1. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE

2. Liminal life at railway stations: An ethnographic investigation of commuters' everyday rituals
University essay from Lunds universitet/Avdelningen för etnologiAbstract : Building functional and effective railway station infrastructures has become a strategy to encourage sustainable mobility. Addressing on commuters, this thesis aims to investigate how station infrastructures frame commuters' commuting experience. READ MORE

3. Soil-Structure Interaction Analysis of Portal Frame Railway Bridges : Numerical Analysis of Two Case Study Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : This thesis concerns dynamic Soil-Structure Interaction (SSI) analysis of portal framerailway bridges. Dynamic problems are common for bridges used for high speedrailway traffic. The passing trains induce harmonic loads on the bridges causingvibration amplitudes that may cause damage to the bridge structures and userdiscomfort. READ MORE

4. Using Bidirectional Encoder Representations from Transformers for Conversational Machine Comprehension
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Bidirectional Encoder Representations from Transformers (BERT) is a recently proposed language representation model, designed to pre-train deep bidirectional representations, with the goal of extracting context-sensitive features from an input text [1]. One of the challenging problems in the field of Natural Language Processing is Conversational Machine Comprehension (CMC). READ MORE

5. CFD ANALYSIS OF PRESSURE WAVES AND LOADS ON NON-TIGHT TRAINS PASSING TUNNELS
University essay from KTH/MekanikAbstract : Computing the loads for a train passing a tunnel requires to predict both the external and the internal pressure variations in time, both of which are strong and quick for a non-pressure tight train. The key achievement of this work has been the development of 3D CFD Star-CCM+ overset mesh simulations capable of simulating the single train tunnel entry and tunnel passage as well as the two trains crossing inside the tunnel.
