Closed loop fiber optic rotation sensor [PDF]
, 1987 An improved optical gyroscope is provided, of the type that passes two light components in opposite directions through an optic fiber coil, and which adds a small variable frequency to one of the light components to cancel the phase shift due to rotation

Containerless protein crystal growth technology: Electrostatic multidrop positioner [PDF]
A brief discussion of containerless protein crystal growth in space and a diagram of the electrostatic multidrop positioner are presented. A picture of lysome crystals growing in a drop and a graph of levitation voltage versus time (minutes) are also ...

, 1999 An important theorem of Gross and Tucker characterises a directed graph $E$ which admits a free action of a group as a skew product. Here we extend this to directed graphs admitting free actions of semigroups, $S$, under certain hypotheses. Indeed, the main criterion we employ can be completely characterised by properties of the quotient map $E ...

A contribution to the theory of voltage graphs
Discrete Mathematics, 1986 This paper studies several problems in voltage graph theory (useful in constructing graph imbeddings), such as equivalence and regularity of coverings generated by (permutation) voltage graphs, and automorphism groups. To consider a sample result, let \(\chi\) be either an ordinary voltage assignment (OVA) or a permutation voltage assignment (PVA ...

HEURISTIC AND OPTIMUM SOLUTIONS IN ALLOCATION PROBLEMS [PDF]
In this paper we present some models and algoritms for solving some typical production planning and scheduling problems. We present the Resource-Constrained Project Scheduling Problem (RCPSP) and algorithms for the determination of maximal couplings with
