Recent applications and developments based on support vector machines (SVMs) have shown that using multiple kernels instead of a single one can enhance classifier performance. However, there are few reports on performance of the kernel‐based Fisher discriminant analysis (kernel‐based FDA) method with multiple kernels. This paper proposes a multiple kernel construction ...

This study examines the relationships between atmospheric influences and grain yields as well as yield components: crop density (ears m−2), number of kernels per ear and kernel weight of winter rye. The study uses data of a long-term field experiment at Berlin-Dahlem for the period between 1962 and 1996. The crop density and kernel number of winter rye were positively influenced by warm and sun...

background in a severe oxidative stress condition, balance of oxidant-anioxdiant system of the body breaks down, which is in order to produce more oxidants and, after that, important macromolecules such as dna undergo irreversible changes. there are reports indicating the therapeutic effects of the date. this study was aimed to evaluate the effect of date kernel`s on antioxidant capacity and th...

in order to evaluate some morphological traits of durum wheat genotypes, 18 elite lines selected from advanced regional durum wheat yield trials. these materials along, with two checks dena (durum wheat) and parsi (bread wheat) were examined using rcb design with three replications at isfahan research station in two consecutive cropping season. during the cropping season some trials such as the...

This paper proposes an efficient method of sentence retrieval based on syntactic structure. Collins proposed Tree Kernel to calculate structural similarity. However, structual retrieval based on Tree Kernel is not practicable because the size of the index table by Tree Kernel becomes impractical. We propose more efficient algorithms approximating Tree Kernel: Tree Overlapping and Subpath Set. T...

Knowledge of maize (Zea mays L.) kernel weight (KW) and number (KN) response to nitrogen (N) fertilization can help understand the physiological basis behind overall grain yield N fertilizer, but such data are rare. To fill this gap, we studied how KN KW respond fertilization. We first analyzed its components in 23 field experiments (site × year combinations) from Argentina United States. Secon...
