"קפיצה, תעופה, שחיה וריחרוח"- מחקר ביומימטי באוניברסיטת מנצ'סטר

Biography

Ben Parslew’s academic background is in aerospace engineering, fluid dynamics and biomechanics. His research lies at the interface of engineering and biology, with particular interests in animal locomotion, unmanned aerial vehicles, aerodynamics, robotics and computer animation. Ben is a senior lecturer in Aerospace Engineering at University of Manchester in UK, and also a visiting lecturer at Chulalongkorn University in Thailand.


 

Abstract

This presentation will discuss the links between animals and robotics that are being explored by the University Manchester. We follow two complementary approaches: the first is biomimetics – where nature inspires design; the second is to use engineered systems to gain insights into the natural world. An example of this second approach would be to engineer a legged walking robot – not because legs are necessarily better than wheels – but just as a means of gaining a deeper insight into the biomechanics of how animals walk.

In this presentation a summary will be given of the biological systems on which we have focussed. Many of these are connected to flight, especially birds – whether it be perching pigeons or swimming penguins. We have also worked on flying insects, both from a theoretical perspective and in micro-UAV development. And we have worked on non-flying animals: some examples of physical hopping robots will be shown, including our current work on designing a hopping robot for lunar exploration. Aside from mobile robots, the presentation will overview our other biologically  relevant engineering projects on odour plume tracking, and our goal to develop mobile sniffer robots that can help to manage urban air pollution in future cities.

The role of bioengineering in protecting patients from medical device-related pressure ulcers

Professor Amit Gefen

COVID-19 has brought the effects of pressure ulcers (PUs, also known as pressure injuries) and device-related pressure ulcers (DRPUs) in particular, into sharp focus. With the unprecedentedly high usage of critical care medical devices for the diagnosis and treatment of patients who have COVID-19 with breathing problems, such as noninvasive ventilation by means of continuous positive airway pressure masks or invasive ventilation and feeding tubing in the more severe cases, the incidence of DRPUs has risen starkly. In my departmental seminar, I will explore the currently known aetiology of PUs from a biomechanical and mechanobiological perspective, with focus on the potential PU risks associated with use of medical devices during the current COVID-19 pandemic. I will also describe the worrying mechanobiological links between the known aetiology of PUs and COVID-19. Lastly, I will discuss relevant bioengineering research that is underway and the long-term research & development work needed for minimizing the risk of DRPUs.

Direct Solution of Scattering Problems Using  Generalized Source Integral Equations

 

 

אבסטרקט

 

 

Recent years have seen an increasing interest in the development of fast direct integral equation solvers. These do not rely on the convergence of iterative procedures for obtaining the solution. Instead, they compute a compressed factorized form of the impedance matrix resulting from the discretization of an underlying integral equation. The compressed form can then be applied to multiple right-hand sides, at a relatively low additional cost. The most common class of direct integral equation solvers exploits the rank-deficiency of off-diagonal blocks of the impedance matrix, in order to express them in a compressed manner. However, such rank deficiency is inherent to problems of small size compared to the wavelength as well as to problems of reduced dimensionality, e.g., elongated and quasi-planar problems.

The presented work proposes a class of Generalized Source Integral Equation (GSIE) formulations, which aim to extend the range of problems exhibiting inherent rank-deficiency. The new formulation effectively reduces the problem’s dimensionality and, thus, allows for efficient low-rank matrix compression. When the formulation is used with a hierarchical matrix compression and factorization algorithm, a fast direct solver is obtained. The computational bottlenecks introduced by the proposed generalized formulation are reduced by using non-uniform sampling-based techniques. These techniques are described in detail for one choice of generalized sources. The formulation’s properties and limitations are studied and its use for the development of a fast direct solver is showcased.
