Authors: Uppal, Harita
Abstract: This project aims to develop the maximum power point algorithm for the system. The system is
tested for both traditional and the artificial intelligence algorithm. The traditional algorithms are
implemented in the the MATLAB function block and is tested in the Simulink of MATLAB. Two
types of traditional algorithm are implemented in the system that is Perturb and observe method
and the incremental conductance algorithms.
Their performance evaluation in terms of efficiency is done. Then three
algorithm Lavenberg Marquardt, Bayesian Regularisation and scaled conjugate is implemented in
the system Their performance characteristics in terms of mean square error, regression , efficiency
is done. The parameter to be optimized is number of hidden layer. Other parameters like type of
transfer function and the type of network can be optimized in the nn tool of MATLAB. The Neural
Network fitting app is used in the system. And the algorithms is used in the system using the
application. And the results for the algorithm is concluded at the end of the report2019-05-01T00:00:00ZGEANT4 SIMULATIONS ON OPTICAL PHOTONS IN SCINTILLATORSPaunipagar, Mayurhttp://localhost:8081/xmlui/handle/123456789/155822023-07-14T11:57:44Z2019-05-01T00:00:00ZTitle: GEANT4 SIMULATIONS ON OPTICAL PHOTONS IN SCINTILLATORS
Authors: Paunipagar, Mayur
Abstract: Calculation of no. of optical photons produced in a scintillator due to absorption of nu-
clear radiation has widespread use in various applications such as gamma spectroscopy, Single
Photon Emission Tomography (SPET), Positron Emission Tomography(PET), etc. One of
the important properties of scintillation detector is its energy resolution. GEANT4 simulation
toolkit is the an e ective platform where one can simulate gamma photons and also production
of optical photons which provides information about the energy resolution. In this project,
GEANT4 toolkit is used to simulate the production of optical photons in scintillators in order
to understand the e ect of shape of scintillator on the energy resolution of scintillation detector
for gamma rays.2019-05-01T00:00:00ZTiO2/Bi0.7La0.3 FeO6 (BLFO) HETROSTRUCTURE THIN FILM FOR PHOTOVOLTAIC APPLICATIONSChaudhary, Rashmihttp://localhost:8081/xmlui/handle/123456789/155812023-07-14T11:57:30Z2019-05-01T00:00:00ZTitle: TiO2/Bi0.7La0.3 FeO6 (BLFO) HETROSTRUCTURE THIN FILM FOR PHOTOVOLTAIC APPLICATIONS
Authors: Chaudhary, Rashmi
Abstract: Multiferroic are materials which exhibits more than one ferroic orders and magnetoelectricity,
refers to coupling between magnetism and electricity. BLFO was prepared by solid state reaction
method. In the present work, rare earth element 30% La is doped in BiFeO3 and TiO2 thin film
heterostructure deposited on Ti coated Si substrate by pulse laser deposition (PLD) technique.
The structural, electrical, optical and photovoltaic property of TiO2/BLFO structure has properly
investigated. The BLFO thin film characterization has done by X-ray diffraction (XRD), Field
emission scanning electron microscopy (FE-SEM), Energy dispersive analysis of X ray(EDAX),
Impedance analyzer for dielectric measurements, Atomic force microscopy (AFM) and Solar
simulator. From morphological characterization it found the grain size increases of BLFO and
TiO2 / BLFO thin film. Dielectric constant increases by increasing grain size and this shows
Polarization in ferroelectric. The hetrostructure of TiO2/BLFO shows significant photovoltaic
effect and having efficiency 0.13% under illumination2019-05-01T00:00:00ZSTUDY OF COMPTON ELECTRONS IN HALIDE SCINTILLATORS USING CCTKaintura, Sanjeet Singhhttp://localhost:8081/xmlui/handle/123456789/155802023-07-14T11:57:18Z2019-05-01T00:00:00ZTitle: STUDY OF COMPTON ELECTRONS IN HALIDE SCINTILLATORS USING CCT
Authors: Kaintura, Sanjeet Singh
Abstract: Cerium doped Lanthanum halide scintillators are applicable in gamma ray spectroscopy and other applications on a vast scale due to their excellent energy resolution and high stopping power. Present work is based on a technique which is well known as Compton Coincidence Technique (CCT). It was proposed by Valentine and Rooney in 1994, to measure the intrinsic energy resolution of scintillating material. We measured the intrinsic resolution of Compton electron in 3 different scintillators, namely, 1″ × 1″ cylindrical Lanthanum halides (LaBr3:Ce, LaCl3:Ce) and 2"×2" NaI:Tl detector with HPGe as a reference detector. Intrinsic energy resolution was measured by the advanced digital data acquisition system PIXIE-4 which makes the whole measurement setup quite compact having inbuilt spectroscopic amplifier. To measure the intrinsic energy resolution of these scintillators, we have employed the Wide Angle Compton Coincidence Technique (WACCT) for an energy range from 45 keV up to 1.33 MeV. The obtained results shows that nonproportionality is a major reason of entire energy resolution of these halide scintillators and intrinsic resolution mainly arises due to scattering of electrons inside the scintillators. The effect of variation of energy resolution with energy gating width was also measured to optimize its value for a particular detector2019-05-01T00:00:00Z
