I do not think it matters, but I am interested in what it says (NPS vs NPS means nothing). Also, which IEEE journal is this, I assume the publication that goes to all members, however, there are several IEEE societies and each has a different tech journal. Do you have the month? Thanks in advance if you can supply this information. I will be a the library later this week doing part of a literature search and I may try to find this article (during a break).
