abstract

objectives: the purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. methods & materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. a four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. kinematic data collected using four high speed video based cameras at a sampling frequency of 90 hz.the t-testfor independent samples (α≤0.05) applied for statistical analysis. results: significant differences showed longer stance phase (2%), longer push-of time (4%), slower cadence (13%), slower speed (28%) and shorter step length (15%) for elderly in comparison with young subjects, though no significant differences were seen in double supporttime between two groups. conclusion: due to results, spatio-temporal changes are mainly attributed to the age-related decreases in muscular flexibility, joints>ranges of motion and neuromuscular control in elderly people.

Spatio-temporal 3D Gait Recognition

In the current security climate, the need to identify unknown subjects quickly and efficiently has never been greater. In a real-world open-space scenario, it is often difficult to ensure the compliance of an unknown subject and the use of invasive contact biometrics such as fingerprint, iris or DNA would prove to be difficult and would cause congestion problems. For such a scenario, biometrics...

Investigation of Long Term Trend of Spatio-Temporal changes of Sea Surface Temperature in Oman Sea

Considering the vast application of sea surface temperature in climatic and oceanic investigations, this parameter was studied in Oman Sea from 1986 to 2015. The SST was surveyed using trend analysis and Global and local Moran’s I spatial autocorrelation. In trend analysis, the Mann-Kendall test was used to determine the trend of SST changes and the Sen's Estimator method was used to examine th...

Gait Volume : Spatio-Temporal Analysis of Walking

This paper describes a new approach for identifying a person from a spatio-temporal volume that consists of sequential images of a person walking in an arbitrary direction. The proposed approach employs an omnidirectional image sensor and analyzes the three dimensional frequency properties of spatiotemporal volume, because the sensor can capture a long image sequence of a person’s movements in ...

Spatio-Temporal Changes of Natural Vegetation Disturbance in the Ahle Iman Watershed, Ardabil Province

The present study aimed to assess the spatio-temporal changes in the natural vegetation cover of Ahl Iman watershed, Ardabil province. For this purpose, land use maps of the three years (2000, 2010, and 2020) were extracted from Landsat satellite images. Then, seven landscape metrics (patch density, edge density, patch richness, splitting index, contagion index, Euclidean nearest neighbor dista...

Spatio-temporal changes of water quality variables in a highly disturbed river

Quality of river varies widely depending on the land use in the catchment and environmental factors. Many rivers in developing countries are unhealthy because they contain harmful physical, chemical and biological agents. Zanjanrud River, located in Zanjan Province, Iran, where recently faced human intervention needs a regular monitoring from upstream to downstream for sustainable management. H...
