A concept study for a bend sensor based on a fibre Bragg grating (FBG) and a compact evaluation unit for the investigated type of sensor is presented. The fibreoptic sensor is capable of resolving the radius and the direction of the bend. The measurement data evaluation unit is capable of resolving multiple distributed FBG sensors, which are present in a single fibre at different positions.

In this paper, we propose an optical burst switching architecture in time division multiplexed wavelength-routing networks, in which an edge OBS node requests time slots necessary to optical bursts to the time division multiplexed wavelength-routing network. Our scheme is attempt to improve the burst contention resolution and optical channel utilization.

Face and facial expressions play essential roles in interpersonal communication. Most of the current works on the facial expression recognition attempt to recognize a small set of the prototypic expressions such as happy, surprise, anger, sad, disgust and fear. However the most of the human emotions are communicated by changes in one or two of discrete features. In this paper, we develop a faci...

We present an automated approach to classify sentences of scholarly work with respect to their rhetorical function. While previous work that achieves this task of argumentative zoning requires richly annotated input, our approach is robust to noise and can process raw text. Even in cases where the input has noise (as is obtained from optical character recognition or text extraction from PDF fil...

Mode group diversity multiplexing (MGDM) has been proposed as a means to create independent, transparent communication channels over a multimode fibre in short reach optical networks. In this paper we provide an experimental investigation of the MGDM technique focusing on the linearity of the fibre’s response and the temporal variations of the transmission matrix coefficients, which describe th...

Over the past few decades, there has been a considerable interest in the use of distributed optical fibre sensors (DOFS) for structural health monitoring of composite structures. In aerospace-related work, health monitoring of the adhesive joints of composites has become more significant, as they can suffer from cracking and delamination, which can have a significant impact on the integrity of ...

Optical pulse compression using similariton propagation in an optical fibre with decreasing dispersion has been demonstrated for the first time. This scheme is a practical application of sech-similariton solution to generalized nonlinear schrodinger equation(NLSE) distributed coefficients recently found self similarity technique. The profile constructed comb-profile approximation technique and ...
