    Four studies tested the hypothesis that the emotion of benign envy, but not the emotions of admiration or malicious envy, motivates people to improve themselves. Studies 1 to 3 found that only benign envy was related to the motivation to study more (Study 1) and to actual performance on the Remote Associates Task (which measures intelligence and creativity; Studies 2 and 3). Study 4 found that an upward social comparison triggered benign envy and subsequent better performance only when people thought self-improvement was attainable. When participants thought self-improvement was hard, an upward social comparison led to more admiration and no motivation to do better. Implications of these findings for theories of social emotions such as envy, social comparisons, and for understanding the influence of role models are discussed.

    Previous research has yielded inconsistent findings concerning the relationship between envy and schadenfreude. Three studies examined whether the distinction between benign and malicious envy can resolve this inconsistency. We found that malicious envy is related to schadenfreude, while benign envy is not. This result held both in the Netherlands where benign and malicious envy are indicated by separate words (Study 1: Sample A, N = 139; Sample B, N = 150), and in the USA where a single word is used to denote both types (Study 2, N = 180; Study 3, N = 349). Moreover, the effect of malicious envy on schadenfreude was independent of other antecedents of schadenfreude (such as feelings of inferiority, disliking the target person, anger, and perceived deservedness). These findings improve our understanding of the antecedents of schadenfreude and help reconcile seemingly contradictory findings on the relationship between envy and schadenfreude.

    The aim of this study was to examine the relationship between individual attributes and envy, and to determine how envy may impact personal response variables in the workplace. To address these issues we apply Vecchio's theory on antecedents and consequences of envy (1995) as a theoretical framework. The present study relied on a cross-sectional measurement design. A total of 135 leaders and 772 followers employed in business organizations participated. SEM analysis shows that span of supervision serves as an important antecedent of envy, where span of supervision is significantly associated to envy via supportive leadership. Furthermore, envy seems to be indirectly and negatively related to self-esteem via distress and directly related to social loafing. The implications of these findings are discussed, and suggestions for future research are outlined.

    Envy is a frustrating emotion that arises from upward social comparison. Two studies investigated the appraisals that distinguish benign envy (aimed at improving one’s own situation) from malicious envy (aimed at pulling down the superior other). Study 1 found that appraisals of deservingness and control potential differentiated both types of envy. We manipulated these appraisals in Study 2 and found that while both did not influence the intensity of envy, they did determine the type of envy ...

    In this article, we test psychodynamic assumptions about envy and narcissism by examining malicious envy in the context of narcissistic grandiosity and vulnerability. In Study 1, students (N = 192) and community adults (N = 161) completed trait measures of narcissism, envy, and schadenfreude. In Study 2 (N = 121), participants relived an episode of envy, and cognitive-affective components of envy were examined in the context of both self- and informant reports of their envy and narcissism. In Study 3 (N = 69), narcissism was linked to reports of envy covertly induced in the laboratory. Vulnerable narcissism was strongly and consistently related to dispositional envy and schadenfreude (Studies 1-2), as well as to all cognitive-affective components of envy (Study 2). Furthermore, it facilitated envy and schadenfreude toward a high-status peer (Study 3). Grandiose narcissism was slightly negatively related to dispositional envy (Studies 1-2), and it did not predict informant reports of envy or cognitive-affective components of the emotion (Study 2). Finally, it did not exacerbate envy, hostility, or resentment toward a high-status peer (Study 3). The results suggest envy is a central emotion in the lives of those with narcissistic vulnerability and imply that envy should be reconsidered as a symptom accompanying grandiose features in the diagnosis of narcissistic personality disorder. © 2012 The Authors.

    Envy is a frustrating emotion that arises from upward social comparison. Two studies investigated the appraisals that distinguish benign envy (aimed at improving one's own situation) from malicious envy (aimed at pulling down the superior other). Study 1 found that appraisals of deservingness and control potential differentiated both types of envy. We manipulated these appraisals in Study 2 and found that while both did not influence the intensity of envy, they did determine the type of envy that resulted. The more a situation was appraised as undeserved, the more participants experienced malicious envy. Benign envy was experienced more when the situation was not undeserved, and the most when the situation was appraised as both deserved and controllable. The current research also clarifies how the types of envy differ from the related emotions admiration and resentment.

  10. Elucidating the Dark Side of Envy: Distinctive Links of Benign and Malicious Envy With Dark Personalities

    Lange, Jens; Paulhus, Delroy L.; Crusius, Jan

    2017-01-01

    Researchers have recently drawn a contrast between two forms of envy: benign and malicious envy. In three studies (total N = 3,123), we challenge the assumption that malicious envy is destructive, whereas benign envy is entirely constructive. Instead, both forms have links with the Dark Triad of personality. Benign envy is associated with Machiavellian behaviors, whereas malicious envy is associated with both Machiavellian and psychopathic behaviors. In Study 1, this pattern emerged from meta-analyzed trait correlations. In Study 2, a manipulation affecting the envy forms mediated an effect on antisocial behavioral intentions. Study 3 replicated these patterns by linking envy to specific antisocial behaviors and their impact on status in the workplace. Together, our correlational and experimental results suggest that the two forms of envy can both be malevolent. Instead of evaluating envy’s morality, we propose to focus on its functional value.

  11. Burning With Envy? Dispositional and Situational Influences on Envy in Grandiose and Vulnerable Narcissism.

    Research on narcissism and envy suggests a variable relationship that may reflect differences between how vulnerable and grandiose narcissism relate to precursors of envy. Accordingly, we proposed a model in which dispositional envy and relative deprivation differentially mediate envy's association with narcissistic vulnerability, grandiosity, and entitlement. To test the model, 330 young adults completed dispositional measures of narcissism, entitlement, and envy; one week later, participants reported on deprivation and envy feelings toward a peer who outperformed others on an intelligence test for a cash prize (Study 1) or earned higher monetary payouts in a betting game (Study 2). In both studies, structural equation modeling broadly supported the proposed model. Vulnerable narcissism robustly predicted episodic envy via dispositional envy. Entitlement-a narcissistic facet common to grandiosity and vulnerability-was a significant indirect predictor via relative deprivation. Study 2 also found that (a) the grandiose leadership/authority facet indirectly curbed envy feelings via dispositional envy, and (b) episodic envy contributed to schadenfreude feelings, which promoted efforts to sabotage a successful rival. Whereas vulnerable narcissists appear dispositionally envy-prone, grandiose narcissists may be dispositionally protected. Both, however, are susceptible to envy through entitlement when relative deprivation is encountered. © 2015 Wiley Periodicals, Inc.

  14. Dispositional envy revisited: unraveling the motivational dynamics of benign and malicious envy.

    Lange, Jens; Crusius, Jan

    2015-02-01

    Previous research has conceptualized dispositional envy as a unitary construct. Recently however, episodic envy has been shown to emerge in two qualitatively different forms. Benign envy is related to the motivation to move upward, whereas malicious envy is related to pulling superior others down. In four studies (N = 1,094)--using the newly developed Benign and Malicious Envy Scale (BeMaS)--we show that dispositional envy is also characterized by two independent dimensions related to distinct motivational dynamics and behavioral consequences. Dispositional benign and malicious envy uniquely predict envious responding following upward social comparisons. Furthermore, they are differentially connected to hope for success and fear of failure. Corresponding to these links, dispositional benign envy predicted faster race performance of marathon runners mediated via higher goal setting. In contrast, dispositional malicious envy predicted race goal disengagement. The findings highlight that disentangling the two sides of envy opens up numerous research avenues. © 2014 by the Society for Personality and Social Psychology, Inc.

  15. Enterprise Potential, Entrepreneurial Intentions and Envy

    Full Text Available This paper presents the results of research about the impact of envy on enterprise potential and entrepreneurial intentions. The research was conducted in Serbia and the respondents were students from 5 faculties, from the first to the fifth year of study. The results were gained by statistical analysis of the gathered information (380 completed questionnaires. Descriptive, correlation and regression analysis are the methods of statistical analysis that were used. From the dimensions of enterprise potential, the highest average value has the dimension Creativity, while from the dimensions of entrepreneurial intentions, the highest average value has the dimension Subjective norm. Of all the observed dimensions, the lowest value has the Envy dimension. Between envy and dimensions of enterprise potential and dimensions of entrepreneurial intentions, there are a number of statistically significant negative correlations. This is more prevalent at the dimension of entrepreneurial intentions. Feelings of inferiority in relation to other people and the perception of having a boring or a bad life have an especially negative impact on entrepreneurial potential and intentions. Envy, which occurs due to the desire for more entertainment, travel, and due to the perception of the lack of fortune, also has a negative impact on entrepreneurial potential and intentions, but the influence is considerably weaker. There is a statistically significant predictive effect of certain items of envy on enterprise potential dimensions and entrepreneurial intentions dimensions. But this fact is not so strongly expressed. Some results suggest the possibility (however small that envy, in some circumstances, can mildly encourage entrepreneurial intention.

    Gratitude has been investigated in various areas in psychology. The present research showed that gratitude had some positive effects on some aspects of our life, such as subjective well-being, life satisfaction, and social relationships. It can also help us relieve negative emotions. However, the existing literature has not studied the influence of gratitude on envy. The present study used structural equation modeling to test the mediating role of social support between gratitude and two types of envy (malicious and benign). We recruited 426 Chinese undergraduates to complete the Gratitude Questionnaire, Malicious and Benign Envy Scales, and the Multi-Dimensional Scale of Perceived Social Support. Results showed that gratitude positively predicted benign envy and negatively predicted malicious envy. In addition, the indirect effect of gratitude on two types of envy via social support was significant. These results revealed the direct relationship between gratitude and malicious/benign envy, and the mediating effect of social support, which will contribute to find effective measures to inhibit malicious envy and promote benign envy from the perspective of cultivating gratitude and increasing individuals' social support.

  3. The painful duality of envy: Evidence for an integrative theory and a meta-analysis on the relation of envy and schadenfreude.

    Lange, Jens; Weidman, Aaron C; Crusius, Jan

    2018-04-01

    Despite envy's importance as a driver of social behavior, scholars disagree on its conceptualization. We review the literature and distinguish three incongruent theories: (a) Malicious Envy Theory (i.e., envy as uniform and malicious), (b) Dual Envy Theory (i.e., envy as taking on 2 forms, benign and malicious), and (c) Pain Theory of Envy (i.e., envy as uniform and driven by pain). Moreover, within and across theories, operationalizations of envy have included various different components. We integrate these conceptualizations using a data-driven approach, deriving a comprehensive theory of envy in 5 studies (total N = 1,237)-the Pain-driven Dual Envy (PaDE) Theory. Exploratory and confirmatory factor analyses of an exhaustive set of envy components (Studies 1-4) suggest that envy consists of 3 factors: Pain (i.e., preoccupation with the envy-eliciting situation, inferiority), predicts both benign envy (i.e., desire for the envy object, improvement motivation, emulation of the other), and malicious envy (i.e., communication about the other, directed aggression, nondirected aggression). An experience-sampling study (Study 5) suggests that pain constitutes a quickly fading reaction, whereas benign and malicious envy are enduring attitudinal constructs. We apply this theory in a meta-analysis on the controversial relation of envy and schadenfreude (N = 4,366), finding that envy and schadenfreude are more strongly and positively correlated to the extent that the respective research operationalizes envy as malicious, compared with as pain or benign envy. We discuss how the PaDE Theory can illuminate research on envy in diverse settings, and envy's relation to other distinct emotions. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Two key emotions people can experience when someone else is better than them are envy and admiration. There are conflicting findings in the scientific literature on which behaviour is elicited by these emotions. In one study (with two samples, total N = 345), we test which motivations are triggered by envy and admiration. The main finding is that (benign) envy and admiration both lead to a motivation to improve oneself. This confirms earlier findings that admiration leads to a motivation to affiliate with the admired other and a motivation to improve one's own position. Furthermore, it supports the idea that envy can lead to both a motivation to improve oneself and a motivation to pull down the envied other, finding support for a subtypes theory of envy.

    In literature, envy has long been written of as one of the seven cardinal sins. In biblical mythology, envy as a consequence of vanity can be understood to be the reason for archangel Lucifer's fall from a state of heavenly grace and unionship. Freud was the first psychoanalytic theorist to introduce the idea of envy, albeit through his controversial concept of penis envy. Karl Abrahams and Melanie Klein later placed envy at the crucial developing stages of the relationship between primary caregiver and infant. Klein boldly identified envy as a primary constitutional emotion. However, the presence and difficulties of envy in clinical work remain largely underreported, more so in work with children. This paper asks whether an attachment base can be secure if envy is dominant. The analysis of a nine-year-old girl ('Kirsten') and her envious transference with her therapist will be examined, to explore the relationship between envy and attachment security. While contemporary research focuses on developing attachment theory in relation to specific psychiatric conditions, this paper will discuss affect as the binding link or disruptive force between self and object representations, that then determine attachment security.

    On Facebook, users are exposed to posts from both strong and weak ties. Even though several studies have examined the emotional consequences of using Facebook, less attention has been paid to the role of tie strength. This paper aims to explore the emotional outcomes of reading a post on Facebook and examine the role of tie strength in predicting happiness and envy. Two studies - one correlational, based on a sample of 207 American participants and the other experimental, based on a sample of 194 German participants - were conducted in 2014. In Study 2, envy was further distinguished into benign and malicious envy. Based on a multi-method approach, the results showed that positive emotions are more prevalent than negative emotions while browsing Facebook. Moreover, tie strength is positively associated with the feeling of happiness and benign envy, whereas malicious envy is independent of tie strength after reading a (positive) post on Facebook.

    2016-07-01

    To discuss envy and jealousy and how their positive and negative aspects among nurse academics affect the workplace. In nursing academia, jealousy and envy are common emotions, engendered by demands for high productivity, intense competition for limited resources, preferences for particular assignments and opportunities for promotions. When these feelings are moderate and part of everyday rivalry, competition and ambition benefit the organisation. However, jealousy and envy can have serious consequences including damaged relationships and communication, and the undermining of colleagues' performance. Strategies are recommended to provide opportunities for self-reflection and consideration of how the workplace affects nursing academics' wellbeing and professional performance. Jealousy and envy can be damaging emotions in the workplace. The embittered, hostile person can undermine and damage relationships, disrupt teams and communication, and undermine organisational performance. Discussing the positive and negative effects of envy and jealousy provides an opportunity for nursing academics to self-reflect and to consider others and their own personal and professional performance. Understanding how jealousy and envy impact on the work environment, workplace relationships and individual/team performance is important especially for early career and seasoned nursing academics alike.

    The old dogma has always been that the most complex aspects of human emotions are driven by culture; Germans and English are thought to be straight-laced whereas Italians and Indians are effusive. Yet in the last two decades there has been a growing realization that even though culture plays a major role in the final expression of human nature, there must be a basic scaffolding specified by genes. While this is recognized to be true for simple emotions like anger, fear, and joy, the relevance of evolutionary arguments for more complex nuances of emotion have been inadequately explored. In this paper, we consider envy or jealousy as an example; the feeling evoked when someone is better off than you. Our approach is broadly consistent with traditional evolutionary psychology (EP) approaches, but takes it further by exploring the complexity and functional logic of the emotion – and the precise social triggers that elicit them – by using deliberately farfetched, and contrived “thought experiments” that the subject is asked to participate in. When common sense (e.g., we should be jealous of Bill Gates – not of our slightly richer neighbor) appears to contradict observed behavior (i.e., we are more envious of our neighbor) the paradox can often be resolved by evolutionary considerations which h predict the latter. Many – but not all – EP approaches fail because evolution and common sense do not make contradictory predictions. Finally, we briefly raise the possibility that gaining deeper insight into the evolutionary origins of certain undesirable emotions or behaviors can help shake them off, and may therefore have therapeutic utility. Such an approach would complement current therapies (such as cognitive behavior therapies, psychoanalysis, psychopharmacologies, and hypnotherapy), rather than negate them. PMID:28970815

    Humans have a strong social tendency to compare themselves with others. We tend to feel envious when we receive less valuable rewards and may rejoice when our payoffs are more advantageous. Envy and schadenfreude (gloating over the other's misfortune) are social emotions widely agreed to be a symptom of the human social tendency to compare one's payoffs with those of others. Given the important social components of envy and gloating, we speculated that oxytocin may have a modulating effect on the intensity of these emotions. Fifty-six participants participated in this double-blind, placebo-controlled, within-subject study. Following the administration of oxytocin or a placebo, participants played a game of chance with another (fake) participant who either won more money (envy manipulation), lost more money (schadenfreude manipulation), or won/lost equal amounts of money. In comparison with the placebo, oxytocin increased the envy ratings during unequal monetary gain conditions involving relative loss (when the participant gained less money than another player). Oxytocin also increased the ratings of gloating during relative gain conditions (when the participant gained more money than the other player). By contrast, oxytocin had no effect on the emotional ratings following equal monetary gains nor did it affect general mood ratings. These results suggest that the oxytocinergic system is involved in modulating envy and gloating. Thus, contrary to the prevailing belief that this system is involved solely in positive prosocial behaviors, it probably plays a key role in a wider range of social emotion-related behaviors.

    Closed habitats intended for different purposes like confinement studies, life in extreme environments (Antarctica) and as simulation testbeds for complex closed life support systems have been built and achieved different degrees of closure. Those that were built in preparation of space missions oriented themselves on the need of a crew of astronauts during a long term mission in Space, on Mars or Moon. At DLR in Cologne, a modular approach is followed to build a closed environmental habitat for scientific and medical studies, the DLR-EnviHab. This modular structure of the EnviHab is designed to include humans as integral part in a bioregenerative life support system, and allows a step-wise realization of the project, ensuring useful results for a wide field of scientific research during each phase. The DLR-EnviHab provides a platform for international and interdisciplinary research and the development of innovative solutions for cultivation and habitation on Earth as well as for long term space or planetary missions. By the inclusion of humans as integral component of the system, medical research areas including physiological and psychological health and rehabilitation as well as environmental research and monitoring and modelling of coupled and controlled systems are addressed in EnviHab. Results of the research conducted in the individual and combined EnviHab modules will also contribute to most urgent issues like water(recycling) management, food management, pollution/waste management and atmosphere(air) management. In addition, EnviHab contributes to public education and outreach with the open visible and partly accessible structure, an exhibition and an explanatory module.

    The disposal facility of the spent nuclear fuel will be operated from 2051. This paper presents the ENVI code developed by GoldSim Software to simulate options for managing spent nuclear fuel (SNF) in South Korea. The ENVI is a simulator to allow decision-makers to assist to evaluate the performance for spent nuclear fuel management. The multiple options for managing the spent nuclear fuel including the storage and transportation are investigated into interim storage, permanent disposal in geological repositories and overseas and domestic reprocessing. The ENVI code uses the GoldSim software to simulate the logistics of the associated activities. The result by the ENVI model not only produces the total cost to compare among the multiple options but also predict the sizes and timings of different facilities required. In order to decide the policy for spent nuclear management this purpose of this paper is to draw the optimum management plan to solve the nuclear spent fuel issue in the economical aspects. This paper is focused on the development of the ENVI's logic and calculations to simulate four options(No Reprocessing, Overseas Reprocessing, Domestic Reprocessing, and Overseas and Domestic Reprocessing) for managing the spent nuclear fuel in South Korea. The time history of the spent nuclear fuel produced from both the existing and future NPP's can be predicted, based on the Goldsim software made available very user friendly model. The simulation result will be used to suggest the strategic plans for the spent nuclear fuel management.

    2009-06-01

    Envy is the painful emotion caused by the good fortune of others. This research empirically supports the distinction between two qualitatively different types of envy, namely benign and malicious envy. It reveals that the experience of benign envy leads to a moving-up motivation aimed at improving one's own position, whereas the experience of malicious envy leads to a pulling-down motivation aimed at damaging the position of the superior other. Study 1 used guided recall of the two envy types in a culture (the Netherlands) that has separate words for benign and malicious envy. Analyses of the experiential content of these emotions found the predicted differences. Study 2 and 3 used one sample from the United States and one from Spain, respectively, where a single word exists for both envy types. A latent class analysis based on the experiential content of envy confirmed the existence of separate experiences of benign and malicious envy in both these cultures as well. The authors discuss the implications of distinguishing the two envy types for theories of cooperation, group performance, and Schadenfreude.

  19. The tango of two deadly sins: The social-functional relation of envy and pride.

    Envy stems from a social comparison with a superior standard. Its 2 distinct forms are directed at changing this situation in different ways, either by becoming as successful as the envied person (in benign envy) or by lowering the envied person's advantage (in malicious envy). In essence, envy is thus a social phenomenon. Nevertheless, most previous research has focused on its underlying intrapersonal processes, overlooking envy's interpersonal core. In contrast, we show in 6 studies (N = 1,513) that envy and pride are intertwined in a social-functional relationship. Envy and pride often co-occur (Study 1) and pride displays enhance envious feelings (Studies 2 and 3). Specifically, authentic (success attributed to effort) and hubristic pride (success attributed to talent) modulate envious intentions and behavior toward their benign and malicious form (Study 2 to 6). This effect is mediated via liking, perceived prestige, and perceived dominance (Study 4). In accordance with a social-functional approach, the effects emerge only when authentic and hubristic pride are expressed by the superior person and not when the respective information about the superior person's feelings is simply available in the environment (Study 5). These effects are present when participants recall envy situations (Study 1), when they imagine being in a competitive situation (Studies 3, 4, and 5), or when envy is elicited in situ (Studies 2 and 6). Our findings show the value of studying envy as a social phenomenon and open up numerous avenues for research on envy at the interpersonal and intergroup level. (c) 2015 APA, all rights reserved).

  20. Warding off the evil eye: when the fear of being envied increases prosocial behavior.

    The fear of being envied makes people act prosocially, in an attempt to ward off the potentially destructive effects of envy. In three experiments, people who were in a superior position and could be envied were more likely than control participants to give time-consuming advice to a potentially envious person or to help a potentially envious person pick up erasers she had accidentally scattered. However, helping behavior increased only if envy was likely to be malicious rather than benign. People who were better off did not increase their helping behavior toward people in general, but increased their helping only toward the potentially envious. This finding is consistent with the idea that the better off act more prosocially as an appeasement strategy. The fear of being envied serves useful group functions, because it triggers prosocial behavior that is likely to dampen the potentially destructive effects of envy and simultaneously helps to improve the situation of people who are worse off.

    van de Ven, Niels; Zeelenberg, Marcel

    2015-01-01

    We examined whether counterfactual thinking influences the experience of envy. Counterfactual thinking refers to comparing the situation as it is to what it could have been, and these thought processes have been shown to lead to a variety of emotions. We predicted that for envy the counterfactual thought "it could have been me" would be important. In four studies we found a clear link between such counterfactual thoughts and the intensity of envy. Furthermore, Studies 3 and 4 revealed that a manipulation known to affect the extent of counterfactual thinking (the perception of being close to obtaining the desired outcome oneself), had an effect on the intensity of envy via counterfactual thoughts. This relationship between counterfactual thinking and the experience of envy allows for new predictions concerning situations under which envy is likely be more intense.

    2011-10-01

    In a series of 4 experiments, we provide evidence that--in addition to having an affective component--envy may also have important consequences for cognitive processing. Our first experiment (N = 69) demonstrated that individuals primed with envy better attended to and more accurately recalled information about fictitious peers than did a control group. Studies 2 (N = 187) and 3 (N = 65) conceptually replicated these results, demonstrating that envy elicited by targets predicts attention and later memory for information about them. We demonstrate that these effects cannot be accounted for by admiration or changes in negative affect or arousal elicited by the targets. Study 4 (N = 152) provides evidence that greater memory for envied--but not neutral--targets leads to diminished perseverance on a difficult anagram task. Findings demonstrate that envy may play an important role in attention and memory systems and deplete limited self-regulatory resources available for acts of volition. 2011 APA, all rights reserved

    In the current article the authors examined the impact of specific emotions on moral hypocrisy, the tendency among people to judge others more severely than they judge themselves. In two studies, they found that (a) anger increased moral hypocrisy, (b) guilt eliminated moral hypocrisy, and (c) envy reversed moral hypocrisy. In particular, these findings were observed in two domains. In Study 1, participants responded to moral dilemmas describing unethical behavior and rated how acceptable it would be if others engaged in the unethical behavior, or alternatively, if they themselves engaged in the unethical behavior. In Study 2, participants were asked how much they would like to donate to research on cancer, or alternatively, how much they think others should donate. The results demonstrate that specific emotions influence moral decision making, even when real money is at stake, and that emotions of the same valence have opposing effects on moral judgment.

Population of the study was the entire faculty members with associate or higher degree in the educational year of 2014-2015. In the qualitative stage 20 individuals (experts were selected to design the primary model and questionnaire, and to fit the model 316 faculty members were selected. In the qualitative section it was specified that influential variables on envy management in faculty members are health organizational climate, spiritual leadership, effective communication, job satisfaction and professional development of professors and approved, as well in the quantitative section findings showed that there is a significant relationship between effective variables so that in indirect analysis of effect of organizational climate on envy management, the variable of spiritual leadership via the variable of effective communication had little effect on envy management than variables of professional development and job satisfaction. It is concluded that university managers should provide conditions and backgrounds of envy management in the universities and enable professors for more effective roles without envy in the scientific climate of university to achieve in educational, research and servicing efficiency.

    Abstract The study of moral emotions (i.e. Schadenfreude and envy) is critical to understand the ecological complexity of everyday interactions between cognitive, affective, and social cognition processes. Most previous studies in this area have used correlational imaging techniques and framed Schadenfreude and envy as unified and monolithic emotional domains. Here, we profit from a relevant neurodegeneration model to disentangle the brain regions engaged in three dimensions of Schadenfreude and envy: deservingness, morality, and legality. We tested a group of patients with behavioural variant frontotemporal dementia (bvFTD), patients with Alzheimer’s disease, as a contrastive neurodegeneration model, and healthy controls on a novel task highlighting each of these dimensions in scenarios eliciting Schadenfreude and envy. Compared with the Alzheimer’s disease and control groups, patients with bvFTD obtained significantly higher scores on all dimensions for both emotions. Correlational analyses revealed an association between envy and Schadenfreude scores and greater deficits in social cognition, inhibitory control, and behaviour disturbances in bvFTD patients. Brain anatomy findings (restricted to bvFTD and controls) confirmed the partially dissociable nature of the moral emotions’ experiences and highlighted the importance of socio-moral brain areas in processing those emotions. In all subjects, an association emerged between Schadenfreude and the ventral striatum, and between envy and the anterior cingulate cortex. In addition, the results supported an association between scores for moral and legal transgression and the morphology of areas implicated in emotional appraisal, including the amygdala and the parahippocampus. By contrast, bvFTD patients exhibited a negative association between increased Schadenfreude and envy across dimensions and critical regions supporting social-value rewards and social-moral processes (dorsolateral prefrontal cortex, angular

    Zepf, Siegfried; Seel, Dietmar

    2016-06-01

    Going along with Laplanche's assumption that there is no endogenous sexuality, the authors discuss Freud's concepts of the female Oedipus complex and penis envy and some of its proposed alternatives. The female oedipal conflict turns out to be the outcome of a projective identification with the Oedipus complexes of the mother and father. In the context of the rivalry with the mother, penis envy refers to the maternal power over the father's penis that the daughter wants to have in herself, while, in the context of the rivalry with the father, penis envy arises from the jealousy of the father's penis that the daughter believes is necessary to have on herself in order to satisfy her mother. The authors conclude that in Freud's day such insights were already available, which might have culminated in the conceptualization they present in this paper.

    Humans often project their own beliefs, desires and emotions onto others, indicating an inherent egocentrism. In five studies we investigated the neurocognitive mechanisms underlying emotional egocentricity bias (EEB) and specifically an offline EEB, defined as the projection of one's own tendency to react with a certain emotional response pattern in a given situation onto other people. We used a competitive reaction time game associated with monetary gains and losses that allowed inducing feelings of envy and Schadenfreude. While we found evidence for the first hand experience of envy and Schadenfreude, we also observed an offline bias, that is participants on average projected feelings of envy and Schadenfreude when having to judge others. Importantly the extent of experienced and projected social emotions were highly correlated. This bias was observed when participants were both directly involved and also as an uninvolved party, suggesting the offline bias to be independent of the presently experienced emotion. Under increased time pressure however an online bias emerged whereby participants just projected their presently experienced emotions onto the other. Finally, we show that on the neural level shared neuronal networks underlie the offline EEB at least for envy. Thus, for envy, activity of the same part of anterior insula was sensitive to individual differences both in the experience and the projection of envy. These findings outline the set of circumstances leading to specific types of empathic attribution biases and show that individual differences in the experience of social emotions are predictive of the offline egocentricity bias both on a behavioral as well as a neural level. These data extend present models on the neurocognitive mechanisms of interpersonal understanding in the socio-affective domain. Copyright © 2014 Elsevier Inc. All rights reserved.

    2008-01-01

    Staged as a moral drama, Melanie Klein's Envy and Gratitude (1957) straddles two eras: one reflecting a simpler more concrete, historical method, and the other an approach of greater complexity, focused on the transferential moment. Embedded within the transference are the vicious circles of envy and punishment that are the hallmark of Klein's text. Punishment itself which is always punishment of both self and other, creates its own vicious circle, set in motion by a single act. In the sadomasochistic enactments that result, the moral force of Klein's categories fuels the countertransference. A detailed clinical hour is presented.

    Nearly 100 years ago, the philosopher and mathematician Bertrand Russell warned of the social dangers of widespread envy. One view of modern society is that it is systematically developing a set of institutions -- such as social media and new forms of advertising -- that make people feel inadequate and envious of others. If so, how might that be influencing the psychological health of our citizens? This paper reports the first large-scale longitudinal research into envy and its possible repercussions. The paper studies 18,000 randomly selected individuals over the years 2005, 2009, and 2013. Using measures of SF-36 mental health and psychological well-being, four main conclusions emerge. First, the young are especially susceptible. Levels of envy fall as people grow older. This longitudinal finding is consistent with a cross-sectional pattern noted recently by Nicole E. Henniger and Christine R. Harris, and with the theory of socioemotional regulation suggested by scholars such as Laura L. Carstensen. Second, using fixed-effects equations and prospective analysis, the analysis reveals that envy today is a powerful predictor of worse SF-36 mental health and well-being in the future. A change from the lowest to the highest level of envy, for example, is associated with a worsening of SF-36 mental health by approximately half a standard deviation (p < .001). Third, no evidence is found for the idea that envy acts as a useful motivator. Greater envy is associated with slower -- not higher -- growth of psychological well-being in the future. Nor is envy a predictor of later economic success. Fourth, the longitudinal decline of envy leaves unaltered a U-shaped age pattern of well-being from age 20 to age 70. These results are consistent with the idea that society should be concerned about institutions that stimulate large-scale envy. Copyright © 2018 Elsevier Ltd. All rights reserved.

I am specifically interested in how previous research explored the consequences of Facebook use on psychological outcomes, the moderating function of envy in the link between Facebook use and reduced affective wellbeing, the psychological results of non-interactive Facebook conduct, and the role of relationship closeness in anticipating user’s contentment and envy after inspecting a post. A synthesis of the extant literature suggests that inspecting other individuals’ positive news on Facebook brings about contentment through emotional contagion, whereas negative news causes discomfort as a consequence of mood contagion, the transmissible effect being more powerful when the news is associated with a strong tie. The outcomes of this research back the argument that self-confidence and dispositional envy are instrumental in producing Facebook envy. These findings highlight that the emotional results of browsing Facebook are considerably affected by the substance of the comment, the personal attributes of the Facebook

    number of players. The only existing finite envy-free cake cutting protocol for any number of players, designed by Brams and Taylor [4], has the property that its runtime can be made arbitrarily large by setting up the valuation functions of the players appropriately. Moreover, there is no closed formula...... that relates the valuation functions to the number of queries required by the protocol. In this note we show that when the valuations can be represented as polynomial functions, there exists a protocol in the standard query model that is much simpler conceptually and has a runtime bound depending...

  1. [Sibling relations from the family therapy perspective--support, attachment, rivalry and envy].

    Cierpka, M

    2001-01-01

    In family therapy, during the last years more and more importance is attached to the dynamics of the sibling subsystem. In the present paper differences between them as well as similarities are discussed from the point of view of family theory. Relevant dimensions like support, attachment, rivalry and envy between brothers and sisters contribute essentially to the family dynamics. In this clinically orientated paper, we describe by means of a case example how the couple's conflicts after their separation is unconsciously repeated in the sibling subsystem. It is shown how the intergenerational dynamics can be interrupted by the initiative of the children and the initiated family therapy.

    2016-03-01

    This study examined differences in body-related shame, guilt, pride, and envy based on intrapersonal characteristics of sex, age, and weight status in 527 Canadian adults. Compared to men, women reported significantly higher shame and guilt contextualized to the body. No sex differences were observed for envy or pride. Middle-aged adults reported higher shame and lower pride compared with young adults, whereas no age differences were observed with body-related guilt. Meanwhile, shame and guilt were highest for individuals who had overweight or obese weight status, and pride was highest in individuals with average weight status. Overall, effect sizes were small and there were no significant interaction effects between sex, age, and weight status across body-related emotions. Further research is needed to capture similarities and differences of body-related self-conscious emotions between intrapersonal characteristics, to aid the development of intervention strategies to manage this important dimension of body image.

  3. Evaluation of the ENVI-Met Vegetation Model of Four Common Tree Species in a Subtropical Hot-Humid Area

    Full Text Available Urban trees can significantly improve the outdoor thermal environment, especially in subtropical zones. However, due to the lack of fundamental evaluations of numerical simulation models, design and modification strategies for optimizing the thermal environment in subtropical hot-humid climate zones cannot be proposed accurately. To resolve this issue, this study investigated the physiological parameters (leaf surface temperature and vapor flux and thermal effects (solar radiation, air temperature, and humidity of four common tree species (Michelia alba, Mangifera indica, Ficus microcarpa, and Bauhinia blakeana in both spring and summer in Guangzhou, China. A comprehensive comparison of the observed and modeled data from ENVI-met (v4.2 Science, a three-dimensional microclimate model was performed. The results show that the most fundamental weakness of ENVI-met is the limitation of input solar radiation, which cannot be input hourly in the current version and may impact the thermal environment in simulation. For the tree model, the discrepancy between modeled and observed microclimate parameters was acceptable. However, for the physiological parameters, ENVI-met tended to overestimate the leaf surface temperature and underestimate the vapor flux, especially at midday in summer. The simplified calculation of the tree model may be one of the main reasons. Furthermore, the thermal effect of trees, meaning the differences between nearby treeless sites and shaded areas, were all underestimated in ENVI-met for each microclimate variable. This study shows that the tree model is suitable in subtropical hot-humid climates, but also needs some improvement.

    Full Text Available In primary phase of testing building physical characteristics of the EnviHUT project extensive and semi-intensive roofs with 30° inclination occurred exceptional substrate subsidence. An extensive testing field with retaining geocell-system evinced differential subsidence of individual sectors after six months. Measured subsidence of installed substrate reached 40 % subsidence compared to originally designed height (intended layer thickness. Subsequent deformation of geocell-system additionally caused partial slide of substrate to drip edge area. These slides also influenced initial development of stonecrop plants on its surface. Except functional shortages the aesthetical function of the whole construction is influenced by the mentioned problem. The stated paper solves mentioned issues in view of installation method optimization, selection and modification of used roof substrate and in view of modification of geometric and building installed elements retaining system arrangement. Careful adjustment of roof system geometry and enrichment of original substrate fraction allow full functionality from pitched extensive green roof setting up. The modification scheme and its substantiation is a part of this technical study output.

    2018-01-01

    Urban areas are known to modify meteorological variables producing important differences in small spatial scales (i.e. microscale). These affect human thermal comfort conditions and the dispersion of pollutants, especially those emitted inside the urban area, which finally influence quality of life and the use of public open spaces. In this study, the diurnal evolution of meteorological variables measured in four urban spaces is compared with the results provided by ENVI-met (v 4.0). Measurements were carried out during 3 days with different meteorological conditions in Bilbao in the north of the Iberian Peninsula. The evaluation of the model accuracy (i.e. the degree to which modelled values approach measured values) was carried out with several quantitative difference metrics. The results for air temperature and humidity show a good agreement of measured and modelled values independently of the regional meteorological conditions. However, in the case of mean radiant temperature and wind speed, relevant differences are encountered highlighting the limitation of the model to estimate these meteorological variables precisely during diurnal cycles, in the considered evaluation conditions (sites and weather).

    Indonesia as a tropical country which the character of its climate are hot and humid, the outdoor activity applications are often disrupted due to discomfort in thermal conditions. Massive construction of skyscrapers in urban areas are caused by the increase of human population leads to reduced green and infiltration areas that impact to environmental imbalances and triggering microclimate changes with rising air temperatures on the surface. The area that significantly experiences the rise of temperature in the Central Business District (CBD), which has need an analysis to create thermal comfort conditions to improve the ease of outdoor activities by an approach. This study aims to design the Kemayoran CBD through Climate Sensitive Urban Design especially in hot and humid tropical climate area and analyze thermal comfort level and optimal air conditioning in the outdoor area. This research used a quantitative method by generating the design using Climate Sensitive Urban Design principle through Envi-met 4.1 simulation program to find out the value of PMV, air temperature, wind speed and relative humidity conditions. The design area considers the configuration of buildings such as the distance between buildings, the average height, the orientation of the building, and the width of the road.

    The graphitised carbon solid phase extraction (SPE) sorbent Envi-Carb has been used to fabricate glass fibre filter- Envi-Carb "sandwich" disks for use as a passive sampler for acid herbicides. Passive sampler uptake of a suite of herbicides, including the phenoxyacetic acid herbicides 4-chloro-o-tolyloxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 3,6-dichloro-2-methoxybenzoic acid (Dicamba), was achieved without pH adjustment, demonstrating for the first time a suitable binding phase for passive sampling of acid herbicides at neutral pH. Passive sampling experiments with Duck River (Tasmania, Australia) water spiked at 0.5 μg L(-1) herbicide concentration over a 7 d deployment period showed that sampling rates in Duck River water decreased for seven out of eight herbicides, and in the cases of 3,6-dichloro-2-pyridinecarboxylic acid (Clopyralid) and Dicamba no accumulation of the herbicides occurred in the Envi-Carb over the deployment period. Sampling rates for 4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid (Picloram), 2,4-D and MCPA decreased to approximately 30% of the sampling rates in ultrapure water, whilst sampling rates for 2-(4,6-dimethylpyrimidin-2-ylcarbamoylsulfamoyl) benzoic acid, methyl ester (Sulfometuron-methyl) and 3,5,6-Trichloro-2-pyridinyloxyacetic acid (Triclopyr) were approximately 60% of the ultrapure water sampling rate. For methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alaninate (Metalaxyl-M) there was little variation in sampling rate between passive sampling experiments in ultrapure water and Duck River water. SPE experiments undertaken with Envi-Carb disks using ultrapure water and filtered and unfiltered Duck River water showed that not only is adsorption onto particulate matter in Duck River water responsible for a reduction in herbicide sampling rate, but interactions of herbicides with dissolved or colloidal matter (matter able to pass through a 0.2 μm membrane filter) also reduces the herbicide sampling

    Bandung has a high potential in attracting tourists. This potential impact on building function near tourist attraction that can transform residential uses into commercial uses. Progo Street and its surrounding area used as the case study, which is close to Gedung Sate and Riau Street as tourist destinations in Bandung. Moreover, this transformation is also reinforced by the spatial planning policies in Bandung, known as RTRW and RDTR, said that this area will be fully non-residential area. This condition in some cases could affect thermal comfort. This paper provides the changes of thermal comfort phenomenon that occurs using EnviMet software. The study compares Predicted Mean Voted (PMV) as thermal comfort indicator between existing and Bandung detailed spatial plan (RDTR) condition. The result shows that the PMV value of current condition is higher than future planning, nonetheless the planned area will be changed into higher non-residential buildings and less greeneries. Some environmental factors that are used to calculate PMV such as air temperature, mean radiant temperature, humidity, and wind speed are also examined to find out what makes the plan more comfortable than the existing. Simulations using ENVI-met software could be considered in making more objective planning policy in the future.

    Drawing from social comparison theory, parasocial interaction (PSI) theory, and the literature on envy, a randomized experiment addressed the dynamics of body image, fame, and envy in the context of foodies' foodporn posting on Instagram. Using a 2 (foodie's body type: fat vs. thin) × 2 (foodie's Instagram popularity: unpopular vs. popular) between-subjects design, this experiment (N = 141) examined the effects of an Instagram foodie's body shape and popularity level on peer Instagram users' eating intention, envy, and PSI with the Instagram foodie. The results showed main effects of an Instagram foodie's body shape on peer users' eating intention, and moderating effects of users' self-esteem, body mass index, perfectionism, anorexia, and bulimia nervosa. Additionally, envy mediated the effects of the Instagram foodie's body shape and popularity on peer users' PSI with the foodie and intention to build an Instagram-based friendship. Theoretical contributions to the literature on social comparison and eating disorder and practical implications for fitspiration and social media-based health interventions are discussed.

    ResearchGate, a social network site for academics, prominently displays the achievements of people one follows ("With 150 new reads, X was the most read author from their institute"). The goal of this paper was to examine the emotional and motivational effects of these system-generated messages, thereby extending prior research on envy-evoking status updates on Facebook to a professional context. We also extend the research on social comparisons and more broadly, on emotional responses elicited by social media. Specifically, social media research has largely focused on examining emotional reactions to content that is both generated by and is about others. In this research we directly examine updates generated by the system (ResearchGate) while also directly comparing reactions to updates about others' achievements with reactions to updates that are about the self-i.e., one's personal achievements which are also displayed on ResearchGate ("With 150 new reads, you were the most read author from your institute"). Particular attention was paid to the mediating role of envy and pride. The results of our quasi-experimental field study ( n = 419) showed that the achievements of others elicited envy, whereas personal achievements elicited pride. People exposed to their personal achievements (vs. the achievement of others) showed a higher motivation to work harder. This effect was mediated by pride, but not envy. The theoretical and practical implications of these findings are discussed.

    Full Text Available Urban morphology and increasing building density play a key role in the overall use of energy and promotion of environmental sustainability. The urban environment causes a local increase of temperature, a phenomenon known as Urban Heat Island (UHI. The purpose of this work is the study of the possible formation of an UHI and the evaluation of its magnitude, in the context of a small city, carried out with the ENVI-met® software. For this purpose, a simulation was needed, and this simulation is preparatory for a monitoring campaign on site, which will be held in the immediate future. ENVI-met® simulates the temporal evolution of several thermodynamics parameters on a micro-scale range, creating a 3D, non-hydrostatic model of the interactions between building-atmosphere-vegetation. The weather conditions applied simulate a typical Italian summer heat wave. Three different case-studies have been analyzed: Base Case, Cool Case and Green Case. Analysis of the actual state in the Base Case shows how even in an area with average building density, such as the old town center of a small city, fully developed UHI may rise with strong thermal gradients between built areas and open zones with plenty of vegetation. These gradients arise in a really tiny space (few hundreds of meters, showing that the influence of urban geometry can be decisive in the characterization of local microclimate. Simulations, carried out considering the application of green or cool roofs, showed small relevant effects as they become evident only in large areas heavily built up (metropolis subject to more intense climate conditions.

    2012-02-01

    Full Text Available Abstract Background This paper describes the rationale and design of the ENVIS-ion Study, which aims to determine whether low-dose aspirin reduces the development of white matter hyper-intense (WMH lesions and silent brain infarction (SBI. Additional aims include determining whether a changes in retinal vascular imaging (RVI parameters parallel changes in brain magnetic resonance imaging (MRI; b changes in RVI parameters are observed with aspirin therapy; c baseline cognitive function correlates with MRI and RVI parameters; d changes in cognitive function correlate with changes in brain MRI and RVI and e whether factors such as age, gender or blood pressure influence the above associations. Methods/Design Double-blind, placebo-controlled trial of three years duration set in two Australian academic medical centre outpatient clinics. This study will enrol 600 adults aged 70 years and over with normal cognitive function and without overt cardiovascular disease. Subjects will undergo cognitive testing, brain MRI and RVI at baseline and after 3 years of study treatment. All subjects will be recruited from a 19,000-patient clinical outcome trial conducted in Australia and the United States that will evaluate the effects of aspirin in maintaining disability-free longevity over 5 years. The intervention will be aspirin 100 mg daily versus matching placebo, randomized on a 1:1 basis. Discussion This study will improve understanding of the mechanisms at the level of brain and vascular structure that underlie the effects of aspirin on cognitive function. Given the limited access and high cost of MRI, RVI may prove useful as a tool for the identification of individuals at high risk for the development of cerebrovascular disease and cognitive decline.

    2012-01-01

    This paper explores the interaction between medicine and metaphysics in modern natural philosophy and especially in Descartes' philosophy. I argue that Descartes hypothetical account of birthmarks in connection with his embryology provides an argumentative proof of the metaphysical necessity of a substantial union between mind and body, which however does not threaten his doctrine of the real distinction between these two substances. It would appear that his argument relies on a temporal conception of alethic modalities and provides a new answer to Henricus Regius who in 1641 claimed that, for Descartes, the human being is an ensper accidens.

    2005-01-01

    The Stereotype Content Model hypothesizes anti-Asian American stereotypes differentiating two dimensions: (excessive) competence and (deficient) sociability. The Scale of Anti-Asian American Stereotypes (SAAAS) shows this envious mixed prejudice in six studies. Study 1 began with 131 racial attitude items. Studies 2 and 3 tested 684 respondents on a focused 25-item version. Studies 4 and 5 tested the final 25-item SAAAS on 222 respondents at three campuses; scores predicted outgroup friendships, cultural experiences, and (over)estimated campus presence. Study 6 showed that allegedly low sociability, rather than excessively high competence, drives rejection of Asian Americans, consistent with system justification theory. The SAAAS demonstrates mixed, envious anti-Asian American prejudice, contrasting with more-often-studied contemptuous racial prejudices (i.e., against Blacks).

    This paper describes an integrated model developed by the Korean Atomic Energy Research Institute (KAERI) to simulate options for managing spent nuclear fuel (SNF) in South Korea. A companion paper (Hwang and Miller, 2009) describes a performance assessment model to address the long-term safety of alternative geological disposal options for different waste streams. The model addresses alternative concepts for storage, transportation, and processing of SNF of different types (Candu, PWR), leading up to permanent disposal in geological repositories. It uses the GoldSim software to simulate the logistics of the associated activities, including the associated capital and operating costs. The model's results allow direct comparison of alternative waste management concepts, and predict the sizes and timings of different facilities required. Future versions of the model will also address the uncertainties associated with the different system components in order to provide risk-based assessments. (authors)

    2014-01-01

    Non-trivial software systems integrate many artifacts expressed in multiple modeling and program- ming languages. However, even though these artifacts heavily depend on each other, existing development envi- ronments do not sufficiently support handling relations between artifacts in different...... languages. By means of a literature survey, tool prototyping and experiments we study the design space of multi-language development environments (MLDEs)—tools that consider the cross-language relations as first artifacts.

To what extent MLDEs are desired by users, and for what support features? Our main conclusions are that (a) cross-language re- lations are ubiquitous and troublesome in multi-language systems, (b) users highly appreciated cross-language sup- port mechanisms of MLDEs and (c...

  8. Emotion, power and identity. Emotional display of envy when taking on management roles in a professional hierarchy.

    Science.gov (United States)

    Sebrant, Ulla

    2014-01-01

    Drawing on a previous study of organising processes and the construction of identity in a Swedish geriatric clinic, the impact of emotions is brought to the fore in the interpretation of power relations among professional groups. The purpose of this paper is to find a way to interpret emotions as discursively constructed in organising processes. A sequence of critical events is described where leading positions were negotiated at the clinic. Senior physicians and head nurses are highlighted as opposing forces in a struggle where envious emotions seemed to be a driving force in the political interplay. The empirical material in this paper comes from the previous study. It is a set of participant observations and parts of interviews that took place before and after the implementation of a new organisational plan for the clinic. The envious and regressive undertone in the relationships between the actors made them act for egocentric reasons instead of creating new ways of collaborating and learning new leading roles. The power relations of the medical hierarchy were reproduced, which made new ways of relating threatening and difficult to achieve. The results of the study confirm that people involved and perhaps in conflict with each other have to be able to, or get help to, make sense of their emotional experiences to employ them constructively. Otherwise they fall back into well-known patterns in order to feel secure. A vital part of learning in change processes is the support to individuals and groups in gaining emotional understanding of themselves and others. Leaders and managers who often are initiators of change ought to be aware of the importance of emotional support in change processes. If they are not, they are destined to be a part of the confusion and unable to lead or support their staff in change processes.

    Full Text Available El objetivo es evaluar el estado nutricional, la composición y proporción corporal con relación a las condiciones socio-ambientales de residencia de la población infanto-juvenil de las localidades de Verónica, Pipinas y La Viruta (partido de Punta Indio, provincia de Buenos Aires. Se realizó un estudio antropométrico transversal en 845 niños (47.5% varones y 52.5% mujeres de 3 a 15 años. Se relevaron peso, talla, estatura sentado, perímetro braquial y pliegues tricipital y subescapular, y se calcularon indicadores nutricionales, de proporción y composición corporal, utilizando la referencia Third National Health and Nutrition Examination Survey. La información socio-ambiental se obtuvo aplicando encuestas estructuradas y fue procesada mediante Análisis de Componentes Principales Categórico. Esto permitió diferenciar cuatro grupos: I “urbano favorecido”; II “urbano intermedio”; III “urbano desfavorable” y IV “rural”. Para cada grupo se calcularon prevalencias de estado nutricional que fueron comparadas mediante la prueba exacta de Fisher. Los resultados indicaron 3.8% de desnutrición, 13.1% de sobrepeso y 10.9% de obesidad. La malnutrición por déficit y por exceso se vio acompañada por modificaciones en la composición corporal. El grupo “rural” se diferenció de los otros grupos por no presentar casos de desnutrición crónica. Estos resultados permiten concluir que la población estudiada experimenta una transición nutricional avanzada, dada por bajas prevalencias de desnutrición y altas prevalencias de sobrepeso y obesidad. Esta situación puede interpretarse en el marco de las transformaciones económicas intensas ocurridas recientemente en el partido de Punta Indio, las cuales no han conducido a erradicar la malnutrición, sino a cambiar su polaridad hacia el exceso de peso. PALABRAS CLAVE malnutrición; proporción y composición corporal; variables socio-ambientales; antropología biológica The aim of this work was to evaluate nutritional status, body composition, and proportion in relation to socio-environmental conditions of residence in the infant-juvenile population of three towns in the district of Punta Indio, in Buenos Aires. A cross-sectional study was performed in 845 children (47.5% male and 52.5% female 3 to 15 years old. Weight, height, sitting height, arm circumference, and triceps and subscapular skinfolds were surveyed, and nutritional indicators, body composition, and proportion were calculated using the Third National Health and Nutrition Examination Survey reference. Socio-environmental information was obtained through structured questionnaires and was processed with a Categorical Principal Components Analysis which allowed to distinguish four groups: I "favored urban"; II "intermediate urban"; III "urban unfavorable", and IV "rural". In each group, prevalence of nutritional status was also calculated and compared using Fisher's exact test. The results for the total population indicated 3.8% of undernutrition, 13.1% of overweight, and 10.9% of obesity. All types of malnutrition were accompanied by changes in body composition. Group IV was different from the other groups in that it did not present cases of chronic undernutrition. These results allow us to conclude that the studied population has experienced an advanced nutrition transition, characterized by low prevalence of undernutrition and high prevalence of overweight and obesity. This situation can be related to profound economic changes that have recently occurred in the district of Punta Indio, which have not led to the elimination of malnutrition but to changing its polarity towards excess weight.

  8. Responder Feelings in a Three-Player Three-Option Ultimatum Game: Affective Determinants of Rejection Behavior

    Directory of Open Access Journals (Sweden)

    Hans-Rüdiger Pfister

    2012-02-01

    Full Text Available This paper addresses the role of affect and emotions in shaping the behavior of responders in the ultimatum game. A huge amount of research shows that players do not behave in an economically rational way in the ultimatum game, and emotional mechanisms have been proposed as a possible explanation. In particular, feelings of fairness, anger and envy are likely candidates as affective determinants. We introduce a three-player ultimatum game with three-options, which permits the responder to either penalize the proposer or to penalize a third party by rejecting offers. This allows for partially distinguishing rejections due to a retaliation motive driven by anger towards the proposer from rejections due to inequity aversion driven by feelings of envy towards a third party. Results from two experiments suggest that responders experience feelings of dissatisfaction and unfairness if their share is small in comparison to the proposer���s share; anger, then, may trigger rejections towards the proposer. Responders also experience dissatisfaction and envy when third party shares exceed their own shares; however, in contrast to anger, envy does not trigger rejections and is dissociated from the decision to accept or reject an offer. We conclude that acting upon anger is socially acceptable, whereas envy is not acceptable as a reason for action. Furthermore, we find that responders generally feel better after rejections, suggesting that rejections serve to regulate one’s affective state.

    LYMAN, EMILY L.; LUTHAR, SUNIYA S.

    2015-01-01

    This study involved two academically-gifted samples of 11th and 12th grade youth at the socioeconomic status (SES) extremes; one from an exclusive private, affluent school, and the other from a magnet school with low-income students. Negative and positive adjustment outcomes were examined in relation to multiple dimensions of perfectionism including perceived parental pressures to be perfect, personal perfectionistic self-presentation, and envy of peers. The low-income students showed some areas of relative vulnerability, but when large group differences were found, it was the affluent youth who were at a disadvantage, with substantially higher substance use and peer envy. Affluent girls seemed particularly vulnerable, with pronounced elevations in perfectionistic tendencies, peer envy, as well as body dissatisfaction. Examination of risk and protective processes showed that relationships with mothers were associated with students’ distress as well as positive adjustment. Additionally, findings showed links between (a) envy of peers and multiple outcomes (among high SES girls in particular), (b) dimensions of perfectionism in relation to internalizing symptoms, and (c) high extrinsic versus intrinsic values in relation to externalizing symptoms.

  19. Operational SAR Data Processing in GIS Environments for Rapid Disaster Mapping

    Science.gov (United States)

    Bahr, Thomas

    2014-05-01

    The use of SAR data has become increasingly popular in recent years and in a wide array of industries. Having access to SAR can be highly important and critical especially for public safety. Updating a GIS with contemporary information from SAR data allows to deliver a reliable set of geospatial information to advance civilian operations, e.g. search and rescue missions. SAR imaging offers the great advantage, over its optical counterparts, of not being affected by darkness, meteorological conditions such as clouds, fog, etc., or smoke and dust, frequently associated with disaster zones. In this paper we present the operational processing of SAR data within a GIS environment for rapid disaster mapping. For this technique we integrated the SARscape modules for ENVI with ArcGIS®, eliminating the need to switch between software packages. Thereby the premier algorithms for SAR image analysis can be directly accessed from ArcGIS desktop and server environments. They allow processing and analyzing SAR data in almost real time and with minimum user interaction. This is exemplified by the November 2010 flash flood in the Veneto region, Italy. The Bacchiglione River burst its banks on Nov. 2nd after two days of heavy rainfall throughout the northern Italian region. The community of Bovolenta, 22 km SSE of Padova, was covered by several meters of water. People were requested to stay in their homes; several roads, highways sections and railroads had to be closed. The extent of this flooding is documented by a series of Cosmo-SkyMed acquisitions with a GSD of 2.5 m (StripMap mode). Cosmo-SkyMed is a constellation of four Earth observation satellites, allowing a very frequent coverage, which enables monitoring using a very high temporal resolution. This data is processed in ArcGIS using a single-sensor, multi-mode, multi-temporal approach consisting of 3 steps: (1) The single images are filtered with a Gamma DE-MAP filter. (2) The filtered images are geocoded using a reference

  20. Scalar multi-wormholes

    International Nuclear Information System (INIS)

    Egorov, A I; Kashargin, P E; Sushkov, Sergey V

    2016-01-01

    In 1921 Bach and Weyl derived the method of superposition to construct new axially symmetric vacuum solutions of general relativity. In this paper we extend the Bach–Weyl approach to non-vacuum configurations with massless scalar fields. Considering a phantom scalar field with the negative kinetic energy, we construct a multi-wormhole solution describing an axially symmetric superposition of N wormholes. The solution found is static, everywhere regular and has no event horizons. These features drastically tell the multi-wormhole configuration from other axially symmetric vacuum solutions which inevitably contain gravitationally inert singular structures, such as ‘struts’ and ‘membranes’, that keep the two bodies apart making a stable configuration. However, the multi-wormholes are static without any singular struts. Instead, the stationarity of the multi-wormhole configuration is provided by the phantom scalar field with the negative kinetic energy. Anther unusual property is that the multi-wormhole spacetime has a complicated topological structure. Namely, in the spacetime there exist 2 N asymptotically flat regions connected by throats.

    2013-01-01

    Cake cutting is a fundamental model in fair division; it represents the problem of fairly allocating a heterogeneous divisible good among agents with different preferences. The central criteria of fairness are proportionality and envy-freeness, and many of the existing protocols are designed...... to guarantee proportional or envy-free allocations, when the participating agents follow the protocol. However, typically, all agents following the protocol is not guaranteed to result in a Nash equilibrium. In this paper, we initiate the study of equilibria of classical cake cutting protocols. We consider one...... of the simplest and most elegant continuous algorithms -- the Dubins-Spanier procedure, which guarantees a proportional allocation of the cake -- and study its equilibria when the agents use simple threshold strategies. We show that given a cake cutting instance with strictly positive value density functions...

Also, high emitting vehicles need to be considered in the modeling of mobile-source emissions, because they contribute to a large portion of the total emissions, although they comprise a small portion of the vehicle fleet. In the context of this research, the thesis quantifies the envi...

    2004-01-01

    The scholarly literature in management has paid little attention to the study of Biblical figures as leaders. This paper aims to advance the effort to fill this gap by demonstrating that many insights about successful and unsuccessful leadership may be derived from the Bible. Successful leaders demonstrated a willingness to be different, a passion for justice, humility, and a concern for others. Unsuccessful leaders were sidetracked from their mission by the hunger for power or by lust and envy.

Our thesis is that mathematics joint with a suitable software, such as Mathematica, are a source of ideas for creating forms in architecture. In this sense we have designed new architectural volumes using mathematics as a main tool. The results support our thesis, since the volumes created with Mathematica have nothing to envy to others created with specific software for designing.

  8. Biomagnetic monitoring as a validation tool for local air quality models: a case study for an urban street canyon.

    Science.gov (United States)

    Hofman, Jelle; Samson, Roeland

    2014-09-01

    Biomagnetic monitoring of tree leaf deposited particles has proven to be a good indicator of the ambient particulate concentration. The objective of this study is to apply this method to validate a local-scale air quality model (ENVI-met), using 96 tree crown sampling locations in a typical urban street canyon. To the best of our knowledge, the application of biomagnetic monitoring for the validation of pollutant dispersion modeling is hereby presented for the first time. Quantitative ENVI-met validation showed significant correlations between modeled and measured results throughout the entire in-leaf period. ENVI-met performed much better at the first half of the street canyon close to the ring road (r=0.58-0.79, RMSE=44-49%), compared to second part (r=0.58-0.64, RMSE=74-102%). The spatial model behavior was evaluated by testing effects of height, azimuthal position, tree position and distance from the main pollution source on the obtained model results and magnetic measurements. Our results demonstrate that biomagnetic monitoring seems to be a valuable method to evaluate the performance of air quality models. Due to the high spatial and temporal resolution of this technique, biomagnetic monitoring can be applied anywhere in the city (where urban green is present) to evaluate model performance at different spatial scales.

  9. An exploration of jealousy in nursing: a Kleinian analysis.

    Science.gov (United States)

    Evans, Alicia M; Traynor, Michael; Glass, Nel

    2014-06-01

    It is well established that nursing practice produces considerable anxiety, and it can also give rise to envy and jealousy. While envy in nursing was identified in the literature more than 50 years ago, there remains a paucity of articles addressing either envy or jealousy for nurses. In a recent research study on current experiences of clinical practice, we analysed a fragment of nurses' speech via Klein's theory of jealousy. The results revealed that the nurses expressed jealousy at the privilege afforded to doctors. We argue that it is important to acknowledge jealousy in nursing practice because it has the potential for 'spoiling' effective care delivery and as such, can have detrimental ramifications in the health system. Also, jealousy may keep the nurse from fully focusing on their nursing practice in that it divides the nurse's attention and so limits the nurse's treatment of the patient. Nurses' jealousy of doctors is a taboo topic in nursing, and yet it warrants serious consideration due to the potential deleterious consequences that can arise when this dynamic is present. © 2013 John Wiley & Sons Ltd.

    Detection and deterrence of spoofing of user authentication may be achieved by including a cryptographic fingerprint unit within a hardware device for authenticating a user of the hardware device. The cryptographic fingerprint unit includes an internal physically unclonable function ("PUF") circuit disposed in or on the hardware device, which generates a PUF value. Combining logic is coupled to receive the PUF value, combines the PUF value with one or more other authentication factors to generate a multi-factor authentication value. A key generator is coupled to generate a private key and a public key based on the multi-factor authentication value while a decryptor is coupled to receive an authentication challenge posed to the hardware device and encrypted with the public key and coupled to output a response to the authentication challenge decrypted with the private key.

    Preliminary analysis of pion production in 1.2 GeV/nucleon Kr-RbBr collisions is presented. The negative pion multiplicity is consistent with a convolution of Poisson distributions and a freeze-out density between 1/3 and 1/2 normal nuclear density is extracted. Global negative pion kinematic variables are used to search for possible structure in the multi-pion emission. No evidence for structured emission or conservation constraints is found. Pion interferometry analysis gives a source radius of 5.4 +- 1.2 Fermi and a freeze-out density of .3 +- .2 times normal nuclear density. 10 refs., 5 figs

    Slobodník, J; Oztezkizan, O; Lingeman, H; Brinkman, U A

    1996-10-25

    The suitability of Empore-activated carbon disks (EACD), Envi-Carb graphitized carbon black (GCB) and CPP-50 graphitized carbon for the trace enrichment of polar pesticides from water samples was studied by means of off-line and on-line solid-phase extraction (SPE). In the off-line procedure, 0.5-2 l samples spiked with a test mixture of oxamyl, methomyl and aldicarb sulfoxide were enriched on EnviCarb SPE cartridges or 47 mm diameter EACD and eluted with dichloromethane-methanol. After evaporation, a sample was injected onto a C18-bonded silica column and analysed by liquid chromatography with ultraviolet (LC-UV) detection. EACD performed better than EnviCarb cartridges in terms of breakthrough volumes (> 2 l for all test analytes), reproducibility (R.S.D. of recoveries, 4-8%, n = 3) and sampling speed (100 ml/min); detection limits in drinking water were 0.05-0.16 microgram/l. In the on-line experiments, 4.6 mm diameter pieces cut from original EACD and stacked onto each other in a 9 mm long precolumn, and EnviCarb and CPP-50 packed in 10 x 2.0 mm I.D. precolumn, were tested, and 50-200 ml spiked water samples were preconcentrated. Because of the peak broadening caused by the strong sorption of the analytes on carbon, the carbon-packed precolumns were eluted by a separate stream of 0.1 ml/min acetonitrile which was mixed with the gradient LC eluent in front of the C18 analytical column. The final on-line procedure was also applied for the less polar propoxur, carbaryl and methiocarb. EnviCarb could not be used due to its poor pressure resistance. CPP-50 provided less peak broadening than EACD: peak widths were 0.1-0.3 min and R.S.D. of peak heights 4-14% (n = 3). In terms of analyte trapping efficiency on-line SPE-LC-UV with a CPP-50 precolumn also showed better performance than when Bondesil C18/OH or polymeric PLRP-S was used, but chromatographic resolution was similar. With the CPP-50-based system, detection limits of the test compounds were 0.05-1 microgram

    2017-01-01

    Full Text Available Decision support methods have an important role regarding the envi­ronmental and landscape planning problems. In this research, one of the decision support methods - multiplicative version of Promethee - has been applied for assessment of five main parks in Novi Sad. The procedure required defining a set of criteria that were as follows: aesthetic, ecological and social values of analyzed parks. For each criterion an appropriate Promethee preference function was adopted with corresponding threshold values. The final result of the process was the ranking of parks by their aesthetic, ecological and social quality and importance for the City of Novi Sad. The result can help urban planners and responsible city bodies in their future actions aimed at improving development and management of analyzed parks. Two main directions of a future research were identified: (a testing appli­cability of other decision support methods, along with Promethee, on the same problem and comparison of their results; and (b analysis of the criteria set more closely by expanding it and/or including a set of indicators.

    2001-01-01

    For more than 30 years, the author has studied the model-theoretic aspects of the theory of valued fields and multi-valued fields. Many of the key results included in this book were obtained by the author whilst preparing the manuscript. Thus the unique overview of the theory, as developed in the book, has been previously unavailable. The book deals with the theory of valued fields and mutli-valued fields. The theory of Prüfer rings is discussed from the `geometric' point of view. The author shows that by introducing the Zariski topology on families of valuation rings, it is possible to distinguish two important subfamilies of Prüfer rings that correspond to Boolean and near Boolean families of valuation rings. Also, algebraic and model-theoretic properties of multi-valued fields with near Boolean families of valuation rings satisfying the local-global principle are studied. It is important that this principle is elementary, i.e., it can be expressed in the language of predicate calculus. The most important...

    Full Text Available In this paper a multi-period multi-product multi-objective aggregate production planning (APP model is proposed for an uncertain multi-echelon supply chain considering financial risk, customer satisfaction, and human resource training. Three conflictive objective functions and several sets of real constraints are considered concurrently in the proposed APP model. Some parameters of the proposed model are assumed to be uncertain and handled through a two-stage stochastic programming (TSSP approach. The proposed TSSP is solved using three multi-objective solution procedures, i.e., the goal attainment technique, the modified ε-constraint method, and STEM method. The whole procedure is applied in an automotive resin and oil supply chain as a real case study wherein the efficacy and applicability of the proposed approaches are illustrated in comparison with existing experimental production planning method.

    Various types of multi-stage decoding for multi-level modulation codes are investigated. It is shown that if the component codes of a multi-level modulation code and types of decoding at various stages are chosen properly, high spectral efficiency and large coding gain can be achieved with reduced decoding complexity. Particularly, it is shown that the difference in performance between the suboptimum multi-stage soft-decision maximum likelihood decoding of a modulation code and the single-stage optimum soft-decision decoding of the code is very small, only a fraction of dB loss in signal to noise ratio at a bit error rate (BER) of 10(exp -6).

The patient, a 46-year-old female, presented with lower back pain radiating into the left lower extremity. Radiographs and CT scans of the lumbar spine revealed bilateral pars defects at L3-L5. The patient underwent lumbar discectomy and interbody fusion of L4-S1 as well as direct repair of the pars defect at L3. There were no postoperative complications, and by seven months the patient had improved clinically. While previous reports describe the use of either direct repair or fusion in the treatment of spondylolysis, we are unaware of reports describing the use of both techniques at adjacent levels.

  10. Multi-robot caravanning

    We study multi-robot caravanning, which is loosely defined as the problem of a heterogeneous team of robots visiting specific areas of an environment (waypoints) as a group. After formally defining this problem, we propose a novel solution that requires minimal communication and scales with the number of waypoints and robots. Our approach restricts explicit communication and coordination to occur only when robots reach waypoints, and relies on implicit coordination when moving between a given pair of waypoints. At the heart of our algorithm is the use of leader election to efficiently exploit the unique environmental knowledge available to each robot in order to plan paths for the group, which makes it general enough to work with robots that have heterogeneous representations of the environment. We implement our approach both in simulation and on a physical platform, and characterize the performance of the approach under various scenarios. We demonstrate that our approach can successfully be used to combine the planning capabilities of different agents. © 2013 IEEE.

    A multi-gas sensor is provided which modulates a polarized light beam over a broadband of wavelengths between two alternating orthogonal polarization components. The two orthogonal polarization components of the polarization modulated beam are directed along two distinct optical paths. At least one optical path contains one or more spectral discrimination element, with each spectral discrimination element having spectral absorption features of one or more gases of interest being measured. The two optical paths then intersect, and one orthogonal component of the intersected components is transmitted and the other orthogonal component is reflected. The combined polarization modulated beam is partitioned into one or more smaller spectral regions of interest where one or more gases of interest has an absorption band. The difference in intensity between the two orthogonal polarization components is then determined in each partitioned spectral region of interest as an indication of the spectral emission/absorption of the light beam by the gases of interest in the measurement path. The spectral emission/absorption is indicative of the concentration of the one or more gases of interest in the measurement path. More specifically, one embodiment of the present invention is a gas filter correlation radiometer which comprises a polarizer, a polarization modulator, a polarization beam splitter, a beam combiner, wavelength partitioning element, and detection element. The gases of interest are measured simultaneously and, further, can be measured independently or non-independently. Furthermore, optical or electronic element are provided to balance optical intensities between the two optical paths.

  14. Multi-purpose reactor

    International Nuclear Information System (INIS)

    1991-05-01

    The Multi-Purpose-Reactor (MPR), is a pool-type reactor with an open water surface and variable core arrangement. Its main feature is plant safety and reliability. Its power is 22MW t h, cooled by light water and moderated by beryllium. It has platetype fuel elements (MTR type, approx. 20%. enriched uranium) clad in aluminium. Its cobalt (Co 60 ) production capacity is 50000 Ci/yr, 200 Ci/gr. The distribution of the reactor core and associated control and safety systems is essentially based on the following design criteria: - upwards cooling flow, to waive the need for cooling flow inversion in case the reactor is cooled by natural convection if confronted with a loss of pumping power, and in order to establish a superior heat transfer potential (a higher coolant saturation temperature); - easy access to the reactor core from top of pool level with the reactor operating at full power, in order to facilitate actual implementation of experiments. Consequently, mechanisms associated to control and safety rods s,re located underneath the reactor tank; - free access of reactor personnel to top of pool level with the reactor operating at full power. This aids in the training of personnel and the actual carrying out of experiments, hence: - a vast water column was placed over the core to act as radiation shielding; - the core's external area is cooled by a downwards flow which leads to a decay tank beyond the pool (for N 16 to decay); - a small downwards flow was directed to stream downwards from above the reactor core in order to drag along any possibly active element; and - a stagnant hot layer system was placed at top of pool level so as to minimize the upwards coolant flow rising towards pool level

  15. Multi-view Multi-sparsity Kernel Reconstruction for Multi-class Image Classification

    KAUST Repository

    Zhu, Xiaofeng

    2015-05-28

    This paper addresses the problem of multi-class image classification by proposing a novel multi-view multi-sparsity kernel reconstruction (MMKR for short) model. Given images (including test images and training images) representing with multiple visual features, the MMKR first maps them into a high-dimensional space, e.g., a reproducing kernel Hilbert space (RKHS), where test images are then linearly reconstructed by some representative training images, rather than all of them. Furthermore a classification rule is proposed to classify test images. Experimental results on real datasets show the effectiveness of the proposed MMKR while comparing to state-of-the-art algorithms.

Multi-color dithering is a generalization of standard bi-level dithering. Combined with tetrahedral color separation, multi-color dithering makes it possible to print images made of a set of non-standard inks. In contrast to most previous color halftoning methods, multi-color dithering ensures by construction that the different selec...

    Multi-destination maps are a kind of navigation maps aimed to guide visitors to multiple destinations within a region, which can be of great help to urban visitors. However, they have not been developed in the current online map service. To address this issue, we introduce a novel layout model designed especially for generating multi-destination maps, which considers the global and local layout of a multi-destination map. We model the layout problem as a graph drawing that satisfies a set of hard and soft constraints. In the global layout phase, we balance the scale factor between ROIs. In the local layout phase, we make all edges have good visibility and optimize the map layout to preserve the relative length and angle of roads. We also propose a perturbation-based optimization method to find an optimal layout in the complex solution space. The multi-destination maps generated by our system are potential feasible on the modern mobile devices and our result can show an overview and a detail view of the whole map at the same time. In addition, we perform a user study to evaluate the effectiveness of our method, and the results prove that the multi-destination maps achieve our goals well.

  1. Modified Multi Prime RSA Cryptosystem

    RSA [1] is one of the mostly used cryptosystem in securing data and information. Though, it has been recently discovered that RSA has some weaknesses and in advance technology, RSA is believed to be inefficient especially when it comes to decryption. Thus, a new algorithm called Multi prime RSA, an extended version of the standard RSA is studied. Then, a modification is made to the Multi prime RSA where another keys is shared secretly between the receiver and the sender to increase the securerity. As in RSA, the methodology used for modified Multi-prime RSA also consists of three phases; 1. Key Generation in which the secret and public keys are generated and published. In this phase, the secrecy is improved by adding more prime numbers and addition of secret keys. 2. Encryption of the message using the public and secret keys given. 3. Decryption of the secret message using the secret key generated. For the decryption phase, a method called Chinese Remainder Theorem is used which helps to fasten the computation. Since Multi prime RSA use more than two prime numbers, the algorithm is more efficient and secure when compared to the standard RSA. Furthermore, in modified Multi prime RSA another secret key is introduced to increase the obstacle to the attacker. Therefore, it is strongly believed that this new algorithm is better and can be an alternative to the RSA.

    The present study examined the relationship between personality and individual differences in multi-tasking ability. Participants enrolled at the University of Utah completed measures of multi-tasking activity, perceived multi-tasking ability, impulsivity, and sensation seeking. In addition, they performed the Operation Span in order to assess their executive control and actual multi-tasking ability. The findings indicate that the persons who are most capable of multi-tasking effectively are not the persons who are most likely to engage in multiple tasks simultaneously. To the contrary, multi-tasking activity as measured by the Media Multitasking Inventory and self-reported cell phone usage while driving were negatively correlated with actual multi-tasking ability. Multi-tasking was positively correlated with participants' perceived ability to multi-task ability which was found to be significantly inflated. Participants with a strong approach orientation and a weak avoidance orientation--high levels of impulsivity and sensation seeking--reported greater multi-tasking behavior. Finally, the findings suggest that people often engage in multi-tasking because they are less able to block out distractions and focus on a singular task. Participants with less executive control--low scorers on the Operation Span task and persons high in impulsivity--tended to report higher levels of multi-tasking activity.

  2. Damage Assessment for Disaster Relief Efforts in Urban Areas Using Optical Imagery and LiDAR Data

    Bahr, Thomas

    2014-05-01

    Imagery combined with LiDAR data and LiDAR-derived products provides a significant source of geospatial data which is of use in disaster mitigation planning. Feature rich building inventories can be constructed from tools with 3D rooftop extraction capabilities, and two dimensional outputs such as DSMs and DTMs can be used to generate layers to support routing efforts in Spatial Analyst and Network Analyst workflows. This allows us to leverage imagery and LiDAR tools for disaster mitigation or other scenarios. Software such as ENVI, ENVI LiDAR, and ArcGIS® Spatial and Network Analyst can therefore be used in conjunction to help emergency responders route ground teams in support of disaster relief efforts. This is exemplified by a case study against the background of the magnitude 7.0 earthquake that struck Haiti's capital city of Port-au-Prince on January 12, 2010. Soon after, both LiDAR data and an 8-band WorldView-2 scene were collected to map the disaster zone. The WorldView-2 scene was orthorectified and atmospherically corrected in ENVI prior to use. ENVI LiDAR was used to extract the DSM, DTM, buildings, and debris from the LiDAR data point cloud. These datasets provide a foundation for the 2D portion of the analysis. As the data was acquired over an area of dense urbanization, the majority of ground surfaces are roads, and standing buildings and debris are actually largely separable on the basis of elevation classes. To extract the road network of Port-au-Prince, the LiDAR-based feature height information was fused with the WorldView-2 scene, using ENVI's object-based feature extraction approach. This road network was converted to a network dataset for further analysis by the ArcGIS Network Analyst. For the specific case of Haiti, the distribution of blue tarps, used as accommodations for refugees, provided a spectrally distinct target. Pure blue tarp pixel spectra were selected from the WorldView-2 scene and input as a reference into ENVI's Spectral Angle

    While classically cryptography is concerned with the problem of private communication among two entities, say players, in modern cryptography multi-player protocols play an important role. And among these, it is probably fair to say that secret sharing, and its stronger version verifiable secret...... sharing (VSS), as well as multi-party computation (MPC) belong to the most appealing and/or useful ones. The former two are basic tools to achieve better robustness of cryptographic schemes against malfunction or misuse by “decentralizing” the security from one single to a whole group of individuals...... (captured by the term threshold cryptography). The latter allows—at least in principle—to execute any collaboration among a group of players in a secure way that guarantees the correctness of the outcome but simultaneously respects the privacy of the participants. In this work, we study three aspects...

    Ensemble Clustering has been developed to provide an alternative way of obtaining more stable and accurate clustering results. It aims to avoid the biases of individual clustering algorithms. However, it is still a challenge to develop an efficient and robust method for Ensemble Clustering. Based on an existing ensemble clustering method, Consensus Clustering (CC), this paper introduces an advanced Consensus Clustering algorithm called Multi-Optimisation Consensus Clustering (MOCC), which utilises an optimised Agreement Separation criterion and a Multi-Optimisation framework to improve the performance of CC. Fifteen different data sets are used for evaluating the performance of MOCC. The results reveal that MOCC can generate more accurate clustering results than the original CC algorithm.

    Lonza, M

    2008-01-01

    Coupled-bunch instabilities excited by the interaction of the particle beam with its surroundings can seriously limit the performance of circular particle accelerators. These instabilities can be cured by the use of active feedback systems based on sensors capable of detecting the unwanted beam motion and actuators that apply the feedback correction to the beam. The advances in electronic technology now allow the implementation of feedback loops using programmable digital systems. Besides important advantages in terms of flexibility and reproducibility, digital systems open the way to the use of novel diagnostic tools and additional features. The lecture will first introduce coupled-bunch instabilities analysing the equation of motion of charged particles and the different modes of oscillation of a multi-bunch beam, showing how they can be observed and measured. Different types of feedbacks systems will then be presented as examples of real implementations that belong to the history of multi-bunch feedback sy...

    Fazekas, P.; Kee Haeyoung.

    1993-06-01

    A multi-channel generalization of Doniach's Kondo necklace model is formulated, and its phase diagram studied in the mean-field approximation. Our intention is to introduce the possible simplest model which displays some of the features expected from the overscreened Kondo lattice. The N conduction electron channels are represented by N sets of pseudospins τ J , j = 1 1,..., N which are all antiferromagnetically coupled to a periodic array of modul S = 1/2 spins. Exploiting permutation symmetry in the channel index j allows us to write down the self-consistency equation for general N. For N > 2, we find that the critical temperature is rising with increasing Kondo interaction; we interpret this effect by pointing out that the Kondo coupling creates the composite pseudospin objects which undergo an ordering transition. The relevance of our findings to the underlying fermionic multi-channel problem is discussed. (author). 33 refs, 1 fig

    2014-12-19

    Coupled-bunch instabilities excited by the interaction of the particle beam with its surroundings can seriously limit the performance of circular particle accelerators. These instabilities can be cured by the use of active feedback systems based on sensors capable of detecting the unwanted beam motion and actuators that apply the feedback correction to the beam. Advances in electronic technology now allow the implementation of feedback loops using programmable digital systems. Besides important advantages in terms of flexibility and reproducibility, digital systems open the way to the use of novel diagnostic tools and additional features. We first introduce coupled-bunch instabilities, analysing the equation of motion of charged particles and the different modes of oscillation of a multi-bunch beam, showing how they can be observed and measured. Different types of feedback systems will then be presented as examples of real implementations that belong to the history of multi-bunch feedback systems. The main co...

    A readily accessible framework that allows for evaluating impacts and comparing tradeoffs among factors in energy policy, expansion planning, and investment decision making is lacking. Recognizing this, the Joint Institute for Strategic Energy Analysis (JISEA) funded an exploration of multi-metric sustainability analysis (MMSA) to provide energy decision makers with a means to make more comprehensive comparisons of energy technologies. The resulting MMSA tool lets decision makers simultaneously compare technologies and potential deployment locations.

    Spectroscopic ellipsometry is an established technique, particularly useful for thickness measurements of thin films. It measures polarization rotation after a single reflection of a beam of light on the measured substrate at a given incidence angle. In this paper, we report the development of multi-pass spectroscopic ellipsometry where the light beam reflects multiple times on the sample. We have investigated both theoretically and experimentally the effect of sample reflectivity, number of reflections (passes), angles of incidence and detector dynamic range on ellipsometric observables tanΨ and cosΔ. The multiple pass approach provides increased sensitivity to small changes in Ψ and Δ, opening the way for single measurement determination of optical thickness T, refractive index n and absorption coefficient k of thin films, a significant improvement over the existing techniques. Based on our results, we discuss the strengths, the weaknesses and possible applications of this technique. - Highlights: • We present multi-pass spectroscopic ellipsometry (MPSE), a multi-pass approach to ellipsometry. • Different detectors, samples, angles of incidence and number of passes were tested. • N passes improve polarization ratio sensitivity to the power of N. • N reflections improve phase shift sensitivity by a factor of N. • MPSE can significantly improve thickness measurements in thin films

    Full Text Available Multi-dimensional Fuzzy differential equations driven by multi-dimen-sional Liu process, have been intensively applied in many fields. However, we can not obtain the analytic solution of every multi-dimensional fuzzy differential equation. Then, it is necessary for us to discuss the numerical results in most situations. This paper focuses on the numerical method of multi-dimensional fuzzy differential equations. The multi-dimensional fuzzy Taylor expansion is given, based on this expansion, a numerical method which is designed for giving the solution of multi-dimensional fuzzy differential equation via multi-dimensional Euler method will be presented, and its local convergence also will be discussed.

  17. Life history, code of honor, and emotional responses to inequality in an economic game.

    Pedersen, Eric J; Forster, Daniel E; McCullough, Michael E

    2014-10-01

    The code of honor, which is characterized by a preoccupation with reputation and willingness to take retaliatory action, has been used extensively to explain individual and cultural differences in peoples' tendencies to behave aggressively. However, research on the relationship between the code of honor and emotional responses to social interactions has been limited in scope, focusing primarily on anger in response to insults and reputational threats. Here we broaden this scope by examining the relationship between code of honor and emotional reactions in response to an unfair economic exchange that resulted in unequal monetary earnings among 3 laboratory participants. We found that endorsement of the code of honor was related to anger and envy in response to unfair monetary distributions. Interestingly, code of honor predicted envy above and beyond what could be accounted for by anger, but the converse was not the case. This suggests that the code of honor influenced perceptions of how subjects viewed their own earnings relative to those of others, which consequently was responsible for their apparent anger as a result of the economic transaction. Furthermore, the unique relationship between code of honor and envy was present only for subjects who received unfair treatment and not for subjects who merely witnessed unfair treatment. Additionally, we replicated previous findings that harsh childhood environmental conditions are associated with endorsement of the code of honor, highlighting the potential value of incorporating a life history theoretical approach to investigating individual differences in endorsement of the code of honor.

    Full Text Available Expansion of Pinus L. (pinyon and Juniperus L. (juniper (P-J trees into sagebrush (Artemisia L. steppe communities can lead to negative effects on hydrology, loss of wildlife habitat, and a decrease in desirable understory vegetation. Tree reduction treatments are often implemented to mitigate these negative effects. In order to prioritize and effectively plan these treatments, rapid, accurate, and inexpensive methods are needed to estimate tree canopy cover at the landscape scale. We used object based image analysis (OBIA software (Feature AnalystTM for ArcMap 10.1®, ENVI Feature Extraction®, and Trimble eCognition Developer 8.2® to extract tree canopy cover using NAIP (National Agricultural Imagery Program imagery. We then compared our extractions with ground measured tree canopy cover (crown diameter and line point intercept on 309 plots across 44 sites in Utah. Extraction methods did not consistently over- or under-estimate ground measured P-J canopy cover except where tree cover was >45%. Estimates of tree canopy cover using OBIA techniques were strongly correlated with estimates using the crown diameter method (r = 0.93 for ENVI, 0.91 for Feature AnalystTM, and 0.92 for eCognition. Tree cover estimates using OBIA techniques had lower correlations with tree cover measurements using the line-point intercept method (r = 0.85 for ENVI, 0.83 for Feature AnalystTM, and 0.83 for eCognition. All software packages accurately and inexpensively extracted P-J canopy cover from NAIP imagery when the imagery was not blurred, and when P-J cover was not mixed with Amelanchier alnifolia (Utah serviceberry and Quercus gambelii (Gambel’s oak, which had similar spectral values as P-J.

  19. Multi-level predictive maintenance for multi-component systems

    Nguyen, Kim-Anh; Do, Phuc; Grall, Antoine

    2015-01-01

    In this paper, a novel predictive maintenance policy with multi-level decision-making is proposed for multi-component system with complex structure. The main idea is to propose a decision-making process considered on two levels: system level and component one. The goal of the decision rules at the system level is to address if preventive maintenance actions are needed regarding the predictive reliability of the system. At component level the decision rules aim at identifying optimally a group of several components to be preventively maintained when preventive maintenance is trigged due to the system level decision. Selecting optimal components is based on a cost-based group improvement factor taking into account the predictive reliability of the components, the economic dependencies as well as the location of the components in the system. Moreover, a cost model is developed to find the optimal maintenance decision variables. A 14-component system is finally introduced to illustrate the use and the performance of the proposed predictive maintenance policy. Different sensitivity analysis are also investigated and discussed. Indeed, the proposed policy provides more flexibility in maintenance decision-making for complex structure systems, hence leading to significant profits in terms of maintenance cost when compared with existing policies. - Highlights: • A predictive maintenance policy for complex structure systems is proposed. • Multi-level decision process based on prognostic results is proposed. • A cost-based group importance measure is introduced for decision-making. • Both positive and negative dependencies between components are investigated. • A cost model and Monte Carlo simulation are developed for optimization process.

    2008-01-01

    A yearly multi-round, multi-period, multi-product transmission rights (TR) auction issuing both point-to-point Financial Transmission Rights (FTRs) and Flow-Gate Rights (FGRs) is studied in this paper. In each round the TR market participants (buyers or sellers) submit their bid or offer prices based on past energy market performance. A Locational Marginal Pricing (LMP) based energy market is assumed. The TR market participants' bid or offer prices reflect their expectation of the average annual LMP differences between withdrawal and injections points for FTRs and of the transmission link capacity prices for FGRs. The TR auction is performed in four rounds; in each round 25% of the entire system capability is awarded. TRs that are awarded in one round are modeled as fixed injections in subsequent rounds. Market participants that have acquired TRs in one round can sell them in subsequent rounds. A market participant can submit bids or offers for on-peak, off-peak or 24-h TRs. A three-area, nine-bus test system with six TR market participants is used for the analysis of the TR auction. (author)

  1. Multi-target consensus circle pursuit for multi-agent systems via a distributed multi-flocking method

    Science.gov (United States)

    Pei, Huiqin; Chen, Shiming; Lai, Qiang

    2016-12-01

    This paper studies the multi-target consensus pursuit problem of multi-agent systems. For solving the problem, a distributed multi-flocking method is designed based on the partial information exchange, which is employed to realise the pursuit of multi-target and the uniform distribution of the number of pursuing agents with the dynamic target. Combining with the proposed circle formation control strategy, agents can adaptively choose the target to form the different circle formation groups accomplishing a multi-target pursuit. The speed state of pursuing agents in each group converges to the same value. A Lyapunov approach is utilised to analyse the stability of multi-agent systems. In addition, a sufficient condition is given for achieving the dynamic target consensus pursuit, and which is then analysed. Finally, simulation results verify the effectiveness of the proposed approaches.

  7. Incomplete Information about Social Preferences Explains Equal Division and Delay in Bargaining

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Two deviations of alternating-offer bargaining behavior from economic theory are observed together, yet have been studied separately. Players who could secure themselves a large surplus share if bargainers were purely self-interested incompletely exploit their advantage. Delay in agreement occurs even if all experimentally controlled information is common knowledge. This paper rationalizes both regularities coherently by modeling heterogeneous social preferences, either self-interest or envy, of one bargaining party as private information in a three period game of bargaining and preference screening and signaling.

    2017-06-01

    Analysts may incorporate many of Melanie Klein's important contributions (e.g., on preoedipal dynamics, envy, and projective identification) without transforming their basic analytic approach. In this paper I argue that adopting the Kleinian notion of unconscious phantasy is transformative. While it is grounded in Freud's thinking and draws out something essential to his work, this notion of phantasy introduces a radical change that defines Kleinian thinking and practice and significantly impacts the analyst's basic clinical approach. This impact and its technical implications in the analytic situation are illustrated and discussed. Copyright © 2017 Institute of Psychoanalysis.

    Not all biases are equivalent, and not all biases are uniformly negative. Two fundamental dimensions differentiate stereotyped groups in cultures across the globe: status predicts perceived competence, and cooperation predicts perceived warmth. Crossing the competence and warmth dimensions, two combinations produce ambivalent prejudices: pitied groups (often traditional women or older people) appear warm but incompetent, and envied groups (often nontraditional women or outsider entrepreneurs) appear competent but cold. Case studies in ambivalent sexism, heterosexism, racism, anti-immigrant biases, ageism, and classism illustrate both the dynamics and the management of these complex but knowable prejudices.

    2014-04-01

    Full Text Available Understanding the role of structure and social aspects regarding heat stress of people in urban areas requires an interdisciplinary scientific approach that connects methods from both natural sciences and social sciences. In this study, we combine three approaches to provide an interdisciplinary analysis of the structure and social components of heat stress in the city of Aachen, Germany. First, we assess the overall spatial structure of the urban heat island using spatially distributed measurements from mobile air temperature recordings on public transport units combined with spatially distributed geo-statistical data. The results indicate that the time of day matters: During the afternoon, areas with a relative low building density, like the industrial area northeast of the inner city, are the warmest, while surfaces in high-building-density areas like the inner city heat up faster during the evening. Second, we combine these measurements with place-based survey data collected in 2010 from residents aged 50 to 92 regarding their individual housing conditions, medical history and social integration to examine the match among heat-based stress of older residents, social conditions and elevated temperatures in their residential quarter. We identify disadvantaged areas for specific already-disadvantaged demographic groups in the city, pointing to a cumulation of inequalities, including heat stress among the most vulnerable. Third, we compare data of biometeorological measurements on urban public squares during the afternoon with results of the micrometeorological model ENVI-met to examine the spatial variability of the inner-city heat load. We complement the modelling results with on-site interviews to evaluate people’s heat perception at the same public places. A simulation shows that additional vegetation would increase thermal comfort at these public places, whereby the heat load assessed using the predicted mean vote (PMV value would

    Full Text Available Computer simulations were performed by ENVI-met model along with physical measurements in two urban squares under hot summer conditions in Isfahan, central Iran. Each scenario concentrated on adding or extending galleries in each square. The results confirmed the role of galleries on thermal conditions; however, it was found that the effectiveness of this strategy depends on the square geometry. It presented higher efficiency for the small square with higher H/W ratio. This solution is advisable for smaller squares and when the peripheral parts are frequently used compared to the middle areas. Galleries are most efficient when allowing enough natural ventilation.

    2014-01-01

    Through an examination of Freud's Lecture 33, "Femininity" (1933), and "Mourning and Melancholia" (1917), the author proposes a reading of Freud's description of the girl becoming a woman. Female development is retold as a melancholic narrative-one in which the girl's entrance into the positive Oedipus is founded on unconscious grievance and unmourned loss of the early relationship with her mother. Castration and penis envy are reconceived as melancholic markers-the manifest content of the subjectivity of refusal, loss, and imagined repair of the early maternal relationship. Lena Dunham's HBO television series Girls is analyzed as an illustration of these theoretical understandings. © 2014 The Psychoanalytic Quarterly, Inc.

    Full Text Available Few years ago in a meeting organized in Paris by the IPS we dealt with Plutarch's treatment of Herodotus’ story regarding the meeting of the Athenian councilman with Croesus of Lydia in his Life of Solon. It is our aim in this occasion to focus on the suppression of two crucial elements from Herodotus’ story, to wit the alleged ‘envy of gods’ and the historian’s cyclic conception of history. Therefore, from an analysis of the reasons behind this elimination, we think that we will be able of understand the consequences for Plutarch's theory of tyche.

    The element of time--the experience of it and the defensive use of it--is explored in conjunction with the use of reversible perspective as a psychotic defense. Clinical material from a long analysis illustrates how a psychotic patient used the reversible perspective, with its static splitting, to abolish the experience of time. When he improved and the reversible perspective became less effective for him, he replaced it with a more dynamic splitting mechanism using time gaps. With further improvement, the patient began to experience the passage of time, and along with it the excruciating pain of separation, envy, and loss.

    The burgeoning role of the analytically prepared nurse psychotherapist in Great Britain. To describe the struggles of nurses in this role and ways this struggle might be lessened. Observations of the author, an analytically prepared nurse psychotherapist-in-training in Great Britain. The role of the nurse psychotherapist with psychoanalytic training is in its infancy in Great Britain. Barriers to the development are both external, from outside the nursing profession, and internal, in the form of sibling rivalry or envy from less prepared nurses. Increased communication among nurses is encouraged so that a shared understanding and mutual respect may result.

    Full Text Available We consider the allocation of a finite number of homogeneous divisible items among three players. Under the assumption that each player assigns a positive value to every item, we develop a simple algorithm that returns a Pareto optimal and equitable allocation. This is based on the tight relationship between two geometric objects of fair division: The Individual Pieces Set (IPS and the Radon-Nykodim Set (RNS. The algorithm can be considered as an extension of the Adjusted Winner procedure by Brams and Taylor to the three-player case, without the guarantee of envy-freeness. (original abstract

    Full Text Available Emotions for Aristotle are emotional faculties in human beings, which can generate susceptibility and cause at some point that judgments be changed and other types of impressions be generated; they are accompanied by pleasure and pain, depending on the moods (that are present at the moment of feeling some emotion. In this article, in addition to developing a reflection on emotions from the Stagirita, there are described some of them and their opposites, which are the most common in all his writings, such as anger and calmness; love and hate; fear and trust; shame and shamelessness; compassion and indignation; and finally, envy and emulation.

  18. Multi-way multi-group segregation and diversity indices.

    Science.gov (United States)

    Gorelick, Root; Bertram, Susan M

    2010-06-01

    How can we compute a segregation or diversity index from a three-way or multi-way contingency table, where each variable can take on an arbitrary finite number of values and where the index takes values between zero and one? Previous methods only exist for two-way contingency tables or dichotomous variables. A prototypical three-way case is the segregation index of a set of industries or departments given multiple explanatory variables of both sex and race. This can be further extended to other variables, such as disability, number of years of education, and former military service. We extend existing segregation indices based on Euclidean distance (square of coefficient of variation) and Boltzmann/Shannon/Theil index from two-way to multi-way contingency tables by including multiple summations. We provide several biological applications, such as indices for age polyethism and linkage disequilibrium. We also provide a new heuristic conceptualization of entropy-based indices. Higher order association measures are often independent of lower order ones, hence an overall segregation or diversity index should be the arithmetic mean of the normalized association measures at all orders. These methods are applicable when individuals self-identify as multiple races or even multiple sexes and when individuals work part-time in multiple industries. The policy implications of this work are enormous, allowing people to rigorously test whether employment or biological diversity has changed.

    1983-01-01

    This paper describes a multi-task monitor program for microprocessors. Although written for the Intel 8085, it incorporates features that would be beneficial for implementation in other microprocessors used in controlling and monitoring experiments and accelerators. The monitor places permanent programs (tasks) arbitrarily located throughout ROM in a priority ordered queue. The programmer is provided with the flexibility to add new tasks or modified versions of existing tasks, without having to comply with previously defined task boundaries or having to reprogram all of ROM. Scheduling of tasks is triggered by timers, outside stimuli (interrupts), or inter-task communications. Context switching time is of the order of tenths of a milllisecond

  4. Multi-bunch Feedback Systems

    International Nuclear Information System (INIS)

    Lonza, M; Schmickler, H

    2014-01-01

    Coupled-bunch instabilities excited by the interaction of the particle beam with its surroundings can seriously limit the performance of circular particle accelerators. These instabilities can be cured by the use of active feedback systems based on sensors capable of detecting the unwanted beam motion and actuators that apply the feedback correction to the beam. Advances in electronic technology now allow the implementation of feedback loops using programmable digital systems. Besides important advantages in terms of flexibility and reproducibility, digital systems open the way to the use of novel diagnostic tools and additional features. We first introduce coupled-bunch instabilities, analysing the equation of motion of charged particles and the different modes of oscillation of a multi-bunch beam, showing how they can be observed and measured. Different types of feedback systems will then be presented as examples of real implementations that belong to the history of multi-bunch feedback systems. The main components of a feedback system and the related issues will also be analysed. Finally, we shall focus on digital feedback systems, their characteristics, and features, as well as on how they can be concretely exploited for both the optimization of feedback performance and for beam dynamics studies

  5. Multi-perpetrator domestic violence.

    Science.gov (United States)

    Salter, Michael

    2014-04-01

    A significant proportion of reports of domestic violence against women involve multiple perpetrators. Although the number of perpetrators has been consistently identified as a measure of abuse severity, only a minority of studies of domestic violence examine the role of multiple offenders. Data on multi-perpetrator domestic violence (MDV) is frequently removed from analysis in domestic violence studies, or multi-perpetrator incidents are treated as single-perpetrator incidents. However, the available research links MDV to negative mental and physical health outcomes, intimate partner homicide, homelessness among women, and severe mental illness and suicidality. This article reviews the available prevalence data on MDV and draws together research on the contexts in which MDV takes place. It highlights two groups that are particularly vulnerable to MDV: (1) girls and women partnered to members of gangs and organized crime groups and (2) girls and women in some ethnic minority communities. While discussions of honor in relation to domestic violence are often racialized in Western media, this article highlights the cross-cultural role of masculine honor in collective violence against women in the working class and impoverished communities of majority cultures as well as in migrant and ethnic minority communities. It is clear that such complex forms of violence present a range of challenges for intervention and treatment and the article emphasizes the need for specialized and coordinated modes of investigation, support, and care.

  7. Staggered multi-field inflation

    International Nuclear Information System (INIS)

    Battefeld, Diana; Battefeld, Thorsten; Davis, Anne-Christine

    2008-01-01

    We investigate multi-field inflationary scenarios with fields that drop out of the model in a staggered fashion. This feature is natural in certain multi-field inflationary setups within string theory; for instance, it can manifest itself when fields are related to tachyons that condense, or inter-brane distances that become meaningless when branes annihilate. Considering a separable potential, and promoting the number of fields to a smooth time dependent function, we derive the formalism to deal with these models at the background and perturbed level, providing general expressions for the scalar spectral index and the running. We recover known results of e.g. a dynamically relaxing cosmological constant in the appropriate limits. We further show that isocurvature perturbations are suppressed during inflation, and so perturbations are adiabatic and nearly Gaussian. The resulting setup might be interpreted as a novel type of warm inflation, readily implemented within string theory and without many of the shortcomings associated with warm inflation. To exemplify the applicability of the formalism we consider three concrete models: assisted inflation with exponential potentials as a simple toy model (a graceful exit becomes possible), inflation from multiple tachyons (a constant decay rate of the number of fields and negligible slow roll contributions turns out to be in good agreement with observations) and inflation from multiple M5-branes within M-theory (a narrow stacking of branes yields a consistent scenario)

  12. Mainstreaming Multi-Risk Approaches into Policy

    Directory of Open Access Journals (Sweden)

    Anna Scolobig

    2017-12-01

    Full Text Available Multi-risk environments are characterized by domino effects that often amplify the overall risk. Those include chains of hazardous events and increasing vulnerability, among other types of correlations within the risk process. The recently developed methods for multi-hazard and risk assessment integrate interactions between different risks by using harmonized procedures based on common metrics. While the products of these assessments, such as multi-hazard and -risk indexes, maps, cascade scenarios, or warning systems provide innovative and effective information, they also pose specific challenges to policy makers and practitioners due to their novel cross-disciplinary aspects. In this paper we discuss the institutional barriers to the adoption of multi-risk approaches, summarizing the results of the fieldwork conducted in Italy and Guadeloupe and of workshops with disaster risk reduction practitioners from eleven European countries. Results show the need for a clear identification of responsibilities for the implementation of multi-risk approaches, as institutional frameworks for risk reduction remain to this day primarily single-risk centered. Authorities are rarely officially responsible for the management of domino effects between e.g., tsunamis and industrial accidents, earthquake and landslides, floods and electricity network failures. Other barriers for the implementation of multi-risk approaches include the limited measures to reduce exposure at the household level, inadequate financial capacities at the local level and limited public-private partnerships, especially in case of interactions between natural and industrial risks. Adapting the scale of institutions to that of multi-risk environments remains a major challenge to better mainstream multi-risk approaches into policy. To address it, we propose a multi-risk governance framework, which includes the phases of observation, social and institutional context analysis, generation of

  13. Water erosion on areas planted to potato in Tucumán by climate change.

    Rios Caceres, Arq. Estela Alejandra; Rios, Victor Hugo; Lucena, Valeria; Guyot, Elia

    Climate changes, monitored by experts from all over the world, have been a matter of con-sciousness raising about the impacts global warming will have on all areas of interest on the planet. The foreseeable direct impacts expected from this evidence are clear: fewer water reserves for agricultural, industrial and urban use; acceleration of desertification processess; destruction of freshwater ecosystems; ecosystem modification due to a drop in rainfall and an increase in temperature to the north of the XI. Region; disappearance of large areas of snow and ice; severe erosion of unprotected basins; reduced water availability for plants in non irrigated land, due to an increase in rain fall intensity. Climate changes demand from the Argentine society a much greater effort than it has been made up to now to mitigate the impacts on our territory and its inhabitants. Potato crop is of a great economic importance in the agricultural GDP of the province of Tucumán (4th place), the geographic location of its production area a is a fragile agro-ecosystem and for this reason the management of water erosion problems is essential. Therefore the aim of this work is to improve potatoe crop irrigation management through information from satellites combined with farm practice. The digital terrain model was obtained from ASTER images. Irrigation practices were followed by an irrigation management software (FAO) and satellite image processing (ENVI). Preliminary results of this experience enabled, through a multi temporal study, the observation of the evolution of crops and irriga-tion practices rescheduling for next season reducing detected water erosion and economically optimizing productivity.

    Hyperspectral imaging technologies have shown great promise for biomedical applications. These techniques have been especially useful for detection of molecular events and characterization of cell, tissue, and biomaterial composition. Unfortunately, hyperspectral imaging technologies have been slow to translate to clinical devices - likely due to increased cost and complexity of the technology as well as long acquisition times often required to sample a spectral image. We have demonstrated that hyperspectral imaging approaches which scan the fluorescence excitation spectrum can provide increased signal strength and faster imaging, compared to traditional emission-scanning approaches. We have also demonstrated that excitation-scanning approaches may be able to detect spectral differences between colonic adenomas and adenocarcinomas and normal mucosa in flash-frozen tissues. Here, we report feasibility results from using excitation-scanning hyperspectral imaging to screen pairs of fresh tumoral and nontumoral colorectal tissues. Tissues were imaged using a novel hyperspectral imaging fluorescence excitation scanning microscope, sampling a wavelength range of 360-550 nm, at 5 nm increments. Image data were corrected to achieve a NIST-traceable flat spectral response. Image data were then analyzed using a range of supervised and unsupervised classification approaches within ENVI software (Harris Geospatial Solutions). Supervised classification resulted in >99% accuracy for single-patient image data, but only 64% accuracy for multi-patient classification (n=9 to date), with the drop in accuracy due to increased false-positive detection rates. Hence, initial data indicate that this approach may be a viable detection approach, but that larger patient sample sizes need to be evaluated and the effects of inter-patient variability studied.

  15. A Multispectral Micro-Imager for Lunar Field Geology

    Nunez, Jorge; Farmer, Jack; Sellar, Glenn; Allen, Carlton

    2009-01-01

    Field geologists routinely assign rocks to one of three basic petrogenetic categories (igneous, sedimentary or metamorphic) based on microtextural and mineralogical information acquired with a simple magnifying lens. Indeed, such observations often comprise the core of interpretations of geological processes and history. The Multispectral Microscopic Imager (MMI) uses multi-wavelength, light-emitting diodes (LEDs) and a substrate-removed InGaAs focal-plane array to create multispectral, microscale reflectance images of geological samples (FOV 32 X 40 mm). Each pixel (62.5 microns) of an image is comprised of 21 spectral bands that extend from 470 to 1750 nm, enabling the discrimination of a wide variety of rock-forming minerals, especially Fe-bearing phases. MMI images provide crucial context information for in situ robotic analyses using other onboard analytical instruments (e.g. XRD), or for the selection of return samples for analysis in terrestrial labs. To further assess the value of the MMI as a tool for lunar exploration, we used a field-portable, tripod-mounted version of the MMI to image a variety of Apollo samples housed at the Lunar Experiment Laboratory, NASA s Johnson Space Center. MMI images faithfully resolved the microtextural features of samples, while the application of ENVI-based spectral end member mapping methods revealed the distribution of Fe-bearing mineral phases (olivine, pyroxene and magnetite), along with plagioclase feldspars within samples. Samples included a broad range of lithologies and grain sizes. Our MMI-based petrogenetic interpretations compared favorably with thin section-based descriptions published in the Lunar Sample Compendium, revealing the value of MMI images for astronaut and rover-mediated lunar exploration.

    The dawn of 21st century is marked by severe and unpredictable natural and man - made hazards and disasters linked as to climate change as to human impact on environment. To study their effects on natural landscapes and protected areas it is important to perform, in some restrict regime protected areas, a continuous monitoring. Earth observation by satellites is one of the most promising instruments for this as it has the necessary time, spatial, and spectral resolution for this as well as it provides for non-contact estimation of the overall condition of the environment. This study presents preliminary results of fire scars area estimation on the territory of Bistrishko Branishte UNESCO Man and Biosphere (MAB) reserve in Vitosha Mountain, Bulgaria using CHRIS/PROBA satellite data. During the summer and early autumn of 2012 CHRIS/PROBA instrument was tasked to perform a series of acquisitions with a view to study the vegetation structure. The study uses two CHRIS/PROBA scenes acquired subsequently on 22 June 2012 and on 28 September 2012. The wildfire, which effects are studied, took place during the first two weeks of July 2012. After it was settled the second acquisition of CHRIS/PROBA instrument made possible the analysis of the post fire situation. The methods used for the study are the standard methods for image change detection based on spectral data employed in ENVI software (Academic license). In order to perform the change detection, the CHRIS/PROBA source data was geometrically and atmospherically corrected as well as co-registered. The multi angle product of CHRIS/PROBA Mode 1, consisting of 5 images, was used to check to what extent the five viewing angles affect the area estimation of the fire scars in the mountainous area following same procedures. The results from the analysis shown that almost 60 hectares from the coniferous vegetation (dead and healthy tree stands) were devastated by the wildfire.

    This paper proposed an alarm-monitoring system for people based on multi-agent using maps. The system monitors the users physical context using their mobile phone. The agents on the mobile phones are responsible for collecting, processing and sending data to the server. They can determine the parameters of their environment by sensors. The data are processed and sent to the server. On the other side, a set of agents on server can store this data and check the preconditions of the restrictions associated with the user, in order to trigger the appropriate alarms. These alarms are sent not only to the user who is alarmed to avoid the appeared restriction, but also to his supervisor. The proposed system is a general purpose alarm system that can be used in different critical application areas. It has been applied for monitoring the workers of radiation sites. However, these workers can do their activity tasks in the radiation environments safely

    1998-12-31

    A method for modeling multi-lateral wells by using a computational scheme embedded in a general-purpose, finite difference simulator was described. The calculation of wellbore pressure profile for each lateral included the frictional pressure drop along the wellbore and proper fluid mixing at lateral connection points. To obtain a good production profile the Beggs and Brill correlation, a homogenous flow model, and the model proposed by Ouyang et al, which includes an acceleration term and accounts for the lubrication effect due to radial influx, were implemented. Well performance prediction results were compared using the three models. The impact of different tubing sizes on the well performance and the prediction contribution from each lateral were also studied. Results of the study in the hypothetical example and under normal field operating conditions were reviewed. 7 refs., 10 tabs., 3 figs.

    The present paper analyses both managerial and program efficiencies of Lithuanian family farms, in the tradition of Charnes et al. (Manag Sci 27(6):668–697, 1981) but with the important difference that multi-directional efficiency analysis rather than the traditional data envelopment analysis...... approach is used to estimate efficiency. This enables a consideration of input-specific efficiencies. The study shows clear differences between the efficiency scores on the different inputs as well as between the farm types of crop, livestock and mixed farms respectively. We furthermore find that crop...... farms have the highest program efficiency, but the lowest managerial efficiency and that the mixed farms have the lowest program efficiency (yet not the highest managerial efficiency)....

    1996-01-01

    An important issue in the manufacture of multi-segment undulators as a source of synchrotron radiation or as a free-electron laser (FEL) is the phasing between successive segments. The state of the art is briefly reviewed, after which a novel pure permanent magnet phasing section that is passive and does not require any current is presented. The phasing section allows the introduction of a 6 mm longitudinal gap between each segment, resulting in complete mechanical independence and reduced magnetic interaction between segments. The tolerance of the longitudinal positioning of one segment with respect to the next is found to be 2.8 times lower than that of conventional phasing. The spectrum at all gaps and useful harmonics is almost unchanged when compared with a single-segment undulator of the same total length. (au) 3 refs

    Multi-function fingers that are able to handle multiple workpieces are crucial in improvement of a robot workcell. Design automation of multi-function fingers is highly demanded by robot industries to overcome the current iterative, time consuming and complex manual design process. However, the existing approaches for the multi-function finger design automation are unable to entirely meet the robot industries’ need. This paper proposes a generic approach for design automation of multi-function fingers. The proposed approach completely automates the design process and requires no expert skill. In addition, this approach executes the design process much faster than the current manual process. To validate the approach, multi-function fingers are successfully designed for two case studies. Further, the results are discussed and benchmarked with existing approaches.

    2015-09-01

    The Adaptive Multi-scale Simulation Infrastructure (AMSI) is a set of libraries and tools developed to support the development, implementation, and execution of general multimodel simulations. Using a minimal set of simulation meta-data AMSI allows for minimally intrusive work to adapt existent single-scale simulations for use in multi-scale simulations. Support for dynamic runtime operations such as single- and multi-scale adaptive properties is a key focus of AMSI. Particular focus has been spent on the development on scale-sensitive load balancing operations to allow single-scale simulations incorporated into a multi-scale simulation using AMSI to use standard load-balancing operations without affecting the integrity of the overall multi-scale simulation.

  1. Multi-monopoles and magnetic bags

    International Nuclear Information System (INIS)

    Bolognesi, Stefano

    2006-01-01

    By analogy with the multi-vortices, we show that also multi-monopoles become magnetic bags in the large n limit. This simplification allows us to compute the spectrum and the profile functions by requiring the minimization of the energy of the bag. We consider in detail the case of the magnetic bag in the limit of vanishing potential and we find that it saturates the Bogomol'nyi bound and there is an infinite set of different shapes of allowed bags. This is consistent with the existence of a moduli space of solutions for the BPS multi-monopoles. We discuss the string theory interpretation of our result and also the relation between the 't Hooft large n limit of certain supersymmetric gauge theories and the large n limit of multi-monopoles. We then consider multi-monopoles in the cosmological context and provide a mechanism that could lead to their production

    2017-04-01

    Non-negative matrix factorization based multi-view clustering algorithms have shown their competitiveness among different multi-view clustering algorithms. However, non-negative matrix factorization fails to preserve the locally geometrical structure of the data space. In this paper, we propose a multi-manifold regularized non-negative matrix factorization framework (MMNMF) which can preserve the locally geometrical structure of the manifolds for multi-view clustering. MMNMF incorporates consensus manifold and consensus coefficient matrix with multi-manifold regularization to preserve the locally geometrical structure of the multi-view data space. We use two methods to construct the consensus manifold and two methods to find the consensus coefficient matrix, which leads to four instances of the framework. Experimental results show that the proposed algorithms outperform existing non-negative matrix factorization based algorithms for multi-view clustering. Copyright © 2017 Elsevier Ltd.

  4. Challenges and opportunities of multi-disciplinary, multi-national and multi-sectoral projects

    Science.gov (United States)

    Reitz, Anja; Hamann, Kristin

    2017-04-01

    Collaborative research projects e.g. funded or supported by the European Commission are by nature multi-national. Often EU calls bring together different scientific communities to jointly tackle challenges that can only be addressed through the convergence of previously separated disciplines in one research consortium. Some work programmes even necessitate to team up as different disciplines as natural sciences, social science, legal science and economic science. Examples for such multi- national, -disciplinary and - sectoral projects are the EU projects ECO2 (FP7, concluded), AtlantOS (H2020) and MiningImpact (JPI Oceans). Project managers of such projects need to develop skills beyond the common technical and management skills namely go into the domain of partners and stakeholders psychology and be able to maintain different perspectives on communication and interaction needs regarding cultural-, discipline- and sectoral background. Accordingly, the project manager has besides his or her technical role as manager at least three further roles: that of a communicator, that of a mediator and that of a person convincing partners of the necessary and selling the project products to the stakeholders. As the typical project manager has not too much power and authority by his or her position he or she has to use the power of smart communication and persuasion to overcome potential dissension between disciplines, national reservation or potential conflicts regarding different sectoral views. Accordingly, the project manager of such complex projects would try to arrange the ideal working environment by considering cultural feel, the cooperation of disciplines, information and the control of resources. The way he or she develops such ideal working environment is by reflection of past, present and future experiences/needs.

  5. Multi-headed comparatives in Portuguese

    Directory of Open Access Journals (Sweden)

    Rui Marques

    2005-06-01

    Full Text Available This paper aims at offering a global picture of the subtype of comparative constructions known as ‘multi-headed comparatives’ (from the fact that they exhibit more than one comparative operator in semantic interdependence. As a prerequisite to the fulfilment of his goal, an attempt will be made to clarify the scope of the notion ‘comparative construction’ and to draw a general typology of such constructions. The boundaries of the notion ‘comparative construction’ are defined by contrasting a “genuine” class of comparative constructions with others that hold some syntactic or semantic resemblance to them. Different typologies will be taken into consideration. As for multi-headed comparatives, even though different examples of these constructions have been identified in the scarce literature on the matter, the discussion on their syntactic patterns and meaning is still embryonic. This paper suggests that the expressive power of these comparatives, which seem to provide a particular strategy of information compression, is higher than has been assumed. Four sub-kinds of multi-headed comparatives are identified, based on meaning differences, namely: multi-headed comparatives with a distributive reading, multi-headed comparatives with a cumulative reading, multi-headed comparatives with a comparison of ‘ratios’ reading, and multi-headed comparatives with a comparison of differences reading. While resorting to some classic English examples, the object language will predominantly be Portuguese.

  6. Simulation-optimization framework for multi-site multi-season hybrid stochastic streamflow modeling

    Science.gov (United States)

    Srivastav, Roshan; Srinivasan, K.; Sudheer, K. P.

    2016-11-01

    A simulation-optimization (S-O) framework is developed for the hybrid stochastic modeling of multi-site multi-season streamflows. The multi-objective optimization model formulated is the driver and the multi-site, multi-season hybrid matched block bootstrap model (MHMABB) is the simulation engine within this framework. The multi-site multi-season simulation model is the extension of the existing single-site multi-season simulation model. A robust and efficient evolutionary search based technique, namely, non-dominated sorting based genetic algorithm (NSGA - II) is employed as the solution technique for the multi-objective optimization within the S-O framework. The objective functions employed are related to the preservation of the multi-site critical deficit run sum and the constraints introduced are concerned with the hybrid model parameter space, and the preservation of certain statistics (such as inter-annual dependence and/or skewness of aggregated annual flows). The efficacy of the proposed S-O framework is brought out through a case example from the Colorado River basin. The proposed multi-site multi-season model AMHMABB (whose parameters are obtained from the proposed S-O framework) preserves the temporal as well as the spatial statistics of the historical flows. Also, the other multi-site deficit run characteristics namely, the number of runs, the maximum run length, the mean run sum and the mean run length are well preserved by the AMHMABB model. Overall, the proposed AMHMABB model is able to show better streamflow modeling performance when compared with the simulation based SMHMABB model, plausibly due to the significant role played by: (i) the objective functions related to the preservation of multi-site critical deficit run sum; (ii) the huge hybrid model parameter space available for the evolutionary search and (iii) the constraint on the preservation of the inter-annual dependence. Split-sample validation results indicate that the AMHMABB model is

  7. Adhesion and multi-materials

    International Nuclear Information System (INIS)

    Schultz, J.

    1997-01-01

    Adhesion is a multidisciplinary science relevant to many practical fields. The main application of adhesion is bonding by adhesives. This technique is widely used in the industrial world and more specifically in the advanced technical domains. Adhesion is also involved in multi-component materials such as coatings, multilayer materials, polymer blends, composite materials... The multidisciplinary aspect of adhesion is well demonstrated by considering the wide variety of concepts, models and theories proposed for its description. An example of the adhesion between a fiber and a matrix in a composite material will lead to a general model relating the molecular properties of the interface to its capacity of stress transfer and hence to the macroscopic mechanical properties of the composite. This relationship is valid whatever the fiber (glass, carbon, polymeric) or the polymer matrix (thermoplastics, thermosetting). Any deviation from this model can be attributed to the existence of an interfacial zone or interphase exhibiting properties, mainly mechanical properties, different from the bulk matrix. Two examples are examined: the first one deals with the creation of a trans crystalline interphase in a semi-crystalline thermoplastic matrix and the second one is concerned with the formation of a pseudo glassy interphase in an elastomer matrix. These examples stress the need for complementary approaches in the understanding of adhesion phenomena at different levels of knowledge, from molecular to macroscopic. They also show how important it is to understand the mechanisms of formation of inter phases in order to be able to master the performance of multicomponent materials. (Author)

    Multi-Gas Monitor is a flight experiment, a technology demonstration to test the ability of tunable diode laser spectroscopy based instrument to stay in calibration long term and follow events and dynamics occurring with the cabin atmosphere. MGM measures 4 gases: oxygen, carbon monoxide, ammonia and water vapor, as well as temperature and pressure. This month marked one year of successful and continuous MGM operation on ISS. The crew successfully tested the ammonia channel using a commercially available inhalant. MGM has detected some interesting dynamics inside Japanese Experiment Module (JEM) as a result of CO2 thruster firings from the SPHERES/RINGS payload and water spikes from dry out cycling of the JEM heat exchangers. Results to date have given us high confidence in the technology such that we believe this could have applications in the energy and medical sectors. This presentation will summarize the testing and results of the unit on ISS and suggest areas of use within the energy and medical arenas.

    Last decade after our proposal of the 'Carbon Alloys' concept, many different kinds of Carbon Alloys, such as carbon nanotubes, carbon nanofibers, graphene sheet with magnetism, semi-conducting BCN compounds, graphite intercalation compounds, exfoliated carbon fiber, etc. have been found and developed. To extend the concept further, it is important to make it into intelligent materials by incorporating multiple functions. One example of the multi-functionalization is the development of homo-atomic Carbon Alloys from glassy carbon (GC) that exhibits high electrical conductivity and low gas permeability after treatment at critical conditions. Glassy carbon underwent metamorphosis to graphite spheres at HIP condition, and improved resistance to oxidation after alloying with Ta. The other one is shape utilization of the nano-sized carbon by understanding the effect of its large surfaces or interfaces in nanotechnology treatment. Recently carbon nanofiber was produced by polymer blend technology (PB) which was proposed by Prof. A. Oya during the Carbon Alloy project and progressed into intelligent carbon nanofiber (CNF) materials. CNF is combined into the polymer composites which is a candidate material for the bipolar separator in fuel cell. The superior properties, i.e., high electrical conductivity, high modulus, high strength, etc., of the CNF is being utilized in the preparation of this polymer composite.

  10. Multi-language naming game

    Zhou, Jianfeng; Lou, Yang; Chen, Guanrong; Tang, Wallace K. S.

    2018-04-01

    Naming game is a simulation-based experiment used to study the evolution of languages. The conventional naming game focuses on a single language. In this paper, a novel naming game model named multi-language naming game (MLNG) is proposed, where the agents are different-language speakers who cannot communicate with each other without a translator (interpreter) in between. The MLNG model is general, capable of managing k different languages with k ≥ 2. For illustration, the paper only discusses the MLNG with two different languages, and studies five representative network topologies, namely random-graph, WS small-world, NW small-world, scale-free, and random-triangle topologies. Simulation and analysis results both show that: 1) using the network features and based on the proportion of translators the probability of establishing a conversation between two or three agents can be theoretically estimated; 2) the relationship between the convergence speed and the proportion of translators has a power-law-like relation; 3) different agents require different memory sizes, thus a local memory allocation rule is recommended for saving memory resources. The new model and new findings should be useful for further studies of naming games and for better understanding of languages evolution from a dynamical network perspective.

  11. Multi-Hop Link Capacity of Multi-Route Multi-Hop MRC Diversity for a Virtual Cellular Network

    Science.gov (United States)

    Daou, Imane; Kudoh, Eisuke; Adachi, Fumiyuki

    In virtual cellular network (VCN), proposed for high-speed mobile communications, the signal transmitted from a mobile terminal is received by some wireless ports distributed in each virtual cell and relayed to the central port that acts as a gateway to the core network. In this paper, we apply the multi-route MHMRC diversity in order to decrease the transmit power and increase the multi-hop link capacity.

    2013-07-16

    A multi-channel polarized thermal emitter (PTE) is presented. The multi-channel PTE can emit polarized thermal radiation without using a polarizer at normal emergence. The multi-channel PTE consists of two layers of metallic gratings on a monolithic and homogeneous metallic plate. It can be fabricated by a low-cost soft lithography technique called two-polymer microtransfer molding. The spectral positions of the mid-infrared (MIR) radiation peaks can be tuned by changing the periodicity of the gratings and the spectral separation between peaks are tuned by changing the mutual angle between the orientations of the two gratings.

    This book provides a description of advanced multi-agent and artificial intelligence technologies for the modeling and simulation of complex systems, as well as an overview of the latest scientific efforts in this field. A complex system features a large number of interacting components, whose aggregate activities are nonlinear and self-organized. A multi-agent system is a group or society of agents which interact with others cooperatively and/or competitively in order to reach their individual or common goals. Multi-agent systems are suitable for modeling and simulation of complex systems, which is difficult to accomplish using traditional computational approaches.

    Synthetic aperture radar (SAR) is a well-known remote sensing technique, but conventional single-antenna SAR is inherently limited by the minimum antenna area constraint. Although there are still technical issues to overcome, multi-antenna SAR offers many benefits, from improved system gain to increased degrees-of-freedom and system flexibility. Multi-Antenna Synthetic Aperture Radar explores the potential and challenges of using multi-antenna SAR in microwave remote sensing applications. These applications include high-resolution imaging, wide-swath remote sensing, ground moving target indica

    In multi-instance learning (MIL), the relations among instances in a bag convey important contextual information in many applications. Previous studies on MIL either ignore such relations or simply model them with a fixed graph structure so that the overall performance inevitably degrades in complex environments. To address this problem, this paper proposes a novel multi-view multi-instance learning algorithm (MIL) that combines multiple context structures in a bag into a unified framework. The novel aspects are: (i) we propose a sparse -graph model that can generate different graphs with different parameters to represent various context relations in a bag, (ii) we propose a multi-view joint sparse representation that integrates these graphs into a unified framework for bag classification, and (iii) we propose a multi-view dictionary learning algorithm to obtain a multi-view graph dictionary that considers cues from all views simultaneously to improve the discrimination of the MIL. Experiments and analyses in many practical applications prove the effectiveness of the M IL.

  18. Interactive Approach for Multi-Level Multi-Objective Fractional Programming Problems with Fuzzy Parameters

    Directory of Open Access Journals (Sweden)

    M.S. Osman

    2018-03-01

    Full Text Available In this paper, an interactive approach for solving multi-level multi-objective fractional programming (ML-MOFP problems with fuzzy parameters is presented. The proposed interactive approach makes an extended work of Shi and Xia (1997. In the first phase, the numerical crisp model of the ML-MOFP problem has been developed at a confidence level without changing the fuzzy gist of the problem. Then, the linear model for the ML-MOFP problem is formulated. In the second phase, the interactive approach simplifies the linear multi-level multi-objective model by converting it into separate multi-objective programming problems. Also, each separate multi-objective programming problem of the linear model is solved by the ∊-constraint method and the concept of satisfactoriness. Finally, illustrative examples and comparisons with the previous approaches are utilized to evince the feasibility of the proposed approach.

    2015-03-27

    In this thesis we propose new methods in multi-qubit multi-mode circuit quantum electrodynamics (circuit-QED) architectures. First we describe a direct parity measurement method for three qubits, which can be realized in 2D circuit-QED with a possible extension to four qubits in a 3D circuit-QED setup for the implementation of the surface code. In Chapter 3 we show how to derive Hamiltonians and compute relaxation rates of the multi-mode superconducting microwave circuits consisting of single Josephson junctions using an exact impedance synthesis technique (the Brune synthesis) and applying previous formalisms for lumped element circuit quantization. In the rest of the thesis we extend our method to multi-junction (multi-qubit) multi-mode circuits through the use of state-space descriptions which allows us to quantize any multiport microwave superconducting circuit with a reciprocal lossy impedance response.

    Multi-factor authentication using quantum communication ("QC") includes stages for enrollment and identification. For example, a user enrolls for multi-factor authentication that uses QC with a trusted authority. The trusted authority transmits device factor information associated with a user device (such as a hash function) and user factor information associated with the user (such as an encrypted version of a user password). The user device receives and stores the device factor information and user factor information. For multi-factor authentication that uses QC, the user device retrieves its stored device factor information and user factor information, then transmits the user factor information to the trusted authority, which also retrieves its stored device factor information. The user device and trusted authority use the device factor information and user factor information (more specifically, information such as a user password that is the basis of the user factor information) in multi-factor authentication that uses QC.

  3. Euclidean supergravity and multi-centered solutions

    Directory of Open Access Journals (Sweden)

    W.A. Sabra

    2017-04-01

    Full Text Available In ungauged supergravity theories, the no-force condition for BPS states implies the existence of stable static multi-centered solutions. The first solutions to Einstein–Maxwell theory with a positive cosmological constant describing an arbitrary number of charged black holes were found by Kastor and Traschen. Generalisations to five and higher dimensional theories were obtained by London. Multi-centered solutions in gauged supergravity, even with time-dependence allowed, have yet to be constructed. In this letter we construct supersymmetry-preserving multi-centered solutions for the case of D=5, N=2 Euclidean gauged supergravity coupled to an arbitrary number of vector multiplets. Higher dimensional Einstein–Maxwell multi-centered solutions are also presented.

    A multi-Peta-watt laser inside the 'Ligne d'integration laser' building is studied. We present simulations of the different amplification stages to reach broadband 10 kJ pulses in order to obtain a multi-Peta-watt laser beam. The results for preamplifier and power amplifier are detailed. Challenges of a multi-Peta-watt system are to increase the limit of compressed energy an order of magnitude, to perform a focal spot around 100 μm for Fast Ignitor applications, and to provide a temporal contrast better than 10 10 , for X-ray laser and plasma interaction applications. These first 1-D calculations are helpful for the design of a multi-Peta-watt laser. (authors)

    2003-05-01

    Development of multi-photon phosphor materials for discharge lamps represents a goal that would achieve up to a doubling of discharge (fluorescent) lamp efficacy. This report reviews the existing literature on multi-photon phosphors, identifies obstacles in developing such phosphors, and recommends directions for future research to address these obstacles. To critically examine issues involved in developing a multi-photon phosphor, the project brought together a team of experts from universities, national laboratories, and an industrial lamp manufacturer. Results and findings are organized into three categories: (1) Multi-Photon Systems and Processes, (2) Chemistry and Materials Issues, and (3) Concepts and Models. Multi-Photon Systems and Processes: This category focuses on how to use our current understanding of multi-photon phosphor systems to design new phosphor systems for application in fluorescent lamps. The quickest way to develop multi-photon lamp phosphors lies in finding sensitizer ions for Gd{sup 3+} and identifying activator ions to red shift the blue emission from Pr{sup 3+} due to the {sup 1}S{sub 0} {yields} {sup 1}I{sub 6} transition associated with the first cascading step. Success in either of these developments would lead to more efficient fluorescent lamps. Chemistry and Materials Issues: The most promising multi-photon phosphors are found in fluoride hosts. However, stability of fluorides in environments typically found in fluorescent lamps needs to be greatly improved. Experimental investigation of fluorides in actual lamp environments needs to be undertaken while working on oxide and oxyfluoride alternative systems for backup. Concepts and Models: Successful design of a multi-photon phosphor system based on cascading transitions of Gd{sup 3+} and Pr{sup 3+} depends critically on how the former can be sensitized and the latter can sensitize an activator ion.

  4. Multi-criteria objective based climate change impact assessment for multi-purpose multi-reservoir systems

    Science.gov (United States)

    Müller, Ruben; Schütze, Niels

    2014-05-01

    Water resources systems with reservoirs are expected to be sensitive to climate change. Assessment studies that analyze the impact of climate change on the performance of reservoirs can be divided in two groups: (1) Studies that simulate the operation under projected inflows with the current set of operational rules. Due to non adapted operational rules the future performance of these reservoirs can be underestimated and the impact overestimated. (2) Studies that optimize the operational rules for best adaption of the system to the projected conditions before the assessment of the impact. The latter allows for estimating more realistically future performance and adaption strategies based on new operation rules are available if required. Multi-purpose reservoirs serve various, often conflicting functions. If all functions cannot be served simultaneously at a maximum level, an effective compromise between multiple objectives of the reservoir operation has to be provided. Yet under climate change the historically preferenced compromise may no longer be the most suitable compromise in the future. Therefore a multi-objective based climate change impact assessment approach for multi-purpose multi-reservoir systems is proposed in the study. Projected inflows are provided in a first step using a physically based rainfall-runoff model. In a second step, a time series model is applied to generate long-term inflow time series. Finally, the long-term inflow series are used as driving variables for a simulation-based multi-objective optimization of the reservoir system in order to derive optimal operation rules. As a result, the adapted Pareto-optimal set of diverse best compromise solutions can be presented to the decision maker in order to assist him in assessing climate change adaption measures with respect to the future performance of the multi-purpose reservoir system. The approach is tested on a multi-purpose multi-reservoir system in a mountainous catchment in Germany. A

    NASA is rapidly moving towards the use of spatially distributed multiple satellites operating in near Earth orbit and Deep Space. Effective operation of such multi-satellite constellations raises many key research issues. In particular, the satellites will be required to cooperate with each other as a team that must achieve common objectives with a high degree of autonomy from ground based operations. The multi-agent research community has made considerable progress in investigating the challenges of realizing such teamwork. In this report, we discuss some of the teamwork issues that will be faced by multi-satellite operations. The basis of the discussion is a particular proposed mission, the Magnetospheric MultiScale mission to explore Earth's magnetosphere. We describe this mission and then consider how multi-agent technologies might be applied in the design and operation of these missions. We consider the potential benefits of these technologies as well as the research challenges that will be raised in applying them to NASA multi-satellite missions. We conclude with some recommendations for future work.

    In this paper, a novel L2-SVM based classifier Multi-view L2-SVM is proposed to address multi-view classification tasks. The proposed Multi-view L2-SVM classifier does not have any bias in its objective function and hence has the flexibility like μ-SVC in the sense that the number of the yielded support vectors can be controlled by a pre-specified parameter. The proposed Multi-view L2-SVM classifier can make full use of the coherence and the difference of different views through imposing the consensus among multiple views to improve the overall classification performance. Besides, based on the generalized core vector machine GCVM, the proposed Multi-view L2-SVM classifier is extended into its GCVM version MvCVM which can realize its fast training on large scale multi-view datasets, with its asymptotic linear time complexity with the sample size and its space complexity independent of the sample size. Our experimental results demonstrated the effectiveness of the proposed Multi-view L2-SVM classifier for small scale multi-view datasets and the proposed MvCVM classifier for large scale multi-view datasets.

  8. Generalized modeling of multi-component vaporization/condensation phenomena for multi-phase-flow analysis

    International Nuclear Information System (INIS)

    Morita, K.; Fukuda, K.; Tobita, Y.; Kondo, Sa.; Suzuki, T.; Maschek, W.

    2003-01-01

    A new multi-component vaporization/condensation (V/C) model was developed to provide a generalized model for safety analysis codes of liquid metal cooled reactors (LMRs). These codes simulate thermal-hydraulic phenomena of multi-phase, multi-component flows, which is essential to investigate core disruptive accidents of LMRs such as fast breeder reactors and accelerator driven systems. The developed model characterizes the V/C processes associated with phase transition by employing heat transfer and mass-diffusion limited models for analyses of relatively short-time-scale multi-phase, multi-component hydraulic problems, among which vaporization and condensation, or simultaneous heat and mass transfer, play an important role. The heat transfer limited model describes the non-equilibrium phase transition processes occurring at interfaces, while the mass-diffusion limited model is employed to represent effects of non-condensable gases and multi-component mixture on V/C processes. Verification of the model and method employed in the multi-component V/C model of a multi-phase flow code was performed successfully by analyzing a series of multi-bubble condensation experiments. The applicability of the model to the accident analysis of LMRs is also discussed by comparison between steam and metallic vapor systems. (orig.)

    Damage to the ventromedial prefrontal cortex (VMPFC) impairs concern for other people, as reflected in the dysfunctional real-life social behavior of patients with such damage, as well as their abnormal performances on tasks ranging from moral judgment to economic games. Despite these convergent data, we lack a formal model of how, and to what degree, VMPFC lesions affect an individual’s social decision-making. Here we provide a quantification of these effects using a formal economic model of choice that incorporates terms for the disutility of unequal payoffs, with parameters that index behaviors normally evoked by guilt and envy. Six patients with focal VMPFC lesions participated in a battery of economic games that measured concern about payoffs to themselves and to others: dictator, ultimatum, and trust games. We analyzed each task individually, but also derived estimates of the guilt and envy parameters from aggregate behavior across all of the tasks. Compared to control subjects, the patients donated significantly less and were less trustworthy, and overall our model found a significant insensitivity to guilt. Despite these abnormalities, the patients had normal expectations about what other people would do, and they also did not simply generate behavior that was more noisy. Instead, the findings argue for a specific insensitivity to guilt, an abnormality that we suggest characterizes a key contribution made by the VMPFC to social behavior. PMID:19228971

  11. Transgenerational metamorphosis in Shakespeare’s Winter’s tale and the eurozone crisis

    Directory of Open Access Journals (Sweden)

    Gerald Wooster

    2014-09-01

    Full Text Available Shakespeare’s The Winter’s Tale – set in Palermo, and also Bohemia - suggests that where there is close affection and love there also may be more exposure to envy, jealousy, uncontrolled anger,attempts to punish, and guilt.

    An affordable vertical house, which is known as rusun in Indonesian term becomes the utopia of a compact city. The rusun to be the main actor contributing to the creation of liveable comfort in dense areas by relocating squatters and slum inhabitants to better living places. Technical guidelines and building standards play a major role in a building’s environmental impact. These standards will be reviewed based on their impact on building performance. There are two prototypes of rusun referenced in 05/PRT/M/2007, and the assessment of these prototypes has been done by using ENVi-met. The meteorological data for the ENVI-met configuration input is adapted to the same weather and climate conditions taken from the data measured on June 13th, 2012. The analysis of this assessment will focus on building orientation, building length, building height, and also the microclimate which is impacted by these prototypes. Based on the assessment, it is recommended that the layout of outdoor space on the north side should provide as much green coverage as possible, either for shadowing or for the benefit of its albedo. The simulation shows that building ratio of 1:3 produces higher wind speed, which also controls air temperature and humidity.

    Full Text Available Power posing, the adoption of open and powerful postures, has effects that parallel those of actual social power. This study explored the social evaluation of adopting powerful versus powerless body postures in men and women regarding perceived warmth, competence, and the likelihood of eliciting admiration, envy, pity, and contempt. Previous findings suggest that the display of power by women may have side effects due to gender stereotyping, namely reduced warmth ratings and negative emotional reactions. An experiment (N = 2,473 asked participants to rate pictures of men and women who adopted high-power or low-power body postures. High-power posers were rated higher on competence, admiration, envy, and contempt compared to low-power posers, whereas the opposite was true for pity. There was no impact of power posing on perceived warmth. Contrary to expectations, the poser’s gender did not moderate any of the effects. These findings suggest that nonverbal displays of power do influence fundamental dimensions of social perception and their accompanying emotional reactions but result in comparably positive and negative evaluations for both genders.

  17. A reconsideration of object choice in women: phallus or fallacy.

    Science.gov (United States)

    Frenkel, R S

    1996-01-01

    Within the context of Freud's theory of instinctual drives, analytic data from three female patients are presented which refute his concept that penis envy is the basis for female object choice. Contrary to Freud's theory, these patients did not feel their genitalia or genital arousal were inadequate. Rather, they believed their genital sexuality and fantasies were powerful and gratifying, but dangerous and bad. Their subsequent guilt and fears led secondarily to their defensive wish to have a penis to avoid their core conflicts; their penis envy was pathological. The data unequivocally demonstrate that the clitoris is not an inferior organ, but is the locus for the initiation of intense pleasure and occasional orgasm as early as ages four to six, when vaginal awareness also is present. In addition the material provides evidence that girls choose fathers to feel loved and valued, and that their wish for a baby is not a substitute for a relinquished wish for a penis. Observational studies and a vignette suggest that the instinctual drives of the genital phase coalesce with a change in object relations, forming an important motivation for a girl to switch her primary love object from her mother to her father.

  18. The effect of relationship status on communicating emotions through touch.

    2011-02-01

    Research into emotional communication to date has largely focused on facial and vocal expressions. In contrast, recent studies by Hertenstein, Keltner, App, Bulleit, and Jaskolka (2006) and Hertenstein, Holmes, McCullough, and Keltner (2009) exploring nonverbal communication of emotion discovered that people could identify anger, disgust, fear, gratitude, happiness, love, sadness and sympathy from the experience of being touched on either the arm or body by a stranger, without seeing the touch. The study showed that strangers were unable to communicate the self-focused emotions embarrassment, envy and pride, or the universal emotion surprise. Literature relating to touch indicates that the interpretation of a tactile experience is significantly influenced by the relationship between the touchers (Coan, Schaefer, & Davidson, 2006). The present study compared the ability of romantic couples and strangers to communicate emotions solely via touch. Results showed that both strangers and romantic couples were able to communicate universal and prosocial emotions, whereas only romantic couples were able to communicate the self-focused emotions envy and pride. © 2010 Psychology Press, an imprint of the Taylor & Francis Group, an Informa business

    Full Text Available La Orden Militar de San Juan envió grandes cantidades de dinero desde España hasta el Mediterráneo Oriental durante la Edad Media. No fueron grandes sumas durante los siglos XII y XIII. Sin embargo, aumentaron mucho en los siglos XIV y XV. Los hospitalarios aragoneses, catalanes y navarros fueron los que más dinero pagaban. En cambio, los hospitalarios castellanos y portugueses dieron menos. La Orden de San Juan envió no sólo dinero sino también caballos, trigo y armas. Los reyes españoles a veces no permitieron que los hospitalarios enviaran las transferencias desde la Península Ibérica al Oriente Latino. The Military Order of Saint John sent large amounts of money from Spain to the Eastern Mediterranean during the Middle Ages. They did not amount to large sums during the twelfth and thirteenth centuries. However, they increased greatly in the fourteenth and fifteenth centuries. The Aragonese, Catalonian and Navarrese Hospitallers were the ones that paid the most money. In contrast, the Castilian and Portuguese Hospitallers gave less. The Order of St. John sent not only money but also horses, wheat and arms.

    Analysis of associations between initial neurotic personality traits and subsequent reduction of suicidal ideation (SI) - or lack of such reduction - obtained until the end of hospitalization in patients who underwent the course of intensive psychotherapy conducted in integrative approach with predominance of psychodynamic approach. Symptom Checklist KO"O", Neurotic Personality Questionnaire KON-2006 and Life Inventory completed by 461 women and 219 men hospitalized in the day-hospital due to neurotic, behavioral and personality disorders between 2005-2013. At the stage of qualification 134 women and 80 men reported SI, of whom subsequently 84.3% and 77.5% respectively improved. Women with prominent Tendency to risk-taking (p=0.002) and Impulsiveness (p=0.038) constituted subgroups with decreased chances of improvement in terms of SI, while men with prominently elevated level of Envy (p=0.041) and women who seemed to have difficulties in expressing anger adequately (ppsychotherapy. Thus, those subgroups require special attention and diligent selection of therapeutic methods. Also, it is probable that focusing therapy at the above-mentioned personality components may increase effectiveness of SI treatment. Reducing SI during psychotherapy appears to be highly effective especially in women with difficulties in expressing anger adequately and in men with prominently elevated level of Envy, which suggests adequacy of this treatment choice and of targeting those difficulties during psychotherapy.

  2. Jupiter's Multi-level Clouds

    Science.gov (United States)

    1997-01-01

    Clouds and hazes at various altitudes within the dynamic Jovian atmosphere are revealed by multi-color imaging taken by the Near-Infrared Mapping Spectrometer (NIMS) onboard the Galileo spacecraft. These images were taken during the second orbit (G2) on September 5, 1996 from an early-morning vantage point 2.1 million kilometers (1.3 million miles) above Jupiter. They show the planet's appearance as viewed at various near-infrared wavelengths, with distinct differences due primarily to variations in the altitudes and opacities of the cloud systems. The top left and right images, taken at 1.61 microns and 2.73 microns respectively, show relatively clear views of the deep atmosphere, with clouds down to a level about three times the atmospheric pressure at the Earth's surface.By contrast, the middle image in top row, taken at 2.17 microns, shows only the highest altitude clouds and hazes. This wavelength is severely affected by the absorption of light by hydrogen gas, the main constituent of Jupiter's atmosphere. Therefore, only the Great Red Spot, the highest equatorial clouds, a small feature at mid-northern latitudes, and thin, high photochemical polar hazes can be seen. In the lower left image, at 3.01 microns, deeper clouds can be seen dimly against gaseous ammonia and methane absorption. In the lower middle image, at 4.99 microns, the light observed is the planet's own indigenous heat from the deep, warm atmosphere.The false color image (lower right) succinctly shows various cloud and haze levels seen in the Jovian atmosphere. This image indicates the temperature and altitude at which the light being observed is produced. Thermally-rich red areas denote high temperatures from photons in the deep atmosphere leaking through minimal cloud cover; green denotes cool temperatures of the tropospheric clouds; blue denotes cold of the upper troposphere and lower stratosphere. The polar regions appear purplish, because small-particle hazes allow leakage and reflectivity

    2010-01-01

    A generalization of the multi-symplectic form for Hamiltonian systems to self-adjoint systems with dissipation terms is studied. These systems can be expressed as multi-symplectic Birkhoffian equations, which leads to a natural definition of Birkhoffian multi-symplectic structure. The concept of Birkhoffian multi-symplectic integrators for Birkhoffian PDEs is investigated. The Birkhoffian multi-symplectic structure is constructed by the continuous variational principle, and the Birkhoffian multi-symplectic integrator by the discrete variational principle. As an example, two Birkhoffian multi-symplectic integrators for the equation describing a linear damped string are given.

    We study the formation of multi-armed spirals and multi-pairs antispirals in spatial rock–paper–scissors games with mobile individuals. We discover a set of seed distributions of species, which is able to produce multi-armed spirals and multi-pairs antispirals with a finite number of arms and pairs based on stochastic processes. The joint spiral waves are also predicted by a theoretical model based on partial differential equations associated with specific initial conditions. The spatial entropy of patterns is introduced to differentiate the multi-armed spirals and multi-pairs antispirals. For the given mobility, the spatial entropy of multi-armed spirals is higher than that of single armed spirals. The stability of the waves is explored with respect to individual mobility. Particularly, we find that both two armed spirals and one pair antispirals transform to the single armed spirals. Furthermore, multi-armed spirals and multi-pairs antispirals are relatively stable for intermediate mobility. The joint spirals with lower numbers of arms and pairs are relatively more stable than those with higher numbers of arms and pairs. In addition, comparing to large amount of previous work, we employ the no flux boundary conditions which enables quantitative studies of pattern formation and stability in the system of stochastic interactions in the absence of excitable media. -- Highlights: ► Multi-armed spirals and multi-pairs antispirals are observed. ► Patterns are predicted by computer simulations and partial differential equations. ► The spatial entropy of patterns is introduced. ► Patterns are relatively stable for intermediate mobility. ► The joint spirals with lower numbers of arms and pairs are relatively more stable.

    2014-01-01

    The use of multi-scale mathematical and computational models to study complex biological processes is becoming increasingly productive. Multi-scale models span a range of spatial and/or temporal scales and can encompass multi-compartment (e.g., multi-organ) models. Modeling advances are enabling virtual experiments to explore and answer questions that are problematic to address in the wet-lab. Wet-lab experimental technologies now allow scientists to observe, measure, record, and analyze experiments focusing on different system aspects at a variety of biological scales. We need the technical ability to mirror that same flexibility in virtual experiments using multi-scale models. Here we present a new approach, tuneable resolution, which can begin providing that flexibility. Tuneable resolution involves fine- or coarse-graining existing multi-scale models at the user's discretion, allowing adjustment of the level of resolution specific to a question, an experiment, or a scale of interest. Tuneable resolution expands options for revising and validating mechanistic multi-scale models, can extend the longevity of multi-scale models, and may increase computational efficiency. The tuneable resolution approach can be applied to many model types, including differential equation, agent-based, and hybrid models. We demonstrate our tuneable resolution ideas with examples relevant to infectious disease modeling, illustrating key principles at work. © 2014 The Authors.

    The multiplication of connected devices goes along with a large variety of applications and traffic types needing diverse requirements. Accompanying this connectivity evolution, the last years have seen considerable evolutions of wireless communication standards in the domain of mobile telephone networks, local/wide wireless area networks, and Digital Video Broadcasting (DVB). In this context, intensive research has been conducted to provide flexible turbo decoder targeting high throughput, multi-mode, multi-standard, and power consumption efficiency. However, flexible turbo decoder implementations have not often considered dynamic reconfiguration issues in this context that requires high speed configuration switching. Starting from this assessment, this paper proposes the first solution that allows frame-by-frame run-time configuration management of a multi-processor turbo decoder without compromising the decoding performances.

    Full Text Available In this paper, we present a new multi-level image thresholding technique, called Automatic Threshold based on Multi-objective Optimization "ATMO" that combines the flexibility of multi-objective fitness functions with the power of a Binary Particle Swarm Optimization algorithm "BPSO", for searching the "optimum" number of the thresholds and simultaneously the optimal thresholds of three criteria: the between-class variances criterion, the minimum error criterion and the entropy criterion. Some examples of test images are presented to compare our segmentation method, based on the multi-objective optimization approach with Otsu’s, Kapur’s and Kittler’s methods. Our experimental results show that the thresholding method based on multi-objective optimization is more efficient than the classical Otsu’s, Kapur’s and Kittler’s methods.

In all datasets, the ILH term increases the tracking accuracy of the multi-Bernoulli filter.

  4. Innovative multi rotor wind turbine designs

    Among the renewable energy sources, today wind energy is the most recognized and cost effective. Developers and researchers in this sector are optimistic and continuously working innovatively to improve the technology. The wind power obtained is proportional to the swept area of wind turbine. The swept area is increased by using a single rotor of large diameter or multi rotors in array. The rotor size is growing continuously with mature technology. Multi rotor technology has a long history and the multi rotor concept persists in a variety of modern innovative systems but the concept has fallen out of consideration in mainstream design from the perception that is complex and unnecessary as very large single rotor units are now technically feasible. This work addresses the evaluation of different multi rotor wind turbine systems. These innovative wind turbines are evaluated on the basis of feasibility, technological advantages, security of expected power performance, cost, reliability, impact of innovative system, comparison with existing wind turbine design. The findings of this work will provide guidelines for the practical and economical ways for further research on the multi rotor wind turbines. (Author)

    The Semantic web has given a great deal of impetus to the development of ontologies and multi-agent systems. Several books have appeared which discuss the development of ontologies or of multi-agent systems separately on their own. The growing interaction between agents and ontologies has highlighted the need for integrated development of these. This book is unique in being the first to provide an integrated treatment of the modeling, design and implementation of such combined ontology/multi-agent systems. It provides clear exposition of this integrated modeling and design methodology. It further illustrates this with two detailed case studies in (a) the biomedical area and (b) the software engineering area. The book is, therefore, of interest to researchers, graduate students and practitioners in the semantic web and web science area. (orig.)

    Marscher Alan P.

    2013-12-01

    Full Text Available The author reviews recent progress toward understanding blazars that multi-waveband monitoring observations have advanced. The primary techniques include the compilation of multi-waveband light curves, multi-epoch VLBI images at radio wavelengths, plots of linear polarization vs. time at radio through optical wavelengths, and spectral energy distributions (SEDs. Correlations and the coincidence or lag of events across wavebands and in the images indicate where the events take place relative to the “core” that lies ≳ 0.5 pc from the central engine. Rotations of the polarization electric vector suggest a helical geometry of the magnetic field upstream of the millimeter-wave core, while rapid fluctuations in degree and position angle of polarization imply that the jet plasma is turbulent in and downstream of the core. The author is developing a numerical model that simulates the emission from such turbulence as it interacts with a conical standing shock in the core region.

    In nuclear spectroscopy applications, it is often desired to acquire data at high rate with high resolution. With the availability of low cost computers, it is possible to make a powerful data acquisition system with minimum hardware and software development, by designing a PC plug-in acquisition board. But in using the PC processor for data acquisition, the PC can not be used as a multitasking node. Keeping this in view, PC plug-in acquisition boards with on-board processor find tremendous applications. Transputer based data acquisition board has been designed which can be configured as a high count rate pulse height MCA or as a Multi Spectral Scaler. Multi Spectral Scaling (MSS) is a new technique, in which multiple spectra are acquired in small time frames and are then analyzed. This paper describes the details of this multi spectral scaling data acquisition system. 2 figs

    Mangano, M.; Parke, S.; Xu Zhan

    1988-01-01

    For the six-gluon scattering process we give explicit and simple expressions for the amplitude and its square. To achieve this we use an analogy with string theories to identify a unique procedure for writing the multi-gluon scattering amplitudes in terms of a sum of gauge invariant dual sub-amplitudes multiplied by an appropriate color (Chan-Paton) factor. The sub-amplitudes defined in this way are invariant under cyclic permutations, satisfy powerful identities which relate different non-cyclic permutations and factorize in the soft gluon limit, the two-gluon collinear limit and on multi-gluon poles. Also, to leading order in the number of colors these sub-amplitudes sum incoherently in the square of the full matrix element. The results contained here are important for Monte Carlo studies of multi-jet processes at hadron colliders as well as for understanding the general structure of QCD. (orig.)

    2016-01-01

    Interactional aerodynamics of multi-rotor flows has been studied for a quadcopter representing a generic quad tilt-rotor aircraft in hover. The objective of the present study is to investigate the effects of the separation distances between rotors, and also fuselage and wings on the performance and efficiency of multirotor systems. Three-dimensional unsteady Navier-Stokes equations are solved using a spatially 5th order accurate scheme, dual-time stepping, and the Detached Eddy Simulation turbulence model. The results show that the separation distances as well as the wings have significant effects on the vertical forces of quadroror systems in hover. Understanding interactions in multi-rotor flows would help improve the design of next generation multi-rotor drones.

    2016-05-18

    The absorption efficiency of a coherent perfect absorber usually depends on the phase coherence of the incident waves on the surfaces. Here, we present a scheme to create a multi-channel coherent perfect absorber in which the constraint of phase coherence is loosened. The scheme has a multi-layer structure such that incident waves in different channels with different angular momenta can be simultaneously and perfectly absorbed. This absorber is robust in achieving high absorption efficiency even if the incident waves become "incoherent" and possess "random" wave fronts. Our work demonstrates a unique approach to designing highly efficient metamaterial absorbers. © CopyrightEPLA, 2016.

    We develop the path integral formalism for studying cosmological perturbations in multi-field inflation, which is particularly well suited to study quantum theories with gauge symmetries such as diffeomorphism invariance. We formulate the gauge fixing conditions based on the Poisson brackets of the constraints, from which we derive two convenient gauges that are appropriate for multi-field inflation. We then adopt the in-in formalism to derive the most general expression for the power spectrum of the curvature perturbation including the corrections from the interactions of the curvature mode with other light degrees of freedom. We also discuss the contributions of the interactions to the bispectrum.

  12. Multi-stage decoding for multi-level block modulation codes

    Science.gov (United States)

    1991-01-01

    In this paper, we investigate various types of multi-stage decoding for multi-level block modulation codes, in which the decoding of a component code at each stage can be either soft-decision or hard-decision, maximum likelihood or bounded-distance. Error performance of codes is analyzed for a memoryless additive channel based on various types of multi-stage decoding, and upper bounds on the probability of an incorrect decoding are derived. Based on our study and computation results, we find that, if component codes of a multi-level modulation code and types of decoding at various stages are chosen properly, high spectral efficiency and large coding gain can be achieved with reduced decoding complexity. In particular, we find that the difference in performance between the suboptimum multi-stage soft-decision maximum likelihood decoding of a modulation code and the single-stage optimum decoding of the overall code is very small: only a fraction of dB loss in SNR at the probability of an incorrect decoding for a block of 10(exp -6). Multi-stage decoding of multi-level modulation codes really offers a way to achieve the best of three worlds, bandwidth efficiency, coding gain, and decoding complexity.

    The transformation of Arctic sea ice from mainly perennial, multi-year ice to a seasonal, first-year ice is believed to have been accompanied by a reduction of the roughness of the ice cover surface. This smoothening effect has been shown to (i) modify the momentum and heat transfer between the atmosphere and ocean, (ii) to alter the ice thickness distribution which in turn controls the snow and melt pond repartition over the ice cover, and (iii) to bias airborne and satellite remote sensing measurements that depend on the scattering and reflective characteristics over the sea ice surface topography. We will review existing and novel remote sensing methodologies proposed to estimate sea ice roughness, ranging from airborne LIDAR measurement (ie Operation IceBridge), to backscatter coefficients from scatterometers (ASCAT, QUICKSCAT), to multi angle maging spectroradiometer (MISR), and to laser (Icesat) and radar altimeters (Envisat, Cryosat, Altika, Sentinel-3). We will show that by comparing and cross-calibrating these different products we can offer a consistent multi-mission, multi-decadal view of the declining sea ice roughness. Implications for sea ice physics, climate and remote sensing will also be discussed.

    Multi-strange bound hadron systems are excellent candidates for studying in-medium hyperon-hyperon (YY) interactions. A better understanding of the strangeness sector of the hadronic equation of state is crucial for our understanding of astrophysical objects like neutron stars. Furthermore, these studies are being motivated by actual and planed experimental activities on hypernuclear physics (HypHI and PANDA Collaborations). In fact, HypHI has already studied single-strange hypernuclei in heavy-ion collisions, whereas studies on double- and multi-strange nuclear systems are being planed by PANDA. We have reported in the past first studies on single- and double-Λ hypernuclei production in reactions induced by heavy-ions and antiprotons, respectively. The YY-interaction is still little known and many controversial theoretical predictions exist in the literature. We therefore extend our previous works by investigating the influence of various hyperon-hyperon interactions on the production dynamics of multi-Λ hypernuclei in reactions relevant for FAIR. Particular attention is paid to the heavy Ω-baryon (S=-3) and its role to the formation of multi-Λ hypernuclei in reactions induced by antiprotons.

    Multi-user facilities serve as a resource for many universities. In 2010, a survey was conducted investigating possible changes and successful characteristics of multi-user facilities, as well as identifying problems in facilities. Over 300 surveys were e-mailed to persons identified from university websites as being involved with multi-user facilities. Complete responses were received from 36 facilities with an average of 20 years of operation. Facilities were associated with specific departments (22%), colleges (22%), and university research centers (8.3%) or were not affiliated with any department or college within the university (47%). The five most important factors to succeed as a multi-user facility were: 1) maintaining an experienced, professional staff in an open atmosphere; 2) university-level support providing partial funding; 3) broad client base; 4) instrument training programs; and 5) an effective leader and engaged strategic advisory group. The most significant problems were: 1) inadequate university financial support and commitment; 2) problems recovering full service costs from university subsidies and user fees; 3) availability of funds to repair and upgrade equipment; 4) inability to retain highly qualified staff; and 5) unqualified users dirtying/damaging equipment. Further information related to these issues and to fee structure was solicited. Overall, there appeared to be a decline in university support for facilities and more emphasis on securing income by serving clients outside of the institution and by obtaining grants from entities outside of the university.
