Erityisen tuen toimintaprosessien nykytila ja kehittäminen suomalaisessa oppisopimuskoulutuksessa
(Lappeenranta University of Technology, 2018-10-12)
Oppisopimuskoulutus on käytännönläheinen ja kustannustehokas koulutusmuoto ammatillisen tutkinnon ja työelämän vaatiman osaamisen hankkimiseksi. Oppisopimuskoulutuksessa oppiminen ja kouluttautuminen tapahtuvat oikeissa ...
Big Data – Towards Data-driven Business
(Lappeenranta-Lahti University of Technology LUT, 2019-04-12)
This research stems from the disruptive phenomenon known as digital transformation, i.e. the pervasive use of digital technologies in order to add value in business. As a side effect of digital transformation, vast amounts ...
Quantification of large steam bubble oscillations and chugging using image analysis
(Lappeenranta-Lahti University of Technology LUT, 2019-11-01)
The pressure suppression pool of a boiling water reactor as a safety system has vital importance from the nuclear reactor safety point of view. If a loss-of-coolant accident occurs, a large amount of steam is pushed through ...
Supercritical CO2 Numerical Modelling and Turbomachinery Design
(Lappeenranta-Lahti University of Technology LUT, 2019-04-16)
Supercritical CO2 Brayton cycles have attracted significant attention in recent years on the basis that they can achieve higher thermal efficiency at relatively lower turbine inlet temperature in comparison to conventional ...
Agent-based modelling for epidemiological applications
(Lappeenranta-Lahti University of Technology LUT, 2019-03-29)
Malaria is an infectious disease induced by protozoan parasite called Plasmodium and transmitted by Anopheles mosquitoes which still imposes a health threat to virtually half of the human populace and causes severe mortality, ...
Agent-Based Modeling as Part of Biomass Supply System Research
(Lappeenranta-Lahti University of Technology LUT, 2019-06-14)
Interest in the use of agent-based modeling (ABM) for studying biomass supply systems has increased because of its flexible and cost-efficient nature. While ABM has been around for a long time, recent developments in ...
Losses in low-Reynolds-number centrifugal compressors
(Lappeenranta University of Technology, 2018)
Micro-scale centrifugal compressors and compressors operating at a high altitude suffer from performance deterioration due to low Reynolds numbers. An improvement in the efficiency of a low-Reynolds-number centrifugal ...
Improving the environmental safety of ash from bioenergy production plants
(Lappeenranta University of Technology, 2018-12-14)
Each year, energy production plants in Eastern Finland produce just under 100,000 tonnes of different types of ash and slag in the process of energy production. The utilisation of energy production ash flows has made ...
International trade in biomass for energy production: The local and global context
(Lappeenranta University of Technology, 2018-08-31)
Biomass is an important source of renewable energy in the global energy mix. International trade in biomass is increasing. It is stimulating global use of biomass for energy and promoting development of bioenergy in many ...
Synthesis and optimization of Kraft process evaporator plants
(Lappeenranta-Lahti University of Technology LUT, 2021-03-09)
In this dissertation, a novel methodology based on process superstructures for the synthesis and optimization of multiple-effect evaporation systems is described. The methodology allows for the structure and heat transfer ...
