Dynamic Hand Gesture-Based Person Identification Using Leap Motion and Machine Learning Approaches

Computers, Materials & Continua 2024年第4期79卷 1205-1222页

Person identification is one of the most vital tasks for network security. People are more concerned about theirsecurity due to traditional passwords becoming weaker or leaking in various attacks. In recent decades, fingerprintsand faces have been widely used for person identification, which has the risk of information leakage as a resultof reproducing fingers or faces by taking a snapshot. Recently, people have focused on creating an identifiablepattern, which will not be reproducible falsely by capturing psychological and behavioral information of a personusing vision and sensor-based techniques. In existing studies, most of the researchers used very complex patternsin this direction, which need special training and attention to remember the patterns and failed to capturethe psychological and behavioral information of a person properly. To overcome these problems, this researchdevised a novel dynamic hand gesture-based person identification system using a Leap Motion sensor. Thisstudy developed two hand gesture-based pattern datasets for performing the experiments, which contained morethan 500 samples, collected from 25 subjects. Various static and dynamic features were extracted from the handgeometry. Randomforest was used to measure feature importance using the Gini Index. Finally, the support vectormachinewas implemented for person identification and evaluate its performance using identification accuracy. Theexperimental results showed that the proposed system produced an identification accuracy of 99.8% for arbitraryhand gesture-based patterns and 99.6% for the same dynamic hand gesture-based patterns. This result indicatedthat the proposed system can be used for person identification in the field of security.

Random fractal-based computational design of an ice-ray (IR) lattice shell structure

引用

Frontiers of Architectural Research 2024年第2期13卷 406-424页

作者： Iasef md Rian Department of Architecture Xi'an Jiaotong-Liverpool UniversitySuzhou 215123China

Chinese ice-ray (IR) lattices, known for their intricate and visually fascinating random patterns as decorative elements in traditional 18th-century Chinese window design, exhibit underlying stiffness as latticed window fences. Such unique patterns represent a new morphology within the family of stochastic lattices. However, the latent structural potential within the random patterns of ice-ray lattices remains largely unexplored, particularly in the context of lattice shell design. This study systematically studies the geometric qualities of ice-ray lattice patterns and develops an algorithm to model these patterns for ice-ray lattice shell design. Subsequently, it assesses the structural feasibility and effectiveness of these lattice shells in comparison to conventional gridshells. The practicality of constructing random lattice shells using digital fabrication tools is also explored. Employing fractal geometry as a foundational framework, this research not only offers insights into the potential of ice-ray lattices for innovative lattice shell design but also introduces a new structural morphology to the field, expanding the possibilities of incorporating stochastic patterns in lattice shell design. Ultimately, it opens up new opportunities for innovative lattice shell designs, emphasizing the potential of stochastic patterns in structural applications.

Potential role of tubulin glutamylation in neurodegenerative diseases

Neural Regeneration Research 2024年第6期19卷 1191-1192页

作者： Abdullah md.Sheikh Shatera Tabassum Department of Laboratory Medicine Shimane University Faculty of Medicine

The differentiation of neuronal stem cells into mature neurons is a complex process that involves both structural and functional changes. As cells undergo differentiation, there are notable functional changes, including the expression of various transcription factors, cytokines, and neurotransmitiers. Additionally, structural changes occur as the cells develop various processes from the cell body and establish synaptic contacts with other cells.
