  1. 1. Data-driven Dynamic Baseline Calibration Method for Gas Sensors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Cheng Yang; [2021]
    Keywords : CO2 gas sensing; drift; dynamic baseline calibration; time series analysis; data-driven modeling; clustering; classification; CO2 gasavkänning; drift; dynamisk baslinjekalibrering; tidsserieanalys; datadriven modellering; kluster; klassificering;

    Abstract : Automatic Baseline Correction is the state-of-the-art calibration method of non-dispersive infrared CO2 sensing, which is the standard CO2 gas monitoring method. In this thesis, we improve it by introducing the dynamic baseline based on environmental data. READ MORE

  3. 2. Characterization of Silicon Waveguides For Non-Dispersive Infrared Gas Sensors

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sarah Zayouna; [2020]
    Keywords : ;

    Abstract : Carbon dioxide is an important gas for life on Earth. But as human activities have been expanding throughout modern history, the CO2 concentration in the atmosphere is increasing. High concentrations of carbon dioxide can lead to various consequences, such as climate change and poor air quality both indoors and outdoors. READ MORE

  4. 3. Object-Based Classification of Vegetation at Stordalen Mire near Abisko by using High-Resolution Aerial Imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Marco Giljum; [2014]
    Keywords : Physical Geography and Ecosystem Analysis; Object-Based Image Analysis; OBIA; Vegetation Classification; Permafrost; Arctic Peatland; Remote Sensing; Aerial Photography; Environmental Monitoring; Landscape Analysis; Earth and Environmental Sciences;

    Abstract : The focus of this work is to investigate and apply the remote sensing method of object-based image analysis (OBIA) for vegetation classification of a permafrost underlain peatland in sub-arctic Sweden, by using aerial imagery of high resolution. Since the northern landscapes are an important source of naturally stored CH4 and CO2, their contribution to the global carbon cycle is a focus in research about climate change and the global methane exchange.

  5. 4. Atomic Scale Design of Graphene based Gas Sensors

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Nandini Patra; [2014]
    Keywords : ;

    Abstract : In this project work, we have performed Density Functional Theory (DFT) calculations to study the gas (CO, NO and CO2) sensing mechanism of pure and doped (B, N and B-N) graphenesurfaces. Generalized gradient approximation (GGA-PBE) within projector-augmented  wave (PAW) methodology were adopted to investigate the electronic properties  of such materials. READ MORE
