Neeraj Kumar,Sheifali Gupta 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.5

All over India more than 12 crore people utilize Gurumukhi script for speaking, documenting & other purposes. A considerable advancement in the work associated with the recognition of handwritten and printed Gurmukhi text has been reported in last few years. From the last few decades offline handwritten character recognition has gained a lot of interest of researchers. It is well known that each individual has some different writing style, so it is very difficult to identify or recognize the handwritten characters. Researchers have worked in this field using various scripts like Hindi, English but a very little work has been done in Gurmukhi script point of view. Based on data acquirement process a concise classification of recognition system has been discussed in this article. Various feature mining techniques & classifiers like power arc fitting ,parabola arc fitting, ,diagonal feature extraction, transition feature extraction, K-NN classifier (K-nearest neighbor) & SVM classifier (Support vector machine) are also illustrated in this paper. The methodology for word recognition has also been discussed in this paper.

( Neeraj Kumar Tyagi ),( Bandarupalli Ramesh ),( Kuldeep Tyagi ) 전북대학교 농업과학기술연구소 2009 농업생명과학연구 Vol.40 No.2

Molecular markers are extensively used for improving and sustaining the rice productivity. A variety of molecular genetic markers, including restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNAs (RAPDs), amplified fragment length polymorphisms (AFLPs), microsatellites or simple sequence repeats (SSRs), expressed sequence tags (EST) and single nucleotide polymorphism (SNP) have been developed providing new tools for rice breeding. The major advantages of the molecular markers over the other classes of markers are their number is potentially unlimited, spanning across the genome, their expression is unaffected by the environment and their assessment is independent of the stage of plant development. Molecular markers are landmarks in the chromosome maps that can be used to monitor the transfer of specific chromosome segments known to carry useful agronomic traits. Breeders use these molecular markers to increase the precision of selection for the best trait combinations. Molecular markers have large number of applications ranging from diversity analysis to the improvement of rice varieties by marker assisted selection. This review describes the usefulness of some important DNA markers in rice improvement.

Influence of Hydraulic Distribution Pattern on the Rock Slope Stability under Block Toppling Failure

Neeraj Chaudhary,Subhadeep Metya,Keshav Kumar Sharma 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.4

In this paper, an analytical model for the stability analysis of rock slope subjected to block toppling pertaining to different hydraulic forms has been developed. In the traditional analytical model, ground water pressure is considered to be varied hydrostatically. To better reflect the physical situation, three different hydraulics forms have been considered in developing a stability model for a rock slope susceptible to block toppling. It is well known fact that presence of ground water causes the instability in a rock slope. The present study observes that hydraulic distribution forms also significantly influence the stability of the rock slope. Ground water pressure markedly increases the toppling forces on the blocks and reduces the normal and shear force at the base of block along failure plane, thereby causing instability. The increase in toppling force and reduction in the factor of safety on the blocks are more prominent when the flow slit is blocked, indicating a condition of permanent or seasonal frozen strata. The study highlights that adopting the traditional hydraulic form to analyse block toppling stability, considering presence of ground water would not be suitable for all field conditions. This necessitates the selection of an appropriate hydraulic distribution form based on the encountered field conditions.

Neeraj Dwivedi,Sushil Kumar,Sreekumar C,Saurabh Dayal,C. M. S. Rauthan,O.S. Panwar 대한금속·재료학회 2012 METALS AND MATERIALS International Vol.18 No.2

Diamond like carbon (DLC) thin films with metallic interfacial layers of aluminum and nickel-chromium (Al and Ni-Cr) were grown using a low cost hybrid technique involving a resistive heating thermal evapo-rator and radio frequency plasma enhanced chemical vapor deposition techniques. Stress, hardness, elastic modulus, bonding, phase, and electrical conductivity of these films were investigated. Introduction of interfacial Al and Ni-Cr layers in DLC led to drastic improvement of its conductivity along with a signifi-cant reduction in residual stress but with some reduction of hardness and the elastic modulus. The struc-tural and surface properties of thin films were studied using X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscopy techniques.

Implementation of Arithmetic Logic Unit Using FINFET

Neeraj Jatav,Ayushi Marwah,Shyam Akashe 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.9

Today to complete the extra and difficult task the demand of refining ability of a processor is increasing step by step which resulted in the more fabrication of components fabricated on a single chip as the Moore Law. But with accumulative in a module the noise rises. The ALU is a one of the most important functional units in any CPU. The ALU is a core of any system or any processor as well as the core module of the central processing unit CPU. Since mostly all the simple operations are executed by the support of ALU only. As the name ALU denotes arithmetic logic unit, therefore it is used to execute the arithmetic and logical task in a digital bit. So the ALU can be defined as the combination unit which is used to implement its logical and arithmetic function units. The determination of this paper is to implement the Arithmetic Logic Unit (ALU) by a FinFet technique in 45nm. The work accomplished by ALU is Logic Action (OR, AND and EXOR) and Arithmetic action (ADDER). This result is before certain to the multiplexer and the result obtained is dependent on the input selector line. This result obtained is considered is in the term of average power and noise and paralleled with the dissimilar input value. The application takes domicile in a tool cadence virtuoso. In this paper is to present a modified low power ALU using Fin type field-effect transistors (FinFETs) technique and to compare that with the GDI technique at 45nm.

Thin and Broadband Two‑Layer Microwave Absorber in 4–12 GHz with Developed Flaky Cobalt Material

Neeraj Gill,Jaydeep Singh,Smitha Puthucheri,Dharmendra Singh 대한금속·재료학회 2018 ELECTRONIC MATERIALS LETTERS Vol.14 No.3

Microwave absorbing materials (MAMs) in the frequency range of 2.0–18.0 GHz are essential for the stealth and communicationapplications. Researchers came up with effective MAMs for the higher frequency regions, i.e., 8.0–18.0 GHz,while absorbers with comparable properties in the lower frequency band are still not in the limelight. Designing a MAMfor the lower frequency range is a critical task. It is known that the factors governing the absorption in this frequency predominantlydepend on the permeability and conductivity of the material, whereas the shape anisotropy of the particles caninitiate different absorption mechanisms like multiple internal reflections, phase cancellations, surface charge polarizationand enhanced conductivity that can promote the microwave absorption towards lower frequencies. But the material alone maynot serve the purpose of getting broad absorption bandwidth. With the effective use of advanced electromagnetic techniquelike multi-layering this problem may be solved. Therefore, in this paper, a material with shape anisotropy (cobalt flakes withhigh shape anisotropy) has been prepared and a two-layer structure is developed which gives the absorption bandwidth in4.17–12.05 GHz at a coating thickness of 2.66 mm.

Investigations of Ferroelectric Polarization Switching in Potassium Nitrate Composite Films

Neeraj Kumar,Rabinder Nath 한국전기전자재료학회 2014 Transactions on Electrical and Electronic Material Vol.15 No.2

This article explains the experimental results of ferroelectric polarization switching (FPS) of potassium nitrate (KNO3)with different polymers such as polyvinylidene fluoride (PVDF) and polyvinyl fluoride (PVF) using simple melt-presstechniques. To analyze the ferroelectric polarization switching in potassium nitrate (KNO3) composite films at roomtemperature, we applied the Ishibashi and Takagi theory (based on Avrami model) to the switching current transient. To investigate the dimensionality of domain growth, the ferroelectric polarization switching current (FPS current)was observed from the square - wave bipolar signals across a resistance of 0.1 kΩ in series with the composite films. The existence of a switching current transient pulse confirmed the ferroelectricity and indicated the stability of theferroelectric phase (phase III) of KNO3 at room temperature. Polarization hysteresis (P-E) characteristics supportedthe prominent features of ferroelectric polarization switching in the composite films at room temperature.
