  1. 1. Air quality prediction in metropolitan areas using deep learning methods

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Augustin Ionut Ionascu; [2023]
    Keywords : air quality; forecasting; time-series; univariate; multivariate; multi-step; Attention; Transformer;

    Abstract : The rapid growth of the world's urban population shows that people are increasingly moving to cities. In recent decades, the frequent occurrence of smog caused by increasing industrialization has brought environmental pollution to record highs. READ MORE

  3. 2. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

    University essay from Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

    Author : Björn Landeke-Wilsmark; [2022]
    Keywords : Physics and Astronomy;

    Abstract : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.

  4. 3. Microbial ecosystem analysis of biochar-enriched soil in Kenya using microfluidic soil models

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Erik Karlsson; [2022]
    Keywords : Soil microbial ecosystem analysis; Microbe abundance; Microbe foraging; Biochar; Agriculture; Microfluidics; In-situ visualization; Kenya; SoilChip; Soil model; Minor Field Study; Technology and Engineering;

    Abstract : Healthy soil is rich in diverse microbial life, and a healthy microbial ecosystem is crucial for any well-functioning agriculture. Soil microbes are essential for organic decomposition and nutrient recycling in the soil, which make nutrients available for agricultural crops. READ MORE

  5. 4. Colombia’s Socio-Economic Stratification System : An urbanisation policy that causes intergroup conflict?

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Emil Pålsson; [2020]
    Keywords : Urbanisation; Segregation; Inequality; Social Identity; Intergroup Conflict; Peaceful Coexistence; Bogotá; Colombia; SDG 10;

    Abstract : Rapid urbanisation is a global phenomenon on the rise. If managed poorly by the cities affected, it may lead to, e.g. segregation, air pollution and civil unrest. READ MORE

  6. 5. Fractionation of NOM in water from the treatment process at Ringsjöverket

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stina Karlsson; [2018]
    Keywords : water engineering; environmental engineering; avloppsteknik; Technology and Engineering;

    Abstract : During the last decades, increased concentrations of natural organic matter (NOM) and colour of surface waters have been reported from northern Europe and North America. Since surface waters are widely used for drinking water production this development has been problematic for drinking water producers. READ MORE
