A Boundary Element Method (BEM) Solver for Low Frequency Room Modes (2022)
Presentation / Conference
Cicero, A., & Hargreaves, J. A. (2022, August). A Boundary Element Method (BEM) Solver for Low Frequency Room Modes. Presented at Internoise 2022, Glasgow, Scotland

Room modes are known to be problematic in small critical listening environments. They degrade the acoustic quality at low frequencies, producing peaks and nulls in the frequency domain and ringing in the time domain. The Finite Element Method (FEM) i...

Analysis and control of acoustic modes in cylindrical cavities with application to Direct Field Acoustic Noise (DFAN) testing (2022)
Presentation / Conference
Hargreaves, J. (2022, August). Analysis and control of acoustic modes in cylindrical cavities with application to Direct Field Acoustic Noise (DFAN) testing. Presented at Internoise 2022, Glasgow, Scotland

It is well known that acoustic cavities have frequencies at which certain free-response ‘modes’ of propagation respond especially strongly. In the absence of significant damping, these cause peaks of high SPL in the frequency response as well as spat...

Raytracing in Galerkin Boundary Integral form (2022)
Presentation / Conference
Emthyas, A., & Hargreaves, J. (2022, August). Raytracing in Galerkin Boundary Integral form. Presented at Internoise 2022, Glasgow, Scotland

Raytracing is an established method for computing the late-time part of room impulse responses. But it has the drawback that only very crude Monte Carlo models of boundary scattering and diffraction are possible to include without losing its attracti...

Generation of noise exposure contours for eVTOL aircraft including transition (2022)
Presentation / Conference
Amargianitakis, D., Self, R., Proenca, A., Torija Martinez, A., & Synodinos, A. (2022, June). Generation of noise exposure contours for eVTOL aircraft including transition. Presented at 28th AIAA/CEAS Aeroacoustics 2022 Conference, Southampton, UK

With the advent of the Urban Air Mobility (UAM) sector, a wide variety of concepts have emerged in academic studies and industry preliminary designs. The majority of these concepts sport Vertical Takeoff and Landing (VTOL) capabilities taking advanta... Read More about Generation of noise exposure contours for eVTOL aircraft including transition.

Development of an evolutionary cost sensitive decision tree induction algorithm (2022)
Presentation / Conference
Kassim, M., & Vadera, S. (2022, May). Development of an evolutionary cost sensitive decision tree induction algorithm. Presented at 2022 IEEE 2nd International Maghreb Meeting of the Conference on Sciences and Techniques of Automatic Control and Computer Engineering (MI-STA), Sabratha, Libya

This paper develops an Evolutionary Elliptical Cost-Sensitive Decision Tree Algorithm (EECSDT) which learns cost-sensitive non-linear decision trees for multiclass problems. EECSDT is developed by formulating the problem as an optimization task in wh... Read More about Development of an evolutionary cost sensitive decision tree induction algorithm.
