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...

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...

This study identifies the critical success factors that influence the acceptance of e-learning systems in developing countries. E-learning is a popularmode of delivering educationalmaterials in higher education by universities throughout the world. This study identifies multiple factors that influence the success of elearning systems from the literature and compares the relative importance amon...

This paper reports on a study of issues across the ERP life cycle from the perspectives of individuals with substantial and diverse involvement with SAP Financials in Queensland Government. A survey was conducted of 117 ERP system project participants in five closely related state government agencies. Through a modified Delphi technique, the study inventoried, synthesized, then weighted perceiv...

Fuzzy-set qualitative comparative analysis (Fs/QCA) is a social science me thod developed in order to combine case-oriented and variable-oriented quantitative analysis. It started with the creation of qualitative comparative analysis [1], with Fs/QCA later developed by applying fuzzy-set theory [2]. Although the fuzzy-set approach is still considered to be in the process of being developed [3-5...

Social research is inherently comparative (Lieberson, 1985). Researchers compare the relative effects of variables across cases; they compare cases directly with one another; and they compare empirical cases with counterfactual cases. But the comparative method – sometimes referred to as ‘smallN comparison’ – constitutes a distinctive approach to understanding social phenomena. Frequently, comp...

This article critiques the Fuzzy-set Qualitative Analysis (fs/QCA) methodology by examining its applicability in three studies in the field of comparative social policy. In each of these three test cases, I focus on the validity of fuzzy-set’s claimed function – its ability to combine theoretic discourse and evidence analysis. All three studies investigate welfare state reform in the late twent...
