Does the Elimination of Thigh Markers Influence the Between-day Variation in Joint Angles?
نویسندگان
چکیده
METHODS Infrared markers (Optotrak® CertusTM, NDI, Waterloo, ON, Canada), were secured to one participant’s pelvis and right thigh, shank and foot. Each segment’s endpoints were located with a digitizing probe and used to define a segment-fixed (local) axis system. Motion trials were collected to compute a “functional” hip joint center (HJC) and “functional” knee joint axis (KJA) [1]. This protocol was repeated 20 times so that 20 unique LSMs could be created. On two separate occasions (reference sessions) the participant performed 3 vertical jumps.

How Does Pricing of Day-ahead Electricity Market Affect Put Option Pricing?
In this paper, impacts of day-ahead market pricing on behavior of producers and consumers in option and day-ahead markets and on option pricing are studied. To this end, two comprehensive equilibrium models for joint put option and day-ahead markets under pay-as-bid and uniform pricing in day-ahead market are presented, respectively. Interaction between put option and day-ahead markets, uncerta...
متن کاملIntersegmental coordination during human locomotion: does planar covariation of elevation angles reflect central constraints?
To study intersegmental coordination in humans performing different locomotor tasks (backward, normal, fast walking, and running), we analyzed the spatiotemporal patterns of both elevation and joint angles bilaterally in the sagittal plane. In particular, we determined the origins of the planar covariation of foot, shank, and thigh elevation angles. This planar constraint is observable in the t...

متن کاملEffect of Tool Shoulder and Pin Cone Angles in Friction Stir Welding using Non-circular Tool Pin
In friction stir welding frictional heat is generated by the rotating tool, sliding over the stationary plate along the weld centre. Tool being the only source of heat producing member, its geometrical design influences the heat generation rate. In this present work, effects of variation in tool shoulder and tool pin taper angles on thermal history during joining are analysed. Tools with triang...
متن کاملDoes Islamic Fasting Affect Gonadotropin around Female Ovulation?
Background The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. MaterialsAndMethods This self-controlled study was performed on 24 adult females. Blood sampling was performed during Ramadan and two months l...
