Freeloader: an Open Source Universal Testing Machine for High-throughput Experimentation
نویسندگان
چکیده
We present a low cost, desktop size, open source, universal testing machine, designed for inexpensive high-throughput material testing. The tester can apply tensile and compressive loads up to 5 kN at rates ranging from 2 mm/min to 30 mm/min. Force measurements are achieved with ±1.8 N accuracy. The parts list for this machine represents an order of magnitude reduction in the cost per testing unit as compared to commercial systems. We describe the design and construction of the tester and validate its performance. The design, parts list, control software, and user manual are made available freely online under the open source

NEXT: A System for Real-World Development, Evaluation, and Application of Active Learning
Active learning methods automatically adapt data collection by selecting the most informative samples in order to accelerate machine learning. Because of this, real-world testing and comparing active learning algorithms requires collecting new datasets (adaptively), rather than simply applying algorithms to benchmark datasets, as is the norm in (passive) machine learning research. To facilitate...
متن کاملWireless Coexistence and EMC of Bluetooth and 802.11b Devices in Controlled Laboratory Settings
This paper presents experimental testing that has been performed on wireless communication devices as victims of electromagnetic interference (EMI). Wireless victims included universal serial bus (USB) network adapters and personal digital assistants (PDAs) equipped with IEEE 802.11b and Bluetooth technologies. The experimental data in this paper was gathered in an anechoic chamber and a gigahe...
متن کاملMMR: a tool for read multi-mapper resolution
MOTIVATION Mapping high-throughput sequencing data to a reference genome is an essential step for most analysis pipelines aiming at the computational analysis of genome and transcriptome sequencing data. Breaking ties between equally well mapping locations poses a severe problem not only during the alignment phase but also has significant impact on the results of downstream analyses. We present...
متن کاملCancerDiscover: A configurable pipeline for cancer prediction and biomarker identification using machine learning framework
Motivation: Use of various high-throughput screening techniques has resulted in an abundance of data, whose complete utility is limited by the tools available for processing and analysis. Machine learning holds great potential for deciphering these data in the context of cancer classification and biomarker identification. However, current machine learning tools require manual processing of raw ...
متن کاملExploration of the Customized Fixtures for the Evaluation of Three-point Bending Strength of Dental Resin Composites
Introduction: This study aimed to devise customized fixtures for the evaluation of three-point bending strength (TPBS) of resin-based dental composites (RBCs). Materials and Methods: A cube-shaped jig made out of wood with dimensions of 105×105×101 mm was prepared in this study. A 20-mm-diameter hole was made in the center of the wooden jig. In addition, a stai...
