Investigating the discrepancy between MAIA and MP-1 microperimetry results.

Previous work has suggested that sensitivities measured on the iCare MAIA and Nidek MP-1microperimeters differ systematically, although it is unclear whether one or both devices are inaccurate. Here, we assess the discrepancy between these two instruments as well as with a rigorous reference standard. Fifteen healthy participants underwent visual field testing on the MAIA and MP-1microperimeters. Results were compared to a reference measure of increment thresholds on a laboratory-based, calibrated computer monitor system using the same background luminance and target size. Discrepancies were assessed as a function of eccentricity along the vertical meridian. Differences in decibels (dB) due to differences in the maximum stimulus luminance between devices were accounted for mathematically. The mean sensitivity measured with the MAIA was <1dB lower than laboratory-based measures, which was statistically significant but of limited clinical importance. In contrast, the mean sensitivity measured with the MP-1 was >8dB lower than the laboratory measures. The difference was greater for an eccentric superior retinal location, in contrast to what would be predicted if the discrepancy was due to a ceiling effect caused by the MP-1's limited dynamic range. While MAIA measurements showed low bias compared with our rigorously determined reference standard, the MP-1showed large discrepancies that could not be explained purely by the limited dynamic range of the instrument. MAIA and MP-1sensitivity values cannot be compared directly, and caution is advised when assessing absolute sensitivities or eccentricity effects in the extensive MP-1literature.

Applying Computational Fluid Dynamics in the Development of Smart Ripening Rooms for Traditional Cheeses.

Traditional ewe’s cheese producers face certain challenges caused by fluctuating environmental parameters inside the ripening room, which lead to lack of homogeneity in the final product. The present research discusses the application of computer fluid dynamics for simulating the distribution of environmental parameters, predicting the airflow pattern, and identifying critical areas where such parameters could cause reduced cheese quality. A new monitoring system was developed including presence sensors, temperature and humidity dataloggers, pneumatic actuators, microcontrollers, and microcomputers connected remotely for control, data visualization, and processing. The validation of the computer simulation and monitoring system was made with a batch of 40 ewe’s cheeses distributed in three different zones inside a prototype ripening room and ripened for 35 days. At 35 days, a physical, chemical, and microbiological characterization of cheeses was made for evaluation of the influence of environmental conditions on cheese quality. The comparison between simulated and local measurements showed close agreement, especially concerning air velocity inside the stacks of cheese. The results of Pearson’s correlation analysis and PCA concluded that temperature affected the appearance of the rind, hardness, number and area occupied by holes. Humidity affected aw and mFeret. Air velocity affected pH and the circularity of gas holes.

System Monitoring Addon Analysis in System Load Simulation

The complexity of interconnected devices requires constant real-time monitoring, as failure of one part can have catastrophic consequences for the entire system. Computer-information monitoring tools enable us to always be one step ahead of potential problems that may occur in a monitored network environment, whether it is a human-caused configuration or simply an element has failed or stopped working. Not only can they report potential problems, but they can also solve the problem itself. For example, if an element needs increased resources at a given time, the tool itself can recognize it and automatically increase the resource needs of that element. By setting up a monitoring system in a virtual environment, the results can be seen and through their analysis will bring an optimal solution when it comes to what agent to use. This paper presents analysis of how network monitoring agent is responding in cases when there is increased use of shared resources. Knowing this can help in choosing what agent should be used in any given environment, and with that more resources will be saved. This leads to better utilization of resources which is an important in mid-size and big setup of computer monitoring systems.

КОМП'ЮТЕРНА СИСТЕМА МОНІТОРИНГУ ЗАЛИШКОВОГО РЕСУРСУ ОБЛАДНАННЯ ШИРОКОШТАБОВОГО СТАНА

The purpose of the work is to develop a computer system for calculating and optimizing the hot rolling modes of the headquarters, forecasting and increasing the residual life of rolling mill equipment. It is shown that in recent years there has been a steady increase in the production of hot-rolled staffs of high-strength steels and especially thin staffs. Mastering the production of such strips leads to an increase in the load on the equipment of rolling mills. The result is increased wear of equipment elements and their premature failure. The Institute of Ferrous Metallurgy of the National Academy of Sciences of Ukraine has developed a computer system for online monitoring of the residual resource of the wide strip hot rolling mill. The main functions of the computer system are: adaptation of models of power parameters of the rolling process; verification of models according to the actual assortment; calculations of power parameters according to adapted models; optimization of rolling modes to ensure the allowable values of power parameters of rolling and the target temperature of completion of rolling, the maximum productivity of the mill; calculations of the number of load cycles of elements in the equipment of the mill; estimation of the residual resource of the equipment taking into account its initial values. The following schematization methods were chosen for the design of the residual resource forecasting system: for dynamic loads - the method of allocation of complete cycles, for static loads - the method of extremes. All objects of the drive line which are diagnosed are divided into three classes: details which can be both separately, and as a part of knots or units; units that can be both separately and as part of units; units consisting of parts and assemblies. The calculation of the residual resource is performed only for details. The residual life of the node or unit is determined by the part that is part of it and has the smallest residual life. The developed computer system was tested on one of the existing hot strip mills. To do this, the transfer of source data contained in industrial databases to the developed computer system for monitoring the residual resource was established. The test showed a fairly high reliability of forecasting the power parameters of the rolling headquarters and the assessment of the residual life of the equipment and the drive line of the rolls of the working stands.

The common features of the single‐chip microcomputer are wireless, huge low power consumption, and simple development. Engineering practice shows that the designed system is relatively good in terms of reliability and stability of data transmission; even in the case of severe noise interference and electromagnetic interference, the probability of network nodes malfunctioning is still very small. The router node processes and analyzes the collected motion data, calculates the energy consumption and motion state of human motion based on the acceleration value of each axis and extracts data characteristics, and transmits the obtained results to the coordinator for real‐time display.

Information and search space for monitoring the machine and tractor fleet

The machine and tractor fleet of agricultural enterprises is a set of objects of agricultural machinery linked in technological chains, spread over the area of agricultural land. For effective use of the park, it is necessary to monitor it in order to maintain or restore its working condition in a timely manner through the implementation of repair and maintenance actions.
