Ball and Burmester points in Lorentzian sphere kinematics

Abdullah Inalcik; Ersoy, Soley (ACADEMIC PUBLICATION COUNCIL, 2015)

In this work, we study Lorentzian spherical motion of rigid bodies by using instantaneous invariants and define Lorentzian inflection curve, Lorentzian circling points curve and Lorentzian cubic of twice stationary curve, ...
Data Descriptor: A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins

Tunca, Hatice (NATURE PUBLISHING GROUP, 2018)

Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ...
Energy Decay and Continuous Dependence for Damped Semilinear Wave Equation

Sevket Guer; Gür, Şevket; Metin Yaman (SPRINGER INTERNATIONAL PUBLISHING AG, 2019)

We study uniform stabilization and the continuous dependence of solutions to an initial and boundary value problem for a nonlinear hyperbolic equation with (possibly strong) linear damping.
Energy Levels and Electric Dipole Transitions for Neutral Actinium (Z=89)

Ürer, Güldem; Özdemir, Leyla (SPRINGER HEIDELBERG, 2012)

We have reported a relativistic multiconfiguration Dirac-Fock calculation including Breit and quantum electrodynamic contributions on the level structure of atomic actinium, Ac I (Z = 89). The computations have been carried ...
Estimation of the Most Probable Muon Energy at Sea Level Using Two-Paddle Cosmic Ray Detectors
