Embark on a pioneering PhD journey in aircraft noise modeling and contribute to the future of silent, eco-friendly flight! OverviewAs urban air mobility (UAM) evolves, introducing air taxis and delivery drones to densely populated cities, understanding the human impact of these new noise sources is essential. The complexity of urban structures and the presence of existing noise sources necessitate scientific inquiry into their effects on residents.Current knowledge gaps stem from the inadequacy of existing models to accurately represent UAM noise in urban settings. Traditional noise studies focus on high-exposure areas, such as near runways or flight paths, and fail to account for urban influences on sound propagation. The intricate nature of urban environments requires advanced modeling techniques to analyze how noise from UAM vehicles affects inhabitants.An improved model will enhance our understanding of urban noise perception and guide strategies for noise reduction, whether by optimizing aircraft design, adjusting operational conditions, or utilizing innovative urban materials and landscaping.Project ScopeThe selected candidate will concentrate on urban environments, crafting a model to predict frequency-dependent noise levels generated by UAM vehicles. This model will analyze sound intensity, frequency spectrum, and phase differences, closely mimicking real-world urban acoustics. The outcome will yield both monaural sound levels for noise impact assessments and binaural time signals for applications in virtual reality, such as NLR's Virtual Community Noise Simulator (VCNS). This model will serve both perception studies and evaluations of how aircraft noise propagates within urban areas.A validation study of this model is crucial, incorporating both objective and subjective assessments to refine its accuracy.

Join the Software Improvement Group (SIG) as a Master's Research Intern and be at the forefront of advancing software quality assessment methodologies. This internship focuses on estimating the risk and value of software qualities, providing a unique opportunity to investigate the critical factors that influence software engineering success.Research Problem:In the realm of software engineering, three main elements govern decision-making: technology, people/process, and economics. As software quality increasingly dictates the success or failure of systems, it is essential for development organizations to grasp the potential risks and benefits, alongside the costs associated with enhancing software quality. Unfortunately, an integrated methodology to address various software qualities is currently lacking.At SIG, we utilize the Cost Estimation Model (Nuhogro 2011) to evaluate the effect of maintainability on development efforts, which serves as a vital tool for reporting and decision-making. However, we are in need of similar assessments for other software quality characteristics.The FAIR methodology (FAIR, Open-FAIR, Freund 2015) offers a structured approach for quantifying risks, particularly in the context of cybersecurity. This methodology combines multiple risk factors to assess overall risk and provides outcome ranges.Research Question:This research aims to explore whether the FAIR approach, or a similar alternative, can be adapted for various quality models (such as maintainability, security, architecture quality, etc.), resulting in a comprehensive cost estimation model for multiple software qualities. Furthermore, the research will investigate if risk models for these qualities can converge into a unified software economics model.If this is not feasible, can the FAIR methodology be applied to software security, leveraging results from SIG’s Sigrid platform?Tentative Approach:The research is expected to unfold in several stages, although not all stages need to be completed within a single thesis project.
