Real-time surveillance is a vital component in any situation or environment where there is a high need of security for both personal and commercial property and assets. Technology today is used in many different ways in order to provide us such surveillance. An ideal solution for surveillance involves not only the assortment of necessary sensors and devices using appropriate tools, but also should be provided in the most optimized way for obtaining feed and data while keeping the expenditure minimized. In our project, we aimed at developing a low-cost, real-time video surveillance mini-rover which will be capable of providing real-time video footage and roam around in the area which we want to observe. Our target was to use hardware which is very low of cost and easily available.
The aim of this investigation was to determine the reliability of normalizing rapid force (RF) production to peak force assessed during an isometric knee flexor assessment, and to present a novel method of classifying athletes' potential training needs within the 90À90 isometric hamstring assessment. Procedures: Twenty elite female soccer players (age: 20.7 § 4.7 years; height: 168.2 § 5.5 cm; body mass: 62.8 § 7.0 kg), with no recent (>6 months) history of hamstring strain injury, volunteered to participate in the study. Following a standardized warm-up, each participant performed three maximal isometric hamstring contractions, with their heel resting on a force plate, elevated on a box, to ensure that their hips and knees were at 90°Data was analyzed to determine peak for (PF), RF was established as force expressed at 100 ms (F100) and force expressed at 200 ms (F200), with force at each time-point subsequently normalized to a percentage of PF. Findings: F100 and F200 normalized to PF demonstrated good absolute reliability (%CV = 6.12À7.62) and moderate relative reliability (ICC = 0.689À0.703). Concurrently observing PF and normalized F100 and F200 could provide clear training and monitoring goals. Conclusions: Normalizing measures of RF production, including F100 and F200, to PF can be performed reliability. Therefore, could be tracked overtime to identify changes as an effect of training or for fatigue monitoring purposes. However, further research is required to determine how knee flexor force-time characteristics change in relation to focused training and how these characteristics change in response to fatiguing activities.
Live audio-video streaming has become popular over the years especially when it comes to communication between people living huge geographical areas apart and at a very cheap rate or even free. However, when it comes to places where bandwidth is low or limited, smooth streaming has become a serious challenge because after all bandwidth is a natural resource and is limited. Therefore, in this paper we present two algorithms or 'network streaming codecs' that are designed for compressing live multimedia streams to considerable levels of 25% and 50%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
