TeX and graphics : The State of the Problem

Nelson H.F. Beebe
1989 Cahiers GUTenberg  
There are no filled areas, so the common publishing technique of shading text, boxes for emphasis is unavailable.  ...  If TgX had a grey-scale primitive that supplied an intensity for rules (filled rectangles), then it would be simple in these bar charts to draw a white rule covering the legend area, erasing anything already  ...

Web 2D Graphics: State-of-the-Art [article]

David Duce, Ivan Herman, Bob Hopgood
2001 Eurographics State of the Art Reports  
The early browsers for the Web were predominantly aimed at retrieval of textual information.  ...  In January 1993, the Mosaic browser was released by NCSA. The browser was simple to download and, by the Autumn of 1993, was available for X workstations, PCs and the Mac.  ...  The user agent will fill the missing colour areas with a linear or radial interpolation of the colours.  ...

1987 Computer Physics Communications  
It combines the best features and the experience acquired with the existing systems together with the user friendliness now possible on modern workstations.  ...  The advent of personal workstations with their good response time and powerful graphics capabilities is making these systems even more popular. PAW has been designed in that spirit.  ...  Different fonts, area filling, been included into a new version.  ...

The paper concludes with reflections on the current state of this area and future prospects.  ...  For a significant range of applications, image graphics has severe limitations, for example in terms of file size, download time and inability to interact with and modify the graphics client-side.  ...  The inputs to a primitive are either the source image (i.e. produced by previous SVG operations) or the output of another primitive; the output of the last primitive is displayed on the screen.  ...

Group Key Managements in Wireless Sensor Networks [chapter]

Ju-hyung Son, Seung-woo Seo, Seung-woo Seo
2010 Sustainable Wireless Sensor Networks  
A sensor network operating in open environments requires a network-wide group key for confidentiality of exchanged messages between sensor nodes.  ...  The major concern of this group key update procedure will be the multi-hop communication overheads of the rekeying messages due to the energy constraints of sensor nodes.  ...  For the broadcast authenticity, we need new security primitives called broadcast authentication.  ...

Real-time Unsupervised Segmentation of human whole-body motion and its application to humanoid robot acquisition of motion symbols

Wataru Takano, Yoshihiko Nakamura
2016 Robotics and Autonomous Systems  
Each derived motion primitive is classified into an HMM for a motion symbol, and parameters of the HMMs are optimized by using the motion primitives as training data in competitive learning.  ...  However, to determine the motion primitives to use as training data for the HMMs, this framework requires a manual segmentation of human motions.  ...  Acknowledgment This research was partially supported by a Grant-in-Aid for Young Scientists (A) (No. 26700021) from the Japan Society for the Promotion of Science, and by the Strategic Information and  ...

Reducing the Overhead of BCH Codes: New Double Error Correction Codes

Luis-J. Saiz-Adalid, Joaquín Gracia-Morán, Daniel Gil-Tomás, J.-Carlos Baraza-Calvo, Pedro-J. Gil-Vicente
2020 Electronics  
Primitive BCH codes only exist for some word lengths, which do not frequently match those employed in digital systems.  ...  We used a methodology to search parity check matrices, based on error patterns, in order to design the new codes.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.  ...

AHA! an 'Artificial Hippocampal Algorithm' for Episodic Machine Learning [article]

Gideon Kowadlo, Abdelrahman Ahmed, David Rawlinson
2020 arXiv   pre-print
The new knowledge can then be used to distinguish between similar experiences, to generalise between classes, and to selectively consolidate to long-term memory.  ...  The Hippocampus is known to be vital to these abilities. AHA is a biologically-plausible computational model of the Hippocampus.  ...  We also greatly appreciate the insight that Rotem Aharon provided in analysing and improving the dynamics of Hopfield networks.  ...

Sadok Lamine, Michael G. Edwards
2015 Computer Methods in Applied Mechanics and Engineering  
The multidimensional methods reduce crosswind diffusion inherent in standard methods for convective flow approximation in porous media.  ...  Comparison is drawn between the methods.  ...  All water saturation and concentration contours are shown at the same output time 0.5 PVI. A CFL of 0.6 is used for the first order method.  ...

Identifying Key Leakage of Bitcoin Users [chapter]

Michael Brengel, Christian Rossow
2018 Lecture Notes in Computer Science  
Then, we focus on implicit key leakage by exploiting the wrong usage of cryptographic primitives and scan Bitcoin's blockchain for ECDSA nonce reuse.  ...  We systematically outline how an attacker can use duplicate r values to leak nonces and secret keys, which goes beyond the simple case where the same nonce and the same key have been used in conjunction  ...  This work was supported by the European Union's Horizon 2020 research and innovation programme, RAMSES, under grant agreement No. 700326.  ...

Coordination of distributed/parallel multiple-grid domain decomposition [chapter]

C. T. H. Everaars, F. Arbab
1996 Lecture Notes in Computer Science  
A w orkable approach for the solution of many (numerical and non-numerical) problems is domain decomposition.  ...  The multiple-grid domain decomposition method used in this paper is based on adaptive partitioning of the domain and results in highly irregular grids as shown in the examples.  ...  New estimates for the lowest value of z in each of these sub-domains, recursively, narrow this search process further and further into smaller and smaller regions that (hopefully) tend towards the area  ...
