In this study, we propose a three-stage weighted sum method for identifying the group ranks of alternatives. In the first stage, a rank matrix, similar to the cross-efficiency matrix, is obtained by computing the individual rank position of each alternative based on importance weights. In the second stage, a secondary goal is defined to limit the vector of weights since the vector of weights ob...

Albanian Sign Language (AlbSL) is relatively new and until now there doesn’t exist a system that is able to recognize Albanian signs by using natural user interfaces (NUI). The aim of this paper is to present a real-time gesture recognition system that is able to automatically recognize number signs for Albanian Sign Language, captured from signer’s both hands. Kinect device is used to obtain d...

It is well known that fluorescent traffic sign have a daytime conspicuity that is far superior to that of normal color signs. This study was conducted in order to test the hypothesis if adding the property of fluorescence while leaving all (or in practical terms most) other sign features the same, does in fact increase the legibility distance. Six diamond shaped signs were fabricated and lamina...

The conspicuity of traf ic signs is crucial, as their purpose to give drivers with direction and information. ef ectiveness iciency a sign determined by its visibility, legibility, veracity information for observers. This study recruited primarily postgraduate students participants. assessment was conducted part controlled experiment. Method used in this research indoor experiment using visual ...

introduction: leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. as a consequence, the use of filter technology for leukoreduction has been widely practiced .according to aabb accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...
