A study into the ageing and dating of blue ball tip inks on paper using in situ visible spectroscopy with chemometrics

This study used reflectance visible spectroscopy with chemometrics as an in situ ink dating approach for forensic document examination.

A “bright blue ball”, “brushed with clouds” or “parched, scorched, and washed away”?

This paper examines President Barack Obama’s use of contrasting metaphors and metaphorical stories to frame the issue of climate change and the associated political controversies in a major policy speech at Georgetown University in 2013. One major theme in the speech contrasted a series of metaphors based on violence and destruction with a series of metaphors based on peace, tranquility, and health, all within an overall framing story about the Apollo 8 astronauts and the picture they took of the Earth from lunar orbit. Another major theme is the contrast between metaphors of passivity or obstruction and metaphors of movement and dynamic activity. Within these two sets of thematic contrasts are more subtle contrasts between metaphors associated with the effects of climate change and metaphors associated with ameliorative actions to counteract climate change. All of these themes are presented in a way that fails to acknowledge — and implicitly discredits — possible alternative frames. This, plus the obstruction / movement contrast, effectively aggravates the frame conflicts that have stymied fruitful discussion of these issues throughout the Obama administration. We close the analysis with some specific recommendations for increasing the potential for empathetic understanding through explicit awareness of the framing effects of language.

Robot Motion Algorithm Based on Interaction with Human

In this paper, we quantitatively analyze weariness and impression that a human senses for a robot when the human interacted with the robot through some movements. A red ball and a blue ball are displayed on a simulation screen. The human moves the red ball with a mouse and the computer moves the blue ball. By using these balls, the impression that the action of the robot gives to the human is examined. We analyze the relationship between robot's interactive characterisrtics and produced impressions about the robot in human-robot-interction experiments by using methods of information theory. The difference of the impression between the simulation and the actual robot is proved by an omni-directional robot.
