SRSSRIF is combined with square root filter and fused the spherical simplex radial rule (SSRR) into information filter. We utilize the rule of spherical simplex radial to choose the integral points and the computation of the corresponding weights. The efficiency of the new algorithm is demonstrated with a 3D Lorenz system and a two permanent magnet synchronous motor. Simulation results indicated that SRSSRIF can gain preferable precision compared with extended information filter (EIF) and square root unscented information filter (SRUIF) for single or multi-sensors system.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399075","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}

The algorithm directly extracts the specific video characteristics from the HEVC bitstream, and establishes the mathematical model between the video characteristics and the final video quality through linear regression, so as to realize the objective evaluation of the video quality. The algorithm extracts three video features: the quantization parameters of the measurement compression damage, the number of CTU of different sizes (8×8 & 32×32) and the numbers of the SAO blocks. The experimental results show that the objective evaluation results obtained based on these three parameters have good correlation with the results of subjective experiment results. In addition, because the algorithm only needs to rely on the stream and the coding parameters can be reliable and rapid evaluated, can be widely used in the real-time terminal occasions.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129448734","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}

Exposure to the fine particulate matters (PMs) will harm the human health and even cause irreversible damages, which calls for effective monitoring methods. It is necessary to bring in a monitoring platform with sufficient mobility for the places where monitoring stations are not convenient to install. A mobile and portable monitoring platform based on unmanned aerial vehicle (UAV) is developed by combining promoted sensor board and specific communication module in this paper. Moreover, the air quality monitored by UAV-platform will generate important information for the controlling of indoor air quality for indoor environment in the buildings. To meet the indoor inhabitants' requirements of health and comfort, a fuzzy control method is proposed in this paper to control the actuators of air cleaner and ventilator. With a good coordination, an intelligent environment which meets the comfort level with good indoor air quality (IAQ) can be achieved.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128566769","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}

Anomaly detection of Logo image is an important quality control task in the intelligent manufacture. In real applications, there are not enough negative samples in the production line for us to study their difference from normal samples. In this paper, we propose an unsupervised learning method based on convolutional autoencoder (CAE) to generate the template of sample and detect the abnormal information through comparing test images with the adaptive template. Firstly, several methods of data augmentation are introduced to expand the scale of positive samples, aiming to improve the performance of CAE. Secondly, the topology of proposed CAE model is introduced. Thirdly, we introduce the image processing methods to detect and locate the abnormal information in the Logo image. A series of experiments on three group of different Logo image have shown that the method we proposed can effectively detect most of the anomalies in the image and achieve the average accuracy of 98.9%.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"931-932 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127170437","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}

The South China Sea airspace is also experiencing significant air traffic growth. The rapid growth may induce the deficiency of airspace capacity and cause more problems such as flight congestion and delay. Europe and America have conducted research and implemented particular concepts to ease the situation of high demand. In order to improve the capacity usage of efficiency of the South China Sea airspace, the concepts and technology with the potential of boosting the airspace development are taken into consideration. This paper describes these concepts and the results of preliminary activities to investigate the feasibility of these concepts while keeping safety level in South China Sea airspace.

However, most of the previous research did not consider the imperfect state information of the AR candidate sufficiently since it is hard to be formulated. This shortage limited the application of the existing research in practice. In order to solve this problem, an AR selective (ARS) strategy is proposed and analyzed.

The SIN matching solution combined with single point and neighboring triple points mapping strategy is presented as a core of the matching algorithm. By means of repeated operations, an incremental verifying tool for estimating the quality of fingerprints is successfully built.
