Central Bank Digital Currencies and Global Financial System: Theory and Practice is the perfect book for anyone interested in the impact of digital currencies on the global financial system, providing valuable insights and analysis on the topic. The topic of central bank digital currencies (CBDCs) is particularly relevant in 2023 because the use of digital currencies is rapidly growing around the world, and many central banks are exploring the idea of developing their own CBDCs. This book offers readers an opportunity to gain a better understanding of CBDCs, including their history, differences with cryptocurrencies, and the potential impact of CBDCs on the future of the financial system. The book’s didactic approach breaks down complex topics into easily digestible chapters, allowing readers to easily understand and follow the progression of digital currencies. For those interested in the future of digital currencies, the book offers a chapter on future research directions and concluding remarks. Central Bank Digital Currencies and Global Financial System: Theory and Practice is a must-read for anyone interested in the intersection of finance and technology. By exploring the evolution of digital currencies and their impact on the global financial system, this book provides valuable insights for policymakers, financial professionals, and anyone looking to understand the future of money.

Deafness is the invisible disability and the most common human sensory defects. It leads to difficult speech development poor educational and employment prospects of childhood. Comprehensive otologic and audiological evaluations are very much essential for aetiological assessment of hearing impaired children and management efficacy. The aetiology of deaf Children was diverse. Infection was the predominationg aetiologial factor (38%). The infections were: Measles (31.5%), Pneumonia in (26.2%), Typhoid (21.5%), Maternal Rubella (5.2%), Varicella (5.2%), Mumps (5.2%) and Meningitis (5.2%). 48% of deaf child had a parental suspicion of deafness below the one year of age. 35% had a positive family history and 32% had history of consanguinal marriage. The deaf children were managed with hearing device, among them 89% with hearing aid and 11% with cochlear implant 42.7% of child used hearing aid in both ears. The results of aided audiogram showde that, the gain after using hearing aid within 31-60 dB were 80%.10% in right ear, 71.10% in left year and 70.00% in both ears, so average gain after using hearing aid was 74% within 31- 60 dB.

The Wireless Sensor Network (WSN) gathers data through the sensor nodes from an area of interest and then processes it. The performance of WSN is, however, constrained by limited energy supply, requirement for collision free channel access and low bandwidth. This book focuses on the network layer of the OSI model and investigates some of the existing cluster-based hierarchical protocols. One of the problems of the existing algorithms is that the generated clusters are not uniformly distributed. Moreover, the optimum number of cluster formation is not guaranteed. We have proposed a hierarchical cluster-based algorithm called Iterative Cluster Formation (ICF). ICF forms the clusters iteratively and ensures a more uniform distribution of the cluster heads. ICF manages to control the placement of the cluster heads and guarantees an optimum number of cluster heads. ICF pursues a hierarchical clustering scheme which lowers the number of high-range transmission. Simulation results show that ICF performs better than the existing cluster-based protocols in terms of reducing the energy dissipation and increasing the network lifetime significantly.
