The Persian walnut (Juglans regia L.) is one of the most valuable resources in Iran because of its multi benefits. The present study was conducted in Meshkin-Shahr in Ardabil province to investigate the important quantitative and qualitative characteristics of 31 walnut genotypes. Classification of genotypes was analyzed using the cluster method. The results showed that among selected walnut ge...

In this paper we propose an iterative hybrid heuristic approach consisting of two phases to solve the Rectangle Packing Problem. In the first phase, a strip width value W is fixed and the corresponding Strip Packing Problem is solved using an efficient hybrid GRASP-VNS heuristic. In the second one, a new value W is determined. The above phases are repeated until the stopping condition is met. T...

It is an effective method to use qualitative reasoning theory to realize sneak circuit analysis (SCA). The method using qualitative modeling combined with functional simulation to realize sneak circuit analysis. The qualitative models of resistive element, switch, transistor, MOS pipe, digital devices, analog devices, mechanical devices and other types of components were established and the qua...

This paper presents comparative analysis of counting algorithms based on image processing in LabVIEW platform. Four different algorithms are tested with cigarette packet images. A total of 100 images are chosen for comparison. Different qualities of images are considered like good image, low light image, out of focus image, and extra bright image. An 80% matching with the template is considered...

Cognitive developmental psychology often describes children’s growing qualitative understanding of the physical world. Physics educators may be able to use the relevant methods to advantage for characterizing changes in students’ qualitative reasoning. Siegler developed the “rule assessment” method for characterizing levels of qualitative understanding for two factor situations (e.g., volume an...

there are different methodes for performance evaluation of economic development plans and ranking them in comparison with each other. these methods are founded on both quantitative and qualitative approaches. however, real world events are based upon uncertainty and since quantitative methods, unlike their names, are not accurate enough, they do not seem to be efficient in qualitative decision-...
