MATLAB-Based Tool for Teaching of Active Magnetic Bearing Design to Undergraduate Students
(IEEE, 2018-11-08)
Visual educational tools are important in contributing to skills in the electrical engineering profession. This paper introduces an active magnetic bearing (AMB) design tool used to teach important skills in modern high-speed ...
Active residential customer in a flexible energy system — a methodology to determine the customer behaviour in a multi-objective environment
(Lappeenranta University of Technology, 2018-12-05)
The transformation from passive into active end customers in modern energy systems has already started in many European countries, and it is a long process. The first step to engage residential customers to be active actors ...
Improved banded method for spectral thermal radiation in participating media with spectrally dependent wall emittance
(Elsevier Ltd., 2018-11-17)
To develop an efficient and practical spectral radiation model for CFD simulations, a banded approach is proposed for a mixture of carbon dioxide and water vapor in varying thermodynamic states. Using a previously reported ...
Motion Synchronization of Biaxial Linear Tooth Belt Drive System
(IEEE, 2018-11-08)
Many manufacturing processes depend on accurate multi-axis movements. Development of drive technology has replaced the need of mechanical couplings and cams in synchronized manufacturing operations. In this paper motion ...
Localization of dielectric breakdown defects in multilayer ceramic capacitors using 3D X-ray imaging
(Elsevier, 2018)
In this article, a non-destructive method using 3D X-ray imaging to find dielectric breakdowndefects in multilayer ceramic capacitors (MLCCs) aged by high temperature and high voltage in an accelerated test is presented. ...
Study on properties related to energy recovery from waste streams in Finland
(Taylor & Francis, 2017-09-01)
Current paper presents the results of proximate analysis and heating value measurements for several different municipal solid waste (paper, cardboard, waste wood, textile, juice box carton and sewage sludge) and industrial ...
Fiber laser and hybrid welding of T-joint in structural steels
(Lappeenranta University of Technology, 2018-12-14)
Laser welding processes are amongst the most versatile joining technologies, suitable for both, small scale and mass production. The advancements in laser sources and optics is allowing autogenous laser beam welding to ...
Active sustainability actors: A life course approach
(John Wiley & Sons, Inc., 2019-08-20)
There is increasing interest in the role of actors in the pursuit of sustainability transitions. In this paper, we adopt a life course perspective to explore active sustainability actors. To this end, we interviewed 16 ...
Separation efficiency and ice strength properties in simulated natural freezing of aqueous solutions
(Elsevier, 2019)
In geographical regions with sub-zero temperatures, natural freezing can potentially be used as an energy-efficient purification technique for industrial wastewaters. The utilization of this technique requires knowledge ...
Influence of surface waviness in the heat generation and thermal expansion of the touchdown bearing
(Elsevier, 2018)
In an active magnetic bearings (AMBs) supported rotor system, the touchdown bearings have been proposed to support the rotor during an electromagnetic field shortage. The heat generation due to the high impact and collision ...
