We investigate the innovation function of a think tank in the course of modernization of the German public sector. Our focus is on the framing strategy the think tank pursues in order to disseminate new knowledge. We select publications released by the think tank and conduct a textual analysis on them in order to reveal the frames for which they serve as vehicles. Three stages of the framing pr...

The auxiliary latitudes are essential tools in cartography. This paper summarizes methods for converting between them with an emphasis on providing full double-precision accuracy. includes series expansions the third flattening, where truncation error is precisely measured and estimates of radii convergence given. Also new formulas given computing rectifying authalic minimal roundoff error.

Three-dimensional tank in smooth tank is of concern in various engineering applications. Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in past several decades and many significant phenomena have been considered in those studies, especially the linear and nonlinear effects of sloshing wave with inviscid or viscid liquid in a tank. The reported stu...

Consider a rectangular tank containing an inviscid incompressible and irrotational 'uid. The tank is subject to a one-dimensional horizontal move (the control) and the motion of the 'uid is described by the shallow water equations. By means of a Lyapunov approach, control laws that stabilize the state of the 'uid–tank system are derived. Two classes of control are considered: full-state feedbac...

In this study, a solar single/double-effect switching LiBr-H2O absorption refrigeration system was investigated to make full use of energy and give play the advantages systems. A corresponding thermodynamic dynamic mathematical model developed. The operation characteristics operating continuously for one week were analyzed. order highlight system, it compared with other forms systems compressio...

In process industries, control of liquid level in the process tank is important and complicated issues. In this work, authors have represented a case study involving mathematical modeling, system identification, and controller design of a three tank conical interacting level system (TTCILS). A nonlinear tank is identified mathematically and an auto tuning method of PID controller is implemented...
