The maximum segment density problem is this: Given a sequence of pairs (ai, wi), i = 1, 2, . . . , n, with wi > 0, and another pair of numbers L ≤ U , we have to find a subsequence ai, ai+1, . . . , aj whose density (ai + ai+1 + . . .+ aj)/(wi +wi+1 + . . .+wj) is maximum under the constraint that L ≤ wi + wi+1 + . . . + wj ≤ U . A principal motivation for studying this problem is its applicati...

This paper studies the use of wireless Ethernet (Wi-Fi) as a localization sensor for mobile robots. Wi-Fi-based localization relies on the existence of one or more Wi-Fi devices in the environment to act as beacons, and uses signal strength information from those beacons to localize the robot. Through the experiments described in this paper, we explore the general properties of Wi-Fi in indoor ...

BACKGROUND AND PURPOSE Withanolides are naturally occurring chemical compounds. They are secondary metabolites produced via oxidation of steroids and structurally consist of a steroid-backbone bound to a lactone or its derivatives. They are known to protect plants against herbivores and have medicinal value including anti-inflammation, anti-cancer, adaptogenic and anti-oxidant effects. Withafer...

Background: Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...
