However, they give rise to harmonic problems during the switching process. It impacts the total system performance.In this paper, Selective Harmonic Elimination SHEPWM was adopted to mitigate these undesirable harmonic distortions. It cancels odd harmonic at optimized switching angles. In this case, it aims to eliminate the first 100 low-order harmonics. The fsolve function was used to calculate the optimized 50 angles for the SHEPWM by solving the non-linear transcendental equations in MATLAB. The resulting SHEPWM is implemented in a low-cost high-performance PIC18F26K22 microcontroller. It controls a pure sine wave single-phase inverter in ISIS space. Finally, an LC low-pass filter is connected at the inverter output to ameliorate its response and obtain a better sinusoidal AC waveform with a lower THD.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"16 1","pages":"127-131"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82459629","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 deal with the stabilization problem, we employ the S-procedure lemma that generates four bilinear matrix inequalities (BMIs). By virtue of the matrix inversion lemma and the Schur complement, these obtained BMIs are therefore transformed into LMIs. The results obtained by the simulation show that the slave mechanical impact oscillator is well controlled and hence track the desired trajectory of the master.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"25 1","pages":"505-512"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90246207","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 our study, we tested the conventional theory (p-q theory) to detect the harmonics present in the electrical system.

These indicators should be chosen according to the company’s objectives, strategies, and key success factors. On the other hand, in a production system, KPIs are not independent and may have inherent interactions with each other. These interactions should be investigated and taken into account in the KPI selection process. The goal of this research is to present a decision support framework based on a Fuzzy Cognitive Map (FCM) for guiding decision-makers in the selection of KPI. The model is based on the idea that KPI may be assessed and chosen based on their impacts on the company’s strategic objectives. In addition, the model allows for the consideration of different causal interdependence between the KPI.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"24 1","pages":"97-102"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87205315","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}

This approach is essentially performed by applying a multi-criteria analysis based on a comparison study including four criteria.

Information about vulnerabilities is also available on the open web in an unstructured format that developers can take advantage of to fix vulnerabilities in their IT applications. SQL injection (SQLi) attacks are frequently launched with the objective of exfiltration of data typically through targeting the back-end server organisations to compromise their customer databases. There have been a number of high profile attacks against large enterprises in recent years. With the ever-increasing growth of online trading, it is possible to see how SQLi attacks can continue to be one of the leading routes for cyber-attacks in the future, as indicated by findings reported in OWASP. Various machine learning and deep learning algorithms have been applied to detect and prevent these attacks. However, such preventive attempts have not limited the incidence of cyber-attacks and the resulting compromised database as reported by (CVE) repository. In this paper, the potential of using data mining approaches is pursued in order to enhance the efficacy of SQL injection safeguarding measures by reducing the false-positive rates in SQLi detection. The proposed approach uses CountVectorizer to extract features and then apply various supervised machine-learning models to automate the classification of SQLi. The model that returns the highest accuracy has been chosen among available models. Also a new model has been created PALOSDM (Performance analysis and Iterative optimisation of the SQLI Detection Model) for reducing false-positive rate and false-negative rate. The detection rate accuracy has also been improved significantly from a baseline of 94% up to 99%.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"32 1","pages":"513-517"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82609291","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}

It is applied in several fields where quantitative measurements are made. In fact, in any industrial activity (food processing, electrical energy, chemistry, mechanics, aeronautics, space, defense, agriculture, electronics) various measuring instruments are used. After a certain period of operation, their indications will be erroneous, which leads to major risks for the safety of people and industrial installations. Thus all equipment drifts over time, it is a well known phenomenon. A measuring instrument that is \"accurate\" today will not be so tomorrow because it will have drifted! The causes of drift are multiple and varied (mechanical origin: shocks and vibrations, oxidation, wear, conditions of use, aging...). This calibration interval or drift is determined either by the manufacturer or by the needs of the company or the laboratory. Historically, the periodicity is 12 months in metrology for all the instruments, this drift allows to have a management of periodicity of the equipments but sometimes the calibration will be with a high cost. Therefore, to avoid costly periodic calibrations, methods have been created to adjust and optimize calibration costs according to the criticality and use of the measuring instrument. The optimization and justification of periodicity are increasingly crucial problems over time, they are now the subject of strict guides defining the methods of calculating periodicity such as the method of max drift, the method of weight and the method OPPERET. In this paper, we will demonstrate the adequate method for a special laboratory that has a limited number of equipments according to the ISO/CEI 17025 version 2017.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"10 1","pages":"336-339"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79074108","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}
