Using persona as lenses for a reference model

This paper investigates the value of persona in relation to a conceptual product: the ENVRI reference model designed for environmental research infrastructures. Three personas have been created to understand the use of the model and the challenges faced when applying it. Personas helped identify the level of support required by different users, prioritise the audience to address first, and revealed what aspects of the model are important to different audiences. We have made significant progress in understanding how to improve communication about the model to each persona

Thermo-structural analysis manual.

This second volume of the Thermo-Structural Analysis Manual considers additional problems in the field of thermal and mechanical stress analysis not fully treated in Volume 1. Special emphasis is given to nonlinear analysis of beams and plates and to axisymmetric thermo-elastic analysis of thin shells. Following the format of Volume 1, nondimensional graphs, formulas and tables are developed where feasible. For clarification of the analytical techniques and the use of the numerical data, illustrative examples are given. The following problems are treated: (1) large deflection analysis of straight elastic beams with axial end restraint and axial end loads coupled with transverse loading and temperature, (2) approximate determination of the axIal end loads and deformations in heated beam columns with initial eccentricities, (3) approximate solutions for the buckling of eccentric columns accommodating nonlinear stress strain laws, (4) axisymmetric large deflections of circular plates subjected to thermal and mechanical loads, and (5) axisymmetric thermo-elastic analysis of thin shells."October 1962"Includes bibliographical references.This second volume of the Thermo-Structural Analysis Manual considers additional problems in the field of thermal and mechanical stress analysis not fully treated in Volume 1.
