The obtained results of above-mentioned methods were compared together. The study shows reasonable accordance with results of the all methods unless for two sections of tunnel. In these two sections there are some significant discrepancies between numerical and analytical results mainly originated from model geometry and high overburden. SGR and the analytical and numerical calculations, confirm the high concentration of seepage inflow in fault zones. Maximum seepage flow into tunnel has been estimated 0.425 lit/sec/m using analytical method and 0.628 lit/sec/m using numerical method occurred in crashed zone. Based on SGR method, six sections of 14 sections in Amirkabir tunnel axis are found to be in "No Risk" class that is supported by the analytical and numerical seepage value of less than 0.04 lit/sec/m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20Seepage" title="water Seepage">water Seepage</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirkabir%20Tunnel" title=" Amirkabir Tunnel"> Amirkabir Tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20method" title=" analytical method"> analytical method</a>, <a href="https://publications.waset.org/abstracts/search?q=DEM" title=" DEM"> DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=SGR" title=" SGR"> SGR</a> </p> <a href="https://publications.waset.org/abstracts/26677/groundwater-seepage-estimation-into-amirkabir-tunnel-using-analytical-methods-and-dem-and-sgr-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26677.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">476</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">51014</span> Current Situation and Need in Learning Management for Developing the Analytical Thinking of Teachers in Basic Education of Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Art-in">S.

The process is completed by first bending the metal plates statically and then dynamic roller bending sequentially. It is required to have an analytical model to get maximum bending force, for optimum design of the machine, for static bending stage. Analytical models assuming various stress conditions are considered and these analytical models are compared considering various parameters and reported in this paper. It is concluded from the study that for higher bottom roller inclination, the shear stress affects greatly to the static bending force whereas for lower bottom roller inclination it can be neglected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roller-bending" title="roller-bending">roller-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=static-bending" title=" static-bending"> static-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-conditions" title=" stress-conditions"> stress-conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical-modeling" title=" analytical-modeling"> analytical-modeling</a> </p> <a href="https://publications.waset.org/abstracts/45482/a-comparative-study-of-force-prediction-models-during-static-bending-stage-for-3-roller-cone-frustum-bending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45482.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">251</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">51012</span> An Analysis on Thermal Energy Storage in Paraffin-Wax Using Tube Array on a Shell and Tube Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syukri%20Himran">Syukri Himran</a>, <a href="https://publications.waset.org/abstracts/search?q=Rustan%20Taraka"> Rustan Taraka</a>, <a href="https://publications.waset.org/abstracts/search?q=Anto%20Duma"> Anto Duma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study is to improve the understanding of latent and sensible thermal energy storage within a paraffin wax media by an array of cylindrical tubes arranged both in in-line and staggered layouts. An analytical and experimental study was carried out in a horizontal shell-and-tube type system during the melting process. Pertamina paraffin-wax was used as a phase change material (PCM), where as the tubes are embedded in the PCM. From analytical study we can obtain the useful information in designing a thermal energy storage such as : the motion of interface, amount of material melted at any time in the process, and the heat storage characteristic during melting. The use of staggered tubes is proposed as superior to in-line layout for thermal storage. The experimental study was used to verify the validity of the analytical predictions. From the comparisons, the analytical and experimental data are in a good agreement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=latent" title="latent">latent</a>, <a href="https://publications.waset.org/abstracts/search?q=sensible" title=" sensible"> sensible</a>, <a href="https://publications.waset.org/abstracts/search?q=paraffin-wax" title=" paraffin-wax"> paraffin-wax</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title=" thermal energy storage"> thermal energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=conduction" title=" conduction"> conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a> </p> <a href="https://publications.waset.org/abstracts/35962/an-analysis-on-thermal-energy-storage-in-paraffin-wax-using-tube-array-on-a-shell-and-tube-heat-exchanger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35962.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">568</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">51011</span> Analytical Solution for Stellar Distance Based on Photon Dominated Cosmic Expansion Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoyun%20Li">Xiaoyun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Suoang%20Longzhou"> Suoang Longzhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper derives the analytical solution of stellar distance according to its redshift based on the photon-dominated universe expansion model. Firstly, it calculates stellar separation speed and the farthest distance of observable stars via simulation. Then the analytical solution of stellar distance according to its redshift is derived. It shows that when the redshift is large, the stellar distance (and its separation speed) is not proportional to its redshift due to the relativity effect. It also reveals the relationship between stellar age and its redshift. The correctness of the analytical solution is verified by the latest astronomic observations of Ia supernovas in 2020. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=redshift" title="redshift">redshift</a>, <a href="https://publications.waset.org/abstracts/search?q=cosmic%20expansion%20model" title=" cosmic expansion model"> cosmic expansion model</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=stellar%20distance" title=" stellar distance"> stellar distance</a> </p> <a href="https://publications.waset.org/abstracts/132729/analytical-solution-for-stellar-distance-based-on-photon-dominated-cosmic-expansion-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132729.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">161</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">51010</span> Computational Fluid Dynamics Analysis of Convergent–Divergent Nozzle and Comparison against Theoretical and Experimental Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stewart%20A.%20Keir">Stewart A.

The geometry used in the analytical study and CFD model is taken from the experimental rig. The analytical study is undertaken using isentropic and adiabatic relationships and the output of the analytical study, the 'shockwave location tool', is created. The results from the analytical study are then used to optimize the redesign an experimental rig for more favorable placement of pressure taps and gain a much better representation of the shockwaves occurring in the divergent section of the nozzle. The CFD model is then optimized through the selection of different parameters, e.g. turbulence models (Spalart-Almaras, Realizable k-epsilon & Standard k-omega) in order to develop an accurate, robust model. The results from the CFD model can then be directly compared to experimental and analytical results in order to gauge the accuracy of each method of analysis. The CFD model will be used to visualize the variation of various parameters such as velocity/Mach number, pressure and turbulence across the shock. The CFD results will be used to investigate the interaction between the shock wave and the boundary layer. The validated model can then be used to modify the nozzle designs which may offer better performance and ease of manufacture and may present feasible improvements to existing high-speed flow applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzle" title=" nozzle"> nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent" title=" fluent"> fluent</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20dynamics" title=" gas dynamics"> gas dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=shock-wave" title=" shock-wave"> shock-wave</a> </p> <a href="https://publications.waset.org/abstracts/70928/computational-fluid-dynamics-analysis-of-convergent-divergent-nozzle-and-comparison-against-theoretical-and-experimental-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70928.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">233</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">51009</span> Applications of Analytical Probabilistic Approach in Urban Stormwater Modeling in New Zealand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asaad%20Y.%20Shamseldin">Asaad Y.

It can provide information about the long-term performance of a stormwater management facility without being computationally very demanding. This paper explores the application of the analytical probabilistic approach in New Zealand. The paper presents the results of a case study aimed at development of an objective way of identifying what constitutes a rainfall storm event and the estimation of the corresponding statistical properties of storms using two selected automatic rainfall stations located in the Auckland region in New Zealand. The storm identification and the estimation of the storm statistical properties are regarded as the first step in the development of the analytical probabilistic models. The paper provides a recommendation about the definition of the storm inter-event time to be used in conjunction with the analytical probabilistic approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrology" title="hydrology">hydrology</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall%20storm" title=" rainfall storm"> rainfall storm</a>, <a href="https://publications.waset.org/abstracts/search?q=storm%20inter-event%20time" title=" storm inter-event time"> storm inter-event time</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20Zealand" title=" New Zealand"> New Zealand</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20management" title=" stormwater management "> stormwater management </a> </p> <a href="https://publications.waset.org/abstracts/29942/applications-of-analytical-probabilistic-approach-in-urban-stormwater-modeling-in-new-zealand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29942.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51008</span> Eco Scale: A Tool for Assessing the Greenness of Pharmaceuticals Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heba%20M.%20Mohamed">Heba M.

Subsequently, researchers’ attention is drawn in the direction of greening the analytical methodologies and taking the Green Analytical Chemistry principles (GAC) into consideration. It is of high importance to appraise the environmental impact of each of the implemented green approaches. Compared to the other traditional green metrics (E-factor, Atom economy and the process profile), the eco scale is the optimum choice to assess the environmental impact of the analytical procedures used for pharmaceuticals analysis. For analytical methodologies, Eco-Scale is calculated by allotting penalty points to any factor of the used analytical procedure which disagree and not match with the model green analysis, where the perfect green analysis has its Eco-Scale value of 100. In this work, calculation and comparison of the Eco-Scale for some of the reported green analytical methods was done, to accentuate their greening potentials. Where the different scores can reveal how green the method is, compared to the ideal value. The study emphasizes that greenness measurement is not only about the waste quantity determination but also dictates a holistic scheme, considering all factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco%20scale" title="eco scale">eco scale</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20analysis" title=" green analysis"> green analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=environmentally%20friendly" title=" environmentally friendly"> environmentally friendly</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticals%20analysis" title=" pharmaceuticals analysis"> pharmaceuticals analysis</a> </p> <a href="https://publications.waset.org/abstracts/21750/eco-scale-a-tool-for-assessing-the-greenness-of-pharmaceuticals-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21750.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">438</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">51007</span> Full Analytical Procedure to Derive P-I Diagram of a Steel Beam under Blast Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Hamra">L.

We develop a full analytical procedure that provides the ductility demand as a function of these six dimensionless parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20procedure" title="analytical procedure">analytical procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20loading" title=" blast loading"> blast loading</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20force" title=" membrane force"> membrane force</a>, <a href="https://publications.waset.org/abstracts/search?q=P-I%20diagram" title=" P-I diagram"> P-I diagram</a> </p> <a href="https://publications.waset.org/abstracts/13731/full-analytical-procedure-to-derive-p-i-diagram-of-a-steel-beam-under-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13731.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">427</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">51006</span> The Attitudes of Pre-Service Teachers towards Analytical Thinking Skill Development Based on Miller’s Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thassanant%20Unnanantn">Thassanant Unnanantn</a>, <a href="https://publications.waset.org/abstracts/search?q=Suttipong%20Boonphadung"> Suttipong Boonphadung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research study aimed to survey and analyze the attitudes of pre-service teachers’ the analytical thinking development based on Miller’s Model.

The instrument of this research was an open-ended questionnaire with two dimensions of questions: academic and satisfaction dimensions. The investigation revealed the positive attitudes. In the academic dimension, the majority of 12 (54.54%), the highest percentage, reflected that the method of teaching analytical thinking and language simultaneously was their new knowledge and the similar percentage also belonged to text cohesion in writing. For the satisfaction, the highest frequency count was from 17 of them (77.27%) and this majority favored the openness or friendliness of the teacher. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20thinking%20development" title="analytical thinking development">analytical thinking development</a>, <a href="https://publications.waset.org/abstracts/search?q=Miller%E2%80%99s%20Model" title=" Miller’s Model"> Miller’s Model</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teachers" title=" pre-service teachers"> pre-service teachers</a> </p> <a href="https://publications.waset.org/abstracts/18839/the-attitudes-of-pre-service-teachers-towards-analytical-thinking-skill-development-based-on-millers-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18839.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">309</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">51005</span> Analytical Model for Columns in Existing Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20Seok%20Lee">Chang Seok Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Whan%20Han"> Sang Whan Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Girbo%20Ko"> Girbo Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Debbie%20Kim"> Debbie Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Existing reinforced concrete structures are designed and built without considering seismic loads. The columns in such buildings generally exhibit widely spaced transverse reinforcements without using seismic hooks. Due to the insufficient reinforcement details in columns, brittle shear failure is expected in columns that may cause pre-mature building collapse mechanism during earthquakes. In order to retrofit those columns, the accurate seismic behavior of the columns needs to be predicted with proper analytical models. In this study, an analytical model is proposed for accurately simulating the cyclic behavior of shear critical columns. The parameters for pinching and cyclic deterioration in strength and stiffness are calibrated using test data of column specimens failed by shear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title="analytical model">analytical model</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20deterioration" title=" cyclic deterioration"> cyclic deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=existing%20reinforced%20concrete%20columns" title=" existing reinforced concrete columns"> existing reinforced concrete columns</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20failure" title=" shear failure"> shear failure</a> </p> <a href="https://publications.waset.org/abstracts/55636/analytical-model-for-columns-in-existing-reinforced-concrete-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55636.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">51004</span> Analytical Similarity Assessment of Bevacizumab Biosimilar Candidate MB02 Using Multiple State-of-the-Art Assays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marie-Elise%20Beydon">Marie-Elise Beydon</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Sacristan"> Daniel Sacristan</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Ruppen"> Isabel Ruppen </a> </p> <p class="card-text"><strong>Abstract:</strong></p> MB02 (Alymsys®) is a candidate biosimilar to bevacizumab, which was developed against the reference product (RP) Avastin® sourced from both the European Union (EU) and United States (US).

Reducing this force has always been the objective of hydrodynamic engineers to make water slide better on submerged bodies. This paper deals with the examination of the different terms composing the analytical solution of the flow over an obstacle embedded at the bottom of a hydraulic channel. We have chosen to use a linear method to study a two-dimensional flow over an obstacle, in order to understand the evolution of the drag. We set the following assumptions: incompressible inviscid fluid, irrotational flow, low obstacle height compared to the water height. Those assumptions allow overcoming the difficulties associated with modelling these waves. We will mathematically formulate the equations that allow the determination of the stream function, and then the free surface equation. A similar method is used to determine the exact analytical solution for an obstacle in the shape of a sinusoidal arch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title="analytical solution">analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=free-surface%20wave" title=" free-surface wave"> free-surface wave</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20channel" title=" hydraulic channel"> hydraulic channel</a>, <a href="https://publications.waset.org/abstracts/search?q=inviscid%20fluid" title=" inviscid fluid"> inviscid fluid</a> </p> <a href="https://publications.waset.org/abstracts/103580/contribution-to-the-analytical-study-of-barrier-surface-waves-decomposition-of-the-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103580.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">197</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">51002</span> Analytical Investigation on Seismic Behavior of Infilled Reinforced Concrete Frames Strengthened with Precast Diagonal Concrete Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceyhun%20Aksoylu">Ceyhun Aksoylu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rifat%20Sezer"> Rifat Sezer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a strengthening method applicable without any evacuation process was investigated.

The study was conducted through a survey questionnaire that was given to a random sample of 19 respondents (eight privately-owned and eleven government-owned hospitals), mainly CMTs, MTs, and Supervisors from UST-affiliated hospitals. The pre-analytical laboratory errors, which include misidentification errors, transcription errors, sample collection errors and sample handling and transportation errors, were considered as variables according to the IFCC WG-LEPS. Data gathered were analyzed using the Mann-Whitney U test, Percentile, Linear Regression, Percentage, and Frequency. The laboratory performance of both hospitals is High level. There is no significant difference between the laboratory performance between the two stated variables. Moreover, among the four QIs, sample handling and transportation errors contributed most to the difference between the two variables. Outcomes indicate satisfactory performance between both variables. However, in order to ensure high-quality and efficient laboratory operation, constant vigilance and improvements in pre-analytical QI are still needed. Expanding the coverage of the study, the inclusion of other phases, utilization of parametric tests are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-analytical%20phase" title="pre-analytical phase">pre-analytical phase</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20indicators" title=" quality indicators"> quality indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20performance" title=" laboratory performance"> laboratory performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-analytical%20error" title=" pre-analytical error"> pre-analytical error</a> </p> <a href="https://publications.waset.org/abstracts/137870/pre-analytical-laboratory-performance-evaluation-utilizing-quality-indicators-between-private-and-government-owned-hospitals-affiliated-to-university-of-santo-tomas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137870.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">146</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">51000</span> Analytical Investigation of Ductility of Reinforced Concrete Beams Strengthening with Polypropylene Fibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rifat%20Sezer">Rifat Sezer</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulhamid%20Aryan"> Abdulhamid Aryan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to research both the ductility of the reinforced concrete beams without fiber and the ductility of the reinforced concrete beams with fiber.

An additional supporting relation was applied based on a characteristic of condensation phenomenon for condensing elements. As it has been shown here, due to higher rates of heat transfer for elliptical tubes, they have more entropy production rates, in comparison to circular ones.

Material and Methods: All the lab specimens for diagnostic purposes received at the lab from Fauji Foundation hospital, Rawalpindi indoor and outdoor patients were included. Total number of samples received in the lab is recorded in the computerized program made for the hospital. All the errors observed for pre-analytical process including patient identification, sampling techniques, test collection procedures, specimen transport/processing and storage were recorded in the log book kept for the purpose. Results: A total of 476616 specimens were received in the lab during the period of study including 237931 and 238685 from outdoor and indoor patients respectively. Forty-one percent of the samples (n=197976) revealed pre-analytical discrepancies. The discrepancies included Hemolyzed samples (34.8%), Clotted blood (27.8%), Incorrect samples (17.4%), Unlabeled samples (8.9%), Insufficient specimens (3.9%), Request forms without authorized signature (2.9%), Empty containers (3.9%) and tube breakage during centrifugation (0.8%). Most of these pre-analytical discrepancies were observed in samples received from the wards revealing that inappropriate sample collection by the medical staff of the ward, as most of the outdoor samples are collected by the lab staff who are properly trained for sample collection. Conclusion: It is mandatory to educate phlebotomists and paramedical staff particularly performing duties in the wards regarding timing and techniques of sampling/appropriate container to use/early delivery of the samples to the lab to reduce pre-analytical errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre%20analytical%20lab%20errors" title="pre analytical lab errors">pre analytical lab errors</a>, <a href="https://publications.waset.org/abstracts/search?q=tertiary%20care%20hospital" title=" tertiary care hospital"> tertiary care hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=hemolyzed" title=" hemolyzed"> hemolyzed</a>, <a href="https://publications.waset.org/abstracts/search?q=paramedical%20staff" title=" paramedical staff"> paramedical staff</a> </p> <a href="https://publications.waset.org/abstracts/70067/overview-of-pre-analytical-lab-errors-in-a-tertiary-care-hospital-at-rawalpindi-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70067.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">204</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">50994</span> Integrations of Students' Learning Achievements and Their Analytical Thinking Abilities with the Problem-Based Learning and the Concept Mapping Instructional Methods on Gene and Chromosome Issue at the 12th Grade Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waraporn%20Thaimit">Waraporn Thaimit</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuwadee%20Insamran"> Yuwadee Insamran</a>, <a href="https://publications.waset.org/abstracts/search?q=Natchanok%20Jansawang"> Natchanok Jansawang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Focusing on Analytical Thinking and Learning Achievement are the critical component of visual thinking that gives one the ability to solve problems quickly and effectively that allows to complex problems into components, and the result had been achieved or acquired form of the subject students of which resulted in changes within the individual as a result of activity in learning.

The key point of this method lies in evaluation of the ker¬nels in the obtained integral equations by making use of a numerical technique. Once the structure of the kernel is defined, it then is approximated by an analytical expression of special kind so that the solution of the integral equation can be achieved analytically. This fact allows for construction of the solution in an analytical form, which is convenient for analysis of the mechanical effects concerned with arbitrarily presumed non-homogeneity of the material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20problem" title="contact problem">contact problem</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20punch" title=" circular punch"> circular punch</a>, <a href="https://publications.waset.org/abstracts/search?q=arbitrarily-nonhomogeneous%20halfspace" title=" arbitrarily-nonhomogeneous halfspace"> arbitrarily-nonhomogeneous halfspace</a> </p> <a href="https://publications.waset.org/abstracts/17693/a-semi-analytical-method-for-analysis-of-the-axially-symmetric-problem-on-indentation-of-a-hot-circular-punch-into-an-arbitrarily-nonhomogeneous-halfspace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17693.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">518</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">50992</span> Analytical Solution of Specific Energy Equation in Exponential Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Abdulrahman">Abdulrahman Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The specific energy equation has many applications in practical channels, such as exponential channels. In this paper, the governing equation of alternate depth ratio for exponential channels, in general, was investigated towards obtaining analytical solution for the alternate depth ratio in three exponential channel shapes, viz., rectangular, triangular, and parabolic channels. The alternate depth ratio for rectangular channels is quadratic; hence it is very simple to solve. While for parabolic and triangular channels, the alternate depth ratio is cubic and quartic equations, respectively, analytical solution for these equations may be achieved easily for a given Froud number. Different examples are solved to prove the efficiency of the proposed solution. Such analytical solution can be easily used in natural rivers and most of practical channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternate%20depth" title="alternate depth">alternate depth</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20energy" title=" specific energy"> specific energy</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20channel" title=" parabolic channel"> parabolic channel</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20channel" title=" rectangular channel"> rectangular channel</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20channel" title=" triangular channel"> triangular channel</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20channel%20flow" title=" open channel flow"> open channel flow</a> </p> <a href="https://publications.waset.org/abstracts/121104/analytical-solution-of-specific-energy-equation-in-exponential-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121104.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">198</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">50991</span> Analytical Solution of Blassius Equation Using the Kourosh Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Shahnazari">Mohammad Reza Shahnazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Kazemi"> Reza Kazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Saberi"> Ali Saberi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of the engineering problems are in nonlinear forms. Nonlinear boundary layer problems defined in infinite intervals contain specific complexities, especially in boundary layer condition conformance. As an example of these nonlinear complex problems, the well-known Blasius equation can be mentioned, which itself is one of the classic boundary layer problems. No analytical solution has been proposed yet for the Blasius equation due to its complexity. In this paper, an analytical method, namely the Kourosh method, based on the singularity perturbation method and the Liao homotopy analysis is utilized to solve the Blasius problem. In this method, an inner solution is developed in the [0,1] interval to expedite the solution convergence. The magnitude of the f ˝(0), as an essential quantity for determining the physical parameters, is directly calculated from the solution of the boundary condition problem. The advantages of this solution are that it does not need any numerical solution, it has a closed form and that its validation is shown in the entire [0,∞] interval. Furthermore, all of the desirable parameters could be extracted through a series of simple analytical operations from the final solution. This solution also satisfies the continuity conditions, which is one of the main contributions of this paper in comparison with most of the other proposed analytical solutions available in the literature. Comparison with numerical solutions reveals that the proposed method is highly accurate and convenient for application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blasius%20equation" title="Blasius equation">Blasius equation</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer" title=" boundary layer"> boundary layer</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20method" title=" Kourosh method"> Kourosh method</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a> </p> <a href="https://publications.waset.org/abstracts/49142/analytical-solution-of-blassius-equation-using-the-kourosh-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49142.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">391</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">50990</span> Finding the Elastic Field in an Arbitrary Anisotropic Media by Implementing Accurate Generalized Gaussian Quadrature Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Kabir">Hossein Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hossein%20Hassanpour%20Mati-Kolaie"> Amir Hossein Hassanpour Mati-Kolaie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current study, the elastic field in an anisotropic elastic media is determined by implementing a general semi-analytical method. In this specific methodology, the displacement field is computed as a sum of finite functions with unknown coefficients. These aforementioned functions satisfy exactly both the homogeneous and inhomogeneous boundary conditions in the proposed media. It is worth mentioning that the unknown coefficients are determined by implementing the principle of minimum potential energy. The numerical integration is implemented by employing the Generalized Gaussian Quadrature solution. Furthermore, with the aid of the calculated unknown coefficients, the displacement field, as well as the other parameters of the elastic field, are obtainable as well.

An experimental study of the cyclic nonlinear behavior of SC walls in the NEES laboratory at the University at Buffalo used a connection detail involving the post-tensioning of a steel baseplate to the SC wall to a RC foundation. This type of connection introduces flexibility that influenced substantially the global response of the SC walls. The assumption of a rigid base, which would be commonly made by practitioners, would lead to a substantial overestimation of initial stiffness. This paper presents an analytical approach to characterize the rotational flexibility and to predict the initial stiffness of flexure-critical SC wall piers with baseplate connection. The good agreement between the analytical and test results confirmed the utility of the proposed method for calculating the initial stiffness of an SC wall with baseplate connection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel-plate%20composite%20shear%20wall" title="steel-plate composite shear wall">steel-plate composite shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=flexure-critical%20wall" title="flexure-critical wall">flexure-critical wall</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title=" analytical model"> analytical model</a> </p> <a href="https://publications.waset.org/abstracts/25769/a-numerical-study-on-the-connection-of-an-sc-wall-to-an-rc-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25769.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">340</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">50986</span> Application of Analytical Method for Placement of DG Unit for Loss Reduction in Distribution Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20V.%20Siva%20Krishna%20Rao">G.
