Characteristics, английский
- The distinguishing qualities of a navigation aid or buoy, including shape and color, whether fixed or flashing, and flashing sequence.
- A high-performance fiber with high chemical resistance that does not burn in air. it has no melting point and does not drip when exposed to flame. the fiber and fabrics from pbi retain their flexibility, dimensional stability, and significant strength without embrittlement even when exposed to flame or extreme heat. the fiber emits little smoke in extreme conditions. it processes well on conventional textile equipment, having processing characteristics similar to polyester. it can be used in 100% form or blended with other fibers. it has a high moisture regain and low modulus with comfort properties similar to cotton. the natural color of pbi is a gold-khaki shade, but it can be dyed to almost any medium to dark shade with conventional basic dyes.
- Acetate fabrics are in appearance fast-drying, wrinkle and shrinkage resistant, crisp or soft in hand depending upon the end use.
- Although modacrylics are similar to acrylics in properties and application, certain important differences exist. modacrylics have superior resistance to chemicals and combustion, but they are more heat sensitive (lower safe ironing temperature) and have a higher specific gravity (less cover).
- Although the properties of the nylons described above vary in some respects, they all exhibit excellent strength, flexibility, toughness, elasticity, abrasion resistance, washability, ease of drying, and resistance to attack by insects and microorganisms.
- Because acrylic fibers are thermoplastic, fabrics may be heat-set for wrinkle resistance and to provide permanency to pleats. acrylic fabrics have low moisture absorbency and dry relatively quickly. in general, acrylic fibers are resistant to the degrading effects of ultraviolet rays in sunlight and to a wide range of chemicals and fumes. they provide warmth in fabrics that are lightweight, soft, and resilient. acrylic fibers have relatively poor flame resistance compared with other fibers. some acrylic fabrics, particularly knit types, approximate the hand of fine wool. because of the composition and cross section of the fiber, fabrics made therefrom have a high bulk to weight ratio. this is further enhanced with the so-called “high bulk” spun yarns.
- Glass fiber is incombustible and will tolerate heat up to 1000°f without material damage. potential strength is not realized in woven fabrics or even in yarns, because the fiber is brittle and fracture points may develop, but nevertheless, very high tensile strength is obtained in woven fabrics, and is retained at elevated temperatures. the fiber originally was difficult to color but methods have been developed to accomplish this. moisture absorption is low. electrical and insulation resistance is high.
- Polychlal fibers have a soft, lamb’s wool-like hand and moderate moisture regain. the fibers are also characterized by high flame resistance and high abrasion resistance.
- Polyester fibers have high strength and are resistant to shrinking and stretching. fabrics are quick drying and tend to have wrinkle resistance and crease retention, wet and dry. polyester is used alone and in blends. it has been one of the first fibers to be developed in fabrics with durable-press features.
- Polyethylene fibers have a low specific gravity, extremely low moisture regain, the same tensile strength wet and dry, and are resistant to attack by mildew and insects. these qualities have made polyethylene fiber suitable for industrial applications, geotextiles, outdoor furniture, and similar applications. polyethylene fiber does not dye, and in most cases, it is colored by the addition of pigments and dyes to the material prior to spinning. it has a low melting point, a property that has restricted its use in apparel.
- Polypropylene fibers have a number of advantages over polyethylene fibers in the field of textile applications. the degree of crystallinity, 72 to 75%, results in a fiber that is strong and resilient, and does not fibrillate like high-density polyethylene. polypropylene has a high work of rupture, which indicates a tough fiber, and may be made with tenacities as high as 8.0 to 8.5 grams per denier. the melting point of polypropylene is 165°c, which is low by comparison with nylon or polyester, but is high enough to make it suitable for most textile applications. so light that it actually floats, polypropylene fiber provides greater coverage per pound than any other fiber. it is highly resistant to mechanical abuse and chemical attack.
- Rayon yarns are made in a wide range of types in regard to size, physical characteristics, strength, elongation, luster, handle, suppleness, etc. they may be white or solution dyed. strength is regulated by the process itself and the structure of the yarn. (also see polynosic fiber.) luster is reduced by including delustering materials, such as titanium dioxide pigments, in the fiber when it is extruded. the suppleness of the yarn is controlled by the number of filaments in the yarn, the denier or gauge of the individual filaments or fibers, and the fiber cross-section.
- Spandex is lighter in weight, more durable, and more supple than conventional elastic threads and has between two and three times their restraining power. spandex is extruded in a multiplicity of fine filaments which immediately form a monofilament. it can be repeatedly stretched over 500% without breaking and still recover instantly to its original length. it does not suffer deterioration from oxidation as is the case with fine sizes of rubber thread, and it is not damaged by body oils, perspiration, lotions, or detergents.
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a
Resolution, английский
- The smallest change in the parameter being measured that causes a detectable change in the output of the instrument.
- Разрешение
- Defines the smallest resolvable object in the target plane at a given range-to-target, atmospheric condition and target signal level ability of a telescope to differentiate between two objects in the sky which are separated by a small angular distance
- The measure of the fine detail that can be seen in an image. for analog systems this is typically measured in television lines or tvl. the higher the tvl rating, the higher the resolution.
- Refers to the degree of detail of an image. it is usually measured in dots per inch (dpi) or lines per inch (lpi). a high resolution gives a high quality image and vice versa.
- The quality of any digital image, whether printed or displayed on a screen, depends in part on its resolution—the number of pixels used to create the image. more and smaller pixels adds detail and sharpens edges. l optical is an absolute number that the camera`s image sensor can physically record. l interpolated adds pixels to the image using complex software algorithms to determine what color they should be. it is important to note that interpolation doesn`t add any new information to the image it just makes it bigger! camera makers often specify the resolution as: qvga (320 x 240), vga (640 x 480), svga (800 x 600), xga (1024 x 768) or uxga (1600 x 1200)
- A measure of picture resolving capabilities of a television system determined primarily by bandwidth, scan rates and aspect ratio. relates to fineness of details perceived.
- The ability to distinguish fine detail or resolve information within an image.
- Refers to the number of pixels, both horizontally and vertically, used to either capture or display an image. the higher the resolution, the finer the image detail will be.
- The quality of any digital image, whether printed or displayed on a screen, depends on its resolution, or the number of pixels used to create the image. more, smaller pixels add detail and sharpen the edges.
- 1. the amount of detail which can be seen in a microscope or on a computer monitor 2. a point in the development of a disease where the inflammation begins to disappear
- Наименьшее расстояние между деталями, обеспечивающее их захват роботом
- Разложение (на составляющие) ~ of forces разложение сил ~ of vector разложение вектора
- Resolution is a rule used in logical inference. it states that if there is an axiom of the form (a or b) and another of the form (not(b) or c), then (a or c) logically follows. see also: modus ponens, modus tollens.
- Разрешающая способность. способность значимо различать близкие значения [28].
- A measure of the fineness of detail in an image or text, usually as produced by a monitor or printer.
- Loosely speaking, the quality of an image. when printing or working with images, the resolution is usually measured in dots per inch (dpi) - the more dots per inch, the higher the quality of the image but the larger the file needed to store it. in windows, the screen resolution is how many- pixels- fit on the desktop, the most popular being 800 x 600 and 1024 x 768 - the former makes images, icons etc look bigger, but the latter means you can fit more of them on the screen.
- The process of translation between a domain name address and an ip address.
- A document that records a decision or action by a board of directors, or a bond resolution by a government entity authorizing a bond issue.
- The number of dots in an image’s screen display or printed output. a monitor’s resolution refers to the number of pixels per linear inch. printed resolution refers to dots per linear inch. (see dpi.)
- The ability to distinguish between two points in an image
- Разрешающая способность. мера способности видеокамеры или телевизионной системы воспроизводить детали. число элементов изображения, которые могут быть воспроизведены с хорошей четкостью.
- Aspect of image quality pertaining to a system’s ability to reproduce objects, often measured by resolving a pair of adjacent objects or parallel lines. see also line pair; resolving power.
- Aspect of image quality pertaining to a system’s ability to depict objects, often measured by distinguishing (resolving) a pair of adjacent objects or parallel lines.
- A system’s ability to depict two objects or signals in close proximity as separate from one another. resolution, or resolving power, varies with size, distance, sensor characteristics, object shape, object color, and contrast. see also line pair; vision acuity.
- An aspect of image quality pertaining to a system’s ability to reproduce objects, often measured by resolving a pair of adjacent objects or parallel lines.6
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).

Global positioning system, английский
- A device which uses satellite signals to accurately determine a fishing vessel's position and course.
- (gps) a satellite based radionavigation system providing continuous worldwide coverage. it provides navigation, position, and timing information to air, marine, and land users.
- Глобальная позиционирующая система, гпс
- A space-based navigation system in which orbiting satellites provide extremely accurate three-dimensional coordinates. it is officially called navstar-gps, which is short for (navigational signal timing and ranging—global positioning system) but is commonly known as gps. it was designed for and is operated by the u.s. military, which makes segments of it available for civilian use as a “public good” without charge. it can be conveniently divided into three parts. • control segment consists of tracking stations lo- 135 global cated around the world, under the overall control of a master facility at schriever afb in colorado. • space segment consists of at least 24 satellites that orbit the earth twice daily and are known as space vehicles (svs). these are spaced so that between five and eight can be sighted from any point on earth at any time. after locating at least four of them, a gps receiver can use a simple mathematical technique called trilateration to deduce its location. • public user segment has been intentionally downgraded from military precision, but still allows anyone with a gps receiver to determine latitude and longitude within 100 meters; altitude within 156 meters, and time of day within 340 nanoseconds. like any electronic device, a gps receiver can fail or malfunction, so the prudent navigator will always carry back-up in the form of traditional devices such as leadline and logline, sextant and navigation tables, chronometer, etc. see also galileo, satellite navigation.
- Система глобального позиционирования global referenceглобальная ссылка
- Глобальная система позиционирования
- A radio navigation system developed by the u.s. department of defense that uses a constellation of 24 earth satellites, which are monitored by ground-based control stations, to provide precise, continuous worldwide positioning and timing information.
