The ship speed through water (STW) is a critical variable for evaluation of performance. With cubic relation to the expected shaft power, even small inaccuracies in measured STW amplifies more considerable power. traditionally using log, specifically by Doppler acoustic log principle. stability and precision this technique however questionable, particularly when ships are exposed waves. For equ...

Performance analysis of manufacturing systems : queueing approximations and algorithms / Acknowledgements This thesis is the result of more than four years of work. It actually started in August 2002, when Jan van Doremalen gave me the opportunity to carry out my master's thesis at CQM. My supervisors Simone Resing and Ivo Adan played an important role in my decision to continue the research in...

We present observations of probable line-of-sight acceleration of a broad absorption trough of C IV in the quasar SDSS J024221.87+004912.6. We also discuss how the velocity overlap of two other outflowing systems in the same object constrains the properties of the outflows. The Si IV doublet in each system has one unblended transition and one transition which overlaps with absorption from the o...

The investigation was undertaken on 110 Gir crossbred cows of different order lactation and stage maintained at Research Cum Development Project Cattle, MPKV, Rahuri. overall least squares means udder length, width, depth circumference were 65.23 ± 1.45, 63.24 19.03 0.51 86.49 1.50 cm respectively. analysis variance showed significant (P<0.05) effect due to length in cows. Also, had (P<0...

Introduction: A precursory glance at MGS images of the surface of Mars show an abundance of aeolian transverse ridges [1]. These ridges are located in a variety of geological terrains. Zimbelman and Wi lson [2] have separated the small-scale aeolian features of Syrtis Major into six categories: ripples associated with obstacles, ripple bands, ripple fields, ripple patches, isolated ripple patch...

This paper presents the results of a study of the peculiarities of subsurface longitudinal (head) waves (SLW) and transverse waves (STW) propagation in solids with wavequide surface of different geometry. Studying an acoustical path of SLW propagation along axis of metallic cylindrical solid of radius R we established, that dependence of pulse amplitude vs. distance r can be approximated by fun...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

Demand for fresh water by the construction sector is expected to increase due to the high increase in the growth of construction activities in Jordan. This study aims to evaluate the potential of scale-up of the application of treated domestic wastewater in concrete from bench-scale to a full-scale. On the lab scale, concrete and mortar mixes using Primary and Secondary Treated Wastewater (PTW,...
