Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which allow the user to add custom shader programs. We present a solution which uses a custom shader combined with post-processing software in order to draw outlines and creases of 3...

Abstarct-Allpass digital lters are major building blocks in many digital lter architectures. In this paper an optimal pipelined architecture for a 2nd order allpass section based on 3-port adaptor is proposed. The architecture has been shown to improve the lter overall performance in term of power-area-speed by 3 times using 1 m CMOS standard cell design and by 5.4 times using custom cells. Giv...

In this paper, we develop a heterogeneous architecture for the reconfigurable functional unit of an extensible processor. To verify the efficiency of our architecture, we applied it to 8 applications of Mibench. The new architecture improves execution time of custom instructions by 20% to 30% on average while supporting more custom instructions. The area and the total wire length are reduced by...

Custom tools for MATLAB supporting analysis and design of nonlinear control systems are introduced in this paper. The paper demonstrates their use to solve sample nonlinear control problems and presents some of the MATLAB algorithms involved. A lot of attention is dedicated to a rather unusual collaboration of Simulink and Symbolic Math Toolbox that was employed in creation of the tools.

Spectral fingerprints (SFs) are unique power spectra signatures of human brain regions interest (ROIs, Keitel & Gross, 2016). SFs allow for accurate ROI identification and can serve as biomarkers differences exhibited by non-neurotypical groups. At present, there no open-source, versatile tools to calculate spectral fingerprints. We have filled this gap creating a modular, highly-configurable M...

A 128-channel digital autocorrelator spectrometer using four 32 channel low power CMOS correlator chips has been built and tested. The CMOS correlator chip uses a 2-bit multiplication algorithm and a full-custom CMOS VLSI design to achieve low DC power consumption. The digital autocorrelator spectrometer has a 20 MHz band width, and the total DC power requirement is 6 Watts.

A new method for 5-axis flank milling of free-form surfaces is proposed. Existing path-planning methods typically use on-market tools whose shape cylindrical or conical, and therefore not well-suited meeting fine tolerances manufacturing benchmark like turbine blades, gears, blisks. In contrast, our optimization-based framework incorporates the tool into optimization cycle looks only paths, but...

Background: High throughput sequencing (HTS) has become one of the primary experimental tools used to extract genomic information from biological samples. Bioinformatics tools are continuously being developed for the analysis of HTS data. Beyond some well-defined core analyses, such as quality control or genomic alignment, the consistent development of custom tools and the representation of seq...
