining computation as a strange material, a plasticity shaped equally by its technical properties and the mode of production by which is its continuously re-produced. The definition is applied through a methodology of excursions — participatory explorations into two seemingly disparate sites of computation, connected in they ways they manifest a labor of care. First, we visit the social infrastructures that constitute the Linux kernel, examining strangle entanglements of programming and care in the world's largest design process. This is followed by a tour into the thorny lands of artificial intelligence, situated in the smart replies of LinkedIn. Here, we investigate the fluctuating border between the artificial and the human with participants performing AI, formulating new Turing tests in the process. These excursions afford an understanding of computation as fundamentally re-produced through interaction, a strange kind of affective work the understanding of which is crucial if we ambition to disarm the critical accidents of our present future.
