Swan neck deformity is not very common in finger it may occur after any disease. Conservative treatment of the swan neck deformity is available by using different static splints only. There are very few reports of surgical correction of swan-neck deformity in benign hypermobility syndrome. Method: This case report describes the result of surgical intervention and hand splint in a twenty year old lady with past history of cardiovascular stroke with no residual neurological deficit. She presented with correctable swan neck deformity and failed to improve with static ring splints to correct the deformity. She was noted to have hyperlaxity (EhlerDanlos type) as per modified Beighton’s score of 5/9. She underwent volar plate plication of the proximal interphalangeal joint of the left ring finger along with hemitenodesis of ulnar slip of flexor digitorum superficialis (FDS) tendon whereby, the ulnar slip of FDS was passed through a small surgically created rent in A2 pulley and sutured back to itself. Result: Postoperatively, the patient was referred to occupational therapy for splinting with the instruction that the splint would work some time for as static and some time as dynamic for positional and correction of the finger. Conclusion: After occupational therapy intervention and splinting, the patient had a full correction of the swan-neck deformity with near full flexion of the operated finger and is able to work independently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swan%20neck" title="swan neck">swan neck</a>, <a href="https://publications.waset.org/abstracts/search?q=finger" title=" finger"> finger</a>, <a href="https://publications.waset.org/abstracts/search?q=deformity" title=" deformity"> deformity</a>, <a href="https://publications.waset.org/abstracts/search?q=splint" title=" splint"> splint</a>, <a href="https://publications.waset.org/abstracts/search?q=hypermobility" title=" hypermobility"> hypermobility</a> </p> <a href="https://publications.waset.org/abstracts/64592/a-surgical-correction-and-innovative-splint-for-swan-neck-deformity-in-hypermobility-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64592.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">254</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">515</span> Botulinum Toxin type A for Lower Limb Lengthening and Deformity Correction: A Systematic Review and Meta-analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jawaher%20F.%20Alsharef">Jawaher F.

Lately, BTX-A injection received great interest as a part of multimodal pain management for lower limb lengthening and deformity correction. This systematic review aimed to determine the role of BTX-A injection in pain management for during lower limb lengthening and/or deformity correction. We searched Medline, Embase, and CENTRAL. We included randomized controlled trials (RCTs) that compared the BTX-A injection to placebo for individuals undergoing lower limb lengthening and/or deformity correction. We sought to evaluate the following outcomes: pain on visual analogue scale (VAS), range of motion parameters, average opioid consumption, and adverse events. The standardized mean difference (SMD) was used to represent continuous outcomes while risk ratio (RR) was used to represent dichotomous outcomes. A total of 4 RCTs that enrolled 257 participants (337 limbs) deemed eligible. Adjuvant BTX-A injection showed a significant reduction in post-operative pain compared to placebo (SMD=–0.28, 95% CI –0.53 to –0.04). No difference was found between BTX-A injection and placebo in terms of range of motion parameters, average opioid consumption, or adverse events after surgical limb lengthening and/or deformity correction (RR= 0.77, 95% CI –0.58 to 1.03). Conclusions: Adjuvant BTX-A injection conferred a discernible reduction in post-operative pain during surgical limb lengthening and/or deformity without increasing the risk of adverse events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=botulinum%20toxin%20type%20A" title="botulinum toxin type A">botulinum toxin type A</a>, <a href="https://publications.waset.org/abstracts/search?q=limb%20lengthening" title=" limb lengthening"> limb lengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=distraction%20osteogenesis" title=" distraction osteogenesis"> distraction osteogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=deformity%20correction" title=" deformity correction"> deformity correction</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20management" title=" pain management"> pain management</a> </p> <a href="https://publications.waset.org/abstracts/151436/botulinum-toxin-type-a-for-lower-limb-lengthening-and-deformity-correction-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151436.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">142</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">514</span> Correction of Skeletal Deformity by Surgical Approach – A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davender%20Kumar">Davender Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Virender%20Singh"> Virender Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rekha%20Sharma"> Rekha Sharma </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Correction of skeletal deformities in adult patients with orthodontics is limited.

A LabVIEW program has been developed to evaluate the moiré pictures of patients with Scheuermann disease. Two different solutions were tested in this computer program, the extreme and the inflexion point calculation methods. Effects using these methods were compared and according to the results both solutions seemed to be appropriate.

The currently propagated techniques for treating a scaphoid non-union in children are either the operative reconstruction of the scaphoid or the conservative treatment with splinting in a scaphoid cast. Cases: In the first case, we operated on a 13 years old male patient with a posttraumatic scaphoid non-union in the middle third with a humpback deformity. We resected the middle third of the scaphoid and grafted the defect with an iliac crest bone, and the DISI-Deformity was reduced. Fixation was performed with K-Wires and immobilisation in a scaphoid cast. In the second case a 13 years old male patient also with a posttraumatic scaphoid non-union in the middle third and humpback deformity, DISI-deformity, was treated conservatively. Immobilisation in a scaphoid cast for four months was performed. Results: Operative: One year postoperatively the patient achieved a painless free arc of motion. Flexion/Extension 70/0/60°, Radial-/Ulnarduction 30/0/30° and Pro-/Supination 90/0/90°. The computer tomogram showed complete consolidation and bony fusion of the iliac crest bone. Conservative: Six to eight months after conservative treatment the patient demonstrated painless motion and AROM Flexion/Extension 80/0/80°, Radial-/Ulnarduction and Pro-/Supination in maximum range. Complete consolidation in the computer tomogram with persistent humpback- and DISI deformity. Conclusion: In the literature, both techniques are described, either the operative scaphoid reconstruction or the conservative treatment with splinting. In our cases, both the operative and conservative treatments showed comparable good results. However, the humpback- and DISI deformity can only be addressed with a surgical approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scaphoid" title="scaphoid">scaphoid</a>, <a href="https://publications.waset.org/abstracts/search?q=non-union" title=" non-union"> non-union</a>, <a href="https://publications.waset.org/abstracts/search?q=trauma" title=" trauma"> trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=operative%20vs.%20non%20operative" title=" operative vs. non operative"> operative vs. non operative</a> </p> <a href="https://publications.waset.org/abstracts/161069/operative-versus-non-operative-treatment-of-scaphoid-non-union-in-children-a-case-presentation-and-review-of-the-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161069.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">74</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">511</span> MCERTL: Mutation-Based Correction Engine for Register-Transfer Level Designs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Salah">Khaled Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present MCERTL (mutation-based correction engine for RTL designs) as an automatic error correction technique based on mutation analysis. A mutation-based correction methodology is proposed to automatically fix the erroneous RTL designs. The proposed strategy combines the processes of mutation and assertion-based localization. The erroneous statements are mutated to produce possible fixes for the failed RTL code. A concurrent mutation engine is proposed to mitigate the computational cost of running sequential mutants operators. The proposed methodology is evaluated against some benchmarks. The experimental results demonstrate that our proposed method enables us to automatically locate and correct multiple bugs at reasonable time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bug%20localization" title="bug localization">bug localization</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction" title=" error correction"> error correction</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation" title=" mutation"> mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=mutants" title=" mutants"> mutants</a> </p> <a href="https://publications.waset.org/abstracts/80068/mcertl-mutation-based-correction-engine-for-register-transfer-level-designs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80068.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">280</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">510</span> A Single Stage Cleft Rhinoplasty Technique for Primary Unilateral Cleft Lip and Palate 'The Gujrat Technique'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diaa%20Othman">Diaa Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Adil%20Khan"> Muhammad Adil Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Riaz"> Muhammad Riaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Without an early intervention to correct the unilateral complete cleft lip and palate deformity, nasal architecture can progress to an exaggerated cleft nose deformity. We present the results of a modified unilateral cleft rhinoplasty procedure ‘the Gujrat technique’ to correct this deformity. Ninety pediatric and adult patients with non-syndromic unilateral cleft lip underwent primary and secondary composite cleft rhinoplasty using the Gujrat technique as a single stage operation over a 10-year period. The technique involved an open rhinoplasty with Tennison lip repair, and employed a combination of three autologous cartilage grafts, seven cartilage-molding sutures and a prolene mesh graft for alar base support. Post-operative evaluation of nasal symmetry was undertaken using the validated computer program ‘SymNose’. Functional outcome and patient satisfaction were assessed using the NOSE scale and ROE (rhinoplasty outcome evaluation) questionnaires. The single group study design used the non-parametric matching pairs Wilcoxon Sign test (p < 0.001), and showed overall good to excellent functional and aesthetic outcomes, including nasal projection and tip definition, and higher scores of the digital SymNose grading system. Objective assessment of the Gujrat cleft rhinoplasty technique demonstrates its aesthetic appeal and functional versatility. Overall it is a simple and reproducible technique, with no significant complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cleft%20lip%20and%20palate" title="cleft lip and palate">cleft lip and palate</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20rhinoplasty" title=" congenital rhinoplasty"> congenital rhinoplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=nasal%20deformity" title=" nasal deformity"> nasal deformity</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20rhinoplasty" title=" secondary rhinoplasty"> secondary rhinoplasty</a> </p> <a href="https://publications.waset.org/abstracts/77168/a-single-stage-cleft-rhinoplasty-technique-for-primary-unilateral-cleft-lip-and-palate-the-gujrat-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77168.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">203</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">509</span> Minimal Incision Cochlear Implantation in Congenital Abnormality: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munish%20Saroch">Munish Saroch</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Saini"> Amit Saini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Many children with congenital malformation of inner ear have undergone cochlear implant (CI) surgery. The results for cochlear implant surgery in these children are very encouraging and provide a ray of hope for these patients. Objective: The main objective of this presentation is to prove that even in Mondini’s deformity Minimal incision cochlear implantation improves cosmesis, reduces post-operative infection and earliest switch on of device. Methods: We report a case of two-year-old child suffering from Mondini’s deformity who underwent CI with minimal incision cochlear implantation (MICI). MICI has been developed with the aims of reducing the impact of surgery on the patient without any preoperative shaving of hairs. Results: Patient after surgery with MICI showed better looking postauricular scar, low post-operative morbidity in comparison to conventional wider access approach and hence earliest switch on of device (1st post operative day). Conclusion: We are of opinion that MICI is safe and successful in Mondini’s deformity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CI" title="CI">CI</a>, <a href="https://publications.waset.org/abstracts/search?q=Cochlear%20Implant" title=" Cochlear Implant"> Cochlear Implant</a>, <a href="https://publications.waset.org/abstracts/search?q=MICI" title=" MICI"> MICI</a>, <a href="https://publications.waset.org/abstracts/search?q=Minimal%20Incision%20Cochlear%20Implantation" title=" Minimal Incision Cochlear Implantation"> Minimal Incision Cochlear Implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=HL" title=" HL"> HL</a>, <a href="https://publications.waset.org/abstracts/search?q=Hearing%20Loss" title=" Hearing Loss"> Hearing Loss</a>, <a href="https://publications.waset.org/abstracts/search?q=HRCT" title=" HRCT"> HRCT</a>, <a href="https://publications.waset.org/abstracts/search?q=High%20Resolution%20Computer%20Tomography" title=" High Resolution Computer Tomography"> High Resolution Computer Tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI" title=" MRI"> MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=Magnetic%20resonance%20imaging" title=" Magnetic resonance imaging"> Magnetic resonance imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=SCI" title=" SCI"> SCI</a>, <a href="https://publications.waset.org/abstracts/search?q=Standard%20cochlear%20implantation" title=" Standard cochlear implantation"> Standard cochlear implantation</a> </p> <a href="https://publications.waset.org/abstracts/46030/minimal-incision-cochlear-implantation-in-congenital-abnormality-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46030.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">216</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">508</span> “To Err Is Human…” Revisiting Oral Error Correction in Class</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Steven%20Rosenstein">David Steven Rosenstein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The widely accepted “Input Theory” of language acquisition proposes that language is basically acquired unconsciously through extensive exposure to all kinds of natural oral and written sources, especially those where the level of the input is slightly above the learner’s competence. As such, it implies that oral error correction by teachers in a classroom is unnecessary, a waste of time, and maybe even counterproductive. And yet, oral error correction by teachers in the classroom continues to be a very common phenomenon. While input theory advocates claim that such correction doesn’t work, interrupts a student’s train of thought, harms fluency, and may cause students embarrassment and fear, many teachers would disagree. They would claim that students know they make mistakes and want to be corrected in order to know they are improving, thereby encouraging students’ desire to keep studying. Moreover, good teachers can create a positive atmosphere where students will not be embarrassed or fearful. Perhaps now is the time to revisit oral error correction in the classroom and consider the results of research carried out long ago by the present speaker. The research indicates that oral error correction may be beneficial in many cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=input%20theory" title="input theory">input theory</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20acquisition" title=" language acquisition"> language acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%27%20corrections" title=" teachers' corrections"> teachers' corrections</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20errors" title=" recurrent errors"> recurrent errors</a> </p> <a href="https://publications.waset.org/abstracts/188530/to-err-is-human-revisiting-oral-error-correction-in-class" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188530.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">32</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">507</span> Tibial Hemimelia Type VIIa: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Medrano">M.

Due to pre-existing case studies and literature, there is now a better understanding of the genetics, etiology and pathoanatomy of tibial hemimelia, but an underlying cause is generally unknown. This presentation aims to discuss a rare, congenital lower limb deficiency observed in a patient in order to identify potential prenatal risk factors and future considerations for the patient’s well-being. Observation: A newborn female child, born full term via spontaneous vaginal delivery after induction of labor to unaffected and non-consanguineous parents. The prenatal course was notable for limited and disjointed prenatal care as well as maternal tobacco and marijuana use, anemia of pregnancy, and inadequate weight gain. Prenatal imaging showed lower extremity deformity with the inability to visualize tibia and bilateral clubfeet in the setting of Intrauterine Growth Restriction (IUGR). The patient presented with right equino varus deformity of the foot and right knee joint deformity. Radiological imaging showed the absence of the right tibia and varus angulation of the right foot with dislocation of the tibiotalar joint. Normal femur with lateral and mild anterior displacement of a wide fibula (Weber Type VIIa). Due to the absence of the patient’s tibia and knee extensor mechanism, the patient was not a candidate for reconstructive surgery and ultimately underwent successful right knee disarticulation. Discussion and Conclusion: By utilizing a retrospective chart review of this case, possible risk factors in prenatal care may be identified and add to existing knowledge on etiology. Hopefully, a cause can be clearly identified in the future and, thus, addressed in the prenatal period. In addition, we can investigate the patient’s well-being and adjustment post-operatively to support outpatient management of an uncommon anomaly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tibial%20hemimelia" title="Tibial hemimelia">Tibial hemimelia</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20care" title=" prenatal care"> prenatal care</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20orthopedics" title=" pediatric orthopedics"> pediatric orthopedics</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20deformity" title=" congenital deformity"> congenital deformity</a> </p> <a href="https://publications.waset.org/abstracts/142499/tibial-hemimelia-type-viia-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142499.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">159</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">506</span> Combined Tarsal Coalition Resection and Arthroereisis in Treatment of Symptomatic Rigid Flat Foot in Pediatric Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Zaidman">Michael Zaidman</a>, <a href="https://publications.waset.org/abstracts/search?q=Naum%20Simanovsky"> Naum Simanovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction. Symptomatic tarsal coalition with rigid flat foot often demands operative solution. An isolated coalition resection does not guarantee pain relief; correction of co-existing foot deformity may be required. The objective of the study was to analyze the results of combination of tarsal coalition resection and arthroereisis. Patients and methods. We retrospectively reviewed medical records and radiographs of children operatively treated in our institution for symptomatic calcaneonavicular or talocalcaneal coalition between the years 2019 and 2022. Eight patients (twelve feet), 4 boys and 4 girls with mean age 11.2 years, were included in the study. In six patients (10 feet) calcaneonavicular coalition was diagnosed, two patients (two feet) sustained talonavicular coalition. To quantify degrees of foot deformity, we used calcaneal pitch angle, lateral talar-first metatarsal (Meary's) angle, and talonavicular coverage angle. The clinical results were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Score. Results. The mean follow-up was 28 month. The preoperative mean talonavicular coverage angle was 17,75º as compared with postoperative mean angle of 5.4º. The calcaneal pitch angle improved from mean 6,8º to 16,4º. The mean preoperative Meary’s angle of -11.3º improved to mean 2.8º. The preoperative mean AOFAS score improved from 54.7 to 93.1 points post-operatively. In nine of twelve feet, overall clinical outcome judged by AOFAS scale was excellent (90-100 points), in three feet was good (80-90 points). Six patients (ten feet) obviously improved their subtalar range of motion. Conclusion. For symptomatic stiff or rigid flat feet associated with tarsal coalition, the combination of coalition resection and arthroereisis leads to normalization of radiographic parameters, clinical and functional improvement with good patient’s satisfaction and likely to be more effective than the isolated procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rigid%20flat%20foot" title="rigid flat foot">rigid flat foot</a>, <a href="https://publications.waset.org/abstracts/search?q=tarsal%20coalition%20resection" title=" tarsal coalition resection"> tarsal coalition resection</a>, <a href="https://publications.waset.org/abstracts/search?q=arthroereisis" title=" arthroereisis"> arthroereisis</a>, <a href="https://publications.waset.org/abstracts/search?q=outcome" title=" outcome"> outcome</a> </p> <a href="https://publications.waset.org/abstracts/174910/combined-tarsal-coalition-resection-and-arthroereisis-in-treatment-of-symptomatic-rigid-flat-foot-in-pediatric-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174910.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">64</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">505</span> Operative Technique of Glenoid Anteversion Osteotomy and Soft Tissue Rebalancing for Brachial Plexus Birth Palsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Zaidman">Michael Zaidman</a>, <a href="https://publications.waset.org/abstracts/search?q=Naum%20Simanovsky"> Naum Simanovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most of brachial birth palsies are transient.

For this, it is not always put into leading technological advances to improve the performance of tomographic gamma camera in terms of detection, collimation, reconstruction and correction of tomographic images methods. We have to master firstly the choice of various acquisition and reconstruction parameters, accessible to clinical cases and using the attenuation and scatter correction methods to always optimize quality image and minimized to the maximum dose received by the patient. In this work, an evaluation of qualitative and quantitative tomographic images is performed based on the acquisition parameters (counts per projection) and reconstruction parameters (filter type, associated cutoff frequency). In addition, methods for correcting physical effects such as attenuation and scatter degrading the image quality and preventing precise quantitative of the reconstructed slices are also presented. Two approaches of attenuation and scatter correction are implemented: the attenuation correction by CHANG method with a filtered back projection reconstruction algorithm and scatter correction by the subtraction JASZCZAK method. Our results are considered as such recommandation, which permits to determine the origin of the different artifacts observed both in quality control tests and in clinical images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attenuation" title="attenuation">attenuation</a>, <a href="https://publications.waset.org/abstracts/search?q=scatter" title=" scatter"> scatter</a>, <a href="https://publications.waset.org/abstracts/search?q=reconstruction%20filter" title=" reconstruction filter"> reconstruction filter</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20quality" title=" image quality"> image quality</a>, <a href="https://publications.waset.org/abstracts/search?q=acquisition%20and%20reconstruction%20parameters" title=" acquisition and reconstruction parameters"> acquisition and reconstruction parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=SPECT" title=" SPECT"> SPECT</a> </p> <a href="https://publications.waset.org/abstracts/38755/the-effect-of-the-acquisition-and-reconstruction-parameters-in-quality-of-spect-tomographic-images-with-attenuation-and-scatter-correction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38755.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">453</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">502</span> Correction Factor to Enhance the Non-Standard Hammer Effect Used in Standard Penetration Test </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20R.%20Khater">Khaled R. Khater</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The weight of the SPT hammer is standard (0.623kN). The locally manufacturer drilling rigs use hammers, sometimes deviating off the standard weight. This affects the field measured blow counts (Nf) consequentially, affecting most of correlations previously obtained, as they were obtained based on standard hammer weight. The literature presents energy corrections factor (η2) to be applied to the SPT total input energy. This research investigates the effect of the hammer weight variation, as a single parameter, on the field measured blow counts (Nf). The outcome is a correction factor (ηk), equation, and correction chart. They are recommended to adjust back the measured misleading (Nf) to the standard one as if the standard hammer is used. This correction is very important to be done in such cases where a non-standard hammer is being used because the bore logs in any geotechnical report should contain true and representative values (Nf), let alone the long records of correlations, already in hand. The study here-in is achieved by using laboratory physical model to simulate the SPT dripping hammer mechanism. It is designed to allow different hammer weights to be used. Also, it is manufactured to avoid and eliminate the energy loss sources. This produces a transmitted efficiency up to 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correction%20factors" title="correction factors">correction factors</a>, <a href="https://publications.waset.org/abstracts/search?q=hammer%20weight" title=" hammer weight"> hammer weight</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20model" title=" physical model"> physical model</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20penetration%20test" title=" standard penetration test"> standard penetration test</a> </p> <a href="https://publications.waset.org/abstracts/36848/correction-factor-to-enhance-the-non-standard-hammer-effect-used-in-standard-penetration-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36848.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">387</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">501</span> A Survey of 2nd Year Students' Frequent Writing Error and the Effects of Participatory Error Correction Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaiwat%20Tantarangsee">Chaiwat Tantarangsee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purposes of this study are 1) to study the effects of participatory error correction process and 2) to find out the students’ satisfaction of such error correction process. This study is a Quasi Experimental Research with single group, in which data is collected 5 times preceding and following 4 experimental studies of participatory error correction process including providing coded indirect corrective feedback in the students’ texts with error treatment activities. Samples include 28 2nd year English Major students, Faculty of Humanities and Social Sciences, Suan Sunandha Rajabhat University. Tool for experimental study includes the lesson plan of the course; Reading and Writing English for Academic Purposes II, and tools for data collection include 5 writing tests of short texts and a questionnaire. Based on formative evaluation of the students’ writing ability prior to and after each of the 4 experiments, the research findings disclose the students’ higher scores with statistical difference at 0.05. Moreover, in terms of the effect size of such process, it is found that for mean of the students’ scores prior to and after the 4 experiments; d equals 1.0046, 1.1374, 1.297, and 1.0065 respectively. It can be concluded that participatory error correction process enables all of the students to learn equally well and there is improvement in their ability to write short texts. Finally, the students’ overall satisfaction of the participatory error correction process is in high level (Mean=4.32, S.D.=0.92). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coded%20indirect%20corrective%20feedback" title="coded indirect corrective feedback">coded indirect corrective feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20error%20correction%20process" title=" participatory error correction process"> participatory error correction process</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20treatment" title=" error treatment"> error treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=humanities%20and%20social%20sciences" title=" humanities and social sciences"> humanities and social sciences</a> </p> <a href="https://publications.waset.org/abstracts/19731/a-survey-of-2nd-year-students-frequent-writing-error-and-the-effects-of-participatory-error-correction-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19731.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">523</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">500</span> A Novel Way to Create Qudit Quantum Error Correction Codes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arun%20Moorthy">Arun Moorthy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quantum computing promises to provide algorithmic speedups for a number of tasks; however, similar to classical computing, effective error-correcting codes are needed. Current quantum computers require costly equipment to control each particle, so having fewer particles to control is ideal. Although traditional quantum computers are built using qubits (2-level systems), qudits (more than 2-levels) are appealing since they can have an equivalent computational space using fewer particles, meaning fewer particles need to be controlled. Currently, qudit quantum error-correction codes are available for different level qudit systems; however, these codes have sometimes overly specific constraints. When building a qudit system, it is important for researchers to have access to many codes to satisfy their requirements. This project addresses two methods to increase the number of quantum error correcting codes available to researchers. The first method is generating new codes for a given set of parameters. The second method is generating new error-correction codes by using existing codes as a starting point to generate codes for another level (i.e., a 5-level system code on a 2-level system). So, this project builds a website that researchers can use to generate new error-correction codes or codes based on existing codes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=qudit" title="qudit">qudit</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction" title=" error correction"> error correction</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum" title=" quantum"> quantum</a>, <a href="https://publications.waset.org/abstracts/search?q=qubit" title=" qubit"> qubit</a> </p> <a href="https://publications.waset.org/abstracts/138747/a-novel-way-to-create-qudit-quantum-error-correction-codes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138747.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">160</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">499</span> An Efficient Algorithm of Time Step Control for Error Correction Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youngji%20Lee">Youngji Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonghyeon%20Jeon"> Yonghyeon Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunyoung%20Bu"> Sunyoung Bu</a>, <a href="https://publications.waset.org/abstracts/search?q=Philsu%20Kim"> Philsu Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to construct an algorithm of time step control for the error correction method most recently developed by one of the authors for solving stiff initial value problems. It is achieved with the generalized Chebyshev polynomial and the corresponding error correction method. The main idea of the proposed scheme is in the usage of the duplicated node points in the generalized Chebyshev polynomials of two different degrees by adding necessary sample points instead of re-sampling all points. At each integration step, the proposed method is comprised of two equations for the solution and the error, respectively. The constructed algorithm controls both the error and the time step size simultaneously and possesses a good performance in the computational cost compared to the original method. Two stiff problems are numerically solved to assess the effectiveness of the proposed scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stiff%20initial%20value%20problem" title="stiff initial value problem">stiff initial value problem</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction%20method" title=" error correction method"> error correction method</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20Chebyshev%20polynomial" title=" generalized Chebyshev polynomial"> generalized Chebyshev polynomial</a>, <a href="https://publications.waset.org/abstracts/search?q=node%20points" title=" node points "> node points </a> </p> <a href="https://publications.waset.org/abstracts/16920/an-efficient-algorithm-of-time-step-control-for-error-correction-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16920.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">573</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">498</span> Error Correction Method for 2D Ultra-Wideband Indoor Wireless Positioning System Using Logarithmic Error Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phornpat%20Chewasoonthorn">Phornpat Chewasoonthorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Surat%20Kwanmuang"> Surat Kwanmuang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indoor positioning technologies have been evolved rapidly. They augment the Global Positioning System (GPS) which requires line-of-sight to the sky to track the location of people or objects. This study developed an error correction method for an indoor real-time location system (RTLS) based on an ultra-wideband (UWB) sensor from Decawave. Multiple stationary nodes (anchor) were installed throughout the workspace. The distance between stationary and moving nodes (tag) can be measured using a two-way-ranging (TWR) scheme. The result has shown that the uncorrected ranging error from the sensor system can be as large as 1 m. To reduce ranging error and thus increase positioning accuracy, This study purposes an online correction algorithm using the Kalman filter. The results from experiments have shown that the system can reduce ranging error down to 5 cm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indoor%20positioning" title="indoor positioning">indoor positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-wideband" title=" ultra-wideband"> ultra-wideband</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction" title=" error correction"> error correction</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a> </p> <a href="https://publications.waset.org/abstracts/138120/error-correction-method-for-2d-ultra-wideband-indoor-wireless-positioning-system-using-logarithmic-error-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138120.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">160</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">497</span> Study of Side Effects of Myopia Contact Correction by Soft Lenses and Orthokeratology Lenses among Medical Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Iu.%20Hrizhymalska">K.

To study and copare the side effects of myopia contact correction by soft lenses and orthokeratology lenses among medical students. Patients and methods: 34 students (68 eyes) with moderate and severe myopia, who used contact correction of myopia for 2-4 years, were examined. Some of them used soft lenses, while others - orthokeratology lenses. Methods were used: biomicroscopy of the eye surface, Schirmer's test, Norn's test, survey regarding satisfaction with use. Results. Corneal vascularization along the limbus was noted in 4 (5%) eyes of the examined students. In 8 (11%) eyes, symptoms of mild dry eye disease were detected. 2 (3%) eyes showed signs of meibomitis. Allergic conjunctivitis was observed in 4 (5%) eyes, and a purulent corneal ulcer was present in 1 eye. Surveys have shown that orthokeratology lenses unlike soft lenses don't limit everyday activity (in sports, tourism, swimming etc.), they also don't cause discomfort during temperature changes and reduce existing symptoms of dry eye disease. Conclusion. Thus, myopia contact correction is one of the optimal options among students, which allows to expand physical and mental activity. However, taking into account the frequency of side effects in users of soft contact lenses, it is necessary to carry out prevention and treatment of myopia in medical students, follow the recommendations for use, instill preservative-free tear substitutes with trehalose when symptoms of dry eye appear. Also when side reactions occur, contact correction with soft lenses should be changed to orthokeratology lenses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correction" title="correction">correction</a>, <a href="https://publications.waset.org/abstracts/search?q=myopia" title=" myopia"> myopia</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20lenses" title=" soft lenses"> soft lenses</a>, <a href="https://publications.waset.org/abstracts/search?q=orthokeratology" title=" orthokeratology"> orthokeratology</a>, <a href="https://publications.waset.org/abstracts/search?q=specracles" title=" specracles"> specracles</a>, <a href="https://publications.waset.org/abstracts/search?q=cornea" title=" cornea"> cornea</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20eye" title=" dry eye"> dry eye</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20effects" title=" side effects"> side effects</a>, <a href="https://publications.waset.org/abstracts/search?q=refractive%20errors" title=" refractive errors"> refractive errors</a> </p> <a href="https://publications.waset.org/abstracts/182748/study-of-side-effects-of-myopia-contact-correction-by-soft-lenses-and-orthokeratology-lenses-among-medical-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182748.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">54</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">496</span> Environmental Fatigue Analysis for Control Rod Drive Mechanisms Seal House</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuejiao%20Shao">Xuejiao Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianguo%20Chen"> Jianguo Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaolong%20Fu"> Xiaolong Fu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the elastoplastic strain correction factor computed by software of ANSYS was modified, and the fatigue usage factor in air was also corrected considering in water under reactor operating condition. The fatigue of key parts on control rod drive mechanisms was analyzed considering the influence of environmental fatigue caused by the coolant in the react pressure vessel. The elastoplastic strain correction factor was modified by analyzing thermal and mechanical loads separately referring the rules of RCC-M 2002. The new elastoplastic strain correction factor Ke(mix) is computed to replace the original Ke computed by the software of ANSYS when evaluating the fatigue produced by thermal and mechanical loads together. Based on the Ke(mix) and the usage cycle and fatigue design curves, the new range of primary plus secondary stresses was evaluated to obtain the final fatigue usage factor. The results show that the precision of fatigue usage factor can be elevated by using modified Ke when the amplify of the primary and secondary stress is large to some extent. One approach has been proposed for incorporating the environmental effects considering the effects of reactor coolant environments on fatigue life in terms of an environmental correction factor Fen, which is the ratio of fatigue life in air at room. To incorporate environmental effects into the RCCM Code fatigue evaluations, the fatigue usage factor based on the current Code design curves is multiplied by the correction factor. The contribution of environmental effects to results is discussed. Fatigue life decreases logarithmically with decreasing strain rate below 10%/s, which is insensitive to strain rate when temperatures below 100°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20fatigue" title="environmental fatigue">environmental fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=usage%20factor" title=" usage factor"> usage factor</a>, <a href="https://publications.waset.org/abstracts/search?q=elastoplastic%20strain%20correction%20factor" title=" elastoplastic strain correction factor"> elastoplastic strain correction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20correction" title=" environmental correction"> environmental correction</a> </p> <a href="https://publications.waset.org/abstracts/59209/environmental-fatigue-analysis-for-control-rod-drive-mechanisms-seal-house" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59209.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">324</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">495</span> Salter Pelvic Osteotomy for the Treatment of Developmental Dysplasia of the Hip: Assessment of Postoperative Results and Risk Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suvorov%20Vasyl">Suvorov Vasyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipchuk%20Viktor"> Filipchuk Viktor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: If non-surgical treatment of developmental dysplasia of the hip (DDH) fails or if DDH is late-detected, surgery is necessary. Salter pelvic osteotomy (SPO) is an effective surgical option for such cases. The objectives of this study were to assess the results after SPO, evaluate risk factors, and reveal those radiological parameters that may correlate with the results. Mid- and long-term postoperative results after SPO in 17 patients (22 hip joints) were analyzed. Risk factors included those that do not depend on the surgeon (patient's age, value of the acetabular index (AI) preoperatively, DDH Tonnis grade) and those that depend on the surgeon (amount of AI correction). To radiological parameters which may correlate with the amount of AI correction, we referred distance "d" and the lateral rotation angle. Results: SPO allows performing AI correction in ranges 24.1 ± 6.5°. Excellent and good clinical results were obtained in 95.5% of patients; excellent and good radiological results in 86.4% of patients. Risk factors that do not depend on the surgeon were older patient’s age and higher preoperative AI values (p < 0.05). The risk factor that depends on the surgeon was the amount of AI correction (p < 0.05). The distance "d" was recognized as a radiological parameter that may indicate sufficient AI correction (p < 0.05). Conclusion: In older patients with a higher preoperative AI value, the results will be predictably worse. The surgeon may influence the result with a greater amount of AI correction (which may also be indicated radiologically by the distance "d" values). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developmental%20dysplasia%20of%20the%20hip" title="developmental dysplasia of the hip">developmental dysplasia of the hip</a>, <a href="https://publications.waset.org/abstracts/search?q=results" title=" results"> results</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a>, <a href="https://publications.waset.org/abstracts/search?q=pelvic%20osteotomy" title=" pelvic osteotomy"> pelvic osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=salter%20osteotomy" title=" salter osteotomy"> salter osteotomy</a> </p> <a href="https://publications.waset.org/abstracts/147537/salter-pelvic-osteotomy-for-the-treatment-of-developmental-dysplasia-of-the-hip-assessment-of-postoperative-results-and-risk-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147537.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">131</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">494</span> A Sliding Mesh Technique and Compressibility Correction Effects of Two-Equation Turbulence Models for a Pintle-Perturbed Flow Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Y.%20Heo">J.

Sekine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aerial photogrammetry of shallow water bottoms has the potential to be an efficient high-resolution survey technique for shallow water topography, thanks to the advent of convenient UAV and automatic image processing techniques Structure-from-Motion (SfM) and Multi-View Stereo (MVS)). However, it suffers from the systematic overestimation of the bottom elevation, due to the light refraction at the air-water interface. In this study, we present an empirical method to correct for the effect of refraction after the usual SfM-MVS processing, using common software. The presented method utilizes the empirical relation between the measured true depth and the estimated apparent depth to generate an empirical correction factor. Furthermore, this correction factor was utilized to convert the apparent water depth into a refraction-corrected (real-scale) water depth. To examine its effectiveness, we applied the method to two river sites, and compared the RMS errors in the corrected bottom elevations with those obtained by three existing methods. The result shows that the presented method is more effective than the two existing methods: The method without applying correction factor and the method utilizes the refractive index of water (1.34) as correction factor. In comparison with the remaining existing method, which used the additive terms (offset) after calculating correction factor, the presented method performs well in Site 2 and worse in Site 1. However, we found this linear regression method to be unstable when the training data used for calibration are limited. It also suffers from a large negative bias in the correction factor when the apparent water depth estimated is affected by noise, according to our numerical experiment. Overall, the good accuracy of refraction correction method depends on various factors such as the locations, image acquisition, and GPS measurement conditions. The most effective method can be selected by using statistical selection (e.g. leave-one-out cross validation). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bottom%20elevation" title="bottom elevation">bottom elevation</a>, <a href="https://publications.waset.org/abstracts/search?q=MVS" title=" MVS"> MVS</a>, <a href="https://publications.waset.org/abstracts/search?q=river" title=" river"> river</a>, <a href="https://publications.waset.org/abstracts/search?q=SfM" title=" SfM"> SfM</a> </p> <a href="https://publications.waset.org/abstracts/63370/a-simple-and-empirical-refraction-correction-method-for-uav-based-shallow-water-photogrammetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63370.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">492</span> Study on Hybridization between Clarias gariepinus (Burchell 1822) and Heterobranchus bidorsalis (Geoffroy Saint Hilaire, 1809)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wasiu%20Olaniyi">Wasiu Olaniyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ofelia%20Omitogun"> Ofelia Omitogun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hybridization has been of importance in both research and commercial aquaculture due to its benefits such as increased growth rate, sex ratio manipulation, production of sterile species and many other desirable economic traits. In this study, we successfully produced hybrids between crosses of Clariid catfish species of Clarias gariepinus and Heterobranchus bidorsalis for stock improvement. Milt and eggs from parent broodstock of C. gariepinus and H. bidorsalis were collected for both intrageneric and interspecific hybridization, viz: same parent species crosses (♀C. gariepinus ×♂C. gariepinus; ♀H. bidorsalis × ♂H. bidorsalis) and inter-specific crosses (♀H. bidorsalis × ♂C. gariepinus; ♀C. gariepinus × ♂H. bidorsalis). These crosses were made in triplicates whereby the data on latency period, fertility, hatchability, deformity, and survival were recorded. A phenotypic form of distinction was registered in the hybrid ♀C. gariepinus × ♂H. bidorsalis that was smooth-greyed while its reciprocal cross was marpatic. The parent species C. gariepinus had greyed-marpatic color while the H. bidorsalis was yellowish-brown. Fertility data revealed the significant difference (p < 0.05) between the hybrid cross ♀C. gariepinus × ♂H. bidorsalis (88.00 ± 1.00%) compared to its reciprocal ♀H. bidorsalis × ♂C. gariepinus (71.67 ± 10.41%) which further had carried over effects to hatchability. The reciprocal ♀H. bidorsalis × ♂C. gariepinus recorded the highest deformity (11.67 ± 3.06%) that was significantly different (p < 0.05) from the rest of the crosses. Also, an outcome of equal sex ratio in the hybrids compared with the two parent species was shown. Specific growth rate (SGR) data revealed highest significant difference (p < 0.05) in the hybrid ♀C. gariepinus × ♂H. bidorsalis (2.64 ± 0.09%), followed by the cross of ♀C. gariepinus × ♂ C. gariepinus (1.91 ± 0.02%) while there were no significant differences (p > 0.05) between the reciprocal hybrid ♀H. bidorsalis × ♂C. gariepinus (2.20 ± 0.57%) and ♀H. bidorsalis × ♂H. bidorsalis (2.19 ± 0.19%). The SGR analysis proved that the crosses ♀C. gariepinus × ♂C. gariepinus had slow growth performance compared to its hybrid ♀C. gariepinus × ♂H. bidorsalis. Critical evaluation based on survival and specific growth performance showed the superiority of the hybrid ♀C. gariepinus × ♂H. bidorsalis. The least survival in reciprocal hybrid ♀H. bidorsalis × ♂C. gariepinus (27.33%) can be explained by significant deformity (11.67%) recorded due to maternal effects.

The implemented algorithm computes uniform forces normal to the grinding surface of the workpiece, by constructing a curvature path in the spatial coordinates using the spline method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABB%20industrial%20robot" title="ABB industrial robot">ABB industrial robot</a>, <a href="https://publications.waset.org/abstracts/search?q=grinding%20process" title=" grinding process"> grinding process</a>, <a href="https://publications.waset.org/abstracts/search?q=offline%20programming" title=" offline programming"> offline programming</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20data%20extraction" title=" CAD data extraction"> CAD data extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20correction%20algorithm" title=" force correction algorithm"> force correction algorithm</a> </p> <a href="https://publications.waset.org/abstracts/49221/development-and-implementation-of-curvature-dependent-force-correction-algorithm-for-the-planning-of-forced-controlled-robotic-grinding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49221.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">362</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">490</span> Bridgeless Boost Power Factor Correction Rectifier with Hold-Up Time Extension Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Chiang%20Hua">Chih-Chiang Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Hsiung%20Fang"> Yi-Hsiung Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Jhen%20Siao"> Yuan-Jhen Siao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A bridgeless boost (BLB) power factor correction (PFC) rectifier with hold-up time extension circuit is proposed in this paper. A full bridge rectifier is widely used in the front end of the ac/dc converter. Since the shortcomings of the full bridge rectifier, the bridgeless rectifier is developed. A BLB rectifier topology is utilized with the hold-up time extension circuit. Unlike the traditional hold-up time extension circuit, the proposed extension scheme uses fewer active switches to achieve a longer hold-up time.

The changing climate has been attributed to rising concentrations of greenhouse gases, including environmental changes such as ecosystems and land-uses. Climatic projections have been carried out under the auspices of the intergovernmental panel on climate change where a couple of models have been run to inform us about the likelihood of future climates. Since one of the major forcings informing the changing climate is emission of greenhouse gases, different scenarios have been proposed and future climates for different periods presented. The global climate models project different areas to experience different impacts. While regional modeling is being carried out for high impact studies, bias correction is less documented. Yet, the regional climate models suffer bias which introduces uncertainty. This is addressed in this study by bias correcting the regional models. This study uses the Weather Research and Forecasting model under different representative concentration pathways and correcting the products of these models using observed climatic data. This study notes that bias correction (e.g., the running-mean bias correction; the best easy systematic estimator method; the simple linear regression method, nearest neighborhood, weighted mean) improves the climatic projection skill and therefore reduce the uncertainty inherent in the climatic projections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bias%20correction" title="bias correction">bias correction</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20projections" title=" climatic projections"> climatic projections</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20models" title=" numerical models"> numerical models</a>, <a href="https://publications.waset.org/abstracts/search?q=representative%20concentration%20pathways" title=" representative concentration pathways"> representative concentration pathways</a> </p> <a href="https://publications.waset.org/abstracts/111018/reducing-uncertainty-in-climate-projections-over-uganda-by-numerical-models-using-bias-correction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111018.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">119</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">488</span> Vertebral Transverse Open Wedge Osteotomy in Correction of Thoracolumbar Kyphosis Resulting from Ankylosing Spondylitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20AliReza%20Mirghasemi">S.

Several operative techniques have been used in this stage, but little knowledge exists on the indications for and outcome of these methods. In this study, we examined the efficacy of monosegmental transverse open wedge osteotomy of L3 in 11 patients with progressive spinal kyphosis. The average correction was 36̊ (20 to 42) with no loss of correction after operation. The average operating time was 120 minutes (100 to 130) and the mean blood loss was 1500 ml (1100 to 2000). Osteotomy corrected all patients sufficiently to allow them to see ahead and their posture was improved. There were no fatal complications but one patient had paraplegia after the operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankylosing%20spondylitis" title="ankylosing spondylitis">ankylosing spondylitis</a>, <a href="https://publications.waset.org/abstracts/search?q=thoracolumbar%20kyphosis" title=" thoracolumbar kyphosis"> thoracolumbar kyphosis</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20wedge%20osteotomy" title=" open wedge osteotomy"> open wedge osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=L3%20transverse%20open%20wedge%20osteotomy" title=" L3 transverse open wedge osteotomy"> L3 transverse open wedge osteotomy</a> </p> <a href="https://publications.waset.org/abstracts/34782/vertebral-transverse-open-wedge-osteotomy-in-correction-of-thoracolumbar-kyphosis-resulting-from-ankylosing-spondylitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34782.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">393</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">487</span> Application of Residual Correction Method on Hyperbolic Thermoelastic Response of Hollow Spherical Medium in Rapid Transient Heat Conduction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Po-Jen%20Su">Po-Jen Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Huann-Ming%20Chou"> Huann-Ming Chou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article we uses the residual correction method to deal with transient thermoelastic problems with a hollow spherical region when the continuum medium possesses spherically isotropic thermoelastic properties. Based on linear thermoelastic theory, the equations of hyperbolic heat conduction and thermoelastic motion were combined to establish the thermoelastic dynamic model with consideration of the deformation acceleration effect and non-Fourier effect under the condition of transient thermal shock. The approximate solutions of temperature and displacement distributions are obtained using the residual correction method based on the maximum principle in combination with the finite difference method, making it easier and faster to obtain upper and lower approximations of exact solutions. The proposed method is found to be an effective numerical method with satisfactory accuracy. Moreover, the result shows that the effect of transient thermal shock induced by deformation acceleration is enhanced by non-Fourier heat conduction with increased peak stress. The influence on the stress increases with the thermal relaxation time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maximum%20principle"
