(1, 3) solid burst-correcting optimal linear codes over GF(5)
TARUN LATA 장전수학회 2018 Proceedings of the Jangjeon mathematical society Vol.21 No.4
In 2012, Das [5] had obtained a lower bound on the neces- sary number of parity-check digits in an (n = n₁ + n₁, k) linear codes over GF(2) which are optimal in a specic sense viz. which are capa- ble to correct single errors in the rst sub-block of length n1 and solid bursts of length 3 or less in the second sub-block of length n2 as well as gave sucient condition for the existence of such codes. Later, Lata and Tyagi [9] had studied these codes over GF(3). In this paper, the author examines the possibility of the existence of such codes over GF(5).

Rabri is a concentrated whole milk product from India that has been heat desiccated and sweetened. Herbs are reported to possess therapeutic properties. The addition of these herbs in the food enhances the functionality of the food. Herbal apple rabri was prepared by adding two herbs (brahmi and shatavari). The herbal apple rabri was optimized based on its organoleptic attributes. The sensory evaluation revealed that adding brahmi up to 2.5% and shatavari up to 1.5% is acceptable. The optimized rabri was further analyzed for its texture profile. The shelf life was evaluated based on the physicochemical, antioxidant, phenolics, and microbial content like total plate count and yeast and molds count. The DPPH inhibition activity shows that the optimized rabri has antioxidant potential (58.41 ± 0.03%) compared to control rabri (34.30 ± 0.04%) due to adding herbs. The microbial spoilage in the optimized sample was less as compared to the control sample.

This investigation is focused on the study of effect of hall current in transversely isotropic magneto thermoelastic homogeneous medium with fractional order heat transfer and rotation. As an application the bounding surface is subjected to normal force. The research becomes more interesting due to interaction of Hall current with the effect of rotation as it has found various applications. Laplace and Fourier transform is used for solving field equations. The analytical expressions of temperature, displacement components, stress components and current density components are computed in the transformed domain. The effects of hall current and fractional order parameter at different values are represented graphically.

The aim of the present investigation is to examine the propagation of plane waves in transversely isotropic homogeneous magneto thermoelastic rotating medium with fractional order heat transfer. It is found that, for two dimensional assumed model, there exist three types of coupled longitudinal waves (quasi-longitudinal, quasi-transverse and quasi-thermal waves). The wave characteristics such as phase velocity, attenuation coefficients, specific loss, penetration depths, energy ratios and amplitude ratios of various reflected and transmitted waves are computed and depicted graphically. The conservation of energy at the free surface is verified. The effects of rotation and fractional order parameter by varying different values are represented graphically.

The present study is concerned with the thermoelastic interactions in a two dimensional axisymmetric problem in transversely isotropic thermoelastic solid using new modified couple stress theory without energy dissipation and with two temperatures. The Laplace and Hankel transforms have been employed to find the general solution to the field equations. Concentrated normal force, normal force over the circular region, concentrated thermal source and thermal source over the circular region have been taken to illustrate the application of the approach. The components of displacements, stress, couple stress and conductive temperature distribution are obtained in the transformed domain. The resulting quantities are obtained in the physical domain by using numerical inversion technique. The effect of two temperature varying by taking different values for the two temperature on the components of normal stress, tangential stress, conductive temperature and couple stress are depicted graphically.

The present research deals with the time-harmonic deformation in transversely isotropic magneto thermoelastic solid with two temperature (2T), rotation due to inclined load and laser pulse. Generalized theory of thermoelasticity has been formulated for this mathematical model. The entire thermo-elastic medium is rotating with uniform angular velocity and subjected to thermally insulated and isothermal boundaries. The inclined load is supposed to be a linear combination of a normal load and a tangential load. The Fourier transform techniques have been used to find the solution to the problem. The displacement components, stress components, and conductive temperature distribution with the horizontal distance are computed in the transformed domain and further calculated in the physical domain using numerical inversion techniques. The effect of angle of inclination of normal and tangential load for Green Lindsay Model and time-harmonic source for Lord Shulman model is depicted graphically on the resulting quantities.

This research is devoted to the study of plane wave propagation in homogeneous transversely isotropic (HTI) magneto-thermoelastic rotating medium with combined effect of Hall current and two temperature due to multi-dual-phase lag heat transfer. It is analysed that, for 2-D assumed model, three types of coupled longitudinal waves (quasi-longitudinal, quasi-transverse and quasi-thermal) are present. The wave characteristics like phase velocity, specific loss, attenuation coefficients, energy ratios, penetration depths and amplitude ratios of transmitted and reflected waves are computed numerically and illustrated graphically and compared for different theories of thermoelasticity. Some particular cases are also derived from this research.
Effect of rotation and inclined load in a nonlocal magneto-thermoelastic solid with two temperature
Lata, Parveen,Singh, Sukhveer Techno-Press 2022 Advances in materials research Vol.11 No.1
This work deals with the two-dimensional deformation in a homogeneous isotropic nonlocal magneto-thermoelastic solid with two temperatures under the effects of inclined load at different inclinations. The mathematical model has been formulated by subjecting the bounding surface to a concentrated load. The Laplace and Fourier transform techniques have been used for obtaining the solution to the problem in transformed domain. The expressions for nonlocal thermal stresses, displacements and temperature are obtained in the physical domain using a numerical inversion technique. The effects of nonlocal parameter, rotation and inclined load in the physical domain are depicted and illustrated graphically. The results obtained in this paper can be useful for the people who are working in the field of nonlocal thermoelasticity, nonlocal material science, physicists and new material designers. It is found that there is a significant difference due to presence and absence of nonlocal parameter.
