The role of automatic shape and position recognitionin streamlining manufacturing

The main features of most components consist of simple basic functional geometries: planes, cylinders, spheres and cones. Shape and position recognition of these geometries is essential for dimensional characterization of components, and represent an important contribution in the life cycle of the product, concerning in particular the manufacturing and inspection processes of the final product. This work aims to establish an algorithm to automatically recognize such geometries, without operator intervention. Using differential geometry large volumes of data can be treated and the basic functional geometries to be dealt recognized. The original data can be obtained by rapid acquisition methods, such as 3D survey or photography, and then converted into Cartesian coordinates. The satisfaction of intrinsic decision conditions allows different geometries to be fast identified, without operator intervention. Since inspection is generally a time consuming task, this method reduces operator intervention in the process. The algorithm was first tested using geometric data generated in MATLAB and then through a set of data points acquired by measuring with a coordinate measuring machine and a 3D scan on real physical surfaces. Comparison time spent in measuring is presented to show the advantage of the method. The results validated the suitability and potential of the algorithm hereby proposed

Optimal behavior of responsive residential demand considering hybrid phase change materials

Due to communication and technology developments, residential consumers are enabled to participate in����Demand Response Programs (DRPs), control their consumption and decrease their cost by using����Household Energy Management (HEM) systems. On the other hand, capability of energy storage systems����to improve the energy efficiency causes that employing Phase Change Materials (PCM) as thermal storage����systems to be widely addressed in the building applications. In this paper, an operational model of HEM����system considering the incorporation of more than one type of PCM in plastering mortars (hybrid PCM) is����proposed not only to minimize the customer�� s cost in different DRPs but also to guaranty the habitants�� ����satisfaction. Moreover, the proposed model ensures the technical and economic limits of batteries and����electrical appliances. Different case studies indicate that implementation of hybrid PCM in the buildings����can meaningfully affect the operational pattern of HEM systems in different DRPs. The results reveal that����the customer�� s electricity cost can be reduced up to 48% by utilizing the proposed model.

Estrat��gia para a incorpora����o de impactes ambientais, sociais e econ��micos espec��ficos num m��todo de Avalia����o da Sustentabilidade de Edif��cios de Sa��de (HBSA)

The healthcare project design requires a several number of concerns with the satisfaction and well���being of the working team, patient and administrators, has a strong social responsibility and impact on the city. Due to various design requirements, these buildings are not designed and used in a sustainable way, because there are still no effective methods to support designers in this context. Consequently, they do not know what the best criteria to be followed and their managers are not aware of the measuresthatshould be adopted for efficient use. Furthermore, the aim of this study is to present a proposal for a Healthcare Building Sustainability Assessment (HBSA) method adapted for the Portuguese context and considering the work developed so far in the standardization bodies (CEN and ISO). For this, the chosen methodology is analysed and compared the most relevant building sustainability assessment tools in the context of healthcare buildings.����
