Façade refurbishment of existing office buildings: Do conventional energy-saving interventions always work? (2015)
Journal Article
Pomponi, F., Farr, E. R., Piroozfar, P., & Gates, J. R. (2015). Façade refurbishment of existing office buildings: Do conventional energy-saving interventions always work?. Journal of Building Engineering, 3, 135-143. https://doi.org/10.1016/j.jobe.2015.07.003

Offices account for 40% of energy use in construction sector. Office building stock is already under-performing and dilapidating at a fast pace. With the current rate of replacing old building stock in the UK, it is expected that at least 60% of what...

Influence of gravel density in the behaviour of soft soils improved with stone columns (2015)
Journal Article
Miranda, M., Da Costa, A., Castro, J., & Sagaseta, C. (2015). Influence of gravel density in the behaviour of soft soils improved with stone columns. Canadian geotechnical journal. Revue canadienne de géotechnique, 52(12), 1968-1980. https://doi.org/10.1139/cgj-2014-0487

Stone columns are frequently employed to improve the bearing capacity of soft soils, to reduce settlements, and to increase the speed of consolidation. Their behaviour depends on several factors, such as the density of the aggregate that forms the co...

The complex integral method for solving ordinary differential equations in series [3, 7, 8] is extended to cover the series solution of partial differential equations also. The means of this extension is straightforward, with both ‘ordinary’ and ‘Fro... Read More about Series solutions of partial differential equations using the complex integral method.

Similarity solutions to unsteady pseudoplastic flow near a moving wall (2014)

It is shown that similarity solutions to a partial differential boundary value
problem for power law fluids may be generated by the application of a multi-parameter
stretching group. Furthermore, the resulting ordinary differential
boundary value... Read More about Similarity solutions to unsteady pseudoplastic flow near a moving wall.
