1. 16. Computational Design in the AEC industry : Applications and Limitations

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Rasmus Mikaelsson; [2022]
   Keywords : Parametric design; generative design; design automation; design exploration; architectural engineering construction;

   Abstract : The AEC-industry need to respond to multiple requirements from regulations and clients, leading to that building projects are becoming increasingly complex to handle for designers. CAD or computer aided design is a way to handle these challenges, and within CAD a new method is emerging: Computational design enables users to generate and explore design solutions automatically.

3. 17. 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

4. 18. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

   University essay from KTH/Teknisk mekanik

   Author : Martin Persson; [2022]
   Keywords : Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

   Abstract : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. READ MORE

5. 19. 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.

6. 20. Designing a better soundscape for the home office : Devlopment of acoustic furniture

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Hanna Mattsson; Theodor Mihel; [2021]
   Keywords : Industrial design engineering; Human centered design; Acoustic design; Furniture design; Product development; Home office; Sound environment; Teknisk design; människocentrerad design; Akustisk design; Möbeldesign; Produktutveckling; Hemmakontor; Ljudmiljö;

   Abstract : As Covid-19 spread throughout the world in the early months of 2020 many people’s lives changed drastically. The situation forced millions of workers and students to start performing their work remotely from home. Currently in Sweden statistics shows that every third person working does it from home at least once a week. READ MORE
