brain mr images tissue segmentation is one of the most important parts of the clinical diagnostic tools. pixel classification methods have been frequently used in the image segmentation with two supervised and unsupervised approaches up to now. supervised segmentation methods lead to high accuracy but they need a large amount of labeled data, which is hard, expensive and slow to obtain. moreove...

in this study, we investigate the further properties of quasi irresolute topological groupsde ned in [20]. we show that if a group homomorphism f between quasi irresolute topologicalgroups is irresolute at eg, then f is irresolute on g. later we prove that in a semi-connectedquasi irresolute topological group (g; ; ), if v is any symmetric semi-open neighborhood ofeg, then g is generated by v...

the polynomial interpolation in one dimensional space r is an important method to approximate the functions. the lagrange and newton methods are two well known types of interpolations. in this work, we describe the semi inherited interpolation for approximating the values of a function. in this case, the interpolation matrix has the semi inherited lu factorization.

laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...
