Expert system techniques have been rapidly disseminating into every scientific domain, with many applications being reported within the last decade. Expert system is bringing a new perspective. This paper introduces the towed watersaving irrigation mechanization technology firstly. Then, an emphasis is made on development of the expert system for towed water-saving irrigation mechanization tech...

Mechanization makes it feasible to calculate properties of formally speciied systems. This ability creates new opportunities for using formal methods as an exploratory tool in system design. Achieving enough eeciency to make this practical raises challenging problems in automated deduction. These challenges can be met only by approaches that integrate consideration of its mechanization into the...

The increasing cost of peanut production is a major concern in Iran. Therefore, developing the mechanization of peanut production is a necessity. In this regard, a three-phase Delphi study was conducted to identify the promoting and deterring factors affecting peanut cultivation mechanization in Guilan Province, the main peanut-producing region in Iran. After preliminary studies, 26 experts wer...

The economical situation at agricultural industry has been changed rapidly in Korea for the last 40 years. The population in farming area decreased sharply and the labor demand increased dramatically. The portion of the old and women has been increased. The farm size, and farm rural wage have been increased. Those were the driving forces of the mechanization in agricultural industry. The Agricu...

Debates over the effects of technological change on work continue to generate a wide and confusing array of findings. One reason for the lack of consensus is that empirical research based on large samples has yet to adequately address the core issue: the relationship, if any, between the level of mechanization and the characteristics of work. This relationship is explored using data from the 19...

This study aims to evaluate mechanization quality and quantity for improvement purposes. Northern Ahwaz including five districts with a total area of 286,800 hectares was selected for evaluation. The current potentials for scientific mechanization and suitable production methods in the study area were identified within the framework of a field study. In addition to a holistic study of the area ...

The mechanization of mathematics refers to the use of computers to find, or to help find, mathematical proofs. Turing showed that a complete reduction of mathematics to computation is not possible, but nevertheless the art and science of automated deduction has made progress. This paper describes some of the history and surveys the state of the art.
