\It is my thesis that worthwhile improvements can be made to lossless image compression schemes, by considering the correlations between the spectral, temporal and interview aspects of image data, in extension to the spatial correlations that are traditionally exploited." Images are an important part of today's digital world. However, due to the large quantity of data needed to represent modern...

The computational power of network nodes whether it is a mobile device or a miniaturized computer increases year by year, however the capacity of wireless channels in 4G networks is still falling behind for real-time video transmission. The paper proposes utilizing the computational capacities of mobile devices to detect objects of interest and apply less compression to corresponding regions, w...

This study presents a robust evolutionary computational technique, called multi-expression programming (MEP), to derive a highly nonlinear model for the prediction of compression index of fine-grained soils. The proposed model relates the soil compression index to its liquid limit, plastic limit and void ratio. The experimental database used for developing the models was established upon 108 co...

In this paper, four different nondestructive testing (NDT) methods and static bending tests were done on poplar (Populus ussuriensis Kom.) and birch (Betula platyphylla Suk.) Laminated Veneer Lumber (LVL). The effects of compression ratio on the modulus of elasticity (MOE) and modulus of rupture (MOR) of LVL with vertical load and parallel load were investigated. There were four compression rat...

This paper presents the implementation of Linear Frequency Modulation (LFM) pulse compression technique over acoustic waveguides at frequency range (2kHz--3kHz). The medium used for acoustic chirp propagation is air. Real time pulse compression was carried out over DSP kit (TMS320C6713). The obtained range from the compressed pulse accedes to the actual range of the target (sound source). The s...

AIMS We investigated a new lead extraction tool (Compression Coil; One-Tie, Cook Medical) in an experimental traction force study. METHODS AND RESULTS On 13 pacemaker leads (Setrox JS53, Biotronik) traction force testing was performed under different configurations. The leads were assigned to three groups: (i) traction force testing without central locking stylet support (n = 5), (ii) tractio...

In this work, lossless grayscale image compression methods are compared on a public palmprint image database. The total number of test images was about 7752, with 8 bit rates. The performance using different lossless compression algorithms on the compression ratios when processing palmprint sample data is investigated, in particular, we relate the application of CALIC, JPEGLS,RAR, JPEG2000 (los...

This research introduces a new lossless image compression method by a transform function named a Reversible Low Contrast Mapping (RLCM). This function was successful to be implemented as a reversible watermarking method. This proposed method divides an image into fixed-size blocks and groups the blocks into watermark blocks and host blocks. Furthermore, the watermark blocks are embedded in the ...

conclusions after kyphoplasty, her pain was immediately resolved, vertebral body height was restored to normal, and pain score was reduced from 8 to 1. she was discharged with a normal neurological examination and good general condition, and returned to her normal life. in this case, balloon kyphoplasty resulted in the restoration of the vertebral body height, decrease in pain, and returning to...

Test power and test time have been the major issues for current scenario of VLSI testing. The test data compression is the well known method used to reduce the test time. The don’t care bit filling method can be used for effective test data compression as well as reduction in scan power. In this paper we describe the algorithm for don’t care assignment like MT(Minimum Transition)-fill technique...
