  1. 1. Automatic retrieval of data for industrial machines with handheld devices : Positioning in indoor environments using iBeacons

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Linus Sjöbro; [2021]
    Keywords : RSSI; KNN; fingerprints; indoor positioning; Apple; iOS; application; iBeacon; Beacon;

    Abstract : Positioning of mobile phones or other handheld devices in indoor environments is hard because it’s often not possible to retrieve a GPS-signal. Therefore, other techniques need to be used for this. Despite the difficulties with indoor positioning, the Swedish mining company LKAB want to do exactly this in their processing plants. READ MORE

  2. 2. Measuring Respiratory Frequency Using Optronics and Computer Vision

    University essay from Linköpings universitet/Datorseende; Linköpings universitet/Datorseende

    Author : Per Antonsson; Jesper Johansson; [2021]
    Keywords : Computer Vision; Optical Flow; Motion Vectors; Respiratory Frequency; Signal Processing;

    Abstract : This thesis investigates the development and use of software to measure respiratory frequency on cows using optronics and computer vision. It examines mainly two different strategies of image and signal processing and their performances for different input qualities. READ MORE

  3. 3. Exploring Change Point Detection in Network Equipment Logs

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Tim Björk; [2021]
    Keywords : Change point detection; log change detection; time series data; signal processing;

    Abstract : Change point detection (CPD) is the method of detecting sudden changes in timeseries, and its importance is great concerning network traffic. With increased knowledge of occurring changes in data logs due to updates in networking equipment,a deeper understanding is allowed for interactions between the updates and theoperational resource usage.

  4. 4. Experimental acceleration Measurements and Finite Elements Modeling

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Ibrahim Alnimairi; Salim Arrabi; [2021]
    Keywords : signal processing. PSD; mode shapes; Mdof; Sdof; PSDT-SVD; finite element modelling;

    Abstract : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. READ MORE

  5. 5. Speaker Recognition using Biology-Inspired Feature Extraction

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Edvin Andersson; [2021]
    Keywords : Artificial Intelligence; AI; Machine Learning; Speaker Recognition; Technology and Engineering;

    Abstract : Distinguishing between people's voices is something the human brain does naturally, using only frequencies picked up by the inner ear. The field of speaker recognition is concerned with making machines do the same thing using digitally sampled speech and data processing. READ MORE
