The subject of research is a pool of widgets, which provides a user interface in a computer control system for moving objects. The object of research is the process of information exchange between the components of a computer system, which are directly involved in the control of moving objects. The task of allocating resources for a pool of widgets that provide operational control of moving objects is critical. As the number of elements increases in the pool of widgets, the competition for the resources of the computer system increases significantly, respectively, the queues for the most demanded resources grow. Therefore, it is necessary to reallocate resources between requests in such a way that the priorities of requests are taken into account, and the response time of operational requests does not exceed the standard time. Such distribution cannot be realized without a model that would show the parameters of all information flows between the components, which is the purpose of this article. In doing so, the model must consider the characteristics of the pool of widgets that support the user interface. Research results. To achieve this goal, several particular tasks were solved. First, the main sets were identified that will be involved in modeling information interconnections between software components that service requests for user interface widgets in a computer system environment. Then, a diagram of informational interconnections between these sets was developed. Further, the parameters of the requests, which were initiated by the widgets, of the applications, and the fragments of the widget query service database were determined and formalized. All this made it possible to form a model of information interconnections using a tuple of obtained vectors, sets, and Boolean matrices. In the proposed mathematical model, many limitations are imposed on the elements of this tuple, associated with the characteristic features of the control module for the user interface of the computer system. Besides, the limitations associated with the functioning of the basic network of the computer system are taken into account. In the final model, Boolean matrices affecting resource allocation defined as model variables. A fast algorithm for determining the space of admissible distributions is proposed. Conclusions. The developed mathematical model determines the parameters of information flows between the components of the computer system, which are involved in the control of moving objects. This model will allow for the operational reallocation of resources between requests using the proposed fast algorithm.

Happy Nugrahaning Widhi, Heru Winarno, in paper orchid plant watering system using humidity sensor used Borland Delphi 7 based on arduino uno R3 explain that the utilization of variable moisture for plant watering orchids do not fully utilized. At this time watering orchids is still done manually. It certainly took a lot of time, by making a watering system based on this moisture will save time. To determine the value of temperature and humidity used SHT-11 module is capable of detecting the temperature from -40C to 123,8˚C and relative humidity from 0% RH to 100% RH. Watering plants Phalaenopsis amabilis orchids species do when the SHT-11 detects the humidity inside the orchids house below 60% RH. Watering is carried out by spraying water from above directly into the plant’s roots. The method of watering is intended that the water can be poured directly absorbed by the plant. This control system controlled by arduino uno microcontroller. As for the computer control system, used Borland Delphi 7 to make aplication for control. So this watering system is divided into two they are automated systems and control through computer system Keywords: Module SHT-11, Arduino UNO, Borland Delphi 7.

Hydraulic descaling system is the key device to ensure the surface quality of billet. However, traditional control methods lead to the stability problem in hydraulic descaling system. To solve the problem, the construction of the hydraulic descaling computer control system is studied, the working principle of the system is analyzed, and the high pressure water bench of hydraulic descaling is designed. Based on it, the corresponding computer control software is developed. The application shows that the designed system is stable in practice, which is helpful for enterprise production.
