While tracking has recently evolved to digital with certain limitations, scheduling is limited to expertise of the operator and is applicable up to a short horizon. Dependence on operator-expertise further extends to ladle furnace operation where lift temperature for desired superheat, a complex feature of several parameters, is decided by operator based on heat loss estimation and ladle history.Current work is a step towards digitalization of steel melt shop by minimizing the human involvement in tracking of ladle, scheduling of ladle movement and prediction of lift temperature. A novel technique is introduced for tracking of ladle in melt shop. Based on the ladle tracking and production planning, ladle transport across various units including assignment of appropriate cranes is automated. Finally, a mathematical model is developed to predict the temperature for ladle lifting to ensure desired superheat at caster and has been validated against industrial measurements.With efficient tracking, the visibility of ladles in the melt shop is improved to nearly 100%. With improved scheduling, idle time of ladles and processing units is reduced. Lastly, the numerical thermal model reduces the energy requirements, lowers the idle time and improves casting speed. This improves the overall productivity of the melt shop. With higher level of automation and model-based decision making, dependence on human expertise is reduced and safety of melt shop is improved.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122272762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The economy has a wide range of indicators that are monitored and recorded by governments and international organizations. Agriculture is one of the most essential factors to modern day economical sustainability. The Food and Agriculture Organization keeps essential agricultural data sets which consist of records on production of crops and other agricultural products whose production strongly relates to the Gross Domestic Product of many countries. Assuming that total crop production and agricultural economy growth are highly related, the production of crops and total value of income from agriculture can be learnt by machine learning models. As data is recorded along an axis of time, it can be interpreted as a time series of various factors. Recurrent Neural Network excel in learning time series and sequential data. This paper presents experimental results on training various recurrent neural networks for modeling the changes of Agricultural and Gross Domestic Products. The paper details the data transformation, model building and model validation steps. Our experimental results showed that the models could achieve 85% accuracy.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132349065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the VDE compression method words are stored in the so called compression dictionary, therefore the base unit of the boundary value pattern is the word. The application of VDE is reasonable over patterns where the relatively long base fragments are recurring with short deviance at the end. In our earlier work we found and proved the existence of the pattern which results the best compression ratio. However, determination of the input pattern, which results the worst compression ratio (or worst case), is much more complicated, since it depends on the recursive extension of words.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114378295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Keystroke dynamics has been pointed out as a practical behavioral biometric feature that does not require any additional device for scale up user authentication. The input data of an authentication system based on keystroke dynamics are the typing times on the keyboard. Given that typing times result in time vectors, and these must be compared to see the similarities between them to validate the user. Algorithms of dynamic authentication can be divided into three major groups: estimation of metric distances, statistical methods and machine learning. The paper aims to analyze the possibilities of increasing the efficiency of an authentication algorithm based on keystroke dynamics, in the sense of reducing the value of the Equal Error Rate (EER). The distance method is used to calculate the similarity between users. The paper (1) analyzes the optimal number of di-graphs, (2) analyzes the optimal time combinations generated by a di-graph to be used and, finally, (3) analyzes the possibility of modify the distance calculation metric. These analyzes aim to reduce the error rate generated by an authentication system based on free-text keystroke dynamics. The authors propose a modification of the Manhattan distance calculation formula that generates better performances, EER was improved by 38.53%. The EER value obtained from the modified metrics is 3.27%, compared to 5.32% obtained with the classic Manhattan formula.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128646098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The irregularities presented by the machined surfaces of some workpieces characterize their roughness and are highlighted either by their texture or by their appearance. Cutting parameters, i.e. speed, feed rate and cutting depth can induce vibrations in the cutting tool whose traces left on the surface of the machined part influence their quality.The use of the Finite Element Method (FEM) in the Modal Analysis (MA) of the behavior of a cutting tool offers the possibility to determine the shape of the natural vibration modes and the corresponding natural frequencies. This paper presents the use of Laser Doppler Vibrometry (LDV) for the experimental determination of the modal parameters of a cutting instrument following the analysis of free vibrations resulting from the application of a short-term mechanical impulse. The processing of the signals acquired through LDV was done applying the Prony Series Method (PSM).

Traditional credit scoring methods do not work for these agents as the transaction data is not recorded by a full-service financial institution like a bank. Different data manipulation techniques were explored to present data into features that can be used for scoring. The effects of resulting features were explored using correlation and singular value decomposition, and clustered using - means clustering to assess creditworthiness. After clustering agents into groups, these groups were clustered again to determine low-risk agents, and a formula to determine how much credit can be extended to low-risk agents was devised.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In connection with the RoBUTCHER project – which is a pioneer research effort employing industrial robots for completely automated slaughtering – it was revealed that there are no particular standards regulating directly robotics applied to the agri-food application domain. More specifically, the meat industry and the red meat sector within has only seen hygienic standards regarding machinery, not considering human–robot collaboration or safe autonomous robot operation in the abattoirs. The purpose of this paper is to provide a general overview of the relevant standards (and similar guiding documents) that could be used as pathfinders during the development of inherently safe robotic systems.
