in this work an improved method for designing a linear vibrational absorber, excited by random vibrations is presented and analyzed. first, analytical expressions, for non-stationary white noise accelerations, are derived. the criterion is different from the conventional criteria, used for structural design under random vibration, and it is based on minimum displacement or acceleration response...

Aspectual predesign is an approach to user-verified mapping of the nonfunctional requirements to the system into the aspect-oriented design model. It is an extension of the Klagenfurt Conceptual Predesign. In this paper, we present the architecture of modular software tool aiming to support the aspectual predesign workflow. The XML-based Predesign Exchange Format (PEF) for conversionindependent...

Concerning data and object modeling, conceptual predesign proved useful in overcoming the impedance mismatch between conventional requirements analysis based on natural language and conceptual design. Within this contribution we will present first results on how the conceptual predesign model KCPM (Klagenfurt conceptual predesign model) may be used for the collection and mapping of dynamic requ...

This article describes an improved design procedure for shaped-beam reflectarrays, which is advanced mainly in accuracy and concision. Specifically, the excitation has been computed by a new approach named local simulation instead of mathematical modeling, which demonstrates more advantage in precision. The intersection approach has been applied to optimization, and it is improved by introducin...

We present an approach to capturing the semantics of quality requirements in an intermediate predesign step residing between quality requirements elicitation and conceptual design. We propose Quality-Aware Predesign Model (QAPM) to be used at this step. In this model, the problem domain is viewed as a set of concerns. Out of this set, concerns related to quality are separated from those related...

The paper argues that the conventional methods for object oriented analysis and conceptual modeling suffer from lacks in requirements elicitation and validation by the end-user. Therefore, an intermediate level called ‘conceptual predesign’ is introduced between natural language requirements specification and conceptual design. The paper introduces the basic notions of a conceptual predesign mo...

This paper presents an extension of the Klagenfurt Conceptual Predesign Model (KCPM) allowing taking into account the non-functional requirements to the system. These requirements are treated as crosscutting concerns. This process could be also seen as an addition to the AOSD paradigm that brings the gap between the Aspect-Oriented Requirement Engineering and Aspect-Oriented Modeling. The exten...

This article presents an optimization process applied to the sizing of high-power silicon carbide inverters. The case study is design aeronautical converter. A gradient-based method chosen for its ability explore a wide solution space with large amount constraints, which during predesign phase. Many topologies are selected and associated models developed. Among all these models, active passive ...
