Soft-computing based digital filter design to analyze vibration signals of induction motor

Extensive amount of detection and analysis of healthy working circumstance of Induction Motors (IM) are proposed and implemented in literature. This paper considers, heuristic approach assisted adaptive filter is recommended to detect and analyze the vibration signal of IM. In this work, a digital Infinite Impulse Response (IIR) filter is designed using recent heuristic algorithm known as the Firefly Algorithm (FA). During this study, a model squirrel-cage induction motor running at various load conditions, such as 25%, 50%, 75% and 100% are considered and the variation of the vibration level with respect to the variation in load is analyzed using the proposed procedure. The performance of the FA based IIR filter (FA-IIRF) is then validated against the IIR filter designed using PSO and BA based approaches. This experimental study confirms the capability of FA-IIRF in detecting the common induction motor faults like, vibration due to weak bearing and vibration due to the stator winding. Finally, the statistical significance of the FA-IIRF is confirmed using the Wilcoxon's rank-sum test. This test also proves that, FA based approach is better than PSO and BA based approach.
A theory of the detection and learning of structured representations of similarity and relative magnitude

Responding to similarity, difference, and relative magnitude is ubiquitous in the animal kingdom. However, humans seem unique in the ability to represent relative magnitude and similarity as abstract relations that take arguments (e.g., greater-than ( x , y )). While many models use structured relational representations of magnitude and similarity, little progress has been made on how these representations arise. Models that use these representations assume access to computations of similarity and magnitude a priori. We detail a mechanism for producing invariant responses to “same”, “different”, “more”, and “less” which can be exploited to compute similarity and magnitude as an evaluation operator. Using DORA (Doumas, Hummel, & Sandhofer, 2008), these invariant responses can serve to learn structured relational representations of relative magnitude and similarity from pixel images of simple shapes.
Deterministic high-speed root-hashing automaton matching coprocessor for embedded network processor

While string matching plays an important role in deep packet inspection applications, its software algorithms are insufficient to meet the demands of high-speed performance. Accordingly, we were motivated to propose fast and deterministic performance root-hashing automaton matching (RHAM) coprocessor for embedded network processor. Although automaton algorithms are robust with deterministic matching time, there is still plenty of room for improvement of their average-case performance. The proposed RHAM employs novel root-hashing technique to accelerate automaton matching. In our experiment, RHAM is implemented in a prevalent automaton algorithm, Aho-Corasick (AC) which is often used in many packet inspection applications. Compared to the original AC, RHAM only requires extra vector size in 48 Kbytes for root-hashing, and has about 900% and 420% outperformance for 20,000 URLs and 10,000 virus patterns respectively. Implementaion of RHAM FPGA can perform at the rate of 12.6 Gbps with the pattern amount in 34,215 bytes. This is superior to all previous matching hardware in terms of throughput and pattern set.
Trajectory modeling based on HMMs with the explicit relationship between static and dynamic features

This paper shows that the HMM whose state output vector includes static and dynamic feature parameters can be reformulated as a trajectory model by imposing the explicit relationship between the static and dynamic features. The derived model, named trajectory HMM, can alleviate the limitations of HMMs: i) constant statistics within an HMM state and ii) independence assumption of state output probabilities. We also derive a Viterbi-type training algorithm for the trajectory HMM. A preliminary speech recognition experiment based on N -best rescoring demonstrates that the training algorithm can improve the recognition performance significantly even though the trajectory HMM has the same parameterization as the standard HMM.
The relationship between a location of visual stimulus and SSVEP

Brain Computer Interface (BCI) is useful as an interface to operate a computer and external equipment using brain activities. A Steady-State Visual Evoked Potential (SSVEP) is known as the powerful tool to achieve BCI systems. A user of BCI focuses on the visual stimulus which produces brain activities used as an input of BCI. On the other hand, the user needs to pay own attention to surrounding situation for avoiding accidents. This means that the user should turn own attention to both the environment and the visual stimulus. The practical SSVEP based BCI often places visual stimuli around a fixation point which displays the surrounding situation captured by a camera. In addition, the visual stimulus equipped with moving vehicles has a slight movement due to our body movement and vehicle movement. This fact shows that the visual stimulus is moving at the side of user's vision. However, the relation of a SSVEP and a place and moving of visual stimulus has not been discussed. In this paper, we measure and analyze SSVEP for visual stimulus located on the surrounding area of fixation point, and a moving visual stimulus.
On Formal Models for Secure Key Exchange

A new formal security model for session key exchange protocols in the public key setting is proposed, and several eecient protocols are analyzed in this model. The relationship between this new model and previously proposed models is explored, and several interesting, subtle distinctions between static and adaptive adversaries are explored. We also give a brief account of anonymous users.
Is the librarian a distinct personality type?

A critical assessment is made of psychological investigations into the personality of the librarian conducted over the last 30 years. The influence of societal stereotypes upon psychological research is examined. Problematic methodologies and conflicting results preclude the emergence of any distinct personality profile common to librarians. The studies fail to demonstrate links between the individual and the organization. The efficacy of the whole psychological enterprise is brought into question
Multifeature analysis of Gd‐enhanced MR images of breast lesions

The objective of this study was to determine whether linear discriminant analysis of different independent features of MR images of breast lesions can increase the sensitivity and specificity of this technique. For MR images of 23 benign and 20 malignant breast lesions, three independent classes of features, including characteristics of Gd‐DTPA‐uptake curve, boundary, and texture were evaluated. The three classes included five, four and eight features each, respectively. Discriminant analysis was applied both within and across the three classes, to find the best combination of features yielding the highest classification accuracy. The highest specificity and sensitivity of the different classes considered independently were as follows: Gd‐up‐take curves, 83% and 70%; boundary features, 86% and 70%; and texture, 70% and 75%, respectively. A combination of one feature each from the first two classes and age yielded a specificity of 79% and sensitivity of 90%, whereas highest figures of 93% and 95%, respectively, were obtained when a total of 10 features were combined across different classes. Statistical analysis of different independent classes of features in MR images of breast lesions can improve the classification accuracy of this technique significantly.
Cultural Differences in Perceptions of Allocators of Resources

It was hypothesized that people draw different dispositional inferences about decision makers who allocate resources according to equity, equality, or need and that this difference varies depending on culture and whether the allocation is positive or negative. Results from college students in the United States and Germany revealed the following. First, reactions to allocators form two clusters: intelligent/strong/logical and warm/nice. Second, when giving a positive resource, American allocators are in a real dilemma: If they give on the basis of merit, they are rated high on the first cluster but low on the second; if they favor the needy, reactions reverse. No such dilemma exists for German allocators or in negative allocation situations where everyone approves of a need allocation. Third, Americans evaluate equality allocators quite highly, especially in the negative allocation condition. Fourth, allocators who have bonuses to distribute are evaluated more positively-another example of the fundamental attribution error.
ADAPTATION AND INTRAINDIVIDUAL VARIATION IN SALES OUTCOMES: EXPLORING THE INTERACTIVE EFFECTS OF PERSONALITY AND ENVIRONMENTAL OPPORTUNITY

Many practices in the field of industrial-organizational psychology assume that individual performance is stable across time; yet, little is actually known about the extent to which performance varies within individuals. We specifically address this issue by exploring the longitudinal influence of a situational opportunity (referrals received from the central office) on intraindividual performance outcomes of sales representatives. We also explore conscientiousness and openness to experience as traits that explain variation in adaptation to changes in referrals. Our results show that more weekly variation in individual performance resides within individuals than between individuals. A majority of this variance is explained by the situational opportunity of referrals. Further, the positive relationship between referrals and outcomes is stronger for sales representatives high on conscientiousness, but weaker for representatives high on openness to experience.
PARTNERS IN PRETEND PLAY: ASSOCIATIONS WITH FAMILY AND PEER EXPERIENCE IN EARLY DEVELOPMENT

This study investigated associations between family and peer experience and individual differences in children's social and solitary pretend play in early childhood. Participants included 655 children (330 male) and their mothers from the NICHD Study of Early Child Care. At 15, 24, and 36 months of age, children's solitary pretend play during a free play task and the mother-child relationship during a semi-structured play task were observed and coded. Children's social pretend play with an age- and gender-matched, familiar peer was observed during semi-structured play at 36 months. Results from hierarchical regression analyses supported the following predictive relations: 1) frequency and quality of children's solitary pretense was best predicted by children's cognitive competence at 15 months, by intrusive and insensitive maternal engagement in play at 24 months, and by peer experience in child care at 36 months; 2) children's social pretend complexity with a peer at 36 months was predicted by early positive-mother-child play, peer experience in child care, a positive relationship with a same-aged or older peer, and pretend-agent behaviors during solitary pretense. These results suggest that although children's solitary and social pretend play are related, the development of social and solitary pretense is differentially predicted by children's social experience with family and peers.
Projection of Own on Others' Job Characteristics: Evidence for the False Consensus Effect in Job Characteristics Information

The present study is an examination of the influence of rater characteristics as a source of bias in job characteristics information, as gleaned from the Job Diagnostic Survey (JDS). Participants (N=133) completed an initial JDS for own job characteristics. Non-incumbents (n=104) then completed a secondary JDS in order to rate incumbents' job characteristics. Non-incumbents' personality dimensions, own job characteristics, job satisfaction level, and incumbent satisfaction level were hypothesized as predictors of ratings of job characteristics of incumbents. Results indicate that two characteristics, job autonomy and dealing with others, were influenced by non-incumbents standing on these characteristics, and demonstrated evidence of the false consensus effect. Limitations and implications for interpreting job information are discussed.
The Swiss “Tina Fey Effect”: The Content of Late-Night Political Humor and the Negative Effects of Political Parody on the Evaluation of Politicians

This article investigates the content and effects of political humor on late-night television. Besides conducting a systematic content analysis of a Swiss late-night show, this article examines the effects of late-night political parody on competence evaluations of politicians. An experiment manipulated the televised parody of a politician and measured political knowledge. Results show that exposure to a televised political parody decreased competence ratings of politicians only for individuals high in political knowledge. The reason is that viewers must already have an understanding of current political affairs to “get the joke”—that is, the implicit message transported by the parody. The implications of such a negative “Tina Fey Effect” are discussed.
Current trends in electroencephalography

Several recent articles re-emphasize the value of clinical electrophysiology: in localizing epileptogenesis, predicting effectiveness of epilepsy surgery, and disclosing a mechanism of benign Rolandic epilepsy of childhood. A review of the role of EEG in the diagnosis of epilepsy indicated that epileptiform activity will appear in 50% of initial awake recordings of adults with epilepsy and in 85% of subjects undergoing two recordings. This contrasts with the appearance of spikes in only 4 of 1000 normal persons. Several studies focused on the value of electroencephalography in extratemporal epilepsy: 62% of patients with neocortical epilepsy had at least one localizing ictal EEG; occipital and temporal neocortical seizures were localized in a greater proportion than frontal or parietal attacks. Interictal spikes, if unifocal, always arose from the epileptogenic region in a study of their seizure localizing value. Such congruence augured for better seizure control by focal resection in two studies reviewed herein. Studies indicating the value of interictal temporal lobe spikes and scalp-recorded seizures in lateralising a temporal seizure focus are reviewed. One study found EEG to be slightly more reliable for lateralization of temporal epileptogenesis than MRI. In patients with benign Rolandic seizures, enhanced motor evoked potentials (MEPs) were obtained from transcranial magnetic stimulation when this was applied 50-80 msec after electrical stimulation of the thumb whereas this interval inhibited the MEP in normal subjects. This suggests that afferent cutaneous input abnormally and synchronously activates a large population of sensory neurons; such activation is subsequently transmitted to the motor cortex to produce the focal spikes in this condition. Finally, advances in non-invasive technology have redefined and limited the need for invasive monitoring in children with intractable seizure disorders.
The effect of rate of antidepressant tapering on the incidence of discontinuation symptoms: a randomised study

Twenty eight patients treated with selective serotonin reuptake inhibitors /venlafaxine were randomized to a three-day (short) or 14-day (longer) anti—depressant taper and openly assessed after a five to seven day drug-free washout, and again after seven days treatment with a new anti—depressant of the treating clinician's choice. A 'discontinuation syndrome' ( ≥ 3 new symptoms on the Discontinuation Emergent Signs and Symptoms checklist) occurred in 46% of patients with a similar frequency in those with short (7/15) versus longer (6/13) taper. Patients initially on short half-life anti—depressants had significantly greater increases in discontinuation and depressive symptoms than those stopping fluoxetine. Four patients, all on paroxetine, developed emergent suicidal ideation after taper. These results support the importance of half-life in determining discontinuation symptoms and suggest that there is little advantage to a two-week taper over a three-day taper when switching antidepressants. Antidepressant discontinuation in depressed patients can be associated with worsening depression and increased suicidality.
The Early Communication Indicator for Infants and Toddlers

The Early Communication Indicator (ECI) is a measure relevant to intervention decision making and progress monitoring for infants and toddlers. With increasing recognition of the importance of quality early childhood education and intervention for all children, measurement plays an important role in documenting children’s progress and outcomes of early educational experiences. Screening and progress-monitoring measures used in a response-to-intervention approach require age-based benchmarks for decision-making support. The goal of this study was to create a normative sample of ECI data referenced to children served by Early Head Start, including children with Individualized Family Service Plans (IFSPs). In a large sample of children (N = 5,883), program staff in 27 Early Head Start programs in two states collected ECI data from 2002 to 2007. Results indicated that children’s ECI total communication growth was conditional on IFSP status but not on gender or home language (English versus Spanish). Children’s patterns of communication on the ECI key skill elements (i.e., gestures, vocalizations, single words, and multiple words) were also conditional on IFSP status. Children with IFSPs had (a) later ages of onset for vocalizations, single words, and multiple words; (b) generally slower growth over time; and (c) significantly lower mean levels in the most advanced key skill: multiple words at 36 months of age. Implications for early childhood researchers and service providers are discussed.
Electro-optic synthesis of 8PSK by quad-parallel Mach-Zehnder modulator

We propose a method to synthesize optical 8PSK with linear phasor trajectory by using a quad-parallel Mach-Zehnder modulator, where BPSK signals are linearly superposed to form 8PSK. Modulation and demodulation of 30-Gb/s 8PSK are demonstrated.
Students' Perceptions of Success in the Online Graduate-Level Classes: A Self-Directed Learning Perspective.

The purpose of this study is to examine the phenomenon of successful online learning, defined as a higher academic performance (A or 90) and to find if there is the evidence to confirm the role of self-directed learning in the online graduate-level courses. A qualitative method was used to analyze learners perceptions of online learning experiences. Six graduate students from an American public university participated in this study. The qualitative analysis yielded six major themes, which confirm the relationship between self-directed learning and academic performance.
Introduction to the special issue: Emotional states, attention, and working memory

This special issue is concerned with the effects of various emotional states on attention, working memory and performance. We focus on two negative emotional states (anxiety and depression) and on positive affect generally. The main aims of the current paper are to highlight the contributions of the special issue on the mechanisms by which negative and positive emotions influence the critical processes involved in attention, working memory and cognitive performance. The paper starts with an overview of some of the early as well as more recent theoretical developments, discussing the effects of emotional states on specific executive processes in working memory, including the mediating role of these cognitive mechanisms in task performance. The paper will then consider separately the effects of anxiety, depression, and positive emotions on cognitive performance before it identifies the similarities and differences in the effects of these emotional states on attention and working memory. Finally, the paper highlights a number of important implications from the special issue contributions in identifying promising routes for future progression and development. In order to understand why we decided that it was timely to have a special issue devoted to this topic, it is necessary to consider briefly some of the relevant historical context. During much of the twentieth century, there was more research on the effects of anxiety than on those of either depression or positive affect. Part of the impetus for this research was the consistent finding that high levels of test anxiety (a dimension of individual differences relating to fear and apprehension of test taking) is negatively correlated with academic performance. For example, Hembree (1988) conducted a comprehensive review of hundreds of studies, and found that the mean correlation between test anxiety and academic achievement or aptitude was . 29. Of course, this is only correlational evidence, and so the direction of causality is unclear. The causality issue was addressed by Schwarzer (1990), who reviewed the findings from over one hundred intervention studies. The overall finding that individuals who received treatment for test anxiety had higher scores on test performance and grade point average than did those in placebo or
Synergistic antitumor activity of histone deacetylase inhibitors and anti-ErbB3 antibody in NSCLC primary cultures via modulation of ErbB receptors expression

ErbB3, a member of the ErbB family receptors, has a key role in the development and progression of several cancers, including non-small cell lung cancer (NSCLC), and in the establishment of resistance to therapies, leading to the development of anti-ErbB3 therapies. In this study we demonstrated, in a set of malignant pleural effusion-derived cultures of NSCLC, the synergistic antitumor effect of a histone deacetylase inhibitor (HDACi), such as vorinostat or valproic acid (VPA), in combination with the anti-ErbB3 monoclonal antibody (MoAb) A3. Synergistic interaction was observed in 2D and in 3D cultures conditions, both in fully epithelial cells expressing all ErbB receptors, and in cells that had undergone epithelial to mesenchymal transition and expressed low levels of ErbB3. We provided evidences suggesting that differential modulation of ErbB receptors by vorinostat or VPA, also at low doses corresponding to plasma levels easily reached in treated patients, is responsible for the observed synergism. In details, we showed in epithelial cells that both vorinostat and VPA induced time- and dose-dependent down-regulation of all three ErbB receptors and of downstream signaling. On the contrary, in A3-resistant mesenchymal cells, we observed time- and dose-dependent increase of mRNA and protein levels as well as surface expression of ErbB3, paralleled by down-regulation of EGFR and ErbB2. Our results suggest that the combination of a HDACi plus an anti-ErbB3 MoAb represents a viable strategy that warrants further evaluation for the treatment of NSCLC patients.
