Unmanned aerial vehicles for Internet of Things (IoT) : concepts, techniques, and applications
\"The 15 chapters in this book explore the theoretical as well as a number of technical research outcomes on all aspects of UAVs. UAVs has widely differing applications such as disaster management, structural inspection, goods delivery, transportation, localization, mapping, pollution and radiation monitoring, search and rescue, farming, etc. The advantages of using UAVs are countless and have led the way for the full integration of UAVs, as intelligent objects into the IoT system. The book covers such subjects as: efficient energy management systems in UAV based IoT networks, IoE enabled UAVs, mind-controlled UAV using Brain-Computer Interface (BCI), the importance of AI in realizing autonomous and intelligent flying IoT, blockchain-based solutions for various security issues in UAV-enabled IoT, the challenges and threats of UAVs such as hijacking, privacy, cyber-security, and physical safety\"-- Provided by publisher.

India and the Square Kilometre Array
The Square Kilometre Array (SKA), the world's next-generation radio telescope, is being designed by an international consortium. It will, once complete, deliver capability for a broader range of science than any other facility. Indian scientists and engineers have played a critical role in the definition of the SKA concept and its science case, in the design of the instrument and, hopefully, will do so in the construction and operation. This article describes the current status of the global project with a focus on India's role in the global collaboration.

Personality Traits and Work Engagement: A Case Study on Female Bank Employees in Banking Sector
The purpose of the present study is to explore whether there is any qualifying relationship between personality traits and work engagement, also, the level of work engagement and big five personality traits among female employees in Himachal Pradesh. Relevant data through questionnaire was collected from 150 female employees working in 3 different Public sector banks namely State Bank of India, Punjab National Bank and UCO Bank in the state of Himachal Pradesh. The results of the study specified that there was a significant positive relationship between work engagement and big five personality traits. Extraversion, Agreeableness, conscientiousness, and openness were significantly related to work engagement and its dimensions namely vigor, dedication and absorption whereas neuroticism was found to be negatively related to the work engagement and the three dimensions of it. The level of work engagement was high in public sector whereas extraversion, conscientiousness, neuroticism and openness were average except the agreeableness trait of personality was high

Telescope Manager for the SKA
India has been a significant contributor to the SKA project from 2009, with a special emphasis on the Telescope Manager, the central control system for the SKA Observatory. This paper describes the details of the design and early prototyping phases of the Telescope Manager work package, including the accompanying life cycle activities. It also traces the history of India’s involvement in the work on the Telescope Manager in various phases of the project, describing the contribution starting with the concept design to the currently ongoing construction phase, and looks at the road ahead. The details of the design and the outcomes of the prototyping and development contributed by India in each phase, are also included.

India and the SKA: An overview
The Square Kilometre Array (SKA) Observatory is a next-generation radio astronomy facility that has recently entered into the construction phase, after successful completion of the design and prototyping phases during 2013–2021. Planned to be operational by the end of this decade, the SKA is expected to revolutionise astronomy by allowing cutting edge explorations in an extremely wide range of science areas, while driving the growth of many important new state-of-the-art technologies. There are more than 10 countries currently participating in the international consortium to build this facility, which will be co-located in Australia and South Africa with the global headquarters in the United Kingdom. Indian scientists and engineers have played a significant role since the beginning: from the definition of the SKA concept and its science case, to some important aspects of the design of the instrument and the prototyping activities. India is now getting ready to join the construction phase of the SKA with a well defined proposal for technical activities spanning a few different areas of work. Along with this, Indian astronomers are busy refining their science case for the SKA and preparing in different ways to be ready for front line science with the facility as and when it is commissioned. All these activities are coordinated by the SKA India consortium, which currently has a membership of more than 20 institutions across the country. In this paper, we describe the current status of the SKA project, and focus on India’s role—past contributions, ongoing activities and future plans.

Progression of digital-receiver architecture: From MWA to SKA1-Low, and beyond
Backed by advances in digital electronics, signal processing, computation and storage technologies, aperture arrays, which had strongly influenced the design of telescopes in the early years of radio astronomy, have made a comeback. Amid all these developments, an international effort to design and build the world’s largest radio telescope, the Square Kilometre Array (SKA), is ongoing. With its vast collecting area of 1

, the SKA is envisaged to provide unsurpassed sensitivity and leverage technological advances to implement a complex receiver to provide a large field of view through multiple beams on the sky. Many pathfinders and precursor aperture array telescopes for the SKA, operating in the frequency range of 10–300 MHz, have been constructed and operationalized to obtain valuable feedback on scientific, instrumental and functional aspects. This review article looks explicitly into the progression of digital-receiver architecture from the Murchison Widefield Array (precursor) to the SKA1-Low. It highlights the technological advances in analog-to-digital converters (ADCs), field-programmable gate arrays (FPGAs) and central processing unit–graphics processing unit (CPU–GPU) hybrid platforms around which complex digital signal processing systems implement efficient channelizers, beamformers and correlators. The article concludes with a preview of the design of a new generation signal processing platform based on radio frequency system-on-chip (RFSoC).
