Many problems in nature can be represented as some kind of a satisfiability problem. Several SAT solvers and SMT solvers have been developed in the last decade with the goal of checking the satisfiability of different SAT problems. An all-solution satisfiability modulo theories on top of the Z3 SMT solver is presented that uses the clause blocking algorithm to find all the solution sets of a SAT problem. Then, an incremental All-SMT solver has been presented based on the all-SMT solver which is able to find the satisfiable answers of an incremental SMT problem based on the solution set of the original problem.

Studies focused on developing a semiochemical-based monitoring system for Plutella xylostella (L.) using sex pheromone and Z3-hexenyl acetate. A commercially available pheromone trapping system was used to capture male moths at sites in Alberta in 2007 and 2008. Larval sampling occurred every two weeks after the first males were captured. Male moth capture was predictive of larval density on individual sample dates during the growing season. The predictive capability of pheromone-baited trap capture was not in direct proportion to population density and was inconsistent. Modifications to the trapping system were tested to improve attractiveness. Adding Z3-hexenyl acetate at various doses to pheromone did not improve the attractiveness to males over pheromone alone and did not attract significant numbers of females when tested at various times during the flight season. Trap height and colour did not influence male capture. Pheromone dose and lure type did influence male moth capture in traps. / Plant Science

Tal interação proporciona um ambiente atrativo à atividade humana de exploração dos recursos naturais, resultando em atividades diversificadas. Assim, pode ser caracterizada pela competição por espaços e recursos, por parte de vários atores sociais, e resultando em sérios conflitos. Dentre as várias atividades que ocorrem em zonas costeiras, podemos citar a exploração de recursos pesqueiros como uma atividade de importância econômica e social, que impacta o ambiente, e interage com outras atividades, levando à disputa de espaço, entre outras. Além dos conflitos entre atividades de exploração de diferentes recursos, a atividade pesqueira ainda apresenta conflitos internos, relacionados às diferentes escalas de ação – artesanal, industrial e esportiva. Neste contexto, a pesca artesanal é destacada com o mais elevado potencial para conflitos. Estes conflitos, motivados por diversos fatores retratados neste trabalho, refletem na dinâmica social e econômica das populações costeiras que dependem da pesca. Para o estudo em questão, considerou-se a pesca artesanal de tainha, que vem despertando o interesse da academia, por ser uma das espécies capturadas na região estuarina da Lagoa dos Patos que representa grande importância socioeconômica para os pescadores artesanais da região. Entre os locais em que a pesca artesanal de tainha é desenvolvida, focou-se na Colônia Z3 (colônia de pescadores localizada na Lagoa dos Patos / RS) por se destacar pelo seu elevado número de pescadores e sistema de organização em colônia representativo na região em estudo. Aliado aos conflitos, outro fator analisado é a ação de políticas empregadas pelo governo no setor pesqueiro, pois neste trabalho entende-se que estas políticas públicas podem implicar na geração, ampliação ou minimização dos conflitos provocados pela atividade pesqueira. Assim, buscou-se entender como se estabelece esta relação: políticas públicas agindo sobre conflitos da pesca artesanal, utilizando como local de estudo a Colônia Z3, e como objeto de estudo, a pesca artesanal de tainha. Desta forma, a análise de casos da interação conflitos e políticas públicas vem a somar para o entendimento e argumentação na discussão a respeito da aplicação de políticas públicas no setor pesqueiro. Esta soma contribui no processo de gestão costeira ao analisar as implicações destas relações e sugerir formas de análises e ações sobre a questão dos conflitos pesqueiros. / Coastal Zone can be defined as a dynamic zone where earth and marine environment interact. Such interaction provides an attractive environment to the human activity of exploring natural resources, leading to diversified activities. Therefore, it can be characterized by the competition for spaces and resources by many social actors, having serious conflicts as result. Among several coastal zone activities, there is the exploration of fishing resources as an activity of social and economic importance, which impacts the environment and interacts with other activities, leading to the fight for space, among others. Besides the conflicts between exploration activities of different resources, the fishing activity still shows some inside conflicts related to the different scales of action – artisanal, industrial and sportive. In this context, artisanal fishery is highlighted with the most elevated potential for conflicts. These conflicts, motivated by several factors that will be shown in this study, reflect in the social and economic dynamic of coastal populations that depend on fishery. For this study, it was considered the artisanal fishing of mullet, in which the academy has been showing interest because its one of the species that is captured in the estuarine zone of Patos Lagoon that represents a great socioeconomic importance for the artisanal fishers who live there. Within the places in which artisanal mullet fishery is developed, it focused in Colônia Z3 (fishermen colony located at Patos Lagoon / RS) as it stands out because of the high number of fishermen and a system of colony organization that represents the area under study. Allied to the conflicts, another factor analyzed is the policy actions used by the government in the fishing sector, because in this study it is understood that these public policies can result in the generation, amplification or minimization of the conflicts caused by the fishing activity. Thus, the aim was to understand how this relationship is established: public policies acting over conflicts in artisanal fishing, using Colônia Z3 as a study site and, as a study theme, the artisanal fishing of mullet. So, the analysis of cases of the interaction conflicts and public policies adds to the understanding and argumentation in the discussion about the application of public policies in the fishing sector. This addition contributes in the process of coastal management as it analyses the implications of this relationships and suggests forms of analysis and actions about the subject of fishery conflicts.

Prioritization of software requirements is an important part of the requirements engineering process within the industry of software development. There are many different methods for achieving the most optimal order of software requirements, a list that shows in what order the requirements should be implemented. This degree project utilizes the SMT-based solver Z3 for an interactive prioritization algorithm. Previous studies have shown good results with another SMT-based solver called Yices. With the newer Z3 from Microsoft, the results have been improved further, and the tool is based on Python, and the framework for Z3 is called Z3PY. Experiments have been conducted on a set of different software requirements derived from a project in the healthcare industry and show that the Z3 solution is, in general, improving the requirements prioritization compared to other mentioned solutions in the study that has been tested on the same set of requirements. Results show that the Z3 solution outperformed the other SMT-based solution Yices by 2-4% regarding disagreement and by 3% regarding average distance. The results are significantly improved based on an ANOVA test with a p-value <= 0.05.

A Colônia de Pescadores Z3, localizada às margens da Lagoa dos Patos, na cidade de Pelotas, no Estado do Rio Grande do Sul, Brasil, é um exemplo desta condição imperativa. Uma sociedade de pescadores profissionais artesanais que diante da carência de perspectivas, baixa-estima e desesperança no futuro se vê a frente de uma atividade econômica alternativa focada no seu patrimônio cultural: o turismo. Sendo assim, este trabalho analisa como, diante de uma crise socioeconômica, a Colônia Z3 se apropria, valoriza e passa a proteger suas referências culturais em prol da modificação na ordem dos seus fatos sociais, com base no investimento em turismo. / Dependents historically of powers that manipulate its existence, many local communities obey the normative ones of the tradition, submit itselves ahead of the religiosity and of the climate, are manipulated in its production, submit itselves ahead of traditional productive markets and face economic crises that evolve for serious social problems as the rural exodus, the unemployment, the domestic violence, the streetfight, the consumption of drugs, the suicide and the robberies and murders. The Colônia de Pescadores Z3, located to the edges of the Lagoa dos Patos, in the city of Pelotas Rio Grande do Sul, Brazil, is an example of this imperative condition. An artisan and professional fishing society that ahead of the lack of perspectives, low self-esteem and hopelessness about the future sees itself to the front of an alternative economic activity in focus in its cultural heritage: the tourism. Being thus, this work analyzes how, ahead of a socioeconomic crisis, the Colônia Z3 appropriates itself, values and starts to protect its cultural references in favor of the modification in the order of its social facts, on the basis on the investment in tourism.
