Objectives: We compared the transbuccal and transoral approaches in the management of mandibular angle fractures. Materials and Methods: Sixty patients with mandibular angle fractures were randomly divided into two equal groups (A, transoral approach; group B, transbuccal approach) who received fracture reduction using a single 2.5 mm 4 holed miniplate with a bar using either of the two approaches. Intraoperatively, the surgical time and the ease of surgical assess for fixation were noted. Patients were followed at 1 week, 3 months, and 6 months postoperatively and evaluated clinically for post-surgical complications like scarring, infection, postoperative occlusal discrepancy, malunion, and non-union. Radiographically, the interpretation of fracture reduction was also performed by studying the fracture gap following reduction using orthopantomogram tracing. The data was tabulated and subjected to statistical analysis. A P-value less than 0.05 was considered significant. Results: No significant difference was seen between the two groups for variables like surgical time and ease of fixation. Radiographic interpretation of fracture reduction revealed statistical significance for group B from points B to D as compared to group A. No cases of malunion/non-union were noted. A single case of hypertrophic scar formation was noted in group B at 6 months postsurgery. Infection was noted in 2 patients in group B compared to 6 patients in group A. There was significantly more occlusal discrepancy in group A compared to group B at 1 week postoperatively, but no long standing discrepancy was noted in either group at the 6 months follow-up. Conclusion: The transbuccal approach was superior to the transoral approach with regard to radiographic reduction of the fracture gap, inconspicuous external scarring, and fewer postoperative complications. We preferred the transbuccal approach due to ease of use, minimal requirement for plate bending, and facilitation of plate placement in the neutral mid-point area of the mandible.
A novel approach for designing of variability aware low-power logic gates
Vijay Kumar Sharma 한국전자통신연구원 2022 ETRI Journal Vol.44 No.3
Metal-oxide-semiconductor field-effect transistors (MOSFETs) are continuously scaling down in the nanoscale region to improve the functionality of integrated circuits. The scaling down of MOSFET devices causes short-channel effects in the nanoscale region. In nanoscale region, leakage current components are increasing, resulting in substantial power dissipation. Very large-scale integration designers are constantly exploring different effective methods of mitigating the power dissipation. In this study, a transistor-level input-controlled stacking (ICS) approach is proposed for minimizing significant power dissipation. A low-power ICS approach is extensively discussed to verify its importance in low-power applications. Circuit reliability is monitored for process and voltage and temperature variations. The ICS approach is designed and simulated using Cadence’s tools and compared with existing low-power and high-speed techniques at a 22-nm technology node. The ICS approach decreases power dissipation by 84.95% at a cost of 5.89 times increase in propagation delay, and improves energy dissipation reliability by 82.54% compared with conventional circuit for a ring oscillator comprising 5-inverters.
Quadratic B-spline finite element method for a rotating non-uniform Rayleigh beam
Vijay Panchore,Ranjan Ganguli 국제구조공학회 2017 Structural Engineering and Mechanics, An Int'l Jou Vol.61 No.6
The quadratic B-spline finite element method yields mass and stiffness matrices which are half the size of matrices obtained by the conventional finite element method. We solve the free vibration problem of a rotating Rayleigh beam using the quadratic B-spline finite element method. Rayleigh beam theory includes the rotary inertia effects in addition to the Euler- Bernoulli theory assumptions and presents a good mathematical model for rotating beams. Galerkin's approach is used to obtain the weak form which yields a system of symmetric matrices. Results obtained for the natural frequencies at different rotating speeds show an accurate match with the published results. A comparison with Euler-Bernoulli beam is done to decipher the variations in higher modes of the Rayleigh beam due to the slenderness ratio. The results are obtained for different values of non-uniform parameter ( n ).
Single-bit digital comparator circuit design using quantum-dot cellular automata nanotechnology
Vijay Kumar Sharma 한국전자통신연구원 2023 ETRI Journal Vol.45 No.3
The large amount of secondary effects in complementary metal-oxide-semiconductor technology limits its application in the ultra-nanoscale region. Circuit designers explore a new technology for the ultra-nanoscale region, which is the quantum-dot cellular automata (QCA). Low-energy dissipation, high speed, and area efficiency are the key features of the QCA technology. This research proposes a novel, low-complexity, QCA-based one-bit digital comparator circuit for the ultra-nanoscale region. The performance of the proposed comparator circuit is presented in detail in this paper and compared with that of existing designs. The proposed QCA structure for the comparator circuit only consists of 19 QCA cells with two clock phases. QCA Designer-E and QCA Pro tools are applied to estimate the total energy dissipation. The proposed comparator saves 24.00% QCA cells, 25.00% cell area, 37.50% layout cost, and 78.11% energy dissipation compared with the best reported similar design.
Pixel-level image fusion techniques in remote sensing: a review
Vijay Solanky,S. K. Katiyar 대한공간정보학회 2016 Spatial Information Research Vol.24 No.4
In the recent years remote sensing image fusion of satellite images has become a popular tool for analyzing different features presented on satellite images. We have analyzed only pixel-level image fusion techniques in this paper, which integrates a low-resolution multispectral (MS) image and high-resolution panchromatic (PAN) image to produce a more informative image than any of the single image. Generally, a PAN image is having a better spatial resolution, while the MS image is having a better spectral resolution than PAN image, due to this trade-off between MS and PAN image resolutions, it could be difficult to preserve spectral and spatial resolution in a single image without a fusion technique. In this paper, we have reviewed most popular and recent image fusion techniques and implemented them on Cartosat-1, RESOURCESAT-2, LANDSAT-8 data set. Results obtained from each method by visual analysis and quantitative measures indicated that UNB fusion algorithm outperforms other techniques used in this paper.

Global trend towards sustainable developments have brought natural, renewable biodegradable raw material into the focus, but due to lack of technical knowhow, only a small fraction of these non-conventional fibres are harvested and utilized. In this study we have developed parallel laid 100% banana nonwoven fabric and cross laid banana/ polypropylene (60:40) nonwoven fabric. Three varieties of banana fibers namely Mahalaxmi, Shrimanti and Graint Naine were used for needle punched non-woven fabric preparations. Analysis of physical properties is carried out in machine direction and cross direction. This paper concludes that cross laid nonwoven fabric show superior tensile properties as compared to parallel laid nonwoven fabric. Shrimanti fibre nonwoven fabric is stronger than Graint Naine and Mahalaxmi fibre nonwoven fabric for both the parallel laid and cross laid structure. Parallel laid Mahalaxmi banana nonwoven fabric and cross laid Graint Naine banana nonwoven fabric gives higher elongation% for machine and cross direction. Increased air permeability of cross laid (60:40) banana/ polypropylene non-woven fabric observed than parallel laid 100% banana non-woven fabric. Parallel laid Graint Naine non-woven fabric showed higher air permeability than Shrimanti and Mahalaxmi parallel laid non-woven fabric. Bursting strength of parallel laid nonwoven fabric is higher, both in the machine as well as in cross direction than cross laid nonwoven fabric for three varieties of banana fibres. Shrimanti banana nonwoven fabric showed higher bursting strength for parallel laid and cross laid structure than Graint Naine and Mahalaxmi parallel laid and cross laid structure.
