A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. This so-called "massive MIMO" promises attractive gains in spectral efficiency with
Purpose The purpose is to increase the IKEA knowledge regarding production of custom made worktops at two German suppliers, providing an action plan for the suppliers of how to increase product quality as well as calculating the potential cost savings and the product cost structure. Methodology The project is performed as two case studies, where both qualitative and quantitative data has been obta
The worsening of psychical health issues among young people has widely been discussed over the last few years. Research shows for example that 9% of girls at the age of 16-24 reported anxiety problems in 1989 while 16 years later, in 2005, the same number was 30%. The purpose of this essay was to study and analyze psychiatrists', psychologists' and counselors' view on the resilience an
This study examines whether the Kimberley process has succeeded to halt the spread of conflict diamonds to promote civil conflicts as well as if the Kimberley process has succeded to prevent human rights violations related to the diamond industry. The purpose of this study is to clarify whether the Kimberley process needs to be improved and whether the Kimberley process may precede as a model to i
Är en arbetstagare i arbetsrättslig mening alltid arbetstagare i skatterättslig bemärkelse, och tvärtom? Och vad är egentligen en F-skattare i juridisk mening? På det arbetsrättsliga området är arbetstagarbegreppet av mycket central betydelse. Tillämpligheten av de arbetsrättsliga lagarna utgår från arbetstagarbegreppet. Dessa lagar är utformade som skyddslagstiftningar för arbetstagare eftersom Is the definition of employee according to Swedish labour law similar to the definition of employee according to Swedish tax legislation? And what is the legal significance of approval of F-tax? The applicability of Swedish labour law is based on the definition of the civil law-term employee. The definition is therefore of fundamental significance. Because of the protective characteristics of the
Alpha-synuclein is a protein involved in several neurodegenerative diseases, such as Parkinson’s, where it has been observed to form amyloid fibrils or Lewy bodies. However, how or to what extent alpha-synuclein is involved is not known. I have in this thesis been conducting experiments in order to design an experimental model system to study how alpha-synuclein interacts with a cell membrane. Thi
"The Moon is not made of cheese!": A history of ideas thesis on Georg Borgström and the space research This thesis discusses and analysis Georg Borgström’s arguments against the space research program in the 1960s. It begins with his appearance in the Swedish radio on the 28 of August 1960 with the title “Mat eller månraketer” (“Food or moon rockets”). It then stretches throughout the 6
In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. However, there is still little known about the impact of the development of building structures and building content on the fire behaviour and room conditions. This report shows a clear view of how these d
This mastert hesis has been done as a joint project between the Department of Automatic Control in Lund and Volvo Technological Development in Gothenburg. The thesis treats methods to handle nonlinearities in a throttle unit. Theapproach has been to first design a linear controller based on the results from system identification, and then to develop an adaptive updating law estimating uncertain pa
The task was to write a program for plotter output on a ink jet plotter built at Inst. för Elmät, LTH. This plotter puts dots of ink on a paper fastened to a rotating drum and it must have, for every x-coordinate in its turn, the y-coordinates in rising order where it shall put a dot. 0
Serious games have been increasingly interesting to educators recently, but it is difficult to find good games that truly address the needs of young learners, especially in mathematics. Some games are either too simplistic or are not actual games. In the paper, an argument is made for the benefits of game-based learning (GBL) for instruction and assessment given what we know about Millenials and h
Problem The often informal new service development processes and less structured decision processes for strategic decisions about service portfolio of service companies, makes it especially interesting to investigate the prerequisites for, and develop a formal process for decision making about new service development and create the right decision quality in these decisions. The main problem become
Within the political science research it is common to examine the effects on the national parliaments caused by European integration. In this Bachelor Thesis the aim is instead to show what involvement of the national parliaments in the European Union implicates to the European integration process. The object of examination is the introduction of the parliaments as supervisors of draft legislativ
Our aim is to use clustering algorithms in order to compute support and resistance levels within an intra-day trading setting. To achieve this we use a tick data set from the EUR-USD exchange market during 2019 as a measure of market activity. Both the Gaussian Mixed Model (GMM) and an altered form of Kmeans clustering will be used as clustering methods where each method will be evaluated using a
In the context of continuous biodiversity loss connected to land-use changes and urban development, different methods such as biodiversity offsetting with the underlying aim of achieving “No Net Loss” (NNL) of biodiversity has been proposed. Compensation according to the mitigation hierarchy is one type of biodiversity offsetting which currently is being used in the municipality of Helsingborg, Sw
