Crossing minimization in weighted bipartite graphs
(Springer, 2007)Given a bipartite graph G = (L-0, L-1, E) and a fixed ordering of the nodes in L-0, the problem of finding an ordering of the nodes in L-1 that minimizes the number of crossings has received much attention in literature. ... -
Crossing minimization in weighted bipartite graphs
(Elsevier B.V., 2009-12)Given a bipartite graph G = (L0, L1, E) and a fixed ordering of the nodes in L0, the problem of finding an ordering of the nodes in L1 that minimizes the number of crossings has received much attention in literature. The ... -
Cryptanalysis of a chaos-based image encryption algorithm
(Elsevier Science BV, 2009-03-30)A chaos-based image encryption algorithm was proposed in [Z.-H. Guan, F. Huang, W. Guan, Phys. Lett. A 346 (2005) 153]. In this Letter, we analyze the security weaknesses of the proposal. By applying chosen-plaintext and ... -
Cryptanalysis of a cryptosystem based on discretized two-dimensional chaotic maps
(Elsevier Science BV, 2008-11-17)Recently, an encryption algorithm based on two-dimensional discretized chaotic maps was proposed [Xiang et al., Phys. Lett. A 364 (2007) 252]. In this Letter, we analyze the security weaknesses of the proposal. Using the ... -
Cryptanalysis of a multi-chaotic systems based image cryptosystem
(Elsevier Science BV, 2010-01-15)This paper is a cryptanalysis of a recently proposed multi-chaotic systems based image cryptosystem. The cryptosystem is composed of two shuffling stages parameterized by chaotically generated sequences. We propose and ... -
Cryptanalysis of a new substitution-diffusion based image cipher
(Elsevier Science BV, 2010-07)This paper introduces two different types of attacks on a recently proposed cryptosystem based on chaotic standard and logistic maps. In the two attacks, only a pair of (plaintext/ciphertext) was needed to totally break ... -
Cryptanalysis of Fridrich's chaotic image encryption
(World Scientific Publishing, 2010-05)We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ... -
Cryptanalysis of image encryption with compound chaotic sequence
(IEEE, 2009)Recently, an image encryption algorithm based on compound chaotic sequence was proposed [Tong et al., Image and Vision Computing 26 (2008) 843]. In this paper, we analyze the security weaknesses of the proposal. We give ... -

(Greenleaf Publishing, 2015-07)This study examines the private companies that publish CSR reports in Turkey. Turkey has a growing economy, located in an international arena with an increasing number of global brands starting to export their products ... -
Cubic (1, 2)-ideals on semigroups
(Işık University Press, 2022)In this paper we introduce the concept of cubic (1, 2)-ideals on semigroups and we study basic properties of cubic (1, 2)-ideals. In particular, we find condition cubic bi-ideal is cubic (1, 2)-ideal coincide. Finally we ... -
Cubic B-spline collocation method for coupled system of ordinary differential equations with various boundary conditions
(Işık University Press, 2022)This paper is concerned with collocation approach using cubic B-spline to solve coupled system of boundary value problems with various boundary conditions. The collocation equations are methodically derived using cubic B ... -
Cubic pythagorean fuzzy linear spaces
(Işık University Press, 2023-07)Pythagorean fuzzy sets assist in handling more uncertain and vague data than fuzzy sets and intuitionistic fuzzy sets. The notion of cubic pythagorean fuzzy sets is defined by combining interval valued pythagorean fuzzy ... -
Culture and silviculture: origins and evolution of silviculture in Southeast Europe
(Commonwealth Forestry Assoc, 2018-03)Silvicultural practices are generally developed to meet societal objectives given the constraints of the site. This simple premise is a foundation of modern silviculture. However, silviculture may vary for other reasons ... -
