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)
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)
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)
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)
—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 Shiga toxin-producing Escherichia coli (STEC) O157:H7 is the causal agent for more than 96,000 cases of diarrheal illness and 3,200 infection-attributable hospitalizations annually in the United States. MATERIALS AND METHODS We defined a confirmed case as a compatible illness in a person with the outbreak strain during 10/07/2011-11/30/2011.(More)
The main objective of this paper is to discuss different approaches, identify challenges, and to select a framework for delivering effective sustainability assessments. Sustainable development is an idealistic concept and its assessment has always been a challenge. Several approaches, methodologies and conceptual frameworks have been developed in various(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)
—In this paper, two basic switching cells, P-cell and N-cell, are presented to investigate the topological nature of power electronics circuits. Both cells consist of a switching device and a diode and are the basic building blocks for almost all power electronics circuits. The mirror relationship of the P-cell and N-cell will be revealed.
