a study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Transverse force on a quantized vortex in a superfluid.
We have derived an exact expression for the total nondissipative transverse force acting on a quantized vortex moving in a uniform background. The derivation is valid for neutral boson or fermion superfluids, provided the order parameter is a complex scalar quantity. This force is determined by the oneparticle density matrix far away from the vortex core, and is found to be the Magnus force pro...
متن کاملLongitudinal-Torsional and Two Plane Transverse Vibrations of a Composite Timoshenko Rotor
In this paper, two kinds of vibrations are considered for a composite Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic and potential energies and virtual work due to the gyroscopic effects are calculated and the set of six governing equations and boundary conditions are derived using Hamilton principle. Differential quadrature method (DQM) is used as ...
متن کاملLongitudinal vortex structures in a cylinder wake
Recently, flow visualizations by Wei and Smith,’ Williamson,’ Welsh et a1.,3 and Bays-Muchmore and Ahmed4 have shown that three-dimensional (3-D) vertical structures develop in the wake of a bluff body. The 3-D vertical structures were found to include pairs of counterrotating longitudinal vortices superimposed on the nominally two-dimensional (2-D) Kirmin vortex street as speculated by Grant’ ...
متن کاملLongitudinal and Transverse Nuclear Shadowing
Nuclear shadowing arises from multiple scattering of the hadronic fluctuations (|qq̄〉, |qq̄g...〉) of the virtual photon in a nucleus. We predict different longitudinal and transverse shadowing and an A–dependence of R ≡ σL/σT which can be up to a 50% effect. The possibility of detecting nuclear effects on R at HERA is discussed. To be published in the Proceedings of the Workshop on “Future Physic...
