Treatment of mining waters by electrocoagulation
(Lappeenranta-Lahti University of Technology LUT, 2020-02-21)
The mining industry is known to be one of the major contributors to the pollution of aquatic systems. The presence, in mining water, of various contaminants in relatively high concentrations (the most common cations being ...
Käyttäjät liikuntapalvelujen kehittäjinä – käyttäjälähtöisessä palveluinnovaatioprosessissa käyttäjien tuottama tieto tutkimuksen kohteena
(Lappeenrannan-Lahden teknillinen yliopisto LUT, 2020-01-17)
Suomalaiset liikkuvat terveytensä kannalta liian vähän. Ihmisten liikkumista on edistetty useilla eri tavoilla. Kansanterveyden näkökulmasta liikkumisen edistäminen onkin välttämätöntä, jotta voitaisiin ennaltaehkäistä ...
Managerial cognitive structures, strategy frames, collective strategy frame and their implications for the firms
(Lappeenranta-Lahti University of Technology LUT, 2020-02-14)
The overall aim of this doctoral dissertation is to increase the understanding of the interconnection between the top managers, the firms, and the industry by investigating the managerial cognitive structures and their ...
The role of renewable energy based seawater reverse osmosis (SWRO) in meeting the global water challenges in the decades to come
(Lappeenranta-Lahti University of Technology LUT, 2020-11-25)
Renewable energy (RE) powered desalination is rapidly gaining interest as a means to augment the increasingly stressed global water supply. This thesis introduces and describes the ways in which 100% RE-based seawater ...
Synthesis and performance of metal-halide perovskites as new visible light photocatalysts
(Lappeenranta-Lahti University of Technology LUT, 2021-01-20)
Solar-light power, as a sustainable energy source, is renewable, inexhaustible, and available worldwide. The scientific and engineering interest in solar-light based technologies has grown exponentially as a cost-effective ...
What constrains the sustainability of our day-to-day consumption? A multi-epistemological inquiry into culture and institutions
(Lappeenranta-Lahti University of Technology LUT, 2021-01-27)
Environmental crises unfold. The conditions for life are threatened. Unsustainable ways of living pervade; change is called for. As consumption is an intrinsic part of the system in crisis, it can provide a window of ...
Power-to-methanol via membrane contactor-based CO2 capture and low-temperature methanol synthesis
(Lappeenranta-Lahti University of Technology LUT, 2020-12-04)

Variable-speed-drive-based monitoring and diagnostic methods for pump, compressor, and fan systems
(Lappeenranta-Lahti University of Technology LUT, 2021-02-05)
Pumps, fans, and compressors account for nearly a third of the global consumption of electricity. Variable-speed drives (VSD) enable energy-efficient capacity control of these devices, and have thus become a common component ...
Improved state observers and robust controllers for non-linear systems with special emphasis on robotic manipulators and electro-hydraulic servo systems
(Lappeenranta-Lahti University of Technology LUT, 2021-02-26)
In real world the motion control system are faced with two major problems.: 1) monitoring internal states of the system 2) generating the suitable control signal to reach a desired path and follow it with time. These ...
