bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
Prediction of daily evaporation is a valuable and determinant tool in sustainable agriculture and hydrological issues, especially in the design and management of water resources systems. Therefore, in this study, the ability of artificial intelligence models of multi-layer perceptron (MLP), support vector regression (SVR), and the hybrid model of support vector regression-firefly optimization a...
In this research, applied synoptic model for determining the average daily temperature and its relationship with the Geopotential Height in middle level (500 HPa). Therefore, two database were used: database of atmospheric circulations, includes the data of geopotential height at 500 HPa and its data were extracted from the NCEP/DOE(US National Oceanic and Atmospheric Administration) in hours 0...
OBJECTIVE Numerous published reports have linked various disease states and pregnancy-related conditions with meteorologic factors such as weather, humidity, and temperature. The purpose of this study was to determine if temperature and dew point affect the incidence of pyelonephritis during pregnancy. METHODS A retrospective chart review of a 4-year period from 1989 to 1992 was performed. Th...
For point sets in the rectilinear plane we consider the following five measures of the interconnect length and prove bounds on the worst-case ratio: minimum Steiner tree, minimum star, clique, minimum spanning tree, and bounding box. In particular, we prove that for any set of n points: (n − 1) times the shortest Steiner tree is less or equal to the clique unless n = 4; and the minimum spanning...
Since Gallager, Humblet and Spiru first introduced the distributed Minimum Spunning Tree problem, many authors have suggested ways to enhance their basic algorithm to improve its performance. Most of these improved algorithms have even been shown to be very eficient i n terms of reducing their worst-case communications and/or t ime complexity measures. In this paper, however, we take a differen...
KuhSefid Flourite deposit is located about 110 km south east of Mashhad. Geological units of the region related to Kashafroud Formation with Jurassic age. Most of fluorite mineralization can be seen along the faults with direction of north west-south east. Fluorite veins are differente in diameter of 2 to 2.5 m and length of 50 m. Hydrothermal solutions with maximum and minimum temperatures of ...
The purpose of this study was to investigate the effect of voltage, salinity and temperature on the performance of electrofishing. Number 850 pcs Capoeta capoeta of Chehel Chay river of Golestan province fishing and transported to the laboratory. Distance from the anode, cathode and anode distance during testing, respectively, 10 cm and the 120 cm. Range of length and weight of the fish test sp...
