Optimisation of ingot casting wheel design using SPH simulations

Abstract: Performance improvements of a new filling system for aluminium ingot casting resulting from a combination of Smoothed Particle Hydrodynamic (SPH) modelling and pilot scale testing are reported in this paper. The SPH modelling was used as the primary design tool, passing through several design iterations to understand the flow fundamentals and to progressively improve performance. The best concept from the simulation design stage was then refined through a detailed programme of pilot scale testing and a final round of SPH simulation. The results of this development programme will be described, with the new wheel design now able to operate at 50% higher throughput with an expected reduction in the oxide content by about 53% compared to that of the original design.

Development of CAD tool for a design of microwave planar HTS filters

Abstract: Accurate design of microwave planar high-temperature superconducting (HTS) filters is obtained using a computer-aided design tool, which provides simulation of characteristics of the multicoupled transmission-line structures. The quasi-static spectral-domain method is applied. In order to achieve a good correspondence between measured and simulated filter performance, correct models of the microwave propagation characteristics of HTS planar transmission lines have to be used in the simulation procedure. The goal of this paper is to demonstrate that it is possible to design the planar HTS filters that do not need additional trimming after manufacturing. The trimmingless filters can be used in mass production for the next generation of mobile communication systems.

A knowledge-based expert system for earthquake resistant design of reinforced concrete buildings

Abstract: Earthquake engineering includes a wide range of disciplines; these include the analysis and evaluation of earthquake risk and the analysis and design of different types of engineering structures. The most frequently encountered of these many specialists is the analysis and design of building for earthquake excitations. In this case, the design engineer has to deal with concepts and requirements, which are not normally encountered when designing for gravity or wind loads. For example, strength and ductility that are key consideration in earthquake resistant design. Additionally, uncertainties are associated with the determination of the earthquake forces, the stiffness and strength of the different structural elements; the selection of the mathematical models which represent the structure behaviour; and the form and intensity of the design earthquakes. Thus, earthquake resistant design of buildings requires extensive knowledge of the conceptual design of structures, mathematical models and analysis assumptions used in structural analysis, and good element detailing. Computer-based earthquake resistant design assistants are needed to provide practicing engineers with decision support tools and to guide them through earthquake resistant design process. This paper is concerned with the description of a knowledge-based expert system for the earthquake resistant design of reinforced concrete buildings. The system is considered as an interactive analysis/design tool in which the structural engineer is guided from the preliminary earthquake design to the final detailed design including non-linear dynamic analysis. The earthquake design methodology included in this system, which is based on the ductile design approach concept, is briefly described.

Internet aided design (iAD)

Abstract: The invention provides an Internet aided design (iAD), and aims to provide an auxiliary design tool for indoor designers and design fans. The iAD adopts an MVC (Model View Controller) architecture, and is realized by the interactive embedding development of App (Application) and Unity and uses a function manager to uniformly manage function modules, wherein the function modules comprise a decoration design module, a decoration budget module, a construction drawing design module, a client management module and an iAD service module; the decoration design module provides two modes of on-line decoration and off-line decoration; and the construction drawing design module is used for designers to realize wall surface, ground and top surface design, vertical face design, layout design, waterway design, circuit design and construction technology design. The iAD provides a full-course auxiliary means for the quick design, the effect representation, the sharing and the communication of indoor decoration, and constructs a zero-distance interaction space between the designers and users.

NovoFLAP: A ligand-based de novo design approach for the generation of medicinally relevant ideas.

Abstract: NovoFLAP is a computer-aided de novo design tool that generates medicinally relevant ideas for ligand-based projects. The approach combines an evolutionary algorithm (EA-Inventor) with a powerful ligand-based scoring function that uses both molecular shape and pharmacophore features in a multiconformational context (FLAP). We demonstrate that NovoFLAP can generate novel ideas that are not only appealing to design scientists but are also validated by comparison to compounds known to demonstrate activity at the desired biological target. NovoFLAP provides a novel computer-aided design technique that can be used to generate ideas that maintain desirable molecular attributes, such as activity at the primary biological target, while offering opportunities to surmount additional design challenges. Application to the design of the first nonbasic 5HT1B antagonist is presented.
