The rapid growth in the number of users in the field of web2.0 and web3.0 increases the need for the research of systems that provide access to transparent and secure person's identity. The lack of a unified system of this type forces services and governmental bodies to double-check the same information several times. This drives down user loyalty, requires additional labor costs of qualified specialists, and deteriorates security. A possible solution to this problem can be envisaged as the creation of the user's avatar in the blockchain. This research offers a solution with open-source code that decreases the time of deploying digital avatar management software. Its estimated reach is 1,595 billion users.

Index terms: blockchain, authentication, digital avatar, web3.0.

This paper presents a wind turbine parameter monitoring system that uses LoRa technology to monitor the parameters like air temperature, humidity, current, voltage, and light intensity. LoRa which stands for Long Range is a communication protocol that is under the Low Power Wide Area Network(LPWAN) which emphasizes long-range, low-power, low-bit rate wireless technology. The system is designed to provide proto-type data on the current state and to help optimize the performance of wind turbines. The system is based on a wireless network of sensors that are placed on the wind turbines and transmit data to a central server that incorporates the receiver.Upon receiving the data,.......

There has been a growing emphasis on Lean construction within construction research in recent years. Presently, the utilization of bibliometric analysis has gained prominence as an effective method for synthesizing findings from prior research endeavours. This approach facilitates the progression of current knowledge and the cultivation of a comprehensive and outcome-driven comprehension of the subject matter. While numerous scholarly investigations have delved into lean construction, there is a dearth of comprehensive research exploring the patterns of publications within the context of sustainability in this domain. Consequently, this study aims to address this......

The identification of flaws in manufactured goods is a crucial part of quality control in production. The manufactured products must satisfy two things viz., the industry specifications and customer specifications and accordingly the defects are classified. Defects through human inspection is too demanding and may always calls for an additional defect known as overlook defects. The advent of machine vision and learning made the human efforts simpler and the journey from human's to machines for quality control is proved to be a successful learning curve and highly demanding as well. The technique of machine vision and image annotation brought the change required in the field of quality control. This paper provides an insight of deep learning techniques for defect identification......

Globally, the demand for cheap energy source has risen as a result of population growth, urbanization, and industrialization. While the electricity consumption in emerging nations like Nigeria is rising, the supply, which is often derived from fossil fuels is diminishing, leading to an energy crisis and pollution. Thus, in order to cover both the present and future energy needs, it is necessary to investigate alternate or renewable energy sources. This study seeks to offer a broad overview of the economic design consideration, practical implementation parameters, and interconnections.......

This study focuses on the examination of the city-port relationship from an urban planning perspective, exploring whether it can be a harmonious or a rivalry relationship and whether it can contribute to the creation of local development and national development in general. Another vital dimension considered in this study is the technical and environmental aspects that play a pivotal role in shaping the dynamics between these two entities. A port city refers to a coastal city within the boundaries of which urban and port activities are developed and carried out. Although the complexity of city port dichotomy is not captured by this definition, as it is a powerful dipole, consisting of two interdependent spatial elements, the city and the port. The strong interaction between the two creates strong spatial links that form a relationship of major importance, which has drawn considerable research attention from various fields, with urban planners in particular keenly interested in this unique category of cities........

Nepal is an agricultural country and agriculture is the mainstay of national economy. Rice is a major staple crop of the country. During the year 2015/2016, rice contributed 44.75 per cent to the total edible cereal grain production in the country. Rice is a labor intensive crop and youth migration has created a situation of labor scarcity. Introduction of mechanization in rice cultivation is one of the best solutions to get rid of labor scarcity and increase production of rice. NRRP, Herdinath, Dhanusa has been carrying out different research works on use of different machineries and cultivation practices in rice farming. It carried out a study in 2015/016, 2016/2017 and 2017/018 on uses of different machineries in three replications with five treatments........

The mechanization of wheat farming in Nepal today has increased, making it an important component of the agricultural industry. Since the majority of farmers in Nepal still use conventional farming techniques, mechanization in wheat production is still in its infancy. But in recent years, the Nepal government has pushed for the adoption of cutting-edge agricultural technologies, such as farm mechanization, to boost the yield of wheat and other crops. The formation of the Directorate of Agricultural Research (DoAR), Tarahara under Nepal Agricultural Research Council played a significant role in pushing up the rising trend of productivity. The main objective of this research is to examine.......
