Effects of Filler Content and Compatibilizers on the Properties of Low-Density Polyethylene (LDPE)/Thermoplastic Potato Starch (TPS) Blend Composite
Authors : Haydar U. Zaman,Ruhul A. Khan,

https://doi.org/10.29294/IJASE.8.4.2022.2371-2383

In this study, potato starch (PS) was physically mixed with low-density polyethylene (LDPE) through twin screw extruder to form LDPE/PS composites. Glycerol was added to the mixture as a plasticizer to increase the compatibility of PS and LDPE, which subsequently reduced the brittleness of the composite. The effect of thermoplastic potato starch (TPS) content and two different compatibilizers on... Read More

A comparative Study of Atomic Entanglement in Single Mode Jaynes Cummings Model with Multiphoton Interaction
Authors : Dr. Amrita,Rohit Singh,

https://doi.org/10.29294/IJASE.8.4.2022.2384-2390

: In the present paper, standard Jaynes Cummings model involving multiphoton interaction between the field and the atom has been considered. We study the variation of entanglement properties of a pair of two–level Rydberg atoms passing one after another into a lossless cavity with single mode multiphoton interaction. The initial joint state of two successive atoms that enter the cavity is... Read More

On Increasing the Density of a Single-Stage Differential-Drive CMOS Heterorectifier under the Influence of Missmatch-Induced Stress and Porosity of Materials
Authors : E.L. Pankratov,

We analyzed the possibility to increase density of field-effect transistors framework a single-stage differential-drive CMOS rectifier. Based on this analysis we formulate recommendations to obtain the above increasing with increasing of homogeneity of dopant distribution in doped area. We also consider a possibility to decrease value of mismatch-induced stress in the considered heterostructure.... Read More

The paper presents a significant index in the evaluation of rural areas by monitoring the conditions of soil and water in agriculture. There are several factors that affect agriculture, which may be lack of water facilities, proper pesticide utilization at the proper time, and sometimes due to the low soil moisture content available in the soil. The soil and water conditions and how they can... Read More

Authors : Avian Frank,K. B. Ramesh,

https://doi.org/10.29294/IJASE.8.4.2022.2425-2430

Multipliers and Accumulators are an imperative component of DSP application systems. It plays a vital role in high speed digital signal processing (DSP), image processing multiplier and processing fast Fourier transform (FFT). These computations require large number of multiplication and addition operation which requires dedicated MAC and Arithmetic and Logic Unit (ALU) architectures.... Read More
