Tape Correction (surveying)
In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension. Not correcting for these effects gives rise to systematic errors, i.e. effects which act in a predictable manner and therefore can be corrected by mathematical methods. Correction due to slope C_v =2L*sin^2 + \frac Where L= Inclined length measured A= Inclined angle When distances are measured along the slope, the equivalent horizontal distance may be determined by applying a slope correction. The vertical slope angle of the length measured must be measured. (Refer to the figure on the other side) Thus, :*For gentle slopes, m30\% ::C_h = s(1-\cos \theta), ::Or, more simply, d = s * \cos \theta Where: :C_h is the correction of measured slope distance due to slope; :\theta is the angle between the measured slope line and horizontal line; :s is the mea ...

Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designed positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, LiDAR sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface locators, d ...

Yield (engineering)
In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible and is known as plastic deformation. The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing permanent deformation. In some materials, such as aluminium, there is a gradual onset of non-linear behavior, making the precise yield point difficult to determine. In such a case, the offset yiel ...

Baguio
Baguio ( , ), officially the City of Baguio ( ilo, Siudad ti Baguio; fil, Lungsod ng Baguio), is a 1st class highly urbanized city in the Cordillera Administrative Region, Philippines. It is known as the "Summer Capital of the Philippines", owing to its cool climate since the city is located approximately above mean sea level, often cited as in the Luzon tropical pine forests ecoregion, which also makes it conducive for the growth of mossy plants, orchids and pine trees, to which it attributes its other moniker as the "City of Pines". Baguio was established as a hill station by the United States in 1900 at the site of an Ibaloi village known as ''Kafagway''. It was the United States' only hill station in Asia. Baguio is classified as a Highly-Urbanized City (HUC). It is geographically located within Benguet, serving as the provincial capital from 1901 to 1916, but has since been administered independently from the province following its conversion into a chartered cit ...

With a starting capital of (), the Ramoses set up their first retail bookstore selling GI novels, textbooks and supplies. During World War II, the store shifted to selling sold candies, soap, and slippers due to stringent book censorship. The store experienced success but was burned down during the 1945 Bat ...

Local Attraction
While compass surveying, the magnetic needle is sometimes disturbed from its normal position under the influence of external attractive forces. Such a disturbing influence is called as ''local attraction''. The external forces are produced by sources of local attraction which may be current carrying wire (magnetic materials) or metal objects. The term is also used to denote amount of deviation of the needle from its normal position. It mostly causes errors in observations while surveying and thus suitable methods are employed to neglect these errors."Compass Surveying" by C. L. Kocher, Principal of Mehar Chand Polytechnic College, Jalandhar City, Punjab Sources The sources of local attraction may be natural or artificial. Natural sources include iron ores or magnetic rocks while as artificial sources consist of steel structures, iron pipes, current carrying conductors. The iron made surveying instruments such as metric chains, ranging rods and arrows should also be kept at a safe di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standardization
Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, or quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of ''standardization'' is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. History Early examples Standard weights and measures were developed by the Indus Valley civilization.Iwata, Shigeo (2008), "Weights and Measures in the Indus Valley", ''Encyclopaedia of the History of Science, Technology, and Medicine in Non-Western Cultures (2nd edition)'' edited by Helaine Selin, pp. 2254–2255, Springer, .
