Abstract: In developing countries load shedding for hours is very common. Generally, a small power backup source is utilized for necessary loads (emergency lights and emergency loads like fan and small cooler). Nowadays, grid-connected solar inverters that installed on the roof are widely utilized for backup power source in urban cities. Penetration of electric vehicles (EVs) are increasing, so charging of EVs battery through grid increase power grid instability. Solar PV based charging of EVs can be a solution for this problem. However, in the case of a charged battery condition, whenever battery has charged through the grid, the available power from solar PV modules remain unutilized and wasted. The proposed controllers modify the regular, low-cost home inverter into a PV grid-connected inverter that it also has the ability to utilize EV battery energy. It has better control strategy that guarantees the reliability of the power supply. Economy mode and reliable mode has been developed to improve standby power supply, it also maximizes utilization of PV energy. In addition, the customers, don’t need to buy a new expensive solar grid-connected inverter or any other devices to charge the EV battery if they already have a home-based inverter.

Stadium maintenance staff are one of those people who work hard to maintain the court correctly. One of the items that often require rework is the lines drawn on the court for maintenance of track or boundaries or even the entire court when it is football stadium etc. Besides, for indoor stadiums that host volleyball, basketball, tennis, etc., lines need to be drawn. Redrawing the court after each match is one of the major problems of concern. In such a scenario, a system is proposed that can draw the court lines autonomously. The objective of this research work is to present a design of an autonomous sports court drawing bot that can draw the linear lines automatically which can aid in the maintenance work of the sports stadium.

Abstract:  A smart way to solve the common problem of conventional door-locking system is proposed using conventional lock key methodology and it can be cloned and used by anyone. The proposed system is to make a secure door lock security system with two factor authentications. The user has to use Radio Frequency Identification tag. The tag’s data will be saved in a database. When the tag is read by the Radio Frequency Identification reader, the user has to input a pass code. After the pass code is entered, the user will receive a One-time password on his mobile device to unlock the door. The biggest advantage of proposed system is that the introduction of two factor authentication to gain the access to the door, which makes it more secure.

 

Managing Disaster with Blockchain, Cloud & IOT

 

Decentralized Application for Managing the Disaster with Block chain, Cloud &IOT

Abstract:  The paper presents a single integrated platform to connect all the organizations at the time of disaster to manage the disaster more efficiently and quickly. At the time of any disaster, the whole system is thrown into chaos and is disorganized. This leads to various mistakes and loss of communication between the parties who are responsible for managing the disaster. By providing a common platform for everyone to communicate, we can avert many mishaps and provide an effective relief to the disaster, allows us to reduce the cost of damage, helps us to save more lives and provide better support. We propose the idea of using cutting edge technologies to make this happen.

Ancient Money Systems:

  1. Barter system: The oldest form of money system, where goods and services were exchanged directly for other goods and services without the use of money.
  2. Cowrie shells: Cowrie shells were used as currency in many parts of the world, including Africa, Asia, and the Pacific Islands. The shells were valued for their beauty, durability, and rarity.
  3. Commodity money: This system involved the use of valuable commodities, such as salt, spices, and precious metals (such as gold), as a medium of exchange. The value of the commodity was determined by its scarcity and desirability.
  4. Grain-based systems: In ancient civilizations such as Egypt and Mesopotamia, grain was often used as a form of currency. Farmers would pay their taxes in grain, and grain would be used to pay wages to workers.
  5. Coinage: The use of coins as a medium of exchange emerged in ancient Greece and spread throughout the Roman Empire. Coins were typically made of precious metals, such as gold and silver, and their value was determined by their weight and purity.
