Effects of Cloisite 20A Dispersion on the Structure and Properties of LDPE/Modified Clay/Coupling Agent Ternary Nanocomposites
Authors : Haydar U. Zaman,Ruhul A. Khan,


In this study, low-density polyethylene (LDPE)/modified clay (Cloisite 20A) nanocomposites were formed by melt-mixing Cloisite 20A with LDPE and coupling agent, low molecular weight oxidized polyethylene (OxPE). The effects of cloisite 20A, and OxPE on the morphological, mechanical, thermal and flame retardant properties of ternary nanocomposites based on LDPE were evaluated. The structural... Read More

Effectiveness of Wastewater Purification with Watermelon Seed Chaff
Authors : M.M. Chukwu,J.C. Obijiaku,R.E. Obijiaku,C. Ononogbo,J.C. Offurum,


Watermelon seed chaff was used to treat industrial wastewater from a paint industry. The packed bed filtration method was adopted, as the effect of the bed height, together with the adsorbent particle size were monitored. Adsorbent particle sizes of 1.18mm, 0.60mm and 0.125mm were used to pack the glass column at varying heights of 4cm, 6cm, 8cm and 10cm, while 100mls of the wastewater was... Read More

The performance evaluation of a dual flat-plate solar thermal collector suitable for diurnal heating and nocturnal cooling applications is presented. Two collectors, each with estimated area of 0.784 m2 were designed, developed and experimentally investigated. The plates were made with mild steel and coated with matte black and polyethylene terephthalate (PET) powder. The results obtained showed... Read More

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,


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,


: 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

A Novel Approach for Smart Irrigation System using IoT Techniques
Authors : S. Sumathi,S. Krishnan,R. Aravind Kumaran,


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

Design and Analysis of Multiplier Accumulator Circuit for DSP Applications
Authors : Avian Frank,K. B. Ramesh,


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

On Modification of Mismatch-Induced Stresses during Microwave Annealing of Radiation Defects Generated during the Radiation Processing of a Heterostructure
Authors : E.L. Pankratov,


In this paper we formulate recommendations to decrease mismatch-induced stress in a heterostructure during microwave annealing of radiation defects, which were generated during radiation processing. Also we considered an analytical approach to analyze mass and heat transfer during the considered process. The approach gives a possibility to take into account changes in the parameters of processes... Read More

An Analysis of Periocular Region Recognition
Authors : R. Sheela,R. Suchithra,


Periocular biometrics has been established as an independent modality due to concerns on the performance of iris or face systems which is uncontrolled. This paper presents the evaluation and comparison of pericocular recognition techniques such as ReLU non-linearity, DeepIrisNet, FaceNet, Light CNN, Multimodal CNN, Deep CNN, RGB-OCLBCP and to applied on a dataset of images from UBIPr, CASIA-Iris...

Cartesian Products over Interval Valued Intuitionistic Fuzzy Sets of Second Type
Authors : K. Rajesh,R. Srinivasan,


The Intuitionistic Fuzzy Set (IFS) based on fuzzy theory, which is of high efficiency to solve the fuzzy problem, has been introduced by Atanassov. Subsequently, he published the research one step further from the IFS to the Interval Valued Intuitionistic Fuzzy Sets (IVIFS). On the basis of fuzzy set (FS), the IFS are a generalization concept. And the IFS are generalized to the IVIFS. In this... Read More

Authors : V. Hariharan,V. Aroulmoji,M. Mala,V. Karthik,


Pure and doped WO3-x nanoparticles were prepared by facile microwave irradiation method and investigated for strong photocatalytic activity due to the great importance of oxygen vacancies (V0). In the present study, pure and "Fe (~3wt.%)" doped WO3-x nanoparticles and their crystalline nature were evaluated using powder X-ray diffraction (XRD). Bandgap analysis on W17O47 has band gap values due... Read More
