  1. 1. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE

  3. 2. Application of Lamb waves using piezoelectric technique for structure health monitoring

    University essay from KTH/Hälsoinformatik och logistik

    Author : Simon Mauritz; [2023]
    Keywords : Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Abstract : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. READ MORE

  4. 3. Mechanical and thermal buckling analysis of laminated composite plates

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Keywords : composite material; Mechanical Buckling; Buckling analysis;

    Abstract : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. READ MORE

  5. 4. Mechanical restraint in psychiatric healthcare facilities : A helpful tool, or torture or other cruel, inhuman or degrading treatment or punishment in disguise?

    University essay from Stockholms universitet/Juridiska institutionen

    Author : Julia Rudhe; [2021]
    Keywords : Mechanical restraint; torture; international human rights; UNCAT; CRPD; survivor-controlled research; bältesläggning;

    Abstract : The use of mechanical restraint is a common practice in psychiatric care, often defended by medical necessity but seldom questioned from a human rights perspective. The purpose of this thesis has been to investigate under which circumstances mechanical restraint by bed through belt fixation could amount to torture and other cruel, inhuman or degrading treatment or punishment.

  6. 5. Quantification of tribological effects in expansion fasteners

    University essay from KTH/Materialvetenskap

    Author : Nicolò Drahorad; [2019]
    Keywords : post-installed anchors; civil construction; tribology; antifriction coatings;

    Abstract : Post-installed anchors for civil construction are elements that ensure the integrity of building structures even under the most severe static, seismic and shock loadings. Despite the high popularity of this technology in construction sites all over the world, the current state of knowledge is limited and there is still a great potential for significant improvements.
