Oral history interview with Illinois State University Professor J. Randy Winter. The interview was conducted on June 19, 2007, by Elaine Graybill, as part of the Illinois State University Oral History Project. Dr. Winter was professor of agricultural economics, who joined the Illinois State University faculty in 1981. He was agriculture department chairperson from 1993 to 2004 and was instrumental in the 2001 relocation of the university farm from Gregory Street to Lexington, Illinois.https://ir.library.illinoisstate.edu/soh/1015/thumbnail.jp

Estimation of the state of health (SOH) of batteries using discrete curvature feature extraction

Lithium battery applications in a variety of engineering sectors must be safe and reliable while maintaining a high level of energy efficiency. An accurate assessment of the battery's state of health (SOH) is critical in battery management systems (BMS). In recent years, it has been proved that machine learning is effective at estimating SOH. This work proposes a novel approach of health indicator (HI) extraction based on the U-chord curvature model, based on a complete analysis of battery aging data. In contrast to previous approaches for feature extraction, our method splits the discharge process into various phases based on the curvature of the discharge curve and extracts many HIs with a high correlation to battery SOH in the discharge platform stage of the discharge curve. To demonstrate the superiority of the proposed model, several well-known machine learning algorithms are employed to estimate SOH using extracted attributes. Long short-term memory (LSTM) and artificial neural networks (ANNs) are examples of these techniques. Accuracy, reliability, and robustness of the proposed model are evaluated using three publicly available data sets. According to the data, the model appears to be capable of accurately calculating the battery's SOH, with a mean absolute error of less than 1.08% and a root mean square error of less than 1.46% for various battery types

Tasa de diagnóstico de pólipos en función de la indicación de la colonoscopia

El diagnóstico del CCR se establece con colonoscopia. Habitualmente esta se indica por la presencia de síntomas como es la rectorragia. El diagnóstico precoz del CCR se puede realizar a partir de la indicación de la colonoscopia, bien por la detección de sangre oculta en heces (SOH) o bien por la existencia de antecedentes familiares (AF). El pólipo de colon adenomatoso se considera una lesión pre-maligna y su resección es básica en la prevención del CCR. Nos proponemos comparar los hallazgos endoscópicos, concretamente la presencia de pólipos y de CCR, de los pacientes a los que se solicita la colonoscopia por rectorragia frente a los pacientes a los que se les solicita por AF o SOH. Se seleccionaron de forma consecutiva 100 pacientes a partir de una base de datos anonimizada del servicio de digestivo del Hospital Clínico Universitario de Valladolid. Cuarenta de ellos con rectorragia y 60 asintomáticos, divididos en 30 pacientes con AF y otros 30 pacientes con SOH. Se recogieron de forma retrospectiva, y a partir de los informes de las colonoscopias, se analizó la presencia, número, tamaño y tipo de los pólipos de colon, así como la presencia de CCR. El valor de p<0,05 fue considerado estadísticamente significativo. -Resultados: Al comparar los hallazgos de la colonoscopia en pacientes asintomáticos frente a pacientes con rectorragia no se han encontrado diferencias estadísticamente significativa en cuanto a la presencia de pólipos (48% vs 40%), pólipos mayores de 1 cm (20% vs 7,5%), o CCR (6% vs 10%). En la comparación de pacientes estudiados con colonoscopia por AF frente a los pacientes estudiados por SOH, la presencia de pólipos (33,3% vs 63,3%) y la presencia de pólipos > 1cm (6,7% vs 33,3%) fueron mayores en pacientes con SOH de forma estadísticamente significativa. Con respecto a la presencia de CCR, fue superior en los pacientes con SOH (0% vs 13,3%) con una diferencia que se aproximó mucho a la significación estadística (p 0,06). La frecuencia de pólipos o CCR no es mayor entre pacientes con rectorragia que en pacientes asintomáticos. El test de SOH positivo supone mayor tasa de diagnóstico de pólipos de colon, de pólipos mayores de 1 cm y de CCR que en caso de colonoscopia indicada por AF.Grado en Medicin

Capacity State-of-Health Estimation of Electric Vehicle Batteries Using Machine Learning and Impedance Measurements

With the increasing adoption of electric vehicles (EVs) by the general public, a lot of research is being conducted in Li-ion battery-related topics, where state-of-health (SoH) estimation has a prominent role. Accurate knowledge of this parameter is essential for efficient and safe EV operation. In this work, machine-learning techniques are applied to estimate this parameter in EV applications and in diverse scenarios. After thoroughly analysing cell ageing in different storage conditions, a novel approach based on impedance data is developed for SoH estimation. A fully-connected feed-forward neural network (FC-FNN) is employed to estimate the battery&rsquo;s maximum available capacity from a small set of impedance measurements. The method was tested for estimation in long-term scenarios and for diverse degradation procedures with data from real EV batteries. High accuracy was obtained in all situations, with a mean absolute error as low as 0.9%. Thus, the proposed algorithm constitutes a powerful and viable solution for fast and accurate SoH estimation in real-world battery management systems

The role of powered instrumentation in the removal of antrochoanal polyps: a 10-Year Review

Antrochoanal polyps are rare lesions. We report a series of 40 consecutive cases of antrochoanal polyps treated in our tertiary centre over a period of ten years between May 1998 and April 2008. The median age of the patients was 37 years. The most common clinical symptom was nasal obstruction (92.5%) followed by rhinorrhoea (45%), postnasal drip (35%) and snoring (22.5 %). The median period of follow-up of these patients was 30 months. Various surgical approaches were used; the commonest was powered endoscopic polypectomy and middle meatal antrostomy in 28 patients (70%), followed by endoscopic polypectomy and middle meatal antrostomy in seven patients (17.5%). Five patients (12.5%) underwent powered endoscopic polypectomy without middle meatal antrostomy. In addition, two patients had septoplasty and one had a frontal sinustomy. There were six patients (15%) who had combined sublabial antrostomy. No major complications occurred; four patients relapsed; three patients had initial operation performed elsewhere and one patient developed recurrence after the first surgery. The median hospitalization period was three days. We conclude that, the use of powered instrumentation in the removal of antrochoanal polyps is safe, effective and associated with minimal morbidity
