Assessment of the current technical condition of electrical equipment based on an artificial neural network

Assessment of the current technical condition is an important task, so the state of electrical equipment depends on its further operability. Thanks to modern computing devices, it is possible to implement actively artificial intelligence and computer-assisted learning methods that allow achieving high efficiency in data processing. A study was conducted and an algorithm for diagnosing the technical condition based on an artificial neural network was developed. A model based on a multilayer perceptron is proposed, which allows evaluating the technical condition of a high-voltage power transformer. The result of the technical diagnostics of the model is the assignment of the condition to one of the five classes, proposed by the guidelines presented by the International Council on Large Electrical Systems. The methodology is presented on the example of a 250 MVA transformer with a certain defect history, which allowed us to show the reliability and validity of the obtained results. It is shown that the use of the proposed model makes it possible to achieve accuracy in determining the technical condition of 0.95. The introduction of this model into an automated monitoring and diagnostics system will allow assessing the technical condition of electrical equipment in real time with sufficient accuracy.
Offline character recognition in transport logistic tables

The paper proposes the improved skeleton method of handwritten characters recognition, which is based on the filtering procedure and the principle of alternating shading schemes of skeletonized area on the 4- and 8-timeslinked raster. The procedure of high-frequency filtration based on discrete real cosine transformation or discrete complex Fourier transform with automatic selection of filtration parameters makes it possible to significantly improve the image quality of handwritten symbols, in particular, to eliminate in many cases thin bridges between the areas of symbol element representation. The principle of alternating the painting schemes along the 4- and 8-timeslinked raster makes it possible to get the wave front of the skeletonized area close to a circle. In this case, the broken lines representing the branches of the skeleton graphs retain the shapes of the symbols. Numerical experiments on the construction of skeleton sets and skeleton graphs for recognizable handwritten symbols located in the cells of the tables of logistic transport problems have been performed. Software implementation of the method is proposed.
Digital models of parametric structures

Formation of parametric structure digital model are considered. Investigation was based on the analysis of the shaping evolution of the analytical surface in the form of a hyperboloid of rotation. Finite element frame represents a spatial plate-rod system has been developed during creation of the digital model. This scheme allows to study the effectiveness of constructive solutions under dynamic influence at the design stage. Dynamic characteristics of various design solutions are considered in process of choosing a rational variant of the building frame. The influence of the inclusion of outrigger floor in the model of the frame at various levels of the building are investigated. The proposed method of research and application of the possibilities of the shaping evolution allows to proceed to the modernization of BIM technologies in the design of unique buildings. Recommendations for refining the algorithm for studying parametric object digital models were developed.
The use of fuzzy sets to determine the parameters of genetic algorithms that provide approximately the same execution time on the CPU and GPU

The problem under consideration consists in choosing the number of k individuals, so that the time for processing k individuals by the genetic algorithm (GA) on the CPU architecture is close to the time for processing l individuals on the GPU architecture by the genetic algorithm. The initial information is data arrays containing information about the processing time of a given number of individuals by the genetic algorithm on the available hardware architectures. Fuzzy numbers are determined based on these arrays? ~? and? ~? , describing the processing time of a given number of individuals, respectively, on the CPU and GPU architectures. The peculiarities of the subject area do not allow considering the well-known methods of comparison based on the equalities of the membership functions and the nearest clear sets as adequate. Based on the known formula “close to Y (around Y)” the way to compare fuzzy numbers? ~? and? ~? was developed in order to determine the degree of closeness of the processing time of k and l individuals, respectively, on the hardware architectures of the CPU and GPU.
AN ANALYSIS OF WORK AND NON-WORK PATTERNS IN MALAYSIAN PUBLIC SECTOR WORKPLACES: A MULTI-LEVEL APPROACH

This research examines the relationship between the work and non-work lives of Malaysian public sector employees. The study sought to analyse how the interface between work and non-work life is influenced by both organisational contexts as well as the broader social and cultural context of Malaysia. As the research in the context have been under-investigated and the research subject usually adopts a single-level of analysis, therefore, this study is based on a multi-level analysis examining the interaction between the macro level (role of the State), meso level (the role of the organisations), with micro level influences (such as the individual‟s religious and cultural values) and how, in turn, these factors affect the ways in which employees organise their work and non-work lives. The research is conducted in three organisations and includes 71 in-depth interviews. Each organisation chosen reflected different workforce compositions in terms of gender, ethnicity, age and religious backgrounds. A multi-level perspective demonstrates how structural factors are significant when examining how actors are either enabled or constrained in their ability to manage the relationship between work and non-work. The findings of this study demonstrate that the State, organisations (through their different working practices, working hours and organisational cultures), religious and cultural values as well as the range of familial, communal and institutional supports influence how employees organise their work and non-working lives. Within the Malaysian context, religious and cultural values emphasise the dual commitment of work and non-work lives for employees. Thus, the study highlights how this context affects management‟s decisions and employees‟ expectations and experiences. This study also found that work/non-work life approaches vary at the meso level because of different organisational contexts. Finally, the nature of the relationship between work and non-work varies according to the strategies which workers adopt. Variations of work/non-work integration identified among workers in the study demonstrates that some achieve partial to full integration, whereas others either experience conflictual relations between work and home, or develop strategies to segment work and non-work. Thus, the study identified different degrees of satisfaction and dis-satisfaction with the relationship between work and non-work. Hence, work/non-work integration can be best viewed as a continuum. A multi-level examination of macro-, meso- and micro levels can provide critical learning points for policy makers and employers aware of the need to find culturally appropriate ways to enhance work/non-work integration as well as to alleviate the harmful effects of work/non-work conflict.
A 60 GHz eight-element phased-array receiver front-end in 0.25 µm SiGe BiCMOS technology

This paper presents the design of an eight-element 60 GHz phased-array receiver chip with interference mitigation capability, fabricated in 0.25 μm SiGe BiCMOS technology. Each receiver element contains a low noise amplifier (LNA) and a vector-modulator that supports high-resolution amplitude and phase control. A fully differential power combining network follows the eight elements. The chip also includes an active power divider, a down conversion mixer, and fully integrated 48 GHz PLL to demonstrate the IF down-conversion. With LNA, a phase shifter and hybrid active and passive power combining network, each receiver path achieves 18 dB of gain, 360° phase shift in steps less than 3°, 20 dB amplitude control, and 4 GHz 3 dB-bandwidth and input referred 1 dB compression point P1 dB of each element is of −22 dBm. Each receiver element dissipates in total 132 mW. The phased-array receiver shows more than 25 dB of signal to interference noise ratio, by means of amplitude and phase control.
Spreading resistance between constant potential surfaces

We determine the spreading resistance for a sheet of homogeneous material of uniform thickness with a disk contact source on one side and with current collected (i) over the entire back plane, and (ii) at a corresponding disk on the back plane. A constant driving potential is assumed over the source resulting in mixed boundary conditions in the plane of the source. For each case, a closed form integral solution is derived and then numerically integrated for a range of geometric ratios resulting in a universal spreading resistance curve. The results are used to evaluate the spreading resistances encountered in a typical (1 Ω cm) semiconductor material.

Normalized Model of Traffic Light Traits Based on Colored Pixels

Nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent control systems to improve driving safety and health has become a necessity. To design and implement such control systems, having information about traffic light colors is essential. There are the wide variety of traffic lights in terms of light intensity and color. Therefore it seems that design and practical implementation of these systems with acceptable performance is difficult. The study has been discussed extracting, Categories and the offer of a specific model for color and intensity of traffic signals based on an improved algorithm. The proposed intelligent system will detect traffic lights through images by installing camera instead of using electronic sensors. After capturing, the image sequence will then be analyzed using computer based programs for extracting of lights specifications.

Pipe Index Vector: A Method to Improve Genetic-Algorithm-Based Pipe Optimization

This paper proposes a methodology for the optimal design of water distribution systems based on genetic algorithms. The objective of the optimization is to minimize the capital cost, subject to ensuring adequate pressures at all nodes during peak demands. The proposed method is novel in that it involves the use of a pipe index vector to control the genetic algorithm search. The pipe index vector is a measure of the relative importance of pipes in a network in terms of their impact on the hydraulic performance of the network. By using the pipe index vector it is possible to exclude regions of the search space where impractical and infeasible solutions exist. By reducing the search space it is possible to generate feasible solutions more quickly and hence process much healthier populations than would be the case in a standard genetic algorithm. This results in optimal solutions being found in a fewer number of generations resulting in a substantial saving in terms of computational time. The method has been tested on several networks, including networks used for benchmark testing least cost design algorithms, and has been shown to be efficient and robust.

The Relationship Between Racial/Ethnic Concordance and Hypertension Control.

INTRODUCTION Given the increasing impact of the healthcare cost of hypertension on the economy, understanding the control of high blood pressure is warranted, particularly as it pertains to racial/ethnic disparities in hypertension control. OBJECTIVE To understand the relationship between hypertension control and racial/ethnic concordance, we investigated whether the racial/ethnic concordance between a patient's race/ethnicity and that of the individual's provider is a predictor of high blood pressure control. METHODS Data was collected for 612,524 patients from Kaiser Permanente Southern California who were at least 18 year old and received a diagnosis of hypertension between January 1, 2016 and December 31, 2019. A multiple regression analysis was carried out to assess the correlation between hypertension control and patient-provider concordance. RESULTS The independent variables proxying for patient-provider relationship are positive and statistically significant at the 5% level. Out of the 3 types of concordance, language has the highest standardized estimate, followed by gender and race. DISCUSSION We found correlations between racial/ethnic patient-provider concordance and hypertension control. Consistent with previous studies, we found that Asian patients experience more time in hypertension control. By contrast, Black and Hispanic patients have less time in hypertension control. Having the same primary care provider for a longer span of time is also positively correlated with length of hypertension control. CONCLUSION Correlation between racial/ethnic concordance, length of time under the primary provider's care, and length of time spent in hypertension control suggests that the patient-provider relationship remains a critical component of health outcomes.
HAZARD QUOTIENT FOR INTAKE OF IRON, MANGANESE AND COPPER THROUGH CONSUMPTION OF SPINACH AS INFLUENCED BY APPLIED ZN AND ORGANICS

Zinc (Zn), Iron, Manganese and Copper is one of the most important micronutrients for humans. Human health is adversely affected by its deficiency. At the same time, excessive intake of these cationic micronutrient may cause several physiological diseases and dis-orders. In this context, risk to human health for intake of Fe, Mn, Cu and Zn-enriched Palak (Spinacea oleracea L.) was assessed in terms of hazard quotient (HQ). In a pot culture experiment, spinach crop was grown on soil treated with four levels of Zn (0, 5, 20 and 40 mg kg) and three levels of organics (control, 3% farmyard manure and 3% poultry manure). Results indicated that The values of HQ for intake of Fe through consumption of Palak (first cutting) a mean value of 0.24. The corresponding values for second cutting of Palak a mean 0.23. The values of HQ for intake of Mn a mean value of 0.16 in first cutting of Palak. In second cutting, an average value of 0.20. The concentration of Cu in Palak ranged from 16.44 to 23.66 (mean value 19.76 mg kg) and 17.7 to 29.13 mg kg (mean value 22.9 mg kg) for first and second cutting, respectively By and large, this enriched vegetable was safe to be consumed by human as far as their Fe, Mn and Cu contents were concerned.

Implications of salinity normalization of seawater total alkalinity in coral reef metabolism studies

Salinity normalization of total alkalinity (TA) and dissolved inorganic carbon (DIC) data is commonly used to account for conservative mixing processes when inferring net metabolic modification of seawater by coral reefs. Salinity (S), TA, and DIC can be accurately and precisely measured, but salinity normalization of TA (nTA) and DIC (nDIC) can generate considerable and unrecognized uncertainties in coral reef metabolic rate estimates. While salinity normalization errors apply to nTA, nDIC, and other ions of interest in coral reefs, here, we focus on nTA due to its application as a proxy for net coral reef calcification and the importance for reefs to maintain calcium carbonate production under environmental change. We used global datasets of coral reef TA, S, and modeled groundwater discharge to assess the effect of different volumetric ratios of multiple freshwater TA inputs (i.e., groundwater, river, surface runoff, and precipitation) on nTA. Coral reef freshwater endmember TA ranged from -2 up to 3032 μmol/kg in hypothetical reef locations with freshwater inputs dominated by riverine, surface runoff, or precipitation mixing with groundwater. The upper bound of freshwater TA in these scenarios can result in an uncertainty in reef TA of up to 90 μmol/kg per unit S normalization if the freshwater endmember is erroneously assumed to have 0 μmol/kg alkalinity. The uncertainty associated with S normalization can, under some circumstances, even shift the interpretation of whether reefs are net calcifying to net dissolving, or vice versa. Moreover, the choice of reference salinity for normalization implicitly makes assumptions about whether biogeochemical processes occur before or after mixing between different water masses, which can add uncertainties of ±1.4% nTA per unit S normalization. Additional considerations in identifying potential freshwater sources of TA and their relative volumetric impact on seawater are required to reduce uncertainties associated with S normalization of coral reef carbonate chemistry data in some environments. However, at a minimum, researchers should minimize the range of salinities over which the normalization is applied, precisely measure salinity, and normalize TA values to a carefully selected reference salinity that takes local factors into account.
