In this paper a forensic process model is proposed which considers possibility of multiple parallel event sequences that must be considered to achieve correctness in event reconstruction in digital forensic investigation. Towards this end, use of Event Sequence Graph (ESG) as a directed graph for outlining events and the sequences which they follow has been proposed by the authors. Two case studies of attack from multiple sources have been used as examples to explain the type of scenarios which could be easily understood using an ESG.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114681217","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 design, simulation and fabrication of two linearly polarized 2 × 1 and 2 × 2 element microstrip array has been done and comparison is made in terms of different antenna parameters like radiation pattern, return loss, VSWR (voltage standing wave ratio), reflection co-efficient, gain and %bandwidth.

In this work, we propose a stereo vision based methodology for the purpose. The work relies on disparity map. First of all, pixels with the same disparity in the continuous space form the components. Detected components are then filtered based on size and density criteria. Finally, the filtered components are combined based on adjacency, connectivity strength and depth proximity. Thus, 2D object proposals are obtained and mapped to 3D bounding boxes. A dataset has been prepared to test the methodology. Performance has been compared with another system developed by Computer Vision Lab at INHA University, Incheon, South Korea. It is observed that the detection capability of the proposed system is superior. Furthermore, the computational speed makes the work suitable for robotic applications such as SLAM.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122295480","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}

So, this article introduces a grasshopper optimization algorithm (GOA) based fuzzy PD-PI cascade controller for the LFC study considering a three area interconnected system. Initially, each area of the interconnected power system comprising of a thermal generating unit and further to show the impact of renewable energy sources (RES), a combination of wind generating unit and the solar-thermal generating unit is incorporated along with thermal generating unit in area-1. The study begins with the performance verification of the GOA technique over other techniques. Then to get sure about the selection of objective function, the performance of the GOA-PI controller has been verified by considering two mostly used objective functions i.e. integral time multiplied absolute error and integral square error. Lastly, the performances of the proposed controller have been verified over other controllers for the system with/without incorporating RES.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128756398","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 paper the battery charging scheme for EV has been proposed by using bidirectional AC/DC converter and a bidirectional DC/DC resonant converter. Here bidirectional power flows from Grid to Vehicle and Vehicle to Grid. The proposed scheme operates in two modes: Charging and Discharging of the storage battery where each mode has two stages. The charging mode converts 230V, 50Hz grid supply into 410 V DC with a bidirectional AC/DC converter. At the second stage rectified voltage steps down to 120V with the help of a bidirectional resonant DC-DC converter to charge an onboard 120 V, 10AH battery. The direction of power flow reverse during discharge. The battery voltage boosts up to 410V by a bidirectional resonant DC-DC converter and then this output voltage is fed back to the grid with a help of the bidirectional DC/DC converter. The resonant converter operates with 40kHz switching. The soft switching technique ZCS/ZVS help to minimise the switching losses and reduce the size of the components. The AC/DC converter has been simulated with SPWM technique. The overall concept has been simulated in Simulink/MATLAB.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126453378","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}
