1. Hur använder man x egentligen?
Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaperSammanfattning : The purpose of this thesis was to investigate whether students understanding of letter symbols in algebra has changed since Dietmar Küchemanns study in 1976, as well as to see whether teachers’ view on students understanding and their misconceptions correlate with the test results shown by the students. To be able to measure the students understanding, the same test that Küchemann used in 1976 was used on students aged 15/16 today (although on a much smaller scale), and the results were then analysed, and the students were categorised into different levels of understanding, based on the descriptions of the levels made by Küchemann in 1981.

2. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. LÄS MER
3. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER
4. Allt är politik : Dolda budskap i ett kungligt karolinskt porträtt
Kandidat-uppsats, Uppsala universitet/Konstvetenskapliga institutionenSammanfattning : In 1704 Hedvig Eleonora, the dowager queen of Sweden, commissioned a portrait of herself and her great-grandson, Karl Fredrik, the duke of Holstein-Gottorp, four years of age. The portrait by court portraitist David von Krafft is quite formal in style, and alludes to other royal portraits in a number of dynastic symbols and visual conventions although it is unusual in its composition and subject-matter.

5. Optimization of Physical Uplink Resource Allocation in 5G Cellular Network using Monte Carlo Tree Search
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Physical Uplink Control Channel (PUCCH), which is mainly used to transmit Uplink Control Information (UCI), is a key component to enable the 5G NR system. Compared to LTE, NR specifies a more flexible PUCCH structure to support various applications and use cases. LÄS MER
