  1. 11. Multiple Aspects of Dynamic Rating in the Power System

    Författare :Seyede Fatemeh Hajeforosh; Math Bollen; Sarah Rönnberg; Alfredo Vaccaro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic rating; Transmission lines; Overload Protection; Stochastic analysis; Hosting capacity; Transformers; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : Increased consumption and increased use of renewable energy make overhead lines and transformers more often congested. Dynamic rating (DR) uses a time-depending maximum permissible current instead of a long-term-fixed rating; it is an effective solution to upgrade the capacity of existing grid assets to minimize this congestion.

  2. 12. Vibrations in timber floors : Dynamic properties and human perception

    Författare :Kirsi Jarnerö; Anders Professor; Tomi Toratti; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

    Sammanfattning : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. LÄS MER

  3. 13. Programming Language Design - Issues in Web Programming and Security

    Författare :Niklas Broberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Functional programming; web programming; dynamic loading; regular expressions; security; non-interference; calculus; core calculus; bisimulation; calculus;

    Sammanfattning : This thesis consists of two separate parts. Both concern programming language design, the first in the domain of web programming and the other for security. LÄS MER

  4. 14. Operator and Machine Models for Dynamic Simulation of Construction Machinery

    Författare :Reno Filla; Jan-Ove Palmberg; Jonas Larsson; Allan Ericsson; Tobias C. Larsson; Linköpings universitet; []
    Nyckelord :dynamic simulation; construction equipment; discrete simulation; continuous simulation; operator model; driver model; integrated product development; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

  5. 15. Synchronous Belt Mechanics and Durability - An Investigation Towards Life Prediction

    Författare :Tomas Johannesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load distribution model; synchronous; camshaft drives; mathematical modelling; timing; belt; dynamic; wear; simulation; automotive; belt life prediction;

    Sammanfattning : An automotive synchronous belt transmits power and assures accurate timing between the crankshaft and camshafts. The automotive industry is very competitive: there is constant pressure to increase performance and lower costs. LÄS MER
