In various data of network intrusion detection used for classification algorithm's learning, a great deal of noise and outlier data are mixed. In case of a learning performed by using data of high impurities, no matter how the performance of classification algorithm is outstanding, any network intrusion detection model of high performance becomes hard to anticipate. To increase the accuracy of network...
We introduce a new glass tile generation method for simulating Stained Glass using region segmentation algorithm and cubic spline interpolation method. We apply a Mean shift segmentation algorithm to a source image to extract a shape of glass tile. We merge regions by user input and use morphological operation to remove the invalid shape. To make the shape of glass tile, we apply cubic spline interpolation...
The work presented in this paper shows the way to generate colored paper mosaics using computer graphics techniques. Following two tasks need to be done to generate colored paper mosaic. The first one is to generate colored paper tile and the other one is to arrange the tile. Voronoi Diagram and Random Point Displacement have been used in this paper to come up with the shape of the tile. And, energy...
Non-photorealistic rendering technique can be powerful approach to enhance both visual coherence and immersion in immersive media. Especially, painterly rendering is one of Non- photorealistic rendering that seems similar to paintings using 2D or 3D model data and artist's painting is affected by factors such as how he observes objects. In here, we can notice from paintings that painters observe the...
Increasing the level of detail (LOD) in brushstrokes within areas of interest improved the realism of painterly rendering. Using a modified quad-tree, we segmented an image into areas with similar levels of saliency, each of these segments was then used to control the brush strokes during rendering. We could also simulate real oil painting steps based on saliency information. Our method produces results...
Complex permittivity measurements of liquids and living cell suspensions with Finite Ground Coplanar waveguides (FG-CPW) in a SU-8 reservoir are presented. A simple de-embedding method based on ABCD matrices is described. Complex permittivity measurements of reference liquids such as methanol and isopropanol show good agreement with theoretical values. Results on living cell suspensions (human embryonic...
AIN/GaN metal insulator semiconductor field effect transistors (MISFETs) were designed, simulated and fabricated. DC and S-parameter measurements were also performed. Drift-diffusion simulations using DESSIS compared AIN/GaN MISFETs and A32Ga68N/GaN Heterostructure FETs (HFETs) with the same geometries. The simulation results show the advantages of AIN/GaN MISFETs in terms of higher saturation current,...
A 3-16 GHz wideband AlGaN/GaN high electron mobility transistor (HEMT) low noise amplifier (LNA), using balanced configuration with a coplanar waveguide (CPW) Lange coupler, is designed and fabricated. The LNA shows a minimum noise figure of 4 dB with associated gain of 20 dB and gain flatness of +/- 3 dB across the 3-16 GHz frequency range. This balanced GaN LNA is suitable for transceiver front-ends...
