The reduced Hessian SQP algorithm presented in is developed in this paper into a practical method for large scale optimization The novelty of the algorithm lies in the incorporation of a correction vector that approximates the cross term ZWY pY This improves the stability and robustness of the algorithm without increasing its computational cost The paper studies how to implement the algorithm e...

This paper studies the pricing of intensity-based defaultable bonds where the volatility of default intensity is assumed to be random and driven by two different factors varying on fast and slow time scales. Corrections to the constant intensity of default are obtained and then how these corrections influence the term structure of interest rate derivatives is shown. The results indicate that th...

An accelerating flat universe with a variable cosmological term is obtained in the Robertson-Walker metric. The variable cosmological term is defined by the correction terms of the metric tensor field. Simple solutions of the scale factor and the cosmological term are shown. In this model of the universe, the magnitude-redshift relation is analytically studied to see if the model reproduces the...

Objectives: The aims of this study were to evaluate the efficacy of conservative treatment in patients with and without cervical ribs and Thoracic Outlet Syndrome (TOS). From so many kinds of conservative treatment in literature, we used a multidisciplinary approach (correction of posture, maximizing muscle endurance and power, stretch shorten muscles, massage for trigger points and maximize th...

A large eddy simulation (LES) a posteriori study is conducted for a temporal mixing layer which initially contains different species in the lower and upper streams and in which the initial pressure is larger than the critical pressure of either species. A vorticity perturbation, initially imposed, promotes roll-up and a double pairing of four initial spanwise vortices to reach a transitional st...

Decomposition methods have been proposed in the past to approximate solutions to large sequential decision making problems. In contexts where an agent interacts with multiple entities, utility decomposition can be used where each individual entity is considered independently. The individual utility functions are then combined in real time to solve the global problem. Although these techniques c...

In this letter we study a new class of inflation models which generalize the Dirac-Born-Infeld (DBI) action with the addition of a nonminimal kinetic coupling (NKC) term. We dubbed this model as the new DBI inflation model. The NKC term does not bring new dynamical degree of freedom, so the equations of motion remain of second order. However, with such a coupling, the action is no longer linear...

The formulation of the extended Kalman lter for a multilayer nonlinear quasi-geostrophic ocean circulation model is discussed. The nonlinearity in the ocean model leads to an approxima-tive equation for error covariance propagation, where the transition matrix is dependent on the state trajectory. This nonlinearity complicates the dynamics of the error covariance propagation, and eeects which a...
