However, mathematical induction (MI) stands out to be one of the most powerful proof techniques for proving hypotheses, theorems, and new results. There are variations of mathematical induction-based proof techniques, which are broadly classified into three categories, such as structural induction (SI), weak induction (WI), and strong induction (SI). In this expository paper, several different variants of the mathematical induction techniques are explored, and the specific scenarios are discussed where a specific induction technique stands out to be more advantageous as compared to other induction strategies. Also, the essential difference among the variants of mathematical induction are explored. The points of separation among mathematical induction, recursion, and logical deduction are precisely analyzed, and the relationship among variations of recurrence relations, and mathematical induction are being explored. In this context, the application of recurrence relations, and mathematical inductions are considered together in a single framework for codewords over a given alphabet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alphabet" title="alphabet">alphabet</a>, <a href="https://publications.waset.org/abstracts/search?q=codeword" title=" codeword"> codeword</a>, <a href="https://publications.waset.org/abstracts/search?q=deduction" title=" deduction"> deduction</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical" title=" mathematical"> mathematical</a>, <a href="https://publications.waset.org/abstracts/search?q=induction" title=" induction"> induction</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrence%20relation" title=" recurrence relation"> recurrence relation</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20induction" title=" strong induction"> strong induction</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20induction" title=" structural induction"> structural induction</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20induction" title=" weak induction"> weak induction</a> </p> <a href="https://publications.waset.org/abstracts/116467/variants-of-mathematical-induction-as-strong-proof-techniques-in-theory-of-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116467.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">164</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">18741</span> Diagnosis of Induction Machine Faults by DWT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Akbari">Hamidreza Akbari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, for detection of inclined eccentricity in an induction motor, time–frequency analysis of the stator startup current is carried out.

On the other hand, the high gas storage capacity of hydrate may be utilized for natural gas storage and transport. Research on the promotion of hydrate formation, as related to natural gas storage and transport, has received relatively little attention. The primary objective of this study is to gain a better understanding of the effects of ionic surfactants, particularly their molecular structures and concentration, on the formation of tetrahydrofuran (THF) hydrate, which is often used as a model hydrate former for screening hydrate promoters or inhibitors. The surfactants studied were sodium n-dodecyl sulfate (SDS), sodium n-hexadecyl sulfate (SHS). Our results show that, at concentrations below the solubility limit, the induction time decreases with increasing surfactant concentration. At concentrations near or above the solubility, however, the surfactant concentration no longer has any effect on the induction time. These observations suggest that the effect of surfactant on THF hydrate formation is associated with surfactant monomers, not the formation of micelle as previously reported. The lowest induction time (141.25 ± 21 s, n = 4) was observed in a solution containing 7.5 mM SDS. The induction time decreases by a factor of three at concentrations near or above the solubility, compared to that without surfactant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tetrahydrofuran" title="tetrahydrofuran">tetrahydrofuran</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrate" title=" hydrate"> hydrate</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactant" title=" surfactant"> surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20time" title=" induction time"> induction time</a>, <a href="https://publications.waset.org/abstracts/search?q=monomers" title=" monomers"> monomers</a>, <a href="https://publications.waset.org/abstracts/search?q=micelle" title=" micelle"> micelle</a> </p> <a href="https://publications.waset.org/abstracts/2282/investigate-the-effects-of-anionic-surfactant-on-thf-hydrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2282.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">410</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">18739</span> A Study on Analysis of Magnetic Field in Induction Generator for Small Francis Turbine Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Kwan%20Choi">Young-Kwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Sang%20Jeong"> Han-Sang Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeon-Ho%20Ok"> Yeon-Ho Ok</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Choi"> Jae-Ho Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to verify validity of design by testing output of induction generator through finite element analysis before manufacture of induction generator designed.

The DTC is an excellent solution for general- purpose induction drives in very wide range the short sampling time required by the TC schemes makes them suited to a very fast torque and flux controlled drives as well the simplicity of the control algorithm. DTC is inherently a motion sensorless control method. The RST regulator can improve the double star induction motor performance in terms of overshoot, rapidity, cancellation of disturbance, and capacity to maintain a high level of performance.

The mathematical analysis of this problem in most cases is very difficult and it is reduced to simple cases. Another knowledge of induction heating systems is generated in production environments, but these trial-error procedures are long and expensive. The numerical models of induction heating problem are another approach to reduce abovementioned drawbacks. This paper deals with the simulation model of induction heating problem.

In this case "Electro Magnetic Induction" is used where it is known that when two separate circuits are connected to the electro magnet and on application of electric current through the one circuit in to the coil induces magnetic fields which repels the other circuit.( Faraday's law of Electromagnetic Induction). Basically a Spacecraft is used to attach a large sheet of aluminum on to the surface of the asteroid, the Spacecraft acts as an electro magnet and the induced magnetic field would eventually repel the aluminum intern repelling the asteroid. This method would take less time as compared to use of gravity( which requires a larger spacecraft and process will take a long time). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asteroids" title="asteroids">asteroids</a>, <a href="https://publications.waset.org/abstracts/search?q=electro%20magnetic%20induction" title=" electro magnetic induction"> electro magnetic induction</a>, <a href="https://publications.waset.org/abstracts/search?q=gravity" title=" gravity"> gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=electro%20magnetic%20tractor" title=" electro magnetic tractor "> electro magnetic tractor </a> </p> <a href="https://publications.waset.org/abstracts/20948/electro-magnetic-tractor-e-m-tractor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20948.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">492</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">18731</span> Comparison of Cervical Length Using Transvaginal Ultrasonography and Bishop Score to Predict Succesful Induction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lubena%20Achmad">Lubena Achmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Herman%20Kristanto"> Herman Kristanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Julian%20Dewantiningrum"> Julian Dewantiningrum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The Bishop score is a standard method used to predict the success of induction. This examination tends to be subjective with high inter and intraobserver variability, so it was presumed to have a low predictive value in terms of the outcome of labor induction. Cervical length measurement using transvaginal ultrasound is considered to be more objective to assess the cervical length. Meanwhile, this examination is not a complicated procedure and less invasive than vaginal touché. Objective: To compare transvaginal ultrasound and Bishop score in predicting successful induction. Methods: This study was a prospective cohort study. One hundred and twenty women with singleton pregnancies undergoing induction of labor at 37 – 42 weeks and met inclusion and exclusion criteria were enrolled in this study. Cervical assessment by both transvaginal ultrasound and Bishop score were conducted prior induction. The success of labor induction was defined as an ability to achieve active phase ≤ 12 hours after induction. To figure out the best cut-off point of cervical length and Bishop score, receiver operating characteristic (ROC) curves were plotted. Logistic regression analysis was used to determine which factors best-predicted induction success. Results: This study showed significant differences in terms of age, premature rupture of the membrane, the Bishop score, cervical length and funneling as significant predictors of successful induction. Using ROC curves found that the best cut-off point for prediction of successful induction was 25.45 mm for cervical length and 3 for Bishop score. Logistic regression was performed and showed only premature rupture of membranes and cervical length ≤ 25.45 that significantly predicted the success of labor induction. By excluding premature rupture of the membrane as the indication of induction, cervical length less than 25.3 mm was a better predictor of successful induction. Conclusion: Compared to Bishop score, cervical length using transvaginal ultrasound was a better predictor of successful induction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bishop%20Score" title="Bishop Score">Bishop Score</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20length" title=" cervical length"> cervical length</a>, <a href="https://publications.waset.org/abstracts/search?q=induction" title=" induction"> induction</a>, <a href="https://publications.waset.org/abstracts/search?q=successful%20induction" title=" successful induction"> successful induction</a>, <a href="https://publications.waset.org/abstracts/search?q=transvaginal%20sonography" title=" transvaginal sonography "> transvaginal sonography </a> </p> <a href="https://publications.waset.org/abstracts/65273/comparison-of-cervical-length-using-transvaginal-ultrasonography-and-bishop-score-to-predict-succesful-induction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65273.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">325</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">18730</span> Risk Factors for Post-Induction Hypotension Among Elderly Patients Undergoing Elective Non-Cardiac Surgery Under General Anesthesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karuna%20Sutthibenjakul">Karuna Sutthibenjakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunisa%20Chatmongkolchart"> Sunisa Chatmongkolchart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Postinduction hypotension is common and occurs more often in elderly patients. We aimed to determine risk factors for hypotension after induction among elderly patients (aged 65 years and older) who underwent elective non-cardiac surgery under general anesthesia. Methods: This cohort study analyzed from 580 data between December 2017 and July 2018 at a tertiary university hospital in south of Thailand. Hypotension is defined as more than 30% decrease mean arterial pressure from baseline after induction within 20 minutes or the use of vasopressive agent to treat low blood pressure. Intraoperative parameters were blood pressure and heart rate at T0, TEI, T5, T10, T15 and T20 (immediately after arrival at operating room, time after intubation, 5, 10, 15 and 20 minutes after intubation) respectively. Results: The median age was 72.5 (68, 78) years. A prevalence of post-induction hypotension was 64.8%. The highest prevalence (39.7%) was at 15 minutes after intubation. The association of post-induction hypotension is rising with diuretic drug as preoperative medication (P-value=0.016), hematocrit level (P-value=0.031) and the degree of hypertension immediately after arrival at operating room (P-value<0.001). Increasing fentanyl dosage during induction was associated with hypotension at intubation time (P-value<0.01) and 5 minutes after intubation (P-value<0.001). There was no statistically significant difference in the increasing propofol dosage. Conclusion: The degree of hypertension immediately after arrival at operating room and increasing fentanyl dosage were a significant risk factors for postinduction hypotension in elderly patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title="risk factors">risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=post-induction" title=" post-induction"> post-induction</a>, <a href="https://publications.waset.org/abstracts/search?q=hypotension" title=" hypotension"> hypotension</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly" title=" elderly"> elderly</a> </p> <a href="https://publications.waset.org/abstracts/102038/risk-factors-for-post-induction-hypotension-among-elderly-patients-undergoing-elective-non-cardiac-surgery-under-general-anesthesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102038.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">18729</span> Issues on Optimizing the Structural Parameters of the Induction Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marinka%20K.%20Baghdasaryan">Marinka K.

Delay in IOL has been defined as delay in the time it takes a woman to wait for induction after her cervix is assessed to be favorable. Opinions vary on the acceptable time the patient is allowed to wait for once the cervix is adjudged ripe for induction. What has been considered a benchmark is a delay of up to 12 hours. There is evidence that delay in IOL is associated with adverse outcomes. Aim: To determine the number of women experiencing delay in induction of labor and their outcomes. Method: This audit was retrospective and observational. It included women who had induction of labor in the month of October 2023 in two hospitals. Clinical data was collected from electronic medical records into an Excel sheet for analysis. Women had cervical ripening as inpatient or outpatient. The primary objective was to determine the number of women experiencing delay in induction of labor, while the secondary objective was to outcome these women. Result: 136 women had IOL. The least percentage of data retrieved for any parameter was 80%. The mean gestational age at IOL was 278.26 days. The mean waiting time was 905.34mins. Seventy-five women had their IOL at the Royal Infirmary of Edinburgh (RIE), fifty-seven at St. John’s Hospital (SJH), and three women were transferred from RIE to SJH. The preferred method of cervical ripening was balloon closely followed by prostaglandin. Twenty-seven women did not require cervical ripening and had their process started with amniotomy. Prostaglandin was the method of choice of cervical ripening at RIE, while balloon was preferred in SJH. Of the thirty-five women found to be suitable for outpatient cervical ripening, thirteen had outpatient ripening. There was a significant increase in the number of women undergoing outpatient cervical ripening at RIE from 10.5% in April 2022 to 42.9%. The preferred method for outpatient cervical ripening at the RIE was balloon, while it was prostaglandin for SJH. These were contradictory to the preferred method of inpatient cervical ripening at both centers. The average waiting time for IOL at RIE, 1166.92mins, is more than double that of SJH, 442.93mins, and far exceed 12hours, which is the proposed benchmark. The waiting time tends to be shorter with prostaglandin. Out of the women that had outpatient cervical ripening 63.6% had to wait for more than 12hrs before being induced while it was 36.1% for women that had inpatient cervical ripening. Overall, 38.5% women waited for more than 12 hours before having their induction. A lesser proportion of the women who waited for more than 12 hours had caesarean section, assisted vaginal delivery, and postpartum hemorrhage, whereas a greater proportion had spontaneous vaginal delivery and intrapartum or postpartum infection. Conclusion: A significant number of the women included in the study experienced delay in their induction process, and this was associated with an increased occurrence of intrapartum or postpartum infection. Outpatient cervical ripening contributed to delay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delay%20in%20induction%20of%20labor" title="delay in induction of labor">delay in induction of labor</a>, <a href="https://publications.waset.org/abstracts/search?q=inpatient" title=" inpatient"> inpatient</a>, <a href="https://publications.waset.org/abstracts/search?q=outpatient" title=" outpatient"> outpatient</a>, <a href="https://publications.waset.org/abstracts/search?q=intrapartum" title=" intrapartum"> intrapartum</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum" title=" postpartum"> postpartum</a>, <a href="https://publications.waset.org/abstracts/search?q=infection" title=" infection"> infection</a> </p> <a href="https://publications.waset.org/abstracts/191242/delay-in-induction-of-labour-at-two-hospitals-in-southeast-scotland-outcomes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191242.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">22</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">18724</span> Outcome of Induction of Labour by Cervical Ripening with an Osmotic Dilator in a District General Hospital </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Wahid%20Uddin">A.

The study was a clinical intervention with an osmotic dilator followed by prospective observation. The aim was to calculate the percentage of women who had successful cervical ripening using modified BISHOP score as evidenced by artificial rupture of membrane. The study also estimated the delivery interval following a single administration of osmotic dilators. Randomly selected patients booked for induction of labour accepting the intervention were included in the study. The study population comprised singleton term pregnancy, cephalic presentation, intact membranes with a modified BISHOP score of less than 6. Initial sample recruited was 30, but 6 patients left the study and the study was concluded on 24 patients. The data were collected in a pre-designed questionnaire and analysis were expressed in percentages along with using mean value for continuous variables. In 70 % of cases, artificial rupture of the membrane was possible and the mean time from insertion of the osmotic dilator to the delivery interval was 30 hours. The study concluded that an osmotic dilator could be a suitable alternative for hormone-based induction of labour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dilator" title="dilator">dilator</a>, <a href="https://publications.waset.org/abstracts/search?q=induction" title=" induction"> induction</a>, <a href="https://publications.waset.org/abstracts/search?q=labour" title=" labour"> labour</a>, <a href="https://publications.waset.org/abstracts/search?q=osmotic" title=" osmotic "> osmotic </a> </p> <a href="https://publications.waset.org/abstracts/137883/outcome-of-induction-of-labour-by-cervical-ripening-with-an-osmotic-dilator-in-a-district-general-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137883.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">138</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">18723</span> An Evaluation of the Effectiveness of Health and Safety Induction Practices in the Zambian Construction Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Mutwale-Ziko">Josephine Mutwale-Ziko</a>, <a href="https://publications.waset.org/abstracts/search?q=Nonde%20Lushinga"> Nonde Lushinga</a>, <a href="https://publications.waset.org/abstracts/search?q=Inonge%20Akakandelwa"> Inonge Akakandelwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study discusses the effectiveness of health and safety induction practices on construction sites against the background of the Zambian construction industry experience. The research design included the literature review of relevant literature. Questionnaires and interviews were administered to regulatory bodies, health, and safety personnel. Observation was also employed on construction sites to assess the health and safety practices being used. Health and safety in the construction industry are not something to be ignored or overlooked. The construction industry needs to take heed of the serious consequences of inadequate health and safety induction practices. The implications of inadequate health and safety induction procedures included among others threats to profitability, corporate social responsibility and increased turnover of the workforce leading to poor productivity. Adequate health and safety practices can improve the health and wellbeing of employees, reduce financial implications on firms and encourage productivity on construction sites. Despite this, accidents are still prevalent on construction sites in Zambia. The overall result of this research denotes that the implementation of health and safety induction practices is inadequate, as indicated by the negligent and non-adherent attitude to health and safety induction aspects on the sites by most stakeholders on construction sites. Therefore, health and safety induction practices are ineffective as preventive measures for reduction of accidents on construction sites in Zambia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accidents" title="accidents">accidents</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20and%20safety" title=" health and safety"> health and safety</a>, <a href="https://publications.waset.org/abstracts/search?q=inadequate" title=" inadequate"> inadequate</a>, <a href="https://publications.waset.org/abstracts/search?q=induction" title=" induction"> induction</a> </p> <a href="https://publications.waset.org/abstracts/65770/an-evaluation-of-the-effectiveness-of-health-and-safety-induction-practices-in-the-zambian-construction-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65770.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">18722</span> Evaluation of Non-Pharmacological Method-Transcervical Foley Catheter and Misoprostol to Intravaginal Misoprostol for Preinduction Cervical Ripening</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krishna%20Dahiya">Krishna Dahiya</a>, <a href="https://publications.waset.org/abstracts/search?q=Esha%20Charaya"> Esha Charaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Induction of labour is a common obstetrical intervention. Around 1 in every 4 patient undergo induction of labour for different indications Purpose: To study the efficacy of the combination of Foley bulb and vaginal misoprostol in comparison to vaginal misoprostol alone for cervical ripening and induction of labour. Methods: A prospective randomised study was conducted on 150 patients with term singleton pregnancy admitted for induction of labour. Seventy-five patients were induced with both Foley bulb, and vaginal misoprostol and another 75 were given vaginal misoprostol alone for induction of labour. Both groups were then compared with respect to change in Bishop score, induction to the active phase of labour interval, induction delivery interval, duration of labour, maternal complications and neonatal outcomes. Data was analysed using statistical software SPSS version 11.5. Tests with P,.05 were considered significant. Results: The two groups were comparable with respect to maternal age, parity, gestational age, indication for induction, and initial Bishop scores. Both groups had a significant change in Bishop score (2.99 ± 1.72 and 2.17 ± 1.48 respectively with statistically significant difference (p=0.001 S, 95% C.I. -0.1978 to 0.8378). Mean induction to delivery interval was significantly lower in the combination group (11.76 ± 5.89 hours) than misoprostol group (14.54 ± 7.32 hours). Difference was of 2.78 hours (p=0.018,S, 95% CI -5.1042 to -0.4558). Induction to delivery interval was significantly lower in nulliparous women of combination group (13.64 ± 5.75 hours) than misoprostol group (18.4±7.09 hours), and the difference was of 4.76 hours (p=0.002, S, 95% CI 1.0465 to 14.7335). There was no difference between the groups in the mode of delivery, infant weight, Apgar score and intrapartum complications. Conclusion: From the present study it was concluded that addition of Foley catheter to vaginal misoprostol have the synergistic effect and results in early cervical ripening and delivery. These results suggest that the combination may be used to achieve timely and safe delivery in the presence of an unfavorable cervix. A combination of the Foley bulb and vaginal misoprostol resulted in a shorter induction-to-delivery time when compared with vaginal misoprostol alone without increasing labor complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bishop%20score" title="Bishop score">Bishop score</a>, <a href="https://publications.waset.org/abstracts/search?q=Foley%20catheter" title=" Foley catheter"> Foley catheter</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20of%20labor" title=" induction of labor"> induction of labor</a>, <a href="https://publications.waset.org/abstracts/search?q=misoprostol" title=" misoprostol"> misoprostol</a> </p> <a href="https://publications.waset.org/abstracts/68596/evaluation-of-non-pharmacological-method-transcervical-foley-catheter-and-misoprostol-to-intravaginal-misoprostol-for-preinduction-cervical-ripening" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68596.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">306</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">18721</span> Cepstrum Analysis of Human Walking Signal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koichi%20Kurita">Koichi Kurita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we propose a real-time data collection technique for the detection of human walking motion from the charge generated on the human body. This technique is based on the detection of a sub-picoampere electrostatic induction current, generated by the motion, flowing through the electrode of a wireless portable sensor attached to the subject. An FFT analysis of the wave-forms of the electrostatic induction currents generated by the walking motions showed that the currents generated under normal and restricted walking conditions were different. Moreover, we carried out a cepstrum analysis to detect any differences in the walking style. Results suggest that a slight difference in motion, either due to the individual’s gait or a splinted leg, is directly reflected in the electrostatic induction current generated by the walking motion. The proposed wireless portable sensor enables the detection of even subtle differences in walking motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20walking%20motion" title="human walking motion">human walking motion</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20measurement" title=" motion measurement"> motion measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20measurement" title=" current measurement"> current measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20induction" title=" electrostatic induction"> electrostatic induction</a> </p> <a href="https://publications.waset.org/abstracts/12335/cepstrum-analysis-of-human-walking-signal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12335.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">344</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">18720</span> An Improved Parameter Identification Method for Three Phase Induction Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liang%20Zhao">Liang Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chong-quan%20Zhong"> Chong-quan Zhong </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to improve the control performance of vector inverter, an improved parameter identification solution for induction motor is proposed in this paper. Dc or AC voltage is applied to the induction motor using the SVPWM through the inverter.

The discrete Fourier transform (DFT) is used to deal with the noise and harmonic. The impact on parameter identification caused by delays in the inverter switch tube, tube voltage drop and dead-time is avoided by effective compensation measures. Finally, the parameter identification experiment is conducted based on the vector inverter which using TMS320F2808 DSP as the core processor and results show that the strategy is verified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vector%20inverter" title="vector inverter">vector inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20identification" title=" parameter identification"> parameter identification</a>, <a href="https://publications.waset.org/abstracts/search?q=SVPWM%3B%20DFT" title=" SVPWM; DFT"> SVPWM; DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=dead-time%20compensation" title=" dead-time compensation"> dead-time compensation</a> </p> <a href="https://publications.waset.org/abstracts/58286/an-improved-parameter-identification-method-for-three-phase-induction-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58286.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">463</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">18719</span> Induction of Labor Using Misoprostol with or without Mifepristone in Intrauterine Death: A Randomized Controlled Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Agrawal">Ajay Agrawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pritha%20Basnet"> Pritha Basnet</a>, <a href="https://publications.waset.org/abstracts/search?q=Achala%20Thakur"> Achala Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Pappu%20Rizal"> Pappu Rizal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubina%20Rai"> Rubina Rai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: Rapid expulsion of fetus in intrauterine fetal death (IUFD) is usually requested without any medical grounds for it. So; an efficient, safe method for induction of labor (IOL) is required. Objective: To determine if pre-treatment with mifepristone followed by IOL with misoprostol in late IUFD is more efficacious. Methods: We conducted a randomized controlled trial in 100 patients. Group-A women received single oral dose of 200 mg mifepristone, followed by induction with vaginal misoprostol after 24-hour. Group-B women were induced only with vaginal misoprostol. In each group 5 dose of misoprostol was used 4 hourly. If first cycle was unsuccessful, after break of 12 hour, second course of misoprostol was started. The primary outcome was a measure of induction to delivery time and vaginal delivery within 24 hours. Secondary outcome was to measure need of oxytocin and complications. Results: Maternal age, parity and period of gestation were comparable between groups. Number of misoprostol dose needed in group A was significantly less than group B. Mann Whitney U test showed, women in group A had significantly earlier onset of labor, however total induction to delivery interval was not significant. In group-A, 85.7% delivered within 24 hours of first dose of misoprostol while in group-B 70% delivered within 24 hour (p=0.07). More women in Group B required oxytocin. Conclusion: Pretreatment with mifepristone before IOL following late IUFD is an effective and safe regimen. It appears to shorten the duration of induction to onset of labor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20of%20labor" title="induction of labor">induction of labor</a>, <a href="https://publications.waset.org/abstracts/search?q=intrauterine%20fetal%20death" title=" intrauterine fetal death"> intrauterine fetal death</a>, <a href="https://publications.waset.org/abstracts/search?q=mifepristone" title=" mifepristone"> mifepristone</a>, <a href="https://publications.waset.org/abstracts/search?q=misoprostol" title=" misoprostol"> misoprostol</a> </p> <a href="https://publications.waset.org/abstracts/19540/induction-of-labor-using-misoprostol-with-or-without-mifepristone-in-intrauterine-death-a-randomized-controlled-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19540.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">377</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">18718</span> Reliability Indices Evaluation of SEIG Rotor Core Magnetization with Minimum Capacitive Excitation for WECs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lokesh%20Varshney">Lokesh Varshney</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Saket"> R.

Twenty-four healthy ewes (n=24) on 138th gestation day were randomly separated according to induction methods (group I (n=6), (0.09% NaCl), group II (n=6) (dexamethasone, 16 mg im.), group III (n=6) (aglepristone 5mg/kg sc.) and group IV (n=6) (aglepristone, 2,5 mg/kg sc.+dexamethasone 8 mg im.). The blood samples of the ewes were collected at 12 hours intervals from induction time to the postpartum 2nd day in order to determine progesterone and estradiol 17-ß levels. These hormone concentrations were determined by ELISA, and obtained results were statistically analyzed with Kruskal Wallis and Dunn tests between the groups, and Friedman and Wilcoxon test within the groups. The results pointed out that there was no significant difference within the groups in terms of estradiol 17-ß (group 1, p=0.508; group 2, p=0.054; group 3, p=0.672; group 4, p=0,170). And there was only a significant difference at 138th day (p=0,019) between groups II and IV (p=0,010). There was a significant difference in terms of progesterone concentration within group 1, 2 and 4 (p=0.000). And there was a significant difference at all times except 138th day between the groups (p<0.05). As a conclusion, the induction of parturition methods could be performed successfully. These methods have no effect on estradiol 17-ß concentration but also make changings on progesterone concentrations as in groups 3 and 4. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ewe" title="ewe">ewe</a>, <a href="https://publications.waset.org/abstracts/search?q=estradiol%2017-%C3%9F" title=" estradiol 17-ß"> estradiol 17-ß</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20of%20parturition" title=" induction of parturition"> induction of parturition</a>, <a href="https://publications.waset.org/abstracts/search?q=progesterone" title=" progesterone"> progesterone</a> </p> <a href="https://publications.waset.org/abstracts/85271/evaluation-of-progesterone-and-estradiol17-ss-levels-in-ewes-induced-with-different-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85271.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">18714</span> Using of Particle Swarm Optimization for Loss Minimization of Vector-Controlled Induction Motors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Rashtchi">V.

Among the many loss minimization algorithms (LMAs) for an induction motor, a particle swarm optimization (PSO) has the advantages of fast response and high accuracy. However, the performance of the PSO and other optimization algorithms depend on the accuracy of the modeling of the motor drive and losses. In the development of the loss model, there is always a trade off between accuracy and complexity. This paper presents a new online optimization to determine an optimum flux level for the efficiency optimization of the vector-controlled induction motor drive. An induction motor (IM) model in d-q coordinates is referenced to the rotor magnetizing current. This transformation results in no leakage inductance on the rotor side, thus the decomposition into d-q components in the steady-state motor model can be utilized in deriving the motor loss model. The suggested algorithm is simple for implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20machine" title="induction machine">induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20minimization" title=" loss minimization"> loss minimization</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetizing%20current" title=" magnetizing current"> magnetizing current</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a> </p> <a href="https://publications.waset.org/abstracts/15437/using-of-particle-swarm-optimization-for-loss-minimization-of-vector-controlled-induction-motors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15437.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">633</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">18713</span> Determination of Suitability Between Single Phase Induction Motor and Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nakarin%20Prempri">Nakarin Prempri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Single-phase induction motors are widely used in industry. Most manufacturing processes use capacitor-run single-phase induction motors to drive mechanical loads. The selection of a suitable motor for driving is important. The optimum operating range of the motor can help the motor operate efficiently. Thus, this paper presents an operating range analysis of capacitor-run single-phase induction motors and a determination of suitability between motor and mechanical loads. an observational study found that the optimum operating range of the motor can be used to determine the suitability between the motor and the mechanical load.
