Deep energy retrofit (DER) of the existing building stock is a meaningful strategy to reduce fossil fuel consumption and CO2 emissions. However, the invest
Today we are launching newT2instances forAmazon EC2. The T2 instances will dramatically reduce costs for applications that can benefit from bursts of CPU power. The instances are available in three sizes (micro,small, andmedium) with On-Demand prices that start at $0.013 per hour ($9.50 per ...
You make good points, but at some point, Apple has to move back to a single platform again if it wants to stay ahead of the development curve. Making Snow Leopard for both Intel and PPC would be a HUGE undertaking; they've already slowed down the upgrade cycle from one version to ...
It is common for civil structures to have large numbers of sensors installed for structural health monitoring (SHM). In fact, [7] noted that it was not uncommon for a single civil structure to have hundreds or even thousands of sensors. This tendency is again evident in previous studies, ...
a system which can simultaneously scan multiple Data Matrix codes and autonomously introduce them into an authentication database is proposed for the Hospital Pharmacy of the Centro Hospitalar de Vila Nova de Gaia/Espinho, E.P.E. Relevant features are its low cost and its seamless integration in...
Figure 7. Evolution of temperature and humidity during a week for the tested interpolation time windows: (a) 10 min; (b) 30 min; (c) 1 h; (d) 2 h. When interpreting these results, we need to consider that the air quality control system did not try to control the temperature and...
The low BOS estimates relative to the NREL BOS model (Table 3) may be a reflection of moderate water depths for most UK offshore wind farms compared with those expected in the US [6]. Table 3. CAPEX estimates in US $ million per MW of installed capacity from previous work along with ...
Significant amounts of waste heat are deposited in greywater, which can be utilized, among other things, for heating domestic hot water in residential buildings. The manuscript presents an economic analysis of a greywater heat recovery system using a vertical heat exchanger of the “tube-in-tube...
. The results provide a comprehensive review of the European progress towards cost-optimality in both the residential sector (average cost-optimal level 80 kWh/m2y for new, 130 kWh/m2y for existing buildings) and the non-residential sector (140 kWh/m2y for new, 180 kWh/m2y for existing ...
Hence, it is important to explore the cost breakdown of wave energy by the wave energy converter (WEC), so for finding potential ways to decrease the cost, and finally compare it with other renewable energies. Different WECs have been installed in the same place; the Wave Dragon LCOE ...
