In this paper, an original method for bearing fault detection in high speed synchronous machines is presented. This method is based on the statistical process of Welch's periodogram of the stator currents in order to obtain stable and normalized fault indicators. The principle of the method is to statistically compare the current spectrum to a healthy reference so as to quantify the changes ove...

Abstract: Much of America’s promise is predicated on economic mobility—the idea that people are not limited or defined by where they start, but can move up the economic ladder based on their efforts and accomplishments. Family income mobility—changes in individual families’ income positions over time—is one indicator of the degree to which the eventual economic wellbeing of any family is tether...

The study aimed to apply the National Economic Indicator on data from a cross-sectional population-based study (nw =2,197) in the city of Ribeirão Preto, Southeastern Brazil, in 2006. Compared to Brazil, the indicator presented a concentration around the last five deciles and was similar to that of the municipality of São Paulo, also in Southeastern Brazil. Differences were observed concerning ...

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

background: one of the main and basic pillars of health system promotion is the equitable distribution of health facilities in order to ensure fair access of people in the community to the health services. the goal of this study was to classify the health structural indicators in golestan province using scalogram analysis model. method: a descriptive study was conducted in 2010. data related to...

Recently, two new indicators (Equalized Mean-based Normalized Proportion Cited, EMNPC, the Mean-based Normalized Proportion Cited, MNPC) were proposed which are intended for sparse data. We propose a third indicator (Mantel-Haenszel quotient, MHq) belonging to the same indicator family. The MHq is based on the MH analysis – an established method for polling the data from multiple 2×2 contingenc...

AIM To examine constitutional alterations of CDKN2A/p16INK4A locus as a potential indicator of melanoma predisposition among the first-degree relatives of patients with malignant melanoma. METHOD The study included eight families with a single member affected with melanoma. Members of the families were screened for allelic cosegregation with 9p21 region polymorphic markers IFNA, D9S126, and D...

BACKGROUND Early identification of frailty is important for proactive primary care. Currently, however, there is no consensus on which measure to use. Therefore, we examined whether a Frailty Index (FI), based on ICPC-coded primary care data, and the Groningen Frailty Indicator (GFI) questionnaire identify the same older people as frail. METHODS We conducted a cross-sectional, observational s...

Errors in navigational instruments can significantly affect flight safety. Airspeed is a key piece of navigational data that depends on accurately measured air pressure, which in turn depends on accurately measured air temperature. Instead of measuring the outside air temperature in real time, cockpit instruments are preprogramed with standard air temperature values for different flight altitud...

The GERRI project materializes the Grenelle Environnement’s goals, of which the energy management of a territory is a facet. The aim is to forecast future energy production and consumption, bearing in mind economic and ecological indicators, and using a large number of interactions schemes between the involved parties. The originality of this paper is to present a new approach using the multi-a...
