Implementation of Decision Based Algorithm for Median Filter to extract Impulse Noise
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: This paper presents an accurate and efficient noise detection and filtering algorithm for impulse noise removal. The algorithm includes two stages: noise detection followed by noise filtering. The proposed algorithm replaces the noisy pixel by clipping median value when other pixel values, 0’s or 255’s are present in the selected window and when all the pixel values are 0’s and 255’s then the noise pixel is replaced by mean value of all the elements present in the selected window. Even at high noise densities this algorithm gives better results in comparison with other existing approaches. The proposed algorithm is tested & compared for different grayscale images and it gives better Peak Signal-to-Noise Ratio (PSNR).

International Journal of Soft Computing & Engineering , 2013,
Abstract: With the vast growth of Internet use nowadays, business advertising has enjoyed a more advanced phase. There is a wider selection for media, advertising cost and market range. The challenge is to find which one to focus on. Among the many options, social networking site has turned out to be one of the most promising media today. Keeping this motive Amigos offers completely redesigned advertisement management algorithm which takes advantage of the profile data and hence targets advertisement directly to user according to his interests. Amigos covers most of the essential aspects of social network including editable profiles, messages, groups , events , status updates , uploading photos. Although that is true , the social network does have some unique features of its own like segregation of personal and professional information and displaying the UI accordingly. It would help people willing to join a single networking site and yet be able to control the two fronts of their lives separately. The advertising module looks over the space management of ads and displays them according to user preferences. Not only that, it also gives the advertiser different options to choose from fixed spaces for frequently accessed pages or real time bidding for inner pages .Thus using Social networking the advertising industry can target masses and lead the advertisers to build long term success in the performance advertising industry.

Jashnani Kusum,Baviskar Rutuja
Indian Journal of Pathology and Microbiology , 2010,
Abstract: Background: Laparoscopic surgery is a recent advance in the field of gynecological surgery. There are innumerable reports in literature on its advantages and disadvantages. However, problems faced by the surgical pathologist during grossing and histopathological reporting of these morcellated specimens have never been discussed before. We present our experience and the difficulties faced by a gynecologic pathologist (first author) and try to provide some clues for their solution. Materials and Methods: Sample size was 153 consecutive laparoscopic specimens, which varied from in toto uterus with cervix, fibroid or ovarian cyst to morcellated specimens. 153 non-laparoscopic gynecologic specimens constituted controls; 34.0% were ovarian cystectomies and remaining 66.0% were hysterectomies, myomectomies and salpingectomies, of which 36.6% were morcellated, rest were in toto. Result: Contents were not seen in majority of the ovarian cystectomies. Many more sections were taken in morcellated specimens, as compared to controls, for identification of endometrium, endocervix and ectocervix. Even then, in occasional cases identification was not possible. Congested bits in morcellated specimens interpreted as endometrium on grossing turned out to be parametrial tissue. Ectocervix could be identified as soft tissue bits covered by whitish membrane. Identification of transformation zone of the cervix was not possible in any of the morcellated hysterectomy specimens. Conclusion: The advantage of laparoscopic gynecological surgery to the patient need not prove to be so for surgical pathologist. The present study does not discourage gynecologists from performing laparoscopic surgeries but wishes to highlight the surgical pathologist′s problems and limitations.
A Dynamical Model to Analyze the Influence of Sliding Friction on Motion on a Curve—An Analytical Method  [PDF]

Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.58043
Abstract: To demonstrate the influence of sliding friction of motion on a curve, a circular path is considered for simplicity on which a person slides from the highest point to the lowest point. A slide which represents a quadrant of radius 5 m and a person of mass 60 kg are considered for comparison in this paper. A Differential equation for motion considering the fact that the normal force depends both on the sin component of weight and also on the tangential velocity, is established and is solved using integrating factor method, and the motion is analysed for different surface roughness of the slide and is compared using superimposed graphs, also the limiting value of friction coefficient at which the person just exits the slide is determined. The correction factor for exit velocity with friction as compared with the exit velocity for zero friction is determined. The fraction of energy lost to friction at the exit is evaluated. The Variation of normal force with the position of the person on the slide is plotted for different surface roughness of the slide, and the position on the slide where the normal force or the force experienced by the person is maximum, is determined and hence its maximum value is evaluated for different surface roughness. For simplicity, a point contact between the body and the slide is considered.

Abstract: Nanoparticles are extensively used for various applications in science, engineering and medicine. Synthesis of nanoparticles with high purity is essential to utilize the same in different fields of science and technology. In the present study, liquid chromatography is utilized to purify the nanoparticles. Predominantly, gold nanoparticles were synthesized from gold auric cholide and preserved in phosphate or citrate buffer. A method to purify gold nanoparticles is essential because of the possible interference from gold auric chloride and other impurities in buffer. Herein, a method has been developed using high performance liquid chromatography to purify gold nanoparticles with 100 nm in size from gold auric chloride and residues. UV-Vis spectroscopy was also done to ascertain the purity of the nanoparticles.

Abstract: Background: Mifepristone is potentially a method of inducing labour in late pregnancy by increasing uterine contractility and by increasing the sensitivity of the uterus to the actions of prostaglandins. Present study was done to portrait the beneficial of mifepristone induction of labour. The objective was to study the effect of mifepristone in induction of labour with the outcome of induction of labour (IOL). Methods: 100 patients (term) were included, after their informed consent. Patients were categorized by BISHOP SCORE at the beginning of induction for comparison of BS, mode of delivery, induction delivery interval (IDI). Women undergoing induction with RU486 (200mg PO) were grouped in one and those with placebo control group into another. Statistical analysis of categorical variables was done. Results: Rate of successful IOL or vaginal delivery was 76% in study group and only 36% in control group. After induction with mifepristone for cervical ripening in study group 76% patient who had cervical score <3 on admission had cervical score improved to>8 within 24 hours, whereas in control group 2% female’s cervical score was>8. Among the babies, 44% in the control group required baby unit admission as compared to 36% in the study group. Conclusions: In the present study, the women who were induced with mifepristone 200 mg per orally showed drastic improvement in cervical score within 24-48 hours and decreased the cesarean rate in the study group and amount of dose requirement of augmentation of labour with Misoprostol or Oxytocin, lesser NICU admission and maternal complication.

Abstract: Methane is a reliable and an abundantly available energy source occurring in nature as natural gas, biogas, landfill gas, and so forth. Clean energy generation using methane can be accomplished by using chemical looping combustion. This theoretical study for chemical looping combustion of methane was done to consider some key technology development points to help the process engineer choose the right oxygen carrier and process conditions. Combined maximum product (H2O?+?CO2) generation, weight of the oxygen carrier, net enthalpy of CLC process, byproduct formation, CO2 emission from the air reactor, and net energy obtainable per unit weight (gram) of oxygen carrier in chemical looping combustion can be important parameters for CLC operation. Carbon formed in the fuel reactor was oxidised in the air reactor and that increased the net energy obtainable from the CLC process but resulted in CO2 emission from the air reactor. Use of CaSO4 as oxygen carrier generated maximum energy (?5.3657?kJ, 800°C) per gram of oxygen carrier used in the CLC process and was found to be the best oxygen carrier for methane CLC. Such a model study can be useful to identify the potential oxygen carriers for different fuel CLC systems. 1. Introduction Energy demand and thus energy generation are ever increasing in many parts of the world. Carbon-based fossil fuels are the main source of energy for combustion reactions. However, the major product of energy generation using fossil fuels by combustion is CO2, and growing CO2 pollution has become a matter of serious concern amongst developed as well as developing countries. CO2 is mainly emitted from energy sector that uses coal, oil, and natural gas for combustion to generate energy for different purposes using air as an oxygen source. Although CO2 capture and sequestration is being projected as a potential option to control GHG emissions, CO2 capture technologies in-vogue are beset with several limitations including cost and energy penalty [1, 2]. Hence, these flue gases are directly vented to the atmosphere without CO2 separation and became responsible for environmental impacts of energy generation from fossil fuels, for example, global warming and climate change phenomena [3–5]. In 2010, CO2 emissions have already increased to 389.0?ppm and the burning of fossil fuels is one of the main causes for the same as reported by World Meteorological Organization [6]. This has promoted the development of clean energy technologies as a major research area worldwide. Chemical looping combustion (CLC) is an emerging clean energy technology
