This paper presents a control strategy for an underactuated six degrees of freedom (6 DOF) trirotor helicopter, based on the coupling of the fuzzy logic control and sliding mode control (SMC). The main purpose of this work is to eliminate the chattering phenomenon. To achieve our purpose we have used a fuzzy logic control to generate the hitting control signal, also the non linear observer is then synthesized in order to estimate the unmeasured states. Finally simulation results are included to indicate the trirotor UAV with the proposed controller can greatly alleviate the chattering effect and remain robust to the external disturbances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20sliding%20mode%20control" title="fuzzy sliding mode control">fuzzy sliding mode control</a>, <a href="https://publications.waset.org/abstracts/search?q=trirotor%20helicopter" title=" trirotor helicopter"> trirotor helicopter</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20modelling" title=" dynamic modelling"> dynamic modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=underactuated%20systems" title=" underactuated systems "> underactuated systems </a> </p> <a href="https://publications.waset.org/abstracts/21720/design-of-a-sliding-mode-control-using-nonlinear-sliding-surface-and-nonlinear-observer-applied-to-the-trirotor-mini-aircraft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21720.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">534</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">118</span> Composition and Distribution of Seabed Marine Litter Along Algerian Coast (Western Mediterranean)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Inal">Ahmed Inal</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Rouidi"> Samir Rouidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Bachouche"> Samir Bachouche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study is focused on the distribution and composition of seafloor marine litter associated to trawlable fishing areas along Algerian coast. The sampling was done with a GOC73 bottom trawl during four (04) demersal resource assessment cruises, respectively, in 2016, 2019, 2021 and 2022, carried out on board BELKACEM GRINE R/V. A total of 254 fishing hauls were sampled for the assessment of marine litter. Hauls were performed between 22 and 600 m of depth, the duration was between 30 and 60 min. All sampling was conducted during daylight. After the haul, marine litter was sorted and split from the catch. Then, according to the basis of the MEDITS protocol, litters were sorted into six different categories (plastic, rubber, metal, wood, glass and natural fiber). Thereafter, all marine litter were counted and weighed separately to the nearest 0.5 g. The results shows that the maximums of marine litter densities in the seafloor of the trawling fishing areas along Algerian coast are, respectively, 1996 item/km2 in 2016, 5164 item/km2 in 2019, 2173 item/km2 in 2021 and 7319 item/km2 in 2022. Thus, the plastic is the most abundant litter, it represent, respectively, 46% of marine litter in 2016, 67% in 2019, 69% in 2021 and 74% in 2022. Regarding the weight of the marine litter, it varies between 0.00 and 103 kg in 2016, between 0.04 and 81 kg in 2019, between 0.00 and 68 Kg in 2021 and between 0.00 and 318 kg in 2022. Thus, the maximum rate of marine litter compared to the total catch approximate, respectively, 66% in 2016, 90% in 2019, 65% in 2021 and 91% in 2022. In fact, the average loss in catch is estimated, respectively, at 7.4% in 2016, 8.4% in 2019, 5.7% in 2021 and 6.4% in 2022. However, the bathymetric and geographical variability had a significant impact on both density and weight of marine litter. Marine litter monitoring program is necessary for offering more solution proposals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composition" title="composition">composition</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=seabed" title=" seabed"> seabed</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20litter" title=" marine litter"> marine litter</a>, <a href="https://publications.waset.org/abstracts/search?q=algerian%20coast" title=" algerian coast"> algerian coast</a> </p> <a href="https://publications.waset.org/abstracts/176734/composition-and-distribution-of-seabed-marine-litter-along-algerian-coast-western-mediterranean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176734.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">68</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">117</span> Study of Quantum Lasers of Random Trimer Barrier AlxGa1-xAs Superlattices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bentata%20Samir">Bentata Samir</a>, <a href="https://publications.waset.org/abstracts/search?q=Bendahma%20Fatima"> Bendahma Fatima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have numerically studied the random trimer barrier AlxGa1-xAs superlattices (RTBSL).

Thus, the article relates to one of the main cultural pillars of the literary heritage. Creative individuals within the framework of this type of “Adab” have viewed the rulers as the ultimate goal they try to reach in their classification efforts, with the aim of educating, entertaining and amusing.

At maximum radiation dose of 209.3 kGy 91.38% of TCB has converted into different organic compounds, such as 1,4-, 1,3- and 1,2- dichlorobenzenes (DCB), chlorobenzene, toluene, benzene and other chlorinated and non-chlorinated compounds. The variation of compounds formed by γ-radiolysis depends on the nature of solvent and radiation dose. One of the frequently identified radiolysis products of TCB in different organic solvents - 1,4-DCB studied quantitatively with external standard. The concentration of DCB increases by increasing absorbed radiation dose to approximately 131.8 kGy, then at higher doses with its conversion into chlorobenzene, it decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B3-radiolysis" title="γ-radiolysis">γ-radiolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorinated%20pesticides" title=" chlorinated pesticides"> chlorinated pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20dose" title=" radiation dose"> radiation dose</a>, <a href="https://publications.waset.org/abstracts/search?q=dechlorination" title=" dechlorination"> dechlorination</a> </p> <a href="https://publications.waset.org/abstracts/155160/the-study-of-gh-radiolysis-of-124-trichlorobenzene-in-methanol-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155160.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">111</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">110</span> Ballistic Transport in One-Dimensional Random Dimer Photonic Crystals </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Cherid">Samira Cherid</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Bentata"> Samir Bentata</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20Zahira%20Meghoufel"> F.

However, tuning suitably the defect dimer resonance on the host ones (or vice versa), the transmission magnitudes can be enhanced providing the optimized ballistic transmission regime as an average response.

Aim: To compare TE and liver biopsy in hepatitis C virus (HCV) patients, genotype IV and evaluate the effect of steatosis and schistosomiasis on FibroScan. Methods: The fibrosis stage (METAVIR Score) TE, was assessed in 519 patients. The diagnostic performance of FibroScan is assessed by calculating the area under the receiver operating characteristic curves (AUROCs). Results: The cut-off value of ≥ F2 was 8.55 kPa, ≥ F3 was 10.2 kPa and cirrhosis = F4 was 16.3 kPa.

To carry out this delicate mission, which requires reconciling often contradictory objectives, the auditor is called upon, who must be able to express an opinion on the effectiveness of the operation of the "production" function. To do this, the auditor must structure his mission in three phases, namely, the preparation phase to assimilate the particularities of this function, the implementation phase and the conclusion phase. The audit is a systematic and independent examination of all the stages of a manufacturing process intended to determine whether the pre-established arrangements for the combination of production factors are respected, whether their implementation is effective and whether they are relevant in relation to the goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit" title="audit">audit</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20of%20process" title=" performance of process"> performance of process</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20examination" title=" independent examination"> independent examination</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20tools" title=" management tools"> management tools</a>, <a href="https://publications.waset.org/abstracts/search?q=audit%20of%20accounts" title=" audit of accounts"> audit of accounts</a> </p> <a href="https://publications.waset.org/abstracts/168614/audit-is-a-production-performance-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168614.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">75</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">99</span> A Model-Driven Approach of User Interface for MVP Rich Internet Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Roubi">Sarra Roubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Erramdani"> Mohammed Erramdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Mbarki"> Samir Mbarki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an approach for the model-driven generating of Rich Internet Application (RIA) focusing on the graphical aspect.

The most significant feature of any superconductor, from the viewpoint of uses, is the maximum electrical transport current density that this superconductor is capable of withstanding without loss of energy. In this work, vortices pinning in conventional and high-TC superconductors will be studied. Our experiments on vortices pinning in single crystals and nanoparticles of YBa2Cu3O7- and La1.85 Sr0.15CuO will be presented. It will be given special attention to the study of the YBa2Cu3O7- nanoparticles doped by ferromagnetic nanoparticles of Y3Fe5O12.

In the context of macroscopic poroelastoplasticity, the hydromechanical coupling between the skeleton deformation and the fluid pressure is addressed by means of two constitutive equations. The first state equation relates the stress to skeleton strain and pore pressure, while the second state equation relates the Lagrangian porosity change to skeleton volume strain and pore pressure. A specific algorithm for local plastic integration using a tangent operator is devised. A modified Cam-clay type yield surface with associated plastic flow rule is adopted to account for both contractive and dilative behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=poromechanics" title=" poromechanics"> poromechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=poroplasticity" title=" poroplasticity"> poroplasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20analysis" title=" reservoir analysis"> reservoir analysis</a> </p> <a href="https://publications.waset.org/abstracts/65748/a-parallel-poromechanics-finite-element-method-fem-model-for-reservoir-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65748.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">391</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">94</span> A Novel Method For Non-Invasive Diagnosis Of Hepatitis C Virus Using Electromagnetic Signal Detection: A Multicenter International Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gamal%20Shiha">Gamal Shiha</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Samir"> Waleed Samir</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Azam"> Zahid Azam</a>, <a href="https://publications.waset.org/abstracts/search?q=Premashis%20Kar"> Premashis Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Hamid"> Saeed Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiv%20Sarin"> Shiv Sarin </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple, rapid and non-invasive electromagnetic sensor (C-FAST device) was- patented; for diagnosis of HCV RNA.

The major constituents of the olive pulp are husks and seeds. The separation of each portion of olive pulp (seeds and husks) was carried out by water flotation where seeds were sediment in the bottom. Both seeds and husks were dignified by 15% NaOH followed by complete lignin removal by using sodium chlorite in acidic medium. The isolated holocellulose, α-cellulose, hydrogel and CMC which prepared from cellulose of both seeds and husk fractions were characterized by FTIR and SEM. The present study focused on the investigation of the chemical components of the lignocellulosic fraction of olive pulp.

The model is intended to describe the velocity profile and to predict the fiber orientation. The flow was considered to be incompressible, and behave as Newtonian fluid containing suspensions of short-fibers. The numerical model for determination of velocity profile and fiber orientation during mold-filling stage of injection molding process was solved using finite volume method. The governing equations of this problem are: the continuity, the momentum and the energy. The obtained results were compared to available experimental findings. A good agreement between the numerical results and the experimental data was achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=injection" title="injection">injection</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=short-fiber%20reinforced%20thermoplastics" title=" short-fiber reinforced thermoplastics"> short-fiber reinforced thermoplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20orientation" title=" fiber orientation"> fiber orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=incompressible%20fluid" title=" incompressible fluid"> incompressible fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/5968/modeling-study-of-short-fiber-orientation-in-simple-injection-molding-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5968.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">465</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">91</span> Studying the Intercalation of Low Density Polyethylene/Clay Nanocomposites after Different UV Exposures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Al-Zobaidi">Samir Al-Zobaidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study attempts to understand the effect of different UV irradiation methods on the intercalation of LDPE/MMT nanocomposites, and its molecular behavior at certain isothermal crystallization temperature. Three different methods of UV exposure were employed using single composition of LDPE/MMT nanocomposites. All samples were annealed for 5 hours at a crystallization temperature of 100°C. The crystallization temperature was chosen to be at large supercooling temperature to ensure quick and complete crystallization. The raw material of LDPE consisted of two stable monoclinic and orthorhombic phases according to XRD results. The thermal behavior of both phases acted differently when UV exposure method was changed. The monoclinic phase was more dependent on the method used compared to the orthorhombic phase. The intercalation of clay, as well as, the non-isothermal crystallization temperature, has also shown a clear dependency on the type of UV exposure. A third phase that is thermally less stable was also observed. Its respond to UV irradiation was greater since it contains low molecular weight entities which make it more vulnerable to any UV exposure. <p class="card-text"><strong>Keywords:</strong> <a
