  1. 1. Fall detection bracelet with an accelerometer and cellular connectivity

    University essay from Uppsala universitet/Signaler och System

    Author : Ola Hammarstedt; [2019]
    Keywords : Fall detection; Accelerometer; ADXL345;

    Abstract : This thesis aims at developing a prototype for a fall detection bracelet that can connect to the cellular network. The bracelet consists of a processing unit, three sensors, a LTE USB modem and a powerbank. The prototype is aimed at elderly people since up to one out of three over the age of 65-years-old fall each year. READ MORE

  2. 2. Throughflow Study on Bleeding for Part Load Compressor Operation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Hedkvist; [2019]
    Keywords : Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

    Abstract : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. READ MORE

  3. 3. Plant phenology and climate change : possible effect on the onset of various wild plant species first flowering day in the UK

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nigel Fox; [2019]
    Keywords : geography; GIS; plants; phenology; climate change; global warming; FFD; IPCC; Bluebell; Garlic mustard; Coltsfoot; Cuckooflower; United Kingdom; Woodland Trust; UK; Earth and Environmental Sciences;

    Abstract : The IPCC states that the planet is significantly warming due to effects of climate change. This warming effect has consequences for phenological events. Many species cannot track rapid climate change, resulting in phenological mismatches. This study looks at an extreme weather event and the longer-term effects of climate change. READ MORE

  4. 4. Propane Heat Pump Modelling and Monitoring for System Control Analysis

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Fernando Mengod Bautista; [2019]
    Keywords : ;

    Abstract : The objective of this master thesis was the performance analysis of a non-conventional heating system layout based on a propane heat pump unit. The objective had been pursued by monitoring and modelling the system. First, the project focused on monitoring the system, since for a correct modelling it was necessary to have all the data of the system. READ MORE

  5. 5. Temporal and Spatial Models for Temperature Estimation Using Vehicle Data

    University essay from Linköpings universitet/Reglerteknik

    Author : Lisa Eriksson; [2019]
    Keywords : Temperature Estimation; Temporal Dependency; Spatial Dependency; Kalman Filter; EKF; Data Fusion; CP; CV; Singer Model;

    Abstract : Safe driving is a topic of multiple factors where the road surface condition is one. Knowledge about the road status can for instance indicate whether it is risk for low friction and thereby help increase the safety in traffic. The ambient temperature is an important factor when determining the road surface condition and is therefore in focus. READ MORE
