Basically biometric system used for identification purpose in this we have two types of attributes physical and biological. The physical attributes are classified as fingerprint, face recognition, palm, voice and biological attributes gait, keystroke etc.In biometric system is that whatever changes the intruder has done with the template it should not be accepted by the biometric system. This paper outlines about the approach based on multimodal biometric (E g. Fingerprint and Iris) which fused together for recognition. This multimodal biometric system is composed of three modules 1) Feature Extraction 2) Fusion of Multimodal biometric template creation 3) Cryptographic key creation. Firstly features like minutia points from fingerprint and texture from iris are extracted. These features fused together to construct a single multi-biometric template. Template protection gives privacy which offers security.

Environmental impact of pesticides consists of the effects of pesticide on non- target species. Over 98 percent sprayed pesticide with agricultural sprayer reach a destination other than their target species because they are sprayed across agricultural fields. Rum off or wind drift can carry pesticide into aquatic environment, grazing areas, human settlement and undeveloped areas potential affecting other species. Over a time period repeated application increase resistance, while it affects the past resurgence. Each pesticide set of environmental concern, such undesirable effects have led much pesticide to be banned while regulations have limited and reduced the use of others in agricultural fields. However, the global spread, demand and dependence on pesticides as a management tool for crop protection had increased a detrimental effect on farm workers and stake holders. The result of the field studies in the study zone, estimated at least 164 cases of contracted diseases, 103 acute poisoned, 101 hospitalized and 28 untimely dead of farmers and farm workers. Available information raises in this study over 10-20% population of natural honey bee use for food were declined. Investigation carried out in the studies that 59 percent of sprayer operators, farm workers and stakeholder are not using personal protective equipment.

In this paper presents about control of Bioreactor useing Artificial Neural Network. bioreactor has become an active area of research in recent years. This is partially attributable to the fact that bioreactors can be extremely difficult to control. Their dynamic behavior is invariably non-linear and model parameters vary in an unpredictable manner. Accurate process models are rarely available due to complexity of the underlying biochemical processes. A feedback controller is needed to account for disturbances and time-varying behavior. Neural network based model predictive controller designed for the control of bioreactor. In the first step the neural network model of bioreactor is obtained by levenburg- marquard training the data for the training the network generated using mathematical model of bioreactor.

These study deals with optimization of newly design ball burnishing tool is used carried out experiment on conventional lathe machine with burnishing process parameters using taguchi analysis method. The work piece and ball materials used is Aluminum Alloy 6061 and high chromium high carbon with 8mm diameter. The levels of input process parameters are selected on basis of one factor at a time experiment are burnishing force, burnishing feed, burnishing speed and number of passes. The response parameters is hardness. The optimal parameters for hardness are as follows: burnishing speed 250 RPM, burnishing feed rate 0.06 mm/rev, burnishing force, 8 Kgf, No. of passes 5.

This paper gives a comparison between the horizontal axis wind turbines, or HAWTS, and the vertical axis wind turbines, or VAWTS. The two types of wind turbines are used for different purposes. Several models of both types are presented from previous research.

Wind has a very intermittent nature, its behaviour and speed are directly affected by several factors, specifically the nature of the environment and the height that wind blows at. Wind behaviour at urban large city areas and urban suburban areas is completely different than such behaviour at open terrain and flat unobstructed areas, wind turns to be more disturbed and turbulent and wind speed is reduced due to the existence of several obstructions, mostly buildings either single storey or medium rise or high rise buildings in addition to trees. As well, the height at which wind is blowing, the lower height the more disturbed wind the less wind speed, such effect is maximised in urban areas and near to the ground level. This paper aims to estimate and generate, in urban Armidale NSW, Australia, an annual typical daily wind speed for heights equal and less than 10m. A numerical method is applied to calculate such wind speed at urban Armidale at various heights (10, 9, 8, 7, 6, 5 & 4) m utilising an already previously generated typical wind speed reference year (TRY) of Armidale based on historical meteorological wind speed records measured at 10m height at Armidale's Airport Weather Station (AWS) over a period of 20 years (1994 to 2013). Achieving such a database of typical reference year of daily wind speed at heights equal and less than 10meters in (m/s) is an added value to the micro-scale wind energy generation systems, ranges from 0.5 kW to 10 kW, as such systems involves micro-scale wind turbines would be operating at heights considered at this study.

Fe(III) ion doped Ni L-Histidine Hydrochloride monohydrate crystals (Fe(III)-NiLHICL) are grown at room temperature using slow evaporation technique. The Fe(III) doped NiLHICL crystals are characterized by spectroscopic techniques such as X-Ray diffraction studies, Electron Paramagnetic Resonance(EPR), Optical Absorption and FTIR studies. Thermal stabilities were studied by TGA/DTA analysis. The powder diffraction patterns of prepared crystals have been recorded and lattice cell parameters are evaluated as a = 1.5286, b = 0.8933, c = 0.6852 nm. From EPR studies, g and hyperfine splitting parameters for Fe(III) ion in the host crystals are determined as g = 2.0301 indicating octahedral symmetry. Crystal field and inter-electronic parameters are evaluated from the optical absorption studies in addition to obtaining the confirmation for octahedral symmetry for the ions in the host lattice. The FT-IR spectrum exhibited characteristic vibrations of the groups present in the crystal indicating bond formation between the metal ion and the amino acid.

The average size of oil palm kernels of unknown variety was used to classify their varietal composition. Engineering properties of oil palm kernels are important for rational design of general- purpose handling systems for oil palm kernels. In this work, average values of size, solid density, bulk density, compressive yield load, hardness, angle of repose, porosity, sphericity, and coefficient of friction were determined for samples of unknown variety of palm kernels sourced from three local markets in Nsukka, Enugu state, Nigeria. At an average moisture content of 6.1% (w.b.), the major diameter ranged between 15.68 ± 2.24 mm and 22.41 ± 2.19 mm with an average of 19.09 ± 2.01 mm. The solid density ranged between 1.00 ± 0.09 g/cm3 and 1.32 ± 0.02g/cm3 with an average value of 1.17 ± 0.13 g/cm3. Other average values were 608.05 ± 14.08 kg/m3 for bulk density; 1022.44 ± 90.56 N for compressive yield strength; 10.41 ± 0.09 kN/m2 for hardness; 37.75 ± 1.33o for angle of repose; 47.4 ± 7.7% for porosity; and 0.74 ± 0.04 for sphericity. The average coefficients of friction were 0.52 ± 0.05, 0.51 ± 0.03, and 0.46 ± 0.06 on plywood, galvanized steel, and glass surfaces respectively. The size analyses results showed that the oil palm kernels used in this study were mixtures of dura, tenera, and pisifera varieties. Moisture content of the kernel was found to influence most of the properties
