A presentation of the 15cILLUSTRATION database and website, a searchable database of 15th-century printed illustrations developed by the 15cBOOKTRADE Project in collaboration with the Visual Geometry Group (VGG) at the Department of Engineering Science of the University of Oxford. 15cILLUSTRATION is the first comprehensive and systematic tool to track and investigate the production, use, circulation, and copying of woodblocks, iconographic subjects, artistic styles, within 15th-century printed illustrated editions. The paper illustrates the potential of the 15cILLUSTRATION website as a research support tool for art historians, book historians, philologists and historians of visual and material culture.

Courses in mechanical engineering usually introduce the theory of axial-flow turbo-machines in terms of simple velocity triangles representing the bulk flow of ideal compressible fluid through the blade passages. A distinctive practical difference, peculiar to steam turbines (ST), is the presence of liquid-water in the flow field. The steam wetness in such turbines is widely known to be doubly-damaging, leading to both loss of efficiency and to mechanical damage (erosion, etc.) of the machine components. Over recent decades, a whole new field of mechanical engineering science has evolved on the subject of wetness in steam turbines, and general practices have been established within the industry. This article reviews the general effects that are of major importance to the turbine designer/engineer, power plant operator, and especially to researchers in this field.

Many studies to find solutions for the optimum synthesis problems of linkage mechanisms for path, motion or function generation have appeared in the literature. However, their main focus has been on the development of optimization algorithms or synthesis methods without the handling of the defect problems or only with consideration of the same assembly mode. Hwang and Chen's pioneering work proposed a defect-free optimum synthesis method with constraint equations to eliminate order, circuit and branch defects for Stephenson III six-bar motion generators. However, their proposed constraint equations for the three types of defects are incomplete or not clear enough. In this discussion, we not only examine these faults but also offer the correct and complete constraints to eliminate the three types of defects.
