Digital video is becoming increasingly prevalent. Unfortunately, editing video remains difficult for several reasons: it is a time-based medium, it has dual tracks of audio and video, and current tools force users to work at the smallest level of detail. Based on interviews with professional video editors and observations of the use of our own editor, we have developed new interaction technique...

[1] We present observations of a rocket-and-wire triggered lightning flash obtained with high-speed video cameras recording 5400 and 50000 frames per second (frame times 185 ms and 20 ms) with time-synchronized current and electric field measurements. Transient leader channels were observed with precursor current pulses occurring before the development of the sustained upward positive leader th...

[1] High‐speed video images of eight branches of a lightning stepped leader recorded at a frame rate of 300 kiloframes per second (kfps) (3.33 ms exposure) are analyzed, representing the fastest published frame rate measurements of stepped leader stepping by about 1 order of magnitude and the first observations of space stems/leaders associated with stepped leaders. Sixteen occurrences of space...

The neuronal growth cone is a major site of surface membrane dynamics associated with uptake and release of materials, motility, and axon extension. Although intracellular membrane organelles are thought to mediate surface membrane addition and retrieval at the growth cone, membrane events are fleeting and therefore difficult to study directly. In an effort to capture transient interactions bet...

We study spacecraft motion near a binary asteroid by means of theoretical and computational tools from geometric mechanics and dynamical systems. We model the system assuming that one of the asteroids is a rigid body (ellipsoid) and the other a sphere. In particular, we are interested in finding periodic and quasi-periodic orbits for the spacecraft near the asteroid pair that are suitable for o...

We investigate the spectrum of elementary particles and fields arising from the superposition of string configurations weighted according to their entropy in the string phase space. We find that this superposition describes a universe with a physical content phenomenologically compatible with the experimental observations and measurements. Masses and couplings are determined as functions of the...

Observations in the region of the Pribilof Islands and Canyon (PIC) reveal a clockwise circulation around the group of islands and around each of the two largest islands, St. Paul and St. George. Six current meters deployed around St. Paul Island revealed a steady clockwise flow around the island, which was strongest south of the island and weakest to the east. We use a high-resolution tidal mo...

in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

TBD Plenary Speech 2: Mobile Device-to-Device Video Distribution: Theory and Application Speaker: Prof. Liang Zhou, Nanjing University of Posts and Telecommunications, China Time: Monday Morning, September 26, 2016 Location: Tongji Room(通济厅), 3rd Floor, Ramada Xi'an Bell Tower Abstract As the video traffic has dominated the data flow of smartphones, traditional cellular communication faces subs...

We present an alternative video-making framework for children with tools that integrate video capture with movie production. We propose different forms of interaction with physical artifacts to capture storytelling. Play interactions as input to video editing systems assuage the interface complexities of film construction in commercial software. We aim to motivate young users in telling their s...
