  1. 1. Investigating Gas Turbulence in Galactic Discs

    Master-uppsats, Lunds universitet/Astronomi

    Författare :Timmy Ejdetjärn; [2019]
    Nyckelord :galaxies; gas; turbulence; interstellar medium; star formation; feedback; gravitational instability; local; high redshift; Physics and Astronomy;

    Sammanfattning : The interstellar medium of both local and distant disc galaxies is observed to be supersonically turbulent and the turbulent motion of the gas is thought to be important for galaxy formation and evolution, particularly as a key ingredient for star formation. Consequently, this generates a striking relation between the star formation rate (SFR) and gas velocity dispersion ($\sigma_{\rm g}$; a measurement on the level of turbulence). LÄS MER

  2. 2. Automated Key Rotations In a Continuous Deployment Pipeline


    Författare :Jim Rylander; Jacob Moberg; [2018]
    Nyckelord :Security; Continuous Deployment; Key rotation; Key management;

    Sammanfattning : Background. To the best of our knowledge, there is no related work that brings up key management in Continuous Deployment. Most of the previous research within the area handles challenges and how to apply to continuous methods. Objectives. LÄS MER

  3. 3. Evaluation of Data Augmentation of MR Images for Deep Learning

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Erik Andersson; Robin Berglund; [2018]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Data augmentation is a process to create new artificial data by altering the available data set. It has by many been considered a key factor for increasing robustness and performance of image classification tasks using deep learning methods, such as the convolutional neural network. LÄS MER

  4. 4. Human Resource Management Practices Contributing to Competency Enhancement of Project Managers and Team Members in Project-Based Organizations:The Case of IT Industry in France

    Master-uppsats, Umeå universitet/Företagsekonomi; Umeå universitet/Företagsekonomi

    Författare :Boris Fionov; Vusal Mustafayev; [2018]
    Nyckelord :Project Management; Human Resource Management; Competence Management; Human Resource Practices;

    Sammanfattning : In the contemporary business world firms are being transformed into project-based organisations when majority of functions are performed through projects while administrative support is provided by permanent organisational structures. Moreover, variety of industries develop characteristics of Project-Based organizations which implies that HR practices need to be adjusted to help project employees to acquire necessary skills to adapt technology and help company embrace changes in business environment.

  5. 5. Whole farm technical efficiency : the case of Ethiopian smallholders: time-variant stochastic frontier model

    Master-uppsats, SLU/Dept. of Economics

    Författare :Astewale Bimr Melaku; [2018]
    Nyckelord :smallholder farmers; technical efficiency; time-variant; Ethiopia;

    Sammanfattning : This study uses a time-varying random-effects stochastic frontier model to estimate level of whole farm technical efficiency using 3,465 observations of sample smallholder farmers located in Tigray, Amhara, Oromia, and Southern Nation and Nationalities (SNNP) regions of Ethiopia. A baseline econometric analysis has been done by employing Corrected Ordinary Least Square (COLS) and cross-section data models prior to the panel data model analysis as a robustness check. LÄS MER
