Prediction of Heart Disease Using Machine Learning Algorithms

The successful experiment of data mining in highly visible fields like marketing, e-business, and retail has led to its application in other sectors and industries. Healthcare is being discovered among these areas. There is an opulence of data available within the healthcare systems. However, there is a scarcity of useful analysis tool to find hidden relationships in data. This research intends to provide a detailed description of Naïve Bayes and decision tree classifier that are applied in our research particularly in the prediction of Heart Disease. Some experiment has been conducted to compare the execution of predictive data mining technique on the same dataset, and the consequence reveals that Decision Tree outperforms over Bayesian classification

Enhancement of reactivity and increased usage of low lime class -F-fly ash-possible avenues

The low lime class-F fly ash available in the country shows high degree of variability in the quality, higher content of crystallites , lower glassy phase which accounts for lower of usage in cement and concrete . The time reactivity test used for assessing the pozzolanicity of fly ash did not always correlate with its observed reactivity in Blended cements . An alternative rapid alkali reactivity rest developed at the authors ' laboratory is illustrated in the paper. The paper also discusses the possibility of increasing the reactivity of fly ash and effect of the reactive fly ash on characteristics of PPC and concrete. The paper further discusses other avenues of fly ash utilisation, which could be categorised as low, medium and high value applications. One of such applications developed at the authors ' laboratory that merits special interest, is the Hydrogel process of clinkerisation , which has a potential for utilisation of 20-30% fly ash as a raw material in cement manufacture

Compromise: An Effective Approach for Designing Composite Conical Shell Structures

The layout of fiber composite structures compared to that of structures made from conventional homogeneous isotropic materials is far more difficult, because a fiber composite (laminate) is built up of several unidirectional layers (UD-layers) with fibers set at different angles. A contribution to the structural analysis and preliminary design of a fiber-reinforced conical shell is made in this paper Design of Composite Material Shells In modern lightweight structures, shells of revolution fabricated of fiber composite materials, e.g., fuel tanks, are becoming increasingly important. These shell structures can mostly be built up from different well known shell types, e.g., spherical, cylindrical and conical shells, simplifying the stress and deformation calculations. A more difficult problem is calculating the stress concentrations which appear at the connections of the different shell types. The reason being that the deformations of the different shell types under similar loading are not the same and so bending and shear effects appear. The high stresses at the connection decrease rapidly away from it, so that for the most part of the shell the membrane stresses are important. Thus, to design a shell structure one must use both the membrane theory and bending theory. The bending theory for composite material structures is much more complicated than for structures made of homogeneous and isotropic materials. Therefore, we have to find a way to design shell structures using only the membrane theory. This is possible if the stiffnesses of the different shell types can be changed in a way that the strains (or the deformations) at the connections are the same. By using composite materials, instead of isotropic materials, the stiffness can be changed by using different layer orientations in a laminate and increasing or decreasing the layer thickness. To find the appropriate layer orientation and thickness optimization methods can be applied. Before one can build up a whole shell structure out of spherical, cylindrical and/or conical shells the deformation behavior of the different shell types has to be studied in detail. In references [1] and [2] several parametric studies and the "optimum" design of spherical and cylindrical shells under pressure and temperature loads are given. Battermann and Pavicic [3] published a paper about weight minimization of laminated shells of revolution where the laminate is built up as a symmetrical angle-ply laminate. They found the optimal results by doing a lot of calculations with different laminate parameters, e.g., fiber angles and laminate thicknesses. Most of the publications in the field of optimum design of composite shells have dealt with weight minimization including stability and/or vibration constraints, see Our paper deals with the structural analysis and preliminary design of a thin conical shell subjected to a pressure load and a temperature distribution along the meridian direction, as shown in A comprehensive approach called the Decision Support Problem (DSP) Techniqu

The Parametric Ordinal-Recursive Complexity of Post Embedding Problems

Post Embedding Problems are a family of decision problems based on the interaction of a rational relation with the subword embedding ordering, and are used in the literature to prove non multiply-recursive complexity lower bounds. We refine the construction of Chambart and Schnoebelen (LICS 2008) and prove parametric lower bounds depending on the size of the alphabet.Comment: 16 + vii page

Prox-imal Femoral Nail in Reverse Trochanteric Femoral Fractures: An Analysis of 53 Cases at One Year Follow-Up

Abstract Treatment of reverse oblique trochanteric femoral fractures poses a lot of challenges. There have been proponents of intramedullary devices as well as extramedullary devices. We present the results of proximal femoral nailing surgery performed for reverse obliquity intertrochanteric fractures using two proximal lag screws and a nail of 250 mm. There is prospective study of fifty three patients with AO/OTA 31 A-A3 fractures being treated by proximal femoral nailing in our institute after seeking approval from the Hospital ethics board. The quality of the reduction, the operative time, complications and the functional status of the patients were the parameters on which the results were evaluated. The mean Harris hip score was 76.66 (range 70 -93) and the mean Barthel activity score was 16.21 (range 12 -20). The average surgical time was 50 minutes and the mean consolidation time was 11.5 weeks. Intramedullary nailing with proximal femoral nails seems to be a good option in the treatment of reverse obliquity intertrochanteric fractures as against the various existing options available for the management

Renormalization: a quasi-shuffle approach

In recent years, the usual BPHZ algorithm for renormalization in perturbative quantum field theory has been interpreted, after dimensional regularization, as a Birkhoff decomposition of characters on the Hopf algebra of Feynman graphs, with values in a Rota-Baxter algebra of amplitudes. We associate in this paper to any such algebra a universal semi-group (different in nature from the Connes-Marcolli "cosmical Galois group"). Its action on the physical amplitudes associated to Feynman graphs produces the expected operations: Bogoliubov's preparation map, extraction of divergences, renormalization. In this process a key role is played by commutative and noncommutative quasi-shuffle bialgebras whose universal properties are instrumental in encoding the renormalization process

The 'K' selected oligophilic bacteria: a key to uncultured diversity?

Molecular techniques have made it increasingly clear that a large proportion of bacterial diversity in natural habitats is uncultured and therefore unexplored. We suggest and give evidence in support of a hypothesis that a large proportion, if not all, of the uncultured diversity from a variety of aquatic and terrestrial habitats are oligophilic (oligotrophic) bacteria. Oligophilic bacteria grow only on dilute nutrient media and form small or microscopic colonies. A technique to cultivate and isolate the moderately oligophilic bacteria was developed and 90 cultures isolated, The twelve bacterial cultures characterized showed high growth yield coefficients and carbon conversion efficiencies at low substrate concentrations and progressively decreased with increasing substrate concentrations. Most of the growth yields were substantially higher than those reported in the literature and lie near the theoretical maximum. Slow growth rates and high yields indicate that they are 'K' selected species. 16S rDNA partial sequence analysis of the isolates indicates that it is a novel as well as diverse group
