MAGNETIC TAPE CARE & RESTORATION

Wheeler, Jim 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / For the past thirty years, many people around the world have been engaged in studies to determine how long tape will last. We have learned how to extend the life of tapes but no one has come up with a method for predicting the life of a tape. This paper will summarize the present-day recommended practices for tape care and storage and will also describe the most common tape problems and how to overcome them. The most common problem with playing an old tape is finding a machine to play it. Machine obsolescence is probably a bigger problem than tape degradation.

Multiple Channel, Multiple Data Type, Rugged 8mm Recorder

Harris, Kevin E. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Low cost recording devices for telemetry and other data acquisition applications are of vital importance in light of today's shrinking budgets and project cut-backs. The desire to replace large, expensive, multi-channel recorders with smaller, less expensive recorders is becoming commonplace in government and industry. Many of these small recorders in the past have been limited to a single recording channel, and to one particular data type, due to recorder architectures. The 8 millimeter (8mm) tape cartridge recorder has been looked at in the past as a low cost recording device, however products utilizing this technology have been strictly limited in the number of channels, and data types. In response to this need, Veda has developed a new data acquisition recorder utilizing an 8mm recorder packaged in a small, flight qualified rugged enclosure with modular, and interchangeable, input channels. These microprocessor controlled inputs are capable of accepting PCM telemetry, MIL-STD-1553, voice, IRIG time, and ARINC 429/629 data. The new architecture allows for multiplexing of multiple channels onto the single channel tape medium as well as direct playback from the recorder for certain data types. This paper will discuss the recorder's architecture, design problems solved during development, and general capabilities.

Estudio de factibilidad de distribución de productos Tesa Tape en Lima

Gianella González, Fiorella, Oliva Guerra, Pilar, Turriate Solimano, Gino, Velasco Sepúlveda, Henry 02 January 2015 (has links)
El objetivo del presente “Estudio de Factibilidad”, fue demostrar la viabilidad de una distribuidora de cintas adhesivas especializadas industriales para el mercado de Lima en Perú. Por muchos años Perú ha sido un foco de progreso industrial, teniendo un PBI positivo durante los últimos 5 periodos, por encima del 5% y siendo reconocido a nivel mundial como una de las mejores economías emergentes de Latinoamérica. El mercado de cintas adhesivas tiene un potencial de más de 18 millones de dólares. Se destacan en el Perú solo tres empresas que atienden el mercado de cintas adhesivas con productos commodities, y solo una marca, de nombre 3M tiene productos especializados, con alrededor de 20 distribuidoras. De otro lado, una de las compañías más importantes en cintas adhesivas industriales de procedencia Alemana, identificó a un solo competidor directo dentro del mercado peruano y decidió incursionar en el. En ese sentido, en la actualidad la compañía Tesa Tape se encuentra en la búsqueda de un distribuidor que realice la labor de penetración y posicionamiento de sus cintas adhesivas, a través de su marca tesa, signo distintivo de gran reconocimiento internacional, siendo además líder en el mercado europeo. Las cintas adhesivas industriales, al ser productos de venta y aplicación especializada disponen de unos márgenes de ganancia que alcanzan entre un 30% a un 40%, asimismo como su concentración se da en el sector industrial no requieren de gran inversión en publicidad. Sin embargo, sí se hace necesaria la asesoría y acompañamiento técnico que será brindado por los asesores de la distribuidora, quienes deben estar muy bien capacitados, razón por la que la compañía tesa tape está dispuesta a invertir en su entrenamiento, ya sea que este se lleve a cabo en alguna de sus sedes del exterior, o de manera local. La distribuidora contaría con una estructura organizacional compuesta por 3 personas: una contadora-administradora, encargada de la administración y el control contable; dos representantes de ventas, quienes tendrían como objetivo cubrir geográficamente a la ciudad de Lima y un outsourcing de transporte. Asimismo se contará con una oficina comercial ubicada en una zona industrial y estratégica para la atención rápida y oportuna de los clientes. Con el plan financiero se desprende que con una inversión de capital de $ 300 mil dólares es viable realizar el proyecto simulado a un costo de capital del 13.4% el cual entrega un VAN de $ 77,725 dólares, una TIR de 19.3% y un Pay Back de 3.9 años.

3-D Analysis of a Functional Reach Test in Subjects With Functional Ankle Instability

de la Motte, Sarah J. 25 November 2008 (has links)
CONTEXT: 3-D kinematics and kinetics of the lower extremity during the Star Excursion Balance Test (SEBT) have not been examined in FAI subjects. Additionally, the effects of Kinesio® tape use in subjects with functional ankle instability (FAI) during functional tasks is uninvestigated. OBJECTIVE: To determine if lower extremity kinematics and kinetics differed in FAI subjects using Kinesio® tape during maximal SEBT reach. SUBJECTS: Twenty subjects with FAI (Age=24.2±3.8yrs; Ht=169±11.6cm; Wt=69±12.4kg) and twenty uninjured subjects (Age=25.7±5.6yrs; Ht=170.1.4±8.8cm; Wt=69.9±10.5kg) with no history of ankle sprain. FAI was operationally defined as repeated episodes of ankle “giving way” and/or ankle “rolling over”, regardless of neuromuscular deficits or pathologic laxity. All FAI subjects scored < 26 on the Cumberland Ankle Instability Tool. METHODS: SEBT reaches included the anteromedial, medial, and posteromedial directions. FAI subjects used their unstable side as the stance leg, while control subjects were side-matched to the FAI group. The stance leg ankle was taped using 1) Kinesio® tape and the Kinesio taping method (Kinesio method); 2) white linen tape with the Kinesio method; 3) Kinesio® tape along the distal peroneals tendons (lateral method); 4) white tape with the lateral method. Three-dimensional lower extremity kinematics, kinetics, and force plate data were collected during SEBT performance. A repeated measures ANOVA analyzed the effects of group, tape, tape method, and reach direction on all variables (α=0.05). Tukey HSD post-hoc analyses were performed for significant interactions. RESULTS: Normalized reach distance was not significantly different between groups in any direction (F2,76=1.16, P=.32). A significant four-way interaction for tape, method, direction, and group (F2,72=3.874, P=.03) was found. Post-hoc testing showed FAI subjects exhibited hip abduction while control subjects used hip adduction (Condition 1: .65±8.23° vs. -2.14±8.51°; Condition 2: 1.29±7.71° vs. -1.75±8.29°; Condition 3: 1.08±8.39° vs. -1.88±18.33°; Condition 4: 2.13±7.62° vs. -1.54±6.61°). Additionally, a significant difference in FAI subjects’ hip abduction angles between the white tape/Kinesio method (.65±8.23°) and Kinesio tape/Kinesio method (1.08±8.39°) was found. Conclusions: These results indicate that FAI subjects’ movement strategies differ from those of uninjured subjects. Furthermore, the use of Kinesio® tape at a distal joint can alter proximal joint movement in subjects with FAI.

Music for Solo Trumpet and Electronics: A Repertoire Study

Barth, Michael 05 January 2012 (has links)
This dissertation examines the repertoire for solo trumpet and electronics through a study of the genre as a whole and discussions of four compositions that represent its main stylistic approaches. An obscure but fascinating genre, current research in this area is limited to discussions of a few of its compositions in other dissertations and lecture recitals. By investigating this music, this dissertation will contribute to an area that has so far seen little research while promoting new repertoire that greatly expands the musical possibilities of solo trumpet performance. Based on the List of Compositions for Solo Trumpet and Electronics compiled by the author, several aspects of this repertoire are described in Chapter Two, including its development from 1965 to 2009 and the relative popularity of its different compositional approaches. The primarily academic background of this repertoire’s composers is discussed as well as the diverse nationalities they represent. The relative obscurity of this repertoire is suggested by the number of compositions for solo trumpet and electronics that have been published and recorded. A discussion of the aesthetic, qualitative and practical aspects of the repertoire is presented in Chapter Three. Based on interviews with leading performers of this repertoire and the composers of the pieces examined in this dissertation, this music is discussed from the perspective of musicians who have significant experience in this field. Their interviews illuminate several important issues that may not be apparent to musicians who are unfamiliar with this repertoire. Chapters Four through Seven discuss four representative compositions from the List. An overview of each piece is given, along with biographical information about its composer, a description of its electronic components, discussion of relevant performance techniques, and formal analysis of the composition. Conclusions based on this investigation and suggestions for future research are suggested in Chapter Eight.
