The counting of papers and citations is fundamental to the assessment research productivity impact. In an age increasing scientific collaboration across national borders, produced by between multiple countries, such papers, raises concerns in country-level evaluation. this study, we compared number counts country ranks resulting from five different methods. We also observed inflation depending on method used. Using 1989 2008 physics indexed ISI's Web Science as our sample, analyzed results...

This paper proposes a design methodology for the synthesis of statically balanced planar articulated manipulators through direct spring installation. The proposed method can determine all admissible configurations installation with given manipulator. fundamental principle gravity balance conservative system spring-gravity is formulated by stiffness block matrix, wherein each component matrix implies interacting forces among links. distribution nonzero-component matrices be related to type...

A novel methodology for the design of a gravity-balanced serial-type spatial manipulator is presented. In design, gravity effects system can be completely compensated at any configuration. The balance n-DOF achieved by suspensions only n zero-free-length springs, where each spring individually fitted between primary link and its adjacent auxiliary link. No has to installed across from far remote ground such that motion interference among springs links prevented. Besides, since embedded along...

The nature of funding sources for university-industry collaboration (UIC) has gradually changed, which may motivate universities to pursue different goals. Therefore, a question arises concerning whether and how influence the innovation performance universities. This study explicates this relationship by using organisational control theory. Results structural equation modelling partial least squares based on sample 146 Taiwanese revealed that both governmental industrial facilitated UIC...
