Abstract:

The problem of increasing the efficiency of coding of halftone images in the space of bit planes of differences in pixel values obtained using differential coding (DPCM – Differential pulse-code modulation) is considered. For a compact representation of DPCM pixel values, it is proposed to use a combined compression encoder that implements arithmetic coding and run-length coding. An arithmetic encoder provides high compression ratios, but has high computational complexity and significant encoding overhead. This makes it effective primarily for compressing the mean-value bit-planes of DPCM pixe

Abstract:

Abstract. Geoscientific models and measurements generate false precision (scientifically meaningless data bits) that wastes storage space. False precision can mislead (by implying noise is signal) and be scientifically pointless, especially for measurements. By contrast, lossy compression can be both economical (save space) and heuristic (clarify data limitations) without compromising the scientific integrity of data. Data quantization can thus be appropriate regardless of whether space limitations are a concern. We introduce, implement, and characterize a new lossy compression scheme suitable

Abstract:

Orthogonal frequency division multiplexing OFDM is perhaps the most spectrally efficient, robust transmission technique discovered so far for communication systems, and it also mitigates the problem of multipath environment. Due to its advantages in multipath fading channel e.g. robust against ISI, ICI and some other advantages like best QoS for multiple users, efficient usage of bandwidth it is suggested to be the modulation technique for next generation 4G networks e.g. LTE. But along with all its advantages there are some disadvantages also e.g. High PAPR Peak to Average Power Ratio at the

The harm that underwater noise pollution poses to aquatic ecosystems and the resources that support it are being acknowledged on a worldwide scale.

Abstract:

The problem of not having a reliable communication network has arisen as a result of robustness of the network which emanate to having high bit error rate, congestion and fading. This can be overcome by characterizing a typical broadband data networks, designing a Simulink model of the network of study and use it to study the extent of robustness of data in the network, evaluating the behavior of packets in the channel network, designing an adaptive modulation scheme to improve robustness in the data network, simulating the above using MATLAB Simulink, designing a visual basic model for improv

Abstract:

Drilling fluids, also referred to as drilling muds, play a crucial role in rotary drilling operations by lubricating and cooling the drill bit during oil and gas exploration both onshore and offshore. However, the discharge of these fluids, particularly oil-based drilling fluids (OBF), into marine ecosystems poses significant environmental risks, including the degradation of water quality and harm to aquatic organisms. This study investigated the enhanced biodegradation of OBF in marine water (MW) through bioaugmentation with Pseudomonas aeruginosa strain EB38 and Bacillus safensis strain UIS0

Principal component (PC) analysis has received considerable attention as a technique for the extraction of meteorological signals from hyperspectral infra-red sounders such as the Infrared Atmospheric Sounding Interferometer (IASI) and the Atmospheric Infrared Sounder (AIRS). In addition to achieving substantial bit-volume reductions for dissemination purposes, the technique can also be used to generate reconstructed radiances in which random instrument noise has been reduced.

Although the two porous media had very different porosities (22% vs. 40%), the distributions of pore sizes and aspect ratios were similar. A Cr(III)-acetate-HPAM gel caused comparable oil and water permeability reductions in both porous media. In both cores, the gel reduced permeability to water by a factor 80 to 90 times more than that to oil. However, the distributions of water and oil satu

RUX cannot be administered at full dose in patients with lower PLTs, and it is not known whether the association between SVR and OS persists in such patients.

For high-risk patients, a commonly used first-line therapy is hydroxyurea (HU); however, a subgroup of patients become intolerant of or resistant to HU. The phase 3 RESPONSE trial compared ruxolitinib (RUX) and best available therapy (BAT) in patients with PV who were intolerant of or resistant to HU (modified European LeukemiaNet criteria).
