This research investigates the design of a radio Direction Finder (DF) for rescue op-eration using victims ’ cellphone as localization beacons. The conception is focused on an audio interface, using sound to progressively guide rescuers towards their target. The thesis ’ ambition is to exploit the natural mechanisms of human hearing to improve the global performance of the search process rather than to develop new Direction-Of-Arrival (DOA) estimation techniques. Classical DOA estimation techniques are introduced along with a range of tools to assess their efficiency. Based on these tools, a case study is proposed regarding the performance that might be expected from a lightweight DF design tailored to portable operation. It is shown that the performance of high-resolution techniques usually implemented for DOA estimation are seriously impacted by any size-constraint applied on the DF, particularly in multi-path propagation conditions. Subsequently, a review of interactive parameter mapping sonification is proposed. Various sonification paradigms are designed and assessed regarding their capacity

The Virtual Test Bed (VTB) is a software environment that supports design, analysis, and virtual prototyping of electric power systems, with an emphasis on naval applications. This paper describes the status of development of the VTB and its use in the multi-technical field of ship power systems.

Currently quite a number of VP definitions are given in litera-Downloaded Fture and in industry. The following includes a few of these defi-nitions. ‘‘Virtual Prototyping ~VP! is a relatively new technology which involves the use of Virtual Reality ~VR! and other computer tech-nologies to create

Virtual prototyping as an embedded system design technique has the potential to significantly increase efficiency of the design process. An environment for automatic generation of virtual prototypes (VPs) directly from algorithmiclevel descriptions is presented here. It is implemented as part of a

ABSTRACT: VP means virtual prototyping is a computer aided design process. It is the latest and cost effective way to visualize real circumstances that enhance effective communication of design and ideas without manufacturing physical samples. Virtual prototyping involves the integration

time. WWT is a virtual prototype that exploits similarities between the system under design (the target) and an existing evaluation platform (the host). The host directly executes all target program instructions and memory references that hit in the target cache. WWT's shared memory uses the CM-5

Virtual prototypes are simulators used in the consumer electronics industry. They enable the development of embedded software before the real, physical hardware is available, hence providing important gains in speed of development and time-to-market. Transaction-level Modeling (TLM) is a widely

This stage of the codesign process starts with a virtual prototype, an heterogeneous architecture composed of a set of distributed modules, represented in VHDL for hardware elements and in C for software elements, communicating through communication modules. This work concentrates on a

The focus of this dissertation is on the design, virtual prototyping and physical re- alization of ote-of-a-kitd assistire devices that are physically coupled or attached to the human user. This class of articulated assistive devices called teletheses are designed to be passive. The intimate

A Modelling Environment for the geometrical, topological and functional specification of mechatronic systems will be presented. The close coupling of real model components and their virtual counterparts allows a synchronous construction of real and virtual prototypes and their evaluation. I
