More than 122 participants from 28 countries attended the meeting.

This book is a collection of high-quality peer-reviewed research papers presented at Sixth International Conference on Recent Trends in Computing (ICRTC 2020) held at SRM Institute of Science and Technology, Ghaziabad, Delhi, India, during 3 – 4 July 2020. The book discusses a wide variety of industrial, engineering and scientific applications of the emerging techniques. The book presents original works from researchers from academic and industry in the field of networking, security, big data and the Internet of things.

Since the beginning of agricultural production, there has been a continuous effort to grow more and better quality food to feed ever increasing popula tions. Both improved cultural practices and improved crop plants have allowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders, to seek new technologies that will continue to allow us to produce more and better food by fewer people on less land. Both improvement of existing cultivars and development of new high-yielding cultivars are common goals for breeders of all crops. In vitro haploid production is among the new technologies that show great promise toward the goal of increasing crop yields by making similar germplasm available for many crops that was used to implement one of the greatest plant breeding success stories of this century, i. e. , the development of hybrid maize by crosses of inbred lines. One of the main applications of anther culture has been to produce diploid homozygous pure lines in a single generation, thus saving many generations of backcrossing to reach homozygosity by traditional means or in crops where self-pollination is not possible. Because doubled haploids are equivalent to inbred lines, their value has been appreciated by plant breeders for decades. The search for natural haploids and methods to induce them has been ongoing since the beginning of the 20th century.

Concern about the fate of waste products produced by a wide range of industrial processes has led to the realization that they may have potential uses and, therefore, value. In an effort to develop more sustainable processes and reduce waste storage, the use of waste as a resource has been gaining attention worldwide. Consequently, there have been a large number of studies aimed at utilizing such wastes. Conversion of Large Scale Wastes into Value-added Products discusses various selected classes of large-scale waste and their current applications and potential future applications. This book provides a snapshot of a continually evolving field, which includes both well-established processes and a drive toward developing strategies for new applications of wastes. The first chapter provides a general introduction to the area of large-scale waste utilization, including drivers for waste recovery, and secondary processes and products for waste reuse. Subsequent chapters discuss applications and potential applications in specific classes of large-scale waste: Various types of waste generated from different metal processing operations Waste generated by coal combustion, a major source of power generation that produces enormous quantities of waste Waste electrical and electronic equipment, important for recycling finite resources and reducing health and environmental risks Food waste, a significant and diverse waste stream with economic and environmental impacts The final chapter presents a general conclusion to the broad subject of waste utilization, summarizing the topics and addressing future trends in waste research.
