1. 1. Implementation of Level of Development for BIM Collaboration in Timber Building Subsystems Design: A Case Study of I-Joist Construction Elements

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

   Author : Isabell Gustafsson; [2024]
   Keywords : BIM; I-Joist; LOD; Level of Development; Timber Building Subsystems;

   Abstract : Due to time, cost, and environmental challenges, wood has become a more common building material even for more complex buildings. Implementing the concept of Level of Development (LOD) on timber structures could provide a tool for BIM collaboration that may save cost and time, and in the early stages mediate wood as an available building material.

3. 2. Drop-weight impact tests on reinforced concrete beams

   University essay from KTH/Betongbyggnad

   Author : John Abdalnour; Milad Saliba; [2023]
   Keywords : ;

   Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

4. 3. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

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

   Author : Therese Bäckström; [2023]
   Keywords : Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

   Abstract : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. READ MORE

5. 4. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

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

   Author : Saga Westerberg; [2023]
   Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

   Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

6. 5. Investigation of Ion Extraction Anomalies at TwinEBIS

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Niek van Woudenberg; [2023]
   Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

   Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE
