In this paper, we consider a class of quadratic maximization problems. One important instance in that class is the famous quadratic maximization formulation of the max-cut problem studied by Goemans and Williamson [6]. Since the problem is NP-hard in general, following Goemans and Williamson, we apply the approximation method based on the semidefinite programming (SDP) relaxation. For a subclas...
Adaptation of heart and lung weight to high altitudes has not been conclusively studied in bird populations of one species. Rensch (1931) concluded that the ratio of heart weight to body weight increases with altitude in certain tropical passerines. Moreau (1944), while agreeing that such a trend would be expected, maintained that Rensch’s data were unsatisfactory. Altitudinal differences in th...
BACKGROUND The Barclay cigarette (Brown & Williamson) was introduced in 1980 in the USA in the most expensive launch in history. In the USA and around the world, Barclay was later determined to have a grooved filter design that was compromised by human smokers in the normal act of smoking, but that was measured as ultra-low tar using the standard tar testing protocol. OBJECTIVES To evaluate w...
Various studies have been conducted on the topic of predicting thermal conductivity nanofluids. Here, nanofluids is determined using artificial neural networks since this approach rapid and accurate, as well cost-effective. To forecast magnetohydrodynamic Williamson flow through a vertical sheet, feed-forward network with various numbers neurons has evaluated, best based performance selected. T...
