in this research، job opportunities have been examined among 26 productive sectors of iran's economy by using input-output table in 2001.from viewpoint of employment ،production and value added، the key sectors has been diagnosed by using mri ، elasticity of input-output table، backward and forward linkages and june's corrective methods. then، job opportunities has been analyzed among...

wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

in this paper, rst a design is proposed for representing fuzzy polynomials withinput fuzzy and output fuzzy. then, we sketch a constructive proof for existenceof such polynomial which can be fuzzy interpolation polynomial in a set given ofdiscrete points rather than a fuzzy function. finally, to illustrate some numericalexamples are solved.

the sources of output growth of iranian agriculture over the years 1986-2001 has been examined, using a decomposition method within the input-output (io) framework. the three comparable io tables of 1986, 1991, and 2001 have been employed as the main data sources. output changes from a demand side perspective, and decomposition of the growth of output into components attributable to consumption...

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...

The article presents an original ship course-keeping algorithm based on a knowledge base. Its integral part is a computer-borne ship movement dynamical model based on a set of signals obtained from the object’s input and output. This way problems occurring while designing classic control algorithms for a complex, non-linear ship model have been avoided. The presented methodology is general in t...

A common architecture here unifies ordinary scalar deltasigma modulators, vector I/O delta-sigma modulators (including parallel banks of scalar ones), mismatch-shaping DACs, delta-sigma modulators incorporating mismatchshaping DACs in the conventional way, and something new: scalar or vector delta-sigma modulators incorporating spectral shaping of hardware mismatches as a natural and integral p...
