A system and method of scheduling tasks, comprising receiving activity and performance data from registers or storage locations maintained by hardware and an operating system; storing calibration coefficients associated with the activity and performance data; computing an energy dissipation rate based on at least the activity and performance data; and scheduling tasks under the operating system based on the computed energy dissipation rate.

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.

A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.

A microfluidic system for separating biological entities includes a cooling device including a thermoelectric heat pump, a first fan, and a first heat exchanger disposed between the first fan and the thermoelectric heat pump; a first housing structure having a first shell that encases the first fan and the first heat exchanger; a microfluidic device and one or more piezoelectric transducers attached thereto; and a second housing structure reversibly attached to the first housing structure and having a second shell that encloses therein the microfluidic device and the one or more piezoelectric transducers. When the first and second housing structures are coupled, a first air passage is formed between a side of the first heat exchanger and an end of the microfluidic device, a second air passage is formed between the first fan and the piezoelectric transducers, thereby allowing air to circulate between the first and second air passages.
