Mark H. Overmars§ We present an algorithm for the hidden-surface elimination problem for rectangles, which is also known as window rendering. The time complexity of OUI algorithm is dependent on both the number of input rectangles, n, and on the size of the output, k. Our algorithm obtains a hade-off between these two components, in that its running time is O(r(nI+l/T" + k», where 1 5 r :S log ...

The objective of this study was to evaluate several nonfeed removal methods compared with feed removal for induced molting of laying hens. An experiment was conducted using 576 Dekalb White hens (69 wk of age) randomly assigned to 1 of 8 dietary treatments. Two of these treatments consisted of feed removal for 10 d followed by ad libitum access to a 16% CP, corn-soybean meal diet or a 94% corn ...

The typical objective of path planning is to find the shortest feasible path. Many times, however, there may be no solution given the existence of constraints, such as obstacles. In these cases, the minimum constraint removal problem asks for the minimum set of constraints that need to be removed from the state space to find a solution. Unfortunately, minimum constraint removal paths do not exh...

Color blindness is deficiency of color vision. Due to presence of color blindness, human eye becomes unable to differentiate colors with each other. Generally reason behind color blindness is genetic but sometimes it happens due to some damage and disorder in brain and eye. Color blindness is of many types like Red-Green, Blue-Yellow etc. Red-Green color blindness is most common type of deficie...

background: one of the new methods for elimination or destruction of estrogen hormones is ultrasound irradiation. the aim of this study was to determine the main mechanism of steroid hormones removal by ultrasound. methods: in this study, estrogen (e1) and 17 beta-estradiol (e2) were irradiated with ultrasound at different frequencies, powers, and exposure times in two cases: with and without b...
