Video Resolution Enhancement using DWT, SWT and CLAHE

One of an image details which has been always an vital concern in various image and video-processing applications, such as video resolution enhancement, feature extraction, and satellite image resolution enhancement is resolution. In recent advances Video Resolution enhancement has been envisioned to help in numerous applications and has turned out to be a hot research area. This opens up several technical challenges and immense application possibilities. The paper describes the three main categories - Contrast limited adaptive histogram equalisation (CLAHE), Discrete Wavelet Transform(DWT), Stationary Wavelet Transform(SWT). DWT uses filter for building the multi-resolution. SWT is an extension of the Standard Discrete Wavelet Transform to enhance the general details of an image. This study presents a novel resolution enhancement methods with future research are

Extent of Empowerment of Women Entrepreneurs on Entrepreneurial and Technological Empowerment

Empowerment of women entrepreneurs in the context of technology entails building up the abilities and skills of women to gain insight into the issues affecting them and also building up their capacity to voice their concerns. Technological empowerment of women entrepreneurs will open up avenues to further nrichment. By the use of technology women can broaden the scope of their activities. Hence the present paper focused on analyzing the entrepreneurial and technological empowerment of women entrepreneurs. Majority of the women entrepreneurs had medium level of entrepreneurial and low level of technological empowerment

Effect of Bandwidth Scalability on System Performance in the Downlink LTE Systems

Long Term Evolution (LTE) system employs Orthogonal Frequency Division Multiple Access (OFDMA) in downlink in order to support network deployment using various system bandwidth configurations i.e., 1.4MHz, 3MHZ, 5MHz, 10MHz, 15MHz and 20MHz. The bandwidth scalability enables operator to access multiple channels to achieve higher peak data rates. Also, the bandwidth scalability allows operators to deploy LTE network with the existing spectrum or newly licensed band. Therefore the study on performance of LTE system with different bandwidth configuration becomes vital. Hence in this paper, an attempt has been made to study and compare the performance of LTE system with different spectrum configuration i.e., 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz for Constant Bit Rate (CBR) traffic scenario in the downlink. The performance metrics considered for simulation studies are aggregate bytes received, average throughput, average delay and average jitter

Automated Identification of Oceanic Fronts for Operational Generation of Potential Fishing Zone (PFZ) Advisories

PFZs, are essentially the frontal structures as identified from the satellite images of Sea Surface Temperature (SST) and chlorophyll concentration. These regions are known for fish aggregation and provide cost-effectiveness in offshore fishing operations. Subjective identification of fronts may lead to human-errors, non-negotiable beyond a limit. To overcome this, we propose utilization of tools that help automated identification of the frontal structures. This approach not only removes the errors, but also helps shorten the time period of the operational process-chai

A Survey on Data control from sender using cloud computing

To store data more efficiently in cloud security must also be taken into considerations. When certain information is stored in Cloud, it actually means that it resides outside an organization's structure bounds. This results in loss of data and information which leads to low cost security issues that, reduces adoption of Cloud computing techniques. This paper surveys mainly on data-centric access control with enriched role-based quality focusing security as a target, protecting user information despite the Cloud service provider that holds it. It also deals with identity based encryption and proxy re-encryption techniques to protect the authorization model

Following tagged Yellowfin tuna along the east coast of India explains its feeding behavior: a case study in the Bay of Bengal

Horizontal movement of pelagic fish predator, Yellowfin (Thunnus albacares) tuna, in the oceanic waters of Bay of Bengal has been decoded. Pop-up Satellite Archival Tags (PSATs) were attached to adult tunas to study their distribution and migration. For this, environmental satellite data were matched with the tag locations to understand and characterize habitats of this species. A sub-set of the tag data was selected corresponding to the maximum resident time of tuna indicated by a high density data points. The tagged tuna spent 60 to 70% of its time in the waters having surface temperature within 28o to 29.5oC and sea surface height anomaly within+5 to +12 cm. The tag positions were located on the satellite images; chlorophyll, sea surface temperature, zooplankton and sea surface height anomaly. The two conditions, specific range of temperature and prey abundance, were found necessary for aggregation of tuna

Utility of Sea Surface Height anomaly (SSHa)in determination of Potential Fishing Zones

Physical processes in the oceans can be monitored by altimeters well before a radiometer can in terms of temperature or chlorophyll concentration. Herein we show the importance of Sea Surface Height anomaly (SSHa, retrieved with altimeter) in demarcating potential fishing zones. We also show how SSHa can help predict tuna movements, horizontally as well as vertically in the water column. Moreover, we prove these prediction with positively correlating SSHa to tuna hooking rates. In the end, we list out present and potential future sources from where SSHa can be retrieved in order to provide improved fishery advisories

A Review On Omaveloxolone

Omaveloxolone is a semisynthetic triterpenoid used to treat friedreich’s ataxia. It is the second generation oleananetriterpenoid Nrf2 inducer with antioxidant and anti-inflammatory properties. It is currently used to test in medical trials for freidreich’s ataxia, a genetic, multi –organ disease involving mitochondrial dysfunction. It is a nuclear factor erythroid 2 related factor 2 (Nrf2) activator. It is reviewed under Food and Drug Administration and it has the potential to first approved treatment for friedreich’s ataxia. Omaveloxolone is not the cure for friedreich’s ataxia, it is the first agent targeting to reach NDA submission. It is the rational and potent therapy that is probably disease modifying in the treatment of friedreich’s ataxia. Omaveloxolone (RTA-408) is an Nrf2 activator, which decreases the susceptibility of cells through oxidative stress and it leads to cell death and tissue degradation. It is good tolerated not having any significant long term adverse effects. Treatment with RTA-408 remarkably improved in the neurological function, it is measured by modified Freidreich’s Ataxia Rating Scale

Laxative Property of Safoof-E-Sana, a Unani Formulation

An investigation was carried out to study the laxative property of aqueous extract Safoof-ESana in the unani formulation. Aqueous extract of Safoof-E-Sana was evaluated for laxative property and was measured by weighing the fecal out at 8th and 16th hour of drug administration. Safoof-E-Sana at 50, and 100 mg/kg showed dose dependent laxative effect. The results are compared with standard Senna. Safoof-E-Sana was showed significant laxative activity
