2D quasi-planar or 3D structures? A comparison between CrBn (n=2-10) wheel-like clusters and their corresponding 3D pyramidal clusters, and their hydrogen storage capability
(World Scientific Publ Co Pte Ltd, 2015)In this study, we investigated stable structures for a transition metal atom-boron (CrB) wheel-like clusters and compared them with their corresponding 3D counterparts by means of density functional theory (DFT). In addition, ... -
Computational investigations of mechanic, electronic and lattice dynamic properties of yttrium based compounds
(World Scientific Publ Co Pte Ltd, 2018)Electronic, mechanic and lattice dynamic properties of yttrium-based compounds, X3Y, where X = Pd, Pt and Rh were investigated using the density functional theory. The electronic band calculations demonstrated that X3Y ... -
A curious matrix-sum identity and certain finite sums identities
(World Scientific Publ Co Pte Ltd, 2015)In this paper, we consider two generalized binary sequences and then give a generalization of a matrix equality proposed as an advanced problem. Then, we derive new certain finite sums including the generalized binary ... -
The derivative and tangent operators of a motion in Lorentzian space
(World Scientific Publ Co Pte Ltd, 2017)In this paper, by using Lorentzian matrix multiplication, L-Tangent operator is obtained in Lorentzian space. The L-Tangent operators related with planar, spherical and spatial motion are computed via special matrix groups. ... -
Electronic structure and magnetic properties of PbMO3 (M = Fe, Co, Ni) magnetic perovskites: An ab initio study
(World Scientific Publ Co Pte Ltd, 2014)We present the electronic, magnetic and structural properties of the magnetic transition metal oxides PbMO3 (M= Fe, Co, Ni) in cubic perovskite structure. The calculations are based on the density functional theory (DFT) ... -
General helices with spacelike slope axis in Minkowski 3-space
(World Scientific Publ Co Pte Ltd, 2019)In the present paper, we consider general helix with spacelike slope axis for all possible types of curves in Minkowski 3-space. We give the conditions under which the curves in Minkowski 3-space have spacelike slope axis. ... -
Lorentzian stationary surfaces and bi-null curves in R-2(5)
(World Scientific Publ Co Pte Ltd, 2017)In this paper, we study Lorentzian stationary surfaces related to bi-null curves in R-2(5). Considering a Gauss-like map, we get Lorentzian stationary surfaces and marginally trapped surfaces in the pseudo-sphere S-2(4) (1). -
A new approach to design the ruled surface
(World Scientific Publ Co Pte Ltd, 2019)This paper considers a kind of design of a ruled surface. The design interconnects some concepts from the fields of computer-aided geometric design (CAGD) and kinematics. Dual unit spherical Bezier-like curves on the dual ... -
New calculation for some ground state features of 40ca, 48ca 32s and 39k nuclei
(World Scientific Publ Co Pte Ltd, 2010)Some ground states features of S-32, K-39, Ca-40 and Ca-48 nuclei are investigated using the Hartree-Fock method with the Skyrme SKM* and SLy4 forces calculated in two different code implementations. The calculated total ... -
Odd nuclei and shape phase transitions: the role of the unpaired fermion
(World Scientific Publ Co Pte Ltd, 2011)Shape phase transitions in even and odd systems are reviewed within the frameworks of the Interacting Boson Model(IBM) and the Interacting Boson Fermion Model(IBFM), respectively and compared with geometric models when ... -
On Bishop frame of a null Cartan curve in Minkowski space-time
(World Scientific Publ Co Pte Ltd, 2018)In this paper, we define the Bishop frame of a null Cartan curve in Minkowski space-time E-1(4). We obtain the Bishop's frame equations of a null Cartan curve which lies in the timelike hyperplane of E-1(4). We show that ... -
