Improvements Plaque At Prescot Railway Station
Improvement is the process of a thing moving from one state to a state considered to be better, usually by a change or addition that improves. The concept of improvement is important to governments and businesses, as well as to individuals. History of the concept The term "improvement" in general means "gradual, piecemeal, but cumulative betterment", which can refer to both individuals and societies as a whole. The term "improvement" historically referred to land improvement, the process of making wildland more suitable for human uses, particularly the cultivation of crops.Alan Craig Houston, ''Benjamin Franklin and the Politics of Improvement'' (2008), p. 12. Agricultural writers contrasted "improvement" with the traditional custom that governed farming practices at the time. The belief in agricultural "improvement" was the belief that the earth could be made more fruitful. More specifically, it was the belief that "the knowledge of nature would allow the best possible use of r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartoon Guy Presents An Increasing Sales Graph
A cartoon is a type of visual art that is typically drawn, frequently Animation, animated, in an realism (arts), unrealistic or semi-realistic style. The specific meaning has evolved, but the modern usage usually refers to either: an image or series of images intended for satire, caricature, or humor; or a motion picture that relies on a sequence of illustrations for its animation. Someone who creates cartoons in the first sense is called a ''cartoonist'', and in the second sense they are usually called an ''animator''. The concept originated in the Middle Ages, and first described a preparatory drawing for a piece of art, such as a painting, fresco, tapestry, or stained glass window. In the 19th century, beginning in ''Punch (magazine), Punch'' magazine in 1843, cartoon came to refer – ironically at first – to humorous artworks in magazines and newspapers. Then it also was used for political cartoons and comic strips. When the medium developed, in the early 20th century, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoning
In urban planning, zoning is a method in which a municipality or other tier of government divides land into land-use "zones", each of which has a set of regulations for new development that differs from other zones. Zones may be defined for a single use (e.g. residential, industrial), they may combine several compatible activities by use, or in the case of form-based zoning, the differing regulations may govern the density, size and shape of allowed buildings whatever their use. The planning rules for each zone determine whether planning permission for a given development may be granted. Zoning may specify a variety of outright and conditional uses of land. It may indicate the size and dimensions of lots that land may be subdivided into, or the form and scale of buildings. These guidelines are set in order to guide urban growth and development. Zoning is the most common regulatory urban planning method used by local governments in developed countries. Exceptions include th ...

Emendation (taxonomy)
In zoological nomenclature, emendations are intentional alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon. All emendations are considered by default to be available names. An emendation may be "justified" (when the original spelling is demonstrably incorrect under the International Code of Zoological Nomenclature,International Commission on Zoological Nomenclature. 1999International Code of Zoological Nomenclature. 4th ed.London: The International Trust for Zoological Nomenclature. Article 32.5), or it may be "unjustified" (if the change violates the rules of the Code). A justified emendation is different from a " mandatory change" only in that the latter is required by the Code, under Article 34. An unjustified emendation is different from an " incorrect subsequent spelling" in that the latter is an unintentional change, while an emendation is explicitly intentional, and in that an incorrect ...

Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseband
In telecommunications and signal processing, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies. Baseband signals typically originate from transducers, converting some other variable into an electrical signal. For example, the electronic output of a microphone is a baseband signal that is analogous to the applied voice audio. In conventional analog radio broadcasting, the baseband audio signal is used to modulate an RF carrier signal of a much higher frequency. A baseband signal may have frequency components going all the way down to the DC bias, or at least it will have a high ratio bandwidth. A modulated baseband signal is called a passband signal. This occupies a higher range of frequencies and has a lower ratio and fractional bandwidth. Various uses Baseband signal A ''baseband signal'' or ''lowpass signal'' is a signal that can include frequencies that are very near zero, by comparison with its highest ...

Frequency
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. The interval of time between events is called the period. It is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), its period is one half of a second. Special definitions of frequency are used in certain contexts, such as the angular frequency in rotational or cyclical properties, when the rate of angular progress is measured. Spatial frequency is defined for properties that vary or cccur repeatedly in geometry or space. The unit of measurement of frequency in the International System of Units (SI) is the hertz, having the symbol Hz. Definitions and units For cyclical phenomena such as oscillations, waves, or for examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal-to-noise Ratio
Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. SNR is an important parameter that affects the performance and quality of systems that process or transmit signals, such as communication systems, audio systems, radar systems, imaging systems, and data acquisition systems. A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover. SNR can be improved by various methods, such as increasing the signal strength, reducing the noise level, filtering out unwanted noise, or using error correction techniques. SNR also determines the maximum possible amount of data that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preemphasis Improvement
In FM broadcasting, preemphasis improvement is the improvement in the signal-to-noise ratio of the high-frequency portion of the baseband, ''i.e.,'' modulating signal, which improvement results from passing the modulating signal through a preemphasis network before transmission. The reason that preemphasis is needed is that the process of detecting a frequency-modulated signal in a receiver produces a noise spectrum that rises in frequency (a so-called ''triangular'' spectrum). Without preemphasis, the received audio would sound unacceptably noisy at high frequencies, especially under conditions of low carrier-to-noise ratio, i.e., during fringe reception conditions. Preemphasis increases the magnitude of the higher signal frequencies, thereby improving the signal-to-noise ratio. At the output of the discriminator in the FM receiver, a deemphasis network restores the original signal power distribution. ''FM improvement factor'' is the quotient obtained by dividing the signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Vision Improvement
The Bates method is an ineffective and potentially dangerous alternative therapy aimed at improving eyesight. Eye-care physician William Horatio Bates (1860–1931) held the erroneous belief that the extraocular muscles caused changes in focus and that "mental strain" caused abnormal action of these muscles; hence he believed that relieving such "strain" would cure defective vision. In 1952, optometry professor Elwin Marg wrote of Bates, "Most of his claims and almost all of his theories have been considered false by practically all visual scientists." No type of training has been shown to change the refractive power of the eye. Moreover, certain aspects of the Bates method can put its followers at risk: They may damage their eyes through overexposure to sunlight, not wear their corrective lenses when they need them (e.g., while driving), or neglect conventional eye care, possibly allowing serious conditions to develop. Early history In 1891, Bates published an articl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improvement Era
The ''Improvement Era'' (often shortened to ''The Era'') was an official magazine of the Church of Jesus Christ of Latter-day Saints (LDS Church) between 1897 and 1970. History The ''Improvement Era'' was first published in 1897 as a replacement to the unofficial magazine, '' The Contributor''. Over the years, it was the official publishing organ for a variety of organizations within the Church of Jesus Christ of Latter-day Saints, including the Seventies, the Young Men's Mutual Improvement Association, the Young Ladies' Mutual Improvement Association, priesthood quorums, church schools, the Church Music Committee, and the Home Teaching Committee. In the July 1960 issue, an insert targeted toward the teenagers of the church was included. Entitled "The Era of Youth," it continued to be included in the ''Improvement Era'' until 1970, when it became the basis for the '' New Era''. With the implementation of the Priesthood Correlation Program in 1970, the ''Improvement Era'' ceas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improvement Districts Of Alberta
The province of Alberta, Canada, is divided into ten types of local governments – urban municipalities (including cities, towns, villages and summer villages), specialized municipalities, rural municipalities (including municipal districts (often named as counties), improvement districts, and special areas), Métis settlements, and Indian reserves. All types of municipalities are governed by local residents and were incorporated under various provincial acts, with the exception of improvement districts (governed by either the provincial or federal government), and Alberta's Indian reserves (governed by local band governments under federal jurisdiction). Alberta also has numerous unincorporated communities (including urban service areas, hamlets and a townsite) that are not independent municipalities in their own right. However, they are all recognized as sub-municipal entities by Ministry of Municipal Affairs under the jurisdiction of specialized municipalities or ru ...
