Research ArticleOpen accessPhrase in the titleA Simulation Study of Enhanced Distillation Using Ultrasound Waves for the Separation of Azeotropic MixturesTaha Mahdi, Ammar Emad Al-KawazThe potential of ultrasound waves to enhance distillation system for azeotropic mixture is examined through process flowsheeting using Aspen Plus. Since sonication is not a standard feature in the software library, a mathematical model of the proposed distillation system is developed based on first principles in Aspen Custom Modeler and later exported to Aspen Plus environment for process simulation and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Jan 2018 · 8,411 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleControl of Bubble Formation at the Optical Fiber Tip by Analyzing Ultrasound Acoustic WavesViacheslav Viacheslavovich Kazakov, Vladimir Isaakovich Yusupov, Viktor Nikolaevich Bagratashvili et al.The problems of controlling the processes of generation of acoustic waves and microbubbles at the optical fiber tip of moderate-power surgical lasers with wavelengths of 1.9 µm and 0.97 µm using active and passive acoustic methods are considered. It is shown that microbubbles of various sizes can be detected with an ultrasound method, in which the interaction area is recorded … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,485 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA MODIFIED ADAPTIVE WAVELET SHRINKAGE SPECKLE FILTER FOR ULTRASOUND IMAGESNirmaladevi Periyasamy, Asokan RamasamyThe usage of ultrasound imaging for medical diagnosis is limited due to the presence of speckle noise. In this study Modified Adaptive Wavelet Shrinkage Filter (MAWSF) in the translational invariant domain is proposed for the removal of speckle noise. The adaptive wavelet threshold function removes the fixed bias of soft thresholding. A new inter-scale dependency model is proposed, to perform … …Journal of Computer Science, Vol. 9, Issue 10 · 16 Sep 2013 · 6,539 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffectiveness of Ultrasound on the Destruction of E. coliMohammad H. DehghaniThe aim of this study was to investigate the impact of sonication as a disinfection method for determining the effectiveness of ultrasound waves on the inactivation of E. coli. Ultrasound waves at a frequency of 42 kHz were used to expose aqueous suspension of E. coli. Ultrasound waves display a strong influence on the rate of E. coli disruption in … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Ultrasonication on Milk Fat Globule Size and Inhibition of Salmonella enteritidis GrowthUmiatin Umiatin, Dalia Sukmawati, Taryudi Taryudi et al.One significant effect of ultrasonic treatment is the inactivation of microorganisms. This characteristic causes ultrasound to be widely used in food processing, healthcare devices, and water treatment. Ultrasonication is an innovative technology that holds promise for accelerating processes and producing high-quality products. The ultrasonic process in milk processing includes homogenization and sterilization. Milk homogenization standardizes fat globule size, while sterilization … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 8 May 2026 · 1,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractSPECKLE REDUCTION IN ULTRASOUND IMAGES USING NEIGHSHRINK AND BILATERAL FILTERINGR. Vanithamani, G. UmamaheswariSpeckle is a random multiplicative noise which obscures the perception and extraction of fine details in ultrasound images and speckle reduction is necessary to improve the visual quality of ultrasound images for better diagnosis. This study aims at introducing an algorithm by hybridizing bilateral filter with NeighShrink. The bilateral filter is applied before decomposition and after reconstruction of the image … …Journal of Computer Science, Vol. 10, Issue 4 · 19 Dec 2013 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrotherapeutic Interventions for Tennis Elbow or Lateral Epicondylitis: A Brief Review of the LiteratureLevent Ediz, Mahmut AlpayciLateral Epicondylitis (LE) or tennis elbow is a painful and functionally limiting entity affecting the upper limb and hand. The lack of sufficient understanding regarding its pathophysiology has led to a large number of treatment approaches in physiotherapy practice including electrotherapeutic interventions. In the current review we evaluated recent trials and reviews of electrotherapeutic interventions for LE treatment for evidence … …Physics International, Vol. 3, Issue 2 · 26 Feb 2013 · 7,373 accessesView PDFCite
Research ArticleOpen accessIn the abstractDWT to Classify Automatically the Placental Tissues Development: Neural Network ApproachMohammad Ayache, Mohamad Khalil, Francois TranquartProblem statement: This study proposed an approach for classification of placental tissues development using ultrasound images. Approach: This approach was based to the selection of tissues, feature extraction by discrete wavelet transform and classification by neural network and especially the Multi Layer Perceptron (MLP). Results: The proposed approach was tested for ultrasound placental images; resulting in 95% success rate. Conclusion/Recommendations: … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,997 accessesView PDFCite
