This work explores imputations in an attempt to improve accuracy. This work implements Linear Regression, Lasso, Linear Support Vector Regression, Bayesian Ridge, K Nearest Neighbors (KNN), and Random Forest machine learning techniques to impute audiogram frequencies ranging from 125Hz to 8000Hz. The data contains patients who had or were candidates for cochlear implants. Accuracy is compared across two different Nested Cross-Validation k values. Over 4000 audiograms were used from 800 unique patients. Additionally, training on data combines and compares left and right ear audiograms versus single ear side audiograms. The accuracy achieved using Root Mean Square Error (RMSE) values for the best models for Random Forest ranges from 4.74 to 6.37. The R\textsuperscript{2} values for the best models for Random Forest ranges from .91 to .96. The accuracy achieved using RMSE values for the best models for KNN ranges from 5.00 to 7.72. The R\textsuperscript{2} values for the best models for KNN ranges from .89 to .95. The best imputation models received R\textsuperscript{2} between .89 to .96 and RMSE values less than 8dB. We also show that the accuracy of classification predictive models performed better with our best imputation models versus constant imputations by a two percent increase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=audiograms" title=" audiograms"> audiograms</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20imputations" title=" data imputations"> data imputations</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20imputations" title=" single imputations"> single imputations</a> </p> <a href="https://publications.waset.org/abstracts/171211/single-imputation-for-audiograms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171211.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">82</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">4743</span> Primary Analysis of a Randomized Controlled Trial of Topical Analgesia Post Haemorrhoidectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20Jin">James Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Weisi%20Xia"> Weisi Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Runzhe%20Gao"> Runzhe Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain%20Vandal"> Alain Vandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Darren%20Svirkis"> Darren Svirkis</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Hill"> Andrew Hill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Post-haemorrhoidectomy pain is concerned by patients/clinicians. Minimizing the postoperation pain is highly interested clinically. Combinations of topical cream targeting three hypothesised post-haemorrhoidectomy pain mechanisms were developed and their effectiveness were evaluated. Specifically, a multi-centred double-blinded randomized clinical trial (RCT) was conducted in adults undergoing excisional haemorrhoidectomy. The primary analysis was conveyed on the data collected to evaluate the effectiveness of the combinations of topical cream targeting three hypothesized pain mechanisms after the operations. Methods: 192 patients were randomly allocated to 4 arms (each arm has 48 patients), and each arm was provided with pain cream 10% metronidazole (M), M and 2% diltiazem (MD), M with 4% lidocaine (ML), or MDL, respectively. Patients were instructed to apply topical treatments three times a day for 7 days, and record outcomes for 14 days after the operations. The primary outcome was VAS pain on day 4. Covariates and models were selected in the blind review stage. Multiple imputations were applied for the missingness. LMER, GLMER models together with natural splines were applied. Sandwich estimators and Wald statistics were used. P-values < 0.05 were considered as significant. Conclusions: The addition of topical lidocaine or diltiazem to metronidazole does not add any benefit. ML had significantly better pain and recovery scores than combination MDL. Multimodal topical analgesia with ML after haemorrhoidectomy could be considered for further evaluation. Further trials considering only 3 arms (M, ML, MD) might be worth exploring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RCT" title="RCT">RCT</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20analysis" title=" primary analysis"> primary analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20imputation" title=" multiple imputation"> multiple imputation</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20scores" title=" pain scores"> pain scores</a>, <a href="https://publications.waset.org/abstracts/search?q=haemorrhoidectomy" title=" haemorrhoidectomy"> haemorrhoidectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=analgesia" title=" analgesia"> analgesia</a>, <a href="https://publications.waset.org/abstracts/search?q=lmer" title=" lmer"> lmer</a> </p> <a href="https://publications.waset.org/abstracts/162939/primary-analysis-of-a-randomized-controlled-trial-of-topical-analgesia-post-haemorrhoidectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162939.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">120</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">4742</span> Improved Accuracy of Ratio Multiple Valuation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julianto%20Agung%20Saputro">Julianto Agung Saputro</a>, <a href="https://publications.waset.org/abstracts/search?q=Jogiyanto%20Hartono"> Jogiyanto Hartono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple valuation is widely used by investors and practitioners but its accuracy is questionable. Multiple valuation inaccuracies are due to the unreliability of information used in valuation, inaccuracies comparison group selection, and use of individual multiple values. This study investigated the accuracy of valuation to examine factors that can increase the accuracy of the valuation of multiple ratios, that are discretionary accruals, the comparison group, and the composite of multiple valuation. These results indicate that multiple value adjustment method with discretionary accruals provides better accuracy, the industry comparator group method combined with the size and growth of companies also provide better accuracy. Composite of individual multiple valuation gives the best accuracy. If all of these factors combined, the accuracy of valuation of multiple ratios will give the best results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple" title="multiple">multiple</a>, <a href="https://publications.waset.org/abstracts/search?q=valuation" title=" valuation"> valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=accuracy" title=" accuracy"> accuracy</a> </p> <a href="https://publications.waset.org/abstracts/57424/improved-accuracy-of-ratio-multiple-valuation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57424.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">282</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">4741</span> Hormone Replacement Therapy (HRT) and Its Impact on the All-Cause Mortality of UK Women: A Matched Cohort Study 1984-2017</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurunnahar%20Akter">Nurunnahar Akter</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Kulinskaya"> Elena Kulinskaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Steel"> Nicholas Steel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilyas%20Bakbergenuly"> Ilyas Bakbergenuly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although Hormone Replacement Therapy (HRT) is an effective treatment in ameliorating menopausal symptoms, it has mixed effects on different health outcomes, increasing, for instance, the risk of breast cancer. Because of this, many symptomatic women are left untreated. Untreated menopausal symptoms may result in other health issues, which eventually put an extra burden and costs to the health care system. All-cause mortality analysis may explain the net benefits and risks of the HRT therapy. However, it received far less attention in HRT studies. This study investigated the impact of HRT on all-cause mortality using electronically recorded primary care data from The Health Improvement Network (THIN) that broadly represents the female population in the United Kingdom (UK). The study entry date for this study was the record of the first HRT prescription from 1984, and patients were followed up until death or transfer to another GP practice or study end date, which was January 2017. 112,354 HRT users (cases) were matched with 245,320 non-users by age at HRT initiation and general practice (GP). The hazards of all-cause mortality associated with HRT were estimated by a parametric Weibull-Cox model adjusting for a wide range of important medical, lifestyle, and socio-demographic factors. The multilevel multiple imputation techniques were used to deal with missing data. This study found that during 32 years of follow-up, combined HRT reduced the hazard ratio (HR) of all-cause mortality by 9% (HR: 0.91; 95% Confidence Interval, 0.88-0.94) in women of age between 46 to 65 at first treatment compared to the non-users of the same age. Age-specific mortality analyses found that combined HRT decreased mortality by 13% (HR: 0.87; 95% CI, 0.82-0.92), 12% (HR: 0.88; 95% CI, 0.82-0.93), and 8% (HR: 0.92; 95% CI, 0.85-0.98), in 51 to 55, 56 to 60, and 61 to 65 age group at first treatment, respectively. There was no association between estrogen-only HRT and women’s all-cause mortality. The findings from this study may help to inform the choices of women at menopause and to further educate the clinicians and resource planners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hormone%20replacement%20therapy" title="hormone replacement therapy">hormone replacement therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20imputations" title=" multiple imputations"> multiple imputations</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20care%20data" title=" primary care data"> primary care data</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20health%20improvement%20network%20%28THIN%29" title=" the health improvement network (THIN)"> the health improvement network (THIN)</a> </p> <a href="https://publications.waset.org/abstracts/137151/hormone-replacement-therapy-hrt-and-its-impact-on-the-all-cause-mortality-of-uk-women-a-matched-cohort-study-1984-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137151.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">170</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">4740</span> Higher Freshwater Fish and Sea Fish Intake Is Inversely Associated with Liver Cancer in Patients with Hepatitis B</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maomao%20Cao">Maomao Cao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and aims While the association between higher consumption of fish and lower liver cancer risk has been confirmed, however, the association between specific fish intake and liver cancer risk remains unknown. We aimed to identify the association between specific fish consumption and the risk of liver cancer. Methods: Based on a community-based seropositive hepatitis B cohort involving 18404 individuals, face to face interview was conducted by a standardized questionnaire to acquire baseline information. Three common fish types in this study were analyzed, including freshwater fish, sea fish, and small fish (shrimp, crab, conch, and shell). All participants received liver cancer screening, and possible cases were identified by CT or MRI. Multivariable logistic models were applied to estimate the odds ratio (OR) and 95% confidence intervals (CI). Multivariate multiple imputations were utilized to impute observations with missing values. Results: 179 liver cancer cases were identified. Consumption of freshwater fish and sea fish at least once a week had a strong inverse association with liver cancer risk compared with the lowest intake level, with an adjusted OR of 0.53 (95% CI, 0.38-0.75) and 0.38 (95% CI, 0.19-0.73), respectively. This inverse association was also observed after the imputation. There was no statistically significant association between intake of small fish and liver cancer risk (OR=0.58, 95%, CI 0.32-1.08). Conclusions: Our findings suggest that consumption of freshwater fish and sea fish at least once a week could reduce liver cancer risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-sectional%20study" title="cross-sectional study">cross-sectional study</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20intake" title=" fish intake"> fish intake</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer" title=" liver cancer"> liver cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a> </p> <a href="https://publications.waset.org/abstracts/139256/higher-freshwater-fish-and-sea-fish-intake-is-inversely-associated-with-liver-cancer-in-patients-with-hepatitis-b" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139256.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">273</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">4739</span> A More Powerful Test Procedure for Multiple Hypothesis Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shunpu%20Zhang">Shunpu Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a new multiple test called the minPOP test for testing multiple hypotheses simultaneously.

We show that these multiple tests have strong control of the family-wise error rate (FWER). A method for finding the p-values of the proposed tests after adjusting for multiplicity is also developed.

The multiple vertical plunging jets have jet impact angle of θ = 90O; whereas, multiple inclined plunging jets have jet impact angle of θ = 600. The results of the study suggests that mass transfer is higher for multiple jets, and inclined multiple plunging jets have up to 1.6 times higher mass transfer than vertical multiple plunging jets under similar conditions. The derived relationship, based on multi-linear regression approach, has successfully predicted the volumetric mass transfer coefficient (KLa) from operational parameters of multiple plunging jets with a correlation coefficient of 0.973, root mean square error of 0.002 and coefficient of determination of 0.946. The results suggests that predicted overall mass transfer coefficient is in good agreement with actual experimental values; thereby suggesting the utility of derived relationship based on multi-linear regression based approach and can be successfully employed in modelling mass transfer by multiple plunging jets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mass%20transfer" title="mass transfer">mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20plunging%20jets" title=" multiple plunging jets"> multiple plunging jets</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-linear%20regression" title=" multi-linear regression"> multi-linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20sciences" title=" earth sciences"> earth sciences</a> </p> <a href="https://publications.waset.org/abstracts/5905/multi-linear-regression-based-prediction-of-mass-transfer-by-multiple-plunging-jets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5905.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">462</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">4737</span> Genetic Algorithm Optimization of Multiple Resources for Multi-Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Samer%20Ezeldin">A.

Project managers have to face problems regarding management of cost, time and available resources of single projects and more problems arise when managing multiple projects. Most of the studies focused on optimization of resources for a single project, but, this paper will discuss the design and modeling of multiple resources optimization for multiple projects using Genetic Algorithm. Most of the companies in construction industry optimize the resources for single projects only, but with the presence of several mega projects in several developing countries running at the same time, there is a need for a model to enhance the efficiency of available resources and decreases the fluctuation as much as possible. The proposed model calculates the cost of each resource, tries to minimize the cost of extra resources as much as possible and generates the schedule of each project within a selected program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title="construction management">construction management</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20projects" title=" multiple projects"> multiple projects</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20resources" title=" multiple resources"> multiple resources</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/61061/genetic-algorithm-optimization-of-multiple-resources-for-multi-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61061.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">459</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">4736</span> Improved FP-Growth Algorithm with Multiple Minimum Supports Using Maximum Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elsayeda%20M.%20Elgaml">Elsayeda M.

The test statistic in the multiple comparisons is the proportion of efficient decision making units (DMUs) in a DEA model. Three methods of multiple comparisons test for proportions: multiple Z tests with Bonferroni correction, multiple tests in 2Xc crosstabulation and the Marascuilo procedure, are used in the proposed statistical procedure of iteratively eliminating the variables in a backward manner. Two simulation populations of moderately and lowly correlated variables are used to compare the results of the statistical procedure using three methods of multiple comparisons test for proportions with the hypothesis testing of the efficiency contribution measure. From the simulation results, it can be concluded that the proposed statistical procedure using multiple Z tests for proportions with Bonferroni correction clearly outperforms the proposed statistical procedure using the remaining two methods of multiple comparisons and the hypothesis testing of the efficiency contribution measure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bonferroni%20correction" title="Bonferroni correction">Bonferroni correction</a>, <a href="https://publications.waset.org/abstracts/search?q=efficient%20DMUs" title=" efficient DMUs"> efficient DMUs</a>, <a href="https://publications.waset.org/abstracts/search?q=Marascuilo%20procedure" title=" Marascuilo procedure"> Marascuilo procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=Pastor%20et%20al.%20method" title=" Pastor et al. method"> Pastor et al. method</a>, <a href="https://publications.waset.org/abstracts/search?q=2xc%20crosstabulation" title=" 2xc crosstabulation"> 2xc crosstabulation</a> </p> <a href="https://publications.waset.org/abstracts/62964/variable-selection-in-a-data-envelopment-analysis-model-by-multiple-proportions-comparison" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62964.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">310</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">4734</span> Sum Capacity with Regularized Channel Inversion in Multi-Antenna Downlink Systems under Equal Power Constraint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Attaullah%20Khawaja">Attaullah Khawaja</a>, <a href="https://publications.waset.org/abstracts/search?q=Amna%20Shabbir"> Amna Shabbir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Channel inversion is one of the simplest techniques for multiuser downlink systems with single-antenna users.

However, an increasingly controversial question is whether such systems can outperform the single best classifier, and if so, what form of multiple classifiers system yields the most significant benefit. Also, multi-target tracking detection using multiple sensors is an important research field in mobile techniques and military applications. In this paper, several multiple classifiers systems are evaluated in terms of their ability to predict a system’s failure or success for multi-sensor target tracking tasks. The Bristol Eden project dataset is utilised for this task.

The deployment of massive multiple-input-multiple-output technology guarantees broadband wireless networks with the use of base station antenna arrays to serve a large number of users on the same frequency and time-slot channels. In this work, we evaluate the performance of massive multiple-input-multiple-output systems (MIMO) systems in 5<sup>th</sup> generation cellular networks in terms of capacity and bit error rate. Several cases were considered and analyzed to compare the performance of massive MIMO systems while varying the number of antennas at both transmitting and receiving ends. We found that, unlike classical MIMO systems, reducing the number of transmit antennas while increasing the number of antennas at the receiver end provides a better solution to performance enhancement. In addition, enhanced orthogonal frequency division multiplexing and beam division multiple access schemes further improve the performance of massive MIMO systems and make them more reliable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beam%20division%20multiple%20access" title="beam division multiple access">beam division multiple access</a>, <a href="https://publications.waset.org/abstracts/search?q=D2D%20communication" title=" D2D communication"> D2D communication</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20OFDM" title=" enhanced OFDM"> enhanced OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=fifth%20generation%20broadband" title=" fifth generation broadband"> fifth generation broadband</a>, <a href="https://publications.waset.org/abstracts/search?q=massive%20MIMO" title=" massive MIMO"> massive MIMO</a> </p> <a href="https://publications.waset.org/abstracts/96696/performance-analysis-in-5th-generation-massive-multiple-input-multiple-output-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96696.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">258</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">4729</span> Efficacy and Safety of Electrical Vestibular Stimulation on Adults with Symptoms of Insomnia: A Double-Blind, Randomized, Sham-Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teris%20Cheung">Teris Cheung</a>, <a href="https://publications.waset.org/abstracts/search?q=Joyce%20Yuen%20Ting%20Lam"> Joyce Yuen Ting Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwan%20Hin%20Fong"> Kwan Hin Fong</a>, <a href="https://publications.waset.org/abstracts/search?q=Calvin%20Pak-Wing%20Cheng"> Calvin Pak-Wing Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Sittlington"> Julie Sittlington</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Tao%20Xiang"> Yu-Tao Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Man%20Ho%20Li"> Tim Man Ho Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Insomnia is one of the most common health problems in the general population. Insomnia can be acute, intermittent, and become chronic, often due to comorbidity with other physical and mental health conditions. Although there are conventional pharmaceutical and psychotherapeutic treatments to treat symptoms of insomnia, however; there is no robust and novel randomized controlled trial (RCT) using transdermal neurostimulation on individuals with insomnia symptoms. This gives us the impetus to execute the first nationwide RCT. Aim: To evaluate the efficacy of Electrical Vestibular Stimulation (VeNS) on individuals with insomnia in Hong Kong. Design: This study was a two-armed, double blinded, randomized, sham-controlled trial. Sampling: 60 community-dwelling adults aged 18 and 60 years with moderate insomnia symptoms or above (Insomnia Severity Index > 14) were recruited. All subjects were computerized randomized into either the active VeNS group or the sham VeNS group on a 1:1 ratio. Intervention: All participants received a home-use VeNS device and used 30-min VeNS sessions during five consecutive days across a 4-week period (total treatment hours: 10). Baseline measurements and post-VeNS evaluation of the psychological outcomes, including 1) insomnia severity, 2) sleep quality, and 3) quality of life were investigated. The short-and long-term sustainability of the VeNS intervention was assessed immediately after poststim and at a 1-month and 3-month follow-up period. Data analysis: A mixed GEE model was used to analyze the repeated measures data. Missing data were managed by multiple imputations. The level of significance was set to p < 0.05. Significance of the study: This is the first trial to examine the efficacy and safety of VeNS among adults with insomnia symptoms in Hong Kong. Findings that emerged were used to determine whether this VeNS device can be considered a self-help technological device to reduce the severity of insomnia in the community setting and to reduce the global disease burden.

Given these robust evidences, TPS might be an adjunct treatment options in neuropsychiatric disorders, for example, autism spectrum disorder (ASD) – which is a common neurodevelopmental disorder in children. This trial aimed to investigate the effects of TPS on right temporoparietal junction, a key node for social cognition for Autism Spectrum Disorder (ASD), and to examine the association between TPS, executive functions and social functions. Design: This trial adopted a two-armed (verum TPS group vs. sham TPS group), double-blinded, randomized, sham-controlled design. Sampling: 32 subjects aged between 12 and 17, diagnosed with ASD were recruited. All subjects were computerized randomized into either verum TPS group or the sham TPS group on a 1:1 ratio. All subjects undertook functional MRI before and after the TPS interventions. Intervention: Six 30-min TPS sessions were administered to subjects in 2 weeks’ time on alternate days assessing neural connectivity changes. Baseline measurements and post-TPS evaluation of the ASD symptoms, executive functions, and social functions were conducted. Participants were followed up at 2-weeks, at 1-month and 3-month, assessing the short-and long-term sustainability of the TPS intervention. Data analysis: Generalized Estimating Equations with repeated measures were used to analyze the group and time difference. Missing data were managed by multiple imputations. The level of significance was set at p < 0.05. To our best knowledge, this is the first study evaluating the efficacy and safety of TPS among adolescents with ASD in Hong Kong and nationwide. Results emerging from this study will develop insight on whether TPS can be used as an adjunct treatment on ASD in neuroscience and clinical psychiatry.

This is because the user lacks focus on visualizing the contents due to the interaction mechanisms whereby multiple markers may need to be used to perform a particular function. In this research, we have designed a novel TUI user interface where multiple functions could be triggered similar to a natural keyboard thus allowing user to focus more on its digital contents such as 2D/3D, text input, animation and sound. Test results of the user interface with potential users and HCI experts revealed that the multiple functions user interface was new, preferred and appreciated more as opposed to marker based user interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multimedia" title="multimedia">multimedia</a>, <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title=" augmented reality"> augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering" title=" engineering"> engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20interface" title=" user interface"> user interface</a>, <a href="https://publications.waset.org/abstracts/search?q=visualization" title=" visualization"> visualization</a> </p> <a href="https://publications.waset.org/abstracts/34793/interactive-multiple-functions-user-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34793.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">449</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">4726</span> An Investigation the Effectiveness of Emotion Regulation Training on the Reduction of Cognitive-Emotion Regulation Problem in Patients with Multiple Sclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahboobeh%20Sadeghi">Mahboobeh Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Izadi%20Khah"> Zahra Izadi Khah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansour%20Hakim%20Javadi"> Mansour Hakim Javadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Gholamali%20Lavasani"> Masoud Gholamali Lavasani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Since there is a relation between psychological and physiological factors, the aim of this study was to examine the effect of Emotion Regulation training on cognitive emotion regulation problem in patients with Multiple Sclerosis(MS) Method: In a randomized clinical trial thirty patients diagnosed with Multiple Sclerosis referred to state welfare organization were selected.

Engine parts are subject to extremely high standards as they can impact the performance of the engine. Therefore, it is essential to analyze these databases to better understand the influence of the different parameters on the engine's performance. Self-organizing maps are unsupervised neural networks which achieve two tasks simultaneously: they visualize high-dimensional data by projection onto a 2-dimensional map and provide clustering of the data. This technique has become very popular for data exploration since it provides easily interpretable results and a meaningful global view of the data. As such, self-organizing maps are usually applied to aircraft engine condition monitoring. As databases in this field are huge and complex, they naturally contain multiple missing entries for various reasons. The classical Kohonen algorithm to compute self-organizing maps is conceived for complete data only. A naive approach to deal with partially observed data consists in deleting items or variables with missing entries. However, this requires a sufficient number of complete individuals to be fairly representative of the population; otherwise, deletion leads to a considerable loss of information. Moreover, deletion can also induce bias in the analysis results. Alternatively, one can first apply a common imputation method to create a complete dataset and then apply the Kohonen algorithm. However, the choice of the imputation method may have a strong impact on the resulting self-organizing map. Our approach is to address simultaneously the two problems of computing a self-organizing map and imputing missing values, as these tasks are not independent. In this work, we propose an extension of self-organizing maps for partially observed data, referred to as missSOM. First, we introduce a criterion to be optimized, that aims at defining simultaneously the best self-organizing map and the best imputations for the missing entries. As such, missSOM is also an imputation method for missing values. To minimize the criterion, we propose an iterative algorithm that alternates the learning of a self-organizing map and the imputation of missing values. Moreover, we develop an accelerated version of the algorithm by entwining the iterations of the Kohonen algorithm with the updates of the imputed values. This method is efficiently implemented in R and will soon be released on CRAN. Compared to the standard Kohonen algorithm, it does not come with any additional cost in terms of computing time. Numerical experiments illustrate that missSOM performs well in terms of both clustering and imputation compared to the state of the art. In particular, it turns out that missSOM is robust to the missingness mechanism, which is in contrast to many imputation methods that are appropriate for only a single mechanism. This is an important property of missSOM as, in practice, the missingness mechanism is often unknown. An application to measurements on one type of part is also provided and shows the practical interest of missSOM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=imputation%20method%20of%20missing%20data" title="imputation method of missing data">imputation method of missing data</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20observed%20data" title=" partially observed data"> partially observed data</a>, <a href="https://publications.waset.org/abstracts/search?q=robustness%20to%20missingness%20mechanism" title=" robustness to missingness mechanism"> robustness to missingness mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=self-organizing%20maps" title=" self-organizing maps"> self-organizing maps</a> </p> <a href="https://publications.waset.org/abstracts/142434/self-organizing-maps-for-exploration-of-partially-observed-data-and-imputation-of-missing-values-in-the-context-of-the-manufacture-of-aircraft-engines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4724</span> Performance Analysis of M-Ary Pulse Position Modulation in Multihop Multiple Input Multiple Output-Free Space Optical System over Uncorrelated Gamma-Gamma Atmospheric Turbulence Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hechmi%20Saidi">Hechmi Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Hamdi"> Noureddine Hamdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of Decode and Forward (DF) multihop Free Space Optical ( FSO) scheme deploying Multiple Input Multiple Output (MIMO) configuration under Gamma-Gamma (GG) statistical distribution, that adopts M-ary Pulse Position Modulation (MPPM) coding, is investigated.

Traditionally, the decomposed LP consists of one LP master problem and one LP subproblem. The master problem and the subproblem is solved alternatively by exchanging the dual prices of the master problem and the proposals of the subproblem until the LP is solved. It is well known that convergence is slow with a long tail of near-optimal solutions (asymptotic convergence). Hence, the performance of DW-LP highly depends upon the number of decomposition steps. If the decomposition steps can be greatly reduced, the performance of DW-LP can be improved significantly. To reduce the number of decomposition steps, one of the methods is to increase the number of proposals from the subproblem to the master problem. To do so, we propose to add a quadratic approximation function to the LP subproblem in order to develop a set of approximate-LP subproblems (multiple subproblems). Consequently, in each decomposition step, multiple subproblems are solved for providing multiple proposals to the master problem. The number of decomposition steps can be reduced greatly. Note that each approximate-LP subproblem is nonlinear programming, and solving the LP subproblem must faster than solving the nonlinear multiple subproblems. Hence, using multiple subproblems in DW-LP is the tradeoff between the number of approximate-LP subproblems being formed and the decomposition steps. In this paper, we derive the corresponding algorithms and provide some simple computational results. Some properties of the resulting algorithms are also given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=approximate%20subproblem" title="approximate subproblem">approximate subproblem</a>, <a href="https://publications.waset.org/abstracts/search?q=Dantzig-Wolfe%20decomposition" title=" Dantzig-Wolfe decomposition"> Dantzig-Wolfe decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale%20models" title=" large-scale models"> large-scale models</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20subproblems" title=" multiple subproblems"> multiple subproblems</a> </p> <a href="https://publications.waset.org/abstracts/110435/a-study-of-using-multiple-subproblems-in-dantzig-wolfe-decomposition-of-linear-programming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110435.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">166</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">4722</span> Multiple-Lump-Type Solutions of the 2D Toda Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian-Ping%20Yu">Jian-Ping Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Xiu%20Ma"> Wen-Xiu Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Li%20Sun"> Yong-Li Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaudry%20Masood%20Khalique"> Chaudry Masood Khalique</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a 2d Toda equation is studied, which is a classical integrable system and plays a vital role in mathematics, physics and other areas.

This is particularly relevant for gestational carriers since they usually do not have infertility issues. Single embryo transfer (SET) therefore has been encouraged to assist reproductive technology (ART) practice in order to reduce multiple pregnancies. Objectives: This systematic review aims to investigate the pregnancy and birth outcomes of SET and multiple ET in surrogacy arrangements. Search methods: This study is a systematic review. Electronic databases were searched from CINAHL, Medline, Embase, Scopus and ProQuest for studies from 1980 to 2017. Cross-references and national ART reports were also manual searchings. Articles without restriction of English language and study types were accessed. Carrier cycles involving in SET and multiple ET were identified in database searching. The main outcome measures including clinical pregnancy, live delivery and multiple deliveries per gestational carrier cycle were compared between SET and multiple ET. Mantel-Haenzel risk ratios (RRs) with 95% confidence intervals (CIs), using the numbers of outcome events in SET and multiple ET of each study were calculated suing RevMan5.3. Outcomes: The search returned 97 articles of which 5 met the inclusion criteria. Approximately 50% of carrier cycles were transferred a single embryo and 50% were transferred more than one embryo. The clinical pregnancy rate (CPR) was 39% for SET and 53% for multiple ET, which was not significantly different with RR = 0.83 (95% CI: 0.67-1.03). The live delivery rate was 33% for SET and 57% for multiple ET which was not significantly different with RR = 0.78 (95% CI: 0.61-1.00). The multiple delivery rate per carrier was greater risks in the multiple ET carrier cycles (RR =0.4, 95% CI: 0.01-0.26). There were 104 sets of twins (including one set of twins selectively reduced from triplets to twins) and 1 set of triples in the multiple ET carrier cycle. In the SET carrier cycles, there were 2 sets of twins. Significance of the study: SET should be advocated among surrogate carriers to prevent multiple pregnancies and subsequent adverse outcomes for both carrier and baby. Surrogacy practice should be reviewed and surrogate carriers should be fully informed of the risk of adverse maternal and birth outcome of multiple pregnancies due to multiple embryo transfers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assisted%20reproduction" title="assisted reproduction">assisted reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=birth%20outcomes" title=" birth outcomes"> birth outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=carrier" title=" carrier"> carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=gestational%20surrogacy" title=" gestational surrogacy"> gestational surrogacy</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20embryo%20transfer" title=" multiple embryo transfer"> multiple embryo transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20pregnancy" title=" multiple pregnancy"> multiple pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy%20outcomes" title=" pregnancy outcomes"> pregnancy outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20embryo%20transfer" title=" single embryo transfer"> single embryo transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=surrogate%20mother" title=" surrogate mother"> surrogate mother</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a> </p> <a href="https://publications.waset.org/abstracts/97795/pregnancy-and-birth-outcomes-of-single-versus-multiple-embryo-transfer-in-gestational-surrogacy-arrangements-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97795.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">404</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">4720</span> Characterization of Onboard Reliable Error Correction Code FORSDRAM Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Pitcheswara%20Rao">N.

In order to overcome this drawback i.e., to increase speed and latency we are using reed-Muller code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SEC-DED" title="SEC-DED">SEC-DED</a>, <a href="https://publications.waset.org/abstracts/search?q=BCH%20code" title=" BCH code"> BCH code</a>, <a href="https://publications.waset.org/abstracts/search?q=Reed-Solomon%20code" title=" Reed-Solomon code"> Reed-Solomon code</a>, <a href="https://publications.waset.org/abstracts/search?q=Reed-Muller%20code" title=" Reed-Muller code"> Reed-Muller code</a> </p> <a href="https://publications.waset.org/abstracts/32965/characterization-of-onboard-reliable-error-correction-code-for-sdram-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32965.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">429</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">4718</span> Evaluation of Aggregate Risks in Sustainable Manufacturing Using Fuzzy Multiple Attribute Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gopinath%20Rathod">Gopinath Rathod</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Puranik"> Vinod Puranik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainability is regarded as a key concept for survival in the competitive scenario. Industrial risk and diversification of risk type’s increases with industrial developments. In the context of sustainable manufacturing, the evaluation of risk is difficult because of the incomplete information and multiple indicators. Fuzzy Multiple Attribute Decision Method (FMADM) has been used with a three level hierarchical decision making model to evaluate aggregate risk for sustainable manufacturing projects. A case study has been presented to reflect the risk characteristics in sustainable manufacturing projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20manufacturing" title="sustainable manufacturing">sustainable manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregate%20risk" title=" aggregate risk"> aggregate risk</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20multiple%20attribute%20decision%20method" title=" fuzzy multiple attribute decision method"> fuzzy multiple attribute decision method</a> </p> <a href="https://publications.waset.org/abstracts/17324/evaluation-of-aggregate-risks-in-sustainable-manufacturing-using-fuzzy-multiple-attribute-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17324.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">520</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">4717</span> Aerodynamic Analysis of Multiple Winglets for Aircrafts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Pooja%20Pragati">S.

It is designed to provide an optimum performance of a winglet from conventional designs. In preparing for a mechanical design, aspects such as shape, dimensions are analyzed to yield a huge amount of reduction in fuel consumption and increased performance. Owing to its simplicity of application and effectiveness we believe that it will enable us to consider its enhanced version for the grid effect of the staggered multiple winglets on the deflected mass flow of the wing system. The objective of the analysis were to compare the aerodynamic characteristics of two winglet configuration and to investigate the performance of two winglets shape simulated at selected cant angle of 0,45,60 degree. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20winglets" title="multiple winglets">multiple winglets</a>, <a href="https://publications.waset.org/abstracts/search?q=induced%20drag" title=" induced drag"> induced drag</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamics%20analysis" title=" aerodynamics analysis"> aerodynamics analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20speed%20aircrafts" title=" low speed aircrafts"> low speed aircrafts</a> </p> <a href="https://publications.waset.org/abstracts/29408/aerodynamic-analysis-of-multiple-winglets-for-aircrafts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29408.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">480</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">4716</span> The Impact of a Lower Health Literacy in the Self-Management of Patients with a Multiple Sclerosis: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helga%20Martins">Helga Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Id%C3%A1lia%20Matias"> Idália Matias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background:Multiple sclerosis is a chronic inflammatory autoimmune demyelinating disease that affects young adults. Multiple sclerosis is a chronic disease in which the patient needs to self-manage the disease and the therapeutic regimen. Consequently, the promotion of health literacy assumes a relevant role for the accessibility, understanding, and use of information in order to promote and maintain the health of patients with multiple sclerosis. Aim: To determine the impact of lower health literacy in the self-management of patients with a multiple sclerosis. Methods: Literature review based on a search on the following electronic databases: CINAHLand MEDLINE; comprising all results published between September 2016 and September 2021. The search strategy was: (“Self-management [MeSH]” AND “Multiple sclerosis[MeSH]”AND “Health literacy[MeSH]”). The inclusion criteria were: original papers reporting about multiple sclerosis patients; participants with age above 18 years old, written in English, Spanish, French, or Portuguese. Two independent reviewers have done the screening and analysis of the results. 38 citations were identified, and after duplicates removal, a total of 25 results were screened; 14 were included after the application of the inclusion criteria. Results: The lower health literacy in the self-management of patients with a multiple sclerosis is related toless healthy choices, riskier health behavior, poor health outcomes, decreased of adhering to the therapeutic regimen after discharge, less self-management of chronic illness, and increased the time of hospitalization. Conclusion: Inadequate levels of health literacy contribute to poor health outcomes, unsuccessful self-management of chronic illness, and inadequate adherence to the therapeutic regimen. Therefore, health literacy is important for health policy and the healthcare services, as it can be understood as a mediator of self-management of multiple sclerosis disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20literacy" title="health literacy">health literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title=" multiple sclerosis"> multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=review" title=" review"> review</a>, <a href="https://publications.waset.org/abstracts/search?q=self-management" title=" self-management"> self-management</a> </p> <a href="https://publications.waset.org/abstracts/143996/the-impact-of-a-lower-health-literacy-in-the-self-management-of-patients-with-a-multiple-sclerosis-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143996.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">154</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">4715</span> A Golay Pair Based Synchronization Algorithm for Distributed Multiple-Input Multiple-Output System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weizhi%20Zhong">Weizhi Zhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyi%20Lu"> Xiaoyi Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Xu"> Lei Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to solve the problem of inaccurate synchronization for distributed multiple-input multiple-output (MIMO) system in multipath environment, a golay pair aided timing synchronization method is proposed in this paper. A new synchronous training sequence based on golay pair is designed. By utilizing the aperiodic auto-correlation complementary property of the new training sequence, the fine timing point is obtained at the receiver. Simulation results show that, compared with the tradition timing synchronization approaches, the proposed algorithm can provide high accuracy in synchronization, especially under multipath condition.
