  1. 1. ESTIMATION OF RADIATION EXPOSURE FROM NATURALLY OCCURRING RADIONUCLIDES IN FOOD AND FOODSTUFF

    University essay from

    Author : Ida Bengtsson; [2022-01-13]
    Keywords : Medical physics; Naturally occurring radionuclides; committed effective dose from ingested radionuclides; Biokinetic models;

    Abstract : Purpose: The main purpose of this study was to provide an estimation of the committed effective dose received by the Swedish population from naturally occurring radionuclides (NORM) in the diet. This study was also aiming to investigate the impact on the committed effective dose due to the new developments in the biokinetic model for Po 210 . READ MORE

  3. 2. Deep Learning Approach for Extracting Heart Rate Variability from a Photoplethysmographic Signal

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Gudny Björk Odinsdottir; Jesper Larsson; [2020]
    Keywords : Heart rate variability; photoplethysmograpic signal; human activity recognition; deep learning approach; recurrent neural network; long short-term memory network;

    Abstract : Photoplethysmography (PPG) is a method to detect blood volume changes in every heartbeat. The peaks in the PPG signal corresponds to the electrical impulses sent by the heart. The duration between each heartbeat varies, and these variances are better known as heart rate variability (HRV). READ MORE

  4. 3. Dopamine replacement therapy reduces beta band burst duration in Parkinson’s disease

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Alessandro Mecconi; [2017]
    Keywords : Parkinson s disease; computational neuroscience; DBS;

    Abstract : One of the main characteristics of Parkinson's disease (PD) is an exaggerated oscillatory activity in the beta band (12-30 Hz). This activity has been linked to the rise of symptoms such as bradykinesia and akinesia. READ MORE

  5. 4. Prediction Models of Shrinkage and Creep in Industrial Floors and Overlays

    University essay from KTH/Byggvetenskap

    Author : Aida Freidriks; [2015]
    Keywords : Computations; concrete; creep; industrial floors; overlays; prediction models; shrinkage;

    Abstract : All form of activity in a building is in need for a sound platform to be able to operate. The performance of concrete floor in industrial spaces is of importance because there are greater demands on industrial concrete floor. READ MORE

  6. 5. System Surveillance

    University essay from Statistik; Tekniska högskolan

    Author : Shaheer Mansoor; [2013]
    Keywords : State Space Models; Forecasting; Wavelets; LOESS; Change Point Detection; Financial Systems; Trading; Transactions per second; Kalman Filtering;

    Abstract : In recent years, trade activity in stock markets has increased substantially. This is mainly attributed to the development of powerful computers and intranets connecting traders to markets across the globe. READ MORE
