A Method To Evade Keyword Based Censorship
(Computer Science & Engineering, 2014-12)
Many countries block the content of web pages which are deemed against the morals, religious rules or policies set by government or organization. Countries like China block the post which is against their government interest. ...
Colloidal quantum dot absorption enhancement in flexible Fano filters
(IEEE, 2010-02-25)
We report here modified absorption property of colloidal quantum dots CQDs inside flexible Fano
filters—made of patterned single crystalline silicon nanomembrane transferred onto flexible plastic
substrates. Enhanced ...
Encapsulation for efficient electrical injection of photonic crystal defect mode surface-emitting lasers
(IEEE, 2006-01-31)
We propose and report an encapsulated photonic crystal concept for efficient electrical injection of
photonic crystal surface-emitting lasers. Detailed rate equation analysis reveals a significant
threshold current ...
Resonance control of membrane reflectors with effective index engineering
(IEEE, 2009-07-14)
We report here broadband membrane reflectors based on Fano resonances in patterned silicon
nanomembranes. Resonance control of the reflectors was realized either by partially removing
buried oxide layer underneath the ...
Fano filters based on transferred silicon nanomembranes on plastic substrates
(IEEE, 2008-08-13)
We report here the characteristics of surface-normal optical filters based on Fano resonances on
patterned single crystalline silicon nanomembranes SiNMs , which were fabricated and transferred
onto transparent plastic ...
Capacity and coverage management issues in the forward link of CDMA systems
(IEEE, 2003-04)
A multisensory approach is being developed at the University of Texas at Arlington (UTA) to improve upon current capabilities in environmental monitoring. These sensors consist of an FT-IR for operation in the near to ...
Branch-and-Bound for Model Selection and its Computational Complexity
(IEEE Xplore, 2010-09-02)
Branch-and-bound methods are used in various data analysis problems such as clustering, seriation
and feature selection. Classical approaches of branch-and-bound based clustering search through combinations
of various ...
Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles
(American Institute of Physics, 2007-08-30)
FePt nanoparticles with a size of 3 nm and thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles were prepared by chemical synthesis and a salt-matrix annealing technique. ...
High thermal stability of carbon-coated L1[subscript]0-FePt nanoparticles prepared by salt-matrix annealing
(Institute of Applied Physics, 2008-02-08)
Monodisperse L10-FePt nanoparticles with size ranging from 3 to 8 nm were prepared by the salt-matrix annealing method. It was observed that the annealed particles have high thermal stability—no sintering occurred even ...
Curie temperatures of annealed FePt nanoparticle systems
(American Institute of Physics, 2007-03-28)
The chemically synthesized FexPt100-x nanoparticles with controlled compositions were annealed to transfer the disordered face-centered-cubic structure to the ordered structure. It was found that the L10 FePt structure can ...
