These policies are transposed and expressed in the legislation of each Member State which establishes national objectives and specific intervention measures for the national context. In this work, incentive policies are compared according to the actual state of achievement of defined targets. Following the definition of the criteria for the classification of incentives, the SCORE investment calculator is presented. This online tool compares the economic convenience of different incentive policies and it represents a useful operational tool for the beneficiaries of the investment, but also to verify the effectiveness of the incentive policies themselves and, if necessary, redefine them.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121272584","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}

To fit multiple biological data with SIR type equations requires fitting coefficients of these equations by an initial guess and applying optimization methods. These coefficients are also extremely initial value-dependent. In the vast publication of these types, we hardly see, among simple to highly complicated SIR type methods, that these methods presented more than a maximum of two biological data sets. We propose a novel method that integrates an analytical solution of the infectious population using Weibull distribution function into any SIR type models. The Weibull-SIRD method has easily fitted 4 set of COVID-19 biological data simultaneously. It is demonstrated that the Weibull-SIRD method predictions for susceptible, infected, recovered, and deceased populations from COVID-19 in Kuwait and UAE are superior compared with SIRD original ODE model. The proposed method here opens doors for new deeper studying of biological dynamic systems with realistic biological data trends than providing some complicated, cumbersome mathematical methods with little insight into biological data's real physics.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116479094","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}

Methods: Three observers detected 25 cephalometric points on 60 random cone-beam volume tomograms three times. The points were assigned to three groups: 1. paired points of maxillae, 2. paired points of the mandible, 3. unpaired midpoints. The standard deviation of each landmark was calculated and the intra- and inter-examiner reliability was assessed with intraclass correlation coefficient (ICC) and analysis of variance (ANOVA). Three regression planes were created from the points of each group and the most reliable regression plane was determined based on the mean distance of the remaining landmarks from the planes. In the most accurate group we analyzed which combination of three points provide a reliable facial symmetry plane and which points can substitute each other. Results: The ICCs were high≥0.90, the SDs were lower than 2.00 mm except for Arcus Zygomaticus, bilateral Apertura Pyriformis (y, z), Foramen mentale left (x, z) and Crista Galli. The mean distance and SD of the measured points from the regression plane constructed of the unpaired midpoints was the lowest as compared to the plane of mandibular and maxillary points. In this group the following combinations framed the most accurate midsagittal planes: N-S-B, N-S-D, G-S-B and G-S-D. Conclusions: Thanks to the suitable landmarks, a reliable midsagittal plane can be created with this method, even if some landmarks are injured.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133011357","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}

Sedaghat, Seyed Amir Abbas Oloomi, Mahdi Ashtian Malayer, N. Rezaei, A. Mosavi","doi":"10.1109/CANDO-EPE51100.2020.9337799","DOIUrl":"https://doi.org/10.1109/CANDO-EPE51100.2020.9337799","url":null,"abstract":"On 30 July 2020, a total number of 301,530 diagnosed COVID-19 cases were reported in Iran, with 261,200 recovered and 16,569 dead. The COVID-19 pandemic started with 2 patients in Qom city in Iran on 20 February 2020. Accurate prediction of the end of the COVID-19 pandemic and the total number of populations affected is challenging. In this study, several widely used models, including Richards, Gompertz, Logistic, Ratkowsky, and SIRD models, are used to project dynamics of the COVID-19 pandemic in the future of Iran by fitting the present and the past clinical data. Iran is the only country facing a second wave of COVID-19 infections, which makes its data difficult to analyze. The present study's main contribution is to forecast the near-future of COVID-19 trends to allow non-pharmacological interventions (NPI) by public health authorities and/or government policymakers. We have divided the COVID-19 pandemic in Iran into two waves, Wave I, from February 20, 2020 to May 4, 2020, and Wave II from May 5, 2020, to the present. Two statistical methods, i.e., Pearson correlation coefficient (R) and the coefficient of determination (R2), are used to assess the accuracy of studied models. Results for Wave I Logistic, Ratkowsky, and SIRD models have correctly fitted COVID-19 data in Iran. SIRD model has fitted the first peak of infection very closely on April 6, 2020, with 34,447 cases (The actual peak day was April 7, 2020, with 30,387 active infected patients) with the re-production number R0=3.95. Results of Wave II indicate that the SIRD model has precisely fitted with the second peak of infection, which was on June 20, 2020, with 19,088 active infected cases compared with the actual peak day on June 21,2020, with 17,644 cases. In Wave II, the re-production number R0=1.45 is reduced, indicating a lower transmission rate. We aimed to provide even a rough project future trends of COVID-19 in Iran for NPI decisions. Between 180,000 to 250,000 infected cases and a death toll of between 6,000 to 65,000 cases are expected in Wave II of COVID-19 in Iran. There is currently no analytical method to project more waves of COVID-19 beyond Wave II.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114917341","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 this paper an optimized TSF is presented to enhance the torque profile of SRM over an extended speed range while maintaining an acceptable value of the average output torque. A secondary objective is to minimize the RMS phase current also included in the optimization problem. The control variables are the switch-on angle and the overlap angle. An improved version of the ant colony optimization (ACO) based procedure is employed in this work. Additionally, a highly trusted SRM model is built using finite element method (FEM), this model is then adopted by the optimizer to accurately select the optimal values of the control variables. Simulation is carried out on 4 kW, 1500 rpm, four-phase 8/6 SRM.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129483516","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 first outlet is the Mochovce nuclear power plant and the second on the outlet line of the Vojany thermal power plant. The height is mainly focused on reducing oscillations in short circuits.

It is assumed that S-FOC should have better performance over DTC-SVM due to it's voltage decoupling scheme.
