the purpose of this study is to investigate comparative advantages of corn in comparison with other competitor crops. to do so, linear programming, to 2004-2005 data related to classic index (drc) in kermanshah province was applied. results showed that corn has comparative advantages in all regions of kermanshah province while in optimal cultivation pattern of 37.5 percentages of regions in exi...

most theories in social sciences have aspects of causality, but understanding the causes of social phenomena is not possible through statistical correlation tests. to overcome this problem, fuzzy qualitative comparative analysis was developed to identify the cause of social phenomena. having qualitative roots, this method tests the necessary and sufficient causes for the emergence of a social p...

objective: a review of capability of librarianship and information science that could manifest should it be seen from a new perspective method: a historical and at the same time comparative method was used. in the historical method the field of librarianship and information science are chronicled. in the comparative method, it has been compared to other fields findings: librarianship and inform...

The advantages of modeling the unreliability of outcomes when evaluating the comparative effectiveness of health interventions is illustrated. Adding an action-research intervention component to a regular summer job program for youth was expected to help in preventing risk behaviors. A series of simple two-group alternative structural equation models are compared to test the effect of the inter...

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...

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...
