Virtual private network uses a public network infrastructure to make the connections among geographically dispersed nodes, instead of using cables owned or leased exclusively for one single networks use, as is typical for a wide area network. To the user, a VPN looks just like a private network, hence the virtual in its name, even though it is sharing a web of cables with the traffic of hundreds or thousands of other users at the same time. It has all the characteristics of a private network-limited access to only authorized users, for example it shares the same public infrastructure with other users.

Virtual prototyping is the process of using a virtual prototype, in lieu of a physical prototype, for test and evaluation of specific characteristics of a product design. It is known as simulation-based-design, refers to the iterative design refinement of a designed product using a computer-based functional physical simulation. It is rapidly gaining importance as the engineering practice of choice to aid rapid product development and shorten the design cycle. The enabling trends for the adoption and rapid proliferation of the virtual prototyping methodology include: ubiquitous availability of low-cost PC-based parametric simulation/analysis tools and integration of multi-physics simulations into a unified environment.

Portable Viscometer is small, battery-operated rotational viscometers suitable for quick & reliable tests and comparative measurements for quality control applications. Portable viscometer are used in conjunction with a belt mounted computer, for making field viscosity measurements and for taking samples of various liquids such as paint mixes, asphalt cements, liquid asphalts, asphalt & emulsions. A portable viscometer includes an instrument body having an electrical control circuit and sensor probe for immersion into a fluid to be analyzed.

Viscometers are used for measuring the viscosity and flow properties of fluids. It measures the force required to rotate a disc or hollow cup immersed in the specimen fluid at a predetermined speed. It measure viscosity in a wide range of centipoise (cp) for a variety of industrial and laboratory applications. The four-digit LCD ensures easy reading of both centipoise (cp) or millpascal seconds (mPaS), as well as percent torque, and speed. Display also shows spindle number. Choose the low-range models (15 to 2,000,000 cp) to measure low-viscosity materials such as oils, solvents, paints, and coatings. Choose the medium-range models (100 to 13,000,000 cp) to measure medium-viscosity materials such as sauces, adhesives, creams, and varnishes. Choose high-range models (800 to 104,000,000 cp) to measure high-viscosity materials such as epoxies, gels, and tars. Just flip a switch and turn a dial to set the speed and spindle code. Each model has 18 selectable rotational speeds, plus a set of standard spindles. Adjust rotational speed and spindle type to measure the desired centipoise range

Viscosifiers are organic water-soluble polymers. They are used at low concentrations and provide viscosity & in some cases gel strength and fluid loss control in a variety of waters & brines and facilitate the maintenance of low-solids muds. These viscosifiers are used in shampoos and bath products. The viscosifiers provide viscosity at low temperatures without building progressive gel strengths with increasing temperature.

Viscosity cups measure the time required for a given volume of adhesive to flow through an orifice in the bottom of a metal cup containing an accurately known volume of material. It is used to measure the thickness or fluidity of the mixed materials, usually paint. The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.
