A Novel Framework for Image Search in Social Networking

: Most Internet users, you probably spend a decent amount of time using a search engine to find content and answers. Social network search engines are designed to do Search they can filter out all the unnecessary results we might get if we used a regular search engine. The large-scale user-generated meta-data not only facilitate users in sharing and organizing multimedia content, but provide useful information to improve media retrieval and management. Personalized search serves as one of such examples where the web search experience is improved by generating the returned list according to the modified user search intents. In this paper, we propose a novel framework simultaneously considering the user and query relevance to learn to personalized image search. The proposed framework contains two components: one is a Ranking based model and another one is User-specific modeling to map the query relevance and user preference. We did experiments on large scale data to demonstrate the effectiveness of the proposed method. In this paper we consider the simple case of one word-based query. As well as topic based.
BER Enhancement of CDMA system using Broadside Antenna array and SDMA in Rayleigh Fading Channel environment

– Code Division Multiple Accesses (CDMA), one of the effective and efficient technologies, is used in 2nd generation (2G), 3rd generation (3G) wireless and becomes one of potential candidates for the physical layer of 4G mobile systems with the aim of improving cell capacity communication. The paper presents the CDMA system with Broadside antenna array is proposed for a multipath fading channel. The performance is evaluated in terms of bit error probability (BER) for the DS/CDMA system environment with QPSK modulation is use in the Rake Receiver with coding technique. The Standard Gaussian Approximation (SGA) is used to evaluate the performance of coding and Rake Receiver over a frequency selective Rayleigh fading channel with antenna array is estimated. From the analytic to Rayleigh fading results, the performance is evaluated for CDMA systems on additive white Gaussian noise (AWGN) and a multipath fading channel. Analytical expression of the BER is derived, including the effects of the spatial correlation be-tween antenna elements and non-identical fading for different multipath. In the receiver, dispreading and demodulated, coding, Rake Receiver, directive antenna (Broadside array antenna) are employed to improve the system performance. We examined the BER performance of Rake Receiver with, varying the number of users, spreading factor, Rake fingers, Interfering Cells, and the value of directivity of antenna at base Station (number of antenna). Antenna arrays are majorly used: Broadside array and End fire array. They are used to radiate their own beam patterns. The antenna arrays with different arrangements: The Spacing of the elements and the Number of elements may produce the diverse radiation properties. The overall radiation pattern results in certain directivity and different lobes with different number of elements and different spacing between them.

ACOUSTIC ECHO CANCELLATION AND DENOISING USING ADAPTIVE FILTER AND DWT

This paper presents a robust acoustic echo cancellation(RAEC) using adaptive filter in the Short Time Fourier transform(STFT) domain and de-noising the near end and far end signal from the conference using Discrete wavelet Transform (DWT). The STFT domain is a simple compared to the traditional frequency domain for cancellation of robust acoustic echo, because frequency domain requires several applications of the Discrete Fourier Transform(DFT) and inverse DFT, while the RAEC allows for continuous and stable filter updates during double talk without freezing the adaptive filter. In this work we combining the de-noising of the signal and acoustic echo cancellation. Experimental results improved the performance of the echo reduction and the predicted sound quality.
The Level of Knowledge of Dietitians About Dietary Management of Children with Food Allergy

Objective: The aim of this study was to evaluate the knowledge of dietitians and dietetic students about food allergy in order to develop suggestions for educational activities. Materials and Methods: Dietitians and dietetics students were surveyed via a questionnaire aimed to document their knowledge about food allergy management. Results: Of the 150 questionnaires distributed, 122 valid questionnaires were returned. The response rate was 81.3%. Of all the respondents, 51.4% were working in a hospital. About sixty percent of respondents rated themselves ‘moderate’ for identifying some clinical manifestations of FA, developing elimination diets, providing avoidance education, managing the dietary needs of children with cows’ milk allergy (CMA). Only 72.1% of respondents answered the questions about foods that can cause anaphylaxis correctly. About forty percent of respondents did not recognize that food allergens could be transmitted by means of tools used for service such as knives and spoons and thought that smoke of the cooking food does not cause allergy. About sixty percent of respondents also thought that touching the food never causes allergic reactions. Of all the respondents, only about 18.9% suggested amino acid based formulas for children with CMA, 23% suggested fully hydrolized formulas and 39.3% thought that lactose free formulas can be given to patients with CMA. Conclusion: This study revealed that there are some gaps in the knowledge of dietitians about food allergy. Dietitians should be given training on this subject and there should be a re-evaluation of health policies with a wider global perspective.
Gravitational Optimization Using Fuzzy C-Means Clustering Algorithm

: Nowadays the growth of spatial data encountered in different application domains and their analysis has become more important. Clustering is one of the important tasks in spatial data mining. Spatial clustering aims group similar spatial objects into group or clusters so that objects within a cluster have high similarity in comparison to one another but are dissimilar to objects in other clusters. In this paper, we propose a new approach for data clustering. Initially the proposed approach exploits spatial fuzzy c-means for clustering the vertex into homogeneous regions, Fuzzy c-Means Clustering performs clustering by iteratively searching for a set of fuzzy clusters and the associated cluster centres that represent the structure of the data as best as possible. In order to improve the performance of fuzzy c-means to cope with segmentation problems, we employ gravitational search algorithm which is inspired by Newton’s rule of gravity. The improved GSA (namely Fuzzy-GSA) is employed to construct a novel data mining algorithm for classification rule discovery from reference data sets. Gravitational search algorithm is incorporated into fuzzy c-means to take advantage of its ability to find optimum cluster centres which minimizes the fitness function of fuzzy c-means.
Software Quality Assessment in Object Based Architecture

Software metrics are required to measure quality in terms of software performance and reliability related characteristics like dependencies, coupling and cohesion etc. It provides a way to measure the progress of code during development and having direct relationship with cost and time incurred in the software design and development at their later stages. These major issues must be checked and informed early in the development stage, so that reliability of any software product could be ensured for any large and complex software project. Object oriented software metrics directly focuses on the issues like complexity, reliability and robustness of the software developed using object oriented design methodologies. It reflects the time, cost and effort that Functionality, Scalability, Usability, Performance, Reliability, maintainability. Durability, Serviceability, Availability, Installability, Structured ness and Efficiency. There are two types of parameters namely functional parameters and nonfunctional parameters. Functional parameters deal with the functionality or functional aspects of the application while non functional parameters deal with the non-functional parameters (but desirable) like usability, maintainability that a developer usually doesn’t think of at the time of development oriented software like Extensibility, Reusability, efforts, manageability and cost [1, 2, 3]. To know more about the internal structure of the product one should know more about the interdependencies of parameters of metrics and Software quality parameters. Figure 1 shows the interdependencies of the metrics parameters and software quality parameters by measuring Object Oriented Metrics.

Topological solitons in an DNA molecule spin chain

It is now well known that DNA can be regarded as a physical elastic object in a viscous environment. Two strands of double helix are antiparallel and two polynucleotide chains are coiled about the same axis such that B-DNA (Z-DNA) has right-handed (left -handed) helical sense. The existence of super coiled DNA has been confirmed in experiments long ago and it was found that in vivo chromosomal DNA molecules contain topological domains along which super coiling canoccue.1−3 DNA molecules from prokaryotes (cells without nuclear membranes) oft en adopt the interwound structures which are called plectonemic” super coils. In eukaryotes (cells with nuclei and other organelles with their own internal membranes) chromosomal DNA molecules are also known to be organized into topological independent loops.2−5 Statistical mechanics of super coiled DNA has been studied by several authors.6

Impact of Cement Dust Deposition on Plants in the Vicinity of Ashaka Cement Factory, Gombe State, Nigeria

Impact of Cement dust deposition on plants around the vicinity of Ashaka Cement was carried out. The idea behind the study was to determine to what extent plants, especially spinach, baobab leaves and millet that are so abundant around the factory and mostly consume by the people of the area were contaminated by dust emanating from the factory. Different directions of the wind at different times of the year were considered so that all the plants around the vicinity of the factory were effectively covered. Levels of pollutants were determined which indicated to what extent the plants were safe or otherwise for consumption. The elemental composition, distribution and some physicochemical aspects of plants in the vicinity of Ashaka cement factory were scrutinized. The pollution load and its impact on the environment were assessed with some new techniques such as high-resolution energy dispersive X-ray fluorescence (EDXRF) spectrophotometer. The facility was integrated with computer system capable of determination of elemental composition of samples and some physiochemical aspects in form of their oxides. Other instruments used were flame atomic absorption spectrophotometer (AAS), UV-visible spectrophotometer and flame emission spectrophotometer (FES). The X-ray fluorescence techniques was used to determine elemental composition of solid plant samples was used as pollution tracers, and these indicated a radial distribution along the wind directions. All the heavy metals also indicated similar trends. Although levels of some elements were low in some areas, the mean concentration of most of the components were 2 – 10 folds greater in order of magnitudes than the levels expected in unpolluted soil and sediments. There was a reasonable comparison of elemental concentration in plants with those found in most soils. Comparison of cement dust components and those deposited on plants depict positive correlation. The relative comparison of concentrations of heavy metals in plants follow the sequence : Mn>Pb>Cu>Zn.
QUALITY OF SERVICE IN NETWORK ADMINISTRATIONS

: Today’s computer networks have gone from typically being a small local area network, to wide area networks, where users and servers are interconnected with each other from all over the world. This development has gradually expanded as bandwidth has become higher and cheaper.But when dealing with the network traffic, bandwidth is only one of the important properties. Delay, jitter and reliability are also important properties for the quality of network connection. This is because different applications has different needs, and therefore require different properties from the network. System administrators are in an increasing degree involved with the troubleshooting of solving network problems concerning the quality of service for the different applications.This research paper analyzed techniques for measuring, analyzing, presenting and interpreting the different properties for the administration of remote computer network.
From the foregoing, the recognition of the importance of physics education in Nigeria’s educational system and for the nation’s technological development gives a picture of the high expectation of students

The study sought to determine the effect of Multiple Intelligences Development Approach (MIDA) on students’ interest and achievement in physics. Two research hypotheses guided the study. The design adopted was a quasi-experimental, non-randomized control group pre-test-post-test design involving two groups (experimental and control). The sample comprised 100 senior secondary two (SS2) physics students in six intact classes from six secondary schools in Ukanafun Local Government Area of Akwa Ibom State selected through purposive sampling technique. In each of the six schools, a random stream was chosen. Three streams in the chosen schools were then randomly assigned to the experimental group and the control group respectively. Two instruments namely: the Haussler and Hoffman Interest Scale in Physics (HHISP) and the Achievement Test in Physics (ATP) were used in collecting the pertinent data. The experimental group was taught sound concepts in physics using the MIDA while the control group was taught the same concept using the conventional (expository) approach. The students were exposed to treatment for four weeks. Data generated were analyzed using the Analysis of Covariance (ANCOVA) and decision made at 0.05 level of significance. The results indicated that the MIDA was significantly more effective in promoting students’ interest and achievement in physics over the conventional approach. Based on these findings, conclusions are drawn and implications for educational practice suggested. Some recommendations were made, among which was that the use of MIDA should be encouraged in the teaching and learning of physics at the senior secondary school level.
ARTIFICIAL NEURAL NETWORK AIDED RETINA BASED ARTIFICIAL NEURAL NETWORK AIDED RETINA BASED BIOMETRIC IDENTIFICATION SYSTEM BIOMETRIC IDENTIFICATION SYSTEM

- Artificial Neural Network (ANN)s are efficient means of prediction, optimization and recognition. Retina is a unique biometric pattern that can be used as a part of a verification system. An ANN can be configured and trained to handle such variations observed in the texture of the retina. The specialty of the work is associated with the fact that if the ANN is configured properly it can tackle the variations in the retinal images and that way provides the insights for developing a system which requires the samples for verification and authorization. A system designed to provide authentication decision using the input can be a reliable means of verification. Such a system designed using ANN and using retina input is described here. Experimental results show that the system is reliable enough for considering it as a part of a verification mechanism.
An Optimal Beacon Selection Technique for Time Synchronization in Underwater Acoustic Wireless Sensor Networks

: Recently, Underwater Acoustic Sensor Networks (UASNs) have been developed as a significant research area since it is marked that a huge amount of unexploited resources lies under water which covers about 70% of the Earth. UASN is an effective combination of wireless, acoustic and sensor technology having the capabilities of smart sensing, intelligent computing and communication. In UASNs, the time associated with the sensed data is very critical for further data processing, which makes the time synchronization in UASNs as an essential requirement for many applications. Regrettably, GPS signaling cannot be used for underwater scenarios which pave the necessity to develop alternative synchronization approaches in UASNs. Beacon based synchronization approaches have been emerged as an efficient technique in UASNs, but in order to enhance the accuracy of such methods, the selection of an Optimal Beacon set is needed. In this paper, we are proposing an Optimal Beacon Selection Technique (OBST) for achieving accurate clock synchronization in UASNs. In our approach, a mobile AUV guided by a pre-defined trajectory will be used to generate a set of Virtual Beacons (VBs). The proposed beacon selection method addresses the physical, data link and network layer issues by selecting optimal beacon based on the Received Signal Strength (RSS) values from VBs, distance of separation from target node to be synchronized, residual energy and the received time stamps. An analytical model for optimal beacon selection was derived and analyzed based on the synchronization error and percentage of synchronization for dense and sparse networks. From the simulation results, it is found that the proposed optimal beacon selection technique outperforms the existing approaches in terms of synchronization accuracy, network cost and communication overhead.

ROBUST SPIHT CODED VIDEO TRANSMISSION OVER WIRELESS CHANNELS

There is a huge demand of video based services over internet and wireless networks, however, transmission of coded video bitstream over wireless channel is very challenging task. Various schemes have been proposed in the literature to combat the effect of transmission errors. In this paper joint source channel coding (JSCC) scheme is utilized to transmit the SPIHT (set partitioning in hierarchical tree) based Hybrid video coded bitstream such that the channel resources are efficiently utilized. The SPIHT is a bit-plane algorithm that generates embedded bitstream. The embedded bitstream and forward error correction (FEC) codes are exploited to form JSCC that minimize the effect of channel errors. The strength of the scheme is that the quality of the reconstructed video is improved without increasing the transmission bandwidth. Simulation results show that the proposed scheme gives up to approximately 25 dB of improvement over the system which does not incorporates FEC.
