We study the empirical strategies that humans follow as they teach a target concept with a simple 1D threshold to a robot. 1 Previous studies of computational teaching , particularly the teaching dimension model and the curriculum learning principle , offer contradictory predictions on what optimal strategy the teacher should follow in this teaching task.(More)
We present the case of a 13-year-old boy with a congenital anterior urethral diverticulum. This is a rare condition in males which can lead to obstructive lower urinary tract symptoms and urosepsis. Diagnosis is by urethroscopy and radiological imaging. Surgical treatment can be open or endoscopic. Long-term followup is required to check for reoccurrence of(More)
Large scientific collaborations are moving towards service oriented architectures for implementation and deployment of globally distributed systems. Clarens is a high performance, easy to deploy Web Service framework that supports the construction of such globally distributed systems. This paper discusses some of the core functionality of Clarens that the(More)
Accurate and real-time traffic measurement is becoming increasingly critical for large variety of applications including accounting, bandwidth provisioning and security analysis. Existing network measurement techniques, however, have major difficulty dealing with large number of flows in today's high-speed networks and offer limited scalability with(More)
High Energy Physics (HEP) and other scientific communities have adopted Service Oriented Architectures (SOA) [1][2] as part of a larger Grid computing effort. This effort involves the integration of many legacy applications and programming libraries into a SOA framework. The Grid Analysis Environment (GAE) [3] is such a service oriented architecture based(More)
BACKGROUND Forensic Short Tandem Repeat (STR) loci are effective for the purpose of individual identification, and other forensic applications. Most of these markers have high allelic variability and mutation rate because of which they have limited use in the phylogenetic reconstruction. In the present study, we have carried out a meta-analysis to explore(More)
—Programmable analysis of network traffic is critical for wide range of higher level traffic engineering and anomaly detection applications. Such applications demand stateful and programmable network traffic measurements (NTM) at high throughputs. We exploit the features and requirements of NTM, and develop an application-specific FPGA based Partial Dynamic(More)
Streaming network traffic measurements and analysis is critical for detecting and preventing any real-time anomalies in the network. The high speeds and complexity of today's network make the traditional slow open-loop measurement schemes infeasible. We propose an alternate closed-loop measurement paradigm and demonstrate its practical realization. To the(More)
BACKGROUND The Renin-Angiotensin system (RAS) is a key regulator of both blood pressure and kidney functions and their interaction. In such a situation, genetic variability in the genes of different components of RAS is likely to contribute for its heterogeneous association in the renal disease patients. Angiotensin converting enzyme-1 (ACE-1) is an(More)
— Discovery Systems (DS) can be considered as entry points for global loosely coupled distributed systems. An efficient Discovery System in essence increases the performance, reliability and decision making capability of distributed systems. With the rapid increase in scale of distributed applications, existing solutions for discovery systems are fast(More)
