INTRODUCTION TO MEASUREMENT WITH THEORY

Introduction to Antenna measurement Theory

The radiation field from a transmitting antenna is characterized by the complex Poynting vector E x H* in which E is the electric field and H is the magnetic field. Close to the antenna the Poynting vector is imaginary (reactive) and (E,H) decay more rapidly than 1/r, while further away it is real (radiating) and (E,H) decay as 1/r . These two types of fields dominate in different regions in sp...

An Introduction to Modern Measurement Theory

This tutorial was written as an introduction to the basics of item response theory (IRT) modeling and its applications to health outcomes measurement for the National Cancer Institute’s Cancer Outcomes Measurement Working Group (COMWG). In no way this tutorial is meant to replace any text on measurement theory, but only serve as a stepping-stone for health care researchers to learn this methodo...

Introduction to Model theory

These notes aim at giving the basic definitions and results from model theory. My intention in writing them, is that they should provide the reader with many examples, even with some proofs, and contain most of the definitions. Differences in vocabulary can be quite an obstacle to mutual understanding, and having the terminology written up somewhere should prove helpful. An index is included at...

Introduction to Queueing Theory

Introduction to Ergodic theory

Let Σ be a finite set. Recall from the previous setup that we have an abelian group G acting on the set Σ of functions G→ Σ. For a function ω ∈ Σ, this G-action is given by (g · ω)(h) = ω(g + h), h ∈ G For today, G = Z, the integers with the group operation of addition. We will think of Z as parametrizing the action of time. We set Ω := ΣZ. We would like to put an interesting metric on Ω, to st...
