Based on linear thermoelastic theory, the equations of hyperbolic heat conduction and thermoelastic motion were combined to establish the thermoelastic dynamic model with consideration of the deformation acceleration effect and non-Fourier effect under the condition of transient thermal shock. The approximate solutions of temperature and displacement distributions are obtained using the residual correction method based on the maximum principle in combination with the finite difference method, making it easier and faster to obtain upper and lower approximations of exact solutions. The proposed method is found to be an effective numerical method with satisfactory accuracy. Moreover, the result shows that the effect of transient thermal shock induced by deformation acceleration is enhanced by non-Fourier heat conduction with increased peak stress. The influence on the stress increases with the thermal relaxation time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maximum%20principle" title="maximum principle">maximum principle</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Fourier%20heat%20conduction" title=" non-Fourier heat conduction"> non-Fourier heat conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20correction%20method" title=" residual correction method"> residual correction method</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-elastic%20response" title=" thermo-elastic response"> thermo-elastic response</a> </p> <a href="https://publications.waset.org/abstracts/30884/application-of-residual-correction-method-on-hyperbolic-thermoelastic-response-of-hollow-spherical-medium-in-rapid-transient-heat-conduction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30884.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">431</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"></span> Adomian’s Decomposition Method to Functionally Graded Thermoelastic Materials with Power Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdy%20M.%20Youssef">Hamdy M.

As the tube is heated slowly, an uncoupled solution procedure is adopted under free and radially constrained boundary conditions. The nonlinear heat conduction equation is solved by a finite element collocation procedure and the corresponding distributions of stress and strain are computed by shooting iterations. The computational model is verified in comparison to the analytical solution by shutting down the temperature dependency of physical properties. In the analysis, experimental data available in the literature is used to describe the coefficient of thermal expansion $\alpha$, the thermal conductivity $k$, the modulus of rigidity $G$, the yield strength $\sigma_{0}$, and the Poisson's ratio $\nu$ of Nickel. Results of the analysis are presented in comparison to those having constant physical properties. As a result of the calculations, the temperature dependency of the material properties should be taken into account at higher temperature ranges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelasticity" title="thermoelasticity">thermoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20tube" title=" long tube"> long tube</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature-dependent%20properties" title=" temperature-dependent properties"> temperature-dependent properties</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20heating" title=" internal heating"> internal heating</a> </p> <a href="https://publications.waset.org/abstracts/22226/thermoelastic-analysis-of-a-tube-subjected-to-internal-heating-with-temperature-dependent-material-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22226.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">616</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"></span> Buckling Behavior of FGM Plates Using a Simplified Shear Deformation Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Bouazza">Mokhtar Bouazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the simplified theory will be used to predict the thermoelastic buckling behavior of rectangular functionally graded plates.

After yielding, the behavior of the specimen suddenly changes, including the possibility of cracking or buckling. So, the accumulation of damage or type of fracture changes depending on this condition. As it is difficult to accurately detect yield points of the several stress concentration points in structural steel specimens, an effort has been made in this research work to develop a convenient technique using thermography (temperature-based detection) during tensile tests for the precise detection of yield point initiation. To verify the applicability of thermography camera, tests were conducted under different loading conditions and measuring the deformation by installing various strain gauges and monitoring the surface temperature with the help of a thermography camera. The yield point of specimens was estimated with the help of temperature dip, which occurs due to the thermoelastic effect during the plastic deformation. The scattering of the data has been checked by performing a repeatability analysis. The effects of temperature imperfection and light source have been checked by carrying out the tests at daytime as well as midnight and by calculating the signal to noise ratio (SNR) of the noised data from the infrared thermography camera, it can be concluded that the camera is independent of testing time and the presence of a visible light source. Furthermore, a fully coupled thermal-stress analysis has been performed by using Abaqus/Standard exact implementation technique to validate the temperature profiles obtained from the thermography camera and to check the feasibility of numerical simulation for the prediction of results extracted with the help of the thermographic technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=signal%20to%20noise%20ratio" title="signal to noise ratio">signal to noise ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelastic%20effect" title=" thermoelastic effect"> thermoelastic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=thermography" title=" thermography"> thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20point" title=" yield point"> yield point</a> </p> <a href="https://publications.waset.org/abstracts/151454/temperature-based-detection-of-initial-yielding-point-in-loading-of-tensile-specimens-made-of-structural-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151454.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">110</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"></span> Response Delay Model: Bridging the Gap in Urban Fire Disaster Response System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulaiman%20Yunus">Sulaiman Yunus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The need for modeling response to urban fire disaster cannot be over emphasized, as recurrent fire outbreaks have gutted most cities of the world. This necessitated the need for a prompt and efficient response system in order to mitigate the impact of the disaster. Promptness, as a function of time, is seen to be the fundamental determinant for efficiency of a response system and magnitude of a fire disaster. Delay, as a result of several factors, is one of the major determinants of promptgness of a response system and also the magnitude of a fire disaster. Response Delay Model (RDM) intends to bridge the gap in urban fire disaster response system through incorporating and synchronizing the delay moments in measuring the overall efficiency of a response system and determining the magnitude of a fire disaster. The model identified two delay moments (pre-notification and Intra-reflex sequence delay) that can be elastic and collectively plays a significant role in influencing the efficiency of a response system. Due to variation in the elasticity of the delay moments, the model provides for measuring the length of delays in order to arrive at a standard average delay moment for different parts of the world, putting into consideration geographic location, level of preparedness and awareness, technological advancement, socio-economic and environmental factors. It is recommended that participatory researches should be embarked on locally and globally to determine standard average delay moments within each phase of the system so as to enable determining the efficiency of response systems and predicting fire disaster magnitudes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delay%20moment" title="delay moment">delay moment</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20disaster" title=" fire disaster"> fire disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=reflex%20sequence" title=" reflex sequence"> reflex sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=response" title=" response"> response</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20delay%20moment" title=" response delay moment"> response delay moment</a> </p> <a href="https://publications.waset.org/abstracts/111201/response-delay-model-bridging-the-gap-in-urban-fire-disaster-response-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111201.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">213</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"></span> Response Reduction Factor for Earthquake Resistant Design of Special Moment Resisting Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohan%20V.%20Ambekar">Rohan V.

Calculation of response reduction factor (R) is done as per the new formulation of response reduction factor (R) given by Applied Technology Council (ATC)-19 which is the product of strength factor (Rs), ductility factor (Rµ) and redundancy factor (RR). The analysis revealed that these three factors affect the actual value of response reduction factor (R) and therefore they must be taken into consideration while determining the appropriate response reduction factor to be used during the seismic design process. The actual values required for determination of response reduction factor (R) is worked out on the basis of pushover curve which is a plot of base shear verses roof displacement. Finally, the calculated values of response reduction factor (R) of reinforced concrete special moment resisting frame (SMRF) with and without shear wall are compared with the codal values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=response%20reduction%20factor" title="response reduction factor">response reduction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20ratio" title=" ductility ratio"> ductility ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20shear" title=" base shear"> base shear</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20moment%20resisting%20frames" title=" special moment resisting frames"> special moment resisting frames</a> </p> <a href="https://publications.waset.org/abstracts/1362/response-reduction-factor-for-earthquake-resistant-design-of-special-moment-resisting-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1362.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">491</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"></span> Selection of Rayleigh Damping Coefficients for Seismic Response Analysis of Soil Layers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huai-Feng%20Wang">Huai-Feng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Meng-Lin%20Lou"> Meng-Lin Lou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ru-Lin%20Zhang"> Ru-Lin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One good analysis method in seismic response analysis is direct time integration, which widely adopts Rayleigh damping.

Compared with multivariate linear regression, functional linear regression is regarded as an infinite-dimensional case, and the main task is to reduce dimensions of functional response and functional predictors. One common approach is to adapt functional principal component analysis (FPCA) on functional predictors and then use a few leading functional principal components (FPC) to predict the functional model. The leading FPCs estimated by the typical FPCA explain a major variation of the functional predictor, but these leading FPCs may not be mostly correlated with the functional response, so they may not be significant in the prediction for response. In this paper, we propose a supervised functional principal component analysis method for a functional response model with FPCs obtained by considering the correlation of the functional response. Our method would have a better prediction accuracy than the typical FPCA method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supervised" title="supervised">supervised</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20principal%20component%20analysis" title=" functional principal component analysis"> functional principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20response" title=" functional response"> functional response</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20linear%20regression" title=" functional linear regression"> functional linear regression</a> </p> <a href="https://publications.waset.org/abstracts/177071/estimation-of-functional-response-model-by-supervised-functional-principal-component-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177071.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">82</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"></span> Quality Standards for Emergency Response: A Methodological Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20E.%20Lynette">Jennifer E.

This paper describes the techniques used to develop the initial framework and its potential application to professions under the broader field of emergency management. The example described in detail in this paper applies the framework specifically to fire response activities by firefighters. Within the quality standards framework, the fire response process is chronologically mapped. Individual variables within the sequence of events are identified. Through in-person data collection, questionnaires, interviews, and the expansion of the incident reporting system, this study identifies and categorizes previously unrecorded variables involved in the response phase of a fire. Following a data analysis of each variable using a quantitative or qualitative assessment, the variables are ranked pertaining to the magnitude of their impact to the event outcome. Among others, key indicators of quality performance in the analysis involve decision communication, resource utilization, response techniques, and response time. Through the application of this framework and subsequent utilization of quality standards indicators, there is potential to increase efficiency in the response phase of an emergency event; thereby saving additional lives, property, and resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20management" title="emergency management">emergency management</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20standards" title=" quality standards"> quality standards</a>, <a href="https://publications.waset.org/abstracts/search?q=response" title=" response"> response</a> </p> <a href="https://publications.waset.org/abstracts/47475/quality-standards-for-emergency-response-a-methodological-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47475.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">324</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"></span> Demand Response from Residential Air Conditioning Load Using a Programmable Communication Thermostat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saurabh%20Chanana">Saurabh Chanana</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Arora"> Monika Arora</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Demand response is getting increased attention these days due to the increase in electricity demand and introduction of renewable resources in the existing power grid. Traditionally demand response programs involve large industrial consumers but with technological advancement, demand response is being implemented for small residential and commercial consumers also. In this paper, demand response program aims to reduce the peak demand as well as overall energy consumption of the residential customers. Air conditioners are the major reason of peak load in residential sector in summer, so a dynamic model of air conditioning load with thermostat action has been considered for applying demand response programs. A programmable communicating thermostat (PCT) is a device that uses real time pricing (RTP) signals to control the thermostat setting. A new model incorporating PCT in air conditioning load has been proposed in this paper. Results show that introduction of PCT in air conditioner is useful in reducing the electricity payments of customers as well as reducing the peak demand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demand%20response" title="demand response">demand response</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20energy%20management" title=" home energy management"> home energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=programmable%20communicating%20thermostat" title=" programmable communicating thermostat"> programmable communicating thermostat</a>, <a href="https://publications.waset.org/abstracts/search?q=thermostatically%20controlled%20appliances" title=" thermostatically controlled appliances"> thermostatically controlled appliances</a> </p> <a href="https://publications.waset.org/abstracts/1662/demand-response-from-residential-air-conditioning-load-using-a-programmable-communication-thermostat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1662.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">614</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"></span> Acoustic Room Impulse Response Computation with Image Sources and Frequency Dependent Boundary Reflection Coefficients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratik%20Gandhi">Pratik Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kavitha%20Chandra"> Kavitha Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Thompson"> Charles Thompson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A computational model of the acoustic room impulse response between transmitters and receivers located in an enclosed cavity under the influence of frequency-dependent reflection coefficients of the walls is presented.

The results showed that the seismic response features of bridges crossing fault were different from the bridges in the near-fault region. The design according to the bridge in near-fault region would cause the calculation results with insecurity and non-reasonable if the effect of cross the fault was ignored. The design of seismic fortification should be based on seismic response feature, which could reduce the adverse effect caused by the structure damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20engineering" title="bridge engineering">bridge engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response%20feature" title=" seismic response feature"> seismic response feature</a>, <a href="https://publications.waset.org/abstracts/search?q=across%20faults" title=" across faults"> across faults</a>, <a href="https://publications.waset.org/abstracts/search?q=rupture%20directivity%20effect" title=" rupture directivity effect"> rupture directivity effect</a>, <a href="https://publications.waset.org/abstracts/search?q=fling%20step" title=" fling step"> fling step</a> </p> <a href="https://publications.waset.org/abstracts/19709/study-on-seismic-response-feature-of-multi-span-bridges-crossing-fault" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19709.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"></span> Stress Analysis of Laminated Cylinders Subject to the Thermomechanical Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eafak%20Aksoy">Şafak Aksoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kur%C5%9Fun"> Ali Kurşun</a>, <a href="https://publications.waset.org/abstracts/search?q=Erhan%20%C3%87etin"> Erhan Çetin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Re%C5%9Fit%20Habo%C4%9Flu"> Mustafa Reşit Haboğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, thermo elastic stress analysis is performed on a cylinder made of laminated isotropic materials under thermomechanical loads.

During the concentration measurement, the response time of detector is a very important parameter, especially for those fire-extinguishing systems with rapid gas dispersion. Long response time will not only underestimate its concentration but also prolong the change of concentration with time. Therefore it is necessary to analyze the factors influencing the response time. In the paper, an aspirating concentration detection method was introduced, which is achieved by using a small critical nozzle and a laminar flowmeter, and because of the response time is mainly related to the gas transport process from sampling site to the sensor, the effects of exhaust pipe size, gas flow rate, and gas concentration on its response time were analyzed. During the research, Bromotrifluoromethane (CBrF₃) was used. The effect of the sampling tube was investigated with different length of 1, 2, 3, 4 and 5 m (5mm in pipe diameter) and different pipe diameter of 3, 4, 5, 6 and 8 mm (3m in length). The effect of gas flow rate was analyzed by changing the throat diameter of the critical nozzle with 0.5, 0.682, 0.75, 0.8, 0.84 and 0.88 mm. The effect of gas concentration on response time was studied with the concentration range of 0-25%. The result showed that the response time increased with the increase of both the length and diameter of the sampling pipe, and the effect of length on response time was linear, but for the effect of diameter, it was exponential. It was also found that as the throat diameter of critical nozzle increased, the response time reduced a lot, in other words, gas flow rate has a great influence on response time. For the effect of gas concentration, the response time increased with the increase of the CBrF₃ concentration, and the slope of the curve was reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspirating%20concentration%20detection" title="aspirating concentration detection">aspirating concentration detection</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20extinguishing" title=" fire extinguishing"> fire extinguishing</a>, <a href="https://publications.waset.org/abstracts/search?q=gaseous%20agent" title=" gaseous agent"> gaseous agent</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20time" title=" response time"> response time</a> </p> <a href="https://publications.waset.org/abstracts/74810/analysis-of-factors-influencing-the-response-time-of-an-aspirating-gaseous-agent-concentration-detection-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74810.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">276</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"></span> Improved Estimation Strategies of Sensitive Characteristics Using Scrambled Response Techniques in Successive Sampling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Suman">S.

Current fire incident reports lack detailed information that can lead to breakthroughs in research and improve emergency response efforts. Information generated from the report database is analyzed and assessed for efficiency and quality. By utilizing information collection gaps in the incident reports, an improved, indepth, and streamlined quality gauging system is developed for use by fire brigades. This study pinpoints previously unrecorded factors involved in the response phases of a fire. Variables are recorded and ranked based on their influence to event outcome. By assessing and measuring these data points, quality standards are developed. These quality standards include details of the response phase previously overlooked which individually and cumulatively impact the overall success of a fire response effort. Through the application of this tool and implementation of associated quality standards at Denmark’s fire brigades, there is potential to increase efficiency and quality in the preparedness and response phases, thereby saving additional lives, property, and resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20management" title="emergency management">emergency management</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=preparedness" title=" preparedness"> preparedness</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20standards" title=" quality standards"> quality standards</a>, <a href="https://publications.waset.org/abstracts/search?q=response" title=" response"> response</a> </p> <a href="https://publications.waset.org/abstracts/38422/development-of-quality-assessment-tool-to-gauge-fire-response-activities-of-emergency-personnel-in-denmark" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38422.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">329</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"></span> Design of Real Time Early Response Systems for Natural Disaster Management Based on Automation and Control Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Pacheco">C.

Real Time Early Response Systems (RTERSs) incorporate real time information as feedback data for closing control loop and for generating real time situation assessment. A review of the state of the art works that fit the concept of RTERS is presented, and it is found that they are mainly focused on manmade disasters. At the same time, in response phase of natural disaster management many works are involved in creating early warning systems, but just few efforts have been put on deciding what to do once an alarm is activated. In this context a RTERS arises as a useful tool for supporting people in their decision making process during natural disasters after an event is detected, and also as an innovative context for applying well-known automation technologies and automatic control concepts and tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disaster%20management" title="disaster management">disaster management</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response%20system" title=" emergency response system"> emergency response system</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20disasters" title=" natural disasters"> natural disasters</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time" title=" real time"> real time</a> </p> <a href="https://publications.waset.org/abstracts/26120/design-of-real-time-early-response-systems-for-natural-disaster-management-based-on-automation-and-control-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26120.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">447</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"></span> Analysis of the Relationship between the Unitary Impulse Response for the nth-Volterra Kernel of a Duffing Oscillator System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guillermo%20Manuel%20Flores%20Figueroa">Guillermo Manuel Flores Figueroa</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Alejandro%20Vazquez%20Feijoo"> Juan Alejandro Vazquez Feijoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Navarro%20Antonio"> Jose Navarro Antonio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A continuous nonlinear system response may be obtained by an infinite sum of the so-called Volterra operators.
