We propose a new methodology for the prediction of cardiac disease with the help of wavelet transform and Hidden markov model. In most of the occasions the variation in the human heart rate is unidentifiable due to the small voltage variation could not recordable with graph generated by ECG.  The small difference in the ECG may also notify the presence of cardiac problem which could not be identified with human intervenes.  The Electro cardiogram signals are passed through wavelet filter for the identification of small variation and then classified with probabilistic models. The wavelet transform boost the signals so that the small variation also become accountable and then we used hidden markov model for the identification of pattern which is relevant to identify cardiac diseases.

Microwave energy has gained worldwide acceptance as a novel method for heating, sintering and phase transformation of minerals and materials, as it offers specific advantages in terms of speed, energy / power efficiency, process simplicity, improved properties and produces the finer microstructures. This paper deals with a review on the advances in the microwave treatment of minerals. It shows the beginning of using the microwave energy as early stages of development for future processes for industries. Many different applications are considered, including fundamental heating rate studies on pure minerals, and its applications on ores, microwave assisted grinding, selective mineral liberation, possible exploitation in the area of extractive metallurgy, phase transformation, enhancement of magnetic and electrical separation, saving of energy, decomposition/ recycling of wastes. Conclusions are drawn on the need for further scope on fundamental and pilot investigations. This paper also shows that microwave energy is a clean and eco-friendly process for obtaining the value added products as compared to conventional method.

Time-tabling can be considered to be a certain type of scheduling problem. There is a wide variety of time-tabling problems one of which is known as university time-tabling. In this kind of problem, there are a lot of university courses requiring scheduling while avoiding overlap in any particular term. There are several approaches to solving such problems. This article focuses on a graph-based solution. By modeling a graph-based solution, we are able to gain a coloring problem which can then be used to obtain a complete solution to the problem through SFSG: SDO proper coloring algorithm, followed by BFD method.

This study presents laboratory experimental study on the effect of inclusion of polypropylene fiber in clay soil sample. The initial work of the experimental program presents the study of the effect of polypropylene fiber on maximum dry density and optimum moisture content with different fiber inclusions. The light compaction tests have been conducted on a clay soil sample with 0%, 0.25%, 0.50%, 0.75%, 1.0% and 1.25% in additions of polypropylene fiber and the samples have been prepared with the same dry density. At the different stages of admixtures of polypropylene fiber with clay soil sample were tested and the maximum dry density and optimum content of fiber was found. The further study of experimental work focuses on the unconfined compression test, California bearing ratio test and swelling behavior of the soil sample. The experimental test results indicated that addition of polypropylene fiber inclusions in stabilized clay results in higher bearing strength values and California bearing ratio values.
