The most popular lines clipping algorithms are Cohen-Sutherland and Liang-Barsky line clipping algorithm. These algorithms are complex and the steps of calculation are very high. This paper proposes a simple new line clipping algorithm for 2D space which uses the parametric equation of the line. This algorithm further easily extended to the polygon clipping by considering the edge of the polygo...

One of the most important operations in many graphical systems is the generation of a line segment. This process consists of two stages: clipping and drawing. These two stages are separated in current graphical applications. In this paper a new approach to line generation is proposed, which unifies these stages. The proposed algorithm is based on Bresenham’s line generation algorithm to include...

This paper is concerned with the performance improvement of PAPR reduction of orthogonal frequency division multiplexing (OFDM) signal using amplitude clipping & filtering based design. Note that OFDM is one of the well adept multi-carrier multiplexing transmission scheme which has been implemented in long term evolution (LTE) downlink. Nonetheless peak to average power ratio (PAPR) is the more...

Background: It is well known that the majority of good grade (WFNS I and II) patients who undergo microsurgical clipping achieve a favorable outcome, but still a number of patients who are independent before surgery face unfavorable outcomes signifying the impact of microsurgical clipping. The aim of this study was to quantify the risk of dependency in patients who had no previous neurological ...

Japanese beetle (Popillia japonica Newman) is an emerging silk-feeding insect found in fields in the lower Corn Belt and Midsouthern United States. Studies were conducted in 2010 and 2011 to evaluate how silk clipping in corn affects pollination and yield parameters. Manually clipping silks once daily had modest effects on yield parameters. Sustained clipping by either manually clipping silks t...

In adaptive dynamic programming, neurocontrol and reinforcement learning, the objective is for an agent to learn to choose actions so as to minimise a total cost function. In this paper we show that when discretized time is used to model the motion of the agent, it can be very important to do “clipping” on the motion of the agent in the final time step of the trajectory. By clipping we mean tha...

OBJECTIVE The presence of a cerebral aneurysm remnant after surgical clipping is associated with a risk of regrowth or rupture. For these recurred aneurysms, coil embolization can be considered as a treatment option. We retrospectively reviewed cases of ruptured or regrown aneurysms after clipping treated by endovascular coil embolization. MATERIALS AND METHODS We conducted a retrospective re...

OBJECTIVE Although surgical techniques for clipping paraclinoid aneurysms have evolved significantly in recent times, direct microsurgical clipping of large and giant paraclinoid aneurysms remains a formidable surgical challenge. We review here our surgical experiences in direct surgical clipping of large and giant paraclinoid aneurysms, especially in dealing with anterior clinoidectomy, distal...

Development of communication systems allows people to easily record and distribute their speech. The clipping-noise, however, degrades the sound quality in the speech recording when gain level of input signals is excessive in the maximum range of an amplitude. In this case, it is necessary to suppress the clippingnoise in the observed speech for improving its sound quality. Although a linear pr...

AIM Surgical outcome for giant intracranial aneurysms (GIA) is suboptimal. Reasons for higher complication rates in large and GIA surgery are the occlusion of perforators or parent arteries during aneurysm clipping, or prolonged temporary occlusion of main arteries. In this article, results of clipping of large and GIAs of anterior circulation are presented. MATERIAL AND METHODS Ten patients ...
