Published: June 2020

Abstract
Various relaxation procedure in the supercooled state of D-xylose have been investigated using dielectric spectroscopy over a wide frequency (1 mHz – 10 MHz) and temperature range (140-350 K). The main relaxation process (α) that is accountable for the glass transition phenomena, another secondary relaxation process is also visible below glass transition temperature. The attached hydroxymethyl (-CH2OH) side group to the sugar ring might be responsible for this process. In addition, we have applied Coupling model to find the location of intermolecular relaxation below the glass transition temperature (Tg). The dependence of various dielectric parameters viz. τα, τβ, τγ and τβ cm on temperature have been critically examined. The current experimental result shows that, log10 σdc vs. log10 τα dependence is nonlinear and hence can be described with the fractional Stokes-Einstein-Debye relation.

Abstract
The current paper examined the impact of Cu2+-Cr3+ substitution on the structural and dielectric possessions of nanoparticles of cobalt ferrites with the composition Co1-xCuxFe2-xCrxO4 (x=0.0, 0.1, 0.2), synthesized via sol-gel auto-combustion technique and calcinated for 4 hours at 700°C. The XRD patterns display large peaks suggesting nanocrystalline for inverse spinel ferrite formation. FTIR indicate the formation of spinel ferrites by revealing the presence of a typical absorption band in range 390-410 cm−1 and 540-560 cm−1, respectively. FESEM reveals that the specimen is plate and sponge-like structure. In the frequency assortment 1 KHz -5 MHz, dielectric analysis at room temperature was performed and described on the foundation of the phenomenological theory of Koop and the theory of Maxwell Wagner. The result shows the highest dielectric constant without doping is 128.5. The experiment showed low dielectric loss i.e. 1.8 with x=0.2.

Authors: Sinha Subhojyoti , Meikap Ajit Kumar 
Published: June 2020

Abstract
The temperature dependent current-voltage characteristics of the Polyvinyl Alcohol-Zinc selenide nanocomposite films were studied in the voltage window of -5V to +5V. It was observed that with the increase in applied voltage and temperature, the current-voltage characteristics shift from ohmic to non-ohmic nature and show hysteresis behavior. It has also been observed that the sample resistance changes from low resistance state (LRS) to high resistance state (HRS) depending on the applied voltage and temperature. The observed phenomenon has been analyzed based on the available theoretical models to elucidate the prevailing current conduction mechanism.

Published: June 2020

Abstract
Comprehensive quality assurance (QA) and beam data acquisition has been performed for commissioning of Varian Trilogy linear accelerator for stereotactic radiosurgery (SRS). Mechanical, electrical and radiological tests were performed to check linac performance as per American Association of Physicists in Medicine (AAPM) Task Group (TG) 142. The geometric isocentre accuracy, congruence check and calibration of kV and MV imager were performed using the Isocal QA device. The off axis ratio profiles, depth dose data and beam output factors of 6 MV SRS beam for the field sizes ranging from 2 × 2 cm2 to 15 × 15 cm2 were measured using SFD diode detector and cc13 semiflex ion chamber. The multileaf collimator (MLC) characterization was done in the treatment planning system (TPS) using the parameters measured with the CC13 semiflex ionisation chamber in water phantom. Dose measured with 2D ion chamber array was compared to that calculated in TPS. The maximum change in MV and kV imager isocentre was within ±0.03 cm. The variation between SFD measured and ion chamber measured beam data is in positive correlation for fields sizes down up to 2 × 2 cm2. Variation in output factors is ±0.56 ± 0.05 %. The measured beam data is imported and calculated in the Eclipse TPS and is found within 1% gamma agreement index (GAI) with the Analytical Anisotropic Algorithm (AAA) model data. GAI for TPS verification QA is 97.8%, 98.5% and 98.3% respectively for fix jaw 2 × 2 cm2, 5 × 5 cm2 and rapid arc SRS plan. Successful modelling of the photon beam for high dose rate SRS mode is achieved for clinical treatment of patients.
Ultrasound-based Classification of Fatty Liver Disease: A Review
Authors: Sharma V , Juglan K C 
Published: June 2020

Abstract
Hepatic steatosis synonymous with fatty liver is a disease that results from excess fat in the liver. It's normal to have small amounts of fat in the liver, but too much can drag into a health issue. It is such a disease, which may lead to loss of human life, if not cured at an early stage. To detect such a disease highly precise and reliable technique is required such as ultrasound imaging. Different CAD frameworks have been proposed, to categorize the images as normal and fatty liver ultrasound images. Classifying the images with the assistance of the CAD systems developed till date is not found to be up to the mark. The sensitivity and accuracy measurements values still need improvement. Although much research has been carried out in this area, it is the subject of great significance due to increasing prevalence of fatty liver across the globe. In therapeutic imaging and diagnostic radiology, CAD has ended up a standout amongst the most important research topic. It introduces the pattern recognition software that analyse suspicious features on the image and help the radiologists to solve the problem. Over the past years, booming research has been done on classifying liver ultrasound images. This paper presents the recent trends in Ultrasound-based classification of various liver diseases through Computer Aided Diagnosis systems and the current challenges and future directions to improve the diagnostic accuracy.

Authors: Dev Ajay , Goel Anshika , Prasher Sangeeta , Kumar Mukesh 
Published: June 2020

Abstract
Variations in crystalline structure, optical property, structural bonding in Graphene Oxide (GO) doped polypyrrole (PPy) under gamma irradiation at 100 KGy with effective dose rate of 2.86 KGy per hour have been studied. The crystalline structure has been studied utilizing XRD spectroscopy and it has become clear that as compare to non-irradiated, irradiated sample show more shift toward crystalline nature, this is because of the decrease in d -spacing. The variation in optical properties have been evaluated using UV-VIS spectroscopy, it has been pointed that gamma irradiation reduces the optical band gap due to the chemical reactions, such as chain scissioning etc., induced by gamma exposure, this result is further supported by FT-IR spectroscopy.

Published: June 2020

AbstractHigh resistivity (or low electrical conductance values) materials have found their applicational foot in those domains of electrical-electronical where resistors, heat filaments, space heaters, shunt resistors electric irons and etc. are broadly exercised on. This paper investigates the effect of addition of polyaniline (PANI) on the properties of copper (II) oxide (CuO) nanoparticles. Sol-Gel method was used to synthesize CuO nanoparticles while PANI was obtained by oxidative polymerization process. The structural characterizations of the composite material and the effect of PANI on the CuO nanoparticles are studied through FESEM, XRD, FTIR and Raman Spectroscopy. XRD confirmed the formation of CuO without the presence of CuO2. FESEM showed the clear formation monoclinic structure of CuO. EDX revealed that Cu and O-atoms are in stoichiometry, thus confirming the formation of CuO bond and peaks of C, N and O are also obtained depicting the PANI formation. The characteristic peaks are obtained for both CuO (402.99-678.74 cm−1) and PANI (1109.94-1568.54 cm−1and 3058.81-3436.21 cm−1) through FTIR. The Raman analysis of CuO sample showed 3 peaks (290.01 cm−1, 333.51 cm−1and 624.81 cm−1) and while PANI showed peaks in the range from 1166.48 cm−1– 1582.81 cm−1. The dielectric properties were investigated using Maxwell-Wagner model and Koop’s phenomenological theory. The fore-mentioned composite material can also be considered to be devised in a resistor.
Influence of gamma radiation on PVC/PANI composites
Authors: Sharma S , Prasher S , Singh K L , Kumar M 
Published: June 2020

Abstract
PVC/PANI composites radiated with 75KGy of Gamma radiations were studied for their modifications in optical and structural properties as compared to the pristine polymer composites. The study of FTIR spectra of gamma radiated and pristine samples of polymer composite shows that the intensity of peaks decreases with gamma irradiation and at the same time shifts towards lower wave-number for pure PVC and its composites. It is further found that the water content has been reduced with Gamma irradiation and CO2 was released. The UV-VIS spectra for PVC/PANI composites were studied after irradiation with 75KGy of Gamma radiation and compared with the pristine composites. It was observed that the direct band gap, indirect band gap and urbach’s energy increases with gamma irradiation for pure PVC which may be attributed to increased cross linking in PVC due to irradiation. For other concentrations of PANI in composite the direct band gap, indirect band gap and urbach’s energy is found to decrease with irradiation. PL studies of composite showed that with the addition of PANI the colour of emission has been found to shift towards yellow. After irradiation the emission colour has been found to shift towards white colour where as negligible effect has been found for composites with higher concentration of PANI.

Authors: Kaur Parminder , Singh K J , Thakur Sonika 
Published: June 2020

Abstract
Proper shielding from harmful ionizing radiations is a mandatory requirement in nuclear facilities owing to the harmful effects on radiation workers and general public in case of radiation exposure. The present work is aimed at the investigation of the shielding properties of the prepared glass system of chemical composition (83.5+x)Bi2O3-(0.6+x)Li2O-0.1MnO2-(15.8-2x)B2O3 (with x = 0, 0.7 and 1.4 wt.% coded as L5, L10 and L15 respectively), with respect to the Gamma-ray, Beta and fast neutron radiation. The Gamma-ray shielding property of the glass system was also compared with the most commonly used Barite concrete and commercially available shielding glass ‘RS 253 G18’. Also, the neutron shielding properties was compared with common neutron shielding materials including Graphite, Boron Carbide and Polyethylene grains. An attempt was made in this study to select a better shielding material than the compared standard shielding materials. It is inferred that L15 glass sample is the best shield material for Gamma-rays, fast neutrons and also, for Beta radiation in the high energy region due to Bremsstrahlung, while in low energy region glass, L5 is better for Beta shielding.

Published: June 2020

Abstract
in this paper, spherical silica nanoparticles were doped into a ferroelectric liquid crystal (FLC) material. Dielectric studies were carried out in the frequency range of 20Hz-1MHz. Temperature and frequency dependent dielectric permittivity were investigated in the undoped and doped samples. It was observed that adding a small amount of SNPs, the permittivity increases ∼20% than pure FLC mixture. A Goldstone mode was observed in both pristine FLC and SNPs doped FLC samples. The relaxation frequency of detected mode was also observed at ∼570 Hz and ∼715 Hz for pristine FLC and doped samples respectively at 34°C. A single relaxation behaviour was also described in the form of Cole-Cole plot.

(where β, k are constants). We got the cosmological models in which the Universe begins from a non-solitary state and grows exponentially with infinite time t till late occasions. The deceleration parameter in the model is observed to be time subordinate. The deceleration parameter in the model is found to be time dependent. It is seen that this parameter shows the development from initial decelerating period to the present accelerating period of expansion. The deceleration parameter supplies the biggest value and the fastest rate at which the universe is expanding. The cosmological term ∧ approaches to zero when t approaches to infinite.

Authors: Sharma Rimmy , Prof. Indra  
Published: June 2020

Abstract
This work deals with “the dynamic analysis of Two-dimensional M/M/1 queuing model with reneging and multiple vacations”. Customers renege according to negative exponential distribution. Dynamic aspect is more appropriate in understanding the behaviour of the system. Two dimensions represent respectively the number of arrivals at, and departure from, the system at a given time. The system starts with “i units at the time “t=0”.Allowing server to take vacationmakes queuing model more feasible in studying the waiting time system appropriately. For example in ticket booking counter, messages to be delivered, patients form queue to have appointments before the clinic open or arrival of doctor. The solution for this model is obtained recursively with the help of Laplace transformation and results are achieved_without involving complex functions.
Certain Results on Prime and Prime Distance Labeling of Graphs
Authors: Parthiban A. , Pir Ajaz Ahmad , Felix A. 
Published: June 2020

Abstract
Let G be a graph on n vertices. A bijective function f : V (G) → {1, 2,…,n} is said to be a prime labeling if for every e = xy, GCD{f (x),f (y)} = 1. A graph which permits a prime labeling is a “prime graph”. On the other hand, a graph G is a prime distance graph if there is an injective function g : V(G) → Z (the set of all integers) so that for any two vertices s & t which are adjacent, the integer |g(s) – g(t)| is a prime number and g is called a prime distance labeling of G. A graph G is a prime distance graph (PDL) iff there exists a “prime distance labeling” (PDL) of G. In this paper, we obtain the prime labeling and prime distance labeling of certain classes of graphs.
Prediction of Two-Node Tandem Queue with Feedback Having State and Time Dependent Service Rates
Authors: Chowdhury Ankita Roy , Indra  
Published: June 2020

AbstractQueuing networks are current area of great research and application interest, in view of their increased applicability in - modelling manufacturing facilities and computer/communication networks, production and assembly lines, hospitals, transport systems, banks and so forth. The present paper develops and analyses a tandem queuing model having two nodes with feedback. Such type of model finds its application in many fields, e.g. telecommunication, inventory, hospitals, traffic control and so on. For example, in hospitals, a patient first visits the doctor and goes through a series of examinations, after which he revisits the doctor for medication. The inter-arrival time is exponentially distributed, whereas the service rate for each node depends on the aggregate of customers in the respective queues and thus follows non-homogeneous Poisson process. After constructing the difference –differential equations, and using PGF technique, we have obtained the joint probability distribution for queue size. Some key measures such as the “average number of customers in queue”, “utilization time of each queue”, “average waiting time in each queue” are computed.

Authors: Kapoor Mamta , Joshi Varun 
Published: June 2020

Abstract
In the present paper Hyperbolic B-Spline based Differential Quadrature Method is proposed to solve the Non-Linear Fisher’s Reaction-Diffusion Equation numerically. By using the proposed method, the governing partial differential equation is converted into a system of ordinary differential equations and then SSP-RK43 scheme is implemented. Accuracy of the proposed method is checked by using discrete root mean square norm (L
2) and maximum error norm(L
∞). A comparison has been made of proposed numerical scheme with the previous numerical schemes already present in the literature. The noteworthy point here is that the proposed numerical scheme is easy to use and indicates some better results.

Authors: Deep Shikha , Sharma Vikas 
Published: June 2020

Abstract
The present problem is a precise approach for the investigation of Love type waves propagation in a new geometric scheme, which consist a dry sandy layer resting over an isotropic elastic half-space. An analytical approach has been used to derive secular equation for the propagation of Love type waves. Dispersion equation for Love type waves is derived in the given geometry by considering that upper dry sandy layer is imperfectly bonded to lower isotropic half-space. The effects of various parameters such as sandiness parameter, imperfect interface and thickness of the layer are presented on the propagation of Love type waves through graphical representations.
Equitable power domination number of total graph of certain graphs
Authors: Banu Priya S , Parthiban A , Abirami P 
Published: June 2020

Abstract
Let G (V, E), or simply G, be a graph. A set S ⊆ V is said to be a power dominating set (PDS) if every vertex u ∈ V − S is observed by certain vertices in S by the following two rules: (a) if a vertex v in G is in PDS, then it dominates itself and all the adjacent vertices of v and (b) if an observed vertex v in G has k > 1 adjacent vertices and if k − 1 of these vertices are already observed, then the remaining one non-observed vertex is also observed by v in G. A power dominating set S ⊆ V in G is said to be an equitable power dominating set (EPDS), if for every vertex v ∈ V − S there exists an adjacent vertex u ∈ S such that |d(u) − d(v)| ≤ 1, where d(u) and d(v) represents the degree of u and degree of v, respectively. The minimum cardinality of an EPDS of G is called the equitable power domination number (EPDN) of G, denoted by γepd
(G). The vertices and edges of G are called elements. Two elements of G are neighbors if they are either incident or adjacent in G. The total graph T(G) has vertex set V(G) ∪ E(G) and two vertices of T(G) are adjacent whenever they are neighbors in G. In this paper, we obtain the EPDN of the total graph of certain graphs.
