The effectiveness of mobile web is contingent upon many factors. Among them, visual properties such as colors of web content can significantly influence user experience. However, website designers may not be a usability expert or even be aware of color impacts on the perception and experience of users, particularly on those with color vision deficiency (CVD). As a result, using colors that are difficult to distinguish by CVD people within the same web pages could cause significant problems in recognition and comprehension of web content. Existing color adaptation research has focused on regular web but yet to address the unique challenges of mobile web such as limited computing power and battery capacity. To improve the accessibility of mobile web, this research aims to adapt colors in mobile web pages that are non-distinguishable to CVD users while preserving some properties of original colors. In addition to web color replacement, we propose two methods to improve the efficiency of color adaptation to overcome the resource constraint of mobile devices. One method narrows down colors that need adaptation by identifying foreground and background color pairs. The other reduces the computational cost of assessing a set of replacement colors by introducing differential naturalness and differentiability. The effectiveness of the proposed methods was demonstrated with both theoretical proof and experiment results.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114621055","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}

In the MDIS, files are stored in MDIS storage and accessed in place as if they are in conventional DRAM main memory without any duplication between the main memory and secondary storage. The MDIS comprises three components: a virtual accessing adapter (VAA), an array of non-volatile hybrid memory (NVHM), and its associated virtual memory management module. The NVHM can be divided into two spaces-specifically, static and dynamic spaces-to support conventional memory management. Further, the VAA comprises four small buffers that support static and dynamic virtualization according to program execution characteristics. Experimental results show that the read/write load traffics for the proposed MDIS can be reduced by about 73% as compared with the cases of conventional main memory system. In addition, access latency of non-volatile hybrid memory is reduced by 51%.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117126633","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}

Uses for these vehicles include operations in remote areas where access to a structured network such as 3G, 4G, 5G, or Wi-Fi may be unavailable, making reliable communication an issue. Limited battery power of these vehicles is another issue that impairs their ability to perform autonomous duties for extended time periods. We propose a new delay-tolerant-network (DTN) topology that allows the vehicles seamlessly communicate with each other and additional nodes, and a novel autonomous charging system utilizing our network to solve the problem of limited battery power for extended autonomous duties. We designed a cost-effective, heterogeneous, ad-hoc DTN to carry and relay information between robotic vehicles, charging stations and additional nodes, where nodes can collect and store data from each other to relay to additional nodes. Furthermore, we developed an automated charging process, where autonomous robotic vehicles collect, share, and store information about the charging stations they have encountered using our DTN network. When the vehicles need charging, they use the data stored in their memory to autonomously navigate to the charging stations and connect with them using image detection to charge their batteries, eliminating any need for outside intervention. To demonstrate the autonomous charging process, we prototyped two autonomous robotic vehicles controlled by smartphones. These smartphones run a custom Android application we developed to perform wireless communication over DTN using the ZigBee protocol. The vehicles navigate autonomously using GPS and on board ultrasonic distance sensors, and precisely connect to charging stations by using the smartphone camera to detect specific patterns. Additionally, we built a prototype charging station that also acts as a gateway between our DTN and the Internet.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123706171","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}

Thus data from all wireless devices in that network can be gathered, sank, and provided to users via a friendly interface using web pages. These protocols offer limited automation. Much training is required for users to analyse data from different wireless networks. To resolve this issue, recently many researchers are contributing to design and implement an appropriate protocol for the communication between a heterogeneous wireless network and the Internet [1-3]. In this paper, we present a scalable and flexible communication protocol which is designed to work as an interface between the Internet and various wireless networks in a heterogeneous network, to store information and to provide web services to end users. Using web services, users can interact with wireless devices remotely and easily. The current implementation is based on a Linux server. This server uses different communication interfaces to talk to various wireless networks. From these communication interfaces, data is acquired, processed, and stored in the server. Algorithms are developed to analyse data in data processing stage to maximize automation. Meanwhile this server works as a web server and provides web services to remote users. Current studied wireless protocols include ZigBee, Bluetooth, and Wi-Fi. And our communication protocol can be scaled to work with more wireless protocols and developed into a distributed system.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127635083","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 data is also used by various high level applications in automation engineering, decision support, operation planning and scheduling, and measurement and accounting. Due to the increasing security threats and system failures, SCADA data may be compromised, corrupted, or produced by malfunctioned devices/applications. Ensuring a high level of data integrity is critical for the operations of SCADA systems and the supported business functions. In this paper, a data labeling approach is proposed to ensure data integrity in SCADA systems. Essentially, a label records the component information of a data item as well as how the data is generated. This information is used to assess how damage to a component data could result in damage to compound data items and, more importantly, how to detect such damage and correct any affected data. For any compromised data that has been recovered, its label must be updated, called relabeling. We define relabeling strategies and communication models to propagate component updates to all the affected data items to ensure that they can be corrected, thus to maintain data integrity. To our best knowledge, our work is the first of its kind to specifically address data integrity issues in SCADA systems.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121795446","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}
