This book focuses on recent developments in the field of two-dimensional nanomaterials for environmental applications. Due to their high surface area and tunable surface chemistry, two-dimensional nanomaterials are currently garnering great interest for environmental remediation applications. This book compiles contributed chapters from active international researchers dealing with the development of state-of-the-art two-dimensional nanomaterials in environmental applications such as water and wastewater treatment, adsorption, photocatalysis, membrane separation, desalination, deionization, environmental pollutants sensing/detection, carbon-dioxide capture and catalytic conversion, microbial treatment, and electrochemical remediation. Each chapter provides an essential and comprehensive overview of the recent advances in material development and application, giving special attention to preparation methods, tunning of physiochemical properties, surface and interface chemistry, structural porosity, assemblies integration for fabrication of devices, and their relationship with overall efficiency. It offers a valuable reference guide for environmental and materials scientists, engineers, and policymakers working towards environmental sustainability.

This book addresses the issues with privacy and security in Internet of things (IoT) networks which are susceptible to cyber-attacks and proposes deep learning-based approaches using artificial neural networks models to achieve a safer and more secured IoT environment. Due to the inadequacy of existing solutions to cover the entire IoT network security spectrum, the book utilizes artificial neural network models, which are used to classify, recognize, and model complex data including images, voice, and text, to enhance the level of security and privacy of IoT. This is applied to several IoT applications which include wireless sensor networks (WSN), meter reading transmission in smart grid, vehicular ad hoc networks (VANET), industrial IoT and connected networks. The book serves as a reference for researchers, academics, and network engineers who want to develop enhanced security and privacy features in the design of IoT systems.

This is an eye-opening and shocking insider¿s account of the rot within Indian cricket.

Augmented reality is a key technology that will facilitate a major paradigm shift in the way users interact with data and has only just recently been recognized as a viable solution for solving many critical needs. In practical terms, this innovation can be used to visualize data from hundreds of sensors simultaneously, overlaying relevant and actionable information over your environment through a headset. Semantic 3D reconstruction unlocks the promise of AR technology, possessing a far greater availability of semantic information. Although, there are several methods currently available as post-processing approaches to extract semantic information from the reconstructed 3D models, the results obtained results have been uncertain and evenly incorrect. Thus, it is necessary to explore or develop a novel 3D reconstruction approach to automatically recover 3D geometry model and obtained semantic information simultaneously.The rapid advent of deep learning brought new opportunities to the field of semantic 3D reconstruction from photo collections. Deep learning-based methods are not only able to extract semantic information but can also enhance fundamental techniques in semantic 3D reconstruction, techniques which include feature matching or tracking, stereo matching, camera pose estimation, and use of multi-view stereo methods. Moreover, deep learning techniques can be used to extract priors from photo collections, and this obtained information can in turn improve the quality of 3D reconstruction.

This book gathers selected papers presented at the International Conference on Innovations in Information and Communication Technologies (ICIICT 2022), held in Thailand during April 15-16, 2022. It presents the works on the intersection of the Computer Science and Communication Engineering. Topics covered in the book include communications engineering, Internet and web technology, computer and information science, artificial intelligence, data science and management, and ICT applications.

The focus of this book is on using the machine learning approaches to present various solutions for IoE network in smart cities to solve various research gaps such as demand response management, resource management and effective utilization of the underlying ICT network. It helps build the technical understanding for the reader.

March 1993. Mumbai was rocked by a series of bomb blasts. Unknown to most, Dawood Ibrahim, the mastermind behind the terror attack, had made several calls to the CBI. The don was desperate to prove his ''innocence'' by giving himself up, but with conditions. October 1999. The world''s very first case of cricket match-fixing led to the banning of six top Indian cricketers, including the then team captain. It was only in 2013, after the then commissioner of police revived the case, that a charge sheet was filed in a court of law. January 2002. Aftab Ansari-a notorious Dubai-based don responsible for kidnapping a shoe baron in 2001 with the help of Jihadi groups in Pakistan-was arrested just as he was about to escape Dubai on a forged passport to Pakistan. All these cases of life-threatening moments and unbelievable relief, involved the sharp investigative skills of an Indian Police Service officer then serving in the CBI. In his thirty-seven years of service, Neeraj Kumar neutralised several terror modules and decimated insidious organized crime syndicates spanning continents, working closely with Interpol, FBI, Scotland Yard and several national and international agencies. Much decorated and feted, he hung up his boots in 2013, after his last calling as Delhi''s police commissioner. He has now decided that the inside details of what have been some of the most fascinating crime stories of our times must not go unheard and untold. The book covers several high-profile cases cracked by him in recent years, including the arrest and deportation of Aftab Ansari, the main accused in the shooting at the American Center in Kolkata, the nabbing of Jagtar Singh Tara, the man behind Punjab CM Beant Singh''s assassination, and the arrest of Romesh Sharma, a Dawood henchman masquerading as a politician based in Delhi.

December 13, 2001: Pak-based terrorists carry out an audacious attack on the Indian Parliament killing eight security personnel and a gardener; all five terrorists are killed in their gun-battle with policemen deployed at the citadel of Indian democracy; the case is solved and all accused arrested within 72 hours. December 16, 2012: a 23-year-old physiotherapist is brutally gang raped in a moving bus in Delhi; the case is cracked within five days despite the lack of initial leads; a head constable loses his life in the line of duty during riots that follow the dastardly crime. In Khaki Files , Neeraj Kumar, a former Delhi Police Commissioner revisits many such high profile police cases of his career -from investigation of one of the biggest lottery frauds in the country to foiled ISI attempt to kill Tarun Tejpal and Anirudh Behal of Tehalka -bringing to light numerous achievements of the country''s police force, otherwise largely reviled and ridiculed.
