Abstract The decisions and personal preferences of the designer are vital for all aspects and stages of the design. To elaborate, the designer has the central role in creation, development, detailing and construction of the built forms. Also, the scientific/engineering evaluations of the design models are carried out under the directions and decisions of the designer. The paper explores the con...

the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

in this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.the device has been designed on the basis of an optimization procedure with the objective tomaximize the energy dissipated in the device. the response of a 3d frame equipped with thedevice and subjected to 7...

This paper also appears in the Proceedings of the Tenth International Conference on Artificial Intelligence. Milan. Italy. August 1987. In recent years knowledge-based techniques like explanation-based learning. qualitative reasoning and case-based reasoning have been gaining considerable popularity in Al. Such knowledge-based methods face two difficult problems: (1) the performance of the syst...

The customer is the core element of business based on current market situation, even for industrial equipment which customers’ requirements are now very various. It means that the inside processes of the manufacturer should adjust to customer’s requirements: the company must be very flexible among other properties. The challenge is that the flexibility comes from the management of the knowledge...

The development of systems comprising of hardware and software components has been a complex and demanding task. To handle the informational and architectural complexity inherent to these systems novel development approaches supported by powerful tools are taken. In this paper we present an approach that is based on Uml and the concepts of platform-based design, modeldriven architecture, and co...

Agent-based systems that are composed of simple locally interacting agents but which demonstrate complex group behavior o er several advantages over traditional multi-agent systems. A well-designed complex agent-based systems is an e cient, robust, adaptive and stable system. It has very low communication and computational requirements, meaning that there are virtually no constraints on the sys...

This report presents a design method for decision rules called ARD+. It is an extension of a previously proposed ARD method. In ARD+ the emphasis is put on the gradual refinement of the conceptual model of a knowledge-based system described with attributes. A practical algorithm providing a transition from the ARD+ design to rule design is introduced. Using ARD+ and the algorithm it is possible...

In this paper, we carry out a detailed analysis of a fuzzy version of Reid’s classical multiple hypothesis tracking (MHT) algorithm. Our fuzzy version is based on well-known fuzzy feedback systems, but the fact that the system we describe is specialized for likelihood discrimination makes this study particularly novel. We discuss several techniques for rule activation. One of them, namely, the ...

Model generation has emerged as a key task in engineering design and analysis. AI research in this area has focused on model based reasoning emphasising qualitative models in attempting to automate this process. In this paper, we propose that this work on the use of model based reasoning in model generation would benefit from the inclusion of case-based reasoning (CBR) techniques. We argue that...
