Two major challenges are voltage sag & harmonic pollution in the grid. Voltage sag degrades the battery life cycle & harmonic distortion affects the power factor of the grid. This paper proposes a charger model for reducing the impact of voltage sag proposes a design of 6-pulse rectifier charger where a freewheeling diode is used with a capacitor to compensate decreased voltage caused by voltage sag where it can withstand the voltage sag even if the value of it is greater than 0.7 pu. Harmonic pollution is determined by FFT analysis in MATLAB Simulink environment. A C-type high pass filter is designed to reduce harmonics resulting THD factor to improve.","PeriodicalId":427838,"journal":{"name":"2019 2nd International Conference on Innovation in Engineering and Technology (ICIET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115299500","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 nano-scale technology leakage power contributes a large amount of entire power dissipation of a circuit. The main cause of increased leakage power is due to process parameter decrease. Therefore, power dissipation in small devices are now a primary design challenge. Excessive power dissipation can be controlled by reducing supply voltage but that will increase propagation delay. So, we have the dilemma of power and speed in high performance circuit design. A designer must tradeoff between power and speed based on requirement. Multi-threshold CMOS can be an excellent choice to implement in a larger design to achieve most optimum circuit performance. In MTCMOS technology there are low threshold (LVT) CMOS devices & high threshold (HVT) CMOS devices. LVT CMOS can be used where high speed is required while HVT CMOS can be used for low power requirement. In some cases, an optimum design should be a combination of both HVT and LVT. In this paper four widely used D flip flop integrated circuits are taken as examples and analyzed with MTCMOS - LVT & HVT separately. Various performance parameters such as total power, leakage power, propagation delay & leakage power and delay product (PDP) are analyzed. A comparative analysis of power versus delay in four types of D flip flop topologies with MTCMOS are presented afterwards. All the designs are simulated in cadence virtuoso 45nm technology.","PeriodicalId":427838,"journal":{"name":"2019 2nd International Conference on Innovation in Engineering and Technology (ICIET)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126713667","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}

For smart cities, a distributed secure Blockchain-based SDN-IoT architecture has been proposed in this research paper with Network Function Virtualization (NFV) implementation. We have also revolved around the blockchain network which is a highly secured technology that provides good results in network performances, adaptability, privacy, security, accessibility, versatility, confidentiality, and efficiency. Moreover, we have presented a cluster head selection algorithm which aim is to select the desired head of the clusters. In addition, an approach has been also developed that is more efficient for generating a cluster head utilizing SDN-IoT.

The innovative health monitoring systems are required with a less human intervention which will be available at low cost in rural as well as urban areas. This paper describes an idea to provide a cost-effective, reliable and automatic saline flow monitoring system that can be easily implemented in any hospital. The proposed system device consists of Arduino Uno, IR sensor, ESP8266, keypad, LCD.

In BAEC TRIGA Mark II research reactor, power variation is done by manual movement of control rod by operator. This is a very difficult and time consuming process. In this work, we have proposed an automatic control rod movement system for power control in BAEC TRIGA Mark II research reactor. One group first order perturbation theory is used for calculating partially inserted control rod worth in this system. The developed system places control rods in proper position according to desired power level. Without continuous adjustment, the power level will change due to the reactivity feedback of temperature and fission product poisoning. Our system changes control rods’ position according to temperature feedback and reactivity feedback of xenon poisoning. The system has been tested using Proteus simulator for functionality and performance.

These diseases e.g. cardiovascular disease, malignant growth of cancer cells, tumor or Alzheimer’s disease can cause an enormous risk to mankind. In this paper, we attempt to focus on coronary heart disease prediction. Utilizing the Machine Learning (ML) approaches, the coronary disease can be anticipated.
