Model no: 6A The project is based on the principle of firing angle delay of thyristors using back to back SCR’s in series with the load with control being fed from a microcontroller via opto isolators. The firing angle would be adjusted to maintain the load power by rising and decreasing slowly the intensity of the lamp load, resembling the situation of a flasher for aviation obstruction light used in tall buildings. The above operation can also be carried out by using a TRIAC in series with the load.
The project is having comparator which is used for ZVR output. The ZVR is given as reference interrupt to microcontroller. The microcontroller is of 8051 family which is of 8bit. In this we are using switch which is used for increasing the firing angle. The optisolator used in the project is used as switching element using this we will trigger the back to back SCR. On the base of SCR triggering the intensity of the AC lamp can be controlled.
The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

O.K. this John Carter movie looks sorta like a Star Wars rip-off. Why should I spend my money to go see a retread? I’m Keith Kelly. Stick around, and I’ll let you know why “John Carter” is worth a trip to theatre.
I’m going to confess right up front that I’ve been a fan of John Carter of Mars for over 40 years. The original novel was written way back in 1911, by Edgar Rice Burroughs, whom some of you may know by his more famous creation-Tarzan of the Apes.
I instantly fell in love with the swashbuckling adventures of Mr. Carter, his princess Deja Thoris, the landscapes of a dying planet Mars, the 4-armed 15 foot tall Tharks, and all the other great bits of imagination that soaked every page.
The film has been in development hell since the 1930’s-first as an animated version, then with stop-motion, then with an ever-increasing list of filmmakers trying to get a handle on the sweeping story. Its influences have been seen in everything from Flash Gordon, to Superman, to Star Wars and Avatar. George Lucas especially borrowed heavily from the series. Maybe “borrowed” is too nice a word.
So Walt Disney finally bankrolled Director Andrew Stanton-the guy who brought Wall-E to life, and the end result is the $250 million “John Carter”. I guess they figured naming the film with its original title “A Princess of Mars” might have seemed a bit too wimpy.
The end result is a pretty decent movie that the trailers don’t do justice. Not totally spectacular, but a good, solid action-adventure space opera fitting for most members of the family. It’s not slavish to the book-which is not a bad thing since literary and movie tastes have changed a lot in the past hundred years. It does hold true to all the important aspects of the novel. Fighting man John Carter gets transported to a dying planet-Mars, or “Barsoom” as the natives call it. Because of the difference in gravity, he finds he is stronger, faster, and can leap tall buildings in a single bound. He first meets the savage Tharks, and their noble leader, or “Jeddak”-Tars Tarkas. We follow his adventures as he slowly steps into the role he is destined for-Savior of the planet Barsoom, and as he falls in love with Dejah Thoris.
This film is an exotic adventure, with great visuals, realistic and emotive alien creatures, stirring action and even a little romance. It does get a little too “talky” at times, slowing down the pace too much, and it takes awhile to get to the full-out action scenes, but it’s all worth it in the end.
Taylor Kitsch was not what I had originally envisioned as John Carter, but he won me over with his quiet brooding charm and a touch of humor-he wasn’t just a hunk with lots of muscles. Lynn Collins makes a luminous modern princess-smart, self-reliant with the ability to kick-ass. Mark Strong is slimy and powerful as the villain Matai Shang. I would have liked some more screen time for Willem Dafoe’s excellent Tars Tarkas, to see a little more of the building friendship that was in the book, but maybe we’ll see more of that in a sequel-if the box office demands one.
I give John Carter, directed by Andrew Stanton, a grade of “B”. I’m Keith Kelly.

Cell phone base stations may be free standing towers or mounted on existing structures, such as trees, water tanks, or tall buildings. The antennas need to be located high enough so they can adequately cover the area. Base stations usually range in height from 50-200 feet.
Cell phones communicate with nearby cell towers mainly through radiofrequency (RF) waves, a form of energy in the electromagnetic spectrum between FM radio waves and microwaves. Like FM radio waves, microwaves, visible light, and heat, they are forms of non-ionizing radiation. This means they cannot cause cancer by directly damaging DNA. RF waves are different from stronger types of radiation such as x-rays, gamma rays, and ultraviolet (UV) light, which can break the chemical bonds in DNA.
At very high levels, RF waves can heat up body tissues. (This is the basis for how microwave ovens work.) But the levels of energy used by cell phones and towers are much lower.
When a person makes a cell phone call, a signal is sent from the phone's antenna to the nearest base station antenna. The base station responds to this signal by assigning it an available radiofrequency channel. RF waves transfer the voice information to the base station. The voice signals are then sent to a switching center, which transfers the call to its destination. Voice signals are then relayed back and forth during the call.
KONE, an innovative leader in the elevator and escalator industry, today announced a new high-rise elevator technology that is set to break industry limits and enable future elevator travel heights of 1 kilometer – twice the distance currently feasible. The KONE UltraRope™ is a completely new hoisting technology that eliminates the disadvantages of conventional steel rope and opens up a world of possibilities in high-rise building design – an important consideration as urbanization brings increasing numbers of people to cities.
Comprised of a carbon fiber core and a unique high-friction coating, KONE UltraRope is extremely light, meaning elevator energy consumption in high-rise buildings can be cut significantly. The drop in rope weight means a dramatic reduction in elevator moving masses – the weight of everything that moves when an elevator travels up or down, including the hoisting ropes, compensating ropes, counterweight, elevator car, and passenger load (see image). Due to the significant impact of ropes on the overall weight of elevator moving masses, the benefits of KONE UltraRope increase exponentially as travel distance grows.
KONE UltraRope is extremely strong and highly resistant to wear and abrasion. Elevator downtime caused by building sway is also reduced as carbon fiber resonates at a completely different frequency to steel and most other building materials. KONE UltraRope has an exceptionally long lifetime – at least twice that of conventional steel rope – and thanks to the special coating, no lubrication is required in maintaining it, enabling further cuts in environmental impact.
All of this adds up to unprecedented eco-efficiency, durability and reliability in future high-rise elevator travel.
“We are proud to introduce this innovation that we are certain will revolutionize the elevator industry for the tallest segment of buildings across the globe. The benefits of KONE UltraRope versus conventional elevator hoisting technologies are numerous and indisputable,” said KONE President and CEO Matti Alahuhta.
KONE UltraRope has been developed and tested rigorously both in real elevators and simulation laboratories at KONE’s research and development facilities in Finland. Since 2010, it has been tested in operation at the world’s tallest elevator testing laboratory,
KONE’s Tytyri facility built over 300 meters underground adjacent to an active limestone mine. Properties like tensile strength, bending lifetime, and material aging are just some of the qualities that have been measured.
Urbanization is a key driver for the development of cities and the elevator industry. More than half of the world’s population already live in urban areas, and the United Nations estimates that by 2050 seven out of every 10 people on the planet will be living in cities. Building upwards is seen as the sustainable urban solution, and the number of tall buildings built around the globe has increased rapidly in recent years. Increasingly, tall buildings are also growing taller. Nearly 600 buildings of 200 meters or more are currently under construction or planned to be built over the next few years, according to the Council on Tall Buildings and Urban Habitat. While there are currently three buildings in the world that top the 500-meter mark, there are plans for 20 more such buildings to be built in coming years. Additionally, there are currently some 3,000 buildings in the world that could benefit from modernization with KONE UltraRope.
It took over 47 fire engines and almost 200 firefighters to extinguish this massive fire. The tall building was seen blazing in fire at midnight.
The strong force of nature is unmeasurable until you see it in action. This big tall building was nothing but a child's play for the force know as a flood.
Are you fed up of your life in the city? Have you started hating the noise of the streets and the honks of the vehicles? Are you bored of watching the same old tall building from your window every day? The time has come for you to step out of your mini galaxy of the city and explore some real earth. Welcome to the country place resort. We are listed among the best NY upstate vacation destinations. We have a queue of various kinds of different fun activities and a lot more to explore.
