Response to selection from using identified genes and quadratic indices in two-traits breeding goals
Benefits from the use of optimised selection for maximising genetic gain while constraining the rate of inbreeding were evaluated through stochastic simulation for scenarios where the breeding goal includes two negatively correlated traits. One of the traits was controlled only by polygenes and had a heritability of 0.3 while the other trait was controlled by an identified additive biallelic QT...
The gain properties of an oscillator strongly affect its behavior. When the gain is homogeneous, different modes compete for gain resources in a 'winner takes all' manner, whereas with inhomogeneous gain, modes can coexist if they utilize different gain resources. We demonstrate precise control over the mode competition in a mode locked Ti:sapphire oscillator by manipulation and spectral shapin...
Generally, the performance of a hearing-impaired child with his or her hearing aids is the major criterion in selection programmes for cochlear implantation. Thereto, it has to be considered whether the hearing-aid fitting is optimal. For this purpose, methods which prescribe hearing-aid gain are valuable, especially in young preverbal children. Three of these methods were evaluated by comparin...
In this paper we present the design process and results for a re-entry baseline controller used as a benchmarking reference within a European Space Agency (ESA) project on advanced gain-scheduling techniques. The controller is based on output gain-scheduling of a set of LTI H∞ controllers obtained using a decoupled motion approach. The rationale behind the selection of the design points, and th...
ABSTRACT Genotype by environment interaction (G×E) may exist for traits that are expressed in different environments. The G×E is often ignored the genetic evaluation of selection candidates. We hypothesized gain 2 environments always higher when true value correlation (rg) between considered evaluation. tested this hypothesis stochastic simulation dairy cattle breeding progr...
It is generally accepted that feed intake and growth (gain) are the most important economic components when calculating profitability in a growth test or feedlot. We developed a single post-weaning growth (feedlot) index based on the economic values of different components. Variance components, heritabilities and genetic correlations for and between initial weight (IW), final weight (FW), feed ...
The objective of this study was to evaluate the present conventional selection program of a swine nucleus farm and compare it with a new selection strategy employing genomic enhanced breeding value (GEBV) as the selection criteria. The ZPLAN+ software was employed to calculate and compare the genetic gain, total cost, return and profit of each selection strategy. The first strategy reflected th...
Multi-Objective Learning Automata for Design and Optimization a Two-Stage CMOS Operational Amplifier
In this paper, we propose an efficient approach to design optimization of analog circuits that is based on the reinforcement learning method. In this work, Multi-Objective Learning Automata (MOLA) is used to design a two-stage CMOS operational amplifier (op-amp) in 0.25μm technology. The aim is optimizing power consumption and area so as to achieve minimum Total Optimality Index (TOI), as a new...
To improve a complex characters such as grain yield with low heritability, indirect selection through other characters and selection index based on different effective traits were used. For this purpose, 96 F3 families derived from Roshan and Kavir crossing, together with parents, F1 and F2 progenies were cultivated. In lattice design with 2 replications under drought stress conditions in ...
