Eye movements are a continuous and ubiquitous part of sensory perception. To properly generate highly accurate and co-ordinate ocular movements, a vast network of brain areas are engaged, from low-level visual processing to motor control of gaze orientation. This renders oculomotor system vulnerable to various neurological disorders with unique clinical(More)

— Word sense disambiguation (WSD) is an open problem of natural language processing, which governs the process of identifying the appropriate sense of a word (i.e. intended meaning) in a sentence, when the word has multiple meanings. In this paper we introduce a new WordNet database relation structure whose usage enhances the WSD efficiency of(More)
Precision farming is basically designed to optimize agricultural inputs viz., fertilizers, pesticides, water etc., in tune with micro level/ field requirements. Optimization is focused on increased yields, reduced cost of cultivation and to minimized environmental impacts through location-specific management. Precision farming in the context of development(More)
The spectra of turbulent heat flux H(k) in Rayleigh-Bénard convection with and without uniform rotation are presented. The spectrum H(k) scales with wave number k as ∼ k −2. The scaling exponent is almost independent of the Taylor number Ta and Prandtl number Pr for higher values of the reduced Rayleigh number r (> 10 3). The exponent, however, depends on(More)
Neurological disorders often manifest themselves in the form of movement deficit on the part of the patient. Conventional rehabilitation often used to address these deficits, though powerful are often monotonous in nature. Adequate audio-visual stimulation can prove to be motivational. In the research presented here we indicate the applicability of(More)
Stroke is one of leading cause of death and disability worldwide. Early detection during golden hour and treatment of individual neurological dysfunction in stroke using easy-to-access biomarkers based on a simple-to-use, cost-effective, clinically-valid screening tool can bring a paradigm shift in healthcare, both urban and rural. In our research we have(More)
A stroke is caused when an artery carrying blood from heart to an area in the brain bursts or a clot obstructs the blood flow to brain thereby preventing delivery of oxygen and nutrients. About half of the stroke survivors are left with some degree of disability. Innovative methodologies for restorative neurorehabilitation are urgently required to reduce(More)
This paper describes the pattern recognition technique based on multiscale discrete wavelet transform(MDWT) and least square support vector machine (LS-SVM) for the classification of EEG signals. The different statistical features are extracted from each EEG signal corresponding to various seizer and nonsiezer brain functions, using MDWT. Further these sets(More)

In this paper we are proposing a text clustering method based on a well-known Word Sense Disambiguation (WSD) algorithm, the Lesk algorithm, to classify textual data by doing highly accurate Word Sense Disambiguation. The clustering of text data is thus primarily based on the context or meaning of the words used for clustering. The Lesk algorithm is used to(More)
