Robust performance is said to be achieved if the performance specifications are met for all plants in a specified set. Classical loopshaping was developed decades ago to design for robust performance for single-loop systems with simple uncertainty and performance specifications. Specifications are often not so simple-multiple real parameter variations are not handled by classical loopshaping, f...

Process control charts are proven techniques for improving quality. Specifying the control limits is the most important step in designing a control chart. The presence of outliers may extremely affect the estimates of parameters using classical methods. Robust estimators which are not affected by outliers or the small departures from the model assumptions are applied in this paper to specify th...

One of the fundamental problems in the classic DEA is lack of ability to distinguish unit's performance scores that is considered as a disadvantage. Recently, Parkan et al. [9] tried to address this problem.   They proposed to assess each unit both optimistic and pessimistic views are taken into account. In contrast to traditional evaluation, one index is considered for each unit based on the l...

In disaster management scenarios with seriously damaged, not existing, or saturated communication infrastructures satellite communications can be an ideal means to provide connectivity with unaffected remote terrestrial trunked radio (TETRA) core networks. However, the propagation delay imposed by the satellite link affects the signalling protocols. This paper discusses the suitability of using...

In this paper a discrete-time sliding mode approach for the control of nonholonomic robots performing a leader following task is presented. The task can be seen as a service task for bringing robots to a working area. Our aim is to design, develop and test a new software and hardware framework for formation and coalition problems in a mobile multi robot scenario. Given a desired robot coalition...
