Vector quantization (VQ) is a block coding method that famous for its high compression ratio and simple encoder decoder implementation. Linde-Buzo-Gray (LBG) renowned technique VQ uses clustering-based approach finding the optimum codebook. Numerous algorithms, such as Particle Swarm Optimization (PSO), Cuckoo search algorithm (CS), bat algorithm, firefly (FA), are used codebook design. These algorithms primarily focused on improving image quality in terms of PSNR SSIM but use exhaustive...
High security and high reliability identification methods are desired in UAV swarms. An method for unmanned aerial vehicles (UAVs) based on optical spectrum modulation is proposed by using narrow-linewidth CdSe/ZnS quantum dots. By generating an environmental-information-based key-generation algorithm, <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> capable to promptly produce a key spectrum, which conceals its identity codes of . When...
In this paper, we propose an improved methodology for the reduction of mutual coupling within millimeter-wave (mm-wave) wearable multiple-input and multiple-output (MIMO) antennas. Such approach is crucial high frequency applications. The important parameters such as return loss (with hest matching having Sii <; -18 dB with 35 GHz centered frequency), radiation pattern, diversity gain (DG 7 9.99),achieve a reduced even less than -36 it works high-frequency range, which its beauty.
The ever growing space between the high-speed processor and slower main memory has always remained a performance bottleneck. Attempts have been made to address this challenge through advent of smarter memories, an improved hierarchy, deployment high speed bus controllers. Another important dimension is add cache units in order benefit from temporal spatial, even instruction locality therefore, reduce processormemory gap that ultimately results boost. In paper, we demonstrate increasing size...
This paper proposes a novel fast mutation detection system that looks for mutations in the tumor suppressor gene, also known as TP53. Mutations are modifications nucleotide sequences of human genome and may be caused by various factors, such exposure to radiation, sunlight, smoking replication errors. TP53 most common cause cancer early prevent from happening. The proposed utilizes high matching speed logic-based content-addressable memory (CAM) along with hamming distance calculator...
Ternary content-addressable memory (TCAM) is famous for its high-speed search operation but this speed comes at the cost of high-power consumption. The paper presents a power efficient architecture TCAM on field-programmable gate array (FPGA) by using segmented matchline (ML) strategy. Each ML divided into four equal segments where each segment has nine bits. proposed implemented Xilinx Virtex-6 FPGA size 64 × 36. Implementation results show that during operation, in 13.88% reduction dynamic...

Bangladesh is currently facing a significant energy crisis, compounded by its limited foreign exchange reserves in the central bank. Despite being classified as lower-middle-income country, nation's electricity generation remains heavily reliant on non-renewable sources. This research seeks to address these pressing challenges advocating for adoption of renewable solutions. In response challenges, tailored hybrid power plant model presented Uttar Char Fasson, an area often marginalized...
Different surface finished lead-free electroplated Cu substrates were prepared using an electrolytic process jointly developed for special applications. The morphology and plated layer thicknesses investigated atomic force microscope (AFM) scanning electron (SEM). From SEM micrographs, it was confirmed that the layers i.e., Au/Ni Ag/Ni well deposited on uniformly. In addition, increased with increasing processing temperature. average p lated atplated temperatures of 30°C, 40°C 5 0°C about...
In this work a microstrip textile antenna using jeans as substrate resonating at 3 GHz has been designed. Jeans is chosen since it extremely flexible and stable dielectric constant over wide frequency range. The performance of the analyzed in terms return loss, voltage standing wave ratio, gain radiation pattern. It found that certain bending condition, operating shifts around 10%. To reduce shift, very thin (0.1mm) polypropylene (PP) sheet used conjunction with substrate. PP comparatively...
