Visual acuity (VA) is a measure of the ability to distinguish shapes and details objects at given distance spatial resolution visual system. Vision one basic health indicators closely related person’s quality life. It first tests done when an eye disease develops. VA usually measured by using Snellen chart or E-chart from specific distance. However, in some cases, such as unconsciousness patien...

this study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of iran at safiabad agricultural research center in 2014-2015. the cultivars included: 'gratex', '10j', 'wichita 6j', 'graking', 'choctaw' as pollinated cultivars (♀) and 'gratex', 'peruque', 'comanche 4m', &apos...

in this research, an iterative approach is employed to recognize and classify control chart patterns. to do this, by taking new observations on the quality characteristic under consideration, the maximum likelihood estimator of pattern parameters is first obtained and then the probability of each pattern is determined. then using bayes’ rule, probabilities are updated recursively. finally, when...

although control charts are very common to monitoring process changes, they usually do not indicate the real time of the changes. identifying the real time of the process changes is known as change-point estimation problem. there are a number of change point models in the literature however most of the existing approaches are dedicated to normal processes. in this paper we propose a novel appro...

Minerals are defined as naturally occurring, inorganic, solids with a definite chemical composition and a regular, internal crystalline structure. The keys to this definition are the chemical composition and the crystalline structure. Different chemical compositions result in different minerals. A good example is the mineral plagioclase. Plagioclase is a member of the feldspar group, but there ...

Knowledge of psychrometric properties is the basic requirement for environmental measurements and drying processes. The software GRAPSI_DRAW is capable of calculating the psychrometric properties and simulating the basic psychrometric processes with the precision of analytical methods, also showing the results in charts plotted on the computer screen.

To integrate Computer Aided systems (CA*-systems) in the area of Mechanical Engineering (ME) with other applications in the world of Computer Integrated Manufacturing (CIM), one principal approach under development is based on feature representation. It enables any CA*-system to recognize the higher-level entities { the so-called features in ME { out of a lower-data exchange format. In this pap...

For large e-business sites, information architecture becomes more than just what links are at the top of every page. IA becomes a strategic issue because the way that the company itself is organized, and how it does business, is directly tied to how it creates its web site. That is, a company cannot create a user-centered e-business site without being run as a customer-centered company. See any...
