List Of Seminar Topics For Computer Science Page - 3
E Paper
E-paper (sometimes called radio paper or just electronic paper) is a portable, reusable storage and display medium that looks like paper but can be repeatedly written on (refreshed) - by electronic means - thousands or millions of times. E-paper will be used for applications such as e-books, electronic newspapers, portable signs, and foldable, rollable displays. Information to be displayed is downloaded through a connection to a computer or a cell phone, or created with mechanical tools such as an electronic "pencil". An e-paper display actually uses no power when the image is not changing.
Smart Fabrics
The term “Smart Fabrics” refers to a broad and somewhat ill-defined field of study and products that extend the functionality and usefulness of fabrics. Humanity has used various types of fabrics for thousands of years to keep warm, provide comfort, and protect from the elements of nature. For most of recorded history, fabrics have also provided a means of self-expression through colors, patterns, cuts, and other stylistic elements. The basic technological elements of smart fabric are conductive or semiconductive threads and yarns, nanoelectronics applied directly to fibers, yarns, or woven elements, and chemical treatments that provide different features.smart fabrics are designed to maximise characteristics such as lightness, breathability, waterproofing etc, or to react to heat or light. They are usually manufactured using microfibres.
Intel Santa Rosa
As with all Centrino platforms, Santa Rosa is the codename given to a combination of Intel components: CPU, chipset and wireless Ethernet. With Santa Rosa there's a new optional fourth component, now called Intel Turbo Memory but at one point it was known as Robson. The Santa Rosa CPU is the same 65nm Merom based Core 2 Duo processor that was introduced last year with a few minor changes. The most noticeable change is that Santa Rosa CPUs can support up to an 800MHz FSB, up from 667MHz. The Core 2 Duo is a data hungry CPU, and thus giving it a faster FSB should improve overall performance when plugged in. A faster FSB is also necessary as Intel increases clock speeds; the faster your CPU runs, the faster it needs data to work on in order to operate efficiently.
Optical Computers
An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared ( IR ) beams,rather than electric current, to perform digital computations. An electric current flows at only about 10 percent of the speed of light. This limits the rate at which data can be exchanged over long distances, and is one of the factors that led to the evolution of optical fiber .The computers we use today use transistors and semiconductors to control electricity. Computers of the future may utilize crystals and metamaterials to control light. Optical computers make use of light particles called photons.
Plasmonics
Plasmonics is the study of the interaction between electromagnetic field and free electrons in a metal. Free electrons in the metal can be excited by the electric component of light to have collective oscillations. However, due to the Ohmic loss and electron-core interactions, loss are inevitable for the plasmon oscillation, which is usually detrimental to most plasmonic devices. Meanwhile, the absorption of light can be enhanced greatly in the metal by proper designing metal patterns for SP excitation. Plasmonics takes advantage of the coupling of light to charges like electrons in metals, and allows breaking the diffraction limit for the localization of light into subwavelength dimensions enabling strong field enhancements.
Wireless USB
Wireless USB (WUSB) is a form of Universal Serial Bus ( USB ) technology that uses radio-frequency ( RF ) links rather than cables to provide the interfaces between a computer and peripherals, such as monitors, printers, external drives, head sets, MP3 players and digital cameras. The WUSB technology is based on the WiMedia ultra wideband common radio platform. An advantage of using a wireless USB is the ability to sync to a multiple media devices. The disadvantages to using a wireless USB is the device may run slower than normal, there is a risk of damage because of the USB is sticking out of the computer, and there is a greater risk of having information hacked.
Ajax (Asynchronous JavaScript and XML)
AJAX is not a new programming language, but a new way to use existing standards. AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page. AJAX is a new technique for creating better, faster, and more interactive web applications with the help of XML, HTML, CSS, and Java Script. Ajax uses XHTML for content, CSS for presentation, along with Document Object Model and JavaScript for dynamic content display. Ajax is a client-side script that communicates to and from a server/database without the need for apostback or a complete page refresh.
ZigBee is the wireless language that everyday devices use to connect to one another. ZigBee is designed for wireless Automation and other lower data tasks, such assmart home automation and remote monitoring. ZigBee is a low-cost, low-power,wireless mesh networking standard. The low cost allows the technology to be widelydeployed in wireless control and monitoring applications, the low power usage allowslonger life with smaller batteries, and the mesh networking provides high reliability andlarger range. Due to the low-cost and low-power usage this wireless technology is widelyused in Home Automation, Smart Energy, Telecommunication Applications, PersonalHome, Hospital Care. ZigBee enables new opportunities for wireless sensors and controlnetworks. ZigBee is standard based,low cost, can be used globally, reliable and self healing, supports large number of nodes, easy to deploy ,very long battery life and secure.
Polymer Memory
Polymer memory refers to memory technologies based on the use of organic polymers. Some of these technologies use changes in the resistance of conducting polymers under read/write control. Other architectures are based on ferroelectric polymers. The properties of polymer memory are low-cost and high-performance, and have the potential for 3D stacking and mechanical flexibility. Variants can be write-once or multiple-write. Printed versions of this technology already exist and are used in low-density applications such as toys.
Bio - Computer
BIO computer use system of biologically derived molecules such as DNA and protein to perform computational caculations, retreiving and processing data. Biocomputing is one of the upcoming field in the areas of mole-cularelectronics and nanotechnology. The idea behind blending biology with technology is due to the limitations faced by the semiconductor designers in decreasing the size of the silicon chips, which directly affects the processor speed. Biocomputers consists of biochips unlike the normal computers, which are silicon-based computers. This biochip consists of biomaterial such as nucleic acid, enzymes, etc.
