Moreover, the PEF-CSA is compared with two classical compressed indexing methods, Ferragina and Manzini implementation (FMI) and Sad-CSA on different type and size files in Pizza & Chili. The PEF-CSA performs better on the existing data in terms of the compression ratio, count, and locates time except for the evenly distributed data such as proteins data. The observations of the experiments are that the distribution of the φ is more important than the alphabet size on the compression ratio. Unevenly distributed data φ makes better compression effect, and the larger the size of the hit counts, the longer the count and locate time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressed%20suffix%20array" title="compressed suffix array">compressed suffix array</a>, <a href="https://publications.waset.org/abstracts/search?q=self-indexing" title=" self-indexing"> self-indexing</a>, <a href="https://publications.waset.org/abstracts/search?q=partitioned%20Elias-Fano" title=" partitioned Elias-Fano"> partitioned Elias-Fano</a>, <a href="https://publications.waset.org/abstracts/search?q=PEF-CSA" title=" PEF-CSA"> PEF-CSA</a> </p> <a href="https://publications.waset.org/abstracts/65986/compressed-suffix-arrays-to-self-indexes-based-on-partitioned-elias-fano" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65986.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">252</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">88</span> The Food and Nutritional Effects of Smallholders’ Participation in Milk Value Chain in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geday%20Elias">Geday Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaigne%20Etienne"> Montaigne Etienne</a>, <a href="https://publications.waset.org/abstracts/search?q=Padilla%20Martine"> Padilla Martine</a>, <a href="https://publications.waset.org/abstracts/search?q=Tollossa%20Degefa"> Tollossa Degefa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smallholder farmers’ participation in agricultural value chain identified as a pathway to get out of poverty trap in Ethiopia. The smallholder dairy activities have a huge potential in poverty reduction through enhancing income, achieving food and nutritional security in the country. However, much less is known about the effects of smallholder’s participation in milk value chain on household food security and nutrition. This paper therefore, aims at evaluating the effects of smallholders’ participation in milk value chain on household food security taking in to account the four pillars of food security measurements (availability, access, utilization and stability). Using a semi-structured interview, a cross sectional farm household data collected from a randomly selected sample of 333 households (170 in Amhara and 163 in Oromia regions).Binary logit and propensity score matching( PSM) models are employed to examine the mechanisms through which smallholder’s participation in the milk value chain affects household food security where crop production, per capita calorie intakes, diet diversity score, and food insecurity access scale are used to measure food availability, access, utilization and stability respectively. Our findings reveal from 333 households, only 34.5% of smallholder farmers are participated in the milk value chain. Limited access to inputs and services, limited access to inputs markets and high transaction costs are key constraints for smallholders’ limited access to the milk value chain. To estimate the true average participation effects of milk value chain for participated households, the outcome variables (food security) of farm households who participated in milk value chain are compared with the outcome variables if the farm households had not participated. The PSM analysis reveals smallholder’s participation in milk value chain has a significant positive effect on household income, food security and nutrition. Smallholder farmers who are participated in milk chain are better by 15 quintals crops production and 73 percent of per capita calorie intakes in food availability and access respectively than smallholder farmers who are not participated in the market. Similarly, the participated households are better in dietary quality by 112 percents than non-participated households. Finally, smallholders’ who are participated in milk value chain are better in reducing household vulnerability to food insecurity by an average of 130 percent than non participated households. The results also shows income earned from milk value chain participation contributed to reduce capital’s constraints of the participated households’ by higher farm income and total household income by 5164 ETB and 14265 ETB respectively. This study therefore, confirms the potential role of smallholders’ participation in food value chain to get out of poverty trap through improving rural household income, food security and nutrition. Therefore, identified the determinants of smallholder participation in milk value chain and the participation effects on food security in the study areas are worth considering as a positive knock for policymakers and development agents to tackle the poverty trap in the study area in particular and in the country in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effects" title="effects">effects</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security%20and%20nutrition" title=" food security and nutrition"> food security and nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=participation" title=" participation"> participation</a>, <a href="https://publications.waset.org/abstracts/search?q=smallholders" title=" smallholders"> smallholders</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20chain" title=" value chain"> value chain</a> </p> <a href="https://publications.waset.org/abstracts/41423/the-food-and-nutritional-effects-of-smallholders-participation-in-milk-value-chain-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41423.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">339</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">87</span> Sugarcane Trash Biochar: Effect of the Temperature in the Porosity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20T.%20Nakashima">Gabriela T.

Yamaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biochar can be an alternative to use sugarcane trash. Biochar is a solid material obtained from pyrolysis, that is a biomass thermal degradation with low or no O₂ concentration. Pyrolysis transforms the carbon that is commonly found in other organic structures into a carbon with more stability that can resist microbial decomposition. Biochar has a versatility of uses such as soil fertility, carbon sequestration, energy generation, ecological restoration, and soil remediation. Biochar has a great ability to retain water and nutrients in the soil so that this material can improve the efficiency of irrigation and fertilization. The aim of this study was to characterize biochar produced from sugarcane trash in three different pyrolysis temperatures and determine the lowest temperature with the high yield and carbon content. Physical characterization of this biochar was performed to help the evaluation for the best production conditions. Sugarcane (Saccharum officinarum) trash was collected at Corredeira Farm, located in Ibaté, São Paulo State, Brazil. The farm has 800 hectares of planted area with an average yield of 87 t·ha⁻¹. The sugarcane varieties planted on the farm are: RB 855453, RB 867515, RB 855536, SP 803280, SP 813250. Sugarcane trash was dried and crushed into 50 mm pieces. Crucibles and lids were used to settle the sugarcane trash samples. The higher amount of sugarcane trash was added to the crucible to avoid the O₂ concentration. Biochar production was performed in three different pyrolysis temperatures (200°C, 325°C, 450°C) in 2 hours residence time in the muffle furnace. Gravimetric yield of biochar was obtained. Proximate analysis of biochar was done using ASTM E-872 and ABNT NBR 8112. Volatile matter and ash content were calculated by direct weight loss and fixed carbon content calculated by difference. Porosity measurement was evaluated using an automatic gas adsorption device, Autosorb-1, with CO₂ described by Nakatani. Approximately 0.5 g of biochar in 2 mm particle sizes were used for each measurement. Vacuum outgassing was performed as a pre-treatment in different conditions for each biochar temperature. The pore size distribution of micropores was determined using Horváth-Kawazoe method. Biochar presented different colors for each treatment. Biochar - 200°C presented a higher number of pieces with 10mm or more and did not present the dark black color like other treatments after 2 h residence time in muffle furnace. Also, this treatment had the higher content of volatiles and the lower amount of fixed carbon. In porosity analysis, while the temperature treatments increase, the amount of pores also increase. The increase in temperature resulted in a biochar with a better quality. The pores in biochar can help in the soil aeration, adsorption, water retention.

This work presents results obtained by multi-criteria decision analysis, and it establishes a hierarchy, regarding the installation of wind farms, among geopolicy regions in the state of ‘Rio de Janeiro’, Brazil: ‘Regiao Norte-RN’, ‘Regiao dos Lagos-RL’ and ‘Regiao Serrana-RS’. The wind regime map indicates only these three possible regions with an average annual wind speed of above of 6.0 m/s. The method applied was the Analytical Hierarchy Process-AHP, designed to prioritize and rank the three regions based on four criteria as follows: 1) potential of the site and average wind speeds of above 6.0 ms-¹, 2) average land value, 3) distribution and interconnection to electric network with the highest number of electricity stations, and 4) accessibility with proximity and quality of highways and flat topography. The values of energy generation were calculated for wind turbines 50, 75, and 100 meters high, considering the production of site (GWh/Km²) and annual production (GWh). The weight of each criterion was attributed by six engineers and by analysis of Road Map, the Map of the Electric System, the Map of Wind Regime and the Annual Land Value Report. The results indicated that in 'RS', the demand was estimated at 2,000 GWh, so a wind farm can operate efficiently in 50 m turbines. This region is mainly mountainous with difficult access and lower land value. With respect to ‘RL’, the wind turbines have to be installed at a height of 75 m high to reach a demand of 6,300 GWh. This region is very flat, with easy access, and low land value. Finally, the ‘NR’ was evaluated as very flat and with expensive lands. In this case, wind turbines with 100 m can reach an annual production of 19,000 GWh. In this Region, the coast area was classified as of greater logistic, productivity and economic potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AHP" title="AHP">AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title=" wind energy"> wind energy</a> </p> <a href="https://publications.waset.org/abstracts/88888/multi-criterial-analysis-potential-regions-and-height-of-wind-turbines-rio-de-janeiro-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88888.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">151</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">85</span> Design of a Dietetic Food: Case of Lebanese Kishk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Henri%20El%20Zakhem">Henri El Zakhem</a>, <a href="https://publications.waset.org/abstracts/search?q=Dona%20Shalhoub"> Dona Shalhoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Atallah"> Elias Atallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Koura"> Jessica Koura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increase of demand on dietetic food and the need for more types of diet food, the production of dietetic food is increasing and improving. This demand on dietetic food has triggered us to study the market in which we found that Kishk (Lebanese dairy product) diet is not available. Production of a low fat product which is diet Kishk was our concern. A strategy was followed to choose the right idea that will satisfy the need of the market. The whole process was studied and explained thoroughly. The percentage of fat was found to be 32.52 % in regular Kishk and 3.84 % in the diet Kishk produced. The new product has the advantage to be high in protein, low in fat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20and%20industrialization" title="design and industrialization">design and industrialization</a>, <a href="https://publications.waset.org/abstracts/search?q=dietetic" title=" dietetic"> dietetic</a>, <a href="https://publications.waset.org/abstracts/search?q=diet%20Kishk" title=" diet Kishk"> diet Kishk</a>, <a href="https://publications.waset.org/abstracts/search?q=fat" title=" fat"> fat</a> </p> <a href="https://publications.waset.org/abstracts/58410/design-of-a-dietetic-food-case-of-lebanese-kishk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58410.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">375</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">84</span> A Multi-Level Approach to Improve Sustainability Performances of Industrial Agglomerations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Innocenti">Patrick Innocenti</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Montini"> Elias Montini</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Menato"> Silvia Menato</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzio%20Sorlini"> Marzio Sorlini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Documented experiences of industrial symbiosis are always triggered and driven only by economic goals: environmental and (even rarely) social results are sometimes assessed and declared as effects of virtuous behaviours, but are merely casual and un-pursued side externalities.

Biological methods go beyond the chemical and physical synthesis that is expensive and not friendly to the environment. Therefore, in this study, silver nanoparticles were synthesized biologically in an environmentally friendly way by Handroanthus chrysanthus flower aqueous extract (AgNPs) that contains phytochemicals capable of reducing silver nitrate. AgNPs were characterized visually by UV-visible spectroscopy and TEM. The antimicrobial activity of the AgNPs was tested by determining the minimum inhibitory concentration (MIC), and minimal bactericidal concentration (MBC) in Escherichia coli and Staphylococcus aureus strains AgNPs showed potent antimicrobial activity against gram-negative and gram-positive bacteria. MIC and MBC values were as low as 41.6, and 83.2 ug/mL using AgNPs biosynthesized by H. chrysanthus flower extract. This nanoparticle could be the basis for the formulation of disinfectants for use in the food and pharmaceutical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=flower%20extract" title=" flower extract"> flower extract</a>, <a href="https://publications.waset.org/abstracts/search?q=Handroanthus" title=" Handroanthus"> Handroanthus</a> </p> <a href="https://publications.waset.org/abstracts/161062/antimicrobial-activity-of-biosynthesized-silver-nanoparticles-with-handroanthus-chrysanthus-flower-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161062.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">112</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">82</span> A Network-Theorical Perspective on Music Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Alcal%C3%A1-Alvarez">Alberto Alcalá-Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Padilla-Longoria"> Pablo Padilla-Longoria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper describes a framework for constructing mathematical networks encoding relevant musical information from a music score for structural analysis. These graphs englobe statistical information about music elements such as notes, chords, rhythms, intervals, etc., and the relations among them, and so become helpful in visualizing and understanding important stylistic features of a music fragment. In order to build such networks, musical data is parsed out of a digital symbolic music file. This data undergoes different analytical procedures from Graph Theory, such as measuring the centrality of nodes, community detection, and entropy calculation. The resulting networks reflect important structural characteristics of the fragment in question: predominant elements, connectivity between them, and complexity of the information contained in it. Music pieces in different styles are analyzed, and the results are contrasted with the traditional analysis outcome in order to show the consistency and potential utility of this method for music analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20musicology" title="computational musicology">computational musicology</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20music%20modelling" title=" mathematical music modelling"> mathematical music modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20analysis" title=" music analysis"> music analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=style%20classification" title=" style classification"> style classification</a> </p> <a href="https://publications.waset.org/abstracts/163401/a-network-theorical-perspective-on-music-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163401.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">102</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">81</span> Proposal to Increase the Efficiency, Reliability and Safety of the Centre of Data Collection Management and Their Evaluation Using Cluster Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Juhas">Martin Juhas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bohuslava%20Juhasova"> Bohuslava Juhasova</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Halenar"> Igor Halenar</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrej%20Elias"> Andrej Elias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article deals with the possibility of increasing efficiency, reliability and safety of the system for teledosimetric data collection management and their evaluation as a part of complex study for activity “Research of data collection, their measurement and evaluation with mobile and autonomous units” within project “Research of monitoring and evaluation of non-standard conditions in the area of nuclear power plants”.

The deposition conditions for production of Ni-W coatings have been optimized for peak performance of their electrocatalytic activity, namely hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The corrosion behavior of the coatings were tested under working conditions of electrocatalysis (1M KOH). Electrocatalytic behaviours were tested by cyclic voltammetry and chrono-potentiometry techniques. Experimental results demonstrated that Ni-W coatings at low and high current densities (c. d.) showing superior performance for OER and HER respectively. The increased electrocatalytic activity for HER with increase of deposition c. d. was attributed to the phase structure, surface morphology and chemical composition of the coatings, confirmed by XRD, SEM and EDX analysis, respectively. The dependency of hardness and thickness of the coatings on HER and OER were examined, and results were discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocatalytic%20behavior" title="electrocatalytic behavior">electrocatalytic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=HER" title=" HER"> HER</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni-W%20alloy" title=" Ni-W alloy"> Ni-W alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=OER" title=" OER"> OER</a> </p> <a href="https://publications.waset.org/abstracts/17794/ni-w-alloy-coatings-a-promising-electrode-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17794.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">416</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">77</span> Vertical Distribution of Heavy Metals and Enrichment in Core Marine Sediments of East Malaysia by INAA and ICP-MS </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Ashraf">Ahmadreza Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Saion"> Elias Saion</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Gharib%20Shahi"> Elham Gharib Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chee%20Kong%20Yap"> Chee Kong Yap</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Suhaimi%20Hamzah"> Mohd Suhaimi Hamzah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fifty-five core marine sediments from three locations at South China Sea and one location each at Sulu Sea and Sulawesi Sea of coastal East Malaysia was analyzed for heavy metals using Instrumental Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectroscopy.

This data is important due to the fact that a person can communicate more effectively with emotions than can be possible with words. This information can be processed through technological components like Facial Recognition, Gait Recognition or Gesture Recognition. As of now, solutions proposed using this technology only consider one component at a given moment. This research investigation proposes two solutions based on Affective Computing taking into account more than one component for emotion detection. The proposals reflect the levels of dependency between hardware devices and software, as well as the interaction process between the system and the user which implies the development of scenarios where both proposals will be put to the test in a live environment. Both solutions are to be developed in code by software engineers to prove the feasibility. To validate the impact on society and business interest, interviews with stakeholders are conducted with an investment mind set where each solution is labeled on a scale of 1 through 5, being one a minimum possible investment and 5 the maximum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affective%20computing" title="affective computing">affective computing</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion%20detection" title=" emotion detection"> emotion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20recognition" title=" face recognition"> face recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=gait%20recognition" title=" gait recognition"> gait recognition</a> </p> <a href="https://publications.waset.org/abstracts/43577/proposed-solutions-based-on-affective-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43577.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">369</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">74</span> Carbohydrate Intake Estimation in Type I Diabetic Patients Described by UVA/Padova Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20A.%20Padilla">David A.

However, the controller itself is unable to define a suitable reference trajectory for glucose. In this paper, a control strategy Is proposed where the shape of the reference trajectory is generated bases in the amount of carbohydrates present during the digestive process, due to the effect of carbohydrate intake. Since there no exists a sensor to measure the amount of carbohydrates consumed, an estimator is proposed. Thus this paper presents the entire process of designing a carbohydrate estimator, which allows estimate disturbance for a predictive controller (MPC) in a T1MD patient, the estimation will be used to establish a profile of reference and improve the response of the controller by providing the estimated information of ingested carbohydrates. The dynamics of the diabetic model used are due to the equations described by the UVA/Padova model of the T1DMS simulator, the system was developed and simulated in Simulink, taking into account the noise and limitations of the glucose control system actuators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=estimation" title="estimation">estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=glucose%20control" title=" glucose control"> glucose control</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20controller" title=" predictive controller"> predictive controller</a>, <a href="https://publications.waset.org/abstracts/search?q=MPC" title=" MPC"> MPC</a>, <a href="https://publications.waset.org/abstracts/search?q=UVA%2FPadova" title=" UVA/Padova"> UVA/Padova</a> </p> <a href="https://publications.waset.org/abstracts/115938/carbohydrate-intake-estimation-in-type-i-diabetic-patients-described-by-uvapadova-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115938.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">261</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">73</span> Reciprocal Interferences in Bilingual English-Igbo Speaking Society: The Implications in Language Pedagogy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ugwu%20Elias%20Ikechukwu">Ugwu Elias Ikechukwu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discussions on bilingualism have always dwelt on how the mother tongue interferes with the target language. This interference is considered a serious problem in second language learning. Usually, the interference has been phonological. But the objective of this research is to explore how the target language interferes with the mother tongue. In the case of the Igbo language, it interferes with English mostly at the phonological level while English interferes with Igbo at the realm of vocabulary. The result is a new language \"Engligbo\" which is a hybrid of English and Igbo. The Igbo language spoken by about 25 million people is one of the three most prominent languages in Nigeria. This paper discusses the phenomenal Engligbo, and other implications for Igbo learners of English. The method of analysis is descriptive. A number of recommendations were made that would help teachers handle problems arising from such mutual interferences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reciprocal%20interferences" title="reciprocal interferences">reciprocal interferences</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title=" bilingualism"> bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=implications" title=" implications"> implications</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20pedagogy" title=" language pedagogy "> language pedagogy </a> </p> <a href="https://publications.waset.org/abstracts/3835/reciprocal-interferences-in-bilingual-english-igbo-speaking-society-the-implications-in-language-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3835.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">399</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">72</span> Self Immolation and the Deactivation of State Necropower</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kate%20L.%20Yusi">Kate L.

In this paper, the writer seeks to focus on self-immolation by Tibetan monks and other activists against Chinese imperialism, its continuing ethnic cleansing of the Tibetan people, forced assimilation, and territorial occupation. Here, the main driving force is this question: what does self-immolation mean to a people who are forced to live in deathspace? In other words, if one is reduced to nothingness that their deaths (as is their lives) become insignificant, in what ways does the reclamation of death/dying become a “way out” of this state-imposed enclave of death? To answer these questions, the writer engages with and put in conversation the works of Achille Mbembe, Elias Cannetti, and Giorgio Agamben. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=necropolitics" title="necropolitics">necropolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20immolation" title=" self immolation"> self immolation</a>, <a href="https://publications.waset.org/abstracts/search?q=tibetan%20people" title=" tibetan people"> tibetan people</a>, <a href="https://publications.waset.org/abstracts/search?q=chinese%20imperialism" title=" chinese imperialism"> chinese imperialism</a> </p> <a href="https://publications.waset.org/abstracts/153517/self-immolation-and-the-deactivation-of-state-necropower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153517.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">114</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">71</span> Numerical Study for the Estimation of Hydrodynamic Current Drag Coefficients for the Colombian Navy Frigates Using Computational Fluid Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Gracia">Mauricio Gracia</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Leal"> Luis Leal</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Verma"> Bharat Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics (CFD) has become nowadays an important tool in the process of hydrodynamic design of modern ships. CFD is used to model any phenomena related to fluid flow in a control volume like a ship or any offshore structure in the sea. In the present study, the current force drag coefficients for a Colombian Navy Frigate in deep and shallow water are estimated through the application of CFD. The study shows the process of simulating the ship current drag coefficients using the CFD simulations method, which is conducted using STAR-CCM+ software package. The Almirante Padilla class Frigate ship scale model is investigated. The results show the ship current drag coefficient calculated considering a current speed of 1 knot with a 90° drift angle for the full-scale ship. Predicted results were compared against the current drag coefficients published in the Lloyds register OCIMF report. It is shown that the simulation results agree fairly well with the published results and that STAR-CCM+ code can predict current drag coefficients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20draft%20coefficient" title=" current draft coefficient"> current draft coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=STAR-CCM%2B" title=" STAR-CCM+"> STAR-CCM+</a>, <a href="https://publications.waset.org/abstracts/search?q=OCIMF" title=" OCIMF"> OCIMF</a>, <a href="https://publications.waset.org/abstracts/search?q=Bollard%20pull" title=" Bollard pull"> Bollard pull</a> </p> <a href="https://publications.waset.org/abstracts/132520/numerical-study-for-the-estimation-of-hydrodynamic-current-drag-coefficients-for-the-colombian-navy-frigates-using-computational-fluid-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132520.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">174</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">70</span> Microstructural Investigations of Metal Oxides Encapsulated Thermochromic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Emirov">Yusuf Emirov</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullatif%20Hakami"> Abdullatif Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20K%20Biswas"> Prasanta K Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20K%20Stefanakos"> Elias K Stefanakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesha%20S%20Srinivasan"> Sesha S Srinivasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is aimed to develop microencapsulated thermochromic materials and the analysis of core-shell formation using high resolution electron microscopy.

Given its relevance, it is an active field for microeconomic and statistical research. Price elasticity in the industry of oil and gas, in particular for fuels sold in gas stations, has shown to be a challenging topic given the market and state restrictions, and underlying correlations structures between the types of fuels sold by the same gas station. This paper explores the Lotka-Volterra model for the problem for price elasticity estimation in the context of fuels; in addition, it is introduced multivariate random effects with the purpose of dealing with errors, e.g., measurement or missing data errors. In order to model the underlying correlation structures, the Inverse-Wishart, Hierarchical Half-t and LKJ distributions are studied. Here, the Bayesian paradigm through Markov Chain Monte Carlo (MCMC) algorithms for model estimation is considered. Simulation studies covering a wide range of situations were performed in order to evaluate parameter recovery for the proposed models and algorithms. Results revealed that the proposed algorithms recovered quite well all model parameters. Also, a real data set analysis was performed in order to illustrate the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=price%20elasticity" title="price elasticity">price elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=volume" title=" volume"> volume</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation%20structures" title=" correlation structures"> correlation structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20models" title=" Bayesian models"> Bayesian models</a> </p> <a href="https://publications.waset.org/abstracts/122666/a-bayesian-multivariate-microeconometric-model-for-estimation-of-price-elasticity-of-demand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122666.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">165</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">68</span> Design, Construction and Evaluation of Ultra-High-Performance Concrete (UHPC) Bridge Deck Overlays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jordy%20Padilla">Jordy Padilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The New Jersey Department of Transportation (NJDOT) initiated a research project to install and evaluate Ultra-High-Performance Concrete (UHPC) as an overlay on existing bridges. The project aims to implement UHPC overlays in NJDOT bridge deck strategies for preservation and repair. During design, four bridges were selected for construction. The construction involved the removal of the existing bridge asphalt overlays, partially removing the existing concrete deck surface, and resurfacing the deck with a UHPC overlay. In some cases, a new asphalt riding surface was placed. Additionally, existing headers were replaced with full-depth UHPC. The UHPC overlay is monitored through coring and Non-destructive testing (NDT) to ensure that the interfacial bond is intact and that the desired conditions are maintained. The NDT results show no evidence that the bond between the new UHPC overlay and the existing concrete deck is compromised. Bond strength test data demonstrates that, in general, the desired bond was achieved between UHPC and the substrate concrete, although the results were lower than anticipated. Chloride content is also within expectations except for one anomaly. The baseline testing was successful, and no significant defects were encountered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra-high%20performance%20concrete" title="ultra-high performance concrete">ultra-high performance concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20testing" title=" non-destructive testing"> non-destructive testing</a> </p> <a href="https://publications.waset.org/abstracts/167006/design-construction-and-evaluation-of-ultra-high-performance-concrete-uhpc-bridge-deck-overlays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167006.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">80</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">67</span> Homomorphic Conceptual Framework for Effective Supply Chain Strategy (HCEFSC) within Operational Research (OR) with Sustainability and Phenomenology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussain%20Abdullah%20Al-Salamin">Hussain Abdullah Al-Salamin</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Ogutu%20Azariah%20Tembe"> Elias Ogutu Azariah Tembe </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Supply chain (SC) is an operational research (OR) approach and technique which acts as catalyst within central nervous system of business today.

After watching each clip, participants took a listening comprehension test. At the end of the experiment, participants completed a questionnaire to measure their perceptions about the use of captions and the video clips they watched. Results indicated that the full captioning group significantly outperformed both the keyword captioning and the no captioning group on the listening comprehension tests.

Due to threshold structures commonly occurring in CRR models, the associated mathematical optimization problems have the significant characteristic of being strongly non-differentiable. In order to face this enormous task, the resolution method proposed adopts a smoothing strategy using a special C∞ differentiable class function. The final estimation solution is obtained by solving a sequence of differentiable subproblems which gradually approach the original conceptual problem. The use of this technique, called Hyperbolic Smoothing Method (HSM), makes possible the application of the most powerful minimization algorithms, and also allows for the main difficulties presented by the original CRR problem to be overcome. A set of computational experiments is presented for the purpose of illustrating both the reliability and the efficiency of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rainfall-runoff%20models" title="rainfall-runoff models">rainfall-runoff models</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20calibration" title=" automatic calibration"> automatic calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20smoothing%20method" title=" hyperbolic smoothing method"> hyperbolic smoothing method</a> </p> <a href="https://publications.waset.org/abstracts/123935/the-hyperbolic-smoothing-approach-for-automatic-calibration-of-rainfall-runoff-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123935.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">64</span> Maximizing Coverage with Mobile Crime Cameras in a Stochastic Spatiotemporal Bipartite Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%28Ted%29%20Edward%20Holmberg">(Ted) Edward Holmberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Abdelguerfi"> Mahdi Abdelguerfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Ioup"> Elias Ioup</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research details a coverage measure for evaluating the effectiveness of observer node placements in a spatial bipartite network.

The HHDPA was previously synthesized and characterized by FT-IR, 1H NMR, 31P NMR spectroscopy and elemental analysis. The effects contact time, initial pH, initial metal concentration, aqueous/organic phase ratio, extractant concentration and temperature on the extraction process have been studied. An empirical modelling was performed by using a 25 full factorial design, and regression equation for extraction metals was determined from the data. The conventional log-log analysis of the extraction data reveals that ratios of extractant to extracted U(VI), Pu(IV) and Th(IV) are 1:1, 1:2 and 1:2, respectively. Thermodynamic parameters showed that the extraction process was exothermic heat and spontaneous. The obtained optimal parameters were applied to real efﬂuents containing uranium(VI), plutonium(IV) and thorium(IV) ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title="solvent extraction">solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a>, <a href="https://publications.waset.org/abstracts/search?q=plutonium" title=" plutonium"> plutonium</a>, <a href="https://publications.waset.org/abstracts/search?q=thorium" title=" thorium"> thorium</a>, <a href="https://publications.waset.org/abstracts/search?q=1-hydroxyhexadecylidene-1-1-diphosphonic%20acid" title=" 1-hydroxyhexadecylidene-1-1-diphosphonic acid"> 1-hydroxyhexadecylidene-1-1-diphosphonic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/37851/the-solvent-extraction-of-uranium-plutonium-and-thorium-from-aqueous-solution-by-1-hydroxyhexadecylidene-11-diphosphonic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37851.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">288</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">61</span> Microstructure Characterization on Silicon Carbide Formation from Natural Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor%20Leha%20Abdul%20Rahman">Noor Leha Abdul Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Koay%20Mei%20Hyie"> Koay Mei Hyie</a>, <a href="https://publications.waset.org/abstracts/search?q=Anizah%20Kalam"> Anizah Kalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Husna%20Elias"> Husna Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=Teng%20Wang%20Dung"> Teng Wang Dung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dark Red Meranti and Kapur, kinds of important type of wood in Malaysia were used as a precursor to fabricate porous silicon carbide. A carbon template is produced by pyrolysis at 850°C in an oxygen free atmosphere. The carbon template then further subjected to infiltration with silicon by silicon melt infiltration method. The infiltration process was carried out in tube furnace in argon flow at 1500°C, at two different holding time; 2 hours and 3 hours. Thermo gravimetric analysis was done to investigate the decomposition behavior of two species of plants. The resulting silicon carbide was characterized by XRD which was found the formation of silicon carbide and also excess silicon. The microstructure was characterized by scanning electron microscope (SEM) and the density was determined by the Archimedes method. An increase in holding time during infiltration will increased the density as well as formation of silicon carbide. Dark Red Meranti precursor is likely suitable for production of silicon carbide compared to Kapur. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density" title="density">density</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20carbide" title=" silicon carbide"> silicon carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD "> XRD </a> </p> <a href="https://publications.waset.org/abstracts/30071/microstructure-characterization-on-silicon-carbide-formation-from-natural-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30071.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">424</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">60</span> Improving the Analytical Power of Dynamic DEA Models, by the Consideration of the Shape of the Distribution of Inputs/Outputs Data: A Linear Piecewise Decomposition Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elias%20K.%20Maragos">Elias K.

Maravelakis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Dynamic Data Envelopment Analysis (DDEA), which is a subfield of Data Envelopment Analysis (DEA), the productivity of Decision Making Units (DMUs) is considered in relation to time. In this case, as it is accepted by the most of the researchers, there are outputs, which are produced by a DMU to be used as inputs in a future time. Those outputs are known as intermediates. The common models, in DDEA, do not take into account the shape of the distribution of those inputs, outputs or intermediates data, assuming that the distribution of the virtual value of them does not deviate from linearity. This weakness causes the limitation of the accuracy of the analytical power of the traditional DDEA models. In this paper, the authors, using the concept of piecewise linear inputs and outputs, propose an extended DDEA model. The proposed model increases the flexibility of the traditional DDEA models and improves the measurement of the dynamic performance of DMUs. <p class="card-text"><strong>Keywords:</strong> <a
