  1. 1. Enterprise Modeling As a Competitive Advantage

    University essay from Uppsala universitet/Företagsekonomiska institutionen; Uppsala universitet/Företagsekonomiska institutionen

    Author : Bahram Nouraei; Angela Filipa Duarte Ferreira; [2020]
    Keywords : Enterprise Modeling; Enterprise Architecture; Change Management; Business Analysis; Competitive Advantage; Agile Management; Knowledge Integration; Corporate Agility; Entrepreneurship; Verksamhetsmodellering; Verksamhetsarkitektur; Förändringsledning; Affärsanalys; Konkurrensfördelar; Agil Management; Kunskapsintegration; Entreprenörskap;

    Abstract : This paper investigates the contribution of enterprise modeling to the emergence and sustainability of the firm’s competitive advantage using the theoretical model developed by Chandra S. Mishra (2017). Agility, alertness, knowledge integration and business model mechanisms have been identified as the main sources of competitive advantage. READ MORE

  2. 2. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jonathan Barassa; Rickard Nordlöf; [2020]
    Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

  3. 3. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE

  4. 4. Ionospheric Models for GNSS Measurements

    University essay from KTH/Fastigheter och byggande; KTH/Fastigheter och byggande

    Author : Carolina Offenbacher; Ellen Thornström; [2020]
    Keywords : GNSS; ROTI; TEC; ionospheric turbulence; GNSS; ROT; TEC;

    Abstract : There is an increasing demand for higher precision when using Global Navigation Satellite Systems, GNSS, for positioning. The measurement uncertainty depends on multiple factors and one of them is the ionosphere. READ MORE

  5. 5. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aljaz Janic; [2020]
    Keywords : Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Abstract : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. READ MORE
