Method of Production: First the appropriate supplied data files (150000 data points, 500Hz sampling rate, corresponding to 5 minutes of acquisition) were given headers so that they could be recognised as 16 bit aiff 44.1kHz audio files. A Python routine was written to do this; the purpose of this was to permit using them as audio files with realtime audio rate reading and manipulation of the da...

The problem of estimating the k frequency moment Fk, for any non-negative integral value of k, over a data stream by looking at the items exactly once as they arrive, was considered in a seminal paper by Alon, Matias and Szegedy [1, 2]. They present a sampling based algorithm to estimate Fk where, k ≥ 2, using space Õ(n1−1/k)). Coppersmith and Kumar [7] and [10], using different methods, presen...

We consider a compressive video acquisition system where frame blocks are sensed independently. Varying block sparsity is exploited in the form of individual per-block open-loop sampling rate allocation with minimal system overhead. At the decoder, video frames are reconstructed via sliding-window inter-frame total variation minimization. Experimental results demonstrate that such rate-adaptive...

This article explores streaming across the cultural industries, drawing on 39 interviews with CEO/top-level industry executives working in Norwegian music, film, television, and book industries. We examine two broad questions: What dokey players see as main opportunities challenges of streaming?To what extent do compare learn from other industries when making sense of, seeking solutions to, cha...

While classical Rayleigh streaming, whose circulations are perpendicular to the transducer radiating surfaces, is wellknown, transducer-plane streaming patterns, in which vortices circulate parallel to the surface driving the streaming, have been less widely discussed. Previously, a four-quadrant transducer-plane streaming pattern has been seen experimentally and subsequently investigated throu...

Cytoplasmic streaming in characean algae is thought to be generated by interaction between subcortical actin bundles and endoplasmic myosin. Most of the existing evidence supporting this hypothesis is of a structural rather than functional nature. To obtain evidence bearing on the possible function of actin and myosin in streaming, we used perfusion techniques to introduce a number of contracti...

In this PhD proposal, we consider the setting of large scale distributed systems, in which each node needs to quickly process a huge amount of data received in the form of a stream that may have been tampered with by an adversary. In this situation, several fundamental problems has been raised recently, that concern many domains including machine learning, data mining, databases, information re...
