It refers to Mean Absolute Deviation. It is the sum of errors divided by the sample size. It can be used in evaluating the accuracy of demand forecasting method by summing the differences between the actual demand and the forecast demand then dividing by the sample size. It is more convenient to use than the other method of evaluating the accuracy of forecasting method, which is Mean Squared Error (MSE). MSE is calculated by taken the sum of squared errors divided by the sample size. MSE uses the squared errors, which can enlarge the error values unnecessarily.
Brown and Gibson model of plant location?
These are meant to explain why plants grow in certain locations. You will be able find these models online.
Why it is necessary to temper hardened steel immediately after quenching?
to avoid the high internal stresses caused by quenching and to get tempered Martensite that is less brittle
Vent is an opening provided for gases to escape from the moulding box.
The gases are formed during solidification of the metal.i.e, when the metal is cooled ,the earlier high temperatures will lead to the formation of steam ,this steam is converted into gases to be escaped.
What is the difference between performance of 89c51 and 89s51?
The difference between performance of 89c51 and 89s51 is that the 89c51 has a standard 51 core. The 89c51 program cannot be directly ported to 51 compared to the 89s51.
How do you mould thermoplastic?
Thermoplastics is molded by first subjecting them to heat which makes them melt. In their molten state, they can then be molded to make the products of choice.
Which is the best resource for Abrasive waterjet cutting?
There are a few sites I would recommend. waterjets.org is a great resource for waterjet cutting. wjta.org is also good. wardjet.com has tons of information and videos about the waterjet cutting machines that they manufacture. Tryhttp://www.wardjet.com/waterjet-university.html
What type of brass are gears made of?
There are three types of brass that gears are made of. The three types of brass include: admiralty brass, Alpha brasses, and Alpha-beta brass.
Why pneumatic gauges are filled with glycerin?
Pneumatic gauges are filled with glycerin to dampen needle vibrations and fluctuations caused by rapid pressure changes, which helps provide more stable and accurate readings. Glycerin also acts as a lubricant, reducing wear on internal components and extending the gauge's lifespan. Additionally, the viscous nature of glycerin protects the gauge from external environmental factors, such as moisture and contaminants.
to increase the metallurgical quality of minerals for viable cost
What is plant utilization factor?
Plant Utilization usually is referring to the rate a plant is producing compared to what the plant actually could produce. (Ex.) Say a plant could produce 100 units in a year, however, management only decided to produce 70 units in that year....that year the plant was run at a 70% plant utilization
Why is blast furnace tapered from bottom of the furnace?
it is tappered to accomodate the gradual volume expansion of the solid charge as it descends through zones of Stack,from top to bottom in the stack the temperature gradually increases and we need to ascertain smooth burden descent.
I don't know the regulations, but I would say that if it was on purpose, then yes, if not, then it was just a simple mistake. If he were to be charged with the victims death, I would say murder if he intentionally connected them, and manslaughter if it was an accident/mistake.
Can the condenser approach be a negative number?
Yes, the condenser approach, which refers to the temperature difference between the condensing fluid and the ambient environment, can be a negative number. This occurs when the condensing fluid is cooler than the surrounding environment, indicating that heat is being absorbed from the surroundings rather than released. Such a scenario can impact the efficiency of heat exchangers and condenser systems, potentially leading to operational challenges.
