The tricky part becomes the fact that in order to block/contain sound, the product that you use between the noise source and the ear needs to have as much mass and density as possible. I wouldn’t want to make
On postnatal day 60, the F1 offspring were tested for anxiety-like behavior first by elevated plus-maze (EPM) and then by open field test (OFT) one week later. Offspring from matings between unstressed parents constituted the controls. During EPM, the level of anxiety was quantified by the...
A0 (B0) is the intersection point between the plumb line passing through A(B) and the geoid, A′ is the intersection point between the plumb line A0A and the equi-geopotential surface WB. From formula (1), the clock-comparison-determined geopotential difference ΔWAB(T) between stations A...
The results indicate that gender and residential type exert certain influence on the elderly’s visual impact assessment of pocket park landscape. To be specific, the male elderly prefer the pocket park landscape with 3-6 m high trees, medium green space ratio, and more leisure facilities; the...
Conversely, the blue, green and red ETM + band spectral response functions intersect with 98.83%, 98.30% and 98.90% of the corresponding OLI band spectral response functions. Notably, the OLI near-infrared (NIR) band (~ 0.85 μm) avoids a water absorption feature that occurs in the ETM +...
The difference between the air flow screen and other screening machines: the airflow screen is a new type of screening equipment, which is mainly designed for screening highly refined powder materials. Because of its small size, stable operation, noiseless, ...
We’ve created a profile with 140 cd/m2 luminance, D65(6500K) white point and 2.2 gamma.We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc. You can check out the results at factory condition and...
Our emphasis was to understand both the differences among algorithms with changes in parametric conditions, and also the effects of these parameters on performance for each algorithm. Our results show dramatic interactions in performance both between and within algorithms under different parameters, some ...
For the most part, digital sensors are built around a similar concept, even if there are differences in the chip construction. The imager features light-sensitive photosites and a filter with repeating patterns of red, green, and blue squares adding color. Most sensors use a 4-by-4 Color ...
Time of Arrival (ToA) systems measure the propagation time of a signal between the transmitter and receiver to compute the distance from a particular transmitter. For this technique, all nodes need to be synchronised to a single reference time which can be difficult or impossible for simple devic...
