  2. 1. Soft tissue integration to dental implants

    Author : Maria Welander; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; connective tissue; dental implants; epithelium; gold alloy; histology; peri-implant mucosa; subcrestal placement; titanium; zirconia;

    Abstract : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. READ MORE

  4. 2. On guided bone reformation in the maxillary sinus to enable placement and integration of endosseous implants. Clinical and experimental studies

    Author : Giovanni Cricchio; Stefan Lundgren; Lars Sennerby; Gerry Raghoebar; Umeå universitet; []
    Keywords : bone grafting; donor morbidity; iliac crest; dental implants; membrane elevation; maxillary sinus floor elevation;

    Abstract : Dental caries and periodontal disease are the major causes for tooth loss. While dental caries commonly involve the posterior teeth in both jaws, the teeth most commonly lost due to periodontal problems are the first and second molars in the maxilla. As a consequence, the upper posterior jaw is frequently edentulous. READ MORE

  6. 4. Analysis of Sub-Synchronous Oscillations in Wind Power Plants

    Author : Muhammad Taha Ali; Mehrdad Ghandari; Massimo Bongiorno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Doubly fed Induction generator; eigenvalue analysis; sub-synchronous control interaction; voltage source converter; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The modern power system is moving towards the high integration of renewable energy sources at a fast pace. The integration of wind power in the power system raises many challenges along with the benefits. One of the recent challenges is the sub-synchronous oscillation (SSO) that occurs in doubly-fed induction generator (DFIG) based wind farms. READ MORE

  7. 5. Peak and Power Reduction in Multicarrier Communication Systems

    Author : Niklas Andgart; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

    Abstract : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. READ MORE
