Automatic identification and removal of low quality online information
… launch these attacks by deliberately inserting low quality information into information-rich environments to promote that information or to deny access to high quality information. These attacks directly threaten the usefulness and dependability of online information-rich environments, and as a …

Hybrid Words Representation for the classification of low quality text
… question we must address is how to improve the low-quality text. The next immediate challenge is to have the best representation so that text can be classified accurately. The way text is organized reflects polysemy, semantic and syntactical coupling relationships which are embedded in its …

Individual recognition from low quality and occluded images and videos using GAN
… the problem of recognising degraded faces from low-quality images and videos mostly remains unsolved. In recent times, we have seen a breakthrough in the perceptual quality of image enhancement with the recovery of the fine texture details and sharpness of degraded images. Several …

Low Quality Roughages in High-Concentrate Pelleted Diets for Sheep and Lambs
Studies were conducted to evaluate factors affecting utilization of certain roughages in high-concentrate pelleted diets formulated for sheep.

A literature review on low–quality waste heat recovery in residential and commercial settings
… this literature review is to evaluate proposed low quality waste heat recovery systems in residential and commercial settings. The basics and limitations of these systems are outlined with attention directed towards identifying new systems with promise.

Even-aged regeneration alternatives for low quality oak hardwood forests in the Virginia Piedmont
The effects of site quality, dormant and growing season harvests, and four even-aged regeneration treatments on natural hardwood and planted loblolly pine (Pinus taeda L.) are examined three years after clear felling and whole-tree harvesting upland hardwood stands in the Virginia Piedmont. Natural …

Fermentation characteristics, nutritional value and palatability of ensiled seafood wastes and low quality roughages
… acid was added to the crab waste mixtures to lower the initial pH to 4.5. After ensiling all mixtures containing fish and straw showed a decrease in pH. Addition of acetic acid to mixtures containing crab waste inhibited fermentation, but resulted in a very stable product. In a sheep digestion …

Urea supplementation in rumen and post-rumen for cattle fed a low-quality tropical forage
… kinetics and urea transporters in heifers fed a low-quality tropical forage. Five heifers (283±23 kg, Body Weight, BW) were fitted with rumen and abomasum fistulas and assigned to a 5 ×5 Latin square design. The treatments were: control (only forage), continuous infusion of urea in the abomasum …

Extraction of surface texture data from low quality photographs to aid the construction of virtual reality models of archaeological sites
A tool has been designed and implemented to use information extracted from photographs captured using uncalibrated cameras (so-called casual photographs) to fill the occlusions which occur in three-dimensional models of photogrammetrically captured sites. Capturing the geometry of archaeological …

Degenerate Oligonucleotide Primed - Polymerase Chain Reaction Evaluation And Optimization To Improve Downstream Forensic STR Analysis Of Low Quality/Low Quantity DNA
When forensic biological samples yield low quality/low quantity DNA, thecurrent STR analysis methods do not generate acceptable profiles. Whole genomeamplification can be used to pre-amplify the entire genome for downstream analyses. A commercially available kit for DOP-PCR, a form of WGA, is …

Multigrid methods for complex engineering geometries and unstructured meshes
… methods decays significantly if locally poor quality cells are present, and it is found that the poor convergence is due to the local failure of the smoothing property. The high frequency error localised in regions of low quality cells is not eliminated by standard multigrid smoothers and …

Breast Cancer Prevention Educational Interventions in Young Women : A Systematic Review
… selected the studies, appraised methodological quality, and rated the quality of the evidence using the GRADE approach. Results: We included (900 women). One randomized-controlled trial (RCT) from Canada (745 women) and one uncontrolled trial from Colombia (N=155). Both studies were conducted in …

RECONSTRUCTION MODELS TO IMPROVE IMAGE QUALITY
… in health care, where the physician needs a high-quality image of the patient in order to make better decisions or to perform surgery. Breath-holding MRI scanners have high-acquisition speed and collect a large number of low-quality frames; similarly, some surveillance cameras have low acquisition …

Evaluation of page quality using simple features
A classifier to determine page quality from an Optical Character Recognition (OCR) perspective is developed. It classifies a given page image as either "good" (i.e. high OCR accuracy is expected) or "bad" (i.e., low OCR accuracy expected). The classifier is based upon measuring the amount of white …

Effect of nitrogen and energy supplementation on intake, digestibility and rumen fermentation efficiency in sheep fed poor quality Eragrostis curvula hay
… microbial nitrogen synthesis (MNS) in sheep fed low-quality Eragrostis curvula hay (< 3% CP, 80% NDF; DM basis). In Trial 1, urea partially substituted the rumen degradable nitrogen (RDN) fraction of sunflower meal (SFM). Neutral detergent fibre (NDF) digestibility was higher in the treatments …

Nutritional implications of coprophagy and cecal function in two microtine rodents (Microtus pennsylvanicus and Microtus pinetorum)
… and the pine vole (Microtus pinetorum) as diet quality was manipulated. The nutritional response of the voles to a high and low quality diet was measured after the coprophagic or cecal component was eliminated from the digestive process. The nature of the nutritional response was determined by …
