In scientific and commercial fields associated with modern agriculture, the categorization of different rice types and determination of its quality is very important. Various image processing algorithms are applied in recent years to detect different agricultural products. The problem of rice classification and quality detection in this paper is presented based on model learning concepts includ...

I study a dynamic one-sided-offer bargaining model between a seller and a buyer under incomplete information. The seller knows the quality of his product while the buyer does not. During bargaining, the seller may receive an outside option, the value of which depends on the quality of the product. If the outside option is sufficiently important, there is an equilibrium in which the uninformed b...

In technical learningthe subjective steps of creativity process i.e. "insight", "preparation", "incubation", "intuition", and "verification"were discussed and it was suggested that these steps cannot be taught ...

We study investment cycles and information flows in a model of social learning in which investment returns fluctuate according to a Markov process. In our Waiting Game, agents observe the investment history and a private signal correlated with the current period’s investment return. Agents then decide whether to invest in round 1 or to delay their decision to round 2 of the current period. Casc...

Ever since the start of the Industrial Revolution in Britain in the 1760s, innovation and investment have been crucial elements in economic explanations of the dynamics of capitalism. Classical economics recognises that innovation embodied in the form of new machines through fixed capital investment is the essential process for realising economic development. This study sets up a theoretical li...

This study has developed a production inventory model where the cycle timeis fuzzy, the existence of defective products is assumed in each batch andproduct screening is performed both in-production and after-production.Triangular fuzzy numbers serve to model uncertainties in the cycle time, anda fuzzified total inventory profit function is created by thedefuzzifica...

Procurement of manufactured goods and sub-assemblies from distant markets is not a recent phenomenon. Countries with significantly lower labor costs have been providing new opportunities for the large firms of the developed countries for decades. Although it makes higher margins possible for the big brand owners in the domestic and global retail markets, there are obvious risks such as the ones...
