Analyzing MRI segmentation based on wavelet and BEMD using fuzzy c-means clustering

Abstract: Segmentation of images means a great matter for the medical field treatment purpose. For the extraction of brain polyps, magnetic resonance image (MRI) processing contributes in a wide range. Usually it works in two ways: white matter and gray matter. The extraction of any type of issues helps in submissions of image segmentation like in medical report analysis, in preparation of radiotherapy, in formation of medical treatment etc. The main purpose of this paper is the Fuzzy C-Means (FCM) clustering exploitation by the help of Wavelet and Bi-dimensional Empirical Mode Decomposition (BEMD), as for the aim of improving the eminence of MR noisy images. To gain the best image segmentation method, in this paper the signal to noise ratio (SNR) rates were calculated by the data set of FCM clustering. As in the medical term of MRI segmentation, the experiment has done with synthetic WEB Images of brain that has verified the robustness and proved with efficiency with the applicable approach.

OkkhorNama: BdSL Image Dataset For Real Time Object Detection Algorithms

Abstract: In recent years, lots of researches are being conducted to interpret Bangladeshi Sign Language (BdSL) to the means that general people can communicate with people having a hearing impairment and reduce the verbal gap between them. Computer Vision is playing a vital role in this regard by developing a sustainable system to understand the signs for machine translations. To obtain optimal performance, along with the state-of-the-art CNN model, the requirement of a high-quality sign language dataset cannot be foreseen. In this paper, we have introduced a new image dataset OkkhorNama for Fingerspelled Bangladeshi Sign Language including all 46 signs with images over 12K. In each of the images, bounding boxes are carefully annotated and labeled. OkkhorNama contains images of high resolution, good quality, and adequate variation making it ideal to train object detection and localization algorithms that would perform well on real-world applications. The OkkhorNama dataset is compared with other datasets where OkkhorNama significantly outperforms other datasets in number and trained model performance. The dataset is publicly available for future research and development.

Reporting disclosure levels and compliance with bb, aaoifi, b/ifrs and sec of islamic financial institutions in bangladesh

Abstract: Compliance with financial reporting guidelines/standards promulgated by Regulatory Bodies has become a crucial issue of the day after a series of corporate debacles over a few years Regulators, professional bodies and researchers throughout the world have expressed their concern about the need for improved accounting pronouncements and compliance for providing better information than previously required for the preparation and presentation of corporate financial reporting The present study primarily focuses on the reporting disclosure levels and compliance with Bangladesh Bank (BB) Guidelines, Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) Accounting Standard, Bangladesh/International Financial Reporting Standard (B/IFRS) and Securities and Exchange Commission (SEC) Rules of Islamic Financial Institutions in Bangladesh Annual reports of (08) eight Islamic banks in Bangladesh have been examined for the year ending 2015 The results showed that the Islamic banks significantly followed the selected accounting guidelines/standards under review and did bring remarkable changes in the financial reporting practices made by the Islamic banks in Bangladesh The study attempted to examine empirically the levels of disclosure in corporate annual reports of Islamic banks in Bangladesh The study recommended increasing the level of compliance to make their financial reports more informative The study also tries to ascertain the regulatory necessary requirements in preparing the financial statements of banks under Islamic shariah and tries to display the compliance status of these banks with legislations The average compliance rate is 9328% for BB guidelines, 4654% for AAOIFI Accounting Standard, 4850% for B/IFRS and 5199% for SEC rules considering all required aspects of financial reports Compiling all of the requirements regarding financial reports of regulatory bodies will be helpful for banks to make financial reports convenient

Steady State Voltage Vulnerability and Stability Limit Analysis of Bangladesh Power System Using STATCOM as a Shunt Compensator

Abstract: Highest consistency of transmission line is very noteworthy due to enhancement of demand. Voltage stability and steady state limit are matter of great concentration as it plays an imperative function in Bangladesh Power System (BPS). In this paper we have used Modal analysis technique to scrutinize steady state voltage vulnerability and Continuation Power Flow (CPF) technique to assess steady state voltage stability limit in East-West Interconnector System (EWIS) of BPS using NEPLAN software. Inadequate reactive power in the power system causes voltage collapse which is mainly a local problem. This can be overcome by adding shunt compensative device like Static Synchronous Compensator (STATCOM). Inclusion of shunt FACTS (Flexible AC Transmission System) increases the stability and loading factor. The comparative result with and without STATCOM is also shown in BPS.

A Computational Investigation on the Control of Cavity-Induced Pressure Oscillations Using Sub-Cavity

Abstract: A computational investigation has been conducted to determine the effectiveness of a passive control technique of attenuating cavity-induced pressure oscillations in a confined two-dimensional supersonic flow. The passive control technique is achieved by fitting two flat plates near the front wall of a square cavity at Mach number 1.83 at the cavity entrance. The results showed that the flat plates attached near the front wall of the cavity, discouraged the formation of feedback loop which is widely believed to be the reason of cavity resonance. The resultant amount of attenuation of pressure oscillations was also dependent on the length of the flat plate used as an oscillation suppressor.
