1. 1. Parabolic equation models simulating LoS MIMO conditions

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Zarafshan Carneil; [2023]
   Keywords : MIMO; channel capacity; phase difference; MIMO phase;

   Abstract : This thesis explores and develops a simulation model for Line of Sight(LoS) Multiple-Input Multiple-Output (MIMO) systems in complex environments. The focus will be on implementing a 2 × 2-MIMO system in order to study phase differences of the received signals. READ MORE

3. 2. Magnetization dynamics in bistable systems

   University essay from Uppsala universitet/Materialfysik

   Author : Sven Backlund; [2023]
   Keywords : magnetism; magneto-optics; magnetization dynamics;

   Abstract : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. READ MORE

4. 3. Estimation of Parabolic Microwave Antenna Movements Using Sensor Fusion

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Nikhil Challa; [2023]
   Keywords : Technology and Engineering;

   Abstract : Wireless communication has seamlessly integrated itself into our daily lives, with Ericsson pioneering the development of comprehensive mobile ecosystems. As the demand for data traffic continues to surge, the enhancement of both cellular radio systems and backhaul infrastructure remains paramount. READ MORE

5. 4. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Vikramjeet Das; [2023]
   Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

6. 5. On Geometric Number

   University essay from Uppsala universitet/Analys och partiella differentialekvationer

   Author : Petter Gunnarsson; [2023]
   Keywords : clifford algebra; hypercomplex number; octonion;

   Abstract : This is an overview of geometric algebras in dimensions 0-4 from the perspective of the concept of number itself. It is developed from a historic viewpoint and investigates and develops a pedagogic approach emphasizing the geometric aspects of the subject. READ MORE
