the largest structure in the known Universe, but on its own, it isn't much to look at. Meaning "northern crown" in Latin, Corona Borealis is a semicircle of mostly dim stars that wouldn't catch your
A-weighted decibel (dBA or dB(A)) is an expression of the relative loudness ofsoundsas perceived by the human ear. A-weighting gives more value to frequencies in the middle of human hearing and less value to frequencies at the edges as compared to a flat audiodecibelmeasurement. A-weightin...
Laser safety is an important topic. Everybody working with lasers has to follow the long-established occupational safety rules to prevent people from eye damage by accidental irradiation. These rules comprise, for example, the calculation of the Maximum

In 1995, building on earlier work by Bourgain, Wolff famously obtained (1) with using what is now known as the “Wolff hairbrush argument”, based on considering the size of a “hairbrush” – the union of all the tubes that pass through a single tube (the hairbrush “stem”) in ...
(e.g.15 kPa,44 kPa and 55 kPa for linear,circular and logarithmic spiral failure surfaces,respectively),the safety factors of slope with three different failure surfaces are less than the one that did not consider the tensile failure.The most critical failure surfaces of the slope may be ...
In nature, there are numerous examples of number sequences, such as the logarithmic spirals of shells and sunflowers or the mathematical sequence of the arrangement of leaves on stems. Understanding the structure and beauty of the natural world is made easier by the underlying mathematics....
complementing each other and complementing the green plants in the windows, making the space more ethereal.Lifud 0-10V C.V. dimming driver of GDE-YV series, with logarithmic and linear dimming selectable, is perfectly compatible with mainstream dimming systems in the market, and its 93% ultra-...
An earthquake is the abrupt and violent shaking of the crust of the Earth as a result of the movement of the fault lines. A fault line is a break or fracture along the Earth's crust. The violent shaking experienced during an earthquake is due to the seismic energy that was rel...
sides! His tombstone contained his upper and lower bounds for pi. The original tombstone disappeared some time around 1800; a replica is shown below. Jacob Bernoulli—logarithmic spiral Bernoulli was so enamored with the logarithmic spiral that he wanted it engraved on his headstone. However, the...
