(2022-04-05)In this study the effect of repeated injection molding cycles on the structure and properties of polyamide 6/polyamide 66/talc (PA6/PA66/talc - 35/35/30) composite was investigated for samples subjected to one, four, and ... -
Comparison among exergy analysis methods applied to a human body thermal model
(2022-01-15)© 2021 Elsevier LtdOver the past decades, thermodynamics concepts applied to biological systems, such as the human body, have aided in explaining their functioning. The first law of thermodynamics is primarily used — from ... -
Predictive and descriptive approaches to learning game rules from vision data
(2006-10-23)Systems able to learn from visual observations have a great deal of potential for autonomous robotics, scientific discovery, and many other fields as the necessity to generalise from visual observation (from a quotidian ... -
Channel length influence on the performance of source-follower buffers implemented with graded-channel SOI nMOSFETs
(2008-09-04)This work presents an evaluation of the influence of channel length on the performance of graded-channel (GC) SOI nMOSFETs operating as source-follower buffers. Experimental data is used to compare the buffer gain and ... -
