The effect of glycerol on signal supression during electrospray ionization analysis of proteins
(2004-06-04)
The effect of salts, detergents and chaotropic agents on mass spectrometric analysis are relatively well understood, mainly due to their actions decreasing the performance of ESI interface in mass spectrometric analysis. ...
On Nonlinear Dynamics and Control of A Particular Portal Frame Foundation Model, Excited by a Non-Ideal Motor
(2003-12-08)
The nonlinear dynamic response and a nonlinear control method of a particular portal frame foundation for an unbalanced rotating machine with limited power (non-ideal motor) are examined. Numerical simulations are performed ...
A low-voltage programmable-gain CMOS amplifier with very-low temperature-drift
(2001-01-01)
A new topology for a LVLP variable-gain CMOS amplifier is presented. Input- and load-stage are built around triode-transconductors so that voltage-gain is fully defined by a linear relationship involving only device-geometries ...
Electrical Modelling and Power Quality Analysis of Three-Phase Induction Furnace
(Ieee, 2014-01-01)
The induction furnaces are loads having high power and nonlinear characteristic. The power consumption depends on the stage of melting metal in its interior and can cause serious problems on the electric power distribution ...
A structure excited by a DC motor of limited power supply and controlled by a pendulum like device
(2008-06-17)
In this paper, a mathematical model is derived via Lagrange's Equation for a shear building structure that acts as a foundation of a non-ideal direct current electric motor, controlled by a mass loose inside a circular ...

PHB/PZT composite
(2005-12-01)
Flexible standing films of piezoelectric composite made of lead zirconate titanate (PZT) ceramic powder and Poly(3-hydroxybutyrate) (PHB) in powder form were obtained by mixing both polymers mechanically and pressed at ...
Computation of Surge Voltage in Transmission Tower Located above Frequency-Dependent Soil
(2021-01-01)
The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...
Alternative Methods to Calculate Electromagnetic Transients in Grounding Systems
(2019-09-01)
Grounding electrodes are essential in electrical power system to maintain a reliable operation, and to guarantee the safety of personnel and equipment. When a lightning strikes at a transmission tower, surge current waves ...
High tech garbage can help engineering colleges to improve hands-on education
(2011-12-01)
This paper presents a discussion on the potential use of high tech garbage, including electronic waste (e-waste), as a source of mechanisms, sensors and actuators, that can be adapted to improve the reality of microprocessor ...
