    • On positive operators without invariant sublattices 

      Çağlar, Mert; Gönülli, Uğur; Mısırlıoğlu, Remzi Tunç (2009)
      By slightly modifying some of the examples given in [6], we obtain further examples of positive operators on the discrete Banach lattices c0, c, and `p (1 ≤ p < ∞) without non-trivial closed invariant sublattices.
    • On Q-Euclidean L-fuzzy Ideals of Rings 

      Koç, Ayten; Balkanay, Erol (TÜBİTAK, 2004)
      In this paper we define a θ-Euclidean level subset and a θ-Euclidean level ideal. We also give some properties of a θ-Euclidean level subset.

      We prove a growth theorem for a function to belong to the class Sigma(mu; a) and generalize a Weierstrass-Enneper representation type theorem for the minimal surfaces given in [5] to spacelike minimal surfaces which lie ...
    • On Scheduling Project Activities With Variable Expenditure Rates 

      Commercial projects are undertaken with the expectation of maximizing financial returns. There are a variety of cash flow models in the literature in which payments, whose amounts depend on the type of contract quoted ...
    • On Short-Term Periodicity Of The Solar Radius Measurements

      The aim of the present study is to investigate the short-term periodicity in the solar radius measurements and to compare with the short periods in sunspot numbers, sunspot areas and flare index data. The spectral analysis ...
    • On some alpha-convex functions 

      Owa, Shigeyoshi; Polatoğlu, Yaşar; Yavuz, Emel; Acu, Mugur; Al-Oboudi, Fatima; Darus, Maslina (2008-06)
      In this paper, we define a general class of α-convex functions, denoted by MLβ,α(q), with respect to a convex domain D (q(z) ∈ Hu(U), q(0) = 1 , q(U) = D) contained in the right half plane by using the linear operator ...
    • On some first-order differential subordination 

      Yavuz, Emel; Nunokawa, M.; Sokół, J.; Cho, N.E.; Owa, S. (2014-07)
      Let denote the class of functions f that are analytic in the unit disc and normalized by f(0) = f′(0) − 1 = 0. In this paper, we investigate the class of functions such that in . We determine conditions for α and β under ...

    • On the calculation of group characters 

      Karadayı, Hasan Rıfat; Güngörmez, Mustafa (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2007-12)
      It is known that characters of irreducible representations of finite Lie algebras can be obtained using the Weyl character formula including Weyl group summations which make actual calculations almost impossible except for ...
    • On the class of harmonic mappings which is related to the class of bounded boundary rotation 

      Polatoğlu, Yaşar; Aydoğan, Melike; Kahramaner, Yasemin (Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 Usa, 2015-09-15)
      The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ...
    • On the Direction Guidance in Structure Tensor Total Variation Based Denoising 

      Demircan-Tureyen, Ezgi (2019-07)
      This paper introduces a new analysis-based regularizer, which incor­ porates the neighborhood-awareness of the structure tensor total variation (STV) and the tunability of the directional total variation (DTV), in favor ...
    • On the effectiveness of virtual reality in the education of software engineering 

      Akbulut, Akhan; Çatal, Çağatay; Yıldız, Burak (Wiley, 111 River St, Hoboken 07030-5774, NJ USA, 2018-07)
      The popularity of virtual reality headsets have been rapidly increasing. With this technology, students can efficiently interact with the course content and learn the material faster than the traditional methodologies. In ...

      We show that the period clustering of anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), their X-ray luminosities, ages, and statistics can be explained with fall back disks with large initial specific ...

      Nunokawa, M.; Owa, Shigeyoshi; Cho, N. E.; Sokół, J.; Yavuz Duman, Emel (Springer International Publishing, 2013-12)
      We estimate |Arg{p(z)}| for functions of the form p(z)=1+a1z+a2z2+a3z3+⋯ in the unit disc D={z:|z|<1} under several assumptions. By using Nunokawa’s lemma, we improve a few of Mocanu’s results obtained by differential ...
