toxin-producing bacteria that can cause diarrhea and colitis. U.S. Center for Disease Control and Prevention revealed that C. difficile infection (CDI) has increased from 31 cases per 100,000 persons per year in 1996 to 61 per 100,000 in 2003. Approximately 500,000 cases per year occur in the United States. After exposure, the bacteria colonize the colon, where it adheres to the intestinal epithelium where it produces two toxins: TcdA and TcdB. TcdA affects the intestinal epithelium, causing fluid secretion, inflammation, and tissue necrosis, while TcdB acts as a cytotoxin purpose of this study was to evaluate the association between C diff infection and bronchial lung cancer development. Methods: Using ICD- 9 and ICD-10 codes, the data was provided by a Health Insurance Portability and Accountability Act (HIPAA) compliant national database to assess the patients infected with C diff as opposed to the non-infected patients. The Holy Cross Health, Fort Lauderdale, granted access to the database for the purpose of academic research. Patients were matched for age and Charlson Comorbidity Index (CCI). Standard statistical methods were used. Results: Bronchial lung cancer occurrence in the population not infected with C diff infection was 4741, as opposed to the population infected with C. diff, where 2039 cases of lung cancer were observed. The difference was statistically significant (p-value < 2.2x10^e-16), which reveals that C diff might be protective against bronchial lung cancer. The data was then matched by treatment to create to minimize the effect of treatment bias. Bronchial cancer incidence was 422 and 861 in infected vs. non-infected (p-value of < 2.2x10^e-16), which once more indicates that C diff infection could be beneficial in diminishing bronchial cancer development. Conclusion: This retrospective study conveys a statistical correlation between C diff infection and decreased incidence of lung bronchial cancer. Further studies are needed to comprehend the protective mechanisms of C. Diff infection on lung cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20diff" title="C. diff">C. diff</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title=" lung cancer"> lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=protective" title=" protective"> protective</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a> </p> <a href="https://publications.waset.org/abstracts/140195/the-correlation-between-clostridium-difficile-infection-and-bronchial-lung-cancer-occurrence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140195.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">235</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">2023</span> Association of Clostridium difficile Infection and Bone Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Prado">Daniela Prado</a>, <a href="https://publications.waset.org/abstracts/search?q=Lexi%20Frankel"> Lexi Frankel</a>, <a href="https://publications.waset.org/abstracts/search?q=Amalia%20Ardeljan"> Amalia Ardeljan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lokesh%20Manjani"> Lokesh Manjani</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Cardeiro"> Matthew Cardeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Rashid"> Omar Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Clostridium difficile (C. diff) is a gram-positive bacterium that is known to cause life-threatening diarrhea and severe inflammation of the colon. It originates as an alteration of the gut microbiome and can be transmitted through spores. Recent studies have shown a high association between the development of C. diff in cancer patients due to extensive hospitalization. However, research is lacking regarding C. diff’s association in the causation or prevention of cancer. The objective of this study was to therefore assess the correlation between Clostridium difficile infection (CDI) and the incidence of bone cancer. Methods: This retrospective analysis used data provided by a Health Insurance Portability and Accountability Act (HIPAA) compliant national database to evaluate the patients infected versus patients not infected with C. diff using ICD-10 and ICD-9 codes. Access to the database was granted by the Holy Cross Health, Fort Lauderdale, for the purpose of academic research. Standard statistical methods were used. Results: Between January 2010 and December 2019, the query was analyzed and resulted in 78863 patients in both the infected and control group, respectively. The two groups were matched by age range and CCI score. The incidence of bone cancer was 659 patients (0.835%) in the C. diff group compared to 1941 patients (2.461%) in the control group. The difference was statistically significant by a P-value < 2.2x10^-16 with an odds ratio (OR)= 0.33 (0.31-0.37) with a 95% confidence interval (CI). Treatment for CDI was analyzed for both C. diff infected and noninfected populations. 91 out of 16,676 (0.55%) patients with a prior C. diff infection and treated with antibiotics were compared to the control group were 275 out of 16,676 (1.65%) patients with no history of CDI and received antibiotic treatment. Results remained statistically significant by P-value <2.2x10-16 with an OR= 0.42 (0.37, 0.48). and a 95% CI. Conclusion: The study shows a statistically significant correlation between C. diff and a reduced incidence of bone cancer. Further evaluation is recommended to assess the potential of C. difficile in reducing bone cancer incidence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20cancer" title="bone cancer">bone cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=colitis" title=" colitis"> colitis</a>, <a href="https://publications.waset.org/abstracts/search?q=clostridium%20difficile" title=" clostridium difficile"> clostridium difficile</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiome" title=" microbiome"> microbiome</a> </p> <a href="https://publications.waset.org/abstracts/140192/association-of-clostridium-difficile-infection-and-bone-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140192.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">277</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">2022</span> Investigating the Flavin-Dependent Thymidylate Synthase (FDTS) Enzyme from Clostridioides Difficile (C. diff)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Shaw">Sidra Shaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarenna%20Shaw"> Sarenna Shaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae%20Joon%20Lee"> Chae Joon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Irimpan%20Mathews"> Irimpan Mathews</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Koehn"> Eric Koehn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the biggest public health concerns of our time is increasing antimicrobial resistance. As of 2019, the CDC has documented more than 2.8 million serious antibiotic resistant infections in the United States. Currently, antibiotic resistant infections are directly implicated in over 750,000 deaths per year globally. On our current trajectory, British economist Jim O’Neill predicts that by 2050, an additional 10 million people (about half the population of New York) will die annually due to drug resistant infections. As a result, new biochemical pathways must be targeted to generate next generation antibiotic drugs that will be effective against drug resistant bacteria. One enticing target is the biosynthesis of DNA within bacteria, as few drugs interrupt this essential life process. Thymidylate synthase enzymes are essential for life as they catalyze the synthesis of a DNA building block, 2′-deoxythymidine-5′-monophosphate (dTMP). In humans, the thymidylate synthase enzyme (TSase) has been shown to be distinct from the flavin-dependent thymidylate synthase (FDTS) produced by many pathogenic bacteria. TSase and FDTS have distinct structures and mechanisms of catalysis, which should allow selective inhibition of FDTS over human TSase. Currently, C. diff is one of the most antibiotic resistant bacteria, and no drugs that target thymine biosynthesis exist for C. diff. Here we present the initial biochemical characterization of FDTS from C. diff. Specifically, we examine enzyme kinetics and binding features of this enzyme to determine the nature of interaction with ligands/inhibitors and understand the molecular mechanism of catalysis. This research will provide more insight into the targetability of the C. diff FDTS enzyme for novel antibiotic drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flavin-dependent%20thymidylate%20synthase" title="flavin-dependent thymidylate synthase">flavin-dependent thymidylate synthase</a>, <a href="https://publications.waset.org/abstracts/search?q=FDTS" title=" FDTS"> FDTS</a>, <a href="https://publications.waset.org/abstracts/search?q=clostridioides%20difficile" title=" clostridioides difficile"> clostridioides difficile</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20diff" title=" C. diff"> C. diff</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title=" antibiotic resistance"> antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20synthesis" title=" DNA synthesis"> DNA synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20kinetics" title=" enzyme kinetics"> enzyme kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20features" title=" binding features"> binding features</a> </p> <a href="https://publications.waset.org/abstracts/165607/investigating-the-flavin-dependent-thymidylate-synthase-fdts-enzyme-from-clostridioides-difficile-c-diff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165607.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">104</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">2021</span> Soil and Environmental Management Awareness as Professional Competency of the Agricultural Extension Officers for Their Plans Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zafarullah%20Khan">Muhammad Zafarullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agricultural Extension Officers’ (AEOs) competency level in soil and environmental management awareness is important for interacting with farming communities of different types of soil. Questionnaire was developed for all AEOs for data collection to know the present position and needed position of competency on Likert scale from 01-05 by assigning very low (01) and very high (05). Wide gap was found in competency of suitability of various soil types for horticultural and agronomic crops and reclamation of saline soil. We observed that suitability ranking of various soil types for horticultural crops (Diff. = 1.21), agronomic crops (Diff. = 1.20) and soil borne diseases (Diff. = 1.19) were the top three important competencies where training or improvement is needed. To better fill this gap we recommend that professional qualification of AEOs should be enhanced and training opportunities should be provided to them particularly to deal with soil and environmental management awareness. Thus training opportunities may increase their competency and will add highly skilled manpower to the system for sustainable development to protect environment. It is therefore, recommended that AEOs may be provided pre and in service trainings of soil environmental management in order to equip them with a capacity to work with farming community effectively to boost the living standard of farming community and alleviate poverty for environmental protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=professional%20competency" title="professional competency">professional competency</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20extension%20officers" title=" agricultural extension officers"> agricultural extension officers</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20and%20environmental%20management%20awareness" title=" soil and environmental management awareness"> soil and environmental management awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=plans%20implementation" title=" plans implementation"> plans implementation</a> </p> <a href="https://publications.waset.org/abstracts/8961/soil-and-environmental-management-awareness-as-professional-competency-of-the-agricultural-extension-officers-for-their-plans-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8961.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">392</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">2020</span> Fuzzy Logic Based Sliding Mode Controller for a New Soft Switching Boost Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azam%20Salimi">Azam Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Delshad"> Majid Delshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a modified design of a sliding mode controller based on fuzzy logic for a New ZVThigh step up DC-DC Converter .

We propose a semi-parametric approach to estimate the mode of an unknown continuous multivariate density function. Our approach is based on a weighted average of a parametric density estimate using the Box-Cox transform and a non-parametric kernel density estimate. Our semi-parametric mode estimate improves both the parametric- and non-parametric- mode estimates. Specifically, our mode estimate solves the non-consistency problem of parametric mode estimates (at large sample sizes) and reduces the variability of non-parametric mode estimates (at small sample sizes). The performance of our method at practical sample sizes is demonstrated by simulation examples and two real examples from the fields of climatology and image recognition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Box-Cox%20transform" title="Box-Cox transform">Box-Cox transform</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20estimation" title=" density estimation"> density estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20seeking" title=" mode seeking"> mode seeking</a>, <a href="https://publications.waset.org/abstracts/search?q=semiparametric%20method" title=" semiparametric method"> semiparametric method</a> </p> <a href="https://publications.waset.org/abstracts/53756/a-semiparametric-approach-to-estimate-the-mode-of-continuous-multivariate-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53756.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">285</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">2016</span> Eye Diagram for a System of Highly Mode Coupled PMD/PDL Fiber </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suad%20M.%20Abuzariba">Suad M.

By using linear quantum hydrodynamic model, not only the quantum dispersion relation of rotation mode but also void structure has been derived in the presence of an external magnetic field. Although the phase velocity of the magnetized quantum breathing mode is greater than that of unmagnetized quantum breathing mode, attenuation of the magnetized quantum breathing mode along radial distance seems to be slower than that of unmagnetized quantum breathing mode. Clearly, drawing the quantum breathing mode in the presence and absence of a magnetic field, we found that the magnetic field alters the distribution of dust particles and changes the radial and azimuthal velocities around the axis. Because the magnetic field rotates the dust particles and collects them, it could compensate the void structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20linear%20quantum%20hydrodynamic%20model" title="the linear quantum hydrodynamic model">the linear quantum hydrodynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20magnetized%20quantum%20breathing%20mode" title=" the magnetized quantum breathing mode"> the magnetized quantum breathing mode</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20quantum%20dispersion%20relation%20of%20rotation%20mode" title=" the quantum dispersion relation of rotation mode"> the quantum dispersion relation of rotation mode</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20structure" title=" void structure"> void structure</a> </p> <a href="https://publications.waset.org/abstracts/69938/the-magnetized-quantum-breathing-in-cylindrical-dusty-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69938.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">298</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">2013</span> Working Mode and Key Technology of Thermal Vacuum Test Software for Spacecraft Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Lei">Zhang Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhan%20Haiyang"> Zhan Haiyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Gu%20Miao"> Gu Miao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A universal software platform is developed for improving the defects in the practical one.

The circuit’s interference rejection technique is based upon common-mode feed-forwarding where common-mode currents have cancelled each other at the output nodes. The common-mode current for cancellation is generated by means of common-mode sensing and emitter or source followers with resistors employing only one transistor. Simultaneously this particular transistor also provides common-mode feedback to the patient’s right/left leg to further reduce interference entering the amplifier. The proposed designs have been verified with simulations in 0.18-µm CMOS process operating under 1.0-V supply with CMRR greater than 80dB. Moreover ECG signals have experimentally recorded with the proposed instrumentation amplifiers implemented from discrete BJT (BC547, BC558) and MOSFET (ALD1106, ALD1107) transistors working with 1.5-V supply. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocardiogram" title="electrocardiogram">electrocardiogram</a>, <a href="https://publications.waset.org/abstracts/search?q=common-mode%20feedback" title=" common-mode feedback"> common-mode feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=common-mode%20feedforward" title=" common-mode feedforward"> common-mode feedforward</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20engineering" title=" communication engineering"> communication engineering</a> </p> <a href="https://publications.waset.org/abstracts/4913/compact-low-voltage-biomedical-instrumentation-amplifiers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4913.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">384</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">2011</span> Energy Saving Study of Mass Rapid Transit by Optimal Train Coasting Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artiya%20Sopharak">Artiya Sopharak</a>, <a href="https://publications.waset.org/abstracts/search?q=Tosaphol%20Ratniyomchai"> Tosaphol Ratniyomchai</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanatchai%20Kulworawanichpong"> Thanatchai Kulworawanichpong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an energy-saving study of Mass Rapid Transit (MRT) using an optimal train coasting operation. For the dynamic train movement with four modes of operation, including accelerating mode, constant speed or cruising mode, coasting mode, and braking mode are considered in this study. The acceleration rate, the deceleration rate, and the starting coasting point are taken into account the optimal train speed profile during coasting mode with considering the energy saving and acceptable travel time comparison to the based case with no coasting operation. In this study, the mathematical method as a Quadratic Search Method (QDS) is conducted to carry out the optimization problem. A single train of MRT services between two stations with a distance of 2 km and a maximum speed of 80 km/h is taken to be the case study. Regarding the coasting mode operation, the results show that the longer distance of costing mode, the less energy consumption in cruising mode and the less braking energy. On the other hand, the shorter distance of coasting mode, the more energy consumption in cruising mode and the more braking energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title="energy saving">energy saving</a>, <a href="https://publications.waset.org/abstracts/search?q=coasting%20mode" title=" coasting mode"> coasting mode</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20rapid%20transit" title=" mass rapid transit"> mass rapid transit</a>, <a href="https://publications.waset.org/abstracts/search?q=quadratic%20search%20method" title=" quadratic search method"> quadratic search method</a> </p> <a href="https://publications.waset.org/abstracts/122572/energy-saving-study-of-mass-rapid-transit-by-optimal-train-coasting-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122572.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">302</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">2010</span> Establishment of Bit Selective Mode Storage Covert Channel in VANETs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amarpreet%20Singh">Amarpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimi%20Manchanda"> Kimi Manchanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Intended for providing the security in the VANETS (Vehicular Ad hoc Network) scenario, the covert storage channel is implemented through data transmitted between the sender and the receiver.

To do so, a new low phase noise cross-coupled oscillator by using the general topology of cross-coupled oscillator and adding a differential stage for tail current shaping is designed. In addition, a tail current shaping technique to improve phase noise in differential LC VCOs is presented. The tail current becomes large when the oscillator output voltage arrives at the maximum or minimum value and when the sensitivity of the output phase to the noise is the smallest. Also, the tail current becomes small when the phase noise sensitivity is large. The proposed circuit does not use extra power and extra noisy active devices. Furthermore, this topology occupies small area. Simulation results show the improvement in phase noise by 2.5dB under the same conditions and at the carrier frequency of 1 GHz for GSM applications. The power consumption of the proposed circuit is 2.44 mW and the figure of merit (FOM) with -192.2 dBc/Hz is achieved for the new oscillator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LC%20oscillator" title="LC oscillator">LC oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20phase%20noise" title=" low phase noise"> low phase noise</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20shaping" title=" current shaping"> current shaping</a>, <a href="https://publications.waset.org/abstracts/search?q=diff%20mode" title=" diff mode"> diff mode</a> </p> <a href="https://publications.waset.org/abstracts/75354/a-low-phase-noise-cmos-lc-oscillator-with-tail-current-shaping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75354.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">600</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">2008</span> Inverse Mode Shape Problem of Hand-Arm Vibration (Humerus Bone) for Bio-Dynamic Response Using Varying Boundary Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20R">Ajay R</a>, <a href="https://publications.waset.org/abstracts/search?q=Rammohan%20B"> Rammohan B</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20K%20S%20S"> Sridhar K S S</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurusharan%20%20N"> Gurusharan N</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of the work is to develop a numerical method to solve the inverse mode shape problem by determining the cross-sectional area of a structure for the desired mode shape via the vibration response study of the humerus bone, which is in the form of a cantilever beam with anisotropic material properties.

Strategies for the use of traditional modes within the framework of sustainable urban transport are seen from three dimensions: social, economic and environmental. The social dimension related to accessibility and livability, an economic dimension related to traditional modes can promote products and tourist attractions, while the environmental dimension related to the needs of the users/groups with respect to safety, comfort. The traditional mode is rarely noticed by the policy makers, and public opinion in its use needs attention. The involvement of policy-making between stakeholders and the community is needed in the development of sustainable traditional mode strategies in support of urban tourism activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20mode" title="traditional mode">traditional mode</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation" title=" transportation"> transportation</a> </p> <a href="https://publications.waset.org/abstracts/73742/a-study-of-traditional-mode-in-the-framework-of-sustainable-urban-transportation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73742.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">265</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">2005</span> Impact of Instructional Mode and Medium of Instruction on the Learning Outcomes of Secondary Level School Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dipti%20Parida">Dipti Parida</a>, <a href="https://publications.waset.org/abstracts/search?q=Atasi%20Mohanty"> Atasi Mohanty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this research is to examine the interaction effect of flipped teaching and traditional teaching mode across two different medium (English and Odia) of instructional groups. Both Science and History subjects were taken to be taught in the Class- VIII in two different instructional mode/s. In total, 180 students of Class-VIII of both Odia and English medium schools were taken as the samples of this study; 90 participants (each group) were from both English and Odia medium schools ; 45 participants of each of these two groups were again assigned either to flip or traditional teaching method. We have two independent variables and each independent variable with two levels. Medium and mode of instruction are the two independent variables. Medium of instruction has two levels of Odia medium and English medium groups. The mode of instruction has also two levels of flip and traditional teaching method. Here we get 4 different groups, such as Odia medium students with traditional mode of teaching (O.M.T), Odia medium students with flipped mode of teaching (O.M.F), English medium students with traditional mode of teaching (E.M.T) and English medium students with flipped mode of teaching (E.M.F). Before the instructional administration, these four groups were given a test on the concerned topic to be taught. Based on this result, a one-way ANOVA was computed and the obtained result showed that these four groups don’t differ significantly from each other at the beginning. Then they were taught the concerned topic either in traditional or flip mode of teaching method. After that a 2×2×2 repeated measures ANOVA was done to analyze the group differences as well as the learning outcome before and after the teaching. The result table also shows that in post-test the learning outcome is highest in case of English medium students with flip mode of instruction. From the statistical analysis it is clear that the flipped mode of teaching is as effective for Odia medium students as it is for English medium students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medium%20of%20instruction" title="medium of instruction">medium of instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20of%20instruction" title=" mode of instruction"> mode of instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20mode" title=" test mode"> test mode</a>, <a href="https://publications.waset.org/abstracts/search?q=vernacular%20medium" title=" vernacular medium"> vernacular medium</a> </p> <a href="https://publications.waset.org/abstracts/71475/impact-of-instructional-mode-and-medium-of-instruction-on-the-learning-outcomes-of-secondary-level-school-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71475.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">355</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">2004</span> Interaction of the Circumferential Lamb Wave with Delamination in the Middle of Pipe Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Ziming">Li Ziming</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20Cunfu"> He Cunfu</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Zenghua"> Liu Zenghua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With aim for delamination type defects detection in manufacturing process of seamless pipe,this paper studies the interaction of the circumferential lamb wave with delamination in aluminum pipe.The delamination is located in the middle of pipe wall.A numerical study is carried out,the circumferential lamb wave used here is CL0 mode,which is generated with a finite element method code.Wave structures from the simulation are compared with theoretical results to verify the model’s accuracy.Delamination along the circumferential direction is established by demerging nodes of the same coordinates.When CL0 mode is incident at the entrance and exit of a delamination,it generates new mode-CL1,undergoes multiple reverberation and mode conversions between the two ends of the delamination.

Some results are reported concerned with refractive index profile optimization for 42 µm core 16-LP-mode optical fiber for next-generation optical networks. Here special refractive index profile form provides total DMD reducing over all mode staff under desired enhanced mode effective area. Method for the simulation of 'real manufactured' few-mode optical fiber (FMF) core geometry differing from the desired optimized structure by core non-symmetrical ellipticity and refractive index profile deviation including local fluctuations is proposed. Results of the following analysis of optimized FMF with inserted geometry distortions performed by earlier on developed modification of rigorous mixed finite-element method showed strong DMD degradation that requires additional higher-order mode management. In addition, this work also presents a method for design mode division multiplexer channel precision spatial positioning scheme at FMF core end that provides one of the potentiality solutions of described DMD degradation problem concerned with 'distorted' core geometry due to features of optical fiber manufacturing techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20mode%20delay" title="differential mode delay">differential mode delay</a>, <a href="https://publications.waset.org/abstracts/search?q=few-mode%20optical%20fibers" title=" few-mode optical fibers"> few-mode optical fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20Shannon%20limit" title=" nonlinear Shannon limit"> nonlinear Shannon limit</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20fiber%20non-circularity" title=" optical fiber non-circularity"> optical fiber non-circularity</a>, <a href="https://publications.waset.org/abstracts/search?q=%E2%80%98real%20manufactured%E2%80%99%20optical%20fiber%20core%20geometry%20simulation" title=" ‘real manufactured’ optical fiber core geometry simulation"> ‘real manufactured’ optical fiber core geometry simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=refractive%20index%20profile%20optimization" title=" refractive index profile optimization"> refractive index profile optimization</a> </p> <a href="https://publications.waset.org/abstracts/99073/large-core-silica-few-mode-optical-fibers-with-reduced-differential-mode-delay-and-enhanced-mode-effective-area-over-c-band" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99073.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">157</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">1998</span> Theory of Gyrotron Amplifier in a Vane-Loaded Waveguide with Inner Dielectric Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reyhaneh%20Hashemi">Reyhaneh Hashemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrooz%20Saviz"> Shahrooz Saviz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In his study, we have survey the theory of gyrotron amplifier in a vane-loaded waveguide with inner dielectric material.

From numerical analysis of this dispersion relation, it is shown that the stability behavior of the fast-wave mode is dependent of the dielectric constant. With a small axial momentum spreed, a super bandwidth is shown to be attainable by a mixed mode operation. Also, with the utilization from the numeric analysis of relation dispersion.

Such problem can be overcome using a higher-order sliding mode controller (HOSMC) which preserves the main properties of the standard sliding mode and deliberately increases the control smoothness. In this paper, we propose a new HOSMC for a class of uncertain multi-input multi-output nonlinear systems. Based on high gain and integral sliding mode paradigms, the established control scheme removes theoretically the chattering phenomenon and provides the stability of the control system. Numerical simulations are developed to show the effectiveness of the proposed controller when applied to solve a control problem of two water levels into a quadruple-tank process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20systems" title="nonlinear systems">nonlinear systems</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title=" sliding mode control"> sliding mode control</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20gain" title=" high gain"> high gain</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20order" title=" higher order"> higher order</a> </p> <a href="https://publications.waset.org/abstracts/84589/a-combined-high-gain-higher-order-sliding-mode-controller-for-a-class-of-uncertain-nonlinear-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84589.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">327</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">1996</span> Modelling Mode Choice Behaviour Using Cloud Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leah%20Wright">Leah Wright</a>, <a href="https://publications.waset.org/abstracts/search?q=Trevor%20Townsend"> Trevor Townsend</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mode choice models are crucial instruments in the analysis of travel behaviour. These models show the relationship between an individual’s choice of transportation mode for a given O-D pair and the individual’s socioeconomic characteristics such as household size and income level, age and/or gender, and the features of the transportation system. The most popular functional forms of these models are based on Utility-Based Choice Theory, which addresses the uncertainty in the decision-making process with the use of an error term. However, with the development of artificial intelligence, many researchers have started to take a different approach to travel demand modelling. In recent times, researchers have looked at using neural networks, fuzzy logic and rough set theory to develop improved mode choice formulas. The concept of cloud theory has recently been introduced to model decision-making under uncertainty. Unlike the previously mentioned theories, cloud theory recognises a relationship between randomness and fuzziness, two of the most common types of uncertainty. This research aims to investigate the use of cloud theory in mode choice models. This paper highlights the conceptual framework of the mode choice model using cloud theory. Merging decision-making under uncertainty and mode choice models is state of the art. The cloud theory model is expected to address the issues and concerns with the nested logit and improve the design of mode choice models and their use in travel demand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cloud%20theory" title="Cloud theory">Cloud theory</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making" title=" decision-making"> decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20choice%20models" title=" mode choice models"> mode choice models</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20behaviour" title=" travel behaviour"> travel behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/56507/modelling-mode-choice-behaviour-using-cloud-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1995</span> A Novel Fuzzy Second-Order Sliding Mode Control of a Doubly Fed Induction Generator for Wind Energy Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elhadj%20Bounadja">Elhadj Bounadja</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Oulhadj%20Mahmoudi"> Mohand Oulhadj Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Djahbar"> Abdelkader Djahbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinelaabidine%20Boudjema"> Zinelaabidine Boudjema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we present a novel fuzzy second-order sliding mode control (FSOSMC) for wind energy conversion system based on a doubly-fed induction generator (DFIG). The proposed control strategy combines a fuzzy logic and a second-order sliding mode for the DFIG control. This strategy presents attractive features such as chattering-free, compared to the conventional first and second order sliding mode techniques. The use of this method provides very satisfactory performance for the DFIG control. The overall strategy has been validated on a 1.5-MW wind turbine driven a DFIG using the Matlab/Simulink. <p class="card-text"><strong>Keywords:</strong> <a
