Fit of screw-retained fixed implant frameworks fabricated by different methods: a systematic review.
PURPOSE The aim of this study was to review the published literature investigating the accuracy of fit of fixed implant frameworks fabricated using different materials and methods. MATERIALS AND METHODS A comprehensive electronic search was performed through PubMed (MEDLINE) using Boolean operators to combine key words. The search was limited to articles written in English and published throu...
Apache Hadoop and Spark are gaining prominence in Big Data processing and analytics. Both of them are widely deployed on Internet companies. On the other hand, high-performance data analysis requirements are causing academical and industrial communities to adopt state-of-the-art technologies in HPC to solve Big Data problems. Recently, we have proposed a key-value pair based communication libra...
This work explores the use of big data technologies deployed in the cloud for processing of astronomical data. We have applied Hadoop and Spark to the task of co-adding astronomical images. We compared the overhead and execution time of these frameworks. We conclude that performance of both frameworks is generally on par. The Spark API is more flexible, which allows one to easily construct astr...
Task-based programming has proven to be a suitable model for high-performance computing (HPC) applications. Different implementations have been good demonstrators of this fact, and have promoted the acceptance of task-based programming in the OpenMP standard. Furthermore, in recent years, Apache Spark has gained wide popularity in business and research environments as a programming model for ad...
Plasma-Assisted Combustion (PAC) has shown potential in improving the ignition, extinction, and dynamic performance of combustion systems. In this work, nanosecond repetitively pulsed (NRP) spark discharges are applied to extend lean blow out (LBO) limit SICCA-Spray burner. This laboratory-scale atmospheric test rig is equipped with a swirl spray injector representing an idealized fashion singl...
The objective of the present work is to evaluate whether variable ignition timing can be effect on exhaust emission and engine performance of a spark ignition engine. The study describes some results of research in the area of spark ignition engine and is assessed by studying its performance and emission characteristics relative to that of conventional ignition engine using gasoline and methano...
We report on the results of an extensive R&D program aimed at the evaluation of Thick-Gas Electron Multipliers (THGEM) as potential active elements for Digital Hadron Calorimetry (DHCAL). Results are presented on efficiency, pad multiplicity and discharge probability of a 10x10 cm 2 prototype detector with 1 cm 2 readout pads. The detector is comprised of singleor double-THGEM multipliers coupl...
