Hydro turbines
This presentation summarizes different types of hydro turbines classified based on how water acts on the turbine blades. Impulse turbines like Pelton and Turgo turbines use the kinetic energy of a high velocity water jet to turn the runner. Reaction turbines like Francis and Kaplan turbines use both the pressure and velocity of water. Francis turbines have fixed blades while Kaplan turbines have adjustable blades controlled by a servo mechanism. The presentation provides details on the working, typical specifications and applications of these common hydro turbine types to help select the optimal turbine for a hydroelectric project based on factors like head, flow, and output requirements.
Francis Turbine
The Francis turbine is an inward flow reaction turbine with radial discharge at the outlet. It is a mixed-flow turbine where water enters the runner radially and exits axially. Francis turbines are used in applications with medium head between 45-250 meters. They have medium specific speeds between 50-250 and a vertically oriented shaft. Francis turbines are widely used worldwide due to their high efficiencies between 80-94%. However, they also have high costs due to their complex design and cavitation can be an issue.
Pump storage Hydroelectricity
Pump storage hydroelectricity involves pumping water from a lower reservoir to an upper reservoir during off-peak hours using surplus grid power. The stored water is then released through turbines to generators during peak hours to produce electricity and meet higher demand. It helps balance the electricity load by absorbing excess power during low demand and releasing it during high demand periods. The largest pump storage plant is located in Bath County, Virginia and has an installed capacity of 3003MW from 6 turbines. It provides load balancing and frequency regulation services on the power grid.

pneumatic car jack
This project and implementation is very useful for long journey vehicle and this setup
helps to raise vehicle by using battery or engine power. An automatic pneumatichydraulic jack comprises a mini air compressor and automatic hydraulic jack to serve
as an on-vehicle tool where as the power of the battery on the vehicle is used to drive
the mini air compressor which compresses air to serve as its primary force. The air
enters an entry channel from an air inlet nozzle and passes to an air chamber via a
changeover valve to push a small air-oil piston, thus converting air pressure into
hydraulic pressure on the other side of the piston which enters into a large hydraulic
cylinder via a check valve and pushes a large piston. The downward movement of the
small air-oil piston causes engagement with and turns the changeover valve, thus
connecting the air chamber channel to an exhaust channel and the entry channel to the
storage tank channel which enables the oil storage tank to supply the small hydraulic
cylinder with oil under pressure and make the small air-oil piston move upwards when
the small hydraulic cylinder is filled with oil, the small air-oil piston turns the
changeover valve to connect the air entry channel to the air chamber channel again,
thereby completing the cycle. Such reciprocation converts the air pressure into
hydraulic pressure to push the big piston which in turn, jacks up the vehicle. To lower
the vehicle, an oil return screw is turned to allow the oil to return to the oil storage tank
via a return channel

Overall, the document provides an introduction to magnetic levitation wind turbines and their advantages over traditional horizontal axis designs.
Wind turbines Power Point Presentation
Wind turbines convert the kinetic energy of wind into mechanical or electrical energy. They consist of a tower, nacelle, rotor blades, generator, and other components. When wind blows, the rotor blades spin a shaft connecting to a generator inside the nacelle to produce electricity. Wind turbines require a minimum wind speed of 10-15 kph to function and automatically stop at 90 kph for safety. They come in both onshore and offshore varieties, with offshore turbines able to generate more electricity due to more regular winds but being more expensive to install and maintain.
DESIGN OPTIMIZATION OF WIND TURBINE BLADE
The objective of this project is to design a wind turbine that is optimized for the constraints that come with residential use. The main tasks of this project are:
> To study the design process and methodology of wind turbine
> Derive the Blade Element Momentum (BEM) theory then use it to conduct a parametric study that will determine if the optimized values of blade pitch and chord length create the most efficient blade geometry
> Analyse different air-foils to determine which one creates the most efficient wind turbine blade.
Wind Energy
Wind turbines convert the kinetic energy of wind into mechanical or electrical energy. Modern wind turbines are much more efficient than older designs, able to generate 250-300 kilowatts compared to older models generating around 30 kilowatts. Wind turbines work by using wind to turn blades which spin a shaft connected to a generator, producing electricity. They are mounted on towers to access stronger winds higher off the ground. While wind energy has advantages like being renewable and producing no emissions, it also has disadvantages like dependence on wind conditions and higher initial costs than some other energy sources.

Wind turbine blade design
This document discusses various design considerations for wind turbine blades. It begins by explaining how wind power is calculated based on swept area, wind speed, and air density. It then discusses different blade designs including the number of blades (one, two, or three blades are common), blade composition (wood, metal, fiberglass are options), construction techniques, airfoil shape to maximize lift and minimize drag, and twist and taper along the blade's length. Additional topics covered include tip-speed ratio, performance curves, the Betz limit on maximum energy capture, rotor solidity, pitch control mechanisms, and blade manufacturing processes. The document concludes by discussing classroom wind turbine blade challenge activities.

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.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
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.
