Evaluation of Darcy Flow Velocities Obtained from Borehole Dilution Tests

Från avrinningsområdet Donauried-Hürbe i södra Tyskland pumpas varje dag grundvatten som renas och levereras som dricksvatten till cirka tre miljoner människor i bland annat städer som Stuttgart och Ulm. Området kring den 200 meter djupa karstakvifären, ifrån vilken dricksvattnet härstammar, är idag miljöpåverkad av mänsklig aktivitet såsom jordbruk och fordonstrafik. För att minimera föroreningsrThe project is part of a larger investigation of the water protection area Donauried-Hürbe. This area is a recharge zone used by one of Germany’s biggest water supply companies, the Zweckverband Landwasserversorgung (LW). The freshwater supply originates from a 200 m thick karst aquifer in the Swabian Alb (Schwäbische Alb) and flows southest towards the Donauried and into a porous aquifer. The lon

Machine Learning för smartare pendling

Vid resor med kollektivtrafik finns det applikationer där en resenär kan söka efter resor. Resorna presenteras i en lista som oftast är sorterad efter avgångstid eller ankomsttid, vilket inte alltid stämmer överens med hur en resenär faktiskt väljer sina resor. Examensarbetet syftar till att utvärdera om det är möjligt att utveckla en maskininlärningsmodell som istället sorterar resorna utifrån reWhen traveling with public transport there is nowadays applications where a traveler can search for trips. The trips is presented as a list and is most often sorted by departure time or arrival time, which not always matches how a traveler actually chooses his trips. This thesis aims to test if it is possible to develop a machine learning model that instead sorts the trips by how a traveler has ch

Utilizing Machine Learning for Trading Algorithms Exploiting the Time Series Momentum Anomaly

Momentum or trend following investing refers to trading strategies constructed around the idea that in financial markets, the current trend will, more often then not, prevail. In the context of asset prices, this means that previous returns or the price development of an asset is indicative of similar future returns and price development. While at odds with established theory such as the weaker fo

Fukt- och temperaturrörelser i fasad- och vindskyddsskivor

Användningen av fasad- och vindskyddsskivor i ytterväggskonstruktioner är i dag utbredd. Skivorna är monterade långt ut i ytterväggen och utsätts således för variationer i omgivande relativ fuktighet och temperatur. På senare tid har skador såsom buktning av skivorna och sprickbildning hos skivorna uppmärksammats. Skadorna kan bero på rörelserna hos skivorna och det är således av intresse att undeThe use of boards as facades and sheathing is today common practice. Facade and sheathing boards are located far out in the building envelope and are thus subjected to variations of the surrounding relative humidity and temperature. Recently different kinds of damage on the boards have been brought to attention. The damage is varying and include cracking or warping of the boards. The damage may de
