Contudo, os ganhos da reutilização são mais efetivos quando o reuso é planejado e gerenciado de forma sistemática no contexto de um domínio específico, onde famílias de aplicações compartilham algumas funcionalidades. Neste contexto, uma das formas de se obter um processo de reuso mais sistemático é através do processo de análise de domínio - o processo de identificação de características comuns e variáveis de sistemas em um domínio específico. Este processo é composto por diversas atividades, como definição do escopo, modelagem e documentação do domínio, identificação das restrições, entre outros; e o seu sucesso é muito dependente de quão bem o mesmo é executado. Desta forma, torna-se essencial ter uma ferramenta de suporte para auxiliar a sua execução. Atualmente, existem diversas ferramentas que provêem suporte a análise de domínio, todavia, as mesmas apresentam limitações, como não prover suporte ao processo completo. Assim, este trabalho apresenta os requisitos, a arquitetura e a implementação de uma ferramenta que provê suporte a análise de domínio e que foi focada em resolver as limitações identificadas nas ferramentas existentes. Além disso, esta dissertação descreve o processo e os resultados encontrados nas diversas avaliações que foram executadas em diferentes ambientes com a ferramenta proposta

Uma vez que muitas ontologias são preferivelmente grandes artefatos, para uma adoção em grande escala das mesmas, por exemplo, na Web Semântica, é necessário permitir que desenvolvedores de ontologias possam incluir apenas as entidades e axiomas que são relevantes para a aplicação que estão a desenvolver. Além da reutilização, o uso de modularização de ontologias é útil para muitas outras tarefas, incluindo suporte a queries, raciocínio distribuído, desenvolvimento em grande escala e manutenção de ontologias. Alguns abordagens para modularização têm sido propostas, no entanto nemhuma delas dispõe de uma ferramenta flexível que permita não só definição de módulos, mas também outros tipos de tarefas, como análise sintática e semântica, biblioteca de módulos e uma poderosa ferramenta para seleção de entidades. Esta dissertação propõe um conjunto de ferramentas, chamado ModOnto, para cumprir esses requisitos. Incorpora uma abordagem para modularização de ontologias que herda alguns dos princípios de Engenharia de Software Orientada para Objeto, que são o encapsulamento e o ocultamento de informação

Requirements reuse is based upon the idea that it is possible to reuse requirements from previous software development projects. Requirements reuse leads to efficiency and quality gains in the beginning of the development process. One of the obstacles for requirements reuse is that there is a lack of appropriate tools for it. This work approaches this hinder by identifying properties that are important, that is, that the properties represent something that has so much influence that it should be in a requirements reuse tool. These identified properties may then guide the development when building requirements reuse tools. In order to find the properties this work is conducted as a literature study where both tool-specific and non-tool specific articles were searched in order to elicitate the properties. The work focuses on properties present in both tool-specific and non-tool specific articles. This makes the result more reliable since two different sources have identified them. 18 verified properties were identified through this work.

Wavelength reuse techniques for bidirectional ultra-wide band (UWB) over fiber (UWBoF) networks are presented. The downstream optical signal from the central station (CS) is reused for upstream data transmission with the original data erased at the base station (BS). Two wavelength reuse schemes for the generation of a clear optical carrier at the BS are theoretically analyzed and experimentally demonstrated. In the first scheme, the wavelength reuse is based on phase-modulation to intensity-modulation (PM-IM) conversion and destructive interferencing using a polarization modulator (PolM) and a fiber Bragg grating (FBG). A theoretical analysis is performed which is verified by an experiment. In the second scheme, the wavelength reuse is based on injection locking of a Fabry–Pérot laser diode (FP-LD) and polarization multiplexing. The UWB injection signal contributes to better BERs of both downstream and upstream services and a lower power penalty cause by the wavelength reuse of the whole system than the baseband signal. A bidirectional point-to-point transmission of over a 25-km single-mode fiber (SMF) using a single wavelength from the CS in each scheme is demonstrated.

The current model of complete separation between different industries, buildings and the public, hampers growth and sustainable development within the city. If connections can be identified between several related programmatic elements, can these work together to share and build common resources that benefit all parties involved? The showgrounds in Pretoria West currently exist as a void in the urban fabric, A large part of its infrastructure built for, and is now mostly only used for the annual Jacaranda Show that will now longer take place there. The role of the agricultural show within the city, however, remains a meaningful part of how the public interacts with the agricultural industry. In order to prevent the loss of this relationship and the heritage of the showgrounds, how can a new development around the existing Champion ring retain this role as well as build on the concept of connecting related industries and the public? The main aim of this dissertation is to investigate how architecture can address the interface between the livestock industry, research, education and the public, so that the collaboration between such programs will result in a reduced environmental impact and be of mutual benefit. / Mini Dissertation (MArchProf)--University of Pretoria, 2018. / Architecture / MArch(Prof) / Unrestricted

This project examines the adaptive reuse of a disused nineteenth century textile mill building in Gilbertville, Massachusetts. While the original form and structure of the building type was conducive to maximum production of goods, contemporary uses require different forms. Although other mills in New England have been reused for housing, museums, or professional offices, my goal was to propose a program that related to the building’s original function as a place where people worked. Because the unemployment rate is rising in Massachusetts in 2010, I propose that the mill be reused as a training center where people learn green building techniques that they can use in their jobs. The form of this project is guided by environmental responses to the annual and daily solar paths. Primary among these responses is the conversion of the broad, south-facing masonry wall to a trombe wall system. Similarly, a south-facing light scoop is used on the north side to provide light and heat; shading devices are used throughout the building to prevent overheating.

Ozone is a powerful oxidant and disinfectant used in potable wastewater reuse to destroy specific harmful compounds, including pharmaceuticals, personal care products and endocrine disrupting compounds. Ozonation also increases the biodegradability of recalcitrant organic compounds and inactivates disease-causing microbes. However, bromate, a regulated possible human carcinogen can form when bromide is present due to natural or industrial sources. Pilot-scale testing on wastewater treatment plant effluent with high bromide concentrations showed that the addition of preformed monochloramine could reduce bromate formation by as much as 97%. Monochloramine addition was able to keep concentrations below the U.S. Environmental Protection Agency Maximum Contaminant Level of 10 µg/L while exceeding 3-log or 99.9% virus removal credit. Preforming monochloramine in separate carrier water prior to addition upstream of ozonation eliminated the potential for disinfection byproduct formation when monochloramine is formed in the main water flow. This also allowed for the mechanisms of bromate suppression by monochloramine to be examined without the influence of reactions between chlorine and dissolved organic matter present. This research can help increase the application of ozonation in water reuse. / MS / Ozone is a powerful oxidant and disinfectant used in potable wastewater reuse to destroy specific harmful compounds, including pharmaceuticals, personal care products and endocrine disrupting compounds.
