The dynamic and lossy nature of wireless communication poses major challenges to reliable, self-organizing multihop networks. These non-ideal characteristics are more problematic with the primitive, low-power radio transceivers found in sensor networks, and raise new issues that routing protocols

This paper describes non-ideal properties of batteries and how these properties may impact power-performance trade-offs in wearable computing. The first part of the paper details the characteristics of an ideal battery and how these characteristics are used in sizing batteries and estimating

Abstract – This paper extends the design of steerable broadband beamformers by incorporating robustness in the design formulation to cater for microphone mismatches and other non-ideal characteristics. In our method, a 2-norm constraint on the filter weights is imposed in the design optimisation

. The model shows that Carnot efficiency is achieved from the ideal work-generating cycle for a regenerator with unity effectiveness. However, for non-ideal conditions, thermal efficiency is highly sensitive to the regenerator performance. For example, assuming zero dead volume in the system, for a

The development of quantum protocols from conception to experimental realizations is one of the main sources of the stimulating exchange between fundamental and experimental research characteristic to quantum information processing. In this thesis we contribute to the development of two recent

This paper proposes a framework for separating several speech sources in non-ideal, reverberant environments. A movable human dummy head residing in a normal office room is used to model the conditions humans experience when listening to complex auditory scenes. Before the source separation takes

It is well known that non-ideal magnetohydrodynamic effects are important in the dynamics of molecular clouds: both ambipolar diffusion and possibly the Hall effect have been identified as significant. We present the results of a suite of simulations with a resolution of 512 3 of turbulent decay

are recognized as valuable model system for the study of phase transitions and other collective processes including transport properties. In this paper the results of investigation of transport processes such as diffusion of dust particles and formation of dust vortices in the strongly non-ideal dusty plasma

and downlink receivers. Third generation receivers are mainly based on coherent detection. Carrier frequency, carrier phase, multipath profile, path delays as well as fading characteristics are important parameters to perform a coherent detection of transmitted symbols. Several multi-user receivers for Direct

Data from these environments are presented in the following section. 7.1.1 Free Space Calibration The ideal free space environment, measured with an ideal system, produces an all-ones H-matrix and results in the minimum theoretical MEA capacity. Non-ideal characteristics of the measurement
