Moving breathers in bent DNA with realistic parameters
(2004-10-30)
Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen ...

A Direct Extension of the Avrami Equation to Describe the Non-isothermal Crystallization of Al-base Alloys
(Elsevier, 2007)
A direct extension of the Avrami equation considering the temperature dependence of the frequency factor is applied to describe the crystallization of a series of Al-Mm-Ni-Co amorphous alloys (Mm is a mischmetal). For high ...

Nonlinear H_infinity control with PID structure for robot manipualtors
(Elsevier, 2002)
In this paper the nonlinear H∞ control for robot manipulators introduced in (Feng, W., Postlethwaite, I., 1994) is extended. An additional integral term is included to cope with persistent disturbances, such as constant ...

A new controller for the inverted pendulum on a cart
(2008)
This paper presents a complete solution to the problem of swinging-up and stabilization of the inverted pendulum on a cart, with a single control law. The resulting law has two parts: first, an energy-shaping law is able ...

Estimates for singular multiplicative character sums
(Duke University Press, 2005)
We give some estimates for multiplicative character sums on quasiprojective varieties over finite fields depending on the severity of the singularities of the variety at infinity. We also remove the hypothesis of ...

Specific Heat Measurements on Amorphous and Nanocrystalline Al88Y5Ni5Co2
(Elsevier, 2009)
Specific heat at constant pressure, CP, was measured on amorphous and nanocrystalline Al88Y5Ni5Co2 alloys from differential scanning calorimetry experiments. Linear behavior of CP versus temperature from 323 to 423 K is ...

Crystallization behavior and magnetic properties of Cu-containing Fe- Cr- Mo- Ga- P- C- B alloys
(2006)
Multicomponent Fe65.5Cr4Mo4Ga4P12C5B5.5 amorphous alloy is known to have good soft magnetic properties combined with large glass-forming ability. Searching for a nanocrystalline structure that could improve its magnetic ...
