  1. 36. Functional Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Brice Metzinger; [2022]
    Keywords : ;

    Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, an orbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulation of the off-design operation of the cryogenic engine of Nyx. READ MORE

  3. 37. Video-Based Estimation of Driver Sleepiness Using Machine Learning

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Simon Knutsson; [2022]
    Keywords : Driver sleepiness; drowsiness; classification; estimation; machine learning;

    Abstract : Approximately 1.35 million people die each year in car accidents and it is the most common cause of death for people aged 5-29. Because of this it is of large interest to be able to detect when a driver enters a sleepy state and to be able to alert the driver. READ MORE

  4. 38. Aerodynamic studies of the flutter behavior of a compressor jet engine : Establishment of 1D criteria for the appearance of flutter within low pressure compressors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lucas Citoleux; [2022]
    Keywords : ;

    Abstract : Turbojet compressors are subject to numerous vibration phenomena that limit their good operability. Among these different phenomena, flutter is a major concern during the study and design phase. This aeroelastic instability can have an impact on the correct operation of the compressor. READ MORE

  5. 39. C/O+ charge transfer & the Olson-Demkov model

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Kristoffer Bengtsson; [2021]
    Keywords : Astronomy; Charge transfer; rate coefficient; Carbon; Oxygen; energy defect; spectral modelling; supernovae;

    Abstract : Charge transfer reactions and their rates play a key role in correctly estimating element abundances in astrophysical objects such as supernovae. The reaction $C + O^+ \rightarrow C^+ + O(^1D) + \Delta E$ has been shown to be of significance when estimating oxygen abundances through model spectrum evaluations, and the relative rate of this reaction can under certain circumstances completely dictate the neutralization rate of oxygen ions.

  6. 40. In the search for novel antirheumatics: Re-discovery of a secoiridoid aglycone in Chinese ethnomedicine Radix Gentiana macrophylla Pall.

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Ali Zakaria Abdella Osman; [2021]
    Keywords : rheumatoid arthritis; gentianaceae; qinjiao; gentiana macrophylla pall.; secoiridoid; NPNPD;

    Abstract : Rheumatoid arthritis (RA) is a chronic, inflammatory, autoimmune disease that although systemic, mainly affects the synovium of the joints. Currently, remission is the goal of RA treatment. Research efforts are however targeted towards finding a cure. Radix Gentiana macrophylla Pall. READ MORE
