  1. 1. A Justified Infringement on Privacy? - A Qualitative Study on the Private Labour Market Actors’ Perceptions of Workplace Drug Testing

    University essay from Göteborgs universitet/Institutionen för socialt arbete

    Author : Anna Asp; [2021-08-25]
    Keywords : Workplace drug test; Privacy; Prevention; Rehabilitation; Stigmatization;

    Abstract : The purpose of this study was to get an understanding of the perceptions and experiencesof drug tests as a measure to prevent substance use at workplaces. The focus was toexplore the perceptions of different actors within the private labour market concerningthe integrity-sensitive aspects that are connected to drug test at work places and tounderstand perceptions on drug prevention, positive test results and drug rehabilitation inrelation to drug tests.

  2. 2. Simulating cable fires in Fire Dynamics Simulator : Based on small scale testing in cone calorimeter

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Hugo Zacharoff; [2021]
    Keywords : Cable fires; FDS; cone calorimeter;

    Abstract : In a society increasingly more influenced by technology and electricity, electrical and computer cables will play a more vital role in humans’ everyday life. With an increasing number of cables being introduced into society, the risk of fires caused by or involving cables will increase and become a more common danger to property and human lives.

  3. 3. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Patrick Johansson; [2021]
    Keywords : CMUT; capacitive; micromachined; ultrasonic; transducer; model;

    Abstract : Capacitive micromachined ultrasonic transducers (CMUT:s) are often used in medical imaging and they show some promise as underwater transducers. This thesis collates the available information about how CMUT:s operate, their strengths and weaknesses and investigates their efficiency as an underwater transducer. READ MORE

  4. 4. Gearbox fault detection, based on Machine Learning of multiple sensors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Armands Krumins; [2021]
    Keywords : condition monitoring; gear; machine learning; surface fatigue;

    Abstract : The increasing demand for higher efficiency and lower environmental impact of transmissions, used in automotive and wind energy industries has created a need for more advanced technical solutions to fulfil those requirements. Condition monitoring plays an important role in the transmission life cycle, saving resources and time. READ MORE

  5. 5. Implementation of thermomechanical laser welding simulation : Predicting displacements of fusing A AISI304 T-JOINT

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Anton Rolseth; Anton Gustafsson; [2021]
    Keywords : Laser welding; Finite element method; ABAQUS; Thermomechanical simulation; Heat source models; DFLUX; Element activation;

    Abstract : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. READ MORE
