  2. 1. An inquiry into the nature and causes of digital platforms

    Author : Ted Saarikko; Katrin Jonsson; Jonny Holmström; Panos Constantinides; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital platform; platform strategy; platform development; stability; affordance theory; qualitative study; data- och systemvetenskap; computer and systems sciences;

    Abstract : While the shape and nature of platforms varies across different instances, they pursue common ambitions such as reduction of risk, complexity, or transaction costs. Although initially theorised in industrial contexts, subsequent theorising regarding platform development, platform ecosystems, and platform strategy has drawn upon studies of high-tech industries in general and IT-based platforms in particular.

  4. 2. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation

    Author : Sulena Pradhan; Inger Odnevall Wallinder; Jonas Hedberg; Eva Blomberg; Emma Strömberg; Kerstin Forsberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; freshwater; di-hydroxybenzoic acid; humic acid; copper; aluminium; manganese; dissolution; agglomeration; stability; complexation; Kemi; Chemistry;

    Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.

  5. 3. Legged locomotion : Balance, control and tools - from equation to action

    Author : Christian Ridderström; KTH; []
    Keywords : legged locomotion; control; balance; legged machines; legged robots; walking robots; walking machines; compliance; platform stability;

    Abstract : This thesis is about control and balance stability of leggedlocomotion. It also presents a combination of tools that makesit easier to design controllers for large and complicated robotsystems. The thesis is divided into four parts. READ MORE

  6. 4. Enabling a Robot for Underwater Surface Cleaning

    Author : Houssam Albitar; Amy Loutfi; Anani Ananiev; Mikael Ekström; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; underwater robot; underwater cleaning; biofouling; adhesion; locomotion; stability; Reglerteknik; Automatic Control;

    Abstract : Biofouling build-up on submerged structures such as ships, petroleum and gas storage tanks, electric power plants, bridges, oil rigs etc. is a major problem that affects the surface material of the structure, the eventual hydrodynamic quality of the surface and in some cases the efficacy of cooling systems.

  7. 5. Towards a versatile gas sensing platform with epitaxial graphene

    Author : Marius Rodner; Jens Eriksson; Kajsa Uvdal; Roland Pohle; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The work presented in this thesis focuses on how to utilize epitaxially grown graphene on SiC as a basis for ultra-sensitive gas sensor. Several approaches have been tested and evaluated to increase the sensitivity, selectivity, speed of response and stability and of the graphene based gas sensors with a focus on air quality monitoring applications.
