The priori knowledge of PID control can be used to choose the initial weights to make sure that PIDNN control systems are initial stable. Without priori knowledge and using the random initial weights, initial stable of the PIDNN system may be uncertain. The paper proposes an improved algorithm which has momentum factor to overcome the local minimum of the PIDNN. The distinct improvement of the PIDNN control system is proved by simulation results.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125531229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, in this paper, a multipath delay estimation model based on frequency domain phase offset (FDP-MDE) is proposed. And then, a grouped joint time delay estimation algorithm (GJ-TDE) is proposed according to features of the LTE system. Simulation results show that the root mean square error (RMSE) of the GJ-TDE algorithm is 5.5034m smaller than that of the synchronization algorithm under the condition that the signal-to-noise ratio (SNR) is 0dB and the sampling interval is 8.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117007028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is impossible for human to finish the examine because of that the tremendous tubes inside the generator makes its inner space too crowded. In this paper, we introduced a novel designed climbing robot system which is competent to the work. The main part of the robot system is a vehicle which can moves inside the steam generator carrying a PT Arm. Four cameras are installed in the vehicle and PT Arm to send the real time video back for analysis. We built a control panel as the interface for users to control the vehicle and a cabinet as the container of all the processors int the control system.

Conventional algorithms always calculate pixel's local standard deviation in a rectangular area centered to itself, which fail to take the natural traits of the image's content into consideration. The algorithm we propose uses fuzzy clustering to cluster pixels into different types, hence to extract the feature of the image's content. And modify the pixel combing the standard deviation of the cluster it belongs to with the global one, which enables us to more effectively enhance the image's contrast. Experimental results show that the proposed method can improve image's contrast more significantly than the conventional gray level transformation algorithm.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128518423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This project, named \"Bonifica 2.0\", aims at the touristic exploitation of the Pontine territory, a large naturalistic area in the region of Lazio in Italy, configuring mixed routes (waterways, channels and bicycle/pedestrian paths) out of the road network paths and expanding the concept of land sustainable mobility to waterways and coastal lakes that characterize all the Pontine area. The goal is the restoration of historical, archaeological and natural zones in an innovative way and with the use of new technologies and environmentally sustainable means of transportation. A mobility system integrated with the mainland has been studied and will be implemented. The system will allow to manage the fleet and the infrastructures assuring safe routes and the exploitation of historical / cultural sites. Moreover the system will be used as best practice of an Integrated Territorial System of Sustainable Mobility under development in Europe and to be used as a reference case to be proposed and reproduced to other similar areas in the world.

Images acquired in bad weather, such as haze and fog, are seriously degraded by the scatting of the atmosphere, which makes the image color gray, reduces the contrast and make the object features difficult to identify. The bad weather not only lead to the variation of the visual effect of the image, but also to the disadvantage of the post processing to the image, as well as the inconvenience of all kinds of instruments which rely on optical imaging, such as satellite remote sensing system, aerial photo system, outdoor monitoring system and object identification system. That's the reason why they need enhancement and restoration for the improvement of the visual effects and convenience of post processing. This paper sums up the status of image haze removal methods. After that, quantitative and qualitative evaluations of these techniques are presented and the challenges of the existing haze removal method are summarized. Finally, we proposed some expectations to the future research in the field of image haze removal.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114077506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A parallelogram based passive position arm is proposed and detailed analyzed then, and a three spherical joints based end-effector is proposed and detailed analyzed. Hereafter, different lock methods for joints are discussed and evaluated for both passive position arm and end-effector.
