  1. 6. Design, manufacturing and qualification of an ejection system for small satellites

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Stefano Bassoli; [2021]
    Keywords : ;

    Abstract : The Bistable Boom Dynamic Deployment (B2D2) experiment aims to demonstrate the deployment of a two-meter self-deployable boom in order to conduct high quality magnetic field measurements. The boom will be placed in a Free Falling Unit, ejected from a sounding rocket launched within the REXUS programme. READ MORE

  3. 7. To be a chick mother : variation in maternal care and its effect on chick behavioural development

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Linnéa Christenson; [2021]
    Keywords : maternal behaviour; natural broodiness; induced broodiness; social ranking; hen chick interaction; chick behavioural development; poultry; layers; feather peck;

    Abstract : In Swedish poultry production today over 7 million chicks are incubated, housed and reared without maternal care. Studies indicate that chicks behavioural development and welfare may benefit from hen maternal care and potentially maternal care could be artificially provided in the commercial situation.

  4. 8. The effect of stripe width, stripe overlap, gas flow, and scan angle on process stability in Laser Powder Bed Fusion (L-PBF)

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Carl Högman; [2021]
    Keywords : Additive Manufacturing; Laser Powder Bed Fusion; Process Stability; Process Parameters;

    Abstract : It is known that altering different processing parameters will yield completely different results in additive manufacturing. Some of the most common ones to alter to increase material quality or to increase productivity are laser power, hatch distance, layer thickness and scan speed. READ MORE

  5. 9. Optimization of laser powder bed fusion process parameters for 316L stainless steel

    University essay from Uppsala universitet/Oorganisk kemi

    Author : William Hahne; [2021]
    Keywords : Additive manufacturing; Stainless steel; 316L; Laser powder bed fusion; Powder bed fusion; Build rate; Powder layer thickness;

    Abstract : The interest for additive manufacturing techniques have in recent years increased considerably because of their association to good printing resolution, unique design possibilities and microstructure. In this master project, 316L stainless steel was printed using metal laser powder bed fusion in an attempt to find process parameters which yield good productivity while maintaining as good material properties as possible.
