Energy Measurement of Electric Fence

, 2011
Syftet med denna rapport är att få en inblick hur elstängselaggregat fungerar och hur energimängden, från en stöt, noterar. Det har då tagits fram en förstudie om vilka elstängselaggregat och vilka mätinstrument som ska användas. Mätningar har gjorts både i laborationsmiljö och ute i jordbruksmiljö. En enklare funktion och uppbyggnad har undersökts och

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Analysis on Energy Consumption of Building Electricity and Energy Saving Measures

Advances in Energy and Power Engineering, 2017
我国建筑能耗大，节能建筑比例小，建筑节能不能忽视。民用建筑使用能耗中，建筑电气能耗所占比例大，建筑节能主要在于电气节能。电气能耗主要包括供配电系统、电力电缆、照明、电机系统中。文章介绍了建筑电气节能原则，进行能耗分析，在此基础上提出了现实切实可行的电气节能措施。 China’s building energy consumption is large, and the proportion of building energy-saving is small. Building energy efficiency cannot be ignored.

High‐Temperature Phase Transformation in a V‐9Si‐6.5B Alloy: The Kinetic and Crystallographic Pathway From V5SiB2 to V8SiB4

Advanced Engineering Materials, EarlyView.
In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

Advanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.
