Statistical Properties of Generalized Strain Criterion for Multiaxial Random Fatigue
1989
ABSTRACT Statistical properties of generalized criterion of the maximum shear and normal strains on the fracture plane have been presented, Functions of probability distribution and spectral density of the equivalent strain have been analysed on the assumption that a random tensor of strain state is a six-dimensional stationary and ergodic Gaussian process. The expected value and variance of the equivalent strain have been determined as well. From spectral analysis a new limitation has been derived for extension of some multiaxial cyclic fatigue criteria to random loadings. It is connected with the fact that in some cases the frequency band of the equivalent strain is greater than that for …
Prognostic Value of p53, p21/WAF1, Bcl-2, Bax, Bak and Ki-67 Immunoreactivity in pT1 G3 Urothelial Bladder Carcinomas
2001
pT1 G3 bladder carcinomas are heterogeneous with respect to tumor recurrence and progression. Whereas some urologists treat these carcinomas by repeated transurethral resections often followed by intravesical chemotherapy or BCG instillation, others recommend cystectomy after tumor recurrence or early cystectomy after the initial diagnosis. Our goal was to determine the prognostic value of p53, p21/WAF1, Bcl-2, Bax, Bak, and Ki-67 immunoreactivity in these tumors. There were 30 patients with a new histopathological diagnosis of pT1 G3 urothelial carcinoma based on a transurethral resection specimen. Representative sections of these specimens were examined for the above markers. All patients…
Comparison of body segment models for female high jumpers utilising DXA images
2022
In motion analysis of sport competitions, the question is often about the most convenient choice for defining the segment endpoints when no visible landmarks can be used. The purpose of the present study was to determine the location of the body centre of mass (CoM) of female high jumpers by using a high accuracy reaction board and two different segment models: Dempster, 1955, de Leva, 1996. Digitising the bony landmarks from the images of dual energy x-ray absorptiometry (DXA) and overhead digital camera were used to compare the digitising accuracy. The location of the CoM determined by a reaction board was 55.88 ± 0.52 % of subjects’ body height. The segment model of Dempster digitized fr…
Criminal networks analysis in missing data scenarios through graph distances.
2021
Data collected in criminal investigations may suffer from: (i) incompleteness, due to the covert nature of criminal organisations; (ii) incorrectness, caused by either unintentional data collection errors and intentional deception by criminals; (iii) inconsistency, when the same information is collected into law enforcement databases multiple times, or in different formats. In this paper we analyse nine real criminal networks of different nature (i.e., Mafia networks, criminal street gangs and terrorist organizations) in order to quantify the impact of incomplete data and to determine which network type is most affected by it. The networks are firstly pruned following two specific methods: …
Controlling false match rates in record linkage using extreme value theory
2011
AbstractCleansing data from synonyms and homonyms is a relevant task in fields where high quality of data is crucial, for example in disease registries and medical research networks. Record linkage provides methods for minimizing synonym and homonym errors thereby improving data quality. We focus our attention to the case of homonym errors (in the following denoted as ‘false matches’), in which records belonging to different entities are wrongly classified as equal. Synonym errors (‘false non-matches’) occur when a single entity maps to multiple records in the linkage result. They are not considered in this study because in our application domain they are not as crucial as false matches. Fa…
AUSTRIA: Winter Tourism and Sport Retail Most Significant Sport Business Fields
2017
The Austrian sport landscape has undergone many changes within the last decades. One of the biggest changes is that the private sport sector has emerged to be nowadays a major contributor to the Austrian economy. Sport economy in Austria accounts for 4% of the total economic value added and over 333,000 people are connected to workplaces within this sector. Furthermore, the private sport sector contributes to other sectors, for example in the development of new products or materials for the aviation industry. Compared to the total value added in the Austrian sport economy, winter tourism and sport retailers act as the strongest contributors. In this article ski lift operators are presented …
Mild OSA and arterial hypertension in the European Sleep Apnoea Database cohort study
2019
Background: Mild obstructive sleep apnoea (OSA) is highly prevalent; however its association with important clinical outcomes like arterial hypertension remains unknown. Aims: To investigate the association between mild OSA and hypertension in the European Sleep Apnoea Database (ESADA) cohort after adjusting for relevant confounding factors. Methods: A multicentric sample of 7995 adults from the ESADA cohort with simple snoring or mild OSA at PG or PSG was studied. We compared the predictive value of mild OSA (AHI 5- Results: Arterial hypertension prevalence was 37% in mild OSA (n=1566) compared to 22% in non-apnoeic snorers (n=793, p Conclusion: Our results suppport the hypothesis that mi…
La portada de la iglesia de las Escuelas Pías de Gandía. Su proceso constructivo y modulación arquitectónico-musical
2020
The facade of the church of the Pious Schools of Gandia has not attracted the attention of researchers. However, its conception has a great architectural culture and constitutes an essential work to understand its context, fundamentally, that of the theoretical treatises of the Renaissance. From this study it is wanted to value its architecture and that it is considered as an outstanding ingredient to know its period of construction in general and jesuit architecture in particular. For its understanding, its interpretation in the culture of contemporary architecture treaties and, especially, in the architectural-musical theory of Leon Battista Alberti will be necessary.. La portada de la ig…
Incorporating stand level risk management options into forest decision support systems
2018
Aim of study: To examine methods of incorporating risk and uncertainty to stand level forest decisions. Area of study: A case study examines a small forest holding from Jonkoping, Sweden. Material and methods: We incorporate empirically estimated uncertainty into the simulation through a Monte Carlo approach when simulating the forest stands for the next 100 years. For the iterations of the Monte Carlo approach, errors were incorporated into the input data which was simulated according to the Heureka decision support system. Both the Value at Risk and the Conditional Value at Risk of the net present value are evaluated for each simulated stand. Main results: Visual representation of the er…
