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

B2B rather than B2C to Meet Customer Demands in the Pharmaceutical Retail Industry

An increased use of the Internet has created new business opportunities. The development of e-commerce has, however, been crippled by a limited understanding of logistics and customer needs. This paper sets out to highlight those issues in pharmaceutical retail where added services should be created through e-commerce. The research is based upon a case study covering the pharmaceutical system in S

Artificial recharge by floodwater spreading estimated by water balances and groundwater modeling

Water harvesting and artificial recharge have been the main and parsimonious solution for water scarcity problems in the arid and semiarid Middle East for thousands of years. These techniques are increasingly being encouraged and at present there has been a renewed interest to find improved methods for water harvesting and artificial recharge in many arid countries. In the present study water bala
