Design of hybrid components joining zone through sensitivity analysis

Multi-material structures are a trending topic for the industry. With a high application potential, such as lightweight or extended life cycle, different manufacturing technologies are further developed for this intent. One of these technologies is Tailored Forming, a process-chain capable of joining different metals and creating massive hybrid components. In parallel to this development, new challenges rise for design, which has the responsibility of finding an optimal use of this technology and produce higher-performance products. However, this task cannot be solved by conventional engineering approach, since strong manufacturing constraints are involved and a lack of understanding about the joining zone formed between the materials still exists. To fill this gap, the objective of this study is to analyse the influence of the joining zone design over the structure behaviour and establish a suitable design method. For that, a computer-aided environment was constructed and a parametric sensitivity analysis was executed, taking a hybrid shaft as example. At the end, the simulation's results allowed a multi-objective optimisation and were able to generate first design guidelines. © 2019 Design Society. All rights reserved

Mapping Knowledge Flows in ExploratoryWeb Searches

This paper provides an understanding of the knowledge flow in exploratory Web searches. Based on the Design Science Research epistemology, we represented the information-gathering behaviour and uncovered the knowledge flow of Web searchers as a Knowledge-intensive Process (KiP). By mapping searchers' steps and paths during Web searches, representing their search patterns and decision-making process, it was possible to reveal the knowledge flow and infer the resources more likely to be selected to meet the searchers' information needs. With the help of six teachers, we applied the Think-Aloud method in a scenario where they searched for online (educational) resources on the Web. The application of the Think-Aloud method made knowledge-flow processes explicit throughout Web searches. The results can support new strategies for information retrieval systems and be applied to support expertise exchange and innovation

Online Product Search with Focus on Customers\u27 Needs

The success of e-commerce depends on the Information Systems that support it. Currently, the most used approach in e-commerce systems is the faceted search, that requires the customer to be familiar with the technical specification, to find the products that best meet their needs. The aim of this research is to evaluate a novel proposal to improve the online product search. Our solution will automatically map products\u27 features with less technical criteria, which will replace the filters in a faceted search. To achieve this goal, we have adopted a multi-criteria analysis method to rank the result. The proposed solution was evaluated through an empirical experiment with some product categories, using as data set the reviews of experts retrieved from the web. Results showed a strong rank correlation between our solution and the expert reviews, proving its feasibility and effectiveness

Uma Revisão Sistemática sobre Descrição Semântica na Internet das Coisas

A Internet das Coisas (Internet of Things - IOT) está criando um ecossistema de objetos conectados à Internet, porém que são heterogêneos em termos de recursos, características, natureza, protocolos, ações e tecnologias. Neste cenário, a descrição das coisas (Thing Description - TD) mostra-se como uma alternativa para descrever de forma padronizada os objetos da IOT e permitir, entre outras possibilidades, uma melhor interoperabilidade. Visto o crescente interesse de pesquisa e as oportunidades de aplicação da TD, este trabalho apresenta uma revisão sistemática deste tema, visando identificar áreas de aplicação, técnicas, tecnologias e resultados com o uso da descrição das coisas. 324 trabalhos foram identificados, dos quais 46 foram selecionados para análise, os quais foram classificados em seis diferentes áreas

0001/2007 - Personalização: Um Estudo no Contexto de Aprendizagem

Atualmente há uma certa dificuldade na obtenção de informações que realmente atendam às necessidades específicas dos usuários nos sistemas convencionais de busca. No que se refere à personalização em termos de aprendizagem, verifica-se que um dos principais problemas é que os alunos são tratados de maneira uniforme. Neste sentido, a personalização assume um papel importante na medida em que provê mecanismos para tratar cada aluno/usuário em função de suas características, preferências, nível de conhecimento, etc. Este estudo tem como objetivo elucidar algumas questões acerca de personalização, buscando uma ênfase maior em termos de personalização em aprendizagem. Neste sentido, o estudo procura, também, destacar alguns dos principais trabalhos da área

The Play Your Process Method for Business Process-Based Digital Game Design

Serious games have been understood as a useful tool to engage, educate and train individuals in many areas. They are also suitable for the business processes management area where it is expected that business-process-based digital games can bring together players (process actors) to better understand and learn organizational business processes. This paper presents a game design method for the development of serious games which aims to provide business process understanding to players, as well as to allow them to reflect on process challenges and difficulties. The design of serious business process games requires game designers to have business process modeling skills and instructions on how to represent business process elements in the game context. This research was conducted using the Design Science Research Methodology, and addresses the challenge of providing a method for the design of serious business process games. The method receives business process models as input and comprises steps to (i) map business process elements into game design elements, game design and development, and (ii) evaluate games with game designers, process actors, and game players. In order to validate the method, a set of games was built and evaluated with players. The designed games were evaluated as to adequate quality, although fun and entertainment can still be improved, and players´ understanding regarding process increase after games are playe

PYP – Play Your Process: Um Método de Design de Jogos Digitais Baseados em Processos de Negócio

Jogos digitais são frequentemente usados em diversas áreas como ferramentas capa-zes de ensinar algo. Em se tratando especificamente da gestão de processos de negó-cio, existem algumas propostas de uso de jogos digitais para treinamento de pessoal e simulações das etapas de um processo de negócio. Pensando na capacidade de os jogos darem suporte ao ensino e aprendizagem, esta pesquisa argumenta sobre a oportunidade de usar modelos de processo de negócio para o design de jogos digitais. Assim, este relatório técnico visa apresentar e organizar, em detalhes, o método Play Your Process (PYP), o qual é um método de design de jogos digitais baseado em mo-delos de processos de negócio. Este método foi pensando para ser uma ferramenta útil para pessoas que queiram construir jogos digitais para a compreensão de proces-sos, no qual o jogo deva transmitir conhecimentos sobre ele
