A Knowledge Base Driven Solution for Smart Cloud Management

This paper presents a Smart Cloud solution based on a Knowledge Base, KB, with the aim of modeling cloud resources, Service Level Agreements and their evolution, while enabling the reasoning on cloud structures and implementing strategies of efficient smart cloud management and intelligence. The solution proposed is composed of Smart Cloud Engine, SCE, the Knowledge Base, KB, and the Supervisor and Monitoring module for data acquisition. It can be easily integrated with any cloud configuration manager, cloud orchestra or, and monitoring tool, since the connections with these tools are performed by using REST calls and XML files.

Evaluating a flexible architecture for distributed control

Proceedings Fifth IEEE International Conference on Engineering of Complex Computer Systems (ICECCS'99) (Cat. No.PR00434)

These activities have to be synchronized with several other simpler activities along the pipeline. Computerized numerical controls for such systems have to be flexible and strongly expandable and reusable since pipelines are frequently reconfigured to realize differently arranged pipelines with different technical requirements. The assessment of such a flexible architecture is presented, on the basis of which the building of flexible distributed controls for pipelines is possible. The architecture has been defined in the ESPRIT HPCN (High Performance Computer Networking) project MUPAAC (Multi Processor Architecture for Automatic Control). MUPAAC architecture and prototype has been assessed in order to identify the most important performance indexes

IPR Tools for Content Aggregators

The IPR management systems can be classified in Digital Rights Management (DRM) systems allowing to control ‘all’ the possible different uses of a digital content (e.g. distribution, enhancement, adaptation) and Conditional Access Systems (CAS) allowing to control only the access to the digital resource that is provided with some encryption. Those solutions are typically suitable to address the digital content distribution and commerce and less suitable for managing cultural heritage content and IPR. To this end, in ECLAP a model and tools have been defined, while starting from the conceptual and legal aspects inherited from IPR, DRM standards such as MPEG-21 and ODRL. In this poster we describe the system adopted in the European Collected Library of Artistic Performance, ECLAP, to manage, publish and distribute digital content taking into account the problems connected to the IPR of cultural heritage cross media content on Performing Arts domain. The model and solution adopted can be applied to a large range of cultural content, also in relationship with Europeana galaxy of content. According to ECLAP workflow, metadata sets are sent to Europeana only after that: i) they have been enriched and linked to a reachable digital resource; ii) when the IPR issues have been correctly defined. Therefore, a suitable workflow for metadata ingestion, quality improvement, metadata enrichment, and IPR solution have been set up and put in place. The main problems related to the IPR management in ECLAP, as well as in many cultural heritage communities playing the role of content aggregator and content providers, are: i) inconsistent rights with respect to the objects; ii) definition of coherent IPR Models according to the contract and right owned; iii) Application of IPR Models and enforcement of them on the distribution portal and towards Europeana; iv) IPR Model&amp;#39;s Additional Conditions such as: student access, different access for devices, time, location, etc. The main aim of IPR model and wizard was to help Content Partners (CPs) to avoid the production of associated permissions and right models to objects that would be incoherent in terms of: conflicts among rights, incoherent rights and contract, conflict among rights and what is defined in the Europeana rights. Moreover, the inconsistencies can be due to the definition of limitations that cannot be enforced to a given context and/or that are not legally valid. Given the diversity of CPs and of the related needs on their contents, a general and flexible IPR model. The IPR model proposed contains at least: a model name, a description, a permission set, a license, a publisher, additional conditions, a reference to the content partners license page, etc. In ECLAP, many different set of permissions on the contents are available and take into account both ECLAP Content Providers’ needs, user’s roles and profiles. Permissions managed on the ECLAP can be referred to the following aspects: i) access to the content; ii) user device; iii) content resolution; iv) user kind. An IPR Wizard, to guide the CPs on assigning permissions on their contents has been realized, and it is largely used by more than 35 partners in Europe. As of January 2013 there are in use 100 IPR models, 30 are restrictive not public models while 19 are public models over 170000 contents. The IPR Wizard models and tools are used as a basis of IPR solutions on other portals.

ABSTRACT

Verification of external specifications of reactive systems

IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2000

The external specification can be defined during the early stages of the system development and can be very useful for: checking the class/system/subsystem requirements; checking the system composition; evaluating costs of reuse; defining validated reference requirements, histories, and traces for the final validation. This paper presents a collection of criteria in order to formally verify the external specification of reactive systems/subsystems. The verification criteria are grounded on the Tempo Reale Object-oriented Language (TROL) specification model for real-time systems. In TROL, the external specification is expressed in terms of ports and clauses with temporal constraints. The goal of the verification criteria presented is to check the completeness and consistency of the external specification with special attention to temporal constraints. These criteria can be applied to other real-time specification models and have been enforced in the Tool Object Oriented Machine State (TOOMS) tool. A practical example illustrates the verification process that embodies these criteria.

The analysis of user behavior on social network is fundamental to tune services and stimulate the network growth. This is even more relevant for best practice collaborative networks where details about collaboration may lead to understand the effective activities and role of people in the several groups. In this paper, a set of metrics for analyzing user behavior related to downloads and other aspects on the best practice network is presented. The metrics and the work presented have been applied, and are currently active, as administrative tools for the Mobile Medicine best practice network.
