Block-VN: A Distributed Blockchain Based Vehicular Network Architecture in Smart City
( Pradip Kumar Sharma ),( Seo Yeon Moon ),( Jong Hyuk Park ) 한국정보처리학회 2017 Journal of information processing systems Vol.13 No.1
In recent decades, the ad hoc network for vehicles has been a core network technology to provide comfort and security to drivers in vehicle environments. However, emerging applications and services require major changes in underlying network models and computing that require new road network planning. Meanwhile, blockchain widely known as one of the disruptive technologies has emerged in recent years, is experiencing rapid development and has the potential to revolutionize intelligent transport systems. Blockchain can be used to build an intelligent, secure, distributed and autonomous transport system. It allows better utilization of the infrastructure and resources of intelligent transport systems, particularly effective for crowdsourcing technology. In this paper, we proposes a vehicle network architecture based on blockchain in the smart city (Block-VN). Block-VN is a reliable and secure architecture that operates in a distributed way to build the new distributed transport management system. We are considering a new network system of vehicles, Block-VN, above them. In addition, we examine how the network of vehicles evolves with paradigms focused on networking and vehicular information. Finally, we discuss service scenarios and design principles for Block-VN.
Synthesis and characterization of bimodal silver nanoparticles by using semi-batch method
Pradip B. Sarawade,김희택,김상민,김기도 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4
Synthesis of silver nanoparticles stabilized by myristic acids is reported. Bimodal shape of silver nanoparticles was formed by feed rate control using semi-batch method. The synthesized nanoparticles were re-dispersible in solution such as a-terpineol. The a-terpineol solution of these nanoparticles exhibited a surface plasmon resonance in the range around 430 nm. This broad absorption band depicted that the silver nanoparticles have an enhanced stability with increasing chain length of the fatty acid. The size of nanoparticles was influenced by the experimental conditions such as temperature, feed rate and reaction time. The nanoparticles were characterized by TEM, UV and XRD analyses.
APPROXIMATE SOLUTION OF FRACTIONAL BLACK-SCHOLE’S EUROPEAN OPTION PRICING EQUATION BY USING ETHPM
Pradip R. Bhadane,KIRTIWANT P. GHADLE,AHMED A. HAMOUD 경남대학교 기초과학연구소 2020 Nonlinear Functional Analysis and Applications Vol.25 No.2
We proposed a new reliable combination of new Homotopy Perturbation Method(HPM) and Elzaki transform called as Elzaki Transform Homotopy Perturbation Method(ETHPM) is designed to obtain a exact solution to the fractional Black-Scholes equationwith boundary condition for a European option pricing problem. The fractional derivativeis in Caputo sense and the nonlinear terms in Fractional Black-Scholes Equation can behandled by using HPM. The Black-Scholes formula is used as a model for valuing Europeanor American call and put options on a non-dividend paying stock. The methods give ananalytic solution of the fractional Black-Scholes equation in the form of a convergent series. Finally, some examples are included to demonstrate the validity and applicability of theproposed technique.
Some special curves in three dimensional f-Kenmotsu manifolds
Pradip Majhi,Abhijit Biswas 한국수학교육학회 2020 純粹 및 應用數學 Vol.27 No.2
In this paper we study Biharmonic curves, Legendre curves and Magnetic curves in three dimensional $f$-Kenmotsu manifolds. We also study $1$-type curves in a three dimensional $f$-Kenmotsu manifold by using the mean curvature vector field of the curve. As a consequence we obtain for a biharmonic helix in a three dimensional $f$-Kenmotsu manifold with the curvature $\kappa$ and the torsion $\tau$, $\kappa^{2} + \tau^{2} = -(f^{2} +f^{\prime})$. Also we prove that if a $1$-type non-geodesic biharmonic curve $\gamma$ is helix, then $\lambda = -(f^{2} + f').

Sustainability of concrete can be improved by using large volume of fly ash as a replacement of cement and by ensuring enhanced durability of concrete. Durability of concrete containing large volume of class F fly ash is dependent on the design of mixture proportions. This paper presents an experimental study on the effect of mixture proportions on the drying shrinkage and permeation properties of high strength concrete containing large volume of local class F fly ash. Concrete mixtures were designed with and without adjustments in the water to binder ratio (w/b) and the total binder content to take into account the incorporation of fly ash up to 40% of total binder. Concretes, in which the mixture proportions were adjusted for fly ash inclusion achieved equivalent strength of the control concrete and showed enhanced properties of drying shrinkage, sorptivity, water permeability and chloride penetration as compared to the control concrete. The improvement of durability properties was less significant when no adjustments were made to the w/b ratio and total binder content. The results show the necessity of the adjustments in mixture proportions of concrete to achieve improved durability properties when using class F fly ash as a cement replacement.
Adaptive Radio Resource Management Algorithm for MIMO-OFDMA System
Pradip Paudyal,Laszlo Pap,Andras Gabor,Sharad K. Chimire 한국멀티미디어학회 2010 한국멀티미디어학회 국제학술대회 Vol.2010 No.-
A real time QoS aware adaptive radio resource management algorithm for downlink of multi-cell and multi. user MIMO-OFDMA system is presented. This proposed scheduling algorithm takes into account queue status, transmission rates, channel state information and priority of the user for subcarrier, power and bit allocation in MU-MIMO-OFDMA system. Subcarrier selection is based on the priority of the user and eigenvalue product criterion and "water-filling algorithm" is adapted for bit loading and power allocation problem. Simulation results show that this algorithm can not only increase the data rate of the system, but also QoS of the user. This algorithm can able to maintain required QoS for each user.

Effect of addition of municipal solid waste compost(MSWC) on lead (Pb) content of submerged rice paddies wasstudied. Experiments were conducted during the three consecutivewet seasons from 1997 to 1999 on rice grown under submergence,tial extraction method was used to determine the Pb fractions inMSWC and decomposed cow manure (DCM). Lead was signifi-cantly bound to the organic matter (60%) and Fe and Mn oxidesin MSWC and DCM. Lead content (mg kg-1) in rice straw washigher than in rice grain. Lead bound with water soluble andexchangeable fractions in MSWC and DCM was best correlatedwith straw and grain Pb. Fe and Mn oxide bound Pb in both theorganics also significantly correlated with straw and grain Pb con-Pb in MSWC and DCM did not significantly corelate with Pbcontent in rice straw and grain metal. MSWC would be a valuableresource for agriculture if it can be used safely, but long-term fieldexperiments with MSWC are needed to assess by regular moni-toring of the metal loads and accumulation in soil and plants.
