<p>This is a reissue of a paper which appeared in ACTA IMEKO 1967, Proceedings of the 4th International Measurement Congress, 1967, Warsaw, vol. 1, pp. 37-50.</p> <p>The paper sets a frame on the role of measurement and control as critical tools to support the automation of manufacturing processes. In this perspective three main requirements for measurement are discussed, i.e., to identify where automation can be most profitably used; to investigate individual process behaviors and hence to formulate process control strategies; and finally to perform quality control of products.</p>

Abstract Based on discussions in workshop sessions, several recurring themes became evident with respect to the optimization and control of petroleum refinery wastewater treatment systems to achieve effective removal of toxic contaminants. It was apparent that statistical process control (SPC) techniques are finding more widespread use and have been found to be effective. However, the implementation of real-time process control strategies in petroleum refinery wastewater treatment systems is in its infancy. Considerable effort will need to be expended to demonstrate the practicality of on-line sensors, and the utility of automated process control in petroleum refinery wastewater treatment systems. This paper provides a summary of the discussions held at the workshop.

According to Chinese traditional classification, large-sized jackets weight over 10,000 tons and stand in over 100-meter water. Large-sized jackets are different from the normal in construction tonnage, structural dimension and quality control requirements as well as construction difficulty. More complicated construction technology and programme, higher grade of materials, stricter control requirements on node weld and higher risks all need matched stricter, more meticulous and more comprehensive management in planning and scheduling. Combined with construction of LW3-1 deep-water jacket, this paper describes the planning, tracking progress, process control and optimization.

Cotton fiber moisture content is one of the most important factors that affects the operation of the cotton ginning process. A system has been developed that measures cotton’s dielectric constant and density with sufficient accuracy to indicate moisture content of the fiber during processing. An electronic capacitor and a pneumatic density sensor supply measurements to a microprocessor which combines them into a predicted moisture content. Tests showed that these predicted readings are more precise than conventional oven-moisture determinations and that they can be used for process control in the ranges from 6.5- to 12-percent moisture content.

Статья посвящена истории связи между развитием исторической науки и политической практики в России. В контексте этого развития представлены, с одной стороны, эволюция исторических исследований и их координации и, с другой стороны, трансформация подхода институциональных структур государства к выбору управленческой стратегии в руководстве работой историков. В качестве примера для исследования обозначенной проблемы выбран период с начала XVIII до начала XXI века, потому что в его рамках была сформирована практика профессиональной деятельности в сфере историографии как процесса человеческой деятельности. Особое внимание в статье адресовано к роли идеологии в формировании различных моделей связи между работой историков и политических деятелей по конструированию образа прошлого, настоящего и будущего развития российской истории. The article reveals the connection between the historical science development and evolution of political practice in Russia.In that context shown are the course of the historical research and the coordination and control strategies implemented by the state, including institutional transformations.As a subject of current research was taken the period from the XVIII – beginning of the XXI centuries, when historiography became a profession and was institutionalized.Special attention is driven to the role of ideology in adopting different models of interaction between historians and political actors, while framing the image of the past, the present and the future of Russia.

This paper investigates the role of trust and control in networks of small and medium-sized enterprises (SMEs), with a focus on both their direct and interaction effects on value creation. To delve into the interplay between trust and control, we unpack control mechanisms into three different forms: output, process, and social control. Our hypotheses are tested on a sample of 58 Italian SME networks based on formal agreements. Results show that the competitiveness and sustainability of inter-firm networks require trust-based relationships among entrepreneurs. Additionally, the adoption of output control mechanisms reinforces the positive link between trust and value creation, whereas a substitution effect exists between trust and process control and, with limited significance, between trust and social control.

AbstractAn overview of current thermal challenges in transport electrification is introduced in order to underpin the research developments and trends of recent thermal management techniques. Currently, explorations of intelligent thermal management and control strategies prevail among car manufacturers in the context of climate change and global warming impacts. Therefore, major cutting-edge systematic approaches in electrified powertrain are summarized in the first place. In particular, the important role of heating, ventilation and air-condition system (HVAC) is emphasised. The trends in developing efficient HVAC system for future electrified powertrain are analysed. Then electric machine efficiency is under spotlight which could be improved by introducing new thermal management techniques and strengthening the efforts of driveline integrations. The demanded integration efforts are expected to provide better value per volume, or more power output/torque per unit with smaller form factor. Driven by demands, major thermal issues of high-power density machines are raised including the comprehensive understanding of thermal path, and multiphysics challenges are addressed whilst embedding power electronic semiconductors, non-isotropic electromagnetic materials and thermal insulation materials. Last but not least, the present review has listed several typical cooling techniques such as liquid cooling jacket, impingement/spray cooling and immersion cooling that could be applied to facilitate the development of integrated electric machine, and a mechanic-electric-thermal holistic approach is suggested at early design phase. Conclusively, a brief summary of the emerging new cooling techniques is presented and the keys to a successful integration are concluded.

To ensure correctly operating control systems, the measurement and control equipment in WWTPs must be mutually consistent. The dynamic simulation of activated sludge systems could offer a suitable tool for designing and optimising control strategies. Ideal or simplified sensor models represent a limiting factor for comparability with field applications. More realistic sensor models are therefore required. Two groups of sensor models are proposed on the basis of field and laboratory tests: one for specific sensors and another for a classification of sensor types to be used with the COST simulation benchmark environment. This should lead to a more realistic test environment and allow control engineers to define the requirements of the measuring equipment as a function of the selected control strategy.
