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.

Basic of wireless communication, explains with the generation by generation developments and improvements in the technology.

•Unlike Fourier transform, whose basis functions are sinusoids, wavelet transforms are based on small waves, called wavelets, of limited duration.
•Fourier transform provides only frequency information, but wavelet transform provides time-frequency information.
•Wavelets lead to a multiresolution analysis of signals.
•Multiresolution analysis: representation of a signal (e.g., an images) in more than one resolution/scale.
•Features that might go undetected at one resolution may be easy to spot in another.
