Abstract :

Due to absorption and scattering of underwater the images obtained suffers an information loss. The study of underwater is very important to find the unfound many algorithms have been derived to enhance an underwater image but no method gives a clear vision of human eye. Many methods found suffers a disadvantage that the clarity reduces as the depth of the water increases this is due to the fading of colours in underwater. To solve this problem, we get into a non-reference underwater image enhancement method the UICCS method. The three main attributes of an image are its colour contrast and sharpness. In this method we modify the attributes of the image step by step to attain a clear image. The results of this experiment demonstrate clearly that this method produces an output image with a high information the measures are applied to underwater images to show their importance in practical application. This project solves this problem my a simple and easy methodology with changing the three main attributes of an image thus enhancing the information of the image.

Abstract :

The present study is based on the Blended Learning (B-learning) method using the Project Based Learning (PBL) as a teaching strategy. The students’ performance can be valued through face- to- face sessions and on-line interactions when they created business projects as an approach to real situations of business life. To carry out this study, the students use the Canvas model, as a systematic prototype integrated by nine interrelated blocks that enable the comprehension about the different activities to follow for the creation of a business model in a holistic and simple way. As a result of this mixed study, it was found out that the professors make the most effective contribution to B-learning. This is due to the fact that they are in charge of the coordination, organization and planning of the teaching-learning process in general. They have to look for the best teaching strategies and technological resources to achieve their educational aims. Throughout the course, the professor’s role is to motivate the student in order to make a final product which can connect his/her educational activities with real life situations. Meanwhile the student is carrying out the project, he needs to solve complex problems.

Abstract :

There are many image-guiding systems which provide a surgeon with surgical information including location or orientation of tools and bodies such that they helps the surgeon monitor the surgery during the operation. But these image-guiding systems may suffer from imaging distortion due to their mechanical deformations. Therefore, it is needed for the systems to preserve their good localization ability with the calibration process in which the precise radio-projection geometry is determined for X-ray image. But, it is very difficult to reduce deformation error with calibration of the imaging system because of its high complexity of mechanical model. So, in this paper, we suggested a simple calibration method based on a series of laser images, which can be applicable to on-line calibration procedure.

Abstract :

Backgroud: The relationship between resistant hypertension (HAR) and sodium remains controversial. This study aimed to evaluate the relationship between resistant hypertension and urinary sodium and potassium excretion. Methods: It is a cross-sectional study. Socio-demographic, clinical and laboratory variables were evaluated. The estimated consumption of Na + and K + in 24 hours was determined by the formula of Kawasaki & Tanaka (2002) and defined as high for Na +> 4g, and potassium> 4.2g. Results: Fifty-one patients with HAR were evaluated. Sodium intake increased by 56% and was associated with HAR in patients with: age between 40 and 65 years (OR = 14.91, 95% CI 1.37-162.07); Potassium intake> 4.2g (OR = 8.27; 95% CI: 1.12- HYPERLINK "call to: 1.12% 20-% 2061.16" 61.16) and Caucasians (OR = 23.17; 95% CI 1.23-147.85). High potassium intake was negatively associated with uncontrolled HAR, and this association was at the threshold of statistical significance for patients with daily sodium intake of less than 4 g (OR = 0.05, 95% CI 0.01 - 1.00). Conclusion: It was observed an association between adequate blood pressure control and HAR and uncontrolled with high potassium excretion and low sodium in patients with lower age and Caucasians. The result of the present study suggests a distinct relationship of sodium and potassium among patients with resistant and uncontrolled hypertension, observed in studies investigating this association with systemic arterial hypertension.

Abstract :

The current research work presents one-dimensional numerical simulation results of water surface elevation along a natural river, in order to investigate an accurate operation of three existing dams, with flat and arched gates, for flood protection. The study reports an extensive numerical simulation procedure of four different operations of the dam gates, including all gates opened, all gates closed, only flat gates opened and only arched gates opened, for flood risk estimation through the studied river reach. The one-dimensional hydrodynamic numerical simulation procedure of water surface profile variation, under steady flow conditions, through the natural river, was performed for available maximum inflow discharges of 5, 25 and 100 year flood period.

All numerical results are graphically presented and comparisons between different gate operations provide an accurate investigation of a safe dam handling in order to prevent the surrounding river area against flood events. The applied hydrodynamic numerical model, “HEC-RAS” model, is a useful and accurate methodology for flood risk assessment in a natural river area, with complicate geometries and different hydraulic constructions.

Abstract :

We show how Newtonian gravity with effective (actually observed) masses, obeying the mass-energy relation of special relativity, can explain all observations used to test General relativity. Dynamics of a gravitationally coupled binary system is considered in detail and the effective masses of constituents are determined. Interpreting our results in terms of motion in a curved space-time background, we are led, using the Lagrangian formalism, to consider the exponential metric as a natural space-time metric of Newtonian gravity.

Abstract :

Modern civilization is driven mainly by electricity and hence a reliable and secure power system plays a vital role. One very important aspect of this vital system is stability. Over the years generations of power engineers studied the stability aspects and a lot of research was conducted and methods of maintaining the stability of this highly nonlinear distributed system of very high order are suggested. One of the developments over the years is use of supplementary signals to keep the system dynamically stable over a wide range of operating conditions. In power system parlance, this is called power system stabilizer (A controller). Various classical and modern control theory techniques are used to design power system stabilizers. This work address the problem of designing a power system stabilizer for a Single Machine Infinite Bus (SMIB) system. The SMIB is modelled as a fourth order system and the Power System Stabilizer (PSS) is designed using PID controller using Particle Swarm Optimization technique. The results obtained are compared with stabilizers designed using phase lead compensator and a PID controller using Ziegler-Nichols method. Comparison made for a small disturbance in the mechanical torque, for a wide range of operating conditions, to ensure robustness of the controller. The responses are generated using MATLAB-SIMULNK software.

Abstract :

The ankle-brachial index (ABI) has been used to identify peripheral arterial occlusive disease and is a marker of macrovascular complications in patients with hypertension.  The objective of the present study was to investigate factors associated with an abnormal ABI in patients with resistant hypertension.  A cross-sectional study with a consecutively selected sample was conducted in a referral cardiology outpatient clinic in Salvador, Bahia, Brazil.  Sociodemographic, anthropometric, clinical, laboratory and echocardiographic data were collected.  The association between abnormal ABI and possible risk factors was evaluated using odds ratios (OR), with their respective 95% confidence intervals (95%CI).  Next, logistic regression analysis was performed, using a hierarchical model.  The prevalence of an abnormal ABI was 19.0%.  Most patients were female (74.8%), black (57.1%), overweight or obese (85.8%), of 40-65 years of age (60.3%), and with education above primary school level (63.8%).  In addition, 44.0% were diabetics; 29.9% had hypercholesterolemia, 21.9% had hypertriglyceridemia and 18.1% had had a cerebrovascular accident.  The factors that remained significantly associated with abnormal ABI in the final model were diabetes (OR=4.11; 95%CI: 1.10-15.50), age >65 years (OR=3.30; 95%CI: 1.13-9.69) and hypercholesterolemia (OR=4.18; 95%CI: 1.12-15.58).  The prevalence of abnormal ABI, albeit not as high as in groups of patients with specific pathologies, was found to be significantly associated with the risk factors traditionally described in the literature.  Therefore, the ABI should be used routinely to evaluate patients with severe hypertension as a method of screening for vascular alterations.

Abstract :

Public distribution system i.e rationing distribution is one of the widely controversial issue that involves corruption and illegal smuggling of goods. One reason of this to happen is because every job in the ration shop involves manual work and there is no special technology involved in automating the job. Involvement of manual work calls a lot of irregularities. These irregularities or illegal activities are for example - wrong entries in stock register of shop containing wrong stock information of the products that is supplied to the public, sometimesthere are chance of distribution of low quality/graded products than the actual products provided by the Government for supplying to the public, also the information regarding the actual available stock quantity in a ration shop that is provided by the Government to the public. In this paper we propose the concept of replacing manual work/job in public distribution system (rationing distribution system in India) by automated system which can be installed at the ration shop with ease. In this automated system we replace the conventional ration card by smart card in which all the details about users are provided including their AADHAR (social security) number which is used for user authentication. This prompted us to interface smart card reader (RFID Based) to the microcontroller (AT89C51) and PC via RS232 to develop such a system. Using such a system, Government would have all required control/monitoring over the transactions at ration shop. To involve Government in the process we proposed connecting the system at ration shop to a central database (provided by Govt.) via GSM module (SIM900D) and RS232. Hence it is possible to pre-vent the corruption and irregularities at ration shop. This would bring the transparency in public distribution system as there will be a direct communication between people and Government through this.

Abstract :

We studied the motion of a spin onehalf particle in a singular spacetime metric of exponential type. This singular spacetime metric is obtained from a particular interpretation of the Newtonian gravitational force. For a given energy, the motion of a particle is described by the eigenvalue modes of the Dirac operator in a singular space time metric of exponential type. In this paper only the first order solution is considered leading to a cubic algebraic equation for energy eigenvalue. A novel interpretation for a gravitational atom is obtained.

Abstract :

In this research, a multi-functional copolymer assembled with superparamagnetic iron oxide nanoparticles (SPIONs) were prepared via a simple assembly process for targeting delivery of doxorubicin (DOX) and magnetic resonance (MR) imaging detection. The multi-functional copolymer, polyamidoamine (PAMAM), was synthesized by Michael addition reaction, where N,N-Bis(acryloyl) cystamine served as cross-linker, DOX, dopamine (DA), folic acid–polyethylene glyco (FA-PEG) and PEG acted as comonomers. Here the PAMAM is directly assembled to the surface of SPIONs by the ligand exchange reaction with SPIONs forming the drug loaded biodegradable magnetic nanoparticles (MNPs-DOX). The hydrophilic PEG moiety provides the nanoparticles colloidal stability and good-dispersity in aqueous solution. Colloidal stability of the MNPs-DOX in aqueous media by their anti-fouling property. TEM images showed that the MNPs-DOX were well dispersed with high stability in water after the ligand exchange process. All the results showed that the prepared biodegradable magnetic nanoparticle could serve as a promising vehicle for targeting anticancer drug delivery and efficient detection through MR imaging in theranostics.

Abstract :

Background: Despite improvements in diagnostic medicine the accuracy diagnosis of acute appendicitis in several cases is yet difficult. Methods: 76 patients were admitted in the hospital for possible acute appendicitis. White blood cells count (WBC) measurement and C-reactive protein (CRP) were assessed in all patients. Of 76 patients, 62 (81%) were operated on by the diagnosis of acute appendicitis, 2 (3%) were operated on without diagnosis of acute appendicitis and served as a control group, and the remainder 12 patients remained under observation, were finally not operated on and served as controls, too. The 64 patients, who were managed by appendicectomy, were divided in four groups proportionally to the operative findings and histopathological reports. Each group’s laboratory tests were investigated for WBC and CRP elevation and sensitivity and specificity of these tests were also estimated .

Results: The sensitivity and specificity of these tests were 69% and 71% for neutrophil count and 87% and 100% for CRP, respectively. Conclusion: Thereby, patients with normal results in all tests (CRP and WBC) together are unlikely to have acute appendicitis, but it is not absolute and that is why should be evaluated with greater caution.
