Ownership unbundling in electricity distribution: The Russian experience
(Elsevier, 2018-10-15)
Russia is the first and thus far only country that has separated ownership of electricity distribution and transmission and then, a few years later, reunified these services under one company. We examine the impact of these ...
Effect of Converter Topology on the Specific Energy Consumption of Alkaline Water Electrolyzers
(IEEE, 2018-10-17)
Water electrolysis will be used to produce renewable hydrogen for energy storage and Power-to-X applications in the future renewable-energy-based energy systems. Therefore, the energy efficiency of hydrogen production will ...
Pattern recognition algorithm for analysis of chugging direct contact condensation
(Elsevier, 2018)
Direct contact condensation of steam bubbles in a boiling water reactor suppression pool has long been studied utilizing video recording of experiments. The use of video recording enables observation of the behaviour of ...
Product Processes based on Digital Twin
(Springer Vieweg, Wiesbaden, 2018-05-03)
Product development is performed by accomplished designers who make their best efforts to understand customer needs and desires via verbal or written feedback. This approach becomes cumbersome if a product design undergoes ...
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 ...
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 ...
A framework of disruptive sustainable innovation: an example of the Finnish food system
(Taylor & Francis, 2018-11-26)
Disruptive innovations are perceived necessary for accelerating sustainability transitions. However, it is not always clear what exactly is meant by it, what is to be disrupted, and by whom. Socio-technical transition ...
Feasibility of 100% renewable energy-based electricity production for cities with storage and flexibility
(Elsevier, 2018-11-16)
Renewable energy is expected to constitute a significant proportion of electricity production. Further, the global population is increasingly concentrated in cities. We investigate whether it is possible to cost-effectively ...
On the design of fillet welds made of ultra-high-strength steel
(Springer Berlin Heidelberg, 2018-07-12)
Current static design approaches for fillet arc welds made of high- or ultra-high-strength steel (UHSS) do not differ from the design of welds made of conventional steels. However, important issues such as potential softening ...
