We focus on the problem of obtaining top-k lists of items from larger itemsets, using human workers for doing comparisons among items. An example application is short-listing a large set of college applications using advanced students as workers. We describe novel efficient techniques and explore their tolerance to adversarial behavior and the tradeoffs among different measures of performance (...
We discuss the interpolation of the electric and magnetic fields within a charge-conserving Particle-In-Cell scheme. The choice of the interpolation procedure for the fields acting on a particle can be constrained by analyzing conservation of the energy and the particle generalized momentum. The better conservative properties are achieved, if the alternating-order form-factor is used for interp...
In this paper, we present a new data mining algorithm which involves incremental mining for user moving patterns in a mobile computing environment and exploit the mining results to develop data allocation schemes so as to improve the overall performance of a mobile system. First, we propose an algorithm to capture the frequent user moving patterns from a set of log data in a mobile environment....
The aim of this paper is to explore the relationship between wages, human capital and investment in financial assets with risky returns at the individual level. To explore this relationship from an international perspective, we analyse individual level data from the British Household Panel Survey, the German Socio-Economic Panel and the U.S. Panel Study of Income Dynamics. Our findings suggest ...
This paper reports a set of experiments motivated by the observation that the design of group decision processes is crucial to the success of electronic meeting room usage. Decision processes can be designed with more emphasis either on exchanging meanings (discussing issues) or exchanging artefacts (generating and structuring topics). Our problem is that, given a particular case to be discusse...
Aircraft cockpit lighting can interfere with the proper operation of night vision goggles (NVGs). Methods to verify compatibility between cockpit lighting and NVGs involve expensive equipment. An inexpensive alternative method to assess compatibility, that provides the same quality of results, is needed. Since the quality of the existing lighting compatibility methods has not been studied, it w...
Wireless Sensor Networks (WSN) is made by an oversized variety of networked sensing nodes. It's rather advanced, or perhaps unworkable, to model analytically a WSN and it always results in simple analysis with restricted confidence. Besides, deploying test-beds supposes a large effort. Therefore, simulation is important to check WSN. However, it needs acceptable model supported solid assum...
In order to make full use of geographic routing techniques developed for large scale networks, nodes must be localized. However, localization and virtual localization techniques in sensor networks are dependent either on expensive and sometimes unavailable hardware (e.g. GPS) or on sophisticated localization calculus (e.g. triangulation) which are both error-prone and with a costly overhead. In...
The recent progress on unquenched QCD simulations is critically reviewed. After some discussions on problems and subtleties in unquenched simulations, hadron spectra obtained from both quenched and unquenched simulations are compared among various gauge and quark actions. It is found that the Edinburgh plot does not agree in the continuum limit between Wilson and KS quark actions even in quench...
