    A methodology is formulated and presented for the integrated structural dynamic analysis of space stations with controllable solar arrays and non-controllable appendages. The structural system flexibility characteristics are considered in the dynamic analysis by a synthesis technique whereby free-free space station modal coordinates and cantilever appendage coordinates are inertially coupled. A digital simulation of this analysis method is described and verified by comparison of interaction load solutions with other methods of solution. Motion equations are simulated for both the zero gravity and artificial gravity (spinning) orbital conditions. Closed loop controlling dynamics for both orientation control of the arrays and attitude control of the space station are provided in the simulation by various generic types of controlling systems. The capability of the simulation as a design tool is demonstrated by utilizing typical space station and solar array structural representations and a specific structural perturbing force. Response and interaction load solutions are presented for this structural configuration and indicate the importance of using an integrated type analysis for the predictions of structural interactions

    Continuing professional development of early years managers and practitioners working with children under 3 years of age: technical report

    This research into CPD provision for those working with children under 3 years of age was undertaken in the context of the National Review of the Early Years and Childcare Workforce (Scottish Executive, 2006) and the Scottish Parliamentary response (2006) which emphasised that: 'the area which requires most urgent investment is improving the skills level of the workforce, and that although further investment is required in the 3-5 sector, the under 3 sector is the most immediate priority' (SPEC, 2006, para 16). The findings of the research are interpreted in the light of the Standard for Childcare Practice (QAA, 2007) and the more recently published Early Years Framework (Scottish Government, 2008). The Early Years Framework defines early years as pre-birth to 8 years, though it highlights the need for 'a renewed focus on 0-3' (p5)

    Continuing professional development of early years managers and practitioners working with children under 3 years of age: executive summary

    Get PDF
    The Faculty of Education at the University of Strathclyde was commissioned by Learning and Teaching Scotland to undertake research into the continuing professional development provision (CPD) for early years practitioners and managers across Scotland, specifically focusing on provision for thoseworking with children under 3 years of age. The aim of the research was to identify ways in which those working in early years centres might be better supported through effective CPD opportunities, designed to meet the needs ofchildren and their families. The research was carried out between April and September 2008

    Integrated dynamic analysis simulation of space stations with controllable solar arrays (supplemental data and analyses)

    Get PDF
    Space station and solar array data and the analyses which were performed in support of the integrated dynamic analysis study. The analysis methods and the formulated digital simulation were developed. Control systems for space station altitude control and solar array orientation control include generic type control systems. These systems have been digitally coded and included in the simulation
