Hidden Conformal Symmetry of Extremal Kerr-Bolt Spacetimes
Hidden Conformal Symmetry Extremal Kerr-Bolt Spacetimes
2010/12/23
We show that extremal Kerr-Bolt spacetimes have a hidden conformal symmetry. In this regard, we consider the wave equation of a massless scalar field propagating in extremal Kerr-Bolt spacetimes and ...
Use of a submodel method to check the bolt strength of marine equipment
submodel method gear case connection component shock-resistance
2011/9/13
A submodel method was proposed that works from computational models of marine gear cases to verify that the proposed bolts will give it sufficient structural integrity. Calculations for marine equipme...
