Adapting Stream Processing Framework for Video Analysis

AbstractStream processing (SP) became relevant mainly due to inexpensive and hence ubiquitous deployment of sensors in many domains (e.g., environmental monitoring, battle field monitoring). Other continuous data generators (surveillance, traffic data) have also prompted processing and analysis of these streams for applications such as traffic congestion/accidents and personalized marketing. Image processing has been researched for several decades. Recently there is emphasis on video stream analysis for situation monitoring due to the ubiquitous deployment of video cameras and unmanned aerial vehicles for security and other applications.This paper elaborates on the research and development issues that need to be addressed for extending the traditional stream processing framework for video analysis, especially for situation awareness. This entails extensions to: data model, operators and language for expressing complex situations, QoS (Quality of service) specifications and algorithms needed for their satisfaction. Specifically, this paper demonstrates inadequacy of current data representation (e.g., relation and arrable) and querying capabilities to infer long-term research and development issues

Effect of Drip Fertigation on Growth, Yield and Quality of Ratoon Sugarcane

A field experiment was conducted at Zonal Agricultural Research Station, V.C. Farm, Mandya, Karnataka, India during Kharif 2020-21. The effect of water-soluble fertilizers on performance of ratoon sugarcane (Saccharum officinarum) as influenced by fertigation through surface drip irrigation was studied. The soil at the experimental site was red sandy loam with neutral pH (6.7), normal electrical conductivity (0.21dS m-1), medium organic carbon (5.2 g kg-1), low available nitrogen (275 kg ha-1), medium phosphorus (35 kg ha-1) and potassium content (280 kg ha-1). The experiment was laid out in Randomized Complete Block Design with three replications comprising seven treatments using VCF-0517 sugarcane mild late (12-14 months) maturing variety. The application of WSF at 125 per cent RDF (312.5:125:156:N:P2O5:K2O) through drip fertigation showed significantly superior growth and yield attributes viz., plant height (357.0 cm), no. of tillers clump-1 (15.0), internode length (16.67 cm), cane dry weight (54.8 t ha-1), millable canes (8.17 clump-1), cane length (341.67 cm), cane girth (3.30 cm), single cane weight (2.40 kg), number of internodes cane-1 (21.40) and cane yield (182.67 t ha-1). Also, superior juice qualities such as juice extraction percentage (70) and sugar yield (20.88 t ha-1) were recorded. The results clearly indicated application of water-soluble fertilizers at 125 per cent RDF through surface drip fertigation resulted in higher growth and yield of sugarcane due to enhanced water and nutrient use efficiency

Prevalence of genital prolapse symptoms in primary care: a cross-sectional survey.

INTRODUCTION AND HYPOTHESIS: The aim of our study was to determine the prevalence of pelvic organ prolapse (POP) symptoms in a community-dwelling population in the United Kingdom. METHODS: All women over the age of 18 from a community practice were sent the validated International Consultation on Incontinence Questionnaire for vaginal symptoms (ICIQ-VS), to determine their POP symptoms. Data were analysed as numbers (raw data) and percentages of responders. Statistical comparisons were made using Chi-squared and Kruskal-Wallis tests as appropriate. RESULTS: Questionnaires were mailed to 3,412 women, 1,832 completed questionnaires were received (response 53.7 %). Symptoms strongly associated with prolapse; vaginal bulge/lump and bulge or lump outside of the vagina had a prevalence of 8.4 % and 4.9 % respectively. Vaginal symptoms, previous pelvic floor surgery, and age were statistically increased in those who had had a previous vaginal delivery. There were statistically worse scores (more symptoms) for the group with any vaginal delivery with regard to "feeling a loose or lax vagina", "a vaginal lump or bulge coming down in the vagina". There was a high prevalence of worry regarding sexual function, regardless of delivery status, with no statistically significant differences found between those who had had a vaginal delivery and those who had not. The group with no vaginal deliveries described a statistically significant increase in the reported sensation of "do you feel your vagina is too tight". CONCLUSIONS: Symptoms of POP were increased in those women who had experienced a vaginal delivery, whilst the sensation of having a tight vagina was decreased in those who had had a previous vaginal birth
