Fermion Fields, Boson Fields, and Gravitational Field
Annalen der Physik, 1976AbstractIf a tetrad theory is derivable from a variational principle with a Lagrangian ๐ of the form ๐ = ๐F+๐M 6 tetrad components will be defined by the vacuum equations if the energy momentum tensor is symmetric. Therefore, we look for a realisation of a programme proposed in a little different way by TREDER according to which the 16 tetrad field ...

Field emission, field ionization, and field desorption
Surface Science, 1994Abstract A brief description of the essential features of the theory of field emission, field ionization, field desorption, and the field emission and field ion microscopes is presented. The principal applications of field emission including work function and surface diffusion measurements, and a brief sketch of the theory of diffusion are also given.

Synthese, 1995
Hard-nosed physicists are content with elementary quantum mechanics as it is. Deep searchers desire a deeper comprehension of the theory or rather of reality. Observable internal correlations in micro-system and external correlations between widely separated parts can be calculated at the office.

Depth of field in light field rendering
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004This paper focuses on the sampling problem in light field rendering (LFR) that is a fundamental approach to image based rendering. Quality of LFR depends on a light ray database generated from pre-acquired images, since image synthesis is a process of gathering appropriate light ray data from the database.

We have now given two proofs of the Fundamental Theorem of Algebra. Both of these involved much more analysis (calculus) than algebra. The first relied on the analytic properties of two-variable real-valued functions from advanced calculus as well as the continuity of real polynomials while the second proof followed from the theory of complex analysis.

The electric and magnetic fields are easily derived from the vector potential using the relations $$\displaystyle \begin{aligned} \mathbf{E}(\mathbf{r},t)=-\frac{{\partial}\mathbf{A}}{{\partial}t}\\ \mathbf{B}(\mathbf{r},t)=\boldsymbol{\nabla}\mathbf{xA}. \end{aligned} $$

Introduction: Fields in transition - Fields in action
Poetics, 2009The manner in which cultural content is produced, evaluated, and consumed in society is subject to long-term as well as short-term changes. Building on Bourdieu's field concept, the six contributions to this special issue all seek to illuminate such changes, by analyzing the ways individuals and organizations act and interact in larger institutional ...

Abstract We shall now go rather more deeply into the theory of fields. In many ways a field is the best sort of system to work with, because it is always possible to divide by a non-zero element. The material of this chapter has many uses in the remainder of the book.

From field to Field (to field): An archaeological smorgasbord
2014This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by ...

In this chapter we begin to apply the stochastic limit to purely field theoretical Hamiltonians, i.e. fields interacting with other fields without any discrete system. The basic object to study in quantum field theory is the S-matrix introduced by Heisenberg.
