Incorporating Convexity in Bond Portfolio Immunization Using Multifactor Model: A Semidefinite Programming Approach
Bond portfolio immunization is a classical issue in finance. Since Macaulay gave the concept of duration in 1938, many scholars proposed different kinds of duration immunization models. In the literature of bo...

First-Order Algorithms for Convex Optimization with Nonseparable Objective and Coupled Constraints
In this paper, we consider a block-structured convex optimization model, where in the objective the block variables are nonseparable and they are further linearly coupled in the constraint. For the 2-block cas...

Harmonic balance method with alternating frequency/time domain technique for nonlinear dynamical system with fractional exponential
Comparisons of the common methods for obtaining the periodic responses show that the harmonic balance method with alternating frequency/time (HB-AFT) domain technique has some advantages in dealing with nonlin...

Bifurcation on synchronous full annular rub of rigid-rotor elastic-support system
An aero-engine rotor system is simplified as an unsymmetrical-rigid-rotor with nonlinear-elastic-support based on its characteristics. Governing equations of the rubbing system, obtained from the Lagrange equa...

Powell’s optimal identification of material constants of thin-walled box girders based on Fibonacci series search method
A dynamic Bayesian error function of material constants of the structure is developed for thin-walled curve box girders. Combined with the automatic search scheme with an optimal step length for the one-dimens...

Fast Swee** Fifth Order WENO Scheme for Static Hamilton-Jacobi Equations with Accurate Boundary Treatment
A fifth order weighted essentially non-oscillatory (WENO) fast swee** method is designed in this paper, extending the result of the third order WENO fast swee** method in J. Sci. Comput. 29, 25–56 (2006) and ...

Thrust generation and wake structure of wiggling hydrofoil
Marine animals and micro-machines often use wiggling motion to generate thrust. The wiggling motion can be modeled by a progressive wave where its wavelength describes the flexibility of wiggling animals. In t...

Dynamic Bayesian estimation of displacement parameters of continuous curve box based on Novozhilov theory
The finite strip controlling equation of pinned curve box was deduced on basis of Novozhilov theory and with flexibility method, and the problem of continuous curve box was resolved. Dynamic Bayesian error fun...

On the existence and uniqueness of solutions for a class of variational inequalities with applications to the signorini problem in mechanics
In this paper, we introduce a new unified and general class of variational inequalities, and show some existence and uniqueness results of solutions for this kind of variational inequalities. As an application.....
