O presente estudo é constituído por três experimentos diferentes, que tem como ponto central a investigação do método da PSE da sessão. No primeiro experimento foi avaliada a validade do método da percepção subjetiva do esforço (PSE) da sessão para a quantificação da carga interna de treinamento (CIT) no Tênis. Neste experimento foram monitoradas 384 sessões de treinamento técnico/tático, 23 partidas simuladas e 13 partidas oficiais. A CIT foi calculada utilizando dois métodos de quantificação da CIT: o método da PSE da sessão e o método proposto por Edwards, baseado no comportamento da frequência cardíaca. Posteriormente, foi calculado o índice de correlação entre os dois métodos. Foi detectada correlação individual entre os métodos (r = 0,58 - 0,89; p<0,01). Também foi observada correlação entre os métodos para as sessões de treinamento técnico/tático (r = 0,74), os jogos simulados (r = 0,57) e os jogos oficiais (r = 0,99). Estes resultados sugerem que o método da PSE da sessão é uma alternativa válida, não invasiva, para quantificar a CIT de tenistas. O segundo experimento, descreve o padrão de distribuição da intensidade utilizada por tenistas durante a pré-temporada e no início do período competitivo...

Virtual Reality (VR) technologies have potential for training applications, providing advantages in terms of cost reduction, safety and time. The success of a VR package for training relies greatly on its capacity to provide a real‐time immersive effect to the user. For the sake of realism a simulated instrument must be able to compute the dose rate in the virtual environment with equivalent accuracy and in about the same time as the real instrument. Further, visual rendering must be smooth in order to provide a fluid scenario movement. This paper presents a VR based prototype to accurately model the dosimetry of radioactive and nuclear sources, to be selected from a wide library. Dose measurements should reflect local conditions, i.e., presence of shielding materials (with shape and type selected from a library) and accept sources irrespectively of their dimensions and shapes. The scope of the application is to train civil protection officers, including border / customs officers, fire‐fighters, local police, etc. and let them acquire the skills necessary for Nuclear Security activities. These people have a wide professional profile and are not experts in the detection of nuclear and radioactive materials. A VR based dosimetry training application involves the creation of a 3D realistic scenario (e.g....

Due to growing operational constraints accelerated by the Global War on Terror, the United States Navy is looking for alternative methods of training to maintain its force in a high status of readiness. Updates in technology over the last decade have prompted Navy officials to take the initiative to update its training technologies. Computer-Based Instruction provides alternative means of training so that the training of war-fighters can be accomplished efficiently and effectively, saving the U.S. Navy time and resources while maintaining a high state of readiness. The goal of this thesis is to combine the principles of Instructional Design Systems (ISD) technology and advanced Simulation in order to produce a multimedia training capability for Navy and Marine Corps Officers. Specifically this thesis applies ISD principles to engineer and improve the Anti-Terrorism Force Protection (AT/FP) Officer Course Level II (ATO Level II Course) lessons for use by Navy and Marine Corps officers. The SavageStudio scenario generation application, originally designed for assessment of force protection measures in a port environment, is used to allow students to develop simulation lessons for this course. The final product of this thesis is a training course consisting of two lessons combining Computer- Based Training and Simulation providing interactive lessons and exercises...

Approved for public release; distribution is unlimited; This thesis describes the formative evaluation of the Tactical Patrol Craft Trainer (TPCT) during the implementation stage. The TPCT is an interactive multi-media computer based trainer designed to deliver a full fidelity and analog video training scenario to Prospective Commanding Officers (PCOs) of the Coastal Patrol Craft (PC) class ship. The system is designed to induce stress while enhancing autonomous decision making skills. The methodology involved six survey instruments, observation, and interviews with the trainees. The data show that the TPCT induces stress as intended, the user interface is appropriate, and the trainees perceived the training as valuable. Several improvements are noted in the course structure, user interface, and system application. Recommendations are made for more scenarios, additional applications of the technology, and evaluation of training effectiveness after the final implementation of the system

Approved for public release; distribution is unlimited.; Documents include Paper and Powerpoint Presentation.; The Coalition Battle Management Language (C-BML) is a common language for expressing and exchanging plans, orders, requests, and reports across command and control systems, modeling and simulation systems, and robotic systems. A Phase 1 C-BML Specification is being drafted in preparation for balloting later this year. The C-BML information exchange structure and content portion of the specification provides a means to express plans, orders, reports, and requests using the Extensible Markup Language (XML). The Military Scenario Definition Language (MSDL) is an approved SISO standard (SISO-STD-007-2008, October 2008) that specifies an XML-based language designed to support military scenario development. The standard provides the modeling and simulation community a common mechanism for verifying and loading military scenarios, the ability to create a military scenario that can be shared between simulations and C4I devices, a way to improve scenario consistency between federated simulations, and the ability to reuse military scenarios as scenario descriptions are standardized throughout the Army, Joint, and international communities and across simulation domains; e.g....

Approved for public release; distribution is unlimited; The Office of Naval Research Future Naval Capabilities, the Defense Technology Area Plan from 2005 and the Department of Defense Science and Technology Priorities for FY13-17 all share a focus on systems to promote warfighter performance. The goal of these systems is to improve effectiveness across a range of multiple missions, while providing training techniques that enhance fundamental cognitive abilities, institute techniques to reduce training time and training costs, maximize the training impact, as well as to provide tools and techniques to achieve routine and engaging scenario-based training. Intelligent tutoring systems (ITS) can address these goals. This work describes an ITS created for use in training naval surface warfare officers (SWOs) in air defense. A description of the learning theories applied in the development of the system, as well as a brief history of ITSs and the methodology that was utilized in developing this ITS is provided. A TCP/IP connection was established between this tutor and TAO Sandbox, a simulator utilized by Surface Warfare Officer School to train SWOs. Through a designed experiment, it was demonstrated that this ITS provides statistically significant training to its intended audience.

A questão central desse trabalho é a formação continuada de professores em educação ambiental. A emergência da crise ambiental fez-nos repensar nossa maneira de ser e agir no mundo e, diante do inconformismo com os processos de exclusão e desigualdades que a sociedade hegemônica produz, procura-se contribuir para transformá-la. Em relação à formação docente, tem-se valorizado os conhecimentos técnicos e metodológicos em detrimento aos de formação política e social do docente. Nesse cenário, a formação ambiental em cursos iniciais de professores tem se mostrado deficiente, havendo uma necessidade de formação continuada na área. Diversos autores propõem que nesses cursos se trabalhe com a educação ambiental numa perspectiva crítica, que aponta o cotidiano da escola como um meio de trazer significado ao processo ensino-aprendizagem. A partir desse quadro foi pensada uma formação continuada de professores em educação ambiental, trabalhando-se com uma Unidade de Conservação vizinha à instituição educativa selecionada para estudo, como possibilidade do resgate do cotidiano escolar. Assim, a pesquisa analisou o processo de formação continuada de professores em educação ambiental em uma escola de ensino fundamental do entorno do Parque Estadual da Serra do Brigadeiro...

CHDS State/Local; There is a great opportunity for collaborative learning when agencies conduct emergency preparedness exercises together. If different members of the community contribute to the development of these exercises, then this learning benefits the entire population. As it stands, preparedness exercises are being conducted with minimal regard to recommendations from previous exercises and real-world events. Along with the incorporation of intelligence into these exercises, the objectives should promote a more inclusive design process based on focused relevance, encouraging agencies to view themselves more as members of the greater community rather than individual entities. Terrorist organizations learn from past failures as well as successes, and emergency responders should strive to parallel this learning in order to develop tactical improvements. Emergency responders need to promote the idea of intelligence-driven exercise design in order to support community resilience through collaborative training. Municipalities should spearhead this effort, supported financially by the private sector. With this fusion of intelligence and collaborative exercise design, we can learn from the fires of yesterday and prepare for the emergencies of tomorrow.; Lieutenant...

The AEGIS Cruiser Air-Defense Simulation is a program that models the operations of a Combat Information Center (CIC) team performing the ADC duties in a battle group using Multi-Agent System (MAS) technology implemented in the Java programming language. Set in the Arabian Gulf region, the simulation is a top-view, dynamic, graphics-driven software implementation that provides a picture of the CIC team grappling with a challenging, complex problem. Conceived primarily as a system to assist ships, waterfront training teams, and battle group staffs in ADC training and doctrine formulation, the simulation was designed to gain insight and understanding into the numerous factors (skills, experience, fatigue, aircraft numbers, weather, etc.) that influence the performance of the overall CIC team and watchstanders. The program explores the team's performance under abnormal or high intensity/stress situations by simulating their mental processes, decision-making aspects, communications patterns, and cognitive attributes. Everything in the scenario is logged, which allows for the reconstruction of interesting events (i.e. watchstander mistakes, chain-of-error analysis) for use in post-scenario training as well as the creation of new, more focused themes for actual CIC team scenarios. The simulation also tracks various watchstander and CIC team performance metrics for review by the user.; Lieutenant...

Approved for public release; distribution is unlimited; The CyberCIEGE project seeks to create an alternative to traditional Information Assurance (IA) training and education approaches by developing an interactive, entertaining commercial-grade PC-based computer game that teaches IA concepts while simultaneously entertaining the player. The game provides a robust, flexible and extensible gaming environment where each game instance is based on a fully customizable scenario. These customized scenarios produce game simulations that are tailored to meet a player's specific IA training needs, thus providing personalized, focused IA training at a minimum cost in both dollars and time. Additionally, the interactive game simulations, provided by the CyberCIEGE game, create an entertaining and realistic training environment for the player. Finally, the ability to load the game onto, and execute it from a PC allows IA training to be conducted practically anywhere, i.e. at home, or while traveling. To demonstrate this capability, this thesis developed a customized scenario designed to educate players in secrecy issues concerning the connection of an internal corporate network with the Internet. Additionally, this thesis produced Scenario Definition Files (SDFs) designed to test the game engine to determine if it would produce results that met the SDF developer's expectations and that the simulated game environment was realistic.; US Marine Corps (USMC) author.

Approved for public release; distribution is unlimited; The purpose of this paper is to present and evaluate a tool designed to assess the performance of military teams participating in complex military training exercises and to investigate the effectiveness of simulator training and live training from the matching of inherent stressors. Specifically, this study evaluates a tool that has been used by Norwegian military subject matter experts (SMEs) to assess the performance of eight cadet teams at the Royal Norwegian Naval Academy (RNoNA) during two separate 4-hour simulator exercises and a 48-hour live exercise. The resulting positive Spearman rank correlation coefficients between team performance assessments in the simulator exercises and the live exercise were strongest when the simulator scenario emphasized the stressors inherent in the live exercise and weakest when the simulator scenario did not facilitate the task demands in the live exercise. The study showed that (1) team performance measured in simulator training exercises can predict performance in a subsequent live training exercise, and (2) that scenario-based simulator training can realistically and effectively represent training demands for live operations. Our findings show the RNoNA tool can be easily applied to team training exercises and provide a meaningful evaluation of a team's future performance.; Outstanding Thesis; Lieutenant Commander...

Approved for public release, distribution is unlimited.; The Department of Defense relies on modeling and simulation for a variety of purposes, including joint exercise training, developing and evaluating doctrine and tactics, and studying weapon system effectiveness. Advances in technology have made the achievement of technically and visually accurate simulations possible, but little has been done to present realistic scenarios while supporting user interaction. This dissertation describes a multi-agent interactive simulation engine for generating interactive scenarios or stories. A general-purpose multi-agent system simulation architecture, called a Connector-based Multi-Agent System (CMAS) is developed and presented, along with a software agent communication and coordination mechanism. In this architecture, stories are generated through discovery as a by-product of agent interactions, rather than being fixed in advance. The ensuing story adapts to the user's interventions and is closely aligned to the goals of the agents. The multi-agent system design of the story engine has resulted in a data-driven simulation engine, which is domain independent and highly scalable. The story engine is fielded as the underlying simulation engine behind the U.S. Army's America's Army: Soldiers project. The instantiation of the story engine as it applies to Soldiers is presented. As a component of Soldiers...

This work examines the use of two-way training to efficiently discriminate the channel estimation performances at a legitimate receiver (LR) and an unauthorized receiver (UR) in a multiple-input multiple-output (MIMO) wireless system. This work improves upon the original discriminatory channel estimation (DCE) scheme proposed by Chang where multiple stages of feedback and retraining were used. While most studies on physical layer secrecy are under the information-theoretic framework and focus directly on the data transmission phase, studies on DCE focus on the training phase and aim to provide a practical signal processing technique to discriminate between the channel estimation performances (and, thus, the effective received signal qualities) at LR and UR. A key feature of DCE designs is the insertion of artificial noise (AN) in the training signal to degrade the channel estimation performance at UR. To do so, AN must be placed in a carefully chosen subspace, based on the transmitter's knowledge of LR's channel, in order to minimize its effect on LR. In this paper, we adopt the idea of two-way training that allows both the transmitter and LR to send training signals to facilitate channel estimation at both ends. Both reciprocal and nonreciprocal channels are considered and a two-way DCE scheme is proposed for each scenario. For mathematical tractability...

In the last decade, scenario-based serious-games have become a main tool for learning new skills and capabilities. An important factor in the development of such systems is the overhead in time, cost and human resources to manually create the content for these scenarios. We focus on how to create content for scenarios in medical, military, commerce and gaming applications where maintaining the integrity and coherence of the content is integral for the system's success. To do so, we present an automatic method for generating content about everyday activities through combining computer science techniques with the crowd. We use the crowd in three basic ways: to capture a database of scenarios of everyday activities, to generate a database of likely replacements for specific events within that scenario, and to evaluate the resulting scenarios. We found that the generated scenarios were rated as reliable and consistent by the crowd when compared to the scenarios that were originally captured. We also compared the generated scenarios to those created by traditional planning techniques. We found that both methods were equally effective in generated reliable and consistent scenarios, yet the main advantages of our approach is that the content we generate is more varied and much easier to create. We have begun integrating this approach within a scenario-based training application for novice investigators within the law enforcement departments to improve their questioning skills.

Hi-tech manufacturing uses sophisticated and capital intensive processes that require a highly skilled workforce. Fluctuating demand leads to either a shortage of skilled workers that causes unmet demand or an excess of skilled labor that causes worker idleness. This mismatch in the available and required skillsets is a source of potential loss for the organization. This thesis formulates an industry-motivated workforce planning and facility utilization problem as a two-stage stochastic recourse program that considers fluctuating demand over a long planning horizon and includes business and labor rules, e.g., hiring, firing, overtime, cross-training, and shift swapping, that govern the structure of the workforce. Solutions to this problem are computed using a scenario-based approach and indicate that the cost of workforce formation can be significantly reduced by using the recourse problem.
