An accurate numerical method for estimating the delay between two omni-directional receiving elements

In any two elements of a sensor array with omni-directional receiving elements, the effect of a narrow-band (NB) signal incident on the elements is the same for both of them, except for a phase lag or lead between them. In this paper a numerical algorithm for estimating the delay between the time series acquired by these two spatially separated elements is presented. The method makes use of a first-order all pass filter (APF) for creating a delay with respect to one of the two elements and compares it with the second element. An objective function is created which varies with the delay. This objective function is minimized using gold-section univariate minimization algorithm without gradients to yield an accurate estimate of delay. It is well known that there are limitations of using first-order APF for different sampling rates while minimizing the objective function. An innovative logic and methodology to overcome these issues is presented. This algorithm is applied to a 3-element Direction Finding (DF) system covering the entire azimuth plane. Results for various signal-to-noise (SNR) conditions are presented along with the intricacies of the algorithm. The DF system shows an accuracy, i.e. standard deviation (σ), of 1° or better for SNR less than 4 dB.
Moderate exponential time approximation and branching algorithms

We study links between approximation, exponential time computation and fixed parameter tractability. In particular, rather than focusing on one particular optimization problem, we tackle the question of finding sufficient conditions for a problem to admit "good" approximation algorithms in exponential time. In particular, we focus on the existence of "approximation schemata" (ratios 1 ± e for arbitrarily small e) and we exhibit conditions under which a technique of devising approximate branching algorithms reaches interesting results.
A decision support system for the monitoring of patients treated by hemodialysis based on a bayesian network

Telemedicine is a mean of facilitating the distribution of human resources and professional competences. It can speed up diagnosis and therapeutic care delivery and allow peripheral healthcare providers to receive continuous assistance from specialized centers. The need of specialized human resources becomes critical with the aging of the population. The treatment of renal failure is an example where telemedicine can help to increase care quality. Over the last decades Bayesian networks has become a popular representation for encoding uncertain expert knowledge. Dynamic Bayesian networks are an extension of Bayesian networks for modeling dynamic processes.We developed a dynamic Bayesian network adapted to the monitoring of the dry weight of patients suffering from chronic renal failure treated by hemodialysis. An experimentation conducted at dialysis units indicated that the system is reliable and gets the approbation of its users.
In vitro evaluation of 3D printed polycaprolactone scaffolds with angle-ply architecture for annulus fibrosus tissue engineering

Abstract Tissue engineering of the annulus fibrosus (AF) is currently being investigated as a treatment for intervertebral disc degeneration, a condition frequently associated with low back pain. The objective of this work was to use 3D printing to generate a novel scaffold for AF repair that mimics the structural and biomechanical properties of the native tissue. Multi-layer scaffolds were fabricated by depositing polycaprolactone struts in opposing angular orientations, replicating the angle-ply arrangement of the native AF tissue. Scaffolds were printed with varied strut diameter and spacing. The constructs were characterized morphologically and by static and dynamic mechanical analyses. Scaffold surfaces were etched with unidirectional grooves and the influence on bovine AF cell metabolic activity, alignment, morphology and protein expression was studied in vitro. Overall, the axial compressive and circumferential tensile properties of the scaffolds were found to be in a similar range to the native AF tissue. Confocal microscopy images indicated that cells were able to attach and spread on the smooth polycaprolactone scaffolds, but the surface texture induced cellular alignment and proliferation. Furthermore, immunofluorescence analysis demonstrated the aligned deposition of collagen type I, aggrecan and the AF-specific protein marker tenomodulin on the etched scaffolds. Overall, results demonstrated the potential for using the scaffolds as a template for AF regeneration.
Self-Excitation: An Enabler for Online Thermal Estimation and Model Predictive Control of Buildings

This paper investigates a method to improve buildings' thermal predictive control performance via online identification and excitation (active learning process) that minimally disrupts normal operations. In previous studies we have demonstrated scalable methods to acquire multi-zone thermal models of passive buildings using a gray-box approach that leverages building topology and measurement data. Here we extend the method to multi-zone actively controlled buildings and examine how to improve the thermal model estimation by using the controller to excite unknown portions of the building's dynamics. Comparing against a baseline thermostat controller, we demonstrate the utility of both the initially acquired and improved thermal models within a Model Predictive Control (MPC) framework, which anticipates weather uncertainty and time-varying temperature set-points. A simulation study demonstrates self-excitation improves model estimation, which corresponds to improved MPC energy savings and occupant comfort. By coupling building topology, estimation, and control routines into a single online framework, we have demonstrated the potential for low-cost scalable methods to actively learn and control buildings to ensure occupant comfort and minimize energy usage, all while using the existing building's HVAC sensors and hardware.
Low Power VLSI Design of Modified Booth Multiplier

Low power VLSI circuits became very vital criteria for designing the energy efficient electronic designs for prime performance and compact devices. Multipliers play a very important role for planning energy economical processors that decides the potency of the processor. To scale back the facility consumption of multiplier factor booth coding methodology is being employed to rearrange the input bits. The operation of the booth decoder is to rearrange the given booth equivalent. Booth decoder can increase the range of zeros in variety. Hence the switching activity are going to be reduced that further reduces the power consumption of the design. The input bit constant determines the switching activity part that's once the input constant is zero corresponding rows or column of the adder ought to be deactivated. When multiplicand contains a lot of number of zeros the higher power reduction will takes place. therefore in booth multiplier factor high power reductions are going to be achieved.
Cortical Substrates of Perceptual Stability during Eye Movements

We are usually unaware of retinal image motion resulting from our own movement. For instance, during slow-tracking eye movements, the world around us remains perceptually stable despite the retinal image slip induced by the eye movement. This example of perceptual invariance is achieved by subtracting an internal reference signal, reflecting the eye movement, from the retinal motion signal. If the two cancel each other, visual structures, which do not move, will also be perceived as nonmoving. If, however, the reference signal is too small or too large, a false eye-movement-induced motion of the external world will be perceived. We have exploited our ability to manipulate the size of the reference signal in an attempt to reveal the structures in visual cortex, encoding the perception of self-induced visual motion rather than the retinal motion signal. Using EEG and lately also MEG recordings in human subjects and single-unit recordings in monkeys, we have been able to show that our ability to perceive the world as stationary despite eye-movement-induced retinal image slip is based on "late" parts of the cortical hierarchy of motion processing, sparing the early stages up to cortical area MT and, among others, involving cortex at the junction between the parietal and temporal lobes close to the parieto-insular-vestibular cortex. Lesions of this network in humans render the visual system unable to compensate for the visual consequences of eye movements, giving rise to severe dizziness, whenever the eyes move smoothly.
Leptin: a potential regulator of polymorphonuclear neutrophil bactericidal action?

It is well known that leptin, the ob gene product, is involved in the regulation of food intake and thermogenesis. Recent studies also demonstrate that leptin may be able to modulate functions of cells involved in nonspecific immune response such as phagocytosis and secretion of cytokines by macrophages. This and the prominent implication of polymorphonuclear neutrophils (PMNs) in infectious response suggested a possible role of leptin as a modulator of PMN functions. We detected a leptin receptor on the PMN membrane by immunocytochemistry with an anti‐leptin receptor. Using chemiluminescence we then demonstrated that leptin enhances oxidative species production by stimulated PMNs. These results show for the first time that a functional leptin receptor is present on PMNs and that leptin may be able to influence their oxidative capacity.
Explicit Formulas for Relaxed Disarrangement Densities Arising from Structured Deformations

Structured deformations provide a multiscale geometry that captures the contributions at the macrolevel of both smooth geometrical changes and non-smooth geometrical changes (disarrangements) at submacroscopic levels. For each (first-order) structured deformation $(g,G)$ of a continuous body, the tensor field $G$ is known to be a measure of deformations without disarrangements, and $M:=\nabla g-G$ is known to be a measure of deformations due to disarrangements. The tensor fields $G$ and $M$ together deliver not only standard notions of plastic deformation, but $M$ and its curl deliver the Burgers vector field associated with closed curves in the body and the dislocation density field used in describing geometrical changes in bodies with defects. Recently, Owen and Paroni [13] evaluated explicitly some relaxed energy densities arising in Choksi and Fonseca's energetics of structured deformations [4] and thereby showed: (1) $(trM)^{+}$, the positive part of $trM$, is a volume density of disarrangements due to submacroscopic separations, (2) $(trM)^{-}$, the negative part of $trM$, is a volume density of disarrangements due to submacroscopic switches and interpenetrations, and (3) $|trM|$, the absolute value of $trM$, is a volume density of all three of these non-tangential disarrangements: separations, switches, and interpenetrations. The main contribution of the present research is to show that a different approach to the energetics of structured deformations, that due to Ba\'ia, Matias, and Santos [1], confirms the roles of $(trM)^{+}$, $(trM)^{-}$, and $|trM|$ established by Owen and Paroni. In doing so, we give an alternative, shorter proof of Owen and Paroni's results, and we establish additional explicit formulas for other measures of disarrangements.
Stability and stabilization of stochastic linear parameter varying T-S fuzzy system

This paper studies the stability and stabilization of stochastic Linear Parameter Varying (LPV) Takagi-Sugeno (T-S) fuzzy system. Concretely, the affine T-S fuzzy linearization approach is used to deal with the nonlinearity of the parameter-dependent stochastic nonlinear system and the stochastic LPV T-S fuzzy system is obtained. While bringing in the parameter-dependent Piecewise Quadratic Lyapunov Functions (PQLFs) and considering the approximation error, the stability problem and stabilization problem of the stochastic LPV T-S fuzzy system are discussed and the sufficient conditions are deduced in Linear Matrix Inequalities (LMIs) form.
Validation of the Korean version of social achievement goals for adolescents: paths from social achievement goals through social behaviour to social adjustment

ABSTRACT The purpose of this study is to translate and validate the Korean version of the social achievement goals scale, which is known to be a significant variable in predicting social behaviour and social adjustments. There were 133 seventh grade middle school students (male = 64, female = 69) who took part in Study 1, and 425 seventh to eighth grade middle school students (male = 293, female = 132) who participated in Study 2. Explanatory factor analysis of Study 1 revealed that the Korean version of the social achievement goals scale consists of three factors (i.e., social development, demonstration approach, and demonstration avoid goals) with six items for each. Confirmatory factor analysis of Study 2 confirmed the three-factor structure. Latent mean analysis revealed that girls endorsed a higher level of the social development goal, while boys endorsed a higher level of the social demonstration approach goal than girls. No difference was found for the social demonstration avoid goal. The test of criterion-related validity revealed that the social development goal indirectly predicted perceived popularity through prosocial behaviour. The social demonstration approach goal positively predicted aggressive behaviour and perceived popularity, while the social demonstration avoid goal negatively predicted both of them. Taken together, we found that the social achievement goals framework is also applicable to Korean adolescents in the same way as Western samples.
Vancomycin-resistant Staphylococcus aureus (VRSA) from Nepal: a cocktail story.

The merit of a scientific writing is high only when it disseminates the new knowledge in a universally accepted and logical manner. I, with great interest, have read a paper entitled “Bacteriology and antimicrobial susceptibility of adult chronic dacryocystitis” by Chaudhary et al (2010). This paper of writing has raised few concerns after reading it and compelled me to bring the issues to the notice of the scientific community. The first issue concerns with the inappropriate way of citation and referencing observed in the paper. Accuracy of citation and referencing has been a questionable issue in Nepal (Adhikari, 2009). The authors (Chaudhary et al, 2010) have wrongly cited our paper (Dumre et al, 2008) in the discussion section for a misleading information regarding the vancomycin resistant Staphylococcus aureus (VRSA). The authors cited our work giving an impression that all the isolates we reported in our study were VRSA which information is totally wrong because we had reported only 5% as methillin resistant S. aureus (MRSA) and none of them were VRSA which is also clearly written in our abstract (Dumre et al, 2008). Moreover, the way of citation in the text is also wrong as they cited our paper as “Malla et al, 2008” which should be “Dumre et al, 2008”. The list of references contains inaccurate order of authors. This brings about a doubt whether the authors really read the cited paper.
Radiation from the first forming stars

The evolution of radiation emitted during the dynamical collapse of metal-free protostellar clouds is investigated within a spherically symmetric hydrodynamical scheme that includes the transfer of radiation and the chemistry of the primordial gas. The cloud centre collapses on a time-scale of ∼105–6 yr, thanks to line cooling from molecular hydrogen (H2). For most of the collapse time, when the evolution proceeds self-similarly, the luminosity slowly rises up to ∼1036 erg and is essentially a result of H2 infrared (IR) line emission. Later, continuum IR radiation provides an additional contribution, which is mostly a result of the accretion of an infalling envelope upon a small hydrostatic protostellar core that develops in the centre. We follow the beginning of the accretion phase, when the enormous accretion rate (∼0.1 M⊙ yr−1) produces a very high continuum luminosity of ∼1036 erg. Despite the high luminosities, the radiation field is unable to affect the gas dynamics during the collapse and the first phases of accretion, because the opacity of the infalling gas is too small; this is quite different from present-day star formation. We also find that the protostellar evolution is similar among clouds with different initial configurations, including those resulting from three-dimensional cosmological simulations of primordial objects; in particular, the shape of the molecular spectra is quite universal. Finally, we briefly discuss the detectability of this initial cosmic star formation activity.
Family factors associated with anxiety sensitivity in youth

Family Factors Associated with Anxiety Sensitivity in Youth By Kelly Lynn Drake Dr. Christopher A. Kearney, Examination Committee Chair Associate Professor o f Psychology University o f Nevada, Las Vegas The purpose o f this study was to examine the relationship between various family variables and anxiety sensitivity (AS) in a community sample of 159 youth ages 7-18 years and their parents. Youth completed self-report measures of anxiety and AS and parents completed measures of AS, attachment, psychopathology, family environment, and parenting practices. The primary purpose was to examine the extent to which these family variables predicted child AS. Results indicated that a combination of family factors including parenting style, parental psychopathology, and family environment significantly predicted child AS. Specifically, parent's perceptions of their child's anxiety sensitivity and a secure attachment contributed the most to the prediction equation. These results are discussed in the context o f their implications for both assessment and treatment of youth with AS.
Ultrasonography of the lower extremity veins: anatomy and basic approach

Ultrasonography is an imaging modality widely used to evaluate venous diseases of the lower extremities. It is important to understand the normal venous anatomy of the lower extremities, which has deep, superficial, and perforating venous components, in order to determine the pathophysiology of venous disease. This review provides a basic description of the anatomy of the lower extremity veins and useful techniques for approaching each vein via ultrasonography.

Veriication of Meta-interpreters

A novel approach to the veriication of meta-interpreters is introduced. We apply a general purpose veriication method for logic programs, proposed in 28], to the case study of the Vanilla and other logic meta-interpreters. We extend the standard notion of declarative correctness, and design a criterion for proving correctness of meta-interpreters in a general sense, including amalgamated and reeective meta-interpreters. The contribution of this paper can be summarized as follows: under certain natural assumptions, all interesting veriication properties lift up from the object program to the meta-program, including partial correctness, termination, absence of errors, call patterns persistence, correct instances of queries, computed instances of queries. Interestingly, it is possible to establish these results on the basis of purely declarative reasoning, using the mentioned proof method. We believe that the obtained results illustrate the broad applicability of the adopted veriication principles.
An Analysis of Key Factors for the Success of the Communal Management of Knowledge

This paper explores the links between Knowledge Management and new community-based models of the organization from both a theoretical and an empirical perspective. From a theoretical standpoint, we look at Communities of Practice (CoPs) and Knowledge Management (KM) and explore the links between the two as they relate to the use of information systems to manage knowledge. We begin by reviewing technologically supported approaches to KM and introduce the idea of Systemes d'Aide a la Gestion des Connaissances SAGC (Systems to aid the Management of Knowledge). Following this we examine the contribution that communal structures such as CoPs can make to intraorganizational KM and highlight some of 'success factors' for this approach to KM that are found in the literature. From an empirical standpoint, we present the results of a survey involving the Chief Knowledge Officers (CKOs) of twelve large French businesses; the objective of this study was to identify the factors that might influence the success of such approaches. The survey was analysed using thematic content analysis and the results are presented here with some short illustrative quotes from the CKOs. Finally, the paper concludes with some brief reflections on what can be learnt from looking at this problem from these two perspectives.
Application of signature strengths at work: A dual-level analysis

ABSTRACT Each individual possesses character strengths, the most significant of which are classified as signature strengths. With a sample of 164 individuals who were employed at least part-time in a variety of industries, we examined application of signature strengths and well-being both between-persons (global) and within-persons (daily). Global application of signature strengths was associated with global job satisfaction and strain; however, no significant mediation effects on intent to turnover were found. We also found that daily variations in application of signature strengths were related to daily job satisfaction and strain. Common method bias associated with trait positive and negative affect differed by level of analysis: At the between-person (global) level, trait affect produced substantial inflation of estimates, but at the within-person (daily) level, inflation was negligible. The results suggest the importance of daily opportunities to apply signature strengths and of accounting for variance attributable to trait affect in between-person analyses.
