 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.

 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.

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.

Abstract : Fat soluble vitamins are those which are dissolved in fat. Among the fat soluble vitamins, vitamin D is one of them. The main source of vitamin D is ultraviolet rays sunlight. Less amount of vitamin D is synthesized among dark skinned people than fair skinned people because the pigments within dark skin inhibit the entrance of ultraviolet radiation. Besides sunlight, humans can take vitamin D from diet. Vitamin D content foods are very few in nature. Some sea foods contain high amount of vitamin D3 like sardines, salmon and mackerel. . Some foods are fortified with vitamin D but the number of foods are very few. Some vitamin D fortified foods are cereals, some bread, milk and orange juice. The active form of vitamin D is 1,25-dyhydroxyvitamin D3 is known as to control calcium and phosphorus metabolism that is needed for healthy bone formation. Vitamin D has a another special role rather that formulating skeletal system. It act as a immune-modulator. It targets immune cells of various types like monocytes, macrophages, dendritic cells, as well as T and B lymphocytes, it control both innate and adaptive immunity. Now a days one of the major public health problem in India is Tuberculosis, a infectious bacterial disease named Mycobacterium Tuberculosis or MTB. Approximately 8.6 million TB cases were found globally and approximately 2 million TB cases were occurred in India. Underweight (BMI<18.5) means the weight less than normal weight. Underweight was observed in low economical group specially. Underweight is mainly seen in developing countries. A synergistic interaction was found between underweight and low level of vitamin D. It has been identified that maximum number of TB patients has very low body weight(underweight) Vitamin D is mainly beneficial for chronic infection like tuberculosis(TB). Deficiency of vitamin D occur when the people do not get enough ultraviolet B ray that come from sun light and another reason is that when the people do not get sufficient amount of vitamin D from the dietary sources. Most of the foods has very small amounts of vitamin D. Certain sea fishes are known as good sources of Vitamin D. Marine fishes should be incorporated in the diet. Fresh water fishes has moderate amount of vitamin D in their liver. Fortification of oil and wheat-flour with vitamin D may fill the gap of vitamin D deficiency.

 Abstract

The objective of the study was to formulate controlled release matrix tablets of losartan Potassium by using a combination of hydrophilic synthetic polymer like poly (ethylene oxides) and natural gums like xanthan gum, karaya gum and guar gum. A combination of synthetic hydrophobic polymers like methacrylates with synthetic hydrophilic polymer like poly (ethylene oxide) was also used in the preparation of matrix tablets and evaluated for their influence on controlled drug release. The matrix tablets were prepared by direct compression process and evaluated for hardness, weight variation, friability, swelling index and for in-vitro release of the drug. Preliminary evaluations showed that matrix tablets containing xanthan gum, guar gum and sodium alginate alone or in combination could not efficiently retard the drug release for prolonged period of time. The tablets containing combination of natural polymers and poly (ethylene oxides) and also methacrylates and poly (ethylene oxides) exhibited controlled release for a prolonged period of time. All the physical characteristics evaluated for the tablets were found to be within the acceptable limits.

 Abstract

Nearest neighbor search in multimedia databases needs more support from similarity search in query processing. Range search and nearest neighbor search depends mostly on the geometric properties of the objects satisfying both spatial predicate and a predicate on their associated texts. We do have many mobile applications that can locate desired objects by conventional spatial queries. Current best solution for the nearest neighbor search are IR2 trees which have many performance bottlenecks and deficiencies. So, a novel method is introduced in this paper in order to increase the efficiency of the search called as Spatial Inverter Index. This new SI index method enhances the conventional inverted index scheme to cope up with high multidimensional data [7] and along with algorithms that?s compatible with the real time keyword search [2].
