Estudo comparativo entre dois processos construtivos sob o ponto de vista de sua influência na formação do fluxo de caixa de empreendimentos imobiliários habitacionais
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnologico. Programa de Pós-graduação em Engenharia CivilEste trabalho faz a investigação das questões ligadas às finanças de um empreendimento habitacional, definindo como problemática de estudo, buscando investigar se o processo construtivo adotado interfere no fluxo de caixa durante o ciclo de produção. Objetiva-se verificar os ingressos e os desembolsos financeiros de um empreendimento imobiliário habitacional e retirar dados e conclusões, visando auxiliar na investigação da viabilidade econômico-financeira do sistema construtivo que aplica a alvenaria estrutural com blocos de concreto. A definição de uma hipótese parte do princípio de que a tecnologia construtiva pode interferir no fluxo de caixa de um empreendimento habitacional. Uma atenção especial é dada ao desenvolvimento do fluxo de caixa e a importância de tê-lo como uma ferramenta para o auxílio à definição das estratégias e gestão de empresas. A metodologia utilizada envolve a revisão da literatura em obras pertinentes ao tema e o estudo do fluxo de caixa de um empreendimento localizado no município de Umuarama/PR. Como resultado, obteve-se a resposta de que o fluxo de desembolsos financeiros do processo construtivo em alvenaria estrutural não é muito diferente do processo construtivo em concreto armado com fechamento em tijolos cerâmicos furados
Improved Exact Algorithms for Mildly Sparse Instances of Max SAT
No full textWe present improved exponential time exact algorithms for Max SAT. Our algorithms run in time of the form O(2^{(1-mu(c))n}) for instances with n variables and m=cn clauses. In this setting, there are three incomparable currently best algorithms: a deterministic exponential space algorithm with mu(c)=1/O(c * log(c)) due to Dantsin and Wolpert [SAT 2006], a randomized polynomial space algorithm with mu(c)=1/O(c * log^3(c)) and a deterministic polynomial space algorithm with mu(c)=1/O(c^2 * log^2(c)) due to Sakai, Seto and Tamaki [Theory Comput. Syst., 2015]. Our first result is a deterministic polynomial space algorithm with mu(c)=1/O(c * log(c)) that achieves the previous best time complexity without exponential space or randomization. Furthermore, this algorithm can handle instances with exponentially large weights and hard constraints. The previous algorithms and our deterministic polynomial space algorithm run super-polynomially faster than 2^n only if m=O(n^2).
Our second results are deterministic exponential space algorithms for Max SAT with mu(c)=1/O((c * log(c))^{2/3}) and for Max 3-SAT with mu(c)=1/O(c^{1/2}) that run super-polynomially faster than 2^n when m=o(n^{5/2}/log^{5/2}(n)) and m=o(n^3/log^2(n)) respectively
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Affleck-Dine baryogenesis in a string model
No full textEntropy production by a dilaton decay is studied in the model where the dilaton acquires potential via gaugino condensation in the hidden gauge group. Its effect on the Affleck-Dine baryogenesis is investigated. It is shown that the baryon asymmetry produced by this mechanism with the higher-dimensional terms is diluted by the dilaton decay and can be regulated to the observed value
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Inflation in uplifted supergravities
No full textWe present a model of slow roll inflation in the context of effective supergravities arising from string theories. The uplifting of the potential (to generate de Sitter or Minkowski vacua) is provided by the D-term associated with an anomalous U(1), in a fully consistent and gauge invariant formulation. We develop a minimal working model which incorporates eternal topological inflation and complies with observational constraints, avoiding the usual obstacles to implementing successful inflation (the ? problem and the initial condition problem among others)
