Urban flows is a new concept used in dependency analysis and therefore one of the aims is to investigate whether this concept is practically useful or if it is too comple

Voyage charterparties, as one of the most common carriage contracts, has its own specific provisions which govern the legal relationship of the engaged parties. One of those specifications relates to the concept of laytime which is defined as the time during which the charterer can load or discharge the cargo. In this work the author tries to discuss the requirements that should be fulfilled to co
The Japanese evidentials yooda and rashii both express inference, but it is difficult to articulate their difference. This paper presents a new theory that can explain the practical use of said evidentials, including cases that are problematic for previous research. A secondary use where they adjectivize a noun or predicate has also been taken into consideration, to avoid cross-contamination betwe
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
This thesis explores the gender earnings gaps in urban Ecuador during the period between 2003 and 2012. The difference between the female average earnings and the male average earnings increases from 7% in 2003 to 12% in 2012. Thus, exploring if this increase is a common pattern of the gender earnings gap across the distribution, the links between the gaps and occupational segregation, the differe
The importance of entrepreneurship in our society is the way it stimulate the markets through alertness to opportunities, and being creational of new opportunity-ideas. However, entrepreneurship is usually constrained by normative, regulative and cognitive mechanisms that enforces and forms the basis on which the entrepreneur operates.

In this work two versions of Oauth have been analyzed, the protocol OAuth 1.0a and the newer framework OAuth 2.0. A higher version number is often considered a good thing, but OAuth 2.0 has encountered much criticism. It has been criticised of not being safe enough while OAuth 1.0a was criticised of being very complicated protocol to implement, which has stopped it from growing as expected. The fo
Public transportation gets paralyzed every year when winter conditions occur and the purpose of this thesis has been to summarize experiences from tram cities, mainly in Scandinavia, and suggest solutions to the problems identified. Material was collected from Stockholm, Gothenburg, Norrköping, Oslo, Trondheim, Helsinki and Budapest. Operating the tramway during winter leads to problems specific t
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. The substantial delay effect may be due to the many different companies participating in the railway business, and the several technical components correla
Inverters synthesizing output voltages consisting of two levels, commonly known as two-level inverters, have dominated the global market for a long time. Today, further emphasis is being put on inverter efficiency and power quality. One way of improving these aspects is to use an inverter synthesizing a staircase voltage waveform consisting of three or more levels. Such inverters are known as mult
