Electrical Impedance Spectroscopic Studies On Bread Staling : Sensors And Instrumentation
(2013-04-15)
Quality control is essential in food industry and efficient quality assurance is becoming increasingly important. The assessment of food quality still centers on its sensory properties (appearance, aroma and texture). Bread ...
"Optical Diffraction By Micro Cylinder" - A Few Investigations
(2013-04-04)
Micro-cylinders with the diameters spanning the 1-20 μm range are growing in importance, for realizing devices with new functionalities. For custom functionalities, their device-designs impose, tolerance-related constraints ...
Novel Methods To Interrogate Fiber Bragg Grating Sensors
(2013-02-14)
A novel detection technique to estimate the amount of chirp in fiber Bragg gratings (FBGs) is proposed. This method is based on the fact that reflectivity at central wavelength of FBG reflection changes with strain/temperature ...
Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(2013-02-13)
In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ...
Escape Of High Mass Ions Due To Initial Thermal Energy And Its Implications For RF Trap Design
(2013-05-31)
This thesis investigates the loss of high mass ions due to the initial thermal energy in ion trap mass analyzers. It provides an analytical expression for estimating the percentage loss of ions of a given mass at a particular ...
Axially Symmetric Equivalents Of Three-Dimensional Rf Ion Traps
(2013-09-13)
This thesis presents axially symmetric equivalents of three-dimensional rf ion traps. Miniaturization in mass spectrometry has focused on miniaturizing mass analyzers. Decrease in mass analyzer size facilitates reduction ...
A Preliminary Investigation Of The Role Of Magnetic Fields In Axially Symmetric rf Ion Traps
(2013-07-16)
Axially symmetric rf ion traps consists of a mass analyser having three electrodes, one of which is a central ring electrode and the other two are endcap electrodes. In the ideal Paul trap mass spectrometer, the electrodes ...
