Abstract

This study is concerned with the effect of radiation on flow, heat and mass transfer of Nanofluid flow past over an oscillating vertical plate. Effect of Brownian motion on thermal conductivity and viscosity of nanofluid is considered. Thus effects of nano particle size, volume fraction, temperature, types of nano particle and base fluid combinations are taken into consideration. Specifically we have considered CuO-Water nanofluid. Effect of thermal interfacial thermal resistance is also considered. The governing system of partial differential equations are converted into non-dimensional system and then solved analytically. Flow characteristics are analyzed graphically and the physical aspects are discussed in detail. Skin friction, Nusselt number and Sherwood number are also derived and represented through tables.

Keywords: MHD, Radiation, Nanofluid, Analytic solution, Isothermal, Ramped, Brownian motion.

Abstract

Diabetes observed as DM (diabetes mellitus) describes a collection of metabolic diseases in which the individual has high blood sugar. Probable complications that can be caused by poorly controlled diabetes: Eye problems, Foot problems, Skin problems, Heart issues, cardiovascular disease, etc. Diabetic retinopathy (DR), a widespread complication of diabetes, affects the blood vessels within the retina. Diabetic Retinopathy is human eye disease which causes damage to the retina of the eye and it may eventually lead to complete blindness. Detection of diabetic retinopathy in the early stage is essential to avoid complete blindness. Many physical tests like visual acuity test, pupil dilation, and Optical Coherence Tomography (OCT) can be used to detect diabetic retinopathy but are time- consuming and affects patients as well..............

Abstract

Glaucoma is an ocular disease having common traits like, high eye pressure, injury to the Optic nerve and gradual vision loss. It affects peripheral vision and eventually results in cecity if left untreated. The existing techniques of pre-diagnosis of glaucoma incorporate measurement of Intra-ocular pressure, corneal thickness, and angle using tonometry, Pachymetry, and gonioscopy that are executed physically by the clinicians. These tests are followed by optic nerve head appearance examination for the complete diagnosis of Glaucoma. The diagnoses require regular examine, which is too expensive and time consuming. The accuracy and reliability of diagnosis is partial by the domain knowledge of different ophthalmologists...........

Abstract

The rapidly growing field of big data has played a major role in the growth of health care. Big Data analytics facilitates the process of early detection and cure of diseases. The word Big Data brings along with it the various V's associated with it. In this paper, we speak about the veracity issue of Big Data and show how it can lead to better prediction if handled well. We have used age and sex as factors to group patient's based on a standard prescribed by cancer foundation. Modified Moving Average(MMA) is used to predict the missing values. We have used data of a disease called ALS (Amyotrophic Lateral Sclerosis) to prove the correlation between patients. It was found that the results of prediction are better when veracity is handled than when not.

Keywords: Accuracy, Auto Regression Tree, Big Data, Modified Moving Average, Non Linear Regression, Specificity, Veracity.

Abstract

TCP- transmission manipulate protocol is a connection oriented and reliable process-to-process communication on the transport layer of tcp/ip model. TCP guarantees with the end-to-end flow control, error control and congestion control ears in the past, tcp was brought to work with the stressed out networks where the cause of losses is specially the network congestion. TCP was introduced to work with the wired networks where the cause of losses is mainly the network congestion. In recent years, wireless networking is becoming more and more popular. In current years, wireless networking is turning into increasingly more famous. A full-size quantity of performance degradation is found while conventional tcp versions are used with the wi-fi networks. Wireless networks are greater prone to the losses due to the inherent impairments of wi-fi verbal exchange. This paper surveys various TCP variants with wireless multi-hop networks. Simulation is carried out with NS 2.35.

Keywords: TCP, wireless, NS 2.35.

International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 11 (November – 2017)

Abstract

The Indian planners, right from the beginning, realized the need to attain self-sufficiency in food grains as one of the important goals of planning. The government realized that food surplus countries used food surplus as a weapon to force several countries to submit to their dictates. Prime Minister JAWAHARLAL NEHRU realized that it was with the great difficult that India was able to avoid the political strings attached with the food aid, but it did hurt national pride. In one of his broadcasts to the nation, NEHRU stated very candidly "we have sought help from abroad… and we shall continue to do so under pressure of necessity, but the conviction is growing upon me more forcefully than ever how dangerous it is for us to depend for this prime necessary of life on foreign countries............

Abstract

Square difference prime labeling of a graph is the labeling of the vertices with {0,1,2---------,p-1} and the edges with absolute difference of the squares of the labels of the incident vertices .The greatest common incidence number of a vertex (gcin) of degree greater than one is defined as the greatest common divisor of the labels of the incident edges. If the gcin of each vertex of degree greater than one is one, then the graph admits square difference prime labeling. Here we investigate; some cycle related graphs for square difference prime labeling.

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 11 (November – 2017)

Abstract

The drag characteristics of different combinations of cubical surface protrusions were studied using computational analysis tools in order to better understand the drag physics. Initially, the results from a flat plate simulation was validated with experimental results to ensure that the computational solutions obtained were reliable. Following the validation study, geometric features of the simulation domain was modified to establish its effect in drag values. This provided insight into the effect of the wall of water tunnel on the drag characteristics. Once a baseline setup was arrived at, surface protrusions were added onto the top surface of the flat plate and the drag characteristics studied. It was found that the addition of a single cubical protrusion of frontal area of 1cm2 at low Reynolds number increased the drag by approximately 10%. Surface protrusions were later added in the row-wise and column-wise configurations to establish its effect on drag values.

Keywords: CFD analysis, Low Reynolds number, Wall mounted Cubes, Drag Coefficient, Laminar flow, Inline and Staggered.

International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 11 (November – 2017)

Abstract

Smart materials are the materials where in one or more properties can be significantly changed in a controlled fashion by external stimuli, such as temperature, stress, moisture etc. Among various types of smart materials, piezoelectric materials are mostly use because, theoretical analysis of this material has been so well developed. In this work an attempt has been made to analyze the piezolaminated composite plates subjected to electromechanical loading using higher order shear deformation theory (HSDT) for more accurate results. For analysis two displacement models are to be considered i.e., model-1 accounts for strain in thickness direction is zero whereas in model-2 in-plane displacements are expanded as cubic functions of the thickness coordinate. The solutions are obtained using Navier's method for anti-symmetric cross ply and angle ply composite laminated plates attached with piezoelectric layer with a specific type of simply supported boundary conditions.

Keywords: Angle ply, cross ply, HSDT, Navier's method, piezolaminated composite plates and smart materials.
