Hysteresis is more than just an interesting oddity that occurs in materials with a first-order transition. It is a real obstacle on the path from existing laboratory-scale prototypes of magnetic refrigerators towards commercialization of this potentially disruptive cooling technology. Indeed, the reversibility of the magnetocaloric effect, being essential for magnetic heat pumps, strongly depen...

The hump characteristic is one of the major instabilities in pump-turbines. When pumpturbines operate in the hump region, strong noise and serious fluctuations could be observed, which are harmful to the safe and stable operations and even destroy the whole unit as well as water conveyance system. In this paper, a low specific speed (nq = 36.1 min−1) pump-turbine model was experimentally invest...

In this proposition, we present a link management technique for pro-active routing protocols for ad-hoc networks. This new mechanism is based on signal strength hence cross layer approach is used. The hysteresis mechanism provided by OLSR is improved upon by using signal strength in combination with the hello loss based hysteresis. The signal power is used to determine if the link-quality is im...

A method was devised for combining experimental partition coefficients measured at different temperatures into a single regression correlation. The proposed method described the 265 experimental air-to-polyurethane ether adsorption coefficients reported by Kamprad and Goss (Kamprad, I.; Goss, K.-U. Anal. Chem. 2007, 79, 4222-4227) to within a standard deviation of 0.084 log units, which is comp...

A simple adaptive MAC scheduling algorithm, called Gateway Oriented Scatternet Scheduling (GOSS), is proposed for data exchange in a Bluetooth scatternet. Unlike the existing scheme MDRP (Maximum Distance Rendezvous Point) that has a global superframe schedule shared by all gateways, the schedule used by each gateway is individually determined. Equal partition of the superframe schedule at a ga...

Material property evolution during processing is governed by the evolution of the underlying microstructure. We present an efficient technique for tailoring texture development and thus, optimizing properties in forming processes involving polycrystalline materials. The deformation process simulator allows simulation of texture formation using a continuum representation of the orientation distr...

Ultrasound imaging is increasingly used with motion and force data to quantify tendon dynamics during human movement. Frequently, tendon dynamics are estimated indirectly from muscle fascicle kinematics (by subtracting muscle from muscle-tendon unit length), but there is mounting evidence that this Indirect approach yields implausible tendon work loops. Since tendons are passive viscoelastic st...
