Vast growth of biomedical databases has increased most of the researchers focus on the field of Text Mining. The documents appear in unstructured format. To process and discover knowledge from these data, the unstructured databases must be converted to structured format. For this task Text mining plays a vital role. Text preprocessing is an essential step in text mining. The common preprocessing tasks...
In power generation, renewable energy plays an important role. With the increase in the energy demand, there is a need for a renewable energy source that will fulfil the required demand and also which is environmental friendly. When sunlight falls on a Photovoltaic (PV) module, direct current (dc) is produced and little maintenance is required for PV modules. Maximum Power Point Tracker (MPPT) helps...
Energy requirements of whole world have been dominated by petroleum products for many years in various application fields. In order to find the potential replacement for conventional mineral oil, natural based ester oil is proposed as alternative liquid insulation with the consideration of eco-friendly nature among ester oil, the oil with oleic acid content has oxidation resistance and low viscous...
Farmers are facing a lot of difficulties because of the increasing monkey menace in the Indian Agricultural land. The massive fruit and vegetable crops worth crores of rupees were fully damaged and destroyed by the monkeys. In an opinion survey that was conducted based on the monkey menace, it was discovered that monkeys are becoming a threat for public health, crop and property. Most people in the...
This paper proposes a new hybrid classification technique for recognizing printed digits. The feature extraction was performed using object region boundary analysis, Fourier Descriptors (FD) and Chain code based algorithm. A new curve tracing Chain code based algorithm (CTCC) was proposed to extract the curve features from the digit images. The recognition was performed using dynamic programming and...
Breast cancer is one of the most common cancers worldwide. In developed countries, among one in eight women develop breast cancer at some stage of their life. Early diagnosis of breast cancer plays a very important role in treatment of the disease. With the goal of identifying genes that are more correlated with the prognosis of breast cancer, we use data mining techniques to study the gene expression...
This paper demonstrates a method for the detection and extraction of features like optic disc and macula from the retinal images. Digital fundus images are becoming popular for the diagnosis of ophthalmic pathologies. Due to this, there is an increasing possibility of applying digital image processing techniques and methods in these images to m the make the diagnosis more easier. In this paper first...
Nutrient status of a plant can be diagnosed by detecting the edges and veins of the leaf images since the deficiency symptoms are generally found in interveinal areas and along the edges. This paper proposes an effective algorithm for detecting the edges and veins in leaf images. The proposed algorithm was developed using Canny edge detection method. The algorithm provides accurate and positive results...
Transmission Control Protocol (TCP) is a predominant transport layer protocol for data transmission over internet. TCP being touted as the “protocol that saved the internet” due to its widely acclaimed congestion control algorithm, has started choking with the advent of challenges faced in the decentralized Multi-hop Ad Hoc Networks. Most notably, the burstiness of this congestion control mechanism...
