Comparison of Dynamic Stability Response of A SMIB with PI and Fuzzy Controlled DPFC
Consumer utilities are non âlinear in nature. This injects increased flow of current and reduced voltage with distortions which cause adverse effect on the stability of consumer utilities. To overcome this problem we are using a modern Flexible Alternating Current Transmission System controller i.e. distributed power flow controller (DPFC). This controller is similar to UPFC, which can be installed in a transmission line between the two electrical areas. In DPFC, instead of the common Dc link capacitor three single phase converters are used. In this paper we are concentrating on system stability (oscillation damping). For analyzing the stability of a single machine infinite bus system (SMIB) we have used PI controlled Distributed Power Flow Controller (DPFC) and Fuzzy controlled DPFC. All these models are simulated using MATLAB/SIMULINK. Simulation results shows Fuzzy controlled DPFC are better than PI controlled DPFC. The significance of the results are better stability and constant power supply
UV-C treatment of soymilk in coiled tube UV reactors for inactivation of Escherichia coli W1485 and Bacillus cereus endospores
Coiled tube UV reactors were used to investigate the influence of tube diameter (1.6 mmID, and 3.2 mmID) and Reynolds number (Re) to inactivate Escherichia coli W1485 and Bacillus cereus spores in raw soymilk (RSM). Four levels of Re (343, 686, 1029 and 1372) were tested in RSM inoculated separately with each bacterium and treated in the UV reactors at a constant residence time of 11.3 s with UV-C dose of 11.187 mJ/ cm2 at 253.7 nm. Inactivation efficiency of both microorganisms increased with Re. Maximumreductions of 5.6 log10 CFU/ml of E. coli and 3.29 log10 CFU/ml of B. cereus spores were achieved in the 1.6 mm ID UV reactor. Inactivation efficiency was higher in the 1.6 mm ID UV reactor than the 3.2 mm ID UV reactor for both the organisms. Effect of UV-C light on lipid oxidation of untreated RSM, measured as malondialdehyde and other reactive substances (MORS) content, was much higher (95 nmol/ml) than the UV-treated (58 nmol/ml) and thermally pasteurized (55 nmol/ml) RSM during the storage period of 7 days. The UV-C treatment can be effectively used for reducing E. coli cells and B. cereus spores in soymilk without compromising its quality

Impact of UV-C processing of raw cow milk treated in a continuous flow coiled tube ultraviolet reactor
Raw cow milk (RCM) was treated in a continuous flow coiled tube ultraviolet reactor at the Reynolds number (Re) of 713 for a residence time of 17 s with cumulative UV-C dose of 16.822 mJ/cm2. SPC in RCM was reduced by 2.3logs at these conditions. Sensory analysis of milk samples was conducted using triangle test. UV-C treated RCM and untreated RCM was compared with the fresh RCM (control) using triangle test method of olfactory sensory analysis right after the UV treatment and during storage periods (1, 3, 7 d) at 4â. There were no significant differences among the odor of UV-light-treated, untreated, and control, right after the UV treatment. Perceivable change in the odor of UV-treated and untreated RCM compared to the fresh RCM was observed on the 3rd and 7th days after treatment. There was no significant difference between the malondialdehyde and other reactive substances (MORS) content in untreated and fresh milk right after the treatment and during storage. Lipid oxidation products content of UV-treated RCM was significantly higher than that of the fresh or untreated RCM.Keywords: raw cow milk, ultraviolet processing, UV-C treatment, sensory test, lipid oxidation substance
Applying Three Port Converter with Dual Battery Storage System for Hybrid Power Generation
640-646The proposed research work used three power sources, namely wind energy, solar energy and grid. Wind and solar constitute the primary energy sources while the grid acted as the secondary one; added to that, we have the battery storage system. The priority between the two forms of energy in the primary source is determined by their availability. The solar irradiance is available during daytime, whereas during cloudy and night times, energy extraction is impossible; besides that wind energy is also not reliable. Thus the central level controller (CLC) is used, which serves as a deciding authority for the selection of primary source. When none of the energies in the primary sources are available the grid supplies the required power to the load. When there is a surplus energy from primary sources, it is stored in a battery or exported to the grid. In addition DBSS is also introduced for effective utilization of battery storage system. The proposed model is connected with micro grid to provide utilization path for surplus power. The overall design and simulation is performed by using MATLAB/SIMULINK
THIRTY FIVE YEARS OF OPERATIONAL RESEARCH PROJECT FOR DRYLAND AGRICULTURE : ACHIEVEMENTS AND IMPACTS (1976 to 2012)
Not AvailableAgriculture is the backbone of Indian economy and rainfed agro-ecosystem occupies an
important place in Indian agriculture, covering 68 per cent of the cultivated area (96 m.ha)
supporting 40 per cent human, 60 per cent livestock population and producing 44 per cent of the
food requirements thus playing a pivotal role in Indiaâs food security.
Five out of ten Agro-Climatic Zones in Karnataka were classified as dry zones covering
63 per cent of the total geographical area and 71 per cent of the net sown area, with substantial
contribution to agricultural production from dry lands. About 57 per cent of food grain production
in Karnataka comes from rainfed areas while, 97 per cent of total pulses and 80 per cent oilseeds
were produced in dry land areas.
Research on dryland agriculture in the red soil regions of Karnataka was started in 1970
with the establishment of All India Coordinated Research Project for Dryland Agriculture

New Symmetries in Crystals and Handed Structures
For over a century, the structure of materials has been described by a
combination of rotations, rotation-inversions and translational symmetries. By
recognizing the reversal of static structural rotations between clockwise and
counterclockwise directions as a distinct symmetry operation, here we show that
there are many more structural symmetries than are currently recognized in
right- or left-handed handed helices, spirals, and in antidistorted structures
composed equally of rotations of both handedness. For example, though a helix
or spiral cannot possess conventional mirror or inversion symmetries, they can
possess them in combination with the rotation reversal symmetry. Similarly, we
show that many antidistorted perovskites possess twice the number of symmetry
elements as conventionally identified. These new symmetries predict new forms
for "roto" properties that relate to static rotations, such as rotoelectricity,
piezorotation, and rotomagnetism. They also enable symmetry-based search for
new phenomena, such as multiferroicity involving a coupling of spins, electric
polarization and static rotations. This work is relevant to structure-property
relationships in all material structures with static rotations such as
minerals, polymers, proteins, and engineered structures.Comment: 15 Pages, 4 figures, 3 Tables; Fig. 2b has error
Alleviation of Multinutrient Deficiency for Productivity Enhancement of Rain-Fed Soybean and Finger Millet in the Semi-arid Region of India
Soil nutrient contents were determined in 802 surface soil samples (0â15 cm deep) collected from farmers' fields that support extensive cultivation of soybean (Glycine max L.) and finger millet (Eleusine coracana G.), spread across three districts, in the semi-arid regions of Karnataka, India. Following soil analysis, on-farm crop trials were conducted during 2005â2007 to study the crop response to the soil application of nitrogen (N), phosphorus (P), sulfur (S), boron (B), and zinc (Zn) fertilizers. Analyses of soil samples revealed that 4â83% fields were deficient in N, 34â65% in P, 83â93% in extractable S, 53â96% in B, and 34â88% of farmers' fields were deficient in Zn. On-farm trials conducted during the three rainy seasons (2005, 2006, and 2007) significantly (P †0.05) enhanced crop productivity indices such as yields of grain, stover, and total biomass in soybean and finger millet crops. Integrated management of deficient nutrients in finger millet and soybean crops significantly enhanced the grain and straw uptake of N, P, K, S, and Zn
