Architecture is a form of self-expression and one the most influential arts, as it expresses human interaction with society surrounding environment. The development in architecture since beginning twentieth century appeared both content, which made subject interest number fashion designers, possible to take advantage technical progress design clothes that achieve aesthetic aspects through use c...

Cylindrical gears have a wide range of applications in the manufacturing industry because of their advantages. And it is of great significance to study the design techniques and optimization methods of cylindrical gears. In this paper, parametric primary design of single-stage helical gear drive is discussed. And parametric design of the cylindrical gear is carried out by using optimized design...

We propose a new parametric macromodeling technique for complex electromagnetic (EM) systems described by scattering parameters, which are parameterized by multiple design variables such as layout or substrate feature. The proposed technique is based on an efficient and reliable combination of rational identification, a procedure to find scaling and frequency shifting system coefficients, and p...

The powering requirement of a land yacht is one of the most important aspects of its design. In this respect the wind tunnel testing is an effective design tool. In fact, changing the parameters of the vehicle and testing the changes in the wind tunnel will give us a better understanding of the most efficient vehicle, and yet it is time consuming, expensive, and has inherent scaling errors. Ano...

Asynchronous Transfer Mode (ATM) has emerged as a backbone for high-speed broadband communications networks. In this paper we present ATM switch design starting from a parametric high-level model, validating the model using a combination of formal veriication and simulation. We used a combination of theorem proving and model checking to discover bugs in the high-level model that was presumed co...

We discuss the design of interactive, internet based benchmarking using parametric (statistical) as well as non-parametric (DEA) models. The user receives benchmarks and improvement potentials. The user is also given the possibility to search different efficiency frontiers and hereby to explore alternative improvement strategies. An implementation of both a parametric and a non parametric model...

ABSTRACT This paper presents a mathematical and graphical formalism for modeling computational engineering design processes, particularly to enhance variant product design in industries. The proposed modeling formalism provides a methodology for transforming a textual problem statement into a mathematical, parametric model. The explicit representation of the designer’s solution strategy is also...

In this paper, existence and solution of the feedforward plus feedback control law for model reference control of a class of second-order dynamic systems are investigated. A necessary and sufficient condition for the existence of the controllers is established. Based on a result of parametric eigenstructure assignment in second-order dynamic systems, general complete parametric expressions for ...
