Laivamoottoripäästön hiukkasten haihtuvuus komponenteittain
(2018-06-06)Nykypäivinä laivaliikenteessä käytetyt moottorit ovat lähes aina dieselmoottoreita, joiden polttoaineena käytetään esimerkiksi raskasta tai keskiraskasta polttoöljyä. Toisaalta myös uudet ja ympäristöystävällisempinä pidetyt ... -
Käyttövarmuuden rakentaminen osaksi teollisuusrobotin soluohjainta
(2018-06-06)Ohjelma on käyttövarma kun se toimii määrittelynsä mukaisesti ja sen käyttö onnistuu sille asetettujen ehtojen vallitessa halutun ajan verran. Yhä monimutkaisempien ohjelmien osalta käyttövarmuuden varmistaminen on kuitenkin ... -
Vesijohto- ja jätevesiverkoston saneerausten priorisoinnin kehittäminen
(2018-06-06)Tämä diplomityö käsittelee vesijohto- ja jätevesiverkoston saneerausten priorisoinnin kehittämistä Helsingin seudun ympäristöpalvelut -kuntayhtymässä (HSY). Saneerausten priorisoinnin avulla pyritään kohdentamaan ... -
Termoelementtien hyödyntäminen hajautetussa sähkön ja lämmön yhteistuotannossa
(2018-06-06)Hajautetussa energiantuotannossa energia tuotetaan pienehköissä energiantuotantoyksiköissä ja yleensä lähellä kulutuskohdetta. Hajautetussa sähkön ja lämmön yhteistuotannossa eli CHP-tuotannossa sama laitteisto tuottaa ... -
Binder materials for modification of functional nanoparticle coating
(2018-06-06)There are lots of changes happening in the field of surface modification. The purposes of this thesis is to present a surface modification procedure that could be useful in producing durable coatings from nanoparticles. ... -
Production of Storage Lipids from Nitrogen-rich Substrate
(2018-06-06)Acinetobacter baylyi ADP1 is a bacterium capable of producing wax esters (WE) in nitrogen limited conditions. WEs are esters of fatty acids and fatty alcohols and they are used in e.g. cosmetics. Many fields of industry ... -
Simulation model for hydrothermal liquefaction reactions
(2018-06-06)Lately the production of biofuels from renewable sources has aroused interest due to the decreasing number of fossil fuels and preventing the climate change. Especially the replacement of fossil transportation fuels by ... -
Developing a product-service system for automation retrofit offering
(2018-06-06)It has been a growing trend for decades to replace human labour with automation. The goal is to increase productivity and worker safety while decreasing costs and human errors. However, investing on new, high technology ... -
Multi-cloud Security Mechanisms for Smart Environments
(2018-06-06)Achieving transparency and security awareness in cloud environments is a challenging task. It is even more challenging in multi-cloud environments (where application components are distributed across multiple clouds) owing ... -
Spectral Measurements of Second-Harmonic Generated Light
(2018-06-06)Nonlinear light-matter interactions can lead to second-harmonic generation (SHG) or frequency doubling of light. Previously, we have measured SHG from nanoparticle arrays using just one incident wavelength. In order to ... -
Heat management in high-efficiency photovoltaics
(2018-06-06)Multi-junction solar cells are one of the most promising technologies for solar energy production in both terrestrial and space applications. Highest conversion efficiencies among all solar cells have been recorded by III–V ... -
Studies on deoxygenation of decane-1,2-diol derivatives with pinacol-derived chlorohydrosilane
(2018-06-06)In spite of the extensive studies, which have been carried out on the selective deoxygenation of secondary alcohols, it still poses a formidable challenge. The recent discovery of the reduction of salicylaldehydes with a ... -
Secondary Organic Aerosol Formation From Polycyclic Aromatic Precursors
(2018-06-06)Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that are emitted into the atmosphere mainly through incomplete combustion of fossil fuels and biomass. The lifecycle of PAHs especially in urban atmosphere is ... -
