Background: Good postural stability is required for the integrated functions of visual, somatosensory and vestibular system. But there is a less evidence related to limits of stability variations under different sensory conditions in young adult women by using swaymetre. Objective: The objective of this study is to analyze the variations in limits of stability under different sensory conditions among young adult women.Methods: A total of 15 female subjects of age group between18-22 were selected based on convenient sampling. All participants were exposed to different sensory conditions for assessing the steadiness and maximum balance range by using swaymetre. These parameters were measured both in A-P and M-L directions. The study was conducted in PSG Evidence-based Neuro Rehabilitation Centre, Department of Neurological Physical Therapy, PSG Hospitals, Coimbatore. Mean difference of steadiness and maximum balance range was used as statistical stool.
Results: The values obtained as mean differences of steadiness and maximum balance range with eyes open and eyes closed in A-P and M-L directions on flat and foam surfaces were real data. Obtained values of steadiness and maximum balance range were mentioned. The mean differences of steadiness with eyes open in A-P and M-L directions on flat and foam surfaces were 13.54mm & 14.60mm and with eyes closed are 49.07mm & 55.33mm respectively. The mean differences of maximum balance range with eyes open in A-P and M-L directions on flat and foam surfaces were 31.06 & 54mm and with eyes closed are 2.13mm and 49.53mm respectively. The mean differences of steadiness in A-P and M-L directions on flat surface with eyes open and eyes closed were 2.6mm and 2.14mm and on foam surface with eyes open and eyes closed were 38.13mm and 42.93mm respectively. The mean differences of maximum balance range in A-P and M-L directions on flat surface with eyes open and eyes closed were 20.06mm & 10.5mm and on foam surface with eyes open and eyes closed were 10.13mm and 6mm respectively.
Conclusion: Vision, Proprioception and Vestibular system play a major role in maintaining the postural stability under different sensory conditions. This study recommends the obtained values for the limits of stability under different sensory conditions for women using swaymetre can be used as a baseline value for further studies.

An experiment was carried out to assess the crop loss due to sunflower leaf curl virus (SuLCV) disease. The crop loss assessment in terms of growth and yield components was recorded at first appearance of symptoms of SuLCV at 30 days to 90 days during the crop growth. The SuLCV disease infection in sunflower significantly affected the plant height (72.60 to 157cm), size of the head (8.60 to 18.78cm), 100 seed weight (2.20 to 6.32g), oil content (31.24% to 38.26%), and weight of seeds/10 heads (77.20 to 372.2g) as compared to the healthy control plants. In the plants, first appearance of symptoms at 30 DAS was recorded the seed yield loss of 79.25 per cent.Keywords

Digital Systems can be designed using Hardware Descriptive Languages. Digital System Design is one of core subject for fifth semester students of Electronics and Instrumentation Engineering, Siddaganga Institute of Technology, Tumakuru. Outcome Based Education is the main objective of curriculum. The outcome of course was, at the end of the course students were able to write code in VHDL for any given digital system, simulate on Xylinx CAD tool and Implement on Spartan 3 FPGA kit. To support the students, to enhance the skills and share their work, an Open Education Resource(OER) with name digital system design blog at WordPress was created. This platform helps students and teaching community associated with digital system design course. The platform includes blog and pages. The blog gives brief introduction about the course. The pages are dedicated to theory, lab, question bank, students' assignment, videos and Feedback page. All of their work was shared on WordPress platform digital system design blog. This covered the maximum examples from the course which was very helpful to students. This Open Education Resources is licensed under Creative Commons licence CC-BY-SA4.0. The videos created in YouTube are also under Creative Commons license. So anybody can share, redistribute and modify the work for further improvement. Creating an Open Education Resource for outcome based subject enables new blended teaching methods to be adopted in engineering education.WordPress is the one of the free resource that can be effectively utilized as platform to share the resource at global level. The survey was conducted among the students of fifth semester and they found that videos were very useful. The feedbacks reflected that website can improved with subjective and objective quizzes.Keywords

DDoS attacks in MANETs needs to be handled as early as possible so as to avoid them to reach the victim node. DDoS attacks are difficult to detect due to their features like varying attack intensity, large amount of packets etc. so it becomes necessary to distinguish and filter attack traffic in source or intermediate clusters. Here the cluster heads will uses flow based monitoring schemes to identify the suspicious behaviours of incoming traffic in each clusters. Cluster head constructs flows from the incoming traffic and computes normalized entropy for specific time windows. The normalized entropy is compared against threshold entropy to identify the presence of suspicious flows. Later packet rate of suspicious flow is calculated and compared against packet rate entropy to identify the suspicious flows. Later the suspicious flow information is shared with neighbouring cluster heads to further confirm the presence of DDoS attack or not. If DDoS attack is confirmed the packets related to suspicious flows will be discarded. The efficiency and accuracy of proposed attack detection algorithm is evaluated using some performance metrics.Keywords
