Proses digitalisasi naskah melalui media flipbook digital di Museum Bandar Cimanuk

ndramayu Regency has many ancient manuscripts that contain valuable information. Paper-based manuscripts are very easily damaged. Therefore, it is necessary to preserve ancient manuscripts. Switching to a digital flipbook is considered appropriate because it provides an interface that is similar to the original script. This study aims to describe the importance of preserving the cultural heritage of ancient manuscripts owned by the Bandar Cimanuk Indramayu Museum. Digitization can be an effort to preserve ancient manuscripts. The research used descriptive qualitative method. Data collection through observation, interviews, and documentation study. It is hoped that the research results in the form of flipbook development can be used as an effort to preserve ancient manuscripts that represent, protect, and exceed the physicality of ancient manuscripts. The conclusion of this study is that the ancient Legok Kolot manuscript is the identity and wealth of the Indramayu people, so it needs to be digitized so that the preservation of the script is maintained. The media transfer process at the Bandar Cimanuk Museum goes through three main stages, namely the pre-digitization process, the digitization process, and the post-digitization process. In its process, there are three important things that must be considered, such as source characteristics, product usability, and technological characteristics. The use of digital flipbooks as an effort to preserve ancient manuscripts is considered to protect, represent, and exceed the original ancient manuscripts

Reliability and Generalization of Gait Biometrics Using 3D Inertial Sensor Data and 3D Optical System Trajectories

Particularities in the individuals’ style of walking have been explored for at least three decades as a biometric trait, fueling the automatic gait recognition field. Whereas, gait recognition works usually focus on improving end-to-end performance measures, and this work aims at understanding which individuals’ traces are more relevant to improve subjects’ separability. For such, a manifold projection technique and a multi-sensor gait dataset were adopted to investigate the impact of each data source characteristics on this separability. The assessments have shown it is hard to distinguish individuals based only on their walking patterns in a subject identification scenario. In this scenario, the subjects’ separability is more related to their physical characteristics than their movements related to gait cycles and biomechanical events. However, this study’s results also points to the feasibility of learning identity characteristics from individuals’ walking patterns learned from similarities and differences between subjects in a verification setup. The explorations concluded that periodic components occurring in frequencies between 6Hz and 10Hz are more significant for learning these patterns than events and other biomechanical movements related to the gait cycle, as usually explored in the literature.

Self-limiting earthquake dynamics and spatio-temporal clustering of seismicity enabled by off-fault plasticity

Earthquakes are among nature’s deadliest and costliest hazards. Understanding mechanisms for earthquake nucleation, propagation, and arrest is key for developing reliable operational forecasts and next generation seismic hazard models. While significant progress has been made in understanding source processes in linear elastic domains, the response of the rocks near the fault is complex and likely to be inelastic due to the extreme stresses and deformations associated with fault slip. The effect of this more realistic fault zone response on seismic and aseismic fault slip is poorly understood. Here, we simulate sequence of earthquake and aseismic slip of a fault embedded in an elastic-viscoplastic bulk subject to slow tectonic loading. We show that off-fault plasticity significantly influences the source characteristics. Specifically, off-fault plasticity may lead to partial ruptures and emergence of spatial segmentation as well as hierarchical temporal seismic clustering. Furthermore, co-evolution of fault slip and off-fault bulk plasticity may lead to heterogeneous rupture propagation and results in pockets of slip deficit. While the energy dissipated through plastic deformation remains a small fraction of the total energy budget, its impact on the source characteristics is disproportionally large through the redistribution of stresses and viscous relaxation. Our results suggest a new mechanism of dynamic heterogeneity in earthquake physics that can be active for both small and large earthquakes and may have important implications on earthquake size distribution and energy budget. Furthermore, this plasticity-induced self-limiting crack dynamics may be relevant for other dynamic fracture applications and design of dynamically tough materials.
