Comparison of Various Classification Techniques Using Different Data Mining Tools for Diabetes Diagnosis  [PDF]
Rashedur M. Rahman, Farhana Afroz
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.63013
Abstract:

In the absence of medical diagnosis evidences, it is difficult for the experts to opine about the grade of disease with affirmation. Generally many tests are done that involve clustering or classification of large scale data. However many tests could complicate the main diagnosis process and lead to the difficulty in obtaining the end results, particularly in the case where many tests are performed. This kind of difficulty could be resolved with the aid of machine learning techniques. In this research, we present a comparative study of different classification techniques using three data mining tools named WEKA, TANAGRA and MATLAB. The aim of this paper is to analyze the performance of different classification techniques for a set of large data. A fundamental review on the selected techniques is presented for introduction purpose. The diabetes data with a total instance of 768 and 9 attributes (8 for input and 1 for output) will be used to test and justify the differences between the classification methods. Subsequently, the classification technique that has the potential to significantly improve the common or conventional methods will be suggested for use in large scale data, bioinformatics or other general applications.

International Journal of Environment , 2014, DOI: 10.3126/ije.v3i2.10640
Abstract: Nilgiri hills being a part of biodiversity hot spot, is a home of colossal life forms including bryophytes. Bryophytes have a great diversity in Nilgiri hills which includes both terricolous and corticolous forms. This study deals with morphotaxonomy of three extremely infrequent terricolous taxa of order Jungermanniales, viz ., Gottschelia schizopleura (Spruce) Grolle, Lethocolea javanica (Schiffn.) Grolle and Jackiella javanica var. cordifolia Schiffn, occurring in Nilgiri hills. These taxa were located to a few restricted pockets and facing high risk of habitat loss which need urgent/immediate conservation management.

Advances in Bioscience and Biotechnology (ABB) , 2012, DOI: 10.4236/abb.2012.35075
Abstract: Agro-industrial residues are primarily composed of complex polysaccharides that strengthen the microbial growth for the production of industrially important enzymes like cellulases. In the present study we aimed to characterize the Exo 1, 4-β glucanase that was indigenously produced from Trichoderma viride MBL. T. viride MBL was cultured in the Solid-State medium of orange peel (50% w/w moisture) under optimized fermentation conditions and maximum activity of 412 ± 12 U/mL was recorded after 4th day of incubation at pH 5.5 and 30℃. Exo 1, 4-β glucanase was 4.17-fold purified with specific activity of 642 U/mg in comparison to the crude extract. To confirm its purity and molecular weight, sodium dodecyl sulphate poly acrylamide gel electrophoresis (SDS- PAGE) was performed. The enzyme was shown to have a molecular weight of 60 kDa with an optimum pH and temperature of 5 and 50℃, respectively. Lineweaver-Burk reciprocal plot revealed that the kinetic constants Km and Vmax of purified Exo 1, 4-β glucanase were 76 μM and 240 U/mL.
An analytical study of critical heat flux in natural convective boiling in a vertical tube
HMM Afroz, MA Islam
International Journal of Engineering, Science and Technology , 2010,
Abstract: An analytical study is performed for the prediction of Critical Heat Flux (CHF) during natural convective boiling in a vertical uniformly heated tube, submerged in a saturated liquid bath, by a model where vapor forms a paraboloid under co-current flow situation. Mass, momentum and energy balances for the two-phase flow in the vertical tube are used to construct the model together with the criterion that the CHF is considered to be taking place at the exit of the heated tube when mass flux is maximum. About 300 CHF data are predicted for saturated Water, R113 and R12 at different pressures of P = 0.1 to 3.0 MPa for different tube geometries (diameter, D = 1.12 to 18.4 mm, and heating length, Lhe = 23 to 960 mm). The characteristics of CHF predicted by this model are explained and compared with similar existing experimental works. The effects of working fluids, working pressure, and tube geometry are mainly explained and compared to verify the basic performance of the model.
Binary mixtures of carbon dioxide and dimethyl ether as alternative refrigerants and their vapor-liquid equilibrium data predicti
HMM Afroz, A Miyara
International Journal of Engineering, Science and Technology , 2011,
Abstract: Vapor-liquid equilibrium (VLE) data were predicted for the binary mixture of carbon dioxide (CO2) and dimethyl ether (DME) at ten temperatures ranging from 273.15 to 386.56 K and pressure upto 7.9 MPa to observe this mixture’s potential of COP enhancement and capacity modulation as a working fluid in a refrigeration system. Since the mixtures are zeotropic in nature and the components of the mixtures have good thermophysical properties, zero ozone depleting potential (ODP) and low global warming potential (GWP), they are considered as promising alternative refrigerants. The Benedict-Web-Rubin (BWR) and the modified Benedict-Web-Rubin (MBWR) equations of state (EoS) have been used for the prediction of VLE data. For the BWR and MBWR equations of state, respective constant binary interaction parameters have been determined by using the available experimental VLE data of CO2/DME mixtures. The predicted VLE data have been compared with the experimental data and the data obtained from REFPROP version 8.0. Among the comparison results, BWR EoS shows good agreement with the experimental data.
Collarless metal ceramic restorations to obscure the umbrella effect
Afroz Shaista,Chand Pooran
Indian Journal of Dental Research , 2010,
Abstract: Esthetics with porcelain fused to metal restoration in the anterior region can be adversely affected due to the inadequate teeth preparations and design of the prosthesis. We presented here a case report where esthetics was compromised due to darkening of the interdental papilla and marginal gingival and overcontoured restorations in relation to porcelain fused to metal restorations. Good esthetic results were obtained by using basic principles of tooth preparation and using collarless metal ceramic restorations.
