For rock engineering projects, the cutting and fragmenting of rocks has attracted much attention. Exploring the fracture characteristics of rocks is helpful in achieving efficient and sustainable excavation for mining and tunneling engineering. The fracture toughness of rocks is a crucial mechanical indicator that weighs the initiation and extension of cracks during the breaking process.…
Alternating current field measurement (ACFM) technology has been used for sizing underwater structure cracks. However, conventional ACFM is more sensitive to cracks perpendicular to the induced current than cracks with other angles. In this paper, a rotating alternating current field measurement (RACFM) method and underwater test system are present for the detection of arbitrary-angle cr…
This book is open access under a CC BY 4.0 license. This book investigates the impact of vote buying on the accountability of democratic institutions and policy representation in newly democratic countries, with a focus on Indonesia. In doing so, the book presents a wide-ranging study of the dynamics of vote buying in Indonesia’s young democracy, exploring the nature, extent, determinants, t…
This open access book is the first publication to provide a comparative framework for the study of martial culture and historical martial arts in Europe and Asia, in particular in Italy and China. Due to the interdisciplinary nature of martial studies, contributors to this volume include historians, archeologists, art historians, scholars of fencing literature, metallurgists, as well as contemp…
