In this study, an industry terminal breeding goal was used in a deterministic simulation, using selection index methodology, to predict genetic gain in a beef population modelled on the UK pedigree Limousin, when using genomic selection (GS) and incorporating phenotype information from novel commercial carcass traits. The effect of genotype-environment interaction was investigated by including ...

This report presents the development of the Gain Weighted Eigenspace Assignment methodology. This provides a designer with a systematic methodology for trading off eigenvector placement versus gain magnitudes, while still maintaining desired closed-loop eigenvalue locations. This is accomplished by forming a cost function composed of a scalar measure of error between desired and achievable eige...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...

Variable-speed, horizontal axis wind turbines use bladepitch control to meet specified objectives for three regions of operation. This paper focuses on controller design for the constant power production regime. A simple, rigid, non-linear turbine model was used to systematically perform trade-off studies between two performance metrics. Minimization of both the deviation of the rotor speed fro...

This paper proposes a dielectric slabs-based lens for millimeter-wave beamforming systems. The proposed is based on the graded steps of effective refractive index semi-spherical lens. It consists multiple slabs that match selected gradient index. These have same thicknesses and different radii. slab thickness in this should not exceed quarter operating wavelength to keep similar original A horn...

Meat was originally produced from non-specialized animals that were used for a variety of purposes, in addition to being a source of food. However, selective breeding has resulted in “improved” breeds of cattle that are now used to produce either milk or beef, and specialized chicken lines that produce eggs or meat. These improved breeds are very productive under appropriate management systems....

this study was evaluated some strategies and determined the suitable selection index for afshari sheep using simulated data. the relative importance of traits was determined based on the estimated economic values and consequently, the most benefit traits were applied to selection indexes construction. the interest indexes were different combination of traits including ewe body weight (ebw), ann...

ecent experimental results [1,2] suggest that optical fiers having a negative index step from cladding to core, ombined with an adequately large gain coefficient in a arge-diameter core region, can provide robust single ransverse mode operation having very large mode area ithout requiring complex fiber structures or other mode iscrimination measures. This paper reviews the imporant mode propert...
