The randomness plays an important role in influencing behaviors of engineering systems, particularly for dynamical systems. In this lecture, taking earthquake engineering as a background, the speaker tries to explain that:
1. By introducing physical laws into a stochastic system, the source of randomness may be revealed, and the essential relationship between the deterministic system and the stochastic system may be revealed as well.
2. For revealing the objective reality, not only the relationship among the physical phenomenon need to be investigated, also the propagation process of randomness in the system needs to be analyzed. The probability density evolution theory offers an elegant means to reveal the propagation mechanism of randomness in a stochastic system.
3. The new viewpoint supplies a novel and feasible way to address a series of problems that remain to be resolved, such as the modelling of stochastic systems, the analysis of nonlinear stochastic systems, the reliability assessment of dynamical systems and the control of nonlinear stochastic systems.
Some illustrative examples are presented in the lecture, including the modeling of earthquake ground motions, the stochastic damage analysis of structures, the dynamic stability and the collapse analysis of complex structures, etc.

In the digital age, the integration of sensing, processing, and sound emission into IoT devices has made their economical deployment in urban environment possible. These intelligent sound sensors, like the Audio Intelligence Monitoring at the Edge (AIME) devices deployed in Singapore, operate 24/7 and adapt to varying environmental conditions. As digital ears complementing the digital eyes of CCTV cameras, these devices provide public agencies with a wealth of aural data, enabling the development of comprehensive and effective sound mitigation policies. In this presentation, we will examine the critical requirements for intelligent sound sensing and explore how deep learning techniques can be utilized to extract meaningful information, such as noise type, dominant noise source direction, sound pressure and frequency of occurrence of the environmental noise. Additionally, we will introduce new deep-learning-based active noise control and mitigation approaches, including reducing noise from entering residential buildings and generating acoustic perfumes to mask annoyance in urban environments; and how these deep learning models can be deployed in an edge-cloud architecture. Our aim is to demonstrate how deep learning models can advance the field of acoustic sensing and noise mitigation and highlight current challenges and trends for future progress.

The protection of large-scale systems against the harmful effects of vibration has become a major field of research in recent years. In the literature of vibration control of mechanical, electrical or hydraulic systems, different damping systems, mainly passive, active and semi-active damping systems or, recently, inerter devices, have been proposed and successfully applied to tackle the vibration problem. One critical characteristic common to most of these actuators is that they, in general, exhibit nonlinear dynamics and thus complex control techniques must be employed for an appropriate performance. The main objective of this talk is to present some challenges and recent results on distributed or decentralized passive and active vibrational control schemes with a focus on simplicity, reliability, applicability and robustness of controller developments under information constraints and multiactuation schemes. In particular, to enhance the system protection, some innovative devices for the purpose of vibration mitigation in buildings through efficient control techniques will be analyzed and an integration of actuator devices with different concepts of large structural systems will be analyzed separately. The talk will be concluded with some advices on both technical and practical aspects of vibration control systems using innovative actuation devices.

Flow induced vibrations and noise are usually associated with various technical applications, however fluid-structure interaction (FSI) and later fluid-structure-acoustic interaction (FSAI) problems have become important also in biomechanics of human voice.
Human voice is produced through self-oscillations of the vocal folds (VFs) excited by air flow. The VFs vibration modulates the airstream producing the primary sound in glottis. This signal propagates through the vocal tract (VT) cavities, which modify the primary sound by the acoustic resonances of the VT, forming the acoustic output so-called formants that define vowels. Understanding the principles of voicing is important for treatment of voice disorders. However, the voice production mechanisms are not yet fully understood.
First computational low-order phonation models were based on the VFs self-oscillations modelled by simple mass-spring models coupled to 1D airflow modelling by potential flow and Bernoulli equations. Such models proved very useful and their variants are still widely used. Later, these simple or elastic 2D VF models were excited by 2D airflow modelled by FEM using incompressible Navier-Stokes equations coupled with flow on the vibrating surface.
Recently published studies deal with computer 2D FE modelling, where the vocal folds formed by several materials are considered as nonlinear elastic structure excited by compressible flow coming from the trachea to the simplified model of the VT. This problem requires the solution of flow in time-domain together with VFs deformation with complicated geometry depending on time. The FSAI problem is solved numerically by the space-time discontinuous Galerkin method. The computations show that the nonlinear elasticity is needed for obtaining substantially higher accuracy of the VFs deformation.
Flutter instabilities of structures are mostly unwanted phenomena in technical applications. Another situation is in biomechanics of voice where the flutter instability of VFs creates the voice source. Experimental modelling studies enabled to show how the acoustic resonances can support self-sustained VFs oscillation, i.e. how the VFs oscillation can be strongly influenced by the interaction with acoustic resonances of the VT when the VT is prolonged by so-called resonance tube used in voice therapy methods. This FSAI effect was demonstrated by the relationships of subglottal pressure variation in time versus glottal area variation. It was shown that a part of the airflow energy required for phonation is substituted by acoustic energy, utilizing the first acoustic resonance.

Imagine you are standing on a street corner in a city. Close your eyes: what do you hear? Perhaps some cars and busses driving on the road, footsteps of people on the sidewalk, beeps from a pedestrian crossing, and the hubbub of talking shoppers. You can do the same in a kitchen as someone is making breakfast, or as you are travelling in a vehicle. Now, following the success of AI and machine learning technologies for speech and image recognition, we are beginning to build computer systems to automatically recognize real-world sound scenes and events. In this talk, we will explore some of the work going on in this rapidly expanding research area, and discuss some of the potential applications emerging for sound recognition, from home security and assisted living to environmental noise and sound archives. We will also outline how we are adopting participatory methods to help us realise the potential benefit of sound sensing to society and the economy.
