Context and Constraint in Presidential Unilateralism

SSRN Electronic Journal, 2011
How should we assess unilateral tactics and their contribution to presidential power in a less-than-unitary executive branch? To explore this question this paper examines the provenance of nearly 300 executive orders from 1947 through 1987. Archival data show that executive orders are frequently a less-than-perfect representation of presidential ...

Singularities in differential‐algebraic systems with unilateral constraints

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1998
AbstractInequality (unilateral) constraints may introduce various types of singularities in differential‐algebraic systems ([5]). In the present paper we consider contact conditions that are formulated as unilateral constraints for position and velocity coordinates in a mechanical multibody system.

Subdifferential Analysis and Plates Subjected to Unilateral Constraints

1989
The problems which lead to study differential properties of functionals which are not smooth, in a classical sense, form a very rich class and may concern very different fields of mathematics.

Systems Involving Unilateral Constraints

1991
A unilateral constraint is an idealized model of a structural component that limits some linear or angular distance to values either no greater than, or no less than, a certain magnitude. Unlike bilateral constraints, unilateral constraints are binding in only one sense of direction.

Complementarity Problems and Unilateral Constraints

1990
A simple formalism is proposed that leads to the unified treatment of many problems in Structural Mechanics. Such are the self-adjoint problems of statics of structures made of linear elastic, piecewise-linear elastic, elastic-plastic or rigid-plastic material.

Jourdain's principle for unilateral constrains

Acta Mechanica, 1986
The present paper deals with Jourdain's principle for unilateral constraints, depending on the velocities, written as a hemivariational inequality, so that it is possible to treat very general constraints. The difference from bilateral restrictions is discussed, and it is shown why it is not possible to describe rigid unilateral constraints with the ...

Cooperative manipulation with unilateral constraints

2011
Cooperative manipulation provides multiple robots the capability to perform tasks that are difficult or even impossible to be executed by a single manipulator. Among these tasks are, for instance, carrying heavy or large payloads, conducting multi-part assembly, and handling of flexible objects. If a large object with no special features (e.g.
