Airline networks in particular have significantly lowered the spatial and time limits on moving people, goods, and information-all of which are becoming more and more critical elements for the information economy. Therefore, regions are more concerned with the quantity and quality of airline connections. The goal of this study is to examine the global airline network connectivity hierarchy that is now developing, based on the air routes that are connected to important airports all over the world by building an air transportation network. Network analysis is done using lobby index to uncover the robustness of air transport networks while facing random errors and intentional attacks which is an important area of research in the field of transport geography. Also, a criterion to check whether strength of ties between various cities can significantly impact the assessment of local influence and lobbying power of various geographical areas is devised.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114808030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a heat exchanger system, the transfer of heat from a hot fluid to a colder one is maintained by adopting a cascade control structure. The main objective of this work is to maintain the temperature of the shell outlet. The cascade control structure is designed for controlling the temperature in which the inner loop contains a flow controller that controls the flow rate of the tube outlet. STHE system is modeled to a first order plus dead time (FOPDT) system for the inner loop (controlling the flow rate) as well as for the outer loop (controlling the temperature). The inner loop is controlled by a PI controller while the outer loop is controlled by a PID controller. The controllers are designed based on the frequency domain specifications such as gain margin and phase margin to attain the desired control output. The proposed controller can achieve the desired values of temperature irrespective of external disturbances and parameter uncertainties.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128196073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This accounts for having a better performance of the vehicle. Hence estimating the performance and behavior of the electric vehicle components reduces testing time and cost and makes it more efficient. The development of an Electric Vehicle powertrain and the control algorithm of the motor is intended. The specifications and parameters of a commercially available electric vehicle were analyzed and its powertrain dimensions were decided as the benchmark parameters. A complete model of the dimensioned powertrain and its control algorithm will be simulated in the Simulink environment and analyzed. The control algorithm for the motor will be uploaded onto a commercially available motor controller and the performance, and efficiency of the algorithm will be analyzed on a virtual motor and vehicle model using the processor in loop feature (PIL) of MATLAB Simulink. The objective is to study and develop an EV powertrain in Matlab/Simulink environment and to compare the performance of the designed powertrain and its control algorithm with that of existing benchmarks. The system gives various performance parameters of the electric motor and the battery pack by taking the drive cycle as the input.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124815782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It helps to capture public opinion and user interests on various topics based on comments on social events, product reviews, film reviews, etc. Linear Regression, Support Vector Machines, Convolution Neural Networks (CNN), Recurrent Neural Networks (RNN), LSTM (Long Short Term Memory), and other machine learning and deep learning algorithms can be used to analyze the sentiment behind a text. This work analyses the sentiments behind movie reviews and tweets using the Coronavirus tweets NLP dataset and Sentiment140 dataset. Three advanced transformer-based deep learning models like BERT, DistilBERT, and RoBERTa are experimented with to perform the sentiment analysis. Finally, the performance obtained using these models on these two different datasets is compared using the accuracy as the performance evaluation matrix. On analyzing the performance, it can be seen that the BERT model outperforms the other two models.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133510051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spacecraft moving from an higher orbit to a lower orbit using a solar electric propulsion system posses a major challenge of long transfer time and degradation of solar array in Van Allen belt. The mathematical formulation of spacecraft used earlier for orbit raising is implemented for orbit lowering to bring the spacecraft to a lower orbit to reach the Earth's atmosphere and burn by optimizing the angular momentum and eccentricity to that of target orbit. This phenomenon is divided into many unconstrained sub-problems of optimization which perform the deviation gap minimization between geosynchronous equatorial orbit and a lower orbit.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"388 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131817342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this way, the CAN bus is a fundamental component of intra-vehicle communication. The CAN bus was designed without focusing on communication security and in this way it is vulnerable to many cyber attacks. As the vehicles are always connected to the Internet, the CAN bus is remotely accessible and could be hacked. To secure the communication between ECUs and defend against these cyber attacks, we apply a Hash Message Authentication Code(HMAC) to automotive data and demonstrate the CAN bus communication between two ECUs using Arduino UNO and MCP2515 CAN bus module.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132358288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current-voltage characteristic of the power supply is adjusted according to the photovoltaic array model due to the injection of current into the junction of the feedback voltage divider circuit through an additional resistor. NI data acquisition device and Lab View software are used to build the emulator control system. The photovoltaic array model was implemented into the software algorithm as a look-up table to reduce the processing time and improve the system response. An “off-the-shelf” switching mode power supply having the flyback architecture and 230V ac input was selected for the practical experiment.

However, the main disadvantage related to this configuration is the high windage loss generated at the air-gap due to the viscosity of the fluid, which can result in very high temperatures on the rotor surface and drag forces on the rotating components. This required an accurate prediction of windage losses to estimate the reduction in mechanical output torque and to evaluate exactly the heat generated on the rotor surface, which can cause a series of problems like the demagnetization of the magnet in PM machines. Also to accurately estimate the machine's performance. Therefore, this paper investigates the impact of machine design parameters on the windage losses generated inside the airgap of high speed machines, and the resulting variations in the machine efficiency are presented and described. Both theoretical and finite element modeling have been used in the analysis.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128883873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The maritime industry is part of the vectors able to influence significantly emissions of greenhouse gases. In fact, the maritime industry moves more than 80% of the World trade by volume, which makes it a large and growing source of global greenhouse gas emissions contributing to climate change. The Ships are also a source of pollution to the local communities living near the Ports due to their energy consumption when at berth. At the current date, the most common method to mitigate this problem is to provide the ships at berth electricity from shore side. This paper presents the project greenPORT, which aims to create an energy management system for a green energy Port. After a brief introduction, the state of the art and relevant standards related to shore power and green ports are discussed and then, a Port load curve model is presented. This load model, built through a statistical analysis of real data from the Port of Lisbon from the year of 2019, will form the backbone of a future green port management system.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127601923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
