It is beyond dispute that technological change acts as a driver of economic growth. In developing countries where highly suffer from lack of this process, incremental innovation is considered as main source of technology capability building and development In moving toward this pass and to meet with time pressure of catching up, developing countries acquire the initial required knowledge base through technology absorption from outside sources; On the other hand as development is a lengthy process, it is important that the absorbed knowledge still has the potential of more advancement in future. Therefore a selection instrument with ability of assessing different knowledge base or... 

Purpose: This research attempts to formulate an analytical model for the studying and assessment of necessary factors that have strong effects on the level of Iranian Technology Park competitiveness. The result of this model leads to increasing the effectiveness and efficiency of Technology Parks planning stage. Methodology/Approach: The main framework of this research is based on studying the projects and research, which in their methods use the Porter's diamond model or SWOT analytical method. On the other hand, this framework is customized for the future needs of Technology Parks and clarifies the kind of information that must be gathered. Finding: Identification of the core competencies... 

In this paper, to set R&D priorities at sector level, a developed method is proposed which is combined of scenario planning and critical technologies method and then applied for prioritizing R&D issues of membrane technology in National Iranian Gas Company (NIGC). In the first phase (through 3 steps), scope of NIGC is mapped using national documents and viewpoints of experts and managers. This map includes main process of gas processing and gas conversions. Then strategic goals of gas industry including gas exports, conversions, injection and internal use, are developed. Also Strategic Technology Units (STUs) are identified and twenty distinct membrane technologies including technologies of... 

To have a sustainable economy and environment, several countries have widely inclined to the utilization of non-fossil fuels like biomass fuels to produce heat and electricity. The advantage of employing biomass for combustion is emerging as a potential renewable energy, which is regarded as a cheap fuel. Chemical constituents or elements are essential properties in biomass applications, which would be costly and labor-intensive to experimentally estimate them. One of the criteria to evaluate the energy of biomass from an economic perspective is the higher heating value (HHV). In the present work, we have applied multilayer perceptron artificial neural network (MLP-ANN), least-squares...
