Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF HIGH EFFICIENCY LOW DENSITY PARITY-CHECK CODE DECODER FOR LOW POWER APPLICATIONSM. Revathy, R. SaravananIn this study, we propose a low power, high efficient Low Density Parity-Check Code (LDPC) Decoder Architecture for error detection and correction applications. LDPC codes have been adopted in latest wireless standards such as satellite and mobile communications since they possess superior error-detecting and correcting capabilities. As technology scales, memory devices become larger and more powerful and low power consumption … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 30 Jan 2014 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Architecture of Maximum Power Point Tracking for Ultra-Low-Power Based Hybrid Energy Harvester in Ubiquitous Devices: A ReviewMichelle Lim Sern Mi, Sawal Hamid Muhammad Ali, Md Shabiul IslamThis research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractBER Performance and Data Throughput of Sinusoidal Template-Based Impulse-Radio Ultra Wideband Receivers for Wireless Body Area NetworksMohamad Abou El-Nasr, Heba ShabanWindowed sinusoidal template-based correlator receivers are good candidates for high-data rate low-power Ultra Wideband (UWB) systems. Their performance approaches the performance of optimal detectors and provides low-power consumption. However, the ultra short pulses of UWB technology makes it sensitive to timing-errors. In this paper, the Bit-Error-Rate (BER) performance and maximum allowable data throughput of Equally-Correlated Pulse Position Modulation (EC-PPM) modulation … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 30 May 2013 · 6,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 accessesView PDFCite

Research ArticleOpen accessIn the abstractImage Pre-Processing Techniques to Improve DBT Classification Accuracy With CNN ResNet-50Qodri Aziz, Slamet Riyadi et al.Digital Breast Tomosynthesis (DBT) is a three-dimensional imaging technology that is meant to determine breast cancer more accurately than regular mammograms. But low contrast and noise can make DBT images less clear, which can make deep learning-based classification less accurate. This study seeks to assess the impact of diverse preprocessing techniques on breast cancer classification outcomes utilizing the ResNet-50 Convolutional … …Journal of Computer Science, Vol. 22, Issue 10 · 21 Oct 2026 · 349 accessesView PDFCite
Review ArticleOpen accessIn the abstractHydroponic Fodder in Broiler Nutrition: Effects on Economics of Production, Environmental Impacts, Productive Indices, and Health StatusChristian Anayo Mbajiorgu, Ifeanyichukwu Princewill Ogbuewu, Monnye MabelebeleThe projected global population of 9.7 billion by 2050 will escalate the demand for animal protein, intensifying food insecurity. Broilers, being highly efficient in converting grains into protein-rich food, are crucial in meeting the ever-increasing demand for animal proteins.
