Microwave wireless power transmission
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite overhead conductors and underground cables that use high temperature super conductor. But, the transmission is still inefficient. According to the World Resources Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%,40% and greater than 40%. This is attributed to technical losses (grid’s inefficiencies) and theft. Any problem can be solved by state of the art technology. The above discussed problem can be solvedby choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.

Wireless power transmission
This document discusses wireless power transmission (WPT) and its various techniques. It provides an overview of WPT, its history dating back to Nikola Tesla's experiments, and the main types including near-field techniques like inductive coupling and far-field techniques like microwave and laser transmission. The key advantages of WPT are that it is more efficient than wired transmission and has lower maintenance costs. However, it also has disadvantages like distance constraints for near-field and safety concerns. WPT has applications in electric vehicle charging and delivering power to remote areas.
Wireless Electricity Transmission
Wireless Electrical Transmission as the name shows is the Transmission of Electrical Energy without wires to any place on Earth. Even to the most remote areas.
Wireless Transmission
This document discusses wireless power transmission (WPT), including its history, types, advantages, and applications. WPT allows the transmission of power from one place to another without wires or cables. There are different techniques used, such as magnetic resonance, which involves two coils tuned to the same frequency to transfer energy efficiently over greater distances with less power loss compared to traditional methods. WPT has benefits like eliminating wires and batteries, reducing maintenance costs, and helping address energy issues. However, it also faces challenges including limited range and higher initial costs.
WPT
Wireless power transmission involves transferring electric power from a power source to devices without wires. There are two main techniques: near-field techniques like inductive coupling and resonant inductive coupling, which work over short distances; and far-field techniques like microwave and laser transmission, which can transmit power over longer distances. While offering wire-free charging, wireless power also faces challenges of safety, efficiency, and cost that need to be addressed for practical applications.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
