Data-driven classification and explainable-AI in the field of lung imaging
No full textDetecting lung diseases in medical images can be quite challenging for radiologists. In some cases, even experienced experts may struggle with accurately diagnosing chest diseases, leading to potential inaccuracies due to complex or unseen biomarkers. This review paper delves into various datasets and machine learning techniques employed in recent research for lung disease classification, focusing on pneumonia analysis using chest X-ray images. We explore conventional machine learning methods, pretrained deep learning models, customized convolutional neural networks (CNNs), and ensemble methods. A comprehensive comparison of different classification approaches is presented, encompassing data acquisition, preprocessing, feature extraction, and classification using machine vision, machine and deep learning, and explainable-AI (XAI). Our analysis highlights the superior performance of transfer learning-based methods using CNNs and ensemble models/features for lung disease classification. In addition, our comprehensive review offers insights for researchers in other medical domains too who utilize radiological images. By providing a thorough overview of various techniques, our work enables the establishment of effective strategies and identification of suitable methods for a wide range of challenges. Currently, beyond traditional evaluation metrics, researchers emphasize the importance of XAI techniques in machine and deep learning models and their applications in classification tasks. This incorporation helps in gaining a deeper understanding of their decision-making processes, leading to improved trust, transparency, and overall clinical decision-making. Our comprehensive review serves as a valuable resource for researchers and practitioners seeking not only to advance the field of lung disease detection using machine learning and XAI but also from other diverse domains
Measuring microfinance access : building on existing cross-country data
No full textGiven the acknowledged need for a new effort to expand the set of available data on direct access to financial services, including a focus on access by those at low income, Honohan provides a selective review of the diverse sources of data that exist and considers how best to build on them. He proposes a basic framework within which to consider the analysis of the interesting questions: (1) How does access affect poverty and productivity? and (2) What hinders access? The author discusses existing and potential contribution of household and business user surveys, surveys of providers and their regulators, and surveys of experts, and assesses their relative strengths.Banks&Banking Reform,Environmental Economics&Policies,Health Economics&Finance,Poverty Assessment,Governance Indicators

Diabetic foot ulcers (DFUs) pose a therapeutic challenge to surgeons, especially in developing countries where health care resources are limited and the vast majority of patients present to health facilities late with advanced foot ulcers. A prospective descriptive study was done at Bugando Medical Centre from February 2008 to January 2010 to describe our experience in the surgical management of DFUs in our local environment and compare with what is known in the literature. Of the total 4238 diabetic patients seen at BMC during the period under study, 136 (3.2%) patients had DFUs. Males outnumbered females by the ratio of 1.2:1. Their mean age was 54.32 years (ranged 21-72years). Thirty-eight (27.9%) patients were newly diagnosed diabetic patients. The majority of patients (95.5%) had type 2 diabetes mellitus. The mean duration of diabetes was 8.2 years while the duration of DFUs was 18.34 weeks. Fourteen (10.3%) patients had previous history of foot ulcers and six (4.4%) patients had previous amputations. The forefoot was commonly affected in 60.3% of cases. Neuropathic ulcers were the most common type of DFUs in 57.4% of cases. Wagner's stage 4 and 5 ulcers were the most prevalent at 29.4% and 23.5% respectively. The majority of patients (72.1%) were treated surgically. Lower limb amputation was the most common surgical procedure performed in 56.7% of cases. The complication rate was (33.5%) and surgical site infection was the most common complication (18.8%). Bacterial profile revealed polymicrobial pattern and Staphylococcus aureus was the most frequent microorganism isolated. All the microorganisms isolated showed high resistance to commonly used antibiotics except for Meropenem and imipenem, which were 100% sensitive each respectively. The mean hospital stay was 36.24 ± 12.62 days (ranged 18-128 days). Mortality rate was 13.2%. Diabetic foot ulceration constitutes a major source of morbidity and mortality among patients with diabetes mellitus at Bugando Medical Centre and is the leading cause of non-traumatic lower limb amputation. A multidisciplinary team approach targeting at good glycaemic control, education on foot care and appropriate footware, control of infection and early surgical intervention is required in order to reduce the morbidity and mortality associated with DFUs. Due to polymicrobial infection and antibiotic resistance, surgical intervention must be concerned
The Contribution of Shaikh Sharfuddin Ahmad Bin Yahya Maneri in Persian Literature: An Overview
No full textThe current study will examine the contribution of Shaikh Sharfuddin Ahmad bin Yahya Maneri (1263- 1381) in Persian Literature: An Overview. He is one of those distinguish scholar who has left ineradicable impact on the Muslim world through his noteworthy contribution to Sufism and Persian Language. During his age Indian clerics and mystics have rendered various contributions in Madaris and Khanqahs (Monasteries). Especially in the Middle Ages when Persian flourished in Madaris and khanqahs was the dominant language in India. The scholars and Sufi saints of this era have written on interdisciplinary subjects in Persian language and have wonderfully increased the collection of books in Persian. During this era an important and well-known name among them is Sheikh Sharaf-ud-Din Ahmad bin Yahya Maneri who wrote several books in different subjects and topics in Persian. Makhdoom Shaikh Sharaf-ud-Din Ahmad bin Yahya Maneri (1263- 1381) who is popularly known as Makhdoom-ul-Mulk Bihari and Makhdoom-e-Jahan is one of the most prominent Sufi saint of Bihar India during 13th and 14th century. His longevity in the field of writing was memorable among his contemporaries. His life was committed to religious and mystical works, which stimulate many scholars for serving the cause of Islam and contribution to Islamic learning and mysticism. This study will shows how Makhdoom Bihari has greatly influenced his era through his preaching and teaching of Islam in the way of Sufism and how his writings made a great contribution in Persian Language through his books Irshad al Talibeen, Sharah Adab al Murideen, Fawaid al Murideen, ‘Aqaid e Sharfi, Mirat al Muhaqqiqeen, Rahat al Qulub, Maktubat e Sadi, Maktubat e Do Sadi, Fawaid e Rukni, and Maktubat e Bist wa Hisht etc. This will also shows How his inner state, belief and observation, the dominance of the da\u27wah, the spirit of sincerity and compassion, the purity of the soul and the purity of the heart, and with all this, good taste and command over language has given Shaikh Sharfuddin Ahmad a high literary position among his generation, he also has developed a consistent style of expressing his thoughts and feelings this is specific only to him. His writings have a special place not only in Persian literature but also in Islamic literature and throughout the immense knowledge and facts, da\u27wah and reform; there will only be few things that are unparalleled in the literature and influence of language
Interleaved Multilevel Boost Converter With Minimal Voltage Multiplier Components for High-Voltage Step-Up Applications
No full textIn this article, a new interleaved multilevel boost converter (interleaved-MBC) is suggested with minimal voltage multiplier (VM) cells for high-voltage step-up applications. The interleaved-MBC is derived in such a way that the maximum utilization of the VM circuit operation can be achieved by the interleaved structure. Furthermore, compared to existing multilevel interleaved converters, the reduced number of capacitors and diode with equal voltage rating makes it more attractive. Similar to the existing multilevel converter, the feature of the interleaved-MBC provides the extension of the number of levels to achieve the necessary voltages just by adding similar capacitor-diode stages (single capacitor and single diode are required to increase the stage by one). The features like continuous input current, low-input ripples, high voltage conversion ratio, and reduced stress on devices make the proposed converter more suitable for the voltage step-up applications, such as dc link, hybrid distribution systems, hybrid photovoltaic systems, etc. The detailed analysis of the converter is carried out by considering the nonidealities in the power circuit. The operation of the interleaved-MBC is presented for continuous and discontinuous conduction modes with boundary conditions. The components selection criterion and the comparison of converters are presented with suitable discussions. The converter is experimentally tested, and the obtained results validate its performance and functionality.Manuscript received October 5, 2019; revised January 11, 2020 and March 20, 2020; accepted April 20, 2020.

Optimization of Kiln Feed Yield through an Analysis of Drilling and Blasting Parameters in a Quarry
No full textBlasting and drilling serves as an essential element for a mining operation to excel. Optimization of this operational aspect, requires consideration of various parameters that can be controllable or uncontrollable. To overcome the tediousness of analyzing each element selectively, some major parameters are outlined, and each blast is rendered relative to the other, by organizing the data from each blast design and integrating it in an empirical model called Kuz-Ram Model, which further can be used for predicting the impact of these parameters on fragmentation. Image analysis aids in validating the model credibility for using it as step forward for proposing alterations to the current practices in drilling and blasting area. Each image is processed with the help of Unmanned Aerial Vehicle, for safety and coverage of complete muck-pile. The study involves in depth focus on the impact of rock mass characteristic over fragmentation as well. Discontinuities, fractures, joint orientation and fillings are considered in designating each rock zone to specific class with the help of a geo-mechanical classification system called, Rock Mass Rating. To test the theory, an exercise is performed by separating two zones of variable rock mass properties and then the procedure is followed with empirical calculation, image analysis and supported by preferential loading to acquire a broad image of each zone fragmentation profile. Suggesting the variation in particle size distribution due to rock mass influence. The collected data and analyses shall serve as supporting tools for changes to blast design for obtaining desired fragmentation, which is synonymous to increasing the feed of kilns.Applied Earth Sciences | European Mining Cours
Mysticism and ethics in Islam
No full textIncludes bibliographical references.Standardized name for editor Bilal Orfali from the Library of Congress is: Urfahʹlī, Bilāl http://id.loc.gov/authorities/names/no2010019407The relationship between Sufism or Islamic mysticism and ethics is largely untilled land. Mysticism and Ethics in Islam attempts to survey this fertile area of investigation by attempting to come to a clearer idea of what is meant by the terms “ethics” and “mysticism,” both in relation to each other and to Islam. The articles in this volume do not have an eye so much on defining what mysticism and ethics in Islamic civilization are per se, as much as on coming to terms with the parameters and boundaries within which they have historically been conceptualized. As such, the book falls into four clearly demarcated time periods and foci: early, classical, late pre-modern, and modern and contemporary. Taken as a whole, this collection of contributions by leading specialists in their fields offer rich insights into some of the most important articulations of Sufi ethics to have animated the tradition, from past to present, in such geographically diverse regions and countries as Egypt, India, West Africa, Iran, Turkey, Russia, Central Asia, and China.Editors' introduction -- I.
