The possibility that the developmental effects of genes are influenced by their neighbors in the chromosomes has only recently become accessible to experiment. The first demonstration of such an effect was given by STURTEVANT (1925). Two Bar genes in Drosophila melanogaster, placed in the same chromosome as a result of unequal crossing over, are more effective than two similar genes present in ...

This study was conducted to identify the technical and economical performance of the existing models of maize sheller in the country and suggest the best maize sheller models for the farmers during 3 September 2006 to 30 March 2007 in the area of Bogra, Rangpur, Dinajpur, Rajshahi and Jessore. Detail field tests were conducted on seven selected maize sheller models of three categories to assess...

The increased frequency of sudden cardiac death after earthquakes and bombings has long proposed that emotional distress plays a role in acute coronary syndromes and arrhythmias. Since the 1960s, several controlled, prospective, epidemiological studies have reported emotional distress as a major risk factor for the onset and worsening of coronary heart disease (CHD) [1]. The Interheart study, a...

This paper proposes the use of the Teager–Kaiser energy operator (TKEO) for the detection of a broken rotor bar (BRB) in a squirrel cage induction generator, which is used usually in wind energy systems. The TKEO is investigated using the non-stationary signals representation in the time/frequency domain by sensing the estimation of the instantaneous amplitudes and frequencies present on the st...

Broken adaptive ridge (BAR) is a computationally scalable surrogate to $$L_0$$ -penalized regression, which involves iteratively performing reweighted $$L_2$$ penalized regressions and enjoys some appealing properties of both while avoiding their limitations. In this paper, we extend the BAR method semi-parametric accelerated failure time (AFT) model for right-censored survival data. Specifical...

In this paper, a novel method for broken bars fault detection in the case of three-phase induction motors and under different payloads will be presented and experimentally evaluated. In the presented approach, the cases of a partially or full broken rotor bars are being also considered, caused by: (a) drilling 4 mm and 8 mm out of the 17 mm thickness of the same rotor bar and (b) fully drilled ...
