CNN-based anti-spoofing two-tier multi-factor authentication system
No full textMany hybrid and multimodal biometric recognition techniques have been presented to provide secure and authentic systems, incorporating both soft and hard biometric schemes. This article proposes a new hybrid technique which ensures the authenticity of the user to the system, as well as monitors whether the user has passed the biometric system as a normal or spoofed one. The proposed scheme is two-fold: Tier I integrates fingerprint, palm vein print and face recognition to match with the corresponding databases, and Tier II uses fingerprint, palm vein print and face anti-spoofing convolutional neural networks (CNN) based models to detect spoofing. In first stage, the hash of a fingerprint is compared with the fingerprint database. After a successful match of the fingerprint, it is tested on a CNN-based model of the fingerprint to verify whether it is a spoof or real. A similar process is repeated for the palm and face, and based on collective evidence, the system permits the user to login the system. Experimental results over five benchmark datasets verified the effectiveness of the proposed system in providing efficient and robust verification, overcoming the limitations in normal authentication and spoofing practices
al-Misbāh fī al-Nahw By Nāsir al-Dīn al-Mutarrizī al-Nahwī (d. 610/1213) A Critical Edition of the Text with the Life History of the Author
No full textNāsir al-Dīn al-Mutarrizī al-Nahwī (d.610/1213) was one of the most renowned figures in the field of Arabic Grammar. He has left an indelible mark on the world of Arabic language and literature. He is also known as the successor of al-Zamakhsharī.
He wrote a number of books but his al-Misbāh fī al-Nahw gained prominence at a level that no other book in this field could claim to achieve. For this reason, a great number of commentaries have been written in every age, of which the most famous are al-Daw and Khulāsat al-I‘rāb written by Tāj al-Dīn al-Isfrā’īnī and ‘Abd al- Karīm al-Tūsī (better known as Hājjī Bābā) respectively. Moreover, its translation into other languages also demonstrates its value as a useful book.
Although al-Misbāh has been edited on more than one occasion, the published editions do not fulfil the needs and requirements of modern academic research criteria. The basic aim of this thesis is to present this book with a current modern research style so that the students, teachers and ordinary readers of Arabic language and literature may benefit from this work.
This thesis is divided into two parts. The first part deals with the life history of the author and his other works. A brief note of the environment under which he grew up (generally referred to as the ‘Seljuk’ period) is also included in this part.
The second part consists of a text edition that deals with the derivation (Takhrīj) of syntactical issues together with the differing opinions of grammarians on syntactical/grammatical issues. This part also proffers the idiomatic English translation of al-Misbāh

ABSTRACT:
Muhammad Wasil and K.H. Ahmad Ghozali has a history of studying astronomy with Kiai Noor Ahmad Jepara (deceased), author of the book of astronomy Nur al-Anwar. Even so, Muhammad Wasil and K.H. Ahmad Ghozali has a different method for predicting the phenomenon of a solar eclipse. These two calculation methods are often used as references in predicting solar eclipse phenomena, even though they have different final results. This research is intended to answer the questions: (1) What is the method for calculating global solar eclipses by Muhammad Wasil and K.H. Ahmad Ghozali? (2) What is the comparison of the level of accuracy of the global solar eclipse calculation method of Muhammad Wasil and K.H. Ahmad Ghozali? (3) What are the advantages and disadvantages of the global solar eclipse calculation method Muhammad Wasil and K.H. Ahmad Ghozali? Problems are discussed through literature study by collecting data through documentation and interviews. All data is analyzed and compared with NASA results as a reference for accuracy levels.
This research concludes: Firstly, the calculation methods of Muhammad Wasil and K.H Ahmad Ghozali have similarities using the concept of a geocentric ecliptic coordinate system, apart from that there are differences between the two calculation methods including the concept of the shape of the Earth used, data sources, provisions for delta T(∆T), and the approach used in the calculation method. Second, the level of accuracy of the global solar eclipse calculation method K.H. Ahmad Ghozali's calculation method is higher than Muhammad Wasil's in predicting the phenomenon of a solar eclipse. This level of accuracy is based on calculating the state of the greatest eclipse which has a direct impact on the implementation of eclipse prayers. Third, Muhammad Wasil's method for calculating global solar eclipses has the advantage of contacts being calculated more completely, being able to depict a map of the movement of the eclipse, a higher level of accuracy in calculating umbral contacts, while there are disadvantages, namely that it is difficult to implement without the help of a program as a tool. In the calculation method for global solar eclipses, K.H. Ahmad Ghoazali has advantages, including a more practical calculation method, having a high level of accuracy for penumbral contact and the peak of the eclipse (greatest eclipse), while his disadvantages are low accuracy in calculating umbral contact for global solar eclipses.

Poverty Dynamics of Female-headed Households in Pakistan: Evidence from PIHS 2000-01 and PSLM 2004-05
No full textThe paper attempts to empirically test a naïve version of what is rather stylistically termed as “feminisation of poverty”, using the sub-sample of female -headed households (FHHs) from two household surveys in Pakistan. Although, the database is constrained by quality factors and small sample size, the following findings add to the richness of current research in this area: (a) The numerical incidence of poverty among households headed by females is less than that for all households in the country, at the national, urban and rural level for both the years. This can be traced to the finding that more than 70 percent of households headed by females receive remittances, (b) The incidence of poverty among FHHs during the period 2000-01 to 2004-05 did not decline as fast as it did for mixed households, nationwide. In urban areas, it did not decline at all, (c) Among the determinants of poverty of FHHs, illiteracy, dependency and rural residence exacerbate poverty, while remittances domestic and/ or foreign reduce poverty, (d) The dynamics of incidence of poverty among FHHs during the period indicated that Illiteracy as the factor exacerbating poverty became less important in 2004-05. Moreover, residence in rural areas was also a weaker factor in determining the incidence of poverty. By far the most notable contribution in reducing the incidence of poverty was self-employment in agriculture in 2004-05.
Conversion of African Americans to Islam : a sociological analysis of the Nation of Islam and associated groups
No full text'Conversion of African Americans to Islam: A Sociological Analysis of the Nation of
Islam Associated groups' is an empirical study of the religious experience of people
who had/have distinctive features in terms of race, ethnicity and historical experience.
The purpose of this thesis is to demonstrate how African Americans' (AAs) conversion
experience in general, and the Nation of Islam associated groups' conversion in
particular, differ from the studies of recruitment and conversion in the sociology of
religion and New Religion Movements (NRMs). More specifically, their recruitment
and conversion experiences to Islam diverge from those who converted to mainstream
Islam. The study investigates how AAs' historical experience, soci-economic
difficulties and the racism they encountered shaped and influenced their religious
understanding.
Research methods involved participant observations, a survey questionnaire, interviews,
conversations, personal communications and correspondence. To collect ethnographic
data eleven months field research was conducted mainly in the Chicago area and on two
short visits to Detroit, and three years continued communications with Muslim officials
and academics in the area. During the field research and afterwards through personal
communication 181 survey questionnaire responses were received, and 23 Muslim
officials, academics and ordinary Muslims were interviewed through semi-structured,
unstructured interviews, conversation and correspondence.
The thesis begins with a brief history of Islam and Muslims in general and the African
American Muslims (AAMs) in particular. More emphasis is given on the historical
development of the Nation of Islam (NOl). Then in Chapter III, discussions of schisms
in the history of the NOT are examined from sociological perspectives of social and
religious movements. In Chapter IV I aimed to formulate my own perspective to
analyse and study the conversion experiences of AAMs to Islam. I used a multivariate
approach, considering selectively widely held conversion and recruitment theories in the
sociology of the religion. I consider in Chapter V the predisposing conditions for AAMs
that influence their decision-making to join in the NOT, for example, political and
nationalistic sentiments and socio-economic deprivations. In Chapter VI I have applied
different terms to describe their religious experiences, such as conversion, alteration and
reversion. I have analysed further their encounters with the NOT, the methods of
recruitment they used and their major motives for joining the NOT and converting to
Tslam. In the concluding chapters (Chapter VII VTTT) I describe the different responses
of AAMS to Islam following the death of Elijah Muhammad. It is found out that the
Islamic appeal has polarised. While Farakhan's NOT appeared to continue the tradition
and style of the old NOI with the emphasis on nationalistic and socio-economic factors,
Tmam W. D. Mohammed's community turned more to the religious and spiritual aspects
of Tslam. These different approaches led to a polarisation of the appeal of Tslam to
AAMS.
This thesis contributes to knowledge in four key areas; the sociology of religion and
religious movements, the sociology of social and nationalistic movements, religious and
Islamic studies

We measured exciton diffusion and fluorescence quenching in such blends by dispersing fullerene molecules into them. We find that the diffusion length is more than two times higher in the semicrystalline copolymer than in the amorphous copolymer. We also find that fullerene preferentially mixes into disordered regions of the polymer film. This shows that relatively small differences in molecular structure are important for exciton diffusion and fullerene distribution.Peer reviewe
Application of terahertz sensing at nano-scale for precision agriculture
No full textThis chapter employs the state‐of‐the‐art terahertz technique, the focus is primarily to introduce a preliminary analysis and to investigate the water content and presence of any pesticides in leaves in the range of 0.75 to 1.2 THz frequency using the Swissto12 system. It aims at determining the path‐loss response and the complex permittivity of leaves of fresh and drought stressed leaves. In order to obtain higher accuracy and an effective use of water in the agriculture sector, terahertz sensing has potential and is deemed to have a faster, reliable response for the overall monitoring and maintaining the health of the leaves. In modern agriculture, the progress of biosensors plays a vital role in improving both the quantity and quality of yields due to the properties of nanomaterials. The chapter emphasizes the advancement and development of terahertz technology applications in the agriculture sector and presents some of the preliminary studies done in this domain
Reaction, diffusion and dissociation of excitons on carbon nanotubes
No full textPhotoexcitation of carbon nanotubes generates excitons which decay by exciton-exciton annihilation at sufficient density. We examine this decay under conditions of one, few and many excitons per nanotube. A classic ID reaction-diffusion behaviour is observed, with decay limited by diffusion for t>3ps and by reaction for t<3ps. At high densities the exciton population saturates, and by analysis of the rate equations we show that this is consistent with dissociation of excitons when their spacing is 1.3nm, close to the exciton length. ©2010 Optical Society of America
Annotation of conceptual co-reference and text Mining the Qur'an
No full textThis research contributes to the area of corpus annotation and text mining by developing novel domain specific language resources. Most practical text mining applications restrict their domain. This research restricts the domain to the Qur'anic Text.
In this thesis, a number of pre-processing steps were undertaken and annotation information were added to the Qur'an. The raw Arabic Qur'an was pre-processed into morphological units using the Qur'anic Arabic Corpus (QAC). Qur'anic terms were indexed and converted into a vector space model using techniques in Information Retrieval (IR). In parallel, nearly 24,000 Qur'anic personal pronouns were annotated with information on their referents. These referents are consolidated and organized into a total of over 1,000 ontological concepts. Moreover, a dataset of nearly 8,000 pairs of related Qur'anic verses are compiled from books of scholarly commentary on the Qur'an. This vector space model, the pronoun tagging, the verse relatedness dataset, and the part-of-speech tags available in QAC all together served for a number of Qur'anic text mining applications which were rendered online for public use. Among these applications: lemma concordance, collocation, POS search of the Qur'an, verse similarity measures, concept clouds of a given verse, pronominal anaphora and Qur'anic chapter similarity.
Furthermore, machine learning experiments were conducted on automatic detection of verse similarity/relatedness as well as categorization of Qur'anic chapters based on their chronology of revelation. Domain specific linguistic features were investigated to induct learning algorithms. Results show that deep linguistic and world knowledge is needed to reach the human upper bound in certain computational tasks such as detecting text relatedness, question answering and textual entailment. However, many useful queries can be addressed using text mining techniques and layers of annotations made available through this research. The works presented here can be extended to include other similar texts like Hadith (i.e., saying of Prophet Muhammad), or other scriptures like the Gospels
