Concerning 3D-CRT treatment planning, the MUVC can be performed manually applying the standard ESTRO formalism. However, due to the complex shape and the amount of beams in advanced treatment planning technic such as RapidArc, the manual independent MUVC is inadequate. Therefore, commercially available software such as RadCalc can be used to perform the MUVC in complex treatment planning been. Indeed, RadCalc (version 6.3 LifeLine Inc.) uses a simplified Clarkson algorithm to compute the dose contribution for individual RapidArc fields to the isocenter. The purpose of this project is the validation of RadCalc in 3D-CRT and RapidArc for treatment planning dosimetry quality assurance at Antoine Lacassagne center (Nice, France). Firstly, the interfaces between RadCalc and our treatment planning systems (TPS) Isogray (version 4.2) and Eclipse (version13.6) were checked for data transfer accuracy. Secondly, we created test plans in both Isogray and Eclipse featuring open fields, wedges fields, and irregular MLC fields. These test plans were transferred from TPSs according to the radiotherapy protocol of DICOM RT to RadCalc and the linac via Mosaiq (version 2.5). Measurements were performed in water phantom using a PTW cylindrical semiflex ionisation chamber (0.3 cm³, 31010) and compared with the TPSs and RadCalc calculation. Finally, 30 3D-CRT plans and 40 RapidArc plans created with patients CT scan were recalculated using the CT scan of a solid PMMA water equivalent phantom for 3D-CRT and the Octavius II phantom (PTW) CT scan for RapidArc. Next, we measure the doses delivered into these phantoms for each plan with a 0.3 cm³ PTW 31010 cylindrical semiflex ionisation chamber (3D-CRT) and 0.015 cm³ PTW PinPoint ionisation chamber (Rapidarc). For our test plans, good agreements were found between calculation (RadCalc and TPSs) and measurement (mean: 1.3%; standard deviation: ± 0.8%). Regarding the patient plans, the measured doses were compared to the calculation in RadCalc and in our TPSs. Moreover, RadCalc calculations were compared to Isogray and Eclispse ones. Agreements better than (2.8%; ± 1.2%) were found between RadCalc and TPSs. As for the comparison between calculation and measurement the agreement for all of our plans was better than (2.3%; ± 1.1%). The independent MU verification calculation software RadCal has been validated for clinical use and for both 3D-CRT and RapidArc techniques. The perspective of this project includes the validation of RadCal for the Tomotherapy machine installed at centre Antoine Lacassagne. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20conformational%20radiotherapy" title="3D conformational radiotherapy">3D conformational radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity%20modulated%20radiotherapy" title=" intensity modulated radiotherapy"> intensity modulated radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=monitor%20unit%20calculation" title=" monitor unit calculation"> monitor unit calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimetry%20quality%20assurance" title=" dosimetry quality assurance"> dosimetry quality assurance</a> </p> <a href="https://publications.waset.org/abstracts/78071/the-validation-of-radcalc-for-clinical-use-an-independent-monitor-unit-verification-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78071.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">4382</span> Improved Structure and Performance by Shape Change of Foam Monitor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae%20Gwan%20Kim">Tae Gwan Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyu%20Cho"> Hyun Kyu Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Hoon%20Lee"> Young Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Chul%20Park"> Young Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Foam monitors are devices that are installed on cargo tank decks to suppress cargo area fires in oil tankers or hazardous chemical ship cargo ships. In general, the main design parameter of the foam monitor is the distance of the projection through the foam monitor. In this study, the relationship between flow characteristics and projection distance, depending on the shape was examined. Numerical techniques for fluid analysis of foam monitors have been developed for prediction. The flow pattern of the fluid varies depending on the shape of the flow path of the foam monitor, as the flow losses affecting projection distance were calculated through numerical analysis. The basic shape of the foam monitor was an L shape designed by N Company. The modified model increased the length of the flow path and used the S shape model. The calculation result shows that the L shape, which is the basic shape, has a problem that the force is directed to one side and the vibration and noise are generated there. In order to solve the problem, S-shaped model, which is a change model, was used. As a result, the problem is solved, and the projection distance from the nozzle is improved. <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=foam%20monitor" title=" foam monitor"> foam monitor</a>, <a href="https://publications.waset.org/abstracts/search?q=projection%20distance" title=" projection distance"> projection distance</a>, <a href="https://publications.waset.org/abstracts/search?q=moment" title=" moment"> moment</a> </p> <a href="https://publications.waset.org/abstracts/66229/improved-structure-and-performance-by-shape-change-of-foam-monitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66229.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">343</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">4381</span> Engineering Thermal-Hydraulic Simulator Based on Complex Simulation Suite “Virtual Unit of Nuclear Power Plant”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evgeny%20Obraztsov">Evgeny Obraztsov</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilya%20Kremnev"> Ilya Kremnev</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitaly%20Sokolov"> Vitaly Sokolov</a>, <a href="https://publications.waset.org/abstracts/search?q=Maksim%20Gavrilov"> Maksim Gavrilov</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgeny%20Tretyakov"> Evgeny Tretyakov</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Kukhtevich"> Vladimir Kukhtevich</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Bezlepkin"> Vladimir Bezlepkin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decade, a specific set of connected software tools and calculation codes has been gradually developed. It allows simulating I&C systems, thermal-hydraulic, neutron-physical and electrical processes in elements and systems at the Unit of NPP (initially with WWER (pressurized water reactor)). In 2012 it was called a complex simulation suite “Virtual Unit of NPP” (or CSS “VEB” for short). Proper application of this complex tool should result in a complex coupled mathematical computational model. And for a specific design of NPP, it is called the Virtual Power Unit (or VPU for short). VPU can be used for comprehensive modelling of a power unit operation, checking operator's functions on a virtual main control room, and modelling complicated scenarios for normal modes and accidents. In addition, CSS “VEB” contains a combination of thermal hydraulic codes: the best-estimate (two-liquid) calculation codes KORSAR and CORTES and a homogenous calculation code TPP. So to analyze a specific technological system one can build thermal-hydraulic simulation models with different detalization levels up to a nodalization scheme with real geometry. And the result at some points is similar to the notion “engineering/testing simulator” described by the European utility requirements (EUR) for LWR nuclear power plants. The paper is dedicated to description of the tools mentioned above and an example of the application of the engineering thermal-hydraulic simulator in analysis of the boron acid concentration in the primary coolant (changed by the make-up and boron control system). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=best-estimate%20code" title="best-estimate code">best-estimate code</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20simulation%20suite" title=" complex simulation suite"> complex simulation suite</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20simulator" title=" engineering simulator"> engineering simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant" title=" power plant"> power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20hydraulic" title=" thermal hydraulic"> thermal hydraulic</a>, <a href="https://publications.waset.org/abstracts/search?q=VEB" title=" VEB"> VEB</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20power%20unit" title=" virtual power unit"> virtual power unit</a> </p> <a href="https://publications.waset.org/abstracts/63791/engineering-thermal-hydraulic-simulator-based-on-complex-simulation-suite-virtual-unit-of-nuclear-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63791.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">380</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">4380</span> Optimal Opportunistic Maintenance Policy for a Two-Unit System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nooshin%20Salari">Nooshin Salari</a>, <a href="https://publications.waset.org/abstracts/search?q=Viliam%20Makis"> Viliam Makis</a>, <a href="https://publications.waset.org/abstracts/search?q=Jane%20Doe"> Jane Doe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a maintenance policy for a system consisting of two units. Unit 1 is gradually deteriorating and is subject to soft failure. Unit 2 has a general lifetime distribution and is subject to hard failure. Condition of unit 1 of the system is monitored periodically and it is considered as failed when its deterioration level reaches or exceeds a critical level N. At the failure time of unit 2 system is considered as failed, and unit 2 will be correctively replaced by the next inspection epoch. Unit 1 or 2 are preventively replaced when deterioration level of unit 1 or age of unit 2 exceeds the related preventive maintenance (PM) levels. At the time of corrective or preventive replacement of unit 2, there is an opportunity to replace unit 1 if its deterioration level reaches the opportunistic maintenance (OM) level. If unit 2 fails in an inspection interval, system stops operating although unit 1 has not failed. A mathematical model is derived to find the preventive and opportunistic replacement levels for unit 1 and preventive replacement age for unit 2, that minimize the long run expected average cost per unit time. The problem is formulated and solved in the semi-Markov decision process (SMDP) framework. Numerical example is provided to illustrate the performance of the proposed model and the comparison of the proposed model with an optimal policy without opportunistic maintenance level for unit 1 is carried out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition-based%20maintenance" title="condition-based maintenance">condition-based maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunistic%20maintenance" title=" opportunistic maintenance"> opportunistic maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=preventive%20maintenance" title=" preventive maintenance"> preventive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=two-unit%20system" title=" two-unit system"> two-unit system</a> </p> <a href="https://publications.waset.org/abstracts/62311/optimal-opportunistic-maintenance-policy-for-a-two-unit-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62311.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">200</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">4379</span> Cogeneration Unit for Small Stove</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michal%20Spilacek">Michal Spilacek</a>, <a href="https://publications.waset.org/abstracts/search?q=Marian%20Brazdil"> Marian Brazdil</a>, <a href="https://publications.waset.org/abstracts/search?q=Otakar%20Stelcl"> Otakar Stelcl</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiri%20Pospisil"> Jiri Pospisil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper shows an experimental testing of a small unit for combustion of solid fuels, such as charcoal and wood logs, that can provide electricity.

This system has been implemented in purpose of quality and expenditure control, i.e., controlling health overpayment to obtain benefit (moral hazard) by the user of insurance or health service provider. The increasing health cost becomes the main issue that hampers the society to receive required health service in cash payment-system. One of the efforts that should be taken by the government in health payment is by securing health insurance through society's health insurance. The objective of the study is to learn the capability of a patient to pay cataract eye operation for the elders. Method of study sample population in this study was patients who obtain health insurance board card for the society that was started in the first of tri-semester (January-March) 2015 and claimed in Indonesian software-Case Based Group as a purposive sampling of 40 patients. Results of the study show that total unit cost analysis of surgery service unit was obtained $75 for unit cost without AFC and salary of nurse and doctor. The operation tariff that has been implemented today at Anutapura hospitals in eye department is tariff without AFC and the salary of the employee is $80. The operation tariff of the unit cost calculation with double distribution model at $65. Conclusion, the calculation result of actual unit cost that is much greater causes incentive distribution system provided to an ophthalmologist at $37 and nurse at $20 for one operation. The surgery service tariff is still low; consequently, the hospital receives low revenue and the quality of health insurance in eye operation department is relatively low. In purpose of increasing the service quality, it requires adequately high cost to equip medical equipment and increase the number of professional health attendant in serving patients in cataract eye operation at hospital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20evaluation" title="economic evaluation">economic evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=cataract%20operation" title=" cataract operation"> cataract operation</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20attendant" title=" health attendant"> health attendant</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20insurance%20system" title=" health insurance system"> health insurance system</a> </p> <a href="https://publications.waset.org/abstracts/82660/economic-evaluation-of-cataract-eye-surgery-by-health-attendant-of-doctor-and-nurse-through-the-social-insurance-board-cadr-at-general-hospital-anutapura-palu-central-sulawesi-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4377</span> A Comparison of Energy Calculations for a Single-Family Detached Home with Two Energy Simulation Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Sattari">Amir Sattari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For newly produced houses and energy renovations, an energy calculation needs to be conducted. This is done to verify whether the energy consumption criteria of the house -to reach the energy targets by 2020 and 2050- are in-line with the norms. The main purpose of this study is to confirm whether easy to use energy calculation software or hand calculations used by small companies or individuals give logical results compared to advanced energy simulation program used by researchers or bigger companies. There are different methods for calculating energy consumption. In this paper, two energy calculation programs are used and the relation of energy consumption with solar radiation is compared. A hand calculation is also done to validate whether the hand calculations are still reasonable. The two computer programs which have been used are TMF Energi (the easy energy calculation variant used by small companies or individuals) and IDA ICE - Indoor Climate and Energy (the advanced energy simulation program used by researchers or larger companies). The calculations are done for a standard house from the Swedish house supplier Fiskarhedenvillan. The method is based on having the same conditions and inputs in the different calculation forms so that the results can be compared and verified. The house has been faced differently to see how the orientation affects energy consumption in different methods. The results for the simulations are close to each other and the hand calculation differs from the computer programs by only 5%. Even if solar factors differ due to the orientation of the house, energy calculation results from different computer programs and even hand calculation methods are in line with each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20calculation" title="energy calculation">energy calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20simulation" title=" energy simulation"> energy simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=IDA%20ICE" title=" IDA ICE"> IDA ICE</a>, <a href="https://publications.waset.org/abstracts/search?q=TMF%20energi" title=" TMF energi"> TMF energi</a> </p> <a href="https://publications.waset.org/abstracts/112034/a-comparison-of-energy-calculations-for-a-single-family-detached-home-with-two-energy-simulation-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112034.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">115</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">4376</span> Studying Projection Distance and Flow Properties by Shape Variations of Foam Monitor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kyu%20Cho">Hyun-Kyu Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Su%20Kim"> Jun-Su Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon-Geun%20Huh"> Choon-Geun Huh</a>, <a href="https://publications.waset.org/abstracts/search?q=Geon%20Lee%20Young-Chul%20Park"> Geon Lee Young-Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the relationship between flow properties and fluid projection distance look into connection for shape variations of foam monitor.

A wide variety of phraseological units have been explored, including collocations, chunks, lexical bundles, patterns, semantic sequences, etc. This paper describes a special category of clause-level phraseological units, namely, Characteristic Sentence Stems (CSSs), with a view to describing their defining criteria and extraction method. CSSs are contiguous lexico-grammatical sequences which contain a subject-predicate structure and which are frame expressions characteristic of academic writing. The extraction of CSSs consists of six steps: Part-of-speech tagging, n-gram segmentation, structure identification, significance of occurrence calculation, text range calculation, and overlapping sequence reduction. Significance of occurrence calculation is the crux of this study. It includes the computing of both the internal association and the boundary independence of a CSS and tests the occurring significance of the CSS from both inside and outside perspectives. A new normalization algorithm is also introduced into the calculation of LocalMaxs for reducing overlapping sequences. It is argued that many sentence stems are so recurrent in academic texts that the most typical of them have become the habitual ways of making meaning in academic writing. Therefore, studies of CSSs could have potential implications and reference value for academic discourse analysis, English for Academic Purposes (EAP) teaching and writing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20sentence%20stem" title="characteristic sentence stem">characteristic sentence stem</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction%20method" title=" extraction method"> extraction method</a>, <a href="https://publications.waset.org/abstracts/search?q=phraseological%20unit" title=" phraseological unit"> phraseological unit</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20statistical%20measure" title=" the statistical measure"> the statistical measure</a> </p> <a href="https://publications.waset.org/abstracts/91742/characteristic-sentence-stems-in-academic-english-texts-definition-identification-and-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91742.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4373</span> Intelligent Wireless Patient Monitoring and Tracking System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ch.%20Sandeep%20Kumar%20Subudhi">Ch.

In our system the body temperature is detected by using LM35 temperature sensor, blood pressure is detected by the BP sensor, pulse rate is detected by the ear plug pulse sensor and the ECG is detected by the three lead ECG sensor in the working environment of the patient. The sensed information is sent to the PIC16F877 microcontroller through signal conditioning circuit. A desired amount of sensor value is set and if it is exceeded preliminary steps should be taken by indication by buzzer. The sensor information will be transmitted from the patient unit to the main controller unit with the help of Zigbee communication medium which is connected with the microcontrollers in the both units. The main controller unit will send those sensor data as well as the location of that patient by the help of GPS module to the observer/doctor. The observer/doctor can receive the SMS sent by GSM module and further decision can be taken. The message is sent to a cell phone using global system mobile (GSM) Modem.

Mobile code such as a mobile agent is vulnerable when executing on remote hosts. The mobile agent may be subjected to various attacks such as tampering, inspection, and replay attack by a malicious host. Much research has been done to provide solutions for various security problems, such as authentication of mobile agent and hosts, integrity and confidentiality of the data carried by the mobile agent. Many of such proposed solutions in literature are not suitable for open systems whereby the mobile code arrives and executes on a host which is not known and trusted by the mobile agent owner. In this paper, we propose the adoption of the reference monitor by hosts in an open system for providing trust and security for mobile code execution. A secure protocol for the distribution of the reference monitor entity is described. This reference monitor entity on the remote host may also provide several security services such as authentication and integrity to the mobile code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security" title="security">security</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20agents" title=" mobile agents"> mobile agents</a>, <a href="https://publications.waset.org/abstracts/search?q=reference%20monitor" title=" reference monitor"> reference monitor</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a> </p> <a href="https://publications.waset.org/abstracts/31788/mobile-agent-security-using-reference-monitor-based-security-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31788.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">440</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">4371</span> Study of NGL Feed Price Calculation for a Typical NGL Fractionation Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simin%20Eydivand">Simin Eydivand</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ghanadieslami"> Ali Ghanadieslami</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Amiri"> Reza Amiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural gas liquids (NGLs) are light hydrocarbons that are dissolved in associated or non‐associated natural gas in a hydrocarbon reservoir and are produced within a gas stream.

The first one improves heat and mass transfer by increasing cooled contact surface of gas and condensate drops and film formed in inner tubes heat exchanger. This paper presents a selection of significant factors which influence the heat and mass transfer. Experimental planning is based on the research and analysis of main three independent variables; velocity of water and gas as well as density of spraying. Empirical mathematical models show that the coefficient of heat transfer is used as dependent parameter which depends on two independent variables; water and gas velocity. Empirical model is proved by the use of experimental data of two independent gas condensing units in Lithuania and Russia.

The progressive dismantling of the large power plants and the ongoing construction of many new decentralized plants result in great potential for optimization through synergies between the individual plants. These potentials can be exploited by mathematical optimization algorithms to calculate the optimal application planning of decentralized power and heat generators and storage systems. This also includes linear or linear mixed integer optimization. In this paper, procedures for reducing the number of decision variables to be calculated are explained and validated. On the one hand, this includes combining n similar installation types into one aggregated unit. This aggregated unit is described by the same constraints and target function terms as a single plant. This reduces the number of decision variables per time step and the complexity of the problem to be solved by a factor of n. The exact operating mode of the individual plants can then be calculated in a second optimization in such a way that the output of the individual plants corresponds to the calculated output of the aggregated unit. Another way to reduce the number of decision variables in an optimization problem is to reduce the number of time steps to be calculated. This is useful if a high temporal resolution is not necessary for all time steps. For example, the volatility or the forecast quality of environmental parameters may justify a high or low temporal resolution of the optimization. Both approaches are examined for the resulting calculation time as well as for optimality. Several optimization models for virtual power plants (combined heat and power plants, heat storage, power storage, gas turbine) with different numbers of plants are used as a reference for the investigation of both processes with regard to calculation duration and optimality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CHP" title="CHP">CHP</a>, <a href="https://publications.waset.org/abstracts/search?q=Energy%204.0" title=" Energy 4.0"> Energy 4.0</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=MILP" title=" MILP"> MILP</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20power%20plant" title=" virtual power plant"> virtual power plant</a> </p> <a href="https://publications.waset.org/abstracts/95734/approaches-to-reduce-the-complexity-of-mathematical-models-for-the-operational-optimization-of-large-scale-virtual-power-plants-in-public-energy-supply" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95734.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">178</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">4364</span> Lighting Consumption Analysis in Retail Industry: Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20C.%20Tama%C5%9F">Elena C.

Some buildings have installed building management systems (BMS) to monitor also the lighting performances starting with the opening days till the present days but some have chosen only local meters to implement. Firstly, for each analyzed building, the total required energy power and the energy power consumption for lighting were calculated depending on the lamps number, the unit power and the average daily running hours. All objects and installations were chosen depending on the destination/location of the lighting (exterior parking or access, interior or covering parking, building interior and building perimeter). Secondly, to all lighting objects and installations, mechanical counters were installed, and to the ones linked to BMS there were installed the digital meters as well for a better monitoring. Some efficient solutions are proposed to improve the power consumption, for example the 1/3 lighting functioning for the covered and exterior parking lighting to those buildings if can be done. This type of lighting share can be performed on each level, especially on the night shifts. Another example is to use the dimmers to reduce the light level, depending on the executed work in the respective area, and a 30% power energy saving can be achieved. Using the right BMS to monitor, the energy consumption depending on the average operational daily hours and changing the non-performant unit lights with the ones having LED technology or economical ones might increase significantly the energy performances and reduce the energy consumption of the buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20buildings" title="commercial buildings">commercial buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20performances" title=" energy performances"> energy performances</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20consumption" title=" lightning consumption"> lightning consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a> </p> <a href="https://publications.waset.org/abstracts/87454/lighting-consumption-analysis-in-retail-industry-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87454.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">261</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">4363</span> Design and Analysis of Electric Power Production Unit for Low Enthalpy Geothermal Reservoir Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ildar%20Akhmadullin">Ildar Akhmadullin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayank%20Tyagi"> Mayank Tyagi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The subject of this paper is the design analysis of a single well power production unit from low enthalpy geothermal resources. A complexity of the project is defined by a low temperature heat source that usually makes such projects economically disadvantageous using the conventional binary power plant approach. A proposed new compact design is numerically analyzed. This paper describes a thermodynamic analysis, a working fluid choice, downhole heat exchanger (DHE) and turbine calculation results. The unit is able to produce 321 kW of electric power from a low enthalpy underground heat source utilizing n-Pentane as a working fluid. A geo-pressured reservoir located in Vermilion Parish, Louisiana, USA is selected as a prototype for the field application. With a brine temperature of 126℃, the optimal length of DHE is determined as 304.8 m (1000ft). All units (pipes, turbine, and pumps) are chosen from commercially available parts to bring this project closer to the industry requirements. Numerical calculations are based on petroleum industry standards. The project is sponsored by the Department of Energy of the US. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=downhole%20heat%20exchangers" title="downhole heat exchangers">downhole heat exchangers</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal%20power%20generation" title=" geothermal power generation"> geothermal power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20rankine%20cycle" title=" organic rankine cycle"> organic rankine cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigerants" title=" refrigerants"> refrigerants</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20fluids" title=" working fluids"> working fluids</a> </p> <a href="https://publications.waset.org/abstracts/10812/design-and-analysis-of-electric-power-production-unit-for-low-enthalpy-geothermal-reservoir-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10812.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">315</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">4362</span> Technological Ensuring of the Space Reflector Antennas Manufacturing Process from Carbon Fiber Reinforced Plastics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pyi%20Phyo%20Maung">Pyi Phyo Maung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the study, the calculations of the permeability coefficient, values of the volume and porosity of a unit cell of a woven fabric before and after deformation based on the geometrical parameters are presented. Two types of carbon woven fabric structures were investigated: standard type, which integrated the filament, has a cross sectional shape of a cylinder and spread tow type, which has a rectangular cross sectional shape. The space antennas reflector, which distinctive feature is the presence of the surface of double curvature, is considered as the object of the research. Modeling of the kinetics of the process of impregnation of the reflector for the two types of carbon fabric’s unit cell structures was performed using software RAM-RTM. This work also investigated the influence of the grid angle between warp and welt of the unit cell on the duration of impregnation process. The results showed that decreasing the angle between warp and welt of the unit cell, the decreasing of the permeability values were occurred. Based on the results of calculation samples of the reflectors, their quality was determined. The comparisons of the theoretical and experimental results have been carried out. Comparison of the two textile structures (standard and spread tow) showed that the standard textiles with circular cross section were impregnated faster than spread tows, which have a rectangular cross section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vacuum%20assistant%20resin%20infusion" title="vacuum assistant resin infusion">vacuum assistant resin infusion</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation%20time" title=" impregnation time"> impregnation time</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20angle" title=" shear angle"> shear angle</a>, <a href="https://publications.waset.org/abstracts/search?q=reflector%20and%20modeling" title=" reflector and modeling"> reflector and modeling</a> </p> <a href="https://publications.waset.org/abstracts/47083/technological-ensuring-of-the-space-reflector-antennas-manufacturing-process-from-carbon-fiber-reinforced-plastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4361</span> Development of a Fire Analysis Drone for Smoke Toxicity Measurement for Fire Prediction and Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabrielle%20Peck">Gabrielle Peck</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20Hayes"> Ryan Hayes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents the design and creation of a drone gas analyser, aimed at addressing the need for independent data collection and analysis of gas emissions during large-scale fires, particularly wasteland fires. The analyser drone, comprising a lightweight gas analysis system attached to a remote-controlled drone, enables the real-time assessment of smoke toxicity and the monitoring of gases released into the atmosphere during such incidents. The key components of the analyser unit included two gas line inlets connected to glass wool filters, a pump with regulated flow controlled by a mass flow controller, and electrochemical cells for detecting nitrogen oxides, hydrogen cyanide, and oxygen levels. Additionally, a non-dispersive infrared (NDIR) analyser is employed to monitor carbon monoxide (CO), carbon dioxide (CO₂), and hydrocarbon concentrations. Thermocouples can be attached to the analyser to monitor temperature, as well as McCaffrey probes combined with pressure transducers to monitor air velocity and wind direction. These additions allow for monitoring of the large fire and can be used for predictions of fire spread. The innovative system not only provides crucial data for assessing smoke toxicity but also contributes to fire prediction and management. The remote-controlled drone's mobility allows for safe and efficient data collection in proximity to the fire source, reducing the need for human exposure to hazardous conditions. The data obtained from the gas analyser unit facilitates informed decision-making by emergency responders, aiding in the protection of both human health and the environment. This abstract highlights the successful development of a drone gas analyser, illustrating its potential for enhancing smoke toxicity analysis and fire prediction capabilities. The integration of this technology into fire management strategies offers a promising solution for addressing the challenges associated with wildfires and other large-scale fire incidents. The project's methodology and results contribute to the growing body of knowledge in the field of environmental monitoring and safety, emphasizing the practical utility of drones for critical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20prediction" title="fire prediction">fire prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=drone" title=" drone"> drone</a>, <a href="https://publications.waset.org/abstracts/search?q=smoke%20toxicity" title=" smoke toxicity"> smoke toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=analyser" title=" analyser"> analyser</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20management" title=" fire management"> fire management</a> </p> <a href="https://publications.waset.org/abstracts/174836/development-of-a-fire-analysis-drone-for-smoke-toxicity-measurement-for-fire-prediction-and-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174836.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">89</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">4360</span> Small Scale Stationary and Mobile Production of Biodiesel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yusuf%20Abduh">Muhammad Yusuf Abduh</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Manurung"> Robert Manurung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hero%20Jan%20Heeres"> Hero Jan Heeres</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biodiesel can be produced in small scale mobile units which are designed with local input and demand. Unlike the typical biodiesel production plants, mobile biodiesel unit consiss of a biodiesel production facility placed inside a standard cargo container and mounted on a truck so that it can be transported to a region near the location of raw materials. In this paper, we review the existing concept and unit for the development of community-scale and mobile production of biodiesel. This includes the main reactor technology to produce biodiesel as well as the pre-treatment prior to the reaction unit. The pre-treatment includes the oil-expeller unit to obtain oil from the oilseeds as well as the quality control of the oil before it enters the reaction unit. This paper also discusses the post-treatment after the production of biodiesel. It includes the refining and purification of biodiesel to meet the product specification set by the biodiesel industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20scale" title=" community scale"> community scale</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20biodiesel%20unit" title=" mobile biodiesel unit"> mobile biodiesel unit</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20technology" title=" reactor technology"> reactor technology</a> </p> <a href="https://publications.waset.org/abstracts/85377/small-scale-stationary-and-mobile-production-of-biodiesel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85377.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">236</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">4359</span> Legal Basis for Water Resources Management in Brazil: Case Study of the Rio Grande Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jana%C3%ADna%20F.%20Guidolini">Janaína F.

The central issue that should govern the management is the integration of the various aspects that interfere with the use of water resources and their protection, supported by legal basis. A watershed is a unit of water interacting with the physical, biotic, social, economic and cultural variables. The Brazilian law recognized river basin as the territorial management unit. Based on the diagnosis of the current situation of the water resources of the Rio Grande Basin, a discussion informed in the Brazilian legal basis was made to propose measures to fight or mitigate damages and environmental degradation in the Basin. To manage water resources more efficiently, conserve water and optimize their multiple uses, the integration of acquired scientific knowledge and management is essential.

However, evidence of the influence of patients lifting behaviors and LBP among nurses in Saudi Arabia remains scarce. The purpose of this study was to investigate the relationship between LBP and nurses lifting behaviors. LBP questionnaire was distributed to 100 nurses working in Alsadairy Hospital distributed as Emergency unit(9),Coronary Care unit (9), Intensive Care Unit (7), Dialysis unit (30), Burn unit (5), surgical unit (11), Medical (14) and, X-ray unit (15). The questionnaire included demographic data, attitude scale, Team work scale, Back pain history and Knowledge scale. Regarding to emergency unit, there is appositive significant relation between teamwork scale and Knowledge as r = (0.807) and P =0.05. Regarding to ICU unit, there is a positive significant relation between teamwork scale and attitude scale as r= (0.781) and P =0.05. Regarding to Dialysis unit, there is a positive significant relation between attitude scale and teamwork scale as r=(0.443) and P =0.05. The findings suggest enhanced awareness of occupational safety with safe patient handling practices among nursing students must be emphasized and integrated into their educational curriculum. Moreover, back pain prevention program should incorporate the promotion of an active lifestyle and fitness training the implementation of institutional patient handling policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=lifting%20behaviors" title=" lifting behaviors"> lifting behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=team%20work" title=" team work "> team work </a> </p> <a href="https://publications.waset.org/abstracts/14949/low-back-pain-and-patients-lifting-behaviors-among-nurses-working-in-al-sadairy-hospital-aljouf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14949.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">435</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">4357</span> Robotic Solution for Nuclear Facility Safety and Monitoring System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Altab%20Hossain">Altab Hossain</a>, <a href="https://publications.waset.org/abstracts/search?q=Shakerul%20Islam"> Shakerul Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Golamur%20R.%20Khan"> Golamur R.

A great number of monitoring and diagnosis methodologies are applied and used worldwide in areas such as industry, automobiles, hospitals, and power plant to detect and reduce human disasters. The potential consequences of several hazardous activities may harm the society using nuclear and its associated facilities. Hence, one of the most popular and effective methods to ensure safety and monitor the entire nuclear facility and imply risk-free operation without human interference during the hazardous situation is using a robot. Therefore, in this study, an advanced autonomous robot has been designed and developed that can monitor several parameters in the NPP to ensure the safety and do some risky job in case of nuclear disaster. The robot consisted of autonomous track following unit, data processing and transmitting unit can follow a straight line and take turn as the bank greater than 90 degrees. The developed robot can analyze various parameters such as temperature, altitude, radiation, obstacle, humidity, detecting fire, measuring distance, ultrasonic scan and taking the heat of any particular object. It has an ability to broadcast live stream and can record the document to its own server memory. There is a separate control unit constructed with a baseboard which processes the recorded data and a transmitter which transmits the processed data. To make the robot user-friendly, the code is developed such a way that a user can control any of robotic arm as per types of work. To control at any place and without the track, there is an advanced code has been developed to take manual overwrite.

It mainly assumes the role of geospatial unit, assists in promoting the complex development of the business in Shenzhen and undertakes the management and transmission of upper and lower levels of planning as well as the Urban management functions such as gap analysis of public facilities, planning evaluation and dynamic monitoring of planning information. Combining with the application examples of the analysis of gaps in public facilities in Longgang District, it can be found that the standard unit of land spatial planning in Shenzhen as a small-scale geographic basic unit, has a stronger urban spatial coupling effect. However, the universality of the application of the system is still lacking and it is necessary to propose more scientific and powerful standard unit delineation standards and planning function evaluation indicators to guide the implementation of the system's popularization and application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shenzhen%20city" title="Shenzhen city">Shenzhen city</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20spatial%20planning" title=" land spatial planning"> land spatial planning</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20unit%20system" title=" standard unit system"> standard unit system</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20delicacy%20management" title=" urban delicacy management"> urban delicacy management</a> </p> <a href="https://publications.waset.org/abstracts/146407/overview-of-standard-unit-system-of-shenzhen-land-spatial-planning-and-case-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146407.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">128</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">4355</span> Improvement of Parallel Compressor Model in Dealing Outlet Unequal Pressure Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kewei%20Xu">Kewei Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jens%20Friedrich"> Jens Friedrich</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Dwinger"> Kevin Dwinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Fan"> Wei Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xijin%20Zhang"> Xijin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parallel Compressor Model (PCM) is a simplified approach to predict compressor performance with inlet distortions. In PCM calculation, it is assumed that the sub-compressors’ outlet static pressure is uniform and therefore simplifies PCM calculation procedure. However, if the compressor’s outlet duct is not long and straight, such assumption frequently induces error ranging from 10% to 15%. This paper provides a revised calculation method of PCM that can correct the error. The revised method employs energy equation, momentum equation and continuity equation to acquire needed parameters and replace the equal static pressure assumption. Based on the revised method, PCM is applied on two compression system with different blades types. The predictions of their performance in non-uniform inlet conditions are yielded through the revised calculation method and are employed to evaluate the method’s efficiency. Validating the results by experimental data, it is found that although little deviation occurs, calculated result agrees well with experiment data whose error ranges from 0.1% to 3%. Therefore, this proves the revised calculation method of PCM possesses great advantages in predicting the performance of the distorted compressor with limited exhaust duct. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20compressor%20model%20%28pcm%29" title="parallel compressor model (pcm)">parallel compressor model (pcm)</a>, <a href="https://publications.waset.org/abstracts/search?q=revised%20calculation%20method" title=" revised calculation method"> revised calculation method</a>, <a href="https://publications.waset.org/abstracts/search?q=inlet%20distortion" title=" inlet distortion"> inlet distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=outlet%20unequal%20pressure%20distribution" title=" outlet unequal pressure distribution"> outlet unequal pressure distribution</a> </p> <a href="https://publications.waset.org/abstracts/39155/improvement-of-parallel-compressor-model-in-dealing-outlet-unequal-pressure-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39155.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">331</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">4354</span> Wireless Based System for Continuous Electrocardiography Monitoring during Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Bensafia">K.

Haddab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a system designed for wireless acquisition, the recording of electrocardiogram (ECG) signals and the monitoring of the heart’s health during surgery. This wireless recording system allows us to visualize and monitor the state of the heart’s health during a surgery, even if the patient is moved from the operating theater to post anesthesia care unit. The acquired signal is transmitted via a Bluetooth unit to a PC where the data are displayed, stored and processed. To test the reliability of our system, a comparison between ECG signals processed by a conventional ECG monitoring system (Datex-Ohmeda) and by our wireless system is made. The comparison is based on the shape of the ECG signal, the duration of the QRS complex, the P and T waves, as well as the position of the ST segments with respect to the isoelectric line. The proposed system is presented and discussed. The results have confirmed that the use of Bluetooth during surgery does not affect the devices used and vice versa. Pre- and post-processing steps are briefly discussed. Experimental results are also provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocardiography"
