Thesis (Master Diploma (Electrical Engineering))--Cape Technikon, Cape Town,1996
In order to design a coolerbox, utilising Thermo-electric technology as a heat pump, it was necessary to determine if this type of technology would be suitable for a coolerbox heat pump application. A detailed TEC (Thermo Electric Cooler) sizing estimation was done, using formulas supplied by the manufacturer, and using thermo-electric themy formulas to calculate the absolute theoretical performance parameters for a suitable TEe The correct heat pumping capability is important since.it is possible to obtain TEes with different input currents, voltages and heat pumping capabilities. Using the TEC as a heat pump, it was decided to use water cooling due to the extremely high cost of a suitable air cooled heatsink. It should be noted that to cool the hot side of theTEe a vel}' efficient heat exchanger should be used. A simulator was constructed to simulate, under variable operating temperatures and input powers, the cooling capacity of the TEC heat exchanger. The cooling characteristics were then used to determine if the theol}' and manufacturers claims correspond with the cooling characteristics of the coolerbox. It might be possible that the performance of the TEC would be drastically influenced, since installation con~itions may not be ideal when installed; and, that the manufacturers performance claims are done when the TEC is operated under ideal conditions. This would ensure optimum results because, should an under sized TEC be used, the result would be poor cooling characteristics; or, if the TEC is over sized, the coolerbox would consume too much power, resulting in an inefficient system.

Neste trabalho apresenta-se o aperfeiçoamento do anemômetro a efeito Peltier apresentado por Güths[1]. Para isso foram alteradas tanto as dimensões dos sensores como a eletrônica necessária ao dispositivo. A modificação do método de otimização dos sensores ocasionou um aumento na sensibilidade proporcionada pelo instrumento; a evolução na eletrônica possibilitou a compensação em temperatura, maior flexibilização na geração dos sinais envolvidos no anemômetro e diminuição da complexidade de construção. O dispositivo obtido mostrou-se capaz de medir velocidades entre 5 cm/s e 80 cm/s.

There is nowadays a growing demand for located cooling and stabilization in optical and electronic devices, haul of portable systems of cooling that they allow a larger independence in several activities. The modules of thermoelectrical cooling are bombs of heat that use efect Peltier, that consists of the production of a temperature gradient when an electric current is applied to a thermoelectrical pair formed by two diferent drivers. That efect is part of a class of thermoelectrical efcts that it is typical of junctions among electric drivers. The modules are manufactured with semiconductors. The used is the bismuth telluride Bi2Te3, arranged in a periodic sequence. In this sense the idea appeared of doing an analysis of a system that obeys the sequence of Fibonacci. The sequence of Fibonacci has connections with the golden proportion, could be found in the reproductive study of the bees, in the behavior of the light and of the atoms, as well as in the growth of plants and in the study of galaxies, among many other applications. An apparatus unidimensional was set up with the objective of investigating the thermal behavior of a module that obeys it a rule of growth of the type Fibonacci. The results demonstrate that the modules that possess periodic arrangement are more eficient

Dissertação para obtenção do Grau de Mestre em Energias Renováveis - Conversão Eléctrica e Utilização Sustentáveis (MERCEUS)
Uma das áreas de preocupação da actualidade é o desafio energético, a nível mundial, europeu e principalmente em Portugal. Nas conjunturas económicas e financeiras que atravessamos, a dependência energética de terceiros, a redução de custos operacionais é de principal importância para o relançamento económico do País. No entanto, devemos também ter em foco que muitas organizações têm de optimizar os recursos, com enfoque nos custos energéticos. Há que olhar para todas as formas de redução de custos com a necessária optimização de processos, equipamentos e métodos. A recuperação de desperdícios, muitas das vezes despercebidos, é uma das áreas que pode e deve ter impacto na redução da factura energética. É neste envolvimento que o estudo agora apresentado tem a sua actividade, utilizando desperdícios térmicos de um processo produtivo e recuperando essa forma de energia, transformando-a em electricidade. É uma oportunidade de recuperação das perdas energéticas relacionadas com a utilização dos equipamentos, tendo indirectamente impacto no rendimento dos processos e redução da factura ambiental através da redução de emissão de gases de efeito de estufa, reduzindo a dependência do petróleo. Dois materiais diferentes em contacto um com o outro criam uma tensão entre os materiais que depende da diferença de temperatura entre eles. Esse efeito é reversível e permite forçar a diferença de temperaturas à custa da energia eléctrica, ou obter energia eléctrica à custa da diferença térmica. Utilizando esta última, este trabalho consiste em investigar a possibilidade de utilizar este efeito, sendo a diferença térmica forçada por utilização de fluido a uma certa temperatura, num ambiente industrial e a temperatura ambiente. Esta conversão insere-se na recuperação de perdas térmicas não recuperadas, em processos produtivos e industriais. A implementação de um gerador termoeléctrico, com células de Peltier, actuando por efeito de Seebeck permite atingir esse objectivo.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2006.
Includes bibliographical references (leaf 26).
Peltier devices, also known as thermoelectric devices (TEDs), are solid state junctions of two dissimilar materials in which heat transfer and electrical conduction are coupled. A current running through a TED causes heat to flow; likewise, the presence of an external temperature gradient will induce an electrical potential across the TED. The former effect is known as the Peltier effect; the latter is known as the Seebeck effect. While TEDs are used primarily as heat pumps, they can also serve as temperature sensors. This thesis presents the design for a controller which uses a TED to simultaneously sense and control the temperature of a shape memory alloy (SMA) wire. The pulse width-modulating driving circuitry in the controller is capable of measuring the undriven voltage across the TED at a rate of 200 Hz between pulses. A low order ARX model is then used to estimate the SMA temperature. The SMA temperature can be controlled using this estimate. This method will enable the production of large arrays of TED-driven SMA tendon actuators, particularly for large DOF robotic systems.

Abstract:

Tässä pro gradu-tutkimuksessa tutkitaan digitaalisten pelien sisällönkuvailua. Niitä tarkastellaan kolmen erilaisen sisältötiedon tuottajan tekemien sisällönkuvailujen kautta. Ne edustavat kaupallista, voittoa tavoittelematonta ja säilyttämiseen pyrkivää näkökulmaa. Kaupallista tahoa edustaa pelipalvelu Steam, voittoa tavoittelematonta Suomen maakuntakirjastot ja säilyttämiseen pyrkivää verkkoarkisto Allgame. Tutkimusaineistona toimi näistä kerätty pelimateriaali, jota käsitellään teoriapohjaisen sisällönanalyysin keinoin. Teoriana toimii toisaalta muistiorganisaatioiden sisällönkuvailun teoria, erityisesti sisällönkuvailun prosessi tavoitteineen, toisaalta pelitutkimuksen puolelta pelin rakenteet. Yksi tärkeä osa ovat myös erilaiset ikäluokitusjärjestelmät, jotka tuottavat elokuvien ja pelien sisältötietoa ikäluokitusten ja haitallisesta sisällöstä kertovien symbolien avulla. Tutkimuksessa on kaksi tutkimuskysymystä: 1) mitä digitaalisten pelien sisällönkuvailussa kuvataan ja 2) mitä eroja ja yhteneväisyyksiä sisällönkuvailuissa on. Sisällönkuvailuista tarkastellaan sekä ulkoisia että sisäisiä kuvailutietoja teorian pohjalta luotujen teemojen avulla. Teemoja on neljä: 1) Sisältöä kuvaavat tiedot, 2) Ulkoasua kuvaavat tiedot, 3) Aineistolajia kuvaavat tiedot ja 4) Muut tiedot. Teemalle 1 annettiin lisäksi alateemoja, jotta sen sisältöä voitaisiin eritellä tarkemmin. Tutkimusaineisto koostui 290 pelitietueesta. Pelejä oli 34 konsolille. Tuloksista kävi ilmi, että pääpiirteissään kaikki tutkimuskohteet kuvailivat peleistä samanlaisia asioita sekä ulkoisista tunnistetekijöistä että sisällöstä. Suurin ero oli kuvailun syvyydessä. Steamin ja Allgamen kuvailut olivat aineistolähtöisiä, maakuntakirjastoilla käyttäjälähtöisiä. Kuvailuista paljastui, että etenkin maakuntakirjastoilla oli epäloogisuuksia ja selkeitä puutteita kuvailutiedoissaan, ja esimerksiki genremerkintä puuttui toistuvasti. Käytetyissä asiasanoissa oli lisäksi epäjohdonmukaisuutta ja selviä eroja kirjastojen kesken. Steamin ja Allgamen kuvailut olivat yhtenevämpiä, mutta molemmilla oli osa-alueita, joita ei ollut kuvailtu lainkaan.

Abstract:

This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.

The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.

To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product. This is a way for Peltor to give the customer a more correct delivery lead time when the order is placed.

The analysis shows that many of the delivery lead times which the company use today, are often miscalculated. The difference can be either longer or shorter than the presumed lead time. One example of a longer lead time is when the accumulated lead time is 91 days and the presumed lead time is 30 days. The difference will be 61 days, and this is the major reason why Peltor thinks products end up in the “backorder”. Our result shows that there are more factors than the delivery lead time which affects whether an order will be delivered on time or not.

Full text

Abstract:

Peliala on voimakkaasti kasvava ja kehittyvä ala ja tieteen puolella aiheeseen on viime aikoina alettu kiinnittämään enemmän huomiota. Tämän tutkimuksen on tarkoitus perehtyä pelien kehittymisen myötä lisääntyneiden automaatioiden vaikutuksista viihdyttävyyteen olivat ne sitten negatiivisia tai positiivisia. Viihdyttävyys on hankalasti tutkittava aihe siinä mielessä, että se on hyvin henkilökohtainen. Viihtymiseen vaikuttaa ihmisten luontainen halua oppia erilaisia asioita, kulttuuri joka kannustaa kilpailemaan ja yksilö itse. Yksi tärkeimmistä viihdyttävyyttä kuvaavista teorioista on flow-teoria, jonka mukaan ihminen voi nauttia mistä tahansa tekemisestä kun tietyt ehdot täyttyvät. Automaatiot ovat lisääntyneet kaikkialla ja useimmat länsimaiset ihmiset ovat nähneet erilaisia automaatteja, olivat ne sitten yksinkertaisia juoma-automaatteja tai sitten monimutkaisempia robotteja. Myös pelit sisältävät automaatiota, vaikka toisinaan rajanveto pelistä puuttuvan sisällön ja automatisoinnin välillä voikin olla hankala, mutta siitä huolimatta automaatteja on olemassa ja löydettävissä. Kysymys kuuluukin missä vaiheessa automaatit ovat jo ihmisiä haittaavia tekijöitä pelien kohdalla ja milloin ne ovat hyödyllisiä. Automaatioita ja flow-teoriaa yhdistellen voidaan pohtia mahdollisia hyviä ja huonoja puolia, jotka on vahvistettava tai kumottava tutkimuksella. Automaatioiden vaikutuksia tutkittiin määrällisellä tutkimuksella, johon osallistui Oulun yliopiston opiskelijoita. Tutkimusta varten tehtiin tietokonepeli ja peliin liittyvä kysely, johon pelaajat vastasivat peliä pelattuaan. Tutkimuksessa saatiin selville yksinkertaisimpien automaatioiden toimivan yhteisvaikutukseltaan hyvinä mutta monimutkaisempien toimintojen automatisoinnin vaikuttavan negatiivisesti.

Full text

Abstract:

Matkailu on yli miljardin vuotuisen ulkomaanmatkan myötä valtava liiketoiminnan ala ja kasvaa edelleen. Pelien pelaamista ei ehkä helposti yhdistä matkailuun, mutta mobiililaitteiden kehittymisen ja yleistymisen myötä pelaamisesta on tullut mahdollista ajasta ja paikasta riippumatta. Paikkasidonnaisissa peleissä on potentiaalia hyödynnettäväksi myös matkailussa. Peleillä on mahdollista markkinoida kohdetta, esitellä sen nähtävyyksiä, vaikuttaa matkailijoiden käyttämiin reitteihin ja syventää matkakokemusta. Näin voidaan mahdollisesti vaikuttaa matkakohteen valintaan, siellä vietettyyn aikaan ja saada halpaa mainosta, mikäli kävijä jakaa kokemuksiaan. Matkailijat ovat jo vuosia tottuneet käyttämään älypuhelimiaan ja muita mobiililaitteitaan mm. navigointiin, tiedonhakuun, suositteluihin ja sosiaalisen median päivitysten tekemiseen, joten samojen laitteiden hyödyntäminen viihdyttävällä tavalla markkinoinnissa on luontevaa. Pelielementtien käyttämistä muissa kuin pelikonteksteissa kutsutaan pelillistämiseksi ja sen on ennustettu olevan tulevaisuuden trendi matkailussa. Vaikka matkailu on vanha ala, on sekin kuitenkin altis muutoksille. Peli- ja matkailuala ovat myös varmasti kiinnostuneita toistensa suurista asiakasmääristä. Suositun pelin kehittäminen ei kuitenkaan ole yksinkertaista ja onnistumisten taustalla on lukuisia epäonnistumisia. Siksi onkin otettava oppia harvoista onnistuneista peleistä. Varsinkin 17 vuoden ikään ehtinyt geokätköily (geocaching) on noin 3 miljoonalla aktiivisella harrastajallaan kiinnostava ilmiö. Kätköjä on miltei jokaisessa maailman valtiossa, mutta kukin geokätkö on kuitenkin sidottu sijaintiinsa, eikä sitä voi löytää menemättä sinne. Usein kätkö esittelee jonkin esittelemisen arvoisen paikan, jota ei välttämättä turistioppaasta löydy ja joka voi olla suurimmalle osalle paikallisiakin tuntematon. Näin matkailijalle on mahdollista tarjota aivan uudenlaisia kokemuksia.

Abstract:

The purpose of this thesis has been to determine experimentally how good a peltier element is to convert waste heat from wood burning. Three different peltier elements were used in a comparison study. The comparison was mainly done to know how much power could be obtained from each element. Even, a circuit with a step-up function has been created to give a higher output voltage than the peltier element itself. The result of the experiments was a low output power, the highest value reached 2.18W. Also, the Carnot efficiency has been calculated for the three different elements and the efficiency ranged between 14 and 33%. From the circuit a constant 3.3V output was delivered. The main conclusion of this project is that furthermore Studies are needed in the material field because the elements available at the market today have too low efficiency.

Abstract:

Change is inevitable for any organisation to ensure effectiveness and to stay competitive in today's business environment. Change should be managed proficiently to ensure that the required outcomes are achieved. Conversations with employees of ABSA Bank in the Northern Cape region revealed that the perception of the management of change is that it is less than effective due to general dissatisfaction regarding elements such as training, communication and support during change efforts. The purpose of this study is to measure the effectiveness of change management in ABSA Bank. The importance of this being that negativity and wrong perceptions regarding change can lead to resistance that can destroy any potential change effort in ABSA Bank. The literature study revealed that in order to manage change effectively, proven change management models are to be used and the elements within the model need to be managed convincingly. A questionnaire was utilised as the measuring instrument in the empirical study to obtain information that underscored the questioning of the effectiveness of the change management model as well as the management of the elements in the model of ABSA Bank. Recommendations are made to the management of ABSA Bank, based on the results of the study, on how to improve the level of effectiveness of the change management exercise in ABSA Bank.

Abstract:

Religious and cultural practices and values play an important role in funerals and how funerals should be conducted. This creates considerable conflict in the African customary law among heirs and family members when someone dies and where there must be decided who should bury the deceased and where the deceased must be buried. The whole issue can be brought under the term "burial right". This "right" to bury a deceased family member can be problematic and can be divided into two aspects. The first aspect deals with the question of who should bury the deceased and the second with where the deceased must be buried. These two questions give rise to considerable confusion in the courts and there is no agreement on the exact principles that must be applied. The where aspect is partially regulated by the Extension of Security of Tenure Act 62 of 1997. There is no law that regulates the who aspect and the courts follow different approaches to find a solution. The courts' decisions are sometimes based on common law and the position of Voet, while other decisions are based on African customary law. The courts sometimes apply a combination of the principles of common law and customary law to ensure a fair result. The different approaches lead to a significant degree of legal uncertainty. The uncertainty in the legal position on burial rights can pose significant problems for the estate planner. The estate planner must be able to give effect to a person's wishes, as well as advise his or her client about the prevention of conflict between family members. Burial rights are one of the causes of conflict and the estate planner must be able to give advice to a person living according to the customs and habits of African customary law burial rights. It is therefore important iv that the estate planner should have knowledge of the legal position in respect of burial rights in the context of African customary law, and of the steps they can take to prevent potential conflict situations in this regard. One way to resolve the conflict between family members would be to make funeral arrangements by recording funeral wishes in a will.

Abstract:

Tässä kirjallisuuskatsauksena toteutetussa kandidaatintutkielmassa tutustutaan suomalaiseen varhaiskasvatuksen kentällä tapahtuneeseen digitaalisia pelejä koskeviin tutkimuksiin. Lähestyn tutkimusta systemaattisen kirjallisuuskatsauksen näkökulmasta. Tutkimukseni tavoitteena oli selvittää, millaista varhaiskasvatuksen tutkimusta Suomessa on tehty, joka liittyy digitaalisten pelien pelaamiseen. Työssä esitellään tieto- ja viestintäteknologiaa sekä mediakasvatusta varhaiskasvatuksen näkökulmasta, joiden pohjalta digitaalisia pelejä käsitellään varhaiskasvatuksessa. Suuri osa Suomessa tehdyistä digitaalisiin peleihin koskevista tutkimusta on tehty Ekapeliin liittyen. Tästä syystä Ekapelillä on suuri rooli myös minun työssäni. Annikka Suoninen on kerännyt suuret määrät tietoa 0—8-vuotiaiden median käytöstä. Suonisen keräämä tieto antaa arvokasta tietoa lasten median käytön muutoksista. Toinen asia jonka halusin selvittää oli se, että miksi digitaaliset pelit ovat osa uutta varhaiskasvatussuunnitelmien perusteita. En löytänyt suoria vastauksia kysymykseen, mutta löysin kuitenkin vihjeitä, joiden avulla pystyin tekemään omia johtopäätöksiä, miksi digitaaliset pelit ovat saaneet jalansijan varhaiskasvatussuunnitelmien perusteissa. Suomessa tutkimukset ovat aluksi keskittyneet siihen, miten oppimispelit sopivat oppimisen tueksi varhaiskasvatuksessa. Myöhemmin tutkimukset ovat laajentuneet käsittelemään digitaalisia pelejä osana lasten median käyttöä sekä lasten mediakulttuuria.

Abstract:

Pilot scale sintering experiments were performed, aiming at comparing the quality of the sinter produced from a reference sintering blend with that of sinters resulting from other blends, in which the sinter feed in the reference blend was replaced by 50% and 100% pellet screenings and micro pellets and also by 25%, 50%, and 100% pellet feed. The following parameters of the sinters were assessed: a) production: granulation index, sintering time, < 5mm return, total return, coke rate and productivity;b) quality: shatter index, tumble index, RDI and reducibility; c) sinter structure: microstructural analysis. The results showed that pellet feed may reach 6.25% in a sintering blend (25% substitution). The productivity in the sintering experiments was technically equal to that achieved with the reference blend. The quality indexes and the structure also did notshow significant differences. Pellet screenings and micro pellets may participate up to 12.5% in the sintering blend (50% substitution). The productivity in the sintering experiments was technically equal tothat achieved with the reference blend. The quality parameters shatter index, tumble index, RDI and reducibility reached levels slightly inferior to those achieved with the reference blend. In the case of micro pellets only the parameters shatter index and RDI stayed slightly below the levels for the reference blend. All the quality parameters may be improved with a higher addition level of coke, for the fuel consumption was lower than that for the reference blend
Foram efetuados experimentos em sinterização piloto, com o objetivo de comparar a qualidade do sínter produzido com uma mistura de sinterização de referência, com a de sínteres resultantes de outras misturas, nas quais um sinter feed que participa em 25% damistura de referência foi substituído por 50% e 100% de pellet screenings e micro pellets e por 25%, 50% e 100% de pellet feed.Foram analisados os seguintes parâmetros dos sínteres produzidos:a) produção: índice de granulação, tempo de sinterização, retorno < 5mm, retorno total, coke rate e produtividade; b) qualidade: shatter index, tumble index, RDI e redutibilidade; c) estrutura do sínter: análise da microestrutura. Os resultados mostraram que o pellet feed pode participar em até 6,25% em uma mistura a ser sinterizada (25% de substituição). A produtividade nos ensaios de sinterabilidade foitecnicamente igual à de referência. Os índices de qualidade e a estrutura também não apresentaram diferenças significativas. O pellet screenings e o micro pellets podem participar em até 12,5% em uma mistura de minérios a ser sinterizada (50% de substituição). A produtividade nos ensaios de sinterabilidade foi tecnicamente igual à de referência. Os parâmetro de qualidade shatter index, tumble index, RDI e redutibilidade foram levemente inferiores no caso de pellets screenings. Para o micro pellets apenas os parâmetros shatter index e RDI ficaram um pouco abaixo dos obtidos com a mistura de referência. Todos esses parâmetros de qualidade poderão ser elevados com uma maior adição de carvão, tendo em vista que o consumo de combustível foi inferior ao da mistura de referência

Abstract:

In questa tesi si è studiato come affrontare il problema dello smaltimento di calore attraverso dispositivi termoelettrici come le celle di Peltier. I punti focali di cui si è discusso sono il funzionamento fisico dei moduli, le loro figure di merito ed i fattori che le determinano, le applicazioni in cui le celle vengono utilizzate e due esempi di dimensionamento. In particolare all'ultimo punto si sono distinti due ipotesi di utilizzo: la prima ha riguardato il dimensionamento di una modulo di Peltier accoppiato da un dissipatore passivo, mentre nella seconda si è visto come utilizzare questi dispositivi in presenza di un controllore TEC ed un dissipatore attivo. Successivamente alle due ipotesi di funzionamento è stato fatto un confronto delle soluzioni proposte analizzandone vantaggi e svantaggi, tra cui costi e consumi in potenza.

Abstract:

A Pelton design software is currently being developed at the Waterpower laboratory at NTNU. The motivation behind this software is to streamline the parametric design process for Pelton turbines. A numerical flow model is a cornerstone in this application, but the lack of a bucket geometry and model runner has prevented the development of such a model. DynaVec, a turbine producer who specializes on sediment erosion and corrosion problems, offered to help by providing a bucket geometry and a model runner.The objective of this Master's thesis was to develop and validate a CFD model that predicts the torque applied to a non-stationary Pelton bucket, subject to a high-speed water jet. The numerical model was based on a method proposed by DynaVec, and the bucket geometry used in the simulations was identical (1:1) to the model runner.Numerous simulations were conducted, testing mesh dependency and different operational points (e.g. head). Mesh independence occurred at approximately 4.5 million elements. Furthermore, simulations of varying heads showed that the model may be independent of the head (40-80m), but this was not verified properly.Experiments showed that the numerical prediction was fairly accurate. A comparison of the numerical and experimental measurements showed that the CFD model over-predicts the torque by approximately 1.5%. This prediction was validated for the specific geometry used in the simulations, and a head of 75m.Overall, the results suggest that the numerical model is promising as a parametric design tool, but further development is required to obtain a true validation of the model.Task three and four were changed in agreement with Ole Gunnar Dahlhaug, because Solemslie's design program was delayed. In essence, the parametric study proceeded in favor of the development of a CFD model. To ensure that this work would benefit future research, especially students at the Waterpower laboratory, a detailed procedure for the CAD modeling, meshing and physical setup was included in the Appendix.

Abstract:

Winter precipitation is an important issue in Canada because of its common occurrence and associated destructive consequences. Prediction of the precipitation type when temperatures are near 0°C is often difficult because so many types can occur. This study examines the microphysics of ice pellet formation, in particular the ability of these to form aggregates and the consequences of these aggregates. This issue was examined by modelling the freezing of a distribution of precipitation particles as they fall through the atmosphere and interact through collisions. Three mechanisms for aggregation were examined, collisions among the particles involved in these mechanisms were modelled and the relative importance of each mechanism was determined. It is shown that, for the conditions considered, aggregates are often able to collect freezing rain drops and that aggregation can sometimes be very effective at eliminating freezing rain but the conditions need to be precise for this to occur.
Les divers types de précipitations observées durant les tempêtes hivernales sont souvent la cause d'inconvénients durant cette période au Canada. Il est difficile de prédire ces divers types de précipitations du fait de leur sensibilité à certaines conditions atmosphériques, en particulier à des températures près de 0°C. Cette étude examine la microphysique de la formation des granules de glace. Plus précisément, la capacité de ces granules de former des agrégats et les conséquences de ces agrégats sur les autres types de précipitation présents. Cette recherche repose sur l'étude du regel d'une distribution de pluie verglaçante dans une atmosphère sous le point de congélation à l'aide de simulations incluant les interactions entre particules. Une attention particulière a été prêtée sur trois principaux aspects. Premièrement, trois mécanismes formant des agrégats de particules ont été étudiés. Deuxièmement, les collisions parmi les particules entraînées dans ces mécanismes ont été modélisées. Finalement, l'importance relative de chaque mécanisme a été déterminée. Les résultats illustrent que pour les conditions atmosphériques considérées, la pluie verglaçante est souvent collectée par les agrégats de particules formés durant leur descente dans l'atmosphère. De plus, l'agrégation de particules s'avère efficace à l'élimination complète de la pluie verglaçante dans des conditions atmosphériques précises et favorables.

Abstract:

Blood glucose management in Type 1 diabetes is crucial in preventing several diabetic complications. Blood glucose management is a complex task requiring diabetics too carefully administer the correct dosages of insulin by taking their blood glucose levels, food consumption, exercise, stress, illnesses and several other factors into account. Improved bolus calculation greatly aids in controlling blood glucose levels within a tight range. This study investigates how the ets-concept (Equivalent Teaspoons Sugar-concept) can be used to develop products to calculate insulin boluses. A cellular phone based software application was developed to calculate insulin boluses using the ets-concept. This product was tested in a clinical trial. A blood glucose characterization procedure was also developed to characterize the blood glucose response of a Type 1 diabetic to carbohydrate ingestion and insulin administration. The characterization procedure was used during the clinical trial to characterize patients in order to customize the bolus calculation products for the specific diabetic user.

Abstract:

Cette thèse présente un nouveau procédé d'adsorption modulée en température base sur l'utilisation d'éléments thermoélectriques et d'un nouveau composite adsorbant à base de graphite expansé recomprimé. Le contexte de ce travail est la recherche de petits dispositifs compacts et souples adaptés à des installations embarquées. L’adsorption est un procédé exothermique dans lequel une augmentation de température provoque une diminution de quantité adsorbée. Les procédés classiques utilisent des gaz chauds ou de la vapeur pour régénérer le lit adsorbant. Les étapes de chauffage, de séchage et de refroidissement sont en général très longues ce qui impose des temps de cycles longs et l'emploi de grandes quantités d'adsorbant. Le chauffage par conduction à travers des surfaces de transfert est limité par la faible conductivité thermique des milieux poreux. La combinaison de graphite expansé naturel recomprimé avec un composé adsorbant tel que du charbon actif, permet d'obtenir un composite présentant à la fois des propriétés d'adsorption, et des propriétés de transfert de chaleur. Le nouveau composite fabriqué présente en effet une conductivité thermique six cent fois supérieure à celle d'un lit de charbon actif classique pour une perte de capacité d'adsorption d'environ 20%, et cela sans diminution de la perméabilité. Les modules thermoélectriques, pompes à chaleur sans pièces mobiles, permettent de refroidir le milieu poreux pendant l'adsorption et de chauffer celui-ci par simple inversion du sens du courant électrique pour la régénération. Les résultats obtenus montrent que des cycles d'adsorption/désorption d'une dizaine de minutes au lieu d'une dizaine d'heures pour des procédés classiques, sont réalisables. Cette étude porte à la fois sur une étude expérimentale et des résultats de simulation. Les expériences cycliques sont des essais d'orientation et d'évaluation.

Abstract:

Since the need of energy conservation has become more and more urgent in the past decades, there has been an increased interest in the study and development of more efficient energy conversion systems. One of the fields that have arisen from that endeavor is a branch of physics called Finite Time Thermodynamics (FIT). It may be said that FIT was initiated through the famous paper by Curzon and Ahlborn (1975) that established new bounds on the efficiency of a finite time Carnot heat engine. Before, the traditional treatments gave a fundamental upper limit on the efficiency of any heat engine. However, this figure, the well-known Carnot efficiency, is far too optimistic in comparison to real heat engines. The reason lies in the fact that the traditional Carnot engine is operating infinitely slowly, thus having zero power output. Curzon and Ahlborn were able to improve upon this treatment and to set an upper limit on engines producing finite power.

Abstract:

Käytettävyydestä on tullut eräs tärkeimmistä sovellusten kehittämisen osa-alueista. Erityisesti peleissä käytettävyys ja pelattavuus ovat yhtenäinen osa pelikokemusta eli millaisen mielikuvan peli käyttäjälleen antaa. Tutkielmassa tarkastellaan tähän asti ilmestyneissä julkaisuissa todettuja pelattavuus-heuristiikkoja ja niiden soveltuvuutta pelisuunnittelussa käyttäen tutkimusmenetelmänäni kvantitatiivista tutkimusta. Tutkimusosion päätavoitteena oli priorisoida aikaisemmassa tutkimuksessa luodun peliheuristiikkalistan heuristiikat yleisesti ja genreittäin. Pelien kehityksen osa-alueena käytettävyyden tutkimus on suhteellisen tuore käsite. Viime vuosina pelien heuristiikkatutkimuksia on julkaistu suhteellisen kiitettävästi ja niitä julkaistaan jatkuvasti lisää. Tutkimuksissa on todettu peleille suunnatuista heuristiikoista olevan suuri hyöty evaluoinnissa. Heuristiikkojen avulla saadaan suhteellisen nopeasti aikaiseksi taulukoitavia tuloksia, joista pelin kehittäjät näkevät nopeasti käytettävyyteen liittyviä ongelmakohtia. Kuitenkin, vaikka heuristinen evaluointi lupaa edullista pelattavuuden arviointimenetelmää, on se täynnä subjektiivisesta tulkinnasta johtuvia ongelmia ja yhä useampia kilpailevia ja ristiriitaisia heuristiikkalistoja. Tämän vuoksi nykyisistä tutkimuksista saatujen heuristiikkalistojen tutkiminen ja yksittäisten heuristiikkojen priorisointi on tärkeää pelattavuuden arvioinnin kannalta. Tutkimuksessa saatiin selville osa-alueittain tärkeimmät ominaisuudet. Game play -kategoriassa on tärkeintä selkeät tavoitteet, sopivasti haastetta, haasteiden on oltava reiluja ja pelin on oltava ennen kaikkea hauska, jonka jälkeen voidaan vasta keskittyä pelimekaniikkaan ja grafiikkaan. Game story -kategoriassa tarina on tärkeässä osassa. Pelin tulokset ovat oikeudenmukaisia, pelaajalla on tunne hahmon hallinnasta ja peli vaikuttaa pelaajan tunteisiin. Game mechanics -kategoriassa painottuu kontrollien tärkeys. Mekaniikka/kontrollit ovat johdonmukaisesti sijoitettu. Mekaniikka on helppo oppia, mutta vaikea hallita.

Abstract:

Henkilökohtainen suunnitelmallisuus ja aikataulutus on monille ongelmallista. Näin on erityisesti nuorilla aikuisilla, koska he eivät ole vielä ehtineet harjoitella sitä paljon. Hyötypelit ovat pelejä, joiden pääasiallinen tarkoitus on jokin muu kuin viihde. Niiden avulla on mahdollista harjoitella monia taitoja — myös ajankäytön hallintaa. Tässä työssä tutkittiin kyseistä aihetta suunnittelemalla ja toteuttamalla prototyyppi tietokonepelistä, jossa pelaajat käsittelevät opiskelun, työn ja vapaa-ajan tasapainoa ja etenevät kohti itse asettamiaan tavoitteita. Peli on vuoropohjainen ja lautapelityylinen. Pelissä rajallinen määrä aikaa investoidaan haluamallaan tavalla kullakin vuorolla ja suunnitelmallisella toiminnalla pelaaja menestyy, saavuttaen tavoitteensa nopeammin. Ensimmäisenä tavoitteensa saavuttanut pelaaja voittaa. Peli toteutettiin java-ohjelmointikielellä käytettäväksi tavallisissa kotitietokoneissa. Konseptia ja prototyypin soveltuvuutta tarkoitukseensa arvioitiin koekäyttäjien avulla. Koekäyttäjät pelasivat peliä 40 minuuttia, minkä jälkeen he vastasivat kyselyyn ja heitä haastateltiin. Kyselyssä esitettiin kymmenen prototyyppiä koskevaa väittämää, joiden paikkaansa pitävyyttä koekäyttäjät arvioivat seitsenportaisella Likert-asteikolla. Haastattelu oli osittain strukturoitu. Koekäyttö tehtiin pareittain kymmenen hengen joukolle. Koekäyttäjien arvioiden mukaan ajankäytön hallinnan kehittäminen hyötypelillä on mahdollista. He myös arvioivat prototyypin vastaavan hyvin todellisen elämän haasteita. Tutkimuksessa vahvistui käsitys siitä, että hyötypelin täytyy olla hyvä ollakseen aidosti hyödyllinen. Tutkimuksessa ilmeni myös hyvän pelin tekemisen olevan hyvin haastavaa
Personal orderliness and scheduling is problematic for many people. This is especially true for young adults since they have not yet mastered them through practice. Serious games are games that have some other primary purpose than entertainment. With serious games it is possible to practice many different skills — including time allocation. In this thesis the subject was studied by designing and implementing a prototype of a computer game in which the players balance their studies, work and spare time, progressing towards goals they have set for themselves. The game is turn-based with a board game style. Players have limited amount of time to invest as they choose each turn. By planning well they prevail in achieving their targets faster. The player who reaches his or her goals first is the winner. The concept and the prototype’s suitability to it’s purpose was evaluated with test users. The test users played the game for 40 minutes, after which they filled a survey and were interviewed. The survey consisted of ten claims regarding the prototype. The test users assessed those claims on a seven step Likert-scale. The interview was partially structured. Testing was done in pairs and there were a total of ten test users. According to test users it is possible to improve one’s time allocation skill with a serious game. They also thought the prototype simulated real-life challenges well. This research strengthened the understanding that to be truly beneficial a serious game has to be good. It also became apparent that creating a good game is a challenging task
