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.

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

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
This paper is concerned with the a priori theory of the photoemission process in solids. Scattering-theoretical and response-theoretical approaches are discussed and a new demonstration of their equivalence is given. The elastic photoemission spectrum is analyzed in detail and an expression exact to all orders in interparticle interaction is obtained. This expression is similar to the renormalized
