Abstract:
In economic statistical design of a control chart, the economic-loss function is minimized subject to a constrained minimum value of power, maximum value of probability of false alarms and average time to signal an expected shift. This paper is concerned with the optimum economic statistical design of the X bar chart when quality characteristic has non-normal symmetric distribution. We considered three types of distributions: Student distribution, standard Laplace distribution and logistic distribution. For each of these distributions, we calculated theoretical distribution of standardized sam

Abstract:
A bivariate diameter and height distribution yields a unified model of a forest stand. The bivariate Johnson system bounded distribution and the bivariate power-normal distribution are explored. The power-normal distribution originates from the well-known Box–Cox transformation. As evaluated by the bivariate Kolmogorov–Smirnov distance, the bivariate power-normal distribution seems to be superior to the bivariate Johnson system bounded distribution. The conditional median height given the diameter is a possible height curve and is compared with a simple hyperbolic height curve. Evaluated by th

Polymeric material such as low density polyethylene (LDPE) has been used for decades as insulating material. Any polymeric material will experience degradation after prolonged application of high electrical stresses.

Electroluminescence method (EL) is used to detect the breakdown voltages of thin film LDPE. This method utilizes a Peltier cooled electron multiplying charge coupled device (EMCCD) camera to detect the breakdown of the sample. Statistical

The empirical distribution of common stock returns is a subject of interest to many researchers, as it often determines the validity of theoretical models proposed in the economics and finance studies.

We explore the feasibility of fitting the empirical distributions of several financial series to these two systems of distributions. Both systems of distributions are highly flexible and capable of

This article examines the flexibility of the Johnson system of distributions by assessing its performance in terms of modeling crop yields for the purpose of setting actuarially fair crop insurance premiums.

In the 1920s, the English philosopher W.E. Johnson introduced a characterization of the symmetric Dirichlet prior distribution in terms of its predictive distribution. This is typically referred to as Johnson’s “sufficientness” postulate, and it has been the subject of many contributions in Bayesian statistics, leading to predictive characterization for infinite-dimensional generalizations of the Dirichlet distribution, i.e., species-sampling models. In this paper, we review “sufficientness” postulates for species-sampling models, and then investigate analogous predictive characterizations for

The effective diffusion coefficients for a single catalyst pellet were determined by numerical integration of the Johnson-Stewart equation for bimodal and unimodal pore size distributions assuming a transitional diffusion regime. The effectiveness factors of a spherical catalyst pellet were determined at various pore size distribution probability density functions. Using effectiveness factors the production rates were determined. The results showed that the effectiveness factor and production rate are sensitive to catalyst pore size distribution and diffusion coefficient.

Starting with the zero-square “zeon algebra,” the connection with permanents is shown.

A permanent trace formula analogous to MacMahon's master theorem is presented and applied. Connections with permutation groups acting on sets and the Johnson association scheme arise. The families of numbers appearing as matrix entries turn out to be related to interesting variations on derangements. These generalized derangements are considered

Abstract:
Outliers are unexpected observations, which deviate from the majority of observations. Outlier detection and prediction are challenging tasks, because outliers are rare by definition. A test statistic for single upper outlier is proposed and applied to Johnson SB sample with unknown parameters. The Johnson SB distribution have four parameters and is extremely flexible, which means that it can fit a wide range of distribution shapes. Because of its distributional shapes it has a variety of applications in many fields. The test statistic proposed for the case when parameters are known (Sriwastav

Abstract:
The recent listing of the Northern spotted owl (Strix occidentalis caurina) by the U.S. Fish and Wildlife Service as a threatened species (Federal Register 1990) raises heated debate concerning the long-term survival of the species and perceived economic cost to timber industry (Thomas et al. 1988). Long term studies of the owls's ecology are necessary to provide information needed for ecologically based management plans (Dawson et al. 1987). Much is already known about the natural and life history of the Northern spotted owl (Forsman et al. 1984, Gutierrez et al. 1984, Gutierrez 1985, Frankli

The subject of COVID-19 vaccines has generated debate across the globe as it has created a fecund ground for a plethora of dynamics such as vaccine diplomacy, misinformation, and struggle for dominance among global powers to mention but a few. Thus, the vaccine subject has taken-center stage in global discourses, resulting in developing and developed nations experiencing challenges in respect to purchase, transparency, and accountability in the administration of vaccines. The subject of vaccines in Zimbabwe has provoked public skepticism indicative of the existing trust deficit between governm

Abstract:
Cost distribution theory suggests that the costs to the median voter in a democracy of fighting an insurgency with firepower are relatively low compared to a more labor-intensive approach. Therefore, this voter will favor a capitalintensive counterinsurgency campaign despite the resulting diminished prospects of victory. Primary and secondary sources show that President Lyndon Johnson and his civilian aides were very much aware that, although they considered a main force—focused and firepower-intensive strategy to be largely ineffective against the insurgency in South Vietnam, it was political

In this paper, we address the secure KLJN key donation to vehicles. This KLJN key donation solution is performed lane-by-lane by using roadside key provider equipment embedded in the pavement. A method to compute the lifetime of the KLJN key is also given. This key lifetime depends on the car density and gives an upper limit of the lifetime of the KLJN key for vehicular communica

Abstract:
The finite element modeling and simulation of extremely high speed machining of Ti6Al4V alloy are presented in the paper. The Johnson-Cook’s constitutive model is used to describe the material behavior. The Johnson-Cook damage initiation criterion is used to predict the onset of damage due to void nucleation in ductile fracture. A damage evaluation law based on plastic strain energy and a fracture criterion combining the effect of different fracture mechanisms are proposed to model the progressive damage and fracture, respectively. Simulation results show that the predicted chip morphology agr
