Surveying Dictionary Words Definitions Starting from Q, R, S
Query: The process of selecting features in a database. Can be achieved through a query language directly on the data or, in a GIS, by interactively selecting features. Raasterization: The process that converts vector data, which is a series of points, lines and polygons into raster data which is a series of cells with a discrete value. Railroads: A category of rural transportation
Reasons to Keep Factor of Safety in Building Construction
Factor of Safety in buildings or other construction is kept so that to compensate any uncertainty in the design process. The uncertainty could come from anywhere in the design process including calculations, material strengths, environmental conditions, natural phenomenons, duty of the structure and last but not the least quality of materials used. Though there exist some
What is Plaster of Paris and How to Make it at Home?
Plaster of Paris is a Calcium sulfate semi-hydrate (CaSO4,½ H2O) derived from Gypsum, a calcium sulfate di-hydrate (CaSO4, 2H2O), by firing this mineral at relatively low temperature and thus reducing it to powder. In 1700’s, Paris was already the “Capital of plaster” since all the walls of wooden houses were covered with plaster, as a protection against fire. The KingBasics and Principles of Plastic Analysis
Plastic analysis is defined as the analysis in which the criterion for the design of structures is the ultimate load. We can define it as the analysis inelastic material is studied beyond the elastic limit (which can be observed in stress strain diagram). Plastic analysis derives from a simple mode failure in which plastic hinges form. Actually the ultimate load is found from the
What is a Partnership Organization

The success of partnership depends upon mutual confidence understanding, co-operation & adjustment of the members to accommodate & appreciate each other’s view.

Physical Features of the Earth
Physical features refer to the natural characteristics and elements of a particular geographical area. They include various aspects such as mountains, rivers, slopes, plains, and other landforms. These features are essential for understanding the topography and geography of a region. The physical features map includes the existence of the: Mountains Rivers Slope or plain area
Definition, Types & Comparison of Open & Pipe Flow
It is usually the flow in an Open Channels Surface Flow: The flow which is above the ground level is called surface flow. Ground Flow: The flow which is below the surface of the earth is called ground flow. Open channel flow is not completely enclosed by boundaries, unlike pipe flow. Open channel is always under the action of gravity, while pipe can be under gravity
Passenger Car Unit - Definition & Examples
It is a vehicle unit used for expressing highway capacity. One car is considered as a single unit, cycle, motorcycle is considered as half car unit. Bus , truck causes a lot of inconvenience because of its large size and is considered equivalent to 3 cars or 3 PCU. Volume: Number of vehicles crossing a point on the road during a specific time period. It is carried out for:
Methods of Sewage Waste Disposal
There are several methods for sewage waste disposal, and the most appropriate method of sewage disposal depends on various factors such as the scale of the system, available infrastructure, local regulations, Dry or conservatory system Water carriage system (99.9)
Methods for Non Destructive Testing of Concrete
Non destructive testing of concrete can be defined as the test method used to examine the properties of concrete used in the actual structure. These test methods can also be said as in-situ tests or in-place tests. Traditionally these tests are said to be as the non-destructive test although some minor damage to the structure may be involved. An important feature of nonMechanics of Solids Lecture Notes
It is the combination of physical, mathematical, and computer laws and techniques to predict the behavior of solid materials that are subjected to mechanical or thermal loadings. It is the branch of mechanics that deals with the behavior of solid matter under external actions. The external actions may be: External Force Temperature Change Displacement
Road Maintenance - Highway Maintenance
Preserving and keeping each type of roadway, roadside, structures as nearly as possible in its original condition as constructed or as subsequently improved and the operation of highway facilities and services to provide satisfactory and safe transportation, is called maintenance of Highways or Road Maintenance. Surface maintenanceSurveying Dictionary Words Definitions Starting from M, N, O, P
Magnetic declination is the horizontal angle between true north (i.e., the geographic meridian) and magnetic north (i.e., the magnetic meridian). There are two conventions for specifying the angle. One is to indicate the magnitude (e.g., 6o) and direction as E or W of north. The other considers positive values to be toward the east and negative values to be toward the west.
