Parameters optimization of the PI controller was investigated for the header flux control of Ultra-fast cooling. Taking the measured curve, Ultra-fast cooling (UFC) header flux under different open rate of valve, as the input parameters, a simulation model was developed. Based on the coupling control of proportion(P) and integration(I), the parameters with minimum root-mean-square-error of header flux was considered as the best. The simulation results showed that the optimal integration time was 600ms under industrial conditions. Furthermore, the collection equations for the P and I controller were established by the newly developed simulation model. The results from the 011-site implementation indicated that the flux deviation between target and measured values was less than ±1.0m3/h during the constant operation of the UFC header, and the overshoot value was within 3.0in3/li of the apparent interference.

Trough collectors are laid out in rows in a field withrow spacing. Wind and sandstorm loads on the collectors will be influenced by surrounding collectors.This paper presents analyzed results from a combined wind tunnel and sandstorm tunnel study on a trough collector field with seven rows and five spans. In wind tunneltests, the measured model with pressure taps was installed in the field to measure wind pressures on the surfaces. Mean and fluctuating pressures on the model were measured by the synchronous multi-pressure sensing system under typical boundary layer wind flow field.In sandstorm tunneltests,a isolated trough collector model was measured by the high-frequency force balance technique under wind-blown sand flow field.

In this paper, the researcher analyzes the architecture of cultural heritage temples with a common thread with Chinese culture. The paper's objective was to explore the element of this heritage and historic temple building in the eighteenth century that stands a sustainability architecture for decades, including the interior layout based on Chinese character and the temple's architectural ornament. In order to preserve this temple so that it remains unique, renovations were carried out while adhering to the original architectural form of the Chinese character. This paper was to show the society about the architecture of the temple that had been preserved from time to time according to its original form that supports the character of Chinese culture in Jakarta. This research used observation and literature study to support pictures and data from the temple. Literature related to Chinese architecture had been reviewed to provide sufficient data for discussion about the elements of this Chinese temple. This paper shows that the temple still maintains the character of Chinese architecture form as when it was first founded and considered a form of preservation of the historic building. This study not only will give a good impact on society to recognize this temple but also be known as a sustainable architecture in the future. [ABSTRACT FROM AUTHOR]
