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. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

   University essay from KTH/Matematik (Avd.)

   Author : Bill Claesson; [2023]
   Keywords : ;

   Abstract : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. READ MORE

4. 3. Investigation of soliton equations with integral operators and their dynamics

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Ruben Vikars Hall; Carl Svennerstedt; [2023]
   Keywords : Soliton; Calogero-Moser-Sutherland system; Lax pair; Hilbert transform; Szegö projection; Benjamin-Ono equation; Non-chiral Intermediate long-wave equation; Szegö equation;

   Abstract : We present Lax pairs and functions called Lax functions corresponding to Calogero- Moser-Sutherland (CMS) systems. We present the Benjamin-Ono (BO) equation and a pole ansatz to the BO equation, constructed from a specific type of Lax function called a special Lax function corresponding to Rational and Trigonometric CMS systems.

5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lukas Jonasson; [2023]
   Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

   Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

6. 5. Ocean rogue wave analysis for the development of safer navigation systems. : A Thesis submitted to the University of Gävle for the degree of Bachelor of Mathematics

   University essay from Högskolan i Gävle/Matematik

   Author : Sergio Manzetti; [2023]
   Keywords : ;

   Abstract : Rogue waves are unexpectedly high waves of 2.5X the significant wave height and which occur in nearly all phases of nature, from  oceans, to fiber-optic cables and atmospheric air-masses. In the ocean, rogue waves pose a significant danger to shipping and fishing vessels and have been found to reach 27. READ MORE
