Wind turbine by engr. ALI AKHTAR
Wind turbines convert the kinetic energy of wind into mechanical energy using rotor blades, a shaft, and a generator. As wind passes through rotor blades, aerodynamic forces cause them to spin and transfer the wind's kinetic energy into rotational mechanical energy. This energy spins the attached shaft, which then spins the generator to produce electricity through electromagnetic induction. In this way, wind turbines are able to harness wind energy and generate electricity in a three-step process of capturing wind energy, converting it to mechanical energy, and then converting that to electrical energy.

Modern wind turbines work by converting the kinetic energy of wind into mechanical power using rotating blades and a shaft connected to a generator. This mechanical power can power specific machinery or be converted into electricity. Wind turbines are mounted on towers to access stronger winds higher above the ground. While wind energy has advantages of being renewable and producing no emissions, disadvantages include intermittent wind availability and higher costs for offshore wind farms. The document provides details on various historical uses of windmills, components and operation of modern wind turbines, and considerations around onshore versus offshore wind power development.
Intro to wind energy
This document discusses factors to consider when installing a wind power plant. It compares wind power to nuclear and solar power, noting wind power plants are less complex and costly than nuclear but require more land and maintenance than solar. Key factors for installing wind power include wind resources, environmental impacts, economics, and grid connection requirements. The document also provides an example analysis for installing a 100MW wind farm in Visakhapatnam, India to help meet the region's energy needs.

How Wind Energy Works: An Introduction
Wind energy has been harnessed for millennia using technologies like sailboats and windmills. The document then explains how modern wind turbines work to generate electricity: the wind turns the rotor blades which spin the shaft, and the rotating shaft then turns the generator which uses magnets around a conductor to convert the mechanical energy of the spinning shaft into electrical energy that can power homes and businesses.
Wind vs solar
The document compares wind and solar power, noting that wind power is more plentiful and produces more energy than solar power on a national scale. While solar panels have a higher upfront cost, wind power tends to have lower costs and more available power from wind than solar. The best choice between wind and solar depends on location.
Make a Wind Generator presentation on how wind power works
On May 19, 2017, kids came to the Pasadena Public Library to make wind turbines that would generate electricity by turning the shaft of a hobby motor. We were inspired by a project we found at https://www.exploratorium.edu/snacks/.... But since making the light bulb come on didn't work (the motors we had either weren't strong enough or were too strong) we tested the amount of electricity generated a different way: with a digital multimeter. Kids still learned a lot about electricity, energy and wind power! Here's the presentation they watched to learn about these concepts.

K.L.
Wind energy is a renewable resource that will never run out as long as the sun continues to heat the Earth and cause temperature variations that generate wind. Wind turbines do not require traditional electricity sources to operate and have low maintenance needs, making wind a relatively cheap renewable energy option. Wind power also reduces greenhouse gas emissions and pollution compared to fossil fuels. Large amounts of electricity can be generated by wind turbines and fed into power grids.
Wind Energy
Wind power works by using wind turbine blades to harness the kinetic energy of the wind. As the wind flows over the airfoil shaped blades, it causes them to spin an electric generator to produce electricity. There are two main types of wind turbines: horizontal-axis wind turbines that have three propeller-like blades and vertical-axis wind turbines that have blades arranged vertically like an eggbeater. Wind power is a renewable source that reduces greenhouse gas emissions and has grown significantly in India and worldwide in recent decades as the costs of production have decreased.
WIND ENERGY (A SOURCE OF RENEWABLE ENERGY)
Wind energy provides a clean, renewable source of electricity. Wind is caused by differences in the heating of the Earth's surface by the sun, which causes air to move from higher to lower pressure areas. The growth of wind energy has been driven by declining costs as turbine technology has advanced, with larger and more efficient turbines able to generate electricity for less than 5 cents per kWh. While wind farms can power many homes, their development requires consideration of potential impacts on property values, wildlife, and noise levels through proper siting.
Wind energy
Wind is created by uneven heating of the Earth's surface from the sun. This causes warm air to rise over land and cooler air to move in, creating wind. Modern wind turbines convert the kinetic energy of wind into electricity. The most common design has two or three horizontal propeller-like blades atop a tall tower to capture wind energy and convert it to mechanical power. Large wind farms require average wind speeds of 13 mph while small turbines require 11 mph to efficiently generate electricity. Wind turbines were developed to provide renewable energy without emissions in response to energy shortages and environmental concerns.
Energy for the future
Generators use a moving magnet to push electrons along a wire, carrying the energy used to move the magnet as an electric current. Large generators in power stations supply electricity to factories, homes, and schools by converting huge amounts of energy used to turn them. This energy can come from various sources like steam turned by turbines using coal, gas, nuclear power or water from dams. Other renewable energy sources that can turn generators include wind power, hydroelectricity that doesn't pollute, and solar power from photovoltaic cells. Scientists are also researching fusion energy similar to what powers the sun.
Science Wind Power
Wind power has a long history dating back to its earliest uses for sailing boats and powering windmills in Persia around 500-900 AD. In the late 19th and early 20th centuries, thousands of farmers in the United States used windmills to pump water. Modern utility-scale wind power development began in the 1970s during the energy crisis, and growth accelerated in the early 1990s with improvements in wind turbine technology that increased reliability and lowered costs. Today, wind is one of the fastest growing sources of clean energy worldwide without producing greenhouse gas emissions.

This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

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.

Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
