A New Principle to Determine the Variational Parameter for the Variational–Cumulant Expansion

Communications in Theoretical Physics, 1999
The key point of the variational-cumulant expansion is the determination of the variational parameter. In this paper, we present the improved mean-field hypothesis (IMFH) which is the base to determine the parameter. The new method derived from the IMFH shows advantage over previous methods. The critical temperature and some thermal dynamical functions

A new power MOSFET model including the variation of parameters with the temperature

Proceedings of the 1998 Second IEEE International Caracas Conference on Devices, Circuits and Systems. ICCDCS 98. On the 70th Anniversary of the MOSFET and 50th of the BJT. (Cat. No.98TH8350), 2002
A new PSpice model of power MOSFETs has been recently developed aiming to account for the parameter variations with temperature. The present paper discusses the new model in detail and reports static and dynamic validation tests at different working temperatures in the range 25-150/spl deg/C on actual devices.

New Method to Calculate the Time Variation of the Force Field Parameter

Journal of Geophysical Research: Space Physics, 2018
AbstractGalactic cosmic rays (CRs) entering the heliosphere are affected by interplanetary magnetic fields and solar wind disturbances resulting in the modulation of the CR total flux observed in the inner heliosphere. The so‐called force field model is often used to compute the galactic CR spectrum modulated by the solar activity due to the fact that ...

Parameter Variation Tolerance and Error Resiliency: New Design Paradigm for the Nanoscale Era

Proceedings of the IEEE, 2010
Variations in process parameters affect the operation of integrated circuits (ICs) and pose a significant threat to the continued scaling of transistor dimensions. Such parameter variations, however, tend to affect logic and memory circuits in different ways.

A new robust SPMSM control to parameter variations in flux weakening region

Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 1996
A new implementation strategy for the flux weakening control of a surface mounted permanent magnet synchronous motor (SPMSM) is proposed. It is implemented based on the output of the synchronous PI current regulator-reference voltage to PWM inverter.

New applications of mu to real-parameter variation problems

1985 24th IEEE Conference on Decision and Control, 1985
The structured singular value (SSV) has been used in recent studies of the robust stability of feedback systems subject to real-parameter variations. In this paper, we summarize the results obtained when some new upper-bounds on the SSV for real-parameters (reference [1]) were used in two studies of flight control systems.

Lens Area Variations in Impact Resistance—A New Parameter of Eye‐Protective Lenses

Clinical and Experimental Optometry, 1975
Experiments are described which demonstrate very large and hitherto unknown variations in the impact resistance of thermally toughened glass lenses, at different lens areas and with different angles of impact. The findings are discussed.

New Discretization Methodology for Three-Dimensional Mechanical Parameters Considering Spatial Variations

International Journal of Applied Mechanics, 2019
In this paper, the uncertain mechanical parameters are modeled as spatial random fields (RFs). A new tetrahedral discretization methodology of three-dimensional (3D) RF is proposed based on the local average (LA) theory. An analytical formula and a numerical formula of the covariance for any two tetrahedral RF elements are developed. Its main advantage,
