Since there is no single method available for solving all economic dispatch problems efficiently, thus a number of different optimization methods have been developed to solve this problem. These techniques were divided into three types depending on the efficiency of the solution: stochastic process techniques, statistical methods, and mathematical programming techniques which divided to local optimization, and global optimization. It is found that is better to use hybrid techniques to overcome load dispatch problems so as to achieve significant improvements in computation time, convergence properties, solution quality, or parameter robustness.","PeriodicalId":158972,"journal":{"name":"Sudanese Online Research Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130403236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GATA2 protein is encoded by the GATA2 gene which often suffers germ line and somatic mutations which lead to a wide range of familial and sporadic diseases. Association of data including protein and genetic interactions, pathways, co-expression, co-localization and protein domain similarity were predicted using Gene MANIA software. This gene was investigated in NCBI database and the Non-Synonymous Single Nucleotide Polymorphisms (nsSNPs) were analyzed by computational software, (SIFT, PROVEAN, Polyphen-2, SNPs & GO, PHD-SNPs, I-Mutant and MUpro). The Protein structural analysis was done by modelling of amino acid substitutions using Project Hope for all predicted pathological polymorphisms. GeneMANIA results showed that GATA 2 gene was associated with 20 other genes. It interacts mainly with ZFPM1 gene (Zinc Finger Protein), FOG family member 1and HDAC5 histone deacetylase5. A total of 246 nsSNPs were obtained from the SNPs database in NCBI consisting of 47 Deleterious predicted by SIFT software. Using PROVEAN 41 SNPs were predicted to have deleterious effect, 17 SNPs were predicted to be damaging by (Polyphen- 2), while 4 SNPs were benign, 14 SNPs were found to be disease related using SNPs&GO and 30 SNPS were found to be disease related using PHD- SNP. By using I-MUTANT and MUPRO software the stability of the protein was predicted. From the results of SIFT, PROVEAN and PolyPhen-2 with respect to PHD-SNPs and SNPs&GO software programs, 6 nsSNPs (rs148942346 (R344I), rs371096438 (P385N), rs387906629 (R398W), rs387906629 (R384W), rs387906633 (C359R) and rs387906633 (C373R)) were predicted to be deleterious, damaging, affecting the protein stability and related to the formation of a disease variants.

The models were applied to some selected economically important natural tree species common to central Sudan, namely, Combretum hartmannianum and, Lonchocarpus Laxiflorus. The tree variables measured were the diameter at breast height (DBH, cm), diameter at the base of the tree (d0, cm), upper stem diameters (di), total tree height (H), and height to the base of the crown (Hb). In total, 19 taper and 32 volume models were tested and evaluated (22 models were two-variable models (Diameter at breast height and total tree height or bole height) and 10 were three-variable models (Diameter at ground level, Diameter at breast height and total tree height or bole height). The model goodness of fit was evaluated in terms of adjusted coefficient of determination (Ra2), standard error (SE), mean absolute residual (MAR), bias (BI) Akaike’s information criterion (AIC), homogeneity of the residuals and significance of the regression parameters. \u0000As far as taper models is concerned, Models, some of the models were found to yield satisfactory results for the tow selected species with R2 range of 0.94 – 0.96. For the within species variation of models on the basis of the AIC values, the ranking of the models (smaller AIC first) were in consistant with the rankings due to SE and Ra2 values although AIC penalizes models in proportion to the number regression parameters. In general the results of the study indicated that higher residuals valuse are in most of the cases associated with the lower parts of the bole, the butress portion of the stem. This suggests that care should be taken during the application of such models for hardwood species, especially in open woodlands where butress is a common characteristic.The results for volume models revealed differences in the behaviour of different models for each species as the degree of significance of the regression parameters varies between tree species. However, the replacement of the total tree height by the bole height (merchantable height) improves both the level of parameter significance and the coefficient of determination. The results also reveal that inclusion of diameter at grown level to the original two variables (DBH, Ht) and the replacement of the original model total height with the bale height results in quite significant improvement of the Ra2 values. In general, the study concluded that taper and volume models can provide precise and accurate estimation of tree growth variables for the studied species with reasonable cost and time, but care should be taken when dealing with same model for the same species across varying growth and management condition, or when dealing with different species. country.","PeriodicalId":158972,"journal":{"name":"Sudanese Online Research Journal","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131651311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
