  1. 1. Implementation of PID control using Arduino microcontrollers for glucose measurements and micro incubator applications

    University essay from Uppsala universitet/Fasta tillståndets elektronik; Uppsala universitet/Fasta tillståndets elektronik; Uppsala universitet/Fasta tillståndets elektronik

    Author : Hugo Andersson; Viktor Mattsson; Aleksandar Senek; [2015]
    Keywords : ;

    Abstract : The task is to build a low-cost thermostat and design necessary elements to perform a study on water mixed glucose-impedance at different temperatures and cell growth in a temperature-controlled incubator housing a magnetic field of up to 3 mT. The incubator was designed in solidworks and made to fit petri dishes of two relevant sizes and necessary wiring. READ MORE

  2. 2. Evaluation of "GIN method" at Two fans of City banan project in Stockholm

    University essay from KTH/Jord- och bergmekanik

    Author : Mehran Neshati Sani; [2015]
    Keywords : grouting; GIN method; cement; jacking; penetration; pressure; volume intake;

    Abstract : An underground installation with too much inflow can lead to dangerous consequences for around environment, therefore a well-sealed construction results in appropriate inflows. To mitigate movement of ground water table in underground constructions, it is necessary to seal the rock mass by grout injection. READ MORE

  3. 3. Design and Implementation of a Glider Control System

    University essay from KTH/Optimeringslära och systemteori

    Author : Hannah Lindberg; [2015]
    Keywords : ROBEX; MOTH; glider; buoyancy; OBC; actuators; pitch; deflection; AHRS;

    Abstract : ROBEX is a unique research project combining Airbus Defence and Space’s robotics expertise with deep-sea exploration technology to discover more about the most extreme environments environments known to man. As a part of this project, a deep-sea glider called MOTH, is under development with the objective to determine whether gliders can be used as a platform for bathymetric and electromagnetic soundings of the seafloor as well as for new water column research.

  4. 4. Decomposition of leaf litter in headwater streams. : Effects of changes in the environment and contribution of microbial and shredder activity on litter decomposition.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Johan Lidman; [2015]
    Keywords : Leaf-litter decomposition; headwaters; microbial decomposition; shredders; ecosystem adaptation;

    Abstract : Headwaters, which are the most common stream order in the landscape, are mostly dependent on energy produced in the terrestrial system, largely consisting of leaf litter from riparian vegetation. The aim of this study was to investigate the decomposition in headwaters of leaf litter from three native (alder, birch, spruce) and one non-native (lodgepole pine) species and how decomposition responds to changes in the environment.

  5. 5. Monitoring and managing Chromolaena odorata in a South African savanna reserve : Evaluating the efficacy of current control programs in response to ecological factors and management protocols

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : L. Alexander Dew; [2015]
    Keywords : invasive; management; monitoring; savanna; Chromolaena odorata;

    Abstract : Biological invasions have increased dramatically in the past centuries and are one of the greatest threats to biodiversity today. Invasions occur when organisms are introduced at a location to which they are non-native, and they reproduce and spread, causing damage to the environment. READ MORE
