Texto completoThe use of point contacts has made the Passivated Emitter and Rear Cell design one of the most efficient monocrystalline-silicon photovoltaic cell designs in production. The main feature of such solar cell is that the rear surface is partially contacted by periodic openings in a dielectric film that provides surface passivation. However, a trade-off between ohmic losses and surface recombination is found. Due to the technology used to locally open the contacts in the passivation layer, the distance between neighboring contacts is on the order of hundreds of microns, introducing a significant series resistance.In this work, I explore the possibility and potential advantages of using nanoscale contact openings with a pitch between 300 nm to 10 µm. Analytic and numerical simulations done during the course of this thesis have shown that such nanoscale contacts would result in negligible ohmic losses while still keeping the surface recombination velocity Seff,rear at an acceptable level, as long as the recombination velocity at the contact (Scont) is in the range from 103-105 cm/s. To achieve such contacts in a potentially cost-reducing way, my experimental work has focused on the use of polystyrene nanospheres as a sacrificial mask.The thesis is therefore divided into three sections. The first section develops and explores processes to enable the formation of such contacts using various nanosphere dispersion, thin-film deposition, and layer etching processes. The second section describes a test device using a thin-film amorphous silicon NIP diode to explore the electrical properties of the point contacts. Finally, the third section considers the application of such point contacts on crystalline silicon by exploring localized doping through the nanoholes formed.In the first section, I have explored using polystyrene nanoparticles (NPs) as a patterning mask. The first two tested NPs deposition techniques (spray-coating, spin-coating) give poorly controlled distributions of nanospheres on the surface, but with very low values of coverage. The third tested NPs deposition technique (floating transfer technique) provided a closely-packed monolayer of NPs on the surface; this process was more repeatable but necessitated an additional O2 plasma step to reduce the coverage area of the sphere. This was performed using matrix distributed electron cyclotron resonance (MD-ECR) in order to etch the NPs by performing a detailed study.The NPs have been used in two ways; by using them as a direct deposition mask or by depositing a secondary etching mask layer on top of them.In the second section of this thesis, I have tested the nanoholes as electrical point-contacts in thin-film a-Si:H devices. For low-diffusion length technologies such as thin-film silicon, the distance between contacts must be in the order of few hundred nanometers. Using spin coated 100 nm NPs of polystyrene as a sacrificial deposition mask, I could form randomly spaced contacts with an average spacing of a few hundred nanometers. A set of NIP a-Si:H solar cells, using RF-PECVD, have been deposited on the back reflector substrates formed with metallic layers covered with dielectrics having nanoholes. Their electrical characteristics were compared to the same cells done with and without a complete dielectric layer. These structures allowed me to verify that good electrical contact through the nanoholes was possible, but no enhanced performance was observed.In the third section of this thesis, I investigate the use of such nanoholes in crystalline silicon technology by the formation of passivated contacts through the nanoholes. Boron doping by both thermal diffusion and ion implantation techniques were investigated. A thermally grown oxide layer with holes was used as the doping barrier. These samples were characterized, after removing the oxide layer, by secondary electron microscopy (SEM) and conductive probe atomic force microscopy (CP-AFM)

Texto completoWith the exponentially growing amount of data, sampling remains the most relevant method to learn about populations. Sometimes, larger sample size is needed to generate more precise results and to exclude the possibility of missing key information. The problem lies in the fact that sampling large number may be a principal reason of wasting time.In this thesis, our aim is to build bridges between applications of statistics and k-Determinantal Point Process(k-DPP) which is defined through a matrix kernel. We have proposed different applications for sampling large data sets basing on k-DPP, which is a conditional DPP that models only sets of cardinality k. The goal is to select diverse sets that cover a much greater set of objects in polynomial time. This can be achieved by constructing different Markov chains which have the k-DPPs as their stationary distribution.The first application consists in sampling a subset of species in a phylogenetic tree by avoiding redundancy. By defining the k-DPP via an intersection kernel, the results provide a fast mixing sampler for k-DPP, for which a polynomial bound on the mixing time is presented and depends on the height of the phylogenetic tree.The second application aims to clarify how k-DPPs offer a powerful approach to find a diverse subset of nodes in large connected graph which authorizes getting an outline of different types of information related to the ground set. A polynomial bound on the mixing time of the proposed Markov chain is given where the kernel used here is the Moore-Penrose pseudo-inverse of the normalized Laplacian matrix. The resulting mixing time is attained under certain conditions on the eigenvalues of the Laplacian matrix. The third one purposes to use the fixed cardinality DPP in experimental designs as a tool to study a Latin Hypercube Sampling(LHS) of order n. The key is to propose a DPP kernel that establishes the negative correlations between the selected points and preserve the constraint of the design which is strictly confirmed by the occurrence of each point exactly once in each hyperplane. Then by creating a new Markov chain which has n-DPP as its stationary distribution, we determine the number of steps required to build a LHS with accordance to n-DPP

Texto completoDetta masterexamensarbete behandlar implementeringen av en grafikkortsaccelererad inrepunktsmetod av predictor-corrector-typ för storskalig linjärprogrammering (LP). Implementeringarna testas på LP-problem som uppkommer i finansbranschen, där det finns ett stort behov av allt snabbare LP-lösare. Algoritmen implementeras i C++, MATLAB och CUDA, och dubbelprecision används för numerisk stabilitet. En prestandajämförelse visade att algoritmen kan accelereras 2x till 6x genom att använda ett Nvidia GTX Titan Black jämfört med att bara använda en Intel Xeon E5-2630v2. Mängden minne på grafikkortet begränsar problemstorleken, men alla testade problem som får plats i grafikkortsminnet kunde accelereras.

Texto completoLos modelos de optimización estocástica de dos etapas dan lugar a problemas lineales (PL) muy grandes. Se han ideado varios enfoques para resolverlos de manera eficiente, entre los que se encuentran los métodos de punto interior (MPI). Sin embargo, al usar MPI, las columnas de enlace que están asociados con las decisiones de la primera etapa provocan rellenos excesivos para las soluciones de las ecuaciones normales, lo que hace que el procedimiento sea computacionalmente costoso. Hemos dado un paso adelante en el camino hacia una mejor solución al reformular el PL mediante una técnica de división variable que ha reducido significativamente el tiempo de solución. Este trabajo presenta un MPI especializado que primero aplica la división de variables y luego explota la estructura de la formulación determinista equivalente del problema estocástico. El MPI especializado trabaja con un algoritmo que combina la factorización Cholesky y gradientes conjugados precondicionados para resolver las ecuaciones normales al calcular la dirección de Newton para problemas de optimización estocástica en los que las variables de las primeras etapas son lo suficientemente grandes. Nuestro enfoque especializado supera al MPI estándar. Este trabajo proporciona los resultados computacionales de dos problemas estocásticos de la literatura: (1) un sistema de cadena de suministro y (2) expansión de capacidad en un sistema eléctrico. Se utilizaron formulaciones tanto lineales como cuadráticas para obtener instancias de hasta 39 millones de variables y seis millones de restricciones. Cuando se utiliza en estas aplicaciones, los resultados computacionales muestran que nuestro procedimiento es más eficiente que las implementaciones de PI alternativas de última generación (por ejemplo, CPLEX) y otros métodos especializados para la optimización estocástica.

Texto completoThe Soil, Vegetation, and Snow (SVS) land surface model has been recently developed at Environment and Climate Change Canada (ECCC) for operational numerical weather prediction (NWP) and hydrological forecasting. The main goal of this study is to evaluate the ability of SVS, in offline point-scale mode, to simulate different processes when compared to in-situ observations. The study is divided in two parts: (1) an evaluation of land-surface processes occuring on snow-free conditions, and (2) and evaluation of the snow accumulation and melting processes. In the first part, surface heat fluxes and soil moisture were evaluated under arid, mediterranean, and tropical climates at six selected sites of the FLUXNET network having between 4 and 12 years of data. In the second part, the main characteristics of the snow cover are examined at ten well-instrumented sites having between 8 and 21 years under alpine, maritime and taiga climates from ESM-SnowMIP network. Results of the first part show SVS’s realistic simulations of latent heat flux (NSE = 0.58 on average), sensible heat flux (NSE = 0.70 on average), and net radiation (NSE = 0.97 on average). Soil heat flux is reasonably well simulated for the arid sites and one mediterranean site, and poorly simulated for the tropical sites. On the other hand, surface soil moisture was reasonably well simulated at the arid (NSE = 0.30 on average) and mediterranean sites (NSE = 0.42 on average) and poorly simulated at the tropical sites (NSE = - 16.05 on average). SVS performance was comparable to simulations of the Canadian Land Surface Scheme (CLASS) not only for energy fluxes and soil moisture, but more specific processes such as evapotranspiration and water balance. Results of the second part show that SVS is able to realistically reproduce the main characteristics of the snow cover at these sites. Based on the results, a clear distinction between simulations at open and forest sites can be made. SVS is able to simulate well snow water equivalent, density and snow depth at open sites (NSE = 0.64, 0.75 and 0.59, respectively), but exhibits lower performances over forest sites (NSE = - 0.40, 0.15 and 0.56, respectively), which is attributed mainly to the limitations of the compaction scheme and the absence of a snow interception scheme. Evaluations over early, mid and end winter periods revealed a tendency to decrease SVS’s ability to simulate SWE, density and snow depth during end winter. At open sites, SVS’ snow surface temperatures are well represented (RMSE = 3.00_C on average), but exhibited a cold bias (PBias = - 1.6% on average), which was due to a poor representation of the surface energy balance under stable conditions at nighttime. Albedo showed a reasonable representation (RMSE = 0.07 on average), but a tendency to overestimate end winter albedo (bias = 0.04 over end winter), due to the slow decreasing rate during long melting periods. Finally, sensitivity tests to the snow melting process suggest the use of surface snow temperature instead of the average temperature when computing the melting rate. This would provide the improvement of the SWE simulations, with exception of two open and one forest sites. Sensitivity tests to partition of precipitation allows to identify a linear transition of air temperature between 0 and 1_C as the best choice in the absence of observed or more sophisticated partitions

is certainly one of the greatest challanges for today. Apart from possible applications, the solution may also shed light or at least give some idea on how, actually, the biological vision works. Many problems faced en route to successful algorithms require finding corresponding tokens in different views, which is termed the correspondence problem. For instance, given two images of the same scene from different views, if the camera positions and their internal parameters are known, it is possible to obtain the 3-Dimensional coordinates of a point in space, relative to the cameras, if the same point may be located in both images. Interestingly, the camera positions and internal parameters may be extracted solely from the images if a sufficient number of corresponding tokens can be found. In this sense, two subproblems, as the choice of the tokens and how to match these tokens, are examined. Due to the arbitrariness of the image pairs, invariant schemes for extracting and matching interest points, which were taken as the tokens to be matched, are utilised. In order to appreciate the ideas of the mentioned schemes, topics as scale-space, rotational and affine invariants are introduced. The geometry of the problem is briefly reviewed and the epipolar constraint is imposed using statistical outlier rejection methods. Despite the satisfactory matching performance of simple correlation-based matching schemes on small-baseline pairs, the simulation results show the improvements when the mentioned invariants are used on the cases for which they are strictly necessary.

In this research dissertation, the authors examine the antecedents and consequences of online reputation from the customer’s perspective. A structural equation modeling approach is used to test the model based on data from a survey of 1097 French online buyers. The results show the impact of trust, heritage, and website quality on online reputation, as well as how online reputation affects customer commitment, word of mouth, perceived risk, and perceived value. Several implications either in terms of conceptual or managerial insights are then discussed

Texto completoVatten, och i synnerhet rent vatten är livsavgörande för människor och har en grundlig hälsoeffekt med en förmåga att reducera hälsoåkommor. Paradoxalt nog är vatten samtidigt ett transportmedium för ämnen som orsakar sjukdomar. Vatten kan orsaka sjukdom och illamående både från distributionen av patogena ämnen in i människokroppen men också om intaget av vatten inte är tillräckligt för kroppen, vilket kan leda till uttorkning med stora komplikationer. Idag drabbas vissa områden av katastrofer och olyckor i varierande form. När sådana kriser och katastrofer sker, blir ofta infrastruktur skadad eller förstörd vilket kan medföra att tillgången till rent vatten hotas. Myndigheten för Samhällsskydd och Beredskap (MSB) är en myndighet i Sverige, med uppgift att utveckla social kapacitet för att motverka och hantera nödsituationer, olyckor och kriser. Myndigheten stödjer olika aktörer när en kris eller olycka uppstår, både utomlands och på nationell nivå. Personalen som stödjer på plats i en kriszon arbetar ibland under extrema förhållanden där basala nödvändigheter, som t.ex. tillgången till mat och rent vatten kan vara en bristvara. För att säkerhetsställa att personalen som arbetar på dessa platser kan fortsätta att lösa sin uppgift utan att riskera sitt eget välbefinnande på grund av vattenbrist eller andra vattenrelaterade sjukdomar, kan olika metoder för vattenrening på personlig nivå användas. I den här studien valdes fem olika produkter avsedda för personlig vattenrening ut; klordioxid i tablettform, klordioxid i vätskeform, Katadynflaskan, Lifesaverflaskan och UV-lampan SteriPEN. Dessa produkter utnyttjar olika tekniker för att rena vatten och säkerhetsställa tillgången av rent vatten under utsatta situationer. Målet med den här studien är att skapa en informationsbas som underlag för MSB att använda sig av när de väljer vattenreningsmetod för kommande internationella insatser. Fem produkter utvärderats därför utifrån fyra parametrar; reningskapacitet, handhavande, miljöpåverkan och ekonomisk aspekt. Studien visade att det inte var någon enskild produkt som genomgående var bäst utifrån alla parametrar, de hade alla sina för och nackdelar. Produkten som överlag fick bäst resultat genom studien var SteriPEN men det utifrån att produkten används under tio insatser eller mer. Om en produkt endast ska användas under ett fåtal insatser är klordioxid i vätskeform att föredra. På platser där råvattnet är skarpt kontaminerat kan en kombination av två olika produkter vara aktuell, rekommenderat är att kombinera klordioxid i vätskeform med SteriPEN, draget som slutsats av resultatet av denna studie. Det här är en kvalitativ studie och resultatet grundar sig på litteratur, analysresultat från laboratorietester samt egna mätningar och beräkningar. Faktiska tester i fält är nödvändiga för att vidare utvärdera produkterna. Det viktiga är att produkten faktiskt fungerar praktiskt baserat på förhållandena MSB arbetar under så att hjälparbetare verkligen använder produkten för att rena kontaminerat vatten och inte avstår att använda produkten på grund av att den inte är kompatibel med arbetsförhållandena. Om produkten inte används på grund av den anledningen ska den inte användas i fält då den utsätter hjälparbetarnas hälsa för risk.

Texto completoSubmarine-fan deposits form the largest sediment accumulations on Earth and host significant reservoirs for hydrocarbons. While many studies of ancient fan deposits qualitatively describe lateral architectural variability (e.g., axis-to-fringe, proximal-to-distal), these relationships are rarely quantified. In order to enable comparison of key relationships that control the lateral architecture of submarine depositional environments, I digitized published bed-scale outcrop correlation panels from five different environments (channel, levee, lobe, channel-lobe-transition-zone, basin plain). Measured architectural parameters (bed thickness, bed thinning rates, lateral correlation distance, net-to-gross) provide a quantitative framework to compare facies architecture between environments. The results show that sandstone and/or mudstone bed thickness alone or net-to-gross do not reliably differentiate between environments. However, environments are distinguishable using a combination of thinning rate, bed thickness, and correlation distance. For example, channel deposits generally display thicker sandstone beds than mudstone beds whereas levees display the opposite trend. Lobe deposits display the most variability in all parameters, and thus would be the most difficult to identify in the subsurface. I sub-classified lobe deposits to provide a more detailed analysis into unconfined, semiconfined and confined settings. However, the results for semiconfined lobes indicate that the degree of lobe confinement and subenvironment is not easily interpretable at the outcrop scale. This uncertainty could be partially caused by subjectivity of qualitative interpretations of environment, which demonstrates the need for more quantitative studies of bed-scale heterogeneity. These results can be used to constrain forward stratigraphic models and reservoir models of submarine lobe deposits as well as other submarine depositional environments.
This work is paired with a case study to refine the depositional environment of submarine lobe strata of the Upper Cretaceous Point Loma Formation at Cabrillo National Monument near San Diego, California. These fine-grained turbidites have been interpreted as distal submarine lobe deposits. The strike-oriented, laterally-extensive exposure offers a rare opportunity to observe bed-scale architecture and facies changes in turbidites over 1 km lateral distance. Beds show subtle compensation, likely related to evolving seafloor topography, while lobe elements show drastic compensation. This indicates more hierarchical method of compensational stacking as the degree of bed compensation is small compared to the degree of element compensation. Thinning rates and bed thicknesses are not statistically different between lobe elements. This signifies that the lateral exposure is necessary to distinguish lobe elements and it would be extremely difficult to accurately interpret elements in the subsurface using 1D data (e.g., core). The grain size, mudstone to sandstone bed thicknesses, element/bed compensation, and lack of erosion observed in the Cabrillo National Monument exposures of the Point Loma Formation are most similar to values of semiconfined lobe deposits; hence, I reinterpret that these exposures occupy a more medial position, perhaps with some degree of confinement.
