Ethnography at its edges: Forces in the wind

American Ethnologist, 2016
ABSTRACTIncreasingly, anthropologists are using art practices to represent their work and, with this shift in media and style, reach out to new audiences in the process. In Aeolian Politics, Cymene Howe and Dominic Boyer collaborated with Ethnographic Terminalia to outfit a two‐room cottage with video footage, turbomachinery, poetry, and supplementary ...

The edge force components in oblique cutting

International Journal of Machine Tools and Manufacture, 1990
Abstract It is shown that in an oblique cutting operation two of the edge force components can be derived on the basis of the hypotheses: (a) that there exists an equivalent orthogonal cutting operation which is such that the depth of the layer of workpiece material which is extruded below the cutting edge in oblique cutting, h , is equal to that ...

Effect of Ploughing Force on Cutting Forces in Micro-cutting with a Rounded-edge Cutting Tool

Materials Today: Proceedings, 2015
In micro- and nano-machining operations, the importance of cutting edge radius attracts attention to understand the mechanics of micro-cutting operations. In addition, the cutting edge radius causes higher ploughing forces and the ploughing force has many effects on the mechanics on micro- and nano-machining such as increasing the resultant force and ...

Shells of Revolution with Concentrated Edge Forces

Journal of the Engineering Mechanics Division, 1969
When a concentrated force is applied to a shell structure a stress results which may be regarded as being caused by the propagation of the effects of a localized disturbance into the shell. The way in which these effects distribute themselves is an interesting problem, especially for shells of negative Gaussian curvature, and it is investigated for ...

Extending edge modes with non-Hermitian forcing

Conference on Lasers and Electro-Optics, 2017
We show that introducing asymmetric coupling can force all the modes of a waveguide lattice to localize, except for one topologically protected “edge-state” which becomes extended. This mode has real eigenvalues and retains topological properties.

Edge forcing in tree-like architectures

Journal of Discrete Mathematical Sciences & Cryptography
To create independent edges in a graph G, this work presents a variant of the zero forcing set called the ‘edge-forcing set.’ A collection of vertices in G that can influence their neighbors to force all vertices to become forced iteratively is called a zero forcing set.

3n − 5 Edges Do Force a Subdivision of $K_{5}$

Combinatorica, 1998
It is shown that a graph on at least 3 vertices and with \(3n-5\) edges contains a subdivision of \(K_5\). This was conjectured by Dirac in 1964. The proof is fairly involved.

Finite amplitude effects in free and forced edge waves

Mathematical Proceedings of the Cambridge Philosophical Society, 1978
The effect of non-linearity on standing edge waves is studied on the basis of shallow water theory. Four problems are considered: the decay of free edge waves and the forcing of edge waves by an incident wave of double the frequency, a synchronous incident wave and by a side-wall wavemaker. Hysteresis effects are predicted for all types of forcing.
