Speeding up simulations of relativistic systems using an optimal boosted frame
, 2009 It can be computationally advantageous to perform computer simulations in a Lorentz boosted frame for a certain class of systems. However, even if the computer model relies on a covariant set of equations, it has been pointed out that algorithmic ...

, 2004 Electronic structure calculations, using the charge and spin self-consistent Korringa- Kohn-Rostoker (KKR) method, have been performed for several $R$Mn$X$ compounds ($R$ = Mg, Ca, Sr, Ba, Y; $X$ = Si, Ge) of the CeFeSi-type structure.

Non-equilibrium condensation and coarsening of field-driven dipolar colloids
, 2012 In colloidal suspensions, self-organization processes can be easily fueled by external fields. One particularly interesting class of phenomena occurs in monolayers of dipolar particles that are driven by rotating external fields.

Voluntary Approaches to Food Safety : A Unified Framework [PDF]
The emergence and the multiplication of safety quality management system within the food supply chain were extensively analyzed in the food safety literature. Some papers deal more specifically with the voluntary implementation by firms of these systems (

First-Order Type Effects in YBa$_2$Cu$_3$O$_{6+x}$ at the Onset of Superconductivity
, 2008 We present results of Raman scattering experiments on tetragonal ${\rm (Y_{1-y}Ca_{y})Ba_{2}Cu_{3}O_{6+x}}$ for doping levels $p(x,y)$ between 0 and 0.07 holes/CuO$_2$.

Input current shaped ac-to-dc converters [PDF]
Input current shaping techniques for ac-to-dc converters were investigated. Input frequencies much higher than normal, up to 20 kHz were emphasized. Several methods of shaping the input current waveform in ac-to-dc converters were reviewed.

A Secular Relativistic Model For Solar System's Numerical Simulations [PDF]
, 2010 Using Gauss' averaged equations, we compute the secular relativistic effects generated by the Sun on the argument of the perihelion and the mean anomaly of an orbit.

Offshoring and Specialisation: Are Industries Moving Abroad? [PDF]
This paper investigates the impact of off-shoring on specialisation via its effect on national endowments and productivity. We use different definition of off-shoring to properly capture international fragmentation of production, while controlling for ...

This paper look at why most migration flows include observable jumps, a phenomenon that is in line with migration irreversibility. We have presented a real option model where the migration choice depends on both the wage differential between the host ...
