Biometric authentication techniques are more consistent and efficient than conventional authentication techniques and can be used in monitoring, transaction authentication, information retrieval, access control, forensics, etc. In this paper, we have presented a detailed comparative analysis between Principle Component Analysis (PCA) and Independent Component Analysis (ICA) which are used for f...

The turbulence refractivity structure constant (Cn) is an important parameter of the atmosphere. VHF radars have been used extensively for the measurements of Cn. Presently, most of such observations are from mid and high latitudes and only very limited observations are available for equatorial and tropical latitudes. Indian MST radar is an excellent tool for making high-resolution measurements...

The purpose of this study was to measure and describe postural aberrations in chronic and acute low back pain in search of predictors of low back pain. The sample included 59 subjects recruited to the following three groups: chronic, acute, or no low back pain. Diagnoses included disc disease, mechanical back pain, and osteoarthritis. Lumbar lordosis, thoracic kyphosis, head position, shoulder ...

This study investigated the effects of initial load height and foot placement instruction in four lifting techniques: free, stoop (bending the back), squat (bending the knees) and a modified squat technique (bending the knees and rotating them outward). A 2D dynamic linked segment model was combined with an EMG assisted trunk muscle model to quantify kinematics and low back loading in 10 subjec...

With the rapid development of computer network and information technology, traditional clothing industry has taken a giant stride forward to computer information and digitization. In this paper, 250 3D point-cloud photos of young females were selected as subjects, and related characteristic points of neck rhizosphere (including front neck point, side neck point and back neck point) were determi...

It’s a problem not widely faced amongst animals: but, for those such as beetles and turtles with hard, round shells, it is serious. Ending upside down presents a major, lifethreatening problem if they are unable to right themselves pretty quickly. A new study of this convex problem is reported by Gabor Domokos at the Budapest University of Technology and Economics and Peter Varkonyi at Princeto...

The purpose of this study was to compare the traditional height-adjustable shower trolley with the Carevo, a shower trolley with a new design. Compared to the traditional height-adjustable shower trolley, the Carevo has higher side supports, indented curves on the long sides, handles, arrow-shaped ends, and a mattress with a flexible mid-section. In this study four nurses carried out five showe...

Sound patterns of vowel harmony reduce articulatory effort which facilitates speech production with increased speech rate and accuracy. We argue that back harmony patterns reduce articulatory effort compared to height harmony and non-harmony patterns and harmony patterns formed from front unrounded (FU) vowels reduce articulatory effort compared to those of front rounded (FR)vowels. We report o...
