  1. 1. Techno-economic analysis and simulation of low temperature district heating networks

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ilia Iarkov; [2023]
    Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

  2. 2. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tómas Halldórsson Alexander; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  3. 3. Study and optimization of a hexacopter's composite structure

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Helena Delmotte; [2023]
    Keywords : Lightweight structure; Drone; Structural optimization; FEA; Lättviktsstruktur; Drönare; Strukturell optimering; FEA;

    Abstract : Nowadays, the forestry industry still uses heavy machinery damaging both the forest and the soil. The start-up AirForestry is currently developing a sustainable way to thin and harvest trees. With their 6.2m wide electric drone carrying a harvesting tool, they can reach, thin, cut and carry trees without the need for access roads. READ MORE

  4. 4. Growing on the roof : But in what? Examing substrates/growing media for rooftop farming

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Mikael Brocki; [2023]
    Keywords : urban rooftop agriculture; URTA; green roof; substrate; growing medium; organic matter; compost; vegetable; crop; yield; lettuce; tomato; pore; pore-size distribution;

    Abstract : Urban Rooftop Agriculture (URTA) is a novel field within urban vegetable production, which can help create access to local food in a rapidly urbanizing world. For these systems to succeed, it is vital to implement a proper choice of substrate/growing medium (SGM). READ MORE

  5. 5. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

    University essay from Uppsala universitet/Signaler och system

    Author : Anthony Gundstedt; [2023]
    Keywords : drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

    Abstract : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. READ MORE
