According to the hysteresis curves (Dunlop, 2002), the presence of pseudo single domain (PSD) and multidomain (MD) magnetite has been estimated (Figure 6b). One site showing Cure temperature of approximately 320°C may actually indicate existence of pyrrhotite or gregite (LM29 in Figure S1).

What is Hysteresis? K. A. Morris Hysteresis is a widely occuring phenomenon. It can be found in a wide variety of natural and constructed systems. Generally, a system is said to exhibit hysteresis when a char-acteristic looping behaviour of the input-output graph is dis-played. These loops can be due to a variety of causes. Fur-

Other articles where Hysteresis loss is discussed: hysteresis: …which is known as the hysteresis loss, in reversing the magnetization of the material is proportional to the area of the hysteresis loop. Therefore, cores of transformers are made of materials with narrow hysteresis loops so that little energy will be wasted in the form of heat.

b GEMSE, 283 rue de la Minière, 78530 BUC, France Abstract We present a method for fully automatic 3D reconstruction of coronary artery centerlines using three X-ray angiogram projections from a single rotating monoplane acquisition. The reconstruction method consists of three steps: (1) filtering and segmenting the images

Mountaintop removal coal mining (MTM) is a form of surface mining where ridges and mountain tops are removed with explosives to access underlying coal seams. The crushed rock material is subsequently deposited in headwater valley fills (VF). We examined how this added water storage potential affects streamflow using a paired watershed approach consisting of two sets of mined and unmined ...

hysteresis loop. Consequently, the hysteresis loop may yield information on fatigue degree, as well as a stress-strain characteristic curve. Theoretically, bearing steels are considered to have a linear characteristic both under normal stress, σ, and shear stress, τ, loads. Practically, these materials display hysteresis even in elastic range ...

Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past.Plots of a single component of the moment often form a loop or hysteresis curve, where there are different values of one variable depending on the direction of change of another ...

Hysteresis curves of the first type for the samples from the western part of the pluton present ferromagnetic sensu lato minerals with magnetic saturation at about 300 mT (Figures 8a and 8b). This shows the presence of magnetite as a significant magnetic mineral.

The customer wanted to replace an existing bronze bushing with a longer-life, maintenance-free product. Solution - HiMod The HiMod® bearing extended the life and reliability of the equipment and increased the length of time between preventive maintenance procedures.

Fig. 3(a) shows the stress–strain curves of preforms 15/700/0, 15/800/0, 15/800/240, 15/800/600 and 15/900/0.The strength of the preforms much increases with increasing sintering temperature or sintering time. During tensile testing, specimens 15/700/0 and 15/800/0 exhibited a quite large swelling in the direction perpendicular to the fibre layers.

Hysteresis definition is - a retardation of an effect when the forces acting upon a body are changed (as if from viscosity or internal friction); especially : a lagging in the values of resulting magnetization in a magnetic material (such as iron) due to a changing magnetizing force. How to use hysteresis …

AbstractRock fracture due to high-pressure fluid jetting and insert indentation was experimentally investigated. In the frame of this article, indentation designates the process of pressing a tungsten carbide insert (TCI) for roller cone bits displacement-controlled into the rock surface. Under atmospheric conditions, several crystalline and one sedimentary rock type were tested.

Hysteresis, lagging of the magnetization of a ferromagnetic material, such as iron, behind variations of the magnetizing field. When ferromagnetic materials are placed within a coil of wire carrying an electric current, the magnetizing field, or magnetic field strength H, caused by the current forces some or all of the atomic magnets in the material to align with the field.

The hysteresis typical for spool valves during operation is very low with the PSL-CAN Lite. The entire valve bank is connected to the bus system of the machine with only one connector plug. This keeps the cabling effort very low and shortens the commissioning time.

Hysteresis provides a few key benefits to you and your air conditioning and heating system: It saves your HVAC system from undue wear and tear – anyone who has worked with cars or other machines, knows that start-up is the most stressful time on your system. By decreasing the frequency with which this happens, you decrease wear and tear on ...

Hysteresis, or bang-bang, control is perhaps the simplest control loop to implement. 83 With a hysteresis loop, the plant is operated in either of two states: off or on. A hysteresis band is defined, and if the feedback signal is above that band, the plant is operated in one state; if it is below that band it is operated in the other state.
