It often happens that these do not offer any possibilities to set the controller parameters, because they are capsulated to outside. The closed-loop systems are then stable, but the systems are often weakly damped and their step responses exhibit overshoot. In the following, a method is described, how such embedded controlled systems can be controlled via a superimposed feedback loop using PID controllers in such a way that the system deviation of the step response is minimized according to the ITAE method. A method from artificial intelligence, hill climbing, is used for this purpose. For the control of such systems, the paper essentially provides PID controller parameters, which are usable for many weakly damped systems. The parameters are verified in a practical application with a speed control of a motor with inertial mass.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129078627","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 ensure resistance to losing their bistability when affixed to bigger structures or clamped, hybrid laminates are used. The laminate’s bistability is triggered by symmetrically embedded bidirectional glass-epoxy layers (BD). The analysis employs an approximate analytical model based on the Rayleigh-Ritz approach. The BD layers have a significant impact on the laminate’s shape at room temperature. The research explores the effect of varying the geometric parameters of the BD layers, specifically their thickness and location from the laminate’s center. In the second part of the study, a new design for a bistable wing is proposed, which combines a flat symmetric platform with a modified hybrid symmetric bistable laminate that acts as a bistable winglet.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"44 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123265406","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}

No other means of transportation would be allowed to operate with a similar rate of safety failure – especially with a known cause. The automobile industry has made strides developing precautions for vehicle operators with tire pressure monitoring systems (TPMSs) and run-flat tires. However, the technology is incomplete. This paper purports to aid the existing tire safety technology by providing additional electro-mechanical options capable of preventing blowout occurrences, reducing rollovers, and minimizing casualties. This proposal incorporates the existing TPMSs and RFTs with overrides, power electronics, tire sensors and voice activation with passive and active schemes based on the tire contact patch.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"616 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131877676","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}

Limiting the residence time to a constant value over long periods can reduce the overall system productivity. The aim of this study was to investigate the performance of a new operational strategy for flat panel photobioreactors when integrated into building façades. This was achieved by examining the impact of variable residence time on biomass production and carbon absorption. The study coupled a detailed chemical kinetics model with Genetic Algorithm in the presence of shading assessment. The chemical model validation showed an average error of 3.8%. Different selection techniques were examined for the employed Genetic Algorithm framework to decrease the computational cost. The feasibility of the optimized photobioreactor was further assessed based on reducing the operational carbon footprint when added to building façades. Results showed that the optimal hourly residence times varied between 0.91 days and 1.97 days with an average value of 1.05 days. This increased the daily biomass generation by 28.8%, from 13.9 g/m2 to 17.9 g/m2. Corresponding CO2 extraction was also increased from 31.4 g/m2 to 34.8 g/m2. On annual basis, integrating the photobioreactors into building façades decreased the operational carbon footprint by 10 kgCO2/m2, 50 kgCO2/m2, and 140 kgCO2/m2 for low-rise, mid-rise, and high-rise buildings, respectively.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128385096","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 increasing complexity, vehicle functions, and operational design pose new challenges for scenario-based testing, as the number of scenarios is enormous. Therefore, an efficient and systematic process is required in the various stages of scenario-based testing. The contribution of this study is to provide sensitivity information of safety related parameters and support logical scenario reduction. This paper presents an approach that supports to optimize the safety-related parameters boundary towards logical scenario reduction. Additionally, sensitivity analysis is applied by computing Variance- Based Sensitivity Analysis (VBSA) indices and prioritize the input parameters. Two datasets are investigated by VBSA based on the input parameters. One dataset is based on the samples from realworld scenarios and other dataset is derived from the samples considering statistic distributions with a specific parameter range. Moreover, the proposed approach is applied to an exemplary use case and the outcomes are demonstrated.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116788974","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}

While the first set is analytically derived by solving the differential equation, the second set is obtained based on a decoupling approach. A finite element code is built to verify the results computed using both sets of equations and excellent agreement is obtained.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125843768","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 narrowing of blood vessels results in symptoms of heart muscle weakness because there is not enough blood to feed. There are three methods of treatment for coronary artery disease including drug therapy, balloon dilation, and stenting (Percutaneous Transluminal Coronary Angioplasty (PTCA), and Coronary Artery Bypass Grafting (CABG) surgery). Several previous research studies found that the stent model created is based on the types of stents used in medicine. The aims of this paper are to conduct a simulation study of the interaction between the stent and the plaque attached to the blood vessels. The 3D model is created by SolidWorks and transferred to Ansys to perform structural analysis, and then the model is transferred to CFX to study the flow over the stent in the blood vessel using the Carreau fluid model. As for structure analysis, it was found that the results achieved using linear simulation and nonlinear simulation were not different. In the stent structure simulation, while the stent expanded over plastic deformation, the maximum stress was on the apex in both the linear and nonlinear studies. Obviously, the nonlinear simulation takes a lot of time to obtain the result when compared to the linear model simulation. The simulation result found that blood flow in the expanded stent is characterized as a loop that necks around struts; this might lead to stent vibration and harm to the blood vessels due to the loop of pressure along the stent length.","PeriodicalId":385901,"journal":{"name":"ICMAME 2023 Conference Proceedings","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123608342","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}
