Accordingly, viral marketing which aimed to promote products in social network received more and more attention. The Network Diffusion model describes how information or influence is propagated in a social network. It is of great importance to the viral marketing/influence maximization problem. However, there are two challenges: first, how to build the diffusion model so as to simulate the diffusion process better, and second, how improve the efficiency of the diffusion model so that it can be applied to more scalable viral marketing problems. To tackle these two problems, we proposed a Cellular Automaton based Network Diffusion (CAND) model. We also proved that the CAND model is equivalent to the Linear Threshold (LT) model under certain conditions. Moreover, the model is realized and a speed up method is used so as to improve the efficiency of the model. Experiments show that compared with the LT model, our model is much more efficient on four real life social network datasets, indicating a better scalability for Viral Marketing.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115504109","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}

Given such an arrangement it is possible to access sensor data and control actuators remotely. Furthermore such data may be combined with data from other sources - e.g. with data that is contained in the Web - or operated on by cloud based services to create applications far richer than can be provided by isolated embedded systems [2,3]. This is the vision of the Internet of Things. We present a cloud-compatible open source controller and an extensible API, hereafter referred to as `IoTCloud', which enables developers to create scalable high performance IoT and sensor-centric applications. The IoTCloud software is written in Java and built on popular open source packages such as Apache Active MQ [4] and JBoss Netty [5]. We present an overview of the IoT Cloud architecture and describe its developer API. Next we introduce the FutureGrid - a geographically distributed and heterogeneous cloud test-bed [6,7] - used in our experiments. Our preliminary results indicate that a distributed cloud infrastructure like the FutureGrid coupled with our flexible IoTCloud framework is an environment suitable for the study and development of IoT and sensor-centric applications. We also report on our initial study of certain measured characteristics of an IoTCloud application running on the FutureGrid. We conclude by inviting interested parties to use the IoTCloud to create their own IoT applications or contribute to its further development.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115876532","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}

For unmanned platforms to reach their full potential, users must be able to exert supervisory control over those platforms. This requires more effective means of communication in both directions, including high-level commands given to the vehicle and meaningful feedback to the user. Our aim is to reduce the training requirements and workload needed to interact with unmanned systems effectively and to raise the level of user interaction with these systems so that supervisory control is possible. In this paper we describe an intelligent user interface, called the Smart Interaction Device (SID) that facilitates a dialogue between the user and the unmanned platform. SID works with the user to understand the user's intent, including asking any clarification questions. Once an understanding is established, SID translates that intent into the language of the platform. SID also monitors the platform's progress in order to give feedback to the user about status or problems that arise. We have incorporated multiple input modalities, including speech, gesture, and sketch as natural ways for a user to communicate with unmanned platforms. SID also provides multiple modes of feedback, including graphics, video and speech. We describe SID's architecture and some examples of its application in different domains.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129112031","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}

Each group is independent of all others and adheres to the formal semantics of Group-Centric Secure Information Sharing models (g-SIS) [2], [4]. Motivated by [3], in this paper, we develop a model for group-centric collaboration in which an organization forms groups to collaborate with outside consultants on specific projects. A core principle is that such outsiders cannot fit in the existing organizational access control structure as they are not “true insiders” but rather “expedient insiders.” In our proposed model, each group duplicates the organizational access control structure in an identical but separate copy—initially without any assignment of users or objects. The group is then populated and maintained by bringing selected true insiders, expedient insiders, and objects together to enable collaboration. The formal model consists of administrative and operational parts covering the complete life-cycle. While the general concepts are applicable regardless of the specific models used for the organizational access control structure, to be concrete we consider the specific case of multilevel systems that enforce lattice-based access control [7].","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130862439","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}
