In this paper we introduce a variation on Glaser's method for determining the shape of the failure rate function of a mixture. It has often been seen that the shape of the failure rate depends on the mixing parameter q. Our method provides an explanation for this phenomenon. We then illustrate our technique with the mixture of an exponential and a gamma density for all possible cases.

In the field of photogrammetry, the optical system, usually represented by the glass lens, is used for metric purposes. Therefore, the aberration characteristics of such a lens, inducing deviations from projective imaging, has to be well known. However, the most important property of the metric lens is the stability of its glass and mechanical elements, ensuring long-term reliability of the measured parameters. In case of a focus-variable lens, the repeatability of the lens setup is important as well. Lenses with a fixed focal length are usually considered as “fixed” though, in fact, most of them contain one or more movable glass elements, providing the focusing function. In cases where the lens is not equipped with fixing screws, the repeatability of the calibration parameters should be known. This paper derives simple mathematical formulas that can be used for measuring the repeatability of the focus-variable lenses, and gives a demonstrative example of such measuring. The given procedure has the advantage that only demanded parameters are estimated, hence, no unwanted correlations with the additional parameters exist. The test arrangement enables us to measure each demanded magnification of the optical system, which is important in close-range photogrammetry.

The penetration characteristics of EBW are primarily dependent on the main beam current (Iw), potential difference between the cathode and anode (voltage, V) and the welding speed (S). There are other influencing parameters like weld focus current (If), welding gun to work distance (GW) and beam oscillation.In the present study, the effect of work distance on focus current and on penetration of Ti6Al4V weld is studied using a 60kV, 30kW EB welding machine. Weld focus current is measured over a range of work distance and variation in its pattern is studied. Similarly, the variation of depth of penetration by varying the work distance and varying the focus current at a particular work distance constant are also analyzed.It is observed that, focus current is inversely proportional to the work distance and the variation in focus current per unit change of work distance is high in the shorter work distance region. The change in focus current and work distance affects the weld penetration and fusion zone geometry. For optimum penetration at a given work distance, the beam focus should be below the surface in keyhole welding. As the work distance increases, the penetration capacity of the beam decreases and maximum penetration is obtained in lesser work distance region.

It is commonly assumed that word order in free word order languages is determined by a simple topic – focus dichotomy. Analysis of data from Ancient Greek, a language with an extreme word order flexibility, reveals that matters are more complex: the parameters of discourse structure and semantics interact with information packaging and are thus indirectly also responsible for word order variation. Furthermore, Ancient Greek displays a number of synonymous word order patterns, which points to the co-existence of pragmatic determinedness and free variation in this language. The strict one-to-one correspondence between word order and information structure, assumed for the languages labelled discourse configurational, thus turns out to be only one of the possible relationships between form and pragmatic content.

Unstable angina is classified into new-onset, progressive, and angina at rest. Though hemostasis plays a crucial role in the pathogenesis of coronary artery disease, including unstable angina, limited data exist regarding peculiarities of fibrinolytic parameters in the above-mentioned types of unstable angina. Our study aims to investigate if there is a difference in the fibrinolytic state between the groups of patients with new-onset, progressive unstable angina in comparison with stable angina patients depending on medical history data, electrocardiographic and hemodynamic features. In our cross-sectional study, we recruited 93 coronary artery disease patients (mean age 62.32 (6.94) years, 41 males (44.1%)). They were divided into 3 groups: stable angina patients (n=22) (control), new-onset unstable angina patients (n=21), and progressive unstable angina patients (n=50). The groups were comparable by baseline characteristics. Blood samples were obtained before treatment onset. The concentrations of tissue plasminogen activator and inhibitor of plasminogen activator (type 1) were measured by the ELISA method. We registered 14 points at the admission department, particularly age, sex, body mass index, smoking, presence of the family history of cardiovascular disorders, ST-segment depression, T-wave variability, arrhythmias, left bundle branch blockage, heart rate, systolic and diastolic blood pressure, Sokolov-Lyon voltage criteria, and unstable angina type (new-onset or progressive). After comparison of fibrinolytic parameters’ concentrations among groups under investigation, we defined the main independent predictors among observed 14 parameters to create optimal regression models for assessment of fibrinolytic parameters concentrations. The groups under investigation differ significantly in concentration of tissue plasminogen activator (P<0.001) and inhibitor of plasminogen activator (type 1) (P<0.001). The tissue plasminogen activator concentration correlated significantly with ST depression (r=0.344, P=0.001), T wave variability (r=-0.233, P=0.02), systolic blood pressure (r=-0.675, P<0.001), diastolic blood pressure (r=-0.655, P<0.001), heart rate (r=-0.568, P<0.001) and clinical unstable angina subgroups (r=-0.706, P<0.001) as well as plasminogen activator inhibitor (type 1) concentration associated with age (r=-0.560, P<0.001), body mass index (r=-0.249, P=0.049), ST-segment depression (r=0.542, P<0.001), arrhythmia (r=0.210, P=0.03), systolic blood pressure (r=0.310, P=0.04), and clinical unstable angina subgroups (r=-0.406, P<0.001). An optimal regression models for tissue plasminogen activator and its inhibitor assessment included systolic blood pressure, heart rate, unstable angina subgroup (R2adj. = 65.0%, P<0.001) and systolic blood pressure, unstable angina subgroup (R2adj. = 42.7%, P<0.001), respectively. Thus, fibrinolytic state among unstable angina clinical types differs significantly independently on observed baseline clinical, electrocardiographic and hemodynamic parameters. This finding confirms the utility of Braunwald unstable angina classification.

A novel scheme is proposed to achieve beam focus by applying the method of embedded coordinate transformation[1] in this paper. The focus degree of electromagnetic waves is determined by the structure parameters in the transformation region. Theoretical analysis and simulating results are given to demonstrate that our design is feasible and practical, and might have some potential applications in solar cell plate. Moreover, full-wave numerical simulations do further work to confirm the theoretical analysis.

In this work, the results obtained in different tests performed on a Stirling cryocooler are shows, as well as a comparative analysis of these results with different load pressures. The prototype is a single-acting Stirling engine with a piston and displacer, which is used to liquefy air with helium as the working fluid; this is an integral Stirling (β-type). A three-phase asynchronous electric motor drives the Stirling engine and cooling, in the hot focus, is performed with a pressurized water circuit. In the cold focus are reached very low temperatures, around 75 K (-198 °C). The study has been developed at different load pressures of the working fluid and it shows a comparative analysis about the most important work parameters evolution. The parameters studied are the following: cooling water inlet and outlet temperatures, cold and hot focus temperatures, voltage and intensity consumed by the electric motor that drives the Stirling engine and quantity of liquid air obtained. The results show that it is very likely to use this configuration in industrial processes when they need cold and heat simultaneously.

The study of various aspects of social economy is stipulated by the fact that the focus of any economic system is the human being as the main object and the result of economic activity. The purpose of this paper is to cluster of social economies of the countries throughout the world with distinguishing the models of social economy for transition economies under globalization conditions. The results of research represent four clusters of social economy that prove validity of classification of 4 classic models of social economy: liberal, Scandinavian, corporatist, and Mediterranean. While the most developed countries have effective models of social economy, there is still no clear concept of social development for transition economies. This paper deals with social economy clustering of different countries with the view to determinate the place of transition economies in social metrics of global economy. Our study is limited to the number of countries – 40 countries of the world, mainly European, and timeframes – 2015 and 2016. The obtained results could be taken into account by governments when developing and implementing new social policy for transition economies considering the experience of countries with classical social models. The authors propose the main practical tools for transition social model. It is proposed to distinguish one more model of social economy – the transition model, typical for transition economies that implement social reforms and has some common features.

Effect of temperature to associated thermal physical characteristics is analyzed by establishing laser cutting model for stainless steel. Experiment shows the position of focus has an effect on cutting quality. Perfect positions of focus for different thickness are advanced. On this basis, applying the law of conservation of energy, where the total heat absorbed is equal to the sum of absorbed by melting and lost by conductive, heat onduction equation is set up. The function relation among cutting speed, thickness of plate and power is defined, which is verified to get perfect cutting quality in TRUMPF L3030. The formulations provide theoretical and practical support for actual laser cutting of stainless steel.

Abstract. Low streamflow as consequence of a drought event affects numerous aspects of life. Economic sectors that may be impacted by drought are, e.g. power production, agriculture, tourism and water quality management. Numerical models have increasingly been used to forecast low-flow and have become the focus of recent research. Here, we consider daily ensemble runoff forecasts for the river Thur, which has its source in the Swiss Alps. We focus on the low-flow indices duration, severity and magnitude, with a forecast lead-time of one month, to assess their potential usefulness for predictions. The ECMWF VarEPS 5 member reforecast, which covers 18 yr, is used as forcing for the hydrological model PREVAH. A thorough verification shows that, compared to peak flow, probabilistic low-flow forecasts are skillful for longer lead-times, low-flow index forecasts could also be beneficially included in a decision-making process. The results suggest monthly runoff forecasts are useful for accessing the risk of hydrological droughts.

Measurement of electron-optical parameters in TEM is important for two reasons: a) for automatic correction of focus, astigmatism and beam-tilt misalignment (autotuning) and b) for the accurate determination of the phase-contrast transfer function (PCTF) which is needed for a correct interpretation of high-resolution electron microscopy (HREM) images. This paper addresses specifically methods adapted to reach the second goal, stressing accuracy rather than speed and robusteness.

<p>Soil monitoring data can be no better than the quality of the monitoring system they stem from. Quality assessment (QA) of soil monitoring requires reliable and comprehensive quality assessment and quality control (QA/QC) schemes including (1) the selection of parameters and measurement quality related to (2) space and (3) time. It can be presented by a synoptic diagram with three axes based on a table with quality criteria. The two major quality parameters are the degrees of resolution (precision) and representativeness (bias), whereas the latter does not yet include parameter selection and soil sampling.<strong> </strong><strong></strong></p>As a result the quality of soil monitoring is usually greatly overestimated. This finding is supported by examples and practical recommendations are given. Since full representativeness for the three aspects of soil monitoring is a fiction in practice, their biases have to be quantified completely, continuously and reliably. The most important challenges are to quantitatively assess and control the representativeness of primary soil sampling and to improve it.

The success of hemodialysis (HD) treatments has been evaluated using objective measures of analytical parameters, or machine-measured parameters, despite having available validated instruments that assess patient perspective. There is an emerging interest regarding the use and relevance of patient-related outcomes (PROs). Electronic PROs (ePROs) involve the use of electronic technology, provide rapid access to this information, and are becoming more widely used in clinical trials and studies to evaluate efficacy and safety. Despite the scarce literature, this review suggests that ePROs are useful in providing a more customized and multidimensional approach to patient management and in making better clinical decisions in relevant aspects such as vascular access, duration and frequency of dialysis sessions, treatment of anemia, mental health, fatigue, and quality of life. The purpose of this review is to raise interest in the systematic use of ePROs in HD and to promote the development of studies in this field, which can respond to the gaps in knowledge and contribute to the implementation of the use of ePROs through new technologies, helping to improve the quality of health care.

AbstractThe paper is aimed at optimization of parameters of a copper plasma jet produced at the DPF-1000U device, in which the inner electrode face was conically shaped. Preliminary information was obtained by numerical simulations of the plasma jet creation for different copper cones with the use of the two-dimensional magneto-hydrodynamic code KAROL. The simulations suggested that the cone height in the range of 4–7 cm should ensure a good plasma jet quality. The experimental data delivered by means of a 16-frame laser interferometer and a four-frame X-ray pinhole camera fully confirmed this conclusion. In the paper, we demonstrate the results for a 5 cm height cone. The eroded Cu plasma, swept up by the deuterium plasma sheath, was accelerated axially and compressed to very small diameter (3 mm) with an electron density of 7 × 1018 cm−3. The Cu plasma jet achieved a velocity of 5 × 107 cm/s and reached in the period of about 230 ns a distance (length) of 7 cm. The above results prove a successful adaptation of the plasma focus device to the metallic plasma jet generator.

This paper was focus on the technical parameters matching model of laser direct metal deposition（DMD）forming. Based on a series of DMD forming experiments, the energy balance equation of laser power, beam radius, powder feeding velocity and scanning velocity was established which could provide a theoretical principle for parameter selection and optimizing.

Focus Group Discussions (FGD) is a renowned method for new food product development. This research used FGD followed by Quantitative Descriptive Analysis (QDA) and Affective Test (AT) to identify the sensory parameters of pineapple wine. Based on FGD, five parameters were found to be crucial for panelists while testing the wine, i.e. distinctive pineapple aroma, sweetness, alcoholic flavor, alcoholic taste and appearance. These five parameters were then used in QDA and AT to understand the expectation of panelists on the sample which was served. It was found that FGD, QDA and AT were effective in identifying the sensory parameters of pineapple wine

Saturation is commonly used to determine sample sizes in qualitative research, yet there is little guidance on what influences saturation. We aimed to assess saturation and identify parameters to estimate sample sizes for focus group studies in advance of data collection. We used two approaches to assess saturation in data from 10 focus group discussions. Four focus groups were sufficient to identify a range of new issues (code saturation), but more groups were needed to fully understand these issues (meaning saturation). Group stratification influenced meaning saturation, whereby one focus group per stratum was needed to identify issues; two groups per stratum provided a more comprehensive understanding of issues, but more groups per stratum provided little additional benefit. We identify six parameters influencing saturation in focus group data: study purpose, type of codes, group stratification, number of groups per stratum, and type and degree of saturation.
