Visit to Japan

November 2008

Renata Jarzebinska and Steve James visited Kitakyushu University to attend the 2nd International Optical Sensors Symposium for optical sensor development and applications, organised by Professor Bill Batty of Cranfield University at Kitakyushu. Steve presented two papers describing the group's activities in gas sensing and in fibre optic sensing, while the collaborative work of the EPG and Prof. S W Lee's group from the University of Kitakyushu on fibre optic chemical sensing was presented by Dr. Sergiy Korposh of KKU.

The highly successful symposium was followed by a two-day workshop of optical fibre sensors, and spent a further, very fruitful two weeks in Prof. Lee's labs.

Summer in Hull

June - September 2008

Members of the EPG team (Edmond Chehura, Ricardo Correia, Jin Li, Steve James, and Steve Staines) spent much of the summer installing fibre Bragg grating sensors on foundation piles at sites in Hull and in North London. The work, funded by the EPSRC Challenging Engineering Award, was aimed at investigating the use of static, statnamic, and dynamic testing to assess the health of foundation piles, and to investigate the load bearing capacity of a new design for foundation piles. Details of the test will be posted soon.

The Japanese connection

February 2008

Steve James visited Kitakyushu University in Japan to make a presentation at a symposium on the EPG's work on fibre optic sensors based on LPGs coated with nano-structured coatings, and to spend some time working in the laboratories of Professor S-W Lee, a chemistry professor, running a research group with interests in the use of nanomaterials for chemical sensing.

Prof. Lee then visited Cranfield with members of his team to continue the work. The results of which will be published shortly.

Prof. Lee's visit was closely followed by a visit from Dr. Suzuki, also of Kitakyushu University, who came to undertake collaborative work in the field of speckle interferometry.
