|
 | To achieve the goal of the proposal, we created nano-structured surfaces to increase the pixel density and hence resolution of the opto-electronic sensor array by a factor of 3 in each direction, x and y. The proof of concept of this mathematical framework in the visible part of the optical spectrum was published in 2 journal articles (both published in Applied Physics Letters). In addition to this, we also experimentally ... |

H. T. Hahn; R. Pandey; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
 | A micromechanics model is presented to predict thermoelastic properties of composites reinforced with plain weave fabrics. A representative volume element is chosen for analysis and the fiber architecture is described by a few simple functions. Equations are developed to calculate various phase fractions from geometric parameters that can be measured on a cross section. Effective elastic moduli and effective thermal expansion coefficients are determined under the assumption of uniform strain ... |

| NUMERICAL SOLUTION OF DYNAMICAL OPTIMIZATION PROBLEMS, |
JUL 1969 |
|
| Authors:
S. De Julio; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| The paper is a study of the technique proposed by Balakrishnan as applied to infinite dimensional linear systems. This technique is different from other methods and seems to have two major advantages over them. First of all, it is more general in that it applies to a broad class of systems which contains the previous ones as particular cases. The second advantage, but not the least, is that the computational ... |

| Authors:
A. V. Balakrishnan; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| In applying optimal control ideas to practical systems and particularly as such applications embrace an ever-increasing class of systems, it is often the case that the kind of description demanded by that theory is not available or is incomplete, and must be deduced from external measurements. The general problem that this leads to is the 'identification' of a system from input-output measurements and is important in areas outside engineering such ... |

A. V. Balakrishnan; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| In this paper we present the first results in applying a new computing technique for optimal control problems to a minimal time flight trajectory optimization problem. We also indicate how the technique may be extended to the isoperimetric problem of Lagrange with equality constraints. In particular, the method yields a constructive way of obtaining the Lagrange multipliers whose existence alone is usually proved. We actually obtain an approximate maximum principle ... |

Rahul Chattopadhyay; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| A new method is developed for the solution of linear pursuit-evasion problems. A pursuit-evasion problem, which will be defined precisely in a later section, mainly consists of a two dynamical systems usually denoted by P and E. It is assumed that P is trying to 'intercept' E against opposition from E, where 'interception' is defined in some precise way. The theory of minimum-normed linear functionals is used in this article ... |

Chin Tung; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| The continuing reduction of the size and cost of microelectronic logic elements encourages the utilization of more complex logic nets in digital computers. In arithmetic processors, because of the application of these complex logic nets, the replacement of sequential logic nets by their combinational equivalents and the substitution of programmed software subroutines by hardware function generators are to be economically justified in the near future. The kernel of this combinational ... |

Douglas N. Bennion; Neng Ping Yao; Emmanuel D'Orsay; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| Two potentially useful high energy battery electrolyte solvents, tetramethylene sulfoxide (TMSO) and dimethyl sulfite were characterized. Charging and discharging tests have shown that lithium metal can be deposited and discharged from lithium perchlorate solutions in these solvents with 50 to 90 percent charge efficiency. The discrepancy from 100 percent is apparently due to water contamination. Potasium persulfate, copper fluoride, iodine, and silver chloride all yielded promising behavior as battery positives ... |

George Sines; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| In an attempt to discover the mechanism by which the transport of atoms occurs under extreme microscopic stress gradients, alloy filamentary crystals were grown from the solid plating subjected to lateral compression. Enrichment of one species in the filamentary crystal would be expected if diffusion were the controlling mechanism. X-ray lattice diffraction measurement of the atomic spacing of Pb-In and Sn-In alloys appears promising. Also electron microprobe appears promising if ... |

Russell L. Smith; John Lyman; CALIFORNIA UNIV LOS ANGELES DEPT OF ENGINEERING
|
| The experiment assessed the extent to which operators employed predictive behavior on two-dimensional tracking. Two problems were presented: in one, operators were asked to extrapolate an overlearned trajectory upon the disappearance of the target and in the other, operators tracked one of four possible trajectories with and without pre-test knowledge concerning the specific trajectory that would be presented. No evidence was found which suggested that operators exhibited predictive behavior on ... |

| The (approximate) solution of optimal control problems involving partial differential equations is studied by discretizing the space domain and considering the resultant set of ordinary differential equations. This approach is certainly not new. However, earlier efforts along this path have been hampered by the difficulties involved in solving the optimal control problem for the very large sets of interacting ordinary differential equations which arise as the discretization interval is decreased. ... |
