  1. 21. Evaluating Donor-Funded ICT Projects : How Significant is Western-Centrism?

    University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Author : Zivile Necejauskaite; [2021]
    Keywords : ICT; development; project evaluation; impact; outcome; results;

    Abstract : Donor-funded economic and development assistance for various countries and regions has been steadily increasing in the last half-century. According to the World Bank, the funding amount provided by this organisation has increased more than 40 times from 4.6 billion USD to 166 billion USD in a 58-year span (World Bank, 2018). READ MORE

  3. 22. Insomnia and fear extinction : Review and analysis of the evolutionary emotional hypothesis

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Sofia Wachtmeister; [2021]
    Keywords : Sleep; insomnia; hyperarousal; fear conditioning; fear extinction; evolutionary-emotional hypothesis;

    Abstract : Insomnia is one of the most common health issues, with occasional symptoms affecting up to 50% of the general population. Lack of sleep is associated with many negative health effects. A new evolutionary hypothesis has been proposed to explain the mechanism behind insomnia symptoms. READ MORE

  4. 23. 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. 24. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    University essay from KTH/Betongbyggnad

    Author : Anton Frank; Andreas Fristedt; [2021]
    Keywords : Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Abstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  6. 25. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE
