PURPOSE The objective of this study was to describe spatial and temporal parameters during gait in pregnant women, and to compare it with women in post-partum and with a control group. METHODS To investigate alteration in natural locomotion, we used an electronic walkway (GAITRite system). Fifty-eight pregnant women (four last months of pregnancy), nine post-partum women and twenty-three heal...

PURPOSE This study introduces a reading chart application for the iPad tablet in the Korean language and investigates the reading speed in a normal-sighted population according to age group. METHODS Sixty-three Korean sentences were selected from textbooks for second grade elementary school students. A commonly used typeface in everyday printed material, "BatangChe," was used. Letter size was...

This paper presents a new variable step-size normalized subband adaptive filter (VSS-NSAF) algorithm. The proposed algorithm uses the prior knowledge of the system impulse response statistics and the optimal step-size vector is obtained by minimizing the mean-square deviation(MSD). In comparison with NSAF, the VSS-NSAF algorithm has faster convergence speed and lower MSD. To reduce the computa...

This study investigates the relation between walking speed and the distribution of peak plantar pressure and compares a traditional ten-region subsampling (10RS) technique with a new technique: pedobarographic statistical parametric mapping (pSPM). Adapted from cerebral fMRI methodology, pSPM is a digital image processing technique that registers foot pressure images such that homologous struct...

In this research, dynamic analysis of the rotational slender axially moving string is investigated. String assumed as Euler Bernoulli beam. The axial motion of the string, gyroscopic force and mass eccentricity were considered in the study. Equations of motion are derived using Hamilton’s principle, resulting in two partial differential equations for the transverse motions. The equations are ch...

ABSTRACT- Noise is considered as one of the most debilitating conditions in farming operations. In this study, a number of factors affecting the noise generated by Sampo 3065 combine harvesters were evaluated. Factors were engine speed and gear ratio for combines with and without original cabins. A factorial experiment arranged as a completely randomized design with four replicates was used. Re...

The objective of this study was to assess the accuracy of using speed and grade data obtained from a low-cost global positioning system (GPS) receiver to estimate metabolic rate (MR) during level and uphill outdoor walking. Thirty young, healthy adults performed randomized outdoor walking for 6-min periods at 2.0, 3.5, and 5.0 km/h and on three different grades: 1) level walking, 2) uphill walk...

1 2 One of the main challenges in conducting detailed analysis of cyclist behavior is the lack of reliable 3 data. Collecting data through manual methods is a labour-intensive and time consuming process. 4 Two of the important areas of cyclist data collection are volume counts and average speed 5 measurement. A volume count is important as it provides the basis for necessary exposure measures 6...
