    The newest and most promising type of pneumatic actuators is the pneumatic artificial muscle (PAM). Different designs have been developed, but the McKibben muscle is the most popular and is made commercially available by different companies (e. g. Fluidic Muscle manufactured by Festo Company and Shadow Air Muscle manufactured by Shadow Robot Company). Pneumatic artificial muscles have a wide range of use in industrial and medical fields. There are a lot of advantages of these muscles like the high strength, good power-weight ratio, low price, little maintenance needed, great compliance, compactness, inherent safety and usage in rough environments. The main disadvantage is that their dynamic behaviour is highly nonlinear. The most often mentioned characteristic of PAMs is the force as a function of pressure and contraction. In this paper the newest function approximations for the force generated by Fluidic Muscles are investigated in MS Excel

    In the international publications, in the last decades, incidence and mortality of lung cancer was the highest in Hungary in the ranking of European countries and even worldwide, despite the fact that no lung cancer incidence data were reported from Hungary until 2019. In the studies published by our working group at the end of 2019 and in the first half of 2020, we were the first to publish Hungarian lung cancer incidence and mortality data based on research on the NEAK database. The results of this study showed a significant, 25-30% lower incidence of lung cancer in Hungary than the previously reported data. Based on these findings, it was determined that the previously reported Hungarian lung cancer incidence and mortality data can be compiled due to different methodological applications of inadequately calculated results, and Hungarian lung cancer incidence and mortality are equally high, but not higher than the average in Central European countries. In addition, a decrease in the incidence and mortality of male lung cancer was measured between 2011 and 2016, while increasing values were found for women

    A gépi beszédfelismerés egyik dönt fontosságú eleme a beszéd akusztikai lényegének kiemelése, különösen a zajos környezetben történ alkalmazásoknál, amely jelen esetben közlekedési zajjal terhelt akusztikai környezetet jelentett. Emiatt helyeztük vizsgálatunk középpontjába a zajtr és hagyományos beszédfelismerési lényegkiemelési eljárásokat. A tanítást és tesztelést hat nyelven végeztük el: angol, francia, magyar, német, olasz, spanyol. Teszteléshez a telefonos hálózaton keresztül az utcáról vagy jármbl rögzített adatbázist használtunk. Alaprendszerként teszteltük a HTK és a SPHINX eszközkészletben, vagy általunk is implementált Mel Frequency Cepstral Coefficients (MFCC) és Perceptual Linear Prediction (PLP) módszereket. Az újabb módszerek között a Power-Normalized Cepstral Coefficients (PNCC) és a Perceptual Minimum Variance Distortionless Response (PMVDR) szerepel

    Conditions of Change: The Regional Role of a Romanian Agricultural Secondary School

    Get PDF
    The focus of our study is a high school with an agricultural education programme operating in a rural micro-region within Harghita County (Romania), in which context the relationship between the school and the regional society comes under analysis. Since the 1970s, it has been the school’s mission to provide the micro-region with professionals with secondary education, and today it still intends to maintain this micro-regional function. It has been struggling with significant operational and maintenance problems for several years now, while the evolution of its micro-regional role is uncertain. The present study takes under scrutiny the attitude of the parents and the region’s élites towards the school and its regional role as well as analyses the school’s service marketing practices towards the region. Analysis results indicate that repositioning the regional role of the school seems to offer a way out and a development opportunity for the institution

    Revising Incidence and Mortality of Lung Cancer in Central Europe: An Epidemiology Review From Hungary

    Objective: While Hungary is often reported to have the highest incidence and mortality rates of lung cancer, until 2018 no nationwide epidemiology study was conducted to confirm these trends. The objective of this study was to estimate the occurrence of lung cancer in Hungary based on a retrospective review of the National Health Insurance Fund (NHIF) database. Methods: Our retrospective, longitudinal study included patients aged ≥20 years who were diagnosed with lung cancer (ICD-10 C34) between 1 Jan 2011 and 31 Dec 2016. Age-standardized incidence and mortality rates were calculated using both the 1976 and 2013 European Standard Populations (ESP). Results: Between 2011 and 2016, 6,996 - 7,158 new lung cancer cases were recorded in the NHIF database annually, and 6,045 - 6,465 all-cause deaths occurred per year. Age-adjusted incidence rates were 115.7-101.6/100,000 person-years among men (ESP 1976: 84.7-72.6), showing a mean annual change of - 2.26% (p = 0.008). Incidence rates among women increased from 48.3 to 50.3/100,000 person-years (ESP 1976: 36.9-38.0), corresponding to a mean annual change of 1.23% (p = 0.028). Age-standardized mortality rates varied between 103.8 and 97.2/100,000 person-years (ESP 1976: 72.8-69.7) in men and between 38.3 and 42.7/100,000 person-years (ESP 1976: 27.8-29.3) in women. Conclusion: Age-standardized incidence and mortality rates of lung cancer in Hungary were found to be high compared to Western-European countries, but lower than those reported by previous publications. The incidence of lung cancer decreased in men, while there was an increase in incidence and mortality among female lung cancer patients
