In our work we focus on Robotic Mobile Fulfillment Systems in e-commerce distribution centers. These systems were designed to increase pick rates by employing mobile robots bringing movable storage units (so-called pods) to pick and replenishment stations as needed, and back to the storage area afterwards. One advantage of this approach is that repositioning of inventory can be done continuousl...

We explore the design space of Field Programmable Gate Arrays (FPGAs), Processors and ASICs – Hardware-Software Tri-design – in the framework of encryption for hand-held communication units. IDEA (International Data Encryption Algorithm) is used to show the tradeoffs for the suggested technologies. The measures for comparing different options are: Performance, Programmability and Power (P ). Mo...

Professor M Arnaud Doctors worldwide are becoming increasingly aware of the need for transporting some patients under medical supervision and optimum conditions by using mobile medical or paramedical units.

In this paper we consider databases representing information about moving objects (e.g. vehicles), particularly their location. We address the problems of updating and querying such databases. Specifically, the update problem is to determine when the location of a moving object in the database (namely its database location) should be updated. We answer this question by proposing an information ...
