In our implementation, clustered server architecture for high throughput data ingestion is proposed with regard to following factors: receiving stream data, i.e., machine logs, from a set of milling machines, storing them in a centralized messaging queue, and sinking to external systems with ease. Especially, we leverage the power of the open sources frameworks, Apache Kafka, Apache Hadoop File System and Apache Flume to cope with the data streams from a large number of machines in the factory floors. As this is an on-going study, we only illustrate our implementation details with structural diagrams, but exclude the theoretical study and the performance evaluation results in this paper.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130175603","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, there are serious secure threats exit such as key-logger attack that leaks key input values of virtual keyboards. Since the smart-phone provides limited virtual keyboards due to its small screen size, it is more vulnerable for such attacks compared to personal computers (PCs). In this paper, we propose a solution for this problem. Our approach has a unique feature to improve security of the keyboard while maintaining high accessibility against existing solutions. Moreover, we can also apply it to various mobile devices with small screens due to its flexibility in terms of the size.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"122 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129503604","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, widely available GPS systems suffer from precision degradation brought about by satellite availability and multipath signals. This is especially true in urban canyons, where buildings often obstruct and reflect GPS signals. In order to ignore or rectify multipath signals, previous studies have taken into account building geometries. However, computing and retrieving building geometries for entire urban areas is still impractical for most on-board localization systems. The proposed system exploits the fact that most Public Utility Buses are constrained to a single route, enabling the system to store building geometries along the entire bus route a priori. Position corrections are computed from known satellite positions and multipath signal computations on buildings along the route. A centimeter-level accurate GPS system is presented without the need for more expensive equipment.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131326791","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 half-duplex two-way relay is adopted to establish the communication between both RF and FSO links. Under this scenario, the associated end-to-end statistical features of the system are derived. They are then used for calculating outage and average symbol error rate (ASER) of M-ary phase shift keying (MPSK). Furthermore, we characterize the asymptotic behaviors and diversity orders for both outage and ASER at high signal-to-noise ratio (SNR). It is observed that the diversity orders depend on the severity of PE, which equals to 1/2 for weak PE and equals to g2/2 under strong PE with g being the PE severity. Finally, simulation results confirm the accuracy of the theoretical analysis and observations.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129150962","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 machines are usually either probabilistic and neural networks consisting of one layer. In this propose we use deeper machines (DNN, DBN and GB-DBN) to increase the estimation accuracy and reduce generalization error on dynamic indoor environment. Also we investigated the impact of pre-training algorithm on fingerprinting indoor location systems. Experimental results demonstrate that deep models provide an efficient generalization performance on indoor environments. They have the disadvantage that demand high processing resources when they are trained on off-line phase, however, deep models are swift to predict during on-line phase.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134011852","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}
