‎we consider a linear programming problem in a general form and suppose that all coefficients may vary in some prescribed intervals‎. ‎contrary to classical models‎, ‎where parameters can attain any value from the interval domains independently‎, ‎we study problems with linear dependencies between the parameters‎. ‎we present a class of problems that are easily solved by reduction to the classi...

Concept lattice essentially describes the relationship between objects and attributes. The reduction of multi-value attribute concept lattice is a hot topic in the fields of information retrieval, knowledge discovery and data mining etc., while the granular computing emphasizes observing and analyzing the same problem from different granular worlds. It makes the complex problems around us be ma...

The advantages of non-prefixed marking for breast reduction are discussed in this paper. The authors use a curved incision modification of the Pitanguy technique, stressing the value of changing the demarcation depending on the skin-gland relationship of each patient.

world production of caviar from the farmed sturgeon has recently so increased that in addition to compensate reduction of natural resources of sturgeon, it has also increased its share in the world market for caviar and its substitutes. although belarus, china and norway are currently considered as the main exporting countries of caviar and its substitutes but, iran solely exports caviar from s...

harvesting corn created annually a large amount of organic waste, which could be a suitable initial substrate for vermicomposting due to its high c/n ratio. the present study was aimed for recycling of corn residues and production of good quality vermicompost, after processing by eisenia fetida. the setup of experiments was conducted with 40, 60 and 80% of corn residue, compost, cow dung and pa...

since plato is regarded as the first philosopher who started writing on aesthetics and impacted upon artistic aesthetics following him, a review of his perspective on artistic aesthetic is of crucial importance. although fine arts in its current form have not existed at the time of plato, his ideas could be discovered from what he has sporadically expressed on fine arts. there are two viewpoint...

Bidiagonal reduction is the preliminary stage for the fastest stable algorithms for computing the singular value decomposition. However, the best error bounds on bidiagonal reduction methods are of the form A + A = UBV T ; kAk 2 " M f(n)kAk 2 where B is bidiagonal, U and V are orthogonal, " M is machine precision, and f(n) is a modestly growing function of the dimensions of A. A Givens-based bi...
