In this dissertation, I generalize the relocation analysis of MAC algorithms for Mobile Ad-hoc Network by creating different mobility models. The models of Constrainedjump mobility, Parallel-motion and Flock mobility were implemented in TOSSIM. The Constrained-jump model is used for simulating two versions of a MAC Algorithm [3, 9] and comparing their performance. Two functions are derived from...

The interplay of vibrational motion and electronic charge relocation in an ionic hydrogen-bonded crystal is mapped by X-ray powder diffraction with a 100 fs time resolution. Photoexcitation of the prototype material KH(2)PO(4) induces coherent low-frequency motions of the PO(4) tetrahedra in the electronically excited state of the crystal while the average atomic positions remain unchanged. Tim...

Adult-born neurons adjust olfactory bulb (OB) network functioning in response to changing environmental conditions by the formation, retraction and/or stabilization of new synaptic contacts. While some changes in the odour environment are rapid, the synaptogenesis of adult-born neurons occurs over a longer time scale. It remains unknown how the bulbar network functions when rapid and persistent...

Mobile robots with sensors installed on them are used in wireless sensor networks to generate information about the area. These mobile robotic sensors have to relocate themselves after initial location in the field to gain maximum coverage The average distance based algorithm for relocation process of mobile sensors does not require any GPS system for tracking the robotic sensors, thus avoiding...

We reports here the effects of transference senior citizenspatients from pune suburban areas hospitals were evaluated. Relocation senior citizenspatients have reported for the first time from Indian hospitals, especially from developed cities in India. Researcher interest in the clinical consequences of relative deficiency identified in the aging male caring is well served by the series of pape...

BACKGROUND Advancements in upper limb prosthesis design have focused on providing increased degrees of freedom for the end effector through multiple articulations of a prosthetic hand, wrist and elbow. Measuring improvement in patient function with these devices requires development of appropriate assessment tools. OBJECTIVES This study presents a refined clothespin relocation test for measur...

Numerical applications frequently contain nested loops that process large arrays of data. The execution of these loop structures often produces memory reference patterns that utilize data caches poorly. Indeed, poor reuse of the data, large working set sizes, and frequent non-unit stride accesses all combine to cause many cache misses. To improve cache performance, data copying has been propose...

BACKGROUND We assessed mobility in different life stages over a 29-year period from adolescence through adulthood and its correlation with psychosocial stress and vital exhaustion at ages 32 and 42 years. METHODS Data were derived from the Amsterdam Growth and Health Longitudinal Study, an observational longitudinal study of 420 boys and girls from age 13 to 42 years. Measurements included cu...

An oocyte matures into an egg by extruding half of the chromosomes in a small polar body. This extremely asymmetric division enables the oocyte to retain sufficient storage material for the development of the embryo after fertilization. To divide asymmetrically, mammalian oocytes relocate the spindle from their center to the cortex. In all mammalian species analyzed so far, including human, mou...
