If you leave them at 7AM and pick them up at 3PM then the question is how many hours is 7AM to 3PM and the answer is eight hours (15-7 8). For example, you would say "Tuesday at 24:00" and "Wednesday at 00:00" to mean exactly the same time. Many digital clocks and printed schedules in Spanish speaking countries use.

Most Spanish speakers do not use AM or PM. We will first study the example of calculating the time duration between 8:13 am and 4:55 pm. Under the 24-hour clock system, the day begins at midnight, 00:00, and the last minute of the day begins at 23:59 and ends at 24:00, which is identical to 00:00 of the following day. The solution is simply a case of adding 12 hours to any pm times ). Numbers under 10 have a zero in front (called a leading zero) e.g. Difference in time the clock indicates5:30 p.m.-11 a.m. Also, the international standard notation of time ( ISO 8601) is based on this format.Ī time in the 24-hour clock is written in the form hours:minutes (for example, 01:23), or hours: minutes: seconds (01:23:45). The clock gains 12 mins in 12 hours, It will gain 1 min in every 1 hour. In some parts of the world, it is called railway time. Use the Right Arrow or Left Arrow to choose between AM and PM.

![]() This is where TextRank automates the process to semantically provide far more accurate results based on the corpus. Keyword extraction can be done by simply using a frequency test, but this would almost always prove to be inaccurate. There are two ways of extracting text using TextRank: keyword and sentence extraction. Summ_words = summarize(wikicontent, word_count = “”) Summ_per = summarize(wikicontent, ratio = “”) Here’s an example code to summarize text from Wikipedia:įrom import summarizeįrom gensim.summarization import keywords Since TextRank is a graph-based ranking algorithm, it helps narrow down the importance of vertices in graphs based on global information drawn from said graphs. Gensim is an open-source topic and vector space modeling toolkit within the Python programming language.įirst, the user needs to utilize the summarization.summarizer from Gensim as it is based on a variation of the TextRank algorithm. Here are five approaches to text summarization using both abstractive and extractive methods. 5 techniques for text summarization in Python However, this does not mean that there is no need for extractive summarization. In a lot of ways, it is a precursor to full-fledged AI writing tools. What makes this method unique is its almost AI-like ability to use a machine’s semantic capability to process text and iron out the kinks using NLP.Īlthough it might not be as simple to use compared to the extractive method, in many situations, abstract summarization is far more useful. It rewrites large amounts of text by creating acceptable representations, which is further processed and summarized by natural language processing. Abstractive text summarizationĪbstractive text summarization generates legible sentences from the entirety of the text provided. Owing to its simplicity in most use cases, extractive text summarization is the most common method used by automatic text summarizers. This, however, also means that the method is limited to predetermined parameters that can make extracted text biased under certain conditions. The method is very straightforward as it extracts texts based on parameters such as the text to be summarized, the most important sentences ( Top K), and the value of each of these sentences to the overall subject. Extractive text summarizationĪs the name suggests, extractive text summarization ‘extracts’ notable information from the large dumps of text provided and groups them into clear and concise summaries. ‘Extractive’ and ‘Abstractive’ are the two methods of performing text summarization. ![]() With this in mind, let’s first look at the two distinctive methods of text summarization, followed by five techniques that can be used in Python. This can get frustrating, especially during research and when collecting valid information for whatever reason. We’ve all come across articles and other long-form texts with a lot of unnecessary content that completely draws us away from the subject matter. Text summarization is a natural language processing (NLP) task that allows users to summarize large amounts of text for quick consumption without losing any important information. ![]() Strava Summit gives you access to more features, such as more in-depth race and performance analysis and the Strava maps feature, which allows you to easily find route suggestions from your current location. There are also handy features like Strava Beacon, which are designed to keep you safe, by allowing your friends or family members to track your live location on a run.Īlongside the free version of the app, Strava has a paid-for membership, named Summit. (Just make sure you opt out of the location tracking features if you happen to be around restricted areas.) Strava supports a variety of running trackers in addition to Wear OS devices and Apple Watch. Strava has all the running tracking features you’d expect - from running speed and distance travelled, to more in-depth performance analytics and weekly miles. That said, if you’re not a competitive runner, don’t let this put you off. The community part of the app allows you to follow your friends, running frenemies, and work colleagues and even set up group challenges, like fastest 5K or longest monthly mileage. We promise it’ll work 99 times out of 100.If you need people around you to keep you motivated, Strava is the app to download right now. Getting out the door is most of the battle, and once you’re running, you’re happy to be there.” Give this a shot. “‘If I get out the door and run for 10 minutes and still feel lousy, I can turn around and run home.’ I don’t think anyone’s ever turned around after running for 10 minutes. “What’s that classic line we tell ourselves when we don’t want to run?” Freedman says. Once again, this gives you something to chase, and it might help encourage you to get out the door (even when you don’t necessarily want to at first). Instead, give yourself a week, a month or even a few months to cover that much elevation gain. This is a pretty monstrous undertaking, but you don’t have to do it all at once. This challenge (which runners can do, too) involves gaining 8,848m of elevation (the height of Mount Everest) in a single workout.

Now they’re like, ‘Hey, I can do this.’ That’s encouraging because the point was to make it accessible to everyone.” Even if you don’t feel like you can run on a given day, you can still go out and do a walk-run style workout. “They’re people who have never been a part of a race. “I’ve also entered a few challenges in team setups, which is fun.” Having a goal is a great way to keep yourself dialled in and eager to train, and if that goal comes in the form of a virtual event, you’ll be able to chase PBs and quick race results all winter long.įreedman says many of the participants in the 416 Challenge are walkers. “ Virtual challenges help me feel that I’m accountable,” she says.

I died so many times but it was worth it to see the next stage. It’s rare for me to find an app that motivates me so much into completing each stage. I found Gravity Guy to be amazingly fun and visually awesome. With 30 levels and 3 different worlds, the variety is strong and the challenge is always a rush. Each time I finally overcame a specific part of the stage, I felt like I earned it. I absolutely love how little I got frustrated. Dying is expected and luckily the checkpoints are very well placed. You have checkpoints that you will probably become very familiar with over time. Stages are actually carefully planned exciting levels rather than the randomly generated ones. The dramatic lighting definitely makes Gravity Guy stand out. I love the one part of the first stage where you enter a room and suddenly the daylight changes to a huge white black light that immediately turns the game from Megaman into Limbo. The entire graphical package works really well. Your character looks like a cross between Sonic the Hedgehog and a South Park character and is highly stylized. Backgrounds are interesting and the textures are really pretty. ![]() Morning, Afternoon, Night, and silhouetted, the game looks simply amazing. Graphically, Gravity Guy takes simple palette swaps to a really interesting level. Add some speed-boosting strips and your heart will be racing like crazy. A guard is chasing you after you break out of prison and if you get caught up on too many obstacles, he’ll catch you. And that’s the point of Gravity Guy: Not die. There are points where you have to let yourself run off the platform and ‘fall’ onto the next one, then immediately toggle the gravity to not die. The game pushes the ante however and increases the speed to insane levels. You can’t jump so any small obstacle has to be avoided through gravity toggles. Tap the screen and your character will turn gravity upside down so you can run on the ceiling. You control the entire game through single taps. Control your gravity by tapping the screen, go as far as you possibly can, and experience the chase!Ĭontrols are standard for games like these. Despite the oddly lethargic title, Gravity Guy is one of the more unique and intense versions of the distance gravity-toggle games that I’ve ever seen. Released by Miniclip SA (makers of Fragger), Gravity Guy is available on the iPhone, iPod Touch, and iPad for $0.99 with a free alternative. This capture continues until the player reaches a position where there are not two or three stones located in the cup. If the preceding cup has two or three stones, then the pieces are captured as well. The stones are removed from the board and placed in the big storehouse located at either end of the board. In the Wari version, if the last seed sown lands in a cup with exactly one or two of your opponent's pieces in it, then the stones become captured prisoners. There are several variations on how to capture, including what is done with the counters that are captured. The hole emptied is left empty throughout the rest of the game.Ĭapturing A player may capture a seed from the board on the last lap. In Wari, if a hole contains 12 or more seeds, the sowing will lap around the board more than once. ![]() The lap will end when the last seed sown ends when the seed sown ends up next to a empty hole. Instead of scooping up the contents of the last hole, however, the player uses the contents of the next hole to continue with the lap. The Indian style laps, which are called pussa-kanawa, are essentially multiple lap games. The players turn ends when the last seed falls into an empty hole. In a multiple lap game, if the cup in which the last seed is placed contains seeds, then the contents of the cup are picked up and redistributed. Sowing If the turn ends after dropping the last seed into a bin, then the game is considered to be a single lap game. The second player does the same except he goes in an anti-clockwise motion. In some versions of the games, the seeds in which the player can select from is limited to their side of the board. On each turn a player selects one of the bins on their side and takes out all of the pieces (stones) in it, and moving along counterclockwise, drops one piece in each bin they cross. Four counters or seeds are distributed into 1 of the 12 small holes. In Wari, the board has two rows of six holes. The board starts out with a given number of pieces in each of the smaller bins. Players place the board lengthwise between them. To win: To end with more pieces in your base than your opponent. He drops one stone into the bowl to the right of his bowl and continues up the board counterclockwise placing stones into the right bowl. To move: The first player starts by scooping up his stones from one of his small bowls. Stones, seeds, shells or any similar object that is easy to handle and distribute into the cups. In some places in Africa holes are made in the ground and seeds or shells are used as counters. ![]() One does not need a physical board, however to play the game. In general, the board is made up of smaller bins which are located next to each other along the length of the board (each of the two rows belongs to one of the players) and at each end of the board there is a larger bin which represents the base or store for each opponent. The Boardĭepending on the variation, the board can have different amount of holes. Although there are at least two hundred different regional variations, West African Wari is perhaps the best known. Much of the original rules have remained unchanged and even today Mancala is popular across most of Africa, the Middle East and Asia. ![]() It has long been played in Africa for thousands of years. Historians believe Mancala may be the oldest game in the world. The counters which are also known as seeds are redistributed with the goal of taking prisoners. The Mancala family of games share the basic gameplay of sowing counters into holes or cups. Mancala does not refer to any specific game, but instead is the name for a large family of board games played around the world. ![]() #BATTLETECH RECORD SHEETS SUCCESSION WARS RECORDS UPGRADE# These products were created by scanning an original printed edition.

Sea stars will be found in both very shallow water or deep water, but mostly in the shallow water on the ocean floor or on coral reefs. Sea Stars always live in the ocean, but they can be found out of the water attached to rocks during low tide. The Crown-of-Thorns has been known to leave many places of coral destroyed. They will feed mostly on coral and destroying it. This sea star has tiny spines all over each of its arms that are poisonous. This way it will not become over populated or crowed.īut some Sea Stars can harm its habitat, like the Crown-of-Thorns starfish. Since they are carnivorous they prey on bivalve controlling how many organisms are in the ocean. Sea Stars are very important to its habitat. In feeding it will grab onto the shell of the bivalve and prey it open, once it gets it open far enough it will stick it's stomach into the creature and pours out enzymes which partially digest the animal in it's own shell. The tube feet on Sea Stars are very important they help in both locomotion and feeding. This makes it so that it can see and react to movement.Įach Sea Star has its own unique coloring which they use as a camouflage or a warning to both prey or predators. On each arm there is also an eye stop that is located at the very end of each arm, but this eye can only see light and dark. On the radial canal there are tiny teeth called ampullae. The radial canal stretches across the length of each arm. On each arm there is both a radial canal and an eye spot. This shows that the species of Sea Stars variety in shape, size, and color. Some Sea Stars have the spiny surface for a means of protection and others are smooth and do not have any. The opening to the water vascular system is on the ventral surface and is called the madreporite, it filters the water going into the water vascular system. The topside of the sea star, with the spines on it, is called the dorsal side. The mouth is located underneath the sea star, which is called the ventral surface. Some species of Star Fish have more or fewer arms than the basic five arms. Each of the spines is surrounded by skin gills which function in respiration, along with the pedicellariae. Sea Stars are covered with prickly structures that are sticking out from the skeletal plates. The Sea Star is held together and protected by its exoskeleton and that is where it gets its hard body. Sea Stars have radial symmetry because of their five arms. If it contains the central part of the body it has the ability to regrow a whole new Sea Star. If one of their arms were to get ripped off, they have the ability to reproduce a new arm. They can also repair themselves if they get injured. Sea Stars are carnivorous that mostly prey on bivalves that they come across from very slowly moving across the ocean floor or a reef. Tube Feet of a Sea Star, this is how sea stars move and get around slowly. The waste is than held in the rectal saecae, for only a short time, and then is excreted through the anus. The food will go into the mouth, than go through a small tract called the esophagus than into the two stomach were food is broken down by the stomach enzymes. The digestive system consists of a mouth, esophagus, cardiac stomach, pyloric stomachs, rectal saecae, and anus. The Sea Star has no intestine instead the food is digested in the stomach by enzymes produced in by the digestive glands. Than the foot's muscular fibers shorten the foot again and forces the fluid back into the ampulla. When the tube foot comes in contact with the surface below it, it suctions to the surface of the object by creating a vacuum. The tube foot is forced to become longer because the ampulla reduces in size forcing the fluid into the tube foot. (Tube Feet all end with a suction cup-like feature on the bottom). Each of the Lateral Canals contains a valve, which then goes into a bulb called an ampulla or a tube foot. On either side of the Radial Canal is a short Lateral Canal. The Circular Ring Canal is connected to the Radial Canal which extends into each of the five arms of the Sea Star. The Water Vascular System is filled with seawater and is mixed with protein, potassium and amoeboid cells. ![]() Sea Stars rely on their Water Vascular System for movement (Tube Feet), respiration (ampullae), and circulation. |
