Between the Cracks: From Squatting to Tactical Media Art in the Netherlands, 1979–1993
… the Netherlands that is rooted in squatting (<em>kraken </em>in Dutch). The verb <em>kraken </em>literally means “to crack open,” and artists used this technique, over the course of the decade, to carve out autonomous platforms in urban and media space, including illegal pirate radio and TV …

Deep learning framework for solving geoacoustic inversion problems using normal mode theory
… on large synthetic datasets generated using the KRAKEN normal mode acoustic propagation model. By learning the complex mapping from the time series of acoustic pressure to environmental parameters, these networks enable near-instantaneous geoacoustic inversion. Three main contributions are …

Metagenomic investigation of co-infections of Ebola virus disease and Lassa fever patients
… popular metagenomics tools in union, k-mer-based Kraken with reads and BLAST- and LCAbased MEGAN with assembled contiguous sequence. We analyze sequence from 463 febrile and afebrile patients from Sierra Leone before and during the 2014 Ebola virus outbreak. We find that co-infection with malaria …

What We Say When We Mean Goodbye
… this collection, with characters ranging from a Kraken to Amelia Earhart to Texas sisters to college boys to a larger than life woman to a thrill killer to a girl who poses nude for an art class and on. These characters are all, in one way or another, in limbo, this place between happiness and …

A modal analysis of acoustic propagation in the changing Arctic environment
… analyzed using normal mode analysis, through the Kraken normal mode code. A simulated lower duct is introduced in order to isolate only those modes which travel within the lower duct. Propagation through the lower duct is compared to propagation in traditional Arctic sound speed profiles, and for …

Tailoring Artificial Muscles for the Design and Development of Soft Underwater Robots
… long tentacles. Third, an octopus-like robot (Kraken) having a 250 mm size dome, is presented that utilizes a hybrid actuation technology consisting of stepper motors and twisted and coiled polymer fishing line muscles (TCPFL). Kraken is equipped with interchangeable arm configurations that are …

Amplitude fluctuation effects in shallow water acoustic scattering by internal waves
… in the simulated internal wave field with the Kraken normal mode program. Theoretical calculations are also performed using the theory developed in this thesis. Comparisons are made between theory and numerical calculations. The results presented and discussed in this thesis are related to the …

Social critique in the major novels of John Wyndham : civilization's secrets and nature's truths
… four major novels: The Day of the Triffids , The Kraken Wakes , The Chrysalids , and The Midwich Cuckoos . Wyndham has been dismissed by many critics as a writer of "cosy catastrophes", a term coined by Brian Aldiss. This title is meant to suggest that Wyndham's works are critically insignificant, …

Detecting advanced botnets in enterprise networks
… using traces from two DGA-based botnets: Kraken and Conflicker, as well as a one-week DNS trace captured from our university and three traces collected from our research lab. Our results show that BotDigger detects all the Kraken bots and 99.8% of Conficker bots with very low false …

Exploring the Surface Liquid and Lake Regions of Titan with Laboratory Experimentation and Cassini Spacecraft Data
… a 32 month period. GIS analysis of an estuary of Kraken Mare, for synthetic aperture radar (SAR) swaths taken 47 days apart, indicate a transient feature, with implications for short-term dynamic processes.</p> <p>A geological characterization of Ligeia Mare, the second largest sea on Titan, was …

Constraining the average fill densities of Mars' lowlands and fluvial erosion of Titan's polar regions.
… of Titan's polar lakes, including Ligeia Mare, Kraken Mare, and Punga Mare in the north and Ontario Lacus in the south, ranges from 4% to 31% of the initial relief. Additional model simulations show that this amount of fluvial erosion does not render craters invisible at the resolution of …

Single event microkinetic model for steam cracking of hydrocarbons
Stoomkraken van koolwaterstoffen is één van de basisprocessen in de petrochemische industrie. De koolwaterstoffen worden bij hoge temperaturen (1000 à 1150K) onder toevoeging van stoom omgezet tot commercieel interessante producten. Zo worden lichte olefines gevormd zoals ethyleen, propyleen en …
