Electric analog for measuring induced drag on nonplanar airfoil

Process for control of cell division

A method of controlling mitosis of biological cells was developed, which involved inducing a change in the intracellular ionic hierarchy accompanying the cellular electrical transmembrane potential difference (Esubm) of the cells. The ionic hierarchy may be varied by imposing changes on the relative concentrations of Na(+), K(+) and Cl(-), or by directly imposing changes in the physical Esubm level across the cell surface

Improving Maintenance Data Collection via Point-of-Maintenance (POMX) Implementation

Maintenance data collection is an integral part of flightline aircraft maintenance. Historically, this data was input via traditional keyboard data entry methods at a computer terminal. These terminals are typically located in the aircraft maintenance unit (AMU) facility, away from where the actual maintenance is being performed. In contrast to the traditional approach, the Point-of-Maintenance system (POMX) seeks to reduce the data entry burden while increasing data accuracy through the use of E-Tools such as ruggedized laptop computers and handheld portable maintenance aids (PMAs). POMX enables data entry at the aircraft or other maintenance location via wireless local area network or batch storage, and seeks to capture data as the maintenance is performed. This research analyzes the impact of a POMX system on maintenance data error rates. This research takes a careful look at the implementation of POMX at Randolph AFB to enable current designers and system engineers to gain insight into what to expect as the next generation of POMX comes on-line. Initial results indicate no significant improvement in data quality and no reduction in the number of data errors recorded with POMX systems. Follow-up interviews with POMX users and experts revealed that the Air Force still has a number of managerial, technical and organizational constraints which must be overcome before a POMX system can add to the effectiveness of Air Force maintenance operations

A Mathematical Analysis of the Dynamic Soaring Flight of the Albatross with Ecological Interpretations

The capability of flight plays a central role in the lives of most birds. Indeed, the existing morphological and ecological characteristics of many species are almost entirely dictated by the aerodynamic requirements of the highly developed flight modes they have acquired through evolutional specialization. In the case of such species, a clear understanding of the aerodynamic mechanisms underlying the particular flight modes can often provide a lucid insight into the basic physical relationships which govern a bird\u27s characteristic activities and behavior. This aerodynamic approach to the study of avian ecology is particularly useful in the case of soaring birds, where survival depends entirely upon the aerodynamic efficiency of the bird in exploiting the energy of special forms of air currents for sustained flight, and where the wing actions are sufficiently simple that the flight patterns can adequately be formulated for aerodynamic analysis. Such an approach was utilized by the author in a recent study of land birds which practice soaring flight in thermal air currents. By applying aerodynamic precepts to the analysis and interpretation of observed flight patterns, it was possible to explain, correlate, and even predict many facts of importance in the morphology and ecology of the land soarers. It is the purpose of the present study to apply a similar analysis to the dynamic soaring flight of sea birds, such as the albatross, and to utilize the results for establishing the significant factors in the ecology of the ocean soarers

Optimized Confinement of Fermions in Two Dimensions

One of the challenging features of studying model Hamiltonians with cold atoms in optical lattices is the presence of spatial inhomogeneities induced by the confining potential, which results in the coexistence of different phases. This paper presents Quantum Monte Carlo results comparing meth- ods for confining fermions in two dimensions, including conventional diagonal confinement (DC), a recently proposed 'off-diagonal confinement' (ODC), as well as a trap which produces uniform den- sity in the lattice. At constant entropy and for currently accessible temperatures, we show that the current DC method results in the strongest magnetic signature, primarily because of its judicious use of entropy sinks at the lattice edge. For d-wave pairing, we show that a constant density trap has the more robust signal and that ODC can implement a constant density profile. This feature is important to any prospective search for superconductivity in optical lattices

The Early to Middle Ordovician graptolite faunal succession of the Trail Creek region, central Idaho, U.S.A

The Middle Ordovician graptolite biostratigraphy of the Trail Creek region of Idaho is reviewed and revised. The oldest known fauna belongs to the Didymograptellus bifidus Biozone. The Isograptus victoriae lunatus, I. victoriae maximodivergens, Oncograptus, Undulograptus austrodentatus and Holmograptus lentus Biozones can be differentiated. Pseudophyllograptus archaios (Braithwaite) is found for the first time in the Trail Creek region. This species represents a conspicuous North American mid-continent faunal element and enables the correlation of the endemic P. archaios-C. flexilis Biozone of Utah with the D. bifidus Biozone of the Pacific faunal realm, thus, providing an important tool for the correlation of endemic mid-continent faunas with the pandemic deep water graptolite faunas
