The design and implementation of an elite training system for tennisDallis, Robert January 2002 (has links)
Thesis (Ed.D.)--Boston University / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / The purpose of this study was to design a framework for a tennis training system that can be used to develop young tennis players into elite, world-class professionals. An elite tennis player is defined as someone who ultimately attains a top 200 professional ranking on either the men's ATP Tour or the women's WTA Tour. This system is meant to be utilized by training institutions as a whole, as well as individual players and their coaches. The methodology involved a literature review of research in youth talent development and talent detection, with emphasis on the works of Bloom (1985) and Ericsson (1990, 1993, 1994, 1996). Interviews were also conducted with prominent independent tennis coaches like Nick Bollettieri and Robert Lansdorp, as well as with a private coach from Estonia, and coaches from the tennis federation's of France and the Czech Republic. The results found that tennis development should begin between the ages of six to eight. In the early stages of development it was found that fun, stroke technique, and learning how to play matches should be emphasized. Sport specialization should not occur before age 13 or 14. In order to attain expert performance players should amass 10 years and 10,000 hours of directed deliberate practice. Although researchers theorized that players do not benefit from practices lasting longer than four hours, coaches interviewed believe that it is essential to practice for five to six hours between the ages of 16-18 when the player is transitioning from junior tennis to professional tennis. A nurturing relationship with a coach and supportive, yet moderately involved parents, are also key elements to this development program. Most importantly, players must develop and maintain a love for tennis if they are to attain expert status. / 2031-01-01

Design of a Construction Safety Training System using Contextual Design MethodologyBaldev, Darshan H. 21 November 2006 (has links)
In the U.S., the majority of construction companies are small companies with 10 or fewer employees (BLS, 2004). The fatality rate in the construction industry is high, indicating a need for implementing safety training to a greater extent. This research addresses two main goals: to make recommendations and design a safety training system for small construction companies, and to use Contextual Design to design the training system. Contextual Design was developed by Holtzblatt (Beyer and Holtzblatt, 1998) in an effort to address the challenge of designing new systems. Ethnographic in nature, the Contextual Design methodology requires field data collection, requirements analysis, model building, visioning and story boarding, and prototyping. A sample of 12 participants consisting of 7 tradespersons, 3 forepersons, and 2 owners/ managers, was selected for data collection. The data was analyzed based on the Contextual Design approach and a training system prototype was designed. The results of this study are recommendations for safety in small construction companies, a low fidelity paper prototype of the training system, and recommendations on future use of Contextual Design for developing training systems. / Master of Science

Driveline : Moving infantry target (MIT)Hjortman, Robin, Harrysson, Kristian January 2016 (has links)
This report is part of a bachelor thesis implemented at Saab training systems AB in Huskvarna. It treats the concept development of the driveline on Moving infantry target, MIT. Today Saab has a problem in the shape of that their customers uses the wrong moment when tightening the cog belt of the driveline. As a consequence the cog belt has a high risk of snapping if it is too tight or pluck off if it is too loose. Thereto the electrical motors used in the MIT has gone out of production. The task boiled down to produce a number of proposals that improves the chucking or driveline solution together with finding a new electrical motor to replace the outdated one. A concept study was made containing detailed examinations together with Saab. To answer the problems questions, several product development methods were used, like Quality function deployment and Pugh’s matrix, to reach a final concept. The last concepts were modeled in a 3D-program for an easier comparison between their feasibility. The chosen solution consisted of two motors that via a gearing actuates the respective axle. By replacing the belt drive and choosing more lubrication free gears the maintenance is expected to be improved. In addition the product price is lowered by careful choices of components. The production of a prototype could not be implemented due to lack of time.

Distributed Interactive Simulation: The Answer to Interoperable Test and Training InstrumentationKassan, Mark W. 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / This paper discusses Global Positioning System (GPS) Range Applications Joint Program Office (RAJPO) efforts to foster interoperability between airborne instrumentation, virtual simulators, and constructive simulations using Distributed Interactive Simulation (DIS). In the past, the testing and training communities developed separate airborne instrumentation systems primarily because available technology couldn't encompass both communities' requirements. As budgets get smaller, as requirements merge, and as technology advances, the separate systems can be used interoperably and possibly merged to meet common requirements. Using DIS to bridge the gap between the RAJPO test instrumentation system and the Air Combat Maneuvering Instrumentation (ACMI) training systems provides a defacto system-level interoperable interface while giving both communities the added benefits of interaction with the modeling and simulation world. The RAJPO leads the test community in using DIS. RAJPO instrumentation has already supported training exercises such as Roving Sands 95, Warfighter 95, and Combat Synthetic Test, Training, and Assessment Range (STTAR) and major tests such as the Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation (JT&E) program. Future efforts may include support of Warrior Flag 97 and upgrading the Nellis No-Drop Bomb Scoring Ranges. These exercises, combining the use of DIS and RAJPO instrumentation to date, demonstrate how a single airborne system can be used successfully to support both test and training requirements. The Air Combat Training System (ACTS) Program plans to build interoperability through DIS into existing and future ACMI systems. The RAJPO is committed to fostering interoperable airborne instrumentation systems as well as interfaces to virtual and constructive systems in the modeling and simulation world. This interoperability will provide a highly realistic combat training and test synthetic environment enhancing the military's ability to train its warfighters and test its advanced weapon systems.

Previous issue date: 2016-03-29 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / Nos últimos anos, tem-se destacado o grupo de melancias de menor tamanho, de um a três quilos, denominadas de minimelancias. Essas melancias quando conduzidas em ambiente protegido, requerem sistema de condução na vertical e manejo de plantas para garantir elevada produtividade por área e frutos de qualidade. Com base nisso, esse trabalho teve por objetivos avaliar o desempenho de híbridos comerciais de minimelancia em diferentes espaçamentos, orientação do crescimento, e número de plantas. Para isso, foram conduzidos dois experimentos, cultivados sob ambiente protegido em substrato de fibra da casca de coco, com fertirrigação. A primeira etapa foi instalada utilizando o delineamento experimental de blocos ao acaso, em esquema fatorial 5 x 3, com quatro repetições. Os fatores avaliados foram: cinco híbridos de minimelancia (‘Beni Kodama’; ‘Ki Kodama’; ‘Smile’; ‘New Kodama’; e ‘Beni Makura’) e três espaçamentos entre plantas (E1= 0,35; E2= 0,50; E3=0,65). A segunda etapa foi conduzida utilizando o híbrido ‘Smile’ no delineamento experimental de blocos ao acaso, esquema fatorial 2 x 2, com oito repetições. O primeiro fator foi constituído de número de hastes por planta (1 e 2 duas hastes), e o segundo fator foi composto de número de plantas por vaso (1 e 2 plantas). Em ambas as etapas avaliaram-se características de produção, qualidade, assim como, parâmetros fisiológicos da planta. Na etapa 1 não houve interação significativa entre os fatores avaliados (híbridos e espaçamentos). Para híbridos é possível observar que houve diferença significativa apenas para massa fresca de frutos, onde ‘Smile’ apresentou melhor desempenho. Enquanto que para o fator espaçamento houveram diferenças, sendo que, espaçamentos maiores (0,50 m e 0,65 m) proporcionaram maior massa fresca dos frutos, área foliar, firmeza de frutos, diâmetros e percentual de frutos extragrandes. Já as maiores densidades (0,35 m) aumentaram a produtividade total e o índice de área foliar. Para a etapa 2 foi possível observar interação entre o manejo de hastes e o número de plantas/vaso, nas características de área foliar, índice de área foliar, massa seca da haste, massa de frutos, produtividade total, sólidos solúveis e percentual de frutos grandes. Os tratamentos conduzidos com duas hastes e uma planta/vaso proporcionaram altas produtividades sem prejudicar a qualidade dos frutos, tornando-se viável ao produtor. Dessa forma, recomendase o cultivo dos híbridos avaliados, no espaçamento de 0,50 m entre plantas, em fibra da casca de coco, aliado ao manejo de uma planta/vaso conduzida com duas hastes. / In recent years, it has highlighted the group of smaller watermelons, one to three kilos, called minimelancias. These watermelons when conducted in a protected cultivation, require training system vertically and management plans to ensure high productivity per area and fruit quality. Based on this, this study aimed to evaluate the performance of commercial hybrid minimelancia in different spacings, growth orientation, and number of plants. For this, two experiments were conducted, cultivated under protected environment in fiber substrate of coconut shell, with fertigation. The first stage was installed using the experimental design of randomized blocks in a factorial 5 x 3, with four replications. The factors evaluated were: five hybrids of minimelancia (‘Beni Kodama’, ‘Ki Kodama’, ‘Smile’, ‘New Kodama’, and ‘Beni Makura’) and three spacings between plants (E1 = 0.35; E2 = 0.50; E3 = 0.65). The second stage was conducted using the hybrid ‘Smile’ in the experimental design of randomized, factorial 2 x 2 with eight repetitions. The first factor is constituted by the number of stems per plant (stems 1 and 2) and the second factor consisting of the number of plants per pot (plants 1 and 2). In both stages were evaluated production characteristics, quality, as well as physiological parameters of the plant. In step 1, there was no significant interaction between the factors evaluated (hybrid and spacings). For hybrids is observed that there was a significant difference only for fresh fruit mass where ‘Smile’ performed better. While for spacings there were differences, and that greater spacing (0.50 m and 0.65 m) provided higher fresh fruit weight, leaf area, fruit firmness, diameter and percentage of oversized fruit. Already the highest densities (0.35 m) increased total productivity and the leaf area index. For step 2 was observed interaction between the management stems and the number of plants/pot, the leaf area characteristics, leaf area index, dry mass of the stem, fruit mass, total soluble solids and fruit percentage big ones. The treatments conducted with two stems and a plant/pot provided high yields without harming the quality of the fruit, making it viable for the producer. Thus, it is recommended the cultivation of hybrids, spaced 0.50 m between plants in coconut fiber shell, together with the management of a plant/vessel conducted with two stems. / FAPESP: 2013/05587-0

Real-Time High Resolution Digital Video for Range and Training ApplicationsMason, Andy, Gills, Steve 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The operator interface to a modern radar, sonar or weapons system trainer (WST) is typically one or more high-resolution video displays driven by PC’s or other workstations. The training system used to instruct and qualify operators for this type of mission critical application should be capable of recording RGB video data to a fine level of detail. Similarly, ground stations for Research, Development, Test and Evaluation (RDT&E) and Operational Test & Evaluation (OT&E) applications often utilize high-resolution workstation screens to display critical test data. And often, these workstation screens are located in mobile vans, on aircraft, or are otherwise remote from test conductors who need access to the same screen data. This paper presents a solution for the efficient digitization, storage, replay, and transmission of the data displayed on the high-resolution workstation screens commonly found in these types of training system applications.

Analys av teknik för implementering av 3D-ljud i Gizmo3D / Analysis of 3D sound technology for implementation in Gizmo3DKästel, David January 2005 (has links)
<p>I takt med att datorindustrin lyckas simulera både verklighetstrogna grafikvärldar och fysika-liska modeller i realtid ställs allt större krav på ljudupplevelsen. Gizmo3D är ett verktyg för att visualisera grafik som kan integreras i VR-applikationer. Att återskapa tredimensionell datorgrafik är vardagsmat, inte minst i en gigantisk spelindustri. Men vad är tredimensionellt ljud, 3D-ljud och hur kan man involveradet i Gizmo3D som inte har stöd för det? </p><p>Rapporten försöker svara på den frågan men även belysa 3D-ljudforskningens hela be-greppsvärld, då den utgör grund för att kunna implementera ett 3D- ljudsystem. Arbetet innebär främst studier av befintliga verktyg och teknologier. Dessa mynnar ut i rekommen-dationer och egna förslag till lösningar, på viss problematik, för implementering i ett scen-grafdrivet grafiksystem, som Gizmo3D utgör.</p>
