Research ArticleOpen accessIn the abstractDynamic Stress Analysis of the Arterial Wall Utilizing Physiological Pressure WaveformsM.M. Khani, M. Tafazzoli-Shadpour, S. Delavarpour et al.Arterial diseases, promoted by alterations in arterial wall properties, are among the main causes of mortality. Mechanical stresses of the arterial wall caused by pulsatile luminal pressure define arterial function in normal and pathological conditions. This study aims to determine dynamic stress distribution in the arterial wall subjected to physiological pressure waveforms. Finite element models of a typical artery are … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,167 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMorphological Aspects of the Inferior Frontal Gyrus and its Relations with Brain Hemispheres and Gender: A Study with in vivo Magnetic Resonance ImagingSergio Murilo Georgeto, Munir Antônio Gariba, Luiz Roberto AguiarThis study aims to evaluate the reliability of an anatomy-topographic location method for the anatomical references that form the inferior frontal gyrus and compare the findings of both studied brain hemisphere as well as the genre. Two different pulse sequences-gradient-echo T1 (T1 GRE) and reversal recovery gradient-echo T1 (T1 IR GRE) were used for such purpose. The sample consisted of … …Neuroscience International, Vol. 7, Issue 1 · 22 Mar 2017 · 7,277 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPerformance Evaluation of Multi-Pulse Based Code Excited Linear Predictive Speech Coder with Bitrate Scalable Tool over Additive White Gaussian Noise and Rayleigh Fading ChannelsSuphattharachai ChomphanProblem statement: In the modern speech communication technology, the speech coding with bitrate scalability was needed. However, various types of noises in the communication channels cause damages in the transmitted information especially speech data. Tonal-language speech was also affected by this situation. Approach: Based on the high pitch delay resolution technique, the MPCELP speech coding was proposed over the environment … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,090 accessesView PDF Cite
