Streszczenie:

In the first part, the author discusses the methodological status of interdisciplinary research. Some general issues may be problematized within various disciplines; each of them only examines a certain aspect of the issue. Philosophical categories represent some ideas par excellence, while the terms used by the specific sciences represent models of some of their aspects. The second part recalls the most important problems signaled by engineers and programmers of machines, which are to operate in an external, changing environment, realizing autonomously the objectives set for them. In parts three and four, the author attempts to specify the essential operations that the decision making machine performs. The nature of these operations should be adapted to the requirement that the machine should focus on what is important for the task it performs.

What is the role of aesthetics, everyday aesthetics in particular, in processes of solving social problems? Many if not most social problems arise from and affect our daily lives. As far as these problems contain aesthetic aspects, these typically are also of an everyday kind. In this paper, I address the relations between social problems and everyday aesthetics in five sections. I will start by briefly describing what I mean by social problems. Second, I will outline what solving such problems means. Then, I will move on to defining aesthetics for the purposes of this article. Fourth, I will focus on the main question, the potential role of everyday aesthetics in solving social problems. Lastly, I will drill down a bit deeper into my own experiences in this matter in order to concretize the general points and give examples stemming from my working life.

Streszczenie:

The focus of this paper is on conditional stability estimates for ill-posed inverse problems in partial differential equations. Conditional stability estimates have been obtained in the literature by a couple different methods. In this paper we propose a method called interpolation method, which is based on interpolation in variable Hilbert scales. We are going to work out the theoretical background of this method and show that optimal conditional stability estimates are obtained. The capability of our method is illustrated by a comprehensive collection of different inverse and ill-posed PDE problems containing elliptic and parabolic problems, one source problem and the problem of analytic continuation.

The purpose of the present investigation was to determine what professional and personal problems elementary-school teachers face during their initial years of teaching and how they cope with or solve these problems. Beginning teachers abandon the teaching profession at alarming rates causing grave financial burdens to school divisions, schools, and tax payers. The phenomenon has also contributed to the current teacher shortages in particular subject areas and certain geographic locations. Many teachers who left the profession before their fifth year of professional teaching reported the problems associated with teaching as primary reasons for their exodus. Qualitative in-depth interviews were conducted with six in-service elementary teachers. The interviews were conducted in three parts. All of the six participants were between their fifth and tenth year of teaching, and they all taught at the elementary level. The results indicated that they had problems with (a) personal issues and life experiences, (b) school curricula, (c) children with special needs, (d) differentiation of instruction, (e) discipline, (f) workload and time management, (g) parents, (h), student poverty and studentsâ home issues, (j) relationships with students, (k) teacher training, and (l) administration. The participants coped with these problems by using pattern matching indicating that their own life experiences and backgrounds had significant roles in their problem-solving processes. Recommendations are made for preservice and beginning in-service teachers to focus on their educational experiences and biographical information to recall relevant information that will help them to cope with and solve professional problems.

Streszczenie:

There are numernus social, emotional, and behavioral problems toddlers and preschool children can exhibit. Some of the more common problems reported by parents of young children are daytime behavior problems and sleep disturbances. This study investigated sleep difficulties in toddler and preschool-age children with (n = 31) and without (n = 59) significant behavior problems. Furthermore, the current study investigated the relationship between sleep difficulties and other psychological constructs (i.e., maternal general stress, maternal depression, and parenting stress), which might be related to sleep and behavior problems. Mothers of clinically referred children with behavior problems and nonclinically referred children without behavior problems completed measures regarding their children's sleep and behavior as well as their own general stress, parenting stress, and depressive symptomology. Overall, children with behavior problems showed significantly more sleep difficulties than children without behavior problems. Specifically, when compared to children without behavior problems, children with behavior problems took more time to initiate sleep, showed increased bedtime resistance, had more night wakings, and had shorter sleep durations. Additionally, the results showed that other factors (i.e., maternal depression, family stress, parent-child relationship stress) likely contribute to and/or maintain sleep disturbances in children. The findings from this study suggest a complex relationship between childhood sleep, daytime externalizing behaviors, and maternal health. Potential clinical implications of these findings and future directions for research are discussed.

In this paper we consider the question of uniqueness of positive solutions for Dirichlet problems of the form - Δ u(x)= g(λ,u(x)) in B, u(x) = 0 on ϑB, where A is the Laplace operator, B is the unit ball in RˆN, and A>0. We show that if g(λ,u)=uˆ(N+2)/(N-2) + λ, that is g has "critical growth", then large positive solutions are unique. We also prove uniqueness of large solutions when g(λ,u)=A f(u) with f(0) < 0, f "superlinear" and monotone. We use a number of methods from nonlinear functional analysis such as variational identities, Sturm comparison theorems and methods of order. We also present a regularity result on linear elliptic equation where a coefficient has critical growth.

Aplicações práticas envolvendo estes problemas incluem a alocação de recursos para computadores; o corte de chapas de ferro, de madeira, de vidro, de alumínio, peças em couro, etc.; a estocagem de objetos; e, o carregamento de objetos dentro de contêineres ou caminhões-baú. Nesta tese investigamos problemas de Corte e Empacotamento NP-difíceis, nas suas versões bi- e tridimensionais, considerando diversas restrições práticas impostas a tais, a saber: que permitem a rotação ortogonal dos itens; cujos cortes sejam feitos por uma guilhotina; cujos cortes sejam feitos por uma guilhotina respeitando um número máximo de estágios de corte; cujos cortes sejam não-guilhotinados; cujos itens tenham demanda (não) unitária; cujos recipientes tenham tamanhos diferentes; cujos itens sejam representados por polígonos convexos e não-convexos (formas irregulares); cujo empacotamento respeite critérios de estabilidade para corpos rígidos; cujo empacotamento satisfaça uma dada ordem de descarregamento; e, cujos empacotamentos intermediários e final tenham seu centro de gravidade dentro de uma região considerada "segura". Para estes problemas foram propostos algoritmos baseados em programação dinâmica; modelos de programação inteira; técnicas do tipo branch-and-cut; heurísticas, incluindo as baseadas na técnica de geração de colunas; e, meta-heurísticas como o GRASP. Resultados teóricos também foram obtidos. Provamos uma questão em aberto levantada na literatura sobre cortes não-guilhotinados restritos a um conjunto de pontos. Uma extensiva série de testes computacionais considerando instâncias reais e várias outras geradas de forma aleatória foram realizados com os algoritmos desenvolvidos. Os resultados computacionais, sendo alguns deles comparados com a literatura, comprovam a validade dos algoritmos propostos e a sua aplicabilidade prática para resolver os problemas investigados Abstract: Several versions of Cutting and Packing problems are considered NP-hard and, if we consider that P ¿ NP, we do not have any exact polynomial algorithm for solve them. Practical applications arises for such problems and include: resources allocation for computers; cut of steel, wood, glass, aluminum, etc.; packing of objects; and, loading objects into containers and trucks. In this thesis we investigate Cutting and Packing problems that are NP-hard considering theirs two- and three-dimensional versions, and subject to several practical constraints, that are: that allows the items to be orthogonally rotated; whose cuts are guillotine type; whose cuts are guillotine type and performed in at most k stages; whose cuts are non-guillotine type; whose items have varying and unit demand; whose bins are of variable sizes; whose items are represented by convex and non-convex polygons (irregular shapes); whose packing must satisfy the conditions for static equilibrium of rigid bodies; whose packing must satisfy an order to unloading; and, whose intermediaries and resultant packing have theirs center of gravity inside a safety region; Such cutting and packing problems were solved by dynamic programming algorithms; integer linear programming models; branch-and-cut algorithms; several heuristics, including those ones based on column generation approaches, and metaheuristics like GRASP. Theoretical results were also provided, so a recent open question arised by literature about non-guillotine patterns restricted to a set of points was demonstrated. We performed an extensive series of computational experiments for algorithms developed considering several instances presented in literature and others generated at random. These results, some of them compared with the literature, validate the approaches proposed and suggest their applicability to deal with practical situations involving the problems here investigated Doutorado Doutor em Ciência da Computação

Dissertação de Mestrado apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Psicologia, especialização em Psicologia Clínica e da Saúde. A presente investigação tem como objectivo descrever os problemas de externalização e internalização aliandos à temática da parentalidade. A fundamentação teórica é composta numa primeira fase pela perspectiva da psicologia do desenvolvimento em idade pré-escolar, o contexto, organização e gestão do jardim de infância. Os problemas de conduta e problemas emocionais integram o segundo capítulo e por fim o tema da parentalidade. Na elaboração do estudo empírico e recorrendo à literatura procedeu-se à criação dos seguintes objectivos: (a) perceber se há diferenças na percepção acerca dos comportamentos de internalização e externalização das crianças entre os pais e educadoras (Lopes, 2002; Stivanin, Scheur & Assumpção Jr, 2008); (b) averiguar se existem diferenças entre a escala total de problemas emocionais e a idade das crianças (Oliveira, 2007); (c) entender se há diferenças entre os problemas de internalizção e externalização dependendo do género da criança (Papalia, Olds & Feldman, 2001; Stivanin, Scheuer & Assumpção Jr, 2008); (d) perceber se existem diferenças entre a escala total dos problemas de externalização e a idade das crianças (Oliveira, 2007; Papalia, Olds & Feldman, 2001; Silva, 2008). Foi administrado o questionário SDQ – Questionário de capacidades e dificuldades aos pais e educadoras de oitenta crianças em idade pré-escolar como forma de conhecer as dificuldades e capacidades das crianças de acordo com os dois agentes educativos. Após a análise dos objectivos do estudo pode-se verificar os seguintes resultados: (a) existem diferenças entre a percepção dos pais e educadoras relativamente aos comportamentos das crianças; (b) os problemas de comportamento não variam de forma significativa em função da idade; (c) os problemas de internalização e externalização não variam em função do género; (d) a idade das crianças não influencia os problemas de externalização. Mostra-se importante investir no estudo da problemática dos problemas de conduta e problemas emocionais aliados à parentalidade como forma de melhorar a “tarefa” de educar.--- This research was aimed to describe the problems of internalizing and externalizing combined to the parenting thematic. The theoretical basis is composed initially from the perspective of developmental psychology at preschool age, context, organization and management of the kindergarten. Conduct problems and emotional problems are part of the second chapter and finally, the topic of parenting. In developing the empirical study and using the literature, the following objectives were established: (a) see if there are differences in children’s perception of internalizing and externalizing behaviors between parents and educators (Lopes, 2002; Stivanin, Scheur & Assumpção Jr, 2008); (b) see if there are differences between the full range of emotional problems and the age of children (Oliveira, 2007); (c) understand whether there are differences between the problems of internalizing and externalizing depending on the gender of the child (Papalia, Olds & Feldman, 2001; Stivanin, Scheuer & Assumpção Jr, 2008); (d) understand if there are differences between the overall scale of externalizing problems and the age of children (Oliveira, 2007; Papalia, Olds & Feldman, 2001; Silva, 2008). The SDQ – Strengths and Difficulties was administered to parents and educators of eighty children in preschool as a way to understand the difficulties and abilities according to both school staff. After analyzing the objectives of the study, it is possible to verify the following results: (a) there are differences between the perception of parents and educators in relation to children’s behaviors; (b) behavior problems don’t vary significantly according to age; (c) internalizing and externalizing problems don’t vary according to gender; (d) the child’s age doesn’t influence the problems of externalizing. It reveals important to invest in the studying conduct and emotion problems coupled with parenting as a way to improve the “task” of educating.

Streszczenie:

This research is a case study that examines the strategies that three grade 11 students use to manoeuvre through a series of three combinatorial problems. Grade 11 students were chosen as participants because they have had no formal training in solving this class of math problems. Data includes video recordings of each participant’s problem solving sessions along with each participant’s written work. Through analysis of this data, several themes related to problem solving strategies were identified. First, students tend to rely on algebraic representation and methods as they approach a problem. Second, students use the term “guess and check” to describe any strategy where the steps to a solution are not clearly defined. Thirdly, as students negotiate problems, they tend to search for patterns that will streamline their methods. Fourthly, students approach complicated problems by breaking up the problem into smaller parts. Finally, students who verify their work throughout the problems solving process tend to experience more success than those who do not. From these findings, I suggest that mathematics teachers need to ensure that they are not over-emphasizing algebraic strategies in the classroom. In addition, students need to be given the opportunity to explore various solution strategies to a given problem. Finally, students should be taught how to verify their work, and be encouraged to perform this step throughout the problem solving process. 11

Streszczenie:

The aim of this research is to investigate parallel problem generation for structured optimization problems. The result of this research has produced a novel parallel model generator tool, namely the Parallel Structured Model Generator (PSMG). PSMG adopts the model syntax from SML to attain backward compatibility for the models already written in SML [1]. Unlike the proof-of-concept implementation for SML in [2], PSMG does not depend on AMPL [3]. In this thesis, we firstly explain what a structured problem is using concrete real-world problems modelled in SML. Presenting those example models allows us to exhibit PSMG’s modelling syntax and techniques in detail. PSMG provides an easy to use framework for modelling large scale nested structured problems including multi-stage stochastic problems. PSMG can be used for modelling linear programming (LP), quadratic programming (QP), and nonlinear programming (NLP) problems. The second part of this thesis describes considerable thoughts on logical calling sequence and dependencies in parallel operation and algorithms in PSMG. We explain the design concept for PSMG’s solver interface. The interface follows a solver driven work assignment approach that allows the solver to decide how to distribute problem parts to processors in order to obtain better data locality and load balancing for solving problems in parallel. PSMG adopts a delayed constraint expansion design. This allows the memory allocation for computed entities to only happen on a process when it is necessary. The computed entities can be the set expansions of the indexing expressions associated with the variable, parameter and constraint declarations, or temporary values used for set and parameter constructions. We also illustrate algorithms that are important for delivering efficient implementation of PSMG, such as routines for partitioning constraints according to blocks and automatic differentiation algorithms for evaluating Jacobian and Hessian matrices and their corresponding sparsity partterns. Furthermore, PSMG implements a generic solver interface which can be linked with different structure exploiting optimization solvers such as decomposition or interior point based solvers. The work required for linking with PSMG’s solver interface is also discussed. Finally, we evaluate PSMG’s run-time performance and memory usage by generating structured problems with various sizes. The results from both serial and parallel executions are discussed. The benchmark results show that PSMG achieve good parallel efficiency on up to 96 processes. PSMG distributes memory usage among parallel processors which enables the generation of problems that are too large to be processed on a single node due to memory restriction.

Estamos particularmente interessados no Problema da Mochila Bidimensional: dados um recipiente de tamanho W x H e uma lista de itens bidimensionais, o objetivo é empacotar um subconjunto dos itens de forma a maximizar a área dos itens empacotados. Existem diversos trabalhos que lidam com problemas para itens e recipientes bidimensionais com forma regular (retangular). No entanto, são poucos os estudos que tratam de itens com formas irregulares. Nós propomos algoritmos de empacotamento para itens irregulares em recipientes limitados baseados no uso de No-Fit-Polygon (NFP). Este trabalho apresenta uma heurística GRASP para a versão restrita do Problema da Mochila: uma solução inicial gulosa é gerada e, em seguida, utiliza-se um algoritmo de busca local para melhorar solução atual. Uma estratégia híbrida também foi proposta para versão irrestrita do Problema da Mochila. Ela divide-se em passos de empacotamento de itens irregulares e empacotamento de itens regulares. Testamos os algoritmos com instâncias adaptadas do problema de Strip Packing. O GRASP obteve empacotamentos ótimos para várias instancias testadas e, mesmo para as instâncias em que o algoritmo não obteve resultados ótimos, os empacotamentos obtidos tiveram boa taxa de ocupação, com valores relativamente próximos do ótimo. O tempo de execução do algoritmo foi razoável. Na estratégia híbrida, obtiveram-se empacotamentos bons para a maioria das instâncias, com taxa de ocupação acima de 90% e tempos de execução relativamente baixos Abstract: In this work, we study packing problems dealing with two dimensional irregular items. We are particularly interested in the knapsack version of the problem: given a container with size W x H and a list of two dimensional items, the goal is to pack a subset of items such that the total area of packed items is maximized. There are several works that deal with problems for the case where items and containers have regular shapes (rectangular). However, only a few studies deal with items with irregular shapes. We propose algorithms for packing irregular items in limited containers based on the use of No-Fit-Polygon (NFP). This work presents a GRASP algorithm for the restricted version of the Knapsack Problem: first, a greedy initial solution is generated, then, the local search algorithm is used to improve the current solution. A hybrid strategy has also been proposed for the unrestricted version of the Knapsack Problem. It is divided into steps of packing irregular items and packing regular items. We tested the algorithms using adapted instances for the Strip Packing problem. The GRASP algorithm achieved optimal packings for several of the tested instances, and, even for those that the algorithm did not, the obtained packings had a good occupancy rate, with values relatively close to the optimum. The runtime of the algorithm was reasonable. In the hybrid strategy, we obtained good packings for most of the instances, with occupancy rates above 90% and relatively low execution times Mestrado Teoria da Computação Mestre em Ciência da Computação

Streszczenie:

This report brings together methodological research on stochastic optimisation and work on benchmark and target applications of the ExaQute project, with a focus on unsteady problems. A practical, general method for the optimisation of the conditional value at risk is proposed. Three different optimisation problems are described: an oscillator problem selected as a suitable trial and illustration case; the shape optimisation of an airfoil, chosen as a benchmark application in the project; the shape optimisation of a tall building, which is the challenging target application set for ExaQUte. For each problem, the current developments and results are presented, the application of the proposed method is discussed, and the work to be done until the end of the project is laid out.
