Calligraphy Brush Trajectory Control of by a Robotic Arm

This study proposed a calligraphy brush trajectory model for the behavior of brush movements and provided the three-dimensional handle coordinates for a robotic arm to write calligraphy. This study dealt with basic footprints and bent lines of calligraphy and proceeded as follows. The shape of brush footprints on paper was measured, which provided the positions of the brush relative to its handle. These brush footprints were scanned and corrected for skew using the Direct Linear Transformation. The outer frame of each basic footprint was characterized using Bézier curves. Bent lines were drawn to derive the brush trajectory model, and it was used to derive the relationship between the trajectories of the brush and handle. By characterizing the changes in the footprints with handle displacement, we obtained the relationship between the handle coordinates and the position and shape of the brush footprints. The written characters were evaluated based on their size, position, and stroke balance, with a maximum score of 100 in each category. The average score of the “Yong” character written using our brush trajectory model was approximately 94 points; when the handle coordinates were fixed to the center of each footprint, the average score was only 88 points.

On approximately dual frames for Hilbert C*-modules

In this paper we discuss approximately dual frames for a frame or an outer frame of a Hilbert C*-module. We show that every frame or an outer frame, up to a scalar multiple, is approximately dual to itself. This enables us to get a canonical dual frame of a given frame (xn)n as a limit of approximately dual frames defined by (xn)n.

Mechanical Response of outer Frame in TFG Model with Connecting Diamond-Shaped Frame

In tuning fork micro-gyroscopes, two outer frames are connected indirectly or directly by using the linking elements. Their driving vibration should be exactly opposite to cause the opposite sensing modes in the direction perpendicular to driving one. These opposite driving vibrations are obtained by using a mechanical structure named the diamond-shaped frame. This paper reports mechanical responses of two outer frames in a proposed model of tuning fork gyroscope when an external force with different types is applied to them. The results show that the presence of a diamond-shaped frame guarantees the absolute anti-phase mode for the driving vibrations of outer frames.

The Feeling of Seeing: Factical Life in Salsa Dance

Salsa dancing, a partnered dance premised on the felt sense of connection, is well suited to an exploration of Henry’s radical phenomenology of immanence and Heidegger’s facticity of life. Birthed in social celebratory contexts, salsa carries a particular motile freedom. What matters most is not how the dance movements are created from an outer frame of reference, but the experience of interactive responsiveness that emerges from unanticipated acts of giving life to another. Connecting to one’s partner and exuding a presence filled with life is revealed in an indepth interview with two-time world champion salsa dancer, judge, choreographer and coach, Anya Katsevman. This interview attempts to invoke the kinetic, kinesthetic and affective registers of the lividness and livingness of salsa dancing. As a phenomenological inquiry into factical life, the inter-view is presented not so much as a matter of shared perspectives or viewpoints, but more in the way of an inter-feeling, a practice of life engagement. This affectively-oriented approach provides both promise and challenge to the field of phenomenology. It invites us to delve more deeply into feeling acts of seeing. It also helps us understand how, through attending more fully to acts of seeing, we can increase the intensity with which we feel the upsurge of life.
