In this paper, 3D shape retrieval methodology suited for search in special category of 3D shape is presented. The proposed approach employs a fully unsupervised segmentation algorithm to decompose 3D models into components. Shape distribution vectors describing the resulting components are extracted and together with connectivity relations identify a 3D model. The 3D-shapes we are interested in...

This paper establishes an infrared spectral identification key for five natural resins (shellac, sandarac, mastic, copal and rosin) based on their absorbance band positions. These resins may be identified when used in mixtures, such as furniture finishes, at concentrations as low as 1%. Computer methods of deconvolution and spectral subtraction are used to augment this process. The method was v...

It can be observed an increased concern about the school classrooms, in particular about the study and design of school furniture fitting the students’ needs and anthropometrics characteristics. The main aim of this study was to perform an anthropometric survey, considering the main anthropometric dimensions and, in accordance, to define the dimensions and characteristics of school furniture fo...

–Anthropometric considerations play an important role in improving the efficiency of a person. Anthropometry of users is important in designing the products which suit with the user. Seating furniture plays an important role in making the workplace comfortable and suitable for the users. In the present study the classroom furniture’s of different colleges of Gulbarga were studied and analyzed o...

Many researchers introduced special rooms equipped with sensors, devices, networks, and computers to demonstrate ubiquitous computing environment. However, the cost and time for building such a room is a barrier to the deployment of various ubiquitous applications. We have developed Smart Furniture which instantaneously converts the legacy non-smart space into a Smart Hot-Spot which can provide...

Planing properties of seven Australian plantation-grown eucalypts were evaluated to provide recommendations on how these species should be machined and considered for the manufacture of high quality furniture and furnishings. The surface quality produced for each species was evaluated using eight planing conditions. All species performed well producing equivalent or better results than mature t...

The main objective of this study is to evaluate the impact of school furniture and work surface lighting on the body posture of two public Middle School students from Paraíba (Brazil). The target population included 8th grade groups involving 31 students. Brazilian standards for lighting levels, the CEBRACE standards for furniture measurements and the Postural Assessment Software (SAPO) for the...

One of the most important objectives of the Business Innovation and Virtual Enterprise Environment (BIVEE) project is the management and fostering of innovation and production improvement in small and medium enterprises (SMEs). This short paper presents a brief description of the key factors and the methodology followed during the analysis of the current situation of the companies selected as e...

We prove that finite groups have the same complex character tables iff the group algebras are twisted forms of each other as Drinfel'd quasi-bialgebras or iff there is non-associative bi-Galois algebra over these groups. The interpretations of class-preserving automorphisms and permutation representations with the same character in terms of Drinfel'd algebras are also given.

In Ambient Assisted Living (AAL), the context-dependent adaption of a system to a person’s needs is of particular interest. In the living area, a fine-grained context may not only contain information about the occupancy of certain furniture, but also the posture of a user on the occupied furniture. This information is useful in the application area of home automation, where, for example, a lyin...
