Abstract :

One frequently encountered problem in building and applying Geographical Information Systems (GIS) is to find the optimal path (shortest path). Bus route expansion is one demonstration example. The essence of this problem is the implementation of two options. The first is selecting potential locations for bus stop, and the other is choosing one optimal route which go through some potential locations with “lowest cost”. In the past, the problem of finding the optimal path in GIS will be implemented under hard computing. However, geographical data are inherently inaccurate and imprecise. Therefore, a fuzzy logic approach will make the solution to the problem of optimal path becomes more flexible. In this paper, the authors present four steps to expand bus routes in Thai Nguyen city of Vietnam in which using the fuzzy optimal path algorithm. It includes map database collection, map overlay (to identify potential locations), data fuzzification and applying the fuzzy optimal path algorithm.

Abstract :

Thermal conductivity of materials plays an important role in the efficiency of heat transfer in heat exchangers. Generally it is the practice of utilizing pure water for heat extraction from the processed fluids. Therefore it is essential to remove the heat from the fluid and slurry at a particular heat transfer rate in this investigation. A nano fluid, containing Al2O3 in pure water is utilized to remove the heat from the hot fluid with various concentration of Al2O3. The result revealed that the nano fluid is more efficient in heat removal and as well as show higher thermal conductivity. The increase in the addition Al2O3 in water increases the ability of the fluid to extract heat with better efficiency. The results show that the thermal conductivity is increase by 2 to 5 times, depending on Al2O3 concentration in the fluid.

Abstract :

This The morphometric characteristics and relative growth of the blue swimming crab Portunus segnis collected in the Gulf of Gabes were examined. A total of 634 individuals of P. segnis were analyzed, being 335 males and 299 females. The allometric relationships between the characters of this set suggest that most relationships are isometric. The carapace width/length- weight relationship was studied in both sexes of crab. The exponential values (b) for the carapace width-total weight relationship was distinct between the sexes with a positive growth pattern in weight for males, and a negative allometric pattern identified for females. Males were significantly larger and heavier than females, the expected pattern to many crabs.  An analysis of variance indicates that there is a significant difference between sexes with respect to the carapace width-weight relationship. A correlation between carapace width and weight were encountered for males and females. The statistical analysis of chelar propodus length within sexes indicated a mirror-symmetry in this species, which provides more stability and balance to individuals. The condition factor ranged between 0.00691 and 0.34767 with a mean of 0.0582. The condition factor decreased with an increase in crab size.

Abstract :

Indoor air pollution is a growing health concern in the present urbanized world caused by increased use of radioactive materials. Many studies are being done to estimate and identify the sources of radioactive energy and its incidence in the indoor environment and subsequent implications on the human health. Radon is a color and odorless gas and enters indoor environments from ground surfaces and concentrates over time in absence of ventilation and the release from the soil varies on many ambient factors that changes temporally and spatially. The indoor concentrations of radon gas have serious effect on health and results in cancer among humans from the long-term exposure. The paper emphasizes to analyze the impact of radon gas in indoor and outdoor locations in Muscat region and compare the emissions with other GCC countries. Experiments are done at three stages using equipment by choosing some prominent building locations in Muscat region to estimate the indoor and outdoor levels of radon gas and consequently assess the implications. Gamma ray spectrometers are employed to detect the radiation from the chosen locations and the values recorded. The investigation reveals significant amounts of radon gas detected in comparison with other Arab countries in GCC but substantially less from developed countries. The study shows the concentration and presence of radon gas in indoor habitats relates to construction materials and the level of ventilation. The results indicate that radon gas concentrations during the study showed fluctuating intensities weekly with generous changes during each week.

Abstract :

This paper deals with basic information regarding the face recognition and whole parameters that effects the face structure and face shape. For the calculation of age, clients utilize age function combined with aging way. Face recognition is most difficult field of pattern recognition, however research in this field almost attains constancy with new difficulties emerges with time, and the research again towards the problem encounters due to aging, an automatic age technique utilized for strong face recognition is given briefly. Then user use age, commonly vector generating function or feature vector of real image to create synthesized feature vectors at target age. User uses a structure and texture vectors to show a facial image by projecting it in Eigen space of shape or texture. Images in courtrooms for evidence, graphics in newspapers and magazines, and digital graphics used by doctors are few instances that needs for pictures and not using a manipulation. Earlier, SVM algorithm failed in many instances in detection of forged picture. For the reason that single characteristic extraction algorithm, just isn't capable to include the certain function of the pictures. So you can overcome drawbacks of existing algorithm. We can use meta-fusion technique of HOG and Sasi elements classifier also to beat the drawback of SVM classifier.

Abstract :

It has been observed from the research work that Newcastle disease Virus has no cure and the prophylactic vaccines available are not potent enough to eliminate the Newcastle disease virus, thus, it is pertinent to carry out research on Newcastle disease virus in order to proffer solution to the menace. The aim of this study is designed to; determine the inhibitory property of ethanolic extract of Harungana madagascariensis  root on Newcastle disease virus in chicks, determine the histopathology of the extract on the chicks and to equally determine the number of organic components of the extract. The inhibitory property of the crude ethanolic extract Harungana madagascarieniss roots on Newcastle disease virus was studied in two weeks old chicks. 0.2ml of LD50 concentration of the virus was injected into the chicks intramuscularly. An hour later, after the infection of the Newcastle disease virus, they were fed with graded concentration of the extract (10mg/ml, 50mg/ml, 100mg/ml and 250mg/ml) and were observed for inhibitory/antiviral activity for 24-96 hours. Significant inhibitory property was observed (P <0.05) at the concentration of 100mg/ml of the extract. Therefore, the result shows that crude ethanolic extract of Harungana madagascariensis has inhibitory property at the concentration of 100mg/ml and the extract did not have any toxicological effect. Further studies should be done on the inhibitory property of the plant at other concentrations and purification of the plant for its chemical constituents should equally by studied.

Title : A Comparative Study of Some Estimation Methods for Multicollinear Data

Abstract :

This article compares different estimation methods specially designed to combat the problem induced by multicollinearity using real life data of different specifications and distributions. From the mean squared error of the samples studied we observed that Partial least square came up as the best estimator among the methods we studied. Stepwise regression performs better when the predictor variables are highly correlated. Under the ridge regression study the smallest eigenvalue of the predictor variables of the original data was used in determining the ridge parameter of ridge regression since the variances of some of our samples cannot be estimated by ordinary least squares regression. From our results we found that among all the methods we studied PLSR estimator stands the “best”, followed by the stepwise regression and then the PCR estimator in predicting the response variable. We are not surprise that RR estimator stands the least among the methods since it is known as biasing estimator and more useful in estimating the parameters of the model.  We also wish to state that PLSR is efficient in prediction when the sample size is very small.

Abstract :

Synthesis of visible light driven ZnO nanospheres is of great importance in practical application, such as water purification. In this paper, cysteine capped ZnO (CCZ) nanospheres were prepared by microwave based biomolecule assisted chemical precipitation method. The CCZ nanospheres were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray spectrum (EDAX), photoluminescence (PL). The photocatalytic activity of CCZ nanospheres was estimated using Rhodamine B as model pollutant under visible light irradiation. The experimental results exhibited that cysteine molecule were doped into the lattices of ZnO nanospheres and shows noticeable increase in visible-light harvesting ability. The CCZ shows the highest photocatalytic activity than that of bare ZnO counterpart. The enhanced photocatalytic activity of CCZ nanospheres is ascribed owing to its adsorption capacity and enhanced visible light harvesting ability.

Abstract :

In this paper, the numerical solution of fractional differential-algebraic equations (FDAEs) is considered by Shannon wavelets. We derive the wavelet operational matrix of the fractional order integration and by using it to solve the fractional differential-algebraic equations. Two illustrative examples are presented to demonstrate the applicability and validity of the wavelet base technique. To highlight the convergence, the numerical examples are solved for different values of order. The results obtained are in good-agreement with the exact solutions. It is shown that the technique used here is effective and easy to apply.

Abstract :

This paper reviewed bioremediation system applied for hydrocarbons removal form produced water in Heglig field using Phragmites Australis plant, to produce clean water and recover valuable materials from produced water with minimal negative impact on the environment. To evaluate effectiveness of bioremediation system three quantitative analysis methods (gravimetric method, spectrophotometric method and IR method) were used for determination of oil in water before and after treatment using bioremediation technology for Heglig field produced water. The results of analysis showed that determination of oil content by IR method is more accurate than by spectrophotometer and gravimetric method. According to the IR results the effectiveness of bioremediation system for hydrocarbons treatment by Phragmites Australis plant can remove more than 86.72% oil content of produced water. One qualitative analysis method (GC method) was used for determination of oil in water before and after bioremediation treatment for Heglig field and the results showed that most hydrocarbons treated by bioremediation system are n-C10 and n-C11 while components of high number of carbon (n-C22 to n-C29) are almost untreated.

Abstract :

In this research work, trajectory tracking of DC motor is established. A hierarchical controller with the dc motor based on differential flatness and the dc/dc Buck converter is designed. In dc motor, angular velocity tracked from a desired velocity trajectory from the desired voltage profile. The inner current loop and the outer voltage loop of cascade control is modelled. The desired angular velocity trajectory is well tracked and the controller is robust in such dynamic operating conditions. The actual value follows the trajectory with time delay and reduced magnitude in simulation. So controller gains are introduced to overcome these issues. Along with that, hardware is to be implemented for the simulation model of overall system. It is important that these types of abrupt variations do not happen in practice at the same time, or with such large variations regarding their nominal values.

Abstract :

This paper aims to solve inventory models without depending on calculus. This is an important issue such that many practitioners who are not familiar with calculus, then, can realize inventory models. There are more than one hundred papers that had worked on this research issue, however, most of them have overlooked the positivity of the item in a square root, and then some researchers can claim that they created a simplified solution procedure for algebraic approach. Their derivations are partially corrected under the restriction that the positivity of the sign of the item inside the square root is preserved. However, for other cases, when the positivity of the sign of the item inside the square root is violated, then their results will contain questionable derivations. Ignore the sign of the term inside a square root is a serious matter in algebraic methods such that other practitioners should provide revisions to constitute a well-defined algebraic approach. In this paper, we provided a detailed analysis to construct criterion to guarantee the existence and uniqueness of the optimal solution by algebraic method. Our findings will provide a prior work for researchers to further study inventory models under algebraic method environment.

Abstract :

The selection of AM fungi is required to characterize the native AM fungi population from the soil types. The recent studies have clearly reported that these fungi are host preference in enhancing the growth, yield and nutrient. In the present study six indigenous AM fungi were selected from chillies growing fields of Haveri. These six AM fungi were inoculated to cultivar Sankeshwar of Capsicum annuum L. at green house conditions. Plants harvested at 60 and 90 days after inoculation. The results obtained from the experiments were clearly evidence that the positive influence of Glomus macrocarpum Tulasne & Tulasne.  on cultivar Sankeshwar of Capsicum annuum L. plants in increasing plant height, root length, fresh weight of shoot and fresh weight of root, % root colonization, spore number and P uptake in shoot and root. Similarly the improvement of number of fruits was higher. The second AM fungus Rhizophagus fasciculatus (Thaxt.) Walker & Schüßler was influenced in all the different parameters it is followed by Glomus mosseae respectively. And thus an indigenous AM fungi play an important role over the control plants or non inoculated plants. This is mainly due to AM fungal species differ considerably in their efficiency to colonize and influenced plant growth biomass yield and nutrient uptake.

Abstract :

Ground water quality of Bailadila iron ore mine area & its peripheral, Dantewada district, Chhattisgarh have been studied. 20 samples were collected from hand pumps in summer season and analysed in order to find out water quality index (WQI) and heavy metal pollution index (HPI). Physio-chemical parameters such as pH, electrical conductivity (EC), turbidity, total hardness (TH), Ca+2 hardness, Mg+2 hardness, total dissolved solids (TDS), nitrate, sulphate, chloride were analyzed with standard procedure and instrumental techniques. Some heavy metals such as Al+3, Cr+6, Pb+2, Fe+2 and Zn+2 were also found out by Nova 60 spectrophotometer and Atomic Absorption Spectrophotometer (AAS). The results were compared with standards such as Indian Standard Specifications for drinking water (IS 10500), World Health Organisation (WHO) and United States Public Health Service (USPHS). From the analysis, it was found that EC, turbidity, Mg+2, sulphate, nitrate and heavy metals such as lead (Pb+2) and iron (Fe+2) are higher than the permissible limit. It was also found that only 20% of samples were soft and rest are hard water. The samples having higher iron and turbidity are of lower pH value. WQI and HPI are found as 85.143 and 85.026 respectively. It shows that ground water quality of Bailadila iron ore mine area is very poor and not safe for drinking purpose.
