An Analytical Model Based on G/M/1 with Self-Similar Input to Provide End-to-End QoS in 3G Networks

The dramatic increase in demand for wireless Internet access has lead to the introduction of new wireless architectures and systems including 3G, Wi-Fi and WiMAX. 3G systems such as UMTS and CDMA2000 are leaning towards an all-IP architecture for transporting IP multimedia services, mainly due to its scalability and promising capability of inter-working heterogeneous wireless access networks.

Soundcrumbs – Hansel and Gretel in the 21st century

This paper presents a novel application which implements a way of adding sound breadcrumbs to the environment. We report results from initial user tests which suggest that this type of design could be useful for a wide range of mobile location based applications.

Automotive Radar Transmitter at 24-GHz with Digital Beam Steering in 130-nm CMOS

In this paper simulations of a 130-nm CMOS 24-GHz automotive radar transmitter with digital beam steering is presented. The beam steering is performed by multiple PAs connected to separate antenna elements. The output phases of the PAs are individually controllable through 360◦ by binary weighting of quadrature phases. The circuit contains 18 PAs, each delivering 0 dBm to the antenna, resulting in

Laser-induced Phosphorescence for Surface Thermometry in the Afterburner of an Aircraft Engine

In the present work, surface thermometry using a method based on the spectroscopy of inorganic luminescent material was applied in the afterburner of a full-size aircraft jet engine. The technique uses laser-induced emission from thermographic phosphors for nonintrusive remote temperature diagnostics in combustion applications with high sensitivity and accuracy. A phosphor material having suitable

Traceability in fish supply chain - Evaulating two suppply chain mapping techniques

Purpose of this paper The paper describes and examines the information flow in three fish supply chains, when the package is treated as an information carrier. Included is an evaluation of two supply chain mapping techniques for examining the interfaces for the achievement of better traceability and by this supply chain and logistic efficiency. Design/methodology/approach The research is based on
