  1. 1. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

    Author : Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

    Abstract : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

  2. 2. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    Author : Liang Liu; Pärt Peterson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Abstract : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. READ MORE

  3. 3. Livelihood Implications of Large-Scale Land Concessions in Mozambique : A case of family farmers’ endurance

    Author : Juliana Porsani; Kari Lehtilä; Rickard Lalander; Lowe Börjeson; Randi Kaarhus; Södertörns högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Large-scale land acquisitions; land concessions; land grabs; livelihoods; family farmers; peasants; gender; community consultations; popular deliberation; cultural ecosystem services; Mozambique; Lower Limpopo Valley; Environmental Studies; Miljövetenskapliga studier;

    Abstract : This thesis examines the process and the implications of large-scale land acquisitions (LSLAs) for local livelihoods, especially the livelihoods of those who make a living from farming. These individuals were historically known as peasants and are now more commonly referred to as smallholders, small-scale farmers or family farmers. READ MORE

  4. 4. Compensating for Unreliable Communication Links in Networked Control Systems

    Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

    Abstract : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. READ MORE

  5. 5. Dryer Section Control in Paper Machines During Web Breaks

    Author : Jenny Ekvall; Mittuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dryer Section; Web breaks; Paper machine; steam pressure control; Physical modeling; Automatic control; Reglerteknik;

    Abstract : Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. READ MORE
