Yet many of our traditional transportation systems are inadequate to serve the needs of the 21st century. Thus, Intelligent Transportation Systems (ITS) has been proposed as a promising direction to provide innovative services in various modes of transport and traffic management. Researchers have accumulated abundant knowledge for designing ITS systems based on surveys and feedbacks from users and operators. However, the data collected from these manually conducted methods are often incomplete, inaccurate and out-of-date. Thus, based on these data, the applications, correlations and interactions among different forms of transportation are under-exploited [1]. This inefficiency calls for a new architecture, which collaboratively integrates sensing and control aspects in the data processing chain of ITS systems, i.e., data acquisition, data analysis, and data utilization, from multimodal transit systems, e.g., taxicab, bus, and subway, by fully automatic realtime methods. Because of the limited understanding on how to collaboratively interconnect different transit systems for realworld applications, we face an urgent and challenging task to investigate the theory and practice in order to coordinate the sensing and control aspects efficiently and collaboratively. To accomplish this task, this research aims at (i) addressing a fundamental challenge that uniquely defines sensing and control aspects in ITS - heterogeneity, (ii) proposing a design for a multi-level architecture to collaboratively handle different procedures of ITS datasets, and (iii) testing our architecture in one of the largest transportation systems in the world as reference implementation in real-world scenarios.","PeriodicalId":409799,"journal":{"name":"2014 International Conference on Collaboration Technologies and Systems (CTS)","volume":"378 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128357419","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}

Such communities will be able to engage in greater tasks beyond what can be accomplished by individual peers, yet are beneficial to all the peers. These emerging systems will share a variety of resources such as processor cycles, storage capacity, network bandwidth, sensors/actuators, services, middleware, scientific algorithms, and data. Collaborations involving application-specific resources and dynamic quality of service goals will stress current P2P architectures that are designed for best-effort environments with pairwise interactions among nodes with similar resources. Collaborative Peer-to-Peer (P2P) systems require resource discovery solutions to aggregate groups of multi-attribute, dynamic, and distributed resources. Resource and query aware P2P-based multi-attribute resource discovery solutions will be addressed. A distributed caching solution that exploits P2P communities to improve the communitywide and system-wide lookup performance will be presented, with a view to extend it to multi-attribute systems. We analyze the characteristics of resources and queries using data from four real-world systems. A set of mechanisms will be addressed to generate realistic synthetic traces of multi-attribute static and dynamic resources, and range queries, using the statistical behavior learned from real-world datasets. Such traces are useful in large-scale performance studies of resource discovery solutions, job schedulers, etc., not only in collaborative P2P systems, but also in cloud computing.","PeriodicalId":409799,"journal":{"name":"2014 International Conference on Collaboration Technologies and Systems (CTS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134111788","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 has dramatically increased the volume and generation rates of data, which make querying and sharing non-trivial, and render centralized solutions infeasible. Moreover, in many cases this data is naturally distributed or has to be shared across multiple institutions requiring decentralized solutions. In this paper, we present a federation approach that can take advantage of advanced cyber-infrastructure (ACI) by seamlessly and securely interacting with information/data located across geographically distributed resources. We describe and evaluate the establishment of a federated marketplace across resources from UK and US in the context of collaborative research in medical imaging. We show how users from different sites can transparently access to remote data by placing computational requests in the marketplace. Moreover, we evaluate different pricing policies to demonstrate how site providers and users can benefit from such federation.","PeriodicalId":409799,"journal":{"name":"2014 International Conference on Collaboration Technologies and Systems (CTS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121798833","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}

It is an OASIS standard that is now widely used in a variety of applications, particularly those that require inter-operability between AC systems. The language definition includes a precise grammar, syntax, and semantics, and it is both expressive and verbose. This combination of expressive power and verbosity can lead to difficulty in understanding the language's syntax and semantics for both technical and nontechnical users alike. As a result, reducing the difficulty of editing XACML policies has become an intense area of research. In our own work in this area, we previously showed how to render complex XACML conditions using a non-technical display notation and showed that it is easy to use this notation with interactive plain text editors that do not require any technical coding. Although XACML conditions are expressive and flexible, XACML targets are actually the most commonly used XACML language construct. They have an additional level of complexity, especially in version 3.0, due to the fact that the form and kinds of XACML constructs allowed in targets is much more limited. This paper extends our previous work, showing how the same powerful and flexible interactive editing principles can be applied to targets in order to allow users to use natural logic rather than implementation logic. We extend these principles and fully integrate them into our editing tool, easy XACML. This tool is usable by users with no technical knowledge of XACML, thus making XACML totally transparent to the user, while still retaining all of its functionalities and semantics. Our tool thus allows users to focus on policy logic rather than on details of syntax. As a result, the risk of errors in policies is greatly reduced.","PeriodicalId":409799,"journal":{"name":"2014 International Conference on Collaboration Technologies and Systems (CTS)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116077620","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}

Such multi-surface environments introduce the need for effective interaction techniques that enable the transfer of digital content from one device to another, commonly known as cross-device transfer. Utilizing popular existing cross-transfer methods, such as Pick-and-Drop, in a multi-user multi-surface environment, however, require systems that can distinguish between users in order for the environment to accurately know who is transferring what content to what device. Yet, most commercially available digital tabletop systems are not capable of distinguishing between different users. Therefore, existing cross-device transfer methods must be adapted to work in such a user-information limited context. This paper presents a user study comparing the effectiveness of two adapted transfer methods in the context of a strategic digital tabletop card game task. The two transfer methods included a virtual portals-style method, called Bridges, and an adapted Pick-and-Drop method (A-PND). The studied transfer methods both supported the high-levels of card-transfer between private (tablet) and tabletop surfaces required by the game task. Also, participants' reported preferences were equally divided between the two techniques. An in-depth qualitative analysis of the study data revealed that each transfer method provided unique advantages and disadvantages for the game task, which aligned better or worse with different players' personal task goals.","PeriodicalId":409799,"journal":{"name":"2014 International Conference on Collaboration Technologies and Systems (CTS)","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121893413","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}
