Is Hysteroscopy Better than Ultrasonography for Uterine Cavity Evaluation? An Evidence-Based and Patient-Oriented Approach
2016
Evaluation of the uterine cavity is an important part of the gynecological check, especially in symptomatic women and, over the last few decades, a number of technical and technological advancements has allowed a superb investigation of this organ. Traditionally, transvaginal ultrasound (TVUS) has been the first-line diagnostic tool for evaluating uterine diseases, also considering that gynecologists are familiar with the technique since it is included in the basic training in obstetrics and gynecology. Nevertheless, to date “office hysteroscopy” received growing attention since the development of smaller-diameter hysteroscopes which has made it possible to easily perform the hysteroscopy …
Strategic Decisions in Task-Oriented Reading.
2015
AbstractAnswering questions from texts are assessment and instructional activities that are frequently used in schools. Nevertheless, little is known about the strategic processes that students take while performing these tasks. We explored the amount and frequency that students initially read of a text before they answered questions pertaining to the material. In a procedure similar to the one used in the PISA (Program for International Students Assessment), one-hundred-seventy students between 7thand 9thgrade read and answered several questions designed to assess task-oriented reading in three specific texts. We recorded on-line indexes that evaluated student behavior (e.g., the amount of…
High Performance FOC for Induction Motors with Low Cost ATSAM3X8E Microcontroller
2018
In this paper the Authors present the Arduino Due board application for an induction motor field oriented control (FOC) algorithm. The low cost Arduino Due board is equipped with a ATSAM3X8E microcontroller that performs the algorithm calculation, data processing, current signals and speed/position data acquisition. The control algorithm has been developed with the help of the open source Arduino integrated development environment, whereas a user friendly control interface, used to manage the speed or position set point, has been developed in Java language by means of an other open source software, namely, Processing. An experimental test bed has been set up in order to validate the FOC sys…
Separation of Concerns and Role Implementation in the PASSI Design Process
2007
The use of design patterns proved successful in lowering the development time and number of errors when producing software with the object-oriented paradigm. In previous works we engaged the production of a tool for the reuse of patterns for multi-agent systems. Now we are fronting a new problem: automatic code generation for agents, designed with a specific methodology, with the support of design patterns and using an aspect oriented approach. In this work we present our preliminary experiences in the identification, description, production and use of aspects for multi agent systems and a tool for code production.
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
Assessing the Comprehension of Questions in Task-Oriented-Reading // Evaluación de la comprensión de las preguntas en lectura-orientada-a-tareas
2012
El objetivo del estudio fue analizar una metodologia de evaluacion del modelo mental de tarea, en lectura-orientada-a-tareas. 66 estudiantes universitarios leyeron dos textos y contestaron preguntas. Para cada pregunta elaboramos un item sobre las demandas de la pregunta. Las alternativas de respuesta combinaban versiones correctas o erroneas de los componentes del modelo de pregunta; nucleo y proceso. Analizamos el formato de aplicacion, relacion con rendimiento, capacidad para discriminar entre niveles de comprension y funcionamiento psicometrico de los items. Cuando la evaluacion se aplico antes de responder, las puntuaciones mejoraron y se relacionaron con rendimiento. Esta aplicacion p…
Neural based MRAS sensorless techniques for high performance linear induction motor drives.
2010
This paper proposes a neural based MRAS (Model reference Adaptive System) speed observer suited for linear induction motors (LIM). Starting from the dynamical equation of the LIM in the synchronous reference frame in literature, the so-called voltage and current models of the LIM in the stationary reference frame, taking into consideration the end effects, have been deduced. Then, while the inductor equations have been used as reference model of the MRAS observer, the induced part equations have been discretized and rearranged so to be represented by a linear neural network (ADALINE). On this basis, the so called TLS EXIN neuron has been used to compute on-line, in recursive form, the machi…
Promotion of polygeneration for buildings applications through sector- and user-oriented “high efficiency CHP” eligibility criteria
2014
Abstract The eligibility criteria adopted to assess polygeneration plants as “highly efficient” can play a determinant role in favouring or discouraging the market growth of polygeneration systems, especially for buildings applications where economic viability is often more difficult to achieve. Based on the current European framework, in this paper the opportunity to adopt sector- and user-oriented criteria is discussed. After having identified three buildings with different uses (a large hotel, a hospital and an office building), the optimal lay-out and operation strategy of a polygeneration plant serving each building is determined; then, ex-post processing of economic and energetic resu…
MetaMeth: A tool for process definition and execution
2006
Nowadays, several different tools are used in Software Engineering; in this work we are mainly interested to those supporting the design phases. These are usually classified in three categories: CASE, CAME, CAPE tools. MetaMeth is a CAME and a CAPE tool at the same time
Cohesion of planning and programming the development of regions in the conditions of a territorially-oriented policy
2015
The aim of the article is to identify the degree of cohesion of goals and needs of functional areas development with targets defined in the development of communes and a region. The functional areas: urban and sub-regional of Opole Province make the case study here. The study was conducted on the basis of documents which deal with planning and programming of the development of regional, local, as well as functional areas. As a result of the study, it was established that: the degree of adjustment of the targets defined in the development of functional areas is higher with reference to goals of the regional rather than local development. This results from greater possibilities of financing t…
