Krishnaiah S. Ramakrishna Reddy M. <p>Study of seepage flow through soil strata of convergent confined aquifer is of complex nature. An attempt has been made to analyse the resistance of fluid flow through convergent duct with dimensions along transverse direction varying from 1000 mm at top and 200 mm at bottom and the height of the duct along longitudinal direction is 1050 mm and width of duct between two parallel confining surfaces is 200 mm filled with porous media of size 14.50 mm crushed rocks for better understanding purpose for certain extent. The total energy loss per unit weight of flowing fluid through boundary of the convergent duct and along the centre of the convergent duct for different bed slopes varying from 60<sup>0</sup> to 90<sup>0</sup> are analysed. The variation of Darcy parameter, a<sub>c</sub>, and non-Darcy parameter, b<sub>c</sub>, which are influenced by the properties of the fluid and porous media, are determined from a plot of i/V versus V along the longitudinal direction of converging duct and along the transfers direction of converging duct are studied to explore the indescribable complex nature of resistance flow through porous media. It is also investigated how the volume flux of fluid is affected when it flows through convergent duct when the media is being packed with porous media with varying bed slopes from 60<sup>0</sup> to 90<sup>0</sup>.</p> 2019-12-26T16:05:16+00:00 Copyright (c) 2019 International journal of Engineering and Innovations Analysis of Roll Cooling System in Hot Strip Mill 2021-04-07T06:59:51+00:00 Srikar Gemaraju <p>Hot Strip Mill (HSM) in Jindal Vijayanagara Steel Limited (JVSL), Toranagallu, Bellary (Dist.), Karnataka is facing a problem such as shorter campaigns, improper strip profile, reduced productivity and increased roll cost. The main cause of these problems is an ineffective work roll and backup roll cooling system for roughing stands. An attempt has been made to design the existing system in terms of number and flow rate of nozzles, nozzle angle and orientation and thermal gradient for various rolling schedules.</p> 2019-12-26T00:00:00+00:00 Copyright (c) 2019 International journal of Engineering and Innovations Comparative Analysis of Decimal Addition Using Different Techniques 2021-04-07T07:01:48+00:00 Haridhar B. Yugesh D. <p>Arithmetic operations of any of the digital devices like Calculator, computers, microcontrollers and other specialized digital systems are on the Base 10 number system only. By Representing these kinds of numbers in BCD the decimal precision applications has DSP, DIP are required in computer arithmetic. An adder for that kind of application must have arithmetic modules that are worked based on coded decimal numbers and data as stored in the similar number format. In this paper, we proposed a decimal adder which is on FPGA based Mixed BCD/excess-6 technique that gives the better performance of decimal adders intended high-end FPGAs. We design adder with help of CLA(CLA), but in this paper, we implement a method decimal adder using carry increment adder (CIA) and to analyzing area and delay are compared with the existing decimal adder. The results of the new decimal adder efficiently improved features like area and delay. There are different types of possible decimal adder circuits, depending upon the code used to perform the decimal digits.</p> 2019-12-01T00:00:00+00:00 Copyright (c) 2019 Qualified Image Watermarking with Approximate Adders Using Xilinx System Generator 2021-04-07T07:02:44+00:00 Reshma Sk. Naga Keerthana Devi E. <p>Image security is playing a key role in present real-world situations as the data transferring is mainly through digital images which may not secure. Hence, we present a novel algorithm for image watermarking using the error recovery adder and discrete wavelet transform. This process involves the hiding of one secret image into the host image qualitatively. For this process error recovery adder (ERA) is used to select the dynamic threshold value from the minimum values of the secret and host image. This error recovery adder reduces delay of the process. This work consists of both embedding and extraction process. The experimental consequences propose that the projected method provide results with high PSNR values.</p> 2019-12-01T00:00:00+00:00 Copyright (c) 2019 Detection of cracks using active thermography for Non-Destructive Testing of Steel Materials 2021-04-26T06:03:29+00:00 Murali Kante Siva Sai Kumar Ande Penchalaiah K. <p><em>Infrared non-destructive evaluation (IRNDE) is an emerging approach for non-contact inspection of various solid materials such as metals, composites and semiconductors for industrial and research interest. This paper focuses on inspection of plain carbon steel materials, which are widely used, particularly in the power and steel industries. This paper describes some applications of recently proposed pulse compression based approach to the inspection of steel specimens. Present work highlights both phase and correlation based approaches for defect detection using frequency modulated thermal excitation scheme and comparison has been made on these proposed schemes.</em></p> 2019-12-26T00:00:00+00:00 Copyright (c)
