A constraint-net approach to the resolution of conflicts in a product with multi-technology requirements (2009)
Journal Article
Medland, A. J., Matthews, J., & Mullineux, G. (2009). A constraint-net approach to the resolution of conflicts in a product with multi-technology requirements. International Journal of Computer Integrated Manufacturing, 22(3), 199-209. https://doi.org/10.1080/09511920802372286

While many procedures exist to support the systematic development of a product, it is often difficult to create an environment in which the early stages of the design are resolved. This can particularly happen when the product design is based upon a... Read More about A constraint-net approach to the resolution of conflicts in a product with multi-technology requirements.

An algebraic multigrid method for high order time-discretizations of the div-grad and the curl-curl equations (2009)
Journal Article
Boonen, T., Van lent, J., & Vandewalle, S. (2009). An algebraic multigrid method for high order time-discretizations of the div-grad and the curl-curl equations. Applied Numerical Mathematics, 59(3-4), 507-521. https://doi.org/10.1016/j.apnum.2008.03.004

We present an algebraic multigrid algorithm for fully coupled implicit Runge-Kutta and Boundary Value Method time-discretizations of the div-grad and curl-curl equations. The algorithm uses a blocksmoother and a multigrid hierarchy derived from the h...

Effects of spark-assistance on controlled auto-ignition combustion at different injection timings in a multicylinder direct-injection gasoline engine (2009)
Journal Article
Yang, C., Kalian, N., & Zhao, H. (2009). Effects of spark-assistance on controlled auto-ignition combustion at different injection timings in a multicylinder direct-injection gasoline engine. International Journal of Engine Research, 10(3), 133-148. https://doi.org/10.1243/14680874JER03209

Controlled auto-ignition (CAI) combustion, also known as homogeneous charge compression ignition (HCCI) can be achieved by trapping residuals with early exhaust valve closure in a direct fuel injection in-cylinder four-stroke gasoline engines. CAI co... Read More about Effects of spark-assistance on controlled auto-ignition combustion at different injection timings in a multicylinder direct-injection gasoline engine.

Optimal bed allocation in hospitals (2009)
Journal Article
Li, X., Beullens, P., Jones, D., & Tamiz, M. (2009). Optimal bed allocation in hospitals. Lecture Notes in Economics and Mathematical Systems, 618, 253-265. https://doi.org/10.1007/978-3-540-85646-7_24

In this paper a decision aiding model is introduced for optimizing the allocation of beds in a hospital. The model is based on queueing theory and goal programming (GP). Queueing theory is used to obtain some essential characteristics of access to va... Read More about Optimal bed allocation in hospitals.

Effect of vapour force at the blow-open process in double-break contacts (2009)
Journal Article
Bizjak, M., Kharin, S., & Nouri, H. (2009). Effect of vapour force at the blow-open process in double-break contacts. IEEE Transactions on Components and Packaging Technologies, 32(1), 180-190. https://doi.org/10.1109/TCAPT.2009.2013986

This paper presents results of a theoretical and experimental investigation of the phenomena of electrical contact repulsion and its associated blow-off characteristics at high current. The voltage and current waveforms as well as contact's displacem... Read More about Effect of vapour force at the blow-open process in double-break contacts.

A macroscopic probabilistic model of adaptive foraging in swarm robotics systems (2009)
Presentation / Conference
Liu, W., & Winfield, A. F. (2009, February). A macroscopic probabilistic model of adaptive foraging in swarm robotics systems. Paper presented at 6th Vienna International Conference on Mathematical Modelling, Vienna

In this paper, we extend a macroscopic probabilistic model of a swarm of foraging robots from the homogeneous to the heterogeneous case. In the swarm, each robot is capable of adjusting its searching time and resting time thresholds following the rul...

Case study: Constraint-based improvement of an overwrapping machine (2009)
Journal Article
Neale, G., Mullineux, G., Matthews, J., & Medland, T. (2009). Case study: Constraint-based improvement of an overwrapping machine. Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 223(2), 207-216. https://doi.org/10.1243/09544054JEM1189

The paper presents the successful application of a constraint-based modelling to improve the performance of an overwrapping packaging machine. The constraint-based modelling was employed to manipulate the geometry of the individual components and the... Read More about Case study: Constraint-based improvement of an overwrapping machine.
