Global Enterprises today are dependent on performance within complex networks. To become effective and efficient, it is more important than ever to organize operations in order to capitalize on resources and to integrate different activities. This means that the supply chain and logistics have become core activities in international enterprises. Transportation has also become an issue based on the
This paper describes a project course that focuses on the design of analog and mixed signal circuits through a systematic top down design flow. In the project, the student will be involved in the planning, modeling, circuit level design, physical level implementation and measurement verification of for example a successive approximation (SA) ADC or a class-D audio amplifier. Throughout the project
Design science research involves creating and evaluating innovative methods and approaches to be used in design practice. We present an approach to be used in the process of designing Management Support Systems (MSS). The nature of managerial work makes the design, development, and implementation of MSS a major challenge. The MSS literature suggests that determining MSS requirements and specificat
Objective-To evaluate early neuropathy in dental personnel exposed to high frequency vibrations. Methods-30 dentists and 30 dental hygienists who used low and high speed hand pieces and ultrasonic scalers were studied, and 30 dental assistants and 30 medical nurses not exposed to vibration (all women). Vibrotactile sensibility, strength, motor performance, sensorineural symptoms and signs, and vas
The benefits of integrating a real-time oriented language for description of control algorithms, PAL, into a package for computer aided control system design, SIMART, are investigated. An anti-wind-up partial state model reference controller, designed and validated in this environment, has been successfully tested in real-time on a double tank system.
In this paper we introduce an approach to analyze the interaction between antennas and the propagation channel. We study both the antennas and the propagation channel by means of the spherical vector wave mode expansion of the electromagnetic field. Then we use the expansion coefficients to study some properties of general antennas in those fields by means of the antenna scattering matrix. The foc
The EU project ALVIS - Superpeer Semantic Search Engine, aiming at developing an Open Source prototype of a peer-to-peer, semantic based search engine, is brie°y presented. A focused (or topic speci¯c) crawler, responsible for creating topic-speci¯c databases within ALVIS, is presented in more detail. It is based on a combination of a standard Web crawler and an automated subject classi¯er. The to
