Completeness and timeliness: Cancer registries could/should improve their performance.

2015

Abstract Cancer registries must provide complete and reliable incidence information with the shortest possible delay for use in studies such as comparability, clustering, cancer in the elderly and adequacy of cancer surveillance. Methods of varying complexity are available to registries for monitoring completeness and timeliness. We wished to know which methods are currently in use among cancer registries, and to compare the results of our findings to those of a survey carried out in 2006. Methods In the framework of the EUROCOURSE project, and to prepare cancer registries for participation in the ERA-net scheme, we launched a survey on the methods used to assess completeness, and also on t…

Improved resource allocation strategy in SU-CoMP network

2011

Coordinated multi-point transmission and reception (CoMP) for single user, named as SU-CoMP, is considered as an efficient approach to mitigate inter-cell interference in orthogonal frequency division multiple access (OFDMA) systems. Two prevalent approaches in SU-CoMP are coordinated scheduling (CS) and joint processing (JP). Although JP in SU-CoMP has been proved to achieve a great link performance improvement for the cell-edge user, efficient resource allocation (RA) on the system level is quite needed. However, so far limited work has been done considering JP, and most existing schemes achieved the improvement of cell-edge performance at cost of the cell-average performance degradation …

Deep multimodal fusion for semantic image segmentation: A survey

2021

International audience; Recent advances in deep learning have shown excellent performance in various scene understanding tasks. However, in some complex environments or under challenging conditions, it is necessary to employ multiple modalities that provide complementary information on the same scene. A variety of studies have demonstrated that deep multimodal fusion for semantic image segmentation achieves significant performance improvement. These fusion approaches take the benefits of multiple information sources and generate an optimal joint prediction automatically. This paper describes the essential background concepts of deep multimodal fusion and the relevant applications in compute…

Essential elements of professional nursing environments in Primary Care and their influence on the quality of care

2018

Objectives Nursing work environments (NWE) are key determinants of care quality. Our study aimed to evaluate the characteristics of nursing environments in primary care settings in the Canary Islands, and identify crucial components of such environments to improve quality. Method We conducted a cross-sectional study in primary care organisations using the Practice Environment Scale - Nursing Work Index (PES-NWI) tool. We collected sociodemographic variables, PES-NWI scores, and selected the essential items conducive to optimal care. Appropriate parametric and non-parametric statistical tests were used to analyse relations between variables (CI = 95%, error = 5%). Results 144 nurses particip…

A GIS-MCDM-based road network planning for tourism development and management in Arasbaran forest, Iran.

2019

It is very important for managers to plan a road network that meets all the requirements for tourism development and management. The aim of this study was to evaluate and modify an existing road network for tourism purposes in the Arasbaran protected area. First, the map layers of effective criteria were prepared in GIS and were standardized by a fuzzy logic approach and finally combined considering their relative importance weights obtained through pair-wise comparison technique. A suitability map was then acquired. After that, 14 different scenarios of road network were designed to access the recreational area using PEGGER extension in ArcView. Then, they were evaluated in terms of techni…

Analysis a DSP Implementation and Experimental Validation of a Loss Minimization Algorithm Applied to Permanent Magnet Synchronous Motor Drives

2004

In this paper a new loss minimization control algorithm for inverter-fed permanent-magnet synchronous motors (PMSM), which allows to reduce the power losses of the electric drive without penalty on its dynamic performances, is analyzed, experimentally realized and validated. In particular, after a brief recall of two loss minimization control strategies (the "search control" and the "loss-model control"), both a modified dynamic model of the PMSM, which takes into account the iron losses, and a "loss-model" control strategy, are treated. Experimental tests on a specific PMSM drive employing the proposed loss minimization algorithm were performed aiming to validate the actual implementation.…

Essential strategies in HAI prevention and control: performance assessment through the implementation of the HAI-CoSIP tool of the GISIO-SItI group. …

2018

Healthcare-Associated Infections are a great concern for worldwide healthcare systems and represent a considerable threat to patient safety, leading to adverse clinical outcomes. A defined panel of indicators represents a key element to guide Healthcare Organizations towards identification of main gaps, implementation of effective actions and continuous improvements on Healthcare-Associated Infections prevention and control activities. A review on accreditation systems conducted by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene Preventive Medicine and Public Health revealed a substantial heterogeneity of implemented standards and led to the development of a co…

Super resolved optical system for objects with finite sizes using circular gratings

2015

We present a real time all optical super resolution method for exceeding the diffraction limit of an imaging system which has a circular aperture. The resolution improvement is obtained using two fixed circular gratings which are placed in predetermined positions. The circular gratings generate synthetic circular duplications of the aperture, thus they are the proper choice for a circular aperture optical system. The method is applicable for both spatially coherent and incoherent illuminations, as well as for white light illumination. The resolution improvement is achieved by limiting the object field of view. The proposed method is presented analytically, demonstrated via numerical simulat…

La compra silenciosa. Arrendamientos, estabilidad y mejoras en la agricultura valenciana de regadío (1850–1930)

2007

Resumen Este articulo analiza como fue posible, en el regadio valenciano, un desarrollo agrario basado en el arrendamiento de pequenas explotaciones. Del estudio de los contratos firmados en la huerta de Gandia se deduce, en primer lugar, que los arrendatarios ocupaban la parcela durante un periodo bastante prolongado de tiempo, que tendio a crecer durante la segunda mitad del siglo XIX; y, en segundo, que a menudo los cultivadores eran indemnizados al finalizar su contrato por las mejoras que habian introducido. A largo plazo, todo ello consolido su posicion, porque el cultivador se convirtio en “semipropietario” de hecho de la tierra mejorada. Por su parte, los terratenientes rentistas ob…
