These requirements are usually facilitated by X.509 und Private-Key Infrastructures (PKI) and proxy certificates. Proxy certificates, however, can be obtained and abused by a malicious third party. There is currently no method for end users to detect such abuse. We have designed a solution that enables a thorough auditing of Grid proxy usage in Globus-based Grids and implemented a service that accepts auditing information via a web service interface and saves them to a back-end database. We introduce modifications to the Grid Security Infrastructure that allow sending audit trails from within Globus components if the user desires to track credential usage. A web-based front-end shows all logged information. With our approach, expert users can now closely monitor how their credentials are used after job submission. This will help build trust in Grid infrastructures and delegated authentication and authorization.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131406875","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 earlier work, we have explored dynamic reconfiguration, distributed management and a web services interface for remote deployment and control of cloud-based streams. Here, we look at aspects of remote interaction between a ProActive distributed active object system and the University of Chicago Nimbus cloud, showing that it is a useful environment in which to explore effects of distribution on latency, and commenting on problems of interaction through a firewall. We summarize some performance results of stream processing in the Nimbus cloud, especially our mechanisms for latency tolerance in remote interaction, with network measurements to show their effectiveness. The major contribution of this paper is to look at aspects of scheduling our stream components in a cloud based computation, focusing on criteria for initial deployment of the stream on cloud resources, outlining attributes of cloud resources that can sensibly be used in making scheduling decisions, and working towards a \"cost model\" suitable for use by economic scheduling heuristics. For this, we make use of Grid-bus; we introduce our model of interaction with it, our preliminary implementation, and demonstration of the use of Gridbus for deployment.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133120355","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}

Therefore, our research challenge is two-fold: (a) to define what Place is by pointing to ways in which emotion states can be observed and are bound together within a social network; and (b) to develop a visual representation that provides the framework for representing patterns of emotion states associated to this Place. Towards this end, this paper will demonstrate our first results on the analysis of the correspondence obtained in the archive of Simo¿n Ruiz that adds up to more than 50,000 documents, which were collected from a long list of sources during four decades.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115292229","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}

All surnames in the census were geo-referenced to the 662 Registration Districts listed. The districts' surname compositions were compared using the Lasker Distance calculation. The resulting similarity values, assigned to each district, were grouped according to Ward's hierarchical clustering. By mapping the cluster allocations a clear regionality, characterised by a high spatial autocorrelation value, emerges that closely matches the historical attempts to establish the surname regions in 19th Century Britain. As one of the first studies of this kind to utilise a complete population register for 1881, with results aligned to historical interpretations, one can think of the maps presented here as a baseline for the regionality of surnames in Great Britain, against which the effects of more recent migrations can be compared.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125646131","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 input data, the algorithms, and the output data can be represented by nodes in a lineage graph; the child node (the output data) is connected by uni-directional arcs to the parent nodes (the inputs and the algorithm). Lineage graphs provide reproducibility as well as navigation back to original inputs and algorithms. Storage system technologies can be tremendously helpful in the storage and management of data lineage information. Recent developments in the storage industry can assist in the creation of lineage graphs. Object-addressable storage (OAS) systems can unify data with its lineage; the eXtensible Access Method (XAM) can serve as an industry standard access method for manipulating these united objects. Object-addressable storage systems can be mounted as cloud storage devices. These devices are capable of providing lineage functionality to provenance-aware applications.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115790155","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}

Since that date artists have been exploring the use of GPS as an expressive and social medium. This paper focuses upon the capacity for locative media to support the social discussion of place. Beginning with the work of established artists and researchers who use GPS, the authors highlight a tendency in the works to engage with individuals in the field, but to discuss social aspects at a distance. In attempting to allow social reflection upon a place in ‘real-time’, the authors have developed a novel technical and conceptual twist on the use of GPS data that allows them to sustain live spatial/social dialogues.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126924646","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}
