The Paleocene-Early Eocene Foraminiferal Biostratigraphy Of Eastern Dahomey Basin, Sw Nigeria [Full-Text] [References]Okosun, E. A. and Alkali, Y. B
The foraminiferal biostratigraphy of the Paleocene - early Eocene strata of SW Nigeria which represents the eastern Dahomey basin has been studied from four boreholes and two outcrops. A fairly diverse planktic and benthic foraminiferal assemblage was recovered.Six planktic biozones comprising Praemurica pseudobulloides, P. inconstans, Morozovella angulata, Globanomalina pseudomenardii, Morozovella velascoensis and M. subbotinae were identified. Two benthic concurrent range zones, Anomalinoides uboniferus - Eponides pseudoelevatus and Planulina oyae and Uvigerina hourcqi have been identified. These biozones will serve as useful correlation tools in the West African coastal and inland sedimentary basins.

Expression of NT-3 and BDNF in cerebro-spinal fluid of patients with Tuberculous meningitis [Full-Text] [References]Yun Li, Chun Peng, Zi-Hua Zhang, Xiao-Yan Zhang, Dan-Dan Li, Jian Zhong
Aim: To explore the expression of brain deriverd neurotrophic factors (BDNF) and neurotrophic factor-3 (NT-3) in the CSF of patients with Tuberculous meningitis (TBM). And elucidate the underlying mechanisms. Methodology: Prospective observational clinical study performed on 18 adults with TBM and 12 Adults with viral meningo-encephalitis (ME). 9 controls with non-in?ammatory intracranial hypertention were also employed. Neurotrophic factor levels in the CSF were measured using an immunoenzymatic assay(ELISA). Results: Both NT-3 and BDNF protein level of CSF were higher in patients with TBM at acute period than the patients with viral ME (P<0.05). Whereas there was no statistical difference of BDNF protein level between the patients with TBM and non-inflammation intracranial hypertention group(P>0.05). The patients with viral ME also showed no statistical differnce of BDNF protein level compared with non-inflammation intracranial hypertention group(P>0.05). NT-3 expression was higher in the patients with TBM than non-inflammation intracranial hypertention group(P<0.05). But the patients with viral ME showed no significant difference compared with non-inflammation intracranial hypertention group(P>0.05). Furthermore, NT-3 protein level in the CSF of patients with TBM at acute period was higher than BDNF protein level (P<0.05). Conclusion: The expression variations of NT-3 and BDNF protein level in CSF may re?ect an endogenous attempt at neuroprotection against biochemical and molecular changes during both TBM and viral ME at the acute period. Which suggested a marked and rapidly activated intracerebral neurotrophic factors biosynthesis after the patients subjected to TBM. The expression of NT-3 and BDNF is likely to play a neuro-immunomodulatory role in the process of TBM.

Land use land cover change detection of Ghatkesar mandal,RangaReddy district using Remote sensing and GIS[Full-Text] [References]Faridkhan,Dr.T.Vijayalakshmi,Dr.Santosh Kumar
Land use and land cover change has become a central component in current strategies for managing natural resources and monitoring environmental changes. Urban expansion has brought serious losses of agriculture land, vegetation land and water bodies. Urban sprawl is responsible for a variety of urban environmental issues like decreased air quality, increased runoff and subsequent flooding, increased local temperature, deterioration of water quality, etc. In this work we have taken Rangareddy District, Ghatkesar Mandal as case to study the urban expansion and land cover change that took place in a span of 05 years from 2006 to 2011. Remote sensing methodology is adopted to study the geographical land use changes occurred during the study period. Satellite Imagery- IRS1D, LISS-III+PAN FUSED of two different year are taken into consideration. After image pre-processing, un-supervised classification has been performed to classify the images in to different land use categories. Classification accuracy is also estimated using the field knowledge obtained from field surveys. Information on urban growth, land use and land cover change study is very useful to local government and urban planners for the betterment of future plans of sustainable development of the city.

A Study on Hubbert Peak for Natural Gas of Bangladesh: A System Dynamics Approach[Full-Text] [References]Saifullah Al Yusuf, Sabuj Das Gupta, Shuva Paul, Md. Shahinur Islam, Sudip Majumder
M. King Hubbert, an American geophysicist, in 1956 introduced a logistic equation for the estimation of USA peak and lifetime. As a case study, this paper investigates the Hubbert peak for Natural Gas production of Bangladesh. In this work, the authors have adopted system dynamics methodology to examine the Hubbert peak for Bangladesh's Gas production. Results show that the peak will occur in the 2012 with a value of 2184550 million cubic foot which is about 3 times of the 2011 year production. The proposed model helps us to evaluate different scenarios as well as performing sensitivity analysis which give us informative and useful forecasts about the time and value of Hubbert peak in different conditions. Thus, it is useful for Bangladeshi and international energy policy makers to understand the forthcoming shortage in the world's energy supply. Since this is the first study of Hubbert peak for Bangladesh, comparison with previous forecasts about this peak is not possible in this study.

Behavior of Integral Abutment Bridge with and without Soil Interaction[Full-Text] [References]R.Shreedhar, Vinod Hosur, Iftikar Chappu
Integral Abutment bridges (IAB's) can be defined as bridges without joints. The main purpose of constructing IAB's is to pre-vent the corrosion of the structure due to water seepage through joints. The biggest uncertainty in the design of these bridges is the reaction of the soil behind the abutments and next to the foundation piles, especially during thermal expansion. This lateral soil reaction is nonlinear and is a function of the magnitude and nature of the wall displacement.To gain a better understanding of the mechanism of load transfer due to thermal expansion, which is also dependent on the type of the soil adjacent to the abutment walls and piles, a 3D finite element analysis is carried out on representative IAB. In this paper two models are compared one with considering soil interaction and other without soil interaction and live load is applied using STAAD-Beava. The main objective is to study the trends in bending moment, shear force and deflection in central and end longitudinal girders and deck slab due to dead load, live load in combination of thermal loads. This paper emphysis that the temperature effects are more significant in case of integral abutment bridges, however the changes in soil properties behind the abutment and around the piles do not affect significantly the performance of super structure.

Methodology for EEG Based System Development to Detect Objective Pain in Human Body[Full-Text] [References]Asim Mahmood , Nasir Mahmood, Nazish Iqbal, Zainab Hafeez
Objective was to develop a system that makes difference between EEG patterns, to detect pain. Keeping in mind this phenomena the techniques were explored to develop such a system. Literature studies further cleared that acute pain signals moving from all part of human body to brain consists of certain frequencies bands between 0-98.4Hz. Further banding includes eight different bands in which different pains show their responses. Skin on the human skull is rough and it's bad conductor for getting signal out of it, thus skin is prepared by rubbing to remove dead cells, using a simple glass rod. After that EEG conductive paste is applied and skin is again rubbed to fill the porous surface of skull. Ag/AgCl electrodes with gold contacts are used for getting the signals. These are special purpose electrodes made for picking signals of very low voltage (µV) range. EEG gel is applied on the electrodes to make a better conductive contact between skin and electrode. The locations of the skull are decided by 'International 10-20 System for Electrode Placement'.

Blocking Misbehaving Users in Anonymizing Networks[Full-Text] [References]Rajkumar Rathod Banoth , Chandra chary sreeramoj, Dr. G. Narsimha
Internet services can be accessed privately through anonymizing networks like Tor. A set of routers are used to achieve this in order to hide the identity of client from server. The users of such networks often indulge into malicious activities and cause damage to popular web applications. The administrators of those web sites do block the IP address from which the request comes. This is not the practical solution as the hackers operate through anonymous networks. Blocking a node based on IP address will cause misbehaving and genuine users to lost access to the web sites. This is the problem in the existing systems and motivation to take up this research work. The proposed system develops a security mechanism that ensures that only the misbehaving users are blacklisted while genuine users and their anonymity are preserved. Even though the misbehaving users are blacklisted, their privacy is still maintained. The experiments revealed that the system is able to block misbehaving users only instead of blocking the node through IP address.

Improving Sound Quality by Bandwidth Extension[Full-Text] [References]M. Pradeepa, M.Tech, Assistant Professor
In recent telecommunications system uses a limited audio signal bandwidth of 300 to 3400 Hz. In recent times it has been proposed that the mobile phone networks with increased audio signal bandwidth of 50Hz-7 KHz will increase the sound quality of the speech signal. In this paper, a method extending the conventional narrow frequency band speech signals into a wideband speech signals for improved sound quality is proposed. A possible way to achieve an extension is to use an improved speech coder/decoder (CODEC) such as the Adaptive Multi Rate - Wide Band (AMR-WB). However, using an AMR-WB CODEC requires that both telephones at the ends of the communication link support it. Moreover the Mobile phones communicating with wire-line phone can therefore not utilize the enhanced feature of new CODECS; to overcome this limitation the received speech signal can be modified. The modification is meant to artificially increase the bandwidth of the speech signal. The proposed speech bandwidth extension method is Feature Mapped Speech Bandwidth Extension. This method maps each speech feature of the narrow-band signal to a similar feature of the high-band and lowband, which generates the wide band speech signal Y(n).

It has always been a challenging undertake to build a user friendly website and make it a useful resource for the audiences. User satisfaction is related to usability of a product. Here with this paper my effort is to develop a methodology in order to provide a recommendation and guidelines of whether a website meets usability requirement or not. The methodology aims towards an assessment of a website and prescribe a remedial to achieve more usability. I have developed a simple excel spreadsheet to demonstrate the methodology that I have developed. In order to prove the concept and the methodology, I have considered a website as a case. How to apply the methodology on the case website has been explained and the case website has been assessed applying the proposed methodology. In order to assess the website, at first stage, usability factors have been identified. The usability factors are the key components of the assessment process. During the assessment process, based on the websites usability quality and availability, every usability factor gets a weight. The total value (the sum) of all the weights is the usability value of the website. At the final stage of the assessment process the study shows total usability value of the case website. This paper will also explain and describe what usability means to the web users and why it is very essential to focus on usability perspective of a website. Comparision study between websites and remedial guidelines are not in the scope of this paper though the original research work includes both of thsese area based on the Assessment Methodology. This paper merely focusses to the fundamental research of developing a 'Assesment Methodology'.

A Review Report on Cryptovirology and Cryptography[Full-Text] [References]Shafiqul Abidin, Rajeev Kumar, Varun Tiwari
Cryptography has traditionally been used for defensive purposes. Ciphers defend against a passive eavesdropper. Public key infrastructures defend against an active adversary that mounts a man-in-the-middle attack. Digital signature algorithms defend against a forger. E-cash systems defend against a counterfeiter and a double-spender. Pseudorandom bit generators defend against a next-bit predictor, and so on. Crypto virology extends beyond finding protocol failures and design vulnerabilities. It is a forward engineering discipline that can be used for attacking rather than defending.

Radiation pattern optimization by Apicalis Ant algorithm for smart Array antennas[Full-Text] [References]Debbat F, Bendimerad F. T.
In modern mobile communications systems, both desired and interfering signals change their directions continuously. Therefore, a fast tracking system is needed to constantly track the users and then adapt the radiation pattern of the antenna to direct multiple narrow beams to desired users and nulls interfering sources. This paper proposes a smart array antenna system, which can improve performance by spatial filtering. Smart array antennas backed by strong signal processing algorithms are able to automatically change the beam pattern in accordance with the changing signal environment. The adaptation is achieved by multiplying the incoming signals with complex weights and then summing them together to obtain the desired radiation pattern. Adaptive array optimization is an NP-hard problem. In this paper, a technique based on the API (Pachycondyla Apicalis algorithm) is presented to solve this problem. Several illustrative examples of patterns with imposed single and multiple null directions are given to show the versatility of the present method.

Enhanced QoS in MANETs using Analysis of Routing Protocol[Full-Text] [References]K. Venkata Ramana, P.C. Devi and B. Chaithanya
Mobile Ad hoc Network (MANET), is a self-configuring infra structure less network of mobile devices Connected by wireless links. ad hoc is Latin and means "for this purpose". Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. QOS is defined as a set of service requirements to be met by the network while transporting a packet stream from source to destination. Intrinsic to the notion of QOS is an agreement or a guarantee by the network to provide a set of measurable pre-specified service attributesto the user in terms of delay, jitter, available bandwidth, packet loss, and so on. In this paper we are presenting two mobile ad-hoc routing protocols DSDV and AODV. Here the DSDV is a proactive protocol depending on routing tables which are maintained at each node. The AODV is a reactive protocol, which find a route to a destination on demand, whenever communication is needed. Considering the bandwidth, throughput and packet loss, in both DSDV and AODV routing protocols, DSDV is best suited for only smaller networks and AODV is suited for general Ad-hoc networks. br />

LPG flow rate, Oxygen flow rate, Height above burner (HAB) and Exposure time have been identified to generate different flame conditions based on varying one factor at a time (OFAT) approach. 2 - level 'full factorial' design model in "Minitab12" software has been used for design of experiments. The 16 samples of soot with different flame conditions were collected on the surface of stainless steel plate. The output parameters i.e. weight of soot and substrate surface temperature were analyzed by Analysis of variance (ANOVA) to ensure that the experimentation is following the physics of the diffusion flame. Transmission electron microscope (TEM) images showed the growth of well aligned single walled carbon nanotubed structures with high aspect ratio as 220 nm - 650 nm diameter and 534 nm - 1803 nm length. In the present study the parametric range for producing the single walled carbon - nanotubed structures through LPG diffusion flame were found and optimized.

Assessment on Ground Control Points in Unmanned Aerial System Image Processing for Slope Mapping Studies[Full-Text] [References]Khairul Nizam Tahar, Anuar Ahmad, Wan Abdul Aziz Wan Mohd Akib, Wan Mohd Naim Wan Mohd
The first objective of this study is to investigate the use of light weight rotary-wing UAV for mapping simulation model. The second objective is to determine the accuracy of the photogrammetric output produced from this study. In this study, the photogrammetric output such as stereomodel in three dimensional (3D), contour lines, digital elevation model (DEM) and orthophoto were produced from a simulation model with a dimension of 3m x 1m. In the simulation model, ground control points (GCP) and checked point (CP) were established using a total station. The GCP is used to produce photogrammetric output while the CP is used for accuracy assessment. A Nikon Coolpix consumer digital camera was used in image acquisition of the simulation model. Two methods of image capturing were used. In the first method, the camera was mounted vertically on a rotary-wing UAV and the images were captured at an altitude of 1.2 meters. In the second method, the camera was mounted vertically on a wooden structure at a fixed height (in this case 1.2 meters). After obtaining all the required images, they were then processed using digital photogrammetric software to produce photogrammetric output. Based on the results of this study, it was found that the final product of the rotary-wing UAV was not significantly different from the results acquired from the fixed height data acquisition method. The results of this study also showed that the differences of DEM and digital orthophoto between both methods were relatively small. Finally, it can be concluded that the UAV system can be used for small-scale mapping and other diversified applications, especially for small areas, which involves a limited budget and time constraints.

Analysis of Railway Wheel to study Thermal and Structural Behaviour[Full-Text] [References]Pramod Murali Mohan
Wheel-Rail systems are intensively subjected to damage caused by rolling contact and slip behaviour between the wheel and the rail. This is caused because of the brake block pushed against the wheel tread to create friction through which energy is dissipated. Friction also generates heat which results in distortion of the wheel as well as thermal stresses.In order to accurately predict this phenomena an accurate understanding of the thermal and structural loading on the wheel is required. In this paper this type of problem is being discussed. Two applications are presented. In the first the behaviour of wheel due to thermal and structural loading are dealt and in the second the combined loading is being discussed.

Nutrition education among adolescent girls on recipes using dehydrated vegetables -Am impact study of video and Booklet.[Full-Text] [References]Jaya Sinha, Kumar A.R, Yadav N, Pravin K, Tripathi U
Nutrition education has been defined as educational measures for inducing desirable behavioural changes for the ultimate improvement in the nutritional status of all nutrition intervention programmes. The importance of nutrition education as a means for improving the health and nutrition of community in the developing countries, has been increasingly realized during recent years. Lack of knowledge of the dietary requirements and the nutritive value of different foods is the main contributory cause for the widespread occurrence of many disease in developing countries. Nutrition education, which is practical and adopted to suit the socioeconomic conditions, food habits and local food resources, can tackle the problem to a great extent. Adolescent are one of the most important groups of any society because they have an influential effect of the future social economic and cultural status of society. Nutritionally, this age is very vulnerable because of double demand of growth and activity. So there is need to promote nutrition education. Micronutrient deficiencies like anaemia are important nutritional disorder among adolescent girls in Indian and other developing countries. Vegetables particularly the leafy ones,are known to be rich in these nutrients. Through produce in plenty when in season, their high perishability make their usage limited round the year. Dehydration or vegetables, one of the most popular and oldest method of preservation, is one of the important way to make the vegetables available in all seasons, thus supplying the important nutrient to our population group regularly. As mineral content is not lost during dehydration, dehydrated vegetables can be utilized to enrich the various conventional food products.

A New Procedure For Designing Single Sampling Plan Indexed Through Trignometric Ratios[Full-Text] [References]P.R DIVYA
Acceptance Sampling is the methodology which deals with procedures through which decisions to accept or reject of a lot which are based on the result of inspection of samples. The foundation of the scheme of acceptance sampling has laid by Dodge and Romig (1959). General procedures and necessary tables are provided for the selection of single sampling plan through tangent angle as proposed by Norman Bush (1953). Mandelson (1962) has explained the desirability for developing a system of sampling plans indexed through MAPD. Mayer (1967) has explained that the quality standard that the MAPD can be considered as a quality level with other conditions to specify the OC curve. Soundararajan (1975) has constructed tables for selection of single sampling plan indexed through MAPD and K (pT/p*) Suresh and Ramkumar (1996) have studied the selection of single sampling plan indexed through Maximum Allowable Average Outgoing Quality (MAAOQ) and MAPD.

A Comparative Study Of Reactive Routing Protocols In Mobile Ad Hoc Networks[Full-Text] [References]K. VENKATA RAMANA, M.Tech, K.Muniramaiah ,MCA and 2S. HEMASRI
Mobile Ad hoc networks (MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad hoc network is not a new one, having been around in various forms for over 20 years. The goal of the routing protocol is to have an efficient route establishment between a pair of nodes. Routing protocols used in wired network cannot be used for mobile ad-hoc networks because of node mobility .Many routing protocols such as proactive, reactive and hybrid. Reactive routing protocols have been found to be user friendly and efficient when compared to other routing protocols. The main boon of routing protocols when compared with proactive and Hybrid routing protocols is the relatively unconditional low storage requirements, higher mobility and the availability of routes when needed. There are a variety of reactive routing protocols suchasAODV,DSR,LAR1,LMR,ABR,SSI,TORA,RDMAR,MSR,AOMDV,MRAODV,ARA.However there is no study done over the efficiency of any reactive routing protocols. In this study a comparison and performance evaluation of two reactive routing protocols AODV and DSR are done using OPNET simulator to identify the protocol that is best suited for MANET'S

Multiple Mobile Agents In Wireless Sensor Networks Using Genetic Algorithm[Full-Text] [References]LingaRaj.K, Aradhana.D, Nagaveni.B.Biradar
It has been proven recently that using Mobile Agent (MA) in wireless sensor networks (WSNs) can drastically help to obtain the flexibility of application-aware deployment. Normally, in any MA based sensor network, it is an important research issue to find out an optimal itinerary for the MA in order to achieve efficient and effective data collection from multiple sensory data source nodes. In this paper, we firstly investigate a number of conventional single MA itinerary planning based schemes, and then indicate some shortcomings of these schemes, since only one MA is used by them. Having these investigations and analysis, a novel genetic algorithm based multiple MAs itinerary planning (GA-MIP) scheme is proposed to address the shortcomings of large latency and global unbalancing of using single MA, and its effectiveness is proved by conducting the extensive experiments in professional environment.

Implementation of FFT Algorithm for OFDM Wireless LANs[Full-Text] [References]Katta. Mangarao, Sirigineedi.Srividya
The explosive growth of 802.11-based wireless LANs has attracted interest in providing higher data rates and greater system capacities. Among the IEEE 802.11 standards, the 802.11a standard based on OFDM (Orthogonal Frequency Division Multiplexing) modulation scheme can be defined to address high-speed and large-system-capacity challenges. Although DSPs have been used to implement the 802.11a standard, they can only support limited data rates due to the lack of global parallelism found at the application level. Hence, it is still a major challenge to develop a software implementation for the 802.11a standard on a DSP to meet the high-data-date requirements.

Dielectric Diagnosis of EHV current Transformer Using Frequency Domain Spectroscopy (FDS) & Polarization and Depolarization Current (PDC) Techniques[Full-Text] [References]Abhishek Joshi, Pooja Aaradhi
Current transformers (CT) are an important element of substation used for metering and protection. The CT forms main link in ensuring the reliability of the entire power system. Most of the faults occurring in Instrument transformers are due to insulation failure (Viz. oil and paper for this research work). Various factors responsible for degradation and failure of insulation in CT are electrical, mechanical and thermal stresses, poor maintenance and incorrect loading. The CTs used in substations should be replaced in order to ensure continuity in the power supply for the end user. For a systematic replacement program to be planned and to avoid unexpected breakdowns in Instrument transformers, dielectric diagnostic tools are gaining high importance. These dielectric diagnostic tools deduce the moisture in paper or pressboard and oil conductivity from dielectric properties like return voltage, charging currents and dissipation factor. Two dielectric response measurement techniques have been established; the current measurement in the time domain, also called the Polarization and Depolarization Current (PDC) and the Frequency Domain Spectroscopy (FDS) techniques. The research considers an application of this technique to 245kV and 420kV OIP CTs. The application of FDS and PDC techniques for CT insulation analysis and its effectiveness to on field applications is also discussed.

Student's Examination Result Mining: A Predictive Approach[Full-Text] [References]Vaneet Kumar, Dr. Vinod Sharma
This paper takes into consideration the various factors and their influence on student performance in education and predicts their final examination result whether Pass or Re-appear. Various factors such as previous year results, attendance, financial status of family, parent educational qualification, internet use for study material, parents visits to school, extra classes etc plays an important role in students' education. A lot of other immeasurable factors such as student motivation level, learning techniques used, strategy for preparing for final examination, student behavior and habits, questions chosen for answering and way of expressing ideas may also be responsible for the final result, but they are beyond the scope of this paper. This paper discusses the most common measurable factors among the students. The data mining methodology while extracting useful, valid patterns from education database environment contribute to proactively ensuring students maximize their academic output [1]. The results of this paper present an idea about these factors and their influence on student performance and may also be used by the educational administrators in making proper decisions for the welfare of the students. Naive Bayes classifier is applied to calculate probabilities. MATLAB is used to get the final outcome which helps in predicting final examination results. The data set is collected from different schools by distributing questionnaires, has been used as input to the algorithm.

Energy Efficient Technology Diffusion Factors: A Systematic Review [Full-Text] [References]Suchismita Bhattacharjee, Andrew P. McCoy
Due to the escalating population and the resulting increase in energy use, the world is faced with the challenge of energy crisis. To mitigate the rise in energy crisis, innovation, adoption, and diffusion of energy efficient technologies is imperative. Review of available literatures indicates that expected improvement in energy consumption has not been achieved in spite of the innovation and improvement in energy efficient technologies. This imbalance points towards the lack of proper adoption and diffusion of these technologies. This paper has looked into prior arts to determine the factors responsible for this diffusion process. Upon identifying the factors, it is evident that some factors can be improved to act as accelerators to the diffusion process. The other set of factors tend to remain as hindrances which can be reduced to an extent, but not removed completely. The paper further investigates the reasons behind these factors and categorizes them under three groups - financial, informational, and behavioral. Findings prove that most of the factors can be attached to a financial cause. Thus research and development alone is not the answer to the rising energy demand, but effective economic motivation is necessary to curb the demand. Future research will look into the present energy policies and group them based on their targeted sector. This will enable to locate the gaps in the policies already implemented and subsequently help in the creation of new policies.

Intelligent Belt for the Blind[Full-Text] [References]Sneha Venkateswar, Ninad Mehendale
This system focuses on the Electronic Blind Mobility Aid that helps blind people to travel autonomously using sensors mounted on a belt to be worn around the waist.Many people with visual impairments can travel independently with this advanced technology. Blind people cannot always travel alone due to the various obstacles that come in their path. A blind belt can be used to extend the user's range of sensation. It is usually worn around the waist as an obstacle detector.It is well known that visually impaired people use their hearing sense to compensate for their reduced eyesight. For instance, they can recognize sound sources. This project helps blind people travel alone by using sensors mounted on a belt to be worn around the waist. Thus they can be forewarned about obstacles with the help of the headphones and speakers. This will allow them to benefit from a systemthat they can use every day and hence making the blind person independent, while being able to identify potential risks, obstacles and routes.

The Formation of the High Tc Phase of Melt Quenched Bi1.6Pb0.4Sr2Ca2Cu3Oy[Full-Text] [References]Shirley T. Palisoc, Michelle T. Natividad, Phebe P. Mendoza
The melt quench method was applied in the fabrication of Bi1.6Pb0.4Sr2Ca2Cu3Oy superconducting ceramics. The effects of melting the lead doped BSCCO were investigated using the scanning electron microscope and energy dispersive spectroscope (SEM/EDAX), differential thermal analyzer (DTA), x-ray diffractrometer (XRD) and magnetic susceptibility (?-T) analyses. The results showed that the superconducting phase appeared even in the precursor samples. Glass forming tendency is also remarkably retarded. Sintering at 840°C for 24 hours completely vanished this glass forming ability. The critical temperature (Tc) onset was strongly dependent on the amount of non-superconducting impurities, grain size and intensity of the endothermic peak that affects the phase formation in the partially melted state.
