Using of a uncertainty model of an polyarticulated coordinates measuring arm to validate the measurement in a manufacturing processsus
2014
International audience; Coordinates Measuring Arms (CMA) are increasingly used to control industrial parts and are often an alternative to CMM controls that require conditions of laboratory measurement and involve significant costs. However, the control of uncertainties is often not guaranteed because the measurement process is complex and there is no standard for setting a framework qualification process of the measurement process.The proposed study, in this paper, is a first approach to model the measurement uncertainties of a CMA with contact sensor. The problem is complex because there are many sources of uncertainty, largely due to variability in the handling carried out by the operato…
Käytettävyyssuunnittelun asiantuntija- ja testausmenetelmien sisällyttäminen ketterään ohjelmistokehitykseen
2012
Tutkielmassa käsitellään käytettävyyssuunnittelun asiantuntija- ja testausmene-telmien sisällyttämistä ketterään ohjelmistokehitykseen. Aihetta on toistaiseksi tutkittu varsin vähän, mutta se on todettu tärkeäksi kehityssuunnaksi IT-alalla. Käytettävyyssuunnittelun ja ketterän ohjelmistokehityksen yhteneväiset tavoit-teet on todettu yhdeksi argumentiksi integroida menetelmät keskenään. Tutkielma käsittelee käytettävyyssuunnittelun yleisimmät asiantuntija- ja tes-tausmenetelmät, ketterän ohjelmistokehityksen filosofian sekä kaksi käytetyintä menetelmää, jotka ovat Scrum ja eXtreme Programming. Näiden ilmiöiden poh-jalta lähestytään käytettävyyssuunnittelun testaus- ja arviointimenetelmien si…
HERMIA: An Heterogeneous and Reconfigurable Machine for Image Analysis
1990
In this paper is described the general architecture of an Heterogeneous and Reconfigurable Machine for Image Analysis (HERMIA); the first prototype of the system has been developed at the University of Palermo. Conventional hardware has been used in order to emulate the machine and evaluate the system performance Preliminary results are presented and discussed.
Biased Modern Heuristics for the OCST Problem
2011
Biasing modern heuristics is an appropriate possibility in designing problem-specific and high-quality modern heuristics. If we have knowledge about a problem we can bias the design elements of modern heuristics, namely the representation and search operator, fitness function, the initial solution, or even the search strategy. This chapter presents a case study on how the performance of modern heuristics can be increased by biasing the design elements towards high-quality solutions. Results show that problem-specific and biased modern heuristics outperform standard variants and even for large problem instances high-quality solutions can be found.
Manipulating feedback on schizophrenia: Evidence from a Posner task.
2021
Abstract Individuals with schizophrenia show difficulties in achieving vital objectives. Abnormal behavioral and emotional responses to environmental feedback may be some of the psychological mechanisms underlying this lack of goal attainment in schizophrenia. The present study aims to assess how different types of feedback may affect performance in a computerized affective Posner task (non-monetary vs. monetary rewards; contingent vs. non-contingent feedback). The sample was composed of 32 patients with schizophrenia and 35 controls. Reaction times and error rates were the behavioral measurements. The emotional experience was assessed through self-reported affective scales. The results ind…
Turma Alfa: a dilemática fronteira entre práticas educativas inclusivas e práticas educativas exclusivas
2018
Abstract: This paper stems from an ongoing investigation on the theme "Educating places: practices, voices and pathways of inclusive education”. This project seeks to answer, among others, the following questions: i) which processes and factors, subjects, action rationales and (institutional, local, community) partnerships contribute to building local inclusive education practices, in the views of actors involved?; ii) which (social, institutional, biographical) processes and factors stop the negative spiral of school underachievement, school dropout and early school leaving and favour the youngsters’ remobilization to learn and build successful academic pathways?The study design consists o…
Population dynamics based on ladder bosonic operators
2021
Abstract We adopt an operatorial method, based on truncated bosons, to describe the dynamics of populations in a closed region with a non trivial topology. The main operator that includes the various mechanisms and interactions between the populations is the Hamiltonian, constructed with the density and transport operators. The whole evolution is derived from the Schrodinger equation, and the densities of the populations are retrieved from the normalized expected values of the density operators. We show that this approach is suitable for applications in very large domain, solving the computational issues that typically occur when using an Hamiltonian based on fermionic ladder operators.
Using an Object-Oriented Approach for Scalable Flexibility in Manufacturing
2012
In this paper, it is briefly explained how to configure the different resource modules that actually control the tasks of the physical device and put together a work cell consisting of other FMS resources. Finally, an example on building a workcell using a hierarchical approach is presented.
A microcomputer system for controlling classical conditioning experiments
1994
A microcomputer-based laboratory system for controlling stimulus presentations and data acquisition in classical conditioning experiments is described. The system comprises an Intel 386/486-based microcomputer and a commercially obtained low-cost counter/timer board with input/output lines for stimulus timing and external device control. A simple, yet versatile custom-designed structured programming language is provided for performing an unlimited number of stimulus configurations and their sequences. In electrophysiological studies, the system can be flexibly connected to computer-controlled signal conditioning systems for the amplification and filtering of multiunit and evoked field poten…
A Teledentistry system for the second opinion
2014
In this paper we present a Teledentistry system aimed to the Second Opinion task. It make use of a particular camera called intra-oral camera, also called dental camera, in order to perform the photo shooting and real-time video of the inner part of the mouth. The pictures acquired by the Operator with such a device are sent to the Oral Medicine Expert (OME) by means of a current File Transfer Protocol (FTP) service and the real-time video is channeled into a video streaming thanks to the VideoLan client/server (VLC) application. It is composed by a HTML5 web-pages generated by PHP and allows to perform the Second Opinion both when Operator and OME are logged and when one of them is offline.
