Fourier Domain Scoring (FDS) has been shown to give a 60% improvement in precision over the existing vector space methods, but its index requires a large storage space. We propose a new Web text mining method using the discrete cosine transform (DCT) to extract useful information from text documents and to provide improved document ranking, without having to store excessive data. While the new ...

A new form of microprocessor-controlled arthrograph is described which measures stiffness parameters of the metacarpophalangeal joints of the index, middle, and ring fingers of both hands. The apparatus is simple and quick to use and gives reproducible results. The arthrograph is used to determine the reference limits for stiffness at the middle finger of the right hand in 128 normal subjects. ...

The present study was conducted to compare precision and traditional agriculture by budgeting technique. Its statistical population consists of 210 experts in agricultural jihad organization of Qom province. The validity of Questionnaire as research tool ware confirmed by professors while its reliability was corroborated by Cranach’s alpha to 0.78-0.94 intervals. According to the findings, ther...

objective: the aim of the current research was to investigate the effectiveness of precision teaching on reading ability of students with learning disability. method: the research method was semi- experimental with pretest – posttest design. statistical population consisted of all the 3 rd grade elementary girl students with learning disability in city of isfahan during 1389-1390 academic years...

For several years we have been studying the use of Fabry-Perot interferometers for precise measurement of the refractive index of gasses, where the primary motivation has been to improve interferometer-based length measurement. Because the refractive index of a gas depends on its pressure and temperature, we can also use refractive index to monitor either of these quantities if the second is kn...

ÐThis paper deals with the computation of reciprocals, square roots, inverse square roots, and some elementary functions using small tables, small multipliers, and, for some functions, a final alargeo (almost full-length) multiplication. We propose a method, based on argument reduction and series expansion, that allows fast evaluation of these functions in high precision. The strength of this m...

In today’s hi-tech and hi-precision world, robot finds its application in many areas to carryout operations that are either routine, highly complex and critical, hazardous or of high-precision nature. Robots when networked offer many benefits such as increased maneuverability and efficiency. This paper makes a survey on the present developmental status and details the design features of network...

Two high-performance liquid chromatographic methods are compared for the determination of monoand oligosaccharides in vegetables using an N H 2 column and acetonitrile-water as the mobile phase. One method uses a gradient elution and evaporative light-scattering detection; method precision (relative standard deviation) ranges from 1.09 to 4.44%, and detection limits range from 0.014 to 0.061 mg...

Each learner has his own learning style that helps him study easier. Many researchers have been concentrating in determining learners’ learning styles to aim at efficiency in implementing adaptation in learning management systems. Automatic and dynamic detection of learning style has its attractive advantages in precision and time saving. In this paper, we propose a new method that automaticall...
