Since 3D graphics applications (like entertainment, information visualization or training applications) are getting more and more complex it is necessary to improve the production process. Software engineering concepts, which were developed to build large software systems in a fast and reliable manner, offer promising solutions. In this contribution we will present an adaptation of framework an...

The efficient operation of building systems is important energy efficiency, comfort and safety. Determining when maintenance is required or when a fault has occurred is the focus of this work. We show how to use available performance data in a methodology for improved maintenance scheduling through anomaly detection. We apply two statistical prognostic techniques – Particle Filters and Gaussian...

Designing high-performance algorithms for computationally hard problems is a difficult and often time-consuming task. In this work, we demonstrate that this task can be automated in the context of stochastic local search (SLS) solvers for the propositional satisfiability problem (SAT). We first introduce a generalised, highly parameterised solver framework, dubbed SATenstein, that includes comp...

We present an active triangulation range finding system composed of an independant laser system generating a plane of light projected on an object placed upon a rotary table driven by a personal computer. This computer includes a video digitizer board connected to a camera looking at the scene. Besides its low cost, this system has other advantages over the comparable existing systems. First, w...

In recent years, the hardware description languages, and the standard VHDL in particular, are intensively used to describe different aspects of hardware designs. The rapid development of CAD tools on the language basis have sped up and improved the design process considerably. The design methods, however, have not kept the pace with the needs and requirements for design productivity and quality...

The AECOO industry is highly fragmented; therefore, efficient information sharing and exchange between various players are evidently needed. Furthermore, the information about facility components should be managed throughout the lifecycle and be easily accessible for all players in the AECOO industry. BIM is emerging as a method of creating, sharing, exchanging and managing the information thro...

Meta modeling is an effective approach to implement interoperability among many distributed and heterogeneous information sources. A MMF (Meta Model Framework) is a set of Meta objects and Meta modeling constructs to be used in the development a metamodel in the actual implementation of a registry. This paper proposes a common repository model based on MMF to ensure interoperability among heter...

Design of assemblies will become an area of study when using rapid prototyping devices in the architectural design process becomes standard practice. This paper is a presentation of a design process study focused on understanding a method of working with rapid prototyping devices in a creative design process. This paper has an emphasis is on the creation of physically large models. These models...
