  1. 1. Industrial Scenario using LTE Cellular Network

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Anthony Owondo; Javad Blouchi; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. LÄS MER

  2. 2. Quality Assessment of Thin Polymer Components using NonDestructive Testing : Degree Project for Master of Science in Mechanical Engineering with emphasis on Applied Mechanics

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Markus Nilsson; Tom Carlén; [2019]
    Nyckelord :nondestructive testing; polymer; nonlinear acoustics; instant dynamics amplitude recovery.; oförstörande provning; polymer; olinjär akustik; instant dynamics amplitude recovery;

    Sammanfattning : Polymer components are used in many different applications, including in industries where critical applications put high requirements regarding quality assessment. Such applications might include medical or food where the presence of discontinuities might induce bacterial growth or other unpleasantries, thus certain manufacturers must be able to maintain a zero-tolerance towards damaged components.

  3. 3. Re-synthesis of instrumental sounds with Machine Learning and a Frequency Modulation synthesizer

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

    Författare :Philip Claesson; [2019]
    Nyckelord :machine learning; regression; classification; frequency modulation synthesis; re-synthesis; ;

    Sammanfattning : Frequency Modulation (FM) based re-synthesis to find the parameter values which best make a FM-synthesizer produce an output sound as similar as possible to a given target sound is a challenging problem. The search space of a commercial synthesizer is often non-linear and high dimensional. LÄS MER

  4. 4. Development of new criteria for train detection and evaluation in critical conditions

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

    Författare :Sofiane Kerbal; [2019]
    Nyckelord :railway signaling; train detection; track circuit; shunt; frequency modulation; frequency-shift keying modulation; third-order harmonic; short-time Fourier transform; power spectral density estimation; cross-correlation;

    Sammanfattning : Railway signaling is of paramount importance to ensure traffic management andsafety on the rail network. The main lines are divided into sections called ‘blocks’,which are governed by a fixed signal installation. To prevent trains from colliding,each block allows one train at once. LÄS MER

  5. 5. Sensorless algorithm for synchronous machines using current oversampling and PWM harmonics

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

    Författare :Giorgio Gullone; [2018]
    Nyckelord :;

    Sammanfattning : Sensorless-controlled drives represent a solution drawing an increasinglyimportant attention for the benefits they entail. At the cost ofa slightly lower dynamics compared with the traditional drives, theyinvolve a reduction of the system costs and complexity and improvednoise immunity and reliability. LÄS MER
