A handheld fan, or simply hand fan, may be any broad, flat surface that is waved back-and-forth to create an airflow. Generally, purpose-made handheld fans are folding fans, which are shaped like a sector of a circle and made of a thin material (such as paper or feathers) mounted on slats which revolve around a pivot so that it can be closed when not in use.

The simplest AFPM machine structure uses an annular, slotted (or slotless) stator, containing the radially-arranged armature windings, and a disk-rotor, carrying PMs that produce the axial flux. The AFPM machine has a larger diameter-to-active-length ratio compared to its radial-flux PM counterpart. As a consequence, when the number of

In order to define optimal process parameters, according to the characteristics of the different continuous casting machines, and to optimize the revamping of older equipment, thermomechanical modelling of the steel slab behaviour during casting has been carried out.

Social sciences. In the social sciences an open system is a process that exchanges material, energy, people, capital and information with its environment. French/Greek philosopher Kostas Axelos argued that seeing the "world system" as inherently open (though unified) would solve many of the problems in the social sciences, including that of praxis (the relation of knowledge to practice), so ...

The rotational speed and the feed speed affect the most the surface quality. To obtain good surface quality for consumers, the rotation speed should be greater than 5000 rpm, with a maximum feed rate per tooth of 0.5 mm, and a maximum average chip thickness of 0.18 mm. This knowledge will help industries to better optimize the cutting of wood.

The present article addresses positioning of a flat end milling cutter to ensure avoidance of local and global interference. The activity concerned is end milling of parts modelled by free-form surfaces on 5-axis Numerical Control machines. The tool positioning defined here uses two corrective angles and thus takes full advantage of all the possibilities for 5-axis machine movement.

Machining by parallel planes is a widely used strategy for end milling of free-form surfaces on 3-axis Numerically Controlled (NC) machine. In industry, this type of machining is generally performed with a hemispherical tool. However, numerous studies have shown the benefits of torus end mill on ball end or flat end mills. More than anything, the machining direction has much influence on ...

Electromagnetically induced acoustic noise (and vibration), electromagnetically excited acoustic noise, or coil whine is audible sound directly produced by materials vibrating under the excitation of electromagnetic forces.Some examples of this noise include the mains hum, hum of transformers, the whine of some rotating electric machines, or the buzz of fluorescent lamps.

However, the results presented in this paper should convince that for free-form surface machining appli-cations, even compared to the advanced B-Spline ...
