MMOG technology offers a cost effective alternative to existing training methodologies. Existing first responder WMD training often uses traditional in-residence classes. These current training methods are expensive, lack standardization, and do not have provable outcomes. Scaling up existing training to meet the needs of millions of responders would be cost prohibitive. Modern information technologies such as MMOGs offer a safe, efficient, effective and fun alternative mechanism to deliver training. MMOGs could scale to meet the volume of training need at a fraction of the cost of traditional methods. The DoD has proven the effectiveness of simulation games as a training tool, and the use of gaming and simulations is recognized in academia. / Captain, Seattle Fire Department

RESEARCH REPORT SUBMITTED TO THE FACULTY OF EDUCATION, UNIVERSITY OF THE W1TWATERSRAND, JOHANNESBURG, IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF EDUCATION JOHANNESBURG 1986 / This study investigated the effectiveness of a simulation game in the teaching of history to secondary school pupils at matriculation level. History as taught in the schools has for a long time been a source of criticism and many educationists are perturbed by this fact. It is with this in mind that this investigation has been undertaken. In order to facilitate the investigation fifty matriculation pupils were divided into two unmatched groups. One group, the experimental group, was exposed to instruction by the simulation technique and the other, the control group was exposed to instruction by conventional methods. Both groups wrote the same achievement t»st and the results showed that the control group's achievement was better than that oi the experimental group. There are various reasons for this result as the investigation will indicate. It is apparent from the result that using non-equivalent groups for the investigation could not substantiate the hypothesis.

Theoretical modeling and simulation are two common approaches to the study of land use change. While theoretical models are often limited by the simplicity in their assumptions, simulations are mostly low in generalization due to their specificity in applications. The integration of these two approaches will thus help us to model more closely the reality by having a firm theoretical foundation for real-life simulation. In the present research, a theory-based cellular automata (CA) simulation is proposed to simulate the changes of land uses. The land use change generally involves urban development and urban redevelopment processes. Rent gap theory is selected as the theoretical model to describe the mechanism of urban redevelopment. On the other hand, relevant conditions related to urban development are incorporated into the simulation of new development because rent gap theory is inadequate in accounting for all mechanisms that are working together to shape the pattern of land use change. In order to perform CA simulation under random fluctuation in time, stochastic formulation of the rent gap theory is first made in the form of a build up value equation to seek for the time of appearance of rent gap. The time of urban redevelopment depends on the appearance of rent gap while the time of urban development depends on the conditions of local characteristics and government policy. To substantiate the theoretical arguments, the land use change of Hong Kong in the period of 1966--2001 is selected as a case study. For the pattern of future development of Hong Kong, the simulation is carried out up to 2016. It also serves as a basis for the evaluation of the integrative utilization of a theoretical model and a simulation method. This research demonstrates that the appropriate integration of a theoretical model and a simulation method is beneficial to the study of land use change. / Tsang Shun Wai. / "July 2007." / Advisers: Yee Leung; Tung Fung. / Source: Dissertation Abstracts International, Volume: 69-01, Section: A, page: 0334. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 215-241). / Electronic reproduction.

Climatic trends in most parts of the world show a significant increase in rainfall amount, intensity and its frequency. Similarly, these trends are likely to continue in future as well. The major catastrophe caused by these rainfall trends comes as flooding, which is getting harder to predict, and mainly over the mountainous regions. Modelling these extreme rainfall events is crucial, which needs better forecasting skills and more understanding of existing Numerical Weather Prediction (NWP) modelling setup. Although, recent developments in NWP models increase the capabilities to simulate rainfall more precisely but the strengths and weaknesses of model need to be evaluated based on climatic conditions, terrain characteristics -- which include landuse, topography, new physical schemes and static datasets. Therefore, we have conducted comprehensive sensitivity and qualitative analysis with a numerous model setup, physical schemes and terrain datasets. / We contemplate various physical parameterizations and updated terrain datasets to simulate the rainfall over the complex topography using WRFV3-ARW modelling system. Additionally, the impact of topography and landuse on rainfall are discussed in detail along with a several combinations of newly available land surface, planetary boundary layer (PBL), cumulus, and cloud microphysics (MP) schemes. As a case study, we select the north region of Pakistan, which includes Khyber-Pakhtunkhwa (KPK) province and part of Hindukush-Karakoram-Himalaya (HKH), and this region have diversified the landscape and complex topographic features. For the sake of better understanding and comparative discussions, we study three extreme rainfall events; two of them occurred during monsoon period (i.e., July), while one in post monsoon period (i.e., September). / WRF-ARW 3.5.1 model is tuned and tested with GFS0.5 and CFSR/CFSv2 as forcing and lateral boundary conditions with a number of parameterization schemes. Similarly, to minimize the errors induced by terrain features, we apply wind correction and drag parameterizations. Furthermore, 3-arc-second hydrologically corrected SRTM digital elevation model (DEM), modified MODIS IGBP 30-arc-second, MODIS 15-arc-second and GLCNMO2008 landuse datasets were also integrated to WRF along with default datasets in WRF modelling system. / We verify the simulated rainfall by using observed, the Tropical Rainfall Measuring Mission (TRMM) and the Climate Prediction Centre morphing method (CMORPH) rainfall datasets. The GIS-based verification technique, called fisher-net is also introduced which is more compatible and flexible with other tools as well. / 隨著全球氣候變化的加劇，強暴雨極端天氣事件呈現突發、多發、併發的特點，其頻次、強度、持續時間、籠罩範圍近年來均呈現急速上升的趨勢。如何構建高時效性、高精度和高可用的極端天氣事件模擬工具，已經成為災害應急管理與回應等領域迫切需要解決的關鍵科學問題。作為極端天氣事件類比的核心，數值氣象模型對極端暴雨事件的模擬能力日益完善；然而，到目前為止，氣象模型的可靠性和有效性評價仍是其推廣應用的關鍵，特別是如何顧及土地利用類型、地形、新型物理機制和多源靜態資料庫前提下的模型可靠性評價仍面臨很多挑戰。因此，本文提出了顧及不同物理機制、地形特徵的模型構建、模型敏感性評價和定量分析方法。 / 首先，本文在顧及不同的物理參數和地形特徵的基礎上，利用WRFV3-ARW 建模系統實現了對複雜地形特徵下降雨過程的類比與分析。在此基礎上，本文充分考慮和利用新的土地下墊面、行星邊界層、積雲以及雲微物理機制，以詳細分析了地形和土地利用類型對降雨影響。實驗選用具有複雜地形結構和特徵的巴基斯坦北部的Khyber-Pakhtunkhwa (KPK)省和部分Hindukush-Karakoram-Himalaya (HKH) 區域；為了獲取更充分的分析結果，本位對該實驗區域內三次極端降雨事件進行了模擬和分析，包括季風期（例如七月）的兩次降雨事件和季風期過後（例如九月）的一次降雨事件。 / 其次，本文利用GFS0.5 和 CFSR/CFSv2 作為強迫和側邊界條件，設置多參數方案對WRF-ARW 3.5.1 模型進行了優化和測試。與此同時，為了降低由地形特徵導致的類比誤差，本文引入了風向糾正參數和風阻參數。除此之外，本文充分利用了水文糾正過後的3 弧秒精度的SRTM DEM 資料、30 弧秒精度的MODIS IGBP 資料、15 弧秒精度的MODIS 資料、GLCNMO2008 格式的土地利用資料、以及WRF 建模系統的預設資料，支撐WRF 的建模過程。 / 最後，為了驗證本文實驗結果的可靠性，本文利用TRMM 獲取的實測降雨量資料以及TRMM 提供的降雨資料庫驗證，基於GIS 的漁網驗證法，對上述模擬結果進行了詳細的分析 / Sultan, Shahzad. / Thesis Ph.D. Chinese University of Hong Kong 2015. / Includes bibliographical references (leaves 111-125). / Abstracts also in Chinese. / Title from PDF title page (viewed on 09, September, 2016). / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only.

Based on the combined surface and volume RWG (Rao-Wilton-Glisson) basis functions, a simulator of a patch antenna on a finite dielectric substrate using the Method of Moments (MoM) has been implemented in Matlab. The metal surface is divided into planar triangular elements whereas the (inhomogeneous) dielectric volume is divided into tetrahedral elements. The structure under study is comprised of a typical patch antenna consisting of a single patch above a finite ground plane, and a probe feed. The performance of the solver is studied for different mesh configurations. The results obtained are tested by comparison with the commercial ANSOFT HFSS v8.5 and WIPL-D simulators. The former uses a large number of finite elements (up to 30,000) and adaptive mesh refinement, thus providing the reliable data for comparison. Behavior of the most sensitive characteristic ¡V antenna input impedance ¡V is tested, close to the first resonant frequency. The error in the resonant frequency is estimated at different values of the relative dielectric constant ƒÕr, which ranges from 1 to 20. The reported results show reasonable agreement. However, the solver needs to be further improved.
