Director of Advanced VR Research Centre - The Centre for Virtual Engineering

Roy Kalawsky is Professor of Systems Engineering and Human Computer Integration. He is the Director of the Advanced VR Research Centre (established 1995 - opened by HRH Duke of Edinburgh) which is a state of the art centre for Virtual Engineering research.

He was the Director of the Research School of Systems Engineering and Technical Head of the Systems Engineering Innovation Centre (between 2006 and 2013). He previously headed up the Systems Division within the Department of Electronic and Electrical Engineering, before becoming Associate Dean (Enterprise). He was previously Head of Dept Computer Science at Loughborough University (between 2000-2004).

Prior to his appointment at Loughborough University he was with BAE Systems (nearly 18 years) starting as a Systems Engineer in 1978, and eventually became responsible for Cockpit Research and Development across the whole of the Military Aircraft Division.

Research within the AVRRC focusses on developing next generation advanced modelling, simulation and visualization techniques to support a wide range of application areas. In this respect modelling, simulation and visualization (M,S,V) are regarded as a continuous continuum involving abstract or mathematical representations of system behaviour or function through to complex coupled models and simulations that represent significantly complex systems where the human is an integral part of the simulation. Visualization is an integral part of the continuum because it provides the means to interact, probe and investigate the system being modelled. Visualization research spans the field of visual analytics to high fidelity representations of the real world.

This approach is based on a systems engineering methodology where the wider context is considered in defining the relationship of the system with its environment and other components of the system as a whole. The systems engineering discipline ensures we consider the way the resulting models are used as part of a well defined and rigourous work flow. Roy has been applying these model based systems engineering methods to a wide range of sectors including: aerospace, construction, defence, energy, healthcare and transport. This approach has helped examine and refine system architectures to optimise overall system performance against defined requirements and goals. A key thrust of his work from the early 1990s has been model based systems engineering.

No model or simulation can be reliably used without it being validated and verified so an important aspect of Roy's research is involved in developing methods to provide validated system models.

The human dimension of modelling, simulation and visualization underpins all of his research. The human in this context is an integral pt of the system. Consequently, research is being undertaken to improve user's interaction with their data (to gain new insight or greater understanding) by increasing human cognitive and perceptual capability.

He leads the Advanced Systems, Modelling and Simulation Research Group whose research advances modelling and simulation methods to provide greater insight and understanding of extremely complex systems. This research encompasses a wide range of methods from abstract mathematical representations, model driven engineering, sophisticated computer simulations through to hardware in the loop simulation. The focus of this research is not only on development of better modelling and simulation methodologies, but also on the application of state of the art techniques to help understand and predict the behaviour of complex systems. Applications for our research span many industry sectors including aerospace, automotive, construction, counter-terrorism, defence, energy, healthcare and transport.

Professor Kalawsky established the Advanced VR Research Centre (AVRRC) at Loughborough University (in 1995) which hosts a comprehensive state of the art virtual engineering laboratory. At the heart of this laboratory is a suite of advanced interactive visualisation and collaborative environment systems. The AVRRC was identified as one of the e-Science Centres of Excellence and has been extremely successful in securing research funding (several £m) and delivering high quality research for over 15 years.

At the heart of his approach is the strong desire to balance stakeholder perspectives with input from engineering, non-engineering and human factors disciplines. This application of a multi-disciplinary systems engineering methodology is key to performing the cross-domain trade-offs required to deliver future optimal solutions. Verification and validation are foremost in his approach in order to develop appropriate model based systems engineering solutions.

Selected Publications

Kalawsky, R.S., O’Brien, J., Chong, S., Wong, C., Jia, H., Pan, H., and Moore, P., Bridging the Gaps in a Model Based System Engineering Workflow through to Hardware-in-the-Loop Simulation. IEEE Systems Journal, 2013. 0(99): p. 13, DOI: 10.1109/JSYST.2012.2230995

Breakthrough research described in this paper overcame significant challenges in current model based systems engineering by developing one of the first seamless workflows for a model based architecture through to a fully executable model that can be hosted on a range of target platforms, demonstrating real capability for coupled simulations. The research solved previously intractable problems through development of special model transformation tools and bidirectional transformations between platform independent and platform specific solutions. This research led being invited to lead the systems architecture research of the EU Commission’s largest FP7 project (€12m) on Systems of Systems (DANSE - Designing for Adaptability and evolutioN in System of systems Engineering), and more recently a key role in the recently announced InnovateUK/Airbus research project on Agile Integrated Wing (£16m).

The significant research described in this paper describes our successful approach to develop the world’s first relational model transformation engine (implemented as a series of Mixed Integer Linear Programs). This prioritises target model compliance with its meta-model by considering multiple interpretations of applying the transformation specification in order to ensure a correct target model is generated. Two significant contributions include 1) a set-based formal representation of meta-models, models and transformations, that can be manipulated by MILP-like solvers and 2) an original bi-directional transformation semantics that prioritises target model compliance and handles ambiguous or underspecified transformations.

This paper describes our research that led to unique algorithmic solutions to assess quality of image sequences based on human visual perception. Our multi-disciplinary approach overcome current unreliable subjective image quality assessment techniques by dispensing the need for a reference image by precisely correlating with human judgment on quality. Algorithm performance has been validated against a dataset involving 700 image sequences of 5 different categories demonstrating high correlation to desired quality assessment. This unique solution can optimise the quality of compressed images/videos transmitted over low-bandwidth channels meaning that compression algorithms can be specifically optimized for specific applications (eg military).
