ThesisItem Open Access A study of thermo-magnetic effects on static state of cholesteric liquid crystal between two hot co-axial circular cylinders(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Gangwar, Sukhdev Singh; Sharma, A.K.Liquid crystal the fourth state of matter is observed between the crystalline solid and amorphous liquid states. It exihibits the properties of liquids as well as that of crystalline solid state. In the present study we have considered an infinite static layer of cholesteric liquid crystal lying between two infinite hot co-axial circular cylinders in the presence of azimuthal magnetic field when both the cylinders are held at different temperatures and are lying at rest. We have examined the thermo-magnetic effects in this problem. After obtaining the system of governing differential equations we have solved it numerically by Newton Raphson method. The results are then graphically plotted. It has been observed that orientation of molecules varies with the variation of magnetic field and temperature gradient parameters.ThesisItem Open Access A study on effects of uniform magnetic field on flow of cholesteric liquid crystals between two relativaly moving parallel hot plates(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Meena Kumari; Sharma, A.K.A study has been conducted on the flow of an incompressible cholesteric liquid crystals with director of unit magnitude between two infinite relatively moving parallel hot plates with the objective: To examine the effects of uniform magnetic field in (x,y,z) directions in the plane of the lower plate which is at rest while the upper plate is motion with a uniform horizontal velocity and the two plates are maintained at different temperature. Differential equations governing the two components of horizontal velocity ( u) and (v) , orientations of directors (θ ) and (Φ) have been formed and solved by using couple stress boundary conditions. In the solution of these equations, we observe that there is no effect of magnetic field on the two velocity components, but they increase with the increase in thermal gradient parameter (E1).The effect of magnetic field on the orientation of molecules (θ) and (Φ) causes variation in their profile.ThesisItem Open Access A study on effects of uniform magnetic field on flow of cholesteric liquid crystals between two relativaly moving parallel hot plates(G.B.

Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Santhosh, M.; Bais, R.K.S.The poultry industry is the fastest growing sector among Indian agriculture sectors and today India occupies 4th and 6th place in the world for egg and broiler production, producing 41 billion eggs and 1000 million broilers every year. The impact of such a massive growth of the poultry production has not been felt by masses because of the population explosion. The per capita availability of 40 eggs and 1 kg meat is far behind the ICMR recommendations and the gap can be bridged by developing superior layers following appropriate breeding strategies. In view of the above, the present study was undertaken to construct and evaluate the multi-trait selection indices for improving egg mass in a pure strain (N) of White Leghorn maintained by a commercial poultry heeding organization. The phenotypic and genetic parameters were estimated in the flock under study. The heritability estimates were found to be low for EM40, EP40, EW40 and ASM, whereas the moderate heritability estimates were reported for BW20 and BW40. The egg mass was having a high positive correlation with egg production while egg weight had lower positive association with egg mass. Thus, selection for egg mass seems to be appropriate for improving both egg number and weight. A total of fifty seven multi-trait selection indices were constructed in different combinations incorporating six, five, four, three and two traits as the selection criteria with the selection objective in all the cases being improvement of egg mass only which comprises the aggregate genotype. The multi-trait selection index (IMT1) including all the six traits was found to be the most desirable with the gain in all the individual traits in favourable direction. Based on the estimates of genetic cost of restriction of different traits, the egg mass was found to the have the highest contribution followed by EW40, EP40, BW20, BW40 and ASM. The direct and correlated responses in performance traits from individual selection of pullets were estimated and on comparing with the best index (IMT1), the selection for 20 week body weight was found to be the most desirable with respect to relative accuracy/ efficiency and gain in individual traits particularly the egg number and egg weight for the population under study.ThesisItem Open Access Mathematical modeling of impact evaluation and phytoremediation of pulp and paper industry effluent(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Sanjeev Kumar; Dube, K.K.The problem of pollution as a consequence of increased industrialization is, by now, a well-known phenomenon. In case of pollution in water, the problem is more serious. Not only industrial wastes, but also discharge of domestic waste water and sewage can be major pollutant. In present investigation three mathematical models first on the impact of pulp and paper mill effluent on soil microbial biomass, second on the effluent impact on soil microbial activities and third on phytoremediation of pulp and paper mill effluent employing Eichhornia crassipes have been developed. In first and second models the variates taken into consideration decreased exponentially with increase in the distance from the source of pollution, whereas in the third model similar decrease was observed with the increase in duration of phytoremediation. The former two models are valid for only point source pollution impact and not for non-point source pollution where varieties of unknown factors contribute towards ill impact of pollutants. The third model is equally prominent for devising technique to get rid off the ill impact of the industrial effluent. The mathematical model presented here provides a fairly accurate prediction of the ill impact of pollutant present in pulp and paper mill effluent and its remedial measure employing plant like Eichhornia crassipes. These models could be used for predicting the ill impact of other industrial waste water and their removal through phytoremediation technique, as well.ThesisItem Open Access Analysis of time series and stock market behavior using wavelet methods(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-05) Anuj Kumar; Sharma, A.K.Post liberalization, the development of new techniques and ideas in econometrics have been rapidly growing over the last few years. These developments are now being applied to a wide variety of fields and in analyzing the stock market behavior. Specially the area of analysis of financial time series is catching the attention of big business houses as they are now contemplating on optimizing the business process in order to achieve best estimate of production planning over the long span of time and also to sustain the growth momentum. Economic and financial time series are nonstationary in nature and exhibits changing frequency patterns over the time. Wavelet analysis is one such tool for analyzing non-stationary data. Parameterization of wavelet families allows one to generate infinite number of wavelets for the different choices of selection for analyzing the financial time series. In present work, “Analysis of time series and stock market behavior using wavelet methods” we have proposed a simpler method to generate parametric families of orthogonal wavelet and used it to generate the ‘6-tap Daubechies wavelet filter’ in a straight forward manner. The wavelet based concepts have then been employed to study BSE and NSE indexes financial time series using index data from April 1990 to March 2006 by decomposing index based financial time series into time-scale components using the MODWT (Maximal Overlap Discrete Wavelet Transform) analysis. The most commonly used measure to analyze the stock market behavior is the wavelet correlation analysis, we have used it for the analysis of BSE and NSE indexes financial time series. The work embodied in this thesis serves as intuitive guide for analyzing the time series and can be of use for the predictions based on it by using the newly developed wavelet technique.ThesisItem Open Access Study on soft computing techniques for forecasting(G.B.
