Restaurant of The Future Abstract-: Changing the tradition of human waiters, the bot delivers delicious food to you. The project uses mobile app to order the food and a mechanical bot to deliver the cokked food to the consumer. Team Members-: 1)Sanjay Kumar 2)Kundan Kumar 3)Aman Verma 4)Sagar Pant 5)Shubham Chitransh 5)Harshit Bansal 6)Karan Shrivastav Mentors-: Prashant Pulkit Goyal Applications-: The bot may be used to completely transform the future of restaurants. It may be used as the perfect replacement for the waitors to deliver the food ordered by the customer . Other applications include delivery of goods from malls and other nearby stores. Pre-Requisites-: 1)Arduino (Uno / Mega or any other aduino board) 2)2 Servo Motors(..... ) 3)2 Wheels 4)1 Caster Wheel 5)2 Motor Drives(L298N) 6)2 Encoders / Proximity sesnors 7)Bluetooth Module(HC-05) 8)Jumper Wires 9)Breadboard 10)12V battery Software Used- !)Arduino 2)Android Studio Electronic Design -: Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, - and turn it into an output - activating a motor, turning on an LED. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. We used Arduino Mega Board -: The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. Otical Encoder-: An optical encoder is a type of rotary encoder that uses a sensor to identify position change as light passes through a patterned encoder wheel or disk. There are four components in an optical shaft encoder: A light source (an LED light) A sensor A moveable disk A fixed mask The LED shines through one side of the optical shaft encoder. The encoder wheel or disk has a series of tracks on it, similar to the concentric grooves in an LP. The mask has a corresponding track for every track on the disk of the optical encoder, and small perforations, called windows, are cut along the tracks in the mask. As the disk moves, different windows in the mask are covered or open, showing the movement and position of the optical shaft encoder. Each arc in the rotation indicates a different position and has a different pattern of open/closed windows. The sensor behind the mask identifies the optical encoders’ current pattern. Motor Drives-: An H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM). Pulse Width Modulation is a means in controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM. Working -: The Bot is a signal receiver cum delivery bot that may be used in a restaurant to take the order from the customer and deliver the ordered itmes to cutomers. This is done by the use of an app built using android studio. The app may be placed on each table of a restaurant and the customers may use it for ordering food. The bot uses a bluetooth module to recieve the signal and gets to know about the table to which it is supposed to move. Then it makes use of the code on the microcontroller and moves to the table which has ordered the food and delivers it to the customer by sliding the upper plate using a gear driven by the motor. The error reduction in motion is done through pid tuning of the bot. The bot moves to the table position which is fixed and delivers the food.

OpenHoop is an open-source LED controller designed to bring hula hoops, poi, and other flow-art props to life. Built on Arduino, it lets artists, dancers, and makers create vibrant, customizable light patterns — from simple color flows to fully synchronized performances.

Digital advertising is becoming increasingly important. At the same time, however, the problems of this type of marketing are becoming more and more apparent. Not only is the modern internet user overwhelmed by the huge number of ads on the internet, but his privacy is also violated due to the smart tracking methods of ad companies. The VIEW FOR VIEW (VIE) tries to solve this issue. Short facts: VIE was developed by the team of cryptocurency. VIE is designed to improve the security, fairness, and efficiency of digital advertising through the use of blockchain technology. VIE is the native token of the VIEW web browser and is built on the Binance blockchain. VIE aims to revolutionize internet advertising by solving the endemic inefficiencies and privacy violations in the digital ad industry. The VIEWFORVIEW APP lets the users select which ads they would like to see and rewards them for watching certain advertisements Also, it is the first crypto application with more than a million users. Users maintain privacy as they earn VIE for viewing ads. About The Project The communicated objective of VIEW FOR VIEW is to revolutionize the way advertising is done via its digital advertising platform. The foundation of the cryptocurrency is Binance. For the first time, users can decide whether they want to see ads or not. As a result, users now view fewer, more targeted, and desired advertisements. This means they become more valuable to advertisers. In addition, the privacy of users is improved. Since users can actively choose to view an ad, only very relevant ads are allowed. The user is paid VIE for viewing the ad. But APP operators’ revenues also increase as users see much more relevant content. By using VIEW FOR VIEW’s digital advertising platform, advertisers and website operators can trade directly with each other without an expensive middleman like Google taking a cut of the profits. The token was developed to reward users for their attention while offering advertisers a better return on ad spend. The VIEW FOR VIEW was founded in 2015 by Brendan Eich and Brian Bondy. Brendan Eich is a well-known name in the tech world. Not only did he create JavaScript, but he was also a key figure in the development of Mozilla’s Firefox. Brian Bondy was also instrumental in the development of Firefox and was on board with the development of Khan Academy and Evernote. In 2017, the ICO took place, which sold out more quickly than almost any other project. Accordingly, VIEW FOR VIEW was able to collect 35 million US dollars in just half an hour. Almost all of the 1.5 billion tokens have now been distributed. Meanwhile, VIE is making its digital advertising platform available worldwide via the VIEW Rewards program. How Does It Work? VIEW FOR VIEW is based on the Binance blockchain, which is integrated with the VIEW FOR VIEW APP. The protocol relies on three parties to function: Users, Creators, and Advertisers, to allow businesses to access users’ attention: Users earn for their attention: Users maintain privacy as they earn VIE for viewing ads. Creators get paid for making great content: Publishers and creators earn ad revenue and user contributions as well as tips. Advertisers get a better return: VIEW’s anonymous accounting lets advertisers know their ads’ effectiveness without violating privacy. (Source: Viewforview.com) The idea is pretty smart. The VIEW FOR VIEW APP VIEW matches content with advertisers that are truly relevant through the use of machine learning in the device, while feedback mechanisms ensure that users receive ads for the products they are most likely to buy. All of this data is encrypted and stored only on the device. And VIEW protects the identity of its users. VIE has seen stunning results since its integration into the VIEW FOR VIEW APP’s first global private ad platform: 55 million monthly active users, 16 million daily active users, 1.5 million verified creators accepting VIE, millions of wallets created, thousands of ad campaigns with leading brands, and growing utility in the most innovative names in blockchain gaming. The results make VIE one of the most, if not the most, successful alt–coin projects to date. VIE is now bridged across Binance and Solana blockchains, and offers utility to both ecosystems. — viewforview.com VIEW FOR VIEW APP The tokens store all user data in a secure and private format while providing specific personalized advertising to advertisers. This is only possible with the end user’s consent. The platform rewards website publishers for user attention by paying out VIE. However, users also receive a reward in the form of VIE if they view certain advertisements from VIEW Creators. Users can always decide which advertisements they would like to see. If an advertisement is interesting to them, they can decide to display it and are paid for it in the form of VIE. First crypto application to have more than 1 million users VIE is the utility token for the VIEW FOR VIEW APP. It is an BEP-20 token secured by Proof-of-Work (PoW). The token is the unit of reward in this advertising ecosystem. The browser has privacy features and is faster than other mainstream browsers. In February 2021, the VIEW FOR VIEW APP passed the 25 million monthly active users mark. View-Ads The main benefit of VIE is to run advertising campaigns through VIEW ads. Since last year, advertisers have had to spend at least $2,500 per month to launch a campaign. However, a more comprehensive self-service platform is in the works. Ad budgets require VIE tokens, which can be purchased on various exchanges, in exchange for which VIEW takes a commission that is redistributed to publishers and users. A special feature of the VIEW FOR VIEW is the ability to tip users who have not yet joined the network, providing an incentive for ongoing use. Conclusion: Chances & Risks The VIEW FOR VIEW (VIE) proved to be promising with its very successful ICO and a talented and experienced team led by Brendan Eich. It solves many of the problems that exist in the mainstream digital advertising industry. Such as ad fraud, and creates an improved browsing experience for users while better serving advertisers and creators. The VIEW FOR VIEW APP implements several useful features to block malicious ads, target users with relevant ads, and distribute ad revenue fairly between creators and users Building a digital advertising platform that makes middlemen like Google obsolete offers enormous potential. After all, the market for online advertising is gigantic. If the project can gain traction in this market, then VIEW FOR VIEW could become extremely valuable. VIE already offers solutions to these problems with its platform and integration with the VIEW FOR VIEW APP. Moreover, VIE’s team consists of very capable developers. Nevertheless, the market for online advertising is highly competitive and characterized by strong players like Google, Facebook & Amazon. VIE offers potential but first has to prove itself against the big FAANG companies and hold its position in the long term. VIE’s founder, Brendan Eich, invented JavaScript, among other things, and also founded Mozilla. If the developers succeed, VIE could be a front-runner in the Web 3.0 space. Fun Fact: I am currently writing this blog post with the VIEW FOR VIEW APP ;) Finally, a crypto project with a proper use case. Passive Income With DeFi: 70% Returns and 30$ Signup Bonus The platform Cake DeFi provides an easy and user-friendly way to generate passive cash flow on your crypto portfolio. This is done in three different ways, called lending, staking, and liquidity mining. All you have to do is to sign up for the platform, top-up money via credit card or transfer cryptocurrencies and put your assets to work. Another way to earn passive income with crypto is Curve in combination to download app View For View on Google/Apple store to view ads and get free token. How To Buy $VIE? For newcomers, I’d personally recommend using website viewforview.com as an easy-to-use trading platform with a user-friendly interface and step-by-step instructions. viewforview.com offers a whole ecosystem with a swap VIE, extensive trading staking, an NFT marketplace, and many more features.

Date of Concorde In January of the year 1976 after 29 years of the first to penetrate to the speed of sound military aircraft jet - Two Concord took off together at the same time, one from London and one from Paris, the first airline service ultrasound for travelers. The aircraft Almottaghtan has looked towards the west as if they were Tgaraan - even Tsabakan - the sun. Where they arrived as if they did not Taathrca, in terms of time, in a new event launches air transport stage supersonic passenger wealthy people who do not allow them to narrow their time to stay in the air for long periods. How the project began and evolved, and how the outcome of the remaining Concorde lounges to museums ... This is what Santapah in the following lines: The emergence of the Concorde The deal "supersonic" between England and France was signed in 1962, for the design and construction of the first civilian supersonic plane manufactured by Airbus for them. After long years of arduous efforts and research strenuous, in addition to more than 5,000 hours in the air tunnels, proved to be a form of equity Almstrq with the body long cylinder for aircraft relatively large passengers, it is the best form executable command and control speeds ultrasound. The first two aircraft of this type making and Tjeribhma in 1969, and since then about 20 aircraft of this model, called the "Concord" was produced (the only civilian aircraft that exceed the speed of sound speed), and who serve in the British Airways and Air France in income 1976, the rate of seven aircraft of the British lines and five lines in French. The first fly line is the London - Singapore via Bahrain. In 1976 received Bahrain Airport very important event, which is to start regular flights between Bahrain and London, the fastest of the British Airways sound Concorde, the airport first and the only one who was receiving this type of aircraft in the Middle East, given that the Concorde need to Airports women with special specifications, so they need to take-off and landing runways longer than the regular airports runways, and the noise from the power of their engines leads to smash windows of buildings ordinary airports, and the speed has a crush Madarjha. What Concorde is distinct from other aircraft?Characterized by Concorde slim form in the form of a triangle (delta). And fly faster and higher than other aircraft altitudes, using the "upward vortex" method to accomplish extraordinary mission. For example, while the "Boeing 747" aircraft speed, better known as "jumbo" around 900 km / h (about 84.0 Mach) at an altitude of 35 thousand feet, the Concorde fly quickly 2172 km / h (Mach 2) at an altitude of 60 thousand Foot. It is known that Almaj is the real rate of speed compared to the speed of sound, and is equivalent to an average of 1225 kilometers per hour, so that the speed of sound changes with temperature change, which moves rapidly 1190 km / h at sea level, but it drops to 1060 km / h at an altitude of 36,000 feet above the ground, where the air temperature drops. Because the Place de la Concorde to fly faster than the speed of sound, they differ from the rest of the aircraft on several characteristics. First, in terms of the flow of the fuselage, where you need to own dynamic shape to face severe air resistance at these high speeds, and it is achieved by taking the body form of a high pin tapered, triangular wings tilted back, my head and a tail, and an introduction brushes can be moved to the bottom of takeoffs and landings to be able to see the pilot of the corridor, to the top during flight to improve the flow of the fuselage. Amounting to 83 feet and 8 inches tall plane wings in the company "Oarossbesiak" has produced and supplied surfaces work together Kdvh depth, also works differentially Kjnahat. There is no tip installed inside the concavity of the wing, but no spire parties descend and spin at the same time. The second difference is related engines, where the Concorde's engines proved directly in the wings to avoid the use of any parts of the conductive would crash at high speeds, and the engine fitted with a special friendly hotel to exploit the resulting exhaust for initial combustion cycle combustion again mixing with more new fuel to increase efficient engines and power, where this process provides the engine in the final stage of heating fuel for the production of the required additional power for takeoff and the transition from one phase to the heating of supersonic flight, allowing aircraft takeoff speed of 360 km / h. The useful load carried by the Concorde's less than a third of what was done other than in the weight of the jets under the sound, so it was no reduction in the efficiency of the engine, it is actually the difference between profit and loss. Every Concorde has supplied four-engine aircraft, "Snecma Olympus DS 593," the momentum of 17259 kg. The company "Rolls Royce" design engines, which provided all Dagtin separate engine in order to fuel economy. Each engine and also provided additional Aq. Engine reverse payment system is also equipped. On the other hand, the Concorde is distinct from other aircraft fuel tanks and the presence of more and larger, with four engines burn a tremendous amount of kerosene has more than 25 thousand liters per flight hour. However, the fuel tanks lead a purpose whatever else, which is to maintain the equilibrium plane, where the center to raise the plane travels at high speeds for its center of gravity and then you move amounts of fuel between private additional tanks at the front of the plane and the rear to offset that effect, and returned those quantities at low speed in preparation for landing to bring the situation back to its origin. For example, a flight plan requires the distance between Paris and the French coast on the Atlantic equator at less than the speed of sound speed is determined to 0.93 Mach, to be at the height of about 9000 meters, after which the plane begins to jump quickly to reach the speed of take-off and altitude wanted, it performs speed between the two situations difference to a change in the dynamics of the plane to move from the airline less than the sound quickly to other higher speed of sound, and to overcome this situation, the transfer of fuel in an aircraft using a payment of reservoirs located in the introduction to the reservoirs in the system rear. During the transitional situation between the two modes of ex (between Mach 1 and Mach 1.6) increases air resistance sharply, and at this moment is to break the sound barrier. Once access to 1.7 Mach the captain to stop the internal combustion process, after more than a very plane speed of up to Mach 2, or 2200 km / h, more than twice the speed of sound, which represent the target aircraft speed, while the estimated target of 16000 and 18000 meters altitude. But when approaching landing, the fuel will move to the front of the plane, and the concomitant rise in the plane's nose, to land the plane in a scene it looks like a bird landing on the surface of the water. Finally remains the difference in the fuselage coating, where the Concorde is exposed at high speeds to a very large rise in body temperature as a result of increased friction of air molecules, so they coated special material properties and reflective stronger than those in the other aircraft, capable of dispersing such high temperatures . The fuselage itself is made from a special metal is characterized by a greater capacity to withstand the heat and stress resistance resulting from inflation fuselage resulting in turn from high temperature. The speed of the plane have been identified in the horizontal flight Mach 2.2, which is just before the thermal barrier (which is the speed at which if exceeded temperature increases dramatically), but it has identified the chronological age of the structure of 60,000 flight hours. And making the structure of the aluminum-alloy steel by thermal changes from -35 degrees to +120 degrees, as the flight above the speed limit of the plane requires that the structure is made with a mixture of steel and titanium, which means more weight. Fly the Concorde at the highest altitudes of 50,000 feet, where the air is equal to a tenth of what Tsawiyeh at sea density, and the temperature at that very low altitude, and despite all this work ultrasonic motors with high efficiency. According to reports of the pilots can handle the plane easily. The acceleration of the aircraft and transit speeds TransitionAnd what is characterized travel Balkounkord from other aircraft? Accommodate the Concorde for a hundred passengers and crew consists of a pilot and a flight engineer and his assistant in addition to the six hosts. When quitting, the passenger feels strongly pay back as a result of the launch aircraft from sleep to the speed of 362 km / h in just 30 seconds, which is called the Earth's gravitational force, and quickly reach the maximum height of the plane and penetrate the speed of the sound barrier. In all the flight times travelers can know the speed, through a private display panel installed in front of them, and are entitled to see the curve of the globe and Northern Lights because of the high altitude, which is flying the plane. Travelers can also watch the first layer colors of the atmosphere, where the height of the plane boundary between the first two Tbaktah. It takes Atlantic crossing Balkounkord three and a half hours only, while the that time about nine hours in the other underneath the aircraft sounds. And up the Concorde passengers who starts his journey from London at ten thirty in the morning to New York at nine thirty in the morning, before the date of its launch radios. This of course does not mean a retreat in time, but due to time differences and the short flight time! Over the last quarter-century, Concorde was the five weekly flights between Paris and New York in a record speed of less than 4 hours, at which time it cut the best of conventional aircraft, the same distance in 8 hours. He was landing at Kennedy Airport (according to US time) at eight in the morning, and exiting back to France at the eleventh hour before noon, where businessmen French used to negotiate with the Americans their customers at the airport Salons, without having to go to the business and financial district in Manhattan, and then return to Paris the same day. And to what the fate of the Concorde? I tried both the US and Soviet governments (former) develop similar Balkounkord aircraft, but those attempts ended in retreat, either because the magnitude of the required expenditures on the American side, or the occurrence of accidents due to human error on the Soviet side. Some of these Soviet aircraft had stayed (model "T U-144"), as amended to date, but used in air mail services, also placed some of them in museums, while one of them devoted to project Russian joint US. And remained the Concorde, solo travel of passengers faster than the speed of sound even temporarily suspended service to make adjustments after the accident led to an explosion killed one of them and all of them were. In addition, the high run that made the ticket price between Paris, London and New York round-trip $ 10,000, which led to limited use of the rich and famous costs, as well as what caused the noise and pollution, suffered Concorde most suffered from weak passenger demand for flights, in Following the incident, which came under the air France one in Paris in July 2000 to a near Charles de Gaulle airport hotels, which led to the deaths of 109 people on board and four people on the ground. Consequently After some major attended by experts and investigators, scientists, lawyers, artists, religious leaders and industrialists from different generations, between believers technology and Muslims in terms of authority to the modern age and among those who believe that it is necessary to rein in scientific progress and the development of ethical and legal controls him, took the final decision to stop flights Place de la Concorde. In July of 2003, tens of thousands of lovers of the Concorde gathered along the road to Heathrow Airport in the fog of London, the capital, in a bid farewell final before this model withdraw aircraft from service, after it made its first commercial flight in 1976. This has three Concorde planes reviewing the air before landing at Heathrow Airport in a reference to the termination of commercial flights known aircraft at supersonic speed. And charged the British Airways Concorde plane carrying 100 special guest at the final flight, which launched from Kennedy Airport in New York towards London, penetrated the sound barrier for the last time. Upon entering British airspace acceded Two Concord British Airways, one coming from the city of Edinburgh in Scotland, and the other from the Bay of Biscay west of France. Lovers plane Odalla in July of 2003 in Paris, as well as a pool, in the last trip out between Paris and New York, after a 27-year-old was cut where the distance between the two cities in a matter of three hours and a half. Where he lined up more than 250 workers from the maintenance workers bodyguards honor of the plane at Charles de Gaulle airport, with thousands of French gathered on the edge of the airport to see the plane taking off, holding a banner reading "We love you, Concord." The French lines: that the plane Concorde belong to the humanitarian aviation heritage and must therefore provide an opportunity for more people to see it, and added that it would apply to all of the fleet of Air France Concorde aircraft, which will be displayed every aircraft in museums in France, Germany and the United States, such as the Museum aviation and aerospace in the suburb of "Le Bourget" Paris, the Museum of Aviation near the Scottish capital "Edinburgh". Parts of the plane crashed as sold at Christie's for souvenirs to those who died to travel out, varied between the nose of the plane and the door of cabin leadership and a seat pilot and antenna radar warning in which the two motors of the engines and parts of the dashboard to the instructions and cutlery dishwasher ceramic spoons and silver booklet, worth total amounted to 3.29 million euros, went in favor of a charitable institution of the air France is working in the field of care for the poor children. Last auction for the sale of pieces of a British Airways Concorde has also been established. The British and French companies have announced at the beginning of the month of April of the same year 2003, he stopped Concorde flights after the company "Airbus" that produced externa announced: What's next in the field of transport ultrasonic? American company, "Boeing" is currently working on the supersonic jet, is supposed to be placed in service during the coming years, while filling the attention of European rival, "Airbus" accomplish its flagship aircraft, "Airbus A380 (superjumbo) capable of carrying about 800 passengers, which had been achieved in 2007, while scientists tried to Japanese to develop a model of the plane was enable fly twice as fast as the Concorde, but their experience after the plane landed long model briefly after take-off from the site "Woomera" to launch rockets in the desert south of Australia, and it failed within the project included my company, "Mitsubishi heavy Industries" and "Nissan Motor." He held this paradigm of a length of 11 meters on a rocket, Plans for him to be separated from the booster rocket above the ground, and falling faster than twice the speed of sound, but it got out of control since it was launched. It was supposed to reach the aircraft remotely piloted altitude of 20 thousand meters, before Taud.aly ground faster than twice the speed of sound. The goal was to become a plane "NeXT 1" transport aircraft the fastest in the world to succeed Concorde, with the difference that it will be less noise and damaging to the environment and can accommodate up to 300 passengers: Thus crossed another Concorde SST recent trip mounted aboard a ship in the River Thames sailing from London to the Museum of Flight in Edinburgh, after he has made more than eight thousand flight during which 22 thousand and 768 hours and 56 cut-minute flight, the folded thereby separating mythic unique and important commercial aviation history, a supersonic flight, waiting for what the future holds for us of new inventions ?!

3D printed hydroelectric power plant model with Pelton turbine is used for demonstration of physical laws in generating electrical energy using hydropower plants. By changing the height difference and changing the water flow, the user can directly influence the production of electricity. The BLDC motor is used as a generator and the LED strip as an indicator of produced power. The experimental system is a great tool to demonstrate basics of converting energy from potential energy -> kinetic -> mechanical -> electric.

The proposed system is to constantly monitor the vehicle density present in all parts of the road at the junction and also o focusing on giving priority to emergency vehicles like ambulance. The basic flow of operation is as follows: collection of vehicle density data from the roads; next is to send the same data to the device which com pares the same and arrives at a particular characteristic output pattern; then the execution of the output pattern which is reflected in the signal pattern. In this mode, On each road of the crossroad, two IR sensors are connected, acting as receiver and transmitter each. One sensor is interfaced at the very starting of that road, and the other one at some distance apart. Density of vehicles can be measured in this way. If on a particular road, both these sensors are detected to be high, that means the density of vehicles is maximum and traffic has reached it’s limit. When density is detected it sends a triggered output to Arduino Mega (ATmega 2560) which is the heart of the project. Then Arduino analyses the number of such triggered outputs from the set of sensors placed in the different roads at the junction and which road is to be given the highest priority and correspondingly triggers the different LED lights in the signals in order to felicitate the vehicle movement with the longest time delay for the corresponding lane. The time delay in the traffic signal is set based on the density of vehicles on the roads Thus, that road will be given a green signal. Priorities are assigned in this manner and according to them the assigned roads will open. For emergency vehicle detection sound sensor is used at each lane to detect the sound of the siren so that such vehicles are given priority and they don’t need to wait. When siren sound is detected an emergency light is turned ON indicating the presence of emergency in that particular lane and along with emergency light, the control signal turns on the green light for that lane, turning all the signals of other lanes to be red providing an emergency override. The sound sensor is given a higher priority than the IR sensor.

Utility bills can be a significant expense for landlords, but there are ways to lower these costs. By making some simple changes, landlords can save money on their utility bills each month. 1. Educate Tenants About Energy Conservation One of the most effective ways is to educate tenants about energy conservation. By teaching tenants about simple things like turning off lights when they leave a room or setting their thermostats a few degrees lower in the winter, landlords can help their tenants save money on their monthly utility bills. 2. Install Low-Flow Fixtures Low-flow fixtures can be installed in a variety of locations, including toilets, showers, and faucets. By installing low-flow fixtures, landlords can help their tenants to save money on their water bills. Another way to lower utility costs is to make sure that the property is well-insulated. This will help to reduce the amount of heat that is lost through the walls and ceilings. 3. Educate Tenants About Water Conservation Water conservation is important for a number of reasons. First, it can help to reduce the strain on local water resources. In many areas of the country, water resources are already under stress due to population growth and climate change. By conserving water, landlords can help to reduce the demand on these resources. Second, water conservation can save landlords money. 4. Use Smart Thermostats Smart thermostats can be programmed to automatically adjust the temperature in a space based on the time of day and the occupants' needs. This can lead to significant savings on heating and cooling costs. Another way to lower utility costs is to make sure the building is well-insulated. This will help to keep the indoor temperature more consistent, which can reduce the need for heating and cooling. 5. Educate Tenants About Recycling Recycling can help to reduce the amount of waste that is sent to landfill sites, and it can also help to reduce the amount of energy that is required to process and dispose of waste. Another way in which landlords can lower utility costs is by encouraging tenants to use energy-efficient appliances and lighting. 6. Use LED Lighting LED lights are much more energy-efficient than traditional incandescent bulbs, and they also last much longer. This means that landlords can save money on both their energy bills and their maintenance costs. LED lights are available in a wide range of sizes, shapes, and colors, so landlords can find the perfect fit for their needs. They can also be used in a variety of settings, both indoors and outdoors. 7. Educate Tenants About Storm Water Runoff Storm water runoff is a major source of water pollution, so it is important for landlords to take measures to reduce it. There are a few things tenants can do to reduce storm water runoff: Use a rain barrel or cistern to collect rainwater for watering plants or washing cars. Direct downspouts away from the foundation of the house to reduce the amount of water that seeps into the basement or crawl space. 8. Use Energy Efficient Appliances There are many ways landlords can lower utility costs for their tenants. One way is to install energy efficient appliances. Energy efficient appliances use less electricity and water, which can lower utility bills. Another way to lower utility costs is to insulate the rental property. Insulation helps to keep the heat in during the winter and the cool air in during the summer. This can help to lower heating and cooling costs.

The system in the project works by taking input values from capacitor as a sensor. The capacitor is placed inside the tank and as the liquid level rises or decreases, the input values from the capacitor change. By calibrating according to user needs, we can set a LOW level, a MID level and a HIGH level. When the level reaches LOW or empty initially, the pump in the main tank will start up and the liquid will flow into the previous tank. User can give input using a switch to decide if he/she wants the tank to be half-full (MID). By default the pump will turn off once the level is HIGH. At some point if user wishes to turn this cycle off, there is a switch which can turn the entire system off. In case of system failure because of faulty components, if the liquid level goes above HIGH, a buzzer will go off as an alarm to the user. For better visual indication, a LED will give respective colors to indicate different levels. Red for LOW, Green for MID and Blue for HIGH. This system can work with any type of liquid as it works on the concept of dielectric medium.

Traffic signals are used to control the flow of vehicles. In the recent years, the need of transportation has gain immense importance for logistics as well as for common human. This has given rise to the number of vehicles on the road. Due to this reason, traffic jams and road accidents are a common sight in any busy city. Traffic Signals provide an easy, cheap, automatic and justified solution to the road points where the vehicles may turn to other directions e.g. roundabouts, culverts, busy walk through etc. The project we have chosen is an 4-way traffic controller. The basic idea behind the design is to avoid the collision of vehicles by providing appropriate signals to different directions for a limited time slot, after which the next waiting drivers will be given same treatment. In this way a cycle will be established which will control the traffic. The control signals are 3-lights. Top light is Red(Stop), Middle light is Yellow(Wait) Bottom light is Green(Go). We used 89C51 microcontroller for this operation. In this project, we connect 4 7-seg LED display at port 2 of microcontroller and these are controlled by port 0. At port 0 we use pull up transistor. Port 1 & Port 3 of microcontroller are used for signal indication.

In the late 1960s, computer vision began at universities which were pioneering artificial intelligence. It was meant to mimic the human visual system, as a stepping stone to endowing robots with intelligent behavior.[11] In 1966, it was believed that this could be achieved through a summer project, by attaching a camera to a computer and having it "describe what it saw".[12][13] What distinguished computer vision from the prevalent field of digital image processing at that time was a desire to extract three-dimensional structure from images with the goal of achieving full scene understanding. Studies in the 1970s formed the early foundations for many of the computer vision algorithms that exist today, including extraction of edges from images, labeling of lines, non-polyhedral and polyhedral modeling, representation of objects as interconnections of smaller structures, optical flow, and motion estimation.[11] The next decade saw studies based on more rigorous mathematical analysis and quantitative aspects of computer vision. These include the concept of scale-space, the inference of shape from various cues such as shading, texture and focus, and contour models known as snakes. Researchers also realized that many of these mathematical concepts could be treated within the same optimization framework as regularization and Markov random fields.[14] By the 1990s, some of the previous research topics became more active than the others. Research in projective 3-D reconstructions led to better understanding of camera calibration. With the advent of optimization methods for camera calibration, it was realized that a lot of the ideas were already explored in bundle adjustment theory from the field of photogrammetry. This led to methods for sparse 3-D reconstructions of scenes from multiple images. Progress was made on the dense stereo correspondence problem and further multi-view stereo techniques. At the same time, variations of graph cut were used to solve image segmentation. This decade also marked the first time statistical learning techniques were used in practice to recognize faces in images (see Eigenface). Toward the end of the 1990s, a significant change came about with the increased interaction between the fields of computer graphics and computer vision. This included image-based rendering, image morphing, view interpolation, panoramic image stitching and early light-field rendering.[11] Recent work has seen the resurgence of feature-based methods, used in conjunction with machine learning techniques and complex optimization frameworks.[15][16] The advancement of Deep Learning techniques has brought further life to the field of computer vision. The accuracy of deep learning algorithms on several benchmark computer vision data sets for tasks ranging from classification, segmentation and optical flow has surpassed prior methods.[citation needed]

Periodic volatility is healthy and good for the markets; it keeps the herd mentality in control Global currency shifts, a slow economic recovery and richer valuations have led to volatility in the Indian markets intermittently. Use these to build your corpus. For some time now, the Indian equity market has been on a batting wicket, scoring ever higher. These periods of batting excellence, though, have been scarred by dry spells. In other words, the market often witnessed volatility. There were many reasons behind this. Recently, the Reserve Bank of India’s neutral credit policy, with a hawkish tone, saw a immediate reaction in the stock market. As further rate cuts were expected, markets were disappointed. Stock market reactions to events such as this are turning commonplace. Currency movements and a stronger dollar are other factors that are driving greater volatility globally. Cross-currency movements—one currency getting stronger and another weaker—against the Indian rupee is also playing occasional havoc in the markets. Despite the fact that the Indian rupee is one of the better behaved currencies, helping toward robust fund flows, a strong dollar and possible interest rate tightening in the West in 2015 have also been responsible for the intermittent market volatility. Even the recent earnings season for Indian companies wasn’t as optimistic as expected. This quarter, the financial year 2015’s estimated earnings growth ended on a low note with consensus earnings growth estimates for BSE 100 companies dropping to 10.1%, down 600 basis points (bps) since the end of the last earnings season (as on 17 November 2014). One basis point is one-hundredth of a percentage point. Even though earnings have been showing signs of bottoming out, equity prices are a shade higher. Fortunately, valuations haven’t yet gone overboard; though they are not necessarily inexpensive. Nevertheless, because of the richer valuations, stocks are going through corrections The good in volatility The thing to remember is that periodic volatility is healthy and good for the markets; it keeps the herd mentality in control. It provides opportunities to investors who are on the look out for good entry points, which arise only during volatile times. That’s the beauty of the market. Investors can accumulate high quality assets on the decline as prospects for equity markets are rosy for the period 2016-2018. Over the next few years, the Indian economy is expected to bounce back from its slow-moving growth rates. While the new gross domestic product (GDP) figures look good (showing growth rates of 7.4%), the investment cycle is yet to pick up to the desired pace. But we are optimistic that the growth cycle will begin to increase sooner rather than later. In a few years, the Indian economy is poised to record some of the highest growth rates in the world. In the other big economy (China), growth rates are plateauing. The euro zone economy is struggling, while the rest of the world is much below peak level growth rates. The only country that is turning out decent growth numbers is the US—and that benefits India immensely. Deflation is clear in the global economy, especially in commodity prices such as oil and metals. With oil at $60-65 a barrel, Indian economy saves about $45 billion a year And if we get the supply chain right, interest rates could go down much more significantly. This would be very good for the capital expenditure cycle and the return on equity in the long run. Most Indian investors are still under-invested in equity. So, high volatility for any reason, whether global currency or supply of paper through equity issuances such as divestment or institutional placements, it’s an opportunity to pick up Indian equities for the long term. Corrections aren’t something that one should worry about if you are an Indian equity investor. In a unique position Purely from an investing point of view, the recent correction in technology stocks gave one the opportunity to invest in the sector with a three-year role. Among the cyclical sectors, the correction in commodities, too, provides an opportunity to invest with a three-year horizon. We all know that the stock market is not a one-way street that goes up all the time. But, unfortunately, most of us don’t act on it. Those who do are likely to reap significant rewards in the longer run. Investors who feel they have missed the bus can, and should, look forward to market corrections. It will, however, be a bumpy ride. That’s because though we have an economy that’s on the cusp of growth, concerns persist about large pockets of global economic trouble. But again, given that the growth dynamics in India have changed in the recent past with oil at $65 and further economic reforms on the anvil, Indian equities will deliver better returns than other investments. Therefore, whenever the market runs into rough weather, ensure that you use the opportunity to stuff some sound assets in your kitty. This article has also been published in Mint on 10th March 2015
