The objectives of this study were to analyze the trend of within-breed genetic diversity and identify major causes leading to loss of genetic diversity in Guernsey breed in three countries. Pedigree files of Canadian (GCN), South African (GSA) and American (GUS) Guernsey populations containing 130 927, 18 593 and 1 851 624 records, respectively, were analyzed. Several parameters derived from th...

Automatic voltage regulator; Gravitational search algorithm; Load tracking performance; Opposite number; Optimization; Sugeno fuzzy logic Abstract The design and performance analysis of a Sugeno fuzzy logic (SFL) controller for an autonomous power system model is presented in this paper. In gravitational search algorithm (GSA), the searcher agents are collection of masses and their interactions...

Root and shoot branches are major determinants of plant form and critical for the effective capture of resources below and above ground. These branches are often maintained at specific angles with respect to gravity, known as gravitropic set point angles (GSAs). We have previously shown that the mechanism permitting the maintenance of non-vertical GSAs is highly auxin-dependent and here we inve...

Automatic Generation Control (AGC); Proportional Integral Derivative Controller; Gravitational Search Algorithm (GSA); Governor dead-band nonlinearity; Generation Rate Constraint (GRC); Sensitivity Abstract An attempt is made for the effective application of Gravitational Search Algorithm (GSA) to optimize PI/PIDF controller parameters in Automatic Generation Control (AGC) of interconnected pow...

While the mechanisms of tumorigenesis for adrenocortical neoplasms remain unknown, several genes, such as Gsa, ACTH receptor (MC2-R), p53, and p16 tumor suppressor genes, are considered to be candidates for adrenocortical neoplasms. Mutation analysis studies have documented these genes in adrenocortical neoplasms, but these studies focused on the mutation of only one of these genes. In the pres...

Page 7020, Figure 5. The reported molecular hydrophobicity potential (MHP) values of the carbonylated residues aminoadipic semialdehyde (Asa) and glutamic semialdehyde (Gsa) were calculated using a different procedure than MHP values of canonical residues. Briefly, the former were calculated for amino acid side chain analogs, while the latter were calculated for complete amino acids with subseq...

ystem identification is mainly the process of improving a mathematical modeling of a physical system using experimental data. In this paper, a new hybrid wavelet neural network is proposed for the system identification purposes. The Gravitational Search Algorithm (GSA) is a new evolutionary algorithm which recently introduced and has a good performance in different optimization problems. The GS...
