Cubo de rubik colores2/29/2024 If you’re practicing and you want to scramble a solved cube, you have to keep the cube intact and scramble it up manually. This is a trap that has caught many novice cubers. Now, is it always possible to solve this jumbled cube, without breaking it apart? You get what looks like a normal scrambled cube, and so far we’ve counted every way you could do this, (3 88!)(2 1212!). Suppose you break open a Rubik’s Cube, remove each cubie, and then put all the cubies back in random slots (with corner cubies only fitting in the corners, and edge cubies only in the edges). Here’s a thought experiment (which perhaps you’ve done for real!) to illustrate: It relates to a fact about Rubik’s Cube that is often felt, but not always understood. What’s left of the formula (3 88!)(2 1212!)/12 is that division by 12. Then there are 12 locations, so 12! is the number of ways they can go to those spots. Edges only have two orientations, so the 12 of them have a total of 2 12 mixes of orientations. The next chunk, (2 1212!), is the same idea, now for the edges. The 3 8 is their orientations, while the 8! is their locations. Thus the first chunk, (3 88!), counts every way the corner cubies can fit into the cube. That yields the calculation 8*7*6*5*4*3*2*1, which is 8!, or “eight factorial.” The second corner cubie is left with seven options, the next left with six, and so on, down to the last corner cubie, which must go in the last corner slot. There are eight corner slots, so the first corner cubie has eight options. Giant Jagged Rubik's Cube Is a Beautiful Nightmare.This Robot Can Solve a Rubik's Cube with One Hand.

Tomb raider cast 2001 rotten tomatoes2/29/2024 The Pumpkin Eater Photos Richard Johnson THE HAUNTING, Richard Johnson, 1963 JULIUS CAESAR, R. Johnson's final film was the dark comedy "Radiator" (2015). He married Lynne Gurney in 2004, and continued acting in new projects like the Woody Allen comedy "Scoop" (2006) and the holocaust drama "The Boy in the Striped Pajamas" (2008). The new millennium found Johnson playing the head of the Illuminati in the action blockbuster "Lara Croft: Tomb Raider" (2001). He starred in acclaimed mini-series like "The Chamomile Lawn" (Channel Four, 1992) and "Anglo-Saxon Attitudes" (ITV, 1992). Johnson's marriage to Norlund ended in 1989, but his acting career remained prolific. In 1982, he married Scandinavian beauty Marie-Louise Norlund, with whom he would have a daughter. He would serve as CEO of the company for the following ten years, producing films like "Turtle Diary" (1985). In 1981, the enterprising performer decided to form his own production company, founding British United Artists. Johnson also served as a council member for the British Academy of Film and Television Arts during this period. The '70s found Johnson appearing in films like the Italian film "Zombi 2" (1979) and the thriller "Hennessy" (1975), for which he wrote the original story. A romance bloomed between Johnson and his co-star, and the two were married that same year, though they divorced a year later. A particularly memorable on-set experience came along for the actor in 1965, when he appeared in the historical comedy "The Amorous Adventures of Moll Flanders" (1965) with Kim Novak. By Johnson's own account, he was even offered the role of James Bond in the film "Dr. Johnson remained a popular actor during this period, however, starring in films like the horror classic "The Haunting" (1963). The studio even wrote a part for him into the biblical epic "King of Kings" (1961), though the role was eventually cut from the final film. His performance persuaded the executives at MGM to grant him a contract. Johnson was cast in his first credited film role, playing Captain Danny De Mortimer in "Never So Few" (1959). Though the union lasted only five years, the couple produced a son and a daughter. In 1957, he married actress Sheila Sweet. Johnson began his career as an actor on the stage, starring in a number of productions with London's Shakespeare Memorial Theatre throughout the '50s and '60s, including "Romeo and Juliet," "As You Like It," and "Julius Caesar." When the troupe was renamed the Royal Shakespeare Company under the direction of Peter Hall, Johnson was named as an Associate Artist of the company. When he completed his service in 1948, he attended the Royal Academy of Dramatic Art. The next year, however, World War II compelled the young actor to join the Royal Navy in service of his country. He eventually made his professional debut at the age of 17, appearing in a production of "Hamlet" with John Gielgud's repertory theater in 1944. Born in Essex in 1927, Johnson attended Felsted School. Famous for his rakish charm and easygoing manner, British actor Richard Johnson had a career that spanned seven decades. After returning from their honeymoon and showing home movies to their friends, Shrek and Fiona learn that her parents have heard that she has married her true love and wish to invite him to their. Atomic clock online2/29/2024 Precise time measurements are also essential for accurate navigation and the support of communications on Earth and in space. Mobile phone base stations must have stable and accurate oscillators in order to handle the massive amount of data being transmitted and received. Radio and television stations require both precise time-of-day and frequency in order to broadcast programs. Power companies use precise time to regulate power system grids and reduce power losses. Synchronization between two or more locations is necessary for high-speed communication systems, banking and stock transactions and transmitting everything from e-mail to sonar signals in a submarine. Precise time and frequency synchronization have many uses in everyday life. Other physical quantities, like the volt and meter, also rely on the definition of the second as part of their own definitions. This definition makes the cesium oscillator (sometimes referred to generically as an atomic clock) the primary standard for time and frequency measurements. Since 1967, the International System of Units (SI) has defined the second as the period equal to 9,192,631,770 cycles of the radiation, which corresponds to the transition between two energy levels of the ground state of the Cesium-133 atom. The best cesium oscillators (such as NIST-F1) can produce frequency with an uncertainty of about 3 x 10 -16, which translates to a time error of about 0.03 nanoseconds per day, or about one second in 100 million years. If an atomic clock was off by 1 Hz and the frequency was 1 GHz (1 billion Hz), then it would be off by one second in 31.7 years or, roughly, 86 microseconds (0.000086 s) per day. The benefits of an atomic clock are that the resonant frequencies are natural properties (not human-made) and that they are very high frequencies, in the billions of Hertz. In this case, the generated frequency is the 'tick'. If the correct frequency can be generated to make the atoms change, then that frequency can be counted or divided down and compared. With an atomic clock, there is a natural tendency of atoms to change energy levels when they are exposed to very specific ("resonant") frequencies. If the quartz frequency on a watch is 0.1 Hz off, the watch will be off by one second in 327,680 seconds or, roughly, 0.26 seconds per day. For instance, if a half-swing of a pendulum is actually 0.1 Hz off, then the grandfather clock will be off by one second in ten seconds. By dividing a high frequency down to a low frequency, the accuracy can be increased. The ticks are used to advance the seconds on the clock. The frequency is "counted" by dividing it by 32,768 to equal one second 'ticks'. With a quartz clock (like most wristwatches), a piece of quartz crystal is cut and used in an electronic circuit where it vibrates at a certain frequency (usually 32,768 Hz). One cycle per second equals 1 Hertz (Hz). The arm of the pendulum is adjusted in order to make each half-swing take one second. For example, the pendulum in a grandfather clock swings back and forth at the same rate, over and over, and the gears "count" the swings. What are some sources for further reading about clocks and timekeeping?Ĭlocks work by counting a periodic event with a known frequency. What are Julian Date and Modified Julian Date (MJD)? What is the origin of hours, minutes and seconds? How are stopwatches and timers calibrated? Why must time and frequency be measured so precisely? Stopwatch calibrations, calendars and history. Cesium clocks, why we need precise time and frequency.

Photography black models2/29/2024 It is not appropriate to discuss intimate details of anyone’s relationship or spread gossip. Getting too personal, no! Don’t pry for personal information just to be nosy. Aim to get something original, that you can feel proud is created by you. Instead, ask to do something along those lines and put your own twist on it. If you do it again, is that not plagiarism? Don’t ask the model to recreate it. That shot has already been done by the same model with another photographer. There are some great shots in the model’s portfolio, which is why you chose to work with them, right? Although these photos inspire you, and you want some in your own portfolio, refrain from copying them. If the shoot is likely to require a lot of attention to styling, then you should consider bringing an assistant, stylist, or makeup artist to help you. Inappropriate touching is completely unacceptable. If they need assistance with anything, they will ask. Instead, tell the model that something needs adjusting and let them make the changes themselves. Under no circumstances is it okay to touch the model unexpectedly. Do not approach the model to adjust it yourself. You’ve just noticed that your model has a hair out of place, twisted straps or crooked jewellery. Working with models: key things not to do Don’t touch It’s a team effort to achieve great images enjoy the process as well as the results. Laugh, chat, smile, be spontaneous, bounce ideas, get creative and have fun with the shoot. With both of you looking at the images, you can make any necessary adjustments. It’s a chance for them to see how they look, what is working well, and what to improve. It’s great to show the images on the back of the camera to the model to see how things are going. So, remember, if you’ve got the shot, move on. Not to mention that the amount of time you’ve now spent shooting this style means that you’ll end up rushing to do the set you saved until last. But stop! How many do you need? If you spend any longer on these shots, you’re only going to make it harder to choose later. The scene is set, props are in place, the model is styled and steadily changing pose after each press of the shutter, so you’re clicking away non-stop, it’s all working beautifully. Going through the mood board together will allow both of you to work out where, when, and how to shoot a particular shot and in which order. Be prepared to listen to the model’s contribution as they might suggest something to add to your ideas or have just the right garment or prop to suit the image. Discussing what you’d like to achieve throughout the shoot will help the model to prepare and may even throw up a schedule that you hadn’t considered. This will help to create a plan of action. If you’re shooting for a few hours, agree when a break will be scheduled and be flexible. If the model must hold a particularly strenuous pose, let them know the moment they can relax in between shots. The same consideration should be given when shooting in direct sunlight, which might cause squinting or sunburn. Try to be timely and if you do have some adjustments to make, use that opportunity to suggest to your model to put their coat on for a moment until the shot is set up and ready to go. Although they might not mind because they’re as keen to get the shot as you are, shivering with cold is not a good look. You may well dress appropriately to suit the temperature, but your model might not. If you’re planning a shoot outside on location, or even in a derelict building, please consider the weather conditions. It’s encouraging and keeps the engagement between you and the model flowing. Simple phrases like ‘great’, ‘super’, ‘that’s good’, and ‘hold that’ is essentially the feedback that lets the model know that they are working well. It’s important to give little hints that things are going okay. While the model is posing, it’s easy to get caught up in your own world of repeatedly pressing the shutter, holding your breath, and forgetting to talk. This will help you to build a rapport and it sets a good tone for the rest of the shoot. It helps to put each other at ease, relax, and be open to sharing ideas and discussing the shoot. Good communication between a model and a photographer is imperative for a great photo shoot. Working with models: key things to do Communicate Here are some pointers on what to do and what not to do. As a guideline, treat those you photograph as you would any work colleague, with good manners, respect, consideration, and professionalism. There are unspoken rules and some which might seem obvious but unfortunately are missed. Pink tissue fragments in urine2/29/2024 Yes, you can continue your normal activities with a stent in place.

Urinary retention, meaning you are unable to urinate at all.Thick clots or tissue in the urine that is causing any difficulty urinating. Constant dark bloody urine that does not ease up with increased fluid intake.Some symptoms are not normal with a stent in place, and you should see your doctor. A cramping-like sensation in the mid to low abdomen, often described as feeling like a muscle cramp Frequency will increase when increasing fluid intake. Frequency can range from every few minutes, to once an hour. Frequency – going to the restroom more often than normal.Urgency – the feeling/sensation you get when you have to go.Dysuria can usually be relieved by increasing fluid intake and avoidance of certain drinks, food, and some medications. Dysuria (burning with urination) – this can be mild to moderate.Blood in urine – Can range from light pink tinged urine, to a darker color similar to red wine.Normal symptoms you may experience when a stent is in place include: Inflamed, swollen, or damaged ureteral tubes in need of healing may have a stent placed to keep the kidney draining during the healing process. Other reasons include stricture (abnormal narrowing of the ureter), and outside forces such as a tumor pushing on the ureter and causing a blockage. Kidney stones are the most common reason for placing a ureteral stent. It may also be placed to prevent blockage. Why are ureteral stents placed?Ī ureteral stent is placed to allow urine to flow from the kidney to the bladder when the normal flow is blocked. Stents may have a string on the end that is visible outside the body. When placed in the ureter, the top portion of the stent has a small curl that sits in the kidney and the opposite ends curls in the bladder. It’s flexible and approximately 10 inches in length. What is a stent?Ī stent is a small hollow tube that is placed into the ureter. Some people are born with two ureters to one kidney or two ureters to both kidneys. Typically there is one ureter for each kidney. Ureters run vertically (up and down) in the mid-part of the abdomen. What is a ureter?Ī ureter is the tube-like structure that transports the urine from the kidney to the urinary bladder. Below are the answers to some of the questions we receive about ureteral stents. The most common reason for ureteral stents is the treatment of kidney stones. Ureteral stents are small tubes inserted into the ureter to treat or prevent a blockage that prevents the flow of urine from the kidney to the bladder.

Mediacoder 32 bit download2/29/2024 The negative effect of patent licensing on free and open-source software has also been cited as a reason for the creation of AV1. According to Microsoft's Ian LeGrow, an open-source, royalty-free technology was seen as the easiest way to eliminate this uncertainty around licensing. In addition, various patent holders were refusing to license patents via either pool, increasing uncertainty about HEVC's licensing. Unlike previous MPEG standards where the technology in the standard could be licensed from a single entity, MPEG LA, when the HEVC standard was finished, two patent pools had been formed with a third pool on the horizon. In addition to the increased cost, the complexity of the licensing process increased with HEVC. Only 42 days before, on 21 July 2015, HEVC Advance's initial licensing offer was announced to be an increase over the royalty fees of its predecessor, AVC. The official announcement of AV1 came with the press release on the formation of the Alliance for Open Media on 1 September 2015. Additionally, the Alliance's seven founding members – Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix – announced that the initial focus of the video format would be delivery of high-quality web video. The Alliance's motivations for creating AV1 included the high cost and uncertainty involved with the patent licensing of HEVC, the MPEG-designed codec expected to succeed AVC. ĪVIF is an image file format that uses AV1 compression algorithms. Like VP9, but unlike H.264 (AVC) and H.265 (HEVC), AV1 has a royalty-free licensing model that does not hinder adoption in open-source projects. In 2018, Facebook conducted testing that approximated real-world conditions, and the AV1 reference encoder achieved 34%, 46.2% and 50.3% higher data compression than libvpx-vp9, x264 High profile, and x264 Main profile respectively. The AV1 bitstream specification includes a reference video codec. It was developed as a successor to VP9 by the Alliance for Open Media (AOMedia), a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors. There's no video editor, and very little control over the converted file, but Icecream Media Converter is an easy-to-use audio/ video conversion tool which handles the basics well.AOMedia Video 1 ( AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet. There's also a History option where you can view all your recently converted files, good news if you've forgotten where they were saved. Open the program and the last file converted is named, with a link to its folder. Previous conversions are also handled well. It's kicked off with a click you're able to pause or cancel the conversion of one or all your files the program runs its conversions very quickly, and opens the destination folder immediately afterwards for you to browse the results. The conversion process is better designed. There are no options to set resolution, codec, bitrates or anything else: just a single "Quality" setting with four options (Best, Good, Average, Bad). What you don't get here is any real control of the converted file.
