A controlled experiment was conducted at the Cold Region Research and Engineering Laboratory (CRREL) facilities for retrieving freshwater ice characteristics using a Frequency Modulated Continuous Wave (FM-CW) radar system. The purpose of this study is to quantify the interactions between a ...
First, interviews with six undergraduates explored their concepts of desirable learning companions. The interviews yielded agent competency, agent personality, and interaction control. Next, a controlled experiment examined whether learner competency (strong vs. weak) would relate directly to agent ...
摘要: We describe a very simple experiment that allows college students in introductory physics courses to plot the I-V characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor and light conversion efficiency....
Korhonen,Jenny A.,Gaspari,... - 《Journal of Biological Chemistry》 被引量: 234发表: 2003年 A Replicated Experiment to Assess Requirements Inspection Techniques This paper presents the independent replication of a controlled experiment which compared three defect detection techniques (Ad Hoc, Checklist...
[Reduction of the expansion rate of small abdominal aortic aneurysms with roxithromycin. Results from a randomized controlled trial] Macrolide treatment has been reported to reduce the risk of recurrent ischaemic heart disease. The influence of a macrolide on the expansion rate of small ... V Sten...
to study the failure mode and fracture evolution characteristics of red shale in Kaiyang Phosphorus mining area, conventional triaxial compression mechanical tests of red shale with different bedding dip angles were carried out by using DSTD-1000 electro-hydraulic servo rock mechanics experiment system. ...
Objective: This study investigated the effects of sexual arousal and sexual partner characteristics as determinants of HIV_ men who have sex with men's (MSM) intentions to engage in unprotected sex. Design: In a computer-based controlled experiment, 67 HIV_ MSM underwent a sexual arousal manipula...
We report the interfacial study of a silicon/carbon nanofiber/graphene composite as a potentially high-performance anode for rechargeable lithium-ion batteries (LIBs). Silicon nanoparticle (Si)/carbon nanofiber (CNF)/reduced graphene oxide (rGO) composite films were prepared by simple physical filtratio...
to find out whether or not it is valid. The environment must be carefull controlled so that extraneous elements do not intrude to invalidate the experiment, and so that others can repeat the experiment in the hope of arriving at the same result, which is the best evidence of its ...
. There is also a possibility that cholinergic sensitivity to body temperature increases (Henane and Bittel1975; Libert et al.1983). Moreover, it was discovered that the increase in the regional sweat rate on the limbs was higher than that on the torso. This suggests a redistribution of ...
