  1. 1. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Venkataramanan Mohandass; [2019]
    Keywords : Alloy 718; additive manufacturing; electron beam-powder bed fusion; surface engineering; shot peening; high temperature corrosion;

    Abstract : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. READ MORE

  2. 2. 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

  3. 3. 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

  4. 4. 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

  5. 5. Cracking in a slender concrete slab due to thermal variation

    University essay from KTH/Betongbyggnad

    Author : Johan Mattsson; Fredrik Åman; [2019]
    Keywords : Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

    Abstract : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. READ MORE
