The 3rd generation partnership project (3GPP) long term evolution (LTE) standard uses single carrier frequency division multiple access (SCFDMA) scheme for the uplink transmissions and orthogonal frequency division multiplexing access (OFDMA) in downlink. SCFDMA uses DFT spreading prior to OFDMA modulation to map the signal from each user to a subset of the(More)
We investigated the effects of two commercial diatomaceous earth based insecticides (DE), Protect-It® and SilicoSec®, the nano-structured silica product AL06, developed by the section for Urban Plant Ecophysiology at Humboldt University Berlin, and the monoterpenoids, eugenol, and cinnamaldehyde on two stored product pests, Callosobruchus maculatus and(More)
In developing countries threat of cholera is a significant health concern whenever water purification and sewage disposal systems are inadequate. Vibrio cholerae is one of the responsible bacteria involved in cholera disease. The complete genome sequence of V. cholerae deciphers the presence of various genes and hypothetical proteins whose function are not(More)
Speech recognition and speaker identification are important for authentication and verification in security purpose, but they are difficult to achieve. Speaker identification methods can be divided into textindependent and text-dependent. This paper presents a technique of text-dependent speaker identification using MFCC-domain support vector machine (SVM).(More)
BACKGROUND Analyzing the structures and functions of different proteins of Wuchereria bancrofti is very important because till date no effective drug or vaccine has been discovered to treat lymphatic filariasis (LF). ATPase is one of the most important proteins of Wuchereria bancrofti. Adenosine triphosphate (ATP) converts into adenosine diphosphate (ADP)(More)
By means of dynamic mechanical thermal analysis (DMTA), selected tropical wood species, namely Eugenia spp., Artocarpus rigidus, Artocarpus elesticus, Koompassia malaccensis, and Xylopia spp. have been characterized. The woods were treated with sodium meta-periodate to convert them into wood polymer composites (WPC). After two weeks the WPC were chemically(More)
BACKGROUND Bacillus anthracis is a gram positive, spore forming, rod shaped bacteria which is the etiologic agent of anthrax - cutaneous, pulmonary and gastrointestinal. A recent outbreak of anthrax in a tropical region uncovered natural and in vitro resistance against penicillin, ciprofloxacin, quinolone due to over exposure of the pathogen to these(More)
This paper presents a reliable method for detecting human faces in color images. The system is based on the visual information of the face and is commenced with the detection of face regions by connected component analysis of the skin color segmentation of images in HSV,YCBCR,YIQ color model and the Fuzzy membership function. The Fuzzy Membership function(More)
