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...
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...
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...
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 ...
Abstract Murmu 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...
Abstract This 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...
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 detect a...
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 used to in...
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 presente...
Indubitably the most challenging coronavirus (Covid-19) outbreak, caused by SARS-CoV-2. With the number of Covid-19 cases now approaching millions globally so, for controlling the current infection rate, we have come up with this innovation of virus repellent electric liquid vaporizer means by vaporization of the solution which is the in-liquid form by means of electricity, which will enable the infectious virus and bacteria to be less effective also it will sometime kill the virus in a small...
ABSTRACT Identification of exhaust fan bearing defects has its root foundations in the analysis of frequency modulation and sensing using mostly online techniques. Centrifugal fans are the most commonly used fans in the industry today. They are preferred to axles because they are cheaper and constructed with simplicity. They are used in wind systems in vehicles and buildings and also in delivering gas or minerals. They are suitable for industrial and air pollution processes and systems. Fa...
