1. Motivation Multiple remote tower control aims at enabling one air traffic controller (ATCO) to control simultaneous traffic at two airports at the same time. This concept has the advantage that workforce of the ATCOs can be utilized in an optimized way. Nevertheless, it raises the questions how the workplace should be designed in order to allow the ATCO to handle as much traffic as possible ...

Since more than fifteen years an increasing interest is observed worldwide in remote control of low traffic airports by means some kind virtual tower. As outlined the Foreword Steve Ellis and Preface to 1st ed. this book, “Virtual Tower” depicts idea replacing out-of-the-window (OTW) view from a conventional tower on Remote Tower Control Center (RTC) relying advanced video, image processing, re...

The Hybrid Ground Source Heat Pump (GSHP) system features the combination of ground heat exchanger (GHE) and cooling tower for rejecting the cooling load, which enables the use of the renewable resource of geothermal energy while reducing the cost of installation for applications of high cooling demand. However, model based control for efficient operation of the GSHP system can be intricate due...

Abstract Tower cranes find wide use in construction works, ports and several loading unloading procedures met industry. A nonlinear optimal control approach is proposed for the dynamic model of 4-DOF underactuated tower crane. The robotic crane undergoes approximate linearization around a temporary operating point that recomputed at each time-step method. relies on Taylor series expansion assoc...

This paper presents the modeling and stabilization of a floating offshore wind turbine (FOWT) using oscillating water columns (OWCs) as active structural control. The novel concept this work is to design new FOWT platform ITI Energy barge with incorporated OWCs at opposite sides tower, in order alleviate unwanted system oscillations. provide necessary opposing forces bending moment upon tower w...

in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...
