▼ With worldwide petroleum resources dwindling and greenhouse gas emissions rising, it is urgent to find renewable replacements for petroleum-derived products. A biomass-derived chemical with high potential as a platform intermediate, γ-valerolactone (GVL) can be readily synthesized by hydrogenation of levulinic acid (LA), itself a common biomass intermediate, using supported Ru catalysts. Overall, vapor phase hydrogenation is more energy sensitive as the higher boiling point of LA (~245°C) and requires a high energy input, comparable to liquid phase hydrogenation, which is more economical. To date the literature on many novel biomass conversion processes such as the hydrogenation of LA to GVL has focused more on the process and less on the catalyst. Therefore, many efforts have been given to develop the novel catalysts, to improve the activity, selectivity and stability for the hydrogenation of LA to GVL. The purpose of this dissertation is to systematically study the effects of nanoparticle size, support, dopants including alkali metal, alkaline earth metal and Rhenium on ruthenium activity on the levulinic acid (LA) hydrogenation to γ- valeroactone (GVL), which could provides insight into optimizing commercial process for hydrogenation of LA to GVL by studying the structure-function relationships. The reactions were evaluated in a stainless steel EZE-Seal batch reactor with 100ml capacity. The first part of this work is to derive fundamental synthesis-structure-function relationships of Ru catalysts for LA hydrogenation using carbon and alumina supported Ru nanoparticles which have been synthesized in a rational, repeatable, scalable way. We have demonstrated that the method of strong electrostatic adsorption (SEA) yields well dispersed, homogeneously distributed Ru particles with tight particle size distributions over both types of supports. SEA synthesis of well dispersed nanoparticles results in higher activity than commercial Ru catalysts with higher Ru loadings. The dramatic, beneficial effect of potassium doping is reported for the first time. The carbon support yields higher inherent activity than alumina. Activity as a function of particle size appears to go through a maximum at about 1.5 nm for both supports and suggests hydrogenation of LA is structure sensitive on Ru particle size. Catalyst deactivation after 24 h occurs to significant extents (8 – 58%) mainly by nanoparticle sintering, but also by minor amounts of K loss in K-doped samples. Secondly, a systematic study with alkali and alkaline earth elements was carried out to verify the origin of the promotion effect and the optimal ratio of dopant to Ru. Series of catalysts were prepared by impregnating various amounts of alkali onto 2% Ru/alumina (itself synthesized with high Ru dispersion by strong electrostatic adsorption) and were evaluated for LA hydrogenation. With the ratio of dopant to Ru constant, strong promotional effects of alkali and alkaline earth metals on the activity in terms of turnover frequency (TOF) were observed… Advisors/Committee Members: John R.

▼

A reconfiguração de redes de distribuição de energia elétrica consiste em alterar sua topologia por meio de manobras de chaves nos circuitos primários. Trata-se de um problema de otimização combinatória, onde normalmente os objetivos são a minimização de perdas ativas e/ou número de manobras realizadas, atendendo as restrições como isolamento de faltas, balanceamento de cargas entre os alimentadores e melhoria dos níveis de tensão. As dificuldades na modelagem e na resolução exata de problemas envolvendo a reconfiguração de redes de distribuição advém do tamanho dos sistemas reais, representados por um número elevado de chaves e alimentadores e ainda pela natureza combinatorial do problema. Para tratar essas questões, diversas modelagens e técnicas computacionais têm sido desenvolvidas, em particular heurísticas de melhoramento que através de uma solução factível, otimiza os resultados reduzindo o espaço de busca, até encontrar uma nova solução com melhor função objetivo. Neste sentido, são propostas duas formulações matemáticas descrevendo novas restrições a fim de melhorar a descrição do problema. A primeira, uma formulação mais simplificada, considera apenas a parte ativa das instâncias; na segunda um modelo completo é descrito otimizando parte das restrições do primeiro modelo e considerando também a parte reativa das instâncias. Duas heurísticas também são adaptadas pela primeira vez para o problema de reconfiguração de redes, pois a heurística de melhoramento Fix-and-Optmize é configurada de duas formas diferentes, determinando seus principais parâmetros através de uma análise de sensibilidade. Os resultados dos dois modelos propostos e também das heurísticas adaptadas para 13 sistemas de referência são descritos e comparados com outros métodos da literatura. Para verificar a eficiência e robustez dos métodos e heurísticas desenvolvidos, replicações são propostas de dois sistemas de referência, 9 replicações do sistema de 72 barras e 4 replicações do sistema de 10560 barras. Seus resultados bem como o desempenho dos métodos são descritos e avaliados.

A reconfiguration of electricity distribution networks consists in altering a topology of the networks by means of key maneuvers in the primary circuits. It is a problem of combinatorial optimization, where the objectives are a minimization of active losses and/or number of maneuvers performed, taking into account constraints such as fault isolation, load balance between feeders and improvement of voltage levels. As difficulties in modeling and in the exact resolution of problems involving a reconfiguration of distribution networks come from the size of the real systems, represented by a large number of switches and feeders, and also by the combinatorial nature of the problem. To address these issues, several models and computational techniques have been developed, in particular heuristics of improvement that through a feasible solution, improves results by reducing the search space, until finding a new solution with better objective function. In this…

With the advances in the membrane technology, there is an ongoing quest to determine the best optimal configuration for an adopted treatment as well as it’s polishing to achieve cumulative sustainability for the treatment process. Henceforth, this thesis report is an evaluation to devise a membrane filtration process for investigating the possibility of treating pre-sedimented municipal wastewater with ceramic ultrafiltration, optimizing the membrane as a pre-treatment for reverse osmosis as an overall strategy for recovering wastewater. Methods and various technological trends pertaining to membrane filtration of municipal wastewater were researched and documented, Interestingly the five most influential factors governing the membrane performance are identified: 1) Back pulsing Frequency 2) VRF 3) Run Time 4) Cross-Flow Rate 5) Trans Membrane Pressure (TMP). To get a thorough and holistic overview of parametric influence design of experiment (DOE) is devised to find the influence of above-given factors on outcoming responses as COD Reduction (%), Membrane Flux and Turbidity reduction (%). 16+3 DOE factorial tests are executed at Hammarby Sjöstadsverk, Joint Research Facility of IVL Swedish Environmental Research Institute & KTH Royal Institute of Technology on pilot plant WASLA incorporating an ATECH GmBh 20kDa, Type 7/6 Ultrafiltration membrane module where Factorial experiments resulted in a maximum value of flux of 274 LMH, 88.75% reduction of COD and 99.94% reduction of Turbidity. Moreover, response values obtained from the Results of factorial experiments are fed in MODDE, generating a model using PLS Regression, The model summary presented predictivity and reproducibility trends w.r.t responses used. Furthermore, COD resulted in the worst fit followed by Turbidity, and the best fit was observed for Membrane Flux where model fit represented the ability to predict the respective parameter. Optimization tool is utilised to simulate a case scenario where the Membrane flux response is maximized to a high value of 300 LMH and correspondingly 211.885 LMH value is recorded, Furthermore factor influence is identified to be TMP> VRF> Cross Flow >BP Frequency >Runtime. Overall COD reductions are found out to be heavily influenced by the varying incoming feed therefore it is hard to analyze their interactions and predict their subsequent reduction behavior. Back pulsing overall was found out to be another non-influential factor colluding with results throughout the experimental duration with very little or no effect on the permeate water quality.

Datahantering är en aspekt av systemlösningar som inte ska försummas. Svarstider är en lika viktig aspekt i den moderna onlinetjänsten. När molntjänster har nått en popularitet högre än någonsin är det viktigt att veta hur man använder dem effektivt för att kunna få bästa resultat. Kunden, Axis Communications, utvecklar för närvarande en IoT-plattform (Internet of Things) som tros leverera ytterligare mjukvarufunktionalitet och information i realtid till slutanvändaren. Ett moment i denna tjänst är händelsehantering och behandling. Detta kräver att händelser tas emot och bearbetas med hjälp av AWS-komponenter innan de skickas vidare. I denna rapport har vi jämfört prestandan mellan att berika en händelseström med information via externa tjänster och att berika samma händelseström via lokala tjänster. För att bestämma vilka lösningar som ger en snabbare responstid för vår klient, Axis Communications, har vi utvecklat en ny prototyp. Utvecklingsprocessen som vi har valt gör det möjligt att iterera och utvärdera prototypen under utvecklingsprocessen. Utvärderingen bör endast användas som riktlinje vid bedömning av händelsehanteringstjänster, eftersom antalet parametrar kan skilja sig och ge ändrade resultat. Resultaten visar att vår metod för denna lösningen presterade upp till 5,16 gånger bättre än den externa tjänsten. Molntjänsten presterade även bättre under hög belastning tack vare skalbarheten hos AWS Lambda.

Data processing is an aspect of system solutions which cannot be neglected. Response times is an equally important aspect in the modern online service. With cloud services reaching an all-time peak in popularity, it is important to know how to use them efficiently by providing the best results. The client, Axis Communications, is currently developing an IoT (Internet of Things) platform which is thought to deliver further software functionality and information in real-time to the end user. One of the elements of this service is event handling and processing. It requires events to be received and processed using AWS components before sending them through. In this thesis we aim to compare the performance between decorating an event stream using external services to decorating the same event stream with local services. In order to determine which of the solutions offer a better result for our client, we had to develop a new prototype of said solution. The process of development makes it possible to iterate and evaluate the prototype during the time of development. The evaluation should only be used as a guideline when considering event handling services as the number of parameters may differ and yield altered results. The results prove that our method for this solution had up to 5,16 times faster response time. The cloud-based solution also performed better when under heavy load by processing all of the requests simoultanously due to the scaling of AWS Lambda.

▼ The increasing penetration of distributed generation (DG) in power distribution systems presents technical and economic benefits as well as integration challenges to utility engineers. Governments are beginning to acknowledge DG as an economically viable alternative to deferring investment at generation, transmission and distribution levels, meeting demand growth and improving distribution network performance and security. DG technology is rapidly maturing in Ontario due to government economic incentives promoting connection, specifically, the Ontario’s Feed-In-Tariff (FIT) Program. Optimal sizing and siting of DG is well researched, traditionally studying the technical impact on distribution system such as real power loss reduction and voltage profile improvement. Equally common objectives studied are the economics of DG installation which are useful for the developer when deciding when and where to install. Although DG represents a “non-wires” solution to network asset reinforcement, the direct economic benefit to the host utility from promoting DG uptake is not fully understood by utility planners and asset managers. Some DG based asset reinforcement deferral work has been performed in the UK and Italy but is mainly at the transmission level and is not part of an overall strategy that could be applied by a utility. This research presents a comprehensive three stage technique: optimal siting, optimal sizing and financial evaluation of cost savings over a defined planning period to quantify the economic benefit to a Local Distribution Company (LDC) of solar photovoltaic (PV) DG connections on an actual distribution feeder. Optimal sites for PV DG are determined by applying the power loss sensitivity factor method to the test feeder. The objective functions used to determine cost savings consist of loss minimization, asset investment deferral, and peak demand reduction to identify an optimal DG penetration limit. Furthermore, a utility planner can identify an optimal DG penetration limit, encourage uptake at preferred locations that would benefit the LDC, and use the positive impact of DG at existing locations as part of an asset management strategy to prioritize and schedule future asset reinforcement upgrades.

▼ A simple model that includes energy and carbon dioxide (CO2) emissions in the economics of machining is proposed, which has been published in the highly respected and cited journal, Annals of CIRP (International Academy for Production Engineering). This is a timely analysis in current government discussions on a proposed carbon tax or a carbon cap and trade regime and greater energy efficiency. The new cost model is based on life cycle analysis methodology for the initial part production. An illustrative example is given showing that the cheapest electrical grid should not be chosen, if it also has the highest CO2 emissions. Accurate pricing is important, because the more expensive product was highly dependent on the carbon price. A comprehensive review of machining economic models is covered. However, there is a dearth of actual machining data in the literature. This work includes studies in milling and single point incremental forming (SPIF) which can be used by other manufacturing engineers in their machining economic model development. The first milling study involved simple straight cuts. In general, as feed rate (FD) increased (increasing the material removal rate, MRR), the energy consumed decreased as process time decreased. In contrast, as spindle speed (N) increased, energy consumed increased, since more power is drawn by the motor, without a process time reduction. Given the inverse power relationship observed for the time, energy, process CO2 and cost against MRR, the recommended parameters were the same at the highest FD and lowest N permissible. In the second milling study with constant N for a more complex part (sprocket), similar relationships were observed. However, for sprockets made at constant chip load (allowing FD and N to change together), there were varying prescribed MRRs for time, energy, process CO2 and cost minimization. The SPIF studies showed a similar relationship to the constant N milling, and, that results for a simple part can be extrapolated to improve efficiency in more complex parts. Finally, although the energy and carbon costs represented a small contribution to the final cost, their significance increased for higher efficiency parameters or user conditions, e.g. low labour rate.

O consumo energético verificado nas refinarias petrolíferas é muito elevado, sendo as fornalhas os equipamentos que mais contribuem para esse consumo. Neste estudo foi efetuada uma avaliação e otimização energética às fornalhas da Fábrica de Aromáticos da Refinaria de Matosinhos. Numa primeira fase foi efetuado um levantamento exaustivo de dados de todas as correntes de entrada e saída dos equipamentos para posteriormente efetuar os balanços de massa e energia a cada uma das fornalhas. Os dados relativos ao levantamento compreenderam dois períodos de funcionamento distintos da unidade fabril, o período de funcionamento normal e o período relativo ao arranque. O período de funcionamento normal foi relativo ao ano de 2012 entre os meses de janeiro a setembro, por sua vez o período de arranque foi de dezembro de 2012 a março de 2013. Na segunda fase foram realizados os balanços de massa e energia quantificando todas as correntes de entrada e saída das fornalhas em termos mássicos e energéticos permitindo o cálculo do rendimento térmico das fornalhas para avaliar a sua performance. A avaliação energética permitiu concluir que existe um consumo maior de energia proveniente da combustão do Fuel Gás do que do Fuel Óleo, tanto no período de funcionamento normal como no arranque. As fornalhas H0101, H0301 e a H0471 possuem os consumos mais elevados, sendo responsáveis por mais de 70% do consumo da Fábrica de Aromáticos. Na terceira fase foram enunciadas duas medidas para a otimização energética das três fornalhas mais consumidoras de energia, a limpeza mensal e o uso exclusivo de Fuel Gás como combustível. As poupanças energéticas obtidas para uma limpeza mensal foram de 0,3% na fornalha H0101, 0,7% na fornalha H0301 e uma poupança de 0,9 % na fornalha H0471. Para o uso exclusivo de Fuel Gás obteve-se uma poupança de 0,9% na fornalha H0101 e uma poupança de 1,3% nas fornalhas H0301 e H0471. A análise económica efetuada à sugestão de alteração do combustível mostra que os custos de operação sofrerão um aumento anual de 621 679 €. Apesar do aumento dos custos, a redução na emissão de 24% de dióxido de carbono, poderá justificar este aumento na despesa.

The energy consumption in oil refineries is very high and the fired heaters are the equipment that contribute most to this consumption. This report was carried out to evaluate and optimize the fired heaters of the aromatics plant oil refinery in Matosinhos. Initially, an exhaustive evaluation of all of the equipments input and output streams, performed. This data was used to calculate the mass and energy balance for each of the fired heaters. The data for the evaluation comprised two distinct periods of operation of the plant, the normal run period and the startup period. The normal run period was from January to September 2012 and the startup period was from December 2012 to March 2013. In the second phase, mass and energy balances were determined to quantify all input and output streams, in order to calculate the efficiency of the fired heaters and evaluate their thermal…

▼ Multi-level optimization stems from the need to tackle complex problems involving multiple decision makers. Two-level optimization, referred as ``Bi-level optimization'', occurs when two decision makers only control part of the decision variables but impact each other (e.g., objective value, feasibility). Bi-level problems are sequential by nature and can be represented as nested optimization problems in which one problem (the ``upper-level'') is constrained by another one (the ``lower-level''). The nested structure is a real obstacle that can be highly time consuming when the lower-level is \mathcal{NP}-hard. Consequently, classical nested optimization should be avoided. Some surrogate-based approaches have been proposed to approximate the lower-level objective value function (or variables) to reduce the number of times the lower-level is globally optimized. Unfortunately, such a methodology is not applicable for large-scale and combinatorial bi-level problems. After a deep study of theoretical properties and a survey of the existing applications being bi-level by nature, problems which can benefit from a bi-level reformulation are investigated. A first contribution of this work has been to propose a novel bi-level clustering approach. Extending the well-know ``uncapacitated k-median problem'', it has been shown that clustering can be easily modeled as a two-level optimization problem using decomposition techniques. The resulting two-level problem is then turned into a bi-level problem offering the possibility to combine distance metrics in a hierarchical manner. The novel bi-level clustering problem has a very interesting property that enable us to tackle it with classical nested approaches. Indeed, its lower-level problem can be solved in polynomial time. In cooperation with the Luxembourg Centre for Systems Biomedicine (LCSB), this new clustering model has been applied on real datasets such as disease maps (e.g. Parkinson, Alzheimer). Using a novel hybrid and parallel genetic algorithm as optimization approach, the results obtained after a campaign of experiments have the ability to produce new knowledge compared to classical clustering techniques combining distance metrics in a classical manner. The previous bi-level clustering model has the advantage that the lower-level can be solved in polynomial time although the global problem is by definition \mathcal{NP}-hard. Therefore, next investigations have been undertaken to tackle more general bi-level problems in which the lower-level problem does not present any specific advantageous properties. Since the lower-level problem can be very expensive to solve, the focus has been turned to surrogate-based approaches and hyper-parameter optimization techniques with the aim of approximating the lower-level problem and reduce the number of global lower-level optimizations. Adapting the well-know bayesian optimization algorithm to solve general bi-level problems, the expensive lower-level optimizations have been dramatically reduced while obtaining very… Advisors/Committee Members: Fonds National de la Recherche - FnR [sponsor].

▼ Vid beslut om gemensam säljorganisation tvärs divisionsgränser, har jag kommit fram till att sex aspekter måste tas i beaktande på följande sätt: 1) Att upprätta teknikorganisationer, vilka kan vara produktledningar, som stöd för säljkåren i tekniska frågor. Dessa ska kunna ge support till säljare ute hos kunder, vilket är speciellt viktigt vid nykundsbearbetning och större projekt, ta fram offerter, och allmänt fungera som en teknisk back up i olika tekniska frågor. 2) Produktutbildning för säljkåren, för att ge den tillräcklig teknisk kompetens, så att den kan hantera frågeställningar mellan kund och teknikorganisation. 3) Hantera mål- och rollkonflikter, genom strukturerat arbetssätt, med mål och planer, tydlighet med vad som förväntas av olika parter, samt lämpligt kompensationssystem. Med hänsyn till det som framkommit i intervjuer är detta den enskilt viktigaste punkten att nogsamt beakta, speciellt då den kan riskera att underskattas. 4) Skulle kulturella motsättningar uppstå eller tänkas uppstå bör det proaktivt hanteras, t.ex. genom att man arbetar med gemensamma grundvärderingar och skapar medvetenhet om kulturella skillnader. 5) Organisationen måste bygga på kundfokus och team baserat arbetssätt, då det är många som måste samarbeta över organisationsgränser och tillsammans kunna erbjuda lösningar som stärker kundens konkurrenskraft. Det kommer också ställa andra krav på säljare, och deras utbildning, vilket innebär mer fokus på att kunna hantera relationer med kunder och andra aktörer, och mindre på specifik teknik. Denna aspekt kommer bli allt viktigare i framtiden för att kunna skapa framgångsrika säljorganisationer. Att följa utvecklingstrenderna, bör med andra ord kunna underlätta för gemensam säljorganisation. 6) En mer pragmatisk form av gemensam sälj-organisation tvärs divisioner, där det finns tydliga synergier mellan divisionerna, är klart att föredra. Det bör där finnas synergier, som t.ex. samma marknadssegment eller kunder.

▼ In the past decade deep learning has revolutionized many areas of computer science.Deep learning computations mostly consist of expensive linear algebra kernels defined over a mixture of large sparse and dense tensors. From the early days of deep learning framework development, researchers realized the potential for applying compiler optimizations to accelerate neural networks. As deep learning continues to grow in popularity the diversity of models also continues to grow. Due to the early success of deep learning in computer vision, early deep learning systems were were focused on static, feed-forward networks processing fixed sized images. First-generation deep learning compilers have also been similarly overfit for static model compilation, with strong assumptions of static control-flow, static tensor dimensions and no complex data structures. A focus on static models has created challenges for deep learning practitioners, as dynamic models introduce input-dependent graph topology, violating key invariants of existing systems and invalidating optimizations designed for purely static data flow graphs. This lack of support has manifested as series of ad-hoc extensions to both frameworks, deep learning runtimes and compilers. Choosing to ignore dynamic behaviors has allowed deep learning compilers to make significant strides in optimizing common deep learning workloads, but existing techniques miss increasing generality without sacrificing performance. This dissertation in particular focuses on an under served, yet important problem: the representation, optimization, differentiation and execution of dynamic neural networks.In this thesis I propose generalizing overspecialized compilation techniques applied to static dataflow graphs, the predominant programming model of deep learning, to fully dynamic neural networks. These generalizations are powered by a simple insight: dynamic neural networks are just programs which manipulate tensors. The challenge is constructing a representation that captures this generality in a principled manner, while not sacrificing state-of-the-art performance or the programming model. In particular, the contributions include: an intermediate representation which can represent dynamic behaviors, a new automatic differentiation technique for dynamic neural networks, a set of general optimizations which work on all programs, as well as specialized dynamic optimizations, an efficient runtime for dynamic neural networks. The efforts of my thesis now exists in Apache TVM, a deep learning compiler framework.Apache TVM is deployed in production at multiple leading companies including Amazon, Facebook, and Microsoft and is a critical piece of the technology stack at OctoML a company I co-founded around the TVM project. One notable impact is its use in Amazon Alexa, Amazon's AI assistant which executes on a variety of devices such as ``smart speakers'' which include digital assistants. Amazon engineers used Relay to optimize Alexa’s wake word model, executed each time a user interacts with Alexa. Advisors/Committee Members: Tatlock, Zachary (advisor).

A geração de quadros de horários escolares é um problema clássico de otimização que tem sido largamente estudado devido a sua importâncias prática e teórica. O problema consiste em alocar um conjunto de aulas entre professor-turma em períodos de tempo pré-determinados, satisfazendo diferentes tipos de requisitos. Devido a natureza combinatória do problema, a resolução de instâncias médias e grandes torna-se uma tarefa desafiadora. Quando recursos são escassos, mesmo uma solução factível pode ser difícil de ser encontrada. Várias técnicas tem sido propostas na literatura científica para resolver o problema de geração de quadros de horários escolares, no entanto, métodos robustos ainda não existem. Visto que o uso de métodos exatos, como por exemplo, técnicas de programação matemática, não podem ser utilizados na prática, para resolver instâncias grandes da realidade, meta-heurísticas e meta-heurísticas híbridas são usadas com frequência como abordagens de resolução. Nesta pequisa, são desenvolvidas técnicas que combinam programação matemática e heurísticas, denominadas mateheurísticas, para resolver de maneira eficiente e robusta algumas variações de problemas de geração de quadros de horários escolares. Embora neste trabalho sejam abordados problemas encontrados no contexto de instituições brasileiras, os métodos propostos também podem ser aplicados em problemas similares oriundo de outros países.

The school timetabling is a classic optimization problem that has been extensively studied due to its practical and theoretical importance. It consists in scheduling a set of class-teacher meetings in a prefixed period of time, satisfying requirements of different types. Given the combinatorial nature of this problem, solving medium and large instances of timetabling to optimality is a challenging task. When resources are tight, it is often difficult to find even a feasible solution. Several techniques have been developed in the scientific literature to tackle the high school timetabling problem, however, robust solvers do not exist yet. Since the use of exact methods, such as mathematical programming techniques, is considered impracticable to solve large real world instances, metaheuristics and hybrid metaheuristics are the most used solution approaches. In this research we develop techniques that combine mathematical programming and heuristics, so-called matheuristics, to solve efficiently and in a robust way some variants of the high school timetabling problem. Although we pay special attention to problems arising in Brazilian institutions, the proposed methods can also be applied to problems from different countries.
