Robotic Versus Laparoscopic Staging for Early Ovarian Cancer: A Case-Matched Control Study.
2017
Abstract Study Objective To evaluate the feasibility, surgical outcome, and oncologic results observed after robotic staging compared with conventional laparoscopic staging for patients with early-stage ovarian cancer patients. Design A retrospective cohort study (Canadian Task Force classification II-2). Setting Catholic University of the Sacred Heart, Rome, Italy. Patients Ninety-six patients underwent minimally invasive staging for presumed stage I ovarian cancer; 32 underwent the robotic approach (cases), and 64 underwent the laparoscopic approach (controls). Measurements and Main Results There was no statistically significant difference between the 2 approaches with regard to final Fed…
Software/Hardware Issues in Modelling Insect Brain Architecture
2011
The concept of cognitive abilities is commonly associated to humans and animals like mammals, birds and others. Nevertheless, in the last years several research groups have intensified the studies on insects that posses a much simpler brain structure even if they are able to show interesting memory and learning capabilities. In this paper a survey on some key results obtained in a joint research activity among Engineers and Neurogeneticians is reported. They were focussed toward the design and implementation of a model of the insect brain inspired by the Drosophila melanogaster. Particular attention was paid to the main neural centers the Mushroom Bodies and the Central Complex. Moreover a …
Robotizing meaningful work
2021
PurposeRobots have a history of replacing human labor in undesirable, dirty, dull and dangerous tasks. With robots now emerging in academic and human-centered work, this paper aims to investigate psychological implications of robotizing desirable and socially rewarding work.Design/methodology/approachTesting the holistic stress model, this study examines educational professionals’ stress responses as mediators between robotization expectations and future optimism in life. The study uses survey data on 2,434 education professionals.FindingsRespondents entertaining robotization expectations perceived their work to be less meaningful and reported more burnout symptoms than those with no roboti…
A Velocity Estimation Technique for a Monocular Camera Using mmWave FMCW Radars
2021
Perception in terms of object detection, classification, and dynamic estimation (position and velocity) are fundamental functionalities that autonomous agents (unmanned ground vehicles, unmanned aerial vehicles, or robots) have to navigate safely and autonomously. To date, various sensors have been used individually or in combination to achieve this goal. In this paper, we present a novel method for leveraging millimeter wave radar’s (mmW radar’s) ability to accurately measure position and velocity in order to improve and optimize velocity estimation using a monocular camera (using optical flow) and machine learning techniques. The proposed method eliminates ambiguity in optical flow veloci…
Test Methods for the Evaluation of Manufacturing Mobile Manipulator Safety
2016
International audience; This paper presents a test methodology for evaluating the safety of mobile manipulators (robot arms mounted on mobile bases). This methodology addresses the safety concerns relevant to modern, agile, manufacturing practices in which mobile manipulators will play a significant role. We consider 1) the unique capabilities and anticipated uses of mobile manipulators and 2) the potential exemptions and special cases in which their behavior may be unpredictable or otherwise contrary to the safety requirements. Finally, we define metrics for assessing compliance with functional safety requirements and anticipated performance.
Ritz Solution for Transient Analysis of Variable-Stiffness Shell Structures
2020
The dynamic response of thin-walled structures is driven by mass and stiffness distribution. As such, variable-stiffness (VS) composites offer opportunities to tune structural dynamic responses. To this extent, efficient analysis tools become increasingly important for structural analysis and design purposes. In this work, an efficient and versatile Ritz method for free vibrations and linear transient analysis of VS doubly curved shell structures is presented. VS shell structures are modeled as an assembly of shell-like domains. The shell kinematics is based on the first-order shear deformation theory, and no further assumption is made on the shallowness or on the thinness of the structure.…

Tecnologie Robotiche e responsabilità extracontrattuale: un'analisi comparata
2022
Attraverso un esame delle soluzioni giuridiche derivanti, da un lato, dal percorso normativo posto in essere dall’Unione Europea e, dall’altro lato, da quanto emerge dal case law in via di formazione nel mondo, con questo lavoro si vuole dimostrare che l’avvento delle tecnologie robotiche non comporta necessariamente l'individuazione di nuove categorie giuridiche né induce mutamenti radicali nel sistema consolidato dei principi della responsabilità civile. In questa prospettiva si vuole verificare se il ricorso alla categoria della responsabilità oggettiva possa consentire un livello di tutela adeguato del danneggiato senza per ciò stesso limitare o incidere negativamente sulla opera di inn…
Programación de microrrobots por bloques
2016
Material docente perteneciente a los cursos y talleres de difusión llevados a cabo en la ETSE-UV dentro de los programas del Servei d'Informació i Dinamització (SeDi) de la Universitat de València (Aprén Emprén, Ciència ARA, Talleres de Secundaria, Conèixer y NauJove). En los entornos tecnológicos educativos, se viene adoptando la práctica del uso de robots como incentivo a la programación y diseño de sistemas/automatismos. Debido al atractivo que éstos suscitan en los estudiantes, se genera un clima propicio para el aprendizaje. La programación y el montaje de robots no sólo tienen su aplicación en sí mismos, sino que permiten dar una idea global del funcionamiento de sistemas que se desar…
Optical flow estimation from multichannel spherical image decomposition
2011
International audience; The problem of optical flow estimation is largely discussed in computer vision domain for perspective images. It was also proven that, in terms of optical flow analysis from these images, we have difficulty distinguishing between some motion fields obtained with little camera motion. The omnidirectional cameras provided images with large filed of view. These images contain global information about motion and allow to remove the ambiguity present in perspective case. Nevertheless, these images contain significant radial distortions that is necessary to take into account when treating these images to estimate the motion. In this paper, we shall describe new way to comp…
