# Formula Fusion ((EXCLUSIVE))

The purpose of this guide is to provide a reference guide to using Fast Formula in Absence Management. Fast formulas are generic expressions of calculations or comparisons that you want to repeat with different input variables. Fast Formula is a way to customize the existing functionality in Oracle Fusion Absence Management (as well as other Fusion HCM products).

## Formula Fusion

The examples provided are only for demonstration purposes to guide an implementer about the structure of the various formula types available in absences. They are not fully tested solutions, and must be adapted to meet specific customer requirements.

Fast formulas are considered a customization to the seeded application. Oracle support services will assist with troubleshooting formula issues, but Oracle Support Services is not responsible for writing any custom fast formula code.

The heat of fusion is the amount of heat that is released or absorbed to change the phase of a substance between the solid and the liquid phases. The heat of fusion occurs at a fixed temperature, the melting point.

The heat of fusion definition communicates a form of energy that is either released or absorbed when a certain amount of matter is changing phase. The heat of fusion is alternatively known as the enthalpy of fusion. The word enthalpy refers to the heat content in a defined system. When thermal energy is supplied to amount X of matter Y at a constant pressure, the enthalpy of Y changes consequently. The change in enthalpy to a specific magnitude result in changing the matter's phase. Supplying heat to ice would eventually lead to its melting; the energy that was used in expanding the ice molecules and transitioning water from the solid to the liquid phase is the heat of fusion.

In order to change a solid to a liquid, there is a certain amount of energy required. This is called the heat of fusion. Remember, fusion means melting, so you can see where it gets its name. Anyway, the heat of fusion is the amount of energy required to change a substance from a solid to a liquid at its melting point.

It's worth noting, it takes energy for something to melt, but energy is given off when something freezes. Also worth noting, there is a heat of solidification, which is the energy released when a liquid turns into a solid at its freezing point. Remember, solidification means turning a liquid into a solid, so you can see how heat of solidification gets its name. But, for now, the focus of your chemistry party is the heat of fusion and that melting ice cube, so back to that!

So, your ice cube melted and now you have a puddle of water on your kitchen table. You might be thinking your chemistry party is coming to an end, but don't worry! Things are about to get even more exciting. There is a formula you can use that involves the heat of fusion!

Since it is a chemistry party, I think we should try out this formula! Let's try to figure out how much heat energy was required to turn that ice cube into a liquid puddle at its melting point! In other words, we will use the formula to solve for q.

Where eqL_f /eq is the heat of fusion, Q is the amount of heat that is absorbed or released, and m is the mass of the matter that changed phases. The heat of fusion units is always energy unit per mass unit. The common units for each variable are as follows:

What I would like to do is use a rectangular pattern in a sketch to repeat a feature with a specific spacing. I wanted the pattern to start at offset X,Y from the top left corner of the parent sketch and extend to -X,-Y from the top right corner of the parent sketch. I could easily do that with the "Extend" pattern type and using the formula "(Width - (2*X))" as the distance.

However, when I tried to use a formula to compute the number of occurances, Fusion did not allow me to do that. The formula that I was trying to use was "(Width - (2*X))/5" (where 5 is the spacing that I wanted between occurances). I even tries using a user parameter and that did not work either.

If that is the case, this could get complicated in complex formulas, especially if you start mixing radii, or volumes, etc. I would think that it would be much easier for Fusion to provide casting operators. For example: int(Width + (2*X)) would result in a unitless value.

We discuss the applicability of the Wong formula for fusion cross sections in a single-channel problem. To this end, we carry out a systematic study and compare the approximate fusion cross sections with the exact results in a wide mass region of reaction systems. We show that the deviation of the approximate results from the exact cross sections is large for light systems, even though the Wong formula provides a reasonable approximation for heavy systems. We also discuss the energy dependence of the deviation, and show that for a given projectile nucleus the critical energy, at which the deviation exceeds 5% of the exact cross sections, increases as a function of the mass number of the target nucleus.

Comparisons between the exact (solid line) and approximate (dashed line) fusion cross sections for four selected systems. The approximate solutions are obtained with the Wong formula. The Akyüz-Winther potential is employed for the internuclear potential.

The deviation from the exact results, defined by Eq. (12), of the fusion cross sections obtained with the Wong formula. This quantity is plotted as a function of the mass number of the target nucleus for five projectile nuclei indicated in the figure.

Our formulas are packed with benefitial nutrients for your body. All of them are well known adaptogens and antioxidants, commonly used for positive physical effects such as enhanced mental focus, improved memory, improved alertness, and more.

The amount of heat gained by a solid object to convert it into a liquid without any further increase in the temperature is known as latent heat of fusion. The content of latent heat is complex in the case of sea ice because it is possible for sea ice and brine to exist together at any temperature and melt at a temperature other than 0oC when bathed in a concentrated salt solution, just like it occurs in the walls of brine cells when brine cells migration occurs. If m kg of solid converts to a fluid at a constant temperature that is its melting point, the heat consumed by the substance or the latent heat of fusion formula is expressed as

Finally, I found that brew was trying to move any dynamic libraries (dylib files) it found inside of the package to a common location. Brew is pretty aggressive about moving dylibs to a standard location, even though they are already portable binaries. This was spitting out a nasty looking error to anyone that installed the formula. Not what we want to see.

To solve this problem, I modified our Homebrew formula to tar up the dylibs from the Elasticsearch package during the install phase and extract them back out during post install phase. This ensured that brew stopped spitting out those nasty error messages.

During development I was able to test this using the following command, which allowed me to test the formulas locally without constantly iterating through Github. This command is very handy and allows you to avoid the cycle of push, test, debug and repeat:

After working though a few other minor issues, I ended up with a solid Homebrew formula that makes it simple to install and manage the FusionAuth files. I hope it works well for you, but let me know if you have any questions or issues.

Brew Tap: A source for getting formulas. By default the shorthand is / which equates to a github repo under /homebrew- that has a folder inside called Formula, which contains any number of Ruby files, each of which is an installable formula. A rough equivalent would be a ppa or apt repo.

This is the most basic state for a formula which contains meta data for description, homepage, and a download URL. The URL is also associated with a sha256 hash for added security. This is where our formula starts:

When Homebrew is installing the FusionAuth formula, it downloads the Ruby script above and stores it locally in a well known location. Then it executes the Ruby script to determine where to download files from using the url field of the class.

As mentioned above, we had to remove the dylibs in the fusionauth-search package to avoid having Homebrew move them into a different location. Here is the install function of the fusionauth-search formula with the code to remove the dylibs:

The post_install for the fusionauth-search on the other hand requires that we replace the dylibs we removed during installation. In order to replace the dylibs, we simply extracted the tar file that we created in the install function above. Here is the post_install function for fusionauth-search: 041b061a72
