Research ArticleOpen accessEvery word in the titleSignal Pathway Regulation in Mammalian Cells in Wireless Communication EnvironmentShengdong LiTo regulate the signal pathway in mammalian cells in a wireless communication environment, an LED light stimulation system has been designed and constructed. To avoid interference from too many data lines, a wireless communication mode has been employed. In this study, HeLa cells and Drosophila melanogaster cells are used as the research objects. The CRY2/CIBN light genetic element system is … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 24 Nov 2025 · 2,001 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUse of Lazy Wavelet and DCT for Vibration Signal CompressionPierre ELE, Auguste Ndtoungou, Jean Pierre Ngantcha, Aimé Joseph Oyobe OkassaIn this study, we compress and decompress the vibration signals from the functioning of a ball bearing. The methodology used to compress the vibration data in this study is to reduce the size of the data by reducing the spectral redundancy of the samples. We have used the DCT, which is recognized for its representational parsimony and bleaching power. To … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 6,863 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigating QoS and Performance of Received Signal Strength Indicator in Fiber Optics Broadband Data CommunicationOwusu Nyarko-Boateng, Adebayo F. Adekoya, Benjamin A. WeyoriThere has been an unusual drop of Fiber Optics Broadband (FOB) internet speed in certain localities in Ghana which severely affect users’ experience. This phenomenon have had a serious impact on the quality of service of internet delivery. This paper accessed the quality service of FOB wireless signal between the last mile cell site and the FOB wireless Access Point … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 3 Aug 2019 · 7,620 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility of Non-destructive and Portable Determination for Carrot Quality based on Acoustic SignalsWangyou Zhang, Mingjin Cai, Qiwei Guo et al.To discuss the feasibility of non-destructive determination method for carrot quality based on the acoustic signal, Pearson correlations between the acoustic eigenvalues and the main compositions of carrot were performed. It indicated that the water content, polysaccharide content and pectin content of carrot were all significantly (P …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 May 2021 · 6,344 accessesView PDFCite
Research NotesOpen accessEvery word in the titleAn Artificial Design Technique to Optimize Signal PeptideGao Cui-Fang, Wang Sen, Tian Feng-Wei et al.To determine optimal artificial signal peptide candidates for the possibility of creating high levels of secretion of heterologous proteins, substitution and redesign of amino acid sequences in the H-domain of the signal peptide was theoretically attempted. The method was based on comprehensive score matrix and Markov transfer matrix, which can make the artificial sequences maintain the structural characteristics and original … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 3 · 21 Jul 2017 · 8,063 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleSignal Domain in Respiratory Sound Analysis: Methods, Application and Future DevelopmentAchmad Rizal, Risanuri Hidayat, Hanung Adi NugrohoThe development of digital signal processing technology encourages researchers to develop better methods for automatic lungs sound recognition system than the existing ones. Lung sounds were originally assessed manually according to doctor's expertise. Signal processing techniques are intended to reduce subjectivity factor. Signal processing techniques for lung sound recognition are developed by researchers based on their point of view to … …Journal of Computer Science, Vol. 11, Issue 10 · 2 Jan 2016 · 8,840 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHIGH SPEED PROBABILISTIC ADDER FOR SIGNAL PROCESSING SUBSYSTEMSC. G. Ravichandran, S. VenkateshbabuThis study proposes a new high performance and low power adder using new design style called probabilistic is proposed. The design of a probabilistic adder that achieves low power and high speed operation. The delay and power dissipation are reduced by dividing the adder into two parts to reduce the carry chain. This dividing approach reduces active power by minimizing … …Journal of Computer Science, Vol. 10, Issue 5 · 30 Dec 2013 · 6,481 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInverse Discrete Fourier Transform-Discrete Fourier Transform Techniques for Generating and Receiving Spectrally Efficient Frequency Division Multiplexing SignalsSahmed IdarwazehProblem statement: Spectrally Efficient Frequency Division Multiplexing (SEFDM) system promises bandwidth savings by multiplexing overlapped non-orthogonal sub-carriers. However, the loss of orthogonality results in increasing the complexity of generation and detection of the signal. In this work, we propose simple framework for the generation of the SEFDM signal based on the Inverse Discrete Fourier Transform (IDFT). Approach: This study further … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Jul 2012 · 8,310 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign and Implementation of an Efficient Software Communications Architecture Core Framework for a Digital Signal Processors PlatformWael A. Murtada, Mohamed M. Zahra, Magdi Fikri et al.Problem statement: The Software Communications Architecture (SCA) was developed to improve software reuse and interoperability in Software Defined Radios (SDR). There had been performance concerns since its conception. Arguably, the majority of the problems and inefficiencies associated with the SCA can be attributed to the assumption of modular distributed platforms relying on General Purpose Processors (GPPs) to perform all signal … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 7,495 accessesView PDFCite
