THE STUDY IN DIFFUSION MECHANISM BY VORONOI POLYHEDRON IN SODIUM TETRA-SILICATE MELT

Molecular dynamic simulation is carried out for Sodium tetra-silicate (NS4) melt at 1873 K and pressure of 0.1 MPa. The diffusion mechanism of Na atoms is investigated in terms of Voronoi polyhedron around network former and displacement of Na atoms between them. The simulation shows that Na atoms are not uniformly distributed through polyhedrons, but they mainly gather in nonbridging oxygen (NBO) and free oxygen (FO) polyhedrons. More than 75.22% of total Na atoms are place in NBO polyhedrons, although the number of NBO polyhedrons is only 22.27%. The two motion types give mainly contribution to Na diffusion: hopping of isolated Na atom or collective displacement. During 150 ps, the system comprises two separate regions: Na-poor regions formed by Si-O subnets and Na-rich regions formed by O2 clusters. The two regions have strongly different chemical composition, the density of Na atoms as well as motion type of Na atoms.

Convolutional neural network-based activity monitoring for indoor localization

Location specific services are widely used in outdoor environment and their indoor counterpart is gaining more popularity as well. There is no standardized technology exists for indoor localization, usually smart phone is used as a localization platform and the field strength of an existing radio frequency infrastructure is used as the location specific information. Smart devices are also equipped with several sensors capable of capturing the motion data of the device. Detecting the walking step, turn, stairs motion type can refine the indoor position using digital indoor map as a reference. The real-time recognition of the motion type is possible with a precisely constructed and trained convolutional neural network and therefore it can improve the stability of the localization.

The Research of Aesthetics of Type as Image in Motion-Targeting Video Poetics at Type Motion: Type as Image in Motion Exhibition in Taiwan

Characters are signs and symbols that record our thoughts and feelings and allow the documentation of events and history. Later, the appearance of motion images marked a new milestone in the use and application of characters. Not only were the original function of characters improved and enhanced, text that integrate sound and images are also able to communicate much more diverse and abundant information. This technique is commonly found in cinema, television, advertisement, and animation. Thanks to technological advances, the combination of characters, texts, or types and images once again changed how we read. It has also created new meaning for our time. Today, type image seems to have achieved an aesthetic autonomy of their own. This has a profound impact on image and art creation and human communication. The emergence of cinema art in the late 19th century brought motion into written media and greatly expanded the possibilities of art. In today’s world of instant communication media, text and images face unprecedented changes. Chinese characters are one of the most ancient writing systems in human history. Unlike western alphabet, each Chinese character has its own form, sound, and meaning. Chinese characters are a highly figurative cultural element. This essay takes Chinese characters and the works featured in the concrete poetry/sound poetry and fragment poetry categories in the National Taiwan Museum of Fine Arts “Type Motion: Type as Image in Motion” exhibition as the subject of study to examine the history of text and media and changes in the way we deliver information and communicate. This essay also provides an analysis of the relationship between text and motion image and the interdependency between culture and technology and media. The connections and differences between Chinese characters in different time and space is also investigated to highlight the uniqueness of the characters as a medium, its application in motion writing techniques and aesthetic forms. This essay focuses on the following four topics: Artistic expression and styles related to the development of type as image in motion. Video poetics: the association between poetics and video images, poetic framework, and analysis of film poetry. Structure, format, characteristics, and presentation of meaning in concrete poetry/sound poetry, and fragment poetry. how Chinese characters are used in Taiwan and the aesthetic features of type through the exhibited works.
