Title: Time-dependent conformal mappings with applications to nonlinear sloshing

Speaker: Dr Matt Turner, University of Surrey

Organiser: Department of Engineering

Time and date: 2-3pm, Wednesday 29th of November 2017

Venue: McLellan Room, Engineering Building

Abstract:

In this talk we examine two key features of time-dependent conformal mappings in doubly-connected regions, the evolution of the conformal modulus, Q(t), and the boundary transformation generalizing the Hilbert transform. Results of this theory are applied to inviscid, incompressible, irrotational fluid sloshing in a rectangular vessel. It is shown that the explicit calculation of the conformal modulus is essential to correctly predict features of the flow, such as the free surface evolution.

We also present results for fully dynamic simulations which use a time-dependent conformal mapping and the Garrick generalization of the Hilbert transform to map the physical domain to a time-dependent rectangle in the computational domain. The results of this new approach are compared to the complementary numerical scheme of Frandsen (2004) and it is shown that correct calculation of the conformal modulus is essential in order to obtain agreement between the two methods.

 


 

Title: Challenges of seamless communication

Speaker: Dr Glenfor Mapp, Midlesex University

Organiser: Department of Engineering

Time and date: 2-3 pm, Wednesday 22nd of November 2017

Venue: Bennett Building, Lower Ground Floor Lecture Theatre 5

Abstract:

Due to the development of several wireless technologies, seamless communication, in which users are always connected to the networking infrastructure, is now possible. However, there are still significant hurdles to be overcome to produce techniques and mechanisms that can be actually deployed in the real world.  In that regard, highly mobile environments, such as vehicular networks, present very serious challenges to achieving this goal.

The talk first looks at the issues of providing ubiquitous seamless communication. It initially does so in the context of the Y-Comm Framework and then looks at how the results from this framework can be used to analyse seamless communication in Vehicular Ad-Hoc Networks (VANETs). In order to explore this further, two VANET testbeds have been built.  This talk will detail their development and deployment as well as the results obtained from these experimental systems. The talk concludes by looking at how new types of networks, such as VANETs, will affect the evolution of the Future Internet.



 

Title: Space & Space Park at the University of Leicester

Speaker: Professor Mark Sims, University of Leicester

Organiser: Department of Engineering

Time and date: 12:00-1:00 pm, Wednesday 15th of November 2017

Venue: Belvoir Park Lounge, Charles Wilson, 2nd floor

Abstract:

Prof. Mark Sims obtained his PhD from the University of Leicester, working on x-ray astronomy shadow cameras. He was a European Space Agency Research Fellow based at ESTEC, Noordwijk, the Netherlands working on high energy x-ray astronomy detectors from May 1981 to January 1984. He returned to Leicester in February 1984 and since then he has been involved in about 9 space missions with roles from data analysis, through launch site operations to flight operations, and acting as Principal Investigator on the Life Marker Chip (LMC) life detection instrument based upon immuno-assay techniques on ExoMars. He chaired the STFC Aurora (Space Exploration) Advisory Committee from 2005 to 2009 and is currently a member of the National Space Technology Steering Group (NSTSG)  and a member of the UK Space Agency’s Space Technology Advisory Committee (STAC).

During this seminar, Prof. Sims will talk about his current interests on Space research, and the Space Park at the University of Leicester. The Space Park Leicester is an ambitious initiative to develop a global hub and collaborative community based on space and space-enabled technologies . Based in Leicester, adjacent to the National Space Centre, the Park's first building are expected to be ready in 2019. It is part of the Leicestershire Enterprise Zone and was formally launched in March 2017 as part of the Government's Midlands Engine strategy with an allocation of £12.87 million. The Space Park is a collaboration between the University of Leicester, the City of Leicester and the Leicester and Leicestershire Economic Partnership (LLEP). When fully open, the Park will combine University research and teaching facilities with a range of research institutions and international commercial partners. Alongside the development of a new generation of cutting-edge satellite technology, the site will be home to detailed analysis of space-enabled data that can transform sectors such as international communications, resource management, environmental monitoring and disaster relief.

 


 

Title: Rolls-Royce 1st generation powder nickel disc alloy RR1000

Speaker: Dr Wei Li, Rolls-Royce

Organiser: Department of Engineering

Time and date: 10:00-11:00 am, Wednesday 8th of November 2017

Venue: Belvoir Park Annexe, Charles Wilson

AbstractRR1000 is a powder disc alloy developed by Rolls-Royce. The journey of R&D was long and arduous but also rewarding. There have been many interesting findings with the technology being steadily scaled up from laboratory specimen towards engine component.  There is still room for further research into the material behaviour, which means opportunities for the industrial and academic partners.

 


 

Title: Stability of oscillatory rotating disk boundary layers

Speaker: Scott  Morgan, Cardiff University

Organiser: Department of Engineering

Time and date: 2:00-4:00 pm, Wednesday 1st of November 2017

Venue: McLellan Room, Engineering Building

AbstractThe rotating disk boundary layer has long been considered as providing an archetypal model for studying the stability of three-dimensional boundary-layer flows, and the crossflow inflexion point instability mechanism is common to both the rotating disk boundary layer and the flow over a swept wing. Thus the investigation of strategies for controlling the behaviour of disturbances that develop in the rotating disk flow may prove to be helpful for the identification and assessment of aerodynamical technologies that have the potential to maintain laminar flow over swept wings. We will consider the changes in the stability behaviour that arise when the rotating disk base-flow configuration is altered by imposing a periodic modulation in the rotation rate of the disk surface. Thomas et. al. [Proc. R. Soc. A (2011) 467:2643-2662] have previously demonstrated that Tollmien-Schlichting waves can be stabilised when a similarly induced Stokes layer is conjoined to a plane channel flow. Current work encompasses three distinct investigatory approaches. Linearised direct numerical simulations have been conducted, using the vorticity-based methods that were first adopted by Davies & Carpenter [J. Comput. Phys (2001) 172:119-165]. These simulations are complemented by a local in time linear stability analysis, that is made possible by imposing an artificial frozen base-flow approximation. This localised analysis is deployed together with a more exact global treatment based upon Floquet theory, which avoids the need for any simplification of the temporal dependency of the base-flow.

 


 

Title: Photo-induced force microscopy: a technique for hyperspectral nanochemical mapping

Speaker: Dr Sung Park, Molecular Vista

Organiser: Department of Engineering

Time and date: 3:00-4:00 pm, Wednesday 25th of October 2017

Venue: Room 119, Michael Atiyah Building

Abstract: Infrared Photo-induced Force Microscopy (IR PiFM) is based on an atomic force microscopy (AFM) platform that is coupled to a widely tunable mid-IR laser. PiFM measures the dipole induced at or near the surface of a sample by an excitation light source by detecting the dipole-dipole force that exists between the induced dipole in the sample and the mirror image dipole in the metallic AFM tip. This interaction is strongly affected by the optical absorption spectrum of the sample, thereby providing a significant spectral contrast mechanism which can be used to differentiate between chemical species. Due to its AFM heritage, PiFM acquires both the topography and spectral images concurrently and naturally provides information on the relationship between local chemistry and topology with sub 10 nm spatial resolution on a variety of samples. PiFM spectral images surpass spectral images that are generated via other techniques such as scanning transmission X-ray microscopy (based on synchrotron source), micro confocal Raman microscopy, and electron microscopes, both in spatial resolution and chemical specificity. The breadth of the capabilities of PiFM will be highlighted by presenting data on various material systems (organics, inorganics, 1D/2D, bio-molecules, and nano-photonic materials). By enabling imaging at the nm-scale with chemical specificity, PiFM provides a powerful new analytical method for deepening our understanding of nanomaterials and facilitating technological applications of such materials.

 


 

Title: Control of multivariable systems using classical control techniques

Speaker: Dr Carlos Ugalde-Loo, Cardiff University

Organiser: Department of Engineering

Time and date: 2:00-3:00 pm, Wednesday 25th of October 2017

Venue: Room 119, Michael Atiyah Building

Abstract: Typically, the performance of a control design task is specified in pairs: in terms of an output response to a given input. This is clear for single-input single-output (SISO) problems, but is also convenient for multiple-input multiple-output (MIMO, multivariable) systems. The control system analysis and design for SISO plants may be relatively simple and classical tools (such as Bode/ Nyquist/ Nichols plots, root locus) can be applied following plant linearization. In this context, stability margins are well accepted measures to assess the performance and robustness of the control system. The problem becomes challenging whenever the plant is MIMO - particularly if cross-coupling is strong. Individual channel analysis and design (ICAD) is a frequency domain based analysis and control design framework that can be used to investigate the potential and limitations for the feedback design of any MIMO linear time-invariant system. It is an interactive process involving the required specifications, plant characteristics and the multivariable feedback design process. A key feature of ICAD is that classical control techniques can be employed irrespective of coupling circumstances. To achieve this, the multivariable plant is represented by an equivalent set of SISO systems, where the MIMO nature of the plant is encapsulated in multivariable structure functions with no loss of information. In this presentation, some insight into the use of ICAD will be provided through representative examples. As it will be observed, ICAD can be employed to design high-performance and highly robust control systems.

 


 

Title: An integrated meta analysis of the breast cancer transcriptome for the identification of markers associated with proliferation

Speaker: Professor Graham Ball, Nottingham Trent University

Organiser: Department of Engineering

Time and date: 2:00-3:00 pm, Wednesday 18th of October 2017

Venue: Room 119, Michael Atiyah Building

Abstract: Cancer is a complex disease with a myriad of forms and prognoses occurring within each type.  For example in breast cancer using genomic profiling in excess of 80 sub types have been identified.   The ability to characterise the disease for each patient may offer the potential to assess the molecular sub-type of the disease and thus accurately determine the patients’ prognostic outcome.  Methodologies such as mass spectrometry based proteomics and gene expression arrays offer the potential for characterisation of disease derived samples using a huge number of proteins or genes.  This depth of information while providing a comprehensive overview of a disease state also proves problematic in its complexity.  One has to search through potentially hundreds of thousands of pieces of information for consistent features that address a clinical question in the population. The human mind is very good at finding patterns in a system but is not able to conduct the task repetitively for large numbers of parameters.  Conversely computers are very good at searching for features in such a data space but previously defined statistical methods are not able to cope with the high complexity.  Here we present the application of Artificial Neural Networks (ANNs, a form of artificial intelligence having the characteristics of both human pattern recognition and computer automated searching) to finding genomic solutions to questions in cancer.  Here we present the use of a range of statistical and artificial intelligence based machine learning techniques to develop prognostic models for breast cancer.

 


 

Title: The use of CFD in the design of a 1000mph car - BLOODHOUND SSC, an engineering adventure

Speaker: Dr Ben Evans, Swansea University

Organiser: Department of Engineering

Time and date: 2:00-3:00 pm, Wednesday 11th of October 2017

Venue: Room 119, Michael Atiyah Building

AbstractThe BLOODHOUND Supersonic Car, launched by Richard Noble and Andy Green in October 2008 is set to take the Land Speed Record into a whole new speed regime.  The team, including researchers from Swansea University at its heart, plans to take a manned vehicle to 1000mph by 2018, increasing the current Land Speed Record (763mph) by over 30%.  This target presents the team with massive scientific and engineering challenges, not least of which being how the car will stay attached to the ground at these speeds.  The Computational Fluid Dynamics research team at The College of Engineering at Swansea University has been working on answering these questions, and predicting the overall aerodynamic behaviour of such a vehicle. High Performance Computing was used as an integral component of the design and optimization cycles for the vehicle.  In order to achieve the final design predicted lift and drag responses over 14 full vehicle design iterations were carried out and numerous sub-assembly optimization studies. The design work on this vehicle has inspired the development of novel methods for simulating high speed particle entrainment, mesh-based optimization and CFD data visualization.  The BLOODHOUND SSC vehicle has now been built with testing set to commence in October 2017.

Speaker: Professor Baicheng Lu, Chinese Academy of Engineering and Tsinghua University

Organiser: Department of Engineering

Time and date: 2:00-3:00 pm, Monday 31st of July 2017

Venue: Lecture Theatre 1, Engineering Building

Abstract: China manufacturing industry is big with tremendous achievements in recent 30 more years. Nevertheless, China manufacturing industry is not strong, and also faces a number of new challenges. Since 2013, “Strategy Study for a Strong manufacturing Country” is underway by the Chinese Academy of Engineering. As a result, an action program titled “China Manufacturing 2025” was proposed by CAE and approved by the State Council in early 2014. Then, the official document “China Manufacturing 2025”, drafted by the Ministry of Industry and Information Technology, was announced by State Council in May 19 of 2015. A three-step strategic target for strong manufacturing industry is put forward, and the first strategic step is to make China manufacturing industry entering into the strong manufacturing community of the world in 2025. Hence, five guiding principles, nine strategic missions and five important projects, such as improving manufacturing innovation system, intelligent manufacturing, strengthening manufacturing fundamentals, green manufacturing and developing high end equipment are put forward in the action program.

Title: Fluid mechanics: complexity at all scales

Speaker: Professor Stephen Garrett

Organiser: Professor Mark Peel, Provost

Time and date: 5:30 pm, Tuesday 20th of June 2017

Venue: LT1 Charles Wilson Building

RSVP: inaugural@le.ac.uk

Abstract: Classical fluid mechanics might be dismissed as a simple application of Newton’s laws. The equations that govern the air flow over an A380’s wings can be written down easily, so isn’t fluids done and dusted as a research topic? What more can we possibly hope it will give us? Why does it continue to attract and entertain some of the brightest minds? Why is it still funded? Fluids is taught in all engineering, physics and mathematics programmes around the world. But where should it really sit within the often fiercely protected bounds between the traditional disciplines? Does it really matter anyway? In this lecture, Professor Garrett uses his own research path as a way of exploring the vastness of the subject and perhaps hint at some answers to these questions.



 

Title: Integrated computational materials engineering

Speaker: Dr Shuanglin Chen, Deputy Director of CompuTherm

Organiser: IMPaCT EPSRC Centre for Doctoral Training

Time and date: 3:00-4:00 pm, Monday 19th of June 2017

Venue: LT2 Engineering Building

Abstract: Integrated Computational Materials Engineering (ICME) has recently been highlighted as a methodology that can unlock great potential and benefits in cost-effective materials and process design. The CALPHAD method, which was first developed for the calculation of multi-component phase diagrams, has now been applied to a variety fields in materials science and engineering. The capabilities of CALPHAD-based modeling tools have been extended from calculating phase stability and thermodynamics of a materials system to simulating precipitation and diffusion kinetics. These modeling tools are regularly used by ICME practitioners to accelerate alloy design and development. This presentation will give a brief introduction to the modeling tools developed by CompuTherm based on the CALPHAD method. Unique features of our modeling tools, such as contour diagrams and high-throughput calculations, will be highlighted. Examples will be presented to demonstrate the successful applications of these modeling tools in ICME.
