Optical Wireless Communications
Optical wireless communications (OWC) is a form of optical communication in which unguided light is used "in the air" (or in outer space), without an optical fiber. Visible, infrared (IR), or ultraviolet (UV) light is used to carry a wireless signal. It is generally used in short-range communication; extensions exist for long-range and ultra-long range. OWC systems operating in the visible band (390–750 nm) are commonly referred to as visible light communication (VLC). VLC systems take advantage of light-emitting diodes (LEDs) which can be pulsed at very high speeds without a noticeable effect on the lighting output and human eye. VLC can be possibly used in a wide range of applications including wireless local area networks, wireless personal area networks and vehicular networks, among others. On the other hand, terrestrial point-to-point OWC systems, also known as the free space optical (FSO) systems, operate at the near IR frequencies (750–1600 nm). These sy ...

Radio Over Fiber
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Access Networks
Hybrid Access Networks refer to a special architecture for broadband access networks where two different network technologies are combined to improve bandwidth. A frequent motivation for such Hybrid Access Networks to combine one xDSL network with a wireless network such as LTE. The technology is generic and can be applied to combine different types of access networks such as DOCSIS, WiMAX, 5G or satellite networks. The Broadband Forum has specified an architecture as a framework for the deployment of such converged networks. Use cases One of the main motivations for such Hybrid Access Networks is to provide faster Internet services in rural areas where it is not always cost-effective to deploy faster xDSL technologies such as G.Fast or VDSL2 that cannot cover long distances between the street cabinet and the home. Several governments, notably in Europe, required network operators to provide fast Internet services to all inhabitants with a minimum of 30 Mbps by 2020. A second use ...

Augmented Reality
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D computer graphics, 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersion (virtual reality), immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory Modality (human–computer interaction), modalities, including Hearing, auditory, haptic perception, haptic, and Somatosensory system, somatosensory. The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, ...

University Of Melbourne
The University of Melbourne (colloquially known as Melbourne University) is a public university, public research university located in Melbourne, Australia. Founded in 1853, it is Australia's second oldest university and the oldest in the state of Victoria (Australia), Victoria. Its Parkville Campus (University of Melbourne), main campus is located in Parkville, Victoria, Parkville, an inner suburb north of Melbourne central business district, Melbourne's central business district, with several other campuses located across the state of Victoria (Australia), Victoria. Incorporated in the 19th century by the State of Victoria, colony of Victoria, the University of Melbourne is one of Australia's six sandstone universities and a member of the Group of Eight (Australian universities), Group of Eight, Universitas 21, Washington University in St. Louis, Washington University's McDonnell International Scholars Academy, and the Association of Pacific Rim Universities.

Australian Research Council
The Australian Research Council (ARC) is the primary non-medical research funding agency of the Australian Government, distributing more than in grants each year. The Council was established by the ''Australian Research Council Act 2001'', and provides competitive Funding of science, research funding to academics and researchers at Australian universities. Most health and medical research in Australia is funded by the more specialised National Health and Medical Research Council (NHMRC), which operates under a separate budget. ARC does not directly fund researchers, but however allocates funds to individual schemes with specialised scopes, such as Discover (fundamental and empirical research) and Linkage (domestic and international collaborative projects). Most of these schemes fall under the National Competitive Grants Program (NCGP), whereby institutions must compete amongst each other for funding. ARC also administers the Excellence in Research for Australia, Excellence i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optica Fellow
The Optica Fellow is a membership designation of Optica (formerly known as The Optical Society (OSA)) that denotes distinguished scientific accomplishment. The bylaws of this society only allow 10% of its membership to be designated as an Optica Fellow. The Optica Fellow requires peer group nomination. The nominee An Optica member can only become an Optica Fellow when nominated by a peer group of other current Optica Fellows. Review of the nomination is then passed to the Optica Fellow Members Committee. This committee then nominates the candidate to the Board of Directors on an annual basis. Finally, the purpose of this award is to designate a member as one who has "made significant contributions to the advancement of optics". The process The process includes actively identifying possible candidates who might qualify for this award. Contributing factors for qualification are diverse within the optics community. These factors include significant or distinguishing scientific a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Missing (living People)
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
