The MUTD shall provide electrical power and fiber optic data cable connections between two simulated mars vehicles, about 1000 m apart. The wheeled mobile robot Omnibot is used to provide the mobile base for the system. The mate-to umbilical plate is mounted on a Cartesian robot, which is installed on the Omnibot mobile base. It is desirable to provide the operator controlling the Omnibot, the distance and direction to the target. An approach for finding the position and orientation of the mobile robot for navigation using inertial sensors and beacons is investigated.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

This bus control scheme facilitates utilization of switches with lower voltage ratings in the bridge converter. The control scheme has been explained with analysis. Based on this analysis design example of a 20 kHz, 500 W, 200 V AC-to-DC single-stage bridge converter is presented with explanations on the design constraints. Theoretical results are also predicted based on the analysis. Detailed results obtained from PSPICE simulation are given to verify the advantages claimed for this controlled bus single-stage converter. As a bonus to the bus voltage control, the bottom right switch undergoes zero-voltage switching at reasonably wide load range because of the overlap of the gating signals of two bottom switches in the bridge.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

This work uses pre-configuration for a detailed examination of the network and proposes a tree as the logical topology. The algorithm produces a spanning tree from a WDM mesh network that allows for good restorability while assuring a structure with short routing paths. The shortest path method with cost on the links inversely proportional to the spare capacity is used to find maximum capacity paths between the nodes. Preliminary results show that varying the definition of the cost on the links for the shortest path analysis achieves different tradeoffs in network restorability vs. average path length. In some cases the restorability approaches optimum (for a tree structure), while using minimum spare capacity.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

Several techniques are available to simulate the indoor propagation channel, such as statistical methods or ray tracing methods, they are inspired from their application to characterize mobile radio channels. Nowadays, with the advent of supercomputers, various numerical methods emerged as powerful tools for studying practical indoor propagation problems. This paper reports on a deterministic model developed on the basis of the finite-difference time-domain (FDTD) technique, using the equivalence principle to simulate the base station antenna radiation pattern. The proposed method is validated in a complex room for an indoor radio channel operating at the UHF band, and provides interesting prediction results.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

The exact state space model of the active filter is elaborated in the synchronous 'dq' frame. The model obtained is a nonlinear multi-input multi-output (MIMO) system. It involves two inputs and three outputs which are the state variables of the system. These variables are namely two AC inductor current signals and one DC capacitor voltage signal. The nonlinear multivariable system is highly interconnected; therefore the control of every state variable separately is a difficult task. Based on the nonlinear MIMO model, an input-state feedback linearizing control is derived using an additional third auxiliary input. Hence, the resulting linear model is a decoupled linear system equations. Therefore, a pole placement control strategy is then designed.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat.

For real time applications dedicated to the detection of multi-scale contours, we have developed an algorithm based on the formalism of Mallat (1992) and by using the Deriche (1987) filter generalised as a pure wavelet function and we have established it on FPGA circuits.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

In addition, it is imperative to test the hearing aids with speech signals to accurately predict their \"real world\" performance. In this paper, an adaptive system identification approach is taken to quantify the distortion and noise in a hearing aid. The hearing aid was modelled as a time varying autoregressive moving average (ARMA) system whose coefficients are estimated on a block-by-block basis using the multiple model least squares (MMLS) algorithm. Several speech-based distortion measures are derived from the modelling procedure which is shown to perform well in predicting perceptual judgements of hearing aid quality.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

Adaptive-reduced state sequence detection (A-RSSD) modifies a Viterbi decoder to use far less computational effort than is typical. RSSD neglects the oldest p bits of the encoder's state machine, treating the code as if it were of length K/spl acute/=K-p. Through successive reduction of p, decoding can proceed with more effort until a frame is correctly decoded. This paper describes the only known VLSI implementation of A-RSSD. The presented architecture is an adaptive strength, state-parallel, bit-serial structure. It features soft-decision, continuous stream traceback decoding, with K' ranging from 3 to 11. As such it employs between 4 and 1024 ACS units. The branch metric computer and ACS units are mostly conventional, while special consideration must be given to branch label generation, sub-state estimation, and ACS interconnection structure. Other low-power techniques are also applied, specifically with respect to clock gating, and traceback RAM structure. Design tradeoffs are discussed, and performance estimates are presented.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.
