Log-normal distributions are often used in probability theory to predict the distribution of a random variable. This type of prediction can be used in various fields, such as the financial investing field, to calculate the potential value of whatever the variable happens to represent. In investing, for example, log-normal distributions are used to predict stock prices within a specific range of possibilities. For example, if the price of a stock fluctuates from one day to the next, the log-normal distribution of the ratio of the stock's prices may be said to be nearly equal with the ratio in the change…
Aggregate functions are a handy feature of Structured Query Language, and include mathematical operations that compute maximum, average and total values, among others. As the term implies, an aggregate function operates on an entire set of data, returning a single value regardless of the number of records you select. Though you most often see aggregate functions in the main part of an SQL statement, you can use them in subqueries also.
An antenna feed line connects a radio transmitter or receiver to an antenna. The distance depends on the physical relationship between the two and the objects that may obstruct running the cable. One of the most common mistake engineers and ham radio operators make is to assume the necessary length equals the distance from the transmitter to the tower plus the height of the antenna on the tower. After ordering the cable, they find out that they must circumvent one or more objects and don't have enough. Because feed line cable is difficult to splice, many such mistakes can be…
Charge parity, or C parity, is an important concept in quantum mechanics because it describes the behavior of particles that are performing oscillatory motion. It’s a multiplicative quantum number. Although, each electron has its own set of four quantum numbers, you only need to know its angular momentum quantum number, which labels the spin or angular momentum of an electron, to measure its charge parity.
GPS surveying uses Global Positioning System technology to determine geographical and structural measurements as they pertain to various development projects, such as roads and construction.

A ring network is one that connects one node or station to at least two others. These connections create a contiguous stream of data, with all nodes connected to one another. Each subsequent station serves to boost or repeat the signal as it travels around the ring, forming a stable level of performance. Although the distances between each node on the ring will differ from environment to environment, there are limitations involved.
