Abstract: An example assembly includes an equipment room, a cabinet fan module having fans, and a processor configured to execute logic. Temperature sensors are positioned in the air inlet channel and the equipment room. An electrical component having an air inlet area is also positioned in the equipment room. The logic causes the fans to operate at a predetermined speed, and compare a temperature in the air inlet channel with a temperature at the air inlet area. In response to determining that the temperature at the air inlet area is greater than the temperature in the air inlet channel plus a constant value, the operating speed of the fans is increased. Moreover, the operating speed of the fans is decreased in response to determining that the ambient temperature in the air inlet channel plus a constant value is greater than or equal to the temperature at the air inlet area.

Abstract: A method for extracting future performance indication from historical daily returns, instead of annual or monthly returns, by utilizing probability-weighted net-profit-to-loss ratio. It often begins with reorganizing raw results into individual daily returns. To simplify the calculations, the method avoids directly calculating with corresponding underlying probabilities. Instead, it reduces computing components of the ratio to straightforward sums of daily gains and losses that actually reflect the weighting effects by their underlying probability. Thus, future performance indication is extracted from the calculated ratio, determining if an investment strategy may statistically outperform a predetermined benchmark or generate positive net profits.

Abstract: The present embodiments relate to a tunnel magnetoresistance (TMR) element. The TMR element can include a free layer comprising a metallic alloy that is doped using a dopant element. In some instances, the metallic alloy comprises a cobalt-iron (CoFe) alloy. The present embodiments relate to doping a small amount of an element (e.g., hafnium (Hf), tantalum (Ta), Yttrium (Y)) in a high flux CoFe layer of a tunnel magnetoresistance (TMR) element. The small amount of dopant can suppress a long-range order in the CoFe film. The amorphous state of a CoFe alloy can be induced by the dopant and result in a magnetically soft layer. A resistance of the TMR element can be modified based on an application of an external magnetic field to the free layer and the pin layer.
