During the Fall of 2009, a pilot study was conducted at the McCormick and Baxter (M&B) Superfund Site to evaluate polydimethylsiloxane (PDMS) profilers as a method for sediment cap performance monitoring. The profilers are shielded solid phase microextraction fibers, silica rods coated with polydimethylsiloxane (PDMS) as the sorbent. The deployment explored whether profiling PDMS could be used as a low impact, highly sensitive, long term monitoring strategy at M&B since the sediment operable unit will be transitioning to the “Operable & Maintenance” phase of Superfund cleanup. To evaluate sediment cap performance, a good understanding of the flux of contaminants from the sediment is required. While surface waters can illustrate this flux, they can also contain contaminants originating from upstream sources. The existing sampling plan at M&B uses a conventional porewater pumping sampling technique that measures both dissolved and particulate fractions. PDMS profilers measure only the freely dissolved fraction which has been shown to be a good indicator of bioavailability. These profilers also have lower detection limits (ng/L) and the ability to measure vertical concentration gradients which can help identify sources and mechanisms of the contamination. Each sampler was analyzed at three depths for the USEPA Priority Pollutant List of 16 polycyclic aromatic hydrocarbons (PAHs). PDMS measurements showed clear vertical profiling with large reductions in PAH concentrations through the sediment cap offshore. Nearshore, uniform concentration profiles were observed indicating increased vertical mixing as a result of tidal smearing. Further, ANOVA and Tukey-Kramer HSD analysis of sample variability revealed PAH concentrations were statistically different at two locations compared to the remainder of the sampling locations- indicating areas requiring closer attention. PDMS profilers were co-located at 13 of the 22 conventional porewater extraction sampling locations. The correlation of PDMS and conventional porewater extraction techniques was limited due to the low detection frequency by conventional porewater extraction methods as a result of the higher detection limits by that method. The correlation was good for light molecular weight PAHs with most measurements of the same order of magnitude and improved with increasing depth (due to the greater number of detections). 72% of the direct comparisons between PDMS-derived and conventionally-derived porewater concentrations were of the same order of magnitude. Any comparison between the two datasets is necessarily limited especially for the higher molecular weight PAHs, however, due to the large number of non-detects in the conventionally collected data. / text

The principal aim of this thesis is to investigate the reception of a text about the Holocaust by pupils of a class in upper secondary school. The text is Fatelessness by Imre Kertész, a text which can be seen as a complex account of the Holocaust. The study tries to shed light on the pupils’ reactions to the text and how the reading influenced their image of the Holocaust. The empirical material derives from a qualitative case study consisting of inquiries, interviews observations and written material from lessons, etc. The theoretical basis for the analysis is focusing on Kathleen McCormick’s concept of repertoires. Both texts and readers have repertoires which can match, mismatch or exist in tension with each other. The analysis focuses on parts of the pupils’ reception in form of the question of genre, style and language, the main character and the image of the Holocaust. The study shows that from an overall perspective the repertoires of the pupils and the text do not match. Instead they often exist in tension. The text has different signals about genre which can be interpreted in several ways. Fatelessness was a challenge for the pupils because of its language with long sentences, many descriptions and untranslated words, mainly German. The strongest reactions were to the main character Gyurka, whom the pupils at first interpreted as cold, naive and optimistic. For many of the pupils this image changed at the reading when they started to view his manners as a way to survive the concentration camps. Even though the text was challenging the images the pupils had about the Holocaust in many ways, their images did not change overall. Despite the fact that the pupils saw the reading of the book mainly as homework they were very engaged in lesson discussions. The study points to the importance of context and discussions about what the pupils bring with them when they encounter the repertoire of the literature of testimony, in this case Holocaust literature. It can be important for teachers to have an understanding of their pupils’ repertoires when they select what literature to read in class. The study also indicates that, as McCormick suggests, tension can be the most productive meeting of the repertoires.

Orientador: José Roberto Sanches Mantovani / Resumo: Neste trabalho, o modelo matemático do problema de fluxo de potência ótimo básico não linear é analisado e manipulado algebricamente para obter um modelo de programação convexa, do tipo cônico de segunda ordem. O conceito de envelopes convexos é apresentado para tratar a não linearidade e não convexidade da restrição trigonométrica inversa que surge ao escrever o modelo de FPO como um modelo cônico. Aplicando duas proposições apresentadas neste trabalho a restrição trigonométrica é resolvida em um pré-processamento por um solver de otimalidade local, neste caso o KNITRO, que enumera todas as possibilidades dos pontos de KKT para obter os envelopes convexos e tornar o modelo de FPO totalmente convexo. O modelo é implementado no AMPL e é resolvido com solvers de otimalidade global com sistemas testes da literatura, nesta tese usam-se os sistemas testes IEEE 14, 30, 57 e 118 barras. Os resultados obtidos são validados comparando-os com resultados fornecidos pelo Matpower, que é um simulador para FPO. Como contribuição desta tese, o modelo convexo de FPO obtido é utilizado como exemplo de aplicações no problema de despacho ótimo de potência ativa e reativa, considerando competições via programação binível. São apresentados dois modelos biníveis e dois modelos uníveis. O modelo iterativo convexo utiliza-se do modelo proposto de FPO convexo e as não linearidades são convexificadas fazendo uso dos envelopes de McCormick. O conceito de dualidade forte é empregado afim de obter um mod...

The concept of convex envelopes is presented to deal with the nonlinearity and nonconvexity of the inverse trigonometric constraint that arises when transforming the nonconvex OPF model into an equivalent conic model. By applying two propositions presented in this work, the trigonometric constraint is solved in a pre-processing stage by a local optimization solver, in this case, the KNITRO solver, which considers all the possibilities of the KKT points to obtain the convex envelopes and find a completely convex OPF model, is used. The model is implemented in AMPL and is solved via global optimization solvers while to show the effectiveness of the model several IEEE systems such as the IEEE 14-, 30-, 57-, and 118-bus systems are used. The obtained results are validated by comparing them with the results provided by Matpower, which is an OPF solver. As a contribution of this thesis, the obtained convex OPF model is used as an application in the active and reactive optimal power dispatch problem, considering competition via bilevel programming. Two bilevel models and two single-level models are presented. The convex iterative model uses the proposed convex OPF model, and the nonlinearities are convexified using McCormick envelopes. The concept of strong duality is employed to obta... (Complete abstract click electronic access below) / Doutor

Solution methodologies for mixed integer bilinear problems (MIBLP) are studied in this dissertation. This problem class is motivated using the pooling problem, a multicommodity network flow problem that typically arises in chemical engineering applications. Stronger than previously known results are provided to compare the strengths of polyhedral relaxations of the pooling problem. A novel single node flow relaxation, defined by a bilinear equality constraint and flow balance, is proposed for the pooling problem. Linear valid inequalities in the original space of variables are derived using a well-known technique called lifting. Mixed integer linear (MILP) formulations are proposed for generating feasible solutions to the pooling problem. Some of these MILP models arise from variable discretizations while others possess a network flow interpretation. The effectiveness of these MILP models is empirically validated on a library of medium and large-scale instances. General MIBLPs, not necessarily pooling problems, are solved using extended MILP reformulations. The reformulation is obtained by writing binary representation for each general integer variable. Facet-defining inequalities are provided for the reformulation of each bilinear term. New valid inequalities are also proposed for bilinear terms with a nontrivial upper bound. The proposed reformulation and cutting planes are compared against a global solver on five different classes of MIBLPs.
