Real-Time Detection of Incipient Inter-Turn Short Circuit and Sensor Faults in Permanent Magnet Synchronous Motor Drives Based on Generalized Likelih…
2022
This paper presents a robust model-based technique to detect multiple faults in permanent magnet synchronous motors (PMSMs), namely inter-turn short circuit (ITSC) and encoder faults. The proposed model is based on a structural analysis, which uses the dynamic mathematical model of a PMSM in an abc frame to evaluate the system’s structural model in matrix form. The just-determined and over-determined parts of the system are separated by a Dulmage–Mendelsohn decomposition tool. Subsequently, the analytical redundant relations obtained using the over-determined part of the system are used to form smaller redundant testable sub-models based on the number of defined fault terms. Furthermore, fo…

Monitoring and Diagnosis of Failures in Squirrel-Cage Induction Motors Due to Cracked or Broken Bars
2011
In this paper three diagnostic procedures, based on on the vibration, current and instantaneous power monitoring for the detection and monitoring of incipient faults as cracks or bar breaks on squirrel cage motors are briefly reminded. The experimental investigations, carried out at the SDESLab (Sustainable Development Energy Savings Laboratory) of the University of Palermo in order to underline merits and drawbacks of the methods applied to the same die cast squirrel cage induction motor, are presented. The results of the investigations confirmed the effectiveness of the diagnostic procedures here considered.

Fatal cerebellar haemorrhage due to phenprocoumon poisoning.
1996
A 32-year-old patient died of a cerebellar haemorrhage and the blood coagulation analysis before death suggested defective synthesis of vitamin K-dependent clotting factors due to vitamin K deficiency. The post-mortem toxicological examination of different tissues revealed phenprocoumon poisoning as the cause of death. The differential diagnosis of vitamin K deficiency and the toxicology of hydroxycoumarins are discussed.
La inhibición, el autocontrol emocional, la memoria de trabajo y la supervisión ¿predicen las manifestaciones típicas de adultos con TDAH?
2019
Introducción. Los déficits en inhibición, control emocional, memoria de trabajo y supervisión se han evidenciado en numerosas investigaciones focalizadas en el trastorno por déficit de atención con hiperactividad (TDAH), pero la información sobre su posible influencia diferencial en las manifestaciones características del trastorno es escasa. Objetivos. El presente estudio se propuso analizar las relaciones de las funciones ejecutivas de regulación (inhibición y control emocional) y metacognitivas (memoria de trabajo y supervisión) con manifestaciones del TDAH y determinar el poder de predicción de esas cuatro funciones ejecutivas en dichas manifestaciones. Método. Sesenta y un jóvenes adul…
Innovative tools to diagnose the impact of land use practices on soil microbial communities
2018
International audience; Preservation and sustainable use of soil biological communities represent major challenges in the current agroecological context. Indeed, most of soil ecosystem services results from biological functions particularly driven by taxonomic and functional assemblages of microbiological communities (i.e. nutrient cycling, soil aggregation, depollution, etc.). Consequently, soil microbial communities are logical candidates as effective indicators of soil quality and sustainability. But, good biological indicators must be associated with references that encompass an operating range of measured values that allow performing the desired diagnosis. Even if numerous studies have…
Neurophysiologic Testing in Infants With Usher Syndrome Type 1
2009
Purpose: Usher syndrome type 1 needs to be diagnosed at early age, when speech therapy and cochlear implantation can stimulate communication in a deaf child who will confront an additional visual handicap. Molecular diagnosis is not routinely available. Visual function tests are not easily performed in young children. Before the age of six years, progressive retinal degeneration does not always show fundoscopic changes and few data are available regarding neurophysiologic abnormalities. This study was designed to describe electroretinogram (ERG) and visual evoked potentials (VEP) in a series of fourteen children with Usher syndrome type I.Methods: Monocular ERG and binocular VEP were perfor…
Perinatal management of gastroschisis
2014
Gastroschisis is an abdominal wall defect, typically located to the right of the umbilical cord, requiring an early surgical treatment shortly after birth. Affected patients can be identified during intrauterine life with US and should be delivered in referral hospitals where a multisciplinary approach can be provided, involving neonatologists, clinical geneticists, surgeons and other specialists. These patients require a complex management in Neonatal Intensive Care Unit (NICU) and a long term follow-up after discharge. Exceed the acute neonatal condition, gastroschisis has a good prognosis, if there are no overlapping complications, and it should be differentiated from omphalocele, burden…
Parental and professional agency in terminations for fetal anomalies: analysis of Finnish women's accounts
2013
This study explores the construction of parental and professional agency in the written accounts by women who have undergone selective abortion (N=8). The analysis of the data was based on qualitative, linguistic discourse analysis. The accounts indicate that the mothers themselves exhibited both strong and weak agency during the process of prenatal diagnosis. The role of the professionals was usually discussed in these accounts concerning only the phases of pregnancy when something out of ordinary had been detected. After the termination, the mothers expressed that they were forced to exhibit strong agency and find ways to cope with their distress unaided due to a lack of professional supp…
