equipment availability is necessary in the development of agriculture mechanization. crop thinning is one of the most important stages in row crop production which is laborious and costly. the objective of this project is design and construction of a row crop thinning machine. four main system units are plant sensors, ground sensors, control and thinning platforms. in this machine the unwanted ...

In this research, a system is proposed for detecting fertility of eggs. The system is composed of two parts: hardware and software. The fabricated hardware provides a platform to obtain accurate images from inner side of the eggs, without harming their embryos. The software part includes a set of image processing and machine vision processes, which is able to detect the fertility of eggs from c...

Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...
