· One property that makes the study of a random process much easier is the "Markov property". In a very informal way, the Markov property says, for a random process, that if we know the value taken by the process at a given time, we won''t get any additional information about the future behaviour of the process by gathering more knowledge about the past.
· Nanoparticles Types, Properties and Uses. Synthetically produced nanoparticles play an important role in nanotechnology. They are a wide class of materials whose extension in all three dimensions lies between 1 and 100 nanometers. Nanoparticles are now being used for instance in the manufacture of scratchproof eyeglasses, crack-resistant paints ...

· Oil sands are sometimes referred to as tar sands or bituminous sands. The exact composition of Alberta''s oil sands can vary greatly, even within the same geological formation. A typical oil sands deposit contains about 10% bitumen, 5% water and 85% solids. However, the bitumen content can be as high as 20% in some areas.
· Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.
· The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure ...

A process typically relying on silica-based materials, sand castings process involves finely ground, spherical grains tightly packed together into a smooth molding surface. Advantages This is the least expensive process when producing small quantities (normally less than 100) and also boasts with the least expensive tooling.
Artificial sand also called manufactured sand or crushed sand, the artificial sand are manufactured by crushing rocks, stones or larger aggregates into small size particles in the quarry. Recent years, with the decrease of natural sand, the market of artificial sand shows great potential and vitality.
synthetic fuel Renewable/Alternative. a liquid or gaseous fuel derived from a source such as coal, shale oil, tar sands, or biomass, used as a substitute for oil or natural gas. See next page. synthetic fuel A generic term applied to any manufactured fuel with the approximate composition and comparable specific energy of a natural fuel.

Forming Process also known as Metal Forming is a large set of the manufacturing process by which a raw material converted into a product. In this process, we apply stresses like tension, compression, shear, etc. to deformed the raw material. The example of forming processes are sheet metal manufacturing, forging, rolling, extrusion, wire drawing, thread rolling, rotary swinging, and so on.
Also, the physical and chemical properties of the membrane are important for the process (Street et al., 2014). Depending on their structure and chemical composition, membranes can also be grouped as: (1) isotropic, having uniform physical nature and chemical composition in cross-section; and (2) anisotropic, which are nonuniform in cross-section.
