I then conduct and show some cognitive experiments on SDMSCue to test its cognitive soundness compared to SDM. Small cues refer to input cues that are presented to memory for reading associations; but have many missing parts or fields from them. The original SDM failed to handle such a problem. SDMSCue handles and overcomes this pitfall. The main idea in SDMSCue; is the repeated projection of the semantic space on smaller subspaces; that are selected based on the input cue length and pattern. This process allows for Read/Write operations using an input cue that is missing a large portion. SDMSCue is augmented with the use of genetic algorithms for memory allocation and initialization. I claim that SDM functionality is a subset of SDMSCue functionality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Artificial%20intelligence" title="Artificial intelligence">Artificial intelligence</a>, <a href="https://publications.waset.org/search?q=recall" title=" recall"> recall</a>, <a href="https://publications.waset.org/search?q=recognition" title=" recognition"> recognition</a>, <a href="https://publications.waset.org/search?q=SDM" title=" SDM"> SDM</a>, <a href="https://publications.waset.org/search?q=SDMSCue." title="SDMSCue.">SDMSCue.</a> </p> <a href="https://publications.waset.org/8312/review-and-experiments-on-sdmscue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/8312/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/8312/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/8312/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/8312/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/8312/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/8312/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/8312/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/8312/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/8312/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/8312/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/8312.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">1373</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">76</span> Weight-Based Query Optimization System Using Buffer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kashif%20Irfan">Kashif Irfan</a>, <a href="https://publications.waset.org/search?q=Fahad%20Shahbaz%20Khan"> Fahad Shahbaz Khan</a>, <a href="https://publications.waset.org/search?q=Tehseen%20Zia"> Tehseen Zia</a>, <a href="https://publications.waset.org/search?q=M.%20A.%20Anwar"> M.

We found that the use of Huffman coding reduces the PAR by about 6 dB. Also we have investigated the effect of PAR reduction due to Huffman coding through testing the spectral spreading and the inband distortion due to HPA with different IBO values. We found a complete match of our expectation from the proposed solution with the obtained simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=HPA" title="HPA">HPA</a>, <a href="https://publications.waset.org/search?q=Huffman%20coding" title=" Huffman coding"> Huffman coding</a>, <a href="https://publications.waset.org/search?q=OFDM" title=" OFDM"> OFDM</a>, <a href="https://publications.waset.org/search?q=PAR" title=" PAR"> PAR</a> </p> <a href="https://publications.waset.org/1174/peak-to-average-power-ratio-reduction-in-ofdm-systems-using-huffman-coding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/1174/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/1174/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/1174/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/1174/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/1174/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/1174/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/1174/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/1174/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/1174/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/1174/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/1174.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">2597</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">73</span> Synthesis and Characterization of Chromium (III) Complexes with L-Glutamic Acid, Glycine and LCysteine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kun%20Sri%20Budiasih">Kun Sri Budiasih</a>, <a href="https://publications.waset.org/search?q=Chairil%20Anwar"> Chairil Anwar</a>, <a href="https://publications.waset.org/search?q=Sri%20Juari%20Santosa"> Sri Juari Santosa</a>, <a href="https://publications.waset.org/search?q=Hilda%20Ismail"> Hilda Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some Chromium (III) complexes were synthesized with three amino acids: L Glutamic Acid, Glycine, and L-cysteine as the ligands, in order to provide a new supplement containing Cr(III) for patients with type 2 diabetes mellitus. The complexes have been prepared by refluxing a mixture of Chromium(III) chloride in aqueous solution with L-glutamic acid, Glycine, and L-cysteine after pH adjustment by sodium hydroxide. These complexes were characterized by Infrared and Uv-Vis spectrophotometer and Elemental analyzer. The product yields of four products were 87.50 and 56.76% for Cr-Glu complexes, 46.70% for Cr-Gly complex and 40.08% for Cr-Cys complex respectively.

The model shows very good simulation for S-parameter measurements under different bias conditions. It has been found that this approach can improve the simulation of intrinsic part of the transistor, which is very important for small- and large-signal modeling process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fractional-order%20modeling" title="Fractional-order modeling">Fractional-order modeling</a>, <a href="https://publications.waset.org/search?q=GaN%20HEMT" title=" GaN HEMT"> GaN HEMT</a>, <a href="https://publications.waset.org/search?q=Si-substrate" title=" Si-substrate"> Si-substrate</a>, <a href="https://publications.waset.org/search?q=open%20de-embedding%20structure." title=" open de-embedding structure."> open de-embedding structure.</a> </p> <a href="https://publications.waset.org/10004797/fractional-order-modeling-of-gan-high-electron-mobility-transistors-for-switching-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10004797/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10004797/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10004797/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10004797/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10004797/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10004797/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10004797/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10004797/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10004797/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10004797/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10004797.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">1112</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">71</span> An Ultra-Low Output Impedance Power Amplifier for Tx Array in 7-Tesla Magnetic Resonance Imaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ashraf%20Abuelhaija">Ashraf Abuelhaija</a>, <a href="https://publications.waset.org/search?q=Klaus%20Solbach"> Klaus Solbach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Ultra high-field MRI scanners (3T and higher), parallel RF transmission techniques using multiple RF chains with multiple transmit elements are a promising approach to overcome the high-field MRI challenges in terms of inhomogeneity in the RF magnetic field and SAR.

Two GNN models are constructed to simulate isothermal drain current and power dissipation, respectively. The two model are then composed to simulate the drain current.

We conducted a study to assess financial literacy and financial decision making among Emiratis. Our results show that financial literacy is lacking among Emiratis. Also, almost half of respondents owe loans to other peoples and 1/5 of them have bank loans. We expect that the outcome of this research will be useful for designing educational programs and policies to promote financial planning and security among Emiratis.

HBPAE was prepared through one-pot synthesis between trimethylol propane as a core and AB2 branched monomer which was obtained via Michal addition of methyl methacrylate (MMA) and diethanol amine (DEA). PU was prepared from HBPAE using different ratios of toluene diisocyanate (TDI) to form cured coating film. The prepared HBPAE was characterized using; GPC, FT-IR and 1H-NMR. The mechanical properties (impact, hardness, adhesion, and flexibility), thermal properties (DSC and TGA) and chemical resistance of the applied film were estimated. The results indicated 50% of TDI is the selected ratio. This formulation represents a promising candidate to be used as coating material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Curing" title=" Curing"> Curing</a>, <a href="https://publications.waset.org/search?q=Hyperbranched%20polymer" title=" Hyperbranched polymer"> Hyperbranched polymer</a>, <a href="https://publications.waset.org/search?q=Polyurethane" title=" Polyurethane"> Polyurethane</a>, <a href="https://publications.waset.org/search?q=Urethane-acrylates" title=" Urethane-acrylates"> Urethane-acrylates</a>, <a href="https://publications.waset.org/search?q=water%20borne%20Coatings." title=" water borne Coatings."> water borne Coatings.</a> </p> <a href="https://publications.waset.org/16064/environmental-friendly-polyurethane-coatings-based-on-hyperbranched-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16064/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16064/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16064/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16064/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16064/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16064/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16064/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16064/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16064/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16064/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16064.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">3295</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">63</span> Low cost Nano-membrane Fabrication and Electro-polishing System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ajab%20Khan%20Kasi">Ajab Khan Kasi</a>, <a href="https://publications.waset.org/search?q=Muhammad%20Waseem%20Ashraf"> Muhammad Waseem Ashraf</a>, <a href="https://publications.waset.org/search?q=Jafar%20Khan%20Kasi"> Jafar Khan Kasi</a>, <a href="https://publications.waset.org/search?q=Shahzadi%20Tayyaba"> Shahzadi Tayyaba</a>, <a href="https://publications.waset.org/search?q=NitinAfzulpurkar"> NitinAfzulpurkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents the development of low cost Nano membrane fabrication system. The system is specially designed for anodic aluminum oxide membrane. This system is capable to perform the processes such as anodization and electro-polishing. The designed machine was successfully tested for 'mild anodization' (MA) for 48 hours and 'hard anodization' (HA) for 3 hours at constant 0oC. The system is digitally controlled and guided for temperature maintenance during anodization and electro-polishing. The total cost of the developed machine is 20 times less than the multi-cooling systems available in the market which are generally used for this purpose.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Anodic%20aluminum%20oxide" title="Anodic aluminum oxide">Anodic aluminum oxide</a>, <a href="https://publications.waset.org/search?q=Nano-membrane" title=" Nano-membrane"> Nano-membrane</a>, <a href="https://publications.waset.org/search?q=hardanodization" title=" hardanodization"> hardanodization</a>, <a href="https://publications.waset.org/search?q=mild%20anodization" title=" mild anodization"> mild anodization</a>, <a href="https://publications.waset.org/search?q=electro-polishing." title=" electro-polishing."> electro-polishing.</a> </p> <a href="https://publications.waset.org/6365/low-cost-nano-membrane-fabrication-and-electro-polishing-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6365/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6365/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6365/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6365/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6365/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6365/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6365/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6365/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6365/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6365/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6365.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">2121</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">62</span> A Concept of Successful Collaborative Design towards Sustainability of Project Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yani%20Rahmawati">Yani Rahmawati</a>, <a href="https://publications.waset.org/search?q=Nadjadji%20Anwar"> Nadjadji Anwar</a>, <a href="https://publications.waset.org/search?q=Christiono%20Utomo"> Christiono Utomo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Development in construction industry is leading to involve complexities in engineering systems; whereas it also required to its sustainability towards social, environmental, and economical aspects.

One of proposed solutions by Internet Engineering Task Force (IETF) is to connect the local, multi-hop, and infrastructure-less Mobile Ad hoc Network (MANET) with Internet structure. This connection is done through multi-interface devices known as Internet Gateways. Many issues are related to this connection like gateway discovery, handoff, address auto-configuration and selecting the optimum gateway when multiple gateways exist. Many studies were done proposing gateway selection schemes with a single selection criterion or weighted multiple criteria.

On the basis of aptitude to degrade the crude oil and DCPIP assay, two fungal isolates were selected amongst 15 oil degrading strains. Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54%) and Penicillium commune (48%) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has capability of degradation and can be utilize for cleaning the Saudi Arabian environment.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fungal%20strains" title="Fungal strains">Fungal strains</a>, <a href="https://publications.waset.org/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/search?q=molecular%0D%0Aidentification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/search?q=GC-MS." title=" GC-MS."> GC-MS.</a> </p> <a href="https://publications.waset.org/10003006/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003006/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003006/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003006/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003006/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003006/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003006/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003006/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003006/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003006/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003006/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003006.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">2926</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">58</span> The Effects of Knowledge Management on Human Capital towards Organizational Innovation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Wan%20Norhayate%20Wan%20Daud">Wan Norhayate Wan Daud</a>, <a href="https://publications.waset.org/search?q=Fakhrul%20Anwar%20Zainol"> Fakhrul Anwar Zainol</a>, <a href="https://publications.waset.org/search?q=Maslina%20Mansor"> Maslina Mansor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The study was conducted to produce case studies from the Malaysian public universities stands point East Coast of Malaysia.

The speed of error detection and correction of a code is largely dependent upon the associated encoder and decoder circuits. The complexity and the speed of such circuits are determined by the number of 1?s in the parity check matrix (PCM). The number of 1?s in the parity check matrix for the code proposed by the authors are fewer than in any currently known single error correcting/double error detecting code. This results in simplified encoding and decoding circuitry for error detection and correction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Decoder" title="Decoder">Decoder</a>, <a href="https://publications.waset.org/search?q=Hsiao%20code" title=" Hsiao code"> Hsiao code</a>, <a href="https://publications.waset.org/search?q=Parity%20Check%20Matrix" title=" Parity Check Matrix"> Parity Check Matrix</a>, <a href="https://publications.waset.org/search?q=Syndrome%20Pattern." title=" Syndrome Pattern."> Syndrome Pattern.</a> </p> <a href="https://publications.waset.org/926/decoder-design-for-a-new-single-error-correctingdouble-error-detecting-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/926/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/926/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/926/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/926/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/926/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/926/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/926/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/926/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/926/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/926/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/926.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">2080</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">56</span> Distortion Estimation in Digital Image Watermarking using Genetic Programming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Labiba%20Gilani">Labiba Gilani</a>, <a href="https://publications.waset.org/search?q=Asifullah%20Khan"> Asifullah Khan</a>, <a href="https://publications.waset.org/search?q=Anwar%20M.%20Mirza"> Anwar M.

The distortion is estimated by considering the problem of obtaining a distorted watermarked signal from the original watermarked signal as a function regression problem. This function regression problem is solved using GP, where the original watermarked signal is considered as an independent variable. GP-based distortion estimation scheme is checked for Gaussian attack and Jpeg compression attack. We have used Gaussian attacks of different strengths by changing the standard deviation. JPEG compression attack is also varied by adding various distortions. Experimental results demonstrate that the proposed technique is able to detect the watermark even in the case of strong distortions and is more robust against attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Blind%20Watermarking" title="Blind Watermarking">Blind Watermarking</a>, <a href="https://publications.waset.org/search?q=Genetic%20Programming%20%28GP%29" title=" Genetic Programming (GP)"> Genetic Programming (GP)</a>, <a href="https://publications.waset.org/search?q=Fitness%20Function" title=" Fitness Function"> Fitness Function</a>, <a href="https://publications.waset.org/search?q=Discrete%20Cosine%20Transform%20%28DCT%29." title=" Discrete Cosine Transform (DCT)."> Discrete Cosine Transform (DCT).</a> </p> <a href="https://publications.waset.org/2365/distortion-estimation-in-digital-image-watermarking-using-genetic-programming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2365/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2365/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2365/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2365/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2365/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2365/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2365/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2365/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2365/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2365/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2365.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">1710</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">55</span> Role of Investment in the Course of Economic Growth in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Maqbool%20Hussain%20Sial">Maqbool Hussain Sial</a>, <a href="https://publications.waset.org/search?q=Maaida%20Hussain%20Hashmi"> Maaida Hussain Hashmi</a>, <a href="https://publications.waset.org/search?q=Sofia%20Anwar"> Sofia Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present research was focused to investigate the role of investment in the course of economic growth with reference to Pakistan.

Two sulphur compounds are used as corrosion mediums. Weight loss method was used for measuring the corrosion rate of the carbon steel specimens immersed in technical white oil at 100ºC at various time intervals in absence and presence of the two sulphur compounds. The corroded specimens are examined using the chemical wear test, scratch test and hardness test. The scratch test is carried out using scratch loads from 0.5 Kg to 2.0 Kg. The scratch width is obtained at various scratch load and test conditions. The Brinell hardness test is carried out and investigated for both corroded and inhibited specimens. The results showed that three natural extracts can be used as environmentally friendly corrosion inhibitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Inhibition" title="Inhibition">Inhibition</a>, <a href="https://publications.waset.org/search?q=natural%20extract" title=" natural extract"> natural extract</a>, <a href="https://publications.waset.org/search?q=pipelines%20corrosion" title=" pipelines corrosion"> pipelines corrosion</a>, <a href="https://publications.waset.org/search?q=sulphur%20compounds." title=" sulphur compounds."> sulphur compounds.</a> </p> <a href="https://publications.waset.org/10002283/inhibition-of-pipelines-corrosion-using-natural-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10002283/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10002283/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10002283/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10002283/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10002283/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10002283/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10002283/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10002283/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10002283/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10002283/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10002283.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">2074</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">51</span> Heuristic Search Algorithms for Tuning PUMA 560 Fuzzy PID Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sufian%20Ashraf%20Mazhari">Sufian Ashraf Mazhari</a>, <a href="https://publications.waset.org/search?q=Surendra%20Kumar"> Surendra Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper compares the heuristic Global Search Techniques; Genetic Algorithm, Particle Swarm Optimization, Simulated Annealing, Generalized Pattern Search, genetic algorithm hybridized with Nelder–Mead and Generalized pattern search technique for tuning of fuzzy PID controller for Puma 560. Since the actual control is in joint space ,inverse kinematics is used to generate various joint angles correspoding to desired cartesian space trajectory. Efficient dynamics and kinematics are modeled on Matlab which takes very less simulation time. Performances of all the tuning methods with and without disturbance are compared in terms of ITSE in joint space and ISE in cartesian space for spiral trajectory tracking.

The formulation of the technique under consideration is based on punctual kriging and fuzzy concepts for image restoration in spatial domain. Three different neighbourhood windows are considered to estimate the semivariance at different lags for studying its effect in reduction of negative weights resulted in punctual kriging, consequently restoration of degraded images. Our results show that effect of neighbourhood size higher than 5x5 on reduction in negative weights is insignificant. In addition, image quality measures, such as structure similarity indices, peak signal to noise ratios and the new variogram based quality measures; show that 3x3 window size gives better performance as compared with larger window sizes.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Image%20restoration" title="Image restoration">Image restoration</a>, <a href="https://publications.waset.org/search?q=punctual%20kriging" title=" punctual kriging"> punctual kriging</a>, <a href="https://publications.waset.org/search?q=semi-variance" title=" semi-variance"> semi-variance</a>, <a href="https://publications.waset.org/search?q=structure%20similarity%20index" title=" structure similarity index"> structure similarity index</a>, <a href="https://publications.waset.org/search?q=negative%20weights%20in%20punctual%20kriging." title=" negative weights in punctual kriging."> negative weights in punctual kriging.</a> </p> <a href="https://publications.waset.org/6247/effect-of-neighborhood-size-on-negative-weights-in-punctual-kriging-based-image-restoration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6247/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6247/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6247/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6247/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6247/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6247/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6247/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6247/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6247/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6247/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6247.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">2356</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">49</span> Modal Propagation Properties of Elliptical Core Optical Fibers Considering Stress-Optic Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=M.%20Shah%20Alam">M.

The stress analysis is carried out and anisotropic refractive index change is calculated using both the conventional plane strain approximation and the generalized plane strain approach. After considering the stress optical effect, the modal analysis of the fiber is performed to obtain the solutions of fundamental and higher order modes. The modal effective index, modal birefringence, group effective index, group birefringence, and dispersion of different modes of the fiber are presented. For propagation properties, it can be seen that the results depend much on the approach of stress analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Birefringence" title="Birefringence">Birefringence</a>, <a href="https://publications.waset.org/search?q=dispersion" title=" dispersion"> dispersion</a>, <a href="https://publications.waset.org/search?q=elliptical%20core%20fiber" title=" elliptical core fiber"> elliptical core fiber</a>, <a href="https://publications.waset.org/search?q=optical%20mode%20analysis" title="optical mode analysis">optical mode analysis</a>, <a href="https://publications.waset.org/search?q=stress-optic%20effect" title=" stress-optic effect"> stress-optic effect</a>, <a href="https://publications.waset.org/search?q=stress%20analysis." title=" stress analysis."> stress analysis.</a> </p> <a href="https://publications.waset.org/4157/modal-propagation-properties-of-elliptical-core-optical-fibers-considering-stress-optic-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4157/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4157/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4157/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4157/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4157/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4157/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4157/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4157/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4157/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4157/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4157.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">2290</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">48</span> Improved Zero Text Watermarking Algorithm against Meaning Preserving Attacks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jalil%20Z.">Jalil Z.</a>, <a href="https://publications.waset.org/search?q=Farooq%20M."> Farooq M.</a>, <a href="https://publications.waset.org/search?q=Zafar%20H."> Zafar H.</a>, <a href="https://publications.waset.org/search?q=Sabir%20M."> Sabir M.</a>, <a href="https://publications.waset.org/search?q=Ashraf%20E."> Ashraf E.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Internet is largely composed of textual contents and a huge volume of digital contents gets floated over the Internet daily. The ease of information sharing and re-production has made it difficult to preserve author-s copyright. Digital watermarking came up as a solution for copyright protection of plain text problem after 1993. In this paper, we propose a zero text watermarking algorithm based on occurrence frequency of non-vowel ASCII characters and words for copyright protection of plain text. The embedding algorithm makes use of frequency non-vowel ASCII characters and words to generate a specialized author key. The extraction algorithm uses this key to extract watermark, hence identify the original copyright owner. Experimental results illustrate the effectiveness of the proposed algorithm on text encountering meaning preserving attacks performed by five independent attackers. <p
