Step Counts Using a Tri-axial Accelerometer during Activity
Physical activity has been associated with health improvements in a number of populations. Step counting is one of the most commonly used measures of physical activity [1]. Due to their small size and light weight, the use of wearable sensors for step counts has been investigated in many studies [2, 3] as they are suitable for home deployment. One of the main issues with step counts as a physic...
متن کاملPosture and Activity Detection Using a Tri-axial Accelerometer
Quantifying activity levels among healthy older adults and patients can provide objective information on sedentary behavior and physical function [1]. In order to accurately quantify activity in the free-living environment, a robust method for classifying posture and activity needs to be established. Therefore, the purpose of this study was to validate the identification of static postures and ...
متن کاملNon-Parametric Bayesian Human Motion Recognition Using a Single MEMS Tri-Axial Accelerometer
In this paper, we propose a non-parametric clustering method to recognize the number of human motions using features which are obtained from a single microelectromechanical system (MEMS) accelerometer. Since the number of human motions under consideration is not known a priori and because of the unsupervised nature of the proposed technique, there is no need to collect training data for the hum...
متن کاملEvaluation of a threshold-based tri-axial accelerometer fall detection algorithm.
Using simulated falls performed under supervised conditions and activities of daily living (ADL) performed by elderly subjects, the ability to discriminate between falls and ADL was investigated using tri-axial accelerometer sensors, mounted on the trunk and thigh. Data analysis was performed using MATLAB to determine the peak accelerations recorded during eight different types of falls. These ...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
