The tools are moving average‚ weighted moving average and exponential smoothing. The moving average takes the total of actual demand for previous months then divides by the number of months added. The number of months that is used can be predefined such as using the previous three months. This is the simplest and easiest calculation but often is not accurate since it can have a lag in spotting trends (Murphy). The weighted moving average is similar to the moving average but it places weights

speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has a fixed shape in which a certain the substrate will fit into. The sequence of the amino acids in the enzyme determines

Abstract I found that this experiment gives me an understanding on how osmosis and diffusion works. In its simplicity‚ it explains the process that our bodies (mainly cells) use all the time. It also showed me that even with the temperature changing‚ it doesn’t drastically change the rate of diffusion. Introduction Diffusion is important in all living systems. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

Not Your Average Theatre Kid I am a shy person. Teachers seem to love me since I stay quiet in class and I do my work. I hear drama left and right about this student and that student. I am a quiet person. Except when I am on stage. I am a different person when I am on stage. I am loud and I am proud. I am able to leave the shy girl. I might not be the best actor‚ and I might not be someone who gets the lead roles and speaking parts. I found my confidence in theatre. I found happiness through theatre

That was the inferred hypothesis. The method used to gather the information was a pretest-test-posttest study design and the sample consisted of 48 full-term infants. The key findings showed most infants reached and maintained temperatures between 36.5 and 37.6 degrees Celsius‚ the thermo neutral range‚ with only

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in

maintain a “C” grade average in school before receiving a driver’s license. Some people think this would be a good policy because having a passing grade shows that students are responsible enough to be good drivers. Other people believe that the policy wouldn’t be appropriate because they see no relationship between grades in school and driving skills. I believe that students should maintain a “C” grade average.
