Coast Guard Receives Its Second Air Cushion Vehicle for Karnataka | India News - Times of India

MANGALORE: When Indian Coast Guard's Air Cushion Vessel (ACV) H-198 glided up the pristine sandy shore at Panambur beach around noon on Monday, its arrival marked a major milestone in augmenting security off Karnataka's coast. Skippered by Commandant Amitabh Banerjee, H-198 became the second ACV to join Coast Guard's surveillance machinery in its district headquarters three after ACV H-196 that arrived here on September 22. Rajmani Sharma, Deputy Inspector-General, and Commander, Coast Guard Karnataka commandant Gulwinder Singh, skipper of ACV H-196, Commandant Rajender Singh Sapal, district plans and operations officer and personnel of district headquarters three were on hand to receive the ACV. Slippery slope at the beach meant Amitabh had to take H-198 for one more run on the Sea before he brought it ashore authoritatively and with aplomb. The two ACVs - will complement the four inshore patrol vessels that Coast Guard already has here, Rajmani Sharma said. With the fifth inshore patrol vessel Amartya, and a fast attack craft expected to join the fleet here next month, Coast Guard will be in a far greater position to thwart any sea borne incursion off Karnataka and Goa coasts, Rajmani said, adding these ACVs and patrol vessels can be deployed anywhere anytime based on need. Coast Guard, as reported in these columns earlier, will also have an advanced offshore patrol vessel ICGS Samarth based here once the dedicated jetty sought by it at New Mangalore Port becomes operational, he said, adding an India Coast Guard air enclave could also materialise at old airport at Bajpe near here where Chetaks and Dorniers will be based for aerial reconnaissance and search and rescue operations and other operational roles. Rajmani said the two ACVs that have reached here and that will be based here permanently will be commissioned in a gala commissioning ceremony to be held here soon. "We are in touch with our top brass and other dignitaries for this event," he said. On the other hand, ICGS Amartya will be inducted in to the Coast Guard here and sail back to Goa for its formal commissioning ceremony along with another vessel of the Coast Guard, he added.

No longer a problem with LCD TVs, thankfully.Early TV remotes used metal rods being struck by a tiny mallet in this same frequency range (before infrared remotes arrived) - push a button and you'd get a "ting" noise that was picked up by an ultrasonic sensor on the TV.Metal hangers scraping on metal clothes rods in department stores were really annoying, especially when lots of shoppers were doing it at once.And, of course, dog whistles, which could often be tuned to just above audible hearing range (which of course, would be lower in adults)
MUN Engineering Students 'pretty Excited' After Making Hyperloop History
A group of engineering students from Newfoundland and Labrador made history on Sunday, and may have made a breakthrough in new technology that could change the way we travel. The Paradigm Hyperloop team launched the world's first successful run of a hyperloop pod using air-bearing technology. In the process, they placed second in the SpaceX Hyperloop competition, competing against teams from all over the world.As the sun sets, we take home the 2nd place prize for speed, however, history has been made this day by proving the air bearing concept pic.twitter.com/l2FaztcqEG"Three years ago, I don't think I ever thought we would actually build a pod that was going to be internationally recognized, weigh 2,000 pounds, be 18 feet long and float on an air cushion down a vacuum tube," said Adam Keating, team lead for Paradigm Hyperloop."I think it's pretty safe to say that everyone in the car is pretty excited about this," he told the St. John's Morning Show as he and a number of his teammates drove to San Francisco from the SpaceX headquarters in Hawthorne, Calif.A hyper-what?A hyperloop travel system consists of a pod travelling through a steel vaccum tube. The pod travels through the tube on a thin bed of air, much like a puck on an air hockey table. Because there's little friction, the pod would be able to travel at speeds impossible for a car or even a train to reach.A fully realized hyperloop transportation system would take someone from St. John's to Corner Brook in 30 minutes.The idea was dreamed up by tech billionaire Elon Musk, whose company SpaceX organized an annual competition for university students to advance the technology and help make the dream a reality.Some of the Paradigm team - 15 students from Memorial University, one student from College of the North Atlantic and 14 students from Northeastern University in Boston - were part of the first competition in 2016, and ran a pod called Open Loop.They finished in the top 10, but they were determined to do better. They went home, they reorganized, and they spent the last eight months building the revolutionary Paradigm Hyperloop pod.And yes, they met Elon Musk.Only North American team in Top 3The Paradigm pod uses air bearings rather than magnets to shoot down the SpaceX Hyperloop test track. It's the first hyperloop pod in the world to use the technology."A lot of the other teams and a lot of other people basically ruled it out as an option because there just isn't proof of the technology at these speeds," said Keating.Their design was good enough to secure them a trip to California to test their pod in a competition against 25 other teams.After the initial test runs, they were one of just three teams chosen to compete in the finals, the only team in the top three from North America.Hyperloop pod run by team WARR pic.twitter.com/ntaMsoxkZEKeating said the winning team, Germany's WARR Hyperloop, was designed for speed - it sailed down the test track at 324 kilometres an hour."Their pod was much smaller, much lighter, designed to clamp to the rail and go as fast as possible," he said.Could see hyperloop travel in 5 yearsBut as far as realizing a hyperloop system some day, it could be argued that the Paradigm Hyperloop team are the big winners: Keating says the air-bearing technology would make a fully fledged Hyperloop system much cheaper.Regardless of what system ultimately becomes the standard, Keating says it won't be long until we're all flying through vacuum tubes in the blink of an eye."I think in the next five years you're going to see a hyperloop working in the world," he said.And that's just fine with him. After driving from Hawthorne to San Francisco and sitting in traffic for hours, he and the rest of the Paradigm crew in his car were eager for new transportation options."We were all joking about how we wished the hyperloop was built already," he said.
Technology: Flat Screen Future for Hdtv
By BARRY FOX in TOKYO The Japanese electronics manufacturers currently striving to make liquid crystal displays large enough to serve as wall-mounted TVs, may be beaten to it by a different technology. Canon is hoping to leapfrog the competition and produce flat TVs with wide, high-definition screens using a technology called ferroelectric LCD.Last week, Canon demonstrated a 38-centimetre prototype screen to New Scientist. The screen displays colour still pictures of a quality close to that of high-definition television (HDTV). The largest conventional LCD prototypes are around 42 centimetres across, and manufacturers are having a hard time making them bigger (Technology, 16 May). 'Once we have solved production problems for medium-sized screens,' says Hirokuni Kawashima, head of Canon's FLCD team, 'there is no theoretical limit on the size of panels we can make.' The company has just committed 100 billion yen (nearly £500 million) over the next ten years to building factories that will mass-produce large FLCD panels. At the end of this year, the company will launch a desktop wordprocessor with a 38-centimetre monochrome FLCD screen. A factory for producing tens of thousands of 1-metre or larger colour screens each month will be operating 'a little bit before the end of the decade', says Kawashima.Last October, Canon demonstrated the first prototypes of 38-centimetre computer screens using FLCD (Technology, 26 October 1991). When Canon suggested that FLCDs could also be used for HDTV screens, the idea was not taken seriously by the television industry. TV requires wide ranging scales of greys and colours, but ferroelectric material can only be switched between two states:on and off.Both conventional and ferroelectric LCDs work by shifting the polarisation of light. The liquid crystal is sandwiched between two glass plates, each of which carries a polarising filter. The filters are aligned at right angles to each other, so no light can get through under normal conditions. In a conventional LCD, applying an electric field to the liquid crystal makes the molecules line up in such a way that they shift the polarisation of light through 90 degrees. The light can then pass through both filters.The electric field is applied through transparent electrodes made of indium tin oxide printed on the inside of the glass. These also define the picture elements, or pixels, that make up the screen. When the field is removed, the molecules fall back into a random arrangement.In an FLCD, the molecules can be moved by a pulse of electric field between two stable positions: one in which the molecules shift the polarisation of light to let it through, and one in which they do not. So the FLCD has a memory: once the molecules have been switched, they remain that way until a fresh field is applied. This saves on electric power, because only those parts of the picture which move need to be switched.Canon's ferroelectric material is a mixture of 20 different low-viscosity liquid crystals containing fluorine, but the exact recipe is a closely guarded secret. The glass plates of an FLCD screen must be spaced just 1.5 micrometres apart. The spacing must be accurate to the nearest 0.05 micrometres - one-thousandth the width of a hair. Canon achieves this accuracy by coating the glass plates with a layer of insulating material one molecule thick, and peppering the gap with transparent spheres of insulating material which act as spacers.The plates are held in position against shocks by an air cushion mount.Canon's latest prototype has pixels as small as 0.2 millimetres; a 38-centimetre screen is therefore 1280 pixels wide and 1024 pixels tall. This resolution comes close to that of HDTV. Canon's future HDTV screen will use a stretched screen format with 1920 pixels in each of 1152 horizontal scanning lines.Each pixel is made up of four smaller cells, which are combined in monochrome displays to create four shades of grey and in colour displays to create 16 colours. But TV images require subtle gradations of light and shade.The company has developed digital circuits which analyse the colour required and compare it with the colours available; the circuits then switches on a jumble of pixels to create a mix of colours which fools the eye into seeing colours which are not in theory available from the screen.
How to Choose the Right Brush for Your Hair - Times of India
Normal plastic combs are not very gentle to hair because of its sharp edges, which acts like "knives". Split hair is often associated with low quality plastic combs. Wooden combs are anti-static and therefore one can easily comb their hair without entangling it. Too much static can hurt the hair profile and make it rougher and brittle. Moreover, the main idea of using a comb/brush is to distribute the natural oils evenly across the scalp from root to the end. Thus the right kind of brush for your hair is the one that reaches your scalp smoothly detangling one's hair from root to the tip and provide a natural shine. TYPES OF HAIR BRUSHES 1. Round Brush: The big round brushes offer smoothing and volumizing benefits for thick, moderately straight and long hair. These brushes are generally used to create soft waves on most hair types 2. Paddle Brush: Large, flat and wide, paddle brushes are versatile and a must have. This brush is great for detangling hair strands and keeping hair frizz-free. This is a useful brush & can be used to smoothen the natural waves. This saves a lot of styling time by managing the hair from root to trip. 3. Vented Brush: A vent brush lets air pass through it. These are best for short hairstyles, as they speed up drying time and ensure that you don't over-dry short locks. 4. Cushion Brush: This category of brushes include the oval/round -shaped cushioned brush for simply brushing out hair. This is specifically for dry / slightly damaged hair which has a tendency of breakage. The cushion induced base provides an air cushion that's used exclusively for long hair. The bristles are aligned in a cushion base which contracts anytime they meet resistance; hence, they prevent long hair from being stretched, split, or broken. 5. Wide Tooth Comb: Wide-Tooth Comb is a comb with the teeth far apart that detangles your hair, can also be used when washing your hair to distribute conditioner and shampoo. Best used to untangle knots within your hair. Works with all hair types. 6. Normal Comb: Normal Comb; just your normal every-day comb that you can get in varying sizes. Good for smoothing your hair out and making it look sleeker. Inputs by: Dr. Apoorva Shah, Trichologist and the founder of Richfeel Health and Beauty Pvt. Ltd.
Design Scheme of Multi-channel Voltage Measurement Based on Stm32
Design Scheme of Multi-channel Voltage Measurement Based on Stm32
This design proposes a design scheme of multi-channel voltage measurement based on STM32 chip, and the measurement range is between 0-10V. The built-in A / D of STM32 samples the multi-channel voltage values to obtain the corresponding digital quantity. Then the corresponding analog voltage value is obtained according to the proportional relationship between digital quantity and analog quantity, which is displayed by TFTLCD display equipment, and the multi-channel collected data is stored in SD card.1. IntroductionIn recent years, data acquisition and its application have attracted more and more attention, and data acquisition system has developed rapidly. It can be widely used in various fields.Data acquisition technology is one of the important branches of information science. Data acquisition is also a process of obtaining object information from one or more signals. Data acquisition is an important link in industrial control systems. It is usually realized by some single chip microcomputer systems with relatively independent functions. As an indispensable part of the measurement and control system, the performance characteristics of data acquisition directly affect the whole system.Voltage measurement is the most universal. It is of great significance to study and design methods and instruments to improve voltage measurement accuracy. In the design of voltage measurement, single chip microcomputer as controller is the core of the whole design. In addition, there must be an analog-to-digital converter (ADC) in the design. ADC is used to directly collect analog voltage and convert analog signal into digital signal. It directly affects the accuracy and speed of data acquisition.2. System overviewThe microcontroller of this design adopts STM32 single chip microcomputer.STM32 Series MCU is designed based on the Cortex-M3 core of arm company. Its clock frequency reaches 72mhz. It is a high-performance product among similar products. It has the advantages of high performance, low cost and low power consumption. It is a good choice in embedded application design. The A / D converter in the design adopts STM32 built-in ADC. STM32 ADC is a 12 bit successive approximation analog-to-digital converter.It has up to 18 channels and can measure 16 external and 2 internal signal sources. The A / D conversion of each channel can be performed in single, continuous, scanning or intermittent mode. The conversion results can be stored in the 16 bit data register in left or right alignment. The maximum input clock can reach 14mhzThis design can measure the voltage value of 8 channels, the measurement range is 0-10V, and the display error is ± 0.001V. LCD displays the voltage value and waveform in real time, and microSD card synchronously stores the data. The system principle block diagram is shown in Figure 1.Design scheme of multi-channel voltage measurement based on stm323.3 LCD control circuitThe LCD used in this design is 2.4 inches, 320 & times; 240 resolution. The LCD module is controlled by the FSMC interface of STM32.FSMC (flexible static memory controller) can be changed into static storage controller. It is a unique storage control mechanism of STM32 series high storage density microcontroller with internal integration of flash of more than 256Kb and suffixes Xc, XD and Xe. By setting the special function register, FSMC can send corresponding data / address / control signal types according to different external memory types to match the speed of the signal, so that STM32 series microcontrollers can not only apply various external static memories of different types and speeds, Moreover, it can expand a variety of different types of static memory without adding external devices, so as to meet the comprehensive requirements of system design for storage capacity, product volume and cost.In STM32, one end of FSMC is connected to core Cortex-M3 through internal high-speed bus AHB, and the other end is an external bus for extended memory. After the access signal of the kernel to the external memory is sent to the AHB bus, it is converted into a signal conforming to the communication protocol of the external memory through the FSMC and sent to the corresponding pin of the external memory to realize the data interaction between the kernel and the external memory. FSMC acts as a bridge, which can not only convert the signal type, but also adjust the signal width and timing, so as to shield the differences of different storage types and make them no difference to the kernel.FSMC can connect devices such as nor / PSRAM / NAND / PC card, and has FSMC_ A [25:0] has 26 address buses and FSMC [15:0] has 16 data buses. In addition, the extended storage space of FSMC is divided into 8 blocks. Select the block of the operation through the address line. In this way, the LCD will operate as a memory with one address space.3.4 SD card drive circuitThe SD card used in this design is microSD, also known as TF card. MicroSD card is a very small flash memory card, which is mainly used in mobile phones. However, due to its small volume and the continuous improvement of storage capacity, it has been used in GPS devices, portable music players, digital cameras and some flash memory disks. The pin diagram of microSD card is shown in Figure 9.MicroSD card, like SD card, has SPI and SDIO operation buses. Compared with SDIO bus, SPI bus has simple interface, but its speed is slow. We use SDIO mode.MicroSD card has 4 data lines in SDIO mode.In fact, microSD has 1-wire mode and 4-wire mode in SDIO mode, that is, 1 or 4 data lines are used respectively. Of course, the speed of 4-wire mode is faster than that of 1-wire mode, but the operation is more complex. The 4-wire mode of SDIO is used in this design. The hardware connection diagram of microSD card is shown in Figure 3.STM32 MCU Chinese official websiteSTMicroelectronics / St / STM
How Does Temperature Affect the Speed of Sound?
How Does Temperature Affect the Speed of Sound?
As other answers show, the speed of sound is slightly influenced by temperature.Much more interesting is the influence of gradients in temperature! The usual distribution of temperature at different heights is: high at ground level, decreasing upwards. This profile, with slightly higher sound velocity at ground level causes wave fronts to curve upwards. Sometimes the temperature profile is inverse, from ground level to a certain height, in the order of hundreds of meters. This inversion layer acts as a reflector, causing sound to propagate over much larger distances.It is not the speed as such, but the differences in speed that have important influence on sound propagation.1. How to increase my running speed?No, leaping prime does now not make you a quicker runner. Speed is muscular so you will do whole frame paintings along side plyometrics, which can be exceptional varieties of bounding and leaping to construct explosive force. To get greater at going for walks you ought to run. If you are employed on lifting and doing the plyometrics you are going to have the groundwork to upgrade your going for walks. What form of going for walks are you running for? If it's soccer then you definitely will have to coach for brief bursts of velocity. If it's one other game you have got to appear on the distances required on your game. A huge aspect of velocity it response. That manner the begin. Whether it's out of the blocks in a race, or attending to a fly ball within the outfield. Speed is vigor so that you ought to be ready to loosen up rise up tall, maintain your elbows at ninety levels, swing them directly entrance to again, and now not throughout your frame. Land at the balls of your ft.2. Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?Mass of 275 litres of Water divided by 5 minutes x 60 seconds = Time of 300 secondsMass Flow Rate of 0.9166 litres per secondThis is excessive amount of water in Speed or Velocity to fill a bathtub in 300 seconds. See IPHE & CIBSE CoP & Technical Guidance on maximum flow rate for 15 mm smooth wall copper pipework. The water pressure is another factor is consider.Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?.3. Not getting the download speed I should be getting?you download a file to what ? a phone or a computer? ethernet or wirelessly ? you need to be more clear on how to ask a question, even with my godlike powers i cant read your mind4. Need help gaining speed/trimming fat?challenging task. browse in google. that will may help!5. Why are people so insistent that speed of light is constant for all observers and is the maximum traveling speed?In special relativity, when the speed of light is constant for everyone, time can be different. When different travellers or observers have light remain constant, their time can change to allow for this. So try to wrap your head around the fact that different observers can have differences in time, and this allows the speed of light to remain constant for all observers.6. fur nice fan motor Polly have to be smaller to make the fan go faster?Motor pulley larger or driven pulley smaller will increase speed7. What are the technical factors in a processor that determine its speed?Clock Speed of the Processor and its primary cache size determines its speed in terms of throughput8. Is faster than the speed of light possible?well ist just a theory so it could be or couldnt be true.....einstien said if we could go the speed of light then we cold time travel...other people say it is still expanding....what i want to know is how can all of that crap fit into somthing the size of a pin head lol.9. How to train for faster picking speed on guitar?Assuming we are talking about alternate picking, there are basically two exercise methods for building speed.The first and the better known one is to start slow. Set your metronome to a comfortable tempo and play the exercise a few times. Then go up 2 bpms or so and repeat. Continue alternating between plus two and minus one. Back down some 10 bpm when you hit your limit and work your way up from there again. You can go up 10 bpm or so from time to time just to see how it feels. The second one is to practice in bursts. Start with two notes and play as fast as you can. Then add the third and continue from there. This method is not as well known as the first one but is every bit as useful. You can also start from the most difficult spot on the exercise and add notes on both sides.Practicing scales only is probably not the best way to go. There are specially crafted exercise sets to build speed that isolate common patterns. Troy Stetina's book Speed Mechanics contains one such set.In terms of technique, on your left hand, only apply enough pressure to avoid buzz. You will get tired very quickly if you exert more force than necessary. The lighter your left hand touch is, the easier it is to play fast. It's easier said than done but that's the whole idea of practicing.On your right hand, I would not worry that much about wrist vs. elbow unless you are aiming for Guiness speed record. Wrist movement is probably a bit better but there's nothing wrong with a combination of wrist and elbow. Guitarists argue about it all the time but there are superb guitarists in both camps which proves that both techniques are equally viable. Just avoid finger movement, it does not work for fast playing
