If you already have a GPS system and an MP3 player, you can make do with a regular phone that doesn't offer music or directions. You might not want e-mail on your phone. Getting a smartphone often means having immediate access to work e-mails, social media and the Web. Not everyone wants to be that connected. If you hate feeling like you're missing out on the latest tweets, updates from your friends, and news, then a smartphone will probably seem worth it to you. If your job requires you to be connected all the time, providing immediate responses to e-mails and questions, a smartphone makes sense. You may already have an MP3 player and GPS, but having all those features in one handy device can make life easier and less cluttered. Finally, if your lifestyle has a long commute on public transportation, or if you often have a lot of downtime when you're in public, a smartphone can help you pass the time. It is composed of 300 water Cherenkov detectors (WCD). Each of them is a cylinder of 7.3 m in diameter and 4.5 m in height. POSTSUPERSCRIPT. They are equipped with 4 upward facing photomultiplier tubes (PMT), one 10" Hamamatsu R7081-HQE at the centre of the tank and three 8" R5912 halfway to the edges. 95%. Those two characteristics compensate the smaller instantaneous sensitivity compared to the imaging atmospheric Cherenkov technique, especially at the highest energies for which fluxes tend to be low. Around 10 TeV, the footprint on the ground produced by a gamma-ray shower is comparable to the size of the instrument. Therefore, most of the events triggering the instrument will fall outside the main array which makes the event reconstruction less accurate because of degeneracy between the core position and the energy of the shower. In order to improve the reconstruction of those events thus improving the instrument sensitivity, a sparse outrigger array of small tanks has been added around the main array. First, gravity is a force that causes objects to attract one another. The simplest way to understand gravity is through Isaac Newton's law of universal gravitation. This law states that every particle in the universe attracts every other particle. The more massive an object is, the more strongly it attracts other objects. The closer objects are, the more strongly they attract each other. An enormous object, like the Earth, easily attracts objects that are close to it, like apples hanging from trees. Scientists haven't decided exactly what causes this attraction, but they believe it exists everywhere in the universe. Second, air is a fluid that behaves essentially the same way liquids do. Like liquids, air is made of microscopic particles that move in relation to one another. Air also moves like water does -- in fact, some aerodynamic tests take place underwater instead of in the air. The particles in gasses, like the ones that make up air, are simply farther apart and move faster than the particles in liquids.|Recently released software gives gamers a new tool to create realistic in-game avatar versions of themselves with scanning software. One of the reasons video games are so popular is that they offer people a form of escape. Sure, drawing on an arsenal of weapons to take out the bad guys in "Assassin's Creed" is good fun. But most gamers aren't just gearing up for some real-life battle between groups of trained killers; they're just looking for a little respite from life as an office drone, for instance, or overloaded parent. That yearning to escape may be no more clear than in a gamer's all-important choice of an avatar, the character or image that represents a real person in the video game world or on social media. Many folks go for something that resembles them physically, except maybe with bigger biceps, a smaller waist, more hair or just an all-around stronger sense of badassery. Still, a group of video game techies at the University of Southern California is betting that many gamers would go for an avatar that reflects what's reflected in a mirror.

Acoustic levitation uses sound traveling through a fluid -- usually a gas -- to balance the force of gravity. On Earth, this can cause objects and materials to hover unsupported in the air. In space, it can hold objects steady so they don't move or drift. The process relies on of the properties of sound waves, especially intense sound waves. We'll look at how sound waves become capable of lifting objects in the next section. A basic acoustic levitator has two main parts -- a transducer, which is a vibrating surface that makes sound, and a reflector. Often, the transducer and reflector have concave surfaces to help focus the sound. A sound wave travels away from the transducer. Bounces off the reflector. Three basic properties of this traveling, reflecting wave help it to suspend objects in midair.|Worrying actually can be beneficial. Calling all worrywarts and anxious Annies - you may not have to, well, worry about your worrying habits. Kate Sweeny, psychology professor at the University of California, Riverside, recently published an article in the journal Social and Personality Psychology Compass that suggests worry provides opportunities for people to take control, avoid aversive events and seek desirable ones. There's no debating that excessive worrying can be detrimental, causing depressed moods and even mental illness. According to the World Health Organization, 615 million people had depression and/or anxiety in 2013, which is a 50 percent increase in a span of just slightly more than 20 years - so the negative effects of worrying are nothing to scoff at. Sweeny and her co-author, doctoral candidate Michael D. Dooley, don't discount or advocate for excessive worry. But they did find that when channeled the right way, worry can serve as a motivator, encouraging preventive and productive behavior. Third, sound is a vibration that travels through a medium, like a gas, a liquid or a solid object. A sound's source is an object that moves or changes shape very rapidly. For example, if you strike a bell, the bell vibrates in the air. As one side of the bell moves out, it pushes the air molecules next to it, increasing the pressure in that region of the air. This area of higher pressure is a compression. As the side of the bell moves back in, it pulls the molecules apart, creating a lower-pressure region called a rarefaction. The bell then repeats the process, creating a repeating series of compressions and rarefactions. Each repetition is one wavelength of the sound wave. The sound wave travels as the moving molecules push. Pull the molecules around them. Each molecule moves the one next to it in turn. Without this movement of molecules, the sound could not travel, which is why there is no sound in a vacuum.|Video conferencing can save travel time and increase productivity; thus it has been increasingly changing the business world significantly. Everyone can recognise the symptoms of a bad video conference: choppy connection, fuzzy or echoing audio, poor lighting, distracted attendees. Though it was once touted as the communication method of the future, video calling is often seen as the least efficient way to exchange information. In an office setting, a video conference can be a powerful tool for organising teams and accomplishing goals - but few people understand how to make a video call work well. The most important aspect of video conferencing happens to be stable as well as fast internet connectivity. To ensure the best video conferencing experience, it is essential to understand your video conferencing bandwidth. Bandwidth represents your connection capacity. A low bandwidth will limit and affect the quality of the content seen by the eyes of the user. Go for secure connectivity along with advanced encryption. Password protection in case your only choice is wireless connectivity. Ukraine was part of the Soviet Union; now, it’s a different country. He is concerned that NATO will move in. It might sound paranoid to us, but it’s a security issue for him. Our government recognizes that but, at the same time, we can’t recognize a country that feels that it can control the destiny of another country, even if it’s a neighbor. So the Ukrainians, the U.S. NATO countries can’t accept that the Russians have the sphere of influence in Ukraine, no matter what the Russians do. The Ukrainians and the Ukrainian government are genuinely concerned about Russia undermining Ukraine’s economy and Ukrainian politics. They don’t want to be controlled by another country, and they feel they need some protection. That’s the reason they’re interested in NATO. The U.S. and other NATO countries may not need to have Ukraine in NATO, but if Ukraine wants to be a NATO member, everyone believes it has that right to join in. However, I don’t think this membership will come about very soon, no matter what we say, because that really would be a tipping stone.|Self-supervised video representation learning has been shown to effectively improve downstream tasks such as video retrieval and action recognition. In this paper, we present the Cascade Positive Retrieval (CPR) that successively mines positive examples w.r.t. Specifically, CPR exploits multiple views of a query example in different modalities, where an alternative view may help find another positive example dissimilar in the query view. We explore the effects of possible CPR configurations in ablations including the number of mining stages, the top similar example selection ratio in each stage, and progressive training with an incremental number of the final Top-k selection. The overall mining quality is measured to reflect the recall across training set classes. CPR reaches a median class mining recall of 83.3%, outperforming previous work by 5.5%. Implementation-wise, CPR is complementary to pretext tasks and can be easily applied to previous work. In the evaluation of pretraining on UCF101, CPR consistently improves existing work and even achieves state-of-the-art [email protected] of 56.7% and 24.4% in video retrieval as well as 83.8% and 54.8% in action recognition on UCF101 and HMDB51.

 

 

 

 

Action recognition, the process of identifying actions performed by actors in a video segment, is a challenging and prolific field of computer vision. This challenge is only exacerbated by the constraints of on-the-edge real-time applications. Edge computing is a requirement for many applications that aim for maintaining privacy and scalability. Recent advancements in deep neural networks (DNNs) have lead to a renaissance of the field, driving model accuracy far beyond what was previously possible. This is especially pronounced in skeleton-based action recognition, which instead of using RGB pixel data, relies on human pose information to classify appropriate actions. Currently, near SotA accuracy can be achieved with a simple baseline ST-GCN algorithm, achieving up to 87% accuracy. With accuracy this high being available even to relatively simple models, the realization of complex computer vision applications that rely on understanding the actions of people (e.g. video surveillance, autonomous vehicles, patient monitoring) is now within the realm of possibility. Cathodes made with cobalt won't overheat easily or catch fire, which is a major safety issue, and they'll also be able to store and transfer more energy. Cobalt is not only found in the cathodes of lithium ion batteries, but also in other popular rechargeable batteries like nickel-cadmium and nickel-metal hydride batteries. Since cobalt currently makes up between 10 and 33 percent of rechargeable cathodes, the automobile industry is going to need a lot more cobalt to power the future of electric vehicles. Superalloys are high-performance metals that earn their flashy name from extremely high resistance to wear and heat. Nickel-based superalloys outperform cobalt alloys for stress resistance for temperatures reaching up to 1,706 degrees F (930 degrees C). Beyond that extreme temperature, cobalt-based super alloys really show their stuff. Cobalt has a higher melting point than nickel. Cobalt super alloys are more resistant to heat corrosion. That's why you'll find cobalt superalloys in the stationary fins of gas-turbine engines, which take the brunt of the intense heat generated by jet engines without wearing down and failing.S.|We present a new paradigm named explore-and-match for video grounding, which aims to seamlessly unify two streams of video grounding methods: proposal-based and proposal-free. To achieve this goal, we formulate video grounding as a set prediction problem and design an end-to-end trainable Video Grounding Transformer (VidGTR) that can utilize the architectural strengths of rich contextualization and parallel decoding for set prediction. The overall training is balanced by two key losses that play different roles, namely span localization loss and set guidance loss. These two losses force each proposal to regress the target timespan and identify the target query. Throughout the training, VidGTR first explores the search space to diversify the initial proposals, and then matches the proposals to the corresponding targets to fit them in a fine-grained manner. The explore-and-match scheme successfully combines the strengths of two complementary methods, without encoding prior knowledge into the pipeline. As a result, VidGTR sets new state-of-the-art results on two video grounding benchmarks with double the inference speed. In 2015, a quarry in the Preseli Hills in Pembrokeshire, Wales, was identified as the site where the smaller bluestones of Stonehenge originated. Although the monument's larger sandstone pieces were brought in from around 12 miles (20 kilometers) away, the shorter (yet still massive) bluestones - named for their blueish tint when wet or broken - were somehow wrangled to Stonehenge from Wales, by sea or land, no one knows. Strontium isotope analysis is the technology that allowed the research team to figure out that some adventurous souls were traipsing around the British Isles 5,000 years ago, possibly dragging enormous boulders behind them. Although genetic material is destroyed during the cremation process, the element strontium, which is found in rocks and soil, and which builds up in human bones when humans eat plants, is not. Different strontium isotopes can be found in different geographic locations, so the researchers were able to tell from the cremated bones where the people buried at Stonehenge lived for the last decade of their lives. And 40 percent of the people they analyzed were from the same area as the bluestones. It's possible that the Welsh people interred at Stonehenge never saw it with their own eyes. Lt. Col. William Hawley, the archaeologist who initially excavated the Aubrey holes in the 1920s, mentioned in his notes that some of the cremated remains were found in leather bags, suggesting they were brought there from some other place. Maybe they were part of luggage that included about 60 bluestones. Medieval historian Geoffrey of Monmouth insisted the Stonehenge bluestones were flown there by the magic of the wizard Merlin.
