In this paper, a semi-Markov model for determining the optimal time preventive replacements according to age of technical objects is presented. analyzed system transportation, due its specific characteristics, basic type renewal process carried out minimal repair. Minimal repairs in models have been literature date. studied, (sets agricultural tractors with trailers), continuous operation combi...

introduction: delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. according to icru, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. absorbed dose accuracy is investiga...

the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...

studies of rainfall variation generally focus on large areas. for example, in india, the area average monsoon rainfall series of the whole country or meteorological subdivisions are used. this would be of no use for local agriculture, particularly in places where rainfall is very high or very low, especially for crops like small cardamom and vanilla which are very sensitive to soil moisture and...

-7803-5886-4/00/$10.00© 2000 IEEE 247 one. Being converted to the chained form, a tractor and all trailers can be stabilized to desired positions via. esla.I)lished nonholonomie motion control strategies for the chained form[5, 6, 7]. S0rdalen, Naka~ mura and Chung[8] developed "t, he nonholonomic manipulator," whose kinematic model is similar to those of trailer systems. The real-world tra~jec...

The broad aim of this study was to determine whether bedding level in the transport trailer influenced pig performance and welfare. Specifically, the objective was to define the bedding requirements of pigs during transportation in commercial settings during cold and mild weather. Animals (n = 112,078 pigs on 572 trailers) used were raised in commercial finishing sites and transported in traile...

While there has been much written about various information integration technologies, there has been little said regarding how to combine these technologies together to build an entire application. In this paper, we describe the design and implementation of TheaterLoc, an information integration application that allows users to retrieve information about theaters and restaurants for cities in t...
