Extrinsic and intrinsic irreversibility in probabilistic dynamical laws
 In A. Khrennikov (Ed.), Quantum
, 2002
"... Two distinct conceptions for the relation between reversible, timereversal invariant laws of nature and the irreversible behavior of physical systems are outlined. The standard, extrinsic concept of irreversibility is based on the notion of an open system interacting with its environment. An altern ..."

The distribution of realized exchange rate volatility,
 Journal of the American Statistical Association
, 2001
"... Using highfrequency data on deutschemark and yen returns against the dollar, we construct modelfree estimates of daily exchange rate volatility and correlation that cover an entire decade. Our estimates, termed realized volatilities and correlations, are not only modelfree, but also approximatel ..."

. Noteworthy results include a simple normalityinducing volatility transformation, high contemporaneous correlation across volatilities, high correlation between correlation and volatilities, pronounced and persistent dynamics in volatilities and correlations, evidence of longmemory dynamics in volatilities
Estimating dynamic models of imperfect competition
, 2007
"... We describe a twostep algorithm for estimating dynamic games under the assumption that behavior is consistent with Markov perfect equilibrium. In the first step, the policy functions and the law of motion for the state variables are estimated. In the second step, the remaining structural parameters ..."

Amdahl’s law in the multicore era
 IEEE COMPUTER
, 2008
"... We apply Amdahl’s Law to multicore chips using symmetric cores, asymmetric cores, and dynamic techniques that allow cores to work together on sequential execution. To Amdahl’s simple software model, we add a simple hardware model based on fixed chip resources. Our results encourage multicore designe ..."

Collision detection and response for computer animation
 In Proc. of Intl. Conf. on Computer Graphics and Interactive Techniques
, 1988
"... When several objects are moved about by computer animarion, there is the chance that they will interpenetrate. This is often an undesired state, particularly if the animation is seeking to model a realistic world. Two issues are involved: detecting that a collision has occurred, and responding to it ..."

DYNAMICAL LAWS OF THE COUPLED GROSSPITAEVSKII EQUATIONS FOR SPIN1 BOSEEINSTEIN CONDENSATES ∗
"... Abstract. In this paper, we derive analytically the dynamical laws of the coupled GrossPitaevskii equations (CGPEs) without/with an angular momentum rotation term and an external magnetic field for modelling nonrotating/rotating spin1 BoseEintein condensates. We prove the conservation of the angu ..."

Deformation constraints in a massspring model to describe rigid cloth behavior
 IN GRAPHICS INTERFACE
, 1995
"... This paper describes a physicallybased model for animating cloth objects, derived from elastically deformable models, and improved in order to take into account the nonelastic properties of woven fabrics. A cloth object is first approximated to a deformable surface composed of a network of masses ..."

Random Graph Dynamics
, 2007
"... Chapter 1 will explain what this book is about. Here I will explain why I chose to write the book, how it is written, where and when the work was done, and who helped. Why. It would make a good story if I was inspired to write this book by an image of Paul Erdös magically appearing on a cheese ques ..."

Hyperbolic Conservation Laws with Stiff Relaxation Terms and Entropy
 Comm. Pure Appl. Math
, 1992
"... We study the limiting behavior of systems of hyperbolic conservation laws with stiff relaxation terms. Reduced systems, inviscid and viscous local conservation laws, and weakly nonlinear limits are derived through asymptotic expansions. An entropy condition is introduced for N \Theta N systems that ..."
