  1. 6. Den intelligenta pumpstationen -Optimering av energiförbrukningoch utveckling avautomatiseringsfunktion förfelhantering

    M1-uppsats, KTH/Data- och elektroteknik

    Författare :Kristoffer Karlsson; [2017]
    Nyckelord :Wastewater pumping stations; energy optimization; Fuzzy controller; P controller; on off control; PLC; detection function; cleaning function; Avloppspumpstation; energioptimering; Fuzzy-regulator P-regulator; Start stopp-styrning; PLC; detekteringsfunktion; rengöringsfunktion;

    Sammanfattning : Detta arbete har undersökt möjligheten att via styrsystemet för en avloppspump-station optimera energiförbrukningen av pumpar och med styrfunktioner förenkla driftunderhållet av stationen.För att undersöka energiförbrukningen har en teoretisk modell av en pumpstation gjorts där energitester för tre olika reglermetoder simulerats.

  3. 7. Workload prediction for resource management in data centers

    Magister-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Tuan Anh Le; [2016]
    Nyckelord :;

    Sammanfattning : Resource management is to arrange and allocate resources for computing operations and applications. In large scale data centers that contain thousands of servers, resource management is critical for efficient operation. LÄS MER

  4. 8. Takagi-Sugeno and Mamdani Fuzzy Control of a Resort Management System

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Lujiao Tan; [2012]
    Nyckelord :Fuzzy set theory; Takagi-Sugeno Controller; Mamdani Controller; Resort Management System; T-norms; OWA;

    Sammanfattning : By means of fuzzy set theory as well as Takagi-Sugeno and Mamdani fuzzy controller, this paper presents the investigation of a Resort Management System implemented by a combination of a T-S model and a Mamdani model. It demonstrates the procedure of the specific premise parameters identification and consequence parameters identification performed by regression knowledge in the T-S model, and the process of the fuzzification, the rule base creation and the defuzzification with COG technique in the Mamdani model.

  5. 9. Fuzzy Logic and Approximate Reasoning

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Abdul Khaliq; Amais Ahmad; [2010]
    Nyckelord :Fuzzy; Logic; approximate; reasoning;

    Sammanfattning : Two of the most exemplary capabilities of the human mind are the capability of using perceptions (human knowledge) in purposeful ways and the capability of approximating perceptions by statements in natural language. Understanding these capabilities and emulating them by linguistic approximation is the crux of our thesis. LÄS MER

  7. 10. Fuzzy Modeling of Uplink Transmit Power Control in a CDMA Network

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Victor Uzoechi; Kenneth Osigwe; [2008]
    Nyckelord :cellular; channel; co-channel interference; code division multiple access; distributed power control; fast fading; fixed step power control; fuzzy aggregation; fuzzy connectives; fuzzy control; fuzzy operation; fuzzy set; linguistic variable; mobile; multipath; pathloss; power control; proportional-plus-integral control; radio resource management; reuse distance; reverse link; signal-to-interference ratio; slow fading; spread spectrum; target SIR; transmit power control;

    Sammanfattning : From its beginning, transmit power has always placed a significant constraint on the performance of wireless radio systems. The transmit power control problem can be characterized as that of maintaining adequate power in each transmitted waveform so as to increase the expectation that the minimum required SIR at the receiver will at least be reached.
