Multimodal biometrics is expected to be ultra-secure and reliable, due to the presence of multiple and independentverification clues. In this study, a multimodal biometric system utilising audio and facial signatures has been implemented and error analysis has been carried out. A total of one thousand face images and 250 sound tracks of 50 users are used for training the proposed system. To account for the attempts of the unregistered signatures data of 25 new users are tested. The short term spectral features were extracted from the sound data and Vector Quantization was done using K-means algorithm. Face images are identified based on Eigen face approach using Principal Component Analysis. The success rate of multimodal system using speech and face is higher when compared to individual unimodal recognition systems
New Studies of the Structure and the Texts of Abba Garima Ethiopian Gospels
No full textThe article presents a codicological study of the three ancient Ethiopian Gospels of Abba Garima. The author rearranges the sequence of the disordered folios of the manuscripts in detailed tables, proposes a new foliation system and proceeds to catalogue-like descriptions. Attentive inspection of each folio led to the discovery of original quire numbers as well as original and later liturgical annotations put in folio margins, among which there are liturgical rubrics in rare unvocalized consonantal script. Detailed tables of Gospel pericopes and of dates of their liturgical use accompany the descriptions, as well as a discussion of the lectionary system and of the liturgical terminology as attested by the rubrics. The author also discusses philological characteristics of the two subsidiary texts originally included in the Abba Garima manuscripts, ‘Discourse on the Harmony of Gospels’ and ‘Letter of Carpianus’ of Eusebius of Caesarea. The article contains an edition, an English translation and a succint historical commentary of three hitherto inedited donation notes from the 15th-16th centuries.Cet article présente une étude codicologique des trois anciens évangiles éthiopiens du monastère d'Abba Garima. L'auteur réorganise la séquence des folios désordonnés des manuscrits dans des tableaux détaillés, propose un nouveau système de foliation et établit la notice descriptive de chaque manuscrit. Une étude attentive de chaque folio a permis de découvrir les numéros originaux des cahiers. De même, des annotations liturgiques originales et ultérieures ont été découvertes dans les marges des folio. Certaines de ces rubriques liturgiques utilisent une écriture consonantique non vocalisée rare. Des tableaux détaillés des péricopes de l'Évangile et des dates de leur usage liturgique accompagnent les descriptions, de même qu'une discussion sur le système du lectionnaire et sur la terminologie liturgique attestée par les rubriques. L'auteur discute également des caractéristiques philologiques de deux textes subsidiaires inclus à l'origine dans les manuscrits d'Abba Garima, le « Discours sur l'harmonie des Évangiles » et la « Lettre de Carpianus » d'Eusèbe de Césarée. L'article contient pour finir une édition, une traduction anglaise et un commentaire historique succinct de trois notes de donation des XVe-XVIe siècles, jusqu'ici inédites
Hysteroscopic Management of Intrauterine Pathologies: A Case Series of 296 Patients
No full textABSTRACT
Aims
To discuss the incidence of various hysteroscopic findings in patients of infertility, abnormal uterine bleeding (AUB), and postmenopausal bleeding and to compare the prevalence of various uterine pathologies in patients of primary and secondary infertility.
Materials and methods
This is a retrospective observational study, which evaluated 296 patients who underwent diagnostic hysteroscopy for evaluation of primary or secondary infertility, AUB, and postmenopausal bleeding over a period of 18 months in a Gynae-endoscopy Unit. Detailed hysteroscopic evaluation of the endocervical canal and uterine cavity in all recruited cases was done by the same surgeon and the data were collected by reviewing the case records.
Results
Among the 296 cases analyzed, 157 cases were of primary infertility, 81 cases were of secondary infertility, 45 cases were of AUB, and 13 cases presented with postmenopausal bleeding. Among the primary infertility patients, 58.6% had abnormal findings on hysteroscopy, while among the secondary infertility patients, hysteroscopy revealed abnormalities in as high as 72.5% cases. In the present study, uterine synechiae was the most common abnormality detected among the infertile patients. Endometrial polyps were the most common pathology detected among patients with AUB and postmenopausal bleeding.
Conclusion
Hysteroscopy is a minimally invasive and highly safe technique to directly visualize the endocervical canal, uterine cavity, and tubal ostia. It has an added advantage of treating the pathology in the same sitting, thus improving the clinical outcomes. Based on our findings, we conclude that uterine pathologies are a major contributor in causing infertility and menstrual irregularities, which are missed on blind modalities like hysterosalpingography and dilatation and curettage.
Clinical significance
This article stresses on the use of hysteroscopy as a primary diagnostic modality in evaluating patients of infertility, AUB, and postmenopausal bleeding in order to increase the detection rates of uterine pathologies.

TED Talks – A Predictive Analysis Using Classification Algorithms
No full textTED talks are a great source of knowledge and ideas which are available online for free. TED talk encompasses a plethora of topics like Technology, Entertainment, Design, Cultural, Academic Research etc. which are presented by different speakers. The purpose of this study is to develop a model to predict two things – firstly, to predict the number of views for the talks and secondly, to predict the overall reaction of the talks from the description of the comments given by the users. We have used several machine learning classification algorithms like SVM, Logistic Regression, Random Forest, Decision tree and KNN. The dataset for this project includes details of 2550 TED Talks from 2006 to 2017. We have also done some visualizations on the data set to get more understanding of the topic and analyze it further.Open Restriction set for Item 105932 on 2018-05-09T20:07:50Z with date null by [email protected] Restriction set for Item 105932 on 2018-05-10T02:34:07Z with date null by [email protected] by Kumkum Yadav ([email protected]) on 2018-05-10T03:03:50Z

Investigating multilingualism and its association with executive functioning: An exploratory study comparing bilingual, trilingual and quadrilingual college students in India
No full textMultilingualism has both advantages and disadvantages. Past research has highlighted this dichotomy by exploring the impact of linguistic ability on individuals’ executive functioning. This study explores the relationship between individuals’ linguistic ability (number of languages spoken) and their executive functioning, specifically, working memory – measured using the Corsi Block-Tapping task (Mueller, 2011a), inhibitory control – measured using the Go/No-Go task (Mueller, 2011b) and problem solving – measured using the Tower of London task (Mueller, 2011c) among bilingual, trilingual and quadrilingual Indian colleges students. Results from a Kruskal Wallis test indicated non-significant results for problem solving among the three groups. However, significant differences were found between groups for working memory (p = 0.050) (particularly between bilinguals and quadrilinguals, and trilinguals and quadrilinguals) and inhibitory control (p = 0.020) (particularly between trilinguals and quadrilinguals). The mixed results indicate a need for further research in this domain within the vast and diverse population of India.

No full textApplication of Biometrics in Secure Bank Transactions
No full textAbstract The introduction and adoption of remote banking, after hour services through automatic teller machines (ATMs), phone banking, online services and electronic commerce has changed the nature of financial services, giving people the convenience and the flexibility to do so much more with their time and resources. With remote banking, the channels of transaction move outside the walls of the bank, requiring adequate protection for both bank and customer. The ability to verify the identity of a specific individual is of critical importance in reducing acts of fraud and increasing security. Traditional automated verification methods such as ATM cards cannot provide positive identification -they may be lost or stolen, while PINs, passwords and account numbers may be steal or intercepted by unauthorized users through electronic means and other ways. A concerted effort to stop this crime requires a more reliable method of identification that relies on much more than names and social security numbers. It requires a way to truly ascertain a person's identity. Biometrics can be a central component of the solution
