alpha-INCLUSIONS APPLIED TO GROUP THEORY VIA SOFT SET AND LOGIC
(ANKARA UNIV, FAC SCI, 2019)Soft set theory, initiated by Molodtsov, is a tool for modeling various types of uncertainty. In this paper, upper and lower alpha-inclusions of a soft set are defined. By using these new notions, some analyzes with respect ... -
ON A NEW VARIATION OF INJECTIVE MODULES
(ANKARA UNIV, FAC SCI, 2019)In this paper, we provide various properties of GE and GEE-modules, a new variation of injective modules. We call M a GE-module if it has a g-supplement in every extension N and, we call also M a GEE-module if it has ample ... -
Semiparallel Submanifolds of a Normal Paracontact Metric Manifold
(HACETTEPE UNIV, FAC SCI, 2019)The object of the present paper is to study invariant semiparallel and 2-semiparallel submanifolds of a normal paracontact metric manifold. We see that parallel submanifolds of a normal paracontact metric manifold are ... -
A novelty optimization approach for drilling of CFRP nanocomposite laminates
(SPRINGER LONDON LTD, 2019)Numerous problems are encountered in drilling of carbon fiber-reinforced polymer composite materials (CFRP) such as delamination, tool wear etc. Delamination has been recognized as a major damage encountered when drilling ... -
Prostate volume effect on Gleason score upgrading in active surveillance appropriate patients
(PAGEPRESS PUBL, 2019)Introduction: Gleason Score (GS) upgrading rates in the literature are reported to be around 33-45%. The relationship between prostate volume and GS upgrading should be defined, aiming to reduce upgrading rates in patients ... -
An Examination of the Relations Between Symptom Distributions in Children Diagnosed with Autism and Caregiver Burden, Anxiety and Depression Levels
(SPRINGER, 2019)High stress levels and impairment of physical/mental health in parents can delay early and effective intervention in autism. The purpose of this study was to examine relations between the clinical characteristics of children ... -
The examination of molecular structure properties of 4,4 '-oxydiphthalonitrile compound: combined spectral and computational analysis approaches
(TAYLOR & FRANCIS INC, 2019)The synthesis process, X-ray diffraction analysis of its single crystal form and the structural properties of the 4,4 '-oxydiphthalonitrile compound by Fourier transform infrared, nuclear magnetic resonance and ultraviolet-visible ... -
A Computation and Metering Method for Harmonic Emissions of Individual Consumers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)As the ratio of nonlinear loads fed from grids are increasing day by day, harmonic pollution problems seem to be more and more serious. Problems related to harmonics are the main sources of economic losses at power systems. ... -
Localization of Intracranial Lesions Using Superficial Stereotaxic Cranial Lesion Locator Based on Magnetic Resonance Images
(SAGE PUBLICATIONS INC, 2019)Background. Detection of a deep-seated lesion located in the brain parenchyma and major neuroanatomical sites is a critical issue in neurosurgery. Some neurosurgical cranial navigation systems have been developed that are ... -
Pupils' Opinions on an Educational Virtual Reality Game in Terms of Flow Experience
(KASSEL UNIV PRESS GMBH, 2019)The purpose of the study is; to evaluate a game developed by using virtual reality technology in the teaching of fractions which is one of the most difficult topics in the fourth-grade mathematics curriculum, according to ... -
The Perceptual Change of Reality in Tourist Places: Authenticity in Modern and Post-Modern Tourism Experiences
(KARE PUBL, 2019)The sustainability of cultural identity of society and cultural accumulation of space is possible by protecting them from the destructive effects of time and various external factors and by ensuring that they reach to the ... -
P-properties in Near-rings
(INST TEKNOLOGI BANDUNG, 2019)In this paper, assuming that N is a near-ring and P is an ideal of N, the P-center of N, the P-center of an element in N, the P-identities of N are defined. Their properties and relations are investigated. It is shown that ... -
ANALYTICAL EVALUATION OF HOLTSMARK DISTRIBUTION OF ENERGIES AND ITS ROLE IN PLASMA MICROFIELDS
(EDITURA BIBLIOTHECA-BIBLIOTHECA PUBL HOUSE, 2019)The distribution of electric microfields influences many elementary processes in plasma as well as governs a number of its optic properties. It is well known that the Holtsmark distribution was first used for plasma ... -
Some results for a certain class of holomorphic functions at the boundary of the unit disc
(AMER INST PHYSICS, 2019)We consider a version of the boundary Schwarz Lemma on a certain class which is denoted by K(alpha). For the function f (z) = z + c(2)z(2) + c(3)z(3) + ... defined in the unit disc E such that the function f (z) belongs ... -
