Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...
One of the most important purpose in breeding program is increasing grain yield per hectare. Using selection indices is the most effective methods of selection for simultaneous improvement of grain yield and related traits, which often have a quantitative inheritance. In this study, 29 rice genotypes (9 parents and 20 progenies) were evaluated. The numbers of filled grains in panicle and panicl...

We study the binary transfer learning problem, focusing on how to select sources from a large pool and how to combine them to yield a good performance on a target task. In particular, we consider the transfer learning setting where one does not have direct access to the source data, but rather employs the source hypotheses trained from them. Building on the literature on the best subset selecti...
We explore the influence of handedness and the way command selection is integrated with direct manipulation on the speed of command selection. Two empirical studies provide converging evidence that it is the merging of command selection and direct manipulation that benefits performance most, and this is especially effective in a single-handed technique. These findings provide empirical evidence...
Cultural transmission mechanisms which favor the direct transmission of the parents’ traits to their children may be adaptive to natural selection when opposed to mechanisms in which the parents choose for the offspring the highest fitness at any time. 2001 Elsevier Science B.V.

One of the effective indirect selections methods for improving grain yield and its components is the selection index. In order to develop a suitable selection index for simultaneously increasing yield and its related traits, 100 sunflower inbred lines from different geographical origins were evaluated in randomized complete block designs with three replications at Urmia University in 2015 ...
This paper presents the practical results obtained on the field from two different methods for identifying and locating leaks in water distribution systems using network modeling based algorithms. Both methods are based on the sensitivity analysis of pressure measurements to the demand variation in any node in the distribution system. This work is mainly focused on the obtained results using bo...
