Single Frame Image super Resolution using Learned Directionlets

In this paper, a new directionally adaptive, learning based, single image super resolution method using multiple direction wavelet transform, called Directionlets is presented. This method uses directionlets to effectively capture directional features and to extract edge information along different directions of a set of available high resolution images .This information is used as the training set for super resolving a low resolution input image and the Directionlet coefficients at finer scales of its high-resolution image are learned locally from this training set and the inverse Directionlet transform recovers the super-resolved high resolution image. The simulation results showed that the proposed approach outperforms standard interpolation techniques like Cubic spline interpolation as well as standard Wavelet-based learning, both visually and in terms of the mean squared error (mse) values. This method gives good result with aliased images also.Comment: 14 pages,6 figure

Concurrent Bursty Behavior of Social Sensors in Sporting Events

The advent of social media expands our ability to transmit information and connect with others instantly, which enables us to behave as "social sensors." Here, we studied concurrent bursty behavior of Twitter users during major sporting events to determine their function as social sensors. We show that the degree of concurrent bursts in tweets (posts) and retweets (re-posts) works as a strong indicator of winning or losing a game. More specifically, our simple tweet analysis of Japanese professional baseball games in 2013 revealed that social sensors can immediately react to positive and negative events through bursts of tweets, but that positive events are more likely to induce a subsequent burst of retweets. We also show that these findings hold true across cultures by analyzing tweets related to Major League Baseball games in 2015. Furthermore, we demonstrate active interactions among social sensors by constructing retweet networks during a baseball game. The resulting networks commonly exhibited user clusters depending on the baseball team, with a scale-free connectedness that is indicative of a substantial difference in user popularity as an information source. While previous studies have mainly focused on bursts of tweets as a simple indicator of a real-world event, the temporal correlation between tweets and retweets implies unique aspects of social sensors, offering new insights into human behavior in a highly connected world.Comment: 17 pages, 8 figure

Homoeopathic Management of Migraine in School going Children Based on Disease Intensity using Constituitional Remedies

BACKGROUND: Migraine is one of the common causes of severe, recurring headache; females are more commonly affects than males. The WHO considered the disability from living with a day of a migraine attack to be similar to living with a day of quadriplegia. However migraine can be cured with homoeopathic constitutional treatment. This study was done to evaluate the efficacy of homoeopathic treatment for migraine with constitutional remedies. METHODS: A clinical study on thirty cases with Migraine from age group of 12 to 17 years was done at Sarada Krishna Homoeopathic Medical College Hospital, Rural centres and School Heath programme. The study cases were selected purposively as per inclusion and exclusion criteria and diagnosis based on clinical presentation. Improvement criteria were based on the symptomatic relief according to scoring chart. RESULTS: The result of this study obtained that 28cases (93.3%) were markedly improved and 2 cases (6.6%) showed mild improvement. This result was based on statistical analysis of before and after treatment score. CONCLUSION: The result of the study shows that homoeopathic constitutional remedies are more effective in patients with migraine especially in children. Homoeopathy treats the patient as a whole and it reduces the intensity, prevents the frequent recurrence and thus improves the Quality of Life

Design and Synthesis of Peripherally Selective Endocannabinoid Enzyme Inhibitors for Ocular Indications

Peripherally selective compounds have been found to stimulate endocannabinoid receptor activity, which has been observed to have positive physiological effects such as ocular wound healing and inflammation control. The activation of the cannabinoid 1 receptor via binding of the endogenous ligands, anandamide and 2-arachidonoylglycerol, has been indicated to elicit these effects. Both ligands are controlled by two hydrolase enzymes, fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), which can be targeted for therapeutic inhibition. Sulfonamide derivatives of JZL195 containing carbamate functionalities in the southern region of the inhibitor compounds were produced using novel carbamate exchange reactions. Polar functionalities were introduced to increase their high topological surface area (TPSA) to prevent the crossing of these inhibitors through the blood-brain barrier (BBB), which in turn prevents any potential adverse effects on the central nervous system. The potency of each compound was measured using inhibitor screening assay kits for FAAH and MAGL

Investment facilitation: new dynamism at the WTO on investment

The proposal for an investment facilitation agreement has brought about a new dynamism on investment issues at the WTO. Unlike in the past, it is the developing countries and least developed countries who champion the discussions. They hold that trade and investment policies are inseparable

D evelopment and Testing of a Closed Loop Feedback Controlled Magnetorheological Fluid Anti-vibration Mount for Onboard Naval Applications

An intelligent semi-active anti-vibration mount using a magnetorheological (MR) fluid is designed and developed for onboard applications. The mount consists of a load bearing elastomer, MR fluid chamber; MEMS based vibration sensor and a controller for closed loop feedback mechanism. The controller regulates the solenoid current in the MR fluid chamber, which in turn regulates the flow of MR fluid through the valve. Comparison of the performance of MR mount with a passive resilient rubber mount shows that the former provides 7 dB extra damping at resonance compared to the later and the isolation of MR mount starts at 10 Hz compared to 50 Hz by rubber mount. This mount can operate in real time, passive and active modes by using a closed loop feedback control mechanism. The efficacy of the mount for outdoor applications is evaluated by characterizing the mechanical, environmental, electrical and electromagnetic properties as per MIL-17185, JSS-55555 and IEC 61000 standards and found to be superior compared to passive mounts. The mount is being evaluated for onboard applications in INS Ranvijay
