  1. 11. Evaluation of SCPT-surveys as method for accessing dynamic modulus

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Joakim Granskär; [2018]
    Keywords : SCPT; Dynamic modulus; Seismic surveys;

    Abstract : The purpose of this master thesis is to evaluate the results from the completed SCPT (Seismic Cone Penetration Test) surveys with respect to the methods ability to estimate dynamic young´s modulus. This has been done by comparing the result from SCPT to other seismic methods and dynamic parameters converted from “static” geotechnical surveys. READ MORE

  3. 12. Binder Migration in Double Pressed Drill Bit Inserts

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Axel Bjerke; [2018]
    Keywords : Physics and Astronomy;

    Abstract : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. READ MORE

  4. 13. Ram pump hydraulic air test. Pressure conditions and flow measurements: Experimental research and case study

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Paula María Arizcun Zúñiga; [2018]
    Keywords : Ram pump; water hammer; pressure; efficiency; installation; drive pipe; delivery pipe; impulse valve;

    Abstract : This study consists of the development of a ram pump, which will allow the pumping of water without the need of external energy sources. It is considered an analysis of interest since, once it is finished; it can be applied in reality improving and facilitating different activities related to agriculture and health. READ MORE

  5. 14. Methodology and vibrational analysis for measurements on a VTOL RAPS

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dino Krantz; [2017]
    Keywords : Experimental modal analysis; impact hammer test; methodology; structural vibration; RPAS; VTOL; Certification;

    Abstract : In this thesis a methodology for measuring vibrations has been produced andinvestigated for APID 60, a rotorcraft in a Vertical Take-off and landing remotelypiloted aircraft system (VTOL RPAS). A comparative study was carried out forthe purpose of identifying the methodology with respect to design modificationscommon to the APID 60. READ MORE

  6. 15. Experimental verification of an instrument to test flooring materials.

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Rony Philip; [2017]
    Keywords : Fluid model; coefficients of the floor; linear dynamics; Matlab; least square method.;

    Abstract : The focus of the project is to validate the fluid model with different flooring materials and the measurements of an instrument to test flooring materials and its force attenuating capabilities using mathematical models to describe the signature and coefficients of the floor.As a part of improving the knowledge about the linear dynamics of vibrations involved during the sudden impact caused on hip bones of elderly people during fall.
