a power divider (pd)/ power combiner (pc) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (siw) technology is proposed. an siw cavity is designed to provide a high quality factor filtering response and an smd resistor is attached between two output ports to realize the high isolation. the value of the applied resistor is calculated by using the ...

A novel and robust scheme for radix-4 Booth scheme implemented in Carbon Nanotube Field-Effect Transistor (CNTFET) technology has been presented in this paper. The main advantage of the proposed scheme is its improved speed performance compared with previous designs. With the help of modifications applied to the encoder section using Pass Transistor Logic (PTL), the corresponding capacitances o...

Most scientific studies on innovation deal with high-technology sectors, although medium-technology industries are still the most relevant contributors to employment and market shares in Europe. Based on three different methodological approaches (social network analysis, regression analysis and qualitative research), the importance of technology-specific, firm-specific and region-specific facto...

The role of human capital composition has been given importance in the most recent endogenous growth models. Assuming that primary as well as secondary education is more suitable for imitation and higher education is more appropriate for innovation, this paper empirically investigates whether the contribution of human capital to productivity growth depends on the composition of human capital an...

The aim of this paper is to investigate collaborative innovation in business networks for small environmental technology companies entering an emerging market (EM). Export of environmental technology solutions to emerging economies involves high investment opportunities and high growth potential, but also high risk. For example, large-scale demonstrator equipment proving the function of the env...

The purpose of this study is to provide a model with a dynamic system method to investigate the factors affecting the technological capabilities enhancement in the high-tech industries of high-speed train of the rail transportation system. For this purpose, after reviewing the literature and conducting several meetings with experts in the rail transportation industry, a conceptual and qualitati...

Background: Technology acceptance model (TAM) has been extensively used to analyse user of technologies adopted by enterprises at different levels. Moreover, the technology adoption drawn attention among practitioners and academic communities alike, leading development approaches understand concept. However, there is a degree inconsistency found in previous studies on types TAM models explainin...
