torque, speed, and power as mechanical variables are associated with the functional performance of any rotating machinery. the real-time performance and the efficiency of a machine can be determined with on-line measurement of these parameters. in this investigation a rotary torque meter (transducer) was constructed from strain gauge sensors for measuring the torque of rotating shafts. the syst...

When a healthcare professional commits an error that results in an adverse patient outcome, it is increasingly considered appropriate that an apology should be made to the harmed person. 2 Such an apology benefits both the health professional and the patient, and serves to address the considerable emotional burden that accompanies this wrenching aspect of practice (see page 249). The process of...

This trip examines exposures in the Adirondack Lowlands that contain Paleozoic hydrothermal and faultrelated features hosted by Mesoproterozoic ‘Grenville’ marbles and Cambrian Potsdam Sandstone. These features have been the source of some debate historically and are now explicable as resulting from hydrothermal activity within an ancient wrench fault system. This system is similar to the deep ...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

A particle, shaped as an ellipsoid of revolution and rotating about an arbitrary axis, experiences a torque in a rarefied monatomic gas because of the impact with the gas atoms. This torque is calculated for the case where the linear dimensions of the ellipsoid are small compared with the mean free path of the gas. The interaction of the gas atoms with the ellipsoidal surface is taken into acco...

Hands have many joints in comparison with other parts of the human body. In the motor area of cerebral cortices related directly to sensation and movement, the area related to hands occupies a large part. This implies that dexterity of hands contributes to the development of the human brain. By virtue of the dexterity, hands have evolved to make tools and write pictures and characters. Especial...

The amygdala is clearly implicated in the processing of biologically relevant stimuli, particularly those that can lead to a state of fear. A new study by Herry, Bach and colleagues using both mouse and human subjects seemingly throws a wrench in the spokes by demonstrating that the amygdala is sensitive to non-biologically relevant stimuli (i.e. tones) when they occur in an unpredictable fashi...
