This study explores the optimization of electricity supply to mobile base station with the modelling of a hybrid system configuration in Accra, the capital city of Ghana. The hybrid system deployed is to enhance sustainability, ...

The majority of manufacturing companies are increasingly focused to decreasing product development time, costs, and introduction time to market. As a result of virtual simulation implementation to product engineering, SDPD ...

The study describes an advanced road management system delivering suggestions about the route in the domain of one subunit. It also does pricing on the lane time. The length of the domain is about 100 m, i.e. the distance ...

Screw conveyors are the fourth biggest energy consumption group of industrial electrical motors. In this thesis, sensorless frequency converter systems are researched with main objective in maximizing energy efficiency. ...

The continuous rise in electricity demand across the globe has been a major source of carbon dioxide (CO2) emissions and other gases such as greenhouse gases (GHGs) resulting from the excessive use of crude oil and fossil ...

Monet sähkömoottoreilla toimivat pumppujärjestelmät ovat vaikeissa paikoissa huollon kannalta. Niiden kunnosta ja toiminnasta olisi kuitenkin hyvä pitää tarkkaa seurantaa, sillä vikaantuessaan ne voivat aiheuttaa suuria ...

This Master’s Thesis presents a dynamic core-annulus model of circulating fluidized bed (CFB) boilers which is implemented in Apros simulation software. In describing and verifying the model, the focus is on the solids ...

The demand for higher rotational speeds and the more and more challenging work environments have pushed magnetic bearings and bearingless machines to be an extensive multidisciplinary field of research. Magnetic bearings ...

The crystallization process has a great significance in different industries worldwide. It is widely used to produce various products - from bulk chemicals to pharmaceutical ingredients and food additives. Most of the ...

ABB Virtual Drive is a software tool for simulating electric drive system. In this thesis different use cases and challenges for this software were studied. New and improved electric drive simulator was created and integrated ...
