Interpretive approach to hydrogeological and geophysical prospection data for the choice of the best boreholes sites in area of fractured rocks in Ivory Coast[ ]


Groundwater research in fractured rocks requires both a hydrogeological study and a geophysical investigation to make the best choice of boreholes favorable location. However, as the electrical resistivities measured don’t absolutely reveal the presence of water, the interpretation of geophysical data often leads to failures. So a new strategy is necessary. In the framework of a water supply program, a specific study was conducted to highlight the interpretation of both hydrogeological informations and geophysical investigations data in order to find the best sites for drilling. An analysis is made for each parameter on every site and a score is given in the form of stars. The number of stars varies between 1 and 3 depending on the quality of the parameter studied. A classification of the sites is made regarding the sum of stars obtained. The site with the highest number of stars is recognized as the best. So the second or the third better site is determined. The boreholes campaign took place and the success rate was 75% in general. But, among the sites identified as priorities, 93% were satisfactory. Finally, the results show that this strategy is interesting but don’t allow quantifying the reserve of groundwater.

A Heuristic Method of Cell to Switch Assignment in Mobile Communication Networks Using Firefly Algorithm[ ]


This paper deals with a design problem for a network of Mobile Communication Services (MCN). The goal is to assign cells to switches in a MCS Network in an efficient manner .It is a NP-Hard problem. We consider three types of costs. One is the cost of handoff between cells. The other is the cost of cabling or trunking between a cell and its associated switch. The third cost is switching cost which includes the cost for transferring a call to other switch. The problem is constrained by the capacity of switch and assignment of a cell to a unique switch. Firefly algorithm is implemented in this paper along with heuristics method to solve the problem of assignment of cells to switches and results are compared with that of Particle Swarm Optimization and Firefly Algorithm.

Iridium(III) Catalysed Oxidation of Threonine by Hexacyanoferrate(III) in aqueous alkaline medium[ ]


The kinetics of the oxidation of threonine by hexacyanoferrate (abbreviated as HCF) (III) ions catalyzed by Iridium trichloride has been studied spectrophotometrically in aqueous alkaline medium at constant ionic strength of 0.5 mol dm-3 & temperature 35? ± 1?.The stoichiometry of the reaction corresponds to a reaction in which one mole of the amino acid reacts with two moles of hexacyanoferrate(III) ion. The reaction rate shows first order kinetics with respect to [HCF(III)], [OH-] and [IrCl3]. The order of reaction is also one with respect to [substrate] at its lower concentration tending towards zero at higher concentrations. A plausible reaction mechanism through a transient complex formation between IrCl3 and amino acid has been suggested. Activation parameters have also been evaluated using Arrhenius equation. A keto acid, ?-keto hydroxy butyric acid, has been identified as the final product of oxidation by chromatographic and spectroscopic techniques.

Ensuring Accountability in Cloud for Portable Devices[ ]


Cloud computing is about moving computing from the single desktop pc/data centres to internet. In cloud computing, user’s data can be put it in the cloud storage and it can be access from the cloud, by the users whenever and wherever they needed. The major feature of the cloud is that user’s data are processed in remote machines, which are unknown to the data owners. Here the security problems are raised. Users fear about their data control, so that they needed to account their data, which are stored in cloud. Accountability is the obligation to act as a responsible steward of the personal information of others, to take responsibility for the protection and appropriate use of that information beyond mere legal requirements, and to be accountable for any misuse of that information.

Light dependent resistor and logic gate based wheelchair control[ ]


When an unexpected accident or event occurs which affects the locomotion of a person, it is necessary to seek the help of wheelchairs which acts as a means of locomotion. Wheelchairs are not only used by physically challenged persons, but also by very aged persons and persons who are affected by quadriplegics i.e. paralyzed over a significant percentage of their bodies. These people will find very difficult task to perform any task that requires even a small amount of force. Here we propose a simple control for wheelchair movement with Light Dependent resistor and logic gates. This system consists of just three LDRs and basic logic gates (EXOR and AND gates). Since this system does not use microcontroller and any complex circuits, it is very simple to implement and very low cost.

Role of Open Source Software and ICT in Disaster Management[ ]


A disaster is a situation in which the community is incapable of coping. It is a natural or human-caused event which causes intense negative impacts on people, goods, services and/or the environment, exceeding the affected community’s capability to respond; therefore the community seeks the assistance of government and international agencies. In this chaotic environment, new alliances, groupings, collaboration, and trust need to be quickly formed between government organizations, civil society, foreign aid groups, and volunteers to effectively muster their energies into a holistic response effort. Information technology can play a valuable coordination role for situation awareness and enable responders to act effectively. In particular, open source software has been found to be a good fit for the dynamic “bazaar”- like environment of a disaster and a good match to the humanitarian codes of conduct. "Free and open source software is increasingly being used in many spheres of development including disaster management. The paper illustrates Disaster management and empowerment of communities in developing nations through appropriate open source applications and also describes the functioning of the “Sahana” disaster management system deployed during the 2004, Indian Ocean Tsunami. Sahana used free and open source software to create number of functionalities.

Rheological and Filtration Properties of Kaolinite Based Drilling Mud[ ]


The demand for drilling mud is on a high increase due to drilling operations ranging from oil wells to ground water bore holes that are being carried out. This necessitates the testing of clays that are abundant and less expensive to make drilling mud. Beneficiated Kaolin clay, barite, bentonite, starch and pipe-borne water were used in the preparation of drilling mud mixtures at various percentage compositions for 12 samples to ascertain the right formulation for the drilling mud; the rheological behavior and filtration property of each of the drilling fluid were measured. Kaolinite clay had a poor permeability as compared to bentonite, the sample with the highest bentonite ratio had the best filtration property; the analysis also showed that high water and barite content has a negative effect on the filtration property of drilling mud. Viscosity measurement were taken within 8.574s-1 and 170.3s-1 shear rates, the sample which contained 8w% of bentonite recorded the highest value of viscosity due to its high bentonite content which led to a significant increase in shear stress at a constant increase in shear rate. When the quantity of bentonite and starch were varied with kaolin there was a decrease in the permeability of the drilling mud, the lower the permeability the better the drilling mud. The addition of local bentonite improved the rheological and filtration property of the fluid which was pseudo plastic, the kaolinite clay only served as a weighting agent.

Fast and Area Efficient RSA Cryptosystem Design Using Modified Montgomery Multiplication for FPGA Applications[ ]


RSA(Rivest-Shamir-Adleman) cryptosystem is one of the most widely used public key cryptosystem.The importance of high security and faster implementations paved the way for RSA crypto-accelerators, hardware implementations of the RSA algorithm.The whole RSA includes three parts: key generation, encryption and decryption process. The RSA operation is a modular exponentiation, and its security lies in its inability to efficiently factorize large integers. Basically, the modular exponentiation with a large modulus is usually accomplished by performing repeated modular multiplications, which is considerably time-consuming. As a result, the throughput rate of RSA cryptosystem will entirely dependent on the speed of modular multiplication and the number of performed modular multiplications. To speed up the process of modular multiplication, Montgomery’s algorithm is recognized as a very efficient solution, in which it replaces the trial division with a series of additions and division by a power of two. Therefore, it is well suited to hardware implementation and consumes less power and uses smaller amount of space in the FPGA compared to other multiply and reduce methods. This work describes the design of an efficient RSA cryptosystem that uses a modified Montgomery algorithm to increase the speed of modular multiplication and a very fast parallel prefix adder ( Kogge- Stone Adder) is employed to reduce the critical path .The design architecture is coded in VHDL, synthesized using Xilinx ISE 12.1 and simulated using Modelsim. Experimental results shows that the modified design obtain the best delay performance compared with the standard design.

The image fusion technique is introduced to generate a difference image by using complementary information by performing log ratio and mean ratio on two original images and by applying DWT based fusion rules. Since the SAR images suffer from the speckle noise, so thatht’s why we proposed an unsupervised distribution-free change detection approach for Synthetic Aperture Radar images based on an image fusion strategy and novel fuzzy clustering algorithm. A reformulated fuzzy local instruction C- means (RFLICM) clustering algorithm is proposed for classifying changed and unchanged regions in the fused difference image. Experiments on real SAR images show that the image fusion strategy integrates the advantages of the log ratio operator and the mean ratio operator and gains better performance. The change detection results obtained by the improved fuzzy clustering algorithm exhibited lower error than its preexistences.

Fast RC Circuit Simulation Using Artificial Neural Networks[ ]


This paper presents a new technique for modeling an RC circuit using Artificial Neural Networks. In the proposed technique, the Artificial Neural Network is trained to predict the dominant characteristics of the full order model representing an RC Tree circuit and removing the non dominant characteristics that doesn't have much influence on the system. The prediction is based on minimizing the mean square error (cost function) between the desired parameters and the actual parameters. Different RC tree circuits of orders 8,10,12 and 20 are used and the reduced model of order 2 is tested. The results are compared to the SPICE simulation program output of the full order model.

Using Multi-Cloud Approach to Enhance the Protection of Patient Privacy in Electronic Health Records[ ]


Today, most hospitals and medical centers have a database to manage patients medical records. It is necessary to collect and access this information everywhere, to increase productivity and improve quality of health cares. Need to access electronic health information across the world and improve the quality of healthcare to patients will highlight importance of using cloud computing architecture in this area. However, despite the benefits of cloud computing applications for health care, the security challenges of cloud should be addressed.In this paper, we introduce and describe a new proposed model called EHR-MCDB (Electronic Health Record with Multi-Clouds Databases). This model will ensure the privacy of persons in a network and multi-cloud environment using cryptographic algorithm and distributed storage. This model is able to store any type of data such as number, string, image, etc. in a cloud environment. the EHR-MCDB prevent from illegal intrusion and access to data in cloud environment and provide services such as data integrity, confidentiality and permanent availability of data in a safe and secure way. The evaluation results of proposed EHR-MCDB show that despite increasing time of information storage and retrieval, System overhead is so that it can be ignored ,against the benefits that it provides, and it does not damage to Normal system activity. Also comparing the proposed model with data distribution method on different servers shows that it is improved almost "about 10% compared to the same multi-cloud model.

Project Managers’ Conflict Management Styles and Its Impact on Project Team Motivation in Nigeria Construction Industry[ ]


Unresolved conflict can thwart project progress and consequently project abandonment as in the case of Nigeria before the emergence of project management. The nascent project management practice in the country has an unequivocal advantage of positioning the construction industry into resolving conflicts that arise within the project. Hence the applications of conflict management styles are exceptionally significant in resolving contending issues in the project, if its adoption by the Project manager motivates project team members. Therefore, this study seeks to identify the consequences of project manager’s conflict management styles on the project team’s motivation, which was achieved by identifying conflict management styles; by confirming the impact of conflict management styles on the project team’s motivation and ascertaining of the most successful project conflict management styles through ranking. Previous researches were looked into for further clarification on the issue, and two sets of questionnaires were given to the Project managers and their team who are professionals in the construction industry in the likes of architects, quantity surveyors, structural engineers, mechanical engineers, electrical engineers, estate surveyors and builders to get their candid opinion on the research. Statistical analysis carried out from the questionnaire suggests that conflict management styles adopted by Project managers have a significant impact as a motivating factor of the project team, and the adoption of confrontation conflict management style is the most effective in solving contending issues in construction project management. The study recommends that conflict management style adopted should be based on the nature of contending issues; the project stakeholder’s demand and the urgency to deliver the project as earlier planned. In addition switch conflict management approach is recommended for the Project managers that intend to finish their projects successfully.

Analysis of FSO Communication Links For Mid And Far Infrared Wavelengths[ ]


Atmospheric attenuations pose biggest challenge in implementing Free Space Optical Communication (FSO) links. Studying atmospheric attenuation as function of cumulative aerosol particle size distribution gives more reliable results rather than taking meteorological visibility as lone factor. Theoretically speaking, wavelengths of Mid IR and Far IR region may exhibit higher immunity against atmospheric attenuation against lower spectral regions but however in practical terms, the effect of totality of system and link parameters negates any such inherit advantage which means that considering the dynamic microenvironment, FSO link does not exhibit any attenuation immunity using higher spectral bands. Increase in transmitted optical power and higher receiver sensitivity along with appropriate selection of photo detector not only improves BER of system but also increases the range of communication.

Partial Mantel Analysis on Estimating the Resembance of Students Performance[ ]


The partial Mantel analysis is a test statistic that is used to measure the resemblance between two distance matrices after controlling for the effect of the third distance matrix measured over the same objects. The method used in this study is; permute the objects in one of the vectors (or matrices). Association on student’s performance of three faculties (Physical Sciences, Biosciences and Engineering) in Nnamdi Azikiwe University, Awka-Nigeria, was used to illustrate the method, where interest is on estimating the resemblance between two faculties students’ performance while controlling for the effect of the third faculty student performance. From the result obtained in this study, we conclude that there exists a strong negative resemblance between the performance of students in faculty of Physical sciences and faculty of Biosciences while controlling for the effect of student performance of faculty of Engineering for 100,000 permutations and using the Canonical distance which is “method three” in the “dist.quant (distance quantity)” function. R 2.13.0 programming package was used to run the analysis for 100,000 permutations.

Porting of Automotive Application on to Embedded Multicore Platform[ ]


In modern computer hardware, increase in processing capacity is gained by introducing more processor cores but not with increased clock speed. This may imply reduction in processing capabilities as far as the individual cores are concerned. So it is necessary to partially restructure the applications that are not designed to benefit from multiple cores for maintaining the existing performance. To improve the quality of experience for drivers as well as passengers, multi-core embedded systems are getting adopted on a very large scale in automotive industry. But measures and methodologies for porting applications are yet to be standardized. Solving the issues related to it will open up interesting avenues for utilization of multi-core systems in automotive industry. This work emphasizes on porting legacy automotive application onto embedded multicore platform for better performance.

Motion Artifact Reduction in fNIRS Signals by ARMA Modeling Based Kalman Filtering[ ]


Functional Near Infrared Spectroscopy (fNIRS) is a technique that is used for noninvasive measurement of the oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) concentrations in the brain tissue. Since the ratio of the concentration of these two agents is correlated with the neuronal activity, fNIRS can be used for the monitoring and quantifying the cortical activity. The portability of fNIRS makes it a good candidate for studies involving subject’s movement. The fNIRS measurements, however, are sensitive to artifacts generated by subject’s head motion. This makes fNIRS signals less effective in such applications. In this paper, the autoregressive moving average (ARMA) modeling of the fNIRS signal is used for state-space representation of the signal which is then fed to the Kalman filter for estimating the motionless signal. Results were compared to the autoregressive model (AR) based approach and showed that the ARMA models outperform AR models because of better modeling of the fNIRS signals. We showed that the signal to noise ratio (SNR) is about 3 dB higher for ARMA based method.

Design of Triple Effect Evaporator Developed By a Program in C++[ ]


The aim of this work is to develop a program in C++ software for the design of triple effect evaporator in forward feed mode with mechanical design. In this mechanical design a short tube vertical evaporator (STV), Calandria type has been used .The developed programme is then used for solving the non-linear equations for the evaporation system and the results obtained are finally compared with the problem given in Kern [1], Foust [2], and Dutta [3]. Evaporation ordinarily means vaporization of a liquid or that of a solvent from a solution. But in chemical engineering terminology, evaporation means removal of a part of the solvent from a solution of a non- volatile solute by vaporization. Where the objective of vaporization is to concentrate the solution. It is one of the most important operations in the process industries. Typical examples are concentration of sugar-cane juice in a sugar plant, concentration of an aqueous solution of ammonium sulphate in a fertilizer plant, concentration of dilute recycled sodium hydroxide in an alumina plant and many others. Evaporation differs from drying and distillation. In distillation the components of a solution are separated depending upon their distribution between vapour and liquid phases based on the difference of relative volatility of the substances. Whereas the removal of moisture from a substance in presence of a hot-gas stream to carry away the moisture leaving a solid residue as the product is generally called drying. Evaporation is normally stopped before the solute starts to precipitate in the operation of an evaporator.

MAHUA (MADHUCA INDICA) AS A SOURCE OF BIODIESEL IN INDIA[ ]


The Mahua trees are indigenous to India, grow even in draught prone areas and are found abundantly over several parts of India. If the seeds fallen are collected, and oil is extracted at village level expellers, few million tons of oil will be available for lighting lamps in rural area. In some countries, Mahua oil is considered edible as it is used only for preparing ghee, but in our country it has been considered as non-edible oil. Growing Mahua trees would also help in protecting the environment and benefit the farmers as well. It is the best substitute for kerosene. Since these are spread over a large area, collection of seeds for Biodiesel manufacture is not viable. A compact plantation can support a Biodiesel plant. The oil has not yet found any significant commercial application. But due to increase in awareness and growth in research in this area the Mahua can be developed as the alternative source of fuel by replacing diesel. In the present study attempt has been made to study the scope of Mahua in India.

Tele- Vehicle Insurance[ ]


Telematics is a branch of Information technology that deals with long distance transmission of data. The word telematics technically refers to any system by which a mechanical or electronic device communicates with other devices or with human users over a network. In case of vehicle telematics information about the vehicle such as its location, fuel level , speed , driving scenario etc will be transmitted over a distance. Here a major area of research is discussed where vehicle insurance is integrated with telematics. Vehicle insurance will be based on the way the driver drives. Driving behavior is monitored and communicated to the insurance provider. Based on this data insurance premium will be tabulated. Tele-vehicle insurance invokes safe driving habits, which in return reduces the number of accidents, reduces insurance premium etc. Insurance industry will soon be able to reap the benefits of Telematics.

CLASSIFICATION OF BRAIN ENCEPHALIC TISSUES FROM MRI IMAGES USING SPHERE SHAPED SUPPORT VECTOR MACHINE (SSSVM)[ ]


The boundary of each encephalic tissue, which makes up the brain, is highly irregular. So, traditional 3-D reconstruction algorithms, using brain MRI images do not give accurate reconstruction. Two class Support vector machines have been very successful in pattern recognition problems. Sphere-shaped support vector machines (SSSVMs) is applied in the 3-D reconstruction because of its powerful ability to solve nonlinearity problems. Image fusion technique is used to minimize information loss and then Region growing method is used for segmentation of MRI images as it gives accurate results and used to segment more than one type of brain tissue at a time. These segmented images are then classified using SSSVM. The selection of optimized parameters to make SSSVM more flexible is done using Immune Algorithm

DECISION MAKING TO SPEND AVAILABLE RESOURCES ON CONSUMPTION RELATED ITEMS[ ]


Every customer shows inclination towards particular products and services. Consumer interest is nothing but willingness of consumers to purchase products and services as per their taste, need and of course pocket. Marketing starts with the needs of the customer and ends with his satisfaction. It starts with the buying of goods. Management is the youngest of sciences and oldest of arts and consumer behavior in management is a very young discipline. Various scholars and academicians concentrated on it at a much later stage. It was during the 1950s, that marketing concept developed. The study is about how customers make decisions to spend their available resources time, money, effort on consumption related items and specially during buying footwear. It includes the study of why they buy, when they buy it, how often they buy it, and how often they use it.
