The concept of surgical revascularization for coronary artery disease (CAD) originated in the early 20th century. A pioneer in this field is Beck, a surgeon who in 1935 developed an indirect technique of myocardial revascularization by grafting a flap of the pectoralis muscle over the exposed epicardium to create new blood supply. [1] Later, Beck also developed another revascularization techniq...

Hough transform is a popular low-level computer vision algorithm. Its computationally effective modification, Fast Hough transform (FHT), makes use of special subsets of image matrix to approximate geometric lines on it. Because of their special structure, these subset are called dyadic patterns. In this paper various properties of dyadic patterns are investigated. Exact upper bounds on approxi...

In the past decade there has been increased support from governments, NGOs and donor agencies for collective livelihood interventions organised by poor women. This support is largely in response to two assumptions: first, that collective enterprises are an effective buffer for the economic vulnerability of poor women, particularly since market liberalisation has made the livelihoods of individu...

Aggregates constitute major part of the pavement structure. The engineering properties of the aggregates, as well as its shape (i.e. form and angularity) and texture, substantially affect the overall performance of the pavement (Kuo and Freeman 1998, Maerz 2004). A number of researchers reported that form and surface texture of aggregates have significant effect on the mechanical property of th...
