The e-commerce transaction processes are made up of a variety of diverse organizations and activities that operate independently but are connected together to complete the transaction (from placing an order to the goods reaching the client). After a negative shopping experience, clients frequently disregard the critical assessment of these businesses and submit their feedback on an all-over basis, which benefits certain enterprises but is tedious for others. In this article, we solely dealt with negative reviews and attempted to distinguish between negative reviews where the e-commerce firm is explicitly blamed by customers for a bad purchasing experience and other negative reviews. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title="e-commerce">e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20shopping" title=" online shopping"> online shopping</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20reviews" title=" customer reviews"> customer reviews</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20behaviour" title=" customer behaviour"> customer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20analytics" title=" text analytics"> text analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=n-grams%20classification" title=" n-grams classification"> n-grams classification</a> </p> <a href="https://publications.waset.org/abstracts/168088/blame-classification-through-n-grams-in-e-commerce-customer-reviews" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168088.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">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">223</span> Optimized Microwave Pretreatment of Rice Straw for Conversion into Lignin Free and High Crystalline Cellulose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ishfaq%20Bhat">Mohd Ishfaq Bhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Navin%20Chandra%20Shahi"> Navin Chandra Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Umesh%20Chandra%20Lohani"> Umesh Chandra Lohani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed to evaluate the effect of microwave application in synergy with the conventional sodium chlorite delignification of rice straw biomass. For the study, Box-Behnken experimental design involving four independent parameters, each with three levels viz. microwave power (480-800 W), irradiation time (4-12 min), bleaching solution concentration (0.4-3.0%), and bleaching time (1-5h) was used. The response was taken in the form of delignification percentage. The optimization of process parameters was done through response surface methodology. The respective optimum parameters of microwave power, irradiation time, bleaching solution concentration, and bleaching time were obtained as 671 W, 8.66 min, 2.67%, and 1h. The delignification percentage achieved at optimum conditions was 93.51%. The spectral, morphological, and x-ray diffraction characteristics of the rice straw powder after delignification showed a complete absence of lignin peaks, deconstruction of lignocellulose complex, and an increase of crystallinity (from 39.8 to 61.6 %). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20biomass" title="lignocellulosic biomass">lignocellulosic biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=delignification" title=" delignification"> delignification</a>, <a href="https://publications.waset.org/abstracts/search?q=microwaves" title=" microwaves"> microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20straw" title=" rice straw"> rice straw</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a> </p> <a href="https://publications.waset.org/abstracts/146950/optimized-microwave-pretreatment-of-rice-straw-for-conversion-into-lignin-free-and-high-crystalline-cellulose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146950.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">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">222</span> The Subcellular Localisation of EhRRP6 and Its Involvement in Pre-Ribosomal RNA Processing in Growth-Stressed Entamoeba histolytica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Singh">S.

Bhattacharya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The eukaryotic exosome complex plays a pivotal role in RNA biogenesis, maturation, surveillance and differential expression of various RNAs in response to varying environmental signals. The exosome is composed of evolutionary conserved nine core subunits and the associated exonucleases Rrp6 and Rrp44. Rrp6p is crucial for the processing of rRNAs, other non-coding RNAs, regulation of polyA tail length and termination of transcription. Rrp6p, a 3’-5’ exonuclease is required for degradation of 5’-external transcribed spacer (ETS) released from the rRNA precursors during the early steps of pre-rRNA processing. In the parasitic protist Entamoeba histolytica in response to growth stress, there occurs the accumulation of unprocessed pre-rRNA and 5’ ETS sub fragment. To understand the processes leading to this accumulation, we looked for Rrp6 and the exosome subunits in E. histolytica, by in silico approaches. Of the nine core exosomal subunits, seven had high percentage of sequence similarity with the yeast and human. The EhRrp6 homolog contained exoribonuclease and HRDC domains like yeast but its N- terminus lacked the PMC2NT domain. EhRrp6 complemented the temperature sensitive phenotype of yeast rrp6Δ cells suggesting conservation of biological activity. We showed 3’-5’ exoribonuclease activity of EhRrp6p with in vitro-synthesized appropriate RNAs substrates. Like the yeast enzyme, EhRrp6p degraded unstructured RNA, but could degrade the stem-loops slowly. Furthermore, immunolocalization revealed that EhRrp6 was nuclear-localized in normal cells but was diminished from nucleus during serum starvation, which could explain the accumulation of 5’ETS during stress. Our study shows functional conservation of EhRrp6p in E.histolytica, an early-branching eukaryote, and will help to understand the evolution of exosomal components and their regulatory function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entamoeba%20histolytica" title="entamoeba histolytica">entamoeba histolytica</a>, <a href="https://publications.waset.org/abstracts/search?q=exosome%20complex" title=" exosome complex"> exosome complex</a>, <a href="https://publications.waset.org/abstracts/search?q=rRNA%20processing" title=" rRNA processing"> rRNA processing</a>, <a href="https://publications.waset.org/abstracts/search?q=Rrp6" title=" Rrp6"> Rrp6</a> </p> <a href="https://publications.waset.org/abstracts/55711/the-subcellular-localisation-of-ehrrp6-and-its-involvement-in-pre-ribosomal-rna-processing-in-growth-stressed-entamoeba-histolytica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55711.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">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">221</span> Comparative Vector Susceptibility for Dengue Virus and Their Co-Infection in A. aegypti and A. albopictus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monika%20Soni">Monika Soni</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandra%20Bhattacharya"> Chandra Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Siraj%20Ahmed%20Ahmed"> Siraj Ahmed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Prafulla%20Dutta"> Prafulla Dutta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dengue is now a globally important arboviral disease. Extensive vector surveillance has already established A.aegypti as a primary vector, but A.albopictus is now accelerating the situation through gradual adaptation to human surroundings. Global destabilization and gradual climatic shift with rising in temperature have significantly expanded the geographic range of these species These versatile vectors also host Chikungunya, Zika, and yellow fever virus. Biggest challenge faced by endemic countries now is upsurge in co-infection reported with multiple serotypes and virus co-circulation. To foster vector control interventions and mitigate disease burden, there is surge for knowledge on vector susceptibility and viral tolerance in response to multiple infections. To address our understanding on transmission dynamics and reproductive fitness, both the vectors were exposed to single and dual combinations of all four dengue serotypes by artificial feeding and followed up to third generation. Artificial feeding observed significant difference in feeding rate for both the species where A.albopictus was poor artificial feeder (35-50%) compared to A.aegypti (95-97%) Robust sequential screening of viral antigen in mosquitoes was followed by Dengue NS1 ELISA, RT-PCR and Quantitative PCR. To observe viral dissemination in different mosquito tissues Indirect immunofluorescence assay was performed. Result showed that both the vectors were infected initially with all dengue(1-4)serotypes and its co-infection (D1 and D2, D1 and D3, D1 and D4, D2 and D4) combinations. In case of DENV-2 there was significant difference in the peak titer observed at 16th day post infection. But when exposed to dual infections A.aegypti supported all combinations of virus where A.albopictus only continued single infections in successive days. There was a significant negative effect on the fecundity and fertility of both the vectors compared to control (PANOVA < 0.001). In case of dengue 2 infected mosquito, fecundity in parent generation was significantly higher (PBonferroni < 0.001) for A.albopicus compare to A.aegypti but there was a complete loss of fecundity from second to third generation for A.albopictus. It was observed that A.aegypti becomes infected with multiple serotypes frequently even at low viral titres compared to A.albopictus. Possible reason for this could be the presence of wolbachia infection in A.albopictus or mosquito innate immune response, small RNA interference etc. Based on the observations it could be anticipated that transovarial transmission may not be an important phenomenon for clinical disease outcome, due to the absence of viral positivity by third generation. Also, Dengue NS1 ELISA can be used for preliminary viral detection in mosquitoes as more than 90% of the samples were found positive compared to RT-PCR and viral load estimation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-infection" title="co-infection">co-infection</a>, <a href="https://publications.waset.org/abstracts/search?q=dengue" title=" dengue"> dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20fitness" title=" reproductive fitness"> reproductive fitness</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20quantification" title=" viral quantification"> viral quantification</a> </p> <a href="https://publications.waset.org/abstracts/86135/comparative-vector-susceptibility-for-dengue-virus-and-their-co-infection-in-a-aegypti-and-a-albopictus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86135.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">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">220</span> Ideal Posture in Regulating Legal Regulations in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M%20Jeffri%20Arlinandes%20Chandra">M Jeffri Arlinandes Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puwaningdyah%20Murti%20Wahyuni"> Puwaningdyah Murti Wahyuni</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Mutiara%20M%20Jeffri%20Arlinandes%20Chandra"> Dewi Mutiara M Jeffri Arlinandes Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puwaningdyah%20Murti%20Wahyuni"> Puwaningdyah Murti Wahyuni</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Mutiara"> Dewi Mutiara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia is a state of the law in accordance with article 1 paragraph 3 of the Constitution of the Republic of Indonesia (1945 Constitution), namely, 'the State of Indonesia is a state of law'. The consequences of the rule of law are making the law as the main commanding officer or making the law as a basis for carrying out an action taken by the state. The types of regulations and procedures for the formation of legislation in Indonesia are contained in Law Number 12 of 2011 concerning the Formation of Legislation. Various attempts were made to make quality regulations both in the formal hierarchy and material hierarchy such as synchronization and harmonization in the formation of laws and regulations so that there is no conflict between equal and hierarchical laws, but the fact is that there are still many conflicting regulations found between one another. This can be seen clearly in the many laws and regulations that were sued to judicial institutions such as the Constitutional Court (MK) and the Supreme Court (MA). Therefore, it is necessary to have a formulation regarding the governance of the formation of laws and regulations so as to minimize the occurrence of lawsuits to the court so that positive law can be realized which can be used today and for the future (ius constituendum). The research method that will be used in this research is a combination of normative research (library research) supported by empirical data from field research so that it can formulate concepts and answer the challenges being faced. First, the structuring of laws and regulations in Indonesia must start from the inventory of laws and regulations, whether they can be classified based on the type of legislation, what are they set about, the year of manufacture, etc. so that they can be clearly traced to the regulations relating to the formation of laws and regulations. Second, the search and revocation/revocation of laws and regulations that do not exist in the state registration system. Third, the periodic evaluation system is carried out at every level of the hierarchy of laws and regulations. These steps will form an ideal model of laws and regulations in Indonesia both in terms of content and material so that the instructions can be codified and clearly inventoried so that they can be accessed by the wider community as a concrete manifestation of the principle that all people know the law (presumptio iures de iure). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=legislation" title="legislation">legislation</a>, <a href="https://publications.waset.org/abstracts/search?q=review" title=" review"> review</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluation" title=" evaluation"> evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=reconstruction" title=" reconstruction"> reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/116950/ideal-posture-in-regulating-legal-regulations-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116950.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">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">219</span> Optimization of Sintering Process with Deteriorating Quality of Iron Ore Fines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chandra%20Shekhar%20Verma">Chandra Shekhar Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Umesh%20Chandra%20Mishra"> Umesh Chandra Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blast Furnace performance mainly depends on the quality of sinter as a major portion of iron-bearing material occupies by it hence its quality w.r.t. Tumbler Index (TI), Reducibility Index (RI) and Reduction Degradation Index (RDI) are the key performance indicators of sinter plant. Now it became very tough to maintain the desired quality with the increasing alumina (Al₂O₃) content in iron fines and study is focused on it. Alumina is a refractory material and required more heat input to fuse thereby affecting the desired sintering temperature, i.e. 1300°C. It goes in between the grain boundaries of the bond and makes it weaker. Sinter strength decreases with increasing alumina content, and weak sinter generates more fines thereby reduces the net sinter production as well as plant productivity. Presence of impurities beyond the acceptable norm: such as LOI, Al₂O₃, MnO, TiO₂, K₂O, Na₂O, Hydrates (Goethite & Limonite), SiO₂, phosphorous and zinc, has led to greater challenges in the thrust areas such as productivity, quality and cost. The ultimate aim of this study is maintaining the sinter strength even with high Al₂O without hampering the plant productivity. This study includes mineralogy test of iron fines to find out the fraction of different phases present in the ore and phase analysis of product sinter to know the distribution of different phases. Corrections were done focusing majorly on varying Al₂O₃/SiO₂ ratio, basicity: B2 (CaO/SiO₂), B3 (CaO+MgO/SiO₂) and B4 (CaO+MgO/SiO₂+Al₂O₃). The concept of Alumina / Silica ratio, B3 & B4 found to be useful. We used to vary MgO, Al₂O₃/SiO₂, B2, B3 and B4 to get the desired sinter strength even at high alumina (4.2 - 4.5%) in sinter. The study concludes with the establishment of B4, and Al₂O₃/SiO₂ ratio in between 1.53-1.60 and 0.63- 0.70 respectively and have achieved tumbler index (Drum Index) 76 plus with the plant productivity of 1.58-1.6 t/m2/hr. at JSPL, Raigarh. Study shows that despite of high alumina in sinter, its physical quality can be controlled by maintaining the above-mentioned parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basicity-2" title="Basicity-2">Basicity-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Basicity-3" title=" Basicity-3"> Basicity-3</a>, <a href="https://publications.waset.org/abstracts/search?q=Basicity-4" title=" Basicity-4"> Basicity-4</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinter" title=" Sinter"> Sinter</a> </p> <a href="https://publications.waset.org/abstracts/85749/optimization-of-sintering-process-with-deteriorating-quality-of-iron-ore-fines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85749.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">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">218</span> DNA Barcoding for Identification of Dengue Vectors from Assam and Arunachal Pradesh: North-Eastern States in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monika%20Soni">Monika Soni</a>, <a href="https://publications.waset.org/abstracts/search?q=Shovonlal%20Bhowmick"> Shovonlal Bhowmick</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandra%20Bhattacharya"> Chandra Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitendra%20Sharma"> Jitendra Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Prafulla%20Dutta"> Prafulla Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jagadish%20Mahanta"> Jagadish Mahanta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aedes aegypti and Aedes albopictus are considered as two major vectors to transmit dengue virus. In North-east India, two states viz. Assam and Arunachal Pradesh are known to be high endemic zone for dengue and Chikungunya viral infection. The taxonomical classification of medically important vectors are important for mapping of actual evolutionary trends and epidemiological studies. However, misidentification of mosquito species in field-collected mosquito specimens could have a negative impact which may affect vector-borne disease control policy. DNA barcoding is a prominent method to record available species, differentiate from new addition and change of population structure. In this study, a combined approach of a morphological and molecular technique of DNA barcoding was adopted to explore sequence variation in mitochondrial cytochrome c oxidase subunit I (COI) gene within dengue vectors. The study has revealed the map distribution of the dengue vector from two states i.e. Assam and Arunachal Pradesh, India. Approximate five hundred mosquito specimens were collected from different parts of two states, and their morphological features were compared with the taxonomic keys. The analysis of detailed taxonomic study revealed identification of two species Aedes aegypti and Aedes albopictus. The species aegypti comprised of 66.6% of the specimen and represented as dominant dengue vector species. The sequences obtained through standard DNA barcoding protocol were compared with public databases, viz. GenBank and BOLD. The sequences of all Aedes albopictus have shown 100% similarity whereas sequence of Aedes aegypti has shown 99.77 - 100% similarity of COI gene with that of different geographically located same species based on BOLD database search. From dengue prevalent different geographical regions fifty-nine sequences were retrieved from NCBI and BOLD databases of the same and related taxa to determine the evolutionary distance model based on the phylogenetic analysis. Neighbor-Joining (NJ) and Maximum Likelihood (ML) phylogenetic tree was constructed in MEGA6.06 software with 1000 bootstrap replicates using Kimura-2-Parameter model. Data were analyzed for sequence divergence and found that intraspecific divergence ranged from 0.0 to 2.0% and interspecific divergence ranged from 11.0 to 12.0%. The transitional and transversional substitutions were tested individually. The sequences were deposited in NCBI: GenBank database. This observation claimed the first DNA barcoding analysis of Aedes mosquitoes from North-eastern states in India and also confirmed the range expansion of two important mosquito species. Overall, this study insight into the molecular ecology of the dengue vectors from North-eastern India which will enhance the understanding to improve the existing entomological surveillance and vector incrimination program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COI" title="COI">COI</a>, <a href="https://publications.waset.org/abstracts/search?q=dengue%20vectors" title=" dengue vectors"> dengue vectors</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20barcoding" title=" DNA barcoding"> DNA barcoding</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=North-east%20India" title=" North-east India"> North-east India</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetics" title=" phylogenetics"> phylogenetics</a> </p> <a href="https://publications.waset.org/abstracts/57513/dna-barcoding-for-identification-of-dengue-vectors-from-assam-and-arunachal-pradesh-north-eastern-states-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57513.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">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">217</span> A Terahertz Sensor and Dynamic Switch Based on a Bilayer Toroidal Metamaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angana%20Bhattacharya">Angana Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Sarkar"> Rakesh Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Gagan%20Kumar"> Gagan Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Toroidal resonances, a new class of electromagnetic excitations, demonstrate exceptional properties as compared to electric and magnetic dipolar resonances. The advantage of narrow linewidth in toroidal resonance is utilized in this proposed work, where a bilayer metamaterial (MM) sensor has been designed in the terahertz frequency regime (THz). A toroidal MM geometry in a single layer is first studied. A second identical MM geometry placed on top of the first layer results in the coupling of toroidal excitations, leading to an increase in the quality factor (Q) of the resonance. The sensing capability of the resonance is studied. Further, the dynamic switching from an 'off' stage to an 'on' stage in the bilayer configuration is explored. The ardent study of such toroidal bilayer MMs could provide significant potential in the development of bio-molecular and chemical sensors, switches, and modulators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toroidal%20resonance" title="toroidal resonance">toroidal resonance</a>, <a href="https://publications.waset.org/abstracts/search?q=bilayer" title=" bilayer"> bilayer</a>, <a href="https://publications.waset.org/abstracts/search?q=metamaterial" title=" metamaterial"> metamaterial</a>, <a href="https://publications.waset.org/abstracts/search?q=terahertz" title=" terahertz"> terahertz</a>, <a href="https://publications.waset.org/abstracts/search?q=sensing" title=" sensing"> sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=switching" title=" switching"> switching</a> </p> <a href="https://publications.waset.org/abstracts/142036/a-terahertz-sensor-and-dynamic-switch-based-on-a-bilayer-toroidal-metamaterial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142036.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">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">216</span> MWCNT/CuFe10Al2O19/Polyanilie Nanocomposite for Microwave Absorbing Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pallab%20Bhattacharya">Pallab Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20K.%20Das"> C.

The recent work is attentive to the preparation of nanocomposite based on acid modified MWCNT, hexagonal shaped magnetic M-type hexaferrite (CuFe10Al2O19) and polyaniline. CuFe10Al2O19 was prepared by a facile chemical co-precipitation method. An in-situ approach was employed for the coating of polyaniline on MWCNT/CuFe10Al2O19 nanocomposite. The final fabrication of this nanocomposite for microwave measurements was done suitably in the matrix of thermoplastic polyurethane with 10% filler content. The nanocomposites showed the maximum reflection loss of -60.2 dB (in X-band) at the thickness of 2.5 mm with a broad absorption range in contrast to the pristine MWCNT and CuFe10Al2O19. Addition of PANI improves the microwave absorption property of the nanocomposites. The thermal stability of the prepared nanocomposites is also very high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20materials" title="magnetic materials">magnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20absorption" title=" microwave absorption"> microwave absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=MWCNT" title=" MWCNT"> MWCNT</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/13923/mwcntcufe10al2o19polyanilie-nanocomposite-for-microwave-absorbing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13923.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">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">215</span> Technology Computer Aided Design Simulation of Space Charge Limited Conduction in Polycrystalline Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunj%20Parikh">Kunj Parikh</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Bhattacharya"> S.

In this report, we have presented the results of TCAD simulation in multi-grain thin films. The work has addressed the inhomogeneity in one dimension, but can easily be extended to two and three dimensions. The effect of grain boundaries has mainly been approximated as barriers located at the junction between two adjacent grains.

The synthesized GO-CS adsorbent was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopes (SEM), transmission electron microscopy (TEM), Raman spectroscopy and thermogravimetric analysis (TGA). The removal of MB was conducted in batch mode. The effect of parameters influencing the adsorption of MB such as pH of the solution, initial MB concentration, shaking speed, contact time and adsorbent dosage were studied. The results showed that the GO-CS composite material has high adsorption capacity of 196 mg/g of MB solution at pH 9.0. Further, the adsorption of MB on GO-CS followed pseudo second order kinetics and equilibrium adsorption data well fitted by the Langmuir isotherm model.

With this IFR calculation, we can then observe COVID-19 death figures in different countries around the world and estimate the number of cases since the onset of the pandemic. There is a large range for estimated COVID-19 infections across different countries. This ranged from 0.659 million infections in Hong Kong to 277 million infections in India. The largest estimated share of the population infected is 63% in Peru and the lowest is 3% in Norway. For younger populations, COVID-19 is most fatal in South America; for older populations, it is most fatal in North America. The Asian regions stand out with significantly lower IFRs in older populations: at 80 years old, COVID-19 is about three times as fatal than in South Asia and about twelve times as fatal than in East Asia. The weighted average for the share of the population infected, the sum of infections divided by the sum of populations across all countries, is 23%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title="epidemiology">epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=seroprevalence" title=" seroprevalence"> seroprevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=covid-19" title=" covid-19"> covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=infection%20fatality%20rate" title=" infection fatality rate"> infection fatality rate</a> </p> <a href="https://publications.waset.org/abstracts/148321/the-number-of-corona-virus-infections-in-2020" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148321.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">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">208</span> Grain and Grain Boundary Behavior of Sm Substituted Barium Titanate Based Ceramics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parveen%20Kumar">Parveen Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20K.%20Juneja"> J.

The dielectric constant and tangent loss was measured as a function of frequency from 100Hz to 1MHz at different temperatures (200-500oC). The electrical behavior was then investigated using complex impedance spectroscopy (CIS) technique. From the CIS study, it has been found that there is a contribution of both grain and grain boundary in the electrical behavior of such ceramics. Grain and grain boundary resistivity and capacitance were calculated at different temperature using CIS technique. The present paper is about the discussion of grain and grain boundary contribution towards the electrical properties of Sm modified BaTiO3 based ceramics at high temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grain" title="grain">grain</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20boundary" title=" grain boundary"> grain boundary</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance" title=" impedance"> impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric" title=" dielectric"> dielectric</a> </p> <a href="https://publications.waset.org/abstracts/80702/grain-and-grain-boundary-behavior-of-sm-substituted-barium-titanate-based-ceramics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80702.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">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">207</span> Acoustic Room Impulse Response Computation with Image Sources and Frequency Dependent Boundary Reflection Coefficients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratik%20Gandhi">Pratik Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kavitha%20Chandra"> Kavitha Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Thompson"> Charles Thompson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A computational model of the acoustic room impulse response between transmitters and receivers located in an enclosed cavity under the influence of frequency-dependent reflection coefficients of the walls is presented.

The chemical extraction processes of this production are delignification, bleaching and hydrolysis. In order to produce NCC, raw rice husk (RRH) was grinded and converted to powder form. Powder rice husk was obtained by sieving and the particles in the 75-710 μm size range was used for experimental work. The production of NCC was conducted into the jacketed glass reactor at 80 ˚C temperature under predetermined experimental conditions. In this work NaOH (4M) solution was used for delignification process. After certain experimental time delignified powder RH was collected from the reactor then washed, bleached and finally hydrolyzed in order to degrade cellulose to nanocrystalline cellulose (NCC). For bleaching and hydrolysis processes NaOCl (20%) and H2SO4 (4M) solutions were used, respectively. The resultant products from hydrolysis was neutralized by buffer solution and analyzed by FTIR, XRD, SEM, AFM and TEM. From the analysis, NCC has been identified successfully and the particle dimension has been confirmed to be in the range of 20-50 nm. From XRD results, the crystallinity of NCC was found to be approximately 45%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocrystalline%20cellulose" title="nanocrystalline cellulose">nanocrystalline cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=NCC" title=" NCC"> NCC</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20husk" title=" rice husk"> rice husk</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20extraction" title=" chemical extraction"> chemical extraction</a> </p> <a href="https://publications.waset.org/abstracts/16238/production-of-nanocrystalline-cellulose-ncc-from-rice-husk-biomass-by-chemical-extraction-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16238.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">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">203</span> Semiconducting Nanostructures Based Organic Pollutant Degradation Using Natural Sunlight for Water Remediation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Gupta">Ankur Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayant%20Raj%20Saurav"> Jayant Raj Saurav</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Bhattacharya"> Shantanu Bhattacharya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work we report an effective water filtration system based on the photo catalytic performance of semiconducting dense nano-brushes under natural sunlight. During thin-film photocatalysis usually performed by a deposited layer of photocatalyst, a stagnant boundary layer is created near the catalyst which adversely affects the rate of adsorption because of diffusional restrictions. One strategy that may be used is to disrupt this laminar boundary layer by creating a super dense nanostructure near the surface of the catalyst. Further it is adequate to fabricate a structured filter element for a through pass of the water with as grown nanostructures coming out of the surface of such an element. So, the dye remediation is performed through solar means. This remediation was initially limited to lower efficiency because of diffusional restrictions but has now turned around as a fast process owing to the development of the filter materials with standing out dense nanostructures. The effect of increased surface area due to microholes on fraction adsorbed is also investigated and found that there is an optimum value of hole diameter for maximum adsorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20materials" title="nano materials">nano materials</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20remediation" title=" water remediation"> water remediation</a> </p> <a href="https://publications.waset.org/abstracts/33109/semiconducting-nanostructures-based-organic-pollutant-degradation-using-natural-sunlight-for-water-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33109.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">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">202</span> Infrastructural Investment and Economic Growth in Indian States: A Panel Data Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonardan%20Koner">Jonardan Koner</a>, <a href="https://publications.waset.org/abstracts/search?q=Basabi%20Bhattacharya"> Basabi Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Purandare"> Avinash Purandare </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study is focused to find out the impact of infrastructural investment on economic development in Indian states.

Billions of users reveal not only their own information (self disclosure) but also information about others (other-generated disclosure), resulting in a risk and a serious threat to either personal or informational privacy. Self-disclosure (SD) has been extensively researched in the literature, particularly regarding control of individual and existing privacy management. However, far too little attention has been paid to other-generated disclosure (OGD), especially by insiders. OGD has a strong influence on self-presentation, self-image, and electronic word of mouth (eWOM). Moreover, OGD is more credible and less likely manipulated than SD, but lacks privacy control and legal protection to some extent. This article examines OGD in depth, ranging from motivation to both online and offline impacts, based upon lived experiences from both ‘the disclosed’ and ‘the discloser’. Using purposive sampling, this phenomenological study involves an online survey and in-depth interviews. The findings report the influence of peer disclosure as well as users’ strategies to mitigate privacy issues. This article also calls attention to the challenge of OGD privacy and inadequacies in the law related to privacy protection in the digital domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facebook" title="facebook">facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20privacy" title=" online privacy"> online privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=other-generated%20disclosure" title=" other-generated disclosure"> other-generated disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks%20sites%20%28SNSs%29" title=" social networks sites (SNSs)"> social networks sites (SNSs)</a> </p> <a href="https://publications.waset.org/abstracts/66391/other-generated-disclosure-a-challenge-to-privacy-on-social-network-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66391.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">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">199</span> Correlation between Diabetic Cataract, HBA1C and Gurakhu, a Clinical Study in Chhattisgarh State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bhattacharya">A.

It is formed in a non-enzymatic glycation pathway by hemoglobin's exposure to plasma glucose. In diabetes mellitus, higher amounts of glycated hemoglobin, indicating poorer control of blood glucose levels, have been associated with cardiovascular disease, nephropathy, and retinopathy. Guraku’s basic components are nicotine and jaggery, jaggery is made up of sugarcane so can have a diabetogenic potential which is exacerbated in presence of nicotine. This work had done with the aim to find correlation between Diabetic cataract, HbA1c and Guraku. Subjects were enrolled according to the inclusion and exclusion criteria. In this study total 75 subjects were included. In the study it was found that people consuming Guraku had a high level of HbA1c thus are more prone to the development of diabetic cataract. Male subjects are the more than female subjects. Most of the subjects belong to the lower socioeconomical class and not very educated. It could be concluded that this type of study could be useful in indentifying number of subjects suffering from diabetic cataract whose condition get worse by use of nicotine product like Guraku and preventive measure to be taken in prevention of this type of diabetic complication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetic%20cataract" title="diabetic cataract">diabetic cataract</a>, <a href="https://publications.waset.org/abstracts/search?q=HbA1c" title=" HbA1c"> HbA1c</a>, <a href="https://publications.waset.org/abstracts/search?q=Guraku" title=" Guraku"> Guraku</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetogenic%20potential" title=" diabetogenic potential "> diabetogenic potential </a> </p> <a href="https://publications.waset.org/abstracts/24572/correlation-between-diabetic-cataract-hba1c-and-gurakhu-a-clinical-study-in-chhattisgarh-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24572.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">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">198</span> Effect of Gamma Radiation on Bromophenol Blue Dyed Films as Dosimeter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20R.%20Oberoi">Priyanka R.

Numerous medical devices are sterilized by ionizing radiation. In the current research paper, an attempt was made to develop precise and inexpensive polymeric film dosimeter which can be used for controlling radiation dosage. Polymeric film containing (pH sensitive dye) indicator dye Bromophenol blue (BPB) was casted to check the effect of Gamma radiation on its optical and physical properties. The film was exposed to gamma radiation at 4 kGy/hr in the range of 0 to 300 kGy at an interval of 50 kGy. Release of vinyl acetate from an emulsion on high radiation reacts with the BPB fading the color of the film from blue to light blue and then finally colorless, indicating a change in pH from basic to acidic form. The change was characterized by using CIE l*a*b*, ultra-violet spectroscopy and FT-IR respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bromophenol%20blue" title="bromophenol blue">bromophenol blue</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimeter" title=" dosimeter"> dosimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a> </p> <a href="https://publications.waset.org/abstracts/55840/effect-of-gamma-radiation-on-bromophenol-blue-dyed-films-as-dosimeter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55840.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">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">197</span> Estimation of Desktop E-Wastes in Delhi Using Multivariate Flow Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumay%20Bhojwani">Sumay Bhojwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Chandra"> Ashutosh Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamita%20Devaburman"> Mamita Devaburman</a>, <a href="https://publications.waset.org/abstracts/search?q=Akriti%20Bhogal"> Akriti Bhogal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article uses the Material flow analysis for estimating e-wastes in the Delhi/NCR region. The Material flow analysis is based on sales data obtained from various sources. Much of the data available for the sales is unreliable because of the existence of a huge informal sector. The informal sector in India accounts for more than 90%. Therefore, the scope of this study is only limited to the formal one. Also, for projection of the sales data till 2030, we have used regression (linear) to avoid complexity. The actual sales in the years following 2015 may vary non-linearly but we have assumed a basic linear relation. The purpose of this study was to know an approximate quantity of desktop e-wastes that we will have by the year 2030 so that we start preparing ourselves for the ineluctable investment in the treatment of these ever-rising e-wastes. The results of this study can be used to install a treatment plant for e-wastes in Delhi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-wastes" title="e-wastes">e-wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=Delhi" title=" Delhi"> Delhi</a>, <a href="https://publications.waset.org/abstracts/search?q=desktops" title=" desktops"> desktops</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a> </p> <a href="https://publications.waset.org/abstracts/37549/estimation-of-desktop-e-wastes-in-delhi-using-multivariate-flow-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37549.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">258</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">196</span> Design of Decimation Filter Using Cascade Structure for Sigma Delta ADC </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Misbahuddin%20Mahammad">Misbahuddin Mahammad</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Chandra%20Sekhar"> P.

The decimation filters work twofold; they decimate the sampling rate by a factor of OSR (oversampling rate) and they remove the out band quantization noise resulting in an increase in resolution. The speed, area and power consumption of oversampled converter are governed largely by decimation filters in sigma-delta A/D converters. The scope of the work is to design a decimation filter for sigma-delta ADC and simulation using MATLAB. The decimation filter structure is based on cascaded-integrated comb (CIC) filter. A second decimation filter is using CIC for large rate change and cascaded FIR filters, for small rate changes, to improve the frequency response. The proposed structure is even more hardware efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sigma%20delta%20modulator" title="sigma delta modulator">sigma delta modulator</a>, <a href="https://publications.waset.org/abstracts/search?q=CIC%20filter" title=" CIC filter"> CIC filter</a>, <a href="https://publications.waset.org/abstracts/search?q=decimation%20filter" title=" decimation filter"> decimation filter</a>, <a href="https://publications.waset.org/abstracts/search?q=compensation%20filter" title=" compensation filter"> compensation filter</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20shaping" title=" noise shaping"> noise shaping</a> </p> <a href="https://publications.waset.org/abstracts/15366/design-of-decimation-filter-using-cascade-structure-for-sigma-delta-adc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15366.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">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">195</span> Field Saturation Flow Measurement Using Dynamic Passenger Car Unit under Mixed Traffic Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Chandra%20Majhi">Ramesh Chandra Majhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Saturation flow is a very important input variable for the design of signalized intersections. Saturation flow measurement is well established for homogeneous traffic. However, saturation flow measurement and modeling is a challenging task in heterogeneous characterized by multiple vehicle types and non-lane based movement. Present study focuses on proposing a field procedure for Saturation flow measurement and the effect of typical mixed traffic behavior at the signal as far as non-lane based traffic movement is concerned. Data collected during peak and off-peak hour from five intersections with varying approach width is used for validating the saturation flow model. The insights from the study can be used for modeling saturation flow and delay at signalized intersection in heterogeneous traffic conditions. <p class="card-text"><strong>Keywords:</strong> <a
