In manufacturing, the optimum ESR range is characterized by the load transient tests for a range of load current and ESR values. Currently, the stability condition is determined by observing the output voltage oscillation counts. However, this process is less accurate and time-consuming. A more precise stability condition can be obtained by measuring the phase margin based on the frequency response. Yet, it needs to be conducted in an openloop condition, which is difficult for the LVR integrated circuit. Therefore, an approach is developed to noninvasively measure the phase margin in closed-loop conditions based on the LVR frequency response. Furthermore, five machine learning (ML) methods were proposed to solve the regression problem to estimate the phase margin for any operating points. Those ML methods are support vector machine, decision-tree, ensemble method, neural network, and Gaussian process regression. The inputs are load current and ESR, while the phase margin acts as the targets in the ML training. In addition, hyperparameters in each ML method are also optimized. Results showed that Gaussian process regression produces validation RMSE, MSE, MAE, and R2 of 0.1736, 0.0301, 0.0612, and 1.0000, respectively. The trained ML methods were then used to estimate the phase margin. To conclude, the phase margin in the LVR circuit can be effectively estimated without breaking the internal control loop.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275594","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 robotics industry is one of the fields that can potentially benefit from implementing 3D printing technologies. The combination of industrial robots and additive manufacturing technologies provides manufacturers with the ability to fabricate large and heavy products with high dimensional accuracy and automate this manufacturing process. The robotics industry lacks its own manufacturing facilities and has to outsource special orders to manufacturing companies. Outsourcing, however, implies additional expenses and time delays. Therefore, the relevance of integrating additive manufacturing into the robotics industry is the objective of research since it can considerably favor the development of this industry. The primary aim of this work is to develop and design 5 DOF 3D printed robotic manipulators. The developed model of the manipulator was tested via numerical simulations. The results clearly demonstrated the areas of stress concentration and the areas of the prototype that are subjected to the least stress. This set of results helped to perform topological optimization and improve the design and performance of the robotic manipulator. The optimized model was manufactured using the method of fused deposition modelling. The manipulator was assembled and actuated by six servo motors. The current progress of the research will be followed by the development of the control algorithm and performance evaluation to estimate the functionality of the manipulator. Distribution of the infill density throughout the assembly to reduce the material without losing the strength of the assembly is another important object of concern.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127278418","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}

For SPR biosensor development, efficient immobilization of biorecognition molecules onto the sensor surface is always essential. In SPR biosensor, gold (Au) is usually preferred to be used than silver (Ag) or other metals because it has good resistance to oxidation and corrosion in different environments. However, biomolecules adsorb poorly on gold which might limits the sensitivity of a conventional SPR biosensor. Therefore, an adhesive linker layer such as self-assembled monolayer (SAM), between the metal and ligands is required to functionalize the metal film and enhance the sensitivity of the SPR based sensor. The criteria that were taken into consideration for the formation of SAM layer was discussed and, the binding of a 11-MUA thiols onto an Au/BK7 prism will be experimentally demonstrate. The sample of 11-MUA/Au/BK7 sample was subjected to Raman spectroscopy for surface characterization. The present study confirms the binding of thiols SAM into gold surfaces which is important for the development of a highly performing biosensor.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130578949","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}

Specifically, performing the mapping and localization task in such an environment is non-trivial. Few factors need to be considered including the dynamic of the hovercraft and the severity of the surrounding environment. In this study, an investigation was carried out to evaluate the performance of a visual simultaneous localization and mapping (SLAM) technique in generating the environment model of a simulated river. The main objective of this study is to build a SLAM system of a hovercraft such that the robot can traverse the river surface autonomously. A depth camera was used as the visual sensor, and acts as the main odometry in the process of mapping and localization of the hovercraft. Data from the visual sensor was tuned and optimized to adapt to the river surface environment. The performance of the tuned SLAM was measured by comparing several configuration settings to get the best output. The result of this study shows that with proper tuning and optimization, a SLAM technique can be used to generate an accurate river surface map and monitor the hovercraft trajectories.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115940569","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}
