Developing a standard measurement and calculation procedure for high brightness LED junction temperature
(2014)
White light emitting diodes (LEDs) are appearing in general illumination applications. Clusters of such LEDs can replace an incandescent light bulb of equal luminosity on the merit of considerably low power consumption. ...
Analysis of near-field radiation transfer within nano-gaps using FDTD method
(Elsevier, 2014-10)
Enhancement of near-field radiative emission via coupling of surface plasmons in nano-gaps formed between thin films is important for understanding and implementation of energy harvesting using nano-thermophotovoltaic ...
An investigation into momentum and temperature fields of a meso-scale slot synthetic jet for a small jet-to-surface spacing
(Begell House Inc., 2014)
Impinging synthetic jets have been identified as a promising technology for cooling miniature structures. Recognizing their thermal performance on the target surface requires a fundamental understanding of the momentum ...
Hybrid job scheduling for improved cluster utilization
(Springer Science+Business Media, 2014)
In this paper, we investigate the models and issues as well as performance benefits of hybrid job scheduling over shared physical clusters. Clustering technologies that are currently supported include MPI, Hadoop-MapReduce ...
Improving selectivity on germanium CMP applications
(ECS, 2014)
In the presented paper, the adsorption characteristics of cationic and anionic surfactants on germanium and silica were studied in order to improve selectivity in germanium based shallow trench isolation chemical mechanical ...
Quasistatic nonlinear viscoelasticity and gradient flows
(Springer Science+Business Media, 2014)
We consider the equation of motion for one-dimensional nonlinear viscoelasticity of strain-rate type under the assumption that the stored-energy function is λ-convex, which allows for solid phase transformations. We formulate ...
Constrained min-cut replication for k-way hypergraph partitioning
(Informs, 2014)
Replication is a widely-used technique in information retrieval and database systems for providing fault tolerance and reducing parallelization and processing costs. Combinatorial models based on hypergraph partitioning ...
A computational and experimental study on a harsh environment LED system for vehicle exterior lighting applications
(IEEE, 2014)
Effect of compact thermal packaging approaches and challenges are investigated for a next generation automotive LED lighting. A challenging three-purpose in one (3i1) highly packaged light emitting diodes (LEDs) lighting ...
An investigation into momentum and temperature fields of a meso-scale synthetic jet
(IEEE, 2014)
Thermal management has become a critical part of advanced micro and nano electronics systems due to high heat transfer rates. More constraints such as compactness, small footprint area, lightweight, high reliability, ...
Near-optimal modified base stock policies for the capacitated inventory problem with stochastic demand and fixed cost
(World Scientific Publishing, 2014-06)
In this study, we investigate a single-item, periodic-review inventory problem where the production capacity is limited and unmet demand is backordered. We assume that customer demand in each period is a stationary, discrete ...
