TL;DR: In this paper, the present scenario and future prospects of the energy sources for all the Indian islands are discussed, and data collected from different buoys of INCOIS are analyzed, and a location near Minicoy has been chosen for further study.
Abstract: The islands in the Indian Ocean as other remote islands are often challenged to meet their energy needs, and constantly getting electricity from the mainland is expensive. In this article, the present scenario and future prospects of the energy sources for all the Indian islands are discussed. Data collected from different buoys of INCOIS are analysed, and a location near Minicoy has been chosen for further study. This paper also provides the preliminary analysis of marine current energy feasibility in that location.

TL;DR: In this paper , the energy and freshwater production of the Open Cycle (OC) - OTEC plant at Lakshadweep is assessed based on the predicted sea surface temperature (SST) variations and experimental data collected from the OTEC at NIOT, Chennai.
Abstract: Ocean Thermal Energy Conversion(OTEC) is one of the most important renewable energy resources for islanders to meet the power and freshwater demand. It uses the temperature gradient between warm surface sea water and cold deep sea water. Challenges associated with the OC-OTEC are efficiency and economy. The efficiency of OTEC is mainly influenced by Sea Surface Temperature(SST) variations. The prediction of sea surface temperature is also a challenging task in a region with high SST variability. Hence an accurate SST prediction plays a major role in estimating the power and freshwater generation. Nowadays, Deep Neural Network(DNN) based prediction models are used for accurate SST prediction In this study, energy and freshwater production of the Open Cycle (OC) - OTEC plant at Lakshadweep is assessed based on the predicted SST variations of Lakshadweep and experimental data collected from the OTEC plant at NIOT, Chennai. First, the SST variation of Lakshadweep is predicted by developing prediction models using Recurrent Neural Network (RNN) based Long Short-Term Memory (LSTM) Deep Neural networks (DNN) using ten-year ECMWF satellite image monthly data. These predictive models are used to forecast OTEC power and freshwater. Finally, the net power and freshwater generations over a complete year have been evaluated for monthly as well as seasonal variations. The proposed methodology can be extensively used to optimize the usage of other renewable resources to satisfy the power and freshwater demand of islanders.

Abstract: The Lakshadweep Islands are well-known for their abundant fishery resources. Present study primarily focused on the systematic representation of IUCN (International Union for Conservation of Nature) Red Listed marine finfish landings of Chetlat Island of Lakshadweep archipelago (India). Monthly collections were carried out from September 2019 to February 2020 from the study area. A list of finfishes along with their scientific name, common name, family, and present conservation status was prepared. As per the IUCN Red List, out of 41 fish species identified, one species is ‘Endangered’ (EN), two species are ‘Near Threatened’ (NT), four species are ‘Vulnerable’ (VU), one species ‘Data Deficient’ (DD), 29 species ‘Least Concern’ (LC), and four species are ‘Not Evaluated’ (NE) categories. Information on the conservation status of fishes plays a significant role in fisheries science since it forms the basis for managing marine fishery resources.

TL;DR: In this article , the authors dealt with the different types of COVID-19 vaccine and their related distribution, it includes measures to ensure safe and secured distribution of the vaccine through block chain technology with the help of supply chain.
Abstract: The COVID-19 outbreak has impacted huge number of individuals all around the world and has caused a great economic loss all over the world. Vaccination is most effective solution to prevent this disease. It helps in protecting the whole community. It improves the human immune system and fights against corona virus reducing the death rate. This paper deals with the different types of COVID-19 vaccine and their related distribution, it includes measures to ensure safe and secured distribution of the vaccine through block chain technology with the help of supply chain. Any malfunction in the chain is identified by the trust value of the function point method and the value of the Markov Chain.

TL;DR: In this article, a step-by-step approach for wave and marine current ocean energy conversion is presented, depicting results based on experimental and field observations on device fundamentals, modelling approaches, project development issues.
Abstract: Ocean energy has many forms, encompassing tides, surface waves, ocean circulation, salinity and thermal gradients. This paper will considers two of these, namely those found in the kinetic energy resource in tidal streams or marine currents, driven by gravitational effects, and the resources in wind-driven waves, derived ultimately from solar energy. There is growing interest around the world in the utilisation of wave energy and marine currents (tidal stream) for the generation of electrical power. Marine currents are predictable and could be utilised without the need for barrages and the impounding of water, whilst wave energy is inherently less predictable, being a consequence of wind energy. The conversion of these resources into sustainable electrical power offers immense opportunities to nations endowed with such resources and this work is partially aimed at addressing such prospects. The research presented conveys the current status of wave and marine current energy conversion technologies addressing issues related to their infancy (only a handful being at the commercial prototype stage) as compared to others such offshore wind. The work establishes a step-by-step approach that could be used in technology and project development, depicting results based on experimental and field observations on device fundamentals, modelling approaches, project development issues. It includes analysis of the various pathways and approaches needed for technology and device or converter deployment issues. As most technology developments are currently UK based, the paper also discusses the UK's financial mechanisms available to support this area of renewable energy, highlighting the needed economic approaches in technology development phases. Examination of future prospects for wave and marine current ocean energy technologies are also discussed.

TL;DR: In this article, the authors describe the rationale and the engineering approach adopted for the development of technology for converting the kinetic energy in marine currents for large-scale electricity generation, which is the first commercially viable system for delivering power from marine currents.
Abstract: This paper describes the rationale and the engineering approach adopted for the development of technology for converting the kinetic energy in marine currents for large-scale electricity generation. Although the basic principles involved are relatively straightforward and well understood, being similar to those of a wind turbine, a practical and cost-effective large-scale system designed to extract the kinetic energy of flowing water has yet to be developed. This paper describes the research and development being undertaken through an industrial consortium with the aim of achieving this goal for the first time, i.e. to achieve the world's first commercially viable systems for delivering power from marine currents.
