Epilepsy is a disease that tends to occur repeatedly and cannot be cured. However, the occurrence of epileptic seizures can be controlled through medication. This study tried to detect epilepsy features via electroencephalogram (EEG) data analysis. The EEG data is divided into several windows using segmentation or decomposition. EEG Data will be extracted from each window using a modified Weighted Permutation Entropy (WPE) to produce one feature per window where the number of features of each EEG data will equal the number of windows obtained in the EEG data recording process. This research used k-fold cross-validation by dividing the data into training and testing data, classified using a Support Vector Machine. The EEG database used in this study came from Temple University Hospital EEG (TUH EEG), obtained online with as much as 1500 data. This EEG database consists of epileptic seizures (set 1) and non-epileptic seizures (sets 2, 3, 4, 5), each with 300 data. Based on testing, using this method produces an average accuracy of 81.29%.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125108388","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 fixed-focus lens with moving displacements produces multiple images with varying depths of focal field. 3D image characteristics of hex nuts are extracted as center coordinates, sizes, and tilt angles. Multiple nut images are convolved using a band-pass filter to evaluate the highest score from different displacements, and the three-dimensional height can be obtained by the depth gray-scale images. The individual nut regions can be discriminated by gray difference values, meaning less values classified as the same region. To improve the characteristic qualities, the region growing algorithm is used to segment the nuts and remove noise according to set area size groups. Comparing pixel coordinate and real-world coordinate leads to the tolerance of center coordinates, sizes and tilt angles for the precision analysis.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133637123","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}

Since the number of degrees of freedom of an ATMD is larger than the number of its actuators, it is an underactuated system. It is also proved in this paper that the controllability matrix of the simplest ATMD system is ill-conditioned. An intuitive controller is suggested to stabilize the primal system by using the feedback linearization design, but it will result in unbounded auxiliary dynamics. A strategy to preserve passivity in the auxiliary system is proposed to modify the feedback linearization controller. The design problem can then be regarded as the solution of the Lyapunov equation, and may be solved numerically.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131264331","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}

These diseases have a significant impact on patients and healthcare systems. Innovative technologies like chatbots, which promise to improve the management of chronic diseases, have emerged as potential solutions to these difficulties. Chatbots are man-made brainpower (artificial intelligence) programs that can recreate discussions with people and give customized and practical consideration. The primary purposes of this study are to investigate the most important applications of chatbots in the management of chronic diseases, including personalized education, symptom monitoring, medication management, and lifestyle coaching. In addition, it discusses the potential advantages and disadvantages of chatbots in the management of chronic diseases, including the need for human oversight, data privacy, and patient engagement. The paper concludes that, although chatbots have the potential to transform the management of chronic diseases by providing personalized and cost-effective care, careful consideration of ethical, legal, and regulatory frameworks is required for their integration into healthcare systems.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122859855","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}

We conducted computational training and testing experiments of the ESN-based nonlinear MPC (NMPC) for testing the tracking task of the discrete-time nonlinear plant.

Fewer studies are used for system dynamics modeling, simulation, and identification. To simulate the transient response of a dynamical system, most of the studies applied recurrent neural network (RNN), which uses feedback connections to consider the influence of past state when computing current state. However, it still needs a much larger structure relative to the order of the system dynamics for neural network to have a good fitting performance. To reduce the model complexity and increase the accuracy, this paper presents a data-driven based modeling for a motor-driven propeller system by applying the neural ordinary differential equation (i.e., neural ODE). It is worthy to note that the neural ODE builds a continuous-time model for system identification, which can reduce large amount of memory demands to store the past states generated by the RNN. By comparing with the exact physical model, the discrete-time RNN, and the nonlinear autoregressive with exogenous (NARX) model, numerical simulations show that the proposed neural ODE model gives the best fitting results in the presence of measurement noise.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121538795","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 used in many applications, such as speech recognition, speaker diarization, and speech synthesis. However, because manual segmentation can be laborious and time-consuming, forced alignment algorithms are used to automate the process by aligning the speech audio to its corresponding text transcription at the phoneme or word level. To overcome this problem, one of the solutions is a forced alignment tool called Montreal Force Aligner. This tool has two requirements: a language acoustic model and a corresponding language dictionary. The challenges are determining a suitable recipe for training the model and achieving a good alignment with minimum error. In this study, training and evaluation are conducted for the Indonesian language using the Montreal Forced Aligner. A conversational corpus from a range of five to 30 speakers with various duration between one hour and two hours is used as an input to train the acoustic model. Then, the model is employed to align the conversational Indonesian corpus using the ASR-INDOCSC test set. Our findings include a recommendation training strategy for developing an Indonesian language acoustic model using the Montreal Forced Aligner tool, which measures the number of speakers and hours required.","PeriodicalId":142483,"journal":{"name":"2023 Sixth International Symposium on Computer, Consumer and Control (IS3C)","volume":"46 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123410011","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}
