Vibration Based Diagnosis for Planetary Gearboxes Using an Analytical Model by Liu Hong, Yongzhi Qu, Yuegang Tan, Mingyao Liu, Zude Zhou

“…The application of conventional vibration based diagnostic techniques to planetary gearboxes is a challenge because of the complexity of frequency components in the measured spectrum, which is the result of relative motions between the rotary planets and the fixed accelerometer. In practice, since the fault signatures are usually contaminated by noises and vibrations from other mechanical components of gearboxes, the diagnostic efficacy may further deteriorate. …”

Differences in Physical Activity between Patients with Peripheral Artery Disease and Healthy Subjects by Sumiko Shiba, Akiko Shiba, Atsutoshi Hatada

“…We measured the time spent at light, moderate, or vigorous physical activity using triaxial accelerometer and calculated PAL. Intermittent claudication onset distance and maximum walking distance were defined as the distance walked at which the subject first reported leg pain and the distance at which the subject was unable to continue walking because of leg pain, respectively. …”

Comparative responses to a physical activity program in older adults by Carlos X. Torres-Ramos, Rachel E. Salyer, Isaura M. Castillo-Hernández, Ellen M. Evans

“…Physically inactive OAs (71.3 ± 4.3 years old; n = 28, 64% female) completed a PA program that included: a twice-weekly supervised exercise class, Facebook engagement, and an unsupervised walking prescription. PA (accelerometer, questionnaires, and logs), muscle capacity (leg strength and power), LEPF [6-minute walk (6 MW), 8-foot up and go (UPGO), chair stands (CHAIR), transfer task (TRANSFER)], program engagement, and Facebook participation (attendance logs) were assessed. …”

Passive Monitoring of Parkinson Tremor in Daily Life: A Prototypical Network Approach by Luc J. W. Evers, Yordan P. Raykov, Tom M. Heskes, Jesse H. Krijthe, Bastiaan R. Bloem, Max A. Little

“…We evaluated our approach using data from the Parkinson@Home Validation study, including 8 PD patients with tremor, 16 PD patients without tremor, and 24 age-matched controls. We used wrist accelerometer data and synchronous expert video annotations for the presence of tremor, captured during unscripted daily life activities in and around the participants’ own homes. …”

Identification of Pyrotechnic Shock Sources for Shear Type Explosive Bolt by Yanhua Li, Shihui Xiong, Yuan Li, Xiaogang Li, Yuquan Wen, Huina Mu, Zhiliang Li

“…Their acceleration responses at 15 cm from the shock source center on 60 cm × 60 cm × 1 cm equivalent aluminum plate were measured by using the piezoresistive accelerometer. On this account, the relative contribution values along with frequency and the mean relative values without regard to frequency of various sources were calculated in high and low preload. …”
