1. Warm dark matter simulations and 21cm astronomy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The recent boom in 21cm astronomy has piqued the interest of many, especially cosmologists realizing its applications in their field. This study aims to determine if 21cm astronomy is a good tool for testing the validity of keV WDM models, as well as creating a code capable of simulating keV WDM models from an existing CDM code.

2. Self-consistent dielectric formalism scheme for the paramagnetic electron gas under warm dense matter conditions
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The present thesis aims to further a somewhat unexplored area of Warm Dense Matter (WDM) physics through the use of tools developed within the dielectric formalism. WDM is an exotic form of matter with densities close to the solid state and temperatures of several eV. LÄS MER
3. Analysis of the performance of Hybrid TWDM Passive OpticalNetworks (NG-PON2)
Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : In this study, a review of research literature has been carried out to investigate Hybrid Time and wavelength Division Multiplexing techniques with respect to reach, split ratio, and speed of the network. This was done to overcome challenges presented by Passive Optical Networks, such as the reach and the high split ratio. LÄS MER
4. An evaluation of deterministic prediction of ocean waves using pressure data to assist a Wave Energy Converter
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Currently, existing devices for extracting electrical power from ocean waves all suffer from problems with low efficiency due to a lack of information about the incoming waves in advance. The complex dynamic nonlinear characteristics of the ocean make the prediction of these incoming waves a great challenge. LÄS MER
5. Hardware-Efficient WDM/SDM Network : Smart Resource Allocation with SDN Controller
Master-uppsats, KTH/Kommunikationssystem, CoSSammanfattning : Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. LÄS MER
