  1. 1. Quality Assurance Processes within the field of PME : An Analysis from the Implementational Perspective

    University essay from Försvarshögskolan

    Author : Markus Rönnlund; [2022]
    Keywords : Quality Assurance; Professional Military Education; PME; Implementation; Fidelity; Core Implementation Components Model; Organizational Change; Quality Management;

    Abstract : Defensive cooperation between member states is considered an integral part on the EU agenda. Yet, despite the evident demand for integrative defensive mechanisms at the EU level, there appears to be no consensus on how military personnel should be trained. READ MORE

  3. 2. Evaluation of Arrival Sequencing at Arlanda Airport

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Lucie Smetanová; [2020]
    Keywords : Key performance indicators; arrival sequencing; aircraft spacing; sequence pressure;

    Abstract : This work presents an analysis of arrival sequencing at Stockholm Arlanda airport. Thesequencing of arrivals is very important part of air traffic control management and assuressafe space and time distancing of arriving aircraft. In this work we use historical flight datafrom Opensky Network database. READ MORE

  4. 3. Geographical and functional airspace design in Stockholm TMA

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Isabella Madsen; Adam Olsson; [2017]
    Keywords : ;

    Abstract : Flygtrafiken i Europa ökar ständigt och luftrumskapaciteten måste förbättras för att kunna klara framtidens krav. Ett av de områden som behöver utvecklas är de luftrum som omsluter sammanstrålningen av flygvägar i närheten av en flygplats: terminalområden (TMA:n). READ MORE

  5. 4. ATC complexity measures: Formulas measuring workload and complexity at Stockholm TMA

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Amina Dervic; Alexander Rank; [2015]
    Keywords : Air traffic control; workload; complexity; LFV; ATC; flygledare; flygledning; Luftfartsverket; regression; MAP; Dynamic Density; DD;

    Abstract : Workload and complexity measures are, as of today, often imprecise and subjective. Currently, two commonly used workload and complexity measuring formulas are Monitor Alert Parameter and the “Bars”, both using the same measurement variables; amount of aircraft and time. This study creates formulas for quantifying ATC complexity. READ MORE

  6. 5. Quantum Chemical Feasibility Study of Methylamines as Nitrogen Precursors in Chemical Vapor Deposition

    University essay from Linköpings universitet/Kemi

    Author : Karl Rönnby; [2015]
    Keywords : Quantum Chemistry; Computational Chemistry; Density Functional Theory DFT ; B3LYP; Gaussian 4 G4 ; Chemical Vapor Deposition CVD ; Gallium Nitride GaN ; Aluminum Nitride AlN ; Ammonia NH3 ; Methylamine NH2CH3 ; Dimethylamine NH CH3 2 ; Trimethylamine NH CH3 3 ; Trimethylaluminum TMA ; Trimethylgallium TMG ; Decomposition; Adsorption;

    Abstract : The possibility of using methylamines instead of ammonia as a nitrogen precursor for the CVD of nitrides is studied using quantum chemical computations of reaction energies: reaction electronic energy (Δ𝑟𝐸𝑒𝑙𝑒𝑐) reaction enthalpy (Δ𝑟𝐻) and reaction free energy (Δ𝑟𝐺). The reaction energies were calculated for three types of reactions: Uni- and bimolecular decomposition to more reactive nitrogen species, adduct forming with trimethylgallium (TMG) and trimethylaluminum (TMA) followed by a release of methane or ethane and surface adsorption to gallium nitride for both the unreacted ammonia or methylamines or the decomposition products.
