A Custom Reflectance Goniometer and its Usage in the Development of Gain Reflectors for Electronic-Paper Applications
A modified goniometer has been successfully developed and used to characterize novel electronic-paper (e-paper) devices. A power meter, in conjunction with a DC servo motor, was controlled within a Labview program to automate the collection of data reflected light off of e-paper substrates. Next, …

Study of residual stress in a thin platinum layer by means of nondestructive x-ray diffraction
… The apparatus for the measurements was a Q-goniometer with a Bragg-Brentano focusing beam arrangement and a position sensitive detector. X-ray fluorescence scans were also performed on the sample in order to gain information about its composition. Additionally, a scanning-electron-microscope …

Biomechanical changes to human locomotion due to asymmetric loading of the legs
… to minimize any temporal asymmetry. However, goniometer data demonstrated kinematic changes in response to loading as knee flexion peaked earlier in the gait cycle.

Acute effects of dynamic and static stretch on the peak torque and ROM of the shoulder internal and external rotators.
… and range of motion with a standard universal goniometer was also measured. In sessions two and three, the participant performed either 3x15 repetitions of five dynamic stretches or 3x25 second holds of five static stretches between warm-up and testing. Subjects were randomized as to the order …

Residual stress in Pt coatings under thermal influence
… The apparatus used for the investigation was a Ψ-goniometer with a scintillation detector. The measured data were analysed with "sin²Ψ"-method. The total stress yielded was found to be a superposition of both the thermal and intrinsic stress in the layer. Analytical model, following the method of …

Quantifying ballet technique through turn kinematics for injury assessment
… pirouettes of 1-5 rotations was measured using a goniometer for 12 professional and pre-professional ballet dancers. Plié angle saw no significant difference for different numbers of rotations, but the effect of gender was significant: males pliéd at least 20.3 degrees deeper than females. Average …

Intrinsic factors, performance and dynamic kinematics in optimisation of cycling biomechanics
… Static measures were taken with a standard goniometer (GM), an inclinometer (IM) and dynamic three dimensional motion capture (3DMC) using an eight camera motion capture system. Static and dynamic joint angles were compared over the three trials to assess repeatability of the measurements …

COMPARISON OF EXTERNAL TIBIAL ROTATION IN AFFECTED AND UNAFFECTED KNEES AS MEASURED BY TWO CLINICAL METHODS
… sitting, the goniometric method used a standard goniometer to quantify the angle of the tibial surface relative to the subject’s sagittal plane in degrees of range of motion; whereas the MHT referenced the tibial tubercle relative to the patella, as either producing external rotation (positive …

Cultural Behaviors and Their Influence on the Proximal Femur: Comparisons of Postural Behavior, Occupation, and Subsistence-Settlement Between a Pre-Contact and Historic Sample
… I took various midpoints on the femur and used a goniometer to measure each angle. Activity markers were scored as either present (1) or absent (0). The femoral neck version and neck-shaft angle were statistically significantly higher in Schroeder. Bicondylar angle was within normal range in both …

Comparison of wettability for surface of ocular prosthesis depending on different kind of artificial tear eye drops
… angle was measured by using a contact angle goniometer. The data was analyzed by comparing different materials of ocular prosthesis and artificial tear eye drops. To measure the deposits, we covered a petri dish with 3 ml of artificial tear eye drops and dried for 48 hours at room …

Zein films as substrates for cell attachment
… for cell attachment was measured with a CAM 200 Goniometer. Topographic features were examined by MFP-3D AFM. Results showed that HeLa cells were observed to adhere and grow on zein substrates cast on oxygen treated plasma glass slides. The glutamine effect of zein on HeLa cells was evidenced by …
