ModeL4CEP: Graphical domain-specific modeling languages for CEP domains and event patterns

Complex event processing (CEP) is a cutting-edge technology that allows the analysis and correlation of large volumes of data with the aim of detecting complex and meaningful events through the use of event patterns, as well as permitting the inference of valuable knowledge for end users. Despite the great advantages that CEP can bring to expert or intelligent business systems, it poses a substantial challenge to their users, who are business experts but do not have the necessary knowledge and experience using this technology. The main problem these users have to face is precisely hand-writing the code for event pattern definition, which requires them to implement the conditions to be met to detect relevant situations for the domain in question by using a particular event processing language (EPL). In order to respond to this need, in this paper we propose both a graphical domain-specific modeling language (DSML) for facilitating CEP domain definitions by domain experts, and a graphical DSML for event pattern definition by non-technological users. The proposed languages provide high expressiveness and flexibility and are independent of event patterns and actions’ implementation code. This way, domain experts can define the relevant event types and patterns within their business domain, without having to be experts on EPL programming, nor on other complicated computer science technological issues, beyond an understandable and intuitive graphical definition. Furthermore, with these DSMLs, users will also be able to define the actions to be automatically taken once a pattern is detected in the system. Further benefits of these DSMLs are evaluated and discussed in depth in this paper

Development of an Application for Supervision of Concrete Quality Control

TCC(graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Engenharia de Controle e Automação.A tecnologia alcançou um nível de evolução incessável, permitindo que uma grande quantidade de dados possa ser compartilhada e facilitando uma cooperação global, o que incentiva o desenvolvimento de projetos das mais variadas áreas. Com uma estrutura online solidificada, projetos de serviços e produtos baseados na rede web começam a surgir e dominar o mercado. A Jungsoft é uma empresa que desenvolve softwares e possui um projeto de automação para centrais de concreto chamado Kartrak, no qual o autor pôde cooperar e aumentar o conhecimento na área de desenvolvimento web. A plataforma Kartrak não possui uma área para supervisionar e controlar os estados iniciais do controle de qualidade do concreto e o presente projeto busca solucionar tal problema. Uma aplicação web moderna chamada Kartrak Laboratory foi proposta para atacar esse problema de supervisão. Devido ao curto espaço de tempo fornecido para desenvolver o projeto e pelo fato do autor não ter experiência prévia na área de programação funcional e desenvolvimento web, o programa foi construído em cima da plataforma de automação Kartrak. Uma vantagem é que a manutenção do aplicativo será facilitada devido à mesma estrutura estar sendo utilizada. Metodologias ágeis e baseadas em teste foram utilizadas de modo a obter um melhor gerenciamento do tempo. Para atingir um alto nível de qualidade, técnicas de controle de software foram aplicadas durante o desenvolvimento do projeto. As principais funções backend do software, isto é, funcionamento do servidor, foram implementadas, obtendo assim uma aplicação funcional para controlar e registrar todas as etapas do ciclo de vida do corpo de prova. Para garantir um nível de confiança e qualidade, vários testes unitários e de ponta-a-ponta foram desenvolvidos e implementados.Technology has reached a non-stop pace of evolution, allowing data sharing and global cooperation to boost the development of projects from the most vast areas. With a solid online structure, web-based services and products are beginning to emerge and conquer the market. Jungsoft is a company that develops softwares and has a project for the automation of concrete batching plants named Kartrak, in which the author had the opportunity to cooperate and learn. The Kartrak platform doesn’t have a supervision feature to control the early stages of concrete quality and this project targets that problem. Kartrak Laboratory, a modern web-application, was proposed to counteract that problem. Due to short deadline and no previous experience in functional programming and web- development, it was built on top of the already existing Automation platform. An advantage is that maintainability will be enforced since the same structure will be used. Agile and test-driven-development methodologies were pursued in order to have a better management of time. To attain a high level of quality, software quality assurance and control techniques were applied during the application development. The main backend functionalities of the application’s server-side were implemented, thus achieving a working feature to control and register the specimen life cycle. To ascertain a level o confidence and quality, several unit tests and an end-to-end test were designed and implemented

Business improvement through a structured approach to sustainability in the precast concrete flooring industry

Different production and business procurement systems in the precast flooring industry have traditionally been designed to offer products/services with high quality, within shorter delivery times, and with the lowest cost and expense possible. However, these systems do not account for the different environmental impacts arising from its operations. This thesis explores the environmental performance of precast concrete production systems and evaluates how precast organisations can maintain their business cases within a healthy and sustainable approved practice. A Life Cycle Assessment (LCA) study was carried out for five Hollowcore and pre-stressed beams manufacturers (members of the Precast Flooring Federation—PFF) to identify the main environmental impacts arising from the production of precast flooring. It was found that mineral extraction, carbon dioxide emissions, waste disposal, and transportation are the main sources of environmental impact in the sector. [Continues.

建築物生命週期碳排放分析之發展
