The high level of energy use by domestic producers does not allow for the competitiveness livestock products in and foreign markets. Therefore, effective functioning farming enterprises requires development implementation technologies that meet world standards efficiency reduce losses. A very important energy-consuming operation is grinding feed grains (wheat, barley, peas, corn, etc.). In tech...

in this paper, we prove the existence of fixed point for chatterjea type mappings under $c$-distance in cone metric spaces endowed with a graph. the main results extend, generalized and unified some fixed point theorems on $c$-distance in metric and cone metric spaces.

a 69-year-old woman was admitted to hospital 4 times from november 2007 to june 2009. the patient had silicosis complicated by broncholithiasis, esophagobronchial fistula, and relapsed tuberculosis. she had worked as a stone crusher for 3 years and was exposed to a large amount of quartz dust. barium esophagography, gastroesophageal endoscopy, and biopsy suggested esophageal-related chronic inf...

Recently, Cho et al. [Y. J. Cho, R. Saadati, S. H. Wang, Common xed point theorems on generalized distance in ordered cone metric spaces, Comput. Math. Appl. 61 (2011) 1254-1260] dened the concept of the c-distance in a cone metric space and proved some xed point theorems on c-distance. In this paper, we prove some new xed point and common xed point theorems by using the distance in ordered con...

ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...
