in order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the doroud parks and landscape organization, located in doroud, lorestan, iran. the first factor was the concentration of sport turfgrass clipping extract...

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...

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...

We propose clipping methods that are capable of using complex geometries for volume clipping. The clipping tests exploit per-fragment operations on the graphics hardware to achieve high frame rates. In combination with texture-based volume rendering, these techniques enable the user to interactively select and explore regions of the data set. We present depth-based clipping techniques that anal...

In this research paper, a variation of clipping ,RCF and tone reservation/injection techniques are examined with proper analysis of clipping ratio (CR) and depth factor(Alpha) in fine tuning of a PAPR reducing system. By exploiting the sparsity of clipping events in the time domain relative to predefined clipping threshold and generate the OFDM bins of the incoming broadband channel into narrow...

The high peak-to-average power ratio (PAR) in Orthogonal Frequency Division Multiplexing (OFDM) modulation systems can significantly reduce performance and power efficiency. A number of methods exist that combat large signal peaks in the transmitter. Recently several methods have emerged that alleviate the clipping distortion in the receiver. We analyze the performance of two receiver clipping ...
