  1. 1. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Huong Nguyen; [2023]
    Keywords : Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Abstract : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

  3. 2. Simulation of Mechanical Shock with Finite Element Analysis and Estimation of Shock Attenuation

    University essay from KTH/Hållfasthetslära

    Author : Cheng Qian; [2021]
    Keywords : shock; SRS; FEA; attenuation; chock; SRS; FEA; chockdämpning;

    Abstract : Space equipment is often subjected to mechanical shocks. Some devices like electronics are sensitive to shocks, and they can easily be damaged. To protect these devices, it is important to study shock penetrations in space structures. The Finite Element Method is an effective tool to simulate response to transient excitations. READ MORE

  4. 3. Tank-to-Wheel Energy Breakdown Analysis

    University essay from KTH/Fordonsdynamik

    Author : Xu Yu; [2020]
    Keywords : Hybrid electric vehicle; Energy analysis; Sankey diagram; Vehicle simulation; Energy management system; Driving pattern recognition; Plug-in hybrid; energianalys; Sankey diagram; fordonssimulering; energihanteringssystem; detektering av körbeteende;

    Abstract : In early design phase for new hybrid electric vehicle (HEV) powertrains, simulation isused for the estimation of vehicle fuel consumption. For hybrid electric powertrains,fuel consumption is highly related to powertrain efficiency. READ MORE

  5. 4. Energy analysis of a hybrid forwarder

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

    Author : Wenqi Wu; [2017]
    Keywords : active suspension; pendulum arm; Adams co-simulation; hydraulic simulation; energy consumption; Aktiv dämpning; pendelarm; Adams; samsimulering; hydraulisk simulering; energiförbrukning;

    Abstract : This report is the result of Master of Science thesis project developed for KTH Royal Institute of Technology in collaboration with the Forestry Research Institute of Sweden (Skogforsk) for the Forestry Master Thesis School 2016. In the past few years, Adams MBD models have been created to verify the better comfortability of six-wheeled pendulum-arm-suspension compared to bogie-suspended forwarder. READ MORE

  6. 5. Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

    University essay from SLU/Dept. of Energy and Technology

    Author : Johanna Grim; [2014]
    Keywords : biogas; hygienisering; pastörisering; energibehov; biogasproduktion;

    Abstract : The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. READ MORE
