The Effects of Oil Entrained Air on the Dynamic Performance of a Hydraulically Driven Multibody System
(Praise Worthy Prize, 2020-10)
In co-simulation, a number of subsystems sharing details of a system, are coupled to exchange data. The subsystem level development of each package enhances the computational efficiency, and more sophisticated packages can ...
Review of the State-of-the-Art on Adaptive Protection for Microgrids based on Communications
(IEEE, 2020-07-03)
The dominance of distributed energy resources in microgrids and the associated weather dependency require flexible protection. They include devices capable of adapting their protective settings as a reaction to (potential) ...
Demonstrating the Impact of LTE Communication Latency for Industrial Applications
(IEEE, 2020-01-30)
This paper assesses the performance of a private LTE wireless network in an industrial automation setup. Our goal is to study the impact of communication latency in a robot arm position control application when the position ...
Measurement Accuracy Requirements for the Efficiency Classification of Converters and Motors
(IEEE, 2019-11-28)
Electrical machines play a major role in the electrical energy consumption in the modern world; therefore, the efficiency of electrical machines has been regulated for a long time by different authorities. Recently, the ...
Power quality and reactive power of water electrolyzers supplied with thyristor converters
(Elsevier, 2020-03-28)
Industrial water electrolyzers apply direct current in kiloampere ranges. Therefore, rectifiers are typically based on thyristors despite the high amplitude current fluctuation excited by the rectifier. This paper studies ...
Predictive Analytics in a Pulp Mill using Factory Automation Data—Hidden Potential
(IEEE, 2020-01-30)
Industrial automation systems have collected vast amounts of data for years. Data analytics and machine learning can be used to reveal different phenomena and anomalies, which may be otherwise impossible to see. However, ...
Effects of energy retrofits on Indoor Air Quality in multifamily buildings
(John Wiley & Sons, 2019-03-28)
Abstract
We assessed 45 multifamily buildings (240 apartments) from Finland and 20 (96 apartments) from Lithuania, out of which 37 buildings in Finland and 15 buildings in Lithuania underwent energy retrofits. Building ...
Experimental Investigation of a 75 kW Induction Motor Drive System Losses and Efficiency
(IEEE, 2019-12-09)
The frequency converter driven IM can be used as a reference for the efficiency level of a drive system. In here, the losses and efficiency of a 75 kW IE3 -rated modern squirrel-cage induction motor are investigated ...
Bond characteristics between high/ultra-high strength steel and ultra-high modulus CFRP laminates
(Elsevier, 2019-12-24)
With the increasing applications of high and ultra-high strength steel (HSS/UHSS) in engineering structures, there is a need to address rehabilitation and strengthening of such steel grades using carbon fibre reinforced ...
Global scenarios for significant water use reduction in thermal power plants based on cooling water demand estimation using satellite imagery
(Nature Publishing Group, 2019-11-25)
Connecting research on the water demand of power plants with mitigation strategies for energy-based water use is an important step to ensure global water and energy security, and thus provide more sustainable use of both. ...
