Research ArticleOpen accessIn the keywordsRecent Trends in Ozone and Particle Concentrations in the Sydney (Australia) AirshedMerched Azzi, Hiep DucAn overview is presented of changes in ground level ozone and atmospheric fine particles determined using ambient monitoring data collected at selected locations in Sydney, Australia. After removing seasonally, auto-regressive and moving average dependence from the selected time series, the trend of a selected series was modelled using the fractional long-term dependent component. The selected technique was able to detect … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractFine-Tuned and Optimized Transformer-Based Model for EEG Seizure DetectionPuspanjali Mallik, Ajit Kumar Nayak, Kumar Janardan Patra et al.Epilepsy, a widely recognized neurological disorder, results from irregularities in the transmission of electrical impulses among neurons in the brain. Over the last two decades, significant efforts have been made by researchers and clinicians to develop effective methods for its early detection and management. The electroencephalogram (EEG), a non-invasive tool used to monitor brainwave activity, has become a central device … …Journal of Computer Science, Vol. 21, Issue 11 · 11 Feb 2026 · 1,412 accessesView PDFCite

Research ArticleOpen accessIn the abstractExplosion of the Science Modification of Newtonian Dynamics Via Mach’s Inertia Principle and Generalization in Gravitational Quantum Bound Systems and Finite Range of the Gravity-Carriers, Consistent Merely On the Bosons and the FermionsMohsen LutephyNewtonian gravity is modified here via Mach's inertia principle (inertia fully governed by universe) and it is generalized to gravitationally quantum bound systems, resulting scale invariant fully relational dynamics (mere ordering upon actual objects), answering to rotation curves and velocity dispersions of the galaxies and clusters (large scale quantum bound systems), successful in all dimensions and scales from particle to … …Physics International, Vol. 11, Issue 1 · 10 Aug 2020 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeech Enhancement Based on Adaptive Noise Cancellation and Particle Swarm OptimizationTayseer M.F. Taha, Summrina Kanwal Wajid, Amir HussainSpeech enhancement is used in almost all modern communication systems. This is due to the quality of speech being degraded by environmental interference factors, such as: Acoustic additive noise, acoustic reverberation or white Gaussian noise. This paper, explores the potential of different benchmark optimization techniques for enhancing the speech signal. This is accomplished by fine tuning filter coefficients using a … …Journal of Computer Science, Vol. 15, Issue 5 · 28 May 2019 · 7,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Influence of Dust-Salt Aerosols of the Aral Sea on the Morphological Characteristics of the Tissue of the Epididymis of Rats in the ExperimentAssylgul Suleimen, Bibigul Rakhimova et al.Drying of the Aral Sea is a very significant environmental problem of modern times. Dust particles from the dried seabed are spread over long distances and negatively impact the quality of life of residents in nearby areas. One of the significant problems is the decrease in the fertility of residents of the Aral region, but there is insufficient data about … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 24 Jul 2024 · 4,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractDo Cows Under Subacute Ruminal Acidosis (SARA) Attempt to Self-Medicate?Erin Hendriksen, Ousama AlZahal, Tom C. Wright et al.The objective of this study was to examine feed-sorting behavior of dairy cows in response to a grain challenge that leads to Subacute Ruminal Acidosis (SARA). Sixteen multiparous, rumen-cannulated lactating Holstein cows were used. During the first 49 days of the experiment, all cows received a High-Forage diet (HF; 77:23, F: C; NFC=35). Cows were then transitioned to a High-Grain … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 3 · 2 Sep 2015 · 7,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE ABSENCE OF ANTIMATTER FROM THE UNIVERSE, DARK MATTER, THE FINE STRUCTURE PARAMETER, THE FLUCTUATIONS OF THE COSMIC MICROWAVE BACKGROUND RADIATION AND THE TEMPERATURE DIFFERENCE BETWEEN THE NORTHERN AND SOUTHERN HEMISPHERE OF THE UNIVERSEEmmanuil ManousosThe theory of selfvariations correlates five cosmological observations considered to be unrelated by the physical theories of the previous century. The absence of antimatter from the Universe, the Dark Matter, the slight variation of the fine structure parameter, the temperature fluctuations of the cosmic microwave background radiation and the temperature difference between the northern and southern hemisphere of the Universe … …Physics International, Vol. 5, Issue 1 · 28 Nov 2014 · 8,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Aluminum Alloy-Based Nanocomposites Produced by the Addition of AL-TI5-B1 to the Matrix MeltHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study is an attempt to produce aluminum matrix nanocomposites using a certain aluminum alloy (which its melt has high fluidity) as a matrix material and reinforced with hard and stable fine (nano-sized) precipitates. Therefore, Al-Ti5-B1 master alloy and Al-Si alloy of high silicon content were proposed for preparation of such nanocomposites. Three nanocomposites were prepared by adding Al-Ti5-B1 … …Current Research in Nanotechnology, Vol. 4, Issue 1 · 9 Jan 2014 · 7,123 accessesView PDFCite
