A hybrid of multiple linear regression clustering model with support vector machine for colorectal cancer tumor size prediction
This study proposed the new hybrid model of Multiple Linear Regression Clustering (MLRC) combined with Support Vector Machine (SVM) to predict tumor size of colorectal cancer (CRC). Three models: Multiple Linear Regression (MLR), MLRC and hybrid MLRC with SVM model were compared to get the best model in predicting tumor size of colorectal cancer using two measurement statistical errors. The proposed model of hybrid MLRC with SVM have found two significant clusters whereby, each clusters contained 15 and three significant variables for cluster 1 and 2, respectively. The experiments found that the proposed model tend to be the best model with least value of Mean Square Error (MSE) and Root Mean Square Error (RMSE). This finding has shed light to health practitioner in determining the factors that contribute to colorectal cancer
A study of nanoparticles as a drug carrier on the wall of Stenosed Arteries
The influences of nanoparticles as drug carriers on the walls of stenosed arteries are presented. In this study, three nanoparticles namely Fe3O4 , TiO2 and Cu were used. It is observed that the addition of Fe3O4 nanoparticles tends to reduce the resistance impedance of blood temperature in bell shaped stenosed arteries. The blood temperature increases slightly in the streamwise direction before the throat region. Thereafter, the blood temperature increases at a higher rate and reaches its maximum value at the stenosis throat. It is found that the temperature distribution is heavily dependent on parameters such as periodic body acceleration and Prandtl number
Unsteady blood flow with nanoparticles through stenosed arteries in the presence of periodic body acceleration
The effects of nanoparticles such as Fe304,Ti02, and Cu on blood flow inside a stenosed artery
are studied. In this study, blood was modelled as non-Newtonian Bingham plastic fluid subjected to periodic
body acceleration and slip velocity. The flow governing equations were solved analytically by using the
perturbation method. By using the numerical approaches, the physiological parameters were analyzed, and
the blood flow velocity distributions were generated graphically and discussed. From the flow results, the
flow speed increases as slip velocity increases and decreases as the values of yield stress increases
Review on queueing problem in healthcare

A summary of queueing, simulation and scheduling theory used in waiting time, appointment system and patient flow are summarised in this article. Different departments in the healthcare system are also considered in this article such as emergency department, outpatient department and the pharmacy. The aim is to provide the reader a general background into queueing, simulation and scheduling in the healthcare
The effects of magnetic casson blood flow in an inclined multi-stenosed artery by using caputo-fabrizio fractional derivatives
Hemodynamic is the knowledge of blood circulation, which is useful in the diagnosis of coronary
illness. The reason behind the malfunction of cardiovascular system is the presence of fats,
cholesterol and lipoproteins at the sites of atherosclerotic lesion in the artery [1]. In recent years,
due to its great importance in the human cardiovascular system, the study of blood flow through
constricted arteries has received a great deal of attention [2–4]. Prasad and Radhakrishnamacharya
[5] considered the steady blood flow through an inclined non-uniform tube with multiple stenoses.
Agarwal and Varshney [6] studied the flow of Herschel-Bulkley fluid through an inclined tube of nonuniform
cross-section with multiple stenoses. Biswas and Paul [7] observed the steady blood flow
through an inclined tapered vessel, where the blood was modelled as Newtonian fluid and the slip
vessel wall condition was applied. Also, their analysis includes one-dimensional Poiseuille blood flow
through tapered vessels with inclined geometries. Ismail and Jamali [8] explored the dynamic
response of heat transfer in the steady laminar blood flow through the stenotic bifurcated artery
