Hospitals and medical centers produce an enormous amount of digital medical images every day, especially in the form of image sequences, which requires considerable storage space. One solution could be the application of lossless compression. Among available methods, JPEG-LS has excellent coding performance. However, it only compresses a single picture with(More)
A cathode for high-rate performance lithium-ion batteries (LIBs) has been developed from a crystal habit-tuned nanoplate Li(Li(0.17)Ni(0.25)Mn(0.58))O₂ material, in which the proportion of (010) nanoplates (see figure) has been significantly increased. The results demonstrate that the fraction of the surface that is electrochemically active for Li(+)(More)
The amount of image data generated by capsule endoscopy is so large that data compression is desirable. In our compression scheme, a codebook (CB) replenishment mechanism is incorporated in a wavelet-based adaptive vector quantizer (VQ). The progressive SPIHT coding is used to meet the quality demand from a user. Furthermore, in our VQ implementation, a(More)
A facile and scalable single-step approach is employed to synthesize a bulk germanium electrode, which consists of nanoscale Ge-grains in ∼5 μm porous powders. This three-dimensional Ge electrode exhibits superior specific capacity (∼1500 mA h g(-1)) and cyclic performance, attributed to its unique lithiation/delithiation processes.
This paper proposes an improved wavelet with approximating function which is symmetric in nature is proposed for compression technique. Multi-application smart cards are fast replacing the conventional cards such as driving license, health insurance card, identity card, credit card with a single card. Thus, the amount of data stored in the smart card is(More)
