In this paper, we propose a low complexity clipping method to reduce the peak power of OFDM signals. The proposed clipping method exploits the conventional square clipping, which clips signal according to the amplitude in I/Q-channels separately, to avoid obtaining a real amplitude of each sample which costs relatively high computational complexities. By combining the square clipping and phase ...

one method of treating ruptured anterior communicating aneurysms is presented. this permits early clipping through a bifrontal flap. key branches of the circle of willis are temporarily occluded by special removable clips before exposing and permanently clipping the aneurysm. this requires the use of hypothermia at 28'0. and other technical aids described. the risk of a fatal recurrent hemorrha...

We present an algorithm for end to end declipping, which includes clipping detection and the replacement of clipped samples. To detect regions of clipping, we analyze the signal’s amplitude histogram and the shape of the signal in the time-domain. The sample replacement algorithm uses a two-pass approach: short regions of clipping are replaced in the time-domain and long regions of clipping are...

Clipping (i.e., harvesting aboveground plant biomass) is common in agriculture and for bioenergy production. However, microbial responses to clipping in the context of climate warming are poorly understood. We investigated the interactive effects of grassland warming and clipping on soil properties and plant and microbial communities, in particular, on microbial functional genes. Clipping alone...

Toe clipping and ear clipping (also ear notching or ear punching) are frequently used methods for individual identification of laboratory rodents. These procedures potentially cause severe discomfort, which can reduce animal welfare and distort experimental results. However, no systematic summary of the evidence on this topic currently exists. We conducted a systematic review of the evidence fo...

Keywords: Bé zier curve Curve intersection Bé zier clipping Hybrid clipping a b s t r a c t This paper presents a novel approach, called hybrid clipping, for computing all intersections between two polynomial Bé zier curves within a given parametric domain in the plane. Like Bé zier clipping, we compute a 'fat line' (a region along a line) to bound one of the curves. Then we compute a 'fat curv...

Clipping is often observed in speech acquisition, due to the limited numerical range or the non-linear compensation of recording devices. The clipping inevitably changes the spectrum of speech signals, and thus partially distorts the speaker information contained in the signal. This paper investigates the impact of signal clipping on speaker recognition, and proposes a simple yet effective clip...

the objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...

A parallel line clipping algorithm and its implementation on a parallel clipping hardware environment are presented. We first develop a simple theory to show that parallel clipping is possible for all types of line segments. We then present the architecture of a hardware environment based on which parallel clipping is to be implemented. The parallel line clipping algorithm and its implementatio...

Seasonal sucrose metabolism (sucrolysis) was studied in taproot cambial tissues of nursery-grown loblolly pine seedlings to assess the value of top clipping. In sucrose-importing taproots of nonclipped seedlings, sucrose synthase (SS) was the dominant enzyme for sucroti cleavage, and its activity exhibited a distinct seasonal activity. Both root SS activity and growth were most active during fa...
