Objectives: Determine an epidemiological profile of patients with painful lumbar degenerative disc disease. Patients and methods: We performed a prospective study of 104 patients operated on for degenerative painful lumbar disc disease over a period of 25 months. The parameters analyzed were: age, sex, Body Mass Index (BMI), comorbidities, family history of low back pain, and difficulty with professional activity. Results: The average age was 43.3 years, with a clear predominance of men: 72 men for 32 women, the average BMI was 26.80Kg / m2, and 63.5% of the patients were overweight. The occurrence of disc degeneration in pathological conditions was noted in 14.4% of cases. The notion of familial low back pain was found in 49% of cases. The majority of patients perform more or less arduous work (51%) in the cases. Conclusion: In our series, degenerative painful lumbar disc disease predominates in the male subject, active obese who performs more or less painful work, in whom we find a family history of low back pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degenerative%20disc%20disease" title="degenerative disc disease">degenerative disc disease</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title=" low back pain"> low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20mass%20index" title=" body mass index"> body mass index</a>, <a href="https://publications.waset.org/abstracts/search?q=disque%20intervertebrale" title=" disque intervertebrale"> disque intervertebrale</a> </p> <a href="https://publications.waset.org/abstracts/155472/epidemiological-profile-of-patients-with-painful-degenerative-lumbar-disc-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155472.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">93</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">123</span> Lumbar Tuberculous Spondylitis in a Child Treated by Posterior Osteosynthesis: Apropos of a Case</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghoul%20Rachid%20Brahim">Ghoul Rachid Brahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Tuberculous spondylodiscitis is an infection of the spine by Mycobacterium tuberculosis. Tuberculous spondylodiscitis still remains a topical disease in developing countries and continues to pose a public health problem in endemic countries. Materials and methods: Clinical case: This is a 12-year-old child followed in pediatrics for weight loss and progressively worsening low back pain. The neurological examination found an irritative pyramidal syndrome in both lower limbs with a severe lumbar spinal syndrome. The radiological assessment: (Rx of the spine supplemented by CT and MRI) shows L1L2 spondylodiscitis. Treatment: The child is put on anti-tuberculosis treatment, and the spine is restrained with a corset. Control MRI shows a worsening of the dorsal kyphosis with a backward movement of the posterior wall and spinal cord compression. The child is operated on via the posterior approach (the operative procedure consists of an L1 laminectomy and D11 L3 osteosynthesis). Results: Spinal cord décompression and stabilization of the spine. Conclusion: Tuberculous spondylodiscitis in children remains a rare, aggressive, and progressive condition. The prognosis depends on the diagnosis's precocity and the therapeutic management quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tuberculous%20spondylodiscitis" title="tuberculous spondylodiscitis">tuberculous spondylodiscitis</a>, <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title=" mycobacterium tuberculosis"> mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=laminectomy" title=" laminectomy"> laminectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI" title=" MRI"> MRI</a> </p> <a href="https://publications.waset.org/abstracts/160342/lumbar-tuberculous-spondylitis-in-a-child-treated-by-posterior-osteosynthesis-apropos-of-a-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160342.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">91</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">122</span> Spinal Hydatidosis: Therapeutic Management of 5 Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghoul%20Rachid%20Brahim">Ghoul Rachid Brahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Trad%20Khodja%20Rafik"> Trad Khodja Rafik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vertebral localization of the hydatid cyst is a severe form of bone hydatidosis, is a parasitic infection caused by the larval forms of the tapeworms Echinococcus granulosus, The disease is slowly remaining silent (a long incubation period) which may explain why this pathology is often discovered at the stage of neurological complications. The objective of this study is to recall the clinical and radiological aspects of this condition and the importance of early diagnosis and appropriate management. We report a study of 5 patients with vertebral hydatidosis, four men and one woman, four (04) patients operated in the emergency setting for spinal cord compression (decompression by wide laminectomy with evacuation of intra and extra canal vesicles).Albendazole-based medical treatment is instituted in all patients. Results: The evolution was favorable for three patients, the other two patients reoperated for a local recurrence. Conclusion: Vertebral hydatidosis is a rare condition with a poor prognosis due to the risk of neurological damage, the infiltrating nature of bone lesions, the frequency of relapses and therapeutic difficulties. The only curative method remains surgery, which must aim for complete and large excision of the lesions as if it were a “malignant tumour”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydatidosis" title="hydatidosis">hydatidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Echinococcosis%20granulosus" title=" Echinococcosis granulosus"> Echinococcosis granulosus</a>, <a href="https://publications.waset.org/abstracts/search?q=hydatid%20cyst" title=" hydatid cyst"> hydatid cyst</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20compression" title=" spinal cord compression"> spinal cord compression</a>, <a href="https://publications.waset.org/abstracts/search?q=laminectomy" title=" laminectomy"> laminectomy</a> </p> <a href="https://publications.waset.org/abstracts/154755/spinal-hydatidosis-therapeutic-management-of-5-cases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154755.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">97</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">121</span> Place of Surgery in the Treatment of Painful Lumbar Degenerative Disc Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghoul%20Rachid%20Brahim">Ghoul Rachid Brahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Back pain is a real public health problem with a significant socio-economic impact. It is the consequence of a degeneration of the lumbar intervertebral disc (IVD). This often asymptomatic pathology is compatible with an active life. As soon as it becomes symptomatic, conservative treatment is recommended in the majority of cases. The physical or functional disability is resistant to well-monitored conservative treatment, which justifies a surgical alternative which imposes a well-studied reflection on the objectives to be achieved. Objective: Evaluate the indication and short and medium term contribution of surgery in the management of painful degenerative lumbar disc disease. To prove the effectiveness of surgical treatment in the management of painful lumbar degenerative disc disease. Materials and methods: This is a prospective descriptive mono-centric study without comparison group, comprising a series of 104 patients suffering from lumbar painful degenerative disc disease treated surgically. Retrospective analysis of data collected prospectively. Comparison between pre and postoperative clinical status, by pain self-assessment scores and on the impact on pre and postoperative quality of life (3, 6 to 12 months). Results: This study showed that patients who received surgical treatment had great improvements in symptoms, function and several health-related quality of life in the first year after surgery. Conclusions: The surgery had a significantly positive impact on patients' pain, disability and quality of life. Overall, 97% of the patients were satisfied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degenerative%20disc%20disease" title="degenerative disc disease">degenerative disc disease</a>, <a href="https://publications.waset.org/abstracts/search?q=intervertebral%20disc" title=" intervertebral disc"> intervertebral disc</a>, <a href="https://publications.waset.org/abstracts/search?q=several%20health-related%20quality" title=" several health-related quality"> several health-related quality</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20painful" title=" lumbar painful"> lumbar painful</a> </p> <a href="https://publications.waset.org/abstracts/155465/place-of-surgery-in-the-treatment-of-painful-lumbar-degenerative-disc-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155465.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">120</span> Systems Versioning: A Features-Based Meta-Modeling Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ola%20A.%20Younis">Ola A.

Controlling these versions and tracking their changes became a very hard process as some versions are created using meaningless names or specifications. Many versions of a system are created with no clear difference between them. This leads to mismatching between a user’s request and the version he gets. In this paper, we present a system versions meta-modeling approach that produces versions based on system’s features. This model reduced the number of steps needed to configure a release and gave each version its unique specifications. This approach is applicable for systems that use features in its specification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=features" title="features">features</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-modeling" title=" meta-modeling"> meta-modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20modeling" title=" semantic modeling"> semantic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=SPL" title=" SPL"> SPL</a>, <a href="https://publications.waset.org/abstracts/search?q=VCS" title=" VCS"> VCS</a>, <a href="https://publications.waset.org/abstracts/search?q=versioning" title=" versioning"> versioning</a> </p> <a href="https://publications.waset.org/abstracts/7797/systems-versioning-a-features-based-meta-modeling-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7797.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">446</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">119</span> Sliding Mode Control of an Internet Teleoperated PUMA 600 Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdallah%20Ghoul">Abdallah Ghoul</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Ouamri"> Bachir Ouamri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Khalil%20Bousserhane"> Ismail Khalil Bousserhane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we have developed a sliding mode controller for PUMA 600 manipulator robot, to control the remote robot a teleoperation system was developed.

Using this procedure, ten patients underwent this procedure with excellent aesthetic results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cranioplasty" title="cranioplasty">cranioplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=cranial%20defect" title=" cranial defect"> cranial defect</a>, <a href="https://publications.waset.org/abstracts/search?q=PMMA" title=" PMMA"> PMMA</a>, <a href="https://publications.waset.org/abstracts/search?q=3d%20printing" title=" 3d printing"> 3d printing</a>, <a href="https://publications.waset.org/abstracts/search?q=custom%20made%20implants" title=" custom made implants"> custom made implants</a> </p> <a href="https://publications.waset.org/abstracts/185468/cranioplasty-with-custom-implant-realized-using-3d-printing-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185468.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">56</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> Integrative Transcriptomic Profiling of NK Cells and Monocytes: Advancing Diagnostic and Therapeutic Strategies for COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salma%20Loukman">Salma Loukman</a>, <a href="https://publications.waset.org/abstracts/search?q=Reda%20Benmrid"> Reda Benmrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Najat%20Bouchmaa"> Najat Bouchmaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hicham%20Hboub"> Hicham Hboub</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20El%20Fatimy"> Rachid El Fatimy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Benhida"> Rachid Benhida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, it use integrated transcriptomic datasets from the GEO repository with the purpose of investigating immune dysregulation in COVID-19. Thus, in this context, we decided to be focused on NK cells and CD14+ monocytes gene expression, considering datasets GSE165461 and GSE198256, respectively. Other datasets with PBMCs, lung, olfactory, and sensory epithelium and lymph were used to provide robust validation for our results. This approach gave an integrated view of the immune responses in COVID-19, pointing out a set of potential biomarkers and therapeutic targets with special regard to standards of physiological conditions. IFI27, MKI67, CENPF, MBP, HBA2, TMEM158, THBD, HBA1, LHFPL2, SLA, and AC104564.3 were identified as key genes from our analysis that have critical biological processes related to inflammation, immune regulation, oxidative stress, and metabolic processes. Consequently, such processes are important in understanding the heterogeneous clinical manifestations of COVID-19—from acute to long-term effects now known as 'long COVID'. Subsequent validation with additional datasets consolidated these genes as robust biomarkers with an important role in the diagnosis of COVID-19 and the prediction of its severity. Moreover, their enrichment in key pathophysiological pathways presented them as potential targets for therapeutic intervention.The results provide insight into the molecular dynamics of COVID-19 caused by cells such as NK cells and other monocytes. Thus, this study constitutes a solid basis for targeted diagnostic and therapeutic development and makes relevant contributions to ongoing research efforts toward better management and mitigation of the pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SARS-COV-2" title="SARS-COV-2">SARS-COV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA-seq" title=" RNA-seq"> RNA-seq</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=severity" title=" severity"> severity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20COVID-19" title=" long COVID-19"> long COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20analysis" title=" bio analysis"> bio analysis</a> </p> <a href="https://publications.waset.org/abstracts/193566/integrative-transcriptomic-profiling-of-nk-cells-and-monocytes-advancing-diagnostic-and-therapeutic-strategies-for-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193566.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">12</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">116</span> Modeling of Leaks Effects on Transient Dispersed Bubbly Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Kessal">Mohand Kessal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Boucetta"> Rachid Boucetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Tikobaini"> Mourad Tikobaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Zamoum"> Mohammed Zamoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leakage problem of two-component fluids flow is modeled for a transient one-dimensional homogeneous bubbly flow and developed by taking into account the effect of a leak located at the middle point of the pipeline.

This study aimed to investigate the insecticidal potential of six aqueous (100% water), and methanolic (20/80 (v/v) MeOH/H2O) extracts obtained from aromatic and medicinal plants growing in arid and semi-arid regions of Morocco to control nymphs and adult females of D. opuntiae, under laboratory and greenhouse conditions. Under laboratory conditions, the aqueous extracts of Atriplex halimus at 5% caused significant mortality in nymphs with 71% four days after application and 88%on adult females of D. opuntiae8 days post-treatment. Under greenhouse conditions, the aqueous extract of A. halimus combined with black soap at 10 g/L showed the highest mortality rate of nymphs with 100%, 4 days after application. The adult females' mortality increased significantly to reach 83.75%,14 days after the second application of A. halimus aqueous extract at 5%. Phytochemical analysis of the water extract of A. halimus revealed a high content of saponins (24.09 ± 0.71 mg SSE/g DW) compared to other plant extracts, which was confirmed by LC-MS characterization that showed the presence of 36 triterpenoid saponin compounds (derived from oleic-12-en-28-oic acid), in addition to phytoecdysones, simple carboxylic acids, and flavonoids. These findings showed that using the aqueous extract of A. halimus as a biological pesticide could be incorporated into the management package to control the wild cochineal as a safe alternative to chemical insecticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dactylopius%20opuntiae" title="dactylopius opuntiae">dactylopius opuntiae</a>, <a href="https://publications.waset.org/abstracts/search?q=opuntia%20ficus-indica%20L." title=" opuntia ficus-indica L."> opuntia ficus-indica L.</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20extracts" title=" plant extracts"> plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=atriplex%20halimus" title=" atriplex halimus"> atriplex halimus</a>, <a href="https://publications.waset.org/abstracts/search?q=saponins" title=" saponins"> saponins</a> </p> <a href="https://publications.waset.org/abstracts/150439/chemical-composition-and-insecticidal-properties-of-moroccan-plant-extracts-against-dactylopius-opuntiae-cockerell-under-laboratory-and-greenhouse-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150439.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">145</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">113</span> Physicochemical Characterizations of Marine and River Sediments in the North of France</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abriak%20Nor%20Edine">Abriak Nor Edine</a>, <a href="https://publications.waset.org/abstracts/search?q=Zentar%20Rachid"> Zentar Rachid</a>, <a href="https://publications.waset.org/abstracts/search?q=Achour%20Raouf"> Achour Raouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Ngoc%20Thanh"> Tran Ngoc Thanh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is undertaken to develop a methodology to enhance the management of dredged marine and river sediments in the North of France.

These were noteworthy results when compared to an unheated witness greenhouse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20system" title="solar system">solar system</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20greenhouse" title=" agricultural greenhouse"> agricultural greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=heating" title=" heating"> heating</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a> </p> <a href="https://publications.waset.org/abstracts/189034/assessment-of-the-thermal-performance-of-a-solar-heating-system-on-an-agricultural-greenhouse-microclimate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189034.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">25</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">107</span> Impact of aSolar System Designed to Improve the Microclimate of an Agricultural Greenhouse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Arbaoui">Nora Arbaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Tadili"> Rachid Tadili</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilham%20Ihoume"> Ilham Ihoume</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The improvement of the agricultural production and food preservation processes requires the introduction of heating and cooling techniques in greenhouses. To develop these techniques, our work proposes a design of an integrated and autonomous solar system for heating, cooling, and production conservation in greenhouses. The hot air produced by the greenhouse effect during the day will be evacuated to compartments annexed in the greenhouse to dry the surplus agricultural production that is not sold on the market.

However, it presents a problem of field linkage and torque ripple. In order to solve this problem, the conventional DTC is combined with space vector pulse width modulation (SVPWM). This control theory has achieved great success in the control of PMSM. That has become a hotspot for resolving. The main objective of this paper gives us an introduction of the DTC and SVPWM-DTC control theory of PMSM which has been simulating on each part of the system via Matlab/Simulink based on the mathematical modeling. Moreover, the outcome of the simulation proved that the improved SVPWM- DTC of PMSM has a good dynamic and static performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PMSM" title="PMSM">PMSM</a>, <a href="https://publications.waset.org/abstracts/search?q=DTC" title=" DTC"> DTC</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM" title=" SVM"> SVM</a>, <a href="https://publications.waset.org/abstracts/search?q=speed%20control" title=" speed control"> speed control</a> </p> <a href="https://publications.waset.org/abstracts/43513/svm-dtc-using-for-pmsm-speed-tracking-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43513.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">389</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">104</span> A Study of Traffic Assignment Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelfetah%20Laouzai">Abdelfetah Laouzai</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Ouafi"> Rachid Ouafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a traffic network, users usually choose their way so that it reduces their travel time between pairs origin-destination. This behavior might seem selfish as it produces congestions in different parts of the network. The traffic assignment problem (TAP) models the interactions between congestion and user travel decisions to obtain vehicles flows over each axis of the traffic network. The resolution methods of TAP serve as a tool allows predicting users’ distribution, identifying congesting points and affecting the travelers’ behavior in the choice of their route in the network following dynamic data. In this article, we will present a review about specific resolution approach of TAP.

The dependence of manufacturing parameters on the quality of the chemical treatment was confirmed. The aim of this work is to improve the properties of the fabric through the development of manufacturing technology appropriately.

It is a malignant tumor usually developed at the expense of the salivary glands; its orbital location is exceptional. It is a rare clinical entity, formidable by its malignancy and local aggressiveness; the recurrence rate is high. Materials and methods: Clinical case: 63 years old woman who presents with irreducible no pulsatile painful left exophthalmos with inflammatory chemosis and a decrease in visual acuity with a moderate intracranial hypertension syndrome that has been evolving for 03 months. Antecedent; a biopsy of the tumor was made; the histological examination was in favor of an adenoid cystic carcinoma of the lacrimal gland. Lesion assessment: computed tomography and brain MRI: show an intra and extra-conical mass; with sinus (ethmoido-frontal) and cerebral (left frontal) extension strongly enhanced after injection of contrast product surrounded by edema around the lesion, associated with left frontal bone lysis extension assessment: unremarkable treatment: Patient operated by left frontotemporal approach, a total exenteration was performed with macroscopically complete excision of the frontal lesion and wide frontal craniectomy with craniofacial reconstruction, followed by complementary radiotherapy. Results: The patient was seen again after 3 months in consultation; she does not present any signs in favor of a recurrence. Conclusion: Adenoid cystic carcinomas of the lacrimal gland are rare malignant tumors; they are very infiltrating and invasive. The prognosis is strongly linked to the treatment time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adenoid%20cystic" title="adenoid cystic">adenoid cystic</a>, <a href="https://publications.waset.org/abstracts/search?q=lacrimal%20gland" title=" lacrimal gland"> lacrimal gland</a>, <a href="https://publications.waset.org/abstracts/search?q=orbital%20location" title=" orbital location"> orbital location</a>, <a href="https://publications.waset.org/abstracts/search?q=fronto-temporal%20approac" title=" fronto-temporal approac"> fronto-temporal approac</a> </p> <a href="https://publications.waset.org/abstracts/155891/adenoid-cystic-carcinoma-of-the-lacrimal-gland-about-a-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155891.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">71</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">100</span> A Comparative Analysis of Multicarrier SPWM Strategies for Five-Level Flying Capacitor Inverter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Belmadani">Bachir Belmadani</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Taleb"> Rachid Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinelaabidine%20Boudjema"> Zinelaabidine Boudjema</a>, <a href="https://publications.waset.org/abstracts/search?q=Adil%20Yahdou"> Adil Yahdou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carrier-based methods have been used widely for switching of multilevel inverters due to their simplicity, flexibility and reduced computational requirements compared to space vector modulation (SVM).

The simulation results using Matlab / Simulink demonstrate the efficiency and performance of the proposed technique while maintaining the simplicity of control by first order sliding mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correction%20of%20the%20equivalent%20command" title="correction of the equivalent command">correction of the equivalent command</a>, <a href="https://publications.waset.org/abstracts/search?q=DFIG" title=" DFIG"> DFIG</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20machine" title=" induction machine"> induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20controller" title=" sliding mode controller"> sliding mode controller</a> </p> <a href="https://publications.waset.org/abstracts/63503/sliding-mode-control-of-the-power-of-doubly-fed-induction-generator-for-variable-speed-wind-energy-conversion-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63503.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">96</span> Optimum Design of Photovoltaic Water Pumping System Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Abdourraziq">Sarah Abdourraziq</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20El%20Bachtiri"> Rachid El Bachtiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The solar power source for pumping water is one of the most promising areas in photovoltaic applications. The implementation of these systems allows to protect the environment and reduce the CO<sub>2</sub> gas emission compared to systems trained by diesel generators. This paper presents a comparative study between the photovoltaic pumping system driven by DC motor, and AC motor to define the optimum design of this application. The studied system consists of PV array, DC-DC Boost Converter, inverter, motor-pump set and storage tank. The comparison was carried out to define the characteristics and the performance of each system. Each subsystem is modeled in order to simulate the whole system in MATLAB/ Simulink. The results show the efficiency of the proposed technique. <p class="card-text"><strong>Keywords:</strong> <a
