The Bit formation using atomic force microscopy (AFM) was studied on 270-nm-thick < 111 > preferentially oriented Pb(Zr0.4Ti0.6)O-3 (PZT) films prepared by the sol-gel process. To minimize the cantilever-sample capacitive farce interaction, the experiment ...
This work deals with modeling and control of thermoacoustic combustion instabilities in lean premixed combustion systems. Because of the complex interactions present in thermoacoustic systems, a network modeling approach is used. The model of each network ...
The electrochem. promotion of RuO2 catalysts interfaced with yttria stabilized zirconia was studied for the combustion of ethylene. The complete oxidn. of ethylene can be described by an Eley-Rideal type mechanism. In situ work function measurements were u ...
The charge transport in nanoporous ZnO was studied by laser flash induced photocurrent transients. The results are discussed using a diffusion model and compared with previous results on TiO2. The charge transport was highly dependent on the potential givi ...
Using a first-principles approach, we assign N 1s core-level shifts at ammonium exposed Si(001)2x1 surfaces to definite bonding configurations of N atoms. Model structures are obtained by fully relaxing the atomic positions of N atoms in different bonding ...
We model Si 2p core-level shifts at Si-(ZrO2)(x)(SiO2)(1-x) interfaces for varying Zr content x. Using a first-principles approach, we calculate Si 2p shifts for a model interface and for cluster models, and establish the validity of a linear dependence of ...
We formulate the tomographic reconstruction problem in a variational setting. The object to be reconstructed is considered as a continuous density function, unlike in the pixel-based approaches. The measurements are modeled as linear operators (Radon trans ...
Reasons for the continuing difficulty in making definitive measurements of pulse wave attenuation in elastic tubes and arteries in the presence of reflections are sought. The measurement techniques available were re-examined in elastic tubes mimicking the ...
Change detection generally is the difference between images. The differences or changes could be due to moving objects or a variation of illumination. In general the goal is to extract only changes due to moving object that occur int eh scene, and to ignor ...
LTCC (Low-Temperature Cofired Ceramic) has attracted considerable interest as a material for sensors and microfluidic circuits, for which dimensional accuracy is essential. The irregular shrinkage behaviour of LTCC tapes must be taken into account when des ...
