As a consequence of the modelling the masonry is divided into macro-elements separated by possible fracture lines which define the starting of probable regions where damage can be localised.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129656417","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}

Efficient visualisation as well as discovery of useful knowledge from these datasets is therefore very challenging and becoming a massive economic need. Data Mining has emerged as the technology to discover hidden knowledge from very large size of data. Furthermore, data mining techniques could be applied to decrease the large size of raw data by retrieving its useful knowledge as representatives. As a consequence, instead of dealing with a large size of raw data, we can use these representatives to visualise or to analyse without losing important information. This paper presents a data reduction technique based on clustering to help analyse very large spatio-temporal data. We also present and discuss preliminary results of this approach.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124981523","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 computational world is becoming massive and needs scalable and efficient systems. Data management is an important stage to accelerate the petabytes processing. Such environment requires scientific work flows to compose and manage those volumetric data sets. Scientific Workflow is different than general workflow. It deals with scheduling, algorithms, data flow, process, operational procedures and specially data intensive systems. The popularity of Software as a Service (SaaS) is due to the feature of multi-tenancy. The study of scientific workflow in the context of multi-tenant cloud orchestration environment provides control flow, data flow, and new requirements of system development and discovery of new services. We explore a framework of scientific workflow for multi-tenant cloud orchestration environment that deals with semantic-based workflow as well as policy-based workflow.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123515534","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}

Traditional approaches use dedicated servers to store information about the whole system and make all the scheduling decisions. Many mechanisms exist for decentralized environments, based on distributing the information in a certain way over a structured overlay network. This usually creates complex relationships between the distribution of the data to be stored and the performance of the system. In this paper, we present a method for resource discovery with the simplicity and power of centralized approaches, designed for decentralized systems formed by non-dedicated resources. We show that it provides a constant look-up latency for frequent resources in the average case, while causing a low overhead and tolerating the levels of churn that are to be expected from non-dedicated resources.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"67 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116603699","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}

If a system to be modeled is domain-specific, developing the simulation software of the system will require domain knowledge about the system as well as understanding the M&S methodology. This paper describes M&S stakeholders and proposes a collaborative work process in the development of domain-specific simulation software. M&S stakeholders are persons with their own professional knowledge: subject matter experts (SME), domain engineers, M&S engineers, platform engineers, and simulation data analysts. The M&S process consists of eight activities from defining modeling objectives to analyzing simulation data, and diverse M&S stakeholders work together in each activity. The M&S process is applied to develop a real-world M&S software development experience in a military domain. Through the proposed collaborative work process, the capabilities of the M&S stakeholders can be utilized maximally by seamlessly separating yet correlating their works.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116901697","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}

CoopSC is a cooperative database caching architecture, which extends the classic semantic caching approach by allowing clients to share their local caches in a cooperative matter. Cache entries of all clients are indexed in a distributed data structure constructed on top of a Peer-to-Peer (P2P) overlay network. This distributed index is used for determining those cache entries that can be used for answering a specific query. Thus, this approach decreases the response time of database queries and the amount of data sent by database server, because the server only answers those parts of queries that are not available in the cooperative cache.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126780135","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 this paper we propose an effective architecture for a low cost system providing localization information. It is based on the deployment of a (very) large number of passive RFIDs spared inside the cultural area. As shown in this paper, due to the adoption of smart tagged RFIDs tapes the setup and maintenance of the system is greatly simplified independently of the area (indoor and/or outdoor) where the localization system is deployed. System performances are analyzed by considering a study case. Evaluation is carried out in terms of the achievable accuracy in the position estimate and the costs of the RFID part of the system. Finally, a discussion on the additional wireless traffic required for transporting information for localization to the central (multimedia) server, is presented. Accuracy below one meter can be theoretically achieved by properly selecting the density of RFIDs e.g. the number of smart tapes and the RFIDs' distance on the tape.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129650209","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}

On the one hand, managers urge to revise their business model, in order to adapt it to the changes of the external environment and of the competitive scenario. On the other hand, exogenous shocks usually affect collaboration with other players on the market. Such strategies as outsourcing, consortia, joint-ventures, during a crisis, can be used to face the lower financial resources available for the enterprises. Though, if the shock is subtle, sometimes enterprises don’t promptly react, due to distorted or delayed human perception. In this paper we show, by means of a computational model, that even a small percentage of slow-reacting (or biased) enterprises can determine a sub-optimal aggregate behavior when facing a negative exogenous conjuncture.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123720011","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}

At the same time, concentration of vast amount of personal information within a single administrative domain causes critical privacy concerns.

Our system exploits trust relationships in the social network for decentralized storage of OSN profiles and their content. By taking users' geographical locations and online time statistics into account, it also addresses availability and storage performance issues. We finally advocate indexing of social network content and present an approach for indexing in a privacy-preserving manner.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117153327","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}
