神光Ⅱ装置中空间滤波器系统的稳定性设计与分析

考虑到空间滤波器系统在激光装置中的稳定性要求，分析了影响稳定性的各种因素。对现行装置中的SF4空间滤波器系统进行振动模态测试，初步确定系统的工作状况，并结合振动理论明确系统稳定性的设计参数。利用有限元软件ANSYS对空间滤波器系统及相关的设计进行仿真验证计算。结果表明：SF4系统的一阶固有频率达到83Hz，与实验结果相符合，满足系统稳定性的要求；在系统中引入支撑不但能有效增加系统的刚度，同时能转移系统的振型；系统基础支撑平台的选择要求平台独立，并且选择较低的高度以便于控制上层光学元件的变形；在系统中的引入

Global and local challenges for best practices in assessment. The 9th Conference on the International Test Commission. Book of abstracts

The 9th International Test Commission Conference (ITC) took place at the Miramar Palace in San Sebastian, Spain, between the 2nd and 5th of July, 2014. The Conference was titled, “Global and Local Challenges for Best Practices in Assessment.” The International Test Commission, ITC (www.intestcom.org), is an association of national psychological associations, test commissions, publishers, and other organizations, as well as individuals who are committed to the promotion of effective testing and assessment policies and to the proper development, evaluation, and uses of educational and psychological instruments. The ITC facilitates the exchange of information among members and stimulates their cooperation on problems related to the construction, distribution, and uses of psychological and educational tests and other psychodiagnostic tools. This volume contains the abstracts of the contributions presented at the 9th International Test Commission Conference. The four themes of the Conference were closely linked to the goals of the ITC: - Challenges and Opportunities in International Assessment. - Application of New Technoloogies and New Psychometric Models in Testing. - Standards and Guidelines for Best Testing Practices. - Testing in Multilingual and Multicultural Contexts.

Construcción de una aplicación basada en modelos para la generación de guías de test integrados en la plataforma de ejecución de guías de práctica clínica AIDE-GTP

Este proyecto trata de abordar las transformaciones entre diferentes estándares para Test Informatizados, de manera automática, gracias a la Ingeniería dirigida por Modelos (MDE - Model Driven Engineer), para así obtener un estándar capaz de formar parte en una plataforma de ejecución de Guías de Práctica Clínica. Esto se consigue mediante la generación automática de Guías de Test, partiendo de Test Informatizados en los formatos estándar Aiken y Gift.
