Discrete & Continuous Data Definition & Examples Video

Discrete and Continuous Data. On the other hand, continuous data is data that can be divided infinitely; it does not have any value distinction. The amount of time it takes to sell the cupcakes is an example of continuous data. You can remember this by remembering that time itself is continuous and never ending.

Module 5 Nonlinear & Non-smooth Models solver

Non-smooth functions cause some difficulty, and discontinuous functions cause considerable difficulty, for most optimization algorithms if your model includes such functions you will likely have to settle for a "good" solution rather than a globally optimal one. In many business situations such a "good" solution is still extremely valuable, although of course a globally optimal solution is ideal.

Study on Rules of Fault Stress Variation Based on

Microseismic monitoring technology was used to study the real-time evolution of rock mass damage generated by a working face as it approached a fault in Dongjiahe Coal Mine. The influence of vertical zoning of overlying strata on damage at the fault was analyzed. Numerical simulation using finite element method based on meso-statistical damage theory was used to investigate the nonlinear and

Analysis of Highwall Mining Stability The Effect of

HWM has become a widely-applied method in surface mining, commonly used alone or in conjunction with contour or slot mining. It provides 800- feet to 1,200-feet of additional recovery when the economic stripping ratio is reached in contour mining or in slot mining when surface access to a reserve is limited.

Discrete and Continuous Data mathsisfun

Continuous Data. Continuous Data can take any value (within a range) Examples A person's height could be any value (within the range of human heights), not just certain fixed heights, Time in a race you could even measure it to fractions of a second, A dog's weight, The length of a leaf, Lots more!

What Are Some Examples of Continuous Variables

Full Answer. The other possible type of variable is called a discrete variable. This type of variable can only be certain specific values. For example, when flipping a coin, it can land either on heads or tails. There is no in-between value like 0.5 heads and 0.5 tails. With a continuous variable, the variable can be an infinite amount

What is the difference between alluvial gold and reef gold

What is the difference between alluvial and quartz mining? The word Alluvial describes a type of soil. It can be made up of sand, silt, clay, gravel, or other matter deposited by flowing water.


correlate (continuous lines) and the scatter allows for one to two classes difference between the two systems (dashed lines). This may be due to the definition of the classes. A more correct comparison between the two systems should be based on the recommended support for underground excavations.

BOLT SURFACE PROFILE Mining Science and Technology

It should be noted that the differences between the load bearing capacity between the 25 mm profile spaced Bolt Types T2 G1 and T3 is attributed to the surface roughness of the Bolt Type T2G1, which was resulted from the removal of the profile from Bolt TypeT2.

Detection of Overheated Rollers in Belt Conveyor Systems

conveying velocity and one roller of a large belt conveyor system from an opencast mining site. This roller is heated at its front surface and monitored at its shell surface by a thermal imaging camera. Fig. 3 shows the test mockup. Fig. 3. Test mockup of a belt conveyor system.


2.1 Standard Bucket Wheel Excavator Systems. Today, the classical excavators for continuous mining operations in open pits with cuttable material are bucket wheel excavators. As far as wear is concerned, the bucket wheel requires less maintenance than a bucket chain.

How to convert continuous variable to discrete in R?

Since you're providing the group variable with a numeric vector, this is understood as a continuous variable. You need to convert it to a categorical variable. Try the following The as.factor function will convert the numeric vector you provided for the groups to a discrete variable.

What are the main methods of mining? American

Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground.

Types of Production System Intermittent and Continuous

Feb 21, 2012 · In the intermittent production system, goods are produced based on customer's orders. These goods are produced on a small scale. The flow of production is intermittent (irregular). In other words, the flow of production is not continuous. In this system, large varieties of products are produced. These products are of different sizes.

Ventilation and Cooling in Underground Mines

Push-pull systems where both intake and exhaust fans are installed are used either to reduce the maximum pressure in the system by sharing or to provide a very small pressure difference between the workings and surface. This is pertinent in mines using caving methods where leakage through the caved area may be undesirable.

Sensors Different Types of Sensors

Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A sensor converts the physical parameter (for example temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically.Sensor can be defined as an element that senses in one form of energy to produce a variant in same or another form of energy.
