    In this paper, a modified ratio estimator in the presence of tri-mean and interquartile range, for estimating the population variance is proposed. Having studied the estimator proposed by Yadav et al. (2017) where they made use of information on tri-mean and inter-quartile range of the auxiliary variable to improve the estimate and efficiency of the variance estimator for estimating the population variance. The bias and mean squared error of the proposed estimator were derived up to first order of approximation and conditions for which the proposed estimator more efficient than other estimators considered in the study were also established. Numerical illustration was conducted using Murthy (1967) and Singh and Chaudhary (1986) datasets. It was shown that the proposed modified ratio estimator perform better than some existing related ratio estimators

    Steganography is a fascinating topic that is unique from the everyday cryptography and system administration that most of us deal with. Steganography is a type of code that can be used to communicate covertly. We looked into steganography's theoretical and practical limitations. We used the LSB methodology to print out the picture steganography system enhancement to provide a secure communication method. This steganography computer software shows how to use any text format to hide any type of information. The capacity of this application to support any type of text is its crowning achievement. Since prehistoric times, man has yearned for the capacity to converse in a private manner. Steganography isn't just for military or espionage objectives, as evidenced by the recent boom in research into watermarking to safeguard intellectual property. Steganography, like cryptography, will become more important in the future for safe communication in the "digital world"

    Impact of Edge Detection Algorithms on Different Types of Images using PSNR and MSE

    Get PDF
    Edge detection is the process of detecting sharp changes in image brightness in a digital image. It aids in the recognition of an object and its shape in an image. As a result, edge detection plays a vital role in image processing, especially in domains like segmentation, image registration, and object identification. This paper is an attempt to study the impact of several edge detection algorithms such as Sobel, Prewitt, Robert, Kirsch, Robinson, Laplacian of Gaussian (LOG) and Canny. The three different types of images such as medical , natural and satellite images are considered for experiment. Performance measures used for comparison are Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR)

    Network Optimization and Network User Access Limitations Using Mikhmon Server at Diskominfo Palembang City

    Get PDF
    Technological advancements have a significant impact on how people live their lives and offer a variety of advantages and conveniences. This trend also applies to computer network technology, whose primary goal is to facilitate information sharing among users. Behind these benefits and conveniences, there are drawbacks as well. For example, it is simple for other users to discover what data is sent over the network and enter the network without authorization. The goal of this project is to create a system that uses an authorization mechanism to restrict network users. This system was created by combining various work systems between the Mikrotik router serving as the gateway router for guests logging into the network at DISKOMINFO Palembang City and the Mikhmon server. The Network Development Life Cycle is employed as a technique (NDLC). The server and router's ability to grant internet access for the used voucher code and the time limit's ability to bar users from the network because the time used has passed allows for the verification of the test results produced by the generated voucher code. This technology can help DISKOMINFO Palembang City with its issues with separating its internal network from user guest networks (guest users) and can build a secure network even though guests access the internet through the company's internal network

    Performance analysis of medical image compression using DCT and FFT Transforms

    Get PDF
    There is a high demand for image compression since it reduces the computational time, which in turn reduces the storage and transmission costs. Image compression involves reducing excessive and irrelevant data while maintaining reasonable image quality. Image compression techniques such as the Discrete Cosine Transform (DCT) and Fast Fourier Transform (FFT) are the focus of this study. These tools were selected because of their wide application in image processing; one example is JPEG (Joint Photographic Experts Group), which uses DCT for compression. A comparison is made between DCT and FFT, two compression methods implemented in MATLAB. CT and MRI images are used for an experiment, the quality of an image is determined by various parameters. To perform DCT the filter mask is used and a threshold is used for FFT to keep the top coefficient values. The experimental findings are compared and evaluated in terms of Peak Signal to Noise Ratio (PSNR) and Compression Ratio (CR)
