Future Management

Management of escapements can be formulated as a problem in stochastic optimal control. Using the Ricker model as a reasonable representation of the average stock–recruit relationship, approximate optimal policies are found for cases where there is parameter uncertainty as well as environmental variation, by employing a "wide-sense adaptive dual control" algorithm. This algorithm accounts for the future information value of any escapement choice as well as the effect on immediate yield. The algorithm indicates that escapements should be deliberately varied to obtain better information for future management, provided that historical escapement levels have not been extremely variable. Such actively adaptive, or probing policies will become progressively more important in the future as managers learn how to control escapements more precisely and thus eliminate natural sources of informative variation.Key words: adaptive management, stock–recruitment, escapement

Inherent Problem

Automation of process control in chemical plant is an inspiring application field of mechatronicengineering. In order to understand the complexity of the automation and its application requireknowledges of chemical engineering, mechatronic and other numerous interconnected studies.The background of this paper is an inherent problem of overheating due to lack of level controlsystem. The objective of this research is to control the dynamic process of desired level more tightlywhich is able to stabilize raw material supply into the chemical plant system.The chemical plant is operated within a wide range of feed compositions and flow rates whichmake the process control become difficult. This research uses modelling for efficiency reason andanalyzes the model by PID control algorithm along with its simulations by using Matlab.

And Function

Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and function. In higher plants, such as in animals, the intercellular communication is fulfilled through chemical messengers. These specific compounds in plants are called phytohormones, or in a wide sense, bioregulators. Even a small quantity of these endogenous organic compounds are able to regulate the operation, growth and development of higher plants, and keep the connection between cells, tissues and synergy beween organs. Since they do not have nervous and immume systems, phytohormones play essential role in plants’ life. Orv. Hetil., 2014, 155(26), 1011–1018.
