  1. 1. Election Forecasting in a Multiparty System

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Stefan Lindborg; [2019-01-31]
    Nyckelord :Election forecasting; Polling; Multiparty systems; Dynamic Linear Models; DLM; Kalman filtering; Swedish elections;

    Sammanfattning : This bachelor thesis in statistics covers the subject of election forecasting in a multipartysystem, using polling data, that is data collected to measure party support, and dynamiclinear models (DLMs) with Kalman filtering. In terms of decision-making the outcomeof an election can be thought of as an uncertainty. LÄS MER

  2. 2. Region Proposal Based Object Detectors Integrated With an Extended Kalman Filter for a Robust Detect-Tracking Algorithm

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Gabriel Khajo; [2019]
    Nyckelord :Object Detection; Extended Kalman Filter; Tracking;

    Sammanfattning : In this thesis we present a detect-tracking algorithm (see figure 3.1) that combines the detection robustness of static region proposal based object detectors, like the faster region convolutional neural network (R-CNN) and the region-based fully convolutional networks (R-FCN) model, with the tracking prediction strength of extended Kalman filters, by using, what we have called, a translating and non-rigid user input region of interest (RoI-) mapping.

  3. 3. A filter in the chain of command : A quantitative study on the extent to which officials in the Swedish Government Offices perceive that they are governed bythe political elite and ministerial advisers

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Njord Frölander; [2019]
    Nyckelord :Officials; The Swedish Government Offices; Political staff; Public administration; Political elite; Ministerial advisers; Tjänstemän; Regeringskansliet; Den politiska staben; Offentlig förvaltning; Den politiska ledningen; Politiska tjänstemän;

    Sammanfattning : The aim of this thesis is to investigate to what extent the officials within the Swedish Government Offices consider themselves to be governed by the political elite (ministers and state secretaries) and the ministerial advisers (chief of staffs, planning directors, political advisers and press secretaries). In an ideal chain of command, the political elite governs the officials, since the ministers are appointed by the Prime Minister to govern the Government Office’s different policy areas. LÄS MER

  4. 4. Wireless electrocardiogram based on ultra-wideband communications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Maria Toll; [2019]
    Nyckelord :UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Sammanfattning : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

  5. 5. Analog Front End Development for the Large Hadron Collider Interlock Beam Position Monitor Upgrade

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

    Författare :Oskar Björkqvist; [2019]
    Nyckelord :;

    Sammanfattning : The interlock Beam Position Monitor (BPM) system in the Large Hadron Collider(LHC) is responsible for monitoring the particle beam position at the point of thebeam dump kicker magnets and is part of the machine protection system. Thecurrent interlock BPM system has some limitations and because of this, an upgradeproject has been initiated. LÄS MER
