Get PDFThis paper introduces a novel Bi-directional coupled-inductor (CI) based Γ-Z source converter for step up-step down DC application. It is a modified version of CI based Γ-Z high gain converter. The converter originates under the family of impedance networks with two winding coupled inductor. The said converter when operated with low duty ratio makes converter to achieve high gain compared to conventional DC-DC converters. As the society is in trend with electric vehicles (EV’s) are recommending operating the converters in Bi-directional mode to have continuous power flow when those are operated with green technologies. So, the same converter is initially operated and verified as buck and boost converter in open loop mode. Nearly 38 and 4 voltage-gain in boost and buck mode was observed when realized in MATLAB environment for the designed inductor and capacitor values with 49% and 1% duty cycle respectively under open-loop configuration. In the succeeding a PID controller based closed loop control strategy has implemented for the same converter. Gain sensitivity of the converter had been verified in MATLAB Simulink environment. Results obtained from simulation and mathematical found satisfactory in open and closed loop
A novel single switch controlled efficient coupled inductor-based DC-DC boost converter
Get PDFPollution is one of the most hazard facing in the world. Day by day pollutions has been increased in the society due to population growth, industries, constructions, and transportation. As per the world health organization (WHO) survey, 45% of the air pollution is due to transportation because they lay on internal combustion engine (ICE) based engines. To avoid carbon footprints, green transportation should be encouraged for further generations. In recent days many electric vehicles (EV’s) are found in the market but facing some issues like battery blasts, storage limitations and lack of charging infrastructure. Out of these issues, mainly my focus is on developing a compact, efficient, simple, medium gain coupled inductor-based DC-DC boost converter is proposed which is helpful for fast charging system. In this paper, coupled inductor (CI) and switched coupled inductor (SCI) based converters are designed and analysed with mathematical approach. The outputs of both CI and SCI converters are verified and compared with simulation results and as well CI based converter is developed with hardware prototype and verified hardware and simulation results in terms of gain, elements and efficient

Get PDFOver the decades, several algorithms have been proposed for designing automatic target recognition systems based on synthetic aperture radar imagery. Recently, with the rise of Deep Learning, there has been growing interest in developing neural network based automatic target recognition systems for synthetic aperture radar applications. However, these networks are typically complex in terms of storage and computation which inhibits their deployment in the field, where such resources are heavily constrained.
In order to reduce the cost of implementing these networks, in this thesis we develop a set of compact network architectures and train them in fixed-point. Our proposed method achieves an overall 984× reduction in terms of storage requirements and 71× reduction in terms of computational complexity compared to state-of-the-art convolutional neural networks for automatic target recognition, while maintaining a classification accuracy of >99% on the MSTAR dataset.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01The student, Hassan Dbouk, accepted the attached license on 2020-03-10 at 11:07.The student, Hassan Dbouk, submitted this Thesis for approval on 2020-03-10 at 11:18.This Thesis was approved for publication on 2020-03-11 at 11:49.DSpace SAF Submission Ingestion Package generated from Vireo submission #14893 on 2020-08-25 at 17:26:59Made available in DSpace on 2020-08-26T23:51:24Z (GMT).

No full textHere is a genuine find in this sense: I found it without help on the shelves in this fine bookshop near St. Xavier's College in Kolkata. The picture on the cover, including a fox and some grapes, gave me the clue. It is my first book exclusively in Bengali; I have a bilingual copy of Fox Fables that has both Bengali and English. This book features about a dozen full-page black-and-white designs. Among the best of them are The Ethiopian and CW. I cannot give page numbers because those too are in Bengali! I am proud of finding this book on my busy day in Kolkata!This is a hardbound book (hard cover)Language note: BengaliRetold by Naresh Chandra Jan
In-sensor information processing for resource-limited platforms on flexible epidermal substrates
Get PDFMoving towards the age of big data, the demand for embedded processing has been drastically increasing to make inference and intelligent decisions at lower architectural layers. The myriad of health conditions that can be treated and analyzed via low-energy embedded information processing kernels drives the demand for biomedical circuits, with optimized performance and cost. A large class of these healthcare applications require digital signal processing algorithms to be implemented with strict resources, such as energy and silicon area. Shrinking technology nodes produce both higher computing performance and energy efficiency. However, energy delivery and communication circuitry have not benefited significantly from technology scaling due to different sets of figures of merit. In-sensor information processing can be utilized to lower the energy consumption of such systems by eliminating the redundant volume of data traffic between the sensors and the central processing station. This work focuses on embedding intelligence on the epidermal flexible substrates to extract and analyze critical biomedical information for in-situ diagnosis. The primary objective of this work is illustrating the advantages of epidermal electronics combined with robust information processing systems, at system and application level. The major challenge is the design of robust and efficient algorithms for reliable operation on resource limited hardware platforms and flexible substrate non-idealities. To do so, we developed the first in-sensor ECG and PPG processors on flexible epidermal substrates. The systems are first prototyped using discrete components, followed by an ASIC implementation. Measurement results show that the in-sensor information processing has reduced the transmitted data traffic by 150X, and the system energy consumption by 3.56X.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-12-01The student, Pourya Assem, accepted the attached license on 2016-07-05 at 17:47.The student, Pourya Assem, submitted this Thesis for approval on 2016-07-05 at 17:49.This Thesis was approved for publication on 2016-07-07 at 12:24.DSpace SAF Submission Ingestion Package generated from Vireo submission #9769 on 2017-02-28 at 14:40:24Made available in DSpace on 2017-03-01T17:02:15Z (GMT).
