This diploma thesis deals with a design layout of the fan power supply that ensures the increase of the efficiency of the heating unit. For usage in the areas without electric power, the power supply is secured by thermoelectric generator. The system has to function on the basis of autonomous system which turns itself on only when necessary. In the introductory part of the paper there is a recherché of thermoelectric generators for general usage. Next it mentions the basic findings in from the field of DC/DC converters for low power applications. In this part attention is given to MPPT algorithm. Furthermore basic knowledge from the field of heat transmission together with its most used elements is described. Subsequently existing applications that increase the effectiveness of heating are mentioned. Their disadvantage however is that they depend on the external source of power supply. The practical part to a large extent covers the analysis of the suitability of the chosen thermoelectric module. For securing of the heat gradient of the generator there was a model created meeting the figures in the manual and there are several simulations in the MATLAB program. Furthermore several measurements of the thermoelectric module took place in order to secure realistic figures. Subsequently a DC/DC converter was chosen. Finally the testing was made on the real composition. In conclusion there is an overall evaluation including the real usage and the economical aspect of the project. The outcomes of the work enable to avoid common mistakes that are part of many specialized articles. The created system is to be used after the adjustment of the cooling to the required aim. At the same time it becomes very effective.

Thesis (MEng (Electrical Engineering)--Cape Peninsula University of Technology, 2019 / The purpose of an electrical power system is to supply electrical energy to the customers. Power transformers are required to transform the system voltage from generation to transmission and distribution levels. Protection and control systems must ensure that power system high voltage equipment such as transformers operate and deliver save, reliable and secure electricity supply. The aim of the project research work is to develop and implement a strategy, methods and algorithms for monitoring, protection and voltage control of parallel power transformers based on IEC 61850-9-2 process bus standard. NamPower is a power utility in Namibia. The IEC 61850 protocol for electrical substation automation system is used for the protection and control of 5 power transformers operated in parallel in an existing substation system. The IEC 61850-9-2 process bus standard is however not used in regards of Sampled Values (SV). Protection and control devices are connected to a substation communication network, routers and switches using fibre optic linked Ethernet. Inductive Current Transformers (CTs) and Voltage Transformers (VTs) secondary circuits are hardwired to Intelligent Electronic Devices (IEDs) and fibre optic links are not used for this purpose at process level communication. The research focuses on the implementation of the IEC 61850 standard with Merging Units (MUs) and sampled values to improve the existing implemented protection and control system at NamPower. This includes substation communication networks and MUs used for transformer protection, voltage regulator control and cooling fan control. At the present the CTs located at the transformer bushings and switchgear and the VTs located at the switchgear are hardwired to the inputs on protection and control IEDs. The research focuses on issues with the copper wires for voltage and currents signals and how these issues can be eliminated by using the MUs and the SV protocol. The MUs which are considered in this Thesis is to improve the voltage regulator control and the control of the cooling fan motors. The voltage regulator control IED is situated at the tap change motor drive of the On-Load Tap Changer (OLTC). The IED of each transformer is required to regulate the voltage level of the secondary side bus bar it is connected to. All the regulating IEDs are required to communicate with each other and collectively to control the bus bar voltage depending on the switching configuration of the parallel transformers. The control circuit for controlling the cooling fan motors is hardwired. Temperature analogue signal input into a programmable automation controller IED can be used for controlling the transformer cooling fans. A strategy, methods and algorithms for transformer protection, voltage regulator control and cooling fan motor control of parallel power transformers need to be developed and implemented based on IEC 61850-9-2 process bus. Power utilities and distributors can benefit from interpretation of the IEC 61850-9-2 standard and implementing MUs and SV in substations. MUs can be included in the power transformer protection, automation and control systems. A cost reduction in high voltage equipment, substation installation and commissioning costs and better performance of protection and control system are anticipated.

This master's thesis deals with the topic of emotionality of the Game of Thrones fandom in the era of convergence culture. Game of Thrones, which had been on air since 2011 to 2019, became a hit show which gained millions of supporters and each new season was highly anticipated among public. During the course of all eight seasons, the show caused numerous heated controversies. Final season left both viewers and critics torn. This master's thesis is therefore interested in detecting and describing emotions of the Game of Thrones fan community during the time that the final season had been on air. Apart from emotionality, emphasis is also put on the characteristics of the show and its fandom. Reasearch was carried out online via the method of participant observation in six comments sections on the fan website Watchers on the Wall.com. Insomuch as fandom is connected to convergence culture, media convergence and audience participation, these topics are also covered. The term fandom is defined and the difference between audience and fandom is described. Last but not least, terms such as collective intelligence and knowledge community, which are also associated with fandom, are defined as well. All findings and the answers to research questions are then presented in the summary.

Costume play (i.e. cosplay) is a performance of fandom rife with rituals and communication practices. Cosplay roleplaying performances are cultural practices that reveal how cosplayers interact with one another and among non-cosplaying members of their fandoms. This study examines the expectations that cosplayers hold for roleplay, the forms of roleplay, and the ways in which roleplay can become an instigator of harassment. Through the lens of Face-Negotiation Theory, the author discusses how roleplay functions to maintain or threaten the public images of cosplayers and their audiences, and what strategies cosplayers implement to avoid the loss of face.

The topic of the thesis regards of problems of compilation the model of existing fan-cooler systems of VVER440/V213 NPP. These systems can be operated not only normal operation conditions but also during abnormal and accidental operation of the plant, which are significantly different from those operating conditions for which were systems dedicated and designed. An advanced model, compiled as one of the subjects of this thesis, capable to predict behaviour of these systems during accidental conditions of the plant, is described within this paper. The advanced model is a part of LEAKBOX model. LEAKBOX model represents a superordinated program dedicated to modelling overall VVER 440/V213 containment response during accidental conditions of the plant focusing onto small coolant leakage in to the containment.

Ce mémoire propose d’étudier le processus narratif à l’œuvre dans la série télévisée Penny Dreadful. Il naît du constat que la plupart des études et des recherches mettant au premier plan cet objet télévisuel l’associent au concept d’adaptation. L’objectif de cette recherche est d’interroger cette filiation entre ce qui se produit dans la série télévisée Penny Dreadful et le concept d’adaptation. L’adaptation ne rend pas compte de toutes les subtilités des procédés narratifs et télévisuels de cette série télévisée. Ceux-ci se rapprochent davantage des concepts de transfiction, de Frankenfiction et de remix qui sont en marge de celui d’adaptation. Les réflexions autour de ces derniers permettent d’ouvrir un dialogue avec les notions de répétition, de variation et de sérialité propre à l’adaptation et aux études télévisuelles. Il sera question d’observer par l’analyse de séquences et l’analyse de personnage les limites et les frontières de ces concepts dans le cas des séries télévisées et de leurs possibilités créatives, dont s’approprient les fans pour fabriquer leurs œuvres. / This thesis proposes to study the narrative process at work in the television series Penny Dreadful. It arises from the observation that most studies and research about this television object associate it with the concept of adaptation. The objective of this research is to question this connection between what happens in the television series Penny Dreadful and the concept of adaptation. The adaptation does not reflect all the subtleties of the narrative and television processes of this series. These are closer to the concepts of transfiction, Frankenfiction and remix which are on the margin of adaptation. The reflections around these allow to open a dialogue with the notions of repetition, variation, and seriality proper to the adaptation and the television studies. It will be question of the limits and boundaries of these concepts in the case of television series and their creative possibilities, which fans appropriate to make their works.

The recent and rapid growth of horizontal drilling in the Anadarko basin necessitates newer studies to characterize reservoir and source rock quality in the region. Most oil production in the basin comes from the Granite Wash reservoirs, which are composed of stacked tight sandstones and conglomerates that range from Virgillian (305-299 Ma) to Atokan (311-309.4 Ma) in age. By utilizing geophysical well logging data available in raster format, the Granite Wash reservoirs and their respective marine flooding surfaces were stratigraphically mapped across the regional fault systems. Additionally, well log trends were calibrated with coincident core data to minimize uncertainty regarding facies variability and lateral continuity of these intervals. In this thesis, inferred lithofacies were grouped into medium submarine fan lobe, distal fan lobe, and offshore facies (the interpreted depositional environments). By creating isopach and net sand maps in Petra, faulting in the Missourian was determined to have occurred syndepositionally at the fifth order scale of stratigraphic hierarchy.

This thesis examines how queer identities are represented through characters in The Adventure Zone, a popular Dungeons and Dragons, fantasy comedy podcast that features unique fan contributions and deep involvement from the creators. Drawing on queer theory and theories of stereotypes and language, audience participation, and transmediation, this thesis argues that The Adventure Zone’s portrayal of queer identities both challenges dominant norms and stereotypes while also being shaped by them, and that listening to the podcast can create opportunities to discuss queer identities, LGBTQIA+ questions and the relationships between author and fans online in the Swedish EFL classroom. The findings indicate that the podcast tries to avoid but still falls into some stereotypical ideas even though it welcomes fan inclusion and representation. The character Taako is also found to be a good subject for discussions with students in terms of negotiating ideas of queerness and identity formation in accordance with the school’s democratic mission of inclusivity and sexuality, consent and relationships outlined in the new curriculum.
