With the scaling down of the CMOS technologies, leakage power is becoming an increasingly important issue in IC design. There is a trade-off between subthreshold leakage power consumption and clock frequency in the circuit; i.e., for higher performance, leakage power consumption must be sacrificed and vice versa. Meanwhile, timing analysis during synthesis(More)
The study aims to estimate the ability of different grouping techniques on categorical response. We try to find out how well do they work? Do they really find clusters when clusters exist? We use Cancer Problems in Living Scales from the ACS as our categorical data variables and lung cancer survivors as our studying group. Five methods of cluster analysis(More)
The varicella-zoster virus (VZV) causes chickenpox or varicella, a disease primarily in children, and Herpes Zoster (HZ) or zoster or shingles, a disease that affects adults. A 2-dose Varicella vaccination is recommended in the United States, the first dose at age 15-18 months and the second dose at 4 to 6 years. In this study, we used multinomial logistic(More)
In today's emerging information systems, it is natural to have data distributed across multiple sites. We define a System of Databases (SyDb) as a collection of autonomous and heterogeneous databases. R-SyDb (System of Relational Databases) is a restricted form of SyDb, referring to a collection of relational databases, which are independent. Similarly,(More)
