Nowadays wireless applications are widespread, and the demand for smart antenna technology grows exponentially. Although there are a large variety of effective algorithms to control antennas, they lack in the requirements of the next generation smart devices for industrial and societal applications which demand integration in compact, low cost and low power architectures. In this work we present a...
Some numerical results about the use of a Reduced Order Model to map currents to their radiated field in the presence of a scatterer are shown for antenna design and placement.
Cloud technologies are still characterized by critical issues, which pose specific challenges for application developers and operators. In particular cloud application-level and infrastructure-level are completely decoupled both in the development and runtime phases leading in poor QoS cloud services. Main issues related to the optimize the use of the hardware resources are partially solve with virtualization...
Particularly in scientific community the size of digital data to be stored is ramping up. For those application characterized by very dynamic workloads is difficult to estimate the real size of storage to be allocated and avoid over-provisioning, also in extremely elastic environments as cloud computing. DAViS (Dynamic Allocation of Virtual Storage) is a prototype of a system for dynamically providing...
Cloud computing is a convenient, on demand, model which relies on shared pool of computing resources that can be rapidly provisioned and needs minimal management effort. As cloud computing obtains popularity nowadays, customers are looking for cloud solutions to adapt their organization's requirements. The more changes occur, customers are trying to decide what kind of cloud they are going to choose...
This paper deals with the implementation of an hybrid cloud computing infrastructure in support of an EM virtual prototyping system with applications in industry. The solver use Compressive Domain Decomposition (DD) for Integral Equation methods. The DD paradigm is analyzed in terms of overall computational requirements in association with fast factorizations and will be explained benefits and computational...
The new Italian GPS receiver for Radio Occultation has been launched from Satish Dhawan Space Center (Sriharikota, India) on board of the Indian Remote Sensing OCEANSAT-2 satellite. The Italian Space Agency has established a set of Italian universities and research centers to develop an infrastructure based on hybrid architecture, that is implemented for the overall processing Radio Occultation chain...
Computational Electromagnetics (CEM) is a technique used to simulate the interaction of electromagnetic fields with structures in a particular environment. The geometries to analyze are typically very complexes and they could be simulated with a CAD model, that can include a fine level of details. This is reflected in a higher computational effort that must be faced by high performances infrastructures...
In this paper we describe this new scenario for the radio occultation data processing, which is based to the use of distributed system architecture. In particular, we describe our approach based on using a grid computing system in order to decrease the calculation of RO time and to increase the flexibility and reliability of the system. We want to focus the attention of the reader on how we managed...
