The operation of a sequencing batch bioreactor is evaluated when high concentration peaks of a toxic compound (4-chlorophenol, 4CP) are introduced into the reactor. A control strategy based on the dissolved oxygen concentration, measured on line, is utilized. To detect the end of the reaction period, the automated system search for the moment when the dissolved oxygen has passed by a minimum, as a consequence of the metabolic activity of the microorganisms and right after to a maximum due to the saturation of the water (similar to the self-cycling fermentation, SCF, strategy). The dissolved oxygen signal was sent to a personal computer via data acquisition and control using MATLAB and the SIMULINK package. The system operating under the automated strategy presented a stable operation when the acclimated microorganisms (to an initial concentration of 350 mg 4CP/L), were exposed to a punctual concentration peaks of 600 mg 4CP/L. The 4CP concentrations peaks superior or equals to 1,050 mg/L only disturbed the system from a short to a medium term (one month). The 1,400 mg/L peak caused a shutdown in the metabolic activity of the microorganisms that led to the reactor failure. The biomass acclimated with the SCF strategy can partially support the variations of the toxic influent since, at the moment in which the influent become inhibitory, there is a failure of the system.

In the course of the study, the activity of Ukrainian enterprises was analyzed. It was revealed that the main aspects that require increased attention, regardless of the industry, are staff management and order management. The activity of any enterprise consists of fulfilling orders and, as a consequence, satisfying customers. It is proposed to develop an automated system that will enable to keep records of orders, namely: the time of order receipt, the number of products, the urgency, the necessary material and time resources, the priority of the order, the executor, the predicted and actual time of the order. This system will help to organize the work of staff, namely: to optimize the working hours of employees due to the dynamic scheduling of the task list; to introduce responsibility for an order that is tied to a specific employee, to keep records of shifts and working hours, automatically form a payroll with due account of worked shifts/hours. The work designed an automated system for managing orders and staff at middle-class enterprises. The requirements for this system are defined and two types of architecture are proposed. For a better understanding of the design phase of the automated system, a class diagram, activity diagram and interaction diagrams are presented. In the process of research, the end product was created with a user-friendly and intuitive user interface that maximally satisfies all the requirements that have been defined for this system. For today the system works in a test mode at the enterprise of Ukraine. The introduction of the system to the filter element manufacturing company allowed to improve the interaction with customers by 40 % due to faster fulfillment of orders; 80 % facilitate the work of managers to track and control the execution of orders; and also, by 20% increase the efficiency of the staff department. What on the whole positively affected the work of the enterprise as a whole.

In this chapter, the author presents the problems of design of the robust automated system for stabilization and control of platforms with aircraft observation equipment. The mathematical model of the triaxial stabilized platform is developed. The procedure of synthesis of robust stabilization system based on robust structural synthesis is represented. The above-mentioned procedure uses loop-shaping approach and method of the mixed sensitivity. The matrix weighting transfer functions are obtained. The optimization programs in MatLab are developed. The developed procedures are approved based on the results of simulation by means of the appropriate Simulink model. The obtained results can be useful for unmanned aerial vehicles and aircraft of special aviation, which are used for monitoring technical objects and aerial photography. The technical contributions are procedures of the robust controller design represented as the flowchart. The proposed approach is validated by application of the theoretical suppositions to the concrete example and appropriate simulation results.

Water is one of the most precious natural resources of the earth, without which the living beings cannot survive. Water is important for the sustenance of human civilization. Man uses water for many purposes like drinking, cleaning, washing, bathing, heating, rearing cattle, and farming. Mankind, for the bettering of themselves and society, advanced towards industries and industrial products. But this progress towards industrialization not only utilizes huge amounts of fresh water, but returns water to the environment with pollutants, which changes its natural quality. Thus, mankind is heading towards misery, instead of comfort. Effective measures need to be taken to prevent, minimize, and control water pollution before it becomes too late.

The development of the intelligent green building project (IGBP) is the pursuit of a business strategy of an enterprise in principle and the launch of the project in practice. The IGBP is integrated with the application of the Project Definition Rating Index (PDRI) in order to combine the needs of pre-project planning. These are the steps to enhance the performance of project execution. The IGBP-PDRI model proposed to construct in this study is based on the life cycle of the engineering to set up different phases of work for process evaluation. The model of evaluation is divided into 4 sections, 11 categories, and 60 elements. Pre-project planning helps to forecast possible risks in the development of the project. In the course of project execution, quality requirement is satisfied through monitoring and control. These help to ensure the operation efficiency of the project, to the extent that the automated system of the building supported by green construction can meet the goal of sustainable development.
