It is a review paper which gives the idea of the trends in the construction project management and various models adopted for the betterment of the project planning and execution. Traditional scheduling and progress control techniques such as bar charts and the critical path method fail to provide information pertaining to the spatial aspects of a construction project. An integrated system was developed to represent construction progress not only in terms of a CPM schedule but also in terms of a graphical representation of the construction that is synchronized with the work schedule. Hence, it is suggested to work on the common platform from where all the data can be shared and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GIS" title="GIS">GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20management" title=" project management"> project management</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20model" title=" integrated model"> integrated model</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20project" title=" infrastructure project"> infrastructure project</a> </p> <a href="https://publications.waset.org/abstracts/19143/gis-based-project-management-information-system-for-infrastructure-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19143.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">519</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">95</span> Application of Grasshopper Optimization Algorithm for Design and Development of Net Zero Energy Residential Building in Ahmedabad, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sarkar">Debasis Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to apply the Grasshopper-Optimization-Algorithm (GOA) for designing and developing a Net-Zero-Energy residential building for a mega-city like Ahmedabad in India. The methodology implemented includes advanced tools like Revit for model creation and MATLAB for simulation, enabling the optimization of the building design. GOA has been applied in reducing cooling loads and overall energy consumption through optimized passive design features. For the attainment of a net zero energy mission, solar panels were installed on the roof of the building. It has been observed that the energy consumption of 8490 kWh was supported by the installed solar panels. Thereby only 840kWh had to be supported by non-renewable energy sources. The energy consumption was further reduced through the application of simulation and optimization methods like GOA, which further reduced the energy consumption to about 37.56 kWh per month from April to July when energy demand was at its peak. This endeavor aimed to achieve near-zero-energy consumption, showcasing the potential of renewable energy integration in building sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grasshopper%20optimization%20algorithm" title="grasshopper optimization algorithm">grasshopper optimization algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20zero%20energy" title=" net zero energy"> net zero energy</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20building" title=" residential building"> residential building</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title=" sustainable design"> sustainable design</a> </p> <a href="https://publications.waset.org/abstracts/188220/application-of-grasshopper-optimization-algorithm-for-design-and-development-of-net-zero-energy-residential-building-in-ahmedabad-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188220.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">39</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">94</span> Risk Based Building Information Modeling (BIM) for Urban Infrastructure Transportation Project </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sarkar">Debasis Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building Information Modeling (BIM) is a holistic documentation process for operational visualization, design coordination, estimation and project scheduling. BIM software defines objects parametrically and it is a tool for virtual reality. Primary advantage of implementing BIM is the visual coordination of the building structure and systems such as Mechanical, Electrical and Plumbing (MEP) and it also identifies the possible conflicts between the building systems. This paper is an attempt to develop a risk based BIM model which would highlight the primary advantages of application of BIM pertaining to urban infrastructure transportation project. It has been observed that about 40% of the Architecture, Engineering and Construction (AEC) companies use BIM but primarily for their outsourced projects. Also, 65% of the respondents agree that BIM would be used quiet strongly for future construction projects in India. The 3D models developed with Revit 2015 software would reduce co-ordination problems amongst the architects, structural engineers, contractors and building service providers (MEP). Integration of risk management along with BIM would provide enhanced co-ordination, collaboration and high probability of successful completion of the complex infrastructure transportation project within stipulated time and cost frame. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling%20%28BIM%29" title="building information modeling (BIM)">building information modeling (BIM)</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20transportation" title=" infrastructure transportation"> infrastructure transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20risk%20management" title=" project risk management"> project risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20metro%20rail" title=" underground metro rail"> underground metro rail</a> </p> <a href="https://publications.waset.org/abstracts/46712/risk-based-building-information-modeling-bim-for-urban-infrastructure-transportation-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46712.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">310</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">93</span> Critical Success Factors for Sustainable Smart City Project in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sarkar">Debasis Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Development of a Smart City would depend upon the development of its infrastructure in a smart way. Primarily based on the ideology of the fourth industrial revolution a Smart City project should have Smart governance, smart health care, smart building, smart transportation, smart mobility, smart energy, smart technology and smart citizen. Considering the Indian scenario of current state of cities in India, it has become very essential to decide the specific parameters which would govern the development of a Smart City project. It has been observed that there are significant parameters beyond Information and Communication Technology (ICT), which govern the development of a Smart City project. This paper is an attempt to identify the Critical Success Factors (CSF) which are significantly responsible for the development of a Smart City project in Western India. Responses to questionnaire survey were analyzed on basis of Likert scale. They were further critically evaluated with help of Factor Comparison Method (FCM) and Analytical Hierarchy Process (AHP). The project authorities need to incorporate Building Information Modeling (BIM) to make the smart city project more collaborative. To make the project more sustainable, use of flyash in the concrete used, reduced usage of cement and steel, use of alternate fuels like biodiesel is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchical%20process" title="analytical hierarchical process">analytical hierarchical process</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling" title=" building information modeling"> building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20success%20factors" title=" critical success factors"> critical success factors</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20comparison%20method" title=" factor comparison method"> factor comparison method</a> </p> <a href="https://publications.waset.org/abstracts/73243/critical-success-factors-for-sustainable-smart-city-project-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73243.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">252</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">92</span> Integrated Clean Development Mechanism and Risk Management Approach for Infrastructure Transportation Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sarkar">Debasis Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Clean development mechanism (CDM) can act as an effective instrument for mitigating climate change. This mechanism can effectively reduce the emission of CO2 and other green house gases (GHG). Construction of a mega infrastructure project like underground corridor construction for metro rail operation involves in consumption of substantial quantity of concrete which consumes huge quantity of energy consuming materials like cement and steel. This paper is an attempt to develop an integrated clean development mechanism and risk management approach for sustainable development for an underground corridor metro rail project in India during its construction phase. It was observed that about 35% reduction in CO2 emission can be obtained by adding fly ash as a part replacement of cement. The reduced emission quantity of CO2 which is of the quantum of about 21,646.36 MT would result in cost savings of approximately INR 8.5 million (USD 1,29,878).But construction and operation of such infrastructure projects of the present era are subject to huge risks and uncertainties throughout all the phases of the project, thus reducing the probability of successful completion of the project within stipulated time and cost frame. Thus, an integrated approach of combining CDM with risk management would enable the metro rail authorities to develop a sustainable risk mitigation measure framework to ensure more cost and energy savings and lesser time and cost over-run. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clean%20development%20mechanism%20%28CDM%29" title="clean development mechanism (CDM)">clean development mechanism (CDM)</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20transportation" title=" infrastructure transportation"> infrastructure transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20risk%20management" title=" project risk management"> project risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20metro%20rail" title=" underground metro rail "> underground metro rail </a> </p> <a href="https://publications.waset.org/abstracts/24661/integrated-clean-development-mechanism-and-risk-management-approach-for-infrastructure-transportation-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24661.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">475</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">91</span> Integrated Mass Rapid Transit System for Smart City Project in Western India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sarkar">Debasis Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jatan%20Talati"> Jatan Talati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is an attempt to develop an Integrated Mass Rapid Transit System (MRTS) for a smart city project in Western India. Integrated transportation is one of the enablers of smart transportation for providing a seamless intercity as well as regional level transportation experience. The success of a smart city project at the city level for transportation is providing proper integration to different mass rapid transit modes by way of integrating information, physical, network of routes fares, etc. The methodology adopted for this study was primary data research through questionnaire survey. The respondents of the questionnaire survey have responded on the issues about their perceptions on the ways and means to improve public transport services in urban cities. The respondents were also required to identify the factors and attributes which might motivate more people to shift towards the public mode. Also, the respondents were questioned about the factors which they feel might restrain the integration of various modes of MRTS. Furthermore, this study also focuses on developing a utility equation for respondents with the help of multiple linear regression analysis and its probability to shift to public transport for certain factors listed in the questionnaire. It has been observed that for shifting to public transport, the most important factors that need to be considered were travel time saving and comfort rating. Also, an Integrated MRTS can be obtained by combining metro rail with BRTS, metro rail with monorail, monorail with BRTS and metro rail with Indian railways. Providing a common smart card to transport users for accessing all the different available modes would be a pragmatic solution towards integration of the available modes of MRTS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mass%20rapid%20transit%20systems" title="mass rapid transit systems">mass rapid transit systems</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=metro%20rail" title=" metro rail"> metro rail</a>, <a href="https://publications.waset.org/abstracts/search?q=bus%20rapid%20transit%20system" title=" bus rapid transit system"> bus rapid transit system</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20linear%20regression" title=" multiple linear regression"> multiple linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20card" title=" smart card"> smart card</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20fare%20collection%20system" title=" automated fare collection system"> automated fare collection system</a> </p> <a href="https://publications.waset.org/abstracts/91702/integrated-mass-rapid-transit-system-for-smart-city-project-in-western-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91702.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">271</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">90</span> Improving Fluid Catalytic Cracking Unit Performance through Low Cost Debottlenecking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saidulu%20Gadari">Saidulu Gadari</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar%20Yadav"> Manoj Kumar Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20K.%20Satheesh"> V.

It is the primary source for production of gasoline, light olefins as petrochemical feedstocks, feedstock for alkylate & oxygenates, LPG, etc. in a refinery. Increasing unit capacity and improving product yields as well as qualities such as gasoline RON have dramatic impact on the refinery economics. FCCUs are often debottlenecked significantly beyond their original design capacities. Depending upon the unit configuration, operating conditions, and feedstock quality, the FCC unit can have a variety of bottlenecks. While some of these are aimed to increase the feed rate, improve the conversion, etc., the others are aimed to improve the reliability of the equipment or overall unit. Apart from investment cost, the other factors considered generally while evaluating the debottlenecking options are shutdown days, faster payback, risk on investment, etc. A low-cost solution such as replacement of feed injectors, air distributor, steam distributors, spent catalyst distributor, efficient cyclone system, etc. are the preferred way of upgrading FCCU. It also has lower lead time from idea inception to implementation. This paper discusses various bottlenecks generally encountered in FCCU and presents a case study on improvement of performance of one of the FCCUs in IndianOil through implementation of cost-effective technical solution including use of improved internals in Reactor-Regeneration (R-R) section. After implementation reduction in regenerator air, gas superficial velocity in regenerator and cyclone velocities by about 10% and improvement of CLO yield from 10 to 6 wt% have been achieved. By ensuring proper pressure balance and optimum immersion of cyclone dipleg in the standpipe, frequent formation of perforations in regenerator cyclones could be addressed which in turn improved the unit on-stream factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FCC" title="FCC">FCC</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost" title=" low-cost"> low-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=revamp" title=" revamp"> revamp</a>, <a href="https://publications.waset.org/abstracts/search?q=debottleneck" title=" debottleneck"> debottleneck</a>, <a href="https://publications.waset.org/abstracts/search?q=internals" title=" internals"> internals</a>, <a href="https://publications.waset.org/abstracts/search?q=distributors" title=" distributors"> distributors</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclone" title=" cyclone"> cyclone</a>, <a href="https://publications.waset.org/abstracts/search?q=dipleg" title=" dipleg"> dipleg</a> </p> <a href="https://publications.waset.org/abstracts/60864/improving-fluid-catalytic-cracking-unit-performance-through-low-cost-debottlenecking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60864.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">215</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">89</span> Attention Based Fully Convolutional Neural Network for Simultaneous Detection and Segmentation of Optic Disc in Retinal Fundus Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Sadhukhan">Sandip Sadhukhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arpita%20Sarkar"> Arpita Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Debprasad%20Sinha"> Debprasad Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Kumar%20Ghorai"> Goutam Kumar Ghorai</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Sarkar"> Gautam Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashis%20K.%20Dhara"> Ashis K.

In north-Eastern region of India, there is a scarcity o f stone aggregate. Therefore the road engineers are always in search of an optional material as aggregate which can replace the regularly used material. The purpose of this work was to evaluate the utilization of substandard or marginal aggregates in flexible pavement construction. The investigation was undertaken to evaluate the effects of using lower quality aggregates such as over burnt brick aggregate on the preparation of asphalt concrete for flexible pavements. The scope of this work included a review of available literature and existing data, a laboratory evaluation organized to determine the effects of marginal aggregates and potential techniques to upgrade these substandard materials, and a laboratory evaluation of these upgraded marginal aggregate asphalt mixtures. Over burnt brick aggregates are water susceptible and can leads to moisture damage. Moisture damage is the progressive loss of functionality of the material owing to loss of the adhesion bond between the asphalt binder and the aggregate surface. Hence, zycosoil as an anti striping additive were evaluated in this study. This study summarizes the results of the laboratory evaluation carried out to investigate the properties of asphalt concrete prepared with zycosoil modified over burnt brick aggregate. Marshall specimen were prepared with stone aggregate, zycosoil modified stone aggregate, over burnt brick aggregate and zycosoil modified over burnt brick aggregate. Results show that addition of zycosoil with stone aggregate increased stability by 6% and addition of zycosoil with over burnt brick aggregate increased stability by 30%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt%20concrete" title="asphalt concrete">asphalt concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20burnt%20brick%20aggregate" title=" over burnt brick aggregate"> over burnt brick aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=marshall%20stability" title=" marshall stability"> marshall stability</a>, <a href="https://publications.waset.org/abstracts/search?q=zycosoil" title=" zycosoil"> zycosoil</a> </p> <a href="https://publications.waset.org/abstracts/10998/laboratory-evaluation-of-asphalt-concrete-prepared-with-over-burnt-brick-aggregate-treated-by-zycosoil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10998.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">357</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">87</span> Host-Assisted Delivery of a Model Drug to Genomic DNA: Key Information From Ultrafast Spectroscopy and in Silico Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ria%20Ghosh">Ria Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumendra%20Singh"> Soumendra Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dipanjan%20Mukherjee"> Dipanjan Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Susmita%20Mondal"> Susmita Mondal</a>, <a href="https://publications.waset.org/abstracts/search?q=Monojit%20Das"> Monojit Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Uttam%20Pal"> Uttam Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Aniruddha%20Adhikari"> Aniruddha Adhikari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aman%20Bhushan"> Aman Bhushan</a>, <a href="https://publications.waset.org/abstracts/search?q=Surajit%20Bose"> Surajit Bose</a>, <a href="https://publications.waset.org/abstracts/search?q=Siddharth%20Sankar%20Bhattacharyya"> Siddharth Sankar Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Debasish%20Pal"> Debasish Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanusri%20Saha-Dasgupta"> Tanusri Saha-Dasgupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Maitree%20Bhattacharyya"> Maitree Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Bhattacharyya"> Debasis Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Kumar%20Mallick"> Asim Kumar Mallick</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Das"> Ranjan Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Kumar%20Pal"> Samir Kumar Pal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drug delivery to a target without adverse effects is one of the major criteria for clinical use. Herein, we have made an attempt to explore the delivery efficacy of SDS surfactant in a monomer and micellar stage during the delivery of the model drug, Toluidine Blue (TB) from the micellar cavity to DNA. Molecular recognition of pre-micellar SDS encapsulated TB with DNA occurs at a rate constant of k1 ~652 s 1. However, no significant release of encapsulated TB at micellar concentration was observed within the experimental time frame. This originated from the higher binding affinity of TB towards the nano-cavity of SDS at micellar concentration which does not allow the delivery of TB from the nano-cavity of SDS micelles to DNA. Thus, molecular recognition controls the extent of DNA recognition by TB which in turn modulates the rate of delivery of TB from SDS in a concentration-dependent manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=micelle" title=" micelle"> micelle</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-micelle" title=" pre-micelle"> pre-micelle</a>, <a href="https://publications.waset.org/abstracts/search?q=SDS" title=" SDS"> SDS</a>, <a href="https://publications.waset.org/abstracts/search?q=toluidine%20blue" title=" toluidine blue"> toluidine blue</a> </p> <a href="https://publications.waset.org/abstracts/154090/host-assisted-delivery-of-a-model-drug-to-genomic-dna-key-information-from-ultrafast-spectroscopy-and-in-silico-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154090.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">113</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">86</span> Flow Transformation: An Investigation on Theoretical Aspects and Numerical Computation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhisek%20Sarkar">Abhisek Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhimanyu%20Gaur"> Abhimanyu Gaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this report we have discussed the theoretical aspects of the flow transformation, occurring through a series of bifurcations.

Some have used it as an example to establish nuclear energy as an unsafe source, while others have tried to find the real reasons behind this accident. Many papers have tried to shed light on the possible causes, some of which are purely based on assumptions while others rely on rigorous data analysis. To our best knowledge, none of the works can say with absolute certainty that there is a single prominent reason that has paved the way to this unexpected incident.

The proposed bivariate distribution can be used when the marginals have heavy-tailed distributions, and they have non-monotone hazard functions. Due to the presence of the singular component, it can be used quite effectively when there are ties in the data. Since it has four parameters, it is a very flexible bivariate distribution, and it can be used quite effectively for analyzing various bivariate data sets. Several dependency properties and dependency measures have been obtained. The maximum likelihood estimators cannot be obtained in closed form, and it involves solving a four-dimensional optimization problem. To avoid that, we have proposed to use an EM algorithm, and it involves solving only one non-linear equation at each `E'-step. Hence, the implementation of the proposed EM algorithm is very straight forward in practice. Extensive simulation experiments and the analysis of one data set have been performed. We have observed that the proposed bivariate inverse generalized exponential distribution can be used for modeling dependent competing risks data. One data set has been analyzed to show the effectiveness of the proposed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Block%20and%20Basu%20bivariate%20distributions" title="Block and Basu bivariate distributions">Block and Basu bivariate distributions</a>, <a href="https://publications.waset.org/abstracts/search?q=competing%20risks" title=" competing risks"> competing risks</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20algorithm" title=" EM algorithm"> EM algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=Marshall-Olkin%20bivariate%20exponential%20distribution" title=" Marshall-Olkin bivariate exponential distribution"> Marshall-Olkin bivariate exponential distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20likelihood%20estimators" title=" maximum likelihood estimators"> maximum likelihood estimators</a> </p> <a href="https://publications.waset.org/abstracts/122524/a-bivariate-inverse-generalized-exponential-distribution-and-its-applications-in-dependent-competing-risks-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122524.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">143</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">82</span> Inference for Compound Truncated Poisson Lognormal Model with Application to Maximum Precipitation Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Z.%20Raqab">M.

One important point to mention is that some stations are shut down on certain days for some reason or the other. Hence, the maximum values are recorded by excluding those readings. It is assumed that the number of stations that operate follows zero-truncated Poisson random variables, and the daily precipitation follows a lognormal random variable. We call this model a compound truncated Poisson lognormal model. The proposed model has three unknown parameters, and it can take a variety of shapes. The maximum likelihood estimators can be obtained quite conveniently using Expectation-Maximization (EM) algorithm. Approximate maximum likelihood estimators are also derived. The associated confidence intervals also can be obtained from the observed Fisher information matrix. Simulation results have been performed to check the performance of the EM algorithm, and it is observed that the EM algorithm works quite well in this case. When we analyze the precipitation data set using the proposed model, it is observed that the proposed model provides a better fit than some of the existing models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compound%20Poisson%20lognormal%20distribution" title="compound Poisson lognormal distribution">compound Poisson lognormal distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20algorithm" title=" EM algorithm"> EM algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20likelihood%20estimation" title=" maximum likelihood estimation"> maximum likelihood estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=approximate%20maximum%20likelihood%20estimation" title=" approximate maximum likelihood estimation"> approximate maximum likelihood estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=Fisher%20information" title=" Fisher information"> Fisher information</a>, <a href="https://publications.waset.org/abstracts/search?q=skew%20distribution" title=" skew distribution"> skew distribution</a> </p> <a href="https://publications.waset.org/abstracts/156020/inference-for-compound-truncated-poisson-lognormal-model-with-application-to-maximum-precipitation-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156020.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">108</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">81</span> Effect of Sedimentation on Torque Transmission in the Larger Radius Magnetorheological Clutch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manish%20Kumar%20Thakur">Manish Kumar Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiranjit%20Sarkar"> Chiranjit Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sedimentation of magnetorheological (MR) fluid affects its working.

We also analyse the issue of how to choose the parameters of the GEMC simulation optimally. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autocorrelation%20function" title="autocorrelation function">autocorrelation function</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20fluctuation" title=" density fluctuation"> density fluctuation</a>, <a href="https://publications.waset.org/abstracts/search?q=GEMC" title=" GEMC"> GEMC</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/131552/multiple-relaxation-times-in-the-gibbs-ensemble-monte-carlo-simulation-of-phase-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131552.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">189</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">78</span> Assessing the Impact of Social Media on Tourism Industry: Setting Proposition for State Government of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Utkrash%20Sarkar">Utkrash Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vineet%20Tiwari"> Vineet Tiwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Shailendra%20Singh"> Shailendra Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of social media has brought about a tremendous change in the marketing scenario for every industry.

Diabetic retinopathy (DR) is damage to the retina that occurs with long-term diabetes. DR is a major cause of blindness in the Indian population. Therefore, its early diagnosis is of utmost importance towards preventing progression towards imminent irreversible loss of vision, particularly in the huge population across rural India. The barriers to eye examination of all diabetic patients are socioeconomic factors, lack of referrals, poor access to the healthcare system, lack of knowledge, insufficient number of ophthalmologists, and lack of networking between physicians, diabetologists and ophthalmologists. A few diabetic patients often visit a healthcare facility for their general checkup, but their eye condition remains largely undetected until the patient is symptomatic. This work aims to focus on the design and development of a fully automated intelligent decision system for screening retinal fundus images towards detection of the pathophysiology caused by microaneurysm in the early stage of the diseases. Automated detection of microaneurysm is a challenging problem due to the variation in color and the variation introduced by the field of view, inhomogeneous illumination, and pathological abnormalities. We have developed aconvolutional neural network for efficient detection of microaneurysm. A loss function is also developed to handle severe class imbalance due to very small size of microaneurysms compared to background. The network is able to locate the salient region containing microaneurysms in case of noisy images captured by non-mydriatic cameras. The ground truth of microaneurysms is created by expert ophthalmologists for MESSIDOR database as well as private database, collected from Indian patients. The network is trained from scratch using the fundus images of MESSIDOR database. The proposed method is evaluated on DIARETDB1 and the private database. The method is successful in detection of microaneurysms for dilated and non-dilated types of fundus images acquired from different medical centres. The proposed algorithm could be used for development of AI based affordable and accessible system, to provide service at grass root-level primary healthcare units spread across the country to cater to the need of the rural people unaware of the severe impact of DR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retinal%20fundus%20image" title="retinal fundus image">retinal fundus image</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20convolutional%20neural%20network" title=" deep convolutional neural network"> deep convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20detection%20of%20microaneurysms" title=" early detection of microaneurysms"> early detection of microaneurysms</a>, <a href="https://publications.waset.org/abstracts/search?q=screening%20of%20diabetic%20retinopathy" title=" screening of diabetic retinopathy"> screening of diabetic retinopathy</a> </p> <a href="https://publications.waset.org/abstracts/112349/deep-convolutional-neural-network-for-detection-of-microaneurysms-in-retinal-fundus-images-at-early-stage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112349.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">142</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">75</span> An Unusual Fracture Pattern: Fracture of the Distal Radius (Colles') along with Fracture of the Ipsilateral Scaphoid & Capitate Bones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srikanta%20Tagore%20Sarkar">Srikanta Tagore Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20Kumar%20Mandal"> Prasanta Kumar Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dibakar%20Roy"> Dibakar Roy </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The association of a capitate fracture with a scaphoid fracture has been termed as the naviculocapitate syndrome.

It contains the IFR class of distributions and is contained in the NBUE class of distributions. While upper and lower bounds of the reliability distribution function of aging classes such as IFR, IFRA, NBU, NBUE, and HNBUE have discussed in the literature for a long time, there is no analogous result available for the DMRL class. We obtain the upper and lower bounds for the reliability function of the DMRL class in terms of first order finite moment. The lower bound is obtained by showing that for any fixed time, the minimization of the reliability function over the class of all DMRL distributions with a fixed mean is equivalent to its minimization over a smaller class of distribution with a special form. Optimization over this restricted set can be made algebraically. Likewise, the maximization of the reliability function over the class of all DMRL distributions with a fixed mean turns out to be a parametric optimization problem over the class of DMRL distributions of a special form. The constructive proofs also establish that both the upper and lower bounds are sharp. Further, the DMRL upper bound coincides with the HNBUE upper bound and the lower bound coincides with the IFR lower bound. We also prove that a pair of sharp upper and lower bounds for the reliability function when the distribution is increasing mean residual life (IMRL) with a fixed mean. This result is proved in a similar way. These inequalities fill a long-standing void in the literature of the life distribution modeling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DMRL" title="DMRL">DMRL</a>, <a href="https://publications.waset.org/abstracts/search?q=IMRL" title=" IMRL"> IMRL</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20bounds" title=" reliability bounds"> reliability bounds</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20functions" title=" hazard functions"> hazard functions</a> </p> <a href="https://publications.waset.org/abstracts/47988/first-order-moment-bounds-on-dmrl-and-imrl-classes-of-life-distributions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47988.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">397</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">73</span> A Terahertz Sensor and Dynamic Switch Based on a Bilayer Toroidal Metamaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angana%20Bhattacharya">Angana Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Sarkar"> Rakesh Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Gagan%20Kumar"> Gagan Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Toroidal resonances, a new class of electromagnetic excitations, demonstrate exceptional properties as compared to electric and magnetic dipolar resonances. The advantage of narrow linewidth in toroidal resonance is utilized in this proposed work, where a bilayer metamaterial (MM) sensor has been designed in the terahertz frequency regime (THz). A toroidal MM geometry in a single layer is first studied. A second identical MM geometry placed on top of the first layer results in the coupling of toroidal excitations, leading to an increase in the quality factor (Q) of the resonance. The sensing capability of the resonance is studied. Further, the dynamic switching from an 'off' stage to an 'on' stage in the bilayer configuration is explored.

In some problem domains such as scientific simulations, available computational power still sets a limit on what can be practically explored in computation. For many types of code, there is non-uniformity in the utility of computation. That is not every piece of computation contributes equally to the quality of the result. If this non-uniformity is understood well and exploited effectively, we can much more effectively utilize available computing power. In this paper, we discuss a case study of exploring such non-uniformity in a particle-in-cell simulation platform. We find both the existence of significant non-uniformity and that it is generally straightforward to exploit it. We show the potential of order-of-magnitude effective performance gain while keeping the comparable quality of output. We also discuss some challenges in both the practical application of the idea and evaluation of its impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=approximate%20computing" title="approximate computing">approximate computing</a>, <a href="https://publications.waset.org/abstracts/search?q=landau%20damping" title=" landau damping"> landau damping</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20uniform%20utility%20computing" title=" non uniform utility computing"> non uniform utility computing</a>, <a href="https://publications.waset.org/abstracts/search?q=particle-in-cell" title=" particle-in-cell"> particle-in-cell</a> </p> <a href="https://publications.waset.org/abstracts/86032/exploiting-non-uniform-utility-of-computing-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86032.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">259</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> Analysing the Behaviour of Local Hurst Exponent and Lyapunov Exponent for Prediction of Market Crashes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shreemoyee%20Sarkar">Shreemoyee Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikhyat%20Chadha"> Vikhyat Chadha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the local fractal properties and chaotic properties of financial time series are investigated by calculating two exponents, the Local Hurst Exponent: LHE and Lyapunov Exponent in a moving time window of a financial series.y.

The remarkable electrochemical property of the large surface area nano-heterostructures is demonstrated based on the novel nano-architectural design of the electrode with the coexistence of the two highly redox active materials at the surface supported by highly conducting metal alloy channel at the core for faster charge transport. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano-heterostructures" title="nano-heterostructures">nano-heterostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitors" title=" supercapacitors"> supercapacitors</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20deposition" title=" electrochemical deposition"> electrochemical deposition</a> </p> <a href="https://publications.waset.org/abstracts/15453/unique-nio-based-1-d-coreshell-nano-heterostructure-electrodes-for-high-performance-supercapacitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15453.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">326</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> Studying the Behavior of Asphalt Mix and Their Properties in the Presence of Nano Materials </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aman%20Patidar">Aman Patidar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dipankar%20Sarkar"> Dipankar Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manish%20Pal"> Manish Pal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to rapid development, increase in the traffic load, higher traffic volume and seasonal variation in temperature, asphalt pavement shows distresses like rutting, fatigue and thermal cracking etc. because of this pavement fails during service life so that bitumen needs to be modified with some additive. In this study VG30 grade bitumen modify with addition of nanosilica with 1% to 5% (increment of 1%) by weight of bitumen. Hot mix asphalt (HMA) have higher mixing, laying and rolling temperatures which leads to higher consumption of fuel. To address this issue, a nano material named ZycoTherm which is chemical warm mix asphalt (WMA) additive is added to bitumen. Nanosilica modification (NSMB) results in the increase in stability compared to unmodified bitumen (UMB). WMA modified mix shows slightly higher stability than UMB and NSMB in a lower bitumen content. The Retained stability and tensile strength ratio (TSR) is more than 75% and 80% respectively for both mixes. Nanosilica with WMA has more resistant to temperature susceptibility, moisture susceptibility and short term aging than NSMB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HMA" title="HMA">HMA</a>, <a href="https://publications.waset.org/abstracts/search?q=nanosilica" title=" nanosilica"> nanosilica</a>, <a href="https://publications.waset.org/abstracts/search?q=NSMB" title=" NSMB"> NSMB</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=TSR" title=" TSR"> TSR</a>, <a href="https://publications.waset.org/abstracts/search?q=UMB" title=" UMB"> UMB</a>, <a href="https://publications.waset.org/abstracts/search?q=WMA" title=" WMA"> WMA</a> </p> <a href="https://publications.waset.org/abstracts/77781/studying-the-behavior-of-asphalt-mix-and-their-properties-in-the-presence-of-nano-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77781.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">311</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">67</span> Quantum Dot Biosensing for Advancing Precision Cancer Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sourav%20Sarkar">Sourav Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manashjit%20Gogoi"> Manashjit Gogoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the evolving landscape of cancer diagnostics, optical biosensing has emerged as a promising tool due to its sensitivity and specificity. This study explores the potential of CdS/ZnS core-shell quantum dots (QDs) capped with 3-Mercaptopropionic acid (3-MPA), which aids in the linking chemistry of QDs to various cancer antibodies. The QDs, with their unique optical and electronic properties, have been integrated into the biosensor design. Their high quantum yield and size-dependent emission spectra have been exploited to improve the sensor’s detection capabilities. The study presents the design of this QD-enhanced optical biosensor. The use of these QDs can also aid multiplexed detection, enabling simultaneous monitoring of different cancer biomarkers. This innovative approach holds significant potential for advancing cancer diagnostics, contributing to timely and accurate detection. Future work will focus on optimizing the biosensor design for clinical applications and exploring the potential of QDs in other biosensing applications. This study underscores the potential of integrating nanotechnology and biosensing for cancer research, paving the way for next-generation diagnostic tools. It is a step forward in our quest for achieving precision oncology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20dots"
