Title: Repeater less branch powered fiber optic communication.
Departments: Communication, Electronics and electrical, Telecommunication.
Can be used for: Paper presentation and related study.

This is a project that falls under the subject of "FIber optics communication". this papers idea was invented by Lars Erik Eskildsen, Evan Lee Goldstein, Per Bang Hansen. The basics of this paper presentation can be stated in this manner. The title suggests that the engineering project in the fiber optics is to design a network with branches that is repeater less. This idea is to construct a fiber network, configured in the ring topology with number of hubs in the network and one or more branching its interconnected in that. the branching units are designed to add/drop the signals along the path of the network. The engineering projects on fiber optics is to reduce the loss and remove the repeaters still make that network effective with the optical amplifiers.

Sample of this fiber optics project: The specification relates to a repeaterless branch powered fiber optic communications system. The system comprises an optical fiber cable trunk, configured in ring topology, with one or more telecommunications hub, and one or more branching unit serially interconnected therein. Branching units are provided as convenient add/drop points along the extend to cable stations. Cable stations insert and extract telecommunications traffic from the trunk ring over the branch fiber optic cables. In addition, the branch fiber optic cables are also coupled to light emitting power sources. The branch fiber optic cables deliver the energy produced from these power sources to optical amplifiers serially embedded within the branch fiber optic cables, the branching units, or the optical fiber cable trunks. The optical amplifiers convert the energy delivered from the branch fiber optic cables into amplified telecommunications signals. Thus, remote pumping or energy delivery is achieved without the requirement of additional optical fiber cable runs and further, using solely passive repeaterless components.

Title: Interactive wireless vehicle security system.
Department: Electronics and communication, Automobile, Networking, computers, security.
Can be used for: Paper presentations, final year projects, research work for students and others.

This projects idea was an inspiration from this paper by Wang Qiahe et al. This paper by him is on the security system for the vehicles via wireless communication. This is one of the projects that most of the young engineers get attracted. This attraction is due to the various number of fields this project cover. subjects like networking, communication, embedded, automobiles and more. This is such an interesting project to work on. The simple working of this projects idea can be stated as following, This has an security system designed that detects intrusive activities in and around a vehicle and transmits the message (warning message). the speciality about this project is that, it also adds specific description of the warning in the same message through a wireless telephone network to the administrator or the owner's assigned contact. So that in response that message the admin or the contact will be able to establish a remote wireless communication with the security system and get further information.
Sample of this paper presentation / engineering project: The CPU can also be programmed to take other actions automatically, through the GSM module and/or the vehicle control interface, in response to specific intrusion indicators. For example, in response to intrusion sensors indicating vehicle vibration or movement in the vehicle's vicinity, the CPU can send a command through the vehicle control interface to lock the doors and sound the vehicle's horn or alarm siren. If one of the intrusion sensors indicates that the vehicle has been tilted, on the other hand, the CPU can be programmed to select from the message ROM the message that the vehicle is being towed away by a thief and to transmit that message through the communication interface to the GSM module, with direction that it be sent to police and emergency telephone numbers. And in response to a pressure reading from the gas pedal sensor, the CPU can be programmed to send a command through the vehicle control interface to disable the fuel pump so that fuel will stop flowing to the engine.

When the owner receives a message from the base unit specifying the type of intrusion and time of occurrence, he or she can initiate a number of responsive actions from the keypad, from a remote telephone, or, if supported by the local GSM service provider, from a computer or PDA. When the owner contacts the base unit through the GSM module, he or she can access the CPU by entering a pre-programmed password. Password authentication causes the CPU to access the menu ROM containing a series of digital voice instructions and menu prompts eliciting alternate choices. The menu prompts begin with the most general main menu level and progress to more specific sub-menus based on the owner's responses. The menu prompts are transmitted through the communication interface to the GSM module and from there to the owner.

This post on the great, Steve Jobs! is an tribute to the king of modern computers..
Everybody knows Steve Jobs was a genius, but only some of them knew his actual influence on present technology, one such person is Walt Mossberg who was the editor for the technical column in “wall street journal”. Walt Mossberg shares his thoughts about Steve Jobs in his blog shortly after his death.
Steve Jobs influenced billion of lives with his technology he has been role model to many of the present corporate leaders. Many people look upon him in the range of Thomas Alva Edison or Hendry ford.
He was the ultimate CEO, he hired many minds around the world, employed them for a long period of time, took many risks, made big bets and insisted on product quality unlike others. He empowered his users and not the intermediate corporate or it directories, which made him distinct and special from others.
Steve Jobs relationship with Walt Mossberg was cordial and highly professional. Since Walt was a product reviewer Steve Jobs discussed about his products with him over the phone, there are some instances that Mossberg would like to share with us,

THE PHONE CALLS:
Initially when Steve Jobs were at Apple Walt Mossberg didn’t know him. The first meeting between both took place only during Jobs return in 1977. Right after that time Jobs began to call him regularly during Sunday nights, to discuss about his reviews on his products which Walt Mossberg didn’t recommend for his readers .The talks between the both extended even for hours together. Now Walt Mossberg started to recommend apple products to an average non technical user which was Steve Jobs target.

THE PRODUCT UNVEILING:
 Sometimes Steve Jobs showed his new products first to Walt Mossberg in his boardroom before showing it to the world. He mostly did the same with the other journalists also. He was almost like a show man casting his products to others with immense pride in his voice. When Steve showed his first iPods to Walt Mossberg, Walt was quiet astonished and had asked Steve that how could a computer company produce an mp3 player but Steve had replied that Apple was not a computer company but it was a digital products company. It was the same with iTunes, iphone and even iPod. Steve had shown his first iphone to Mossberg at his house because he was too ill to go to office at that time.

THE SLIDES:
One technical conference that Steve Jobs always attended was D:ALL THINGS DIGITAL conference of Walt Mossberg’s news paper, where there is a principle of not using slides for any presentation ironically Steve’s prime presentation tool was slides. Once in the same conference Steve had prepared several slides for his speech (knowing that slides were not allowed) and was practicing them backstage before the program was about to begin. When Walt had insisted him not to use them on stage Steve argued with him for a very long time and then accepted not to use the slides on stage, yet he made it big that day and proved that he was the favorite speaker of people.

ICE WATER IN HELL:
Everyone knows about the relationship between Bill Gates and Steve Jobs. During the 5th D: conference, both Bill Gates and Steve Jobs had accepted to do a joint stage interview with Walt Mossberg. The interview started off first with Steve Jobs so that Bill Gates could join them later, in that interview Mossberg had asked Steve Jobs that “how it is like to see many windows users making use of your iTunes players?” for that Steve had replied that it is like “giving a glass of ice water to someone in hell”. Later when Bill Gates arrived he happened to hear about this comment, he asked Steve Jobs that:”so I guess I’m the representative from hell”, Steve Jobs merely handed Gates a cold bottle of water that he was carrying. The tension created by Bill Gates was simply shattered, the interview became a triumph and the audience gave a standing ovation at the end.

OPTIMIST:
Steve jobs was very optimistic this was shown very well during the dark days of apple in 1997 and 1998 when he was forced to turn to Microsoft for help. He still had his nasty and mercurial qualities which he later expressed to vendors and dealers who wanted to connect to Apple. He was a very self motivated person who still wanted to keep going even after his illness and liver transplant. Steve jobs was a great man who almost changed the view of technology to a common man.



Michelle and I are saddened to learn of the passing of Steve Jobs. Steve was among the greatest of American innovators - brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it.
"By building one of the planet's most successful companies from his garage, he exemplified the spirit of American ingenuity. By making computers personal and putting the internet in our pockets, he made the information revolution not only accessible, but intuitive and fun.
"And by turning his talents to storytelling, he has brought joy to millions of children and grownups alike. Steve was fond of saying that he lived every day like it was his last.
"Because he did, he transformed our lives, redefined entire industries, and achieved one of the rarest feats in human history: he changed the way each of us sees the world.
"The world has lost a visionary. And there may be no greater tribute to Steve's success than the fact that much of the world learned of his passing on a device he invented. Michelle and I send our thoughts and prayers to Steve's wife Laurene, his family, and all those who loved him."
—U.S. President Barack Obama and First Lady Michelle Obama

"Melinda and I extend our sincere condolences to Steve Jobs' family and friends. The world rarely sees someone who made such a profound impact."
—Bill Gates, Co-Founder and Chairman of Microsoft, and Melinda Gates

"Today the world lost a visionary leader, the technology industry lost an iconic legend and I lost a friend and fellow founder. The legacy of Steve Jobs will be remembered for generations to come."
—Michael Dell, CEO of Dell

—Jerry Brown, Governor of California

"Steve lived the California Dream every day of his life and he changed the world and inspired all of us."
—Arnold Schwarzenegger, Actor and Former Governor of California

We've lost a unique tech pioneer and auteur who knew how to make amazingly great products. Steve fought a long battle against tough odds in a very brave way. He kept doing amazing things in the face of all that adversity. As someone who has had his own medical challenges, I couldn't help but be encouraged by how he persevered."
—Paul Allen, Co-Founder of Microsoft

I want to express my deepest condolences at the passing of Steve Jobs, one of the founders of our industry and a true visionary. My heart goes out to his family, everyone at Apple, and everyone who has been touched by his work."

He was a great man with incredible achievements and amazing brilliance. He always seemed to be able to say in very few words what you actually should have been thinking before you thought it. His focus on the user experience above all else has always been an inspiration to me."
—Larry Page, CEO of Google

"Steve, thank you for being a mentor and a friend. Thanks for showing that what you build can change the world. I will miss you."
—Mark Zuckerberg, Founder and CEO of Facebook

"Once in a rare while, somebody comes along who doesn't just raise the bar, they create an entirely new standard of measurement."
—Dick Costolo, CEO of Twitter


RIP Steve! You lived the most meaningful life on the earth! We'll miss you..

We live in a generation where we witness the procession of contraptions that make our life easier by the day. Thanks to the brains behind such fabulous inventions. These gadgets play an influential role in leading a comfortable life.
One such soon-to-be, life-changing tool is the quantum computer which is being developed in the hope of matching up to the existing counterpart with the help of quantum particles rather than the transistors that the latter uses. Though the quantum computer is under development for more than two decades, the physicists are yet to attain a remarkable result except for the latest creation of a tiny "electron superhighway" that could one day be useful for building a successful quantum computer. In a recent paper in Physical Review Letters, Rice physicists Rui-Rui Du and Ivan Knez describe a new method for making a tiny device called a "quantum spin Hall topological insulator." The device, which acts as an electron superhighway, is one of the building blocks needed to create quantum particles that store and manipulate data. Today's computers use binary bits of data that are either ones or zeros whereas the quantum computers use quantum bits, or "qubits," which can be both ones and zeros at the same time. This quirk gives quantum computers a huge edge in performing particular types of calculations, said Du, professor of physics and astronomy at Rice University,Houston. For example, intense computing tasks like code-breaking, climate modeling and biomedical simulation could be completed thousands of times faster with quantum computers. "In principle, we don't need many qubits to create a powerful computer," he said. "In terms of information density, a silicon microprocessor with 1 billion transistors would be roughly equal to a quantum processor with 30 qubits". They are confident that the information encoded into these qubits is not likely to get lost over time due to quantum fluctuations which is called as fault tolerance. Du and Knez follow "topological quantum computing". Topological designs are expected to be more fault-tolerant than other types of quantum computers.
The topological designs led to the yet-to-be-discovered Majorana fermions, a stable pair of quantum particle that have a virtually immutable shared identity. Physicists believe the particles can be made by marrying a two-dimensional topological insulator to a superconductor. if a small square of a topological insulator is attached to a superconductor, Knez said, “The elusive Majorana fermions are expected to appear precisely where the materials meet. If this proves true, the devices could potentially be used to generate qubits for quantum computing”, he said.
Knez spent more than a year refining the techniques to create Rice's topological insulator. The device is made from a commercial-grade semiconductor that's commonly used in making night-vision goggles. Du said it is the first 2-D topological insulator made from a material that physicists already know how to attach to a superconductor.
"We are well-positioned for the next step," Du said. "Meanwhile, only experiments can tell whether we can find Majorana fermions and whether they are good candidates for creating stable qubits”. This quantum computer is sure to make a mark in the field of computing. So let us keep our fingers crossed and hopefully encounter a worth-a-wait device in the years to come.
