We introduce the double–double composite layup method and highlight its advantages over current industry standard method. Proof that (DD) can significantly reduce required number of plies in laminates therefore weight structures is provided. The 4-ply [± ??± ?] sub-laminates also make design manufacturing processes simpler less prone to error compared conventional (quad) layups. Layup homogeniz...

BACKGROUND Promotion of the HIV epidemic by aflatoxin is postulated but not yet established. Sub-Saharan populations commonly consume food contaminated by mycotoxins, particularly aflatoxins (predominantly found in peanut, maize, rice, and cassava) and fumonisins, which occur primarily in maize. Aflatoxin promotes hepatocellular cancer, and fumonisin may promote esophageal cancer. OBJECTIVES ...

BACKGROUND The genome is under constant assault from a multitude of sources that can lead to the formation of DNA double-stand breaks (DSBs). DSBs are cytotoxic lesions, which if left unrepaired could lead to genomic instability, cancer and even cell death. However, erroneous repair of DSBs can lead to chromosomal rearrangements and loss of heterozygosity, which in turn can also cause cancer an...

It has been observed that the fatigueless estimation is based on facial geometric features. However, the geometric features are very often prone to vary to a great extent if the facial pose changes slightly. And the results may be completely 1800 out of phase as that of the desired one. The said problem may be thought of analysis of driver’s facial expression in wavelet domain using entropy of ...

Speech recognition systems are prone to severe degradation in noisy environments due to mismatch between training and testing conditions. A multi-stream approach for keyword spotting is proposed to improve robustness in mismatched conditions. The assumption is that most real world noises are colored and do not affect the full spectrum equally, meaning certain parts of the spectrum can still pro...

The coordination of a large group of robots to solve a specified task is a difficult problem. Centralized approaches can be computationally intractable, brittle, and unresponsive to change. Distributed approaches are not as prone to these problems, but they can be highly sub-optimal. This work introduces a novel approach for coordinating robots based on the free market system. Market economies ...
