HIGH EFFICIENCY PHOTOVOLTAIC POWER CONTROLLER USING MPPT AND BUCK BOOST CONVERTER

The maximum power point tracking (MPPT) is used in photovoltaic system to maximize the photovoltaic array output power , irrespective of temperature , IR radiation, conditions and electrical characteristics of the load. A new MPPT system is developed consisting of DC to DC converter, which is controlled by microcontroller based unit. There are two charging stages for the proposed PV charger. At the beginning of charging process, a continuous MPPT charging scheme is adopted. When the State of Charge (SOC) of battery reaches the given condition. a pulse current charging scheme with adaptive rest period applied to obtain an average charging current with an exponential profile. During the charging period MPPT function is retained to achieve high charging efficiency. Over charging of the battery can be avoided using the pulse charging scheme with adaptive rest period. The main difference between the method used in the MPPT system and other techniques used in the past is that the PV array output power is used to directly control the DC to DC converter, thus reducing the complexity of the system . In addition, we attempt to design the MPPT by using the algorithm of a selected MPPT method which is “Perturb and Observe “and implement it by using a DC– DC Converter. We have found various types of DC-DC converters . Among them we have selected the most suitable converter which is “BUCK-BOOST” converter , for our desing.PV generation system generally use a microcontroller based charge controller connected to a battery and the load. A charge controller is used to maintain proper charging voltage on the batteries. As the input voltage from the solar array, the charge controller regulates the charge to the batteries preventing any overcharging. So a good, solid and reliable PV charge controller is a key component of any PV battery charging system to achieve systems maximum efficiency. Whereas microcontroller based designs are able to provide more intelligent control and thus increases the efficiency of the system.
ANTI-SPOOFING AND AUTHENTICATION OF A FACE IMAGE USING DIFFUSION SPEED MODEL

--------------------------------------------------------------------- Abstract - Face recognition is a broadly applicable biometric approach. Face recognition technology is developed rapidly in recent years. It is more direct, user friendly and convenient compared to other methods. But most of these face recognition systems are vulnerable to spoof attacks made by fake faces or non-real faces. It is very easy to spoof face recognition systems by using facial pictures such as portrait photographs or videos. A secure system needs Liveness detection in order to protect against such spoofing methods. This paper proposed a new method to make sure that the data is being provided by a live user and not from artificial sources. In this method, difference in surface properties between live and fake faces can be efficiently estimated by using a diffusion speed model. We computing the diffusion speed by extracting anti-spoofing features based on the local patterns of diffusion speeds called Local Speed Patterns. These features are subsequently input into a linear SVM classifier to determine the liveness of the given face image. And finally check the authentication of given face image by utilizing an eigenface algorithm. Accuracy results on data sets show that the proposed method is an efficient face liveness detection system.

Maximum Power Point Tracking of PV Array at Partially Shaded Conditions using Matlab

A PV array is a nonlinear power source. The output power induced in the photovoltaic modules depend on solar radiation and temperature of the solar cells. The selection of converter is important for MPPT operation. A boost converter (step-up converter) is a Dc to Dc power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter). The MPPT algorithm represents optimal load for PV array, producing opportune voltage for the load. Perturbation and Observation (P&O) method has a simple feedback structure and fewer measured parameters. It operates by periodically perturbing (i.e. incrementing or decreasing) the array terminal voltage and comparing the PV output power with that of the previous perturbation cycle. Keywords— PV Array; MPPT, Boost Converter
Synthesis, Biological Evaluation and Molecular Modeling Studies of 5-[4-(substituted) benzylidene or benzyl] thiazolidine-2,4-dione with Oral Antihyperglycemic Activity

A new series of 5-[4-(substituted) benzylidene or benzyl] thiazolidine-2,4-dione have been synthesized using economical synthetic routes. The synthesized compounds 4a-4c, 7a-7c and 14a-14c were evaluated for their oral antihyperglycemic activity by fructose induced hyperglycemia in Wistar rats. From the results, compounds 7c and 14b have appreciable blood glucose-lowering effect compared to that of the reference drug, pioglitazone. Hypoglycemic activity of all compounds was compared with the results of their docking after removal of the co-crystallized ligand present in the 2PRG structure. Out of these compounds, compound 14b shows better interaction with amino acid residues of PPAR-γ and also shows better oral antihyperglycemic activity in this series.

PABKE: Provable Attribute-based Keyword explore over Outsourced Encrypted Data

:- Cloud Computing has changed the phenomena of IT industry completely. It allows access to highly scalable, inexpensive, on demand computing resources that can execute the code and store data that are provided. But adoption and approach to cloud computing applies only if the security is ensured. Cloud computing is lacking in security, confidentiality and visibility. Secure the cloud means to secure the storage. Security is achieved by the encryption. There are various encryption standards to ensure the cloud security. Attribute-based encryption (ABE) is public key encryption technique that allows users to encrypt and decrypt messages based on user attributes. In a typical implementation, the size of the cipher text is proportional to the number of attributes associated with it and the decryption time is proportional to the number of attributes used during decryption. To reduce the decryption time in cloud outsourced decryption technique is used. By providing a transformation key to the cloud ABE cipher text is converted into simple cipher text and it only incurs a small computational overhead for the user to recover the plaintext from the transformed ciphertext. To ensure that transformation performed by cloud server is correct and the data is not modified by the untrusted servers proposed system is introduced. This provides secured and Verifiable Outsourced decryption.

Intraday VaR using Component GARCH-EVT Approach: An Empirical Study in Select Stock Markets

The purpose of this study is to estimate intraday VaR using an appropriate method based on defining characteristics of high frequency stock price indices taken from select markets of the world. The stylized properties observed in the data set used in the study are that the return series exhibit skewed and leptokurtic distributions, volatility clustering, periodicity of volatility and long memory process in volatility, all of which together suggest the usage of Component GARCHEVT combined approach on periodicity adjusted return series to forecast accurate intraday VaR. Hence we have estimated intraday VaR using Component GARCH-EVT combined approach with different innovation distributions such as normal, student t and skewed student t and examined its relative accuracy for VaR forecasting with the benchmark GARCH-EVT model. As expected, the Component GARCH-EVT models in general perform better than GARCH-EVT models in estimating and forecasting VaR. Within the Component GARCH-EVT models, although no model with a particular innovation consistently dominates others, the model with skewed student t innovations relatively perform better than the models with other innovations. The study is useful for market participants (such as intraday traders and market makers) involved in frequent intraday trading in such equity markets. _____________________________________________________________________
Evaluation of Dengue and Malaria co-infection in Rohilkhand Region of Northern India

Introduction: Both dengue and malaria are mosquito borne diseases, which are associated with high morbidity and mortality thus posing a worldwide public health problem. Both infections are endemic in tropical regions, leading to coinfections. Concurrent infections of malaria and dengue are when both the diseases occur simultaneously in an individual. Because of the similar clinical presentation between these two infections, the diagnosis of malaria and dengue co-infections might be either misdiagnosed or misinterpreted as monoinfections. This study was aimed to evaluate the dengue and malaria co-infection from this region. Material and methods: A total number of 994 patients suffering from acute febrile illness were included in the study and screened for malaria and dengue infection. Blood sample from each febrile patient was collected in plain and EDTA vacutainer and were sent to the laboratory. The screening for malarial parasite was done by both rapid immunochromatographic test and microscopic examination of peripheral blood films (both thin and thick). Dengue screening was done by rapid immunochromatographic test as well as by dengue MAC ELISA. Results: 295 (29.67%) were found to be infected with dengue infection. Malaria parasite was found in 685 (68.91%) patients. Among them 430 (62.77%) cases were infected with Plasmodium vivax while 255 (37.22%) of cases were due to Plasmodium falciparum infection. Dengue and malaria coinfection was present in 30 (3.40%) patients with Plasmodium falciparum (53.33%) in most of the cases. Conclusion: The finding of this study indicates that denguemalaria co-infection is not uncommon. Both the infections presents clinically indistinguishable clinical features, early diagnosis of concurrent infection can be lifesaving.
Effect of Blend Herbal Supplement on Haematology and Serum Biochemistry in Commercial Layer Chicken

Many herbal supplements are tested for theirs efficacy in poultry to replace the antibiotic growth promoter. Hence this study was carried out to find the effect of a blend herbal preparation (Ocimum sanctum, Zingiber officinale, Allium sativum, Trigonella foenum graceum and Curcuma longa) on the vital parameters in layers. An experimental trial for three weeks was carried out on 80 layers aged 11 weeks. Birds were randomly divided to 4 groups with 2 replicate for each group and supplemented by herbal preparation @ 0.1 percent, 0.25 percent and 0.5 percent in feed. The results indicated a significant increase in the red blood cells count, white blood cell count, total protein, albumin, globulin, calcium, phosphorus and reduction in the enzyme aspartate aminotransferase and alkaline phosphatase with alanine aminotransferase in the normal range. The significant increase in the vital parameters, decrease in hepatic enzymes inside the clinically healthy condition denote that the birds were in good health. Birds increased nutrient utilization, improved oxygen carrying capacity and caused active immune system. The better absorption of minerals like calcium and phosphorus signifies the role of herbs in enhancing digestion performance. Oral feeding caused a normal activity of hepatic enzymes which can prove safety and hepatoprotective nature of these herbs. Therefore, it can be concluded that supplementation of these herbs in the layer feed could be important in prevention of diseases in birds. However further studies are recommended to indicate the toxic levels of these herbs and optimize the beneficial dosage in diet of layer birds.
Closed Loop Control of an Interleaved Buck Converter with High Step-Down Conversion Ratio and Low Switch Voltage Stress

Interleaving can be thought of as a method of paralleling converters but it has got additional benefits to offer in addition to those obtained from conventional approaches of paralleling converters. Interleaved converters due to its simple structure and low control complexity are widely used in applications where non-isolation and high output current with low ripples are required. They have got certain drawbacks such as high cost and high switching losses and require high voltage rated devices. These drawbacks can be rectified by means of a new interleaved DC-DC converter in which two input capacitors are series-charged by the input voltage and parallel discharged for providing a much higher step-down conversion ratio. This paper employs capacitive voltage division principle for increasing the stepdown conversion ratio and reducing voltage stresses of active switches. Thus lower voltage rating switches can be used to reduce switching losses and the overall efficiency is improved. Moreover, due to the charge balance of the blocking capacitor, the converter features automatic uniform current sharing characteristic of the interleaved phases without adding extra circuitry or complex control methods. The closed loop control of the paper is carried out using MATLAB R2012a environment and results are obtained. The closed loop control is given using a PI controller. Finally, a prototype circuit is implemented with 110 V input voltage and 5.5 V output voltage.
Corporate Multinational Flexibility Option and Bankruptcy Resolution

This study is to examine the effects of a firm’s multinational flexibility option on the outcomes of Chapter 11 and durations in the process. For a sample of 403 U.S. companies that filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, we find that multinational enterprises (MNEs) are more likely to emerge from Chapter 11 than domestic enterprises (DEs). Further examination finds that foreign sales ratio is not a significant predictor of successful emergence from Chapter 11, but foreign asset ratio and the number of foreign countries with a revenue-generating subsidiary improve the likelihood of emergence from Chapter 11, suggesting the advantages of multinational network such as operating flexibility, tax savings, and financing advantage.
Isolation and characterization of monocrotophos degrading activity of soil fungal isolate Aspergillus Niger MCP1 (ITCC7782.10)

Monocrotophos (MCP) is both a systemic and control pesticide useful for the protection of various cash crops. The use of pesticide degrading microbial system for the removal of pesticide residue and other products from contaminated systems requires an understanding of the growth requirements of degrading organisms. Monocrotophos (MCP) degrading fungal strain was isolated from soil by enrichment culture. The fungal strain was identified by colony morphology, staining and 18S rDNA analysis as Aspergillus niger (MCP1) (ITCC 7782.10) GenBank accession no JQ660373. Monocrotophos degrading ability of the MCP 1 was characterized as assessment of two parameters i.e growth kinetics of fungal strains in the presence of monocrotophos by dry mass estimation method and degradation kinetics of monocrotophos by spectrophotometric method of estimation at 254nm. Growth kinetics revealed that monocrotophos had induced the growth of MCP 1 to approximately 2 folds. Culture conditions for the growth of MCP 1 were optimized by growing it under different physical and chemical parameters. Optimum conditions for growth were found to be pH-8, Temperature 25-30°C and monocrotophos concentration 150 mg L. Aspergillus niger is capable of degrading 90% monocrotophos under optimized conditions in 10 days. Degradation kinetics of monocrotophos followed straight line equation and half life was thus calculated. Constant of degradation Kdeg was 0.009212 and the half life of monocrotophos was 75.87 hrs. In our study it is the first report showing the potential of Aspergillus niger as a potential degrader of monocrotophos and can be used as a candidate for removal of monocrotophos from agricultural sites.
Evaluation of blood and ascitic fluid oxidative stress in patients with liver cirrhosis

Objective: Liver cirrhosis is the result of chronic inflammation of liver tissue which results for different reasons. One of the useful evaluation indexes for determining the reduction of liver biosynthesis capacity is checking the amount of oxidative stress in the liver cirrhosis patients which changes unnaturally in chronic liver diseases. Therefore, the main goal of this study is to check the amount of oxidative stress in blood and ascites fluid in liver cirrhosis patients. Methods: This is a cross sectional research study in which the target population is liver cirrhosis patients with infectious or non-infectious ascites fluid. The participants are 120 people which are investigated in four different groups. Two samples of blood are taken from all the people and a sample of ascites is taken from cirrhosis patients. The activity of superoxide dismutase and glutathione peroxidase is measured in the samples of blood and ascites fluid. Results: In the above mentioned groups, the activity of superoxide dismutase and glutathione peroxidase in the red blood cells and ascites fluid shows a significant decrease. Conclusion: In the liver cirrhosis patients, the amount of oxidative stress has shown a significant increase. We can use this increase for monitoring the development of disease and also it shows serious damage to liver.
Improved Method of In vitro Dendritic Cells Expansion for Immunotherapy

Developing efficient human dendritic cell-based immunotherapeutic vaccines is one of primary goals of cancer immunotherapy. This is hurdled by necessity to obtain extensive amounts of patient’s dendritic cells, which consist a relatively small population in peripheral blood. This requirement entails the need to take large volume of patient’s blood, which may be a limiting factor, since patient’s condition is already undermined by developing tumor. In this paper we present an optimized method for obtaining large amounts of functional dendritic cells derived from proliferating monocytes to minimize necessary volume of blood taken from the patient. We have confirmed that overexpression of c-Myc and BMI1 genes leads to monocyte proliferation and optimized the method of transgene delivery to monocytes by novel bicistronic lentivirus vector containing sequences of both genes.
