This study aims at assessing the kinematic characteristics of the sit-to-stand transition from a quantitative perspective, using a wireless IMU sensor, and describes a set of parameters suitable for evaluating the movement performance in everyday practice. Methods: An acquisition campaign was designed and carried out on 20 healthy subjects and 13 patients to evaluate acceleration and angular velocity generated during a sit-to-stand task. For each subject, at least four acquisitions were performed, to create a final dataset of 173 acquisitions. The values of the proposed parameters were computed, and results were analyzed with descriptive statistics. Results: According to the proposed parameters definitions and the analyzed dataset, acceleration-and angular velocity-related parameters present statistically significant differences between healthy and pathological data samples, unlike total time TT.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129006288","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 work, a 1D mathematical model is reported and solved using the control volume method to investigate the distribution of seven temperatures in the triple pass flat plate solar air heater (SAH). A compact solver for predicting local temperatures of a multiple-pass SAH has been rarely found in the open literature. The collector parameters are fixed while the mass velocity of the air is varied from 0.0121 to 0.07246 kg/m2-s. The results of temperature distribution analysis show that the absorber plate temperature reaches a maximum in the center of the plate which is different from that of a double pass solar air collector. When the air flow rate is large, the upper glass is no longer able to transfer heat to the air, so the efficiency of the triple pass collector decreases. It is concluded the pertinent air flow rate of 0.04 kg/m2-s to obtain the highest effective efficiency of 64%. The present study is expected to develop multi-parametric study and apply finned, baffled or ribbed air channels.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115087501","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 detail, on the basic of the linear matrix inequality (LMI) approach, a nonlinear unknown input observer (NUIO) is designed to simultaneously estimate the sensor fault and output of position that is not impacted by the external disturbance. Next, a fault detection module is constructed to detect sensor fault and feedback the estimated position to the controller when the fault occurs. For the purpose of approximating and reducing the influence of the mismatched disturbance, a radial basis function neural network (RBFNN) is deployed. The combination of NUIO, RBFNN in a dynamic surface control (DSC) approach is introduced to not only achieve precision tracking control but also guarantee a stable system in the event of sensor fault. Furthermore, the Lyapunov function method is utilized to analyze the stability of the resulting closed-loop system. Finally, simulation results and comparison studies are presented to verify the effectiveness and feasibility of the theoretical claims.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121073251","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}

Considering the anisotropic properties through the magnetic fields have a significant impact on the surface polarization of the material, it is critical to examine the role of the magnetorheological compound as a triboelectric layer in triboelectric nanogenerator (TENG) output performance. Here, polyvinylidene fluoride (PVDF) and ferromagnetic cobalt ferrite $(mathbf{CoFe_{2}O_{4}})$ nanoparticles were used to fabricate a magnetic polymeric composite (MPC) film as a triboelectric layer to enhance the output performance of TENG. The polar crystalline phase content of PVDF was considerably enhanced with the addition of $mathbf{CoFe_{2}O_{4}}$ nanoparticles, going from 51.2 % with pristine PVDF to 77.7% with 5 wt. % $(mathbf{CoFe_{2}O_{4}})$ in MPC, demonstrating a rise in negative charge and dielectric constant of the MPC film. Therefore, the output performance of the MPC5-TENG was shown a significant increase with a peak current of $2.27mumathbf{A}$” a peak voltage of 17.2 V, and power density up to 90 mW/m2, giving 2.4 times higher than pristine PVDF - TENG. Finally, with exceptional stability and durability, we anticipate that this MPC- TEN G will bring additional views on hydrokinetic energy harvesting in the future","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124017720","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}

However, these batteries suffer capacity loss due to different ageing mechanisms in various applications. Despite several existing models, lack of accurate predictability of capacity degradation limits the advancement of Li-ion batteries. The present work focuses on prediction of battery useful capacity degradation using long-short term memory (LSTM) transfer learning neural network model. At first, a base model was developed and trained using all the (100%) degradation data available at 0°C and 10°C environmental temperatures. Thereafter, the training of the base model was fixed, and additional hidden layers were added on top of the base model to further fine tune it with only the initial 30% degradation data available at 25°C environmental temperature. The remaining (70%) data of the 25°C case was tested for model prediction. To decide the number of fixed hidden layers to be transferred from base model to transfer model and the number of additional hidden layers on top, an optimization for minimum cross validation error was performed. It was found that the resulting model was able to forecast the remaining battery degradation with 96% accuracy. The model prediction was also compared with LSTM deep learning architecture without using transfer learning. The LSTM with transfer learning model was found to be 17% higher in prediction accuracy than that without utilizing transfer learning.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115962279","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}
