Synchronous-frame current control of multiphase synchronous motor under asymmetric fault condition due to open phases

In this paper, a synchronous-frame current controller of a multiphase synchronous motor with open phases is proposed. The proposed method cannot only possess the superiority of a linear controller over the conventional hysteresis-type current controller but it also enables the current to be regulated without a steady-state error. The key idea is that all the harmonics of the current and voltage, which can still contribute to the torque positively, can be equivalently represented as dc components even under asymmetric fault conditions. Throughout this paper, a five-phase synchronous motor with one open phase is used as a practical example, and the basic concepts can be easily extended into an n-phase ac motor with multiple open phases, which has the arbitrary number or configuration of the remaining healthy phases. Experimental results prove the validity of the proposed modeling and control algorithm
A Qualitative Study of Voluntarily Transient Young Adults in Portland, Oregon

A qualitative study of voluntarily transient young adults’ experience of homelessness was conducted. Twenty male and female 18to 24-year-olds who had been homeless for at least a 2-week period when housing resources were available were interviewed about their daily lives. Through a grounded theory qualitative analysis of structured interviews, themes were identified and a theory developed. Categories included catalysts leading to homelessness, adaptations to homelessness, a sense of loss, overcoming obstacles, reconnecting, and a renewed sense of purpose and hope.

Vicarious traumatisation experiences among South African Police Service members in a rural setting: An exploratory study

The objective of this study was to explore the vicarious traumatisation experiences of South African Police Service members serving in a rural community. The participants consisted of 17 purposively selected police members (females = 4; age range 27 to 55; average years of police service = 10.6 years). Unstructured face-to-face interviews were conducted on the members’ experiences with trauma events where they were called upon to provide police services. Additionally, field notes, telephone follow-ups, and diaries were used to collect data from the members. The data were analysed using interpretative phenomenological approach guidelines. Findings show the police members to report their outlook on life to change from viewing work-life as routine and impersonal, to viewing it as involved and personal. The police members also reported psychological disorientation and being in a sense of stupor from exposure to traumatic cases. Finally, the police members self-reported empathetic experiences with the survivors as concerned citizen parents.
Video Segmentation by Event Detection: A Novel One-class Classification Approach

Segmenting videos into meaningful image sequences of some particular activities is an interesting problem in computer vision. In this paper, a novel algorithm is presented to achieve this semantic video segmentation. The goal is to make the system work unsupervised and generic in terms of application scenarios. The segmentation task is accomplished through event detection in a frameby-frame processing setup. For event detection, we use a one-class classification approach based on Gaussian processes, which has been proved to be successful in object classification. The algorithm is tested on videos from a publicly available change detection database and the results clearly show the suitability of our approach for the task of video segmentation.
Clarifying the Explanatory Scope of the Dual Implicit Process Model

We thank the commentators for such thought-provoking and insightful critiques of our target article (March, Gaertner, & Olson, this issue). Their varied theoretical orientations provided interesting analyses and challenging assessments of our dual implicit process model (DIPM). We organized our response into three sections. Some of the issues identified in the commentaries suggest a need to clarify the explanatory goals of the DIPM. So, we capitalize on this unique opportunity and first clarify the scope of the model by addressing what it is and what it is not. Next, we consider common issues expressed across commentaries. Finally, we consider idiosyncratic issues unique to particular commentaries.
CALD: Surviving Various Application-Layer DDoS Attacks That Mimic Flash Crowd

Distributed denial of service (DDoS) attack is a continuous critical threat to the Internet. Derived from the low layers, new application-layer-based DDoS attacks utilizing legitimate HTTP requests to overwhelm victim resources are more undetectable. The case may be more serious when such attacks mimic or occur during the flash crowd event of a popular Website. In this paper, we present the design and implementation of CALD, an architectural extension to protect Web servers against various DDoS attacks that masquerade as flash crowds. CALD provides real-time detection using mess tests but is different from other systems that use resembling methods. First, CALD uses a front-end sensor to monitor the traffic that may contain various DDoS attacks or flash crowds. Intense pulse in the traffic means possible existence of anomalies because this is the basic property of DDoS attacks and flash crowds. Once abnormal traffic is identified, the sensor sends ATTENTION signal to activate the attack detection module. Second, CALD dynamically records the average frequency of each source IP and check the total mess extent. Theoretically, the mess extent of DDoS attacks is larger than the one of flash crowds. Thus, with some parameters from the attack detection module, the filter is capable of letting the legitimate requests through but the attack traffic stopped. Third, CALD may divide the security modules away from the Web servers. As a result, it keeps maximum performance on the kernel web services, regardless of the harassment from DDoS. In the experiments, the records from www.sina. com and www.taobao. com have proved the value of CALD.
Detection of loitering individuals in public transportation areas

This paper presents a vision-based method to automatically detect individuals loitering about inner-city bus stops. Using a stationary camera view of a bus stop, pedestrians are segmented and tracked throughout the scene. The system takes snapshots of individuals when a clean, nonobstructed view of a pedestrian is found. The snapshots are then used to classify the individual images into a database, using an appearance-based method. The features used to correlate individual images are based on short-term biometrics, which are changeable but stay valid for short periods of time; this system uses clothing color. A linear discriminant method is applied to the color information to enhance the differences and minimize similarities between the different individuals in the feature space. To determine if a given individual is loitering, time stamps collected with the snapshots in their corresponding database class can be used to judge how long an individual has been present. An experiment was performed using a 30-min video of a busy bus stop with six individuals loitering about it. Results show that the system successfully classifies images of all six individuals as loitering.
Undergraduate performance assessment: Attitudes towards and acceptance of OSCEs among 4th year medical students

Introduction: Objective Structured Clinical Examination (OSCE) is considered a useful method of assessing clinical skills besides Multiple Choice Questions (MCQs) and clinical evaluations. Aim: To explore the acceptance of medical students to this assessment tool in medical education and to determine whether the assessment results of MCQs and faculty clinical evaluations agree with the respective OSCE scores of 4th year medical students (Med IV). Methods: performance of a total of 223 Med IV students distributed on academic years 2006-2007, 2007-2008, and 2008-2009 in OSCE, MCQs and faculty evaluations were compared. Out of the total 93 students were asked randomly to fill a questionnaire about their attitudes and acceptance of this tool. The OSCE was conducted every two months for two different groups of medical students who had completed their family medicine rotation, while faculty evaluation based on observation by assessors was submitted on a monthly basis upon the completion of the rotation. The final exam for the family medicine clerkship was performed at the end of the 4thacademic year, and it consisted of MCQsResults: Students highly commended the OSCE as a tool of evaluation by faculty members as it provides a true measure of required clinical skills and communication skills compared to MCQs and faculty evaluation. The study showed a significant positive correlation between the OSCE scores and the clinical evaluation scores while there was no association between the OSCE score and the final exam scores.Conclusion: Student showed high appreciation and acceptance of this type of clinical skills testing. Despite the fact that OSCEs make them more stressed than other modalities of assessment, it remained the preferred one.
Joint factor graph detection for LDPC and STBC coded MIMO systems: A new framework

By modeling the corresponding MIMO channel as a factor graph (FG), STBC decoder, bit interleaver and LDPC decoder can be combined together to form a larger joint factor graph (JFG). Extrinsic information transfer (EXIT) charts and bit error rate (BER) results show that the JFG enables a shuffled decoding superior to the classical serial iterative detection in performance while reducing complexity.
Perbandingan kemampuan penalaran Matematika dalam memecahkan masalah antara siswa bertipe kepribadian Ekstrovert dan Introvert

Penalaran erat kaitannya dengan tipe kepribadian, karena penalaran merupakan aktivitas berpikir dalam pengambilan keputusan. Sedangkan tipe kepribadian berkenaan dengan sikap yang dilakukan dalam pengambilan sebuah keputusan. Siswa yang berbeda tipe kepribadiannya bisa saja memiliki cara yang tidak sama dalam belajar dan memahami materi pelajaran matematika, sehingga penalarannya pun juga berbeda. Berdasarkan latar belakang tersebut, tujuan dari penelitian ini adalah untuk mengetahui ada atau tidaknya perbedaan kemampuan penalaran matematika dalam memecahkan masalah pada siswa bertipe kepribadian ekstrovert dan introvert. Penelitian ini merupakan penelitian komparatif dengan pendekatan kuantitatif. Populasi dalam penelitian ini adalah siswa kelas XII SMA Negeri 3 Sidoarjo, dengan menggunakan siswa kelas XII MIPA 7 sebagai sampel penelitian. Sampel dikelompokkan ke dalam dua kategori, yaitu siswa bertipe kepribadian ekstrovert dan siswa bertipe kepribadian introvert. Kemudian masing-masing kelompok diberikan tes kemampuan penalaran matematika dalam memecahkan masalah. Selanjutnya dilakukan uji normalitas dan homogenitas data. Setelah itu dianalisis menggunakan uji kesamaan dua rata-rata (uji-t) untuk mengetahui ada atau tidaknya perbedaan kemampuan penalaran matematika dalam memecahkan masalah antara siswa bertipe kepribadian ekstrovert dan siswa bertipe kepribadian introvert.Dari hasil uji hipotesis kesamaan dua rata-rata (uji-t) didapat thitung sebesar 2,1362 sedangkan ttabel sebesar 2,0555, sehingga nilai thitung > ttabel. Hasil uji hipotesis menunjukkan penolakan terhadap H0, sehingga dapat disimpulkan bahwa ada perbedaan yang signifikan kemampuan penalaran matematika dalam memecahkan masalah antara siswa bertipe kepribadian ekstrovert dan siswa bertipe kepribadian introvert.
The ISL meeting corpus: the impact of meeting type on speech style

Speech research is becoming very interested in new application domains, such as meeting summarization and automatic transcription, and has thus begun to work with recorded meeting data. The following paper gives an overview of the meeting data collection at Interactive Systems Laboratories. There are currently over 100 meetings of different types recorded. An experiment is described which aimed at testing the possibility of controlling issues of speaking style by meeting type. Results show that depending on the meeting type, speaking style varies in terms of turn length, speed and disfluencies.
Dysfunction of Immune Systems and Host Genetic Factors in Hepatitis C Virus Infection with Persistent Normal ALT

Patients with chronic hepatitis C (CHC) virus infection who have persistently normal alanine aminotransferase levels (PNALT) have mild inflammation and fibrosis in comparison to those with elevated ALT levels. The cellular immune responses to HCV are mainly responsible for viral clearance and the disease pathogenesis during infection. However, since the innate and adaptive immune systems are suppressed by various kinds of mechanisms in CHC patients, the immunopathogenesis of CHC patients with PNALT is still unclear. In this review, we summarize the representative reports about the immune suppression in CHC to better understand the immunopathogenesis of PNALT. Then, we summarize and speculate on the immunological aspects of PNALT including innate and adaptive immune systems and genetic polymorphisms of HLA and cytokines.
Flux superpotential in heterotic M theory

We derive the most general flux-induced superpotential for N=1 M-theory compactifications on seven-dimensional manifolds with SU(3) structure. Imposing the appropriate boundary conditions, this result applies for heterotic M-theory. It is crucial for the latter to consider SU(3) and not G_2 group structure on the seven-dimensional internal space. For a particular background that differs from CY(3) x S^1/Z_2 only by warp factors, we investigate the flux-generated scalar potential as a function of the orbifold length. We find a positive cosmological constant minimum, however at an undesirably large value of this length. Hence the flux superpotential alone is not enough to stabilize the orbifold length at a de Sitter vacuum. But it does modify substantially the interplay between the previously studied non-perturbative effects, possibly reducing the significance of open membrane instantons while underlining the importance of gaugino condensation.
Interaction of visual hemifield and body view in biological motion perception

The brain network for the recognition of biological motion includes visual areas and structures of the mirror‐neuron system. The latter respond during action execution as well as during action recognition. As motor and somatosensory areas predominantly represent the contralateral side of the body and visual areas predominantly process stimuli from the contralateral hemifield, we were interested in interactions between visual hemifield and action recognition. In the present study, human participants detected the facing direction of profile views of biological motion stimuli presented in the visual periphery. They recognized a right‐facing body view of human motion better in the right visual hemifield than in the left; and a left‐facing body view better in the left visual hemifield than in the right. In a subsequent fMRI experiment, performed with a similar task, two cortical areas in the left and right hemispheres were significantly correlated with the behavioural facing effect: primary somatosensory cortex (BA 2) and inferior frontal gyrus (BA 44). These areas were activated specifically when point‐light stimuli presented in the contralateral visual hemifield displayed the side view of their contralateral body side. Our results indicate that the hemispheric specialization of one's own body map extends to the visual representation of the bodies of others.
Factors affecting the intention to use e-Government services

Nowadays, more and more people are using Information and Communication Technologies (ICTs) in order to accommodate their daily needs. E-Government (e-Gov) adopts these technologies in an effort to provide prompt and secure services to citizens. However, the intention to use e-Government services has not yet been fully examined by the international literature. The present research attempts to bridge this gap, by examining the factors affecting citizens' intention to use e-Government services. In that direction, a conceptual framework (research model), based on an extensive review of the relevant literature, has been developed. The proposed conceptual framework has been empirically tested using a newly-developed structured questionnaire. Data were collected from a sample of 547 Greek citizens. The reliability and the validity of the questionnaire have been thoroughly examined, while the Structural Equation Modeling (SEM) technique has been used to analyze the data. Results indicate that perceived usefulness is the most important determinant of the intention to use e-Government services. Other important factors are perceived trust, internet experience, peer influence, computer self-efficacy and perceived risk.
The role of the core and extended face networks in visual perception and high level social cognition - Trust game, an fMRI study

The present project aims to have a better understanding of the visual processing during the perception of 3D faces and the cognitive processing of considered important social stimuli. The fundamental question of this study aims to disentangle how is the perception of faces and facial cues integrated in the social cognition network to extract information regarding trustworthiness, a dimension which of most importance during social interactions. Other question is related to the role of the amygdala in dynamic face processing, (namely, facial characteristics such as the eye gaze) and reward expectations, since the amygdala has been implicated not only in processes regarding high-level decision-making responses to complex visual stimuli, but also in processes involved in reward expectations. Furthermore, this project seeks to understand the neural correlates of face perception when facial signals, more precisely gaze direction, are used as social attention cues to other human agents. To achieve the goals above presented, and in order to understand the neural bases of face processing (e.g. amygdala response), functional Magnetic Resonance Imaging (fMRI) was used. Participants interacted in a real-time social interaction known as the Trust Game. Results here presented reveal amygdala involvement for faces presenting Directed rather than Averted gaze. Also, middle frontal frontal gyrus, precentral gyrus and left superior temporal gyrus were shown to be involved in reward expectation processes. If eye gaze is able to influence trustworthiness judgements, this can be of a major impact, especially if the amygdala is involved in the extraction of this type of information from social interactions.
The processing of biologically plausible and implausible forms in American Sign Language: evidence for perceptual tuning

ABSTRACT The human auditory system distinguishes speech-like information from general auditory signals in a remarkably fast and efficient way. Combining psychophysics and neurophysiology (MEG), we demonstrate a similar result for the processing of visual information used for language communication in users of sign languages. We demonstrate that the earliest visual cortical responses in deaf signers viewing American Sign Language signs show specific modulations to violations of anatomic constraints that would make the sign either possible or impossible to articulate. These neural data are accompanied with a significantly increased perceptual sensitivity to the anatomical incongruity. The differential effects in the early visual evoked potentials arguably reflect an expectation-driven assessment of somatic representational integrity, suggesting that language experience and/or auditory deprivation may shape the neuronal mechanisms underlying the analysis of complex human form. The data demonstrate that the perceptual tuning that underlies the discrimination of language and non-language information is not limited to spoken languages but extends to languages expressed in the visual modality.
