Research ArticleOpen accessIn the keywordsThe Optimistic Adaptive Modulation Technique for Future Wireless CommunicationKugalur Muthusamy Palaniswamy, Veerappa Gounder PalanisamyThe Future Wireless Communication requires 100 Mbits/s Data rate, streaming audio/video, asymmetric access/multiple access, Adaptive modulation and coding, dynamic packet arrangement, smart antenna adaptation andIPv6 facility to enhance error free communication. Various digital modulation techniques have been taken for simulation and bit error rate is calculated in both MC-CDMA System and OFDMA system. The continuous phase modulation techniques ensures large … …Journal of Computer Science, Vol. 9, Issue 4 · 13 May 2013 · 6,448 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimal Decentralized Spectral Resource Allocation for Orthogonal Frequency Division Multiple Access Downlink of Femto Networks Via Adaptive Gradient Vector Step Size ApproachLamia Benmesbah, Bingo Wing-Kuen Ling, Vikram Chandrasekhar et al.Problem statement: For the Orthogonal Frequency Division Multiple Access (OFDMA) downlink of a femto network, the resource allocation scheme would aim to maximize the Area Spectral Efficiency (ASE) subject to constraints on the radio resources per transmission interval accessible by each femtocell. Approach: An optimal resource allocation scheme for completely decentralized femtocell deployments leads to a nonlinear optimization problem because … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 14 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpeech Enhancement Algorithm Using Sub band Two Step Decision Directed Approach with Adaptive Weighting factor and Noise Masking ThresholdDeepa Dhanaskodi, Shanmugam ArumugamProblem statement: Speech Enhancement plays an important role in any of the speech processing systems like speech recognition, mobile communication, hearing aid. Approach: In this work, human perceptual auditory masking effect is incorporated into the single channel speech enhancement algorithm. The algorithm is based on a criterion by which the audible noise may be masked rather than being attenuated and … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy Scope of Cardiographic Diagnosis of Myxomatous Mitral Valvular Disease and Sinus Arrhythmia in Dogs and CatsIntan Permatasari Hermawan, Hana Cipka Pramuda Wardhani, PalestinMyxomatous Mitral Valvular Disease (MMVD) is the most common cardiac problem in dogs, and sinus arrhythmia in cats is important to early diagnosis. This study aimed to diagnose Myxomatous Mitral Valvular Disease (MMVD) using echocardiography and sinus arrhythmia using electrocardiography in dogs and cats. This study evaluates two dogs, a male mix domestic, and two cats, a male mix domestic, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 27 Mar 2025 · 5,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractFedCarepod: Federated Quantum Transfer Learning Approach in Screening Process for Early Detection of Liver AbnormalitiesK MalaThe liver is the most frequently injured intra-abdominal organ that leads to complications. Visual interpretation depends on the expertise, and this justifies the need for automatic accelerated assistive prediction system. Classical and Quantum machine learning approaches are combined to leverage their benefits, and the feasibility of designing a novel system is explored. This approach successfully ends up with health care … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 2,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDFCite
