8/5/2023 0 Comments Laser point measure![]() The above-described apparatus performs a fairly specialized test. ![]() Angular changes, on the other hand, will be detected by the laser beam profiler.įigure 1: Pointing measurement system to discern angular and linear pointing accuracy With this system any linear motion of the laser will be detected by the near field profiler, but will not appear in the far field due to the f-theta properties of the lens. The other detector in the far field is set up with a lens of a known focal length (e.g., 1 meter) with the detector positioned at the geometric focus. The first is set up as a near field profiler imaging the front aperture of the laser via a beam splitter. In order to measure the linear and angular pointing, the measurement system will comprise two detectors. It is good to know whether instability is coming from linear motion of the laser or from angular perturbations. This can be very useful if the measurement’s purpose is to determine the stability of pointing in an optical system. It is possible to design a fairly simple measurement system to separate these two components of pointing. The angular component is the tip or tilt of the laser beam altering the path from the parallel. This motion is normally 1:1, that is, if the laser is raised 1mm, the spot moves 1mm unless there is a magnification lens in the optical path¹. This is the motion that one sees when the laser is raised or lowered, translated right or left, or is subjected to some type of vibration. The linear component comes from the horizontal and vertical motion of the laser, perpendicular to the axis of propagation. ![]() There are actually two components to laser pointing and laser pointing stability, linear and angular, which combine to affect the beam’s position. Stability can be affected by a number of factors, internal and external to the laser itself, including physical motion, heat buildup, cavity instability, air currents, and many more. Pointing stability is a measure of how much the beam position drifts from the ideal target over time. Pointing accuracy is simply whether the laser points where it is supposed to. Laser pointing accuracy and pointing stability are defined as an angular value, usually in milli- or microradians (mr or μr). But there is more to this measurement and more that can be learned about the laser’s performance. For laser scanning applications the measurement may be made in different locations across the scan plane to ensure proper linearity of the scan. Most of the time the measurement is made by placing the beam profiler at some distance from the laser source and aligning the beam until it points to the ideal target. Beam profilers have the capacity to tell where the beam is located on the detector, and different types of profilers can do this with varying degrees of accuracy and precision. This is often a simple measurement of where in space a laser spot is focused or aimed, which is relevant to a number of laser applications from laser range finding to optical scanning, laser marking to building laser printers. ![]() Therefore, beam profilers are often used to verify the performance of lasers and optical systems to avoid problems caused by bad alignment or to streamline the manufacturing processes of these devices. One of the laser’s most useful properties is that it can propagate over great distances defining a straight line, and many optical systems are designed to exploit this property.

8/5/2023 0 Comments Red discus fishShould be sand or fine to medium grade, smooth-surfaced pebbles. The below table is recommended stocking levels for mature discus.ĭiscus like to forage for food near the bottom, the If you are keeping a larger number of juveniles together ensure that you rehouse them in other tanks as they mature. It’s also worth noting that it’s generally recommended to keep a minimum of 5 discus together. Low maintenance fish tank that doesn't need excessive water changes, we recommendħ.5 litres (2 gallons) rule when stocking your tank. To keep the water quality good and ensure you have a Housing Discus and Aquarium Fish Tank Set-up Tipsĭiscus may grow to be pretty big, requiring a 284 liter (75-gallon) aquarium or bigger when fully mature. Many people prefer to keep Discus in a separate aquarium from other species. Small to medium-sized catfish, such as Corydoras catfish, are also ideal tank mates, but keep in mind that Discus are still members of the Cichlid family and should not be housed with very small fish that may fit in their mouths since they may end up as a meal. Most serious enthusiasts do not mix discus with a wide variety of other species.Ī shoal of Emperor or Cardinal tetras, some loaches like the Clown Loach, and dwarf cichlids such as Balloon Blue Rams or Balloon Electric Blue Ram all make good aquarium companions.Īll of these fish can withstand the higher temperatures and low pH/hardness that discus require. If shy or submissive fish are unable to compete, they should be removed. Behavior/Compatibility for Discusĭiscus are typically gentle fish, although like cichlids, they may be aggressive toward one another, particularly when seeking to couple off and reproduce. They love calm water and are seldom encountered in places with strong currents or waves. Seasonal flooding causes dramatic variations in water level in some places.ĭiscus tend to concentrate among fallen trees along the coast, known as "galhadas." Natural Habitatĭiscus may be found throughout the lowland Amazon River basin and parts of its tributaries, notably the Rio Negro, in floodplain lakes and flooded woodlands. There are various color variants available now, and more are being created via selective breeding.Ĭaptive bred discus will couple up and spawn fairly easily although, it is not unusual for immature parents to consume the eggs, which appears to be more likely if other fish are present in the tank.įor the first several days after hatching, the young will feed on body mucus released by the parents until they begin free swimming. However the discus we provide are captivity bred and are more accepting of prepared foods and more tolerant to a wider range of water conditions which makes them much easier to keep.ĭiscus, however are still not a fish for novices instead, we recommend them for people who have prior experience keeping fish. Whether in a school or rainbow colored discus or a collection of just snake skins, this discus will stand out.At least three species have been recognized, while the legitimacy of multiple species' scientific names is currently being debated.ĭiscus have a reputation as being difficult to keep due to their specific water chemistry and food demands, and whilst it is true that wild caught discus can be difficult to keep. ![]() Discus are also appealing to collectors because of their calm, peaceful nature, and the pleasant coloring and patterns of a snake skin discus will enhance any tropical aquarium. A mature snake skin discus will reach a size of 8” long, and its body is almost as tall as it is wide. It has considerably full pectoral and dorsal fins that extend almost the full length of its body, which adds to the roundness of its body. The snake skin discus has a very round and flat body. The dorsal and pectoral fins are covered with a series of thinly lined striations as well.ĭiscus fish are popular for collectors because of their large body size, their appealing round shape, and their vibrant colors and markings. The head of the snake skin discus also has striations on it. Close to the fins, the striations become more broken and dot like. Their bodies are covered in a pattern of striations that are fine lines, most of which run horizontally. ![]() Snake skin discus can be blue, red, green, tan, or gold. ![]() Colors of snake skin discus vary widely according to the color of the fish used in breeding, but they are usually a solid color rather than multiple shadings. In the snake skin discus, the vertical stress bars common to discus found in the wild have been completely eliminated. The snake skin discus has a beautiful pattern as a result of crossbreeding multiple varieties of discus. 8/5/2023 0 Comments 98 ram pressure govenor sensor

I also made a catch can system which works nicely (there's already some oil at the bottom). So I changed all of those, and the only thing that what made a difference was the pcv valve. So, I thought there would be something wrong with one of these things: Everything OK, only thing was that the battery was low/over it limits so it had to be changed at some point before winter.īut after a few days, the same symptoms came back. They had done the basics: Plugs (Champion), oil (Shell Helix 5W-40) and filter (Mopar) + some extras also: Brake- and Coolingfluid change + emissions tests. I had the 72000km scheduled maintenance done in June and the car came out nice from the shop. Like when you put gaspedal to floor, it hesitates while, bogs a little and then starts to accelerate normal.And the same with the deceleration.When I take my foot off the pedal and do a motorbrake, it bogs and jerks. The second thing that became worse, was the driveability of the car.Ĭar started to jerk in acceleration and in deceleration. It cranks nicely but then it makes a odd sound, like it wouldn't be getting enough fuel/air or something.First I suspected the starter but it clicks In coldstarts, engine makes this weird noise.

Be aware of bus safety and school drop-off procedures as well. Since more students are walking and biking to school, you'll need to stay alert around schools and neighborhoods. If you drive just before the school day starts or after it ends, you'll likely encounter busy crosswalks and bus stops. Keep a safe distance from other vehicles and know when to swerve if there's an object in the road. ![]() Be on the lookout for pedestrians and turn your headlights on during dawn or dusk hours. Make sure you're staying alert during nighttime hours. The days get shorter in the fall, so you'll find yourself driving in the dark more often. Avoid deer on the roadways by slowing down during peak hours, paying attention to road signs and using your high beams to increase visibility when possible. Dusk comes in the evening hours when the Sun sets over the horizon, and the skies are gradually darkening. A collision with a deer can do severe damage to your vehicle. Dusk and dawn refer to different periods of the day. Deer are most active from October to January, especially during the dusk and dawn hours. Drive cautiously in wet conditions – that includes driving slower than you would on a dry road. Combine that with lower temperatures and you'll find that your tires may have less grip than they did during the summer months. Did you know wet leaves can be as slippery as ice? As the weather cools down, the rain picks up.

However, this issue is common to the other state-of-the-art approaches. The most dangerous is an attack with noise that can be handled only to some extent. The extensive experiments confirmed that the proposed approach resists the affine transformation, cropping, random point removal, and various combinations of these attacks. It can be used like this: tested np.random.rand (20,3) cloud np.random.rand (50,3) print inhull (tested,cloud) If you have matplotlib installed, you can also use the following function that calls the first one and plots the results. The watermark can then be extracted from the watermarked point cloud easily. It returns a boolean array where True values indicate points that lie in the given convex hull. An iterative closest point algorithm is performed after that to align the attacked watermarked point cloud to the original one completely. Convex hull: Computes the volume of the minimal convex enclosing. The scale and the initial rigid affine transformation between the watermarked and the original point cloud can be estimated in this way to obtain a coarse point cloud registration. 3Depict is designed purely for post-processing of 3D point data. A point cloud registration technique is developed, based on a 3D convex hull. A convex hull point co-ordinate file is then created using writeconvexhullxy() ''' if os. In this work, an alternative approach is proposed that solves these issues efficiently. import os import sys import numpy as np from scipy import spatial def xyconvexhull (inputxyfile): ''' Calculates the convex hull of a given xy data set returning the indicies of the convex hull points in the input data set. Unfortunately, they fail in the case of cropping and random point removal attacks. Most 3D point cloud watermarking techniques apply Principal Component Analysis (PCA) to protect the watermark against affine transformation attacks. 8/4/2023 0 Comments Feed us happy game![]() While Katniss sees herself primarily as someone who others can depend upon, both in and out of the arena, who would Katniss be if she didn't have to provide for and protect the people around her? As there becomes a likely possibility that she might win the Hunger Games, she lets herself ask this question:įor the first time, I allow myself to truly think about the possibility that I might make it home. As the Games near their climax, Katniss will risk her life against the other tributes in order to bring Peeta the only medicine that can bring him back from the edge of death. He's a whiz at "decorating cakes," sure, but he's really not very good with weapons (19.25). The daughter of a coal miner, Katniss is a far more skilled hunter and tracker than Peeta, who is the son of a baker. While her alliance with Rue is sadly short-lived, Katniss will also act as provider and protector of another tribute: her co-tribute from District 12, Peeta Mellark. Katniss explains that she teamed up with the girl "because she's a survivor, and I trust her, and why not admit it? She reminds me of Prim" (15.28). The two shared food, clothing, and companionship. Her protective instincts extend to her ally from District 11, the young girl named Rue. ![]() While Katniss's role as a provider originated within the context of her family, Katniss is a strong provider in the arena as well. Hunting, foraging, and providing for her mother and sister Prim are at the very core of her identity. Katniss is the stalwart rock of her family. I checked and double-checked the plants I harvested with my father's pictures. Many are edible, but one false mouthful and you're dead. ![]() I stole eggs from nests, caught fish in nets, sometimes managed to shoot a squirrel or rabbit for stew, and gathered the various plants that sprung up beneath my feet. It was slow-going at first, but I was determined to feed us. Katniss describes the process as follows: Filling her father's shoes, she became the chief cook and bottlewasher, bringing home the food and income that would save the family from starvation. While Katniss's mother was unable to cope with the loss, falling into a deep depression, Katniss stayed focused and took charge. Now that we know just enough about the heroine of The Hunger Games to fill out her Facebook profile, let's get down to brass tacks: Who is Katniss Everdeen? Who is she really? Katniss the ProviderĮver since the death of her father in a tragic coal-mining accident, Katniss has taken on the role of her family's head of household. Also: a certain guy named Gale.ĭislikes include: Haymitch Abernathy, tracker jacker stings, getting her leg hair waxed, and the family cat. Likes include: bows, arrows, and lamb stew. She's a volunteer tribute in Panem's annual Hunger Games, having taken the place of her younger sister in an act of heroic self-sacrifice. Katniss Everdeen is a teenage girl who lives in District 12, an impoverished coal-mining region in the country of Panem. Ladies and gentleman, a brief statement of the facts: 8/4/2023 0 Comments Hp 63 black ink![]() The empty cartridges are collected from consumers, businesses, charities, sporting clubs, schools, etc. Remanufacturing is an industrial process whereby spent inkjet cartridges are disassembled and cleaned, refilled, engineered to become "as new", fully tested, and then marketed as own-brand cartridges, competing on the basis of price and quality with new cartridges. It takes less energy and natural resources to remanufacture printer ink cartridges than it does to make a compatible ink cartridge. These cartridges are professionally cleaned, rebuilt, and refilled to meet OEM specifications. Whereas HP 63XL remanufactured ink cartridges are recycled cores from genuine HP 63XL F6U64AN and HP 63 F6U62AN cartridges. In addition, these printer cartridges can not be recycled and often end up in landfills where it can take thousands of years to decompose. These cartridges often come from overseas where it is tougher to enforce the intellectual property rights of the original manufacturer. These are newly built cartridges made from molds using subpar raw materials and components produced to look like the OEM original cartridges. HP 63XL Compatible cartridges are clones. What is the difference between HP 63XL Remanufactured Ink Cartridge and HP 63XL Compatible ink?
