International Conference on Signal Processing, Embedded System and Communication Technologies and their applications for Sustainable and Renewable Energy (ICSECSRE '14) An Intelligent Acoustic Communication System for Aphasia Forbearings

ABSTRACT: Communication is a process of transferring the information from one entity to another. Speech is one of the most common modes of communication. The person who suffers from severe motor impairment, severe cerebral palsy, head trauma and spinal injuries cannot able to express their thoughts in the form of speech. The development of direct neurocontrol over virtual or physical devices would improve quality of life immensely for those who suffer from impaired communication skill. In this methodthe development of an Electroencephalogram (EEG) based Brain Computer Interface (BCI) system is proposed. The thoughts of the individual are extracted from the brain activity of a particular disordered patient and it is stored in the form of data.The word frequencies for basic essential requirements such as food, water and assisting work should be generated and the data is stored in matrix representation. Already obtained EEG signal and the word frequencies should be compared and the matched frequencies are stored separately. Finally, the matched frequencies of corresponding words are displayed using LCD display and then the words are converted into audible signal by using speech synthesizer

Determinants of acute lower respiratory tract infection in children aged 2 months to 5 years

Background: In India, acute lower respiratory tract infection (ALRI) is one of the major causes of death. During the year 2013, about31.7 million cases of ALRI were reported. Methodology: It is a prospective study in children aged from 2 months to 5 years whowere admitted to the hospital with clinical diagnosis of ALRI. A total of 100 children were included in the study. Results: About54% were incompletely immunized for age. 52% belonged to families falling under low socioeconomic status (SES). Leukocytosisis 41% and only 18% positive blood culture. There is significant association seen. Conclusion: The present study demonstratedthat there is significant association between the status of the immunization and SES with severity if pneumonia

Structural, magnetic and electric-polarization properties of geometrically frustrated YBaCo

In the RBaCo4O7 (R = Ca, Y and rare earth) cobaltite family, only CaBaCo4O7 shows 3D long-range ferrimagnetic and spin-driven electric-polarization properties. In the present study, we have investigated the structural, magnetic and electric polarization properties in YBaCo4O7 and DyBaCo4O7 members of this family and the obtained results are compared with the CaBaCo4O7. The compound YBaCo4O7 showed a series of magnetic transitions in agreement with the reported literature, additionally, a cluster glass behavior below 5 K is observed. Powder neutron diffraction studies on DyBaCo4O7 cobaltite showed an orthorhombic Pbn21 symmetry and signature of short-range 120° magnetic correlations of kagome layer and a spin glass behavior below 65 K. Dielectric measurements on both the samples showed strong frequency dispersion at high-temperature and frequency-independent behavior at low temperature without dielectric anomaly. Pyroelectric current measurement has showed a broad peak around 50 K in both the samples; however, a careful analysis relates the peak to thermally stimulated depolarization current. This study signifies that the giant structural distortions and cobalt charge ordering at the kagome layer are the key factors to drive both long-range magnetic ordering and spin-driven electric polarization in this cobaltite family
