Nonlinear PI-control approach for improving the DC link voltage control performance of a power factor corrected system
(IEEE, 2018)
When fast voltage control is used in a power factor control, the ripple of the DC link causes current harmonics. This paper proposes a method to reduce the harmonic content of a fast voltage loop in a power factor correction ...
Linking the unlinked: knowledge-based perspective on non-routine change
(Emerald Group Publishing Limited, 2013)
Purpose
– Firms operating in contemporary hypercompetitive environments have to seek series of temporary advantages, sometimes requiring them to move beyond their current knowledge domains. The existing knowledge‐ and ...
The socio-psychological challenges of succession in family firms: The implications of collective psychological ownership
(Springer Nature, 2018-09-06)
One of the most distinct challenges that family businesses face is succession. Several researchers have recognized that it is not a single event, but a process associated with social and psychological challenges. This ...
Recovering rare earth elements from phosphogypsum using a resin-in-leach process: Selection of resin, leaching agent, and eluent
(Elsevier, 2019-08-10)
Phosphogypsum (PG) is an attractive secondary raw material for rare earth elements (REEs) because it is abundant and contains significant amounts of REEs. Herein, the resin-in-leach (RIL) process for REE recovery from PG ...
Owners of second homes, locals and their attitudes towards future rural wind farm
(Elsevier, 2014-10)
Wind power has been identified as one of the most promising sources of renewable energy. However, its diffusion has not been as rapid as anticipated. The objective here is to analyse attitudes towards wind power among ...
Experimentation on Wind Powered Hydraulic Heating System
(IEEE, 2018-09-27)
It is common knowledge of the world’s dependency on fossil fuel for energy, its unsustainability on the long run and the changing trend towards renewable energy as an alternative energy source. This aims to cut down ...
Acoustic Detection of Cracks and Delamination in Multilayer Ceramic Capacitors
(IEEE, 2018-10-04)
Multilayer Ceramic Capacitors (MLCC) are the most widely used capacitor type in the electronics industry. However, the brittle ceramic dielectric makes MLCCs prone to mechanical damage. Manufacturing defects or damage ...

(Springer, 2017)
This chapter presents an analysis of how the new Russian support policy for renewable energy investments changes the expected profitability of renewable energy investments in Russia. A comparative analysis of investment ...
Insights into a membrane contactor based demonstration unit for CO2 capture
(Elsevier, 2019-08-16)
A continuously operated CO2 capture unit, based on absorption in a membrane contactor and low-temperature vacuum desorption, is demonstrated. The major advantage of membrane contactors is their high specific interfacial ...
Long term load projection in high resolution for all countries globally
(Elsevier, 2019-04-13)
