Semi Supervised Video Object Mining Framework to Multiple Object Extraction

Video mining using combination of supervised and unsupervised learning techniques has created an arc in multimedia data mining. With this binding (usual & unusual mining) technique, today we can get accurate results in multimedia applications. This blend takes away the formal techniques that were used in video mining. Though video mining in general it is purely unusual mining, there exists some complex computational work by all means. Hence this work first compares the efficiency in video mining between unsupervised and semi-supervised learning techniques and then proposing a model or framework for multiple object extraction. In Multimedia Mining multiple object extraction is one of the challenging areas. This is because it contains more critical issues and it is a complex task when it comes to dynamic applications. Hence an attempt is made with some assumptions to extract multiple objects using semi supervised learning techniques. This proposed model blends semi supervised learning techniques and multiple object extraction with necessary compression and decompression methods in a simple way as an initial step to address the two challenging areas of video mining

Magnetoresistance of metallic perovskite oxide LaNiO3−δ_{3-\delta}

We report a study of the magnetoresistance (MR) of the metallic perovskite oxide LaNiO$_{3-\delta}$ as a function of the oxygen stoichiometry $\delta$ ($\delta \leq$ 0.14), magnetic field (H $\leq 6T$) and temperature (1.5K $\leq$ T $\leq$ 25K). We find a strong dependence of the nature of MR on the oxygen stoichiometry. The MR at low temperatures change from positive to negative as the sample becomes more oxygen deficient (i.e, $\delta$ increases). Some of the samples which are more resistive, show a resistivity minima at $T_{min}$ $\approx$ 20K. We find that in these samples the MR is positive at T > $T_{min}$ and negative for T < $T_{min}$. We conclude that in the absence of strong magnetic interaction, the negative MR in these oxides can arise from weak localisation effects.Comment: 10 pages in REVTeX format, 4 eps fig

REVIEW OF PULMONARY EMBOLISM

Pulmonary embolism is a blockage of main artery or one of its branches of lung by the fat, amniotic fluid, embolisation of air or any other foreign substances. It is also due to formation of thrombus [blood clot] in the arteries of lung. Due to the pulmonary embolism the blood circulation in the body will be effected. Sometimes PE leads to death also by the lacking of breathing. In USA the annual incidence rates per 1000 persons aged 65-69 are 1.3 affected by pulmonary embolism. The diagnosis of pulmonary embolism at the earlier stage will be difficult because the symptoms like difficulty in breathing and chest pain are not easily differentiated from the other diseases like myocardial infarction. The usage of drugs like anti coagulants and thrombolytic cause bleeding problems even though they shows the antagonistic activity of pulmonary embolism at higher doses. Physician responsibility is to successfully avoid bleeding disorders are at the time of prevention of pulmonary embolism. And also by conducting of programs which should strive to coordinate care, by region wide guidelines and by implementing of care programs there is a chance to elaborate knowledge about the pulmonary embolism to the physicians and also there is a chance to bring awareness among the public which may decreases the number deaths due to pulmonary embolism annually. KEY WORDS: Pulmonary embolism, myocardial infraction, intra vascular co agulation, e.t.c

Thematic and Stylistic Analysis of Maya Angelou Poems: A Review of Literature

Poetry is a form of creative art, through which many writers express their emotions, feelings, and also their bitter experiences to the world. Poetry, along with autobiography helped in the revelation of self, especially among African-Americans. Black women writers, in particular, have experienced many trials and tribulations while struggling for identity and freedom in the land of America. As women were considered inferior since the early period, their writings reflect deeply on their life stories and create a positive self-identity. Qualitative descriptive method is commonly used in the reviewed articles. This article examines the existing research on Angelou’s poems with the explored areas such as racism, gender issues, figurative analysis, feminism, stylistics, etc., and identifies the characteristics of self-portrait in them

Uncertainties in the Measurements in Differential Scanning Calorimeter and Thermomechanical Analyser

Reproducibility of the output signal in Differential Scanning Calorimeter has been examined in detail. The ordinate calibration factor has been found to diminish at higher temperatures. Calibration factor for enthalpy output has also been evaluated. A procedure for calibrating the area by the proper selection of the base-line for both scanning and isothermal modes of operation has been described. This factor has largely been ignored in the papers published so far. And also the assessment of the performance of Thermomechanical analyser has been done by using AI as expansion standard varying heating rate, sensitivity and load. A simple method for the determination Youngs modulus at room temperature using TMA is also given

FAST DISSOLVING SUBLINGUAL PATCH OF PHENOBARBITAL SODIUM: FORMULATION AND IN VITRO EVALUATION

Objective: To formulate and characterize. Phenobarbital sodium loaded sublingual patch using biodegradable, mucoadhesive, fast-dissolving natural polymer pullulan for immediate management of epileptic seizures. Methods: Phenobarbital sodium loaded sublingual patches were prepared by the solvent casting method and were subjected to various physicochemical evaluation parameters to find the optimized sublingual patch. The&nbsp;in vitro&nbsp;drug release study and&nbsp;kinetic model of the optimized formulation was also carried out. The stability study of the optimized Phenobarbital sodium loaded sublingual patch was also done. Results: From in vitro drug release study, it was found that Phenobarbital sodium loaded sublingual patch (S4) exhibited a maximum drug release of 96.24±1.27% at the end of 60 min compared to other formulations indicating a faster drug release from the formulation with release kinetics as Higuchi diffusion model. In fact, a notable release data was obtained between 0.5 to 8 min by all formulations, specifically S4 formulation (20.84±1.97% and 77.22±2.41% drug release at the end of 0.5 min and 8 min respectively) showed a better percentage release profile in comparison with other formulations. Such a trend is vital to deliver the drug at a faster rate to promote immediate effect for managing the fatal and complicated seizure. Considering the physicochemical property and in vitro drug release data, S4 formulation was regarded as an optimized one. The stability study also confirmed that S4 formulation is stable at refrigeration conditions. Conclusion: The formulated Phenobarbital sodium loaded sublingual patch is an effective drug delivery carrier which enables faster drug release to manage epileptic seizure
