The work is devoted to the problem of comparing objects by color. following statement considered: among set it necessary find such an object, color which most similar given object. It assumed that for each object only its spectrum (transmission, reflection, radiation) known, exhaustive characteristic In addition, radiation source be known. use standard methods determining differences has shown ...

Multi-criteria decision making is used in many areas of human activities. Each alternative in multi-criteria decision making problem can be described by a set of criteria. Criteria can be qualitative and quantitative. They usually have different units of measurement and different optimization direction. The normalization aims at obtaining comparable scales of criteria values. The normalization ...

Dimensional analysis, for multi-criteria decision making, is a mathematical method that includes diverse heterogeneous criteria into a single dimensionless index. Dimensional Analysis, in its current definition, presents the drawback to manipulate fuzzy information commonly presented in a multi-criteria decision making problem. To overcome such limitation, we propose two dimensional analysis ba...

this experiment was conducted to determine the effect of using l-threonine and reducing dietary levels of crude protein (cp) on egg production criteria in layers. three hundred of hy-line w36 laying hens were used in this experiment. this experiment consisted of three experimental treatments with five replications in each. experimental treatments included 3 diets with different levels of cp whi...

Systems of selective distribution involve essentially two elements. First, the distribution does not supply every dealer, retailer, or wholesaler who is willing to sell the products in question. Only those who meet certain criteria are appointed as authorized retailers or wholesalers. Second, authorized dealers may sell only to other authorized dealers, or, in the case of retailers, to users. I...

BACKGROUND There are important gaps in our understanding of the epidemiology and diagnosis of upper-airway obstruction. METHODS We examined the diagnostic value of several criteria for predicting upper-airway obstruction, and we measured the frequency of detecting upper-airway obstruction via quantitative and visual assessment of flow-volume loops. We studied 4 quantitative and 3 visual crite...

This paper explores quantitative evaluation criteria for service and potentials of new service from the transportation viewpoint. For this purpose, we analyze transport networks of railway, subway, and waterbus, and have revealed the following implications: (1) efficiency criterion proposed by Latora [7, 8] and centrality criterion in the complex network literature can be applied as quantitativ...
