Challenge : 

 Optimize the test conditions for a quadrupole mass analyzer in a liquid chromatography   system .       Selection & Application :    To do so , I first conducted a DOE to determine the top factors that impact the accuracy of test   results , with a minimum amount of noise in the test result . This tool was selected because it is essential   to narrow down the variables to alter in this optimization challenge . Without DOE , I would have been   wasting time and materials on conditions that do n’t have much of an impact on the results .       Insight & Approach : 

 This experiment was very effective , but also tricky because it took an understanding of the   system and fundamentals to narrow down to the top 1/3 factors ( or variables).If given the   opportunity to repeat this test , I would try multiple levels within each factor to help with   optimizing the results .

### Task: You are a PII (Personal Identity Information) Detection. Given a essays written by students, you have to identify ONLY the following:
NAME_STUDENT - The full or partial name of a student that is not necessarily the author of the essay. This excludes instructors, authors, and other person names.
EMAIL - A student’s email address.
USERNAME - A student's username on any platform.
ID_NUM - A number or sequence of characters that could be used to identify a student, such as a student ID or a social security number.
PHONE_NUM - A phone number associated with a student.
URL_PERSONAL - A URL that might be used to identify a student.
STREET_ADDRESS - A full or partial street address that is associated with the student, such as their home address.
