  1. 21. Natural Refrigerants in Data Center Cooling with Thermosiphon Application

    University essay from KTH/Energiteknik

    Author : VICTOR HEINERUD; ANDRÉ SAHLSTEN; [2016]
    Keywords : ;

    Abstract : Ever since the computer was invented, there has been a need of data storage and the demand has strictly grown since. This has resulted in a huge amount of data centers and the trend has shown no signs of changing. The data centers are powered by electricity and in 2010 the electricity consumption for data centers stood for 1. READ MORE

  3. 22. Multi Data center Transaction Chain : Achieving ACID for cross data center multi-key transactions

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Qinjin Wang; [2016]
    Keywords : ;

    Abstract : Transaction support for Geo-replicated storage system is one of the most popular challenges in the last few years. Some systems gave up for supporting transactions and let upper application layer to handle it. READ MORE

  4. 23. Model checking transaction properties for concurrent real-time transactions in UPPAAL

    University essay from Mälardalens högskola/Inbyggda system

    Author : Jinle Li; [2016]
    Keywords : Real-time transaction management; MVCC; model-checking; timeliness; isolation;

    Abstract : As a technique to ensure absence of undesired interference in transactional computations, Concurrency Control (CC) guarantees logical data consistency via providing transaction isolation, thus contributing to their dependability. However, single-version CC, which requires that a transaction system always works on the current version of a data item, may introduce unpredictable delays for real-time transactions because of unbounded blocking time which may cause deadline misses.

  5. 24. A CFD Method for Simulation of Gas-Liquid Flow in Cooling Systems : An Eulerian-Eulerian Approach

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Malin Lind; Karl Johan Josefsson; [2016]
    Keywords : CFD; Gas-Liquid; Two-phase; Eulerian; Air bubbles; Flow; Eulerian-Eulerian; Cooling system;

    Abstract : When designing modern engines it is important to construct a cooling system that cools the engine structure efficiently. Within the cooling system there is always a certain amount of air which can accumulate and form air pockets in critical areas, such as the water jacket, which can lead to wall degradation. READ MORE

  6. 25. CFD analysis of nozzle effect on jet formation

    University essay from KTH/Mekanik

    Author : Mustafa GÜDÜCÜ; [2015]
    Keywords : ;

    Abstract : This project is concerned with CFD simulations of jets issued from elliptical nozzles. The investigated jet flow in this project is turbulent flow emanating from microscopic nozzles into a combustion chamber. READ MORE
