    An Effective Noise Adaptive Median Filter for Removing High Density Impulse Noises in Color Images

    Get PDF
    Images are normally degraded by some form of impulse noises during the acquisition, transmission and storage in the physical media. Most of the real time applications usually require bright and clear images, hence distorted or degraded images need to be processed to enhance easy identification of image details and further works on the image. In this paper we have analyzed and tested the number of existing median filtering algorithms and their limitations. As a result we have proposed a new effective noise adaptive median filtering algorithm, which removes the impulse noises in the color images while preserving the image details and enhancing the image quality. The proposed method is a spatial domain approach and uses the 3×3 overlapping window to filter the signal based on the correct selection of neighborhood values to obtain the effective median per window. The performance of the proposed effective median filter has been evaluated using MATLAB, simulations on a both gray scale and color images that have been subjected to high density of corruption up to 90% with impulse noises. The results expose the effectiveness of our proposed algorithm when compared with the quantitative image metrics such as PSNR, MSE, RMSE, IEF, Time and SSIM of existing standard and adaptive median filtering algorithms

    ObjectiveTo classify causeâ ofâ death (COD) for stillbirths occurring in a major referral hospital in Kumasi, Ghana.MethodsIn a retrospective review conducted between June 8, 2011, and June 12, 2012, detailed information was collected on all stillbirths delivered at Komfo Anokye Teaching Hospital in Kumasi, Ghana. Patient records were independently reviewed by investigators using the Perinatal Society of Australia and New Zealand’s Perinatal Death Classification system to determine COD for each case.ResultsCOD was analyzed in 465 stillbirth cases. The leading causes of death were hypoxic interpartum death (105, 22.6%), antepartum hemorrhage (67, 14.4%), hypertension (52, 11.2%), and perinatal infection (32, 6.9%). One hundred and fifty seven (33.8%) stillbirths were classified as unexplained antepartum deaths.ConclusionsThis evaluation of stillbirth in a busy, tertiary care hospital in Kumasi, Ghana provides crucial insight into the high volume of stillbirth in Ghana as well as its medical causes. The study demonstrated the high rate of stillbirth attributed to hypoxic intrapartum events, placental abruption, preâ eclampsia, and unspecified bacterial infections. Yet, our rate of unexplained stillbirths underscores the need for a stillbirth classification system that thoughtfully integrates the needs and limitations of lowâ resource settings as unexplained stillbirth rates are a common indicator of the effectiveness of a classification system.This study demonstrates the high rate of stillbirth associated with hypoxic intrapartum events, placental abruption, preâ eclampsia, and infection at a tertiary hospital in Ghana.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151859/1/ijgo12930_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151859/2/ijgo12930.pd

    Mediation Analysis Using the Hierarchical Multiple Regression Technique: A Study of the Mediating Roles of World-Class Performance in Operations

    The changing environment in an organization is forcing the organization to find a plan of integrated management framework and adequate performance measurement. Failure to plan basically means planning failure for the business. Finding the critical factors of quality management practices (QMP), themediating roles of the contextual factors of world-class performance in operations (i.e., world-class company practices or WCC, operational excellence practices or OE, company nonfinancial performance or CNFP), and the company financial performance would enable the company to facilitate the sustainability of TQM implementation model.This empirical study aims to assess how TQM—a holistic management philosophy initially developed by W. Edward Deming, which integrates improvement strategy, management practices, and organizational performance—is specifically implemented in the oil and gas companies operating in Indonesia. Relevant literature on the TQM, the world-class performance in operations (world-class company and operational performance), the company performance (financial and non-financial performances), and the amendments of the Law of the Republic of Indonesia concerning the oil and gas industry, and related research on how the oil and gas industry in Indonesia develops sustainable competitive advantage and sustainable development programs are reviewed in details in our study. The findings from data analysis provide evidence that there is a strong positive relationship between the critical factors of quality management practices and the company financial performance mediated by the three mediating variables, i.e., world-class company practices, operational excellence practices, and company non-financial performance

    This study titled The Effective Reading Speed class XI student of SMA Negeri 2 Tembilahan, Indragiri Hilir Regency. The problem in the study of how fast effective reading is, there any difference in the effective speed reading samples per group, per rank, per ethnic, per department and per gender is. The method used is descriptive method, with a total sample of 146 students in class XI SMA Negeri 2 Tembilahan. Data collection techniques to provide a test reading paragraphs exposition, consisting of four topics, such as Religion, Sports, Education and Environment. Every topic paragraph exposition consists of 60-160 wpm. The time process of reading paragraph is calculated by the researchers. After that, the students were given a multiple choice test consisting of five questions and five answers per topic selection. Then researchers correcting students' answer sh using the reading speed formula. To know there any difference is in the speed of reading per group of samples, per rank, per ethnic, calculated using ANOVA. Per department, and per gender, calculated using the t test. If ANOVA rejected, counting is used again with the t test.

Overall, it can be concluded that the effective speed reading class XI student of SMAN 2 Tembilahan Indragiri Hilir Regency has low category which is between 120-150 wpm

    Application of artificial neural network on vibration test data for damage identification in bridge girder

    Get PDF
    Structures are exposed to damage during their service life which can severely affect their safety and functionality. Thus, it is important to monitor structures for the occurrence, location and extent of damage. Artificial neural networks (ANNs) as a numerical technique have been applied increasingly for damage identification with varied success. ANNs are inspired by human biological neurons and have been used to model some specific problems in many areas of engineering and science to achieve reasonable results. ANNs have the ability to learn from examples and then adapt to changing situations when sufficient input-output data are available. This paper presents the application of ANNs for detection of damage in a steel girder bridge using natural frequencies as dynamic parameters. Dynamic parameters are easy to implement for damage assessment and can be directly linked to the topology of structure. In this study, the required data for the ANNs in the form of natural frequencies will be obtained from experimental modal analysis. This paper also highlights the concept of ANNs followed by the detail presentation of the experimental modal analysis for natural frequencies extraction
