Harmonic and Anharmonic Oscillator Models for Pure Vibrational Infrared Spectroscopy of Diatomic Molecules
Authors : Rohit Singh,

https://doi.org/10.29294/IJASE.8.1.2021.2016-2024

In molecular vibrational infrared spectroscopy, absorption spectra arise from molecular vibration and correspond to transitions between the vibrational energy levels associated with a given electronic state of the molecule. The vibrational transitions, which fall in the near infrared region, are induced through the interaction of the molecular electric dipole with the electric vector of the... Read More

Authors : Dragan Obradovic,Lakshmi Narayan Mishra,Vishnu Narayan Mishra,

https://doi.org/10.29294/IJASE.8.1.2021.2041-2045

The primary goal of the paper is to deliver a simple proof of equivalence between Brouwer’s fixed point theorem and the existence of equilibrium in a simple exchange model with monotonic consumers. To achieve this end, we discuss some equivalent formulations of Brouwer’s theorem and prove additional ones, that are ’approximating’ in character or seem to be better... Read More

Increasing the Density of Field-Effect Heterotransistors in an Amplifier Flipped Voltage Follower Mirrors with Account of Miss-Match Induced Stress
Authors : E.L. Pankratov,

https://doi.org/10.29294/IJASE.8.1.2021.2046-2068

In this paper, we introduce an approach to increase density of field-effect transistors framework current mode instrumentation amplifier flipped voltage follower mirrors. The approach we consider for manufacturing of the inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that dopant and... Read More

Pre-Local Function in Ideal Topological Spaces
Authors : Fadhil Abbas,

https://doi.org/10.29294/IJASE.8.1.2021.2085-2089

The aim of this paper is to introduce the notation of pre-local function A^(p^* )(I, τ) by using pre-open sets in an ideal topological space (X, τ, I). Some properties and characterizations of a pre-local function are explored Pre-compatible spaces are also defined and investigated. Moreover, by using A^(p^* )(I, τ) we introduce an operator ψ: P(X)→τ satisfying ψ(A) =... Read More
