<P>We investigated the optical properties of ZnO nanorods on nanosilicon-on-insulator using variable temperature photoluminescence (PL) spectroscopy, and explored the contribution of exciton–phonon coupling and surface resonance effect on the emission characteristics of the nanorods. The low-temperature (<100 K) PL spectra revealed different strengths of exciton–phonon interaction for nanorods of different surface structures. The exciton–phonon coupling strength was stronger for nanorods of rougher surfaces with enhanced contribution of longitudinal optical phonon replicas of free exciton. Despite exhibiting different coupling strengths of exciton–phonon interactions, the room-temperature PL showed an unchanged energy position at 3.28 eV for nanorods of different surface structures. The unchanged energy position of band-edge emission was caused by the competitive effect of the surface defects induced exciton–phonon interaction and the surface resonance effect in faceted nanorods.</P>
Some Common Fixed Point Theorems via Generalized c-Distance
Mohanta, Sushanta Kumar,Maitra, Rima Department of Mathematics 2015 Kyungpook mathematical journal Vol.55 No.1
In this paper, we introduce the concept of generalized c-distance on a cone metric space and prove some common fixed point and coincidence point results by using this notion. Our results generalize and extend several well known comparable results in the literature.
Performance Analysis & Evaluation of ERP: A Case Study of Indian Small Manufacturing Enterprises
Bhagyashree Mohanta,Srikanta Patnaik 한국정보통신학회 2019 2016 INTERNATIONAL CONFERENCE Vol.11 No.1
“Enterprise resource planning (ERP)” refers to a modular and quality software which integrates the principal domains that includes various business activities of an organization into a simplified and integrated system. Acceptance of ERP software in any organization has improved productivity, efficiency and decrease costs in the past. Further it also streamlines the business processes by efficiently improving decision making capability, maintaining employee’s harmony and proper client handling system. In this paper, we have reviewed the implementation benefits, customization, performance evaluation, various success factors and the need of ERP in Small Manufacturing Enterprises (SMEs). This paper also includes the step by step process flow by keeping aimed on performance and cost effectiveness parameters to implement ERP in Indian SMEs to satisfy business needs.

Ensuring the desired degree of cure during manufacturing of vacuum infusion molded (VIM) composite laminateis important to optimize the production time and performance. The traditional method of estimating the degree of cure usingDifferential Scanning Calorimetry (DSC) method cannot be applied during manufacturing. An alternative approach has beenexplored here by embedding Fiber Bragg grating (FBG) sensor and conventional strain sensor in the composite laminateduring manufacturing and mapping the strain developed due to curing with degree of cure. A proper methodology is followedto embed the sensors accurately over glass fiber mats. It is demonstrated that the strain developed during manufacturingindeed indicates different stages of curing cycle. The strain developed can further be mapped with the degree of cure which isestimated by performing a curing experiment using DSC under identical cure conditions as maintained during manufacturing. Thermal Mechanical Analysis (TMA) is also performed to confirm the fact that strain is generated due to shrinkage whichoccurs during the curing process. The initial drop in strain before the crosslinking reaction begins can be attributed to thereduction in viscosity which is further confirmed by the Rheometry analysis. It is established that the time when strain startsto progress and attains a constant value coincides with the onset (tgel) and completion of the curing process respectively.
EXTENSION OF EGERVÀRY THEOREM ON OPTIMAL SOLUTION OF ASSIGNMENT PROBLEM: LOGICAL APPROACH
Susanta Kumar Mohanta,Prasanta Kumar Das 경남대학교 기초과학연구소 2020 Nonlinear Functional Analysis and Applications Vol.25 No.3
A technique to solve the balanced linear assignment problem is introduced using graph theory and is based on logical approach. In the method, the aim is to find a matching in which the sum of weights of the edges is as large as possible, in a weighted bipartite graph. Generally it consists of finding a minimum-weight perfect matching and is a specialization of the maximum weight matching problem for bipartite graphs. The concept of decision matrix ([1]) is applied for finding last two assignments.
Edwards polaron formation : From one to three dimensions
Chakraborty, M.,Mohanta, N.,Taraphder, A.,Min, B. I.,Fehske, H. American Physical Society 2016 Physical Review B Vol.93 No.15
<P>Employing a self-consistent (optimized) variational diagonalization scheme, we investigate the formation of polaronic quasiparticles in a spinless fermion-boson transport model that couples the movement of charge carriers to fluctuations and correlations of a background medium. The background is parameterized by bosonic degrees of freedom. The variational fermion-boson Hilbert space is constructed to achieve high accuracy in one to three spatial dimensions with modest computational requirements. To characterize the ground-state properties of the Edwards model in the single-particle sector, we present exact numerical results for the polaron band dispersion, quasiparticle weight, Drude weight, mass enhancement, and the particle-boson correlations in a wide parameter regime. In the Edwards model, transport will be quasifree, diffusive or boson-assisted in the weakly fermion-boson coupled, fluctuation-dominated or strongly correlated regimes, respectively. Thereby correlated transport is not only assisted but also limited by the bosonic excitations. As a result, the Drude weight remains finite even in the limit of very small boson frequencies. For a strongly correlated background, closed loops are important, in any dimension, to generate a finite effective particle mass even when the free fermion has an infinite mass.</P>
