Thermal effectiveness of different attachment systems for exterior insulation [Chart from RDH Building Science report; link below] The takeaway here is that exterior insulation by itself isn’t going to be a game changer. You’ve got to pay close attention to the attachment system. Also, the bu...
Chart: Switching from single- to double- or even triple glazing can make a big difference (darker blue), especially if you use low-e, heat-reflective glass (lighter blue). The numbers shown are R-values, with a 0.5 inch air gap. Curtains and blinds If you can't insulate your windows...
Figure 3. Flow chart of the dung beetle optimization algorithm used to optimize the hyperparameters of the AE-GATv2 model. 4. Results 4.1. Experimental Data An experiment was designed to verify the CVT internal insulation abnormality online evaluation method based on self-supervised learning. In ...
Figure 10 presents the Ka values as a function of temperature for the PTK 52 kV bushing. The absorption coefficient ranged in value from 0.7 to 0.98, which means that, for a temperature of ∆T = 95 °C, the relative changes of Ka amounted to around 40%. Considering that the impact ...
The noise reduction coefficient (NRC) is determined by calculating the average value from the one-third octave values of the SAC at frequencies of 250, 500, 1000, and 2000 Hz and rounding the result to the close 0.05 following [46] and [25], as shown in Table 6. Figure 15 shows a ...
