25. Give an example of a nanomaterial that is >100 years old. 26. An ideal metal would be expected to expel electromagnetic fields (i.e. reflect EM waves). Why do some metals and metallic oxides have colour (even look black)? 27. How can a metal be modified to become black?28. What can be done to mitigate the effect of tunnelling across gate oxides in integrated microelectronics?
A Cypress Video Store (CVS) runs a series of fairly standard video stores. Before a video can be put on the shelf, it must be catalogued and entered into the video database. To rent a video, every customer must have a valid CVS customer card. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that he or she does not have any overdue videos. If so, the overdue videos must be returned and the customer must pay a fine before renting more videos. Likewise, if the customer has returned overdue videos, but has not paid the fine, the fine must be paid before new videos can be rented. Every morning, the store manager prints a report that lists the overdue videos.
Based on the readings and your research, select one program design technique of your choice (structure chart, Use Cases, ERD, and DFD). Using MS Visio software, create a diagram for the CVS system to process video renting activities. Copy and paste your diagrams into a Word document. Explain in a short paragraph why you chose this technique? Make sure you cite your sources with APA guidelines.
