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 automatic conversion of Fortran 77 to C can be accomplished using f2c, but the generated code is difficult to read and maintain, and needs to be linked with various non-standard run-time libraries which provide input/output and mathematical routines. This paper describes tools that have been developed at NAG Ltd to automatically replace non-standard run-time f2c input/output functions with ...

We present an algebra of discrete timed input/output automata that execute in the context of different clock granularities — timed machines — as models of systems that can be dynamically interconnected at run time in a heterogeneous context. We show how timed machines can be refined to a lower granularity of time and how timed machines with different clock granularities can be composed. We prop...

Converting a conventional contract into an electronic equivalent that can be executed and enforced by computers is a challenging task. The difficulties are caused by the ambiguities that the original humanoriented text is likely to contain. The conversion process involves the conversion of the original text into mathematical notation. This paper discusses how standard conventional contracts can...
