Fiber Bragg Gratings (FBGs) as integrated spectral fiber reflection filters have found many applications in the fields of communication and sensing. Different techniques such as the phase mask method or the interferometric method are used for recording of such FBGs with UV-light. Interferometric recording during the fiber drawing process allows the realization of complex FBG-arrays in a simple way. Such FBG-arrays are especially interesting for (quasi-) distributed fiber optical sensing systems allowing measurement in parallel at different locations. We will report about improvements in dynamic recording (single pulse recording) of such FBG-arrays achieving high reflection intensities in the range of 10%. this has been achieved by optimised doping and processing of the fiber. Applications of such FBGs for measuring parameters like temperature and strain will be discussed including a specific spectral measuring system based on a grating polychromator for multiplexed measurements.
Most HPC systems are clusters of shared memory nodes. parallel programming must combine the distributed memory paralleliza-tion on the node inter-connect withthe shared memory parallelization inside of each node. thi...

the BMI Eigenvalue Problem is one of optimization problems and is to minimize the greatest eigenvalue or a bilinear matrix function. this paper proposes a parallel algorithm to compute the ϵ-optimal solution of the BMI Eigenvalue Problem on parallel and distributedcomputing systems. the proposed algorithm performs a parallel branch and bound method to compute the e-optimal solution using the Master-Worker paradigm. the performance evaluation results on PC clusters and a Grid computing system showed that the proposed algorithm reduced computation time of the BMI Eigenvalue problem to 1/91 of the sequential computation time on. a PC cluster with 128CPUs and reduced that to 1/7 on a Grid computing system. the results also showed that tuning of the computational granularity on a worker was required to achieve the best performance on a Grid computing system.

It seems reasonable to expect that the general public will demand in not too distant future to institute more stringent certification procedures for computing parts of traditional and new-generation safety-critical application systems. Such quality-of-service (QoS) certification processes will not and can not rely solely on the testing approach. Design-time guaranteeing of timely service capabilities of various subsystems is an inevitable part of such processes. Although some promising developments in this area have been occurring in recent years, the technological challenges yet to be overcome are enormous. this paper is a summary of the author's perspective on the remaining challenges and promising directions for tackling them.

Asynchronous real-time distributed systems raise fundamental issues of how to build timely systems that operate in the presence of uncertain timeliness, and furthermore, how to certify that such systems will deliver properties including timeliness and safety. In this paper, we discuss an approach for constructing certifiable asynchronous real-time distributed systems.
