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 evolution of wireless industry and mobile users requirements enhance the exploration of new spectral access strategies. Even though, millimeter waves offer promising bandwidth, it suffer from limited range due to high path loss. Therefore, new generations of cellular networks are interested in Sub-6GHz spectrum that has adequate propagation properties and has many bands released for unlicensed access. However, these frequencies are used by the majority of commercial wireless technologies such as WIFI, Bluetooth and 3G/4G cellular networks. Their spectral coexistence with new wireless services over unlicensed bands requires mutual interference control based on controlling the power levels of co-located operators. To address this issue, we present a coexistence solution based on power control enabling maximum cell transmission capacity. We formulate the interaction between two co-located operators as a competitive game. Each operator-user pair tries to maximize its sum transmission capacity over the target channels under maximum power constraint. We develop the analytical expressions of the optimal power allocation vectors, then we keep the base stations playing the game iterations until the convergence to a Nash equilibrium. We provide simulation results proving the performance of the proposed model.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"73 1","pages":"178-182"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77399461","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}

A considerable number of employees are faced with anxious thoughts because of the workplace isolation. This was proved by a pilot study done among 102 employees in Sri Lanka.

One of the most difficult problems in elastic optical transport networks is the Routing and Spectrum Assignment (RSA). The goal of this study is to create and develop effective algorithm for internet traffic routing in SDM-based Elastic Optical Networks (EONs).
