Remarks on Separation of Convex Sets, Fixed-Point Theorem, and Applications in Theory of Linear Operators
(Springer International Publishing Ag, 2007)Some properties of the linear continuous operator and separation of convex subsets are investigated in this paper and a dual space for a subspace of a reflexive Banach space with a strictly convex norm is constructed. Here ... -
Removal Of Cr(Vi) From Wastewater Through Glycine Assisted Synthesis Of Tio2
(2019)In this study, titanium dioxide was synthesized via solution combustion method. Titanium(IV) oxysulfate was used as a titanium source. The fuel type, reaction time, and reaction temperature were tested for optimization. ... -
Revision Of The Species Composition And Distribution Of Turkish Sand Flies Using Dna Barcodes
(2019)Background Currently, knowledge regarding the phlebotomine sand fly (Diptera: Psychodidae) fauna of Turkey is restricted to regions with endemic leishmaniasis. However, rapidly changing environmental and social conditions ... -
Rhodotorula Mucilaginosa Dan Lipaz Enzimi Üretimi ve Aktivitesine Etkili Parametrelerin Belirlenmesi
(Fen Bilimleri Enstitüsü, 2014)Lipases (E.C.3.1.1.3; tri glycerol acyl hydrolases) are hydrolizer enzymes which catalyze free fat into glycerol and triglycerid. Industrial lipase commonly is provided by external cellular activity from strains of ... -
Ricotia L. (Brassicaceae) Cinsinin Filogeni ve Filocoğrafyası
(Fen Bilimleri Enstitüsü, 2015)In this study, phylogeny and phylogeography of genus Ricotia L. (Brassicaceae), which is represented by nine species in eastern Mediterranean Region, is examined. Assigning Ricotia into a particular tribe, which has not ... -
Riesz Uzayları Üzerinde Tanımlı Sıra Kompakt ve Sınırsız Sıra Kompakt Operatörler
(Fen Bilimleri Enstitüsü, 2020-08-28)Order convergence and unbounded order convergence are not topological terms on Riesz space. On the other hand, compact operatör takes an important place in functional analysis. In this thesis, we investigate order compact ... -
Riesz Uzaylarında Netlerin Yakınsaklıkları Üzerine
(Fen Bilimleri Enstitüsü, 2023)Banach lattices can be equipped with many convergence structures such as order, relative regular, unbounded order, unbounded norm convergence, and absolutely un bounded weak convergence. While some of these convergences ... -
Rings Close to Semiregular
(Korean Mathematical Soc, 2012)A ring R is called semiregular if R/J is regular and idempotents lift modulo J, where J denotes the Jacobson radical of R. We give some characterizations of rings R such that idempotents lift modulo J, and R/J satisfies ... -
Rings Whose Cyclic Modules Are Direct Sums Of Extending Modules
(Cambridge Univ Press, 2012)Dedekind domains, Artinian serial rings and right uniserial rings share the following property: Every cyclic right module is a direct sum of uniform modules. We first prove the following improvement of the well-known ... -
Rings Whose Modules Are Circle Plus-Supplemented
(Academic Press Inc, 1999)We prove that a ring R is serial if and only if every finitely presented right and left R-module is circle plus-supplemented, and that R is artinian serial if and only if every right and left R-module is circle plus-supplemented. ... -
Rings Whose Pure-Injective Right Modules Are Direct Sums of Lifting Modules
(Academic Press Inc Elsevier Science, 2013)It is shown that every pure-injective right module over a ring R is a direct sum of lifting modules if and only if R is a ring of finite representation type and right local type. In particular, we deduce that every left ... -
Risk Analizinde Bulanık Mantığın Kullanılmasına Yönelik Bir Uygulama Çalışması
(Fen Bilimleri Enstitüsü, 2018)In order to be able to produce solutions to the problems we face in our daily lives, researchers are trying to transfer the focused processes to analysis systems as realistically as possible. The success of implementation ... -
Risk Measurement Using Time Varying Extreme Value Copulas
(Fen Bilimleri Enstitüsü, 2021)This thesis aims to estimate reliable risk measures by considering the dependent and heavy-tailed characteristics of the different insurance risk branches. Thus, it is aimed to model the skewed and heavy-tailed data more ... -
Robust Model Selection Criteria For Robust S And Lts Estimators
(Hacettepe Univ, Fac Sci, 2016)Outliers and multi-collinearity often have large influence in the model/variable selection process in linear regression analysis. To investigate this combined problem of multi-collinearity and outliers, we studied and ... -
Bir rüzgar çiftliğinden yapay sinir ağlarıyla kısa süreli elektrik üretim tahmini
(Fen Bilimleri Enstitüsü, 2018)In recent years, wind energy systems become an important source for energy production around the world with increasing installations. When Turkey’s wind energy potential is taken into consideration, wind energy systems ... -
Sağlam Kestiricilere Dayalı Varyans Analizi
(Fen Bilimleri Enstitüsü, 2023)Certain assumptions must be provided in the Analysis of Variance (ANOVA) calculated over sample means. If the assumptions are not met, the Analysis of Variance cannot fully reveal the real group differences, and in this ... -
Sağlam Kısmi En Küçük Kareler Regresyonu
(Fen Bilimleri Enstitüsü, 2014)Partial Least Squares Regression (PLSR) method is a Latent Variables (LVs) regression method. Therefore, in this method, firstly, a set of unrelated LVs is predicted and then, the relationship of these LVs with dependent ... -
Salt Resistance of Tomato Species Grown in Sand Culture
(Czech Academy Agricultural Sciences, 2010)In this study, Na+, Cl-, K+, Ca2+, chlorophyll and proline levels and the rate of lipid peroxidation level in terms of malondialdehyde (MDA), were investigated in tissues of 15 different tomato cultivars in salt tolerance. ... -
