|
| Typical OLEDs are constructed in a bottom-emitting configuration where active organic layers are deposited on top of a transparent electrode, such as indium-tin-oxide (ITO), and then a non-transparent low function metal cathode, such as Mg, Ca, Li, is deposited as the top electrode. When appropriate current and voltage are applied to the electrodes, the organic layers are activated, and light is produced which can be seen at the transparent ITO ... |

|
| In an effort to combat windscreen erosion on Army aircraft, a Mylar film has been developed to apply directly to the environmentally exposed surface of windscreens. This film can be applied to aircraft windscreens in single or multiple layer sheets, which once removed will leave no permanent residue on the underlying surface. A qualitative evaluation of Mylar Tear-Off Windshield Film (MTOWF) has been conducted, and indicates that MTOWF is appropriate ... |

| Our aim is to find the symmetry reductions related to the PDE (8) hidden by the nonlinearity that occurs between the data and the parameter -> group of transformations that leave the equation unchanged, which also relate the inverse and the direct problem -> knowledge of the invariants of these group actions allows us to write the target shape and the parameter in terms of them, and therefore, to reduce ... |

 | Temporal waveforms of the illumination at the driver eyes position were determined in various night traffic and weather conditions (ideal weather and correct aligned lights as compared with dirty lamps and raindrops on the windscreen). The statistics of retinal illumination were analyzed and a computer controlled technique was developed to simulate similar changes of eye illumination. The participant fixated on retroreflective optical stimuli at a distance of 5 m. The ... |

|
| When an observer looks through an aerospace transparency, relative optical distortion may result, specifically in thick, highly angled, multi- layered plastic parts. Distortion occurs in all transparencies but is especially critical to aerospace applications such as combat and commercial aircraft windscreens, canopies and cabin windows. This is especially true during certain operations such as takeoff, landing and aerial refueling. It is critical to be able to quantify optical distortion for ... |

|
| Modern fighter aircraft windscreens and canopies are typically made of curved, transparent plastic for improved aero-dynamics and bird-strike protection. Since they are curved these transparencies often refract light in such a way that a pilot looking through the transparency will see a target in a location other than where it really is. This effect has been known for many years and methods to correct the aircraft head-up display (HUD) for ... |

Peter L. Marasco; H. L. Task; AIR FORCE RESEARCH LAB WRIGHT-PATTERSON AFB OH HUMAN EFFECTIVENESS DIRECTORATE
|
| The amount of scattered light, or haze, typically increases as transparent materials age, wear, become dirty, or become scratched from cleaning. Light scattered from scratched aircraft transparencies, such as windscreens, head-up-display combiners, and helmet visors, can potentially reduce pilot visual performance and reduce target detection range. Presented in this paper are the results of an investigation of light scattered from transparencies exhibiting different levels of wear and surface damage. Two ... |

| Productivity measurement is a required management tool in evaluating and monitoring the performance of a business operation. Productivity is, therefore, a major concern in today's business organizations that enable it to survive and be profitable. To become a more meaningful management tool, productivity measurement methodologies must show the linkage with profitability for which management is held accountable.

| Machining instability, namely chatter, occurs due to the interaction between the structural dynamics and the cutting process. The process damping generated at the tool-workpiece interface is an important parameter of that interaction. A significant enhancement to the chatter simulation model in milling is presented. It includes tracking of the interference between the tool flank and the generated wavy surface, which is the source of process damping. Results of simulation runs ... |

| The flat panel display (FPD) market is growing, even more rapidly than display makers had expected. Active matrix liquid crystal displays (AMLCDs), the currently dominant technology, have inherent limitations that may render them unsuitable for some future applications. Moreover, Japanese companies have a huge lead in AMLCD development. Field emission displays (FEDs) overcome some of these limitations and may help US firms enter the FPD arena, but are still an ... |

| Sputtering targets used in the manufacture of advanced semiconductor devices must meet increasingly stringent performance standards. For example, the film uniformity specification for 200-mm wafers metallized with the Applied Materials Endura 5500 sputtering system is that thickness variation must be less than 1.67 percent (1o with 6-mm edge exclusion). This requirement means that for a 1-um thick aluminum film, thickness can vary by only plus or minus 58 atoms. To ... |

Though solid modelers have been able to show simple assemblies consisting of a few dozen parts, they have been unable to handle anything more complex. The reason: parametric features, increasingly in demand by designers, make for a huge information overhead. An assembly of ... |

| Closed-loop control of hydraulic actuators continues to grow in importance as the motion-control market demands higher accuracy and speed, along with the ability to change operations on the fly. Perfomance of electronically controlled fluid-power systems can match--or exceed--that of electromechanical actuators in many cases. One advantage of electronic control is it allows faster actuator cycling while eliminating shock and impact loads. The systems are also well-suited to meet flexible-production requirements, ... |

| In FEA, designers pick an equation or function that defines the primary unknown, deflection for stress or temperature, for example, as a function of x, y, and z space. If we knew this equation exactly, we could rule the engineering world. Unfortunately, exact solutions are nearly impossible to find, so the solutions are approximated by selecting a polynomial function. The key question is how many terms (the degree or p ... |

In particular, high compressive stress in silicon nitride over aluminum alloy metallization was reported to greatly enhance the incidence of voiding (1). While the exact reason is unclear, it is good practice to avoid high compressive stresses in silicon nitride films. ... |
