S4 oman wind energy lidar sodar 2016
This document discusses wind measurement technologies like lidar and sodar. Lidar uses light to detect wind speed and direction at different heights, while sodar uses sound. Both work by transmitting pulses and analyzing the Doppler shift of the returning signals from aerosols to calculate wind velocity. They provide detailed wind profiles that help optimize wind farm operation and improve power generation efficiency. Case studies show lidar and sodar measurements correlate well with met mast anemometers.
Radar
Radar uses radio waves to detect objects by transmitting pulses that bounce off objects and return to a receiving dish. The time it takes and the strength of the returned signal can reveal an object's distance, direction, speed and other characteristics. Radar was developed secretly before and during WWII and is used for applications like air traffic control, weather monitoring, military defense systems and more. It works on the same echo and Doppler shift principles as sound but uses radio waves which travel far and are easy to detect.

Radar was originally developed for military use during World War II to locate enemy ships and planes. Today radar has many applications including weather monitoring, air traffic control, and police speed detection. It works by transmitting radio pulses and measuring their reflection off targets to determine the target's range, angle, and velocity.
radar-principles
Radar uses radio waves to detect objects and determine their range, altitude, direction or speed. It works by transmitting pulses of radio waves which bounce off objects and return a portion of energy to the receiving antenna. Radar was developed in the 1930s-1940s and has two main types - pulse radar which uses pulse transmission and continuous wave radar which uses continuous transmission. Key components of radar systems include the transmitter, antenna, receiver and display. Factors like signal reception, bandwidth, power and beam width affect radar performance.
Doppler effect
The Doppler effect is when the frequency of a wave is changed for an observer moving relative to its source. It is named after Christian Doppler who proposed it in 1842. The Doppler effect can be observed with the change in pitch of a train whistle as the train approaches and passes by. It is used in applications like radar to measure the velocity of detected objects, medical ultrasonography to measure blood flow velocities, police radar guns to detect speeding vehicles, and weather radar to track storm systems.

Doppler radar uses the Doppler effect of radio waves to detect how fast targets are moving based on changes in frequency of the echoes.
Speed Gun Radar Ppt.pptx
A radar speed gun uses Doppler radar to measure the speed of moving objects by detecting changes in frequency between emitted and reflected radio waves. It works by emitting a radio signal and detecting differences in frequency between the emitted signal and the signal bounced off the target, allowing the speed to be calculated using the Doppler effect. Radar speed guns are used by law enforcement to measure vehicle speeds and in sports to measure speeds like baseball pitches and tennis serves. They were invented in the 1940s and were first tested by the Connecticut State Police for traffic surveys.
Radiolocating
Radar uses radio waves to detect objects by transmitting pulses and measuring the time it takes for the reflected pulses to return. The first principles of radar were established by Nikola Tesla in 1917. Radar antennas transmit pulses that bounce off objects and return to the antenna, enabling a computer to calculate the object's distance and velocity. Electromagnetic waves reflect from objects depending on the wavelength and the object's size and shape. Radar systems must overcome unwanted signals like clutter and jamming to detect actual targets. Clutter appears in response to the radar's own signals while jamming involves outside radio signals that can mask targets.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

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.

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.

How Does Doppler Radar Work
- 1. How Does Doppler Radar Work? Get the Inside Scoop on How This Important Weather Tool Works Doppler radar, also known as weather radar, has always been the subject of curiosity among people. How does it work? What purpose does it serve, and how does it detect the weather? We will dive into every detail of doppler radar to answer these questions, and more!
- 2. What is Doppler Radar? Radar is a system that uses electromagnetic waves to detect objects and measure distances. The word doppler comes from a physicist called Christian Doppler who discovered that sound shifts in frequency as the source of sound moves closer or farther away. So, this means that if a wave has an object moving towards it, its frequency will be higher than if it was stationary. It is also known as a Doppler shift. What does a doppler radar do? A radar can use electromagnetic waves to find out what the speed and direction of motion are for any object by measuring how they change with time. They also measure heights, lengths, widths and other distances based on these calculations. These measurements can help forecasters see whether there are storms coming or where wind speeds are located so they can issue weather alerts early enough for people to prepare for bad weather conditions.
- 3. The Purpose of Doppler Radar What is doppler radar, you may ask. It is a weather surveillance system that utilizes radio waves to detect precipitation, winds, and other phenomena. There are two basic types: one being a stationary type that transmits waves in all directions and measures wind speed and direction; the second is a mobile type that emits pulses of energy in pulses or continuous wave form in order to measure precipitation, winds, etc. What Does a Doppler Radar Do? Now we know what it does. What does it measure then?
- 4. How Does Doppler Radar Work? What is doppler radar and what does it do? A doppler radar is a type of weather radar that measures wind speeds and precipitation. It can also measure the direction, height and width of rain, snow or hail. What does a doppler radar measure? One important thing that a doppler radar measures is winds. If you are looking at an area with high winds and want to know if they are severe, the doppler radar will tell you how strong they are (i.e., whether they are over 55 miles per hour). The doppler radar will also tell you what direction the wind is coming from and where it's going to go (i.e., north or east). The Different Types of Doppler Radar There are three different types of doppler radar which help measure different things. The first type of doppler radar is WSR-88D or NEXRAD and it measures rain rate, wind speed and direction, temperature and humidity in addition to precipitation. The second type of doppler radar is
- 5. called TDWR or TEMPO and it measures rainfall rates over a very short period of time. The third type of doppler radar is called ASOS or AWOS. These two radars monitor aviation weather conditions such as visibility and cloud cover. What does Doppler Radar Measure? It Measures Rain Rate, Wind Speed and Direction, Temperature, Humidity and Precipitation: The National Weather Service uses these measurements to make forecasts by predicting what will happen next with the weather. The Advantages and Disadvantages of Doppler Radar Doppler radar is an important tool for meteorologists. What does a doppler radar do? It provides information about wind speed and direction, temperature, and more. However, it can take hours before a storm has enough energy to be detected by this weather tool. Other disadvantages include not being able to detect storms that are too low in the atmosphere or located near mountains or buildings. There are
- 6. some advantages of using doppler radar though! For example, a doppler radar may be able to detect rainfall from thunderstorms with little rainfall accumulation. When these types of storms occur, we need this type of technology because sometimes the heaviest rain occurs outside of where people live.
