GUI system for Elders/Patients in Intensive Care
In the old age, few people need special care if they are suffering from
specific diseases as they can get stroke while they are in normal life routine.
Also patients of any age, who are not able to walk, need to be taken care of
personally but for this, either they have to be in hospital or someone like
nurse should be with them for better care. This is costly in terms of money and
man power. A person is needed for 24x7 care of these people. To help in this
aspect we purposes a vision based system which will take input from the patient
and will provide information to the specified person, who is currently may not
in the patient room. This will reduce the need of man power, also a continuous
monitoring would not be needed. The system is using MS Kinect for gesture
detection for better accuracy and this system can be installed at home or
hospital easily. The system provides GUI for simple usage and gives visual and
audio feedback to user. This system work on natural hand interaction and need
no training before using and also no need to wear any glove or color strip.Comment: In proceedings of the 4th IEEE International Conference on

Controlling a remotely located Robot using Hand Gestures in real time: A DSP implementation
Telepresence is a necessity for present time as we can't reach everywhere and
also it is useful in saving human life at dangerous places. A robot, which
could be controlled from a distant location, can solve these problems. This
could be via communication waves or networking methods. Also controlling should
be in real time and smooth so that it can actuate on every minor signal in an
effective way. This paper discusses a method to control a robot over the
network from a distant location. The robot was controlled by hand gestures
which were captured by the live camera. A DSP board TMS320DM642EVM was used to
implement image pre-processing and fastening the whole system. PCA was used for
gesture classification and robot actuation was done according to predefined
procedures. Classification information was sent over the network in the
experiment. This method is robust and could be used to control any kind of
robot over distance
Groundnut its nutrition and fertilizer responses in India
THE cultivated groundnut Arachis l~ypogaea L, originated in South
America and is now grown in 82 countries in the world and India is the largest
producer of the crop. India, China, Nigeria, USA and Senegal account
for four-fifths of the world's groundnut production. Groundnut was
introduced in India in the 16th century. The area under the crop, however,
was rather small till the beginning of the present century. being around one
lakh hectares. It increased progressively to 6 lakh hectares by the end of
the First World War and to 45 lakh hectares by 1950.........

Identification of MS-specific serum miRNAs in an international multicenter study.
ObjectiveTo identify circulating microRNAs (miRNAs) linked to disease, disease stage, and disability in MS across cohorts.MethodsSamples were obtained from the Comprehensive Longitudinal Investigation of Multiple Sclerosis (CLIMB, Boston, MA), EPIC (San Francisco, CA), AMIR (Beirut, Lebanon) as part of the SUMMIT consortium, and Stockholm Prospective Assessment of Multiple Sclerosis (Stockholm, Sweden) cohorts. Serum miRNA expression was measured using locked nucleic acid-based quantitative PCR. Four groups were compared: (1) MS vs healthy control (HC), (2) relapsing-remitting (RR) vs HC, (3) secondary progressive (SP) vs HC, and (4) RR vs SP. A Wilcoxon rank-sum test was used for the comparisons. The association between each miRNA and the Expanded Disability Status Scale (EDSS) score was assessed using the Spearman correlation coefficient. For each comparison, the p values were corrected for multiple comparisons using the approach of Benjamini and Hochberg to control the false discovery rate.ResultsIn the CLIMB cohort, 5 miRNAs (hsa-miR-484, hsa-miR-140-5p, hsa-miR-320a, hsa-miR-486-5p, and hsa-miR-320c) showed a significant difference between patients with MS and healthy individuals; among these, miR-484 remained significant after accounting for multiple comparisons (p = 0.01). When comparing RRMS with HCs, hsa-miR-484 showed a significant difference (p = 0.004) between the groups after accounting for multiple group comparisons. When SP and HC were compared, 6 miRNAs (hsa-miR-484, hsa-miR-140-5p, hsa-miR-142-5p, hsa-miR-320a, hsa-miR-320b, and hsa-miR-320c) remained significantly different after accounting for multiple comparisons. Disability correlation analysis with miRNA provided 4 miRNAs (hsa-miR-320a, hsa-miR-337-3p, hsa-miR-199a-5p, and hsa-miR-142-5p) that correlated with the EDSS during the internal reproducibility phase. Among these, hsa-miR-337-3p was the most statistically significant miRNA that negatively correlated with the EDSS in three of the MS cohorts tested.ConclusionsThese findings further confirm the use of circulating serum miRNAs as biomarkers to diagnose and monitor disease status in MS.Classification of evidenceThis study provides Class III evidence that levels of circulating miRNAs identify patients with MS
