The comparative analysis of carrying capacity for construction elements of steel hall according to PN-90/B-03200 and PN-EN 1993-1-1
Przedstawiono por贸wnanie stopni wykorzystania no艣no艣ci oraz oceny bezpiecze艅stwa element贸w stalowej
hali. No艣no艣膰 element贸w wyznaczono na podstawie norm PN-90/B-03200 i PN-EN 1993-1-1. Analiz臋 przeprowadzono
dla przemys艂owej hali stalowej z transportem podpartym. Uk艂ad no艣ny hali stanowi膮 jednonawowe ramy, w kt贸rych slupy
po艂膮czone s膮 przegubowo z d藕wigarem kratowym i sztywno z fundamentem. Ekstremalne warto艣ci si艂 w g艂贸wnych
elementach konstrukcji (d藕wigar kratowy, belka podsuwnicowa, s艂upy) wyznaczono w programie Autodesk Robot
Structural Professional 2012. W celu miarodajnego por贸wnania wynik贸w analizy statyczno-wytrzyma艂o艣ciowej
wprowadzono stopnie wykorzystania no艣no艣ci element贸w zwymiarowanej zgodnie z normami PN-B i PN-EN.
Zastosowano regresj臋 liniow膮 do oceny trendu i rozrzutu wynik贸w oraz wyznaczono wsp贸艂czynnik korelacji.The aim of this paper was to compare rates
of utilization of capacity of steel structure elements calculated
according to the Polish Standard PN-90/B-03200 and Eurocodes
PN-EN 1993-1-1. The elements of steel hall were calculated
with the procedures ULS and SLS and the rates of utilization
of capacity of them were placed in tabular. Based on this
calculation the regression curves for all of analysed elements
and only for truss were done. It was proved that the rates
of utilization of capacity calculated according to Eurocode 3
increased in compare to the rates calculated according to Polish
Standard. This increasing was caused by changes in values
of partial safety factors of actions in EC0 and EC1. That can
lead to more safety designing of steel structure but more
expensive too
Probabilistyczny model wspieraj膮cy wczesne diagnozowanie autyzmu
Bayesian networks are recognized as a suitable tool for modelling diagnostic problems. The power of this modelling is that it can combine knowledge coming from different sources. For example, in case of medical domain, the expert knowledge can be merged along with the medical data. This paper presents a Bayesian network model for early diagnosis of autism. The model was built based on the medical literature and then was revised by two domain experts. Our tool is dedicated to parents that can perform an early diagnosis of their child before visiting a specialist.Sieci bayesowskie s膮 cz臋sto u偶ywanym narz臋dziem w rozwi膮zywaniu problem贸w diagnostycznych. Jedn膮 z zalet tego narz臋dzia jest mozliwo艣膰 艂膮czenia wiedzy pochodz膮cej z r贸偶nych 藕r贸de艂. Na przyk艂ad, wiedza ekspert贸w mo偶e by膰 po艂膮czona z danymi. W naszym artykule prezentujemy model sieci bayesowskiej wspomagaj膮cy wczesne diagnozowanie autyzmu. Model zosta艂 zbudowany w oparciu o literatur臋 medyczn膮, a nast臋pnie zweryfikowany przez ekspert贸w. Narz臋dzie, kt贸re stworzyli艣my jest dedykowane rodzicom, kt贸rzy mog膮 dokona膰 wst臋pnej diagnozy zanim skontaktuj膮 si臋 ze specjalist膮
Metabolic syndrome is associated with similar long-term prognosis in non-obese and obese patients. An analysis of 45 615 patients from the nationwide LIPIDOGRAM 2004-2015 cohort studies
Aims We aimed to evaluate the association between metabolic syndrome (MetS) and long-term all-cause mortality. Methods The LIPIDOGRAM studies were carried out in the primary care in Poland in 2004, 2006 and 2015. MetS was diagnosed based on the National Cholesterol Education Program, Adult Treatment Panel III (NCEP/ATP III) and Joint Interim Statement (JIS) criteria. The cohort was divided into four groups: non-obese patients without MetS, obese patients without MetS, non-obese patients with MetS and obese patients with MetS. Differences in all-cause mortality was analyzed using Kaplan-Meier and Cox regression analyses. Results 45,615 participants were enrolled (mean age 56.3, standard deviation: 11.8 years; 61.7% female). MetS was diagnosed in 14,202 (31%) by NCEP/ATP III criteria, and 17,216 (37.7%) by JIS criteria. Follow-up was available for 44,620 (97.8%, median duration 15.3 years) patients. MetS was associated with increased mortality risk among the obese (hazard ratio, HR: 1.88 [95% CI, 1.79-1.99] and HR: 1.93 [95% CI 1.82-2.04], according to NCEP/ATP III and JIS criteria, respectively) and non-obese individuals (HR: 2.11 [95% CI 1.85-2.40] and 1.7 [95% CI, 1.56-1.85] according to NCEP/ATP III and JIS criteria respectively). Obese patients without MetS had a higher mortality risk than non-obese patients without MetS (HR: 1.16 [95% CI 1.10-1.23] and HR: 1.22 [95%CI 1.15-1.30], respectively in subgroups with NCEP/ATP III and JIS criteria applied). Conclusions MetS is associated with increased all-cause mortality risk in non-obese and obese patients. In patients without MetS obesity remains significantly associated with mortality. The concept of metabolically healthy obesity should be revised
