The Taylor series method provides a simple way of obtaining an infinite series which converges to the exact solution for initial value problems and this method of solution is somewhat limited for a two point boundary problem since the infinite series has to be truncated to include the boundary conditions. In this paper, the Ying Buzu Shu algorithm is used to solve a two point boundary nonlinear diffusion problem for the fourth and sixth order solution and compare their relative error and rate of convergence to the exact solution.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Ying%20Buzu%20Shu" title="Ying Buzu Shu">Ying Buzu Shu</a>, <a href="https://publications.waset.org/search?q=nonlinear%20boundary%20problem" title=" nonlinear boundary problem"> nonlinear boundary problem</a>, <a href="https://publications.waset.org/search?q=Taylor%20series%20algorithm" title=" Taylor series algorithm"> Taylor series algorithm</a>, <a href="https://publications.waset.org/search?q=infinite%20series." title=" infinite series."> infinite series.</a> </p> <a href="https://publications.waset.org/10012623/solution-of-two-point-nonlinear-boundary-problems-using-taylor-series-approximation-and-the-ying-buzu-shu-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012623/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012623/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012623/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012623/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012623/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012623/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012623/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012623/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012623/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012623/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012623.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">141</span> The Impact of the Type of Diversification of Listed Construction Enterprises in China on Corporation Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yi-Hsin%20Lin">Yi-Hsin Lin</a>, <a href="https://publications.waset.org/search?q=Ying-Ying%20Li"> Ying-Ying Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry is the pillar industry in China, accounting for about 6% of the gross domestic product. Along with changes in the external environment of the construction industry in China, the construction firm faces fierce competition. The paper aims to investigate the relationship between diversified types of construction firm and its performance in China. Based on generalist and specialist strategy in organizational ecology, we think a generalist organization can be applied to an enterprise with diversified developments, while specialist groups are extended to professional enterprises .This study takes advantage of annual financial data of listed construction firm to empirically verify the relationship between diversification and corporation performance establishing a regression equation to econometric analysis. We find that: 1) Specialization can significantly improve the level of profitability of listed construction firms, and there is a significant positive relationship with corporate performance; 2) The level of operating performance of listed construction enterprises which engage in unrelated diversification is higher than those with related diversification; 3) The relationship between state-owned construction firms and corporate performance is negative. The more the year of foundation is, the higher performance will be; however, the more the year of being listed, the lower performance will be. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Diversification" title="Diversification">Diversification</a>, <a href="https://publications.waset.org/search?q=Specialization" title=" Specialization"> Specialization</a>, <a href="https://publications.waset.org/search?q=Construction%20Firm" title=" Construction Firm"> Construction Firm</a>, <a href="https://publications.waset.org/search?q=Performance." title=" Performance."> Performance.</a> </p> <a href="https://publications.waset.org/11384/the-impact-of-the-type-of-diversification-of-listed-construction-enterprises-in-china-on-corporation-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11384/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11384/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11384/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11384/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11384/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11384/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11384/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11384/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11384/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11384/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11384.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1749</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">140</span> Simulation of PM10 Source Apportionment at An Urban Site in Southern Taiwan by a Gaussian Trajectory Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chien-Lung%20Chen">Chien-Lung Chen</a>, <a href="https://publications.waset.org/search?q=Jeng-Lin%20Tsai"> Jeng-Lin Tsai</a>, <a href="https://publications.waset.org/search?q=Feng-Chao%20Chung"> Feng-Chao Chung</a>, <a href="https://publications.waset.org/search?q=Su-Ching%20Kuo"> Su-Ching Kuo</a>, <a href="https://publications.waset.org/search?q=Kuo-Hsin%20Tseng"> Kuo-Hsin Tseng</a>, <a href="https://publications.waset.org/search?q=Pei-Hsuan%20Kuo"> Pei-Hsuan Kuo</a>, <a href="https://publications.waset.org/search?q=Li-Ying%20Hsieh">Li-Ying Hsieh</a>, <a href="https://publications.waset.org/search?q=Ying%20I.%20Tsai"> Ying I.

The correlation coefficient between the observed and the calculated daily PM10 concentrations is 0.5 and the absolute bias of the PM10 concentrations is 24%. The simulated PM10 concentrations matched well with the observed data. Although the emission rate of PM10 was dominated by area sources (58%), the results of source apportionments indicated that the primary sources for PM10 at Nanzih Station were point sources (42%), area sources (20%) and then upwind boundary concentration (14%). The obvious difference of PM10 source apportionment between episode and non-episode days was upwind boundary concentrations which contributed to 20% and 11% PM10 sources, respectively. The gas-particle conversion of secondary aerosol and long range transport played crucial roles on the PM10 contribution to a receptor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=back%20trajectory%20model" title="back trajectory model">back trajectory model</a>, <a href="https://publications.waset.org/search?q=particulate%20matter" title=" particulate matter"> particulate matter</a>, <a href="https://publications.waset.org/search?q=sourceapportionment" title=" sourceapportionment"> sourceapportionment</a> </p> <a href="https://publications.waset.org/11484/simulation-of-pm10-source-apportionment-at-an-urban-site-in-southern-taiwan-by-a-gaussian-trajectory-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11484/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11484/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11484/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11484/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11484/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11484/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11484/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11484/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11484/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11484/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11484.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1598</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Interval Type-2 Fuzzy Vibration Control of an ERF Embedded Smart Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chih-Jer%20Lin">Chih-Jer Lin</a>, <a href="https://publications.waset.org/search?q=Chun-Ying%20Lee"> Chun-Ying Lee</a>, <a href="https://publications.waset.org/search?q=Ying%20Liu"> Ying Liu</a>, <a href="https://publications.waset.org/search?q=Chiang-Ho%20Cheng"> Chiang-Ho Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The main objective of this article is to present the semi-active vibration control using an electro-rheological fluid embedded sandwich structure for a cantilever beam. ER fluid is a smart material, which cause the suspended particles polarize and connect each other to form chain. The stiffness and damping coefficients of the ER fluid can be changed in 10 micro seconds; therefore, ERF is suitable to become the material embedded in the tunable vibration absorber to become a smart absorber. For the ERF smart material embedded structure, the fuzzy control law depends on the experimental expert database and the proposed self-tuning strategy. The electric field is controlled by a CRIO embedded system to implement the real application. This study investigates the different performances using the Type-1 fuzzy and interval Type-2 fuzzy controllers. The Interval type-2 fuzzy control is used to improve the modeling uncertainties for this ERF embedded shock absorber. The self-tuning vibration controllers using Type-1 and Interval Type-2 fuzzy law are implemented to the shock absorber system. Based on the resulting performance, Internal Type-2 fuzzy is better than the traditional Type-1 fuzzy control for this vibration control system.</p> <p> </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Electro-Rheological%20Fluid" title="Electro-Rheological Fluid">Electro-Rheological Fluid</a>, <a href="https://publications.waset.org/search?q=Semi-active%20vibration%20control" title=" Semi-active vibration control"> Semi-active vibration control</a>, <a href="https://publications.waset.org/search?q=shock%20absorber" title=" shock absorber"> shock absorber</a>, <a href="https://publications.waset.org/search?q=type%202%20fuzzy%20control." title=" type 2 fuzzy control.

With aerodynamic concepts, a mathematical model is firstly proposed to describe the dynamics of the quadrotor UAV. Parameters of this model are identified by experiments with Matlab Identify Toolbox. A group of PID controllers are then designed based on the developed model. To verify the developed model and controllers, simulations and experiments for altitude control, position control and trajectory tracking are carried out. The results show that the quadrotor UAV well follows the referenced commands, which clearly demonstrates the effectiveness of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Quadrotor%20UAV" title="Quadrotor UAV">Quadrotor UAV</a>, <a href="https://publications.waset.org/search?q=Modeling" title=" Modeling"> Modeling</a>, <a href="https://publications.waset.org/search?q=Control" title=" Control"> Control</a>, <a href="https://publications.waset.org/search?q=Aerodynamics" title=" Aerodynamics"> Aerodynamics</a>, <a href="https://publications.waset.org/search?q=System%20Identification." title=" System Identification."> System Identification.</a> </p> <a href="https://publications.waset.org/7686/modeling-and-control-of-a-quadrotor-uav-with-aerodynamic-concepts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7686/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7686/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7686/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7686/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7686/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7686/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7686/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7686/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7686/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7686/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7686.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">7121</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Applying Fuzzy Analytic Hierarchy Process for Evaluating Service Quality of Online Auction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chien-Hua%20Wang">Chien-Hua Wang</a>, <a href="https://publications.waset.org/search?q=Meng-Ying%20Chou"> Meng-Ying Chou</a>, <a href="https://publications.waset.org/search?q=Chin-Tzong%20Pang"> Chin-Tzong Pang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper applies fuzzy AHP to evaluate the service quality of online auction. Service quality is a composition of various criteria. Among them many intangible attributes are difficult to measure. This characteristic introduces the obstacles for respondents on reply in the survey. So as to overcome this problem, we invite fuzzy set theory into the measurement of performance and use AHP in obtaining criteria. We found the most concerned dimension of service quality is Transaction Safety Mechanism and the least is Charge Item.

However, along with the benefits brought by network virtualization, it also presents some issues regarding security.

Trust is considered as the key to facilitate knowledge sharing. This research proposes shared values and relational embeddedness as antecedents of interorganizational trust. Survey based on managers in major industrial parks in Taiwan confirm that trust is enforced when organizations develop shared values and formed social relational embeddedness. Trust leads to interorganizational knowledge sharing.

First, it could do more changeovers and thus reduce lot sizes, inventories, and inventory costs. Second, it could produce in excess of demand in the period and build additional inventory that can be used to satisfy future demand increments, thus delaying the purchase of the next machine that is required to meet the growth in demand. In this study we propose an enhanced supply chain planning model with flexible planning capability. In addition, a 3D supply chain planning system is illustrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Supply%20chain" title="Supply chain">Supply chain</a>, <a href="https://publications.waset.org/search?q=capacity%20expansion" title=" capacity expansion"> capacity expansion</a>, <a href="https://publications.waset.org/search?q=inventory%20management" title=" inventory management"> inventory management</a>, <a href="https://publications.waset.org/search?q=planning%20system." title=" planning system."> planning system.</a> </p> <a href="https://publications.waset.org/9693/a-design-of-supply-chain-management-system-with-flexible-planning-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9693/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9693/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9693/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9693/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9693/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9693/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9693/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9693/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9693/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9693/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9693.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1562</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> Why Do People Abandon Mobile Social Games?

Before starting the conference, all the participants establish a common conference key to encrypt/decrypt communicated messages. It enables participants to exchange the secure messages. Nevertheless, in the conference, if there are any malicious participants who may try to upset the key generation process causing other legal participants to obtain a different conference key. In this article, we propose an improved conference key agreement with fault-tolerant capability. The proposed scheme can filter malicious participants at the beginning of the conference to ensure that all participants obtain the same conference key.

The experiments were performed on the temperature interval 513-613 K, liquid hourly space velocity (LHSV) of 0.9-2.1h-1, pressures between 0.1 and 1.0 MPa. The effect of different operation conditions on the dehydration of methanol was investigated in a laboratory scale experiment. A new intrinsic kinetics equation based on the mechanism of Langmuir-Hinshelwood dissociation adsorption was developed for the dehydration reaction by fitting the expressions to the experimental data. An activation energy of 67.21 kJ/mol was obtained for the catalyst with the best performance. Statistic test showed that this new intrinsic kinetics equation was acceptable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=catalyst" title="catalyst">catalyst</a>, <a href="https://publications.waset.org/search?q=dimethyl%20ether" title=" dimethyl ether"> dimethyl ether</a>, <a href="https://publications.waset.org/search?q=intrinsic%20kinetics" title=" intrinsic kinetics"> intrinsic kinetics</a>, <a href="https://publications.waset.org/search?q=methanol" title=" methanol"> methanol</a> </p> <a href="https://publications.waset.org/10636/intrinsic-kinetics-of-methanol-dehydration-over-al2o3-catalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10636/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10636/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10636/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10636/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10636/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10636/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10636/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10636/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10636/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10636/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10636.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4657</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">115</span> The Catalytic Properties of PtSn/Al2O3 for Acetic Acid Hydrogenation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mingchuan%20Zhou">Mingchuan Zhou</a>, <a href="https://publications.waset.org/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Alumina supported platinum and tin catalysts with different loadings of Pt and Sn were prepared and characterized by low temperature N<sub>2</sub> adsorption/desorption, H<sub>2</sub>-temperature programed reduction and CO pulse chemisorption.

The dictionary learning methods are widely used because they are adaptive. In this paper, a new dictionary learning method for audio is proposed. Signals are at first decomposed into different degrees of Intrinsic Mode Functions (IMF) using Empirical Mode Decomposition (EMD) technique. Then these IMFs form a learned dictionary. To reduce the size of the dictionary, the K-means method is applied to the dictionary to generate a K-EMD dictionary. Compared to K-SVD algorithm, the K-EMD dictionary decomposes audio signals into structured components, thus the sparsity of the representation is increased by 34.4% and the SNR of the recovered audio signals is increased by 20.9%.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Dictionary%20Learning" title="Dictionary Learning">Dictionary
