Decision Level Fusion Based Multimodal Biometric System

—Systems that use unimodal biometrics tend to have less accuracy, variations that are due to intra class, restricted degree of freedom, non-universality, error rates that are not acceptable, etc. Based on these reasons, in the near past, most of the researchers have been concentrating on multimodal biometrics. Multimodal biometrics integrates various types of biometrics which outperform unimodal biometric systems. In this paper, it is proposed to combine Iris and Fingerprint biometric systems and try to exploit the use of such combination. Different features viz., texture, local binary pattern, are extracted from Iris and Fingerprint images of each class and combined to form the final feature vector. Various fusion techniques exist and in this work we concentrate on fusing the classifier results and then make an efficient decision out of that fusion. Results show that the proposed technique is outperformed existing techniques and an accuracy of 99% is achieved .
Evaluation of Factors Influencing Breastfeeding in Children Aged 0 to 24 Months Received in an Urban Community Health Center in Abidjan Cocody (Cote d'Ivoire)

Purpose: The aim of this study is to evaluate the factors influencing breastfeeding among children aged 0 to 6 months received in an urban community health center in Abidjan Cocody (Côte d'Ivoire). Methods: To do this, a cross-sectional and analytical study was conducted in the Anono Urban Community Health Service with 362 mothers interviewed using survey cards. The socio-economic characteristics, the choice of breastfeeding, the type of breastfeeding influencing breastfeeding were studied. The study ran from March to April 2018. The data was processed using Excel 2007. Results: The results showed that some factors hinder exclusive breastfeeding. Mothers' function was an impediment to exclusive breastfeeding, 43.93% were civil servants and 29.56% were students and 26.51% were housewives or shopkeepers. In our study, more than 40% of mothers did not practice exclusive breastfeeding for a cosmetic problem, 31% were related to the sex of the baby, 15% associated with caesarean delivery, 11% for low education level and 2.5% because of the age of the mother. Among the civil servant mothers, or students, 100% practiced mixed breastfeeding. Overall (362) of the mothers surveyed, over 54% practiced mixed breastfeeding. The majority of these mothers introduced water (52%), fruit juice (24%), cereals (15%) and herbal teas at 9%. More than 47% were unable to practice exclusive breastfeeding for the first six months. In this study there is a problem of satiety at 25.41%, insufficient milk secretion 19.34% and other conditions contraindicated for exclusive breastfeeding. Conclusion: The factors of the non-practice of exclusive breastfeeding were low education level, function, early introduction of solid foods, aesthetic problem, and unavailability of time of mothers, satiety problem, insufficient milk secretion and conditions for breastfeeding. These factors will have to be taken into account in the strategy to increase the rate of exclusive breastfeeding and its continuation up to six months in mothers in communes where the standard of living is relatively high.

Cross-Layer System for Cluster Based Data Access in MANET’S

- The objective of cooperative caching is to improve data availability, improve access efficiency and reduce query delay in mobile Ad-Hoc networks. Many types of cache replacement algorithms like LRU, LFU, LFRU, LRU-MIN and LFU-MIN are used to improve data accessibility and reduce query delay in cluster based cooperative caching in Mobile Ad-Hoc networks. But they have some limitations such as accessing remote information station via multi hop communication leads to longer query latency and causes high energy consumption, many clients frequently access the database server they cause a high load on the server and reduce the server response time . Multi hop communication causes the network capacity degrades when network partition occurs. The Research Paper gives an overview of Cooperative Cache Management Techniques and caching policies and propose a new algorithm can be regarded as a LRFU-MIN (least recently frequently used information with minimal number of page replacements). It discover a data source which induces less communication cost of moving cache blocks into the most recently frequently used position and minimizes caching duplications between neighbour nodes. In this paper we utilize a cross-layer design approach to improve the performance of combined cooperative caching and prefetching schemes. The paper examines the performance using NS-2 simulation environments. The proposed LRFU-MIN enhances the performance of cross-layer cluster based cooperative caching in mobile Ad-Hoc networks when compared with LRU and LFU-MIN.
Digital Image Watermarking: A Review

— Digital watermarking of multimedia content has become a very active research area over the last several years. Watermarking is a very important field for copyrights of various electronic documents and media. With images widely available on the Internet, it may sometimes be desirable to use watermarks. Digital watermarking is the processing of combined information into a digital signal. A watermark is a secondary image, which is overlaid on the host image, and provides a means of protecting the image. It acts as a digital signature, giving the image a sense of ownership or authenticity. Digital watermarking technique is very impressive for image authentication or protection for attacks. In this paper we aim to present a survey on different types of digital watermarks and methods to do image watermarking. Problems and challenges to produce watermarked images are also analyzed and reported. given in the document for the papers to be published.

Power Control with MIDRS Codes in VMIMO WSN Using Game Theoretic Approach

— Improvements in electronic and computer technologies have tiled the path for explosion of wireless sensor networks (WSN). A fundamental component of resource management in WSN is transmitter power control and an efficient power control technique is essential to support system quality and efficiency. The data transmitted from the sensor nodes is highly susceptible to error in a wireless environment which increases the transmit power. Error control coding (ECC) schemes can improve the system performance and has an impact on energy consumption. Further the adverse impacts caused by radio irregularities and fading increases the energy consumption and thereby reduces the WSN lifetime. To reduce the fading effects in wireless channel, multi-input multi-output (MIMO) scheme is utilised for sensor network. This paper proposes a power control solution considering Multivariate Interpolation Decoding RS (MIDRS) Code in Virtual MIMO (VMIMO) WSN using game theoretic approach. The game is formulated as a utility maximizing distributed power control game while considering the pricing function. VMIMO utilising space time block code (STBC) along with MIDRS code enables to achieve higher energy savings and longer network lifetime by allowing nodes to transmit and receive information jointly. The performance of the proposed power control scheme with MIDRS code for the virtual MIMO wireless sensor network is evaluated in terms of utility, power efficiency, energy consumption and network lifetime.

ILLUMINATION CORRECTION ON FACE IMAGE

- Many digital images suffer from poor illumination at the peripheries, often attributable to factors related to the light path between the camera and the microscope. So blur image will be found. A commonly used method for correcting this has been to use the illumination of an empty field as a correction filter (white shading correction). Different lighting condition affects the outputs. So it will become necessary to correct them to get appropriate output. In this paper we used RGB image and convert into HSI. Then perform HSI based color image equalization process using Iterative nth Root and nth Power. The iterative proposed method for equalization is based on achieving a normalized image with mean of 0.5 in R, G and B channels.
International Journal of Advanced Research in Computer Science and Software Engineering

— The purpose of this research paper is to define a critical step in studying the statistics of fingerprint minutiae to reliably extract minutiae from fingerprint images. Thus, it is necessary to employ image enhancement techniques prior to minutiae extraction to obtain a more reliable estimate of minutiae locations. Fingerprint Image enhancement is to make the image clearer for easy further operations. Since the fingerprint images obtained from sensors are not assured with perfect quality, various enhancement methods, for increasing the contrast between ridges and furrows and for connecting the false broken points of ridges due to insufficient level of ink, are very useful for keeping a higher accuracy to fingerprint recognition.

Real Time Detection of Odd Behavior and Irrelevant Promotion in Video Sharing Systems

: — Metacafe is one of the most popular video sharing system among all online video sharing systems, these video sharing systems provide features that allow users to post a video as a response to the topic that is being discussed. There are opportunities for its users to introduce polluted content, or simply pollution, into the system because of these features. For example, spammers may post an unrelated video as response to a popular one, aiming at increasing the likelihood of the response being viewed by a larger number of users in the same way also content promoters may try to gain visibility to a specific video by posting a large number of responses for boosting the rank of the responded video so that it will appear in the top lists maintained by the system. Content pollution means the posting of irrelevant content may jeopardize the trust of users on the video sharing system, thus in turn it compromises the success in promoting social interactions. In spite of that, the available literature is very limited in providing a deep understanding of this problem. In this paper, we address the issue of detecting video spammers and promoters considering you tube video sharing system.
Socio-Demographic Factors Associated with Advanced Stage of Cervical Cancer at Diagnosis in Kenyatta National Hospital, Kenya: A Cross Sectional Study

Background: Cervical cancer is the most common and leading cause of deaths due to cancer among women in Kenya. Early detection is necessary for initiation of treatments to prevent deaths. Identification of factors that contribute to advanced stage of cervical cancer is the first step towards early detection. Objectives: To determine socio-demographic factors associated with advanced stage of cervical cancer at diagnosis in Kenyatta National Hospital. Materials and methods:A cross-sectional study of 152 women with a histological proven cervical cancer was conducted at Kenyatta National Hospital. The women were selected using random sampling method. Information on demographic characteristics and stage of cervical cancer were abstracted retrospectively by auditing patients’ records from January 2014 to June 2014. Stages I and II were classified as ‘early stage’ and stages III and IV as ‘advanced stage’. Chi-square test (p-value<0.05) was used to determine association between advanced stage of cervical cancer and socio-demographic characteristics. Multiple logistic regression analysis was performed to determine the independent factors associated with advanced stage of cervical cancer at diagnosis. Results: Out of 152 patients with cervical cancer, 53.9% had advanced stage of cancer at diagnosis. Following multiple logistic regression analysis, the following factors were independently associated with advanced stage of cervical cancer: older age (50 to 75 years) (AOR=4.25; 95% CI=1.08-16.75; P=0.039), being single (AOR=2.28; 95% CI=1.03-5.06; P=0.043), never attended school (AOR=5.91; 95% CI=1.96-17.78; P=0.002), attended primary school (AOR=4.13; 95% CI=1.60-10.63; P=0.003) and HIV positive women (AOR=2.86; 95% CI=1.25-6.59; P=0.013). Conclusion:More than half of the patients presented with advanced stage of cervical cancer at diagnosis. None/low level of education, old age, being single and HIV infection were associated with advanced stage of cancer at diagnosis. Regular cervical cancer screening targeting these women could reduce advanced stage of cervical cancer at diagnosis.
Spectral Re-Evaluation Of The Magnetic Basement Depth Over Parts Of Middle Benue Trough Nigeria Using HRAM

The new high resolution aeromagnetic data have been used to re-evaluate parts of the Middle Benue Trough Nigeria using spectral analysis technique in order to appraise the hydrocarbon accumulation potential of the area. The regional field was separated with a first order polynomial using polifit program. The residual data was subdivided into 16 spectral blocks allowing spectral probe of 12.5km by 12.5km area for 15minute by 15minute windowing using OASIS MONTAJ software program. Two prominent magnetic depth source layers were identified. The deeper source depth values obtained ranges from 2.33km to less than 5.66km with an average depth of 3.65km as the magnetic basement depth while for the shallower sources, the depth values ranges from 0.07km to less than 0.42km with an average depth of 0.21km. The shallow depth source is attributed to the volcanic rocks that intruded the sedimentary formation and this could possibly be responsible for the mineralization found in parts of the study area. The significance of the magnetic depth value indicate that the sedimentary layer of the Albian Age, Coniacian – Turonian Age, and Turonian – Senonian Age is thick enough to generate hydrocarbon if other conditions are met.
