A high-frequency BEM for 3D acoustic scattering
Presentation / Conference
Hargreaves, J., Lam, Y., Langdon, S., & Hewitt, D. A high-frequency BEM for 3D acoustic scattering. Presented at 22nd International Congress on Sound and Vibration, Florence. Italy

The Boundary Element Method (BEM) is a powerful method for simulating scattering of acoustic waves which has many advantages, particularly when the problem concerns an object in an unbounded medium. Its applications are however limited in practice be... Read More about A high-frequency BEM for 3D acoustic scattering.

Acoustic cross-energy measures and their applications
Presentation / Conference
Hargreaves, J., & Lam, Y. Acoustic cross-energy measures and their applications. Presented at The 22nd International Congress on Sound and Vibration, Florence. Italy

Acoustic energy density and acoustic intensity are quantities which are well established and widely applied. When these are applied to pressure and particle-velocity fields which are the linear superposition of more than one wave they naturally separ...

Fault tolerant strategy of actuator failure for actively controlled railway wheelsets
Presentation / Conference
Mirzapour, M., Mei, T., & Li, H. Fault tolerant strategy of actuator failure for actively controlled railway wheelsets. Presented at 2014 UKACC International Conference on Control, Loughborough University

This paper presents the development of a fault-tolerant scheme through an analytical redundancy approach for actively controlled railway wheelsets. The main aim of the study is to maintain the basic control of the rail vehicles in the event of actuat...

Towards a full-bandwidth numerical acoustic model
Presentation / Conference
Hargreaves, J., & Lam, Y. Towards a full-bandwidth numerical acoustic model. Presented at Forum Acusticum, Krakow, Poland

Prediction models are at the heart of modern acoustic engineering and are used in a diverse range of applications from refining the acoustic design of classrooms and concert halls to predicting how noise exposure varies through an urban environment....

Perception of noise from large wind turbines (EFP-06 Project)
Report
(EFP-06 Project)

Is noise from large wind turbines more annoying than noise from small wind turbines? This is a question that is discussed widely in the context of a new generation of large wind turbines replacing the traditional smaller ones. To date legislation ta...

Embryonic and fetal development of the white-lipped peccary (Tayassu pecari)
Journal Article
Andrade, R., Monteiro, F., Rocha El Bizri, H., Pantoja, L., Bodmer, R., Valsecchi, J., & Mayor, P. Embryonic and fetal development of the white-lipped peccary (Tayassu pecari). Theriogenology, 119, 163-174. https://doi.org/10.1016/j.theriogenology.2018.07.006

The white-lipped peccary (Tayassu pecari) is an endangered large-sized Neotropical ungulate that is one of the most hunted mammals in the Amazon. Here, we used two embryos and 102 white-lipped peccary fetuses originated from animals hunted for subsis...
