A coupled system simulator, based on analytical circuit equations and a finite element method (FEM) model of the motor has been developed and it is used to analyse a frequency-converterfed industrial squirrel-cage induction ...

In the doctoral dissertation, low-voltage direct current (LVDC) distribution system stability, supply security and power quality are evaluated by computational modelling and measurements on an LVDC research platform. ...

This thesis presents a one-dimensional, semi-empirical dynamic model for the simulation and analysis of a calcium looping process for post-combustion CO2 capture. Reduction of greenhouse emissions from fossil fuel power ...

Biomass provides an excellent opportunity to increase the use of local resources and promote renewable energy generation. The considerable diversity of biomass materials and differences in their chemical structure require ...

The importance of industrial maintenance has been emphasized during the last decades; it is no longer a mere cost item, but one of the mainstays of business. Market conditions have worsened lately, investments in production ...

The tightening competition and increasing dynamism have created an emerging need for flexible asset management. This means that the changes of market demand should be responded to with adjustments in the amount of assets ...

Effective control and limiting of carbon dioxide (CO₂) emissions in energy production are major challenges of science today. Current research activities include the development of new low-cost carbon capture technologies, ...

Crystal growth is an essential phase in crystallization kinetics. The rate of crystal growth provides significant information for the design and control of crystallization processes; nevertheless, obtaining accurate growth ...

Ni-Mn-Ga magnetic shape memory (MSM) alloys are considered to be highly promising materials for actuation, damping, sensing and energy harvesting applications, due to the unique combination of a large transformation strain ...

Hydrometallurgical methods are suitable for the treatment of primary, secondary, highand low-grade raw materials enabling the production of metals essential to modern society, in an environmentally and economically sustainable ...
