An Investigation of the Effects of Relative Winds Over the Deck on the MH-60S Helicopter During Shipboard Launch and Recovery Operations
No full textVertical replenishment (VERTREP) of underway fleet naval vessels by helicopter is the primary mission of the MH-60S helicopter and is absolutely critical to sustaining fleet combat readiness at sea. The effectiveness of the MH-60S helicopter in conducting this crucial mission is directly dependent upon its ability to launch from and recover to the delivery ship under a wide range of wind-over-deck (WOD) conditions.
This thesis is an investigation of the effects of relative winds over the deck on the MH-60S helicopter documented during shipboard launch and recovery operations conducted during the initial MH-60S shipboard testing and launch and recovery wind envelope development.
The investigation involved the calculated variation of relative wind-over-deck speed and direction during shipboard launch and recovery evolutions. Effects of the relative winds over the deck on the helicopter during launch and recovery were quantified using pilot rating scales, designed to permit the brief yet accurate characterization of aircraft handling qualities and pilot workload. Build-up flight test techniques were used to mitigate the risk associated with shipboard launch and recovery wind envelope development.
This investigation yielded a satisfactory characterization of the handling qualities of the MH-60S helicopter aboard three different classes of naval vessels. Additionally, it resulted in the establishment of relatively large and operationally flexible launch and recovery wind envelopes for each of these classes of ship, all of which are recommended for employment by the fleet upon introduction of the helicopter.
The investigation also yielded four unsatisfactory pilot-vehicle interface (PVI) deficiencies pertinent to operating the MH-60S helicopter aboard ship. They were related to extremely limited forward field of view (FOV), excessive cockpit vibrations, aft location of the tail wheel, and hazardous strength of the main rotor down wash.
It is the opinion of this author that much can be done to make the immense task of initially qualifying a new helicopter for operations aboard all classes of naval ship safer, and more economical, efficient and logical. It is also the position of this author that this initial MH-60S shipboard test effort did not satisfactorily leverage the massive amount of knowledge pertinent to such an endeavor that currently exists in government, military, civilian and academic institutions of the world interested in this field of study.
If U. S. Navy launch and recovery wind envelope development is to succeed at truly maximizing the shipboard operational capability of a helicopter, more must be done to leverage the tremendous technological advances being made in this and related fields of study, and to employ data already gathered by institutions conducting similar testing
Children „write down” martial law, adults „rework” traumas. Martial law memory in light of Dominick LaCapra’s theory
No full textArtykuł stanowi próbę zrozumienia traumy stanu wojennego. Przy pomocy aparatu pojęciowego wypracowanego przez Dominicka LaCaprę analizie poddane zostały dwa utwory współczesnej literatury polskiej – Wilczek K. Ryrych oraz Wroniec J. Dukaja. Chociaż myśl amerykańskiego badacza skupia się przede wszystkim wokół treści traumatycznych powiązanych z II wojną światową i Zagładą, to jednak jego teoria przystaje także do innych trudnych wydarzeń historycznych. Autorka artykułu stara się zrewidować sposób, w jaki pamięć o stanie wojennym została zoperacjonalizowana przez pisarkę i pisarza, a także spojrzeć na ich teksty poprzez pryzmat osobistej strategii oswajania traumy. Analizowane utwory pokazują, iż stan wojenny nie jest „doświadczeniem niczyim”, a więc właściwie obecnym-nieobecnym, dotykającym każdego i nikogo, przeciwnie – to ważny problem społeczeństwa polskiego, który wymaga jednak przenicowania oraz nowego, być może także kreatywnego spojrzenia.The article is an attempt to understand the trauma of martial law. Using the conceptual apparatus developed by Dominick LaCapra, two works of contemporary Polish literature – Wilczek by K. Ryrych and Wroniec by J. Dukaj – are analyzed. Although the thought of the American researcher focuses primarily on the traumatic content associated with World War II and the Holocaust, his theory also befits other difficult historical events. The author of the article seeks to revise the way in which the memory of martial law has been operationalized by the writers, and to look at their texts through the prism of their personal strategies for taming the trauma. The analyzed works show that martial law is not a „nobody’s experience”, that is, it is actually present-absent, affecting everyone and no one; on the contrary, it is an important problem of Polish society, but one that needs to be reframed and looked at in a new, perhaps also creative way

Synthesis and Photophysical Studies of Novel Water-Soluble Cu(I) Phenanthroline Mixed-Ligand Complexes Containing 1,3,5-Triaza-7-phosphaadamantane
No full textThe new luminescent 1-D polymeric compound [Cu(dmp)(µ-PTA)]n(NO3)n•nH2O (complex 1) (dmp = 2,9-dimethyl-1,10 phenanthroline and PTA = 1,3,5 - triaza - 7 - phosphaadamantae_) containing coordination from both phosphorous and nitrogen atoms on the phosphaadamantane and the mononuclear Cu(dmp)(PTA)2NO3 (complex 2) (phosphorus coordination only from the PTA) were prepared by reacting the Cu(I)(dmp)2 with two equivalents of PTA in a homogenous solution at room temperature. Both compounds are water-soluble and air-stable, and were characterized by single crystal X-ray diffraction, 1H and 31P NMR. Complex 1 and 2 exhibit distinct photoluminescence in the solid state, DCM solution, and frozen glass, thus providing the potential for the production of water-soluble PTA-based photovoltaic devices.Embargo status: Restricted to TTU community only.

Design and synthesis of novel [1]rotaxane monomers for the preparation of slip-link polymers
No full textIncorporation of mechanical bonds into a polymer backbone has the potential to impart unusual properties on a polymeric material. For instance, low activation energy for viscous flow, and rapid stress relaxation have all been predicted for these structures. Slip-link polymers, a novel class of mechanically-interlocked polymers, are expected to show unique responsiveness under external stimuli. However, synthetic routes to such polymeric architectures remain either rare or unsuccessful. This dissertation presents a novel synthetic strategy toward slip-link polymers. In our new approach to access slip-link polymers, initially, a self-entangled [1]rotaxane is designed and synthesized for use in entropy-driven ring-opening olefin metathesis polymerization (ED-ROMP). Upon careful adjustment of this olefin metathesis reaction, a self-entangled [1]rotaxane was polymerized with Grubbs II catalyst to produce slip-link polymers. Motivated by the initial results of the polymerization of [1]rotaxanes, a series of [1]rotaxanes with a variety of structures were designed and synthesized in our laboratory to extend the scope of synthesis for slip-link polymers. This dissertation will focus on our efforts toward the design of the components of the [1]rotaxane, [1]rotaxane synthesis, and polymerization results.Embargo status: Restricted to TTU community only.

Autobiography as unconventional history: Constructing the author
No full textThe experience of historians as autobiographers has led them to reconsider the nature of historical knowledge and the function of the historian as an intermediary between the past and present. In the new theoretical context of the social sciences and historiography, we can take this proposal further and consider autobiography as a valid form of history—or, at least, as ‘unconventional history’, understood as negotiations with history that transcend or subvert traditional chronological monographs, posit the ‘subjective’ as a useful form of knowledge, and engage the constructed nature of the text. Taking this hypothesis as a starting point, this article reads historians' autobiographical texts to explore if we can/should continue to defend the classic distinction between subject and object, historian scientist and historian author. In this article I compare the work of several historian autobiographers that permit us to identify different methodologies in approaching the story of the self that also reflects different theoretical conceptions of history. I argue that historians that may be considered ‘constructionist’, such as Fernand Braudel, Annie Kriegel, George Duby, and Eric Hobsbawm, design their autobiographies in the same way they articulate their historical texts: by foregrounding objectivity and establishing critical distance between the subject—the historian who narrates the story—and the object—one's own life. Unconventional or experimental approaches, such as those espoused by Robert Rosenstone, Dominick LaCapra, or Clifford Geertz, result in more self-conscious autobiographies, which are, paradoxically, often more realistic and more revealing of the epistemological nature of life writing. ----------------- La experiencia de los historiadores como autobiógrafos les ha llevado a reconsiderar la naturaleza del conocimiento histórico y la función del historiador como un intermediario entre el pasado y el presente. En el nuevo contexto teórico de las ciencias sociales y la historiografía podemos tomar esta propuesta más allá y considerar la autobiografía como una forma válida de historia-o, al menos, de historia ‘poco convencional’-, entendida como negociaciones con la historia que trascienden o subvierten las tradicionales monografías cronológicas, plantean lo "subjetivo" como una forma útil de conocimiento y participan de la naturaleza construida del texto. Tomando esta hipótesis como punto de partida, este artículo lee los textos autobiográficos de los historiadores para explorar si se puede / debe seguir defendiendo la clásica distinción entre sujeto y objeto, historiador científico e historiador escritor. En este artículo comparo el trabajo de varios historiadores autobiógrafos que nos permiten identificar las diferentes metodologías para acercarse a la historia del yo y que también reflejan las diferentes concepciones teóricas de la historia. Sostengo que los historiadores que pueden considerarse "constructivistas", como Fernand Braudel, Annie Kriegel, George Duby y Eric Hobsbawm, diseñan sus autobiografías de la misma forma que articulan sus textos históricos: poniendo en primer plano la objetividad y estableciendo una distancia crítica entre el sujeto -el historiador que narra la historia-y el objeto- la vida de cada uno. Enfoques no convencionales o experimentales, como los expuestos por Robert Rosenstone, Dominick LaCapra, o Clifford Geertz, resultan autobiografías más autoconscientes, que son, paradójicamente, a menudo más realistas y más reveladoras de la naturaleza epistemológica de la escritura de la vida
