A review of diagnostics and prognostics of low-speed machinery towards wind turbine farm-level health management
2016
Abstract Large wind farms are gaining prominence due to increasing dependence on renewable energy. In order to operate these wind farms reliably and efficiently, advanced maintenance strategies such as condition based maintenance are necessary. However, wind turbines pose unique challenges in terms of irregular load patterns, intermittent operation and harsh weather conditions, which have deterring effects on life of rotating machinery. This paper reviews the state-of-the-art in the area of diagnostics and prognostics pertaining to two critical failure prone components of wind turbines, namely, low-speed bearings and planetary gearboxes. The survey evaluates those methods that are applicabl…
Reliable diagnostics using wireless sensor networks
2019
International audience; Monitoring activities in industry may require the use of wireless sensor networks, for instance due to difficult access or hostile environment. But it is well known that this type of networks has various limitations like the amount of disposable energy. Indeed, once a sensor node exhausts its resources, it will be dropped from the network, stopping so to forward information about maybe relevant features towards the sink. This will result in broken links and data loss which impacts the diagnostic accuracy at the sink level. It is therefore important to keep the network's monitoring service as long as possible by preserving the energy held by the nodes. As packet trans…
A concept to empower self-management of psychophysiological wellbeing: preliminary user study experiences.
2009
In prevention of chronic diseases, health promotion and early interventions based on self-management should be emphasized. Mental health problems and stress cause a significant portion of healthcare costs, and also complicate the management of other chronic conditions. In addition to physical health, psychophysiological and social wellbeing should be equally promoted. Thus, we have previously designed and reported the P4Well or Pervasive Personal and PsychoPhysiological management of WELLness concept for working-age citizens. The concept supports the stress and recovery management on a daily basis through improved health management strategies, and combines psychological methods with persona…
Rotor-bar breakage mechanism and prognosis in an induction motor
2015
© 1982-2012 IEEE. This paper proposes a condition-based maintenance and prognostics and health management (CBM/PHM) procedure for a rotor bar in an induction motor. The methodology is based on the results of a fatigue test intended to reproduce in the most natural way a bar breakage in order to carry out a comparison between transient and stationary diagnosis methods for incipient fault detection. Newly developed techniques in stator-current transient analysis have allowed tracking the developing fault during the last part of the test, identifying the failure mechanism, and establishing a physical model of the process. This nonlinear failure model is integrated in a particle filtering algor…
La gobernanza compartida y la razonabilidad como aportaciones éticas a la política sanitaria
2013
La salud es uno de los derechos humanos fundamentales. Reconocerla como tal conlleva la obligación estatal de garantizar un mínimo de oportunidades para mantenerla o recuperarla cuando se pierde. Ese mínimo puede quedar sin cubrir en épocas de crisis económica, como la que estamos viviendo. La medicina gestionada (managed care) centrada en lo económico surgió tras la crisis de 1973, con el objetivo de condicionar las decisiones clínicas por factores económicos. En la práctica, la medicina gestionada convirtió el control de los costes económicos en un fin en sí mismo olvidando la equidad, por lo que ha sido cuestionada éticamente. Desde entonces, muchos autores han afrontado la tarea de comp…
A cost and performance comparison of Public Private Partnership and public hospitals in Spain
2016
Public-private partnership (PPP) initiatives are extending around the world, especially in Europe, as an innovation to traditional public health systems, with the intention of making them more efficient. There is a varied range of PPP models with different degrees of responsibility from simple public sector contracts with the private, up to the complete privatisation of the service. As such, we may say the involvement of the private sector embraces the development, financing and provision of public infrastructures and delivery services. In this paper, one of the oldest PPP initiatives developed in Spain and transferred to other European and Latin American countries is evaluated for first ti…
Applying Benford’s Law to Monitor Death Registration Data: A Management Tool for the COVID-19 Pandemic
2021
In Spain, the COVID-19 pandemic has impacted the various regions of the country differ7 ently. The availability of reliable and up-to-date information has proved to be fundamental for the 8 management of this health crisis. However, especially during the first wave of the pandemic (Feb9 ruary-August 2020), the disparity in the recording criteria and in the timing of providing these fig10 ures to the central government created controversy and confusion regarding the real dimension of 11 the pandemic. It is therefore necessary to have objective and homogeneous criteria at the national 12 level to guide health managers in the correct recording and evaluation of the magnitude of the pan13 demic…
The future of health communication : innovating through partnerships
2015
The Preamble of the Constitution of the World Health Organization reminds us that «Informed opinion and active cooperation on the part of the public are of the utmost importance in the improvement of the health of the people» (Grad, 2002). Nonetheless, nearly seven decades later, the conditions under which people can be informed and actively participate in their health management in a meaningful way are being globally challenged. Drawing from experience in a variety of areas that I will delve into in this article, I remain a believer that we can marshal the necessary forces to advance the communication of health issues and create a base for a health-literate population to make smart(er), he…
Focus on Liability of Residences for Elderly and Sick People: A Case Series and Medico-Legal Issues
2023
Residences for elderly and sick people, self-sufficient or dependent, are varied. To date, the liability profiles of these structures are not clearly delineated, and increasingly often, their operating and organization criteria are entrusted to subnational, regional, or local regulations. Among the various deficits, there is the keeping of a complete and detailed documentation/diary of the patient, the lack of which can generate medico-legal problems. In this paper, we present three cases of guests in residences for a dependent person brought to the attention of the Institute of Forensic Medicine of the University Hospital of Palermo due to criminal proceedings, where the lack of existing d…
Severe Psychological Distress of Evacuees in Evacuation Zone Caused by the Fukushima Daiichi Nuclear Power Plant Accident: The Fukushima Health Manag…
2015
Background Following the Great East Japan Earthquake on March 11, 2011, the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant has continued to affect the mental health status of residents in the evacuation zone. To examine the mental health status of evacuee after the nuclear accident, we conducted the Mental Health and Lifestyle Survey as part of the ongoing Fukushima Health Management Survey. Methods We measured mental health status using the Kessler 6-item psychological distress scale (K6) in a total of 73,569 (response rate: 40.7%) evacuees aged 15 and over who lived in the evacuation zone in Fukushima Prefecture. We then dichotomized responders using a 12/13 cutoff on the K…
