Three different metabolic scenarios (‘healthy’, ‘inflamed’ and ‘medicated’) were modeled over a gene expression data-driven constructed tissue-specific metabolic reconstruction of mature astrocytes. Astrocyte reconstruction was built, validated and constrained using three open source software packages (‘minval’, ‘g2f’ and ‘exp2flux’) released through the Comprehensive R Archive Network repositories during the development of this work. From our analysis, we predict that tibolone executes their neuroprotective effects through a reduction of neurotoxicity mediated by L-glutamate in astrocytes, inducing the activation several metabolic pathways with neuroprotective actions associated such as taurine metabolism, gluconeogenesis, calcium and the Peroxisome Proliferator Activated Receptor signaling pathways. Also, we found a tibolone associated increase in growth rate probably in concordance with previously reported side effects of steroid compounds in other human cell types. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astrocytes" title="astrocytes">astrocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20balance%20analysis" title=" flux balance analysis"> flux balance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20scale%20metabolic%20reconstruction" title=" genome scale metabolic reconstruction"> genome scale metabolic reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotection" title=" neuroprotection"> neuroprotection</a>, <a href="https://publications.waset.org/abstracts/search?q=tibolone" title=" tibolone"> tibolone</a> </p> <a href="https://publications.waset.org/abstracts/94348/identifying-metabolic-pathways-associated-with-neuroprotection-mediated-by-tibolone-in-human-astrocytes-under-an-induced-inflammatory-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94348.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">223</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">29313</span> The Trend of Competitive Balance in Turkish Football Super League</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tugbay%20Inan">Tugbay Inan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Competitive balance is known to have an important effect in determining the result of football matches. The degree of competitiveness is referred as competitive balance in football. Sports economics are the extent to which overall league attendances will be raised by measures, such as media effect, home advantage, revenue sharing, which aim to improve competitive balance. The purpose of present study was to measure the competitive balance in the football league of Turkey. In this study, by using long term competitive balance analysis, some facing problems and precautions were discussed through the seasons (1987-2014) in Turkish Football Super League (TSL). Within the practice of this study, The way that competitive balance level followed was determined in the history of super league (27 years). Based on this purpose, C5 Competitive Balance Index (C5CBI) and a Herfindahl index of competitive balance (HICB) were used. Finally, it is seen that in Super League, competitive balance factor took place time to time, however in total, a view apart from competitive balance is obviously seen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competitive%20balance" title="competitive balance">competitive balance</a>, <a href="https://publications.waset.org/abstracts/search?q=turkish%20football" title=" turkish football"> turkish football</a>, <a href="https://publications.waset.org/abstracts/search?q=c5%20competitive%20balance%20index" title=" c5 competitive balance index"> c5 competitive balance index</a>, <a href="https://publications.waset.org/abstracts/search?q=Herfindahl-Hirschman%20Index" title=" Herfindahl-Hirschman Index"> Herfindahl-Hirschman Index</a> </p> <a href="https://publications.waset.org/abstracts/27980/the-trend-of-competitive-balance-in-turkish-football-super-league" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27980.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">559</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">29312</span> A Comprehensive Review of Axial Flux Machines and Its Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahbaz%20Amin">Shahbaz Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabir%20Hussain%20Shah"> Sabir Hussain Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahib%20Khan"> Sahib Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a thorough review concerning the design types of axial flux permanent magnet machines (AFPM) in terms of different features such as construction, design, materials, and manufacturing.

Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new dry tube (DT) has been installed in the tank of KAMINI research reactor, Kalpakkam India. This tube will be used for neutron activation analysis of small to large samples and testing of neutron detectors. DT tube is 375 cm height and 7.5 cm in diameter, located 35 cm away from the core centre. The experimental thermal flux at various axial positions inside the tube has been measured by irradiating the flux monitor (¹⁹⁷Au) at 20kW reactor power. The measured activity of ¹⁹⁸Au and the thermal cross section of ¹⁹⁷Au (n,γ) ¹⁹⁸Au reaction were used for experimental thermal flux measurement. The flux inside the tube varies from 10⁹ to 10¹⁰ and maximum flux was (1.02 ± 0.023) x10¹⁰ n cm⁻²s⁻¹ at 36 cm from the bottom of the tube. The Au and Zr foils without and with cadmium cover of 1-mm thickness were irradiated at the maximum flux position in the DT to find out the irradiation specific input parameters like sub-cadmium to epithermal neutron flux ratio (f) and the epithermal neutron flux shape factor (α). The f value was 143 ± 5, indicates about 99.3% thermal neutron component and α value was -0.2886 ± 0.0125, indicates hard epithermal neutron spectrum due to insufficient moderation. The measured flux profile has been validated using theoretical model of KAMINI reactor through Monte Carlo N-Particle Code (MCNP). In MCNP, the complex geometry of the entire reactor is modelled in 3D, ensuring minimum approximations for all the components. Continuous energy cross-section data from ENDF-B/VII.1 as well as S (α, β) thermal neutron scattering functions are considered. The neutron flux has been estimated at the corresponding axial locations of the DT using mesh tally. The thermal flux obtained from the experiment shows good agreement with the theoretically predicted values by MCNP, it was within ± 10%. It can be concluded that this MCNP model can be utilized for calculating other important parameters like neutron spectra, dose rate, etc. and multi elemental analysis can be carried out by irradiating the sample at maximum flux position using measured f and α parameters by k₀-NAA standardization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neutron%20flux" title="neutron flux">neutron flux</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20activation%20analysis" title=" neutron activation analysis"> neutron activation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20flux%20shape%20factor" title=" neutron flux shape factor"> neutron flux shape factor</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNP" title=" MCNP"> MCNP</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20N-Particle%20Code" title=" Monte Carlo N-Particle Code"> Monte Carlo N-Particle Code</a> </p> <a href="https://publications.waset.org/abstracts/99662/measurement-and-simulation-of-axial-neutron-flux-distribution-in-dry-tube-of-kamini-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99662.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">163</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">29309</span> Analysis of Flux-Linkage Performance of DFIG by Using Simulink under Different Types of Faults and Locations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Moustafa%20Mahmoud%20Sedky">Mohamed Moustafa Mahmoud Sedky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The double-fed induction generator wind turbine has recently received a great attention.

Cyanobacteria store carbon in the form of glycogen which can be hydrolyzed to release glucose and fermented to form bioethanol or other valuable products. Marine cyanobacterial species are especially attractive for countries with scarcity of freshwater. We recently identified a marine native cyanobacterium Synechococcus sp. BDU 130192 which has good growth rate and high level of polyglucans accumulation compared to Synechococcus PCC 7002. In this study, firstly we sequenced the whole genome and the sequences were annotated using the RAST server. Genome scale metabolic model (GSMM) was reconstructed through COBRA toolbox. GSMM is a computational representation of the metabolic reactions and metabolites of the target strain. GSMMs construction through the application of Flux Balance Analysis (FBA), which uses external nutrient uptake rates and estimate steady state intracellular and extracellular reaction fluxes, including maximization of cell growth. The model, which we have named isyn942, includes 942 reactions and 913 metabolites having 831 metabolic, 78 transport and 33 exchange reactions. The phylogenetic tree obtained by BLAST search revealed that the strain was a close relative of Synechococcus PCC 7002. The flux balance analysis (FBA) was applied on the model iSyn942 to predict the theoretical yields (mol product produced/mol CO₂ consumed) for native and non-native products like acetone, butanol, etc. under phototrophic condition by applying metabolic engineering strategies. The reported strain can be a viable strain for biotechnological applications, and the model will be helpful to researchers interested in understanding the metabolism as well as to design metabolic engineering strategies for enhanced production of various bioproducts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyanobacteria" title="cyanobacteria">cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20balance%20analysis" title=" flux balance analysis"> flux balance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20scale%20metabolic%20model" title=" genome scale metabolic model"> genome scale metabolic model</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20engineering" title=" metabolic engineering"> metabolic engineering</a> </p> <a href="https://publications.waset.org/abstracts/102140/evaluating-the-potential-of-a-fast-growing-indian-marine-cyanobacterium-by-reconstructing-and-analysis-of-a-genome-scale-metabolic-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102140.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">158</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">29306</span> The Influence of Different Flux Patterns on Magnetic Losses in Electric Machine Cores</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natheer%20Alatawneh">Natheer Alatawneh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The finite element analysis of magnetic fields in electromagnetic devices shows that the machine cores experience different flux patterns including alternating and rotating fields. The rotating fields are generated in different configurations range between circular and elliptical with different ratios between the major and minor axis of the flux locus. Experimental measurements on electrical steel exposed to different flux patterns disclose different magnetic losses in the samples under test. Consequently, electric machines require special attention during the cores loss calculation process to consider the flux patterns. In this study, a circular rotational single sheet tester is employed to measure the core losses in electric steel sample of M36G29. The sample was exposed to alternating field, circular field, and elliptical fields with axis ratios of 0.2, 0.4, 0.6 and 0.8. The measured data was implemented on 6-4 switched reluctance motor at three different frequencies of interest to the industry as 60 Hz, 400 Hz, and 1 kHz. The results disclose a high margin of error that may occur during the loss calculations if the flux patterns issue is neglected. The error in different parts of the machine associated with considering the flux patterns can be around 50%, 10%, and 2% at 60Hz, 400Hz, and 1 kHz, respectively. The future work will focus on the optimization of machine geometrical shape which has a primary effect on the flux pattern in order to minimize the magnetic losses in machine cores. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternating%20core%20losses" title="alternating core losses">alternating core losses</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20machines" title=" electric machines"> electric machines</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rotational%20core%20losses" title=" rotational core losses"> rotational core losses</a> </p> <a href="https://publications.waset.org/abstracts/64360/the-influence-of-different-flux-patterns-on-magnetic-losses-in-electric-machine-cores" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64360.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">252</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">29305</span> Assessment of Land Use Land Cover Change-Induced Climatic Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20K.%20Jat">Mahesh K.

Changes in the biophysical properties of the Earth's surface and its impact on climate are of primary concern nowadays. Different approaches, ranging from location-based relationships or modelling earth surface - atmospheric interaction through modelling techniques like surface energy balance (SEB) are used in the recent past to examine the relationship between changes in Earth surface land cover and climatic characteristics like temperature and precipitation. A remote sensing-based model i.e., Surface Energy Balance Algorithm for Land (SEBAL), has been used to estimate the surface heat fluxes over Mahi Bajaj Sagar catchment (India) from 2001 to 2020. Landsat ETM and OLI satellite data are used to model the SEB of the area. Changes in observed precipitation and temperature, obtained from India Meteorological Department (IMD) have been correlated with changes in surface heat fluxes to understand the relative contributions of LULC change in changing these climatic variables. Results indicate a noticeable impact of LULC changes on climatic variables, which are aligned with respective changes in SEB components. Results suggest that precipitation increases at a rate of 20 mm/year. The maximum and minimum temperature decreases and increases at 0.007 ℃ /year and 0.02 ℃ /year, respectively. The average temperature increases at 0.009 ℃ /year. Changes in latent heat flux and sensible heat flux positively correlate with precipitation and temperature, respectively. Variation in surface heat fluxes influences the climate parameters and is an adequate reason for climate change. So, SEB modelling is helpful to understand the LULC change and its impact on climate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LULC" title="LULC">LULC</a>, <a href="https://publications.waset.org/abstracts/search?q=sensible%20heat%20flux" title=" sensible heat flux"> sensible heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20heat%20flux" title=" latent heat flux"> latent heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=SEBAL" title=" SEBAL"> SEBAL</a>, <a href="https://publications.waset.org/abstracts/search?q=landsat" title=" landsat"> landsat</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation" title=" precipitation"> precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/148365/assessment-of-land-use-land-cover-change-induced-climatic-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148365.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">116</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">29304</span> Relationship between Body Composition and Balance in Young Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferruh%20Taspinar">Ferruh Taspinar</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulce%20K.%20Seyyar"> Gulce K.

The aim of this study was to investigate the relationship between body composition and balance. One hundred and thirty two young adults (58 male, 74 female) were included in the study. Mean age of participants were found as 21.21±1.51 years. Body composition (body mass index, total body fat ratio, total body muscle ratio) and balance (right anterior, right postero-medial, right postero-lateral, left anterior, left postero-medial, left postero-lateral) were evaluated by Tanita BC-418 and Y balance test, respectively. Pearson correlation analysis was used to evaluate the correlation between the parameters. Significance level in statistical analysis was accepted as 0.05. According to results, no correlation was found between body mass index and balance parameters. There was negative correlation between total body fat ratio and balance parameters (r=0.419-0.509, p˂0.05). On the other hand, positive correlation was found between total body muscle ratio and balance parameters (r=0.390-0.494, p˂0.05). This study demonstrated that body fat and muscle ratio affects the balance. Body composition should be considered in rehabilitation programs including postural balance training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20composition" title=" body composition"> body composition</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20mass" title=" body mass"> body mass</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adults" title=" young adults"> young adults</a> </p> <a href="https://publications.waset.org/abstracts/60501/relationship-between-body-composition-and-balance-in-young-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60501.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">374</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">29303</span> Optimizing Cell Culture Performance in an Ambr15 Microbioreactor Using Dynamic Flux Balance and Computational Fluid Dynamic Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=William%20Kelly">William Kelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Sorelle%20Veigne"> Sorelle Veigne</a>, <a href="https://publications.waset.org/abstracts/search?q=Xianhua%20Li"> Xianhua Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuyi%20Huang"> Zuyi Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyamsundar%20Subramanian"> Shyamsundar Subramanian</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Schaefer"> Eugene Schaefer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ambr15™ bioreactor is a single-use microbioreactor for cell line development and process optimization. The ambr system offers fully automatic liquid handling with the possibility of fed-batch operation and automatic control of pH and oxygen delivery. With operating conditions for large scale biopharmaceutical production properly scaled down, micro bioreactors such as the ambr15™ can potentially be used to predict the effect of process changes such as modified media or different cell lines. In this study, gassing rates and dilution rates were varied for a semi-continuous cell culture system in the ambr15™ bioreactor. The corresponding changes to metabolite production and consumption, as well as cell growth rate and therapeutic protein production were measured. Conditions were identified in the ambr15™ bioreactor that produced metabolic shifts and specific metabolic and protein production rates also seen in the corresponding larger (5 liter) scale perfusion process. A Dynamic Flux Balance model was employed to understand and predict the metabolic changes observed. The DFB model-predicted trends observed experimentally, including lower specific glucose consumption when CO₂ was maintained at higher levels (i.e. 100 mm Hg) in the broth. A Computational Fluid Dynamic (CFD) model of the ambr15™ was also developed, to understand transfer of O₂ and CO₂ to the liquid. This CFD model predicted gas-liquid flow in the bioreactor using the ANSYS software. The two-phase flow equations were solved via an Eulerian method, with population balance equations tracking the size of the gas bubbles resulting from breakage and coalescence. Reasonable results were obtained in that the Carbon Dioxide mass transfer coefficient (kLa) and the air hold up increased with higher gas flow rate. Volume-averaged kLa values at 500 RPM increased as the gas flow rate was doubled and matched experimentally determined values. These results form a solid basis for optimizing the ambr15™, using both CFD and FBA modelling approaches together, for use in microscale simulations of larger scale cell culture processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title="cell culture">cell culture</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20flux%20balance%20analysis" title=" dynamic flux balance analysis"> dynamic flux balance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microbioreactor" title=" microbioreactor"> microbioreactor</a> </p> <a href="https://publications.waset.org/abstracts/52076/optimizing-cell-culture-performance-in-an-ambr15-microbioreactor-using-dynamic-flux-balance-and-computational-fluid-dynamic-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52076.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">29302</span> Optimization of a Flux Switching Permanent Magnet Machine Using Laminated Segmented Rotor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedmilad%20Kazemisangdehi">Seyedmilad Kazemisangdehi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedmehdi%20Kazemisangdehi"> Seyedmehdi Kazemisangdehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flux switching permanent magnet machines are considered for wide range of applications because of their outstanding merits including high torque/power densities, high efficiency, simple and robust rotor structure. Therefore, several topologies have been proposed like the PM exited flux switching machine, hybrid excited flux switching type, and so on. Recently, a novel laminated segmented rotor flux switching permanent magnet machine was introduced. It features flux barriers on rotor structure to enhance the performances of machine including torque ripple reduction and also torque and efficiency improvements at the same time. This is while, the design of barriers was not optimized by the authors. Therefore, in this paper three coefficients regarding the position of the barriers are considered for optimization. The effect of each coefficient on the performance of this machine is investigated by finite element method and finally an optimized design of flux barriers based on these three coefficients is proposed from different points of view including electromagnetic torque maximization and cogging torque/torque ripple minimization. At optimum design from maximum developed torque aspect, this machine generates 0.65 Nm torque higher than that of the not-optimized design with an almost 0.4 % improvement in efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=FSPM" title=" FSPM"> FSPM</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20segmented%20rotor%20flux%20switching%20permanent%20magnet%20machine" title=" laminated segmented rotor flux switching permanent magnet machine"> laminated segmented rotor flux switching permanent magnet machine</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/127513/optimization-of-a-flux-switching-permanent-magnet-machine-using-laminated-segmented-rotor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127513.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">229</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">29301</span> Flux-Linkage Performance of DFIG Under Different Types of Faults and Locations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Moustafa%20Mahmoud%20Sedky">Mohamed Moustafa Mahmoud Sedky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The double-fed induction generator wind turbine has recently received a great attention.

Winding deformation is one of the main transformer defects, and timely and effective detection of the transformer winding deformation can ensure the safe and stable operation of the transformer to the maximum extent. When winding deformation occurs, the size, shape and spatial position of the winding will change, which directly leads to the change of magnetic flux leakage distribution. Therefore, it is promising to study the online detection method of the transformer winding deformation based on magnetic flux leakage characteristics, in which the key step is to study the optimal placement method of magnetic flux leakage sensors inside the transformer. In this paper, a simulation model of the transformer winding deformation is established to obtain the internal magnetic flux leakage distribution of the transformer under normal operation and different winding deformation conditions, and the law of change of magnetic flux leakage distribution due to winding deformation is analyzed. The results show that different winding deformation leads to different characteristics of the magnetic flux leakage distribution. On this basis, an optimized placement of magnetic flux leakage sensors inside the transformer is proposed to provide a basis for the online detection method of transformer winding deformation based on the magnetic flux leakage characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20flux%20leakage" title="magnetic flux leakage">magnetic flux leakage</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20placement%20method" title=" sensor placement method"> sensor placement method</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=winding%20deformation" title=" winding deformation"> winding deformation</a> </p> <a href="https://publications.waset.org/abstracts/136348/research-on-placement-method-of-the-magnetic-flux-leakage-sensor-based-on-online-detection-of-the-transformer-winding-deformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136348.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">196</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">29299</span> Finite Element Analysis of High Performance Synchronous Reluctance Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Mohanarajah">T.

Marine sediments act as a preliminary indicator of heavy metal contamination in the coastal and estuarine environment, which has adverse effects on biota as well as in the marine system. The aim of the current study was to evaluate the contamination status, enrichment, and flux of heavy metals in two monitoring years from coastal sediments of Pakistan. A total of 74 sediment samples were collected from seven coastal areas of Pakistan in two monitoring years, 2001-03 (MY-I) and 2011-13 (MY-II). The geochemical properties (grain size analysis, organic contents and eight heavy metals, i.e. Fe, Zn, Cu, Cr, Ni, Co, Pb, and Cd) of all sediment samples were analyzed. A significant increase in Fe, Ni and Cr concentrations detected between the years, whereas no significant differences were exhibited in Cu, Zn, Co, Pb and Cd concentrations. The extremely high enrichment (>50) of Cu, Zn, Pb and Cd were scrutinized in both monitoring years. The annual deposition flux of heavy metals ranged from 0.63 to 66.44 and 0.78 to 68.27 tons per year in MY-I and MY-II, respectively, with the lowest flux evaluated for Cd and highest for Zn in both monitoring years. A significant increase (p <0.05) was observed in the burial flux of Cr and Ni during the last decade in coastal sediments. The use of geo-indicators is helpful to assess the contamination analysis for management and conservation of the marine environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20contamination" title="coastal contamination">coastal contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=enrichment%20factor" title=" enrichment factor"> enrichment factor</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-indicator" title=" geo-indicator"> geo-indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20flux" title=" heavy metal flux"> heavy metal flux</a> </p> <a href="https://publications.waset.org/abstracts/69834/enrichment-and-flux-of-heavy-metals-along-the-coastal-sediments-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69834.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">379</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">29297</span> Magnetic End Leakage Flux in a Spoke Type Rotor Permanent Magnet Synchronous Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petter%20Eklund">Petter Eklund</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Sj%C3%B6lund"> Jonathan Sjölund</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Eriksson"> Sandra Eriksson</a>, <a href="https://publications.waset.org/abstracts/search?q=Mats%20Leijon"> Mats Leijon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The spoke type rotor can be used to obtain magnetic flux concentration in permanent magnet machines. This allows the air gap magnetic flux density to exceed the remanent flux density of the permanent magnets but gives problems with leakage fluxes in the magnetic circuit. The end leakage flux of one spoke type permanent magnet rotor design is studied through measurements and finite element simulations. The measurements are performed in the end regions of a 12 kW prototype generator for a vertical axis wind turbine. The simulations are made using three dimensional finite elements to calculate the magnetic field distribution in the end regions of the machine. Also two dimensional finite element simulations are performed and the impact of the two dimensional approximation is studied. It is found that the magnetic leakage flux in the end regions of the machine is equal to about 20% of the flux in the permanent magnets. The overestimation of the performance by the two dimensional approximation is quantified and a curve-fitted expression for its behavior is suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=end%20effects" title="end effects">end effects</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20leakage%20flux" title=" end leakage flux"> end leakage flux</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20machine" title=" permanent magnet machine"> permanent magnet machine</a>, <a href="https://publications.waset.org/abstracts/search?q=spoke%20type%20rotor" title=" spoke type rotor"> spoke type rotor</a> </p> <a href="https://publications.waset.org/abstracts/65632/magnetic-end-leakage-flux-in-a-spoke-type-rotor-permanent-magnet-synchronous-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65632.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">332</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">29296</span> Developing the Methods for the Study of Static and Dynamic Balance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Abuzayan">K.

Many factors have been identified as influencing static balance control. Therefore, the aim of this study was to apply the (XCoM) method and other relevant variables (CoP, CoM, Fh, KE, P, Q, and, AI) to investigate sport related activities such as hopping and jumping. Many studies have represented the CoP data without mentioning its accuracy, so several experiments were done to establish the agreement between the CoP and the projected CoM in a static condition. Five male healthy (Mean ± SD:- age 24.6 years ±4.5, height 177 cm ± 6.3, body mass 72.8 kg ± 6.6) participated in this study. Results found that The implementation of the XCoM method was found to be practical for evaluating both static and dynamic balance. The general findings were that the CoP, the CoM, the XCoM, Fh, and Q were more informative than the other variables (e.g. KE, P, and AI) during static and dynamic balance. The XCoM method was found to be applicable to dynamic balance as well as static balance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centre%20of%20mass" title="centre of mass">centre of mass</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20balance" title=" static balance"> static balance</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20balance" title=" dynamic balance"> dynamic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=extrapolated%20centre%20of%20mass" title=" extrapolated centre of mass"> extrapolated centre of mass</a> </p> <a href="https://publications.waset.org/abstracts/3232/developing-the-methods-for-the-study-of-static-and-dynamic-balance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3232.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">420</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">29295</span> Estimation of Fourier Coefficients of Flux Density for Surface Mounted Permanent Magnet (SMPM) Generators by Direct Search Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramakrishna%20Rao%20Mamidi">Ramakrishna Rao Mamidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is essential for Surface Mounted Permanent Magnet (SMPM) generators to determine the performance prediction and analyze the magnet’s air gap flux density wave shape. The flux density wave shape is neither a pure sine wave or square wave nor a combination. This is due to the variation of air gap reluctance between the stator and permanent magnets. The stator slot openings and the number of slots make the wave shape highly complicated. To reduce the complexity of analysis, approximations are made to the wave shape using Fourier analysis. In contrast to the traditional integration method, the Fourier coefficients, an and bn, are obtained by direct search method optimization. The wave shape with optimized coefficients gives a wave shape close to the desired wave shape. Harmonics amplitudes are worked out and compared with initial values. It can be concluded that the direct search method can be used for estimating Fourier coefficients for irregular wave shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20search" title="direct search">direct search</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20plot" title=" flux plot"> flux plot</a>, <a href="https://publications.waset.org/abstracts/search?q=fourier%20analysis" title=" fourier analysis"> fourier analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnets" title=" permanent magnets"> permanent magnets</a> </p> <a href="https://publications.waset.org/abstracts/139812/estimation-of-fourier-coefficients-of-flux-density-for-surface-mounted-permanent-magnet-smpm-generators-by-direct-search-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139812.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">29294</span> Investigation of Permeate Flux through DCMD Module by Inserting S-Ribs Carbon-Fiber Promoters with Ascending and Descending Hydraulic Diameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chii-Dong%20Ho">Chii-Dong Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian-Har%20Chen"> Jian-Har Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The decline in permeate flux across membrane modules is attributed to the increase in temperature polarization resistance in flat-plate Direct Contact Membrane Distillation (DCMD) modules for pure water productivity. Researchers have discovered that this effect can be diminished by embedding turbulence promoters, which augment turbulence intensity at the cost of increased power consumption, thereby improving vapor permeate flux. The device performance of DCMD modules for permeate flux was further enhanced by shrinking the hydraulic diameters of inserted S-ribs carbon-fiber promoters as well as considering the energy consumption increment. The mass-balance formulation, based on the resistance-in-series model by energy conservation in one-dimensional governing equations, was developed theoretically and conducted experimentally on a flat-plate polytetrafluoroethylene/polypropylene (PTFE/PP) membrane module to predict permeate flux and temperature distributions. The ratio of permeate flux enhancement to energy consumption increment, as referred to an assessment on economic viewpoint and technical feasibilities, was calculated to determine the suitable design parameters for DCMD operations with the insertion of S-ribs carbon-fiber turbulence promoters. An economic analysis was also performed, weighing both permeate flux improvement and energy consumption increment on modules with promoter-filled channels by different array configurations and various hydraulic diameters of turbulence promoters. Results showed that the ratio of permeate flux improvement to energy consumption increment in descending hydraulic-diameter modules is higher than in uniform hydraulic-diameter modules. The fabrication details of the DCMD module filaments implementing the S-ribs carbon-fiber filaments and the schematic configuration of the flat-plate DCMD experimental setup with presenting acrylic plates as external walls were demonstrated in the present study. The S-ribs carbon fibers perform as turbulence promoters incorporated into the artificial hot saline feed stream, which was prepared by adding inorganic salts (NaCl) to distilled water. Theoretical predictions and experimental results exhibited a great accomplishment to considerably achieve permeate flux enhancement, such as the new design of the DCMD module with inserting S-ribs carbon-fiber promoters. Additionally, the Nusselt number for the water vapor transferring membrane module with inserted S-ribs carbon-fiber promoters was generalized into a simplified expression to predict the heat transfer coefficient and permeate flux as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permeate%20flux" title="permeate flux">permeate flux</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusselt%20number" title=" Nusselt number"> Nusselt number</a>, <a href="https://publications.waset.org/abstracts/search?q=DCMD%20module" title=" DCMD module"> DCMD module</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20polarization" title=" temperature polarization"> temperature polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20diameters" title=" hydraulic diameters"> hydraulic diameters</a> </p> <a href="https://publications.waset.org/abstracts/194162/investigation-of-permeate-flux-through-dcmd-module-by-inserting-s-ribs-carbon-fiber-promoters-with-ascending-and-descending-hydraulic-diameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194162.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">8</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">29293</span> Long Hours Impact on Work-Life Balance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syeda%20Faiza%20Gardazi">Syeda Faiza Gardazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Ahsan%20Ali%20Gardazi"> Syed Ahsan Ali Gardazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajmal%20Waheed"> Ajmal Waheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The trend of overtime is increasing among workers due to more pressure to perform workloads, job insecurity, and financial issues. Overtime work affects the work-life balance conflict negatively as well positively. Work-life balance conflict has become an important issue as traditional work and family roles have changed. The purpose of the current research was to study the impact of overtime work on work-life balance conflict along with the moderating role of job satisfaction. For this purpose, data is collected from the employees working in different public and private sectors of Pakistan using simple random sampling technique. Descriptive statistics was used for data presentation and analysis. Correlation and regression analysis were used to test four research hypotheses proposed on the basis of research framework. The findings led to the acceptance of four hypotheses. The results show that high working hours and overtime in general lead to high work-life balance conflict.

It is clear that the diffusion of flux cannot be instantaneous and should be some time delay in this propagation. But Fick’s first law doesn’t consider this delay which results in some errors especially when there is a considerable time delay in the process. In this paper, we introduce a time delay to Fick’s first law. By this modification, we consider that the diffusion of flux cannot be instantaneous. In order to verify this claim an application sample in fluid diffusion is discussed and the results of modified Fick’s first law, Fick’s first law and the experimental results are compared. The results of this comparison stand for the accuracy of the modified model. The modified model can be used in any application where the time delay has considerable value and neglecting its effect reflects in undesirable results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fick%27s%20first%20law" title="Fick's first law">Fick's first law</a>, <a href="https://publications.waset.org/abstracts/search?q=flux" title=" flux"> flux</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion" title=" diffusion"> diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20delay" title=" time delay"> time delay</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20Fick%E2%80%99s%20first%20law" title=" modified Fick’s first law"> modified Fick’s first law</a> </p> <a href="https://publications.waset.org/abstracts/19767/modification-of-ficks-first-law-by-introducing-the-time-delay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19767.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">407</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">29290</span> Static Balance in the Elderly: Comparison Between Elderly Performing Physical Activity and Fine Motor Coordination Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andreia%20%20Guimaraes%20Farnese">Andreia Guimaraes Farnese</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateus%20Fernandes%20Reu%20Urban"> Mateus Fernandes Reu Urban</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Procopio"> Leandro Procopio</a>, <a href="https://publications.waset.org/abstracts/search?q=Renato%20Zangaro"> Renato Zangaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Regiane%20Albertini"> Regiane Albertini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Senescence changes include postural balance, inferring the risk of falls, and can lead to fractures, bedridden, and the risk of death. Physical activity, e.g., cardiovascular exercises, is notable for improving balance due to brain cell stimulations, but fine coordination exercises also elevate cell brain metabolism. This study aimed to verify whether the elderly person who performs fine motor activity has a balance similar to that of those who practice physical activity. The subjects were divided into three groups according to the activity practice: control group (CG) with seven participants for the sedentary individuals, motor coordination group (MCG) with six participants, and activity practitioner group (PAG) with eight participants. Data comparisons were from the Berg balance scale, Time up and Go test, and stabilometric analysis. Descriptive statistical and ANOVA analyses were performed for data analysis. The results reveal that including fine motor activities can improve the balance of the elderly and indirectly decrease the risk of falls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=barapodometer" title=" barapodometer"> barapodometer</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination" title=" coordination"> coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly" title=" elderly"> elderly</a> </p> <a href="https://publications.waset.org/abstracts/134990/static-balance-in-the-elderly-comparison-between-elderly-performing-physical-activity-and-fine-motor-coordination-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134990.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">168</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">29289</span> Efficient Estimation of Maximum Theoretical Productivity from Batch Cultures via Dynamic Optimization of Flux Balance Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20C.%20St.%20John">Peter C.

However, strategies for strain design typically involve designing mutations to achieve the highest yield possible while maintaining growth viability. Such approaches tend to follow the principle of designing static networks with minimum metabolic functionality to achieve desired yields. While these methods are computationally tractable, optimum productivity is likely achieved by a dynamic strategy, in which intracellular fluxes change their distribution over time. One can use multi-stage fermentations to increase either productivity or yield. Such strategies would range from simple manipulations (aerobic growth phase, anaerobic production phase), to more complex genetic toggle switches. Additionally, some computational methods can also be developed to aid in optimizing two-stage fermentation systems. One can assume an initial control strategy (i.e., a single reaction target) in maximizing productivity - but it is unclear how close this productivity would come to a global optimum. The calculation of maximum theoretical yield in metabolic engineering can help guide strain and pathway selection for static strain design efforts. Here, we present a method for the calculation of a maximum theoretical productivity of a batch culture system. This method follows the traditional assumptions of dynamic flux balance analysis: that internal metabolite fluxes are governed by a pseudo-steady state and external metabolite fluxes are represented by dynamic system including Michealis-Menten or hill-type regulation. The productivity optimization is achieved via dynamic programming, and accounts explicitly for an arbitrary number of fermentation stages and flux variable changes. We have applied our method to succinate production in two common microbial hosts: E. coli and A. succinogenes. The method can be further extended to calculate the complete productivity versus yield Pareto surface. Our results demonstrate that nearly optimal yields and productivities can indeed be achieved with only two discrete flux stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20succinogenes" title="A. succinogenes">A. succinogenes</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20coli" title=" E. coli"> E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20engineering" title=" metabolic engineering"> metabolic engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolite%20fluxes" title=" metabolite fluxes"> metabolite fluxes</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-stage%20fermentations" title=" multi-stage fermentations"> multi-stage fermentations</a>, <a href="https://publications.waset.org/abstracts/search?q=succinate" title=" succinate"> succinate</a> </p> <a href="https://publications.waset.org/abstracts/55861/efficient-estimation-of-maximum-theoretical-productivity-from-batch-cultures-via-dynamic-optimization-of-flux-balance-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55861.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">215</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">29288</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.
