A study of the retrieval sea surface roughness using Global Navigation Satellite System‐Reflectometry (GNSS‐R) from satellite is presented. Delay‐Doppler Maps (DDMs) SSTL UK‐DMC are analyzed to retrieve directional Mean Square Slopes (MSSs). Results compared theoretically‐derived MSSs and in situ measurements co‐located buoys National Data Buoy Center (NDBC), showing good agreement most cases. Here, whole DDM, a more complete source information, exploited for first time GNSS‐R data. These...
This paper deals with the problem of constant false alarm rate detection extended objects in high-resolution synthetic aperture radar (SAR) images. Starting from receiver proposed by Guida and Longo, where some relevant properties location-scale distributions are exploited for ensuring against Weibull background, authors consider application algorithm to case spotlight SAR images collected an airborne sensor developed Defense Evaluation Research Agency laboratories. The has been reconceived...
We present the implementation of a facet-based simulator to investigate forward scattering L-band signals from realistic sea surfaces and its application spaceborne ocean Global Navigation Satellite System (GNSS) Reflectometry. This approach provides new flexible tool assess influence surface roughness on scattered GNSS signals. The motivation stems study by Clarizia <etal xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"/> , which revealed significant...
When GNSS signals reflect off of the surfaces lakes, rivers, wetlands, and other inland water bodies, are often sufficiently smooth to produce coherent reflections. The observable produced from reflections made by Reflectometry (GNSS-R) instruments exhibits particular features with respect diffusely scattered rough land wind-driven oceans allowing detection such bodies. Several different GNSS-R coherence approaches have been reported in literature developed among community over last several...
Objective: Chemotherapy of stage IIIA non-small cell lung cancer (NSCLC) using second generation, cisplatin-based combinations has shown to improve the results; however, distant relapses remain major problem. Encouraging results in treatment IV NSCLC with newer agents (gemcitabine, placlitaxel) encouraged us use them III. The aim this study was assess feasibility and efficacy induction chemotherapy cisplatin gemcitabine followed by surgery for patients (N2) NSCLC. Methods: From February 1996...
To report our experience with repeated pulmonary resection in patients local recurrent and second primary bronchogenic carcinoma, to assess operative mortality late outcome.The medical records of all who underwent a lung for carcinoma from 1978 through 1998 were reviewed.There 27 patients. They constituted 2.5% 1059 had undergone the same period. Twelve (1.1%) (group 1) recurrence that developed at median interval 24 months (range 4-83). The first was lobectomy ten segmentectomy two....
The paper intends to give a contribution toward the definition of fully decentralized voltage quality monitoring architecture by proposing employment self organizing sensor networks. According this paradigm each node can assess both performances monitored site, computed acquiring local information, and global grid section, exchanges information with its neighbors nodes. Thanks feature could automatically detect anomalies. Moreover system operator index for section inquiring any corresponding...
A stochastic model for delay-Doppler map (DDM) simulation from global navigation satellite system reflectometry (GNSS-R) systems is presented. The aim to provide a useful tool investigating the performance of estimation and retrieval algorithms that are based on finite time series. scattering inside cell modeled as sum random number contributions inner specular points that, mean such gets larger, tends compound-Gaussian process. statistical averages reveal fully consistent with previous...

The aim of this study is a retrospective evaluation survival in patients who had undergone lung resection for non-small cell cancer and whose microscopic residual disease at the bronchial margin was found, according to type infiltration, histology, lymph node involvement postoperative treatment.A total 1384 underwent Thoracic Surgery Unit University Siena from 1983 through 1998. All complete mediastinal lymphadenectomy guaranteed an accurate stadiation. Staging done TNM UICC classifications....
In this paper, we deal with the analysis of temporal coherence properties signal backscattered from sea surface, in hypothesis that it can be modeled as a compound-Gaussian process. Precisely, address problem measuring to what extent process, namely product nonnegative, slowly-varying modulating times rapidly varying Gaussian component, approximated by process random variance. The is restated terms binary test, wherein null constant sequence contrasted any alternative. test calibrated...
In this paper we address the problem of measuring coherence length sea-scattered signal. The technique propose requires data to be amenable a compound-Gaussian representation. core procedure consists in approaching as binary hypothesis test. order apply experimental preliminary calibration is necessary based on set training sequences with known characteristics. Finally, has been applied measure sea collected by scatterometer mounted "Forschungsplatform Nordsee" during SAXON experiment November, 1990.

Many sensors are suitable for accurate delineation of open water extent, but in vegetated environments, the vegetation canopy can obscure presence standing from detection. Detecting inundation extent these environments is especially critical identifying flooding where surface may exceed flood boundaries and extend into forests surrounding nearby lakes streams. Regular timely observations surfaces by optical be impeded both cloud cover vegetation. Here, two microwave techniques will...
The paper deals with the detection of signals unknown parameters in impulsive noise, modeled as a spherically symmetric random process. proposed model subsumes several interesting families noise amplitude distributions: generalized Cauchy, Laplace, Gaussian, contaminated normal. It also allows handling case correlated by whitening approach. maximum likelihood decision strategy is adopted, resulting canonical detector, which independent distribution noise. A general method for performance...
