Centring is a commonly used technique in linear regression analysis. With centred data on both the responses and covariates, ordinary least squares estimator of slope parameter can be calculated from model without intercept. If subsample selected full data, typically uncentred. In this case, it still appropriate to fit intercept? The answer yes, we show that obtained intercept unbiased has smal...

Vulnerability in the interception of radar transmission by anti-radiation missiles or the like, can be avoided by using Low Probability of Intercept (LPI) techniques like Barker codes, Frank codes, polyphase codes, Costas code, etc. In this project, we simulate different kinds of complex waveforms that are obtained by superimposing LPI signal onto the radar signal. Analysis of the power spectra...

Arguments are presented for the odderon intercept being exactly equal to unity. A variational method is presented based on a complete system of onegluon functions. For the odderon, the highest intercept calculated by this method is 1− (3αs/π) 0.45. March 1996 hep-ph/9603218 US-FT/7-96 ∗ Visiting Professor IBERDROLA.

PURPOSE This study assessed test-retest reliability of an interviewer-administered trail survey. METHODS An intercept survey was conducted with adults using 2 paved trails in Indiana and South Carolina (N = 295; mean age = 46.9 +/- 18 y). The survey included items on frequency and duration of trail use for recreation and transportation, other patterns of trail use, and sociodemographic charac...

Cancer immunoprevention refers to the modulation of the host immune response to control the initiation or development of cancer. The significant role of host immunity in early tumorigenesis has only recently been confirmed, as a better understanding of the mechanisms, molecules and cells involved in tumor immunology have been elucidated over the past two decades. Of utmost importance, preclinic...

Rendezvous and intercept missions to smaller asteroids require precision guidance and control in the terminal mission phase. The zero-effort-miss (ZEM) and zero-effort-velocity (ZEV) information are used to formulate autonomous feedback guidance laws. A terminal-phase guidance strategy for a variety of intercept missions is developed. Different types of navigation information are assumed to be ...

in many applications the quality of a process or product is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. profile monitoring is used to understand and to check the stability of this relationship over time. therefore checking the capability of a profile seems essential. process capability indices have become very...
