  1. 1. Human Gait Phase Recognition in Embedded Sensor System

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

    Författare :Zhenbang Liu; [2021]
    Nyckelord :State Inference; Gait Phases; Hidden Markov Model; Long Short Term Memory; Tillståndsinferens; gångfaser; Dold Markov modell; långtidsminne;

    Sammanfattning : Gait analysis can improve our understanding of gait to improve medical diagnosis or treatment in clinical assessment. Studying the gait cycle in an embedded sensor system is essential for the detection of any abnormal walking pattern. LÄS MER

  3. 2. Overcoming Inter-carrier-interference in OFDM System

    Magister-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Fukang Guo; Luoan Lu; [2021]
    Nyckelord :ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

    Sammanfattning : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. LÄS MER

  4. 3. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Md Monowarul Islam; Muftadi Ullah Arpon; [2020]
    Nyckelord :CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

    Sammanfattning : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. LÄS MER

  5. 4. Simulation & Analysis of Peer-to-Peer Network Quality for Measurement Scheduling : Online algorithms, Application for Network QoS Monitoring

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

    Författare :Gustaf Lindstedt; [2019]
    Nyckelord :network; measurement; scheduling; peer; simulation; adwin; adaptive; window; mean; variance; online algorithm;

    Sammanfattning : With the growing dependency on Internet connectivity in our daily lives, monitoring connection quality to ensure a good quality of service has become increasingly important. The CheesePi project aims to build a platform for monitoring connection quality from the home user’s perspective. LÄS MER

  7. 5. Geo-distributed multi-layer stream aggregation

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

    Författare :Pietro Cannalire; [2018]
    Nyckelord :stream processing; geo-distributed; architecture; algorithms; windowing; data synopses; Apache Spark Structured Streaming; Apache Kafka; Misra-Gries algorithm; flödesbehandling; geo-distribuerade; arkitekturen; algoritmerna; windowing; data synopses; Apache Spark Structured Streaming; Apache Kafka; Misra-Gries-algoritmen;

    Sammanfattning : The standard processing architectures are enough to satisfy a lot of applications by employing already existing stream processing frameworks which are able to manage distributed data processing. In some specific cases, having geographically distributed data sources requires to distribute even more the processing over a large area by employing a geographically distributed architecture. LÄS MER
