You can jump to the separate sections using the links below as this article is quite lengthy: Add-ons will be marked as compatible after testing. UPDATE: We are currently updating this article to include full coverage of the latest X-Plane 12 released in September 2022. Note: All of the mods and files listed here work with all versions of X-Plane 11 including the Steam version and DVD/boxed versions. And that is where we will start our look at ten of the best free add-ons for X-Plane. Whether it is the particular aspects of individual cities, the coastline of a specific island, or the rough terrain offered by some of the world’s most majestic mountain ranges from the United States to the Himalayas, all are waiting to expand your experience of virtual flying. As are the many different landscapes and outside terrains, which aside from the cockpit controls themselves, are largely the most important aspect of providing realism to the user, you. What’s more, it isn’t just planes and aircraft that are available and waiting to make your simulated flying experience that bit better.Įven basic add-ons such as the full keyboard control commands for ease of use around whichever virtual cockpit you find yourself in are available. And most of the time they are free to download and utilize the easy-to-use drag-and-drop system of installation. If the package has more, you will need to download it to view them.Once you have installed your basic version of X-Plane you will now probably be looking to customize your experience and add to it by way of the best available, and free, add-ons. This list displays the first 500 files in the package. Please post your comments below - we love to hear feedback from users. We recommend the HD Mesh v4 from AlpilotX which can be downloaded here.ĭeveloper: The original package was compiled by Forkboy2 and built/converted and repackaged by Fly Away Simulation. This package works best with a high-quality mesh scenery add-on to really bring the scenery to life. If you find this useful, please consider donating to the original author - details can be found in the readme file inside the ZIP package. We found that users were willing to suffer longer download times instead of running lengthy batch conversions (JPG to DDS) themselves. The entire package has been "pre-compiled" or "built" - so there is no need to run any lengthy conversion before using it - simply download and install. Daytona Beach International Airport (KDAB)įlorida is full of general aviation airports and airfields due to its volume of tourism, especially for private pilots who want a quick sunny break in the Sunshine State.īe aware, this is a large download and may take a long time on most Internet connections.Some great starting airports to start from in Florida to experience the scenery: Gone are the default textures that are used globally - this brings true-to-life imagery to make your virtual flights (especially VFR) more realistic and enjoyable.

The package covers the entire state of Florida - from Tallahassee all the way down to Key West. ?The photorealistic scenery or Orthophotos have been sourced from satellite data and converted into a format that X-Plane understands using Ortho4XP. The package is compatible with X-Plane 12 and 11 and is complete with correct overlays including roads and autogen. A complete package containing photorealistic scenery for the entire state of Florida. You can even batch resize your files after you've got it set up.Īny software or registration is required for me to use this image resizer to 3000 x 3000 pixels tool. It will save you a lot of time compared to using the resize command one by one. Use the resize command if you need to resize numerous images. Although this method allows you to resize numerous images at once, it is not advised for use on a website. If tf is looking for a Numpy array, use tfimage np. You can shrink an image by selecting a percentage less than 100 and enlarge it by selecting a greater amount.Ī multi-threaded computer can also be used to resize an image. You have already converted the PNG file into an 'in-memory' representation of an image with Image.open() so you dont want to read another file in tf. You can also reduce or increase the percentage by providing a lower or higher number. Choose Tools > Adjust Size for all images and the size you want. In Photoshop, for example, you can use the Image Processor dialogue box to resize many images at once. There are a few strategies that can be applied in such instances. Multiple images cannot be scaled at the same time when using the resize image to 3000 x 3000 pixels tool. Is image resizer to 3000 x 3000 pixels tool safe to use? However, the visual quality will not suffer as a result of this procedure. Then, in a new file format, you can upload it. This will reduce the size of the image while maintaining its quality. You can save space on your computer and lower the file size by using the resize image to 3000 x 3000 pixels tool. To lower the size of a file, you can utilise the resize image to 3000 x 3000 pixels tool. No data has been added or deleted from this image. To put it another way, resizing an image without resampling only changes its size, not its data content. Resizing is a simple and painless procedure. You may then download the resized image by using the image resizer to 3000 x 3000 pixels tool. You have complete control over the file's size and format. You may resize an image to a certain size in pixels by using the resizer image to 3000 x 3000 pixels tool. Simply select the new size you want for the image by clicking the dimensions in DIMENSIONS option. An image's height and width can be adjusted to resize it. One interesting feature of PNG files is the ability to create transparency in the image, particularly a transparent background.If you need to resize an image to fit a specific frame or document, use the resizer image to 3000 x 3000 pixels in DIMENSIONS tool. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page. If you are having trouble opening PNG files, use our PNG to JPG, PNG to WebP, or PNG to BMP converters.Īlternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. PNG files are also easily viewable on all web browsers. Generally, PNG files will open in your operating system’s default image viewer. The benefits of using PNG are Plus, PNG is an open format that uses lossless compression. PNG also supports animations with better transparency (try our GIF to APNG). PNG images can have RGB or RGBA colors and support transparency, which makes them perfect for use in icons, or graphic designs. Portable Network Graphics (PNG) is a raster-based file type that compresses images for portability. There's an increasing expectation that "things on the web" should be if not free, at least at a minuscule cost. A 12 month subscription on Shutterstock will set you back a minimum of $348.Īnd people expect Techsmith to pay that kind of cost for them so that they can have "all you can eat" for a one off, lifetime payment of $199? A 12 month subscription on Storyblocks is $149 for images only. They are essentially sub-licencing them from other library sites like Storyblocks and Shutterstock and therefore paying those other sites for them. The thing that doesn't seem to be clearly understood is that for the overwhelming majority of these assets. Also, you won't find a decent sized media library, ANYWHERE, that will give you lifetime carte blanche to thousands of assets for a one off payment of $199. Make it $199 for a lifetime and it's guaranteed that they will. Make it $99 / year and Techsmith will probably lose money on the deal. In the future? I wouldn't rule it out.Ĭonsidering that this is an "all you can eat" deal out of a collection of about 400K assets (not the biggest collection on the web but hardly small), it's not awful value for heavy users of stock content. I expect that Techsmith still plans to make money on the deal but I don't think it'll be huge, gouging money.Īlso, you don't HAVE to pay the fee every year if you don't need the assets that year.And the ones that you have downloaded in previous years, you can keep using subject to the terms and conditions.Īm I planning to sign on? Probably not at this stage because I need only a limited amount of stock content, much of which I already have and the rest of which is unlikely to cost me that much per year, so I'll still be better off going elsewhere. You could get similar assets from other libraries (iStock, Shutterstock, Getty, Storyblocks, at least two of which are behind this collection) but I doubt that you'd end up paying LESS per asset that way, unless you used very few of the assets. The extra cost is for new and improved assets, many of which are externally sourced from existing libraries and therefore come at a cost to TechSmith. They aren't taking anything away from you. you DO still get the usual set of assets plus a few more. Where and how do you start? You need to ask yourself a number of questions to find that out. and do one big shopping trip will keep you in control of both your diet and your finances. Taking time on the front end to plan a menu, write out a shopping list, check for sales. This is because you have a plan and you are working it. Meal plans are a great way to save time and live in less stress. Instead of heading to the grocery store each and every day you can use that time to cook healthy and delicious meals. When you are flying by the seat of your pants every day it is much easier to buy frozen pizza bites rather than taking the time to make a real dinner for your family. You will also find yourself eating more “real food”. You will be left with fewer opportunities to impulse buy and you will be more inclined to save money simply because you aren’t eating based on your cravings. Going to the store with a shopping list once a week will save you money no matter what. There are a number of reasons why menu planning will be helpful. It is free and it will help you implement getting organized in the kitchen. So, basically, it is hard to go wrong when you add meal planning to your life! Scroll down to the bottom of this post for your free weekly meal planning printables. In general, meal plans also lend themselves to healthier eating which leads to a healthier “you”. Start slow and you will get to your finish line! It all adds up to better organization and saving money. If you are anything like me I get overwhelmed with new techniques that require too many new things on my part. Believe it or not, it is simple but I do suggest that you take it slowly and add one or two new strategies at a time. One question I know you have is, “How do I start meal planning?”. And do I need to mention that this is no fun? This is where having a weekly menu plan and a grocery list will go a long way to saving your sanity (and some money too!). I don’t know about you, but if my meal planning is off, a bunch of things are off! My budget tends to be a bit haywire, my diet goes out the window and every night I am running around trying to figure out what to feed people. Free Weekly Meal Planner With Grocery ListĮach week I sit down and make a menu plan for the week. In this sequel, you are trying to give your penguin upgrades that will launch them further through the map. I managed to hack some simple games offline, but now i would like to hack Learn to Fly 3.įirstly, I played that game on kongregate and i managed to get almost everthing done (4 medals left) Welcome friends, I am pretty fresh in Cheat Engine, I watched some YT videos and I wanted to check everything out.Learn to Fly 2 is an exciting sequel that came out just 2 years after the original penguin launching game, Learn to Fly. Now I found that it is available on steam, so I would like to hack it. I tried to change BP, sardines and Cash values but I cannot do it.įirstly I tried to find those values with option "exactly" and "all", I found them and I am sure that it is that. everytime something changed in game it showed same values in Cheat Engine. everytime I try to change them in Cheat Engine, nothing happens in game. Before anything happened in game, all values are reset to oryginal ones. Freezing doesn't help at all, any value is not acceptable by game and resets. I tried finding those values with increase/decrease unknown value, but at the end i was left with NOTHING. I am pretty sure they encrypted those values somehow and I really do not know how to do it. I tried do same thing with online version on kongregate with K-Melon browser but it was totally same. I would like to know how to do it for the future, maybe other games also encrypt those values. The game works offline normally, so its not that problem. Look around enough and eventually you'll either find or be lead to some class in the package "lbg.anticheatengine". SafeNumber), look at the assertValue function and you'll see exactly what the game is doing. TLDR: it has an unprotected value people are meant to find, and when that value is to be read from, it cross references the unprotected value with a couple basic encodings of the value. If something doesn't match up, it restores the value from the encoding and fires a "cheat detected" event. Modifying the as3 bytecode is the easiest solution, but even if that's not an option, it's still easy for someone with knowledge of assembly to bypass that protection. The unprotected value is trivial to find. Once you find where the assertValue function is, all you need to do is make it immediately return on entry.Get the Penguin Fly in the air and the space Learn to fly 3 After that, look at the assembly around instructions that access the value and see what matches up with the source code. In the third version of the series Learn to fly, you will flight up in the sky with the help of a penguin that slides horizontally. You’ll be able to change key elements of this character to improve it and fly even higher. You will have to explore the available options to gain more height and get farther from the ground as possible, thanks to different resources available than can be acquired or gained. This version of the game has 4 different modes, among them, the Story Mode, in which you will have to fly with the penguin to the space, so getting enough power and speed will be crucial to achieve the target. On the other hand, the player has to raise up with sufficient power with dead weights attached to the penguin the classic mode that allows to travel through the air in a horizontal position as in previous versions, but this time without mechanisms to slide. Likewise, there is the Sandbox mode in which it is possible to play with several modifications that allows to have a fun time too. It must be added, is a game fit for the whole family, works as an ideal way of distracting the mind for some minutes and having some real fun while trying to get to the space with the penguin.Īlso, while you advance in the different stages of the game, you can choose between the Help Packages to get extra points and other elements (In a list of 24) to start the match they can be combined and, of course, will help your efforts. You will play using your keyboard, with the arrows to move in the different directions and the space bar to get the boost you need.

Noise pollution from different mediums, such as industries and transportation, can negatively impact the overall health of the people. Occupational Safety Standardsĭecibels also have an immense effect on controlling and supervising environmental noise, especially when it comes to urban planning. So, let’s read about its contributions on a daily basis in different realms. It plays a key role in various daily scenarios, helping humans enhance their quality of life and well-being. Decibel (dB) Uses in Ordinary Routineĭecibels are an important unit of measuring sound power. For example, if an amplifier expands the input power of signals by the 10th factor, it will be said as a 10 dB gain. Attenuation and Gainĭecibels are used to measure attenuation (reduced intensity) and gain (increased intensity) of signals in audio systems and electronic circuits. The results are expressed in decibels or ‘dB SEL’ and are utilized to evaluate potential hearing loss. To ensure workplace safety and environmental noise analysis, sound exposure levels (SELs) are utilized to calculate sound intensity in a particular time period. This demonstrates that the signal out will remain with the reference level of 3 dB throughout that range. For instance, a speaker may offer a +/- (both positive and negative) 3 dB ranging from 50Hz to 20kHz. Frequency ResponseĪudio devices like headphones and speakers sometimes use decibels to label their frequency response in order to represent how they regenerate various frequencies. Likewise, if someone shouts in pain, the maximum sound pressure level will be 130 dB. The SPL levels you experience in your daily life may mostly range from an almost-silent whispering at 20 dB SPL to the immensity of pain, which is around 130 dB SPL.įor example, if you are whispering in your friend’s ear during a college lecture, those sounds will have the highest SPL range of 20 dB and not more than that. Sound pressure levels help measure sound wave intensity as it spreads in the air. No, it is not a mistake that you are reading about SPL again under this section in fact, it discusses this reference in depth. But, if the radio signal is weak with interference, you will experience a low SNR. If the radio signal is powerful and there is minimal interference, you will receive a high SNR. So, the signals from the station indicate the ‘desired signals,’ and unwanted noises, like interference, indicate the background noise. Imagine you are listening to a radio station. To understand the signal-to-noise ratio, here’s a simple example. It calculates the ratio of the intensity of the desired signal to the intensity of the background noise. In signal processing and telecommunications, the SNR is demonstrated in decibels. This reference is used to measure all the power levels in the circuits of electronic equipment and is denoted by ‘dBm.’ b. In the field of electronic systems, the power level is 1 mW (milliwatt). So, let’s explore some common reference levels in dB. Moreover, you must understand that the uses of these levels can be different, depending on the implementations and field. Reference levels are important as they offer a proper context and permit you to comprehend whether a sound is quieter or louder than the reference sound. To make more sense of decibel calculations, you need to have a reference point. Here, the dissimilarity between sound intensity will be 60 dB. This means the difference in the sound intensity will be 10 dB.Īnother scenario is that if the second speaker is 1 million times stronger than the first one, then: The output power has fallen to half the maximum or mid band power.įigures often quoted on attenuators designed to reduce the outputs on signal generators by measured amounts.Similarly, if the second loudspeaker is 10 times more powerful than the first loudspeaker, then: The output voltage has fallen to 0.707 of the maximum (mid band) output.ī. −3dB Commonly used for limits of bandwidth in amplifiers, indicating the points where:Ī. ☑dB The least noticeable change in audio levels, also used for the limits of bandwidth on high quality audio amplifiers. Commonly Encountered dB ValuesĠdB The reference level to which all +dB and −dB figures refer. Likewise losses due to circuits such as filters, attenuators etc. This can produce some very large numbers, but the total of individual gains expressed in dBs would be the sum of the individual gains: An advantage of using dBs to indicate the gain of amplifiers is that in multi stage amplifiers, the total gain of a series of amplifiers expressed in simple ratios, would be the product of the individual gains: Now you'll need to decide whether you want to fish in freshwater lakes or on the ocean. Keep in mind that players also buy both lures and chum with their own vocation badges and then resell them on the AH for gold, so you don't always have to buy them from a vendor. These are pricey, but one goes a long way, and often times someone else will do the chumming for you. Start with yellow lures and grab one of each chum type while you're at it (chopped squid, sardines, mackerel, roosterfish, pike, and regular old chum). The badges are currency that you'll spend on lures and chum at a Blue Salt Brotherhood NPC. Once you've hit 10,000 proficiency, the sport fishing fun begins! At this point you'll have built up quite a stack of vocation badges (you'll earn three for each bait fish you catch, and you'll be catching a couple thousand of them before you hit 10K). On Tahyang, the price fluctuates, but I can usually find stacks of 100 worms for anywhere from three to five gold. Normally I find it quicker to buy bait from other players. You can buy seed bundles from the AH, or you can make your own bundles if you have access to a farmer's workstation on player-owned property. You can craft these as well, but you'll need to plant and harvest seed bundles to do so. Once you've got your rod, you'll need some worm bait. If you don't have the base materials, you can either buy them off the auction house or grow/mine them yourself. Once you've made these sub-components, make the final rod at the handicraft kiln. You'll need to make a sharp fishing hook at the kiln (base material iron ingot refined from iron ore), a bamboo fishing pole frame at the carpenter's bench (base materials bamboo stalks and wool or cotton fabric), a wooden reel at the carpenter's bench (base material lumber refined from logs), and basic fishing line at the loom (base materials cotton and wool). You may also save some time if there's an auctioneer NPC and a mailbox nearby. You won't get very far without a fishing rod, and why not use this opportunity to acquaint yourself with ArcheAge's crafting mechanics if you haven't already? Sure, you could buy a bamboo pole via the auction house, but then you'd be giving your hard-earned gold to another player when you could spend 10 minutes equipping yourself and scarfing up XP and crafting proficiency in the process.įind the nearest crafting area on your map and make sure it has a tailoring loom, a handicraft kiln, and a carpentry workbench. If you're not in it for the long-haul, you can opt for the usual/casual MMO fishing experience that in this case amounts to auto-casting for both fishing proficiency and leveling XP. If you're so inclined, you can make a virtual career of it as well as quite a pile of gold via high-level sport fishing. Getting started takes some doing, though, as ArcheAge's fishing mechanics are undoubtedly the most robust I've seen in an MMORPG. meatspace thing, is that this time I very much look forward to a couple of hours of angling and the lazy in-game lifestyle that fits it like a glove. One of the key differences, apart from the obvious digital vs. Remember, if there is a loss of breath sounds in an area, it probably indicates a pneumothorax, or a collapsed lung, in which there is no air movement in that area. Pleural rubs come and go, are not altered with coughing, can usually be localized to a specific location on the chest wall, and will stop when the patient holds their breath. The sound of pleural rubs occurs every time the patient inhales and exhales. It can be described as the sound of walking on fresh snow or rubbing leather together. The sound may be continuous or broken and creaking or grating. This is often heard in pleurisy, or inflammation of the tissues that lie in the lungs and chest cavity. Pleural rubs occur when two inflamed pleural surfaces rub against each other during respiration. Listen to the sound of course crackles in a patient with pneumonia: They are usually caused by mucus in the bronchi. Coarse crackles are often heard just in certain spots in the lungs, possibly only on one side or in different spots on both sides. They are described as a bubbling sound, as when pouring water out of a bottle or like ripping open Velcro. As the fluid fills the lungs more, fine crackles can be heard closer and closer to the top of the lungs.Ĭoarse crackles sound like coarse, rattling, crackling sounds that are louder, longer, and lower in pitch than fine crackles. Fine crackles usually start at the base of the lungs where there is fluid in the lungs. Fine crackles sound like wood burning in a fireplace or cellophane being crumpled. Fine crackles are high-pitched, brief, discontinuous popping lung sounds. They are broken down into fine crackles and coarse crackles. Late inspiratory crackles may indicate pneumonia, CHF, or atelectasis, a complete or partial collapse of a lung or lobe of a lung. Early inspiratory and expiratory crackles are heard in chronic bronchitis. Crackles can be heard on inspiration and expiration. Previously termed rales, crackles are sounds that are heard in the lung field that has fluid in small airways. Listen to the following stridor lung sounds: Stridor can indicate a medical emergency if not enough oxygen is able to get through the airways. You may frequently hear stridor in children, as they are more likely to choke and more likely to get childhood infections like croup. Stridor can also be heard in a person with an infection, swelling in the throat, or laryngospasm. Stridor is caused by something blocking the larynx, such as a person choking on an object. Air is moving roughly over a partially obstructed upper airway. When listening with a stethoscope, if the sound is louder over the throat, it is stridor, not wheezing. Stridor is a high-pitched musical sound heard on inspiration, which resembles wheezing. This is often heard in pneumonia, chronic bronchitis, or cystic fibrosis. Rhonchi occur in the bronchi as air moves through tracheal-bronchial passages coated with mucus or respiratory secretions. Rhonchi sounds have a continuous snoring, gurgling, or rattle-like quality. Listen to the following wheezing lung sounds:Ī wheeze may also be lower-pitched, having a snoring or moaning quality in which they are referred to as rhonchi. The classic wheeze refers to the high-pitched whistle-like sound heard during exhalation as air moves through a narrow or obstructed airway. Wheezing sounds may occur during inhalation or exhalation and are continuous with a musical quality. Wheezing is caused by the narrowing of the airways and is associated with asthma, bronchitis, pneumonia, COPD, smoking, heart failure, inhaling a foreign object into the lungs, or an allergic reaction. Types of abnormal breath sounds include wheezing, rhonchi (which sound like low-pitched wheezing), stridor, crackles (also known as rales, and these may be further classified as fine or coarse), and pleural friction rub. The lung sounds are classified according to the sounds involved during inhalation and exhalation phases of the breath cycle, taking note of the pitch and intensity. These are easily identified by auscultation, or listening to the lungs fields with the stethoscope. Hi, and welcome to this video on lung sounds! Lung sounds, or breath sounds, refer to the sounds heard when air moves through the respiratory system. |
