Power-aware operating systems/processor controllers ensure that the system temperature does not exceed a threshold by utilizing system-throttling, where the clock speed is scaled to an equilibrium load. We denote this as the Constant policy, and compare against Zig-Zag policies that alternate between phases of cooling and heating. In this paper, we characterize and calculate the best possible Z...

Mesophilic bacteria, fungi and actinomycetes varied during composting cycles with high numbers in the initial and final cycles with maximal values in compost C and D, and sharply decreased in the heating cycles. Staphylococcus aureus and Bacillus subtilis were dominated at the initial composting cycle. Whereas, at maturity Bacillus subtilis was the major followed by B.badi...

In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...

This paper describes the implementation of long wave radiation (LWR) exchange as part of a co-simulation process of an urban scale simulation program, CitySim, and a building scale program, EnergyPlus. This coupling process was achieved through the use of functional mockup units (FMU) to exchange various weather, load, and environmental information between the two simulation engines. LWR is an ...

Accurate forecasting of thermal loads is a critical factor for operating district heating and cooling networks economically, efficiently with minimized emissions. If are known high accuracy in advance, use renewable energies can be maximized, fossil generation, particular peaking units, avoided. Machine learning has already proven to an efficient tool time series this context. One recent advanc...

To provide a reference for the renovation of Shanghai’s existing residential districts, this study quantifies and compares relationships between common strategies, microclimate, heating cooling loads. These strategies include improving greening rate (G), reflectivity pavement (P), wall materials (W), roof or applying green (R). are applied to typical model extracted from areas in Shanghai, Chin...
