This paper employs Data Envelopment Analysis to measure for the first time the performance of Greek domestic equity mutual funds over four different one-year horizons and for the whole four-year period. In particular, the model used examines whether fund managers employ inputs (i.e. assets, loads, and risk) efficiently to produce output (returns). The results demonstrate that the efficient fund...

The evaluation was performed as follows. For each scenario, 10 bootstrap samplings of the entire data were used to create 10 different train/test splits. No stratification was used. The training part was left unmodified. For the test part, algorithm performances were set to 0 and runstatus to “ok” for all algorithms and all instances – the ASlib specification requires algorithm performance data...

The classical tests of homogeneity, such as the twosample Kolmogorov-Smirnov test, do not have a natural extension to comparing two multivariate populations. G. J. Székely and N. K. Bakirov have proposed a new test based on Euclidean distance between sample elements. This test can be applied to testing homogeneity of any two multivariate populations with finite second moments, and the test is r...

The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

In this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. Two objective functions, real power loss and energy not supplied index (ENS), were utilized. Multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

I and Q Channel phase and gain misniatches are of great concern in communications receiver design. In this paper we analyse the effects of I and Q channel mismatches and propose a lowcomplexity blind adaptive algorithm to minimize this problem. The proposed solution consists of two, 2-tap adaptive filters. arranged in Adaptive Noise Canceller (ANC) set-up, with the output of one cross-fed to th...

This brief review article is appearing in the issue of Statistical Science that marks the 25th anniversary of the bootstrap. It concerns some of the theoretical and methodological aspects of the bootstrap and how they might influence future work in statistics.

A real time, distance lab module is being developed and implemented in the Department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at Urbana-Champaign. This internet based system allows remote personnel to watch the experiments, acquire data, and interact with on-site personnel. The e-lab broadcasts not only the live scenes of laboratory and experiments, but als...
