A hash function maps keys to small integers (buckets). An ideal hash function maps the keys to the integers in a random-like manner, so that bucket values are evenly distributed even if there are regularities in the input data. This process can be divided into two steps:1  Map the key to an integer. hash function maps keys to small integers (buckets).

This process can be divided into two steps:
Electrical energy consumption were measured as 0.001 kWh for 5 C, 4 C, and 3 oC and 0.003 kWh for 2 C, 0.006 kWh for 1 C, 0.001 kWh for -1oC, 0.109 kWh for -2oC and 0.120 kWh for -3 C. Mean. energy consumption of the compressor was 0.035 kWh/ oC for positive cold storage temperatures (from 5 C to 0oC) and 0.093.
The downside is that the system remains pricey. For an average home, the battery storage system can run $10,000 to $25,000. But with long-term financing options and declining solar photovoltaic prices, the cost can end up penciling out at a price that's competitive with electricity from HECO, said Saturnia.or an average home, the battery storage system can run $10,000 to $25,000.
