In this paper, a new formulation for acoustics coupled with linear elasticity is presented. The primary objective of the work is to develop a three dimensional hp adaptive finite element method code destinated for modeling of acoustics of human head. The code will have numerous applications e.g. in designing hearing protection devices for individuals working in high noise environments. The pres...

Our approach is inherently multi-disciplinary, blending the key disciplines of geology/geophysics (G&G) and acoustics, linked by the field of geoacoustics. For many years, the underwater acoustics community has probed sediment geoacoustics through inverse modeling of acoustic measurements (e.g., propagation, reverberation) or via empirical relations (e.g., Hamilton, 1980) or physics-based model...

The study of structural acoustics involves modeling acoustic radiation and scattering, primarily in exterior regions, coupled with elastic and structural wave propagation. This paper reviews recent progress in nite element analysis that renders computation a practical tool for solving problems of structural acoustics. The cost-eeectiveness of nite element methods is composed of several ingredie...

In the development of groupware systems a well designed communications infrastructure is required, due to the high complexity of the communication scenario. Also, the design and implementation of coordination and collaboration mechanisms depends on the communications infrastructure. Actually there are no well known guidelines to design this infrastructure. Therefore, this paper proposes an arch...

TRADITIONALLY, SOFTWARE architects were entrusted with making “decisions that are costly to change.”1 Because these decisions often had to be made early in the project, architects drew on their experience and ability to abstract to get them right. Repeated project cost and timeline overruns have demonstrated, though, that trying to plan all features and decide the system structure early in a pr...

In this paper we introduce a content-oriented scheme for protocol studies of designers and demonstrate its benefit for CAAD research. The structure of the coding scheme is described. We discuss how this method can benefit CAAD research and its differences from the process-oriented method used previously. With this method we analyze data to describe the design process as the combination of senso...

This paper presents the Acoustics Apps, an e-learning platform that offers interactive and playful environment for teaching learning principles of acoustics vibration. The Apps address increasing demand digitized methods, which might be suitable home schooling or as a complement to physical experiments by adding simulation. apps combine experimenting, observing, exploring using state-of-the-art...

With a general decline in people's choosing to pursue science and engineering degrees there has never been a greater need to raise the awareness of lesser known fields such as acoustics. Given this context, a large-scale public engagement project, the 'Aeolus project', was created to raise awareness of acoustics science through a major collaboration between an acclaimed artist and acoustics res...

banjarmasin is known as a tidal waterfront city and it is called city of a thousand rivers. thecity level was approximately -16 cm below the sea level and almost a swamp-land. the urbanization and the citydevelopment programs have changed the city’s physical and spatial plan from a wetland to a mainland structure. theissues of the city's transformation have changed the city structure from ...
