Is your year-end bonus dragging you down? Internet industry squeezed into the top three China News agency, Beijing, February 7 (reporter Ma Yi) Although Chinese white-collar workers reflect the general shrinkage of the 2015 year-end awards, there are still big differences between the different industries. A recent year-end award survey by an agency showed that the highest sectors, such as the financial sector, were nearly twice times more than the le

on the ground. Integrated GPS Positioning requires the built-in GPS module of the mobile phone. However, this module only has the receive function and does not have the launch function. 24 GPS satellites are constantly transmitting information containing time, satellite points, and other important parameters to the earth. After receiving the information from our mobile phone, the mobile phone calculates the distance from the mobile phone to each

big databases are commercialized, for example, a large number of databases exist in science and engineering. These databases are usually associated with the computer's automatic receipt data, for example: . Astronomical (sky chart) . Meteorological (climate and environmental pollution monitoring station) Satellite remote sensing . High-energy physics . Industrial Process Control This data can also benefit from the data mining technology (in principle

observation technology makes the sensor species more and more, the accuracy is more and more high, the information is more and more abundant. For example, three-dimensional laser scanning system, can get 1 million points of data per second, the information obtained in addition to the target object's spatial coordinate information, there are reflectivity information and texture information (Bin Li, 2012). In addition to the existing mapping geo-information data, human data sources now include a

Access network refers to the "user interface and Business node interface between the implementation of the host function of the entity." Access network basically includes transmission system, multiplexing equipment, user/network interface, digital crossover equipment, etc., usually access network transmission system according to the transmission medium into wired access and wireless access. Wireless access technology has a variety of classification methods, according to the transmission rate, th

We conducted organizational design and human resources system changes for an enterprise. During management diagnostics, we found that the company has the following Architecture: President, Executive President, and executive vice president. According to our function analysis, the chief executive officer here is basically an "empty bird cage", but this position has bee

Pdop: Position dilution of precision. It is translated as "precision intensity" and is usually translated as "relative error ". The specific meaning is: because the quality of the observed results is related to the geometric shape between the measured man-made satellite and the receiver, therefore, calculating the error volume caused by the above is called the strength of accuracy. The better the satellite

Some of heard this term when ordering imagery from Apollo Mapping or perhaps when downloading free Landsat da Ta without understanding its implications. As such, let's delve into this topic, addressing the following set of questions:What exactly is the bit depth and why are it important
