Abstract :

Rapid growth of cities across the world is leading to heavy pressure on water resources with many urban centers facing crisis in water supply. Still, the water quality supplied is not-potable, services are irregular, water wastage is high, with much of the poor strata not having access to piped water, and corporations do not collect the funds needed for maintenance and operation. To address this crisis, many urban centers are investing in expensive water supply rehabilitation and expansion projects, often with the assistance of the World Bank and other agencies. However, little is being done to protect the sources of water. Urban watersheds and their biodiversity are being degraded by uncontrolled use, resulting in poorer water quality; threats to human health, seasonal water shortages & aquifers are being polluted and depleted. As the water crisis continues to become severe, there is a dire need of reform in water management system and revival of traditional systems. Scientific & technological studies need to be carried out to assess present status so as to suggest suitable mitigative measures for the revival to traditional system/wisdom. Revival process should necessarily be backed by people's initiative and active public participation. In order to properly manage the changing conditions, knowledge and estimation of the available resources and applying their relation with the population is of utmost importance. The paper deals with extraction of such information with the help of spatial techniques. This paper deals with estimation of the amount of rainwater harvesting potential for micro watersheds of Nag river watershed using geo-spatial techniques.

Abstract :

The aviation industry is governed by very well defined maintenance philosophies. Concurrently, strictly complaint technical procedures/ practices are hallmark of this industry. Therefore, very high quality and costly lubricants are required to support aircraft operations. Oil is used primarily as lubricants, power transmitters and coolants in aircrafts. Further, due to flight safety considerations, the change-over period for oils are very well defined and strictly complied. Reclamation/ recycling of used oil are an accepted fact worldwide in automobile industry. The reverse supply chain starts at the repair depots/ workshops and ensure safe collection/ transportation of used oil back to a central warehouse/ reclamation plant where it is re-processed. In the aviation sector, there is a value proposition which can generate ancillary revenue, by reclaiming the used/ waste oil. It is estimated that the Scheduled Domestic carriers consumed (or re-charged) over one lakh liters of lubricant (hydraulic and engine) oil for 9.35 lakh hrs of cumulative flying done in year 2013. The consumption pattern of engine oil/ hydraulic oil can be estimated on flying hours basis. These figures can be used to project the recoverable quantities of oil at 75% efficiency using existing technologies. This paper discusses this unique possibility by conceptualizing a reverse supply chain model for collection/ transportation of used aviation oil. Various technical procedures, relevant literature and various case studies on handling waste oil were reviewed to develop the basic framework for the Reverse Supply Chain model.

Abstract :

A new kind of zero order dispersion with Hexagonal structure and triangular lattice photonic crystal fiber of different air-hole diameters in cladding region is projected and the dispersion is investigated employing a compact 3-D finite distinction frequency domain method with the anisotropic perfectly matched layers (PML) absorbing boundary conditions. The proposed result is through numerical simulation and optimizing the geometrical parameters like by changing the diameter of holes (d) for photonic crystal fibers in triangular lattice structure. After analyzing all the result, it has been demonstrated that it is possible to obtain zero dispersion at 1.55µm wavelength which lies in the wavelength range of 1.53 to 1.65 μm with low confinement losses from a six ring into which ring are designed as elliptic and circular. The best choice of material for the designing purpose is silica material, which has refractive index 1.458.

Abstract :

The photonic crystal fibres (PCF) are more better than conventional optical fiber. In this paper we proposed a new design of photonic crystal fiber using borosilicate material. Triangular lattice is used with linear and elliptical waveguide in cladding. The PCF are very useful for optical transmission. For better transmission, ultra flattened dispersion or near to zero dispersion is desirable. Finite Difference Time Domain (FDTD) method and transparent boundary condition (TBC) is used to evaluate the dispersion property in a high-index core PCF. Through reproduction and optimizing the PCF, we find that the projected photonic crystal fibres give flattened dispersion in wavelength range of 0.5μm to 2.0 μm. This method produced best result at third attenuation coordinate (1.55μm) over 1.4 μm to 1.8 μm wavelength range and found the dispersion and ultra flattened that has better performance than conventional photonic crystal. PCF can be used as a dispersion compensating fiber in optical window with high potential.

Abstract :

Painting the wall is normally done manually, which is very difficult and troublesome for humans to work in an upright position and also very dangerous for eyes and skin. Due to fatigue and surrounding environment, painting might not even all over the wall. To overcome these difficulties, an intelligent pneumatic wall painting machine has been designed and fabricated using vision and neural system. The machine has the arm which can extend up to 25 feet by carrying the pneumatic spray gun. The camera in the arm captures the image of the wall and the obtained image has been processed and gives as the input to the trained artificial neural network. The output from the network is used to control the pneumatic pressure supplied to the air gun. A part from the automatic control, manual control switches are also used for the operation. Thus the developed intelligent machine is a low cost machine with automatic and manual control for perfectly painting the wall with reduced human fatigue, time and paint, even with an un uniformly painted wall.

Abstract :

Clays mineral, especially smectite type, are widely used as barriers in landfills to avoid pollution of subsoil and groundwater by leachates containing heavy metals. Hence it is important to study the adsorption of metals by these kinds of clays since it’s a low cost material and frequently presented in nature; accordingly many researchers pinpoint their interest to apply this material as adsorbent to reduce heavy metals from wastewater. In this investigation, we have tried to evaluate adsorption properties of local clay, denoted ArB, collected from south of Tunisia (Stah Gafsa), to remove lead and cadmium from aqueous solution. This clay was tested at the first time to remove heavy metals for environmental protection. First of all clay was purified and characterized by several physico-chemical methods. Results approve the general smectite group of the sample with fraction of illite and kaolinite. The adsorptive properties of purified sample, Na-enriched smectite denoted ArP, in cadmium and lead annoying aqueous environment were studied in a batch adsorption system. It was found that the amount of adsorption of metal ion increased with the initial solution pH, metal ion concentration, and contact time, and with the amount of adsorbent. Adsorption isotherm show an apparent selectivity with the following order: Pb2+> Cd2+. The percentage of ion removal by ArP in certain experimental conditions can reach 98% for cadmium and 57% for lead.

Abstract :

Modern grain storage and preservation system requires scientific and technologically skills, hence the need to incorporate the principles of good management starting from entrance of grain to the storage silos or warehouse and their release. Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) is the integration of computers into the design and production process to improve productivity. In order to reduce to minimum level the menace of grain- product losses as it affects farmers in Nigeria, this research had made use of CAD/CAPP to solve operational and management problems associated with grain reception procedures at the National Strategic Grain Reserve program of the Federal Government of Nigeria. Computer aided management system was developed to minimize time wasted during grain reception at the 12 operational silo complexes of the Federal Government of Nigeria. Queue theory was employed to monitor the time of inter- arrival, arrival, waiting and length time of grain. The modules were coded in Pre– processor Hypertext higher programming language using Dreamweaver platform and Structural Query Language as database management system. Losses were recorded during the reception and release of grain out of the National Strategic Grains Silo Complexes in Nigeria. These losses are enormous as a result of poor and manual handlings and other human factors. The results showed that introduction of Grain Storage Monitoring Software (GSMS) to grain arrival and reception management would reduce the waiting time from 10.hrs to 1.9hrs, while queue theory analysis showed that timely servicing of suppliers of grains and food materials to the Government warehouses and silos would ensure no time loss.

Abstract :

While Textile Effluent is discarding in to the nearby water bodies becomes a significant threat to Environment mostly to the aquatic life. The objectionable properties like turbidity, strong color, strong odor, toxicity and alkalinity etc. Coagulation and flocculation is simple and rapid technique. This is most often used pretreatment technique to treat the effluent. Aluminum sulfate (alum), ferrous sulfate, ferric chloride and ferric chloro-sulfate were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminum based coagulants has become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer, chitosan in treatment, which are more environmental friendly. Moreover, chitosan is natural organic polyelectrolyte of high molecular weight and high charge density which obtained from deacetylation of chitin. The experiment was carried out on textile industry wastewater by varying the operating parameters, which are chitosan dosage, pH and mixing time in order to study their effect in flocculation process by using chitosan.

Abstract :

In this study, we investigate the pricing of interest rate options in three arbitrage-free models with jump process which are Vasicek and Cox-Ingersoll-Ross (CIR) models of stochastic interest rate and Heath-Jarrow-Morton (HJM) model for stochastic forward rate. Solutions of Hull and White (HW) type model with jump are derived directly using a system of differential equations and the relationship between short rate and forward rate processes which is obtained under the extended restrictive condition on jump and volatility can be used to have the formula of bond price. We also analyse the option values of three proposed jump models obtained by Monte Carlo simulations.

Abstract :

In this paper, a novel strategic approach is proposed to locate distributed generation (DG) in the primary distribution network under (N-1) line outage security criterion. The static voltage stability margin (VSM) using continuation power flow (CPF) is determined for each line outage condition and based on corresponding reduced VSM is considered as a criterion for line outage ranking. The critical bus is selected for DG location under worst line contingency condition. Using repeated power flow (RPF) approach, the DG value is increased up to network becomes normal state. At this stage, the TVAC-PSO algorithm is implemented to optimize system voltage profile and so loss minimization. The proposed approach is tested on standard IEEE test systems and is found to be very effective in identifying the suitable location and size of DG for voltage stability margin enhancement.

Abstract :

The main objective of this study was to optimize the parameters that influence the extraction of a cationic dye acid orange 10 (C16H10N2Na2O7S2) from an aqueous solution, by an emulsified liquid membrane (ELM) consisting of Aliquat336 as the extractant, Span80 as the surfactant and cyclohexane as the diluents. The internal phase used was sulphuric acid.  The extraction process parameters were studied using a statistical method of experimental Plackett-Burman design. Effects of parameters on the extraction yield were analyzed statistically and a mathematical model of the yield according to different parameters was developed, Main effects were studied and levels of all parameters correspondent to the best yield were determined. The concentration of span80 and the acidity of the internal, the composition and the proportion of the membrane were the most important factors for the extraction yield of AO10. Under optimized operator conditions deduced from main effects, a validation of the model was carried out; the extraction yields given by the polynomial models according to the coded and uncoded parameters and the extraction yields obtained experimentally, were very close comparatively.

Abstract :

The present paper proposes a very simple method for fault sorting of three-phase transmission line, which is based upon the wavelet transform and Genetic Algorithm. Three phase currents of only one end are measured and features are extracted using discrete wavelet transform. These features are then used as inputs to the genetic algorithm. The training data set for genetic algorithm is obtained by simulating the ten different types of faults using various values of fault inception angles and fault resistances, so that the accurate results can be obtained. The proposed genetic algorithm employs twenty inputs and only one output for classifying the faults. The uniqueness of the proposed method is that all the features, inputs used in developing the algorithm are normalized, so that the method can be used for any system without any substantial changes. The simulation of the three-phase transmission line network and wavelet transform analysis are achieved in the tool boxes of MATLAB® and genetic algorithm codes are also written in MATLAB®.

Abstract :

Most previous investigations of microbial interactions with truffle have been conducted within the soil environment and have not considered effects on post-harvested truffles. After harvest, truffles spoil easily and quickly within 4 days.  This study evaluated the efficacy of bacteria isolated from fresh Tuber aestivum fruits ascocarps as biocontrol agents against the bacteria and fungi responsible for spoiling truffle fruit. Effects of acetic acid (12 %-v/v) and citric acid (10%-w/v) as inhibitors of isolated spoilage bacteria were also tested. An antagonism test between microbes extracted from unspoiled truffle microorganisms was performed against microbes responsible for spoilage of truffle fruits. Spoilage bacteria were identified. Truffle fruits immersed in a supernatant from antagonistic bacteria culture medium contributed to non-spoilage and resulting in storage of fruit at room temperature for more than two weeks without spoilage development. In addition, acetic acid (12 %-v/v) inhibited all tested spoilage bacteria. However citric acid (10%-w/v) had no inhibitory effect on spoilage bacteria. The results showed a high rate of antifungal activity among the bacterial isolates, indicating that truffle may be a common source for selection of microorganisms with important biotechnological potential, and may be useful for further biocontrol of food, plant, and soil-borne pathogenic bacteria and fungi.

Abstract :

Soluble solids content and acidity are major determinants of fruit taste in citrus. It has been observed that fruit from top-grafted trees retain higher acidity than on-root stock in ‘Shiranuhi’ mandarin [(C. unshiu x C. sinensis) x C. reticulata]. In order to identify cultural practices that affect acidity in ‘Shiranuhi’ mandarin, we tested the effect of cover (fruit bagging) on fruit quality(size; soluble solids; acidity) from 50 days after anthesis, to 90 days postharvest in 7-8 year-old ‘Shiranuhi’ mandarin trees secondary grafted onto satsuma mandarin scaffolds on trifoliate orange rootstocks. Transverse diameter and longitudinal length were smallest in fruit covered with the black printed paper. No differences were observed between treatments in soluble solids content, but acidity in fruit juice was higher in non-bagged controls from 95 days after anthesis to 90 days postharvest. Citric and malic acid content was highest in the control at 125 days after anthesis. Mean temperature was 0.3-0.7℃ higher than ambient in fruit bags during fruit maturation. These results suggest higher temperature during growth and ripening may be responsible for lowered acidity in bagged ‘Shiranuhi’ mandarin fruit.

Abstract :

One challenge in node-link diagrams is how to efficiently provide a node placement or layout that will yield a meaningful graph visualization. For simple structures, the system needs only a set of aesthetic choices to provide a useful graph—sometimes even a hand-drawn visualization could suffice. But for large, complex structures, effective layouts are harder to create, which motivates continual interest in graph layout algorithms as an integral part of visualizing complex networks. Although most traditional work involves developing more efficient layout methods for static graphs, more recent efforts have also focused on finding effective ways to generate dynamic graphs of time-varying networks. This paper discusses the various aesthetic criteria's which improve the readability of graphs and helps in how to choose proper layout algorithm for specific data to make the visualization better. This paper also discusses the different graph layout approaches which are used as the basis for developing many other new and improved graph layout algorithms helping in better visualization of graphs. Some easy-to-program network layout approaches are discussed here, with details given for implementing each one. This paper is mainly focused on the basic graph layout approaches which are used in "GUESS"  the graph visualization and exploration software. This paper is also intended to beginners who are interested in programming their own network visualizations, or for those curious about some of the basic mechanics of graph visualization.
