Since the reshuffling of any data value does not change the probability distribution, the sense of correlation or covariance in the data is lost, especially when dealing with self-affine time series. An alternative approach is to use poly-scale analysis. This paper describes two poly-scale algorithms: the length fractal dimension and variance fractal dimension and evaluates their accuracy and precision. First, we generate white Gaussian noise and fractal Brownian motion using the concepts of fractional Brownian motion and the discrete Fourier transform. Next, we evaluate the performance of these measures. Since many processes are nonstationary, we also present a stationarity-frame detection technique based on the One-Way ANOVA and Bartlett tests. Our results show that these poly-scale techniques can always be used as reliable tools for different purposes in self-affine data analysis. sure that the generator transient does not affect our data. Next, we investigate two methods to synthesize two classes of fractional noise with known fractal properties. We further describe two statistical tests, the One-Way ANOVA and Bartlett tests, to determine the appropriate stationarity frame of the synthesized time series.

Nataraj","doi":"10.11159/icbes22.132","DOIUrl":"https://doi.org/10.11159/icbes22.132","url":null,"abstract":"- Each year in the United States, over 2,000,000 individuals suffer from neuromuscular disorders that severely impair movement abilities. Physical therapy is the predominant option for rehabilitating motor function for these patients; however, traditional therapies often focus on physical training without greater cognitive engagement or leveraging of motor learning principles. As such, computerized interfaces for rehabilitation, such as virtual reality and robotics, are more promising given their natural approaches to motivate and provide enhanced feedback about performance while re-training motor skills. Our laboratory has prototyped an upper-extremity brace device integrated with a virtual reality environment for isometric training of improved muscle-level control of the upper-body for persons with motor disability. This research platform includes a position-adjustable restrictive upper-extremity brace instrumented with sensors for skin-surface electromyography (EMG, measure muscle activity) to control virtual avatars and vibration motors for haptic guidance cues during training. The core objective of this research is to adapt the current brace design to better include instrumentation elements (EMG sensors, vibration motors) onboard the brace towards an embodiment of this device that is self-contained and with greater commercial potential. Specifically, this project will focus on building the next version of this brace system that allows for custom-placement of affordable (not high-end research-grade) commercial EMG (Myoware) sensors at locations personally fitted to each participant. The Myoware sensors will be embedded onto the current upper-body restrictive brace through modular attachments based on designs developed in SolidWorks as presented in this paper. The SolidWorks design utilizes sliding mechanisms, screws, springs, and clamps to make the modular attachment more user-friendly and position adaptable in three dimensions. Embedding Myoware sensors onto the brace design replaces the need to tape research-grade (Delsys) sensors onto each participant to ensure flush and consistent contact with each participant arm for robust EMG measurements and reliable transfer of haptic feedback. Overall, these improved design implementations will result in a version of this device that is more affordable, easier to use, more customizable to each user, and facilitates greater portability. The potential customers and stakeholders would include not only patients, but also clinical support staff and telehealth companies. This versatile, advanced system for computerized rehabilitation will be valuable to any communities of neuromuscular disorders affecting upper-body function that benefit from motor rehabilitation.","PeriodicalId":294100,"journal":{"name":"World Congress on Electrical Engineering and Computer Systems and Science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121700864","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 complex visual task entailed a set of twelve words that could be grouped based into 1, 2, or 3 categories or sets, e.g., the words bed, pillow, headboard, etc. can be grouped into a single set that is bedroom.

The purpose of this study is to combine interaction design concepts to suggest improvements to supermarkets and create a better user experience. Firstly, the theory of supermarkets, the current situation of hypermarkets, interaction design, and persona is summarized through literature research. Then an observational survey was conducted on the user characteristics and behaviors of supermarkets, etc., and a 5-point Likert scale was used to analyze the user experience satisfaction at each behavioral stage. Based on the observation results, a middle-aged female teacher was set as a persona, and the user experience analysis was conducted for each of the three cases through the six elements of interaction design to find out the inconvenience and problems of the users in the food section of the supermarket. In the conclusion section, a proposal is made based on the results of the analysis through the six elements of interaction design. In future research, the interaction design study will include the analysis of relevant aspects of the self-checkout system.

Herein, we are introducing an alternative hybrid approach, which features: measures of the subject’s hearing acuity. All three features operate in tandem in order to provide a maximally efficient solution for AEP artifacts, by reducing the in a cohort of healthy subjects (n=10) and patients with epilepsy (n=10) under four conditions (i.e., resting EEG with and without acoustic mask and sham TMS-EEG with and without acoustic mask at various stimulus intensity levels).

Finite element models can be used to study these properties to a certain extent. Unfortunately, such models are computationally very expensive.

In this work, we use Krylov-subspace based model order reduction to reduce a simplified, linearized finite element model of an electrode-neuron interface. This facilitates the coupling to the Hodgkin-Huxley model at system level and reduces the computational time considerably.

Tracking each vehicle’s ECU status such as motor speed, fuel consumption, and engine temperature, while logging and analyzing the data could help in monitoring and ultimately predicting vehicle failures before they happen. Building upon the CAN bus architecture, this paper presents a systematic approach that employs the J1939 protocol, to form a high layer protocol to log and parse data from the bus using the industry-standard Media Descriptor File (MDF) file format and utilizing an Internet of Things (IoT) device in addition to cloud computing.
