Integrating Innovation and Technology: A Case Study
Marques, Pedro Carmona; Silva, Arlindo; Henriques, ElsaThis paper explores a successful case of a product-service system (PSS). To meet the requirements of the client's needs and the existence of many technologies, business models and innovations involved in its conception and development, a conceptual framework of the ideation process is purposed to explain how the company met the requirements of such technical complexity, adding value to customers, stakeholders, ...
A new risk prioritization model for failure mode and effects analysis
Anes, Vitor; Henriques, Elsa; de Freitas, M.; Reis, LuisFailure modes and effects analysis is a framework that has been widely used to improve reliability by prioritizing failures modes using the so‐called risk priority number. However, the risk priority number has some problems frequently pointed out in literature, namely its non‐injectivity, non‐surjectivity, and the impossibility to give weights to risk variables. Despite these disadvantages, the risk priority nu...
Multi-variable prioritization model for risk evaluation scenarios in mechanical...
Anes, Vitor; Henriques, Elsa; Freitas, Sofia de; Reis, LuísRisk prioritization is an important procedure in FMEA methodology where failure modes are prioritized using the so-called risk priority number (RPN), which prioritizes failure modes based in only three risk variables usually, severity, occurrence, and detectability. However, in some risk scenarios, more than three risk variables can improve risk prioritization, but an ease risk prioritization model like RPN for...
Effects of Nintendo Wii® program in dual-task performance in older adults
Rodrigues, Abel; Pinheira, Vítor; Coutinho, António; Leitão, Catarina; Monteiro, Ana; Henriques, ElsaA sedentary lifestyle has a strong impact on the older population; so participation in physical activity is important for enhanced physical and mental function, increasing health and well-being. In the elderly, dual-task activities are severely impaired which is why the Nintendo Wii® may be an important tool to maintain the proper functioning of the physical and mental levels among the elderly. This study sough...
Efeito de um programa de treino com consola Nintendo Wii Fit® na performance de...
Monteiro, Ana; Henriques, Elsa; Pinheira, VítorIntrodução: Um estilo de vida sedentário tem um grande impacto na população idosa, e por isso a participação em atividade física é importante para a função mental e física, aumentando a saúde e o bem-estar. Nos idosos a capacidade de execução de atividades de dupla-tarefa pode tornar-se crítica e a Nintendo Wii Fit pode ser utilizada como uma importante ferramenta que permite praticar exercícios que incluam a d...
Effect of the injection moulding processing conditions on biopolymers final pro...
Teixeira, Pedro; Pontes, A. J.; Henriques, ElsaThis research work intended to study the effect of the main injection moulding parameters in the final properties of biopolymers mouldings. An experimental procedure was carried out in which four biopolymers containing different composition percentages of poly-lactic acid (PLA) and plasticized starch (PLS) were compared with polypropylene (PP). For each material the effect of the processing conditions (mould te...

O eco-design nas PMEs de base industrial : desenvolvimento de uma nova metodologia
Teixeira, Pedro; Henriques, Elsa; Pontes, A. J.Introdução: Uma nova metodologia para a abordagem do Eco-design (ED) nas PMEs de base industrial foi desenvolvida e testada. O principal objectivo do método é permitir que as PMEs com escassos recursos de I&D possam identificar oportunidades decrescimento tendo em conta os princípios do Eco-design (PED) cruciais para o desenvolvimento económico e sustentável.; Synopsis: A new methodology approach to the Eco-Des...
A contribution to the Life Cycle Management Application to mould making business
Peças, Paulo; Henriques, Elsa; Quinas, Pedro; Gomes, Cristina; Pouzada, A. S.; Pontes, A. J.The Life Cycle Management (LCM) concept defines a new wide open type of management. With this concept the managers must see a product in its entire life cycle, regarding typical managerial subjects, environmental issues like air emissions generated, and all massic and energetic streams. With this approach, managers will be able to predict the total cost of a product, the natural resources consumed, the energy s...
