  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  3. 2. Cooperation be damned : A study on water relations in The Nile River Basin

    University essay from Stockholms universitet/Institutionen för ekonomisk historia och internationella relationer

    Author : Gustav Alfvin; [2022]
    Keywords : Human Security; Water Wars; Egypt; Ethiopia; Process Tracing; GERD;

    Abstract : The Grand Ethiopian Renaissance Dam built on the Nile has sparked conflicts for over twelve years now since it was first announced in 2009. But in 2020 when Ethiopia finally started to fill this behemoth of a dam hostilities ramped up between Egypt and Ethiopia. READ MORE

  4. 3. Study of the Resistive Switching Mechanism in Novel Ultra-thin Organic-inorganic Dielectric-based RRAM through Electrical Observations

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

    Author : Alba Maria Martinez Garcia; [2021]
    Keywords : Resistive random-access memory RRAM ; flexible electronics; organic-inorganic hybrid dielectric; dual-mode conducting filament; electrical programming; Resistivt slumpmässigt åtkomstminne RRAM ; flexibel elektronik; organisk-oorganisk hybrid dielektrikum; dubbelt läge ledande glödtråd; elektrisk programmering;

    Abstract : The promising role resistive random-access memory (RRAM) plays in the imminent reality of wearable electronics calls for a new, updated physical model of their operating mechanism. Their high applicability as the next-generation flexible non-volatile memory (NVM) devices has promoted the recent emergence of a novel ultra-thin (< 5nm) organic/inorganic hybrid dielectric RRAM.

  5. 4. Nanoscale electrical properties of heterojunction interfaces for solar cells : modeling and experiments

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

    Author : Martin Eriksson; [2018]
    Keywords : solar cell; heterojunction; ZnO; Cu2O; Comsol; atomic force microscopy; I-V characteristics;

    Abstract :   A numerical model have been developed in order to describe and achieve deeper understanding of experimentally obtained I-V curves from Cu2O/ZnO p-n heterojunctions for potential use as future solar cell material. The model was created using the simulation software COMSOL Multiphysics® and their semiconductor module. READ MORE

  6. 5. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF

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

    Author : Sebastian Pfaff; [2017]
    Keywords : plif; laser diagnostics; catalysis; carbon monoxide; carbon dioxide; palladium; planar laser induced fluorescence; Physics and Astronomy;

    Abstract : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. READ MORE
