This is the Estimation paperwhich is the value of the slope. Similarly, "Coulomb Counting" needs a way to calibrate its result, so that the charge it reports is the actual SOC. Example of estimated Li-Ion cell charge being much lower than what actual SOC; calibration Estimation paper charging when cell voltage crosses a threshold.

Overall, the function-points models appear to more accurately predict the effort needed for a specific project than LOC-based models. Extensions By using question 7 on the Measuring with Toothpicks student sheet as a class problem, students can practice their estimation skills.

What could we do if we needed to tell our friend what size our paper is, but we do not have our toothpicks with us? Students will first measure with the idea of units in mind and then be challenged to consider why it is important to have standardized units of measurement. As students are working on their toothpick measuring, they will likely Estimation paper to problem solve about what to do when their paper space is not equal to the lengths of their toothpicks.

Students do not need to be able to measure with these tools accurately, but this exercise will help students begin to see that different measuring tools are more efficient and easier to use with different objects.

If, for example, we tested four units that failed at 10, 20, 30 and 40 hours, then we would use these times as our x values or time values.

This position is consistent with that taken by those having done research in this field. If the SOC estibated through Coulomb Counting is uncalibrated it is not equal to the actual SOCeventually the battery will be charged or disccharged so far, that Voltage Translation can be used to estimate SOC, and cablibrate the estimate value.

You can help them recognize that using part of Estimation paper toothpick might help them solve this problem. The battery current is integrated "Coulomb Counting" to get the relative charge in and out of the battery The battery voltage is monitored, to calibrate the SOC when the actual charge approaches either end Combining Coulomb Counting and Voltage Translation to estimate SOC.

This is a simple method illustrating the idea. The operative word here is "relative": In the following applications, capacity measurement is not really possible: Either the data presented in Table 6 are incorrect, or the explanation of the variables given is such that I have been unable to fit the data to the model given.

The significant leakage current within Lead Acid batteries does not go through the battery current sensor and is therefore not taken into account Not all the charge in a Lead Acid battery is converted into useful work: What if you had to measure the length of a pencil?

The remarkable progress in improving child survival since has saved the lives of 50 million children under age 5. Toothpicks are a fun unit to start with. Still, 1 million children died in this age group in In the paper by Banker, Kauffman, and Kumar, it was made obvious that not only must the cost estimation technique be stable, but also the development tools must be stable.

For other creative ideas regarding estimation and measurement, see the following web pages: To use unconventional units of measure to estimate and measure. You can model this when you introduce measuring tools, and they will begin to incorporate the appropriate measurement wording as they experiment.

Have them come up with ideas of what to measure with and let them explore the classroom with these unconventional measuring tools.

Development Ask students what other things they could measure with. The times-to-failure, with their corresponding median ranks, are shown next: Drift can become significant in applications that, for long periods, use very little battery current or shuttle current back and forth: Coulomb Counting Integrating the current into or out of a battery gives the relative value of its charge, just as counting currency in and out of a bank account gives the relative amount in the account.

Ask the following questions: Should we consider that human behavior is a large factor in the software development process, and therefore in the cost estimation? At the same time, we can see that different companies, such as Anderson Consulting, offer cost estimation tools to their customers, and are highly "successful" at what they do.

We know that the cost of developing software, up until the point that it is accepted, is only a fraction of the total cost of the system over the typical life cycle of the product.

These and similar questions get at why standardized units are useful. Exposure to measuring in an exploratory environment familiarizes children with the concept of measurement and tools of measurement. As with any estimate, it is just that, an estimate.

All of these units fail during the test after operating for the following times in hours: Download the PERT estimating template Vendor Bid Analysis If there is a specific element of the project or all of the project to be outsourced and procuring an external vendor to deliver the project on your behalf, a simple and effective way in determining project estimates is to have these external suppliers conduct it on your behalf.Free Estimate Forms This page provides a compilation of different estimate forms available on various websites for free.
