  1. 1. Language Theoretic Properties of Graph Extension Languages : An Investigation of Graph Extension Grammars with Context Matching and Logic

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Yannick Stade; [2022]
    Keywords : graph language; formal language; theoretical computer science;

    Abstract : Graph extension grammars provide a way to define graph languages. They consist of a regular tree grammar and an algebra. The regular tree grammar generates trees, so-called derivation trees. Those are evaluated by the algebra into a set of graphs. READ MORE

  2. 2. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ann-Kathrin Wild; [2022]
    Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

  3. 3. Utvärdering av metod för att morfologiskt särskilja björkarterna Betula pendula och Betula pubescens

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Pontus Nykvist; [2022]
    Keywords : björk; morfologi; artbestämning; fällningsmetoden; Silver birch; Downy birch;

    Abstract : Birch is the third most common tree species in Sweden and has previously been seen as a weed in the forests. In the last 20 years, birch has had a clearly increasing trend in Swedens growing timber stock, but there are still many knowledge gaps regarding management, regeneration, processing, and its impact on the environment.

  4. 4. Ekologiska restaureringsåtgärders påverkan på unga trädplantor : bränning och luckhuggnings effekt på unga trädplantor

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Atle Brevik Svensson; Ludwig Olofsson; [2022]
    Keywords : biodiversitet; bränning; luckhuggning; ekologisk restaurering; skogsbruk; störning; succession; trädslagsblandning; unga trädplantor;

    Abstract : Biodiversity is fundamental for a stable and functional ecosystem. However, studies have shown that biodiversity in Sweden is slowly declining due to modern forestry. This needs to be changed and ecological restoration can prevent further biodiversity loss. READ MORE

  5. 5. FPGA Implementation of Feature Matching in ORB-SLAM2

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hannah Lindström; [2022]
    Keywords : Autonomous navigation; SLAM; Feature matching; FPGA; ORB; Heterogeneous binary tree; Technology and Engineering;

    Abstract : Simultaneous Localization And Mapping (SLAM) is an important component in solving the problem of autonomous navigation — allowing machines such as selfdriving cars and mobile robots to find their way in the world without human instruction. Though there is a steadily growing body of literature in the field of SLAM, far fewer works currently address using hardware acceleration to speed up this computationally heavy task. READ MORE
