By the reason of some renewable energy sources not controlled by human begins but natural environment. Especially, wind power and PV generation controlled by the nature, and therefore PV or wind power is difficult to estimate the output. It is useless for engineering system that the system has lower controllability and cannot estimate the operation. The natural energy sources are not control and difficult of estimation. In this paper represents the PV system output model. PV system output models are two types. One is monthly model, and the other is daily model. These model uses sunlight time and angle of the sun and PV cells. To verify these model, apply the 10 kW PV system and compare estimate output with real generation.

In this paper, we describe 3-D display in the aspect of communication technology. 3-D display provides 3-D images to the viewers with more accurate and realistic information than which 2-D display does. This feature is an essential component of communication technology. Generally communication technology pursues for exchanging and sharing of thoughts, feelings and ideas. 3-D displays are effective contact media to achieve these goals. The concept of accessible spatial dimension of a person is used to describe 3-D display in the aspect of communication technology. It is classified into three dimensions and each of dimensions represents the dimension of contact media. Several research results, related with 3-D display and communication technology are introduced based on the concept. Copyright 2009 ACM.

Event log is the important starting point of any process analysis technique. Existent business process analysis techniques are applied mainly to manual or simulated logs, considering mainly information about control perspective. In this paper, we first analyze the feature of data perspective of PLM (Product Lifecycle Management) system in manufacturing area, and extend the MXML format to support the log with data perspective information in PLM domain. Subsequently, we introduce an approach of data cleaning to separate the multi-version process information in real-life data set. In the end, we produce real-life log with information about data perspective in PLM system, then, mine the process model from real-life log and evaluate the proposed approach by fitness measuring. © 2008 IEEE.

Vision-based motion estimation is a key technique in autonomously mobile robot. This paper presents an integrated method for motion estimation of the mobile robot based on floor plane extraction. The whole processes include floor plane extraction, pose estimation of the onboard stereo vision system and motion estimation of the mobile robot. First, based on disparity map obtained from the onboard real-time stereo vision system, a two-stage method is used for fast floor plane extraction. Then all the points belong to the floor plane are transformed from disparity space to Euclidean space, and a simple least squares method is employed to fit the floor plane. The fitting parameters of the floor plane are used for the pose estimation of the onboard stereo vision system. Finally, the motion of the mobile robot is estimated with the tracking results of the points on floor plane. The proposed motion estimation method is intended to be used in the motion control of a wheeled mobile robot. Experimental results in real environments are presented. ©2009 IEEE.

The most important issues of the test framework are its generality, reusability and scalability in a specific area. Mobile application software that constantly updates and improves makes it especially difficult for these points. This paper first proposes the definition of mobile application software, as well as its classification, and summarizes the mobile application software testing technology. Then we introduce the thought of service-oriented architecture into this area, and adopt COM technique, aims at designing a mobile application software test framework. During the design, we focus on the technical implementation and interface definition. Finally a test platform is built based on the framework and used to test a typical software of mobile phone. The test results show that the test framework greatly improved the testing flexibility and provided a good foundation for implementation and expansion of mobile application test.

Effective treatment of chronic radiation proctitis using radiofrequency ablation

Endoscopic argon plasma coagulation and bipolar electrocautery are currently preferred treatments for chronic radiation proctitis, but ulcerations and strictures frequently occur. Radiofrequency ablation (RFA) has been successful for mucosal ablation in the esophagus. Here we report the efficacy of RFA with the BarRx Halo⁹⁰ system in three patients with bleeding from chronic radiation proctitis. In all cases, the procedure was well tolerated and hemostasis was achieved after 1 or 2 RFA sessions. Re-epithelialization of squamous mucosa was observed over areas of prior hemorrhage. No stricturing or ulceration was seen on follow-up up to 19 months after RFA treatment. Real-time endoscopic optical coherence tomography (EOCT) visualized epithelialization and subsurface tissue microvasculature pre- and post-treatment, demonstrating its potential for follow-up assessment of endoscopic therapies. © 2009, SAGE Publications.

Primary Exploration on the Symmetry of Human Walking

Normal walking has often been assumed to be symmetric. A few papers have discussed the kinematic symmetry in healthy adults using statistical and mathematic calculations, but no consensus exists on the methodology. In this paper, we try to define what walking symmetry is and determine mathematical symmetry indices. We have investigated walking symmetry among healthy subjects from 20 to 69 years old by using Fourteen-Linkage (FL) model. In the case of bilateral dynamic gait data, we make use of a dynamic time warping algorithm to calculate the similarity between them. The result shows this method has a good application on describing walking symmetry. The paper analyzes three kinds of symmetry, but here mainly mentions dynamic symmetry.

Feature Selection Methods in Walking Stability Analysis

Walking stability is the main reason for leading to falls for people, especially for elders. But there are much more features related with walking so that we cannot understand which features are more important than others to contribute the walking stability. Almost all of researches focused on some specific features but didn't present any reasons for that. Therefore, the Dynamic Time Warping (DTW) is employed to calculate walking stability, an adaptive Genetic Algorithm (GA) to search the best contributing and representative features, and an improved Support Vector Machine (SVM) to assess the fitness of specific feature combination according to age classification information. After studying walking patterns of 51 healthy male subjects ranging from 21 years old to 66 years old, the 32 most contributing features are acquired. The experiments show that these feature selection methods can improve the discrimination power of walking stability effectively. This research not only supports more convenient data acquisition equipments, but also helps us understand walking stability better.

Continuous functionality of critical infrastructure systems is essential to support the social and economic organization of productive sectors within a country. Electric power, potable water, telecommunications, natural gas, and transportation are examples of these critical systems, whose nature makes them suitable for network analysis. This study presents the topological characterization of the city electric power network. The properties of complex network, including average path length, clustering coefficient and degree distribution, have been studied and the electric power network of a major city in Central China is demonstrated as an example, the result shows that the electric power network exhibits small-world network property with short average path length and high clustering coefficient. Through the analysis about the practical interpretation of those statistical parameters, we propose some possible reasons for these properties. Finally, the vulnerability of electric power network is simulated and analyzed under selective attacks and random failures.
