This paper describes a stereo-imaging system for variable distances. The setup includes a mechanical mount system-holder, a control unit for the correct positioning of the cameras, the cameras itself and the object to capture. The goal of this setup was to achieve a true sense of scale and depth of the filmed material on dynamically variable distances to the object. This demands certain requirements which are usually not necessary for many applications of stereoscopic filming. In the last step, the resulting material is prepared for viewing.
The efficient use of future MPSoCs with f 000 or more processor cores requires new means of resource-aware programming to deal with increasing imperfections such as process variation, fault rates, aging effects, and p...

In order to measure the effectiveness of safety protection systems there are several design parameters. Diagnostic coverage factor is one of the most important parameter which influences all architectures. In this short paper the relationship between PFD avg , DC and T I are presented. 1oo2 and 1oo2D architectures are considered as examples.

In some fields such as Mathematics Mechanization, automated reasoning and Trustworthy Computing, etc., exact results are needed. Symbolic computations are used to obtain the exact results. Symbolic computations are of high complexity. In order to improve the situation, exact interpolating methods are often proposed for the exact results and approximate interpolating methods for the ap- proximate ones. In this paper, the authors study how to obtain exact interpolation polynomial with rational coefficients by approximate interpolating methods.
While using a single GPU is fairly easy, using multiple CPUs and GPUs potentially distributed over multiple machines is hard because data needs to be kept consistent using message exchange and the load needs to be bal...

Simultaneous Localization and Mapping (SLAM) algorithms with multiple autonomous robots have received considerable attention in recent years. In general, SLAM algorithms use odometry information and measurements from exteroceptive sensors of robots. The accuracy of these measurements and the performance of the corresponding SLAM algorithm directly affect the overall success of the system. This paper presents comparative performance evaluations of three Simultaneous Localization and Mapping (SLAM) algorithms using Extended Kalman Filter (EKF), Compressed Extended Kalman Filter (CEKF) and Unscented Kalman Filter (UKF). Specifically, it focuses on their SLAM performances and processing time requirements. To show the effect of CPU power on the processing time of SLAM algorithms, two notebooks and a netbook with different specifications have been used. Comparative simulation results show that processing time requirements are consistent with the computational complexities of SLAM algorithms. The results we obtained are consistent with the CPU power tests of independent organizations and show that higher processing power decreases processing time accordingly. The results also show that CEKF is more suitable for outdoor SLAM applications where there are a lot of natural and artificial features.
In the standard IEC 61508 miscellaneous architectures for safety related systems are introduced. Depending on the required safety, reliability and availability levels several architectures such as 1002-, 2002-, 1003-,...
