Electromagnetic Waves in a Rotating Frame of Reference

We discuss the electromagnetic measurements of rotating observers and study the propagation of electromagnetic waves in a uniformly rotating frame of reference. The phenomenon of helicity-rotation coupling is elucidated and some of the observational consequences of the coupling of the spin of a particle with the rotation of a gravitational source are briefly examined.

Three comments on the anti-frame rule

It is well-known that a careless combination of parametric polymorphism and weak references is unsound. (A weak reference is one that can be read and written without restrictions, as in ML.) The standard way to work around this problem is to rely on the value restriction [7] that is, to restrict the ∀-introduction rule to values (as opposed to arbitrary terms). Charguéraud and Pottier [3] point...

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...

Constructing a Body-Fixed Reference Frame for a Polyatomic Molecule

An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
