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
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
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

Statens utlåningsränta till nyföretagare borde vara lägre än hos en traditionell bank. Räntan bör sättas med hänsyn tagen till den samhällsnytta som en finansiering innebär, skriver professor Lars Oxelheim och doktorand Pontus Engström.
