A fresh geometrical look at the general S-procedure
نویسندگان
چکیده
We revisit the S-procedure for general functions with “geometrical glasses”. thus delineate a necessary condition, and almost sufficient to have valid. Everything is expressed in terms of convexity augmented sets (i.e., via convex hulls, conical hulls) images built from data functions.

busy for most of the twentieth century. Policy after policy has been tried, rejected, then tried again in an attempt to solve the farm income problem. Ever since the New Deal, we have had price supports for many farm products. Since the Kennedy years, we have added direct payments to the relatively low price supports. All the while, supply control has been a part of most farm bills. None of thi...
متن کاملA fresh look at preoperative body washing
National guidelines do not support preoperative body washing to reduce surgical site infections, instead recommending bathing or showering with soap. Yet preoperative body washing continues to be widely used in many hospitals across Europe. This paper suggests that existing trials of preoperative body washing, upon which guidelines are based, are dated and proposes a new investigation of preope...
متن کاملA Fresh Look at Vocabulary Spurts
There is currently rather little agreement about the existence of, and explanation for, a vocabulary spurt in children during the second year. Here we apply a Functional Data Analysisbased technique called Automatic Maxima Detection to the problem of finding vocabulary spurts in a sample of 20 children. Even with considerable smoothing of the data, children were found to exhibit multiple vocabu...
متن کاملA Fresh Look at Generalized Veneziano Amplitudes
The dual resonance model, which was a precursor of string theory was based upon the idea that two-particle scattering amplitudes should be expressible equivalently as a sum of contributions of an infinite number of s channel poles each corresponding to a finite number of particles with definite spin, or as a similar sum of t channel poles. The famous example of Veneziano [1] satisfies all these...
متن کاملA Fresh Look at Heart Disease
According to the Centers for Disease Control and Prevention, “Heart disease is the leading cause of death in the United States and is a major cause of disability” (CDC, 2013). Research on heart disease has been ongoing for more than 50 years. Until recently, “the lipid hypothesis of heart disease has dominated medical thinking” (Fallon, Sally, & Enig, Mary, 2009). Cholesterol was found to be a ...
