A case study visualisation approach to examining the coordination and variability of multiple interacting segments is presented using a whole-body gymnastic skill as the task example. One elite male gymnast performed 10 trials of 10 longswings whilst three-dimensional locations of joint centres were tracked using a motion analysis system. Segment angles were used to define coupling between the arms and trunk, trunk and thighs and thighs and shanks. Rectified continuous relative phase profiles for each interacting couple for 80 longswings were produced. Graphical representations of coordination couplings are presented that include the traditional single coupling, followed by the relational dynamics of two couplings and finally three couplings simultaneously plotted. This method highlights the power of visualisation of movement dynamics and identifies properties of the global interacting segmental couplings that a more formal analysis may not reveal.

Uponor PEX plumbing systems' and their ability to withstand movement made for a perfect fit. This Tiny House on wheels may be small, but it is big on features. At a cozy square feet, the home is nothing short of luxurious, with high-tech building systems combined with high-end appliances and furnishings. Designed in collaboration with 30 architects, engineers, and materials specialists, this safe and sustainable home has helped educate and inspire over 50, people who have toured it since The homeowner, Tracey Powell, also happens to be its designer and builder. She and her brother, Trever Powell, wanted to ensure her home was safe, sustainable, durable, functional and technological. When it came to choosing a plumbing system to meet all of her needs, she first did her research, and then called Uponor.

Air is used as an energy source in almost every type of industry. It is an extremely efficient form of energy and is relatively inexpensive. It is easy to regulate and, when used with the proper equipment, is easy to clean and can be delivered relatively free of moisture, if necessary. Air, as it exists all around us, is at atmospheric pressure of When it is used as an energy source, it is compressed and delivered through a piping system or air hose to tool or other piece of equipment at pressures many times higher than atmospheric.
