Besides on-line and off-line visual quality evaluation, how distortion is gauged also plays a determinative role in shaping most algorithms for image and video manipulations, such as enhancement, reconstruction, data hiding, compression, and joint source/channel coding. Visual quality control within an encoder and distortion assessment for decoded signal is particularly of interests due to the ...

We report the experimental observation of the generation of short electrical pulses in a switch line, which is a transmission line periodically loaded with electronic switches. Pulse-width compression was experimentally demonstrated in the test switch line, using discrete Esaki diodes as the switches.

According to the characteristics of the map images, a practical data compression system was introduced in this paper. The main idea of this system is to segment the map image into two images: long-line image and the rest short-line image. For the first one, we use the cubic spline interpolation method to compress it; for the other image, we use arithmetic coding. It is proved by the experiments...

We investigate off-line dictionary oriented approaches to DNA sequence compression, based on the Burrows-Wheeler Transform (BWT). The preponderance of short repeating patterns is an important phenomenon in biological sequences. Here, we propose off-line methods to compress DNA sequences that exploit the different repetition structures inherent in such sequences. Repetition analysis is performed...

GPS devices typically make use of images that are excessively large to be stored as a Bit Map, so the images are always compressed. The widespread compression technique is JPEG; however JPEG has a disadvantage – JPEG assumes that the average color of beginning of each blocks line is commonly similar to the average color of end of its preceding blocks line. Almost always this assumption is wrong...

We present the comparison between theoretical and empirical PL relations in V and I bands for the Large Magellanic Cloud. We found that, within the current intrinsic dispersions, theoretical predictions are in remarkable agreement with observational data. We also discuss the PLC relations in (V,B-V) and (V,V-I) as well as the dependence of distance determinations on uncertainties in colors, in ...

In this paper, we propose a compression method that allows for the efficient storage of large amounts of CAN traffic data, which is needed for the forensic investigations of accidents caused by cyber attacks on vehicles. Compression of recorded CAN traffic also reduces the time (or bandwidth) needed to off-load that data from the vehicle. In addition, our compression method allows analysts to p...

Strawson’s case in favor of panpsychism is at heart an updated version of a venerable form of argument I’ll call the ‘intrinsic nature’ argument. It is an extremely interesting argument which deploys all sorts of high caliber metaphysical weaponry (despite the ‘down home’ appeals to common sense which Strawson frequently makes). The argument is also subtle and intricate. So let’s spend some tim...

This paper proposes the use of reference models to detect emotional prominence in the energy and F0 contours. The proposed framework aims to model the intrinsic variability of these prosodic features. We present a novel approach based on Functional Data Analysis (FDA) to build reference models using a family of energy and F0 contours, which are implemented with lexicon-independent models. The n...
