Abstract:
Background The presentational flow chart “unwell adult” of the Manchester Triage System (MTS) occupies a special role in this triage system, defined as the nonspecific presentation of an emergency patient. Current scientific studies show that a considerable proportion of emergency room patients present with so-called "nonspecific complaints". The aim of the present study is to investigate in detail the initial assessment of emergency patients triaged according to the presentational flow chart "unwell adult".

Classical parametric statistical methods are based on several basic assumptions about data (normality, independence, constant mean and variance). Unfortunately, these assumptions are not always fulfilled in practice, whether due to problems arising during manufacturing or because these properties are not typical for some processes.

Poisson-Exponentially Weighted Moving Average (PEWMA) charts are one of the most frequently used control charts for monitoring count data.

One of the ways to tackle overdispersion is to use Poisson mixture distributions.

Abstract:
The assumptions and methods of analysis used to define the flexural strength and the available limit curvature of reinforced concrete columns sections are discussed. The results of cyclic moment-curvature analyses of a large range of reinforced concrete column sections, using cyclic stress-strain relationships for the steel and for the concrete, are outlined and the important variables and their influence on the available strength and curvature ductility are identified. Examples of design charts derived from these analytical results are discussed and a flow chart outlining the whole seismic re

Abstract:
This study offers a cross-national multilayered analysis of music flows between 1960 and 2010. Advancing on previous empirical studies of cultural globalization, it attends to the global and country level, while adding the individual level of music flows. Concretely, the authors analyze the international composition of pop charts in nine countries by (a) mapping trends, (b) comparing countries, and (c) conducting multivariate analyses. The results show that pop charts increasingly contain foreign music, with the exception of the United States. Explanatory analyses of foreign success confirm th

Total quality management (TQM) represents a strategic approach with a goal for better quality of the products through the integration of its techniques and tools for continuous improvement of the processes, increased satisfaction and fulfillment of the customers’ expectations. By introducing the TQM, better quality of procucts and services is obtained, costs are redusts, and greater market penetration is enabled. This research is aimed at the appreciation and understanding of the need for introducing TQM tools such as Pareto Chart, Control Charts, Flow Charts, Fishbone diagram, Checksheet, His

Abstract:
Summary This paper describes a simple and easy-to-construct numerical model for the calculation of the stabilized productivity of a hydraulically fractured well producing at a constant well pressure. The model takes into account both Darcy and non-Darcy pressure losses in the fracture. Dimensionless charts are presented that illustrate productivity improvement as a function of fracture length, fracture conductivity, and non-Darcy flow. For dimensionless fracture lengths in excess of 0.2, constant-pressure productivities are significantly lower than constant-rate productivities as predicted, fo

Abstract:
Pumping of fresh concrete is of utmost importance for concrete practice. Required pumping pressures are typically estimated based on design charts. However, with the increased use of chemical admixtures and the development of more flowable concrete mixtures, the accuracy of traditional design charts is questioned. In recent years, significant progress has been obtained in understanding the flow of the material in the pumping pipe, including the behavior of the lubrication layer near the pipe surface. In comparison with traditional design charts, this results in more reliable pressure predictio
