A method of forming a hardcopy image (text or graphics) by generating very small drops of ink and precisely depositing them on a substrate. This concept was introduced commercially in the mid-1980s to replace dot-matrix (low cost but slow and noisy) and laser-based (high speed and high resolution but also high hardware cost) printing systems for home and office applications. As inkjet color inks and photographic-quality paper development progressed, a new goal of supplanting traditional silver halide photographs was established. Today, the home photographer can produce inkjet prints that exceed the quality and light-fade stability of color photographic prints.
Industry:Science
A method of gathering best practices for various work processes into coherent groupings to facilitate quality and process improvement. Capability Maturity Models® (CMM®) represent a relatively recent step in the evolution of process improvement techniques that enable organizations to repeatedly produce high-quality, complex, software-intensive systems faster and within expected costs. The foundations of this work include approaches to improved quality developed by W. Edwards Deming, Joseph Juran, Walter A. Shewart, and Philip B. Crosby, particularly Crosby's quality management maturity grid.
Industry:Science
A method of holding the parts of an object together with or without the aid of an adhesive such as an epoxy or a glue. Composite materials such as fiber-reinforced plastics require strong interfacial bonding between the reinforcement and the matrix. In the case of atomic or optical contact bonding, interatomic forces hold the parts together. In optical contact bonding, surface flatness and cleanliness between the mating parts determine the bonding strength, and the atoms at the surface provide the necessary forces. The number of valence electrons in the atoms of a material determines the bonding strength between the group of atoms which constitutes a molecule. In these cases the term chemical bonding is used.
Industry:Science
A method of keeping an excavated area dry by intercepting the flow of ground water with pipe wells located around the excavation area. Intercepting the flow before it reaches the excavated area also improves the stability of the edge of the excavation, permitting steeper bank slopes and often eliminating the need for supporting or shoring the banks.
Industry:Science
A method of measuring temperatures with gas as the thermometric fluid. Gas thermometry is the primary source of information about a fundamental physical parameter, temperature, over the range from about 3 to 900 K (−454 to 1160°F).
Industry:Science
A method of nondestructive testing and materials characterization that uses mechanical waves moving through materials. It is similar to seismology, except in being concerned with the scale of engineering structures, such as aircraft, bridges, and chemical tanks. When a structure is subjected to external force (or stress), a defect (for example, a crack or welding flaw) on the structure is activated and enlarged dynamically, and thus generates waves, which spread through materials at a certain speed. Such waves, known as acoustic emission signals, are detected by sensors attached on the surfaces of the structure. Mechanical vibration due to acoustic emission signals is weak and requires high-sensitivity sensors and electronic amplification before it can be analyzed.
Industry:Science
A method of obtaining age estimates on organic materials which has been used to date samples as old as 75,000 years. The method was developed immediately following World War II by Willard F. Libby and coworkers, and has provided age determinations in archeology, geology, geophysics, and other branches of science.
Industry:Science
A method of polishing metal surfaces by applying an electric current through an electrolytic bath in a process that is the reverse of plating. The metal to be polished is made the anode in an electric circuit. Anodic dissolution of protuberant burrs and sharp edges occurs at a faster rate than over the flat surfaces and crevices, possibly because of locally higher current densities. The result produces an exceedingly flat, smooth, brilliant surface.
Industry:Science
A method of presenting pulse-radar echoes in a manner that discriminates in favor of moving targets and suppresses stationary objects. Moving-target indication (MTI) is almost a necessity when moving targets are being sought over a region from which the ground clutter echoes are very strong. The most common presentation of the output of a radar with MTI is a plan position indicator (PPI) display. The moving targets appear as bright echoes, while ground clutter is suppressed.
Industry:Science
A method of quantitative multivariate analysis with the goal of representing the interrelationships among a set of continuously measured variables (usually represented by their intercorrelations) by a number of underlying, linearly independent reference variables called factors. Although the term factor analysis has come to represent a family of analysis methods, the two most commonly used approaches are the full component model, in which the entire variance of the variables (represented by unities inserted in the principal diagonal of the correlation matrix) is analyzed, and the common factor model, in which the proportion of the variance that is accounted for by the common factors (represented by communality estimates inserted in the principal diagonal) is analyzed.
