1. All-fibre optical sensor system for chemical sensing based on fibre Bragg grating technology
Abstract : This thesis deals with the realization of an all-fibresensor system for chemical sensing through the evanescentfield, based on fibre Bragg grating technology. The advantagesof all-fibre systems are most apparent for the potential userof the system. These systems are of small size, have highmobility, and require no precision alignment. READ MORE

2. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion
Abstract : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. READ MORE
