Interactions of rocks with supercritical CO2 and water in enhanced geothermal systems and beyond
As an alternative fluid, supercritical CO2 has been considered for its potential to yield up to 50% more electricity than water, mainly due its lower viscosity and greater ability to…

Improvement of silicon solar cell metallization with printed nickel nanoparticle ink
In this paper we will present two approaches for the frontside metallization of crystalline silicon solar cells, targettting on dramatically reducing the specific contact resistance between the metal gridline and…
-
Acoustic power recovery system for thermoacoustic cooling
We present a thermoacoustic cooler design that utilizes acoustic power recovery to make a coefficient of performance (COP) comparable to that of conventional systems possible.
-
Experimenting with fast private set intersection
This paper considers one (arguably, most efficient) PSI construct and reports on its optimized implementation and performance evaluation.

Modeling destructive group dynamics in on-line gaming communities
In this paper, we take the World of Warcraft game as an exemplar platform for studying destructive group dynamics.
-
Organic complementary decoder circuits patterned by inkjet printing for addressing memory elements
With all-printed solution processing, we have fabricated peripheral circuits required for addressing passive matrix arrays.
-
Formation of very low resistance contact for silicon photovoltaic cells
A number of approaches have been developed in order to introduce a nickel-based contact layer between the silver electrode and n+ emitter layer, which can substantially reduce the specific contact…

Why are you more engaged: factors influencing Twitter engagement in Occupy Wall Street
In this paper we explore factors that influence the engagement of Twitter users during the recent Occupy Wall Street movement, where engagement is measured by retweets and hashtag usage related…

Optical studies on homoepitaxial AlN
We investigated such layers by low-temperature photoluminescence (PL), reflectance, and ellipsometry.

Adaptive and Discriminative Modeling for Improved Mispronunciation Detection
In this work, we extend our approach with the use of model adaptation and discriminative modeling techniques, inspired on methods that have been effective in the area of speaker identification.

Trace Amine-Associated Receptor 1 Partial Agonism Reveals Novel Paradigm for Neuropsychiatric Therapeutics
Here we report on the identification and characterization of the first selective and potent TAAR1 partial agonist.

Effects of audio and ASR quality on cepstral and high-level speaker verification systems
We evaluate the effect that improved audio quality has for speaker verification performance, using a recently released full-bandwidth version of microphone data from the SRE2010 evaluation.
