1. INTRODUCTION This paper describes the database design knowledge of a computer-assisted database design tool, called the Intelligent Database Design Kit (IDDK): useil to develop database sy&ms. The IDDK knowledge base 1s stored in the form of a database dictionary based on an extended entity-relationship-ataibute model. The database dictionary is central to the knowledge engineering approach ...

This study was designed to investigate the effects of different levels of Tarragon powder on general performance and Anetometric, properties of digestive system of male broiler chickens. 200 one-day-old Ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. Experimental diets were set...

learning rapidly and competently has become a pre-eminent strategy for improving organizational performance in the new knowledge era. improving dynamic learning capability is an exclusive strategy for corporate success in construction industry. thus engineering design firms should implement ol to accomplish a state of readiness for change and develop a competence to respond and identify future ...

this study a novel high performance liquid chromatography for the assay of nystatin in oral and vaginal tablets were optimized and validated using box–behnken experimental design. the method was performed in the isocratic mode on a rp-18 column (30 °c) using a mobile phase consisting of 0.05 m ammonium acetate buffer/ methanol mixture (30:70) and a flow-rate of 1.0 ml/min. the method was valida...

This paper proposes an interactive goal-based method for designing daylit buildings. The lighting simulation tool which supports this process is a hybrid global illumination rendering method which efficiently computes annual daylighting metrics. The goal-based method uses a knowledge base populated using a set of previously completed simulations that quantify the effects of various façade desig...

Motivated by needs of concurrent multi-disciplinary design of a multi-purpose vehicle, a modeling and methodological approach to handling tradeoffs is presented. Each component has uncertain elements and a random performance which is influenced by the performance of other components. The components may require different knowledge bases and models with different mathematical structures, time and...
