A cycle double cover (CDC) of an undirected graph is a collection of the graph’s cycles such that every edge of the graph belongs to exactly two cycles. We describe a constructive method for generating all the cubic graphs that have a 6-CDC (a CDC in which every cycle has length 6). As an application of the method, we prove that all such graphs have a Hamiltonian cycle. A sense of direction is ...

In music structure analysis the two principles of repetition and homogeneity are fundamental for partitioning a given audio recording into musically meaningful structural elements. When converting the audio recording into a suitable self-similarity matrix (SSM), repetitions typically lead to path structures, whereas homogeneous regions yield block structures. In previous research, handling both...

Land degradation is one of the most serious problems facing resource-poor tropical hillside farmers. Studies examining determinants of farmers’ decisions to invest in land improvement technologies have focused on economic and financial factors, neglecting individuals’ perceptions and awareness of the problems and how they affect land use and behavioral change that enhance environmental sustaina...

In flow visualization, integral surfaces are of particular interest for their ability to describe trajectories of massless particles. In areas of swirling motion, integral surfaces can become very complex and difficult to understand. Taking inspiration from traditional illustration techniques, such as cut-aways and exploded views, we propose a surface analysis tool based on surface splitting an...

The role of talent and creativity in economic development has been a subject of growing interest to social scientists. Human capital is observed both to be an important contributor to growth and to be unevenly distributed geographically. While there is consensus on the importance of human capital to economic development, debate takes shape around two central issues. First, there is the question...

the purpose of this study was to describe the association between grain yield and its components. the experiment was conducted in a randomized complete block design with three replicatsions. results of analysis showed that similar trends were observed for genotypic and phenotypic correlations and in most cases, the value for genetic correlation was greater than phenotypic value. 100-seed weight...

background: type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. the hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. however, there is no consensus on the defini...
