 Abstract

Essential oils have been shown to possess antibacterial, antifungal, antiviral, insecticidal and antioxidant properties.Some oils have been used in treatment of infection in gallbladder. Essential oils are a rich source of biologically active compounds. Therefore, it is reasonable to expect a variety of plant essential oils with specific as well as general antimicrobial activity . The activity of essential oils was evaluated against five bacterial pathogens including E. coli, Salmonella sp, Klebsiella, Streptococcus, Staphylococcus (test bacteria) using disc diffusion method. Microorganisms used in this study were isolated from patients of GB diseases. Test bacteria were characterized on the basis of their biochemical characteristics. Screening of essential oils for antimicrobial activity was performed by disc diffusion method, which is normally used as rapid method to assess antimicrobial activity of essential oils . Our study have analyzed that these essential oils are useful for the preparation of herbal drugs which can be used in the treatment of infective diseases. It can also be concluded that essential oils shows good activity against test bacteria.

 Abstract

Cloud Computing is popular for its characteristics and Essentials, majorly it is used for storage, where the personal storage as services such as drop box and one drive attracting towards the cloud. The designing and analyzing of TasS, that is testing as a service is an automated service, where the research is to be carried out in the domain of testing especially when run in cloud is discussed along with the practical implementation. We majorly focused on different types of testing technologies such as testing major enterprise resource planning and monitoring and testing cloud based applications, As the scope of the application testing in all areas is focused, as it is to be noted that all applications cannot be tested in cloud and all testing techniques are not be appropriate, to be tested for applications running in cloud. The case study is done on different testing methods and methodologies such as security testing, performance testing and software testing. We even focused on the most common security characteristics such as confidentiality, Data Integrity, Availability, Non-Reputation and Authentication. The Genetic algorithmic approach is given for the wide scope and effective testing in cloud. We even concentrated on different testing domains in cloud, carried out acceptable to achieve effectiveness of testing in cloud.

 Abstract

This paper analyzes the characteristics of combination of wavelet transform and second generation Curvelet transform. In the existing system, Wavelet transform of two images (i.e.) the image may be CT image or MRI image is obtained and the curvelt transform is taken for the wavelet transformed image. Finally the two curvelet transformed images are fused. The limitation of this method is loss of curved ends in WT image and loss of sharp ends in the Curvelet transformed image. Wavelet transform takes block base to approach the singularity of C2. So curved ends are missed in this transformation but we can obtain the sharp ends. By using Curvelt transform we can able to recover the curved ends of the image because it takes wedge base to approach the singularity of C2. But we missed the sharp ends in the Curvelet transformed image. But in the proposed system, Wavelet transform as well as Curvelet transform is taken for two CT images. These two transformed images are then fused. The similar technique is applied for MRI image also. So that we can able to recover both the sharp ends and the curved ends when we use these two transformed images. The fused image is more informative than the original image.

 Abstract

Here a distribution power system with pi &pr controller to suppress harmonic resonance is presented. Here, in the distribution power system a parallel connected filter operates as a harmonic conductance, which can reduce the resonance produced harmonically. Normally filter behaves as admittance instead of conductance because of phase lagging concept in Digital Signal Processing (DSP). As a result an unwanted harmonics may get amplified at some different location while starting the filter. Here, PI and PR controllers are used for the suppression of harmonic resonance. To control the currents of a converters which are connected in a grid way the PI controllers are used. The PR controllers compensate the needed harmonics. At harmonic frequencies to assure that the filter used here functions as conductance, the band pass filters are connected in parallel and tuned to the specific value. By the obtained result it is clear that the presented work provides good damping than other control methods.

This paper presents an implementation of sliding mode controller (SMC) together with a fuzzy logic controller for a DSTATCOM (Distribution STATIC COMCOMPENSATOR) for improving current induced power quality issues and voltage regulation of three-phase self-excited induction generator (SEIG). The fuzzy controller is the most reasonable for the human basic leadership component, giving the operation of an electronic framework with choices of specialists. The utilization of SMC for directing the DC link voltage of DSTATCOM offers different preferences, for example, reduction in number of sensors for assessing reference currents and the steady DC link voltage during transient conditions. The utilization of fuzzy controller for terminal voltage control gives the error free voltage direction in consistent state conditions. The voltage control highlight of DSTATCOM offers the upsides of single point voltage operation at the generator terminals with the reactive power compensation which maintains a strategic distance from the saturation in the generator. The SMC calculation is effectively executed on a DSTATCOM utilized with a three-phase SEIG sustaining single phase or three phase loads. The execution of the proposed control calculation is discovered attractive for voltage direction and relief of energy quality issues like reactive power compensation, harmonics elimination, and load balancing under nonlinear/linear loads. Compare the results for SMC with PI controller and fuzzy controller.

 Abstract

This paper proposes a novel converter topology for HVDC applications; this is known as the Alternate Arm Converter (AAC). The AAC is a half and half topology between the two-level converter and the secluded multilevel converter. Since AAC having H-connect cells as chief switches in each arm of converter. Because of stacking of H-connect cells in AAC it can ready to create a multilevel air conditioning voltage. AAC having capacity to create higher air conditioning voltage than the dc terminal voltage, this permits the AAC to work at an ideal point, called the "sweet spot". At the point when blame happened at dc-side the AAC can directs current in stage reactor through a STATCOM mode operation to help the air conditioner matrix network. The current and voltage qualities at dc and air conditioning side of network are reproduced through MATLAB/SIMULINK.
