An Improved Optimization Technique for Energy Harvesting System with Grid connected Power for Green House Management

Rajaram A.,Sathiyaraj K. 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.5

In recent days, the electricity demand is increased day by day. For reducing this fact, various sustainable resources are used. The sustainable sources used with grid-connected power for supplying external power to the user. Green house harvesting system makes the effi cient harvesting and those are far from locality and off shore aqua farms. Conventional method uses wireless sensor network and RFIDs. This increased the design complexity and also increases the power loss. The existing optimization method used in this application is that Stochastic Tunnelling Particle Swarm Optimization Technique (ST-PSO). Novelty of this work implemented to enhance the performance by quantum tunnelling PSO on energy harvesting system and the hybrid resource always supply the power to the grid. Here the proposed research works on grid connected harvesting model extracts the energy from solar array and electromagnetic waves with RECTENNA. Here the rectifying antenna used to convert electromagnetic waves into the electrical energy and the PV generates power by changing irradiance and temperature. Here the optimization technique uses the Quantum Tunnelling Particle swarm optimization (QT-PSO) algorithm, which is eff ectively performed in PV based applications. This quantum tunnelling method is to converter the electromagnetic wave into DC power source, which is given to the grid-connected power generation circuits and it optimizes the result of energy harvesting system. The grid connected power system is used to supply the power without loss. Therefore, the proposed energy harvesting system is better than conventional systems by reducing power loss. The proposed research work is implemented in MATLAB and the model is done by SIMULINK.

Controlled repeated chemical growth of ZnO films for dye-sensitized solar cells

Rajaram S. Mane,이원주,C.D. Lokhande,조병원,한성환 한국물리학회 2008 Current Applied Physics Vol.8 No.5

The controlled growth of ZnO nanorods perpendicular to substrate surface i.e. c-axis by a repeated chemical deposition method for efficient dye-sensitized solar cell application is described. X-ray diffraction study shows the wurtzite structure of ZnO with high crystallinity. Intensity and newly evolved peaks of the ZnO are found to be thickness dependent. Dye loving flower-like globular architecture of ZnO is observed after 8 lm thickness. Dye-sensitized solar cell studies show the solar-to-electrical conversion efficiency of 2.21% for 11 lm ZnO electrode when illuminated with 80 mW/cm2.

Poster Session : PS 0426 ; Infectious Disease ; Late Presenters to HIV Care in the Era of Free Antiretroviral Therapy

( Rajaram Deepak Madi ),( Sathish V ),( Basavaprabhu Achappa ),( Sathish Rao ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: Highly active antiretroviral therapy (HAART) is available free of cost in India as a part of our national ART programme since 2004.Early diagnosis and initiation of HAART are key components for the success of HIV control programmes. Late presentation with low baseline CD4 cell count is a strong prognostic marker for early mortality among HIV patients. The main aim of our study was to identify late presenters based on initial CD4 cell count testing. We also wanted to identify factors associated with late presentation. Methods: This retrospective hospital based study was carried out at Kasturba Medical College. The study group included 474 newly diagnosed HIV patients registered in the ART clinic of KMC between February 2012 and February2013. Subjects with CD4 T cell count below 200 cells per cubic millimetre were classifi ed as late presenters. Subjects with CD4 T cell counts less than 50 cells per cubic millimetre were termed as very late presenters. Statistical analysis was performed with SPSS software. Results: The mean age of our study population was 41.60±9.28years. Majority of our study population were males 327(69%). Median CD4 count at diagnosis was 188 cells per cubic millimetre ([IQR] 93-366 ). 208(44%) patients had WHO stage 4 disease at presentation. 251(53%) were late presenters and 223(47%) were early presenters. 47(9.9%) were very late presenters.Male gender(p=.03) and residing in rural area (p=.001) had a signifi cant positive association with late presentation. Conclusions: More than fi fty percent of patients were late presenters despite ART being available free of cost in India. Late presentation poses a signifi cant threat to the success of our national ART programme.HIV/AIDS care intervention programmes must target men and the rural population as they are vulnerable for late presentation as shown in our study.

Should Japan go Nuclear?

( Rajaram Panda ) 한국국방연구원 2014 The Korean Journal of Defense Analysis Vol.26 No.4

In view of the changing security environment in Northeast Asia, stemming from China’s assertiveness in regional issues and North Korea’s nuclear weapons program, the threat perception in Japan has considerably heightened. This has triggered a debate domestically in Japan about whether it is an appropriate time to review its nuclear option as a means of deterrence. Such thinking presupposes that confidence in the U.S. extended deterrence has started eroding or has weakened. There are various political strands to this issue and there is no consensus yet reached to make the change officially possible. If Japan does indeed initiate a change in policy seriously, it would make the United States uncomfortable. But given the strong anti-nuclear sentiment in Japan, it would be difficult for any government of any party to sell the idea to the people. The domino effect of such a policy change would be seen almost immediately in South Korea and Taiwan, making Northeast Asia the world’s most nuclearized region. This would also mean the abrogation of the security alliance relationship with the United States. Given Japan’s capability in terms of capital, technology and possession of sufficient spent fuel needed for making the nuclear bomb it would be possible for Japan to make a nuclear bomb, but it would be a politically dangerous move and therefore inadvisable. Though it would remain theoretically possible, the debate would remain as an academic exercise for quite some time. This essay makes an attempt to study this complex issue as objectively as possible.

Non-Linear Error Identifier Algorithm for Configuring Mobile Sensor Robot

Rajaram.P,Prakasam.P 대한전기학회 2015 Journal of Electrical Engineering & Technology Vol.10 No.3

WSN acts as an effective tool for tracking the large scale environments. In such environment, the battery life of the sensor networks is limited due to collection of the data, usage of sensing, computation and communication. To resolve this, a mobile robot is presented to identify the data present in the partitioned sensor networks and passed onto the sink. In novel data collection algorithm, the performance of the data collecting operation is reduced because mobile robot can be used only within the limited range. To enhance the data collection in a changing environment, Non Linear Error Identifier (NLEI) algorithm has been developed and presented in this paper to configure the robot by means of error models which are non-linear. Experimental evaluation has been conducted to estimate the performance of the proposed NLEI and it has been observed that the proposed NLEI algorithm increases the error correction rate upto 42% and efficiency upto 60%.

Design of Mobile Sensor Robot using Non-Linear Fault Recognizer Algorithm

Rajaram.P,Prakasam Periasamy 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

For tracking the large scale environments, Wireless Sensor Network is an efficient tool. In such environment, restriction of battery life of the sensor networks is done because of the grouping of data, utilization of sensing, computation and communication. To determine this, a mobile robot is designed to recognize the data exist in the separated sensor networks and moved on to the sink. In new data collection technique, the outcome of the data grouping process is minimized as mobile robot can be employed in the restricted range. To improve the data collection in a varying environment, Non Linear Fault Recognizer (NLFR) algorithm has been introduced and designed in this paper to construct the robot using fault models that are non-linear. Experimental evaluation has been performed to calculate the outcome of the proposed NLFR and it has been examined that the proposed NLFR algorithm improves the fault correction rate upto 25% and efficiency upto 57%.
