1. 16. Statistical Analysis on Aerodynamics of Passenger Vehicles

   University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

   Author : Dingkang Peng; [2023]
   Keywords : statistics; aerodynamics; automotive engineering; causality; time series; cluster analysis;

   Abstract : This thesis aims to use statistical methods to analyze wind tunnel data generated in automotive aerodynamics testing to understand the properties of aerodynamic force and pressure in a vehicle's working environment. The data used for analysis are visualized, clustered and finally analyzed for Granger causality to see whether a causal link exists between different variables. READ MORE

3. 17. Towards Realistic Datasets forClassification of VPN Traffic : The Effects of Background Noise on Website Fingerprinting Attacks

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Author : Christoffer Sandquist; Jon-Erik Ersson; [2023]
   Keywords : Data collection; Website fingerprinting; dataset; traffic analysis; VPN; encrypted traffic; machine learning; deep learning; network measurements; twitch; Datainsamling; Profilering av hemsidor; dataset; trafikanalys; VPN; krypterad trafik; maskininlärning; djupinlärning; nätverksmätningar; twitch;

   Abstract : Virtual Private Networks (VPNs) is a booming business with significant margins once a solid user base has been established and big VPN providers are putting considerable amounts of money into marketing. However, there exists Website Fingerprinting (WF) attacks that are able to correctly predict which website a user is visiting based on web traffic even though it is going through a VPN tunnel.

4. 18. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

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

   Author : Ulrike Küst; [2023]
   Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

   Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

5. 19. Prototyping and manufacturing of air-controlled damper unit to improve cooling system operating efficiency for data centers

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Peter Nilsson; [2023]
   Keywords : data center; cooling; server; design; efficiency; model; design; holistic cooling; cooling system; air cooling; differential pressure; wind tunnel; CRAH; datacenter; luftkylning; modell; design; CRAH; kylning; tryck; vindtunnel; server;

   Abstract : More and more people are using the internet for data processing, transfer, and storage. With it comes a higher demand for computational power from data servers. Unsurprisingly, the data center industry is becoming an increasingly large industry that is important for people’s daily lives. READ MORE

6. 20. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Annachiara Nardone; [2023]
   Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

   Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE
