    Abstract : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  5. 3. Design, testing and analysis of journal bearings for construction equipment

    Author : Henrik Strand; Sören Andersson; Arto Lehtovaara; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact Mechanics; Finite Element; Grease; Journal Bearing; Lubrication; Replica Technique; Test Apparatus; Tribology; Wear; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Abstract : Grease-lubricated journal bearings present a common challenge for construction equipment manufacturers in the world. The common design methodology is based on empirical data and has worked very well historically because the market and governments have accepted that bearings in construction equipment need frequent lubrication and exchange of worn parts.

  6. 4. The effect of scale on the morphology, mechanics and transmissivity of single rock fractures

    Author : Nader Fardin; KTH; []
    Keywords : Anisotropy; Aperture; Asperity degradation; Contact area; Finite Element Method FEM ; Flow analysis; Fractals; Fracture morphology; Heterogeneity; Stress-deformation; Surface roughness; Roughness-Length method; Scale dependency; Stationarity; Transm;

    Abstract : This thesis investigates the effect of scale on themorphology, mechanics and transmissivity of single rockfractures using both laboratory and in-situ experiments, aswell as numerical simulations. Using a laboratory 3D laserscanner, the surface topography of a large silicon-rubberfracture replica of size 1m x 1m, as well as the topography ofboth surfaces of several high-strength concrete fracturereplicas varying in size from 50mmx50mm to 200mm x 200mm, werescanned.

  7. 5. Interface Defeat and Penetration: Two Modes of Interaction between Metallic Projectiles and Ceramic Targets

    Author : Patrik Lundberg; Bengt Lundberg; Charles E. Anderson Jr.; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; projectile; target; impact; interface defeat; penetration; tungsten; ceramic; replica scaling; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Ceramics constitute an important group of low-density armour materials. Their high intrinsic strength makes it possible to design ceramic armour systems capable of defeating projectiles directly on the ceramic surface. READ MORE
