An 18th (4th+14th) order gm -C IF filter for the Bluetooth short-range radio, implemented in a 0.6 μm CMOS process, is presented. The filter bandwidth is 1 MHz, the center frequency fc is 3 MHz, the in-band group delay variation is 0.75 μs, and the stop-band attenuation at fc±1 MHz is at least 47 dB. The noise floor is 250 μVr.m.s. and the spurious free dynamic range is at least 58 dB for out-of-b

This document describes the methodology for the evaluation and the assessment of the Safe Speed – Safe Distance (SSSD) concept of the SASPENCE system. It describes the evaluation using the prototype vehicles from a technical and functional point of view, as well as to assess such a system by a subjective rating by the driver. In particular, the first part is the report on the pilot plan design, th

The project “Arson - a societal problem” has been running with funding from a number of players since 2008. The project consists of a number of sub-projects and the work presented in this report was conducted within the sub-project: "Technical- and risk-based methods to prevent and mitigate the consequences of arson". The goal and purpose of the project was to develop and evaluate technical system

This paper presents a method for optimal control of hybrid systems. An inequality of Bellman type is considered and every solution to this inequality gives a lower bound on the optimal value function. A discretization of this ``hybrid Bellman inequality'' leads to a convex optimization problem in terms of finite-dimensional linear programming. From the solution of the discretized problem, a value

Virtual reality carries great promise to facilitate the building process. Some examples are the communication between architects and building companies, sellers and buyers or the community planners and the general public. It is often thought that in order to utilize the possibilities of VR, for example in the above-mentioned contexts, it is necessary to use full-fledged versions of VR including fo

This paper describes the development of a modular system of interactive tiles to support therapists’ in performing therapeutic activities together with impaired children in a swimming pool. Active Surfaces support mobile interactions and dynamic configuration of assemblies of tiles. Each tile represents an interactive unit, able to communicate with other tiles and to exchange data. The tiles can

Just like other newly introduced concepts such as 'science', 'culture', or 'religion', the widely used Chinese term for 'profession' – zhiye – has been established with its modern meaning only in the course of this century, especially after the foundation of the 'Chinese Society of Vocational Education' by Huang Yanpei in 1917. However, the term itself is not a new one, but is the product of ancie
