Spectral Symmetry Analysis

We present a spectral approach for detecting and analyzing rotational and reflectional symmetries in n-dimensions. Our main contribution is the derivation of a symmetry detection and analysis scheme for sets of points IRn and its extension to image analysis by way of local features. Each object is represented by a set of points S ∈ IRn, where the symmetry is manifested by the multiple self-alignments of S . The alignment problem is formulated as a quadratic binary optimization problem, with an efficient solution via spectral relaxation. For symmetric objects, this results in a multiplicity of eigenvalues whose corresponding eigenvectors allow the detection and analysis of both types of symmetry. We improve the scheme's robustness by incorporating geometrical constraints into the spectral analysis. Our approach is experimentally verified by applying it to 2D and 3D synthetic objects as well as real images.
Bedouin Children and Their Reality Perceptions of the War Between Israel and Gaza

Abstract In the military conflict between Israel and Gaza, the Bedouins in Israel find themselves under attack by rockets launched from Gaza, and at the same time identifying with family members in Gaza who suffer casualties as a result of Israel’s operations. Bedouin children experience a threat to their safety, and are required to enter protected spaces when the siren sounds. Simultaneously, they are exposed to the Arab media, which one-sidedly views Israel as the aggressor. This study examines this complex situation from the perspective of Bedouin children aged 8–10, using children’s drawings and letters, interviews, and conversations with their mothers. The findings reflect the children’s complicated impression of the world, manifested in identification with the residents of Gaza and their suffering, anxiety concerning their own safety, and development of post-traumatic stress disorder. They have difficulty constructing a coherent picture of the world, and develop perceptions containing distortions of reality with regard to aggressor and victim. The findings indicate the need for professional intervention which, in addition to building a psychological assistance system, would provide parents with guidance to help them mediate the complex reality for their children in a structured and informed way, and hence enable them to better contend with it. ‏
Hierarchical voting classification scheme for improving visual sign language recognition

As one of the important research areas of multimodal interaction, sign language recognition (SLR) has attracted increasing interest. In SLR, especially on medium or large vocabulary, it is usually difficult or impractical to collect enough training data. Thus, how to improve the recognition on the limited training samples is a significant issue. In this paper, a simple but effective hierarchical voting classification (HVC) scheme for improving visual SLR, which makes efficient use of limited training data, is proposed. The key idea of HVC scheme is similar to but not the same as Bagging technique. Firstly, it constructs several training sets from the original training set in a combinatorial fashion to generate the corresponding continuous hidden Markov models (CHMM) ensemble. Then, it determines the ensemble output by appropriate local voting strategy. Finally, it obtains the final recognition result by the global voting. Experimental results show that the HVC scheme outperforms the conventional single CHMM approach in terms of recognition accuracy on the limited training data.
Intention Is Commitment with Expectation 375

Modal logics with possible worlds semantics provide a means to describe the rational behavior of agents in terms of mental states, such as beliefs, goals, and intentions. Agen t’s beliefs and goals are typically represented in these logics by primitive modal operators. However, the representation of agent’s intentions varies greatly between theories. Som e logics characterize intention as a primitive operator, whi le others define intention in terms of more primitive construct s. Taking the latter approach is a theory due to Cohen and Levesque ( Cohen & Levesque 1990 ), under which intentions are a special form of commitment or persistent goal. The theory has motivated theories of speech acts and joint intention and innovative applications in multiagent syste ms and industrial robotics. However, Singh ( Singh 1992) shows the theory to have certain logical inconsistencies and permit certain absurd scenarios. We present a modification of the theory that preserves the desirable aspects of the origi nal while addressing the criticism of Singh. This is achieve d by the introduction of an additional operator describing th e achievement of expectations, refined assumptions, and new definitions of intention. The modified theory gives a cogent account of the rational balance between agents’ action and deliberation, and suggests the use of means-ends reasoning in agent implementations.
Regulation of Arabidopsis shoot apical meristem and lateral organ formation by microRNA miR166g and its AtHD-ZIP target genes

Plant development is characterized by precise control of gene regulation, leading to the correct spatial and temporal tissue patterning. We have characterized the Arabidopsis jabba-1D (jba-1D) mutant, which displays multiple enlarged shoot meristems, radialized leaves, reduced gynoecia and vascular defects. The jba-1D meristem phenotypes require WUSCHEL (WUS) activity, and correlate with a dramatic increase in WUS expression levels. We demonstrate that the jba-1D phenotypes are caused by over-expression of miR166g, and require the activity of the RNase III helicase DCL1. miR166g over-expression in jba-1D plants affects the transcripts of several class III homeodomain-leucine zipper (AtHD-ZIP) family target genes. The expression of PHABULOSA (PHB), PHAVOLUTA (PHV) and CORONA (CNA) is significantly reduced in a jba-1D background, while REVOLUTA (REV) expression is elevated and ATHB8 is unchanged. In addition, we show that miR166 has a dynamic expression pattern in wild-type and jba-1D embryos. Our analysis demonstrates an indirect role for miRNAs in controlling meristem formation via regulation of WUS expression, and reveals complex regulation of the class III AtHD-ZIP gene family.
VICISITUDES DE LA VIDA AMOROSA: CUANDO EL ODIO SUBYACE AL AMOR Vicissitudes of the love life: When hate underlies love

The contemporary difficulties of love life have become a pervasive theme. In clinical psychology, it is commonly observed that subjects are afflicted by the characteristics of their emotional ties. Unsuccessful partner choices and unsatisfactory relationships seem to be determined by internal variables rather than random experiences. Early experiences in relations determine the quality of future love bonds, including the tendency to repeat, as a way of remembering and elaborating these experiences which, in turn, lead to successive failures and the inability to break degrading bonds. The present paper revises the concept of love as proposed by psychoanalytic theory and the numerous psychological proces
Resolving Coreferent and Associative Noun Phrases in Scientific Text

We present a study of information status in scientific text as well as ongoing work on the resolution of coreferent and associative anaphora in two different scientific disciplines, namely computational linguistics and genetics. We present an annotated corpus of over 8000 definite descriptions in scientific articles. To adapt a state-of-the-art coreference resolver to the new domain, we develop features aimed at modelling technical terminology and integrate these into the coreference resolver. Our results indicate that this integration, combined with domain-dependent training data, can outperform the performance of an out-of-the-box coreference resolver. For the (much harder) task of resolving associative anaphora, our preliminary results show the need for and the effect of semantic features.
A multi-gigabit rate deep packet inspection algorithm using TCAM

With the increasing importance of network protection from cyber threats, it is requested to develop a multi-gigabit rate pattern-matching method for protecting against malicious attacks in high-speed network. This paper devises a high-speed deep packet inspection algorithm with TCAM by using an m-byte jumping window pattern-matching scheme. The proposed algorithm significantly reduces the number of TCAM lookups per payload by m times with the marginally enlarged TCAM size which can be implemented by cascading multiple TCAMs. Due to the reduced number of TCAM lookups, we can easily achieve multi-gigabit rate for scanning the packet payload. It is shown by simulation that for the Snort rule with 2,247 patterns, our proposed algorithm supports more than 10 Gbps rate with a 9 Mbit TCAM.
Multimodal Signature Verification Using Fractal Dimension

Data glove is a new dimension in the field of signature verification, which can reflect the identity of a person and that renders the forging process nearly impossible. Multiple biometric modalities can overcome some of the practical limitations of current unimodal biometric technologies. In this work an online signature verification system and image verification system are combined as these modalities are widely accepted and natural to produce. Singular value decomposition techniques are applied for image extraction and fractal dimension to extract the feature values of different sensors locating on corresponding fingers in the signing process and evaluated the results for writer authentication. Finally the similarity factor is compared with the decision threshold for accepted or rejected as genuine or forgery, respectively. This paper presents a novel user authentication system based on a combined acquisition of signature using Data Glove signals and face images from webcam. I. INTRODUCTION Biometrics is an emerging field of technology devoted to identification of individuals by employing biological traits, such as those used for iris scanning, fingerprinting, face recognition, and others. Signatures of some people vary a lot: even the successive impressions of their signature are significantly different. Further, the professional forgers can reproduce signatures to fool the unskilled eye. Although, the human experts can discriminate genuine signatures from the forged ones, modeling the invariance in the signatures and automating signature recognition process are challenging. In off-line systems for which the signature is captured once the writing processing is over, and thus only a static image is available [2] [3]. On-line approaches to signature recognition: Input devices in this category are either digitizing tables or smart pens and hand gloves [2]. In digitizing table-based systems both global and local features that summarize aspects of signature shape and dynamics of signature production are used for signature verification.
Mining GitHub: Why Commit Stops -- Exploring the Relationship between Developer's Commit Pattern and File Version Evolution

Using the freeware in GitHub, we are often confused by a phenomenon: the new version of GitHub freeware usually was released in an indefinite frequency, and developers often committed nothing for a long time. This evolution phenomenon interferes with our own development plan and architecture design. Why do these updates happen at that time? Can we predict GitHub software version evolution by developers' activities? This paper aims to explore the developer commit patterns in GitHub, and try to mine the relationship between these patterns (if exists) and code evolution. First, we define four metrics to measure commit activity and code evolution: the changes in each commit, the time between two commits, the author of each changes, and the source code dependency. Then, we adopt visualization techniques to explore developers' commit activity and code evolution. Visual techniques are used to describe the progress of the given project and the authors' contributions. To analyze the commit logs in GitHub software repository automatically, Commits Analysis Tool (CAT) is designed and implemented. Finally, eight open source projects in GitHub are analyzed using CAT, and we find that: 1) the file changes in the previous versions may affect the file depend on it in the next version, 2) the average days around "huge commit" is 3 times of that around normal commit. Using these two patterns and developer's commit model, we can predict when his next commit comes and which file may be changed in that commit. Such information is valuable for project planning of both GitHub projects and other projects which use GitHub freeware to develop software.
Syndrome de Gilles de la Tourette et thérapeutiques : revue de littérature

Le syndrome de Gilles de la Tourette (SGT) est un trouble neurodeveloppemental caracterise par la presence de tics chroniques, moteurs et au moins un vocal, survenant pendant plus d’un an avant la majorite. Il est presque toujours associe a des comorbidites psychiatriques : le trouble deficitaire de l’attention avec ou sans hyperactivite (TDA/H) et le trouble obsessionnel compulsif (TOC) principalement. L’heterogeneite clinique constatee chez les differents patients pose la question du meilleur traitement disponible aujourd’hui. L’objectif de ce travail est de proposer une prise en charge medicale consensuelle pour traiter un sujet atteint par le SGT, via une revue de la litterature medicale. Les techniques de therapies cognitivo-comportementales (TCC) se trouvent en premiere ligne pour les individus presentant des tics legers. La pharmacotherapie est recommandee si la TCC n’est pas efficace, ou si les tics sont d’emblee severes et invalidants. L’aripiprazole est la molecule de reference dans le traitement des tics – tant pour son efficacite que pour son excellente tolerance. D’autres neuroleptiques, tels que la risperidone ou le pimozide, sont a envisager si l’aripiprazole n’est pas concluant. Enfin, lorsque le sujet continue a presenter un handicap fonctionnel majeur lie aux tics, resistant a la TCC et a la pharmacologie, un traitement chirurgical avec mise en place d’une stimulation cerebrale profonde (SCP) est indique.
Modified SET protocol for mobile payment: An empirical analysis

The wide spread of using handheld devices offers an opportunity for mobile devices to be used as a universal payment method. However, some issues impede the widespread acceptance of mobile payment; for example: privacy protection, limited capability of mobile devices, and limited bandwidth of wireless networks. In ecommerce payment, Secure Socket Layer (SSL) protocol has been used to establish a secure channel between customers and merchants to secure the payment and the order information. SSL has some disadvantages regarding customer privacy that the customer payment information is revealed to the merchant. Secure Electronic Transaction (SET) has resolved SSL protocol disadvantages by dividing order message into: 1) order information which is revealed to merchant M, 2) payment information which is revealed to Payment Gateway (PG). Both SSL and SET assume the existence of Public Key Infrastructure (PKI) where extensive computations are carried out. In mobile payment, the same protocols of ecommerce payment are used but their application is limited due to heavy computations over wireless and GSM networks. A Modified Secure Electronic Transaction (MSET) protocol is proposed to minimize the extensive computations of SET protocol through replacing time consuming public key encryption and decryption algorithms by symmetric key cryptography.
SECURITY ENGINEERING: A GUIDE TO BUILDING DEPENDABLE DISTRIBUTED SYSTEMS

135 PART Two In the second part of the book, I describe a large number of applications of secure systems , many of which introduce particular protection concepts or technologies. There are four successive themes. Chapters 7 through 9 look at conventional computer security issues, and by discussing what one is trying to do and how it's done in different environments—the military, banks, and healthcare—I introduce security policy models, which set out the protection concepts that real systems try to implement. I also introduce the first detailed case studies in these chapters. An example is the worldwide network of automatic teller machines, which illustrates many of the problems of transferring familiar protection properties from a bank branch to a global distributed environment using cryptography. Chapters 10 through 15 look at the hardware engineering aspects of information security. This includes biometrics, the design of various tokens such as smartcards, tamper resistance and tamper evidentness, emission security, and seals. New applications that illustrate the technologies are described, ranging from electronic warfare and nuclear weapons control to taximeters, truck speed limiters, and prepayment gas meters. The third theme is attacks on networks. I start off in Chapter 16 by covering electronic and information warfare, as these activities give some of the more extreme examples and show how far techniques of denial, deception, and exploitation can be taken by a resourceful opponent under severe operational pressure. This chapter also gives a view of surveillance and intrusion from the point of view of police forces and intelligence agencies, and introduces a number of new concepts, such as anonymity and traffic analysis. We then study the lessons of history by examining frauds on phone systems and on applications that rely on them in Chapter 17. This sets the scene for a discussion in Chapter 18 of attacks on computer networks and defensive technologies such as firewalls and intrusion detection. The fourth theme is electronic commerce, which I tackle in Chapters 19 and 20. The most high-profile applications are schemes for protecting credit card transactions on the Net, such as SSL/TLS; they are also used for other applications such as medical image distribution. They introduce the debate about public key infrastructures. In addition , I consider mechanisms for copyright protection, specifically, pay-TV, DVD, and copyright watermarking.
UWB U- shaped planar printed antenna loaded with annular ring slot and tuning stubs

In this paper, a new configuration of UWB planar printed compact monopole antenna has been presented. The proposed antenna comprising of U-shaped notch loaded with tuning stubs and annular ring slot. It has a partial ground plane to achieve an excellent impedance matching to increase the impedance bandwidth. The simulated results show that the proposed antenna exhibits UWB for 4.32 GHz to 12.92 GHz with -10dB return loss and VSWR <; 2. Antenna gain and radiation pattern plots for different frequencies are also investigated. The performance characteristics of the proposed antenna is confirmed by simulated results using Ansoft HFSS software.
Policy or Empowerment? Policy Environments, Political Empowerment, and Work–Family Conflict

Abstract Purpose To investigate the association between country-level differences in childcare enrollment, the presence of affirmative action policy, and female parliamentary representation and individual-level conflict between work and family. Methodology/approach This study applies data from the 2002 International Social Survey Program (n = 14,000 + ) for respondents in 29 countries and pairs them with macro-level measures of childcare enrollment, the presence of affirmative action policy, and female parliamentary representation. I estimate the model using hierarchical linear modeling (HLM 7) and also assess cross-level interactions by gender and parental status. Findings The models show that female parliamentary representation has a robust negative association with individual-level reports of work–family and family–work conflict. These associations do not vary by gender or parental status. Also, mothers report less family–work conflict in countries with more expansive childcare enrollment, indicating that this welfare policy benefits the intended group. Research limitations/implications This research implies that greater female parliamentary representation has widespread benefits to all citizens’, rather than just women’s or mothers’, work–family and family–work conflict. Additional longitudinal research would benefit this area of study. Practical implications This research suggests that increasing female parliamentary representation at the country-level may promote work–life balance at the individual-level. It also indicates that public childcare enrollment benefits women through lower family–work conflict which may encourage continuous maternal labor force participation and reduce economic gender inequality. Originality/value This chapter builds on an emerging area of work–family research applying multilevel modeling to draw empirical links between individual work–family experiences and macro-level structural variation.

Power distribution network model of Jail substation of Guwahati city for EMT analysis

It is well known that, electrical power distribution network (PDN) is a very complex dynamic system. In order to analyze instantaneous behavior of PDN, an efficient Electromagnetic Transient (EMT) simulation framework is required. In this paper a PDN model of substation of Guwahati city, India is presented for EMT analysis. The EMT problem formulation is based on trapezoidal integration for lumped network parameters. A comparative study on different iterative solvers used for EMT analysis is presented. Simulation results of these iterative solver and a direct solver (simulink) are also compared, to verify accuracy of the proposed model.
Work-life conflict among young academics: antecedents and gender effects

ABSTRACT Aligning work and private life is a significant challenge for young academics because of demanding working conditions (e.g. high workload, low job security). It is particularly strong for young female academics due to growing family responsibilities. Our study aims to identify the factors influencing the work-life conflict of young academics and to test whether their effects are different according to gender. Thereby we differentiate between a conflict that arises in the work domain (work-to-life conflict) and a conflict that has its origins in the private-life domain (life-to-work conflict). Our analysis of an online survey in Germany shows that career insecurity and lacking mentor support increases both types of conflicts. Excessive working hours and attempts to segment work and private life increase the work-to-life conflict, while children increase a life-to-work conflict. We find that young female academics experience the conflict-intensifying effects of long work hours and lack of mentor support more strongly than their male counterparts do.
