A case-based approach to planar linkage design
We describe a method to store and retrieve design cases of four-bar linkages. The method abstracts relevant features from the planar curve that characterizes each linkage design, and records these features at several levels of abstraction. This allows to use a fast multi-level retrieval procedure, that successively eliminates inappropriate cases at each level. The retrieval incorporates toleran...
متن کاملA Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
متن کاملPhenomenological approach to the design process based on perceptions (Case Study Shiraz School for the Blind)
Researches and evaluation of the different ideas on the subject of design, the complexity of this field of science and providing perspective theories in this regard lead the experts to look deeper into the subject, thus creating descriptive opinions in this regard. Taking another look at this issue will lead the designers and architects to consider a targeted effort based on the knowledge as ...
متن کاملA Theoretical Approach to Molecular Design: Planar-Tetracoordinate Carbon
A number of novel hydrocarbon cage systems have been designed and characterized using ab initio molecular orbital calculations at the MP2 and B3-LYP levels. In particular, equilibrium structures for five families of molecules, hemialkaplanes, hemispiroalkaplanes, alkaplanes, spiroalkaplanes and dimethanospiroalkaplanes, have been examined in detail with the aim of designing a saturated hydrocar...
متن کاملFragment-based Binding Efficiency Indices in Bioactive Molecular Design: A Computational Approach to BACE-1 Inhibitors
One of the most important targets in Alzheimer disease is Beta site amyloid precursor protein cleaving enzyme-1 (BACE-1). It is a membrane associated protein and is one of the main enzymes responsible for amyloid β (Aβ) production. Up to now, a considerable number of peptidic and non-peptidic inhibitors of BACE-1 have been developed. Recently, small molecule BACE-1 inhibitors have attracted the...
