The limited volume of mobile handset and the phenomenon of chassis excitation complicate the design of multiple antennas for MIMO applications. In this work, a compact co-located dual-antenna system implemented on one edge of a 100 mm by 40 mm chassis is proposed for operation below 1 GHz. The dual-antenna structure includes a folded monopole to excite the fundamental electric dipole mode of the c
The dissertation deals with so-called building offerings from the Middle Ages.
Traditional control design using MATLAB/Simulink, often disregards the temporal effects arising fromthe actual implementation of the controllers. Nowadays, controllersare often implemented as tasks in a real-time kernel and communicatewith other nodes over a network. Consequently, the constraints of thetarget system, e.g., limited CPU speed and network bandwidth, must betaken into account at desig
This article deals with the impact of certain retail strategies on urban life. More specifically it deals with two recent tendencies of the retail environment: (a) spatial homogenisation and clustering of retail into large areas or territories, and (b) the synchronisations of retail with different kinds of public activities and events. For the last decades, retail areas have tended to grow larger
In this paper, state estimation for Switched Discrete-Time Linear Systems is performed using relaxed dynamic programming. Taking the Bayesian point of view, the estimation problem is transformed into an infinite dimension al optimization problem. The optimization problem is then solved using relaxed dynamic programming. The estimate of both the mode and the continuous state can then be computed fr
