There are number of software environment available to conduct lighting simulations to support researchers and designers. This paper compares and analyses performance of four lighting simulation programs (AGI32, DIALux, RADIANCE and RELux), which are dedicated to provide physically accurate lighting calculation. Along with the evaluation of modeling ability and software features two significant ...

The successful introduction of technology into museums and exhibitions is a complex and difficult process. It requires detailed study of both visitor expectations and experiences and a sensitivity to curator and exhibition designer concerns, together with the concerns of architects and interior designers, in the case of newly built spaces. It also requires an understanding of the ergonomics of ...

Abstract The selection of an analogical source is a critical step in the design-by-analogy process. Previous researchers have explored reasons and preferences individual designers or design teams selecting sources. Non-designers, who instead more knowledge other fields, may offer new possibilities for retrieving novel This study focuses on differences sources between collaborative composed nond...

In this paper, we use multiwavelet transforms to perform texture classification on twelve Brodatz textures. To increase the correct classification rate, feature selection is considered. Here we use the coevolutionary algorithm rather than the genetic algorithm (GA) which is widely used in many researches to accomplish the training phase of feature selection. In the classification phase, the mea...

A method of rotation invariant texture classification based on spatial frequency model is developed. Features are derived from the multichannel Gabor filtering method. The classification performance is first tested on a set 1440 samples of 15 Brodatz textures rotated in 12 directions (0 to 165 in steps of 15 degrees). For the 13-class problem reported in [13] we got better classification with o...

An efficient texture representation for unsupervised segmentation is addressed based on the concept of Wold decomposition. Textures are described by the wavelet tuned to various scales and rotations to describe its deterministic component, and by the autogressive model to describe its indeterministic component. The wavelet features and the AR parameters capturing the perceptual properties, "per...

Courtyards are traditionally associated with the Middle East countries, where climate and culture have given shape to a particular type of traditional architecture. The study evaluates environmental social impacts courtyards in an educational building integrated occupant’s interaction behavior. case University Sharjah includes eight different unoccupied for many years, locations around various ...

As new products and systems grow in complexity and embed new technologies, designers face new challenges for adequately pursuing their prototyping activities. Tangible User Interface toolkits provide an easier development environment for rapidly exploring and prototyping functional physical interactive devices. Such toolkits range from friendly toy-like building blocks to advanced wireless micr...

Three studies of creative design in engineering and product design are reported. The studies are of outstanding or exceptional designers and comprise one protocol study and two retrospective case studies. In each case, an example of the designer’s creative approach to a particular design problem is analysed. Comparisons between the three examples are drawn, and there appear to be some striking ...

For all M,N∈P(U) such that M⊂N, we first introduced the definitions of (M,N)-uni-soft ideals and (M,N)-uni-soft interior ideals of an ordered semigroup and studied them. When M=∅ and N=U, we meet the ordinary soft ones. Then we proved that in regular and in intra-regular ordered semigroups the concept of (M,N)-uni-soft ideals and the (M,N)-uni-soft interior ideals coincide. Finally, we introduc...
