These terms had an influence on the development of the country in the reign of King Rama V owing to the governance reform, and cultures influenced by the West. Those were passed on until the reign of King Rama VI. The preference was not only for the renovation of architecture and arts based on Thai customs reflecting the prosperity and beauty of handicrafts but also for the acceptance of westernization. The remain of this acceptance includes the concept of such value as gentlemanly behavior like that in Victorian Era of the United Kingdom, and the support of women’s status. Moreover, the wide spread of modernization leads to the movement to change the country’s governance system from absolute monarchy to democracy by a group of people called Rattanakosin Era (R.E.) 130 party. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Art%20and%20culture" title="Art and culture">Art and culture</a>, <a href="https://publications.waset.org/search?q=development%20period" title=" development period"> development period</a>, <a href="https://publications.waset.org/search?q=modernization" title=" modernization"> modernization</a>, <a href="https://publications.waset.org/search?q=King%20Rama%20VI." title=" King Rama VI."> King Rama VI.</a> </p> <a href="https://publications.waset.org/10003717/art-and-culture-in-the-development-period-to-modernization-in-the-reign-of-king-rama-vi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003717/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003717/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003717/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003717/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003717/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003717/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003717/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003717/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003717/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003717/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003717.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">1661</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">46</span> Digital Watermarking Based on Visual Cryptography and Histogram</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=R.%20Rama%20Kishore">R.

A watermarking algorithm is presented to achieve the copy right protection of the owner based on visual cryptography, histogram shape property and entropy. In this, both host image and watermark are preprocessed. Host image is preprocessed by using Butterworth filter, and watermark is with visual cryptography. Applying visual cryptography on water mark generates two shares. One share is used for embedding the watermark, and the other one is used for solving any dispute with the aid of trusted authority. Usage of histogram shape makes the process more robust against geometric and signal processing attacks. The combination of visual cryptography, Butterworth filter, histogram, and entropy can make the algorithm more robust, imperceptible, and copy right protection of the owner.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Butterworth%20filter" title="Butterworth filter">Butterworth filter</a>, <a href="https://publications.waset.org/search?q=digital%20watermarking" title=" digital watermarking"> digital watermarking</a>, <a href="https://publications.waset.org/search?q=histogram" title=" histogram"> histogram</a>, <a href="https://publications.waset.org/search?q=visual%20cryptography." title=" visual cryptography."> visual cryptography.</a> </p> <a href="https://publications.waset.org/10004748/digital-watermarking-based-on-visual-cryptography-and-histogram" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10004748/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10004748/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10004748/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10004748/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10004748/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10004748/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10004748/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10004748/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10004748/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10004748/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10004748.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">1678</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">45</span> The Design Inspired by Phra Maha Chedi of King Rama I-IV at Wat Phra Chetuphon Vimolmangklaram Rajwaramahaviharn</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Taechit%20Cheuypoung">Taechit Cheuypoung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The research will focus on creating pattern designs that are inspired by the pagodas, Phra Maha Chedi of King Rama I-IV, that are located in the temple, Wat Phra Chetuphon Vimolmangklararm Rajwaramahaviharn.

This research methodology which are collect quanlitative data through observation, document, and photograph from key informant of costume in the reign of King Rama IX and from another who related to this field.</p> <p>The formal Thai national costume of the reign of King Bhumibol Adulyadej originated from the visit of His Majesty the King to Europe and America in 1960. Since Thailand had no traditional national costume; Her Majesty the Queen initiated the idea to create formal Thai national costumes. In 1964, Her Majesty the Queen selected 8 styles of formal Thai national costume. Later, Her Majesty the Queen confered another 3 formal Thai national costume for men. There are 8 styles of formal Thai national costume for women: Thai Ruean Ton, Thai Chit Lada, Thai Amarin, Thai Borom Phiman, Thai Siwalia, Thai Chakkri, Thai Dusit, and Thai Chakkraphat. There are 3 styles of formal Thai national costume for men: short-sleeve shirt, long-sleeve shirt, and long-sleeve shirt with breechcloth. The costume is widely used in formal ceremony such as greeting ceremony for official foreign visitors, wedding ceremony, or other auspicious ceremonies. Now a day, they are always used as a bridal gown as well. The formal Thai national costume is valuable art that shows Thai identity and, should be preserved for the next generation.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=The%20formal%20Thai%20national%20costume%20for%20women" title="The formal Thai national costume for women">The formal Thai national costume for women</a>, <a href="https://publications.waset.org/search?q=The%20formal%20Thai%20national%20costume%20for%20men" title=" The formal Thai national costume for men"> The formal Thai national costume for men</a>, <a href="https://publications.waset.org/search?q=His%20Majesty%20King%20Bhumibol%20Adulyadej%20the%20Great%20King%20Rama%20IX" title=" His Majesty King Bhumibol Adulyadej the Great King Rama IX"> His Majesty King Bhumibol Adulyadej the Great King Rama IX</a>, <a href="https://publications.waset.org/search?q=Her%20Majesty%20Queen%20Sirikit%20Queen." title=" Her Majesty Queen Sirikit Queen."> Her Majesty Queen Sirikit Queen.</a> </p> <a href="https://publications.waset.org/9999148/formal-thai-national-costume-in-the-reign-of-king-bhumibol-adulyadej" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999148/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999148/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999148/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999148/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999148/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999148/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999148/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999148/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999148/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999148/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999148.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">4444</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">43</span> Optimized and Secured Digital Watermarking Using Entropy, Chaotic Grid Map and Its Performance Analysis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=R.%20Rama%20Kishore">R.

The methodology used in this work is the combination of entropy and chaotic grid map. The proposed methodology incorporates Discrete Cosine Transform (DCT) on the host image. To improve the imperceptibility of the method, the host image DCT blocks, where the watermark is to be embedded, are further optimized by considering the entropy of the blocks. Chaotic grid is used as a key to reorder the DCT blocks so that it will further increase security while selecting the watermark embedding locations and its sequence. Without a key, one cannot reveal the exact watermark from the watermarked image. The proposed method is implemented on four different images. It is concluded that the proposed method is giving better results in terms of imperceptibility measured through PSNR and found to be above 50. In order to prove the effectiveness of the method, the performance analysis is done after implementing different attacks on the watermarked images. It is found that the methodology is very strong against JPEG compression attack even with the quality parameter up to 15. The experimental results are confirming that the combination of entropy and chaotic grid map method is strong and secured to different image processing attacks.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Digital%20watermarking" title="Digital watermarking">Digital watermarking</a>, <a href="https://publications.waset.org/search?q=discrete%20cosine%20transform" title=" discrete cosine transform"> discrete cosine transform</a>, <a href="https://publications.waset.org/search?q=chaotic%20grid%20map" title=" chaotic grid map"> chaotic grid map</a>, <a href="https://publications.waset.org/search?q=entropy." title=" entropy."> entropy.</a> </p> <a href="https://publications.waset.org/10009102/optimized-and-secured-digital-watermarking-using-entropy-chaotic-grid-map-and-its-performance-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10009102/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10009102/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10009102/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10009102/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10009102/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10009102/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10009102/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10009102/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10009102/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10009102/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10009102.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">719</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">42</span> The Relationship between the Palaces and the Buddhist Temples in Rattanakosin Period: Study on Wat Rajadhivas Vihara</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jaruphan%20Supprung">Jaruphan Supprung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The aims of this research were to study the relationship between the Palaces (the Kings and the Royalty of the Chakri Dynasty) and the Buddhist temples including Wat Rajadhivas Vihara in Rattanakosin Period of Thailand with the purpose of creating knowledge for Thai lifelong learning, especially for Thai youth and children, and to create positive attitude on Nationalism, Buddhism and Monarchy of Thai people. The findings disclosed that the Palaces have had relationships with 33,902 temples, close relationship with 290 royal temples, and closer relationship with the 8 royal temples regarded as the “Temple of King Rama”. Moreover, there are only 16 Royal temples including Wat Rajadhivas Vihara where the Chakri Kings present the annual royal Kathin robes to the monks by themselves.

The method is based on averaging the noisy speech power spectrum using time and frequency dependent smoothing factors. These factors are adjusted based on signal-presence probability in individual frequency bins. Signal presence is determined by computing the ratio of the noisy speech power spectrum to its local minimum, which is updated continuously by averaging past values of the noisy speech power spectra with a look-ahead factor. This method adapts very quickly to highly non-stationary noise environments. The proposed method achieves significant improvements over a system that uses voice activity detector (VAD) in noise estimation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Noise%20estimation" title="Noise estimation">Noise estimation</a>, <a href="https://publications.waset.org/search?q=Non-stationary%20noise" title=" Non-stationary noise"> Non-stationary noise</a>, <a href="https://publications.waset.org/search?q=Speechenhancement." title=" Speechenhancement."> Speechenhancement.</a> </p> <a href="https://publications.waset.org/12790/noise-estimation-for-speech-enhancement-in-non-stationary-environments-a-new-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12790/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12790/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12790/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12790/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12790/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12790/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12790/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12790/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12790/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12790/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12790.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">2341</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">40</span> Social and Cultural Capital in Patthana Soi Ranongklang Community, Dusit District, Bangkok</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Phusit%20Phukamchanoad">Phusit Phukamchanoad</a>, <a href="https://publications.waset.org/search?q=Bua%20Srikos"> Bua Srikos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This research aimed to study the characteristics of a community in the social, economic and cultural context. This research used interviews and surveys of the members in the Patthana Soi Ranongklang community, Dusit District, Bangkok. The results are as follows: In terms of overall conditions and characteristics, the Patthana Soi Ranongklang community is located on the property of the Treasury Department. 50 years ago, the location of this community consisted of paddy fields with limited convenience in terms of transportation. Rama V Road was only a small narrow road accessed only by three-wheelers there were no buses. The majority of community members moved in from Mak Khawan Rangsan Bridge. Thus, most community members were either workers or government officials as they were routers not the owners of the land. Therefore, there were no primary occupations within the 7 acres of this community. The development of the community started in 1981. At present, the community is continuously being developed and modernization is rapidly flowing in. One of the reasons was because the main roads were widened, especially Rama V Road that allows more convenient transportation, leading to heightened citizens’ convenience. In terms of the economy and society, Rama V Road causes the research to find out the development and expansion of change in the conditions of the area and buildings. Some buildings were improved and changed along the time, as well as the development of new facilities that caused the community members to continually become more materialistic. In the community, it has well organized and managed jobs to each part of community members, and areas were improved to allow the new buildings and apartments. The trend of jobs became more varied, in terms of both jobs at home, such as workers, merchandizing and small own businesses, and the community jobs outside, which became much more convenient to car drivers as they got used to the narrow roads inside the community. The location of the community next to Rama V Road also allows assistance from government agencies to reach the community with ease. Moreover, the welfare of the community was well taken care of by the community committee. In terms of education, the research found that there are two schools: Wat Pracharabuedham School and Wat Noi Noppakun School that are providing education within the community. The majority in the community have received Bachelor degrees. In areas of culture, the research found that the culture, traditions and beliefs of people in the community were mainly transferred from the old community: the majorities are Buddhists, so especially beliefs in Buddhism; the main reason for this is because the old community was situated near Wat Makut Kasattriyaram. Therefore, the community members have always had Buddhist temples as the centre of the community. Later years, more citizens moved along culture in and bring traditions and beliefs with them. The community members also took part in building a Dharma hall named Wat Duang Jai which is 72 year old.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Social%20Capital" title="Social Capital">Social Capital</a>, <a href="https://publications.waset.org/search?q=Patthana%20Soi%20Ranongklang%0D%0Acommunity" title=" Patthana Soi Ranongklang community"> Patthana Soi Ranongklang community</a>, <a href="https://publications.waset.org/search?q=Way%20of%20Life." title=" Way of Life."> Way of Life.</a> </p> <a href="https://publications.waset.org/10000883/social-and-cultural-capital-in-patthana-soi-ranongklang-community-dusit-district-bangkok" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000883/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000883/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000883/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000883/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000883/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000883/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000883/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000883/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000883/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000883/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000883.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">2224</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">39</span> Developing of Thai Classical Music Ensemble in Rattanakosin Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Pansak%20Vandee">Pansak Vandee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The research titled “Developing of Thai Classical Music Ensemble in Rattanakosin Period" aimed 1) to study the history of Thai Classical Music Ensemble in Rattanakosin Period and 2) to analyze changing in each period of Rattanakosin Era. This is the historical and documentary research. The data was collected by in-depth interview those musicians, and academic music experts and field study. The focus group discussion was conducted to analyze and conclude the findings. The research found that the history of Thai Classical Music Ensemble in Rattanakosin Period derived from the Ayutthaya period. Thai classical music ensemble consisted of “Wong Pipat", “Wong Mahori", “Wong Kreang Sai". “Wong Kubmai", “Wong Krongkak", “Brass Band", and “Kan Band" which were used to ceremony, ritual, drama, performs and entertainment. Changed of the Thai music in the early Rattanakosin Period were passed from the Ayutthaya Period and the influence of the western civilization. New Band formed in Thai Music were “Orchestra" and “Contemporary Band". The role of Thai music was changed from the ceremonial rituals to entertainment. Development of the Thai music during the reign of King Rama 1 to King Rama 7, was improved from the court. But after the revolution, the musical patronage of the court was maintained by the Government. Thai Classical Music Ensemble were performed to be standard pattern.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Development" title="Development">Development</a>, <a href="https://publications.waset.org/search?q=Rattanakosin%20Period" title=" Rattanakosin Period"> Rattanakosin Period</a>, <a href="https://publications.waset.org/search?q=Thai%20Classical%0D%0AMusic%20Ensemble." title=" Thai Classical Music Ensemble."> Thai Classical Music Ensemble.</a> </p> <a href="https://publications.waset.org/9056/developing-of-thai-classical-music-ensemble-in-rattanakosin-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9056/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9056/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9056/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9056/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9056/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9056/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9056/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9056/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9056/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9056/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9056.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">3006</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">38</span> A Study on Bond Strength of Geopolymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rama%20Seshu%20Doguparti">Rama Seshu Doguparti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the experimental investigation on the bond behavior of geo polymer concrete.

The qualitative data was collected through studying related materials, exploring the area, in-depth interviews with three groups of people: three directly responsible officers who were key informants of the district, twenty foreign tourists and five Thai tourist guides. A content analysis was used to analyze the qualitative data. The two main findings of the study were as follows: 1. The identity of the Amphawa District, Samut Songkram province is the area controlled by Amphawa sub district (submunicipality). The working unit which runs and looks after Amphawa sub district administration is known as the Amphawa mayor. This establishment was built to be a resort for normal people and tourists visiting the Amphawa district near the Maekong River consisting of rest accommodations. Along the river there is a restaurant where food and drinks are served, rich mangrove forests, a learning center, fireflies and cork trees. The Amphawa district was built to honor and commemorate King Rama II and is where the greatest number of fireflies and cork trees can be seen in Thailand from May to October each year. 2. The communication of the identity of Amphawa District, Samut Songkram Province which the researcher could find and design to present in English materials can be summed up in 5 items: 1) The history of the Amphawa District, Samut Songkram province 2) The history of King Rama II Memorial Park 3) The identity of Amphawa Floating Market 4) The Learning center of Ecosystem: Fireflies and Cork Trees 5) How to keep Amphawa District, Samut Songkram Province for sustainable tourism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Foreigner%20tourists" title="Foreigner tourists">Foreigner tourists</a>, <a href="https://publications.waset.org/search?q=signified" title=" signified"> signified</a>, <a href="https://publications.waset.org/search?q=semiotics" title=" semiotics"> semiotics</a>, <a href="https://publications.waset.org/search?q=sustainable%20tourism." title=" sustainable tourism."> sustainable tourism.</a> </p> <a href="https://publications.waset.org/13676/the-design-of-english-materials-to-communication-the-identity-of-amphawa-district-samut-songkram-province-for-sustainable-tourism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13676/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13676/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13676/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13676/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13676/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13676/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13676/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13676/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13676/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13676/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13676.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">1790</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">36</span> Simulation as an Effective Tool for the Comparative Evaluation of Field Oriented Control and Direct Torque Control of Induction Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Y.Srinivasa%20Kishore%20Babu">Y.Srinivasa Kishore Babu</a>, <a href="https://publications.waset.org/search?q=G.Tulasi%20Ram%20Das">G.Tulasi Ram Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents a comparative study of two most popular control strategies for Induction motor (IM) drives: Field-Oriented Control (FOC) and Direct Torque Control (DTC).

This paper is on developing an optimum cascaded system for speech enhancement. This aim is attained without diminishing any relevant speech information and without much computational and time complexity. LMS algorithm, Spectral Subtraction and Kalman filter have been deployed as the main de-noising algorithms in this work. Since these algorithms suffer from respective shortcomings, this work has been undertaken to design cascaded systems in different combinations and the evaluation of such cascades by qualitative (listening) and quantitative (SNR) tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=LMS" title="LMS">LMS</a>, <a href="https://publications.waset.org/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/search?q=Speech%20Enhancement%20and%0ASpectral%20Subtraction." title=" Speech Enhancement and Spectral Subtraction."> Speech Enhancement and Spectral Subtraction.</a> </p> <a href="https://publications.waset.org/15307/optimum-cascaded-design-for-speech-enhancement-using-kalman-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15307/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15307/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15307/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15307/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15307/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15307/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15307/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15307/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15307/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15307/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15307.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">1733</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">34</span> Optimizing the Number of Bits/Stage in 10-Bit, 50Ms/Sec Pipelined A/D Converter Considering Area, Speed, Power and Linearity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=P.%20Prasad%20Rao">P.

These two methods are compared by discussing their ease of implementation and by analyzing the output harmonic spectra of various output voltages (line-to-neutral voltages, and line-to-line voltages) and their total harmonic distortion (THD).

The antenna consists of 2-element patch array. The antenna array is operating at multiple frequency bands. The multiband operation is achieved by use of slots at proper locations at the patch. The array is made reconfigurable by use of two PIN-diodes. The antenna is simulated and measured in four states of diodes i.e. ON-ON, ON-OFF, OFF-ON, and OFF-OFF. In ON-ON state of diodes, the resonant frequencies are 4.62-4.96, 6.50-6.75, 6.90-7.01, 7.34-8.22, 8.89-9.09 GHz. In ON-OFF state of diodes, the measured resonant frequencies are 4.63-4.93, 6.50-6.70 and 7.81-7.91 GHz. In OFF-ON states of diodes the resonant frequencies are 1.24-1.46, 3.40-3.75, 5.07-5.25 and 6.90-7.20 GHz and in the OFF-OFF state of diodes 4.49-4.75 and 5.61-5.98 GHz.

Its function is to transfer the sound waves through the ear canal to provide sufficient stimulus to the fluids of the inner ear. Degradation of the ossicles that transmit these sound waves from the eardrum to the inner ear leads to hearing loss. This problem can be overcome by replacing one or more of these ossicles by middleear prosthesis. Designing such prosthesis requires a comprehensive knowledge of the biomechanics of the middle-ear. There are many finite element modeling approaches developed to understand the biomechanics of the middle ear. The available models in the literature, involve high computation time. In this paper, we propose a simplified model which provides a reasonably accurate result with much less computational time. Simulation results indicate a maximum sound pressure gain of 10 dB at 5500 Hz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Ear" title="Ear">Ear</a>, <a href="https://publications.waset.org/search?q=Ossicles" title=" Ossicles"> Ossicles</a>, <a href="https://publications.waset.org/search?q=COMSOL" title=" COMSOL"> COMSOL</a>, <a href="https://publications.waset.org/search?q=Stapes." title=" Stapes."> Stapes.</a> </p> <a href="https://publications.waset.org/5424/a-simplified-solid-mechanical-and-acoustic-model-for-human-middle-ear" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5424/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5424/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5424/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5424/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5424/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5424/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5424/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5424/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5424/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5424/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5424.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">2678</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">28</span> A Novel Implementation of Application Specific Instruction-set Processor (ASIP) using Verilog</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kamaraju.M">Kamaraju.M</a>, <a href="https://publications.waset.org/search?q=Lal%20Kishore.K"> Lal Kishore.K</a>, <a href="https://publications.waset.org/search?q=Tilak.A.V.N"> Tilak.A.V.N</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The general purpose processors that are used in embedded systems must support constraints like execution time, power consumption, code size and so on.

The designed processor architecture consists of on-chip transmitter and receiver modules along with the processing and controlling units to enable the data transmission and reception on a single die. The data transfer is accomplished with less number of instructions as compared with the general purpose processor. The ASIP core operates at a maximum clock frequency of 1.132GHz with a delay of 0.883ns and consumes 569.63mW power at an operating voltage of 1.2V. The ASIP is implemented in Verilog HDL using the Xilinx platform on Virtex4. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=ASIP" title="ASIP">ASIP</a>, <a href="https://publications.waset.org/search?q=Data%20transfer" title=" Data transfer"> Data transfer</a>, <a href="https://publications.waset.org/search?q=Instruction%20set" title=" Instruction set"> Instruction set</a>, <a href="https://publications.waset.org/search?q=Processor" title=" Processor"> Processor</a> </p> <a href="https://publications.waset.org/13190/a-novel-implementation-of-application-specific-instruction-set-processor-asip-using-verilog" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13190/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13190/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13190/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13190/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13190/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13190/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13190/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13190/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13190/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13190/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13190.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">2068</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">27</span> Solitary Wave Solutions for Burgers-Fisher type Equations with Variable Coefficients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Amit%20Goyal">Amit Goyal</a>, <a href="https://publications.waset.org/search?q=Alka"> Alka</a>, <a href="https://publications.waset.org/search?q=Rama%20Gupta"> Rama Gupta</a>, <a href="https://publications.waset.org/search?q=C.%20Nagaraja%20Kumar"> C.

As a result, most of the supersonic vehicles are widely designed using steady state flow characteristics which may have errors while facing unsteady situations. This study aims to explore the possibility of varying the Mach number of the flow during wind tunnel operation. The nozzle walls are restricted to be inflexible for cooling near the throat due to high stagnation temperature requirement of the flow to simulate the conditions as experienced by the vehicle. Two simple independent mechanisms, rotation and translation of nozzle walls have been analyzed and the nozzle ranges have been optimized to vary the Mach number from Mach 2 to Mach 5 using minimum number of nozzles in the wind tunnel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Method%20of%20characteristics" title="Method of characteristics">Method of characteristics</a>, <a href="https://publications.waset.org/search?q=Nozzle" title=" Nozzle"> Nozzle</a>, <a href="https://publications.waset.org/search?q=supersonic%20wind%20tunnel" title=" supersonic wind tunnel"> supersonic wind tunnel</a>, <a href="https://publications.waset.org/search?q=variable%20Mach%20number." title=" variable Mach number."> variable Mach number.</a> </p> <a href="https://publications.waset.org/10007838/analysis-of-simple-mechanisms-to-continuously-vary-mach-number-in-a-supersonic-wind-tunnel-facility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007838/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007838/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007838/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007838/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007838/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007838/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007838/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007838/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007838/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007838/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007838.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">1031</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">25</span> An Aerodynamic Design and Analysis of Motor Cycle Helmet with Anti-Glare Visor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=V.%20C.%20Sathish%20Gandhi">V.

Helmet can protect the vehicle riders from severe injuries during road accident to certain extent. To design a functional helmet, it is important to analyze the shape of the helmet and visor portion. Hence, an attempt has been made for design and analysis of new helmet by considering the drag pressure and anti-glare visor. The drag pressure resistance presses the helmet against the neck portion of the rider. The shape of an aerodynamic helmet can be able to reduce the drag pressure. The spherical shape and a new aerodynamic shape helmets are designed with help of Pro-E software and the drag pressures were calculated and comparison has been made on the basis of drag pressure.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Helmet" title="Helmet">Helmet</a>, <a href="https://publications.waset.org/search?q=drag%20pressure" title=" drag pressure"> drag pressure</a>, <a href="https://publications.waset.org/search?q=aero-dynamic" title=" aero-dynamic"> aero-dynamic</a>, <a href="https://publications.waset.org/search?q=refractive%20index" title=" refractive index"> refractive index</a>, <a href="https://publications.waset.org/search?q=Pro-E." title=" Pro-E."> Pro-E.</a> </p> <a href="https://publications.waset.org/9997848/an-aerodynamic-design-and-analysis-of-motor-cycle-helmet-with-anti-glare-visor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997848/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997848/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997848/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997848/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997848/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997848/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997848/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997848/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997848/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997848/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997848.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">4966</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">24</span> Studies on Determination of the Optimum Distance Between the Tmotes for Optimum Data Transfer in a Network with WLL Capability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=N%20C%20Santhosh%20Kumar">N C Santhosh Kumar</a>, <a href="https://publications.waset.org/search?q=N%20K%20Kishore"> N K Kishore</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Using mini modules of Tmotes, it is possible to automate a small personal area network. This idea can be extended to large networks too by implementing multi-hop routing. Linking the various Tmotes using Programming languages like Nesc, Java and having transmitter and receiver sections, a network can be monitored. It is foreseen that, depending on the application, a long range at a low data transfer rate or average throughput may be an acceptable trade-off. To reduce the overall costs involved, an optimum number of Tmotes to be used under various conditions (Indoor/Outdoor) is to be deduced. By analyzing the data rates or throughputs at various locations of Tmotes, it is possible to deduce an optimal number of Tmotes for a specific network.

To overcome this problem, replacement of PI controller by an intelligent controller based on fuzzy set theory is proposed. The performance of the intelligent controller has been investigated through digital simulation using MATLAB-SIMULINK package for different operating conditions such as sudden change in reference speed and load torque.

Thus communication in MANET functions properly only if the participating nodes cooperate in routing without any malicious intention. However, some of the nodes may be malicious in their behavior, by indulging in flooding attacks on their neighbors. Some others may act malicious by launching active security attacks like denial of service. This paper addresses few related works done on trust evaluation and establishment in ad hoc networks. Related works on flooding attack prevention are reviewed. A new trust approach based on the extent of friendship between the nodes is proposed which makes the nodes to co-operate and prevent flooding attacks in an ad hoc environment. The performance of the trust algorithm is tested in an ad hoc network implementing the Ad hoc On-demand Distance Vector (AODV) protocol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=AODV" title="AODV">AODV</a>, <a href="https://publications.waset.org/search?q=Flooding" title=" Flooding"> Flooding</a>, <a href="https://publications.waset.org/search?q=MANETs" title=" MANETs"> MANETs</a>, <a href="https://publications.waset.org/search?q=trust%20estimation" title=" trust estimation"> trust estimation</a> </p> <a href="https://publications.waset.org/11400/performance-analysis-of-flooding-attack-prevention-algorithm-in-manets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11400/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11400/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11400/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11400/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11400/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11400/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11400/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11400/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11400/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11400/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11400.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">2386</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">21</span> Effect of Non Uniformity Factors and Assignment Factors on Errors in Charge Simulation Method with Point Charge Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Gururaj%20S%20Punekar">Gururaj S Punekar</a>, <a href="https://publications.waset.org/search?q=N%20K%20Kishore%20Senior"> N K Kishore Senior</a>, <a href="https://publications.waset.org/search?q=H%20S%20Y%20Shastry"> H S Y Shastry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Charge Simulation Method (CSM) is one of the very widely used numerical field computation technique in High Voltage (HV) engineering.

It is shown that the symmetrically placed six-point-charge models can be good enough to set up CSM programs with potential errors less than 0.1% when the field non uniformity factor is greater than 2.64 (field utilization factor less than 52.76%).</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Assignment%20factor" title="Assignment factor">Assignment factor</a>, <a href="https://publications.waset.org/search?q=Charge%20Simulation%20Method" title=" Charge Simulation Method"> Charge Simulation Method</a>, <a href="https://publications.waset.org/search?q=High%20Voltage" title=" High Voltage"> High Voltage</a>, <a href="https://publications.waset.org/search?q=Numerical%20field%20computation" title=" Numerical field computation"> Numerical field computation</a>, <a href="https://publications.waset.org/search?q=Non%20uniformity%20factor" title=" Non uniformity factor"> Non uniformity factor</a>, <a href="https://publications.waset.org/search?q=Simulation%20errors." title=" Simulation errors."> Simulation errors.</a> </p> <a href="https://publications.waset.org/15322/effect-of-non-uniformity-factors-and-assignment-factors-on-errors-in-charge-simulation-method-with-point-charge-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15322/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15322/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15322/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15322/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15322/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15322/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15322/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15322/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15322/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15322/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15322.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">2052</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">20</span> ANN Models for Microstrip Line Synthesis and Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Dr.K.Sri%20Rama%20Krishna">Dr.K.Sri Rama Krishna</a>, <a href="https://publications.waset.org/search?q=J.Lakshmi%20Narayana"> J.Lakshmi Narayana</a>, <a href="https://publications.waset.org/search?q=Dr.L.Pratap%20Reddy"> Dr.L.Pratap Reddy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microstrip lines, widely used for good reason, are broadband in frequency and provide circuits that are compact and light in weight. They are generally economical to produce since they are readily adaptable to hybrid and monolithic integrated circuit (IC) fabrication technologies at RF and microwave frequencies. Although, the existing EM simulation models used for the synthesis and analysis of microstrip lines are reasonably accurate, they are computationally intensive and time consuming. Neural networks recently gained attention as fast and flexible vehicles to microwave modeling, simulation and optimization. After learning and abstracting from microwave data, through a process called training, neural network models are used during microwave design to provide instant answers to the task learned.This paper presents simple and accurate ANN models for the synthesis and analysis of Microstrip lines to more accurately compute the characteristic parameters and the physical dimensions respectively for the required design specifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Neural%20Models" title="Neural Models">Neural Models</a>, <a href="https://publications.waset.org/search?q=Algorithms" title=" Algorithms"> Algorithms</a>, <a href="https://publications.waset.org/search?q=Microstrip%20Lines" title=" Microstrip Lines"> Microstrip Lines</a>, <a href="https://publications.waset.org/search?q=Analysis" title="Analysis">Analysis</a>, <a href="https://publications.waset.org/search?q=Synthesis" title=" Synthesis"> Synthesis</a> </p> <a href="https://publications.waset.org/15045/ann-models-for-microstrip-line-synthesis-and-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15045/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15045/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15045/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15045/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15045/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15045/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15045/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15045/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15045/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15045/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15045.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">2151</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">19</span> Three-Level Converters based Generalized Unified Power Quality Conditioner</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Bahr%20Eldin%20S.%20M">Bahr Eldin S.

One of the converters is connected in shunt with one feeder for mitigation of current harmonics and reactive power compensation, while the other two VSCs are connected in series with the other two feeders to maintain the load voltage sinusoidal and at constant level. A new control scheme based on synchronous reference frame is proposed for series converters.

The motivation behind this research work is to obtain a clean speech signal of higher quality by applying the optimal noise cancellation technique. Real-time adaptive filtering algorithms seem to be the best candidate among all categories of the speech enhancement methods. In this paper, we propose a speech enhancement method based on Recursive Least Squares (RLS) adaptive filter of speech signals. Experiments were performed on noisy data which was prepared by adding AWGN, Babble and Pink noise to clean speech samples at -5dB, 0dB, 5dB and 10dB SNR levels. We then compare the noise cancellation performance of proposed RLS algorithm with existing NLMS algorithm in terms of Mean Squared Error (MSE), Signal to Noise ratio (SNR) and SNR Loss. Based on the performance evaluation, the proposed RLS algorithm was found to be a better optimal noise cancellation technique for speech signals.</p> <p class="card-text"><strong>Keywords:</strong> <a
