Optimal Linear Joint Source-Channel Coding with Delay Constraint

The problem of joint source-channel coding is considered for a stationary remote (noisy) Gaussian source and a Gaussian channel. The encoder and decoder are assumed to be causal and their combined operations are subject to a delay constraint. It is shown that, under the mean-square error distortion metric, an optimal encoder-decoder pair from the linear and time-invariant (LTI) class can be found

An extremum seeking approach to parameterised loop-shaping control design

An approach to loop-shaping feedback control design in the frequency domain via extremum seeking is proposed. Both plants and controllers are linear time-invariant systems of possibly infinite dimension. The controller is assumed to be dependent on a finite number of parameters. Discrete-time global extremum seeking algorithms are employed to minimise the difference between the desired loop shape

Vattenomsättning i några svenska städer

Den inre och yttre vattenomsättningen i sex svenska städer har studerats.Dagvatten från hårda ytor till kombinerade system har beräknats liksomdränering av mark och grundvatten till detta system. Diffus avrinningutanför spill- och dagvattensystem har också beräknats. Inläckage tillspillvattensystem är ganska lika i de sex städerna. Det diffusa flödet tillrecipienter beror på klimatfaktorer.The inner and outer water balance in six Swedish cities has been studied.Direct stormwater contribution to the combined system has beendetermined, as has drainage of soil and groundwater to this system.Diffuse runoff not being in the sewerage or stormwater systems has alsobeen determined. The leakage into the sewerage system is almost thesame in all cities. The diffuse runoff depends on climatic f
