- Advanced technologies for shoe sole productionPublication . Spahiu, Tatjana; Almeida, Henrique; Ascenso, Rita M. T.; Vitorino, Liliana; Marto, AnabelaAdvanced technologies for modelling and production are an important part in the whole process of product manufacturing. These advancements have changed the way of product development and play an important role in customization. In the footwear industry, as in any other industry, the use of these technologies is widely spread. Footwear comfort is one of the main selection criteria for purchase. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized. As a part of personalization, feet’s plantar pressure maps taken from 1 participant gave a better explanation of weight distribution of each foot. Following, sole personalization according the plantar pressure maps for each foot gives the possibility to obtain the best least material design according to the feet’s pressure while maintaining biomechanical performance.
- Energetic system with biomass and how to mitigate associated problemsPublication . Nabais, Adelino S.; Galvao, Joao R.; Ascenso, Rita M. T.; Leitao, Sergio A.In this work we present a greenhouse case study with a new energy model based on a Biomass energy source, once it is a more profitable and sustainable energy system, but demands special safety measures. Biomass has some dangerous aspects along the process from transport, to storage until its’ use. The paper foccus on safety for equipment operation, storage of biofuels, the design of the facilities and health of the employees, in a context of primary renewable energy source of greenhouses farming systems, for intensive cultivation of flowers and vegetables for human consumption. Similarly, exposure to biologically active material (mustiness and spores) may constitute a danger to the health of those involved in handling biomass. These properties and their use determine safety conditions in handling and storage. This energy model is constituted with several proposals, both technological and energy alternatives/renewable energy, to meet the needs of electric power and heat, with the objective of increasing the competitiveness in agricultural greenhouses, in the management, financial and environmental aspects. The model was developed with the purpose of improving efficiency and sustainability, with the inclusion of sensors that allow controlling the various components of a greenhouse, with the perspective of a quick distribution in the market, increasing the economic benefits and supported on efficient and intelligent management systems energy.
