Reliability Prediction and Sensitivity Analysis of Web Services Composition InTech
Duhang Zhong; Zhichang Qi; Xishan Xu.
In this paper, we introduce an approach to predict the reliability of Web services composition. We present the transformation algorithms from BPEL, which is the de facto industry standard of Web services composition specification, to CSPN models. Using the model, we can compute the reliability prediction of the web service composition. The major contribution of this paper is a reliability prediction technique that takes into account the structure of BPEL specification and the concurrent nature of service composition. For future work, we will transform all control-flow constructs of BPEL (including link, scope, faultHandler etc) into Petri nets. And we will use our CSPN model to give a more precise estimation of the reliability and performance of web...

Risk Evaluation of Human-Care Robots InTech
Makoto Nokata; Koji Ikuta.
This chapter presented the study of a safety strategy for human-care robots. Case study of assessing several human-care robots was carried out according to ISO/TR 12100-1:1992 and ISO 14121:1999. The problems of assessing these robots were discussed, a safety strategy for human-care robots has been proposed. Determine limits of special factors, judgments by certification system, benefit of robots for user have been added to the strategy. I undertook a new study of safety in the coexistent space of human and machine in order to realize a human-care robot for the nursing of the aged or disabled. First, the human injury from robot and machine was investigated thoroughly, and I found that it was important to treat safety strategies in the light of mechanical...

Robust and Accurate Detection of Object Orientation and ID without Color Segmentation InTech
Hironobu Fujiyoshi; Tomoyuki Nagahashi; Shoichi Shimizu.
This section describes some of the benefits of the proposed method. - Easy set up To register reference patterns for each robot's ID, orientation is obtained by clicking on the fronts of the robots to assign an ID to each one. There is no need to make a rule-based reference table to identify objects. - Easy patch modification Since the white bar is used to estimate the robot's orientation in the general method, there is less space in which to paste sub-marker patches. This means that our method allows for more space on the top of the robot and that is very easy to modify the patch pattern because of its easy set up. - Robustness with respect to varying light conditions There is no perfect color segmentation. Even if the lighting conditions change, because...

Robust Feature Detection Using 2D Wavelet Transform under Low Light Environment InTech
Youngouk Kim; Jihoon Lee; Woon Cho; Changwoo Park; Changhan Park; Joonki Paik.
The paper presents a local feature detection method for vSLAM-based self-localization of mobile robots. Extraction of strong feature points enables accurate self-localization under various conditions. We first proposed NAST pre-processing filter to enhance low light-level input images. The SIFT algorithm was modified by adopting wavelet transform instead of Gaussian pyramid construction. The wavelet-based pyramid outperformed the original SIFT in the sense of processing time and quality of extracted keypoints. A more efficient local feature detector and a compensation scheme of noise due to the low contrast images are also proposed. The proposed scene recognition method is robust against scale, rotation, and noise in the local feature space.

Stabilization of Fuzzy Takagi - Sugeno Descriptor Models; Application to a Double Inverted Pendulum InTech
Thierry Marie Guerra; Sebastien Delprat; Salim Labiod.
The chapter focused on TS fuzzy models in descriptor form stabilization. As for classical TS models, they can be obtained in a systematic way using the sector nonlinearity approach. Their main interest is to remain close to the nonlinear model. Thus, in some cases the number of models involved can be highly reduced in comparison to a classical TS model representing the same nonlinear model. Hence, the results obtained with the conditions of stabilization can allow reducing in a large way the conservatism of preceding classical results. Nevertheless, if we want to outperform basic conditions of stabilization for TS models in the descriptor form, a way is to use specific matrix transformation. The application of matrix transformation allowed outperforming...

The Surgeon's Third Hand an Interactive Robotic C-Arm Fluoroscope InTech
Norbert Binder; Christoph Bodensteiner; Lars Matthaeus; Rainer Burgkart; Achim Schweikard.
Experiments with this world's first fully robotized C-arm show very promising results. Movements in the image plane, longbone images, data acquisition for 3D reconstruction, and landmark based positioning were successfully implemented and tested. The next version of our C-arm will overcome mechanical problems such as lacking positioning accuracy and mechanical deformation. The value of an every-day OR-device can be increased by simple means. The workflow can be optimized and mistakes can be prevented. Operation time is saved and radiation dose for patient and staff is minimized. The experiences of this study have already been transferred to other systems such as OR microscope (Knopp et al. 2004) and showed similar promising results. Chances are that the...
