, physical structure and Moore's law interpretation, which makes me understand the basic structure of the computer, deepened the understanding and understanding of the computer. After introducing us to bits, bytes and information representations, this chapter gives me an idea of what I have never known before, such as the red liquid of a thermometer or the mercury column being simulated: the liquid expands or contracts proportionally with temperature
concept, the results went to the nearest gas station, and the video on the poor, here the device can not measure the pressure, asked the next, looking for a gas station shop to borrow a tire pressure, thinking how tall equipment, the results looked like a thermometer. There is the maximum pressure on the tyre, the inside of the driver's door has a recommended pressure, thanks to an American lady reminding me, or I will add the maximum pressure on the
of moisture on the wet bulb surface, the less the wet bulb temperature drops, the smaller the temperature difference between wet and dry balls. Of course, the temperature difference between wet and dry bulb is also related to other factors, such as Wet ball size, wet ball wetting method and so on. According to the temperature value of wet and dry bulb, and some other factors are taken into account, the air humidity at that time can be calculated theoretically. The wet and dry bulb

temperature value is: 73.8 ℃Using the infrared thermometer to measure about 73.2 ℃, considering the various aspects of the error, we can roughly verify that we should use the average voltage collected by Pt100 as the actual temperature corresponding to the voltage value. (In fact, this should not be difficult to understand, this is an indicative voltage, not the heating voltage, so the effective value (power) to indicate the less reasonable)Two: The

errors will be magnified. To be precise, scientists must optimize the measuring tools. That's how modern science is developed, says physicist Kelvin (international Unit of temperature): "Measurement is cognition". Many good scientists must be able to collect and manage data accurately.in the "Big Data" era, the use of all data becomes possible, and usually tens of millions of data, to ensure that the accuracy of each data is unthinkable, the confounding is unavoidable. However, when the amount

7. Canvas GaugesCanvas Gauges is a fully customizable instrument made from plain JavaScript and HTML5 canvas (canvas) that you can use to create measuring devices such as speedometer, thermometer, etc.Because it has a small amount of code and is not dependent on it, it is also suitable for IoT devices. You can learn about it by using
, they are widely used. For example, when we say normal body temperature is 98.6 (Fahrenheit), it does not need to be accurately expressed if the thermometer shows 98.6 degrees. It could actually be 98.5999473210643 degrees. This shows that 98.6 is sufficient for most applications.Another way to get a floating-point number is through division. 10 divided by 3 to get 3.333333 ..., is an infinite loop of small compress. The computer allocates only a fix

(4) Assuming that the most nodes in the implied Markov chain have a D node, that is, the width of the entire grid is D, then any step of the complexity is not more than O (D2), because the grid length is N, so the complexity of the entire Viterbi algorithm is O (N· D2).
Concise Example1. Topic Background:Once there was a village where people in the village had only two possible physical conditions: health or fever.Assuming that the village's people do not have

Well, it's going to be pretty easy to realize.

If the thermometer in the weather station doesn't read the temperature, then your database will store a null value instead of a 0. Obviously, a value of 0 is entirely another matter.
