Fault tolerant control of a quadrotor based on parameter estimation techniques and use of a reconfigurable PID controller

This paper focuses on the fault tolerant control for a quadrotor. In this paper, both a complete dynamic model of quadrotor and a simple reconfigurable PID controller are presented. Besides, FDD and FTC techniques are developed using parameter estimation techniques. The proposed approach allows to detect and to diagnose faults in a rotor. The main contribution of this article relies on the detailed modelling of a quadrotor and a use of parameter estimation techniques including an expert method based on the knowledge of the system and a logical reasoning.
Cultural Practices and Nutritional Status Among Premenopausal Women of Urban Setup in India

A data of 124 adult women who had not attained menopause, age ranging from 21-50 years was collected to see the impact of nutritional status as assessed by Body mass index which were categorized according to World Health Organization and cultural practices. Majority of adult urban women were in overweight category followed by normal category and obese category and very few remained in the underweight category. With the increase in number of children, there was a shift in BMI category from normal to obese with substantial prevalence of women noticed in overweight cate- gory. Maximum numbers of women were found in overweight category with two children. Normal weight category is also well represented with number of pregnancies. No woman with three children was reported in underweight category. It is evident that there is shift towards obese category with the number of children, confirming to the cultural practice of giving rich diets to mothers during and after delivery.
On the Modeling and Verification of a Telecom System Block Using MDGs

In this report, we investigate the ability of MDGs (Multiway Decision Graphs) to carry out a verification process of a large industrial Telecom hardware which is commercialized by PMC-Sierra Inc. Until recently, the Cambridge Fairisle ATM switch fabric with 4200 equivalent gates was the largest industrial like design verified with the MDG tools. The design we consider in this study is a Telecom System Block (TSB), called RASE, containing 11400 equivalent gates. For the formal verification, we adopted a hierarchical proof methodology to handle the complexity of the design. We then carried out MDG based equivalence checking as well as model checking. To measure the performance of the MDG verification, we also conducted the verification of the same TSB with Cadence FormalCheck. The experimental results showed that in some cases, the MDG model checker was more efficient due to the ability with MDGs to use abstract state variables and uninterpreted function symbols rather than simply a Boolean modeling as in FormalCheck.
Tracking requirements evolution by using issue tickets: a case study of a document management and approval system

Requirements evolve throughout the software life-cycle. When requirements change, requirements engineers must determine what software artifacts could be affected. The history of and rationale for requirements evolution provides engineers some information about artifact dependencies for impact analysis. In this paper, we discuss a case study of requirements evolution for a large-scale system governed by Japanese laws and regulations. We track requirements evolution using issue tickets created in response to stakeholder requests. We provide rules to identify requirements evolution events (e.g. refine, decompose, and replace) from combinations of operations (e.g. add, change, and delete) specified in the issue tickets. We propose a Requirements Evolution Chart (REC) to visually represent requirements evolution as a series of events over time, and implement tool support to generate a REC from a series of issue tickets using our rules to identify requirements evolution events. We found that the REC supports impact analysis and compliance efforts.

s International 1981;41(12-B, Pt 1):46804681. Luepnitz DA. Maternal, paternal and joint custody: A study of families after divorce. Dissertation Abstracts International 1980;41(6-B):2332. 43 families with either maternal, paternal, or joint custody were interviewed an average of 3.5 yrs after divorce. Most of the 91 children in the sample were not maladjusted, and their adjustment was independent of custody type. Where parents remained embattled after divorce, children had significantly lower scores on the Piers-Harris Children's Self-Concept Scale and on parents' ratings of their adjustment. Children in joint custody retained filial relationships with both parents, as opposed to the avuncular relationships children developed with noncustodial parents in the single custody situation. It is concluded that joint custody at its best is superior to single-parent custody at its best. However, the author cautions against a legal presumption for the joint award and discusses some contraindications to its use.
Barriers and facilitating factors to help‐seeking for symptoms of clinical anxiety in adolescent males

Abstract Objective Young men are very reluctant to seek help for anxiety disorders. In particular, the factors that facilitate mental health help‐seeking in adolescent males are poorly understood. This study aimed to investigate the barriers and facilitating factors to help‐seeking behaviour for clinical anxiety in Australian adolescent males. Method The views of 29 adolescent males, both with and without experience of clinical anxiety symptoms, were elicited using semi‐structured interviews and focus groups. Verbatim transcripts were analysed using grounded theory. Results Primary barriers to help‐seeking included stigma (particularly in relation to social norms of masculinity), effort, limited awareness/knowledge of symptoms of anxiety and a sense of being ‘confronted’ by private emotions through help‐seeking. Facilitating factors included increasing the accessibility of school‐based mental health literacy programs and providing a wider range of formal and informal help‐seeking options. Other facilitators related to amendments in how mental health information is presented and investments into high speed/low effort help‐seeking options. A preliminary model of mental health help‐seeking in adolescent males with clinical anxiety is presented. Conclusion Adolescent males feel that they risk significant stigma by help‐seeking for mental health problems but lack information as to the benefits or the experience of help seeking. A stepped approach to options for mental health support and information for this population should be evaluated.
On Optimality of Jury Selection in Crowdsourcing

Recent advances in crowdsourcing technologies enable computationally challenging tasks (e.g., sentiment analysis and entity resolution) to be performed by Internet workers, driven mainly by monetary incentives. A fundamental question is: how should workers be selected, so that the tasks in hand can be accomplished successfully and economically? In this paper, we study the Jury Selection Problem (JSP): Given a monetary budget, and a set of decision-making tasks (e.g., “Is Bill Gates still the CEO of Microsoft now? ”), return the set of workers (called jury), such that their answers yield the highest “Jury Quality” (or JQ). Existing JSP solutions make use of the Majority Voting (MV) strategy, which uses the answer chosen by the largest number of workers. We show that MV does not yield the best solution for JSP. We further prove that among all voting strategies (including deterministic and randomizedstrategies), BayesianVoting(BV)canoptimallysolveJSP. We then examine how to solve JSP based on BV. This is technically challenging, since computing the JQ with BV is NP-hard. We solve this problem by proposing an approximate algorithm that is computationally efficient. Our approximate JQ computation algorithm is also highly accurate, and its error is proved to be bounded within 1%. We extend our solution by considering the task owner’s “belief” (or prior) on the answers of the tasks. Experiments on synthetic and real datasets show that our new approach is consistently better than the best JSP solution known.
Feed-Forward Microprocessing and Splicing Activities at a MicroRNA–Containing Intron

The majority of mammalian microRNA (miRNA) genes reside within introns of protein-encoding and non-coding genes, yet the mechanisms coordinating primary transcript processing into both mature miRNA and spliced mRNA are poorly understood. Analysis of melanoma invasion suppressor miR-211 expressed from intron 6 of melastatin revealed that microprocessing of miR-211 promotes splicing of the exon 6–exon 7 junction of melastatin by a mechanism requiring the RNase III activity of Drosha. Additionally, mutations in the 5′ splice site (5′SS), but not in the 3′SS, branch point, or polypyrimidine tract of intron 6 reduced miR-211 biogenesis and Drosha recruitment to intron 6, indicating that 5′SS recognition by the spliceosome promotes microprocessing of miR-211. Globally, knockdown of U1 splicing factors reduced intronic miRNA expression. Our data demonstrate novel mutually-cooperative microprocessing and splicing activities at an intronic miRNA locus and suggest that the initiation of spliceosome assembly may promote microprocessing of intronic miRNAs.
LOVE AND ATTACHMENT

It is not uncommon for philosophers to name disinterestedness, or some like feature, as an essential characteristic of love. Such theorists claim that in genuine love, one’s concern for her beloved must be noninstrumental, non-egocentric, or even selfless. These views prompt the question, "what, if any, positive role might self-interestedness play in genuine love? " In this paper, I argue that attachment, an attitude marked primarily by self-focused emotions and emotional predispositions, helps constitute the meaning and import of at least some kinds of adult reciprocal love. In this way, attachment represents a type of self-interestedness that not only contributes positively to such relationships but is also essential to them.
Integration of hormonal signaling networks and mobile microRNAs is required for vascular patterning in Arabidopsis roots

Significance The vascular tissues form a continuous network providing the long-distance transport of water and nutrients in all higher plants (tracheophytes). To incorporate separate organs into this network, it is essential that the position of different vascular cell types is tightly regulated. Several factors required for root vascular patterning (including hormones and gene products) have previously been identified in the model plant Arabidopsis. We have now established a mathematical model formulizing the interaction between these factors, allowing us to identify a minimal regulatory network capable of maintaining a stable vascular pattern in Arabidopsis roots. We envisage that this model will help future researchers understand how similar regulatory units can be applied to create alternative patterns in other species. As multicellular organisms grow, positional information is continually needed to regulate the pattern in which cells are arranged. In the Arabidopsis root, most cell types are organized in a radially symmetric pattern; however, a symmetry-breaking event generates bisymmetric auxin and cytokinin signaling domains in the stele. Bidirectional cross-talk between the stele and the surrounding tissues involving a mobile transcription factor, SHORT ROOT (SHR), and mobile microRNA species also determines vascular pattern, but it is currently unclear how these signals integrate. We use a multicellular model to determine a minimal set of components necessary for maintaining a stable vascular pattern. Simulations perturbing the signaling network show that, in addition to the mutually inhibitory interaction between auxin and cytokinin, signaling through SHR, microRNA165/6, and PHABULOSA is required to maintain a stable bisymmetric pattern. We have verified this prediction by observing loss of bisymmetry in shr mutants. The model reveals the importance of several features of the network, namely the mutual degradation of microRNA165/6 and PHABULOSA and the existence of an additional negative regulator of cytokinin signaling. These components form a plausible mechanism capable of patterning vascular tissues in the absence of positional inputs provided by the transport of hormones from the shoot.
Asignación de niveles de aprendizaje a las colocaciones del Diccionario de Colocaciones del español

This article puts forward a method to level the collocations of the Diccionario de Colocaciones del Espanol according to the levels proposed in the MCER. The frequency that the collocations contained in the dictionary exhibit in the corpus has been used as the levelling criteria. By means of the analysis of a sample of collocations included in both the dictionary and the Plan Curricular del Instituto Cervantes, it is proven a negative correlation between the levelling proposed for those collocations in the Plan Curricular and the corpus frequency. Such correlation justifies the relevance of the frequency as a levelling criterion. Finally, a qualitative exam of the results is carried out to prove the validity of the proposed method.
DRESSAGE AND THE ILLUSION OF ENTERPRISE CONTROL *

A recent stream of information systems research emphasises the institutional or structural forces that can be embodied in an enterprise system. Other research focuses on the locally idiosyncratic adoption patterns of users after an enterprise systems implementation. To understand the tension that arises when these opposing views meet, we draw on Foucault’s notion of dressage. Dressage implies the exercise of total control by a governing body over the activities of its inhabitant population. In a context of enterprise systems, dressage is reflected in the control-rooted standardised rationality which is inherent in such systems, as well as in the ostensive compliance of individuals to such systems. Dressage highlights that enterprise systems may contain elements of non-productive control, and that responses to such control may appear to be compliant, whereas non-standardised locally idiosyncratic activities persist outside of the system’s gaze. These “organic” activities may be vital for organisational flexibility and for ongoing effective organisational performance.
Ultraviolet Signposts of Resonant Dynamics in the Starburst-ringed Sab Galaxy M94 (NGC 4736)

The dynamic orchestration of star-birth activity in the starburst-ringed galaxy M94 (NGC 4736) is investigated using images from the Ultraviolet Imaging Telescope (UIT; far-ultraviolet [FUV] band), Hubble Space Telescope (HST; near-ultraviolet [NUV] band), Kitt Peak 0.9 m telescope (Hα, R, and I bands), and Palomar 5 m telescope (B band), along with spectra from the International Ultraviolet Explorer (IUE) and the Lick 1 m telescope. The wide-field UIT image shows FUV emission from (1) an elongated nucleus, (2) a diffuse inner disk, where Hα is observed in absorption, (3) a bright inner ring of H II regions at the perimeter of the inner disk (R = 48″ = 1.1 kpc), and (4) two 500 pc size knots of hot stars exterior to the ring on diametrically opposite sides of the nucleus (R = 130″ = 2.9 kpc). The HST Faint Object Camera image resolves the NUV emission from the nuclear region into a bright core and a faint 20″ long "minibar" at a position angle of 30°. Optical and IUE spectroscopy of the nucleus and diffuse inner disk indicates a ∼107–108 yr old stellar population from low-level star-birth activity blended with some LINER activity. Analysis of the Hα-, FUV-, NUV-, B-, R-, and I-band emissions, along with other observed tracers of stars and gas in M94, indicates that most of the star formation is being orchestrated via ring-bar dynamics, involving the nuclear minibar, inner ring, oval disk, and outer ring. The inner starburst ring and bisymmetric knots at intermediate radius, in particular, argue for bar-mediated resonances as the primary drivers of evolution in M94 at the present epoch. Similar processes may be governing the evolution of the "core-dominated" galaxies that have been observed at high redshift. The gravitationally lensed "Pretzel Galaxy" (0024+1654) at a redshift of ∼1.5 provides an important precedent in this regard.
3D segmentation of forest structure using a mean-shift based algorithm

Consistent and accurate information on 3D forest canopy structure is required by many applications like forest inventory, management, logging, fuel mapping, habitat studies or biomass estimate. Compared to other remote sensing techniques (e.g., SAR or photogrammetry), airborne laser scanning is an adapted tool to provide such information by generating a three-dimensional georeferenced point cloud. Vertical structure analysis consists in detecting the number of layers within a forest stand and their limits. Until now, there is no approach that properly segments the different strata of a forest. In this study, we directly work on the 3D point cloud and we propose a mean shift (MS) based procedure for vertical forest segmentation. The approach that is carried out on complex forest plots improves the discrimination of vegetation strata.

Residual neurocognitive features of long-term ecstasy users with minimal exposure to other drugs.

AIMS In field studies assessing cognitive function in illicit ecstasy users, there are several frequent confounding factors that might plausibly bias the findings toward an overestimate of ecstasy-induced neurocognitive toxicity. We designed an investigation seeking to minimize these possible sources of bias. DESIGN We compared illicit ecstasy users and non-users while (1) excluding individuals with significant life-time exposure to other illicit drugs or alcohol; (2) requiring that all participants be members of the 'rave' subculture; and (3) testing all participants with breath, urine and hair samples at the time of evaluation to exclude possible surreptitious substance use. We compared groups with adjustment for age, gender, race/ethnicity, family-of-origin variables and childhood history of conduct disorder and attention deficit hyperactivity disorder. We provide significance levels without correction for multiple comparisons. SETTING Field study. PARTICIPANTS Fifty-two illicit ecstasy users and 59 non-users, aged 18-45 years. MEASUREMENTS Battery of 15 neuropsychological tests tapping a range of cognitive functions. FINDINGS We found little evidence of decreased cognitive performance in ecstasy users, save for poorer strategic self-regulation, possibly reflecting increased impulsivity. However, this finding might have reflected a pre-morbid attribute of ecstasy users, rather than a residual neurotoxic effect of the drug. CONCLUSIONS In a study designed to minimize limitations found in many prior investigations, we failed to demonstrate marked residual cognitive effects in ecstasy users. This finding contrasts with many previous findings-including our own-and emphasizes the need for continued caution in interpreting field studies of cognitive function in illicit ecstasy users.

Virtual reality technology has the realistic significance in the applied research of the garment field. In this paper, we present the central application fields for cloth simulation. Furthermore, describe the method for design and implementation the 3D Qipao Display System. This System can fully demonstrate the characteristics of patterns of the classic Qipao. In contrast with the traditional display approaches, the virtual garment display system based on virtual reality technology shows the better intuitional and interactive visual effect.
Basic Assumptions and Definitions in The Analysis of Financial Leverage

The financial leverage literature has been in a state of terminological chaos for decades as evidenced, for example, by the Nobel Prize Lecture mistake on the one hand, and the global financial crisis on the other. A meaningful analysis of the leverage phenomenon calls for the formulation of a coherent set of assumptions and basic definitions. The objective of the paper is to answer this call. The paper defines leverage as a value neutral concept useful in explaining the magnification effect exerted by financial activity upon the whole spectrum of financial results. By adopting constructivism as a methodological approach, we are able to introduce various types of leverage such as capital and income, base and non-base, accounting and market value, for levels and for distances (absolute and relative), costs and simple etc. The new definitions formulated here are subsequently adopted in the analysis of the content of leverage statements used by the leading finance textbook.
Gender and bargaining: Experimental evidence from rural Uganda

We study gender differences in bilateral bargaining using an artefactual field experiment in rural Uganda, through variation in gender composition of bargaining pairs and in disclosure of identities. Disagreement is common independently of disclosure condition, but less frequent among female-only pairs. When paired with a man who is informed about their identity, women tend to demand less than men in the same situation. The influence of beliefs on demands is stronger for men than for women, and this difference is larger under anonymity than when identities are disclosed. These results identify important mechanisms that induce gender inequality in resource access.
Assimilation of satellite observations of long-lived chemical species in global chemistry transport models

Use of data assimilation techniques such as optimal interpolation or the Kaiman filter in global chemistry transport models (CTM) is becoming more common. However, owing to high computational requirements, it is often difficult to apply these techniques to multidimensional models containing extensive photochemical schemes. We present a sequential assimilation approach developed for use with general global chemistry transport models. It allows fast assimilation and mapping of satellite observations and provides estimates of analysis errors. The suggested data assimilation scheme evolved from the one described by Levelt et al. [1998]. It is a variant of the suboptimal Kaiman filter and is based on ideas described by Menard et al. [2000] and Menard and Chang [200O]. One of the most important features of the developed scheme is its ability to routinely estimate variance of the analysis and to predict variance evolution in the model. The developed technique (or its variants) has been successfully interfaced with a number of different global models and used for assimilation of several types of measurements, including aerosol extinction ratios. Some of these experiments are described by Lamarque et al. [1999] and W. D. Collins et al. (Forecasting aerosols using a chemical transport model with assimilation of satellite aerosol retrievals: Methodology for INDOEX, submitted to Journal of Geophysical Research, 2000, hereinafter referred to as Collins et al., submitted manuscript, 2000). We illustrate the method using assimilation of ozone observations made by the Upper Atmosphere Research Satellite/Microwave Limb Sounder in the three-dimensional chemistry transport model ROSE [Research for Ozone in the Stratosphere and its Evolution; Rose and Brasseur, 1989].
