  1. 1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Simone Guietti; [2024]
    Keywords : Pintle injector; space propulsion; space engineering;

    Abstract : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. READ MORE

  3. 2. Structural Analysis and Redesign of a L90 Front Axle Casing

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Erik Berra Widén; [2023]
    Keywords : FEM; Ansys Mechanical; Axle Casing; Volvo CE; Wheel Loader; Redesign;

    Abstract : This thesis was commissioned by Volvo Construction Equipment (Volvo CE) to redesign the front axle casing of their L90 wheel loader to be more in line with their larger wheel loaders. The current L90 front axle casing consists of two parts bolted together in the middle. READ MORE

  4. 3. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Filip Ekblom; [2023]
    Keywords : Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Abstract : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. READ MORE

  5. 4. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

    University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Erik Lindén; [2023]
    Keywords : PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

    Abstract : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. READ MORE

  6. 5. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Ellen Lundin; Lovisa Liljenberg; [2023]
    Keywords : LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE
