Research ArticleOpen accessIn the abstractA NOVEL SPEECH ENHANCEMENT APPROACH BASED ON MODIFIED DCT AND IMPROVED PITCH SYNCHRONOUS ANALYSISV. R. Balaji, S. SubramanianSpeech enhancement has become an essential issue within the field of speech and signal processing, because of the necessity to enhance the performance of voice communication systems in noisy environment. There has been a number of research works being carried out in speech processing but still there is always room for improvement. The main aim is to enhance the apparent … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 21 Nov 2013 · 6,796 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Link Dimensions on D Type Eccentric Steel FramesMazen Ali MusmarIn seismic prone regions, buildings are designed to maintain sufficient stiffness during moderate earthquakes and to absorb and dissipate a large amount of the energy released due to severe earthquakes. The usual steel framing systems; the moment frames require larger member sections to satisfy stiffness requirements and have large ductility capacity, the concentrically braced frames satisfy stiffness on the expense … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 12 Feb 2013 · 7,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach to Damage Detection in Composite Body Structures Using Time Compensated Hyperspectral Image Analysis TechniqueMahmoud Zaki IskandaraniA novel approach to damage detection in composite car body structures using hyperspectral image index analysis algorithm is presented and discussed. The adapted technique allows the monitoring and analysis of a components structure based on correlation between time spaced thermal images. The technique produces several organized tables resulting from image fusion and frame deviation pixel redistribution calculations, which results in … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 1 Feb 2013 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch Analysis of UkuleleSuphattharachai ChomphanProblem statement: The ukulele is a trendy instrument in the present day. It is a member of the guitar family of instruments which employs four nylon or gut strings or four courses of strings. However, a statistical analysis of the pitch of this instrument has not been conducted. To analysis pitch or fundamental frequency of its main cords should be … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractElastic-Plastic Non Linear Behaviors of Suddenly Loaded StructuresAssal Tehseen HusseinProblem statement: The adaptively shifted integration technique was applied to the elasticplastic analysis of framed structures under dynamic loading. Approach: This study used analysis of linear beam element, the reshifting of the of the integration points in the element is conducted in order to attain higher accuracy. Results: In nonlinear finite element analysis by the ASI technique, the highest computational … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Signaling and Distributive Efficiency of Judicial DecisionsEdmund H. MantellProblem statement: This study considered the problem of how a judge can render an optimal decision in a lawsuit where two litigants each assert a property right in a case where the relevant information is asymmetrically distributed between the parties and the judicial decision-maker. Approach: The research embodied in this study defines an optimal decision as one reflecting the distributive … …Journal of Social Sciences, Vol. 6, Issue 2 · 30 Jun 2010 · 8,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractProsody Modification of Standard Arabic Speech Using Combining Synchronous Overlap and Add With Fixed-Synthesis Algorithm and Multi Level Discrete Wavelet TransformYkhlef Faycal, Bensebti Mesaoud, Bendaouia LotfiProblem statement: The objective of prosody modification is to change the amplitude, duration and pitch (F0) of speech segments without altering their spectral envelop. Applications are numerous, including, Text-To-Speech synthesis, transformation of voice characteristics and foreign language learning. Several approaches have been developed in the literature to achieve this goal. The main restrictions of these latter are in the modification … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeismic Response Evaluation of Moment Resistant Frame with Built-Up Column SectionMohammad Ebrahimi, Hesam Sharifian, Mohammad AhangarProblem statement: Moment Resisting Frame (MRF) is widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Response of these structures is strictly dependent upon behavior of their joints, whereas the analysis of steel moment resisting frames generally has been performed without considering the accurate connection behavior. Approach: In this study Finite Element (FE) models … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Eigenstructure Assignment for a Static Synchronous CompensatorAhmad N. Al-HusbanProblem statement: Power flow through an AC transmission line is influenced by three basic electrical parameters, which are line impedance, magnitudes and phase-shift angle between the sending and receiving voltages. Therefore, the change in any of the three basic parameters means a change in the power flow through the transmission line. The aims of this research paper are: increase the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractFraming Contests in Environmental Decision-making: A Case Study of the Tar Creek (Oklahoma) Superfund SiteShirley G. Vincent, Thomas E. ShriverProblem statement: Stakeholder involvement processes have become an important component of environmental decision-making. This study investigated the role that stakeholders operating outside of official stakeholder processes may play in influencing the policy environment. An improved understanding of the public and political influences on environmental policy decisions contributes to the development of more effective and legitimate policies. Approach: We utilized frame … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 7,249 accessesView PDFCite
