Повний текст джерелаThis research has been conducted by focusing on the trajectories of semiotic ensembles from various contexts that stand-up comedians exploited for aesthetic and communicative purposes. I apply the social semiotic theory of multimodality (Kress and van Leeuwen, 2001, 2006), and the notions of semiotic remediation (Bolter and Grusin, 1996, 2000) and resemiotization (Iedema, 2003) to selected audiovisual recordings performances of Trevor Noah and Loyiso Gola from South Africa; and Atunyota Akporobomeriere (Ali Baba) and Bright Okpocha (Basket Mouth) from Nigeria. I explore the trajectories of semiotic resources that the comedians used across modes, contexts and practices. I also trace the translation and interpretation of socio-cultural and political materials by South African and Nigerian stand-up comedians’ performances. The idea is also to examine the extent to which the socio-cultural and political contexts of both countries have differential effects on the choices in the semiotic resources used in the reconstruction of meanings, including cross socio-cultural taboos. The study reveals that combinations of various semiotic materials ranging from political, sociocultural, religious and personal lifestyles are remediated (repurposed) for comic and aesthetic effects. This involves translating and re-interpreting the semiotic resources across contexts and practices. In this regard, the study showed how the artists rework verbal language, images, socio-political discourses and other semiotic material for new meanings. It also reveals that although the choices of materials are similar, there is a tendency of localizing semiotic resources to particular localities and audiences, so that each artist’s performance comes out as unique to the person. The study concludes that language alone is not at the core of communication as other semiotic modes (in addition to languages) are integrated interweaving resources to make meaning. The direction of the modes or resources is multidimensional. All the spoken texts, all the non-linguistic modes: gestures, stance, movements, running on stage, postures, mimicking and others, perform vital roles to recontextualize meanings in stand-up comedy performance. Therefore, the study opens up new perspectives on social semiotic approaches to multimodality, as well as on language social semiotic and to theory and media studies. The contribution also answers the call to expand the understanding and research on the theory of ‘multimodality’ and the various concepts such as semiotic remediation and resemiotization associated with it.

The movement from middle school to high school is a crucial period as students frequently have a difficult time adjusting to the high school environment and often experience a decline in their grades once they leave middle school and enter ninth grade (DeLamar & Brown, 2016; Ellerbrock & Kiefer, 2014; Fulk, 2003; Mizelle & Irvin, 2000; Neild, 2009). Many students who drop out of school do so in ninth grade and do not graduate on time with their classmates (Asplaugh, 1998; Bottoms, 2002; Fulk, 2003; Neild, Stoner-Eby, & Furstenberg, 2008). The transition from middle school to high school involves communication between school personnel, students, and their parents to ensure it is successful. The components of a successful middle school to high school transition program address the academic, procedural, and social challenges students face during this time (Akos & Galassi, 2004; Anderson, Jacobs, Schramm, & Splittgerber, 2000; Block, 2016; Cauley & Jovanovich, 2006; Ellerbrock, Denmon, & Owens, 2015; Smith, Feldwisch, & Abell, 2006). Richard Samuel School (RSS), a stand-alone ninth-grade center, has addressed transition challenges for over 25 years. The focus in this single case study research was to examine the reasons for the development of this unique school configuration, as well as the programmatic structures created to address students’ academic, procedural, and social concerns, through the perceptions of former students, staff, and administrators. An additional focus was to identify the effectiveness, benefits, and drawbacks of the program design which addressed the middle school to high school transition for all students at RSS. The study covered the program during the first 10 years of its existence, from its inception in 1993 until 2003. The results of this study contribute to the research regarding impactful transition programming from middle school to high school.

Повний текст джерелаInvesteringar i privat infrastrukturskuld har ökat de senaste åren [15]. För βägare av portföljer med investeringar i samtliga tillgångsslag är det viktigt att kunna urskilja risken från de olika innehaven i portföljen. Det finns många utmaningar vad gäller modellering av privat infrastrukturskuld, så som den begränsade mängden privat data och publika index för privat infrastrukturskuld. I denna uppsats föreslås två tillvägagångssätt för att modellera privat infrastrukturskuld i en parametrisk riskfaktormodell. Båda tillvägagångssätten eftersträvar att inkorporera intäktsrisk, vilket är risken som beror på den underliggande intäktsmodellen i ett infrastrukturprojekt eller företag. Intäksrisk delas in i intäksmodellerna "merchant", "contracted" och "regulated", då en skillnad i spreadnivå mellan privata infrastrukturskuldinvesteringar kan urskiljas med denna kategorisering. Skillnaden i spreadnivå mellan de olika kategorierna används för att estimera β -koefficienter som används i båda tillvägagångssätten. Spreadnivåerna erhålls från ett dataset och från en tidigare studie. I det första tillvägagångssättet, den systematiska riskfaktor-ansatsen, introduceras tre systematiska riskfaktorer som representerar infrastrukturskuldinvesteringar med en viss intäktsmodell. Risken eller volatiliten för dessa faktorer är densamma som volatiliteten för ett index för infrastrukturskuld justerat med en av β -koefficienterna. I det andra tillvägagångssättet, den idriosynktratiska riskterm-ansatsen, adderas tre konstanta risktermer för intäktsmodellerna för att fånga upp intäktsrisken i de privata infrastrukturinvesteringarna. De konstanta risktermerna är estimerade med β -koefficienterna och en historisk volatilitet för ett index för infrastrukturskuld. För båda tillvägagångssätten presenteras riskmåtten stand-alone risk1 och risk contribution2. Riskmåtten ges för ett block av samtliga faktorer för infrastrukturskuld och för varje enskild faktor inom detta block. Båda tillvägagångssätten borde möjliggöra bättre förklaring av risken för privata infrastrukturskuldinvesteringar i en större portfölj genom att ta hänsyn till intäktsrisken. De två tillvägagångssätten för modelleringen har dock ej testats. Därför kan ingen slutsats dras med hänsyn till huruvida ett av tillvägagångssätten är bättre än de som används för närvärande för modellering av privat infrastrukturskuld.

Повний текст джерелаRésumé Que le véritable substitut se lève: Une critique pluraliste des décisions partagées aux soins intensifs de nouveau-nés À l'unité des soins intensifs néonataux, les décisions portant sur le traitement des nouveau-nés impliquent une multitude d'influences normatives dont certaines peuvent entrer en compétition. Mettant à contribution le pluralisme juridique critique développé par Martha-Marie Kleinhans et Roderick Macdonald, cette thèse offre une analyse des interactions normatives qui émergent lorsque parents et personnel traitant se rencontrent au chevet d'un nouveau-né à l'état de santé précaire. En me basant sur le modèle de décision partagée favorisé par la Société Canadienne de Pédiatrie dans son énoncé de position sur les décisions médicales concernant les enfants et les adolescents, je soutiens qu'en contexte de soins intensifs néonataux, le consentement des parents n'est recherché qu'en cas d'incertitude ou de neutralité thérapeutique et non lorsque l'intérêt de l'enfant peut être adjugé avec certitude en vertu de critères médicaux. Par conséquent, la dimension « partagée » du processus décisionnel ne prend place que lorsque le personnel traitant estime qu'une incertitude suffisante justifie l'implication des parents dans le processus décisionnel. À l'aide d'études ethnographiques sur l'expérience vécue des parents à l'unité des soins intensifs néonataux, je souligne la différence marquée entre l'autorité décisionnelle donnée aux parents par le droit formel canadien, incluant les directives médicales, et l'autorité qu'ils exercent de facto au chevet de leur enfant. Je conclue par une réflexion critique sur l'émergence du pluralisme juridique aux soins intensifs néonataux par les dynamiques d'accommodement ou de résistance des parents envers les normes médicales en vigueur.

Повний текст джерелаBoreal black spruce forests (Picea mariana (Mill.) BSP) store great amounts of carbon in the living biomass and in the soil. Fire regime characteristics (e.g. fire return interval, fire intensity, fire season and severity) play a central role in the storage and flow of carbon, by modifying the distribution and transfer of material among pools. There is little doubt in the scientific community that climate change will cause changes in the temporal and spatial variables that control the frequency and severity of fires. A demographic diameter-class structured model was developed to simulate boreal carbon storage under different fire regimes. This approach incorporates the effect of fire intensity and stand structure measures to simulate fire severity, measured as the proportion of overstory tree mortality. The model allows quantifying and mapping average regional estimates of current and future carbon stocks for the black spruce-feathermoss bioclimatic domain of northern Québec. Simulation results suggest that fire severity increases with fire the intensity. Stand structure is one of the factors that explains the observed variation in boreal fire severity. We simulated carbon stocks and fluxes under seven levels of fire return interval (FRI) and two fire seasons. We tested for an effect of these parameters on average carbon stocks. Carbon stocks were sensitive to IRF's between 60 and 300 years. Soil C stocks were lower for summer fires that occurred during shorter IRF. Finally, we investigated the short-term impacts of climate change under four climatic periods: 1980-2010, 2010-2040, 2040-2070 and 2070-2100. Historical and future FRI maps and historical and forecasted weather data estimated by CanESM2 RCP8.5 were used to drive the growth of forests, decomposition rates, fire regime and C dynamics. In our simulation experiments, the accumulation of carbon in the ecosystem was reduced by 11% by the end of 2100. The results of this study suggest that black spruce forest could be losing their capacity to sequester and store organic C over the next coming decades due to climate change effects on the fire regime and on forest growth.

Повний текст джерелаCuatro diferentes controladores basados en técnicas de modos deslizantes fueron diseñados en el marco de referencia dq. Las leyes de control obtenidas regulan la amplitud de la tensión de estator independientemte del valor de la carga. Adicionalmente, sólo las medidas de tensión y posición del rotor (para calcular la transformada dq) son necesarias. La estabilidad de los puntos de equilibrio obtenidos fueron probados al menos utilizando anàlisis de pequeña señal.
Se realizó la validación por simulación y experimental de cada controlador en diferentes escenarios. Los resultados obtenidos validan los diseños y muestran las principales ventajas y desventajas de el sistema en lazo cerrado.
El capítulo 2 cubre los problemas de modelado de la màquina sincrónica de rotor bobinado. Partiendo de las ecuaciones trifásicas generales, y utilizando la transformada de Park, se encontraron el modelo en dq del generador sincrónico de rotor bobinado (WRSG) en isla, alimentando tanto carga resistiva como inductiva. Los puntos de equilibrio del sistema obtenido fueron analizados y calculados, luego se definió el objetivo de control. Finalmente, se obtuvieron modelos lineales aproximados y sus respectivas funciones de transferencia.
Los controladores PI son los más usados en la industria porque ofrecen buen desempeño y son sencillos de implementar. En el capítulo 3, se obtuvieron las reglas de sintonización para el controlador PI, y se analizaron estos resultados con el objetivo de proponer nuevos controladores que mejoraran el desempeño de la clásica aproximación PI.
El esquema de control en modos deslizantes para la WRSG conectada a una carga resistiva fue diseñado en el capítulo 4. Éste, también incluye un completo análisis de estabilidad del sistema en lazo cerrado.
El capítulo 5 presenta dos diseños basados en modos deslizantes para regular la amplitud de la tensión de estator para el WRSG actuando en isla. Ambos diseños usan la componente d de la tensión de estator en la función de conmutación. El primer caso es un control anidado, donde un lazo externo PI es añadido para proveer la referencia de la componente d de la tensión. En la segunda aproximación un término integral es añadido a la superficie de conmutación.
El caso de alimentar una carga inductiva es estudiado en el capítulo 6. El controlador requiere una extensión dinámica debido a que la amplitud de la tensión de estator es una salida de grado relativo cero. Como resultado, un controlador robusto, que no depende de los parámetros de la máquina ni de los valores de carga es obtenido.
En el capítulo 7 los resultados de simulación y experimentales para los controladores diseñados para el WRSG actuando en isla son presentados. En primer lugar, una descripción completa del banco es presentada. Esta incluye detalles de la etapa de adquisición de datos y de la DSP utilizada. En segundo lugar, se hace la descripción del procedimiento de simulación. Luego, las simulaciones y experimentos, que contienen diferentes escenarios, con cambios de referencia y variaciones de carga para cada controlador son presentados.
The control of the stand-alone the wound rotor synchronous generator has been analyzed in this dissertation. For this islanded configuration, the mechanical speed determines the frequency, and the rotor voltage is used to set the stator voltage amplitude. Due to the electrical time constant is so fast compared with the mechanical time constants, the mechanical speed was considered constant and externally regulated and the research was focused on the stator voltage amplitude regulation.
Four different controllers based on sliding mode control techniques were designed in the dq reference frame. The obtained control laws regulate the stator voltage amplitude irrespectively of the load value. Furthermore, only voltage and rotor position measures (to compute the dq transformation), are required. The stability of the obtained equilibrium points was proved at least using small-signal analysis.
Simulation and experimental validation of each controller containing several scenarios were carried out. The obtained results validate the designs and show the main advantages and disadvantages of each closed loop system.
Chapter 2 covers the modeling issues of the wound rotor synchronous machine. From the general three-phase dynamical equations, and using the Park transformation, the dq-model of the stand-alone wound rotor synchronous generator feeding both a resistive and an inductive load are obtained. Equilibrium points of the obtained systems are analyzed and, after defining the control objective, the desired equilibrium points are computed.
Finally, linear approximated models are obtained and their transfer functions are also presented.
PI controllers are the most used in the industry because they offers good performance and are easily implementables. In Chapter 3 we obtain the tuning rule for the PI controller, and we analyze these results in order to propose new controllers which improve the classic PI approach.
The sliding mode control scheme for the WRSG connected to a resistive load is designed in Chapter 4. It also includes a complete stability analysis of the closed loop system.
Chapter 5 presents two sliding mode designs to regulate the stator voltage amplitude for a stand-alone wound rotor synchronous generator. Both use the stator voltage d-component error in the switching function. The first case is a nested controller, where an outer PI loop is added to provide the proper d-voltage component reference. In the second approach an integral term is added to the switching function.
The case of feeding an inductive load is studied in Chapter 6. The controller introduces a dynamic extension because the stator voltage amplitude is a zero relative degree output. As result, a robust controller, which neither depends on the machine parameters nor on the load values, is obtained.
In Chapter 7 the simulation and the experimental results of the designed controllers for the stand-alone wound rotor synchronous generator are presented. Firstly, a complete description of the bench is provided. It also includes details of the data acquisition stage and the used DSP card. Secondly, the description of the simulation procedure is commented. Then, the simulation and experiments which contains several scenarios, with reference change and load variations evaluated for each controller are presented.

Повний текст джерелаInnan ett kreditbeslut kan fattas måste en kreditbedömning utföras och utfallet av denna beror på hur mycket och pålitlig information om företaget som kreditbedömaren har. Beroende på hur bankerna bearbetar den information man har är också en påverkande effekt på hur utfallet kommer att bli. Kreditgivare använder sig utav flera källor i sitt sökande och tolkande av information om det kreditsökande företaget där kreditgivarens sociala nätverk är en av dessa källor. Syftet med denna uppsats var att göra en kvalitativ undersökning för att förklara betydelsen av kreditbedömarens sociala nätverk då han/hon i en liten respektive stor stad samlar in information beträffande utlåning till små och medelstora företag. Undersökningen bestod av två personliga intervjuer och två telefonintervjuer som har utförts på Handelsbankens kontor i Falkenberg och Malmö City. Utifrån vår teori har vi skapat en sammanfattande modell som vi sedan har omarbetat efter det att vi samlat in och analyserat vår empiri. Det samlade resultatet av vår teoretiska och empiriska undersökning visar att en kreditbedömare i en liten stad utnyttjar sitt sociala nätverk i hög utsträckning i syfte att samla in information till kreditbedömningsprocessen. Detta i jämförelse med en stor stad där det sociala nätverket tenderar att inte utnyttjas alls. Undersökningen visar även att det sociala nätverket har betydelse för att generera personinformation som sedan används i kreditbedömningsprocessen samt ge lokal-, marknads- och branschinformation. Vi har även konstaterat att det finns olikheter i vilka utlåningstekniker en kreditbedömare i en liten respektive stor stad lägger störst vikt på.

Increasing energy demand, rising oil prices, and environmental concerns have forced attention to alternative energy sources that are environmentally friendly and independent of fossil fuels. Renewable energy sources (RES) have become an attractive alternative to the traditional energy sources for electric power generation. However, one of the main challenges of RES adaption arises when connecting RES to the electric grid. Voltage source inverters (VSIs), typically, connect RES to the electric grid. Similar to any engineering system, detailed dynamic models of the VSIs are needed for design and analysis purposes. However, due to the non-linearity of VSIs, development of dynamic models that can accurately describe their behavior is a complex task. In this thesis, a detailed averaged-state-space model of the two-level three-phase space vector pulse width modulation VSI and its companion LCL filter is derived. Because VSIs can operate under stand-alone and grid-tied modes, two models were derived for each case. In the derived models, the VSI modulation index m and phase angle ϕ are initially considered constant. In practice, however, these parameters are considered the main control parameters. To model these parameters as control inputs, small-signal models of the VSI under stand-alone and grid-tied modes were derived. To verify the accuracy of the developed large-signal and small-signal models, Matlab/Simulink simulations were carried out. The simulation results were compared against the models results. Moreover, the models were verified through lab experiments. The developed models can be used as design and analysis tools. In addition, the developed models can be used as fast and efficient simulation tools for system studies, when the modeling of switching transients is not needed. Nowadays, the number of VSIs connected to the electric grid is growing exponentially. The amount of time and computation needed to simulate VSIs using simulation software packages can be significantly decreased by the use of the developed models.

Повний текст джерелаThe Ipê Felpudo (Zeyhera tuberculosa (Vell) Bur) is a native and pioneer species, which possesses a high silvicultural potencial. It has been threatened of extinguishing due the intense predatory exraction of the Brazilian forestry exploitation. The elimination of the complex forestry ecosystem for agricultural, farming, lumber and industrial activities has induced to the drastic redutions of its genetic base. Plantation density is one of the most important factor or is the most important factor has a great importance for the development of the trees under technological, sivicultural and economic aspects. It influences in the morphological and trees growth. The excellent plantation density is the one that will concur for the biggest volume of the product and its quality. Forest modeling initiates through the inventory of permanent plots that suffer remeasures, therefore, forests are biological systems that are always changing and requires a projection of theese changes, in order to permit executinge management adjustments in this ecosystem. This decisions are based on information of the current and future situations of the stand. The purposes of this work are: to analyze an experiment with 6 different plantation densities; to define a growth model for this species, with stand and climatic variables, collected in the Experimental Station of Linhares, Espírito Santo.

Повний текст джерелаThis study covers the implementation of fire departments in an urban platform in two parts. The purpose of first part is to examine how the urban platform can help developing the operation of fire departments and how this can contribute to a smart city. This is studied through interviews with different fire departments in the region of Mälardalen, Sweden, and an authority responsible for improving the society’s capabilities of managing emergencies. A number of areas within the fire departments, which an urban platform would improve, have been identified. Literature regarding smart cities have been combined with the empirical findings to discuss how the implementation of fire departments in an urban platform can contribute to a smart city. The purpose of the second part is to provide an example of how a fire department can be divided and modeled for an implementation in a potential urban platform. More precisely, the fire department Mälardalens brand- och räddningsförbund is investigated and modeled for an implementation in ABB’s control system 800xA. The result is three different structures that serve as the foundation for the model and a future implementation in an urban platform. In this part, it is also concluded that a necessary step to ensure an effective model is to relate the modelling to the greater context of a city.
