    The article describes an algorithm for predicting the future signals with the aid of past signal samples. In the real signal processing environment, the amplitude and unsystematic in phase signal are lead to more complex to estimation the signal, thereby, customer service is enhanced by forecast. The forecast of financial marketplace are usually done by means of Elliot wave theory. In this article possibility and applicability survey of the EW Theory is proposed in the paper towards the power of the signal forecast. In nature, the EW theory has free declining environment, and also uncomfortable based on the customer and base station and height of the antenna. The proposed algorithm has tested in real life conditions, considering both, the pedestrian persons and the people travelling at 60 Km/Hr. Consequently, the predicted result incorporates the practical signal strength based on increasing distribution utility, signal to intervention noise ratio (SNR) and instability at their subsequent time. The end result of the algorithm shows 68% of successful prediction

    Abstract: A carbonaceous adsorbent prepared from an indigenous waste by acid treatment was tested for its efficiency in removing Rhodamine B (RDB). The parameters studied include agitation time, initial dye concentration, carbon dose, pH and temperature. The adsorption followed first order reaction equation and the rate is mainly controlled by intra-particle diffusion. Freundlich and Langmuir isotherm models were applied to the equilibrium data. The adsorption capacity (Q m ) obtained from the Langmuir isotherm plots were 51.546, 47.236, 44.072 and 41.841 mg/g respectively at an initial pH of 7.0 at 30, 40, 50 and 60 0 C. The temperature variation study showed that the Rhodamine B adsorption is endothermic and spontaneous with increased randomness at the solid solution interface. Significant effect on adsorption was observed on varying the pH of the Rhodamine B solutions. Almost 90% removal of Rhodamine B was observed at 60 0 C. The Langmuir and Freundlich isotherms obtained, positive H 0 value, pH dependent results and desorption of dye in mineral acid suggest that the adsorption of Rhodamine B on PSC involves physisorption mechanism

    38-45A carbonaceous adsorbent (TPC) prepared from Thespusia populinia bark by acid treatment was tested for its efficiency in removing Rhodamine B (RDB). The parameters studied include agitation time, initial dye concentration, carbon dose, pH and temperature. The adsorption followed first order reaction equation and the rate is mainly controlled by intra-particle diffusion. Freundlich and Langmuir isotherm models were applied to the equilibrium data. The adsorption capacity (Qm) obtained from the Langmuir isotherm plots were 60.836, 64.239, 68.695 and 77.178 mg/g respectively at an initial pH of 7.0 at 30, 40, 50 and 60ºC. The temperature variation study showed that the RDB adsorption is endothermic and spontaneous with increased randomness at the solid solution interface. Significant effect on adsorption was observed on varying the pH of the RDB solutions. Almost 79% removal of RDB was observed at 60ºC. The Langmuir and Freundlich isotherms obtained, positive ΔHº value, pH dependent results and desorption of dye in mineral acid suggest that the adsorption of RDB on TPC involves physisorption mechanism

    Experimental studies of propeller induced flow over typical micro air vehicle - AIAA 2013-0060

    Get PDF
    An experimental study has been carried out to explore the effect of propeller induced slipstream on the flow field of a fixed wing micro air vehicle (MAV). Tests were conducted at freestream velocity of 10m/s, corresponding to Reynolds number based on root chord of about 160000. Flow pattern on the surface of MAV planform with propeller-on and off condition was captured using oil flow visualization at four angles of incidence. Mean flow field on the MAV planform at four chordwise planes with propeller-on and off condition were measured using stereo PIV technique at angle of incidence of 24°. Little difference has been seen on the oil flow pattern at 10° and 15° angle of incidence between propeller-off and on condition. Small asymmetry in the flow topology was observe at 20° angle of incidence. Significant difference in flow field was observed at 24° between propeller-on and off condition. The induced slipstream from the propeller makes the flow well attached over the wing planform

    Toxic activity of mercury chloride was tested in vivo on fresh water fish Catla catla. Acute toxicity testswere conducted to measure the impact of toxicity on the fishes within a short period at the variousconcentrations of HgCl2 (0.1, 0.5, 1, 1.5, 2, 2.5 and 3mg/L). The protein and carbohydrate were estimatedusing Anthrone by standard methods and enzymes such as Na+-K+ , Mg2+ and Ca2+ adenoxidetriphosphatases were determined caloriemetrically. Depletion of protein was observed at all exposureperiods. The biochemical estimation values of carbohydrates in muscle, intestine and brain showedsignificant values with P<0.05. The activity of Mg2+ adenoxide triphosphatases in muscle, intestine andbrain was studied and the maximum depletion was observed at 96h, 72h and 72h, respectively. Regardingactivity of Ca2+ adenoxide triphosphatases in muscle, the maximum depletion of this enzyme activity inmuscle was observed at all exposure periods, except 96h. In intestine, enzyme activity was graduallydecreased in all exposure and an increase was found during 96h. In brain, the enzyme activity wasobserved at all exposure periods except 96h
