Design of an Event Based Messaging System

B2B document handling is moving from paper to electronic networks and electronic domain very rapidly. Moving, handling and transforming large electronic business documents requires a lot from the systems handling them. This paper explores new technologies such as SOA, event-driven systems and ESB and a scalable, event-driven enterprise service bus is created to demonstrate these new approaches to message handling. As an end result, we have a small but fully functional messaging system with several different components. This is the first larger Java-project done in-house, so on the side we developed our own set of best practices of Java development, setting up configurations, tools, code repositories and class naming and much more.

Training system for conceptual design and evaluation for wastewater treatment

Rising population, rapid urbanisation and growing industrialisation have severely stressed water quality and its availability in Malawi. In addition, financial and institutional problems and the expanding agro industry have aggravated this problem. The situation is worsened by depleting water resources and pollution from untreated sewage and industrial effluent. The increasing scarcity of clean water calls for the need for appropriate management of available water resources. There is also demand for a training system for conceptual design and evaluation for wastewater treatment in order to build the capacity for technical service providers and environmental practitioners in the country. It is predicted that Malawi will face a water stress situation by 2025. In the city of Blantyre, this situation is aggravated by the serious pollution threat from the grossly inadequate sewage treatment capacity. This capacity is only 23.5% of the wastewater being generated presently. In addition, limited or non-existent industrial effluent treatment has contributed to the severe water quality degradation. This situation poses a threat to the ecologically fragile and sensitive receiving water courses within the city. This water is used for domestic purposes further downstream. This manuscript outlines the legal and policy framework for wastewater treatment in Malawi. The manuscript also evaluates the existing wastewater treatment systems in Blantyre. This evaluation aims at determining if the effluent levels at the municipal plants conform to existing standards and guidelines and other associated policy and regulatory frameworks. The raw material at all the three municipal plants is sewage. The typical wastewater parameters are Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). The treatment target is BOD5, COD, and TSS reduction. Typical wastewater parameters at the wastewater treatment plant at MDW&S textile and garments factory are BOD5 and COD. The treatment target is to reduce BOD5 and COD. The manuscript further evaluates a design approach of the three municipal wastewater treatment plants in the city and the wastewater treatment plant at Mapeto David Whitehead & Sons (MDW&S) textile and garments factory. This evaluation utilises case-based design and case-based reasoning principles in the ED-WAVE tool to determine if there is potential for the tool in Blantyre. The manuscript finally evaluates the technology selection process for appropriate wastewater treatment systems for the city of Blantyre. The criteria for selection of appropriate wastewater treatment systems are discussed. Decision support tools and the decision tree making process for technology selection are also discussed. Based on the treatment targets and design criteria at the eight cases evaluated in this manuscript in reference to similar cases in the ED-WAVE tool, this work confirms the practical use of case-based design and case-based reasoning principles in the ED-WAVE tool in the design and evaluation of wastewater treatment 6 systems in sub-Sahara Africa, using Blantyre, Malawi, as the case study area. After encountering a new situation, already collected decision scenarios (cases) are invoked and modified in order to arrive at a particular design alternative. What is necessary, however, is to appropriately modify the case arrived at through the Case Study Manager in order to come up with a design appropriate to the local situation taking into account technical, socio-economic and environmental aspects. This work provides a training system for conceptual design and evaluation for wastewater treatment.

Design of Pulsed Electroacoustic Measurement System for Space Charge Characterisation

Pulsed electroacoustic (PEA) method is a commonly used non-destructive technique for investigating space charges. It has been developed since early 1980s. These days there is continuing interest for better understanding of the influence of space charge on the reliability of solid electrical insulation under high electric field. The PEA method is widely used for space charge profiling for its robust and relatively inexpensive features. The PEA technique relies on a voltage impulse used to temporarily disturb the space charge equilibrium in a dielectric. The acoustic wave is generated by charge movement in the sample and detected by means of a piezoelectric film. The spatial distribution of the space charge is contained within the detected signal. The principle of such a system is already well established, and several kinds of setups have been constructed for different measurement needs. This thesis presents the design of a PEA measurement system as a systems engineering project. The operating principle and some recent developments are summarised. The steps of electrical and mechanical design of the instrument are discussed. A common procedure for measuring space charges is explained and applied to verify the functionality of the system. The measurement system is provided as an additional basic research tool for the Corporate Research Centre of ABB (China) Ltd. It can be used to characterise flat samples with thickness of 0.2–0.5 mm under DC stress. The spatial resolution of the measurement is 20 μm.

Design, development and assessment of the Java Intelligent Tutoring System

The "Java Intelligent Tutoring System" (JITS) research project focused on designing, constructing, and determining the effectiveness of an Intelligent Tutoring System for beginner Java programming students at the postsecondary level. The participants in this research were students in the School of Applied Computing and Engineering Sciences at Sheridan College. This research involved consistently gathering input from students and instructors using JITS as it developed. The cyclic process involving designing, developing, testing, and refinement was used for the construction of JITS to ensure that it adequately meets the needs of students and instructors. The second objective in this dissertation determined the effectiveness of learning within this environment. The main findings indicate that JITS is a richly interactive ITS that engages students on Java programming problems. JITS is equipped with a sophisticated personalized feedback mechanism that models and supports each student in his/her learning style. The assessment component involved 2 main quantitative experiments to determine the effectiveness of JITS in terms of student performance. In both experiments it was determined that a statistically significant difference was achieved between the control group and the experimental group (i.e., JITS group). The main effect for Test (i.e., pre- and postiest), F( l , 35) == 119.43,p < .001, was qualified by a Test by Group interaction, F( l , 35) == 4.98,p < .05, and a Test by Time interaction, F( l , 35) == 43.82, p < .001. Similar findings were found for the second experiment; Test by Group interaction revealed F( 1 , 92) == 5.36, p < .025. In both experiments the JITS groups outperformed the corresponding control groups at posttest.

Plan de empresa "Dorcé"

Dorcé es una idea de negocio que responde de manera directa a la necesidad de vestir de las mujeres a través de su innovador sistema operativo “Diseño y confección a tu manera” el cual tiene como objetivo revolucionar la tradicional forma de adquirir prendas de vestir femeninas en la ciudad de Villavicencio. Desde su creación y ejecución, se ha observado una gran aceptación de dicho sistema operativo por parte de los clientes antiguos generando muy buenos resultados económicos partiendo de sus actividades principales, el diseño, la confección y venta de prendas de vestir femeninas. Es por esto que el desarrollo de este trabajo de grado va dirigido a organizar de una manera más administrativa los diferentes procesos que se llevan a cabo dentro de la organización a fin de conseguir incrementar la producción y llegar así a un grupo más amplio de clientes con base en sus necesidades y a las actuales tendencias de la moda. Esta labor tiene como fin, responder y satisfacer a la mujer villavicense en términos de moda, servicio y confección, agregándole un valor adicional en cuanto a menores tiempos de entrega, altos estándares de calidad y exclusividad. Todo lo anterior, en un solo lugar. El sistema operativo (factor diferenciador) de esta idea de negocio consiste en ofrecer a los clientes, diferentes modelos de las partes (cuello, manga, contorno, falda y panty) que componen las prendas que fabrica Dorcé (Blusa, vestido y traje de baño). Con el fin de que el cliente pueda armar la prenda a su gusto teniendo el plus de ir “a la medida”. Dicha prenda de carácter exclusivo, es confeccionada y entregada al cabo de un máximo de 3 días dependiendo de la complejidad que tenga para ser elaborada, garantizándole al cliente no solo la originalidad del diseño de su prenda sino también fabricarla en menor tiempo que la competencia. Es un producto y un servicio innovador que va dirigido a mujeres de quince a setenta años de edad de la ciudad de Villavicencio, mujeres de media y alta sociedad que se caracterizan por su gusto por la moda y la calidad. Una vez se satisfacen las necesidades de nuestros clientes se da lugar a nuevas ventas dentro del grupo social de cada una de ellas, una vez nos refieran de manera positiva con sus amigas y conocidas. Este tipo de publicidad (voz a voz) es la que ha llevado a Dorcé a crecer a través de los años sin perder la exclusividad de su mercado; sin embargo, en la actualidad, la idea de negocio carece de estructura empresarial adecuada, de estrategias que garanticen su crecimiento y sostenibilidad, también carece de recursos financieros inmediatos que faciliten la ampliación y adecuación de la planta de producción y del almacén. Es por ello que las actuales empresarias de esta idea de negocio tienen como objetivo, mediante la elaboración de este plan de empresa, desarrollar, organizar y mejorar las estrategias, acciones, objetivos, alianzas, cambios, inversiones, que se tienen y necesitan para el mejoramiento interno y externo de la compañía. Para el desarrollo de dicho plan, Dorcé cuenta con Doris Blanco, una diseñadora de modas de 25 años de experiencia en el sector textil y confección en la ciudad de Villavicencio, quien está a cargo del área de producción de la empresa, dos estudiantes de Administración de Negocios Internacionales, Fernanda Montes y Juliana Villamizar, quienes están a cargo de la parte administrativa, comercial y estratégica de la empresa. De igual forma cuenta con el conocimiento del mercado textil y de confección, así mismo amplias relaciones que se han venido fortaleciendo a través del tiempo con los diferentes proveedores de materia prima en la ciudad, maquinaria y materia prima inicial, cerca de sesenta mujeres que se han vinculado a la empresa como clientes fieles a la idea de negocio promocionándolo de manera positiva día a día, así como también el interés, empuje y compromiso por parte de las involucradas en desarrollar, ejecutar y sostener esta idea de negocio como proyecto de vida.
