TL;DR: The SCORES-II program as mentioned in this paper is a conceptual-level analysis tool for the performance prediction of liquid propellant rocket engines that can be run on all major computing platforms (e.g., UNIX, PC, Mac).
Abstract: The SCORES-II program is a conceptual-level engineering design and analysis tool for the performance prediction of liquid propellant rocket engines. The tool is written in the C++ programming language and can be compiled and executed on all major computing platforms (e.g. UNIX, PC, Mac). SCORES-II can be executed through a command line/console application or via the ModelCenter © environment with its filewrapper. The Analysis Server © filewrap allows for automated execution and integration with other disciplinary analysis tools. SCORES-II can support a wide variety of engine configurations. In addition to the built-in propellant options, the chemical equilibrium routine is capable of handling any generic fuel and oxidizer combination. Numerous options exist for sizing an engine, including thrust and throat area matching. An 'expert system' of engine efficiencies is also included, allowing for cycle, chemical reaction, injector/combustor, and nozzle influences on performance. The equations used for the performance calculations, equilibrium chemistry model, and engine sizing will be presented and discussed. Chemical equilibrium results obtained from implementing these equations will then be compared with results from another equilibrium code widely used in industry. Performance predictions from SCORES-II will be compared with known performance values for a number of existing engines. Sample results demonstrating SCORES-II's throttled engine analysis will be presented for a notional engine design. The tool's user-interface options will also be discussed. Finally, the paper will include a future work section detailing additional improvements and capabilities planned for future incarnations of SCORES.

TL;DR: In this article, an integrated analysis and design computer program which applies to the partially restrained type of construction has been developed, which is a nonlinear, iterative and interactive-aided tool based on the stiffness method and polynomial connection model.

TL;DR: HMM-Edit (Hypermedia Design Model Editor), a schema editor that supports the conceptual design of Web (and, more generally, hypermedia) applications, is described and compared with the current version of the tool.
Abstract: As online and off-line electronic publishing is increasingly becoming a massive industrial activity, the design of Web applications, and of hypermedia applications in general, needs to become a well-organized and efficient process. If a good design model is the first item on the agenda, then immediately afterwards, design tools become necessary. This paper describes HDM-Edit (Hypermedia Design Model Editor), a schema editor that supports the conceptual design of Web (and, more generally, hypermedia) applications. HDM-Edit is a component of the JWeb system which supports all the phases of Web prototyping development. HDM-Edit can be used on its own, to support the design activity and the production of high-quality design documentation, or in conjunction with other JWeb modules. HDM-Edit promotes design reuse by supporting several navigation patterns as built-in modelling primitives and by allowing designers to derive the schema of a specific application as a set of hyperviews on the design of a family of applications (an application framework). This paper analyses the requirements for a design tool, outlines JWeb, describes HDM-Edit, discusses experiences of use, and finally compares the requirements with the current version of the tool.

TL;DR: A composite syntactic-semantic representation of objects that is particularly suited for creative design in engineering that supports the search for alternative solutions in both domains is presented.
Abstract: The paper presents a composite syntactic-semantic representation of objects that is particularly suited for creative design in engineering. This representation is to a great extent oriented towards visual evaluation. The role of emergence both in art and in engineering design is discussed firstly. It is shown on examples taken from Escher’s prints, Civil Engineering and Mechanical Engineering that the emergence can occur with respect to the shape of the object or to its internal structure or topology. The composite representation supports the search for alternative solutions in both domains. It has been implemented as a design tool including the editor of graph grammars, the generator of composition graphs, the library of primitives and the visualisation module.
