Development of Grid e-Infrastructure in South-Eastern Europe
Over the period of 6 years and three phases, the SEE-GRID programme has
established a strong regional human network in the area of distributed
scientific computing and has set up a powerful regional Grid infrastructure. It
attracted a number of user communities and applications from diverse fields
from countries throughout the South-Eastern Europe. From the infrastructure
point view, the first project phase has established a pilot Grid infrastructure
with more than 20 resource centers in 11 countries. During the subsequent two
phases of the project, the infrastructure has grown to currently 55 resource
centers with more than 6600 CPUs and 750 TBs of disk storage, distributed in 16
participating countries. Inclusion of new resource centers to the existing
infrastructure, as well as a support to new user communities, has demanded
setup of regionally distributed core services, development of new monitoring
and operational tools, and close collaboration of all partner institution in
managing such a complex infrastructure. In this paper we give an overview of
the development and current status of SEE-GRID regional infrastructure and
describe its transition to the NGI-based Grid model in EGI, with the strong SEE
regional collaboration.Comment: 22 pages, 12 figures, 4 table

Framework for collaborative knowledge management in organizations
Nowadays organizations have been pushed to speed up the rate of industrial transformation to high value products and services. The capability to agilely respond to new market demands became a strategic pillar for innovation, and knowledge management could support organizations to achieve that goal. However, current knowledge management approaches tend to be over complex or too academic, with interfaces difficult to manage, even more if cooperative handling is required. Nevertheless, in an ideal framework, both tacit and explicit knowledge management should be addressed to achieve knowledge handling with precise and semantically meaningful definitions. Moreover, with the increase of Internet usage, the amount of available information explodes. It leads to the observed progress in the creation of mechanisms to retrieve useful knowledge from the huge existent amount of information sources. However, a same knowledge representation of a thing could mean differently to different people and applications.
Contributing towards this direction, this thesis proposes a framework capable of gathering the knowledge held by domain experts and domain sources through a knowledge management system and transform it into explicit ontologies. This enables to build tools with advanced reasoning capacities with the aim to support enterprises decision-making processes. The author also intends to address the problem of knowledge transference within an among organizations. This will be done through a module (part of the proposed framework) for domain’s lexicon establishment which purpose is to represent and unify the understanding of the domain’s used semantic
Community-based mentoring and innovating through Web 2.0
The rise of social software, often termed Web 2.0, has resulted in heightened awareness of the opportunities for creative and innovative approaches to learning that are afforded by network technologies. Social software platforms and social networking technologies have become part of the learning landscape both for those who learn formally within institutions, and for those who learn informally via emergent web-based learning communities. As collaborative online learning becomes a reality, new skills in communication and collaboration are required in order to use new technologies effectively, develop real digital literacy and other 21st century skills
An Innovative, Open, Interoperable Citizen Engagement Cloud Platform for Smart Government and Users' Interaction
This paper introduces an open, interoperable, and cloud-computing-based
citizen engagement platform for the management of administrative processes of
public administrations, which also increases the engagement of citizens. The
citizen engagement platform is the outcome of a 3-year Italian national project
called PRISMA (Interoperable cloud platforms for smart government). The aim of
the project is to constitute a new model of digital ecosystem that can support
and enable new methods of interaction among public administrations, citizens,
companies, and other stakeholders surrounding cities. The platform has been
defined by the media as a flexible (enable the addition of any kind of
application or service) and open (enable access to open services) Italian
"cloud" that allows public administrations to access to a vast knowledge base
represented as linked open data to be reused by a stakeholder community with
the aim of developing new applications ("Cloud Apps") tailored to the specific
needs of citizens. The platform has been used by Catania and Syracuse
municipalities, two of the main cities of southern Italy, located in the
Sicilian region. The fully adoption of the platform is rapidly spreading around
the whole region (local developers have already used available application
programming interfaces (APIs) to create additional services for citizens and
administrations) to such an extent that other provinces of Sicily and Italy in
general expressed their interest for its usage. The platform is available
online and, as mentioned above, is open source and provides APIs for full
exploitation.Comment: 23 pages, 7 figures, journal pape
Content Management System for Personally Driven Web Site
The goal of the project was to develop a simple content management system that could
be easily used both as a standalone web application and as a part of a more complex
system. The application was supposed to consist of several key modules: commentary
engine, search engine, navigation system and authentication system.
To create a content management system the implementations of the most common
design patterns provided by PHP Zend Framework were used. The application was
developed and tested on Ubuntu Linux with Apache web server and MySQL database
server.
The final version of the project represented a content management system with a
navigation system based on item categorization. The application consisted of multiple
classes: the ones provided by Zend Framework and the ones created to fulfill
application-specific requirements. The system extensively used the benefits of object
oriented programming and the model-view-controller design pattern.
The results of the project allowed making several conclusions. First, although it is faster
to develop the application using the agile programming model, such a technique leads to
less optimized code then, if the design of the application was supported by a unified
modeling language. Second, object-oriented programming provides the application with
a high level of reusability and also makes it possible to employ only certain parts of the
software
