Calculations of the effects of peak clipping on speech-like signals
Peak clipping is a well known method of increasing the average power of a peak power limited voice communication transmitter. Although the clipping process introduces distortion, articulation tests have shown that clipped speech remains highly intelligible. Using idealizations of vowel sounds based …

Effects of three clipping managements on growth and production of a Kentucky bluegrass-clover sward
The effect of three clipping managements on the growth and production of Kentucky bluegrass was investigated at the West Virginia University Livestock Farm. Herbage accumulation, botanical composition, leaf extension rate (LER), leaf appearance rate (LAR), and tiller density were observed. The …

Cognitive outcome of aneurysmal subarachnoid haemorrhage after clipping or coiling : a comparative post intervention study in a hospital population
… secondary to ruptured cerebral aneurysm and clipping are associated with substantial morbidity and mortality. Despite favourable neurological outcomes, many patients report persistent cognitive and emotional deficits post intervention. To compare cognitive and quality of life outcomes in …

Intersection Algorithms Based On Geometric Intervals
… interval to extend the technique of Bézier clipping. A geometric interval is used to tightly bound a curve or surface or to contain a point on a curve or surface. Our algorithms retain the desirable characteristics of the Bézier clipping technique such as ease of implementation and the …

Phenological and Cultural Studies of Common Dandelion (Taraxacum officinale Weber)
… (Poa pratensis L.). Sub-treatments were: 1) no clipping, 2) clipping at 4 cm each week, 3) clipping at 4 cm every two weeks, 4) clipping at 8 cm each week, and 5) clipping at 8 cm every two weeks. Sod competition significantly reduced both the number of reproductive stems and the diameter of …

Complexity reduction in multiple input multiple output algorithms
… issues of this algorithm. One such issue, clipping of the Analog to Digital Converter (ADC) at the receiver, is described in the first part of the thesis (chapter 3). A small amount of clipping in an ADC can improve dynamic range and reduce the power consumption. However, the increased …

Investigating the role of epigenetics in rapid adaptation to stress in Arabidopsis thaliana and Sorghum bicolor
… doses of glyphosate, trifloxysulfuron, clipping, and shading, which we further classified into the broader categories of stress ecological (shading and clipping) and herbicides (glyphosate and trifloxysulfuron). We analyzed phenotypic and whole-genome bisulfite sequencing data and found …

Response of marula to simulated browsing on a productivity gradient
… productivity gradient. Browsing was simulated bu clipping the saplings at a range of intensities and a productivity gradient was achieved by applying fertiliser at a range of levels. The interaction between clipping and fertiliser treatments had a significant effect in explaining final tree heigh …

Single-ended non-intrusive speech quality monitoring in VoIP
… major impairments in VoIP, including temporal clipping, echo, packet loss and noise, are investigated in the thesis.To model the effects of temporal clipping on speech quality, an algorithm based on the clipping statistics is developed, with different weighting factors assigned to different …

Shape Up: Peak -Power Reduction via Constellation Shaping
… to that of conventional systems. With a clipping rate of 10-8, they still provide up to 2.8 dB of peak-power reduction. Algebraic shaping reduces the unclipped peak power by 8 to 10 dB and about 2.9 dB at a clipping rate of 10-8 for 16-channel systems. Moreover, algebraic shaping …

On the other hand, there is no concurrency control protocol designed for linear spatial indexing structures, where the one-dimensional concurrency control protocols cannot be directly applied. Furthermore, …

Nitrogen cycling in tall fescue turf with added clippings
Grass clippings may be recycled onto nearby areas of turf as an alternative to disposal of clippings in landfills. In May, 1991, two field studies were initiated to evaluate grass clippings as a nitrogen (N) source for tall fescue (Festuca arundinacea, Schreb. Rebel’) turf, and to determine the …
