Studying the structural breaks in the time-dependent Correlation matrix associated with a collection had been a subject of interest for a better understanding of the market movements, portfolio selection, etc. The current paper proposes a methodology for testing the change in the time-dependent correlation structure of a portfolio in the high dimensional data using the techniques of generalized inverse, singular valued decomposition and multivariate distribution theory which has not been addressed so far. The asymptotic properties of the proposed test are derived. Also, the performance and the validity of the method is tested on a real data set.

We present a method designed for detecting changes in the covariance structure of high-dimensional time series data, where the number of variables closely matches the data length. Our objective is to achieve unbiased test statistic estimation under the null hypothesis. We delve into the utilization of Random Matrix Theory to analyze the behavior of our test statistic within a high-dimensional context.

Flooding presents one of the more serious threats to this safety, putting a larger number of people in harm’s way in congested urban settings. Climate change is adding to this stress by creating a dichotomy in the urban flood response. On the one hand, climate change is causing storms to intensify, resulting in more destructive, rarer floods, while on the other hand, longer dry periods are decreasing the severity of more frequent, less intense floods. This variability is creating a need to be more agile and innovative in how we design for and manage urban flooding. Here, we argue that to cope with this challenge climate change brings, we need to move towards urban flood management through resilience rather than flood prevention. We also argue that dealing with the larger variation in flood response to climate change means that we need to look at flooding from all aspects rather than the single-dimensional focus of flood depths and extents. In essence, we need to rethink how we manage flooding in the urban space. This change in our thought process and approach to flood management requires a practical way to assess and quantify resilience that is built into the urban landscape so that informed decision-making can support the required changes in planning and infrastructure design. Towards that end, we propose a Simple Urban Flood Resilience Index (SUFRI) based on a robust definition of resilience as a tool to assess flood resilience. The application of a simple resilience index such as the SUFRI can provide a practical tool that considers urban flood management in a multi-dimensional way and can present solutions that were not previously considered. When such an index is grounded on a clear and relevant definition of resilience, it can be a reliable and defensible way to assess and assist the process of adapting to the increasing challenges in urban flood management with climate change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20flood%20resilience" title="urban flood resilience">urban flood resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20management" title=" flood management"> flood management</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20modelling" title=" flood modelling"> flood modelling</a> </p> <a href="https://publications.waset.org/abstracts/182887/climate-change-and-urban-flooding-the-need-to-rethinking-urban-flood-management-through-resilience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182887.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">49</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">8980</span> The Effect of Change Communication towards Commitment to Change through the Role of Organizational Trust</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enno%20R.%20Farahzehan">Enno R.

Organizational changes were also made to defend the existence of the organization itself. Success in implementing organizational change consists of a variety of factors, one of which is individual (employee) who run changes. The employee must have the willingness and ability in carrying out the changes. Besides, employees must also have a commitment to change for creation of the successful organizational change. This study aims to execute the effect of change communication towards commitment to change through the role of organizational trust. The respondents of this study were employees who work in organizations, which have been or are currently running organizational changes. The data were collected using Change Communication, Commitment to Change, and Organizational Trust Inventory. The data were analyzed using regression. The result showed that there is an effect among change communication towards commitment to change which is higher when mediated by organizational trust. This paper will contribute to the knowledge and implications of organizational change, that shows change communication can affect commitment to change among employee if there is trust in the organization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=change%20communication" title="change communication">change communication</a>, <a href="https://publications.waset.org/abstracts/search?q=commitment%20to%20change" title=" commitment to change"> commitment to change</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20trust" title=" organizational trust"> organizational trust</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20change" title=" organizational change"> organizational change</a> </p> <a href="https://publications.waset.org/abstracts/69139/the-effect-of-change-communication-towards-commitment-to-change-through-the-role-of-organizational-trust" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69139.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">342</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">8979</span> Spatial Rank-Based High-Dimensional Monitoring through Random Projection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Zhang">Chen Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nan%20Chen"> Nan Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-dimensional process monitoring becomes increasingly important in many application domains, where usually the process distribution is unknown and much more complicated than the normal distribution, and the between-stream correlation can not be neglected. However, since the process dimension is generally much bigger than the reference sample size, most traditional nonparametric multivariate control charts fail in high-dimensional cases due to the curse of dimensionality. Furthermore, when the process goes out of control, the influenced variables are quite sparse compared with the whole dimension, which increases the detection difficulty. Targeting at these issues, this paper proposes a new nonparametric monitoring scheme for high-dimensional processes. This scheme first projects the high-dimensional process into several subprocesses using random projections for dimension reduction. Then, for every subprocess with the dimension much smaller than the reference sample size, a local nonparametric control chart is constructed based on the spatial rank test to detect changes in this subprocess. Finally, the results of all the local charts are fused together for decision. Furthermore, after an out-of-control (OC) alarm is triggered, a diagnostic framework is proposed. using the square-root LASSO. Numerical studies demonstrate that the chart has satisfactory detection power for sparse OC changes and robust performance for non-normally distributed data, The diagnostic framework is also effective to identify truly changed variables. Finally, a real-data example is presented to demonstrate the application of the proposed method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=random%20projection" title="random projection">random projection</a>, <a href="https://publications.waset.org/abstracts/search?q=high-dimensional%20process%20control" title=" high-dimensional process control"> high-dimensional process control</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20rank" title=" spatial rank"> spatial rank</a>, <a href="https://publications.waset.org/abstracts/search?q=sequential%20change%20detection" title=" sequential change detection"> sequential change detection</a> </p> <a href="https://publications.waset.org/abstracts/62697/spatial-rank-based-high-dimensional-monitoring-through-random-projection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62697.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">299</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">8978</span> Framework for Developing Change Team to Maximize Change Initiative Success</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Z.%20Ansari">Mohammad Z.

The application of change facilitators can be seen in various change models; Lewin, Lippitt, etc. The facilitators within numerous change models are considered as internal/external consultants. Whilst most of the scholarly paper considers change facilitation as a consensus attempt to improve organization, there is a lack of a framework that develops both the organization and the change facilitator creating a self-sustaining change environment. This research paper introduces the development of the framework for change Leaders, Planners, and Executers (LPE), aiming at various organizational levels (Process, Departmental, and Organisational). The LPE framework is derived by exploring interrelated characteristics between facilitator(s) and the organization through qualitative research for understanding change management techniques and facilitator(s) behavioral aspect from existing Change Management models and Organisation behavior works of literature. The introduced framework assists in highlighting and identify the most appropriate change team to successfully deliver the change initiative within any organization (s). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=change%20initiative" title="change initiative">change initiative</a>, <a href="https://publications.waset.org/abstracts/search?q=LPE%20framework" title=" LPE framework"> LPE framework</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20facilitator%28s%29" title=" change facilitator(s)"> change facilitator(s)</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20change" title=" sustainable change"> sustainable change</a> </p> <a href="https://publications.waset.org/abstracts/126523/framework-for-developing-change-team-to-maximize-change-initiative-success" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8977</span> Enhancement of Thermal Performance of Latent Heat Solar Storage System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rishindra%20M.%20Sarviya">Rishindra M.

It is also shown how distortion in space caused by the dynamics of four-dimensional bodies counterbalances the effect of expansion. We find that the motion of four-dimensional bodies through four-dimensional space leads to gravitational attraction, and the expansion of bodies leads to surface gravity.

However, organizational change is not easy to implement and is prone to failure. One of the reasons of change failure is due to lack of employees’ commitment to change. There are many variables that can influence employees’ commitment to change. The influencing factors can be sourced from the organization or individuals themselves. This study focuses on the affective form of commitment to change. The objective of this study is to identify the effect of transformational leadership (organizational factor) and employees’ change self-efficacy (individual factor) on affective commitment to change. The respondents of this study were employees who work in organizations that are or have faced organizational change. The data were collected using Affective Commitment to Change, Change Self-Efficacy, and Transformational Leadership Inventory. The data were analyzed using regression. The result showed that both transformational leadership and change self-efficacy have a positive and significant impact on affective commitment to change. The implication of the study can be used for practitioners to enhance the success of organizational change, by developing transformational leadership on the leaders and change self-efficacy on the employees in order to create a high affective commitment to change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affective%20commitment%20to%20change" title="affective commitment to change">affective commitment to change</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20self-efficacy" title=" change self-efficacy"> change self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20change" title=" organizational change"> organizational change</a>, <a href="https://publications.waset.org/abstracts/search?q=transformational%20leadership" title=" transformational leadership"> transformational leadership</a> </p> <a href="https://publications.waset.org/abstracts/69121/the-effect-of-transformational-leadership-and-change-self-efficacy-on-employees-commitment-to-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69121.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">384</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">8974</span> Shrinkage Evaluation in a Stepped Wax Pattern – a Simulation Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20S%20Chauhan">Alok S Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20S."> Sridhar S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradyumna%20R."> Pradyumna R.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the process of precision investment casting of turbine hollow blade/vane components, a part of the dimensional deviations observed in the castings can be attributed to the wax pattern. In the process of injection moulding of wax to produce patterns, heated wax shrinks in size during cooling in the die, leading to a reduction in the dimensions of the pattern. Also, flow and thermal induced residual stresses result in shrinkage & warpage of the component after removal from the die, further adding to the deviations. Injection moulding parameters such as wax temperature, flow rate, packing pressure, etc. affect the flow and thermal behavior of the component and hence are directly responsible for the dimensional deviations. There is a need to precisely determine and control these deviations in order to achieve stringent dimensional accuracies imposed on these castings by aerospace standards. Simulation based approaches provide a platform to predict these dimensional deviations without resorting to elaborate experimentation. In the present paper, Moldex3D simulation package has been utilized to analyze the effect of variations in injection temperature, packing pressure and cooling time on the shrinkage behavior of a stepped pattern. Two types of waxes with different rheological properties have been included in the study to gauge the effect of change in wax on the dimensional deviations. A full factorial design of experiments has been configured with these parameters and results of analysis of variance have been presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wax%20patterns" title="wax patterns">wax patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20casting" title=" investment casting"> investment casting</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20die%2Fmould" title=" pattern die/mould"> pattern die/mould</a>, <a href="https://publications.waset.org/abstracts/search?q=wax%20injection" title=" wax injection"> wax injection</a>, <a href="https://publications.waset.org/abstracts/search?q=Moldex3D%20simulation" title=" Moldex3D simulation"> Moldex3D simulation</a> </p> <a href="https://publications.waset.org/abstracts/19217/shrinkage-evaluation-in-a-stepped-wax-pattern-a-simulation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19217.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">373</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">8973</span> Stochastic Richelieu River Flood Modeling and Comparison of Flood Propagation Models: WMS (1D) and SRH (2D)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Safrai">Maryam Safrai</a>, <a href="https://publications.waset.org/abstracts/search?q=Tewfik%20Mahdi"> Tewfik Mahdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents the stochastic modeling of the Richelieu River flood in Quebec, Canada, occurred in the spring of 2011. With the aid of the one-dimensional Watershed Modeling System (WMS (v.10.1) and HEC-RAS (v.4.1) as a flood simulator, the delineation of the probabilistic flooded areas was considered. Based on the Monte Carlo method, WMS (v.10.1) delineated the probabilistic flooded areas with corresponding occurrence percentages. Furthermore, results of this one-dimensional model were compared with the results of two-dimensional model (SRH-2D) for the evaluation of efficiency and precision of each applied model. Based on this comparison, computational process in two-dimensional model is longer and more complicated versus brief one-dimensional one. Although, two-dimensional models are more accurate than one-dimensional method, but according to existing modellers, delineation of probabilistic flooded areas based on Monte Carlo method is achievable via one-dimensional modeler. The applied software in this case study greatly responded to verify the research objectives. As a result, flood risk maps of the Richelieu River with the two applied models (1d, 2d) could elucidate the flood risk factors in hydrological, hydraulic, and managerial terms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flood%20modeling" title="flood modeling">flood modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=HEC-RAS" title=" HEC-RAS"> HEC-RAS</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20comparison" title=" model comparison"> model comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20flooded%20area" title=" probabilistic flooded area"> probabilistic flooded area</a>, <a href="https://publications.waset.org/abstracts/search?q=SRH-2D" title=" SRH-2D"> SRH-2D</a>, <a href="https://publications.waset.org/abstracts/search?q=WMS" title=" WMS"> WMS</a> </p> <a href="https://publications.waset.org/abstracts/107620/stochastic-richelieu-river-flood-modeling-and-comparison-of-flood-propagation-models-wms-1d-and-srh-2d" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107620.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">140</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">8972</span> The Effect of Psychological Capital and Psychological Empowerment on Employees' Commitment to Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muthmainah%20Mufidah">Muthmainah Mufidah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wustari%20L.%20H.%20Mangundjaya"> Wustari L.

The three-dimensional visualization geological modeling of mine is the digital characterization of mineral deposits and is one of the key technology of digital mining. Three-dimensional geological modeling is a technology that combines geological spatial information management, geological interpretation, geological spatial analysis and prediction, geostatistical analysis, entity content analysis and graphic visualization in a three-dimensional environment with computer technology and is used in geological analysis. In this paper, the three-dimensional geological modeling of an iron mine through the use of Surpac is constructed, and the weight difference of the estimation methods between the distance power inverse ratio method and ordinary kriging is studied, and the ore body volume and reserves are simulated and calculated by using these two methods. Compared with the actual mine reserves, its result is relatively accurate, so it provides scientific bases for mine resource assessment, reserve calculation, mining design and so on. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20geological%20modeling" title="three-dimensional geological modeling">three-dimensional geological modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=geological%20database" title=" geological database"> geological database</a>, <a href="https://publications.waset.org/abstracts/search?q=geostatistics" title=" geostatistics"> geostatistics</a>, <a href="https://publications.waset.org/abstracts/search?q=block%20model" title=" block model"> block model</a> </p> <a href="https://publications.waset.org/abstracts/167349/research-of-the-three-dimensional-visualization-geological-modeling-of-mine-based-on-surpac" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167349.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">78</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">8966</span> Multi-Dimensional Energy Resource Evaluation in Climate Change beyond the 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Alshammari">Hameed Alshammari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The decarbonisation of the energy sector beyond the 21ˢᵗ century is akin to establishing morally responsible mechanisms that can propagate sustainable livelihoods (Denina et al., 2021). It implies that Kuwait undertakes a re-evaluation of energy generation gaps so as to tap the potential to reduce overreliance on fossil fuel (Si et al., 2020) and align with global views on sustainable energy generation and consumption.(Herrero, Pineda, Villar, & Zambrano, 2020). Without the economic pressure to switch to alternative sources of energy, Kuwait requires a multi-dimensional analysis the energy policies andsources of energy other than fossil fuels (Alsaad, 2021).Currently, Kuwait has an energy system that is highly skewed towards fossil fuels (Alsaad, 2021); hence, the reliance on burning fossil fuels forms part of the core elements of the general inefficient energy systems that have negative consequences to global environmental and economic systems (Kang et al., 2020). This paper undertakes a detailed literature review on factors needed for the development of a framework for the multi-dimensional energy resource analysis in Kuwait. The framework aims aligning the current energy policies in Kuwait with the global decarbonisation drive, to promote sustainable energy strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decarbonisation" title="decarbonisation">decarbonisation</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=fossil%20fuels" title=" fossil fuels"> fossil fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-dimensional%20analysis" title=" multi-dimensional analysis"> multi-dimensional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/149672/multi-dimensional-energy-resource-evaluation-in-climate-change-beyond-the-21st-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149672.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">86</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">8965</span> Non-Isothermal Stationary Laminar Oil Flow Numerical Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniyar%20Bossinov">Daniyar Bossinov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers a non-isothermal stationary waxy crude oil flow in a two-dimensional axisymmetric pipe with the transition of a Newtonian fluid to a non-Newtonian fluid. The viscosity and yield stress of waxy crude oil are highly dependent on temperature changes. During the hot pumping of waxy crude oil through a buried pipeline, a non-isothermal flow occurs due to heat transfer to the surrounding soil. This leads to a decrease in flow temperature, an increase in viscosity, the appearance of yield stress, the crystallization of wax, and the deposition of solid particles on the pipeline's inner wall. The deposition of oil solid particles reduces a pipeline flow area and leads to the appearance of a stagnant zone with thermal insulation in the near-wall area. Waxy crude oil properties change. A Newtonian fluid at low temperatures transits to a non-Newtonian fluid. The one-dimensional modeling of a non-isothermal waxy crude oil flow in a two-dimensional axisymmetric pipeline by traditional averaging of temperature and velocity over the pipeline cross-section does not allow for explaining a physics phenomenon. Therefore, in this work, a two-dimensional flow model and the heat transfer of waxy oil are constructed. The calculated data show the transition of a Newtonian fluid to a non-Newtonian fluid due to the heat exchange of waxy oil with the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-isothermal%20laminar%20flow" title="non-isothermal laminar flow">non-isothermal laminar flow</a>, <a href="https://publications.waset.org/abstracts/search?q=waxy%20crude%20oil" title=" waxy crude oil"> waxy crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=stagnant%20zone" title=" stagnant zone"> stagnant zone</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20stress" title=" yield stress"> yield stress</a> </p> <a href="https://publications.waset.org/abstracts/188992/non-isothermal-stationary-laminar-oil-flow-numerical-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188992.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">27</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">8964</span> A Study Regarding Nanotechnologies as a Vector of New European Business Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Radan%20Ungureanu">Adriana Radan Ungureanu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The industrial landscape is changing due to the financial crises, poor availability of raw materials, new discoveries and interdisciplinary collaborations. New ideas shape the change through technologies and bring responses for a better life. The process of change is leaded by big players like states and companies, but they cannot keep their places on the market without the help of the small ones. The main tool of change is technology and the entire developed world dedicated efforts for decades in this direction. Even the expectations are not yet met, the research for finding adequate solutions is far from to be stopped. A relevant example is nanotechnology where most of discoveries still remain into laboratory and could not succeed to find the right way to the market. In front of this situation the right question could be: ”Is it worth investing in nanotechnology in the name of an uncertain future but with very little impact on present?” This paper tries to find a positive answer from a three-dimensional approach using a descriptive analyse based on available database supplied by the European case studies, reports, and literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Europe" title="Europe">Europe</a>, <a href="https://publications.waset.org/abstracts/search?q=KET%E2%80%99s" title=" KET’s"> KET’s</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/22794/a-study-regarding-nanotechnologies-as-a-vector-of-new-european-business-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22794.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">417</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">8963</span> Numerical Analysis of the Melting of Nano-Enhanced Phase Change Material in a Rectangular Latent Heat Storage Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radouane%20Elbahjaoui">Radouane Elbahjaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20El%20Qarnia"> Hamid El Qarnia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Melting of Paraffin Wax (P116) dispersed with Al<sub>2</sub>O<sub>3 </sub>nanoparticles in a rectangular latent heat storage unit (LHSU) is numerically investigated.

In this study, the Mach-Zehnder Interferometry method is applied to measure the temperature field of premixed air/landfill gas (LFG60:60% CH4+40% CO2) laminar flame. The three-dimensional flame of cylindrical slot burner can assume to be two-dimensional due to the high aspect ratio (L/W=10) of the rectangular slot. So, the method converts two-dimensional flame to closed isothermal curves called fringes and the outer fringes temperature is measured by thermocouples. The experiments are carried out for Reynolds numbers and equivalence ratios ranging from 100 to 400 and 1.0 to 1.4, respectively. Results show that by increasing the equivalence ratio or Reynolds number, the flame height increases. The maximum flame temperature decreases by increasing the equivalence ratio but does not change considerably by changing the Reynolds number. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landfill%20gas" title="landfill gas">landfill gas</a>, <a href="https://publications.waset.org/abstracts/search?q=Mach-Zehender%20interferometry" title=" Mach-Zehender interferometry"> Mach-Zehender interferometry</a>, <a href="https://publications.waset.org/abstracts/search?q=premix%20flame" title=" premix flame"> premix flame</a>, <a href="https://publications.waset.org/abstracts/search?q=slot%20burner" title=" slot burner"> slot burner</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20filed" title=" temperature filed "> temperature filed </a> </p> <a href="https://publications.waset.org/abstracts/126018/temperature-field-measurement-of-premixed-landfill-gas-laminar-flame-in-a-cylindrical-slot-burner-using-mach-zehnder-interferometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126018.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">150</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">8961</span> The Role of Psychological Hardiness and Psychological Resilience Employee's Commitment to Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ni%20Made%20Dian%20Swandewi">Ni Made Dian Swandewi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wustari%20L.%20Mangundjaya"> Wustari L.

Various techniques and technologies have been developed to improve the retrieval success rate. This study aimed to compare the effectiveness of a Dynamic Navigation System (DNS) and a three-dimensional microscope in retrieving broken rotary NiTi files when using trepan burs and the extractor system. Materials and Methods: Thirty maxillary first bicuspids with sixty separate roots were split into two comparable groups based on a comprehensive Cone-Beam Computed Tomography (CBCT) analysis of the root length and curvature. After standardised access opening, glide paths, and patency attainment with the K file (sizes 10 and 15), the teeth were arranged on 3D models (three per quadrant, six per model). Subsequently, controlled-memory heat-treated NiTi rotary files (#25/0.04) were notched 4 mm from the tips and fractured at the apical third of the roots. The C-FR1 Endo file removal system was employed under both guidance to retrieve the fragments, and the success rate, canal aberration, treatment time and volumetric changes were measured. The statistical analysis was performed using IBM SPSS software at a significance level of 0.05. Results: The microscope-guided group had a higher success rate than the DNS guidance, but the difference was insignificant (p > 0.05). In addition, the microscope-guided drills resulted in a substantially lower proportion of canal aberration, required less time to retrieve the fragments and caused a minor change in the root canal volume (p < 0.05). Conclusion: Although dynamically guided trephining with the extractor can retrieve separated instruments, it is inferior to three-dimensional microscope guidance regarding treatment time, procedural errors, and volume change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20navigation%20system" title="dynamic navigation
