Today, innovation plays an essential role in the economic growth of countries. By evaluating technological capabilities, different approaches have considered important effects of innovation on the economic ability and superiority of countries either directly or indirectly. In recent years, the Global Innovation Index (GII) has been employed as a common framework in this respect. It consists of five components, including “institutions,” “human capital and research,” “infrastructure,” “market sophistication,” and “business sophistication,” as the inputs, and two components, including the “knowledge and technology outputs” and “creative outputs” as the outputs of innovation. The present study... 

In this research we have studied the changes in the technology performance in the smartphone industry, and by using theoretical models in technology management literature, we have compared this performance with coustomer’s required level of performance. The study shows that after 2011, the level of customer satisfactions depends less on the technology performance and more on the price. This observation is consistent with Christiensen’s suggested model for technology performance, in which after a certain point technology’s performance surpasses the customer’s need. In addition, we have studied the effect of modular design for smartphones on the customer’s satisfaction. We found that...

One of the main challenges in image processing is the reconstruction of images from their samples in the discrete domain to obtain high quality images in the continuous domain. Visual signals in the continuous domain are usually represented by discrete or digital images. This reconstruction process may not be possible in general, and we need to set some specific constraints for this purpose, such as delimiting the signal bandwidth. In this dissertation, we consider the reconstruction of binary images (black and white). These images have infinite bandwidth due to the existence of edges, and thus, the conditions of the Nyquist-Shannon sampling theorem do not hold. Novel methods have been...

The need for cooling and creating thermal comfort conditions for human life is one of today's severe challenges. Therefore, development and innovation to enhance the efficiency of these systems are of great importance. Among the new ideas proposed in this domain, we can mention the M-cycle, which can greatly improve the energy consumption for cooling systems in this sector. In this cycle, the desired cooling is produced by utilizing the latent heat of water evaporation, which is considered a kind of renewable energy. The systems based on this cycle are still under development, and for this reason, there is a necessity to better investigate the heat and mass transfer in the aforementioned... 

There has been a lively debate between two major strategist groups in innovation strategy literature. The first, with Ansoff being the protagonist, pose a rational approach in describing a corporate innovation strategy formulation process while the other group, with Mintzburg as the protagonist, prescribe an incremental approach.It seems that in continuous change and uncertainty, rational approach can weakly predict the reality and one can claim that in such situations incremental approach is more effective than rational approach. Based on the review of literature and consequent classification, most of the strategies that are named as innovation strategies in literature use rational... 

white noise or an innovation process through an all-pole filter. Applications of these processes include speech processing, RADAR signals and stock market data modeling. There exists an extensive research material on the AR processes with Gaussian innovation, however studies about the non-Gaussian case have been much more limited, while in many applications the asymptotic behavior of the signal is non-Gaussian. Non-Gaussian processes have an advantage over Gaussian ones in being capable of modeling sparsity. Assuming an appropriate non-Gaussian innovation one can suggest a more realistic description of sparse signals and predict their behavior or estimate their unknown values successfully....
