  1. 21. Improving the Accuracy of 2D On-Road Object Detection Based on Deep Learning Techniques

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

    Author : Ying Yu; [2018]
    Keywords : ;

    Abstract : This paper focuses on improving the accuracy of detecting on-road objects, includingcars, trucks, pedestrians, and cyclists. To meet the requirements of theembedded vision system and maintain a high speed of detection in the advanceddriving assistance system (ADAS) domain, the neural network model is designedbased on single channel images as input from a monocular camera.

  3. 22. Influence of logging residues on MeHg accumulation in soil

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Axel Blomgren; [2018]
    Keywords : Mercury methylation; Forestry; Dissolved organic matter; Soil temperature; Soil water content;

    Abstract : Forestry has been found to increase the accumulation of methyl mercury (MeHg), a highly neurotoxic compound, in forest soils. However, little is known about how forestry influences catchment processes that governs the mercury (Hg) methylation process. READ MORE

    Abstract : Arsenik är ett mycket giftigt ämne som finns i berg, mark och grundvatten, och är känt för att orsaka allvarliga hälsoeffekter. Neurologiska skador hos människan inträffar vid koncentrationer så låga som 100 μg/L, medan 1–3 mg/kg kroppsvikt As är en dödlig dos. READ MORE

  5. 24. Spatial Variation of THg and MeHg Stream Concentrations and Its Relation to TOC

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Tranvik; [2017]
    Keywords : Mercury; organic matter; catchment characteristics; GIS; deforestation; Kvicksilver; organiskt material; avrinningsområdesfaktorer; GIS; skogsavverkning;

    Abstract : Mercury (Hg) which originates from global emissions to the atmosphere can deposit far away from the source. There is often a weak correlation between Hg deposition and concentrations in runoff, therefore catchment specific parameters might be of importance in controlling the amount of Hg ending up in watercourses and fish.
