The engineering of complex production automation systems involves experts from several backgrounds, such as mechanical, electrical, and software engineering. The production automation expert knowledge is embedded in their tools and data models, which are, unfortunately, insufficiently integrated across the expert disciplines, due to semantically heterogeneous data structures and terminologies. Traditional...
Open source software teams routinely develop complex software products in frequent-release settings with rather lightweight processes and project documentation. In this con-text project a major challenge for data collection is how to extract the relevant project management knowledge effectively and efficiently from a wide range of software project data sources, such as artifact versions, bug reports,...
Forecasting applications on the stock market attract much interest from researchers in the artificial intelligence field. The problem tackled in this study concerns predicting the direction of change of stock price indices, formulated in terms of binary classification. We use gene expression programming to evolve pools of binary classifiers and investigate several approaches to construct ensembles...
GPS - Radio Occultation is a remote sensing technique aim to characterize some atmospheric parameters. It is based on the analysis of the time evolution measurable on the GPS signal received on-board a Low Earth Orbit satellite. Result of analysis is the atmospheric refractivity profile which, in turn, can be used to characterize temperature, pressure and humidity profiles. This paper present the...
Field workforces have to implement day-to-day control decisions to keep the large scale real-world systems (e. g. Water Distribution Systems) operational. However, existing customized Decision Support Tools (DSTs) for field workforces operate on static and predefined datasets, available in the workers' devices. This results in planning control actions that may appear safe in the local context but...
The paper deals with how a developing country like Iran can prevent socio-economic impacts of demographic and disability transition. This period started between 1991 and 1996 with a rapid decline of fertility and mortality rates and still continues today. This demographic stage constitutes the window or bonus of the best opportunity for Iranian policy makers to do their plan for rapid aging of population...
Earth Science data and particularly the satellite images supplies important information on status and dynamics of earth covering vegetation. The development of environment applications is a challenge for Grid technologies and software development methodologies. This paper exemplifies and experiments the development of the GreenView application by the Grid Application Development Methodology. The paper...
In this paper, our research objective is to develop a database virtualization technique so that data analysts or other users who apply data mining methods to their jobs can use all ubiquitous databases in the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet databases and data cleansing works. In this study,...
The shared data programming model is an attractive grid programming alternative to message passing solutions. This paper addresses type related improvements to a shared data grid programming model, by taking advantage of particular interactions patterns and object semantics which result in a broader set of specialized objects. We present analysis aspects of GUN, a grid service layer solution for shared...
One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data-mechanisms; furthermore in the last years, the Service-Oriented Architecture...
The term Enterprise 2.0 applies to the use of Web 2.0 technologies as a support for business activities within the organizations. These technologies are exploited to foster inter-persons collaboration, information exchange and knowledge sharing, also outside the organization, to establish relationships based on conversational modalities rather than on traditional business communication. The vision...
