Composite sorbents based on silica, polyethylene glycol (PEG) and containing calcium chloride were successfully synthetized using the sol-gel method. Their heat storage performance was investigated in a lab-scale open fixed-bed reactor. The silica/PEG matrix managed to stabilize hydrated when salt content equal 32 wt% despite partial deliquescence. presence of crystallized phase CaCl2/PEG resul...

Until the last decade, performance of HPC architectures has been almost exclusively quantified by their processing power. However, energy efficiency is being recently considered as important as raw performance and has become a critical aspect to the development of scalable systems. These strict energy constraints guided the development of a new class of so-called light-weight manycore processor...

The effect of the duration adsorption step and purge flowrate on performance a demand-driven pressure swing unit (PSA) was investigated. These two operating parameters were varied examined by simultaneously varying requested total productivities (demand) using model for biogas upgrading. considered PSA application uses FAU zeolite (13X) to separate CH4 CO2. is tracked three key indicators (KPIs...

Sobel is one of the most popular edge detection operators used in image processing. To date, users utilize two-directional 3×3 operator as detectors because its low computational cost and reasonable performance. Simultaneously, many studies have been conducted on using large multi-directional to satisfy their needs considering high stability, but at an expense speed. This paper proposes a fast ...

The gas SF6 has become of interest as a negative ion drift gas for use in directional dark matter searches. However, as for other targets in such searches, it is important that radon contamination can be removed as this provides a source of unwanted background events. In this work we demonstrate for the first time filtration of radon from SF6 gas by using a molecular sieve. Four types of sieves...

We present an empirical study of novel work-optimal parallel algorithms for Burrows-Wheeler compression and decompression of strings over a constant alphabet. To validate these theoretical algorithms, we implement them on the experimental XMT computing platform developed especially for supporting parallel algorithms at the University of Maryland. We show speedups of up to 25x for compression, a...
