Architect AD9Architects said that the first approach of the architect at this project was a handmade card shop. The remaining functional blocks are organized based on the balance factor. The house faces the West, so the buffer spaces are formed as an essential reason to minimize noise, dust and heat. The gaps found are the transparency where fresh air, trees, and light bring together many of the elements needed for a tube house in the central climate. Da Nang house is located in Vip island area, Hoa Xuan ward, Cam Le district, Da Nang city, completed in 2020. The house has an area of ​​​​500 m², the facade of the building stands out with the color of baked bricks arranged in blocks. The round squares in the front are planted with trees, as a highlight for the house in the middle of the urban area. The materials used are mostly bought locally such as fired bricks, natural split stone, washed stone… The interior is used from the family’s previous house. The architect shared: “The completion of a housing project during the COVID-19 epidemic period is something the office feels very precious, thank you to the construction teams and families for always accompanying us. .” The architect designed many buffer spaces to minimize noise, dust and heat. From the ground floor to the upper floors, all floors are connected to each other, this is to overcome the West facing house. Besides, trees, light and buffer space are essential elements for a tube house in the Central region. Public and private spaces are connected by atrium. The connection between members becomes easier. Fully equipped kitchen and dining room. A corner of planting trees in the front of the house to the west. The materials used in the house are mainly local materials such as fired bricks.

On the evening of June 10, Archer company from California, USA, unveiled its new electric vertical take-off and landing (eVTOL) prototype at an event held in the city. Los Angeles. The innovative vehicle is called the electric Archer Maker, and to demonstrate what it can do, event participants were invited to participate in a flight simulator. As the problem of congestion becomes more and more difficult to solve, more and more companies are launching products and ideas that are created to take people to the sky and bypass the heavy traffic roads below. That is also what the Archer flying taxi is trying to achieve. The company’s new aircraft, the Maker, is a two-passenger eVTOL vehicle designed to serve as a test machine for new technologies. It has a distributed electric propulsion system that allows 12 electric motors to draw power from 6 individual battery packs. This design makes it possible for the Maker to maintain flight even if one or two of its motors fail. One of the main focus of the company is the noise generated by the propellers. No one wants a city filled with eVTOL vehicles hovering in the air and making louder noises than the cars below. To overcome that problem, Archer specially equips Maker with 12 sets of small propellers, which can rotate more slowly than conventional helicopter propellers. The new Archer Maker 2022 will be able to soar to about 610 meters above the ground, and according to the company, it will be 100 times quieter than a helicopter. In other words, Maker only makes as much noise as a home refrigerator. In terms of speed, the Maker will be able to reach a maximum speed of 240 km / h, and will use only 30% of the battery capacity for trips of 32-64 km. This will allow the battery to quickly charge before the next flight. The plane will be ready to take off after about 10 minutes of charging and has the potential to make 40 flights per day. In addition, it is also worth noting that the Maker has a very light weight of only about 1.5 tons, 300 kg lighter than a Tesla Model 3. Archer is expected to complete the first test flights of Maker. in the fourth quarter of 2021, and plans to start production in 2022. In an effort to reduce its carbon footprint, United Airlines has announced plans to purchase $1 billion worth of eVTOLs, and if all goes as planned, they are expected to begin flights trade from Los Angeles and Miami by 2024. The California-based company also plans to build a complete network of take-off and landing points for the eVTOLs. However, they won’t really create new spots because there really isn’t much extra space in megacities. Instead, Archer will use the roofs of the parking garages.

Samsung launched the world’s smallest camera sensor (Image: The Verge) Recently, Samsung has launched a new camera sensor for smartphones, with the smallest pixel size in the world. ISOCELL JN1 is a 50MP sensor, 1/2.76 inch size is relatively small, pixel size is only 0.64 μm. Camera experts often say that the smaller the pixel size, the worse the image quality and the higher the noise. So why does Samsung continuously release sensors with such small pixel sizes? According to Samsung, the small camera sensor can still ensure the resolution of the photo. The smaller sensor size makes it easier to design telephoto and ultra-wide-angle camera modules, as the lens structures of these cameras are more complex than conventional cameras. That means the camera will be less convex. Like many cameras the sensor can capture images at 12.5MP resolution, which equates to a pixel size of 1.28 μm. Samsung also integrates ISOCELL 2.0 technology, which increases light sensitivity by 16%. Samsung says the JN1 is currently in mass production, so it is likely to appear on Samsung smartphones in the near future.

The Golden Gate Bridge in San Francisco has been making strange noises for the past year. Photo: Reuters Strange sound According to The Guardian (UK), in a windy tunnel in the southwest of Ontario, California, a team of acoustic and aerodynamic experts is testing on a model of the railing of the Golden Gate Bridge. Experts have contracted to solve the mystery of a strange humming sound emanating from the famous bridge in San Francisco over the past year. Some residents living nearby feel extremely uncomfortable hearing this noise. Accordingly, this mysterious sound appears only on days with strong winds. It has been compared by some to the “ghost harmonica”, “the sound of the monks chanting”, or the “wheezing sound”. This strange sound quickly became a thrilling story in San Francisco. A music producer has put it on a track of existential fear. Some amused people consider it the “mellow song” of the bridge, others say the sound is very “creepy” and they can’t stand it. aliens made this noise. “It sounds like a noise I can imagine prison guards use to torture prisoners,” one social media user shared. But whether San Francisco people love it or hate it, engineers will get rid of it next summer. Video: The mysterious sound from the Golden Gate Bridge (Source: Youtube): The cause of the mysterious sound After residents of the city began complaining about the noise in June 2020, authorities began an investigation. They monitor this sound and use instruments to measure the vibration of the humming. They found that the sound usually comes out at 440 hz, matching the note of A. The noise occurs when the wind hits the new balustrade, installed from a slight angle, slightly north or south, relative to the normal wind from the west. “After carefully studying the phenomenon, we determined the sound was coming from the new aerodynamic railing that we installed on the west side,” said Paolo Cosulich-Schwartz, a spokesman for the Bridge Management Board. . “It is part of the Golden Gate Bridge upgrade, designed to protect the bridge by allowing it to withstand sustained high winds of up to about 160 km/h.” He said new, thinner railings have been installed to ensure the bridge doesn’t have the same problems as the ill-fated Tacoma Narrows Bridge in Washington. The bridge shook violently in the wind, then collapsed in 1940, shortly after a few months of construction. “So we had to go ahead with this project. As climate change leads to more extreme weather events, it is imperative that the construction be completed as soon as possible,” said Cosulich-Schwartz, adding that the building was retrofitted with wind resistance in 2016. last year at a cost of $12 million. A study conducted in 2013 showed that the maximum wind speed that the bridge can withstand is 111 km/h. Since its inauguration, the Golden Gate Bridge has been closed 3 times due to bad weather conditions, in 1951 with strong winds of 111 km/h, in 1982 with strong winds of 113 km/h and in 1983 with strong winds of 121 km /H. Fortunately, no damage occurred. So bridge engineers looked for newer thin slats that would allow the bridge to withstand winds of up to 160km/h. They just didn’t expect the bars to create such a “symphony”. Wind gusts of 160km/h are only possible in the event of a tornado, hurricane or tropical storm, said Warren Blier, a senior science official with the National Weather Service. The Golden Gate Bridge has been closed 3 times in its history due to strong winds. Photo: AP Attempts to silence the noise Meanwhile, engineers are determined to find a way to fix the problem. At engineering firm RWDI, an hour west of Toronto, a model of a bridge the size of a conference room was built in a wind tunnel. Engineers are testing various wind speeds and modifications to see if they can quell the noise. However, in the city of San Francisco, not everyone wants this noise to go away. A local blogger even created a sound list around the Golden Gate Bridge to help listeners sleep better. “I love the sound,” says Brianne Howell, a resident of west San Francisco, who shot a video of the bridge humming on one of her regular walks along the coast. “It reminds me of the weird sound in a horror movie. It’s sad to have to remove it.” Construction of the Golden Gate Bridge was started in 1933 and completed in 1937. The bridge spanning the Pacific Ocean, connecting the city of San Francisco with Marin County, has a length of up to 2,700 meters and a ground height of nearly 90 meters. . The Golden Gate Bridge is not only famous for its arduous construction process, but is also known as a tourist magnet of the United States.

However, at that time, Hendrix did not think about the expensive living in New York, ranked 3rd in the 10 cities with the highest spending and housing prices in the world, according to research by consulting firm ECA International . While many friends move to more remote boroughs like Brooklyn or Queens to save money, Hendrix insists on living alone in midtown Manhattan. However, with a small amount of money provided by her parents, this 21-year-old girl can only live in a micro apartment. In New York, micro houses are only about 4.5-9 m2 wide and are usually suitable for single people. Hendrix found a 7 square meter apartment in the West Village for $1,345 a month. “The building is in the heart of the city, has fire exits and is the perfect space for a recent college graduate like me.” Liv Hendrix’s 7 square meter room. Micro-houses appeared in the US since 1987. However, after the Covid-19 pandemic broke out, these few m2 apartments became a trend. The majority of tenants are low-income groups or young single people. In New York, since 2015, the city government has been testing the My Micro NY micro-apartment model at 27th Street, Brooklyn Navy Yard in the Manhattan district. 22 out of 55 micro apartments are for low-income people. The remaining apartments are subject to commercial rents of over 3,000 USD/month. Make the most of every space In the small room, Hendrix’s bed took up most of the space. So during the day, she often doubles the bed, stacking extra mattresses and pillows around to turn it into a couch. This way helps Hendrix have more living and working space and correct the habit of sleeping in every morning. She had thought about using the attic as a place to sleep. “However, this option is not feasible because I am afraid that the attic will not support the weight or I may roll down at any time.” The kitchen area right next to the bed is where Hendrix does everything from brushing his teeth and washing his face to cooking, making coffee and washing dishes. “Although it’s a bit inconvenient, I still can’t get rid of the habit of drinking coffee every morning. I have to stand on top of the refrigerator to get coffee, water heater and make drinks right under the sink because there is no space at the counter.” . Without a closet, Liv Hendrix hangs clothes on a drying rack, hangs bags and shoes on the wall. After breakfast, Hendrix also cooked food for the day and cleaned the sink to use for other things. The 7 m2 room has no room for a wardrobe. Hendrix had to buy 2 drying racks to hang clothes for work. And her pajamas, underwear, accessories… were stored in a big box by her. All shoes and bags are hung on the wall by Hendrix. “Doing that gives both room and decoration.” The toilet and bathroom areas are also extremely cramped. Hendrix said she couldn’t put on makeup in the bathroom because there wasn’t enough light and storage. “One thing that annoys me is that the bathroom floor is always wet. I use the shower to shower in the morning but by the afternoon the floor is still not dry.” Do not receive guests at home Hendrix estimates his apartment can accommodate up to three guests, but with the condition, they can only sit still on the bed. Because of this inconvenience, she hardly ever invites guests to her house. “I have two friends who live downstairs, but we mostly meet in their more spacious room. If it feels too crowded, we can go down the street or to the park near our house.” Hendrix says the apartment’s central location is both a plus and a downside. The most obvious benefit is ease of movement. The Hendrix residence is full of everything from convenience stores, restaurants to parks, cinemas, and entertainment areas. View of New York City from Liv Hendrix’s apartment. “When the weather is nice, I like to sit for hours at Washington Square park. It’s so close to my apartment that it feels like a backyard. I also love living near the famous restaurants.” However, noise is one of the biggest minus points of the apartment. The space is not soundproof, making the noises from the traffic and the street seem to be amplified at night. “I have to play loud music to drown out the noise, but on terrible nights I have to use earplugs.” Hendrix says that micro apartments are definitely not the perfect choice. One day, she will also dream of houses with large living rooms, full refrigerators, wardrobes… However, small spaces also have their own advantages. “I have learned to keep only the items that are really necessary, limit shopping. In addition, I also find decoration very important because it can turn the apartment into my real home. “.

Tulip turbines are “planted” in urban areas, on the rooftops of houses in Amsterdam, the Netherlands Traditional wind turbines are often located in the sea, are huge in size, make loud noises, can harm birds, and it is important that very strong winds are needed to generate electricity. The new tulip-shaped design overcomes all of the above shortcomings, it only needs a normal wind to generate enough electricity for a family to use comfortably all day. Israeli-American Dr Daniel Farb, the inventor of the tulip turbine, said the unique aerodynamic design makes the turbines quiet, efficient and capable of generating more than 50% of the electricity in clusters. Shaped like glossy flowers in a variety of colors and sizes (1m, 3m and 6m high), the tulip turbines are designed to double duty as electricity generation and artistic decoration on the rooftops. home, shopping mall, school… In addition, a solar system combined with tulip turbines could reduce overcrowding during the late afternoon peaks in many parts of the world when sunlight goes out and strong winds pick up.

Customize sharpness parameters on smart TVs. Photo: Lifewire However, the reality is not so, on most smart TVs today, the Sharpness feature only has the effect of “edge enhancement” (simply speaking, expanding the border), and this can reduce some small details on the picture. That’s why you should reduce the Sharpness parameter to less than 20% or less (possibly 0). On the left is the original image, and on the right is the Sharpness enhanced image. It’s not hard to notice that the image on the right has some extra halos around the subjects, which is what the Sharpness feature brings. Normal image and Sharpness boosted image. Photo: CNET This basically makes objects easier to see, but they also make other areas grainy. In fact, the image that has not been sharpened will be softer, helping you to see small textures on the walls, facial pores, etc. Note, if you are using a 4K TV, users will not be able to receive it. See the difference when increasing and decreasing the Sharpness parameter. In short, to get the best visual experience when watching TV, the easiest way is to switch to Movie mode, or you can tweak the Sharpness parameter to 0-20%.

Speakers participating in the Russia-Vietnam Forum on Artificial Intelligence (AI) (photo source VOV.vn) “The information on the market today seems a lot, but the raw data is often very noisy with missing information. Too little data in unpopular areas and there are too many types of real estate” – said Mr. Tran Hoang Tung, representative of Meey Land (Meey Land Group Joint Stock Company). According to Mr. Tung, this leads to difficulties for both the seller and the buyer in finding a suitable real estate, thereby prolonging the real estate transaction time, especially for those who perform real estate transactions. transaction for the first time. “There is not enough information to give an appropriate selling price for the seller, or to have a reasonable financial plan for the buyer,” a representative of Meey Land shared. Currently, the selected solutions are: Find real estate experts, brokers, and search for information on the internet. However, these methods require a lot of time, skill and are difficult to verify information. According to the representative of Meey Land, these problems can be solved by applying Artificial Intelligence (AI) to the research and analysis of market data. “By analyzing data, we can solve two things. Firstly, find out the important factors affecting real estate prices: area of ​​use, value, location, contractor/investor, number of bedrooms… Second, group of properties properties with similar factors to determine the price range of real estate in a short time without human intervention “- Mr. Tung shared. Mr. Tran Hoang Tung – Director of AI Project is presenting on “Application of AI in real estate valuation” The application of Artificial Intelligence (AI) in the valuation of real estate assets is part of an overall problem of 26 products/utilities launched by Meey Land with the ambition of solving problems in the real estate market. real estate by applying technology in activities and transactions. “The systematization of data by Meey Land’s AI will help make the real estate market more transparent, shorten transaction times and increase liquidity,” said a representative of Meey Land. In addition to the sharing of the Vietnamese representative, Meey Land, the 1st Russia – Vietnam Forum on Artificial Intelligence (AI), there were many other important contents that attracted the attention of attendees. Events like this forum promise to strengthen cooperation between businesses and organizations of Vietnam and the Russian Federation in the field of information technology in general and artificial intelligence (AI) in particular.

German Type -212A non-nuclear submarines can make a wide range of missions, from anti-submarine warfare to anti-ship combat; assists special forces in surveillance and reconnaissance operations. Until now, Type-212A nicknamed “F-22 under the ocean” is the most modern and most powerful non-nuclear submarine in the world, they outperform the submarines in the same segment manufactured by other countries. create. The power of Type-212A submarines comes from three factors, the first is the stable operation and does not emit noise that makes them almost “invisible” under the ocean, second they are equipped with electrical equipment. modern death and finally a powerful arsenal. In the early 1990s, the German Navy sought a new submarine based on the improved Type 209 design, using an air-dependent propulsion (AIP) engine. The program officially began in 1994, when the German and Italian navies jointly developed a new conventional submarine, operating in the shallow waters of the Baltic Sea and the deeper waters of the Mediterranean. The two rather different requirements of the two countries were finally reconciled in a new design, eventually the new submarine with the Type-212A designation was officially born. On April 22, 1996, a memorandum of understanding kicked off the cooperation of building four identical ships to facilitate logistics and operations. In 1998, the German Government placed an order for the construction of four Type-212As at Howaldtswerke-Deutsche Werft AG (HDW) and Thyssen Nordseewerke GmbH (TNSW) of Emden. That same year, the Italian Government also ordered two submarines of this type. The German Navy ordered two additional refurbished submarines in 2006, delivered since 2012. These two are longer than 1.2 meters to allow more space for a new reconnaissance mast. In 2008, the Italian Navy ordered a second batch of submarines with similar configurations to the original ones. Some of the upgrades involve materials and software packages to reduce maintenance costs. In 2015, Italy announced plans to build two more. The Type-212A is a diesel-electric submarine that uses an AIP air-independent propulsion system, the first to be added to a Siemens proton-exchange membrane compression hydrogen fuel cell. It can travel at high speeds on diesel power or switch to the AIP system for slow and silent diving, and can stay underwater for up to three weeks, with little heat generation. When using AIP engines, they produce very low noise and diving times can be up to 3 consecutive weeks, far exceeding the maximum diving time of the Russian Kilo 636 or French Scorpene submarines. The drivetrain is also said to be vibrating, extremely quiet, and almost undetectable. Type 212A is approximately 57.2 m long and 6.4 m high; ships with diesel engine 1 MTU 16V 396; has a displacement of 1,524 tons when floating and 1,830 tons when diving; reaching speeds of 22 km / h when floating and 37 km / h when diving, a range of 15,000 km (at speed of 15 km / h); can dive for up to 12 weeks if using a snorkel; crew of 27 members. The tail is arranged with the letter “X” to help the ship rotate quite quickly under the ocean. Another notable design feature is the cross-section of the prismatic hull and a smooth transition from the hull to the sail, improving the stealth of the ship. The ship and its interior structures are made of non-magnetic materials, greatly reducing its chances of being detected by a navy’s magnetometer or magnetic mine. In addition, Type -212A is constructed from non-magnetic steel making it completely invisible to magnetic detectors (MAD) mounted on submarines, hunting aircraft and hunting helicopters. In other words, Type-212A submarines are completely immune to MAD equipment of the US, NATO or Russia. In tests, they can dive to a depth of 700 meters. With these features, the Type 212 outperforms the Russian Kilo 636 black hole or other Western ships of the same class. Weapons on the Type-212A submarine include 8 533 mm torpedo tubes. The catapult that can fire the optical fiber guided torpedo is DM2A4 together with the Blackshark torpedo. This torpedo has a range of 50 km, a top speed of 92.6 km / h. Future possibilities may be integrated cruise missiles The Type-212A is also equipped with an IDAS low-to-air missile system to combat low-range airborne threats. Short-range IDAS missiles (based on IRIS-T missiles) are primarily used to counter air threats as well as sea or land-based, or small, targets, developed by Diehl BGT Defense to fired from the Type 212A’s torpedo tubes. The IDAS is fiber-guided and has a range of about 20 km. A 30 mm automatic cannon called the Muräne to aid divers’ operations or to fire warning is also under consideration for an addition to the Type-212A submarine. The cannon, which could be a version of the RMK30 built by Rheinmetall, will be housed in a retractable mast that can be fired without the ship having to float. With a special design, it can operate in water depths only 17m and has 3 launchers for 3UAV reconnaissance. That allows it to get close to shore that no other submarine has been able to do yet. In the near future, Germany is planning to bring a longer range cruise missile to the Type 212A submarines.

The house located in Bac Ninh province has a typical structure of a tube house, narrow and deep (size 4x20m), with only two open sides before and after. One downside is that the works near 3 industrial zones have a lot of noise and dust. Therefore, architects have come up with solutions using green arrays to prevent dust and noise. Accordingly, the front of the house is planted with many layers of trees from low to high. It is not easy to use the depth of the house. Outside is a setback space to avoid dust, noise, also a place for parking. Next is the living room, inside is the kitchen. Stairs are placed in the middle of the house nestled to the side to create a well-ventilated space. Next to the stairs is a sky well that goes from the first floor up to the roof. The skylight is large enough and light enough to be planted with trees. Trees and light are the “materials” of the interior to soften the space. The master bedroom is located in front of the 2nd floor. Outside is a veranda and green garden. The private bathroom uses glass walls to save space and airy. The 3rd floor bedroom opens up to a green courtyard. This is an ideal space to relax, always filled with sunshine and wind Simple staircase with glass railing creates airy, light granite plastering steps for a light feeling. The dining room space is widened in view throughout the house to the front. In the interior, the floor, wall and ceiling materials use light colors to increase the lighting factor. Dark wood furniture creates contrast. On the front side, the upper floors recede gradually to create a space for trees and also create an airy space and vision./.
