This paper presents the impacts of an innovative project in the coffee business, carried out in Nicaragua. ECOM, a major coffee exporter, had invested in a coffee renovation project with hybrid plants but faced the challenge of selling these plants to local coffee farmers. A student consulting team was assigned to the project, which helped ECOM to develop an innovative sales structure to increa...
David Chalmers's version of two-dimensional semantics is an attempt at setting up a unified semantic framework that would vindicate both the Fregean and the Kripkean semantic intuitions. I claim that there are three acceptable ways of carrying out such a project, and that Chalmers's theory does not coherently fit any of the three patterns. I suggest that the theory may be seen as pointing to th...
A discussion is presented on design problems encountered in the Beam Switchyard area of the two-mile electron accelerator 'due to the requirement of a maximum average beam power of 2 megawatts. A description is given of the various aspects of beam interception. The paper describes the general solution to these problems, _-particularly with respect to the construction of beam monitors rs and bea...

We generalize the classical Legendre-Hadamard conditions by using quadratic extensions of the energy around a set of two configurations and obtain new algebraic necessary conditions for nonsmooth strong local minimizers. The implied bounds of stability are easily accessible as we illustrate on a nontrivial example where quasiconvexification is unknown.
In this paper we determine, in dimension three, the effective conductivities of non periodic high-contrast two-phase cylindrical composites, placed in a constant magnetic field, without any assumption on the geometry of their cross sections. Our method, in the spirit of the H-convergence of Murat-Tartar, is based on a compactness result and the cylindrical nature of the microstructure. The homo...
It is shown that balanced n-bit Gray codes can be constructed for all positive integers n. A balanced Gray code is one in which the bit changes are distributed as equally as possible among the bit positions. The strategy used is to prove the existence of a certain subsequence which will allow successful use of the construction proposed by Robinson and Cohn in 1981. Although Wagner and West prov...
