Understanding affordance is a bottom-up process that lets simple visual features be used as clues on how to use an object, so that reasonable interactions with objects can be achieved, without any semantic knowledge. Linear splines are proposed as a way for robots to fast and continuously learn how their actions affect their surroundings. The general conclusions that they can draw from only little

In a wastewater treatment plant, particles (activated sludge) are separated from the liquid in a process called continuous sedimentation. This process is of crucial importance when purifying water in a wastewater treatment plant. This report will focus on a special case of sedimentation, namely batch sedimentation, which means that no flux into or out from the sedimentation tank are present. The g

In this work two versions of Oauth have been analyzed, the protocol OAuth 1.0a and the newer framework OAuth 2.0.

The number of reported errors on the catenary is relatively few in comparison with errors relating to the remaining parts of the railway system. This is an interesting fact, as errors linked to the catenary causes 30% of the total train delays.

Efter några år upptäckte däre

Korruption i internationella affärstransaktioner har blivit ett allt mer omfattande problem då den gränsöverskridande handeln har ökat. Korruptionen ökar transaktionskostnader, ställer upp hinder för fri handel och leder till ineffektivitet i form av nepotism och brist på transparens. Detta leder till att korruptionen orsakar fattigdom, instabilitet och tvister. En fördjupad förståelse om korrupt
