  1. 11. Optimization of Heterogeneous Parallel Computing Systems using Machine Learning

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Devi Abhiseshu Adurti; Mohit Battu; [2021]
    Nyckelord :Application; Heterogeneous systems; Parallel computing; Machine learning; Optimization;

    Sammanfattning : Background: Heterogeneous parallel computing systems utilize the combination of different resources CPUs and GPUs to achieve high performance and, reduced latency and energy consumption. Programming applications that target various processing units requires employing different tools and programming models/languages. LÄS MER

  3. 12. Transformation Techniques to Facilitate Hardware Acceleration of Workloads

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Oscar Manuel Castro Otárola; [2021]
    Nyckelord :;

    Sammanfattning : There are many hardware and software techniques to decrease the execution time in a high workload computation program. The software techniques do not require extra hardware and could be a cheaper and easier solution. LÄS MER

  4. 13. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

    Master-uppsats, KTH/Rymdteknik

    Författare :Hasan Basaran; [2020]
    Nyckelord :Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

    Sammanfattning : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.

  5. 14. Joint Estimation and Calibration for Motion Sensor

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Peng Liu; [2020]
    Nyckelord :State space model; accelerometer array; parameter estimation; Maximum Likelihood; Expectation Maximization; Gradient Descent; ill-conditioned matrix.; tillståndsmodell; accelerometerarray; parameterskattning; maximimetoden; väntevärdesmaximering; gradientsökning; illakonditionerade matriser.;

    Sammanfattning : In the thesis, a calibration method for positions of each accelerometer in an Inertial Sensor Array (IMU) sensor array is designed and implemented. In order to model the motion of the sensor array in the real world, we build up a state space model. Based on the model we use, the problem is to estimate the parameters within the state space model.

  7. 15. A Comparison between Different Recommender System Approaches for a Book and an Author Recommender System

    Master-uppsats, Linköpings universitet/Interaktiva och kognitiva system

    Författare :Jesper Hedlund; Emma Nilsson Tengstrand; [2020]
    Nyckelord :Recommender System; Collaborative Filter; Matrix Factorization; Content-based Filter; Doc2Vec;

    Sammanfattning : A recommender system is a popular tool used by companies to increase customer satisfaction and to increase revenue. Collaborative filtering and content-based filtering are the two most common approaches when implementing a recommender system, where the former provides recommendations based on user behaviour, and the latter uses the characteristics of the items that are recommended.
