Advanced dynamic simulation of different pumping methods in an AC-chilled water system
Gustafsson, Wilhelm (Åbo Akademi, 2018)The International Maritime Organization has introduced stricter energy efficiency demands to compel ship builders to further reduce emissions on, e.g., cruise ships. Heating, ventilation and air conditioning (HVAC) represents ... -
Application potential of an on-line ATP analyzer for process control
Jansson, Rasmus (2022)Continuous analysis of the microbiological load in water is still today a scarcely applied concept. Microbiological problems have been present in various scales in the process industry, but in conjunction with circular ... -
Data-based Wave Filtering Using Neural Networks with Application to Dynamic Positioning
Franz, Andreas (Åbo Akademi, 2018)Ships are constantly affected by environmental disturbances. Oscillating wave forces are one of these disturbances. In dynamic positioning applications, these wave disturbances lead to an oscillating motion of the ship ... -
Development of autonomous navigation systems for maritime applications
Storbacka, Mathias (2021)The interest in autonomous technology for transportation has grown significantly in the last decade and is slowly reaching the maritime industry as well. There are numerous potential benefits in using self-driving vehicles ... -
Estimation of Urea Dosage in an SCR Unit
Sandell, Ludvig (2021)Impositions of increasingly stringent restrictions on the harmful emissions of nitrogen oxides (NOx) from combustion engines have popularized the use of chemical exhaust gas treatment in the form of selective catalytic ...Kokoteksti on luettavissa vain Kirjatornissa ja Academill-kirjastossa. -
Fjärrvärmeproduktion från spillvärmeflöden vid UPM:s fabrik i Jakobstad
Hjulfors, Marcus (Åbo Akademi, 2020)I detta diplomarbete som gjordes i samarbete med UPM Jakobstad och Oy Herrfors Ab undersöktes möjligheterna att producera fjärrvärme till Herrfors Ab:s fjärrvärmenät i Jakobstad, från spillvärmeflöden som uppstår i samband ... -
Forecasting demand and inventory control for spare parts
Hyödynmaa, Maunu (Åbo Akademi, 2019)After sales services, especially the provision of spare parts, is not only a legal obligation but also a way of providing a competitive advantage for a business in a competitive market. However, at least for spare parts, ... -
Modular calculation and optimization toolkit for power plant applications
Nyman, Matias (2021)Automation is an ever-increasing phenomenon in today’s world, almost exponentially so. If a task is expected to be repeated in a predictable and quantifiable way, it will at some point be subject to automation. Naturally, ... -
Performance modeling of single-phase brazed plate heat exchangers
Högnabba, Kim (2021)The design of heat exchangers for specific applications entails a number of different calculations in order to determine the appropriate dimensions and characteristics for the heat exchanger unit. The relevant equations ... -
Proposal of a long-term water supply network to Honde Valley Ward 10
Eriksson, Jeremias (2022)The thesis provides a technical framework of gravitationally fed water distribution systems in rural developing regions. The functionality of gravity-fed networks’ theory includes energy profiles in the network, pressures ... -
Refiner Energy Optimization Utilizing Fiber Analyzer
Forslund, Atte (Åbo Akademi, 2020)New ways to monitor papermaking processes are developed constantly to improve electricity- and chemical consumption, and to minimize paper waste. The methods used today usually rely on the produced papers’ measured properties. ... -
Study of section & block outfitting to support production planning
Saranki, Toni (Åbo Akademi, 2019)This thesis focuses on providing more accurate and reliable data for production planning of section- and block outfitting in shipbuilding industry through specific installation time –measurements. Additionally, a current ...Embargo until 2024-02-05 -
