This work aims to present the VULCAIN mission study to design and characterize a new CubeSat mission for Earth Observation dedicated to volcanoes. The project is supervised by the European Space Agency (ESA) and involves six Italian partners. The project involves the construction of two 12U nanosatellites flying in formation. Each satellite embarks two instruments onboard: a COTS VIS-NIR camera and a multispectral thermal camera with four channels in the 8-12 µm spectral range. The main scientific objectives are to measure the Land Surface Temperature (LST) and to combine VIS-TIR data to enhance the observation on volcanic areas by adding morphological analysis.

In this paper, an automatic processing chain, fully de-veloped in C++, for the generation of simplified Synthetic Aperture Radar (SAR) images of large urban scenarios is presented. The proposed method makes use of open GIS data and an open-source simulation technique based on ray tracing. The main novelties refer to: 1) the integration of a method for generating Three-Dimensional (3D) models of almost any arbitrary place on Earth, including in the model land cover information of the scene, 2) the possibility of setting the SAR parameters for the creation of images acquired under different geometries (e.g. satel-lite and airborne with arbitrary view (or look) angles), and 3) the ability to have at the end of the processing chain a geo-referenced image for comparisons with other types of data. The authors strongly believe that this pa-per can be of wide interest to researchers in the field of Remote Sensing (RS).

We extend to natural deduction the approach of Linear Nested Sequents and of 2-Sequents. Formulas are decorated with a spatial coordinate, which allows a formulation of formal systems in the original spirit of natural deduction: only one introduction and one elimination rule per connective, no additional (structural) rule, no explicit reference to the accessibility relation of the intended Kripke models. We give systems for the normal modal logics from K to S4. For the intuitionistic versions of the systems, we define proof reduction, and prove proof normalization, thus obtaining a syntactical proof of consistency. For logics K and K4 we use existence predicates (à la Scott) for formulating sound deduction rules.

While IT integration is recognised as an important capability, the mechanisms through which it creates value and the contingencies that delimit its effectiveness are unclear – particularly, in the case of firms that deliver solutions embodying both products and services. We focus on IT vendors to investigate the effectiveness of IT integration capability with respect to three aspects of IT solution offerings: breadth, modularity and customisation. We find a complementarity effect between IT integration capability and management of the IT offer strategy: IT integration is fundamental regardless of whether the firm relies on customisation or a broad set of heterogeneous knowledge bases. However, when IT vendors adopt a modular design strategy, IT integration is made redundant and can be counterproductive.

We give a sound and complete labelled natural deduction system for a bundled branching temporal logic, namely the until-free version of BCTL*. The logic BCTL* is obtained by referring to a more general semantics than that of CTL*, where we only require that the set of paths in a model is closed under taking suffixes (i.e. is suffix-closed) and is closed under putting together a finite prefix of one path with the suffix of any other path beginning at the same state where the prefix ends (i.e. is fusion-closed). In other words, this logic does not enjoy the so-called limit-closure property of the standard CTL* validity semantics. We give both a classical and an intuitionistic version of our labelled natural deduction system for the until-free version of BCTL*, and carry out a proof-theoretical analysis of the intuitionistic system: we prove that derivations reduce to a normal form, which allows us to give a purely syntactical proof of consistency (for both the intuitionistic and classical versions) of the deduction system.

In this paper we present the Pilot Project PRIMI, designed to provide information on marine oil spills, and its validation campaign, held in august 2009, conducted with the oceanography ship Urania. During the experiment CosmoSkymed has provided an extraordinary contribution supplying almost any day images over the area inspected by the ship and in some cases also images requested with short notice.

High resolution Cosmo-SkyMed SAR images are used for oil spill detection and ship identification on the Mediterranean Sea, in the framework of PRIMI Pilot Project currently developed by Italian Space Agency (ASI). The system consists of four components, two of them devoted to the analysis of the SAR and Optical satellites images for the slicks detection, an oil spill forecast subsystem and a central archive that provides web-gis services; a preliminary version of the system is already operational. Besides the slicks relevant information and detected ships on the analyzed scene, the system also provides meteorological and oceanographic information. The architecture of the system, the operational scenario and the preliminary results are presented.

We study a measurement-free, untyped λ-calculus with quantum data and classical control. This work arises from previous proposals by Selinger and Valiron, and Van Tonder. We focus on operational and expressiveness issues, rather than (denotational) semantics. We prove subject reduction and confluence, and a standardisation theorem. Moreover, we prove the computational equivalence of the proposed calculus with a suitable class of quantum circuit families.

A dual infrared system to assist a driver in bad visibility conditions is studied. The problem of selecting the best multiresolution-based image fusion technique is addressed with reference to automotive scenarios. A new method for objective evaluation of multisensor image fusion strategies is presented for the optimal design of the fusion process. Multiresolution-based fusion methodologies are compared, and experimental results obtained from a prototype dual infrared camera system are shown and analyzed. Numerical results, in terms of the quality of the fused images and of the computational load, are presented and discussed. The effectiveness of the dual infrared system in urban and extraurban automotive scenarios is illustrated with a number of examples.

The concept of syntactical duality is central in logic. In particular, the duality defined by classical negation, or more syntactically by left and right in sequents, has been widely used to relate logic and computations. We study the proof/test duality proposed by Girard in his 1999 paper on the meaning of logical rules. In detail, starting from the notion of “test” proposed by Girard, we develop a notion of test for intuitionistic logic and we give a complete deductive system whose computational interpretation is the target language of the call-by-value and call-by-name continuation passing style translations.

Video sequence stabilization permits an accurate analysis of the video originate from sources as video cameras or IR sensors. In fact, a system of video stabilization allows the availability of aligned image sequences and, consequently, to improve the operator analysis of the scenario. In this paper different image processing methods are analyzed to remove the camera unwanted motions and reconstruct a stabilized sequence for real time applications. In particular three methodologies are compared in term of computational load and of the expected scenarios to determine the best strategies to be applied in a real time system.

In this paper a methodology for fusion quality evaluation is proposed in the case of many source images to be fused in a single one. Various multiresolution fusion methodologies are compared, and experimental results are shown. Numerical results, in terms of quality of the fused images and of computational load, are presented and discussed with reference to avionic scenarios.

Abstract We present a sequent calculus for the modal logic S4, and building on some relevant features of this system (the absence of contraction rules and the confinement of weakenings into axioms and modal rules) we show how S4 can easily be translated into full prepositional linear logic, extending the Grishin-Ono translation of classical logic into linear logic. The translation introduces linear modalities (exponentials) only in correspondence with S4 modalities. We discuss the complexity of the decision problem for several classes of linear formulas naturally arising from the proposed translations.

In this work we propose a study of intuitionistic minimal modal logics by means of a new calculus called intuitionistic 2-sequent calculus. We show that the proposed calculus has an associated natural deduction system. We compare the 2-sequent calculus and the natural deduction system.
