A method for controlling a data center, comprising a plurality of server systems, each associated with a cooling system and a thermal constraint, comprising: a concurrent physical condition of a first server system; predicting a future physical condition based on a set of future states of the first server system; dynamically controlling the cooling system in response to at least the input and the predicted future physical condition, to selectively cool the first server system sufficient to meet the predetermined thermal constraint; and controlling an allocation of tasks between the plurality of server systems to selectively load the first server system within the predetermined thermal constraint and selectively idle a second server system, wherein the idle second server system can be recruited to accept tasks when allocated to it, and wherein the cooling system associated with the idle second server system is selectively operated in a low power consumption state.

Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material.

A panning tool is described and comprises a sifting scoop comprising an elongated half sphere of proportional dimensions. The left side wall, right side wall, and back wall of the sifting scoop define a reservoir for collecting sediment and holding precious metals and gems separated from the sediment during and after panning. The floor extends forwardly from the back side and can comprise riffles, furrows, or be flat. The panning tool comprises a connection body. The connection body is affixed to an interior face of the sifting scoop. Methods of using the panning tool and manufacturing the sifting scoop are also described.

A system and method for selectively filtering abrasive particles for a cutting machine serves to filter variously shaped and dimensioned abrasive particles into a hopper through use of multiple, interchangeable screens. Each screen forms multiple openings defined by a shape and dimension, and each screen has a unique shape and dimension. A pneumatic variable speed motor vibrates the screens at variable speeds, depending on intensity of air flow through an air inlet. The sieve subassembly has a main base and containment ring. A two-piece split clamp ring sandwich the perimeter region of screens. From the hopper, a flow of high-pressure air carries the filtered abrasive particles to a waterjet cutting machine. The filtered abrasive particles are mixed with high pressure water to cut a workpiece. The shape and dimension of the abrasive particle is determinative of the type of workpiece to be cut.

A panning tool is described and comprises a sifting scoop comprising an elongated half sphere of proportional dimensions. The elongated half sphere can be a one-piece main body comprising a floor with a front edge, a left side wall curving upwardly along the floor's left side, a right side wall curving upwardly along the floor's right side, and a back wall curving upwardly from the floor's back side. The left side wall, right side wall, and back wall define a reservoir. The floor extends forwardly from the back side. The panning tool comprises a connection body. The connection body is affixed to an interior face of the sifting scoop. Methods of using the panning tool and manufacturing the sifting scoop are also described.

In a processing tank where a processing liquid is stored up to a first water level, first stirring processing that removes water from a used paper diaper is performed to remove the water from the used paper diaper. Then, the processing liquid is stored up to a second water level higher than the first water level, and second stirring processing that separates excrement contained in the used paper diaper from the used paper diaper is performed to separate the excrement from the used paper diaper. After that, dehydration processing is performed.
