Nanoparticle Delivery via Stocky SWCNTs, A Nonlinear-Nonlocal Continuum-based Scrutiny

Excellent mechanical properties plus to the good biocompatibility of single-walled carbon nanotubes (SWCNTs) are offering them as efficient nanodevices for delivering of nanoparticles. Due to the friction between the outer surface of the nanoparticle and the inner surface of the SWCNTs, mass weight of the nanoparticle, and the interactional van der Waals (vdW) forces between the constitutive atoms of the nanoparticle and those of the SWCNT, both longitudinal and transverse waves propagate wit...

Nonlinear Vibrations of a Single-walled Carbon Nanotube for Delivering of Nanoparticles

The capability of carbon nanotubes (CNTs) in efficient transporting of drug molecules into the biological cells has been the focus of attention of various scientific disciplines during the past decade. From applied mechanics points of view, translocation of a nanoparticle inside the pore of a CNT would result in vibrations. The true understanding of the interactive forces between the moving nanoparticle and the inner surface of the CNT is a vital step in factual realization of such vibrations...

On the Interaction of a Single-walled Carbon Nanotube with a Moving Nanoparticle Using Nonlocal Rayleigh, Timoshenko, and Higher-order Beam Theories

Interaction of a moving nanoparticle with a single-walled carbon nanotube (SWCNT) is of concern. The SWCNT is simulated by an equivalent continuum structure (ECS) under simply supported boundary conditions. The moving nanoparticle is modeled by a moving point load by considering its full inertial effects and Coulomb friction with the inner surface of the ECS. The ECS under the moving nanoparticle is modeled based on the Rayleigh, Timoshenko, and higher-order beam theories in the context of th...

Nonlocal Continuum-based Modeling of a Nanoplate Subjected to a Moving Nanoparticle. Part I, Theoretical Formulations

The potential applications of nano plates in energy storage, chemical and biological sensors, solar cells, field emission, and transporting of nano cars have been attracted the attentions of the nanotechnology community to them during recent years. Herein, the later application of nano plates from non local elastodynamic point of view is of interest. To this end, dynamic response of a nano plate subjected to a moving nano particle is examined with in the context of non local continuum theory ...

Revisiting Free Transverse Vibration of Embedded Single-layer Graphene Sheets Acted Upon by an in-plane Magnetic Field

AbstractMurmu et al. [23] recently presented a nonlocal model for the transverse vibration of simply supported graphene sheets in the presence of a unidirectional in-plane magnetic field. Further studies showed that the majority of Lorentz's force components were improperly provided and led to invalid governing equations. To remove such deficiencies, the most general form of Lorentz's force components is carefully extracted in the present work. The nonlocal equations of motion of the problem ...

Effect of Date Palm Seed Ash as a Supplementary Cementitious Material in Concrete

AbstractThis study investigates the effect of Date Palm Seed Ash (DPSA) as a pozzolan on the workability, compressive strength and water absorption capacity of concrete. Temperature regulated kiln was used to burn the Date Palm Seed (DPS) into DPSA in two stages: it was first burned for eight hours at an optimum temperature of 590oC and then cooled for two days. It was again burned for three hours at an optimum temperature of 630oC for eight hours and was air cooled again for three days. The ...

Early Plant Disease Detection and Recommendation Using ML CNN

Identification of the plant diseases is the key to preventing the losses in the yield and quantity of the agricultural product. Almost 70% people depend on it & shares major part of the GDP. Diseases in crops mostly on the leaves effects on the reduction of both quality and quantity of agricultural products. Perception of human eye is not so much stronger so as to observe minute variation in the infected part of leaf. In this paper, we are providing software solution to automatically de...

Design and Performance Analysis for Welding Fumes Extraction System 1

Abstract During Welding operation, the fumes and metallic gases are emitted from the work piece, which cause the pollution and hazard to workers, when gases were inhaled or ingested. This usually cause respiratory effects such as lung disease, bronchitis and possible of lung cancer. This paper deals with the designing of fume extraction system and evaluate the performance such as efficiency of the system, filtration capacity, and environmental friendly, during the welding proces...

Design of Advanced Peripheral Bus for Universal Asynchronous Receiver-Transmitter

The huge progress of VLSI technology enables the integration of millions of transistor on a single chip called System on chip (SoC).The SoC uses AMBA (Advanced Microcontroller Bus Architecture) as on chip bus protocol. AMBA’s specifications define five buses/interfaces: Advanced extensible Interface (AXI), Advanced High-performance Bus (AHB), Advanced System Bus (ASB), Advanced Trace Bus (ATB), and Advanced Peripheral Bus (APB). AXI, AHB, ASB, ATB which are high performance buses use...

Improving Software Defect Prediction Using Cluster Undersampling

ABSTRACT Adequately learning and classifying datasets that are highly unbalanced has become one of the most challenging tasks in Data Mining and Machine Learning disciplines. Most datasets are adversely affected by the class imbalance problem due to the limited occurrence of positive examples. This phenomenon adversely affects the ability of classification algorithms to adequately learn from these data to correctly classify positive examples in new datasets. Data sampling techniques...
