In this paper we consider the following robust twoblock problem that arises in est,imation and in fullinformation control: minimize the worst-case H” norm of a two-block transfer matrix whose elements contain H”-norm-bounded modeling errors. We show that, when the underlying systems are single-input/singleoutput, and if the modeling errors are “small enough”, then t,he robust, two-block problem...

In contrast to the increasing popularity of REpresentational State Transfer (REST), systematic testing of RESTful Application Programming Interfaces (API) has not attracted much attention so far. This paper describes different aspects of automated testing of RESTful APIs. Later, we focus on functional and security tests, for which we apply a technique called model-based software development. Ba...

A grand challenge for power grid management lies in how to plan and operate with increasing penetration of distributed energy resources (DERs), such as solar photovoltaics and electric vehicles, which disturb the power grid stability. Existing approaches are unable to verify if a point is on a loadability boundary or characterize all loadability boundary points exactly. This inability leads to ...

The ability to stream data between web-services is vital for the implementation of complex workflows on the Grid. In this work we investigate various protocols as to their suitability for streaming, taking into consideration issues such as security, reliability and speed over different Grid configurations. To perform these comparisons we have implemented a Server/Client web service that provide...

Miners in underground coal mines experience prolonged exposure to high noise levels, often with A-weighted sound levels in excess of 90 dB. Field tests have shown that the continuous miner conveyor is a dominant noise source. This paper will identify the most significant noise-radiating surfaces on the continuous miner tail section using vibration levels and surface areas to estimate the sound ...

The one-loop scattering amplitude for sixgluons in pure QCD has been an interesting test case for the development of analytic techniques in perturbative gauge theories. The amplitude can be decomposed into various subamplitudes which were calculated between 1993 and 2006 [1–13] in thirteen different publications by 23 authors. The results for the amplitude are spread across a large number of pa...

in this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (epl) and flexor pollicis longus (fpl) tendon avulsion from the tenomuscular junction. after metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. transfer of e...
