Pellucid Marginal Degeneration
Pellucid marginal degeneration (PMD) is a degenerative corneal condition, often confused with keratoconus. It typically presents with painless vision loss affecting both eyes. Rarely, it may cause acute vision loss with severe pain due to perforation of the cornea. It is typically characterized by a clear, bilateral thinning (ectasia) in the inferior and peripheral region of the cornea, although some cases affect only one eye. The cause of the disease remains unclear. Pellucid marginal degeneration is diagnosed by corneal topography. Corneal pachymetry may be useful in confirming the diagnosis. Treatment usually consists of vision correction with eyeglasses or contact lenses. Intacs implants, corneal collagen cross-linking, and corneal transplant surgery are additional options. Surgery is reserved for individuals who do not tolerate contact lenses. The term "pellucid marginal degeneration" was first coined in 1957 by the ophthalmologist Schalaeppi. The word "pellucid" means c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PMD 85
The PMD 85 is an 8-bit personal computer produced since 1985 by the companies Tesla Piešťany and Tesla Bratislava in the former Czechoslovakia. They were deployed ''en masse'' in schools throughout Slovakia (while the IQ 151 performed a similar role in the Czech part of the country). The first Czechoslovak video games were created on the PMD 85 (other platforms were ZX Spectrum and Atari). The production was local due to a lack of foreign currencies for purchasing systems from the West.{{Citation needed, date=May 2007 After the Velvet Revolution in 1989, the production was stopped. The PMD 85 was not competitive in quality or features compared to foreign PCs available at that time.

PMD (software)
PMD is an open source static source code analyzer that reports on issues found within application code. PMD includes built-in rule sets and supports the ability to write custom rules. PMD does not report compilation errors, as it only can process well-formed source files. Issues reported by PMD are rather inefficient code, or bad programming habits, which can reduce the performance and maintainability of the program if they accumulate. It can analyze files written in Java, JavaScript, Apex and Visualforce, PLSQL, Apache Velocity, XML, and XSL. While PMD does not officially stand for anything, several retroacronyms have been suggested, including for instance ''Programming Mistake Detector'' and ''Project Meets Deadline''. Features PMD is able to detect flaws or possible flaws in source code, like: * ''Possible bugs''—Empty try/catch/finally/switch blocks. * ''Dead code''—Unused local variables, parameters and private methods. * Empty if/while statements. * ''Overcomplicated ...

P-Menthane-3,8-diol
''p''-Menthane-3,8-diol, also known as ''para''-menthane-3,8-diol, PMD, or menthoglycol, is an organic compound classified as a diol and a terpenoid. It is colorless. Its name reflects the hydrocarbon backbone, which is that of ''p''-menthane. A total of eight stereoisomers are possible, based on the three stereocenters of the ring. Depending on the source, one or more may predominate. Use as insect repellent ''p''-Menthane-3,8-diol is the active ingredient in some insect repellents. Its odor and chemical structure are similar to menthol and has a cooling feel. Its repellent effect was discovered in the 1960s by the industry. There are eight possible stereoisomers of PMD; the exact composition is rarely specified and is commonly assumed to be a complex mixture. PMD is found in small quantities in the essential oil from the leaves of ''Corymbia citriodora'', formerly known as ''Eucalyptus citriodora''. This tree is native to Australia, but is now cultivated in many warm places ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polarization Mode Dispersion
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. Unless it is compensated, which is difficult, this ultimately limits the rate at which data can be transmitted over a fiber. Overview In an ideal optical fiber, the core has a perfectly circular cross-section. In this case, the fundamental mode has two orthogonal polarizations (orientations of the electric field) that travel at the same speed. The signal that is transmitted over the fiber is randomly polarized, i.e. a random superposition of these two polarizations, but that would not matter in an ideal fiber because the two polarizations would propagate identically (are degenerate). In a realistic fiber, however, there are random imperfections that break the circular symmetry, causing the two pola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmdale, California
Palmdale is a city in northern Los Angeles County in the U.S. state of California. The city lies in the Antelope Valley region of Southern California. The San Gabriel Mountains separate Palmdale from the Los Angeles Basin to the south. On August 24, 1962, Palmdale became the first city in the Antelope Valley. Forty-seven years later, in November 2009, voters approved making it a charter city. Palmdale's population was 169,450 at the 2020 census, up from 152,750 at the 2010 census. Palmdale is the 32nd most populous city in California. Together with its immediate northern neighbor, the city of Lancaster, the Palmdale/Lancaster urban area had an estimated population of 513,547 as of 2013.

Photonic Mixer Device
A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for Distance measurement, measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED. Laser-based time-of-flight cameras are part of a broader class of scannerless LIDAR, in which the entire scene is captured with each laser pulse, as opposed to point-by-point with a laser beam such as in scanning LIDAR systems. Time-of-flight camera products for civil applications began to emerge around 2000, as the semiconductor processes allowed the production of components fast enough for such devices. The systems cover ranges of a few centimeters up to several kilometers. Types of devices Several different technologies for time-of-flight cameras have been developed.

Personal Transporter
A personal transporter (also powered transporter, electric rideable, personal light electric vehicle, personal mobility device, etc.) is any of a class of compact, mostly recent (21st century), motorised micromobility vehicle for transporting an individual at speeds that do not normally exceed . They include electric skateboards, kick scooters, self-balancing unicycles and Segways, as well as gasoline-fueled motorised scooters or skateboards, typically using two-stroke engines of less than displacement. Many newer versions use recent advances in vehicle battery and motor-control technologies. They are growing in popularity, and legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation. Generally excluded from this legal category are electric bicycles (that are considered to be a type of bicycle); electric motorbikes and scooters (that are treated as a type of motorcycle or moped); and p ...
