 Abstract

A grid tied inverter mainly required voltage and current measurement to reactive power and active power or else inverter output current. Voltage sensors are reliable information on the phase angle using these additional components increase the cost of production and system complexity. In this paper, sensorless voltage control for a grid tied inverter using disturbance observer with net meter is presented. The grid voltage is estimated by disturbance observer in the stationary frame reference using the reference signal and current measurement. The disturbance observers estimate the grid voltage with reasonable accuracy with Presence variable such as the unbalanced condition and harmonics distortion. The result waveforms shows that a phase leg depending on the estimation bandwidth.to outcome this limitation, a phase lead compensation is newly introduced.by using these new concept phase angle of a grid voltage can be completely restored. If the phase angle of grid is initially unknown. New technology based Proposed Sensorless voltage control experiments using 2KVA prototype inverter.

Every Software development project follows the certain model such water fall model, spiral model or popularly known as Software Development Life Cycle, which breaks down the complex software project into many small chunks which is easy to handle and implement. Similarly Exploratory Data Analysis also requires to be done in phase wise manner. This paper presents the complete overview of exploratory data analysis life cycle.

 Abstract

The present investigation was planned to quantify plasma protein analytes in Indian major carps from lakes of Ajmer city, Rajasthan. Experimental material incorporated Indian major carps i.e. Rohu (Labeo rohita) and Catla (Catla catla). A total of 240 fish were incorporated in the study. Out of this, 120 fish type were Labeo rohita (Lr) and 120 fish type were Catla (Cc). To evaluate the impact of pesticides and their possible damage to aquatic life, water samples and fish were collected from two reservoirs (lakes) of Ajmer city, Rajasthan namely Ana Sagar lake, Ajmer, Rajasthan and Foy Sagar lake, Ajmer, Rajasthan. At each collection site, Catla catla fish revealed lower plasma biochemical contents than Labeo rohita fish. This exhibited that Catla catla fish built up greater degree of stress than Labeo rohita fish. In both the category of fish, females revealed lower contents of plasma biochemical than males. This pointed up that females of both the type of fish had developed higher scale of stress. Furthermore, it was found that low-weight male and female fish had larger amount of stress than high-weight male and female fish. Plasma biochemical were significantly (p?0.05) lower in low-weight fish than high-weight fish.

 Abstract

Current methods of image protection based on chaos encryption can only provide security in Human visual system (HVS) level, however they can not provide usage control when the image is opened, printed or exported. To solve this problem, we proposed a novel image digital rights management scheme for Confidential image data security based on encryption and watermark (CIDSEW) with high-level security, usage control and traceability,in which we employed full content image encryption for confidentiality of the image to be protected, and we firstly proposed strict and detailed Usage control (UC) scheme for Confidential image data (CIData) usage password-based authentication, opening times, printing and exporting control. And when the CIData need to delivery or export to other users or domain, we proposed the secure export and misused tracing and detect approach, in which before the ciphered CIData is exported, we decrypted the CIData in a plain mode, and simultaneously we embedded user-identity-related and hardware-related information as robust watermark for traceability and responsibility confirmation. To enhance the security, in this system the standard encryption method known as Advanced Encryption Security (AES), image split and random pixel embedding techniques are integrated before the data transmitted through the network. After that the stego image is splitted into fragments on the basis of various intensity of RGB color component of pixel. Then the splitted parts are encrypted and transmitted to the receiver.

 Abstract

The genusFicus (Family-Moraceae) is commonly known for its religious status in Indiabut its medicinal values are familiar throughout the world. The medicinal aspects of Ficus plant are well known in ayurveda, homeopathic and other medicinal system. Since, every part of Ficus tree such as roots, stem, bark, latexand leavespossesses aesthetic propertiesand the specific phytochemical constituents including lanosterol, sigmastrol, sitosterol, kaempferol, quercetin, myricetin, bergapten, bergaptol, leucoanthocyanin, lupeol, psoralen, friedelin, rutin, taraxosterol, saponins, monoterpenes and other pharmaceutical product used to cure skin diseses, cardiovascular disease, renal disease, joint pains, ear problems, gastro-intestinal disease, piles, menorrhagia, healing and curative wounds,boils and mumps,constipation,respiratory problems, fibrositis, sprains, hepatic and gastovascular disorders considerably from last few decades.Medicinal system achieved a great progress in exploration on medicinal properties of Ficus species. Fruits of some Ficus species is edible from ancient civilization and also leveraging intribal communities. In this review, the pharmacological and medicinal value ofgenus Ficushave been discussed to provide collective information on multipurpose use of sacred plant as to promote the cultivation at commercial level.

 Abstract

Lung cancer also known as carcinoma is one of the common cause of death among people throughout the world. Early detection of lung cancer can increase the chance of survival among people. Medical Imaging plays an important role in the early detection and treatment of cancer. Computer Aided Diagnosis (CAD) system allows detection of lung cancer through analysis of chest CT scan images. This work is basically focusing on Segmentation and nodule extraction, in which nodule attributes like image intensity, shape and size have to be taken into consideration. The objective of this study is identifying all nodules from the chest CT lung images and classifying these nodules into Malignant and Benign nodules, using Image processing techniques.

 Abstract

Nowadays in 21th century, large number of people have smart phones in their hand, by which their life is simplified to a great extent. They provided easy, fast, secure and hassle free solutions to the problems faced by people. They can do anything like sending messages, photos and videos (using apps like whatsapp), sending money (using apps like paytm) or checking the bank balance. Butthere are some areas where still work is done manually, which can be made simpler by using mobile apps In this research paper, our topic is about E-mechanic. The reason for keeping the name as E-mechanic provides online mechanics for any vehicle, which can be improvised and made more efficient by using mobile application.

 Abstract

A 30 year old male IT worker walked in with a complaints of headache and right side neck stiffness which was bothering him for a couple of weeks. He could not recall any injury or event which triggered the problem. The severity of pain increased when doing his work as an IT profession. He never complained about sleep disturbance due to this problem. He did find some relief in hot packs and application of analgesics, but much to his dismay the relief was short lived. He was been diagnosed as cervicogenic headache by performing flexion rotation test. Conservative management along with SNAG was given to the patient to get immediate relief from headache and stiffness.
