1. 1. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nicoline Krogh Hemme; [2020]
   Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

   Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE

3. 2. UE Performance in a 5G Multi-connectivity UDN City Scenario

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : José Perdomo; [2019]
   Keywords : ;

   Abstract : Multi-connectivity and network densification are two solutions intended to enhance user throughput and reliability. These solutions are critical since 5G NR uses a wide range of frequency bands, which exhibit different varying radio coverage characteristics. READ MORE

4. 3. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Viktor Eriksson; [2019]
   Keywords : Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

   Abstract : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.

5. 4. Performance of jet subtraction in pPb and PbPb collisions, without collectivity

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Sebastian Grabowski; [2018]
   Keywords : heavy ion: scattering; Angantyr; underlying event; subtraction; jet: quenching; non-collectivity; stacking; jet: correlation; non-colliective; background; Physics and Astronomy;

   Abstract : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.

6. 5. Understanding water film assisted CO intercalation underneath Ir(111) supported graphene

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Jonathan Peterson; [2017]
   Keywords : intercalation; graphene; scanning tunneling microscopy; Physics and Astronomy;

   Abstract : The aim of this project is to use scanning tunneling microscopy (STM) to investigate how a super-dense phase of OH and H2O, intercalated between graphene flakes and their Ir(111) substrate, facilitates intercalation of CO underneath the graphene flakes at ultra high vacuum (UHV) conditions. The structure and growth of pristine graphene flakes on Ir(111) is discussed and the formation of dense islands of OH and H2O formed below the graphene flakes upon exposure to O2 and H2, is studied using STM.
