A Comparison Study on the Performances Of X , EWMA and CUSUM Control Charts for Skewed Distributions Using Weighted Standard Deviations Methods

In many statistical process control (SPC) applications, the ease of use of control charts leads to ignoring the fact that the process population of the quality characteristic being measured may be highly skewed. However, in many situations, the normality assumption is usually violated. Among the recent heuristic charts for skewed distributions proposed in the literature are those based on the weighted standard deviation (WSD) method. Thus, this paper compares the performances of certain WSD charts, such as WSD X , WSD Exponential weighted moving Average (WSDEWMA) and WSD Cumulative Sum (WSD-CUSUM) charts for skewed distributions. The skewed distributions being considered are weibull, gamma and lognormal. The false alarm and mean shift detection rates were computed so as to evaluate the performances of the WSD charts. The WSD X chart was found to have the lowest false alarm rate in cases of known and unknown parameters. Moreover, when parameters are known and unknown, the WSD-CUSUM provided the highest mean shift detection rates. The chart with the lowest false alarm and the highest mean shift detection rates for most level of skewness and sample size, n is assumed to be have a better performance

An EWMA Control Chart for Monitoring the Mean of Skewed Populations Using Weighted Variance.

This paper discusses the use of weighted variance (wv) in setting up the limits of the exponentially weighted moving average (EWMA) chart for the monitoring of the mean of a process from a skewed population. This chart, called the WV-EWMA chart hereafter, reduces to the standard EWMA chart when the underlying distribution is symmetric

Computations of the band structure and linear optical properties of methylammonium bismuth bromide and methylammonium galluim bromide using FHI-aims Code

Ab initio calculations for the Linear Macroscopic Dielectric analyses of CH3NH3BiBr3 and CH3NH3GaBr3 (having 8.33% dopant replacement percentage each) as possible replacements for the Lead based perovskite CH3NH3PbBr3 were done in this work using Perdew–Burke–Ernzerhof functional of Density Functional Theory as implemented by FHI-aims Code. Optimized lattice constants were calculated for CH3NH3BiBr3 and CH3NH3GaBr3 to be 9.10 Å and 8.27 Å respectively. The Lowest Unoccupied Molecular Orbital (LUMO), Highest Occupied Molecular Orbital (HOMO) and calculated band gap, Band Structure and Density of States (DOS) plots were made to analyse the band structures of these crystals and they were found to be metallic with a band gap of 0.00018636 eV and 0.00022286 eV for CH3NH3BiBr3 and CH3NH3GaBr3 respectively. The imaginary and real parts of the inter-band and intra-band contribution to the linear dielectric tensor within the e imagi Random Phase Approximation (RPA) of the optical properties of these perovskites were calculated and an average dielectric tensor of 3.1209467 and 2.789173 was found for CH3NH3BiBr3 and CH3NH3GaBr3 respectively. From the absorption data and dielectric tensor components calculated, both materials have an average absorption peak at frequency of 16.5373nm at 1.006567 MeV, 16.2040nm at 1.227600 MeV respectively, across all cubic planes

Audit of lower urinary tract endoscopic procedures in Borno, North-Eastern Nigeria

Background: Endourology which includes lower urinary tract (LUT) endoscopy, is an important component of standard urological practice worldwide. The objective of our study was to audit the LUT endoscopic procedures performed in Borno, a state in north-eastern Nigeria and share our experience.Methods: We, retrospectively reviewed the Lower urinary Tract endoscopies performed in Borno state over 9 years, from January 2012 to December 2020. Data related to LUT endoscopies were extracted from the patients’ clinical notes and operation theatre registers of the 2 focused hospitals in Borno where endourology procedures were performed (University of Maiduguri Teaching Hospital and Royal specialist hospital maiduguri) and then analyzed. Urology patients who did not undergone LUT endoscopy were excluded.Results: We analyzed the data of total sum of 201 patients for the 2 hospitals, which represented the sample size for the study. Mean age of patients was 47.2years, with male to female ratio of 3.5:1. Bladder tumor with or without haematuria (31.3%) was the commonest indication for LUT endoscopy, seconded by removal of ureteric double J stents (23.4%). Urethrocystoscopy (74.0%) was the commonest procedure performed predominantly under local anaesthesia, for both diagnostic and therapeutic purposes.Conclusions: We reported LUT endoscopies in Borno which was commonly indicated in bladder tumors presenting with or without haematuria. Urethrocystoscopy is the commonest procedure. As we get more endourology equipment in the public hospital many of our patients will benefit from these minimally invasive procedures in both lower and upper urinary tract diseases

VHF radar observations of the dip equatorial E-region during sunset in the Brazilian sector

Using the RESCO 50 MHz backscatter radar (2.33° S, 44.2° W, DIP: –0.5), at São Luís, Brazil, we obtained Range Time Intensity (RTI) maps covering the equatorial electrojet heights during daytime and evening. These maps revealed a scattering region at an altitude of about 108 km during the sunset period. The type of 3-m irregularity region we present here has not been reported before in the literature, to our knowledge. It was mainly observed around the Southern Hemisphere summer-solstice period, under quiet magnetic activity condition. The occurrence of this echo region coincides in local time with the maximum intensity of an evening pre-reversal eastward electric field of the ionospheric <i>F</i>-region. A tentative explanation is proposed here in terms of the theory of the divergence of the equatorial electrojet (EEJ) current in the evening ionosphere presented by Haerendel and Eccles (1992), to explain the partial contribution of the divergence to the development of the pre-reversal electric field. The theory predicts an enhanced zonal electric field and hence a vertical electric field below 300 km as a consequence of the EEJ divergence in the evening. The experimental results of the enhanced echoes from the higher heights of the EEJ region seem to provide evidence that the divergence of the EEJ current can indeed be the driver of the observed scattering region

Fungal Contamination of Some Poultry Houses in Kaduna State, Nigeria

The study was conducted to assess the level of fungal contamination of poultry houses with emphasis on Aspergillus species contamination of litter, feeders, drinkers and the housing materials. Ten swabs each from ten locations and materials (100) of the 10 poultry houses were collected for fungal isolation. A total of 126 fungi belonging to 5 genera were isolated from the different parts of the poultry environment viz; Aspergillus, Mucor, Candida, Rhizopusand Penecillium species with Aspergillus and Candida species having the highest frequency of isolation, 69 (54.76%) and 27 (20.93%) respectively. Three species of Aspergillus were isolated A. fumigatus (22), A. flavus (22) and A. niger (18). Fungi were isolated from all parts of the poultry sampled with a higher rate of isolation from the doors, window nets, roof and feeders. The presence of Aspergillus and Candida species which are important poultry pathogens i.e causing Aspergillosis, mycotoxicosis and Candidaisis indicates an economic threat the farmers as well as to the health of the bird

Effects of light intensity on Orthosiphon stamineus Benth. seedlings treated with different organic fertilizers.

The main objective of this study was to investigate the effects of varying light intensities and different organic fertilizers on the growth performance of O. stamineus seedlings through measurement of Relative Height Growth Rate (RHGR) and biomass production. Randomized Complete Block Design (RCBD) was used. Orthosiphon stamineus was arranged accordingly into three blocks or replicates. The three blocks represented the percentage light intensity. Block 1 (30% of light), Block 2 (50% of light) and Block 3 (100% of light). Each Block had four treatments and 25 plants of O. stamineus. The treatments were chicken dung, cow dung, oil palm empty fruit bunch (EFB) and control. The four treatments were arranged randomly in each block. Growth parameters measured were plant height, biomass (aerial portion, root biomass and total biomass within sixth month’s period. The 50% Relative Light Intensity (RLI) was better than 30 and 100% RLI. The chicken dung is better than oil palm EFB and cow dung
