Unfortunately, most production systems such as customer demands are stochastic. Demand-Driven MRP (DDMRP) is a new approach for inventory control system, and it deals with demand uncertainty. The objective of this paper is to compare the MRP and DDMRP work for a long lead time and uncertain demand in terms of on-hand inventory levels. The evaluation is conducted through a discrete event simulation using purchased part data from an automotive company. The result is MRP gives 50,759 pcs / day while DDMRP gives 34,835 pcs / day (reduce 32%), it means DDMRP is more effective inventory control than MRP in terms of on-hand inventory levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Demand-Driven%20MRP" title="Demand-Driven MRP">Demand-Driven MRP</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20lead%20time" title=" long lead time"> long lead time</a>, <a href="https://publications.waset.org/abstracts/search?q=MRP" title=" MRP"> MRP</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertain%20demand" title=" uncertain demand"> uncertain demand</a> </p> <a href="https://publications.waset.org/abstracts/71415/inventory-control-for-purchased-part-under-long-lead-time-and-uncertain-demand-mrp-vs-demand-driven-mrp-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71415.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">307</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">86</span> Low-Level Modeling for Optimal Train Routing and Scheduling in Busy Railway Stations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quoc%20Khanh%20Dang">Quoc Khanh Dang</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Bourdeaud%E2%80%99huy"> Thomas Bourdeaud’huy</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Mesghouni"> Khaled Mesghouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Armand%20Toguy%C2%B4eni"> Armand Toguy´eni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies a train routing and scheduling problem for busy railway stations. Our objective is to allow trains to be routed in dense areas that are reaching saturation. Unlike traditional methods that allocate all resources to setup a route for a train and until the route is freed, our work focuses on the use of resources as trains progress through the railway node. This technique allows a larger number of trains to be routed simultaneously in a railway node and thus reduces their current saturation. To deal with this problem, this study proposes an abstract model and a mixed-integer linear programming formulation to solve it. The applicability of our method is illustrated on a didactic example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=busy%20railway%20stations" title="busy railway stations">busy railway stations</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed-integer%20linear%20programming" title=" mixed-integer linear programming"> mixed-integer linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=offline%20railway%20station%20management" title=" offline railway station management"> offline railway station management</a>, <a href="https://publications.waset.org/abstracts/search?q=train%20platforming" title=" train platforming"> train platforming</a>, <a href="https://publications.waset.org/abstracts/search?q=train%20routing" title=" train routing"> train routing</a>, <a href="https://publications.waset.org/abstracts/search?q=train%20scheduling" title=" train scheduling"> train scheduling</a> </p> <a href="https://publications.waset.org/abstracts/108783/low-level-modeling-for-optimal-train-routing-and-scheduling-in-busy-railway-stations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108783.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">259</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> On the Girth of the Regular Digraph of Ideals of a ‎Commutative ‎Ring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Karimi">Masoud Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ‎Let R be a commutative ring‎. ‎The regular digraph of ideals of R, which is denoted by‎ Γ(R)‎, ‎is a digraph whose vertex-set is the set of all ‎non-‎trivial ideals of R and‎, ‎for every‎ two distinct vertices I and J‎, ‎there is an arc from I to J‎, ‎whenever I contains‎ a non-zero-divisor on J.

May</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge of the thermophysical properties of complex mixtures at extreme conditions of pressure and temperature have always been essential to the Liquefied Natural Gas (LNG) industry’s evolution because of the tremendous technical challenges present at all stages in the supply chain from production to liquefaction to transport. Each stage is designed using predictions of the mixture’s properties, such as density, viscosity, surface tension, heat capacity and phase behaviour as a function of temperature, pressure, and composition. Unfortunately, currently available models lead to equipment over-designs of 15% or more. To achieve better designs that work more effectively and/or over a wider range of conditions, new fundamental property data are essential, both to resolve discrepancies in our current predictive capabilities and to extend them to the higher-pressure conditions characteristic of many new gas fields. Furthermore, innovative experimental techniques are required to measure different thermophysical properties at high pressures and over a wide range of temperatures, including near the mixture’s critical points where gas and liquid become indistinguishable and most existing predictive fluid property models used breakdown. In this work, we present a wide range of experimental measurements made for different binary and ternary mixtures relevant to LNG processing, with a particular focus on viscosity, surface tension, heat capacity, bubble-points and density. For this purpose, customized and specialized apparatus were designed and validated over the temperature range (200 to 423) K at pressures to 35 MPa. The mixtures studied were (CH4 + C3H8), (CH4 + C3H8 + CO2) and (CH4 + C3H8 + C7H16); in the last of these the heptane contents was up to 10 mol %. Viscosity was measured using a vibrating wire apparatus, while mixture densities were obtained by means of a high-pressure magnetic-suspension densimeter and an isochoric cell apparatus; the latter was also used to determine bubble-points. Surface tensions were measured using the capillary rise method in a visual cell, which also enabled the location of the mixture critical point to be determined from observations of critical opalescence. Mixture heat capacities were measured using a customised high-pressure differential scanning calorimeter (DSC). The combined standard relative uncertainties were less than 0.3% for density, 2% for viscosity, 3% for heat capacity and 3 % for surface tension. The extensive experimental data gathered in this work were compared with a variety of different advanced engineering models frequently used for predicting thermophysical properties of mixtures relevant to LNG processing. In many cases the discrepancies between the predictions of different engineering models for these mixtures was large, and the high quality data allowed erroneous but often widely-used models to be identified. The data enable the development of new or improved models, to be implemented in process simulation software, so that the fluid properties needed for equipment and process design can be predicted reliably. This in turn will enable reduced capital and operational expenditure by the LNG industry. The current work also aided the community of scientists working to advance theoretical descriptions of fluid properties by allowing to identify deficiencies in theoretical descriptions and calculations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LNG" title="LNG">LNG</a>, <a href="https://publications.waset.org/abstracts/search?q=thermophysical" title=" thermophysical"> thermophysical</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20tension" title=" surface tension"> surface tension</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20capacity" title=" heat capacity"> heat capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=bubble%20points" title=" bubble points"> bubble points</a>, <a href="https://publications.waset.org/abstracts/search?q=models" title=" models"> models</a> </p> <a href="https://publications.waset.org/abstracts/55785/high-pressure-thermophysical-properties-of-complex-mixtures-relevant-to-liquefied-natural-gas-lng-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55785.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">276</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">83</span> Epidemiology and Jeopardy Aspect of Febrile Neutropenia Patients by Means of Infectious Maladies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Karimi">Pouya Karimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Ghasemi%20Shayan"> Ramin Ghasemi Shayan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conclusions of the sort and setting of observational treatment for immunocompromised patients with fever are confused by the qualities of the hidden disease and the impacts of medications previously got, just as by changing microbiological examples and patterns in sedate obstruction at national and institutional levels.

In the main of article , researchers have discussed why life skills training does not have much effect on some emotional problems .Despite the fact that life skills training had a positive effect on these spouses, but due to the stress of women with AIDS spouses, life skills training did not show much effectiveness, and for outstanding effects, there is a need for individual psychological treatments and broader social support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiv" title="Hiv">Hiv</a>, <a href="https://publications.waset.org/abstracts/search?q=aids" title=" aids"> aids</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20suport" title=" social suport"> social suport</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20skills" title=" life skills"> life skills</a> </p> <a href="https://publications.waset.org/abstracts/177876/a-study-of-mental-health-of-wife-of-patients-with-hiv-and-effects-of-life-skills-on-promotion-of-their-mental-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177876.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">76</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> Cause of the Disappearance of Wild Bees in Kinshasa, Democratic Republic of Congo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Ekuwo%20Okende">Sarah Ekuwo Okende</a>, <a href="https://publications.waset.org/abstracts/search?q=Armand%20Lokolo"> Armand Lokolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gradually, the recognition of wild bees in processes affecting ecosystems and as major components of biodiversity has led to their protection as well as their areas in Kinshasa. And despite their decisive role in the well-being of men, the general public and decision-makers know nothing of the consequences of the loss of these, which are nevertheless of considerable magnitude. On this, they provide the pollination of sexual plants, and they also provide us with a number of goods that have a direct economic value, such as food, medicines, etc. And yet today, more than half of these wild bee species are threatened in Kinshasa. The causes of this phenomenon are largely unknown to the general public in the Kinshasa region. The objective of this study is to find the causes leading to the disappearance of wild bee species in Kinshasa. Also, this research contributes to current knowledge of the biodiversity of wild bees in the Kinshasa region and helps the authorities to develop a good policy for the conservation or safeguarding of this biodiversity, which plays a key role in maintaining the integrity of our ecosystems. We carried out field surveys using interview sheets in the forest areas of Kinshasa where wild bees populated them. To achieve this, an interview sheet was made, and it included questions on the causes of the disappearance of wild bees and the destruction of forest areas. The interviews were carried out with the natives of these forest areas. The results of this study show us that the destruction of habitats or natural areas and the use of pesticides are the causes of the disappearance of these wild bees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wild%20bees" title="wild bees">wild bees</a>, <a href="https://publications.waset.org/abstracts/search?q=pollinisation" title=" pollinisation"> pollinisation</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=habitats" title=" habitats"> habitats</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=destruction" title=" destruction"> destruction</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide" title=" pesticide"> pesticide</a> </p> <a href="https://publications.waset.org/abstracts/157561/cause-of-the-disappearance-of-wild-bees-in-kinshasa-democratic-republic-of-congo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157561.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">99</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">80</span> Study the Behavior of Different Composite Short Columns (DST) with Prismatic Sections under Bending Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Sadeghi%20Balkanlou">V.

Several polymorphisms have been described in the human LEPR gene including p.K109R (rs1137100), p.Q223R (rs1137101) and p.K656N (rs1805094) polymorphisms. The role of these polymorphisms is not yet studied in Guadeloupian population. Our aim was to explore the association of LEPR polymorphisms (K109R, Q223R and K656N) with leptin levels and obesity in non-diabetic Afro-Caribbean subjects. Genotypic analysis of the three polymorphisms was performed in 425 subjects using TaqMan and KASPar Assays. Serum leptin was measured with ELISA kits Biovendor® (RD191001100). Logistic regressions were used for assessment of statistical associations. Mean age was 47.6 ± 12.7 years. Among the participants, 238 (56 %) were women, 124 (30%) were obese and 155 (36.5%) had abdominal obesity. Carriers of LEPR K656N rs1805094 rare allele had significant higher frequencies of obesity (P = 0.007), abdominal obesity (P = 0.004) and metabolic syndrome (P = 0.021) but mean leptin level was not significantly different between both groups (P = 0.075). Odds ratios, adjusted for age and sex associated with presence of rs1805094 rare allele were 1.8 (1.1-2.9), P = 0.012 for obesity, 2.0 (1.2-3.3), P = 0.008 for abdominal obesity and 1.8 (1.1-3.0), P = 0.031 for MetS. No significant association was found with K109R, Q223R. These findings suggest that the K656N polymorphism (but not the K109R or Q223R polymorphism) of LEPR is associated with obesity, abdominal obesity and metabolic syndrome in this Afro-Caribbean non-diabetic population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afro-Caribbean" title="Afro-Caribbean">Afro-Caribbean</a>, <a href="https://publications.waset.org/abstracts/search?q=leptin%20levels" title=" leptin levels"> leptin levels</a>, <a href="https://publications.waset.org/abstracts/search?q=leptin%20receptor%20gene%20polymorphisms" title=" leptin receptor gene polymorphisms"> leptin receptor gene polymorphisms</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/86912/obesity-leptin-levels-and-leptin-receptor-gene-polymorphisms-in-afro-caribbean-subjects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86912.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">382</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> Distributed Cyber Physical Secure Framework for DC Microgrids: DC Ship Power System Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grace%20karimi%20Muriithi">Grace karimi Muriithi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnaz%20Papari"> Behnaz Papari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Arsalan"> Ali Arsalan</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Shannon%20Edrington"> Christopher Shannon Edrington</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Complexity and nonlinearity of the control system design is increasing for DC microgrid applications when the cyber concept associated with the technology constraints will added to the picture.

The optimum condition with yield of 90.2% and exergy efficiency of 95.2% was obtained at methanol to oil molar ratio of 8:1, 1 wt.% of KOH, at 55 °C. In this condition, the total waste exergy was found to be 45.4 MJ for 1 kg biodiesel production. However high yield in the optimal condition resulted high exergy efficiency in the transesterification of WCO with methanol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy" title=" exergy"> exergy</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20analysis" title=" thermodynamic analysis"> thermodynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=transesterification" title=" transesterification"> transesterification</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20cooking%20oil" title=" waste cooking oil"> waste cooking oil</a> </p> <a href="https://publications.waset.org/abstracts/91280/exergy-an-effective-tool-to-quantify-sustainable-development-of-biodiesel-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91280.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">198</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> An Investigation of the Use of Visible Spectrophotometric Analysis of Lead in an Herbal Tea Supplement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salve%20Alessandria%20Alcantara">Salve Alessandria Alcantara</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Armand%20E.%20Aquino"> John Armand E.

Although sensitive analytical instruments are already available, the USP limit test for lead is still widely used. However, because of its serious shortcomings, Lang Lang and his colleagues developed a spectrophotometric method for determination of lead in all types of samples. This method was the one adapted in this study. The actual procedure performed was divided into three parts: digestion, extraction and analysis. For digestion, HNO3 and CH3COOH were used. Afterwards, masking agents, 0.003% and 0.001% dithizone in CHCl3 were added and used for the extraction. For the analysis, standard addition method and colorimetry were performed. This was done in triplicates under two conditions. The 1st condition, using 25µg/mL of standard, resulted to very low absorbances with an r2 of 0.551. This led to the use of a higher concentration, 1mg/mL, for condition 2. Precipitation of lead cyanide was observed and the absorbance readings were relatively higher but between 0.15-0.25, resulting to a very low r2 of 0.429. LOQ and LOD were not computed due to the limitations of the Milton-Roy Spectrophotometer. The method performed has a shorter digestion time, and used less but more accessible reagents. However, the optimum ratio of dithizone-lead complex must be observed in order to obtain reliable results while exploring other concentration of standards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=herbal%20tea%20supplement" title="herbal tea supplement">herbal tea supplement</a>, <a href="https://publications.waset.org/abstracts/search?q=lead-dithizone%20complex" title=" lead-dithizone complex"> lead-dithizone complex</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20addition" title=" standard addition"> standard addition</a>, <a href="https://publications.waset.org/abstracts/search?q=visible%20spectroscopy" title=" visible spectroscopy"> visible spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/10463/an-investigation-of-the-use-of-visible-spectrophotometric-analysis-of-lead-in-an-herbal-tea-supplement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10463.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">392</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> Wire Arc Additive Manufacturing of Aluminium–Magnesium Alloy AlMg4.5Mn With TiC Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javad%20Karimi">Javad Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The grain morphology and size of the additively manufactured (AM) aluminium alloys play a vital role in the performance and mechanical properties.

The biodiversity of tropical rainforests is undeniable, but many aspects remain poorly known, which directly influences its management. Despite the efforts of sustainable forest management, human pressure in terms of exploitation and smuggling of timber forms a problem compared to exploited species whose status is considered "vulnerable" on the IUCN red list compiled by. Commercial species in Class III of the Democratic Republic of Congo are the least known in the market operating, and their biology is unknown or non-existent. Identification of wood in terms of descriptions and anatomical measurements of the wood is in great demand for various stakeholders such as scientists, customs, IUCN, etc. The objective of this study is the qualitative and quantitative description of the anatomical characteristics of commercial species in Class III of DR Congo. The site of the Luki Biosphere Reserve was chosen because of its high tree species richness. This study focuses on the wood anatomy of 14 commercial species of Class III of DR Congo. Thirty-four wooden discs were collected for these species. The following parameters were measured in the field: Diameter at breast height (DBH), total height and geographic coordinates. Microtomy, identification of vessel parameters (diameter, density and grouping) and photograph of the microscopic sections and determining age were performed in this study. The results obtained are detailed anatomical descriptions of species in Class III of the Democratic Republic of Congo. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20management%20of%20forest" title="sustainable management of forest">sustainable management of forest</a>, <a href="https://publications.waset.org/abstracts/search?q=rainforest" title=" rainforest"> rainforest</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20species%20of%20class%20iii" title=" commercial species of class iii"> commercial species of class iii</a>, <a href="https://publications.waset.org/abstracts/search?q=vessel%20diameter" title=" vessel diameter"> vessel diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=vessel%20density" title=" vessel density"> vessel density</a>, <a href="https://publications.waset.org/abstracts/search?q=grouping%20vessel" title=" grouping vessel"> grouping vessel</a> </p> <a href="https://publications.waset.org/abstracts/144446/descriptive-study-of-tropical-tree-species-in-commercial-interest-biosphere-reserve-luki-in-the-democratic-republic-of-congo-drc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144446.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">219</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">63</span> Comparison of DPC and FOC Vector Control Strategies on Reducing Harmonics Caused by Nonlinear Load in the DFIG Wind Turbine </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Havasi">Hamid Havasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Reza%20Gholami%20Dehbalaei"> Mohamad Reza Gholami Dehbalaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Khorami"> Hamed Khorami</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahram%20Karimi"> Shahram Karimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamdi%20Abdi"> Hamdi Abdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Doubly-fed induction generator (DFIG) equipped with a power converter is an efficient tool for converting mechanical energy of a variable speed system to a fixed-frequency electrical grid.

They contribute to increase the economic burden. In case of emergence, rural populations are the most affected, hence the need to investigate risk practices in rural households of Penka-Michel (West Cameroon). Methods: This cross-sectional study was conducted from October to November 2021 among 200 heads of households living in the Penka-Michel health district (West Cameroon). It was done using a pre-tested and validated questionnaire, allowing to obtain socio-demographic, economic data, and data on zoonotic risk practices. Results: The participants [women (56%), men (44%)] worked mainly in the informal private sector (53%) and practiced agriculture secondarily (90%). Their highest level of education, for the most part, was a secondary school (50%); the average household size was 06 persons with a monthly income > 36270 FCFA (72%). 74% of household heads thought that animals can transmit diseases, and 17% had heard about zoonotic diseases through the media (65%). Rats caught in households (60%) were consumed there (74%), as was bush meat (61%) or dog meat (18%). For family food (90%), animals were slaughtered within the household (97%), rarely preceded by a veterinary inspection (6%). 87% of households practiced traditional rites with animal blood, 65% shared the same habitat as their animals, 41% did not systematically wash their hands after handling animals. More than 50% of households owned one or more dogs, usually strays (41%) and 48% of which were vaccinated (rabies). Many households had at least one: poultry (98%); pig (50%); dog (57%), cat (52%). 25% of households slaughtered sick animals for consumption, and 27% ate dead animals. Conclusion: This study identified numerous zoonotic risk practices in households in the Penka-Michel health district (West Cameroon). Concerted, multisectoral communication / awareness-raising actions are needed to break with these practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zoonoses" title="zoonoses">zoonoses</a>, <a href="https://publications.waset.org/abstracts/search?q=risky%20practices" title=" risky practices"> risky practices</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20households" title=" rural households"> rural households</a>, <a href="https://publications.waset.org/abstracts/search?q=penka-michel" title=" penka-michel"> penka-michel</a>, <a href="https://publications.waset.org/abstracts/search?q=cameroon" title=" cameroon"> cameroon</a> </p> <a href="https://publications.waset.org/abstracts/145267/zoonotic-risk-practices-in-rural-households-in-the-penka-michel-health-district-west-cameroon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145267.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">179</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">59</span> VANETs Geographic Routing Protocols: A survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Karimi">Ramin Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of common highly mobile wireless ad hoc networks is Vehicular Ad Hoc Networks. Hence routing in vehicular ad hoc network (VANET) has attracted much attention during the last few years. VANET is characterized by its high mobility of nodes and specific topology patterns. Moreover these networks encounter a significant loss rate and a very short duration of communication. In vehicular ad hoc networks, one of challenging is routing of data due to high speed mobility and changing topology of vehicles. Geographic routing protocols are becoming popular due to advancement and availability of GPS devices. Delay Tolerant Networks (DTNs) are a class of networks that enable communication where connectivity issues like sparse connectivity, intermittent connectivity; high latency, long delay, high error rates, asymmetric data rate, and even no end-to-end connectivity exist. In this paper, we review the existing Geographic Routing Protocols for VANETs and also provide a qualitative comparison of them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicular%20ad%20hoc%20networks" title="vehicular ad hoc networks">vehicular ad hoc networks</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20routing" title=" geographic routing"> geographic routing</a>, <a href="https://publications.waset.org/abstracts/search?q=delay%20tolerant%20networks" title=" delay tolerant networks"> delay tolerant networks</a> </p> <a href="https://publications.waset.org/abstracts/34821/vanets-geographic-routing-protocols-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34821.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">525</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">58</span> Mapping of Forest Cover Change in the Democratic Republic of the Congo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armand%20Okende">Armand Okende</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Beaumont"> Benjamin Beaumont</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Deforestation is a change in the structure and composition of flora and fauna, which leads to a loss of biodiversity, production of goods and services and an increase in fires. It concerns vast territories in tropical zones particularly; this is the case of the territory of Bolobo in the current province of Maï- Ndombe in the Democratic Republic of Congo. Indeed, through this study between 2001 and 2018, we believe that it was important to show and analyze quantitatively the important forests changes and analyze quantitatively. It’s the overall objective of this study because, in this area, we are witnessing significant deforestation. Methodology: Mapping and quantification are the methodological approaches that we have put forward to assess the deforestation or forest changes through satellite images or raster layers. These satellites data from Global Forest Watch are integrated into the GIS software (GRASS GIS and Quantum GIS) to represent the loss of forest cover that has occurred and the various changes recorded (e.g., forest gain) in the territory of Bolobo. Results: The results obtained show, in terms of quantifying deforestation for the periods 2001-2006, 2007-2012 and 2013-2018, the loss of forest area in hectares each year. The different change maps produced during different study periods mentioned above show that the loss of forest areas is gradually increasing. Conclusion: With this study, knowledge of forest management and protection is a challenge to ensure good management of forest resources. To do this, it is wise to carry out more studies that would optimize the monitoring of forests to guarantee the ecological and economic functions they provide in the Congo Basin, particularly in the Democratic Republic of Congo. In addition, the cartographic approach, coupled with the geographic information system and remote sensing proposed by Global Forest Watch using raster layers, provides interesting information to explain the loss of forest areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deforestation" title="deforestation">deforestation</a>, <a
