In the present study, platinum nano particles have been utilized to achieve the improved properties. Polyaniline and Pt-polyaniline composite are synthesized by chemical routes. The samples characterized by X-ray diffractometer show the amorphous nature of polyaniline and Pt-polyaniline composite. The Bragg’s diffraction peaks correspond to platinum nano particles and thermogravimetric analyzer predicts its decomposition at certain temperature. The current-potential characteristics of the samples are also studied which indicate a significant increasing the value of conductivity after introduction of pt nanoparticles in the matrix of polyaniline (PANI). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyaniline" title="polyaniline">polyaniline</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD%20and%20platinum%20nanoparticles" title=" XRD and platinum nanoparticles"> XRD and platinum nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20sciences" title=" pharmaceutical sciences"> pharmaceutical sciences</a> </p> <a href="https://publications.waset.org/abstracts/26283/preparation-and-characterization-of-polyaniline-pani-platinum-nanocomposite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26283.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">543</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> ChaQra: A Cellular Unit of the Indian Quantum Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shashank%20Gupta">Shashank Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Iteash%20Agarwal"> Iteash Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijayalaxmi%20Mogiligidda"> Vijayalaxmi Mogiligidda</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar%20Krishnan"> Rajesh Kumar Krishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sruthi%20Chennuri"> Sruthi Chennuri</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepika%20Aggarwal"> Deepika Aggarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anwesha%20Hoodati"> Anwesha Hoodati</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheroy%20Cooper"> Sheroy Cooper</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan"> Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Bilal%20Sheik"> Mohammad Bilal Sheik</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhavya%20K.%20M."> Bhavya K.

It is great to push the boundaries on these fronts, but these isolated approaches are neither scalable nor cost-effective due to the requirements of specialised hardware and different infrastructure. Current and future QKD network requires addressing different sets of challenges apart from distance, key rate, and quantum security. In this regard, we present ChaQra -a sub-quantum network with core features as 1) Crypto agility (integration in the already deployed telecommunication fibres), 2) Software defined networking (SDN paradigm for routing different nodes), 3) reliability (addressing denial-of-service with hybrid quantum safe cryptography), 4) upgradability (modules upgradation based on scientific and technological advancements), 5) Beyond QKD (using QKD network for distributed computing, multi-party computation etc). Our results demonstrate a clear path to create and accelerate quantum secure Indian subcontinent under the national quantum mission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20network" title="quantum network">quantum network</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20key%20distribution" title=" quantum key distribution"> quantum key distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20security" title=" quantum security"> quantum security</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20information" title=" quantum information"> quantum information</a> </p> <a href="https://publications.waset.org/abstracts/186156/chaqra-a-cellular-unit-of-the-indian-quantum-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186156.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">56</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">77</span> Relationship between Growth of Non-Performing Assets and Credit Risk Management Practices in Indian Banks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sirus%20Sharifi">Sirus Sharifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arunima%20Haldar"> Arunima Haldar</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20V.%20D.%20Nageswara%20Rao"> S.

In this paper, the mechanical behaviours of Ti/GFRP/Ti laminates were experimentally investigated through low-velocity impact tests. Two different surface treatments of Titanium (Ti-6Al-4V) alloy sheets were prepared to obtain the composite interface properties based on annealing and sandblast surface treatment processes. The deformation failure modes, impact load sustaining ability and energy absorption capacity of FMLs were analysed. The impact load and modulus were shown to be dependent on the surface treatments of Titanium (Ti-6Al-4V) alloy sheets. It was demonstrated that the impact load performance was enhanced when titanium surfaces were annealed and sandblasted. It has also been shown that the values of the strength and energy absorption were slightly higher when the tests conducted at relatively higher loading rate, as a result of the rate-sensitive effects on the damage resistance of the FML. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiber%20metal%20laminates" title="fiber metal laminates">fiber metal laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20composite%20interface" title=" metal composite interface"> metal composite interface</a>, <a href="https://publications.waset.org/abstracts/search?q=indentation" title=" indentation"> indentation</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20velocity%20impact" title=" low velocity impact"> low velocity impact</a> </p> <a href="https://publications.waset.org/abstracts/140171/mechanical-behaviours-of-tigfrpti-laminates-with-different-surface-treatments-of-titanium-sheets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140171.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">197</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">74</span> Effects of the Mass and Damping Matrix Model in the Non-Linear Seismic Response of Steel Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Reyes-Salazar">Alfredo Reyes-Salazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20D.%20Llanes-Tizoc"> Mario D.

Similarly, the initial stiffness matrix (KO) and the first two modes associated with lateral vibrations are commonly used to develop matrix C. The evaluation of the accuracy of these practices for the particular case of steel buildings with moment-resisting steel frames constitutes the main objective of this research. For this, the non-linear seismic responses of three models of steel frames, representing low-, medium- and high-rise steel buildings, are considered. Results indicate that if the ML matrix is used, shears and bending moments in columns are underestimated by up to 30% and 65%, respectively when compared to the corresponding results obtained with the consistent mass matrix (MC). It is also shown that if KO is used in C instead of the tangent stiffness matrix (Kt), axial loads in columns are underestimated by up to 80%. It is concluded that the consistent mass matrix should be used in the structural modelling of moment-resisting steel frames and that the tangent stiffness matrix should be used to develop the Rayleigh damping matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moment-resisting%20steel%20frames" title="moment-resisting steel frames">moment-resisting steel frames</a>, <a href="https://publications.waset.org/abstracts/search?q=consistent%20and%20concentrated%20mass%20matrices" title=" consistent and concentrated mass matrices"> consistent and concentrated mass matrices</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20seismic%20response" title=" non-linear seismic response"> non-linear seismic response</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayleigh%20damping" title=" Rayleigh damping"> Rayleigh damping</a> </p> <a href="https://publications.waset.org/abstracts/153538/effects-of-the-mass-and-damping-matrix-model-in-the-non-linear-seismic-response-of-steel-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153538.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">149</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> Design Guidelines for URM Infills and Effect of Construction Sequence on Seismic Performance of Code Compliant RC Frame Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Putul%20Haldar">Putul Haldar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yogendra%20Singh"> Yogendra Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20K.%20Paul"> D.

Although the behavior and failure pattern of the global structure changes significantly due to infill-frame interaction, the general design practice is to treat them as non-structural elements and their stiffness, strength and interaction with frame is often ignored, as it is difficult to simulate. Indian Standard, like many other major national codes, does not provide any explicit guideline for modeling of infills. This paper takes a stock of controlling design provisions in some of the major national seismic design codes (BIS 2002; CEN 2004; NZS-4230 2004; ASCE-41 2007) to ensure the desired seismic performance of infilled frame. Most of the national codes on seismic design of buildings still lack in adequate guidelines on modeling and design of URM infilled frames results in variable assumption in analysis and design. This paper, using nonlinear pushover analysis, also presents the effect of one of such assumptions of conventional ‘simultaneous’ analysis procedure of infilled frame on the seismic performance of URM infilled RC frame buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=URM%20infills" title="URM infills">URM infills</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20frame" title=" RC frame"> RC frame</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20design%20codes" title=" seismic design codes"> seismic design codes</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20sequence%20of%20infilled%20frame" title=" construction sequence of infilled frame"> construction sequence of infilled frame</a> </p> <a href="https://publications.waset.org/abstracts/4380/design-guidelines-for-urm-infills-and-effect-of-construction-sequence-on-seismic-performance-of-code-compliant-rc-frame-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4380.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">389</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">72</span> An Improved VM Allocation Algorithm by Utilizing Combined Resource Allocation Mechanism and Released Resources in Cloud Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md%20Habibul%20Ansary">Md Habibul Ansary</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandan%20Garai"> Chandan Garai</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Dasgupta"> Ranjan Dasgupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Utilization of resources is always a great challenge for any allocation problem, particularly when resource availability is dynamic in nature. In this work VM allocation mechanism has been augmented by providing resources in a combined manner. This approach has some inherent advantages in terms of reduction of wait state for the pending jobs of some users and better utilization of unused resources from the service providers’ point of view. Moreover the algorithm takes care of released resources from the finished jobs as soon as those become available. The proposed algorithm has been explained by suitable example to make the work complete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bid%20ratio" title="Bid ratio">Bid ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20service" title=" cloud service"> cloud service</a>, <a href="https://publications.waset.org/abstracts/search?q=virtualization" title=" virtualization"> virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=VM%20allocation%20problem" title=" VM allocation problem"> VM allocation problem</a> </p> <a href="https://publications.waset.org/abstracts/34024/an-improved-vm-allocation-algorithm-by-utilizing-combined-resource-allocation-mechanism-and-released-resources-in-cloud-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34024.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">396</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">71</span> Frequency Reconfigurable Multiband Patch Antenna Using PIN-Diode for ITS Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Upadhyay">Gaurav Upadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20Kishore"> Nand Kishore</a>, <a href="https://publications.waset.org/abstracts/search?q=Prashant%20Ranjan"> Prashant Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20S.%20Tripathi"> V.

We have developed novel high-throughput capable assays for ribosome targeted drug discovery. One such assay examines the compounds ability to bind to a model ribosomal RNA A-site. We have also coupled this assay to other functional orthogonal assays. Such analysis can provide valuable understanding of the relationships between two complementary drug screening methods and could be used as standard analysis to correlate the affinity of a compound for its target and the effect the compound has on a cell. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20resistance" title="bacterial resistance">bacterial resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=aminoglycosides" title=" aminoglycosides"> aminoglycosides</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs" title=" drugs"> drugs</a> </p> <a href="https://publications.waset.org/abstracts/16341/novel-aminoglycosides-to-target-resistant-pathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16341.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">370</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> PIN-Diode Based Slotted Reconfigurable Multiband Antenna Array for Vehicular Communication </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Upadhyay">Gaurav Upadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20Kishore"> Nand Kishore</a>, <a href="https://publications.waset.org/abstracts/search?q=Prashant%20Ranjan"> Prashant Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivesh%20Tripathi"> Shivesh Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20S.%20Tripathi"> V.

The antenna consists of 2-element patch array. The antenna array is operating at multiple frequency bands. The multiband operation is achieved by use of slots at proper locations at the patch. The array is made reconfigurable by use of two PIN-diodes. The antenna is simulated and measured in four states of diodes i.e. ON-ON, ON-OFF, OFF-ON, and OFF-OFF. In ON-ON state of diodes, the resonant frequencies are 4.62-4.96, 6.50-6.75, 6.90-7.01, 7.34-8.22, 8.89-9.09 GHz. In ON-OFF state of diodes, the measured resonant frequencies are 4.63-4.93, 6.50-6.70 and 7.81-7.91 GHz. In OFF-ON states of diodes the resonant frequencies are 1.24-1.46, 3.40-3.75, 5.07-5.25 and 6.90-7.20 GHz and in the OFF-OFF state of diodes 4.49-4.75 and 5.61-5.98 GHz. The maximum bandwidth of the proposed antenna is 16.29%. The peak gain of the antenna is 3.4 dB at 5.9 GHz, which makes it suitable for vehicular communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antenna" title="antenna">antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=array" title=" array"> array</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable" title=" reconfigurable"> reconfigurable</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicular" title=" vehicular"> vehicular</a> </p> <a href="https://publications.waset.org/abstracts/85090/pin-diode-based-slotted-reconfigurable-multiband-antenna-array-for-vehicular-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85090.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">256</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Perception of Women towards Participation in Employment: A Study on Mumbai Slums Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukesh%20Ranjan">Mukesh Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Varsha%20Nagargoje"> Varsha Nagargoje</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Applying the exploratory factor analysis (EFA), Women Employment Participation Perception Index (WEPPI) has been made through 13 components.

Due to low mechanical stability, flooding and fuel cell crossover, application of phosphoric acid in polymeric membrane is very critical. Phosphorous and silica based 3D inorganic gel gains the attention in the field of supercapacitors, fuel cells and metal hydrate batteries due to its thermally stable highly proton conductive behavior. Also as a large amount of water molecule and phosphoric acid can easily get trapped in Si-O-Si network cavities, it causes a prevention in the leaching out. In this study, we have performed molecular dynamics (MD) simulation and first principle calculations to understand the structural, electronics and electrochemical and morphological behavior of this inorganic gel at various P to Si ratios. We have used dipole-dipole interactions, H bonding, and van der Waals forces to study the main interactions between the molecules. A 'structure property-performance' mapping is initiated to determine optimum P to Si ratio for best proton conductivity. We have performed the MD simulations at various temperature to understand the temperature dependency on proton conductivity. The observed results will propose a model which fits well with experimental data and other literature values. We have also studied the mechanism behind proton conductivity. And finally we have proposed a structure for the gel paste with optimum P to Si ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=first%20principle%20calculation" title="first principle calculation">first principle calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorous%20and%20silica%20based%203D%20inorganic%20gel" title=" phosphorous and silica based 3D inorganic gel"> phosphorous and silica based 3D inorganic gel</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20electrolyte%20membrane%20fuel%20cells" title=" polymer electrolyte membrane fuel cells"> polymer electrolyte membrane fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20conductivity" title=" proton conductivity"> proton conductivity</a> </p> <a href="https://publications.waset.org/abstracts/101031/study-of-structural-behavior-and-proton-conductivity-of-inorganic-gel-paste-electrolyte-at-various-phosphorous-to-silicon-ratio-by-multiscale-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101031.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">129</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">63</span> Channel Characteristics and Morphometry of a Part of Umtrew River, Meghalaya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratyashi%20Phukan">Pratyashi Phukan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Saikia"> Ranjan Saikia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Morphometry incorporates quantitative study of the area ,altitude,volume, slope profiles of a land and drainage basin characteristics of the area concerned.Fluvial geomorphology includes the consideration of linear,areal and relief aspects of a fluvially originated drainage basin.

Our early requirement analysis shows that how means end analysis reveals gaps and inconsistencies in early requirements specifications that are by no means trivial to discover without the help of formal analysis tool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20courseware" title="adaptive courseware">adaptive courseware</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20requirement%20engineering" title=" early requirement engineering"> early requirement engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=means%20end%20analysis" title=" means end analysis"> means end analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20modelling" title=" organizational modelling"> organizational modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=requirement%20modelling" title=" requirement modelling"> requirement modelling</a> </p> <a href="https://publications.waset.org/abstracts/8626/early-requirement-engineering-for-design-of-learner-centric-dynamic-lms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8626.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">500</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">61</span> Model Based Simulation Approach to a 14-Dof Car Model Using Matlab/Simulink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishit%20Sheth">Ishit Sheth</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandrasekhar%20Jinendran"> Chandrasekhar Jinendran</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinmaya%20Ranjan%20Sahu"> Chinmaya Ranjan Sahu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A fourteen degree of freedom (DOF) ride and handling control mathematical model is developed for a car using generalized boltzmann hamel equation which will create a basis for design of ride and handling controller. Mathematical model developed yield equations of motion for non-holonomic constrained systems in quasi-coordinates. The governing differential equation developed integrates ride and handling control of car. Model-based systems engineering approach is implemented for simulation using matlab/simulink, vehicle’s response in different DOF is examined and later validated using commercial software (ADAMS).

This research article investigates the damage pattern and most probable reason of failure by observing photographs of seven major buildings collapsed/damaged which were evenly spread over the region during Mw7.8, Nepal earthquake 2015 followed by more than 400 aftershocks of Mw4 with one aftershock reaching a magnitude of Mw7.3. Over 250,000 buildings got damaged, and more than 9000 people got injured in this earthquake. Photographs of these buildings were collected after the earthquake and the cause of failure was estimated along with the severity of damage and comment on the reparability of structure has been made. Based on observations, it was concluded that the damage in reinforced concrete buildings was less compared to masonry structures. The number of buildings damaged was high near Kathmandu region due to high building density in that region. This type of damage analysis can be used as a cost effective and quick method for damage assessment during earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nepal%20earthquake" title="Nepal earthquake">Nepal earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20analysis" title=" damage analysis"> damage analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20assessment" title=" damage assessment"> damage assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20scales" title=" damage scales"> damage scales</a> </p> <a href="https://publications.waset.org/abstracts/54094/overview-and-post-damage-analysis-of-nepal-earthquake-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54094.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">374</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">58</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">57</span> Parametric Study of Ball and Socket Joint for Bio-Mimicking Exoskeleton</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukesh%20Roy">Mukesh Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Basant%20Singh%20Sikarwar"> Basant Singh Sikarwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ravi%20Prakash"> Ravi Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Priya%20Ranjan"> Priya Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayush%20Goyal"> Ayush Goyal </a> </p> <p class="card-text"><strong>Abstract:</strong></p> More than 11% of people suffer from weakness in the bone resulting in inability in walking or climbing stairs or from limited upper body and limb immobility. This motivates a fresh bio-mimicking solution to the design of an exo-skeleton to support human movement in the case of partial or total immobility either due to congenital or genetic factors or due to some accident or due to geratological factors. A deeper insight and detailed understanding is required into the workings of the ball and socket joints. Our research is to mimic ball and socket joints to design snugly fitting exoskeletons. Our objective is to design an exoskeleton which is comfortable and the presence of which is not felt if not in use. Towards this goal, a parametric study is conducted to provide detailed design parameters to fabricate an exoskeleton. This work builds up on real data of the design of the exoskeleton, so that the designed exo-skeleton will be able to provide required strength and support to the subject. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-mimicking" title="bio-mimicking">bio-mimicking</a>, <a href="https://publications.waset.org/abstracts/search?q=exoskeleton" title=" exoskeleton"> exoskeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=ball%20joint" title=" ball joint"> ball joint</a>, <a href="https://publications.waset.org/abstracts/search?q=socket%20joint" title=" socket joint"> socket joint</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20limb" title=" artificial limb"> artificial limb</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20rehabilitation" title=" patient rehabilitation"> patient rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=joints" title=" joints"> joints</a>, <a href="https://publications.waset.org/abstracts/search?q=human-machine%20interface" title=" human-machine interface"> human-machine interface</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20robotics" title=" wearable robotics"> wearable robotics</a> </p> <a href="https://publications.waset.org/abstracts/37015/parametric-study-of-ball-and-socket-joint-for-bio-mimicking-exoskeleton" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37015.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">295</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">56</span> Improved Acoustic Source Sensing and Localization Based On Robot Locomotion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Ramu%20Reddy">V.

The developed methodology includes an acoustic based sensing and localization system, a converging target localization based on the recursive direction of arrival (DOA) error minimization, and a regressive obstacle avoidance function. Our method is able to augment the existing proven localization techniques and improve results incrementally by utilizing robot locomotion and is capable of converging to a position estimate with greater accuracy using fewer measurements. The results also evinced the DOA error minimization at each iteration, improvement in time for reaching the destination and the efficiency of this target localization method as gradually converging to the real target position.

Once the individual cells are validated, then the tandem structure is modelled with Indium Tin Oxide(ITO) as conducting layer between the top and bottom cells. The tandem structure yielded better open circuit voltage and fill factor; however, the efficiency obtained is 7.01%. The top cell and the bottom cells are investigated with the help of electron-hole current density, photogeneration rate, and external quantum efficiency profiles. In order to minimize the various loss mechanisms in the tandem solar cell, the material parameters are optimized within experimentally achievable limits.

It comes from slag formers such as burned lime/dolomite and from oxidizing of silica, iron etc. while refining the iron into steel in the LD furnace. Although a number of ways for its utilization have been suggested, its potential as a filler material in polymeric matrices has not yet been explored. The present work reports the possible use of this waste in glass fiber reinforced epoxy composites as a filler material. Hybrid composites consisting of bi-directional e-glass-fiber reinforced epoxy filled with different LD slag content (0, 7.5, 15, 22.5 wt%) are prepared by simple hand lay-up technique. The composites are characterized in regard to their density, porosity, micro-hardness and strength properties. X-ray diffractography is carried out in order to ascertain the various phases present in LDS. This work shows that LD slag, in spite of being a waste, possesses fairly good filler characteristics as it modifies the strength properties and improves the composite micro-hardness of the polymeric resin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characterization" title="characterization">characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=glass-epoxy%20composites" title=" glass-epoxy composites"> glass-epoxy composites</a>, <a href="https://publications.waset.org/abstracts/search?q=LD%20slag" title=" LD slag"> LD slag</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20utilization" title=" waste utilization "> waste utilization </a> </p> <a href="https://publications.waset.org/abstracts/9085/processing-and-characterization-of-glass-epoxy-composites-filled-with-linz-donawitz-ld-slag" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9085.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">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Supervised/Unsupervised Mahalanobis Algorithm for Improving Performance for Cyberattack Detection over Communications Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radhika%20Ranjan%20Roy">Radhika Ranjan Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deployment of machine learning (ML)/deep learning (DL) algorithms for cyberattack detection in operational communications networks (wireless and/or wire-line) is being delayed because of low-performance parameters (e.g., recall, precision, and f₁-score). If datasets become imbalanced, which is the usual case for communications networks, the performance tends to become worse. Complexities in handling reducing dimensions of the feature sets for increasing performance are also a huge problem. Mahalanobis algorithms have been widely applied in scientific research because Mahalanobis distance metric learning is a successful framework. In this paper, we have investigated the Mahalanobis binary classifier algorithm for increasing cyberattack detection performance over communications networks as a proof of concept. We have also found that high-dimensional information in intermediate features that are not utilized as much for classiﬁcation tasks in ML/DL algorithms are the main contributor to the state-of-the-art of improved performance of the Mahalanobis method, even for imbalanced and sparse datasets. With no feature reduction, MD offers uniform results for precision, recall, and f₁-score for unbalanced and sparse NSL-KDD datasets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahalanobis%20distance" title="Mahalanobis distance">Mahalanobis distance</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=NS-KDD" title=" NS-KDD"> NS-KDD</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20intrinsic%20dimensionality" title=" local intrinsic dimensionality"> local intrinsic dimensionality</a>, <a href="https://publications.waset.org/abstracts/search?q=chi-square" title=" chi-square"> chi-square</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20semi-definite" title=" positive semi-definite"> positive semi-definite</a>, <a href="https://publications.waset.org/abstracts/search?q=area%20under%20the%20curve" title=" area under the curve"> area under the curve</a> </p> <a href="https://publications.waset.org/abstracts/161865/supervisedunsupervised-mahalanobis-algorithm-for-improving-performance-for-cyberattack-detection-over-communications-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161865.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">52</span> Modern Proteomics and the Application of Machine Learning Analyses in Proteomic Studies of Chronic Kidney Disease of Unknown Etiology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dulanjali%20Ranasinghe">Dulanjali Ranasinghe</a>, <a href="https://publications.waset.org/abstracts/search?q=Isuru%20Supasan"> Isuru Supasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaushalya%20Premachandra"> Kaushalya Premachandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Dissanayake"> Ranjan Dissanayake</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajith%20Rajapaksha"> Ajith Rajapaksha</a>, <a href="https://publications.waset.org/abstracts/search?q=Eustace%20Fernando"> Eustace Fernando</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proteomics studies of organisms are considered to be significantly information-rich compared to their genomic counterparts because proteomes of organisms represent the expressed state of all proteins of an organism at a given time. In modern top-down and bottom-up proteomics workflows, the primary analysis methods employed are gel–based methods such as two-dimensional (2D) electrophoresis and mass spectrometry based methods. Machine learning (ML) and artificial intelligence (AI) have been used increasingly in modern biological data analyses. In particular, the fields of genomics, DNA sequencing, and bioinformatics have seen an incremental trend in the usage of ML and AI techniques in recent years. The use of aforesaid techniques in the field of proteomics studies is only beginning to be materialised now. Although there is a wealth of information available in the scientific literature pertaining to proteomics workflows, no comprehensive review addresses various aspects of the combined use of proteomics and machine learning. The objective of this review is to provide a comprehensive outlook on the application of machine learning into the known proteomics workflows in order to extract more meaningful information that could be useful in a plethora of applications such as medicine, agriculture, and biotechnology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proteomics" title="proteomics">proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=gel-based%20proteomics" title=" gel-based proteomics"> gel-based proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/137471/modern-proteomics-and-the-application-of-machine-learning-analyses-in-proteomic-studies-of-chronic-kidney-disease-of-unknown-etiology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137471.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">151</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">51</span> Integration of Artificial Neural Network with Geoinformatics Technology to Predict Land Surface Temperature within Sun City Jodhpur, Rajasthan, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Kumar%20Ranjan">Avinash Kumar Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Akash%20Anand"> Akash Anand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Land Surface Temperature (LST) is an essential factor accompanying to rise urban heat and climate warming within a city in micro level. It is also playing crucial role in global change study as well as radiation budgets measuring in heat balance studies. The information of LST is very substantial to recognize the urban climatology, ecological changes, anthropological and environmental interactions etc. The Chief motivation of present study focus on time series of ANN model that taken a sequence of LST values of 2000, 2008 and 2016, realize the pattern of variation within the data set and predict the LST values for 2024 and 2032. The novelty of this study centers on evaluation of LST using series of multi-temporal MODIS (MOD 11A2) satellite data by Maximum Value Composite (MVC) techniques. The results derived from this study endorse the proficiency of Geoinformatics Technology with integration of ANN to gain knowledge, understanding and building of precise forecast from the complex physical world database. This study will also focus on influence of Land Use/ Land Cover (LU/LC) variation on Land Surface Temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LST" title="LST">LST</a>, <a href="https://publications.waset.org/abstracts/search?q=geoinformatics%20technology" title=" geoinformatics technology"> geoinformatics technology</a>, <a href="https://publications.waset.org/abstracts/search?q=ANN" title=" ANN"> ANN</a>, <a href="https://publications.waset.org/abstracts/search?q=MODIS%20satellite%20imagery" title=" MODIS satellite imagery"> MODIS satellite imagery</a>, <a href="https://publications.waset.org/abstracts/search?q=MVC" title=" MVC"> MVC</a> </p> <a href="https://publications.waset.org/abstracts/71862/integration-of-artificial-neural-network-with-geoinformatics-technology-to-predict-land-surface-temperature-within-sun-city-jodhpur-rajasthan-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71862.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">240</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">50</span> Thermal Interruption Performance of High Voltage Gas Circuit Breaker Operating with CO₂ Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Babou">Yacine Babou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitesh%20Ranjan"> Nitesh Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Branimir%20Radisavljevic"> Branimir Radisavljevic </a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Seeger"> Martin Seeger</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Over"> Daniel Over</a>, <a href="https://publications.waset.org/abstracts/search?q=Torsten%20Votteler"> Torsten Votteler</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Galletti"> Bernardo Galletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Cristini"> Paulo Cristini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the frame of replacement of Sulfur hexafluoride (SF6) gas as insulating and switching medium, diverse alternative gases, offering acceptable Global Warming Potential and fulfilling requirements in terms of heat dissipation, insulation and arc quenching performances are currently investigated for High Voltage Circuit Breaker applications. Among the potential gases, CO₂ seems a promising candidate for replacing SF6, because on one hand it is environmentally friendly, harmless, non-toxic, non-corrosive, non-flammable and on the other hand previous studies have demonstrated its fair interruption capabilities. The present study aims at investigating the performance of CO₂ for the thermal interruption in high voltage self-blast circuit breakers. In particular, the correlation between thermal interruption performance and arc voltage is considered and the effect of the arc-network interaction on the performance is rigorously analyzed. For the considered designs, the thermal interruption was evaluated by varying the slope at current zero (i.e., di/dt) for which the breaker could interrupt. Besides, the characteristics of the post-arc current are examined in detail for various rated voltages and currents. The outcome of these experimental investigations will be reported and analyzed. <p class="card-text"><strong>Keywords:</strong> <a
