In this investigation, an intelligent control system has been developed for Compact Multiphase Separation System (CMSS©) which consists of integrated configurations of three compact separators, namely, Gas-Liquid Cylindrical Cyclone (GLCC©), Liquid-Liquid Cylindrical Cyclone (LLCC©) and Liquid-Liquid Hydrocyclone (LLHC). This is a two-part paper, the first part deals with the Modeling and Simulation of the CMSS© and the second part (current paper) deals with Experimental Investigation. A new dual differential pressure sensor system has been implemented and tested for GLCC©, to eliminate the error in liquid level measurement due to change in watercut. A new watercut based control system using downstream pump speed control has been designed and tested for the LLCC© system. A new cascaded control strategy for change in set-point of differential pressure ratio using underflow quality from hydrocyclone has been designed and developed. Comparison of CMSS© performance simulator and experimental results shows that the control system simulator is capable of representing the real physical system and can be used to validate the controller design. Fuzzy logic controller has been successfully implemented and tested. Experimental results show a similar trend as the dynamic simulator results for the various input conditions and scenarios. The results from theoretical and experimental studies have shown that Free Water Knock Out (FWKO) CMSS© system can be readily deployed in the field using the control system strategies designed, implemented and tested in this study. Reliability analysis for FWKO CMSS© system has been conducted. System reliability has been calculated from reliability of components and performance reliability of the system. A new protocol has been introduced to calculate performance reliability based on performance failure of the system from simulation data. This protocol has been proven to predict performance reliability of a new system which does not have prior information on failure of components or devices.

Demonstrative Pronouns

In this paper we report the results of two experimental studies in which we tested the claim of Hinterwimmer and Bosch (2017) that German demonstrative pronouns are anti-logophoric pronouns: They avoid discourse referents as antecedents that function as perspectival centers. In both experiments we tested the interpretative options of demonstrative pronouns in text segments which were either perspectivally neutral or in which the narrator’s or a topical protagonist’s perspective was foregrounded. Taken together, the experimental results are most compatible with a slightly modified version of the analysis argued for in Hinterwimmer and Bosch (2017) according to which topical discourse referents in neutral narration automatically become perspectival centers.

To study the possibilities of volatilization in the asphalt pavement during service process, this paper presented an experimental investigation in the laboratory-based environment by simulating the circumstances of Infrared (IR) and Ultraviolet Radiation (UV). The Vacuum (Va) condition was also conducted to discuss the possibilities of volatilization in the asphalts. The changes of asphalt mass, chemical compositions and viscosity were conducted to analyze the experimental results. All the results on the circumstance of Va, that the decrement of asphalt mass, the decrement of light components and the increment of VI values, indicated that there may exist the volatilization in the asphalt. Different trends between IR and UV with asphalts demonstrate that the volatilization is affected by asphalt species and environmental conditions. In addition, ultraviolet radiation may take a vital role on the volatilization of asphalt.

Critical Cavitation

Results of analytical and experimental studies of cavitation in valve-controlled hydraulic actuators under various dynamic conditions are presented. The analytical work consists of deriving approximate critical cavitation conditions for various operating modes. The experimental investigation includes both a high-speed photographic study of cavity formation and tests to check the validity of the derived cavitation conditions. Close agreement between analytical and experimental results was obtained. The mechanisms governing cavity formation and cavitation effects are discussed qualitatively.
