Standard work is commonly used in manufacturing and assembly operations to minimize process variation by providing detailed instruction to operators. Internal best practices are processes within the firm that achieve a more beneficial result when compared to alternative existing methods. Standard work is one approach to share best practices, and the challenge is in identifying their existence and effectively capturing the information in written documentation. Best practices are often tacit in nature, being difficult to codify and to put into writing. Effectively finding internal best practices and transferring them from tacit to explicit form as standard work is a desirable objective, improving knowledge transfer and operational efficiency within the company. There are techniques that can be applied to the standard work development process that increase the likelihood of successful best practice capture and organizational adoption. These techniques are developed and implemented through application at Sikorsky Aircraft, in creating and deploying a system of standard work titled, the "Assembly and Flight Operations Franchise Book." Major process steps in developing and sustaining standard work include an initial planning phase characterized by an upfront analysis, organizational structuring, and content framework development; and a sustaining phase characterized by a repeating cycle of best practice discovery, documentation, and sharing.

Giannitsis, Constantine 1971. "Non-linear saturation of vertically propagating Rossby waves." Thesis, Massachusetts Institute of Technology, 2001. http://hdl.handle.net/1721.1/53043.
Повний текст джерелаIncludes bibliographical references (p. 203-208).
Linear quasi-geostrophic theory predicts an exponential amplitude increase with height for Rossby waves propagating vertically through a stratified atmosphere, as a result of wave activity density conservation. At the same time layer-wise conservation of potential enstrophy constrains wave amplitudes, given the limited amount of potential enstrophy available in the initial mean flow. A break down of linear theory is thus expected above a certain critical wave amplitude, raising the question of how the non-linear flow reacts to limit the vertical penetration of waves. Keeping in mind the potential importance for the dynamics of the winter stratosphere, where strong wave penetration and amplitude growth are often observed, the issue of wave saturation in a non-linear flow is examined in a generally abstract context, through a variety of simple model studies. We thus consider the cases of a topographically forced barotropic beta plane channel model, of vertical propagation through a three-dimensional beta plane channel model, and of a polar coordinate model with realistic basic state and geometry. In the barotropic model transient wave growth is forced through the use of bottom topography and the deviations of the non-linear flow evolution from the predictions of both a linear and a quasi-linear analytical solution are examined for strong topographic anomalies. The growth of the forced wave is found to decelerate the zonal mean flow which in turn reduces the topographic forcing. Wave-mean flow interactions are thus found to be sufficient in leading to saturation of the eddy amplitudes. Interestingly it is the formation of zonal mean easterlies, rather than the depletion of mean available potential enstrophy, that is found to be the crucial factor in the saturation dynamics. Similar results are obtained for the case of vertical propagation through a three dimensional beta plane channel. The vertical penetration of the forced wave is shown to cause a reduction of the zonal mean winds and mean potential vorticity gradients in the center of the channel, eventually leading to the formation of either a critical line or a refractive index turning surface. In both cases the penetration of the wave to high altitudes is prohibited, thus constraining wave amplitudes. While signs of non-linear behaviour are clear in synoptic maps of potential vorticity, wave-wave interactions are found to play a secondary role in the saturation process. The results of the three-dimensional beta plane channel model are then extended to a more realistic set-up, using a polar coordinate model with a basic state based on the observed winter stratosphere climatology. The basic conclusions of the idealized study are shown to remain unchanged.

Повний текст джерелаDie Wechselwirkung von elektromagnetischer Strahlung mit subwellenlängenkleinen Teilchen bzw. Oberflächenstrukturen ermöglicht nicht nur eine Miniaturisierung optischer Geräte, sondern erlaubt sehr interessante Anwendungen, beispielsweise in der Sensorik und Nahfeldoptik. In der vorliegenden Arbeit werden die zu Grunde liegenden Effekte im Rahmen der klassischen Elektrodynamik mit Hilfe der semianalytischen Methode der multiplen Multipole (MMP) analysiert, und die Ergebnisse werden mit Experimenten verglichen. Im ersten Teil werden Oberflächenplasmonenresonanzen (engl. surface plasmon resonance - SPR) einzelner und wechselwirkender Metallteilchen untersucht. Die dabei auftretende resonante kollektive Schwingung der freien Elektronen des Partikels bewirkt eine deutliche Erhöhung und Lokalisierung des elektromagnetischen Feldes in seiner Umgebung. Die spektrale Position und die Stärke der SPR eines Nanoteilchens, die von dessen geometrischer Form, Permittivität und Umgebung abhängen, können nur im Grenzfall sehr kleiner Teilchen elektrostatisch beschrieben werden, wohingegen der verwendete semianalytische MMP-Ansatz weitaus flexibler ist und insbesondere auch auf größere Partikel, Teilchen mit komplizierterer Form bzw. Ensembles von Partikeln anwendbar ist. Die betrachteten einzelnen kleinen (< Wellenlänge) Goldkügelchen und Silberellipsoide besitzen eine stark ausgeprägte SPR im sichtbaren optischen Bereich. Diese ist auf eine dipolartige Polarisierung des Teilchens zurückzuführen. Höhere Moden der Polarisation können entweder als Folge von Retardierungseffekten an größeren (mit der Wellenlänge vergleichbaren) Teilchen oder bei der Verwendung inhomogener (z.B. evaneszenter) Wellen angeregt werden. Partikel, die sich in der Nähe eines Substrates befinden, unterliegen der Nahfeldwechselwirkung zwischen den (lichtinduzierten) Oberflächenladungen auf der Oberfläche des Teilchens und des Substrats. Dies führt zu einer Verschiebung der SPR zu niedrigeren Frequenzen und einer Erhöhung des lokalen elektrischen Feldes. Letzteres bildet die Grundlage z.B. der spitzenverstärkten Raman-Spektroskopie und der optischen Nahfeldmikroskopie mit Streulichtdetektion. Dasselbe Prinzip bewirkt ein stark überhöhtes elektrisches Feld zwischen miteinander wechselwirkenden Nanopartikeln, welches z.B. die Sensitivität der oberflächenverstärkten Raman-Mikroskopie um mehrere Größenordnungen steigern kann. Im Gegensatz zur SPR einzelner Nanopartikel kann die Resonanz der Lichtstreuung im Fall eines Partikels in der Nähe eines Substrats aus der durch die Nahfeldwechselwirkung induzierten Anregung elektromagnetischer Oberflächenzustände entstehen. Diese wirken ihrerseits auf das Nanopartikel zurück, wobei eine resonante Lichtstreuung beobachtbar ist. Dieser, am Beispiel einer metallischen Nahfeldsonde über einem Siliziumcarbid-Substrat analysierte, Effekt ermöglicht bei einer ganzen Klasse von polaren Kristallen interessante Anwendungen in der Mikroskopie und Sensorik basierend auf der hohen Dichte von Oberflächenphononpolaritonen dieser Kristalle im mittleren infraroten Spektralbereich und deren nahfeldinduzierten Anregung. Im zweiten Teil der Arbeit werden kollektive Anregungen von Elektronen an Metalloberflächen untersucht. Die dabei auftretenden plasmonischen Oberflächenwellen (engl. surface plasmon polaritons - SPPs) weisen einen exponentiellen Abfall der Intensität senkrecht zur Grenzfläche auf. Diese starke Lokalisierung der Energie an der Oberfläche bildet die Grundlage vieler Anwendungen, z.B. im Bereich der hochempfindlichen Detektion (bio)chemischer Verbindungen oder für eine zweidimensionale Optik (engl. plasmonics). Das Aufheben der Translationsinvarianz längs der Oberfläche ermöglicht die direkte Anregung von SPPs durch ebene Wellen. Die Abhängigkeit dieser Kopplung von der Geometrie wird am Beispiel eines Nanograbens untersucht. Dabei werden neben den SPPs ebenfalls eine oder mehrere Moden im Graben angeregt. Folglich ermöglicht die geeignete Wahl der Grabengeometrie die Optimierung der Umwandlung von ebenen Wellen in SPPs. Im - in der Praxis weit verbreiteten - Fall asymmetrisch eingebetteter metallischer Dünnschichtwellenleiter existieren zwei Moden. In Abhängigkeit von der Grabenbreite kann die eine oder die andere Mode bevorzugt angeregt werden. Die Analyse der Wechselwirkung von SPPs mit Oberflächenstrukturen, z.B. Kanten, Stufen, Barrieren und Gräben, zeigt die Möglichkeit der Steuerung der Reflexions-, Transmissions- und Abstrahleigenschaften durch die gezielte Wahl der Geometrie der "Oberflächendefekte" auf der Nanoskala und deckt die zu Grunde liegenden Mechanismen und die daraus resultierenden Anforderungen bei der Herstellung neuer plasmonischer Komponenten auf. Exemplarisch wird das Prinzip der SPP-Anregung an einzelnen und mehreren Gräben in dünnen metallischen Filmen sowie der subwellenlängen Feldlokalisierung an sich verjüngenden metallischen Dünnschichtwellenleitern unter Verwendung der optischen Nahfeldmikroskopie experimentell gezeigt

Повний текст джерелаAn experiment was conducted which measured the Radio Frequency (RF) radiation from the PHERMEX accelerator, capable of 30 MeV and 600 A. This was accomplished by placing TEM horn antennae at varying angles from the path of the electron beam. The signals received by the antennae were then recorded by using a Digitizing Camera System (DCS). Measurements were taken of the radiation from propagating and non-propagating beams, beams with energy above and below Cherenkov threshold, and beams with varied currents. The captured RF signals and their corresponding frequency spectra were then analyzed. This analysis showed that the radio frequency radiation from the beams below the cherenkov threshold contained primarily transition radiation; when above, diffracted Cherenkov radiation was observed. Non-propagating beams produced larger-angle radiation and had less definition in their spectrum. All electric fields measured were proportional to the beam current. Lastly, the electron beam pulse width and separation were determined by both the received signals and their spectrum.

Повний текст джерелаThe prompt and accurate processing of sonar data is essential in undersea warfare. The ability to quickly detect and classify sonar targets is crucial to the performance and survivability of all navy surface ships and submarines. With the advent of neural network technology, new opportunities have arisen which could greatly enhance current sonar target recognition capabilities. The main objective of this research is to demonstrate the practical usage of neural networks in recognizing the acoustic signatures of passive sonar targets using simulated-at-sea conditions. We will review the theory behind neural networks, the problems associated with recognizing acoustic signals in an underwater environment, and we will make a detailed case study of a neural network's performance using test data generated from simulated sonar targets.
