in this paper, a novel hybrid method based on learning algorithmof fuzzy neural network and newton-cotesmethods with positive coefficient for the solution of linear fredholm integro-differential equation of the second kindwith fuzzy initial value is presented. here neural network isconsidered as a part of large field called neural computing orsoft computing. we propose alearning algorithm from ...

graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (lda). band structures and density of states for the propose carbon 3d models are reported. a finite energy gap and...

malting is a complex biotechnological process that includes steeping; germination and drying of cereal grains under controlled conditions of temperature and humidity. in this research malting process parameters were predict by modular neural network with different activation function included, logsig-logsig, tanh-tanh, logsigtanh, logsig-identity and tanh-identity. steeping time (x1) and germin...

A logic network to produce the sequency ordered Hadamard matrix H based on the property of gray code and orthogonal group codes is developed. The network uses a counter to generate Rademacher function such that the output of H will be in sequency. A general purpose shift register with output logic is used to establish a sequence of period P corresponding to a given value of order m of the Hadam...

Although intuitively clear, implementing the principle of postponement is challenging in business practice since it involves configuring a complete supply chain thereby hindering business implementation. An alternative approach to timing product supplies from a single firm perspectiveembedded in value network context is proposed based on more recent studies on the principles of postponement and...

Real-world social networks are dynamic in nature. Companies continue to collaborate, align strategically, acquire, and merge over time, and receive positive/negative impact from other companies. Consequently, their performance changes with time. If one can understand what types of network changes affect a company’s value, he/she can predict the future value of the company, grasp industry innova...

Networks are assumed to enhance tourism small firms’ performance and competitiveness. Research indicates that there are different sources of values that could derive from these networks such as cost and time efficiency, quality improvement, flexibility and innovation. However, in most cases, these values are associated to a general framework of what Information Communication Technologies (ICT) ...

This paper examines emerging industries that exhibit positive network effects. We put forward a dynamic model in which two technologies compete to be the standard. The model provides a quantitative method for the valuation of firms. We use the model to examine the relationship between network effects, consumer heterogeneity, and prices. We show that the firm value depends strongly on the partic...
