  1. 1. A Multi-Level Perspective: Construction and Demolition Waste Management System : Case Study: Bengaluru

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Prashanth Ramakrishna; [2023]
    Keywords : Bengaluru; C D Waste Management; MLP Theory; Path Dependency;

    Abstract : A significant proportion of construction and demolition (C&D) waste is encompassed within the broader category of global waste. The handling of C&D waste is subject to the influence of a tripartite of environmental, social, and economic factors. READ MORE

  3. 2. "Sound and Vision": Thomas Pynchon, Perception, and Transcendence

    University essay from Lunds universitet/Engelska

    Author : Viktor Ferdinand Kovács; [2023]
    Keywords : Perception; transcendence; auditory self; phenomenology; modalities of experience; perceptual mode; imaginative mode; Thomas Pynchon; Gravity s Rainbow; The Crying of Lot 49; Languages and Literatures;

    Abstract : Previous studies of Thomas Pynchon’s works have made progress in defining numerous aspects of what could be construed as the Pynchonian worldview. However, they have mainly identified them in general, visual terms, separated from the level of the direct experience of his characters. READ MORE

  4. 3. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine

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

    Author : Elina Arvidsson; [2022]
    Keywords : Esrange Space Centre; Flame deflector; Acoustic estimation; Liquid rocket engine; Rocket Factory Augsburg; Jet acoustics; Esrange Space Centre; Flammdeflektor; Akustisk estimering; vätskedriven raketmotor; Rocket Factory Augsburg; strömningsakustik;

    Abstract : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

  5. 4. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

  6. 5. Experimental Study of Installation Effects on Cooling Fan Noise

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Yu-Yu Lu; [2021]
    Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources. READ MORE
