Voltage source inverter (VSI) plays an important roles in electrical drive systems. Consistently, expose to hash environmental condition, the lifespan of the electronic component such as insulated-gate bipolar transistor (IGBT) may shorten and many faults related to the inverter especially switches can be occur. The present of VSI switches faults causing equipment failure and increased the cost of manufacturing process. Therefore, faults detection analysis is mandatory to identify the VSI switches faults. This paper presents the analysis of VSI switches faults using time-frequency distributions (TFDs) which are short times Fourier transform (STFT) and spectrogram. From time-frequency representation (TFR) obtained by using the TFDs, parameters of the faults signal are estimated such as instantaneous of average, root mean square (RMS), fundamental, Total Waveform Distortion (TWD), Total Harmonics Distortion (THD) and Total non-Harmonic Distortion (TnHD) of current signals. Then, based on the characteristics of the faults calculated from the signal parameters, VSI switches faults can be detected and identified. The performance of TFD for the faults analysis is also demonstrated to obtain the best TFD for switches faults detection and identification system. The results show that, STFT is the best technique to classify and identify VSI switches faults and can be implemented for automated system.

The paper is devoted to the issues related to the development and use of automated assessment systems for programming tasks. The work on automated testing of programming tasks had been held in Novosibirsk State University since 1998. It was created several generations of systems of this type. The first program of about 1,000 lines was written in Perl. Currently, the automated system, named NSUts, is used in the programming contests and in the educational process. As a result of work in it, as well as acquaintance with other similar systems, both Russian and foreign, it was possible to formulate requirements for software development of this kind, to analyze the difference between the systems for testing competitions and training support systems. The article also provides an overview of the existing systems for checking tasks on programming, an analysis of the advantages and disadvantages of each of these systems, and a detailed comparison of the NSUts system with the Yandex Contest system. The current state of the NSUts system architecture is described. Much attention is paid to the practice of using the system in the educational process, statistics and graphs of students' progress of students studying with the help of this system are given. The article describes the analysis of the experience of using the NSUts system and outlines the prospects for its development.

The potential clinical application of gas chromatography to microbial identifcation was evaluated. A completely automated system, the MIS (Microbial Identification System; Hewlett- Packard) can analyse and identify pure strains by comparison of their cellular fatty acids patterns (C9-C20) with the reference parameters stored in a library. Three hundred and sixty-seven strains were tested, comparing the gas chromatographic results with those obtained by the traditional microbiological methods in the bacteriology laboratory of our Institute. A standardized extractive procedure was followed to obtain the fatty acid methyl esters (FAMEs), but some modifications to the recommended procedure were introduced in the bacterial growth procedures: colonies harvested not only from the recommended growth media but also from selective media routinely used in the bacteriology laboratory were successfully examined. These modifications did not influence the results but improved the ease for the user; good agreement with the comparison method was observed as far as identifications of genus and species are concerned for 238 cases. The major advantages of this computerized system are a reduction in the time required to obtain the final results, the elimination of human errors by using the autosampler and a better inter-laboratory comparability of results owing to a higher degree of objectivity. On the other hand, the limited throughput of MIS (only 40 samples in 24 h) prevents its use in a large routine laboratory; this technology is appropriate in emergency cases, in taxonomic studies and as a confirmatory method.

Objective: Enterococci are among the important microorganism group worldwide due to their natural resistance to many antibiotics, especially their acquired resistance mechanisms against glycopeptides (vancomycin, teicoplanin). In this study, vancomycin and teicoplanin resistance were phenotypically determined in Vancomycin-resistant Enterococci strains obtained from various clinical specimens, and the presence of VanA, VanB and VanC was investigated by molecular methods. Method: A total of 30 VRE strains isolated from various clinical specimens at Microbiology Laboratory of Van Yuzuncu Yil University Faculty of Medicine Hospital between 2015 and 2018 were included in the study. MicroScan WalkAway 96 Plus (Beckman Coulter, USA) automated system was used for the identification of strains and determination of antibiotic resistance. Antimicrobial resistance to vancomycin and teicoplanin were also determined by gradient test method. Resistance genes were investigated by in-house PCR method performed in Inonu University Faculty of Medicine, Molecular Diagnostics Laboratory of The Department of Medical Microbiology using appropriate primers. Results: Identification tests revealed 29 strains as Enterococcus faecium and 1 as Enterococcus faecalis. While all strains were resistant to vancomycin and teicoplanin in the automated identification system, three isolates tested by gradient test method were found to be susceptible to these antibiotics. Molecular method of these three strains showed that there were no VanA, VanB and VanC genes. While VanA gene was detected in 27 strains, VanB gene was detected in one strain, and VanC gene was not detected. Resistance detection by gradient test and molecular method were found to be 100% compatible in the identification of vancomycinresistance in enterococci isolates. Conclusion: Gradient test method is reliable in determining glycopeptide resistance of enterococcal isolates in clinical microbiology laboratory.

Citizen science is essential for nationwide ecological surveys of species distribution. While the accuracy of the information collected by beginner participants is not guaranteed, it is important to develop an automated system to assist species identification. Deep learning techniques for image recognition have been successfully applied in many fields and may contribute to species identification. However, deep learning techniques have not been utilized in ecological surveys of citizen science, because they require the collection of a large number of images, which is time-consuming and labor-intensive. To counter these issues, we propose a simple and effective strategy to construct species identification systems using fewer images. As an example, we collected 4,571 images of 204 species of Japanese dragonflies and damselflies from open-access websites (i.e., web scraping) and scanned 4,005 images from books and specimens for species identification. In addition, we obtained field occurrence records (i.e., range of distribution) of all species of dragonflies and damselflies from the National Biodiversity Center, Japan. Using the images and records, we developed a species identification system for Japanese dragonflies and damselflies. We validated that the accuracy of the species identification system was improved by combining web-scraped and scanned images; the top-1 accuracy of the system was 0.324 when trained using only web-scraped images, whereas it improved to 0.546 when trained using both web-scraped and scanned images. In addition, the combination of images and field occurrence records further improved the top-1 accuracy to 0.668. The values of top-3 accuracy under the three conditions were 0.565, 0.768, and 0.873, respectively. Thus, combining images with field occurrence records markedly improved the accuracy of the species identification system. The strategy of species identification proposed in this study can be applied to any group of organisms. Furthermore, it has the potential to strike a balance between continuously recruiting beginner participants and updating the data accuracy of citizen science.

Robotics is often viewed as a complex high-tech area that can be applied to improve productivity but only at a high cost to the organization. Contrary to this frame of mind, robotic applications can be implemented by average-sized organizations at a relatively low cost with low complexity. As part of the senior design project activities at Lake Superior State University, an automotive parts supplier submitted a project involving the redesign of a manual machine tending process. The company, which manufactures tie rods, has a process where an operator tediously loads and unloads tie rods to and from two machines in a dirty and dangerous environment. A flexible system to automate the machine loading process was considered and will be proposed. The flexible automated system will include a parts feeder for orienting the tie rods into a single position and a robot for picking and placing the tie rods into the machines. The end-of-arm tooling for the robot and the parts feeder will be designed to handle different varieties of tie rods. The automated system flexibility will allow the robot, which will be mounted on a track, to be conveniently re-positioned away from the machines when needed. By doing so, the machines can be run in the manual mode for unusual tie rod part varieties using an operator to tend the machines. In addition to presenting an uncomplicated robotics solution to the problem, this paper will show that by incorporating the proposed automation ideas, the hardware costs to implement the flexible robotics system will be under $100,000. This is a relatively low cost for an average-sized company, considering automation.

The article includes modeling of the automated system of personnel time recording with further development and implementation of it in the educational institution. Practice shows that when using automated time recording, more effective personnel management occurs, employee discipline is increased, and the wage fund is saved on 5–15%. Personalized personnel identification methods have been identified; the selection of technical equipment and software for data collection is justified; A work time model has been developed; Software for employee identification, recording and recording of working hours has been developed and introduced. To do this, special access control equipment was installed on the passageway. Employees have special cards that allow them to easily overcome these devices. If there are several checkpoints in the territory, it is advisable to use a computer network to transfer data to the server, where all data about employees are stored. Based on such data, accurate reports of misconduct can be generated, as well as a time sheet. User identification is an integral and important element for any information system. The identification system is one of the key elements of the infrastructure for protection against unauthorized access. The task of identification and authorization systems is to determine and verify the set of authority of the subject when accessing the information system. A barcode can also act as a unique person identifier. Each employee is ssued a card with a unique bar code, this code is fixed to the person in the database. A barcode scanner is installed on each pass point. This model with a developed algorithm for identifying a person and fixing the passage of control was ntroduced at the Kherson Polytechnic Vocational College of Odessa Polytechnic State University.

Background. Breast conservation therapy (BCT) is the standard treatment for breast cancer; however, 32–63% of procedures have a positive margin leading to secondary procedures. The standard of care to evaluate surgical margins is based on permanent section. Imprint cytology (IC) has been used to evaluate surgical samples but is limited by excessive cauterization thus requiring experienced cytopathologist for interpretation. An automated image screening process has been developed to detect cancerous cells from IC on cauterized margins. Methods. IC was prospectively performed on margins during lumpectomy operations for breast cancer in addition to permanent section on 127 patients. An 8-slide training subset and 8-slide testing subset were culled. H&E IC automated analysis, based on linear discriminant analysis, was compared to manual pathologist interpretation. Results. The most important descriptors, from highest to lowest performance, are nucleus color (23%), cytoplasm color (15%), shape (12%), grey intensity (9%), and local area (5%). There was 100% agreement between automated and manual interpretation of IC slides. Conclusion. Although limited by IC sampling variability, an automated system for accurate IC cancer cell identification system is demonstrated, with high correlation to manual analysis, even in the face of cauterization effects which supplement permanent section analysis.
