It affects millions of workers throughout Europe, with a large-scale economic and social burden. These specific efforts have failed to produce significant results yet, probably due to the limited availability and high costs of occupational risk assessment at work, especially when the methods are complex, consume excessive resources or depend on self-evaluations and observations of poor accuracy. To overcome these limitations, a pervasive system of risk assessment tools in real time has been developed, which has the characteristics of a systematic approach, with good precision, usability and resource efficiency, essential to facilitate the prevention of musculoskeletal disorders in the long term. The system allows the combination of different wearable sensors, placed on different limbs, to be used for data collection and evaluation by a software solution, according to the needs and requirements in each individual working environment. This is done in a non-disruptive manner for both the occupational health expert and the workers. The creation of this solution allows us to attend different research activities that require, as an essential starting point, the recording of data with ergonomic value of very diverse origin, especially in real work environments. The software platform is here presented with a complimentary smart clothing system for data acquisition, comprised of a T-shirt containing inertial measurement units (IMU), a vest sensorized with textile electronics, a wireless electrocardiogram (ECG) and thoracic electrical bio-impedance (TEB) recorder and a glove sensorized with variable resistors, dependent on the angular position of the wrist. The collected data is processed in real-time through a mobile application software solution, implemented in commercially available Android-based smartphones and tablet platforms. Based on the collection of this information and its analysis, real-time risk assessment and feedback about postural improvement is possible, adapted to different contexts. The result is a tool which provides added value to ergonomists and occupational health agents, as in situ analysis of postural behavior can assist in a quantitative manner in the evaluation of work techniques and the occupational environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title="ergonomics">ergonomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20technologies" title=" mobile technologies"> mobile technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20textiles" title=" smart textiles"> smart textiles</a> </p> <a href="https://publications.waset.org/abstracts/92309/real-time-working-environment-risk-analysis-with-smart-textiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92309.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">117</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">70</span> The Philosophical Basis of Democracy: An Islamic Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahimeh%20Hooshyar">Fahimeh Hooshyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Mojtaba%20Abtahi"> Seyyed Mojtaba Abtahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Democracy which is, in its greek roots, consisted of “Demo” (People) and “Kratic” (people) is referring to governing of the people or governing by the people. in its widest definition it refers to a common lifestyle in which all the people has the equal potentials for social participating. But in political perspective, democracy is looking for the equal participation right of the citizens in political decision-making process. in this viewpoint, the democracy is solely a political construct or a social-political style in which all the values are relative. In this definition of the democracy emphasis is on equality of the people based on the governing rule and the natural social and political rights of every member of humankind. This notion of democracy by no means is a self reliant idea and the need of an ideological basis for approaching to this idea is inevitable. In this paper we are trying to define the inter-relations of democracy and its philosophical basis to Islamic fundamental ideas. Our approach to this topic would be a philosophical ideological one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islam" title="Islam">Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy%E2%80%99s%20philosophical%20basis" title=" democracy’s philosophical basis"> democracy’s philosophical basis</a>, <a href="https://publications.waset.org/abstracts/search?q=secularism" title=" secularism"> secularism</a>, <a href="https://publications.waset.org/abstracts/search?q=fundamentalism" title=" fundamentalism"> fundamentalism</a> </p> <a href="https://publications.waset.org/abstracts/19428/the-philosophical-basis-of-democracy-an-islamic-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19428.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">446</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">69</span> The Study of Solar Activity during Sun Eclipse and Its Relation to Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanieh%20Sadat%20Jannesari.%20Rahelehossadat%20Abtahi">Hanieh Sadat Jannesari.

So far, experts have tried to use precursors to identify the earthquake before it occurs in order to alert and save people, a part of which relates to solar activity and earthquakes. The purpose of this article is to investigate solar activity during the solar eclipse as a precursor to pre-earthquake awareness. Information from this article is derived from the Influences and USGS Daily Data Center. During solar activity, electric interactions between the solar wind and the celestial bodies are formed, and then gravitational lenses are formed. If, during this event, there is also an eclipse, the dispersed waves in space (in accordance with the theory of general relativity of Einstein) in contact with plasma-gravitational lenses in space will move in a straight line toward the earth. In addition to forming the focal point, these gravitational lenses reflect the source image either at their focal length or farther away. The image reflected in the earth by ionized particles in the form of energy transmission lines can cause material collapse and earthquakes. In this study, the correlation between solar winds and the celestial bodies during the solar eclipse is about 76% of the location of large earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma-gravitational%20lens" title=" plasma-gravitational lens"> plasma-gravitational lens</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20eclipse" title=" solar eclipse"> solar eclipse</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20spots" title=" solar spots"> solar spots</a> </p> <a href="https://publications.waset.org/abstracts/190332/the-study-of-solar-activity-during-sun-eclipse-and-its-relation-to-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190332.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">26</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">68</span> Challenges in E-Government: Conceptual Views and Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasim%20Alguliev">Rasim Alguliev</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Yusifov"> Farhad Yusifov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the international experience, conceptual and architectural principles of forming of electron government are researched and some suggestions were made.

The aim of this study is to determine the consumption of water and all other beverages in children (8-13 years) and adolescents (14-17 years) in Tehran metropolitan city of Iran. Materials and Methods: In this cross-sectional study, 455 children (8-13 years) and 334 adolescents (14-17 years) were retrieved from north, center, and south of Tehran (18 schools). Instrument for data collection consisted of a “demographic and general health” questionnaire and a “7-day fluid record”. Data analyses were performed with SPSS 16 software. Results: The mean total consumption of fluids in school children was 1302 ± 500.6 ml/day. The highest mean intakes were observed for water (666 ± 398 ml/day), followed by milk (239 ± 183 ml/day), regular soft beverages (RSB) (188 ± 148 ml/day), and juices (60 ± 74 ml/day). Water, hot drinks (mainly tea) and soft drinks intake was significantly more in boys than girls. A significantly lower intake of milk and a higher intake of RSB and hot beverages (mainly tea) have been seen among adolescents compared to children<span dir="RTL">.</span> Conclusion: The most important finding is that mean fluid intake of children and adolescents does not meet international adequate intake references for water and fluids. This finding may suggest the necessity of development of the local references. To improve fluid intake habits of children and adolescents, relevant policy making and actions are warranted<span dir="RTL">.</span> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescents" title="adolescents">adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=beverages" title=" beverages"> beverages</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a> </p> <a href="https://publications.waset.org/abstracts/82332/water-and-beverage-consumption-among-children-and-adolescents-in-tehran-metropolitan-city-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82332.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">174</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">66</span> The Effect of Measurement Distribution on System Identification and Detection of Behavior of Nonlinearities of Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Javad%20Mollakazemi">Mohammad Javad Mollakazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Asadi"> Farhad Asadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aref%20Ghafouri"> Aref Ghafouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we considered and applied parametric modeling for some experimental data of dynamical system.

Samali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Façade panels of various shapes, weights, and connections usually act as a barrier between the indoor and outdoor environments. They also play a major role in enhancing the aesthetics of building structures. They are attached by different types of connections to the primary structure or inner panels in double skin façade skins. Structural buildings designed to withstand seismic shocks have been undergoing a critical appraisal in recent years, with the emphasis changing from ‘strength’ to ‘performance’. Performance based design and analysis have found their way into research, development, and practice of earthquake engineering, particularly after the 1994 Northridge and 1995 Kobe earthquakes. The design performance of facades as non-structural elements has now focused mainly on evaluating the damage sustained by façade frames with fixed connections, not movable ones. This paper will review current design standards for structural buildings, including the performance of structural and non-structural components during earthquake excitations in order to overview and evaluate the damage assessment and behaviour of various façade systems in building structures during seismic activities. The proposed solutions for each facade system will be discussed case by case to evaluate their potential for incorporation with newly designed connections. Finally, Double-Skin-Facade systems can potentially be combined with movable facade technology, although other glazing systems would require minor to major changes in their design before being integrated into the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20performance" title="building performance">building performance</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20engineering" title=" earthquake engineering"> earthquake engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=glazing%20system" title=" glazing system"> glazing system</a>, <a href="https://publications.waset.org/abstracts/search?q=movable%20fa%C3%A7ade%20technology" title=" movable façade technology "> movable façade technology </a> </p> <a href="https://publications.waset.org/abstracts/22498/a-review-of-the-drawbacks-of-current-fixed-connection-facade-systems-non-structural-standards-and-ways-of-integrating-movable-facade-technology-into-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22498.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">548</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">62</span> A High Quality Factor Filter Based on Quasi- Periodic Photonic Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Alipour-Banaei">Hamed Alipour-Banaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Mehdizadeh"> Farhad Mehdizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report the design and characterization of ultra high quality factor filter based on one-dimensional photonic-crystal Thue-Morse sequence structure.

The blood clot helps you stop bleeding. Blood clots are made of a combination of blood cells, platelets(small sticky cells that speed up the clot-making process), and fibrin (protein that forms a thread-like mesh to trap cells). Doctors call this kind of blood clot a “thrombus.”We study the effects of different parameters on the deposition of Nanoparticles on the surface of a bump in the blood vessels by the magnetic field. The Maxwell and the flow equations are solved for this purpose. It is assumed that the blood is non-Newtonian and the number of particles has been considered enough to rely on the results statistically. Using MHD and its property it is possible to control the flow velocity, remove the fouling on the walls and return the system to its original form. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD" title="MHD">MHD</a>, <a href="https://publications.waset.org/abstracts/search?q=fouling" title=" fouling"> fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=in-vivo" title=" in-vivo"> in-vivo</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20clots" title=" blood clots"> blood clots</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/14099/simulation-of-remove-the-fouling-on-the-in-vivo-by-using-mhd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14099.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">469</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">59</span> From Linear to Nonlinear Deterrence: Deterrence for Rising Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Ghasemi">Farhad Ghasemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Along with transforming the international system into a complex and chaotic system, the fundamental question arises: how can deterrence be reconstructed conceptually and theoretically in this system model? The deterrence system is much more complex today than it was seven decades ago.

The author aims to improve this point by focusing on complexity and chaos theories, especially their nonlinearity and cascading failure principles. This article proposes that the perception of deterrence as a linear system is a fundamental mistake, as the new dynamics of the surrounding international system do not take into account.

To this end, a model is presented for ranking DMUs on the base of their superefficiency by considering the mentioned restrictions related to weights. This percentage can be determined by decision Maker. If the specific percentage is unsuitable, we can find a suitable and feasible one for ranking DMUs accordingly.

A physical examination and positive VZV polymerase chain reaction (PCR) of cerebrospinal fluid (CSF) suggested VZV encephalitis. Complication of VZV encephalitis is considered as the cause of blindness and deafness. In neurological deficit patient especially with a history of herpes zoster, VZV infection should be regarded as the responsible agent in inflammatory disorders of nervous system.

Nevertheless, various challenges threaten these ecosystems and disrupt their ecological character. Among these, the effects of human-based threats are more devastating. Following mass degradation of wetlands during 1970s, the Ramsar Convention on Wetlands (Ramsar, Iran, 1971) was concluded to conserve wetlands of international importance and prevent destruction and degradation of such ecosystems through wise use of wetlands as a mean to achieve sustainable development in all over the world. Therefore, in this paper, efforts have been made to analyze threats to wetlands and then investigate solutions in the framework of the Ramsar Convention. Finally, in order to operate these mechanisms, this study concludes that all states should in turn make their best effort to improve and restore global wetlands through preservation of environmental standards and close contribution and also through taking joint measures with other states effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramsar%20Convention" title="Ramsar Convention">Ramsar Convention</a>, <a href="https://publications.waset.org/abstracts/search?q=threats" title=" threats"> threats</a>, <a href="https://publications.waset.org/abstracts/search?q=wetland%20wcosystems" title=" wetland wcosystems"> wetland wcosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=wise%20use" title=" wise use"> wise use</a> </p> <a href="https://publications.waset.org/abstracts/6722/analytical-study-on-threats-to-wetland-ecosystems-and-their-solutions-in-the-framework-of-the-ramsar-convention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6722.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">401</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">53</span> Model Order Reduction for Frequency Response and Effect of Order of Method for Matching Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aref%20Ghafouri">Aref Ghafouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20javad%20Mollakazemi"> Mohammad javad Mollakazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Asadi"> Farhad Asadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, model order reduction method is used for approximation in linear and nonlinearity aspects in some experimental data.

The method is validated in simulation and influence of different autonomous and non-autonomous DS such as limit cycles, and unstable DS on this algorithm and also the position of different obstacles in complex environment is explained.

In this respect, a large database consisting of 1157 records occurring within the Iranian Plateau with moment magnitudes of greater than or equal to 5 and Joyner-Boore distances up to 200 km has been considered. Geometric averages of horizontal peak ground accelerations (PGA) as well as 5% damped linear elastic response spectral accelerations (SA) at periods of 0.2, 0.5, 1.0, and 2.0 sec are used as strong motion parameters. The initial database is divided into two different datasets, for Northern Iran (NI) and Central and Southern Iran (CSI). The comparison between strong ground motions of these two regions reveals that there is no evidence for significant differences; therefore, data from these two regions may be combined to estimate the unknown coefficients of attenuation relationships. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title="ANOVA">ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=attenuation%20relationships" title=" attenuation relationships"> attenuation relationships</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20Plateau" title=" Iranian Plateau"> Iranian Plateau</a>, <a href="https://publications.waset.org/abstracts/search?q=PGA" title=" PGA"> PGA</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20variation" title=" regional variation"> regional variation</a>, <a href="https://publications.waset.org/abstracts/search?q=SA" title=" SA"> SA</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20ground%20motion" title=" strong ground motion"> strong ground motion</a> </p> <a href="https://publications.waset.org/abstracts/43832/investigation-of-regional-differences-in-strong-ground-motions-for-the-iranian-plateau" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43832.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">314</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">49</span> The Experimental Investigation of Temperature Influence on the Oscillations of Particles on Liquid Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sathish%20K.%20Gurupatham">Sathish K.

This happens due to the combined effect of the capillary force, buoyant weight of the particle and the viscous drag that the particle experiences in the liquid. The particle undergoes oscillations normal to the interface before it comes to rest on the interface. These oscillations, in turn, induce a flow on the interface which disperses the particles radially outward. This phenomenon has a significant role in the pollination of sea plants such as Ruppia in which the formation of ‘pollen rafts’ is the first step. This paper investigates, experimentally, the influence of the temperature of the liquid on which this dispersion occurs. It was observed that the frequency of oscillations of the particles decreased with the increase in the temperature of the liquid. It is because the magnitude of capillary force also decreased when the temperature of the liquid increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20dispersion" title="particle dispersion">particle dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20force" title=" capillary force"> capillary force</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20drag" title=" viscous drag"> viscous drag</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillations" title=" oscillations"> oscillations</a> </p> <a href="https://publications.waset.org/abstracts/62666/the-experimental-investigation-of-temperature-influence-on-the-oscillations-of-particles-on-liquid-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62666.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">372</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">48</span> Real Time Activity Recognition Framework for Health Monitoring Support in Home Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaikh%20Farhad%20Hossain">Shaikh Farhad Hossain</a>, <a href="https://publications.waset.org/abstracts/search?q=Liakot%20Ali"> Liakot Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technology advances accelerate the quality and type of services provided for health care and especially for monitoring health conditions.

The proposed antenna has a compact dimension of 30 x 25 x 1.6 mm3 and achieves an overall bandwidth (S11<-10dB) is 5.8 GHz from 2.7 GHz to 8.5 GHz. The antenna attains more than 4 dBi realized the gain and 80% efficiency over the bandwidth with omnidirectional radiation pattern. The design and simulation of the proposed antenna are performed in Computer Simulation Technology (CST) Microwave Studio.

The effect of adding the nanoparticle to base fluid and Richardson number on the heat transfer enhancement is investigated as Richardson number increases from 0.1 to 0.7. The experimental results demonstrate that the combined forced-natural convection heat transfer rate may be improved significantly with an increment of mass nanoparticle concentration from 0% to 1.5%. In this experiment, a correlation is also proposed to predict the mixed convection heat transfer rate of CuO-HTO nanofluid flow. The maximum deviation of both correlations is less than 14%.
