Packet Switched UMTS Pilot System

Universal Mobile Telecommunication System (UMTS) on Third Generation Partnership Project (3GPP) –organisaation määrittelemä matkaviestinjärjestelmä. UMTS tukee sekä piiri- että pakettikytkentäistä tiedonsiirtoa ja mahdollistaa langattoman, suurinopeuksisen Internet-yhteyden. Diplomityön tarkoituksena on kuvata Nokia Research Center:n toteuttama kolmannen sukupolven 3GPP yhteensopiva pakettikytkentäinen koejärjestelmä. Työssä on käytetty uutta lähestymistapaa protokollakehitykseen, yhdistämällä eri työkaluilla tuotettuja protokollia yhdeksi kokonaisuudeksi. Liikenteen vaihtuessa lähitulevaisuudessa suurelta osin pakettikytkentäiseksi on mietittävä keinoja palvelunlaadun takaamiseksi. Näitä keinoja tutkittiin käyttämällä työssä toteutettua koejärjestelmää testialustana. Koejärjestelmää esiteltiin useissa konferensseissa ja se toimitettiin monille teleoperaattoreille.

Pneumatic Conveying of Granular Materials in a Pilot Scale Downer-Riser System

Studies regarding the field of this work aim to substitute industrial mechanical conveyors with pneumatic conveyors to overcome the disadvantages in solids flow regulation and risks posed to production and health. The experimental part of this work examines how the granular material properties, fluidizing airflow rate, equipment geometry, and pressures along the pipes affect the mass flow rate through the system. The results are compared with those obtained from previous experiments conducted with alumina. Experiments were carried out with a pilot scale downer-riser system at Outotec Research Center Frankfurt. Granular materi-als used in this work are named as sand, ilmenite, iron ore 1 and iron ore 2.

Feasibility study of submerged membrane bioreactor (MBR) as an alternative to conventional activated sludge process (CASP) for municipal wastewater treatment: A pilot scale study

The conventional activated sludge processes (CAS) for the treatment of municipal wastewater are going to be outdated gradually due to more stringent environmental protection laws and regulations. The Membrane bioreactors (MBRs) are the most promising modern technology widely accepted in the world of wastewater treatment due to their highly pronounced features such as high quality effluent, less foot print and working under high MLSS concentration. This research project was carried out to investigate the feasibility and effectiveness of MBR technology compare to the CAS process based on the scientific facts and results. The pilot scale MBR pilot plant was run for more than 150 days and the analysis results were evaluated. The prime focus of the project was to evaluate the correlation of permeate flux under different operating MLSS concentrations. The permeate flux was found almost constant regardless of variations in MLSS concentrations. The removal of micropollutant such as heavy metals, PCPPs, PFCs, steroidal hormones was also studied. The micropollutant removal performance of MBR process was found relatively effective than CAS process. Furthermore, the compatibility of submerged membranes within the bioreactor had truly reduced the process footprint.
