Metastable Intermediate in LixMnO₂ Layered to Spinel Phase Transition
(2002-01)Ab Initio calculations suggest that partially lithiated layered LixMnO₂ transforms to spinel in a two-stage process. In the first stage, a significant fraction of the Mn and Li ions rapidly occupy tetrahedral sites, forming ... -
Methods for Calculating the Optical Band Structure of Photonic Composites
(2002-01)Lately, there has been an increasing interest in studying the propagation of electromagnetic waves in periodic dielectric structures (photonic crystals). Like the electron propagation in semiconductors, these structures ... -
Micro Injection-Molding of Cyclic Olefin Copolymer Using Metallic Glass Insert
(2007-01)There is shift in trend towards the use of high quality polymers as the base material in manufacturing microfluidic chips. In this paper, an amorphous metallic alloy mold insert was used in a micro injection-molding process ... -
Micro Raman Spectroscopy of Annealed Erbium Implanted GaN
(2004-01)Wurtzite GaN epilayers grown by metal organic chemical vapor deposition on sapphire substrates were subsequently ion implanted with Er to a dose of 5×10¹⁵ cm⁻². The implanted samples were annealed in nitrogen atmosphere ... -
Micro-layered-photolithography for Micro-Fabrication and Micro-Molding
(2005-01)A novel process based on the principle of layered photolithography has been proposed and tested for making real three-dimensional micro-structures. An experimental setup was designed and built for doing experiments on this ... -
Micro-porous Paclitaxel-Loaded PLGA Foams -- a New Implant Material for Controlled Release of Chemotherapeutic Agents
(2007-01)Supercritical gas foaming using CO₂ was used to fabricate blank poly DL lactide-co-glycolide (PLGA) micro-porous foams. Paclitaxel-loaded PLGA foams were also produced for the first time using a modification of the ... -
MicroRNAs Modulate Hematopoietic Lineage Differentiation
(2005-01)MicroRNAs (miRNAs), an abundant class of ~22 nucleotide non-coding RNAs, are thought to play an important regulatory role in animal and plant development at the posttranscriptional level. Many miRNAs cloned from mouse bone ... -
Mining Of Text In The Product Development Process
(2002-01)In the prevailing world economy, competition is keen and firms need to have an edge over their competitors for profitability and sometimes, even for the survival of the business itself. One way to help achieve this is the ... -
Mobile P2Ping: A Super-Peer based Structured P2P System Using a Fleet of City Buses
(2005-01)Recently, researchers have introduced the notion of super-peers to improve signaling efficiency as well as lookup performance of peer-to-peer (P2P) systems. In a separate development, recent works on applications of mobile ... -
A Model for Contingent Manpower Planning: Insights from a High Clock Speed Industry
(2003-01)Intense competitive pressures have led to compressed product life cycles and frequent introduction of new products. This creates demand volatility and a consequent pressure on manufacturing to meet this variable demand. ... -
Model Order Reduction for Determining Bubble Parameters to Attain a Desired Fluid Surface Shape
(2005-01)In this paper, a new methodology for predicting fluid free surface shape using Model Order Reduction (MOR) is presented. Proper Orthogonal Decomposition combined with a linear interpolation procedure for its coefficient ... -
Model reduction for active control design using multiple-point Arnoldi methods
(2003-01)A multiple-point Arnoldi method is derived for model reduction of computational fluid dynamic systems. By choosing the number of frequency interpolation points and the number of Arnoldi vectors at each frequency point, the ... -
