Stereo-PIV Measurement of Turbulence Shear Stress in a Stirred Flow Mixer

The turbulence dissipation rate and turbulence shear stress are estimated inside a cylindrical, stirred flow mixer by carrying out Stereo PIV measurements in twelve vertical and three horizontal planes. The flow domain is vertically oriented, filled with the water. A commercially-available, three-blade impeller, HR-100, is used as the agitator. The impeller is mounted near the tip of a thin, rigid shaft, which is aligned along the central axis of the flow domain. The impeller rotates with the constant angular speed of 150RPM, and the Reynolds number based on the impeller diameter and the blade's tip-velocity is equal to 59400. The turbulence statistics in the vertical measurement planes are reported before (Shekhar C, Nishino K, Yamane Y and Huang J, Stereo-PIV measurement of turbulence characteristics in a flow mixer Journal of Visualization 15 (2012) pp.293~308), which revealed that the rotation induces a downward, as well as tangential, bulk flow motion, which convects the turbulence generated at the blade-water interface, causing the turbulence level below the impeller to be much higher than the level above it. The present study is the second part of the same project, and reports the turbulence statistics in the horizontal measurement planes. The results show that the turbulence level is high in the area swept by the rotating impeller blades and underneath. However, in the outside region, the turbulence damps down and becomes negligible. The vertical and horizontal measurement results are also combined to estimate the production, convection, viscous diffusion, and turbulence dissipation terms of the turbulence kinetic energy's budget equation, along with the turbulence shear stress, along the lines where the different vertical and horizontal planes intersect.
Approximation of Image Shape by Half-Elliptical Arc Segments & Representation by Speech Sound Pattern for Visually Impaired Person

This paper describes a new approach by which a blind person can visualize the approximate shape of the image by hearing sound. Nowadays a lot of image shape approximation and representation algorithms are available, but these algorithms represent image contour as a sequence of straight line segments. This work proposed a digital image shape approximation method where a shape boundary is divided & approximated to a few numbers of half-elliptical arc segments. These half elliptical arc segments are then represented by three-phoneme speech sound pattern so that on hearing this sound a blind person can get information about the shape of an object.
Ju n 20 05 Generalizations of Quantum Mechanics

We review realistic models that reproduce quantum theory in some limit and yield potentially new physics outside that limit. In particular, we consider deterministic hidden-variables theories (such as the pilot-wave model) and their extension to " quantum non-equilibrium, " and we consider the continuous spontaneous localization model of wave function collapse. Other models are briefly discussed.
Coverage Analysis of Handoff Algorithm with Adaptive Hysteresis Margin

The handoff initiation in cellular systems depends on many environmental and system parameters. Various handoff initiation algorithms are available and most of them are based on relative signal strength (RSS) measurements. Some hysteresis margin in handoff decision criterion is allowed to avoid the ping-pong effect and hence frequent handoff requests from single user. The value of hysteresis margin plays a key role in handoff performance and affects the coverage of the cellular system. It is very difficult to choose a particular value for it. In this paper, the coverage of a handoff algorithm with dynamic hysteresis margin, based on the distance information between the mobile station and the serving base station, is analyzed for microcellular environment. Handoff probability is taken as performance parameter to evaluate handoff algorithms analytically.
Factors influencing online banking adoption: evidence from the Austrian market

Many bank customers are still reluctant to conduct their financial transactions online. The aim of this paper is to provide an improved understanding of determinants of online banking adoption in Austria. The authors propose a conceptual model that integrates perceptions of innovation characteristics and individual differences and report an empirical study with 372 bank customers in Austria. Logistic regression is used to analyse the data. The findings confirm the relevance of perceived innovation characteristics to online banking acceptance. Beyond that, the results suggest that internet trust and preference for personal contact are individual difference variables that predict online banking adoption.
Optimal Scheduling and Placement of Internet Banner Advertisements

The increasing popularity of the World Wide Web has made it an attractive medium for advertisers. As more advertisers place Internet advertisements (hereafter also called "ads"), it has become important for Web site owners to maximize revenue through the optimal selection and placement of these ads. Unlike most previous research, we consider a hybrid pricing model, where the price advertisers pay is a function of 1) the number of exposures of the ad and 2) the number of clicks on the ad. The problem is finding an ad schedule to maximize the Web site revenue under a hybrid pricing model. We formulate two versions of the problem - static and dynamic - and propose a variety of efficient solution techniques that provide near-optimal solutions. In the dynamic version, the schedule of ads is changed based on individual user click behavior. We show by using a theoretical proof under special circumstances and an experimental demonstration under general conditions that a schedule that adapts to the user click behavior consistently outperforms one that does not. We also demonstrate that to benefit from observing the user click behavior, the associated probability parameter need not be estimated accurately. For both of these versions, we examine the sensitivity of the revenue with respect to the model parameters.
Experimental Studies on Flow Characteristics around Circular Cylinder in Steady and Unsteady Flow

This paper describes on the airflow characteristics between steady and unsteady flow around the two dimensional circular cylinder in the range of Reynolds number of about 20,000~200,000. It is carried out wind tunnel testing. In the steady state experiment, it was measured maximum, minimum and mean pressure distribution data for 20 seconds by 100Hz. In the unsteady state, test condition is free stream with acceleration of 3m/s. When the corresponding Reynolds number was reached to the steady state, pressure data were acquired. From the result of test, unsteady flow has different characteristics of surface pressure distribution. Therefore, an accelerated flow is higher pressure drag than steady flow.

The - ary extended compact classifier system: Linkage learning in Pittsburgh LCS

A bracket assembly for supporting rollers to be received in tracks on a drawer includes a vertical wing and a horizontal wing integral with and projecting laterally from the lower edge of the vertical wing. At least two rollers are journaled on the vertical wing with one roller disposed adjacent each end of the vertical wing. A slot is formed transversely in the horizontal wing and a screw coacts with two flanges on the vertical wing, one on each side of the slot, whereby the screw may selectively move the flanges toward and away from each other thereby to change the width of the slot and adjust the relative positions of the rollers.
Towards Sustainable Energy Trends in the Middle East: A Study of Four Major Emitters

Energy is a key ingredient to facilitate economic development in the Middle East. Expectations for a rapidly growing economy in the next decade will likely cause an increase in the fraction of energy consumed domestically limiting what is available for export. These challenges are the biggest for resource-rich countries, since their economy is heavily dependent on fossil fuel exports alongside an energy-intensive economy. Thus, the paper addresses the question of how the development of energy systems among resource-rich countries has changed over the past three decades and what role can they play in the sustainable development of the region’s energy system and emission reduction goals? To address this question, we present an overview on energy trends in four resource-rich countries in the Middle East, which nearly account for 76% of the region’s energy-related emissions and about 77% of total energy consumption. These countries are namely, Iran, Saudi Arabia, Kuwait, and the UAE. Accordingly, we present a comparative energy analysis between the four countries through examining historical and current energy trends, the structure of energy supply, the status of renewable deployment and energy-related carbon dioxide (CO2) emissions. Results from the analysis showed that inefficient energy production and consumption have played a role in the deterioration of the energy landscape of the four countries compared to the global energy system. Thus, this highlights the necessity for suitable energy strategies and effective policies that will be central to sustainable energy development. The analysis presented here could be used to better understanding of the impacts of current gaps and inefficiencies in large energy consumers in the Middle East.
Symplectic Runge-kutta Schemes I: Order Conditions

Much recent work has indicated that considerable beneet arises from the use of symplectic algorithms when numerically integrating Hamiltonian systems of diierential equations. Runge-Kutta schemes are symplectic subject to a simple algebraic condition. Starting with Butcher's formalism it is shown that there exists a more natural basis for the set of necessary and suucient order conditions for these methods; involving only s(s + 1)=2 free parameters for a symplectic s stage scheme. A graph theoretical process for determining the new order conditions is outlined. Furthermore, it is shown that any rooted tree arising from the same free tree enforces the same algebraic constraint on the parametrised coeecients. When coupled with the standard simplifying assumptions for implicit schemes the number of order conditions may be further reduced. In the new framework a simple symmetry of the parameter matrix yields (not necessarily symplectic) self-adjoint methods. In this case the order conditions associated with even trees become redundant.
Estimating underlying energy demand trends using UK annual data

Employing the Structural Time Series Model (STSM) approach suggested by Harvey (1997), and based on annual data for the UK from 1967–2002, this paper reiterates the importance of using a stochastic rather than a linear deterministic trend formulation when estimating energy demand models, a practice originally established by Hunt et al. (2003a, 2003b) using quarterly UK data. The findings confirm that important non-linear and stochastic trends are present as a result of technical change and other exogenous factors driving demand, and that a failure to account for these trends will lead to biased estimates of the long-run price and income elasticities. The study also establishes that, provided these effects are allowed for, the estimated long-run elasticities are robust to the different data frequencies used in the modelling.
Non-binary LDPC coded OFDM in impulsive power line channels

In this paper, we propose Irregular Non-Binary Low Density Parity Check (IR-NB-LDPC) codes with Signed Log Fast Fourier Transform (SL-FFT) decoding algorithm to overcome the harsh environment of power-line communication (PLC) channels. Their performance is compared with Irregular Binary LDPC (IR-B-LDPC) codes using the Sum Product algorithm (SPA). The sparse parity check matrix H of both codes are constructed using progressive edge growth (PEG) algorithm with a novel initialization of the apriori log likelihood ratios (LLR) of each decoder to mitigate the highly impulsive noise in PLC channels. Numerical performance results obtained via simulations show that the proposed system at bit error rate of 10-4 achieves a coding gain of more than 21 dB compared to uncoded system and more than 6 dB compared to IR-B-LDPC codes for the same block length in bits and rates, however, this is accomplished with higher decoding complexity.
New and Notable Tau-ism : The Yin and Yang of Microtubule Sliding , Detachment , and Rupture

Traumatic brain injury is a nondegenerative, noncongenital insult to the brain caused by external mechanical forces. Recent studies suggest that even mild concussions—if repetitive—can trigger progressive neurological degeneration, a condition that is now widely known as ‘‘chronic traumatic encephalopathy’’ (1). Notably, chronic traumatic encephalopathy continues to progress even decades after the initial insult; the more severe the original injury and the longer the survival, the greater the severity of neurodegeneration. Progressive axonal damage and structural degradation are classic hallmarks of chronic traumatic encephalopathy. Strikingly, these symptoms appear to be shared by a number of other neurodegenerative diseases including Alzheimer’s disease and Parkinsonism. However, the molecular mechanisms of axonal failure remain poorly understood. One of the most common pathological features of traumatic brain injury is diffuse axonal injury (2). To date, the only method to reliably diagnose diffuse axonal injury is post mortem histopathology, where it manifests itself through extensive damage in white-matter tissue. More than half a century ago, experiments with gelatin molds have established that patholog-
Table tennis robot with stereo vision and humanoid manipulator I: System design and learning-based batting decision

In this paper, a 7-DoF robot table tennis system is presented, which adopts a stereo vision system as its perceptional sensor and a humanoid robot arm as its manipulator. The batting policy, which can return various incoming balls to a desired location, is learned through empirical data based on e-support vector regression(e-SVR). Two experiments, playing with a launcher machine and rallying with a human player, were carried out and the results verified the effectiveness of the proposed approach.
A PRACTICAL MINIATURIZED U-SLOT PATCH ANTENNA WITH ENHANCED BANDWIDTH

In this paper, an asymmetric U-slot patch antenna with low probe diameter is presented. It will be shown that reduction in probe diameter causes in reduction in bandwidth. One of the characteristics of this antenna is keeping the bandwidth in 30% in spite of reduction in antenna size and use of low probe diameter compared to antenna presented in (1). The presented antenna in this paper has been fabricated by pcb technique and tested. The far-field results have also been presented based on simulation and measurement. Although the antenna has high cross polarisation level, in the case of using circular polarisation, the use of this antenna can be recommended because of its reduced size, high impedance bandwidth, high total gain in spite of having low size, and ease of fabrication.
Comparison of self-reported attachment in young adults from Spain and the United States.

BACKGROUND Previous studies have provided mixed evidence in support of the structure of Bartholomew's attachment framework. The current study examined the comparability of the correlations among the attachment prototypes as well as the underlying factor structure of the Relationship Questionnaire in independent samples of Spanish and American young adults. METHOD Participants were 547 students from the Universitat Autònoma de Barcelona and 1425 from the University of North Carolina at Greensboro who completed the Relationship Questionnaire. RESULTS Secure attachment was negatively correlated with fearful attachment, as was preoccupied attachment with dismissing attachment. The secure-fearful association in the American sample represented a medium effect size, whereas the remaining correlations represented small effect sizes. Except for the secure-fearful association, the correlations among prototypes were comparable in magnitude across samples. A principal components analysis yielded two factors that explained similar amounts of variance in the two samples. The pattern of loadings was relatively comparable in both samples; however, it was not entirely consistent with the theoretical model. CONCLUSIONS The findings provided only partial support to the structure of the theoretical framework invoked. We discuss an alternative interpretation of the two factors, as well as further measurement considerations and directions for future research.
Lipid Domain Order and the Algebra of Morphology

Lipid membranes regulate the flow of materials and information between cells and their organelles. Further, lipid composition and morphology can play a key role in regulating a variety of biological processes. For example, viral uptake, plasma membrane tension regulation, and the formation of caveolae all require the creation and control of groups of lipids that adopt specific morphologies. In this paper, we use a simplified model mixture of lipids and cholesterol to examine the interplay between lipid phase-separation and bilayer morphology. We observe and theoretically analyze three main features of phase-separated giant unilamellar vesicles. First, by tracking the motion of `dimpled' domains, we measure repulsive, elastic interactions that create short--range translational and orientational order, leading to a stable distribution of domain sizes, and hence maintaining lateral heterogeneity on relatively short length scales and long time scales. Second, we examine the transition to `budded' domain morphologies, showing that the transition is size-selective, and has two kinetic regimes, as revealed by a calculated phase diagram. Finally, using observations of the interactions between dimpled and budded domains, we build a theoretical framework with an elastic model that maps the free energies and allowed transitions in domain morphology upon coalescence, to serve as an interpretive tool for understanding the algebra of domain morphology. In all three cases, the two major factors that regulate domain morphology and morphological transitions are the domain size and membrane tension.
New contribution to cosmological perturbations of some inflationary models.

We show that there are inflationary models for which perturbations in the energy momentum tensor, which are of second order in the scalar field, cannot be neglected. We first specify the conditions under which the usual first order perturbations are absent. We then analyze classically, the growth and decay of our new type of perturbations for one mode of fluctuations \de\phi k in the scalar field. We generalize this analysis, considering the contribution from the whole spectrum of \de\phi to a given wavelength of geometrical perturbations. Finally, we discuss the evolution of the perturbations during the subsequent radiation dominated era and discuss the resulting spectrum of density fluctuations. In the case of a massless scalar field we find a spectral index n=4. For massive scalar fields we obtain n=0 but the resulting amplitude of fluctuations for inflation around a GUT scale are by far too high. Hence, "conventional" inflationary models must not be influenced by this new type of perturbations, in order to lead to acceptable matter and CMB fluctuations.
Phonographic spelling errors in developmental language disorder: Insights from executive functions

The present study examined the executive functions and spelling performance of children with developmental language disorder (DLD) over a school year. Through a fine-grained spelling error analysis, we investigated whether the measured executive functions would distinguish children’s spelling profiles. The study comprised three groups: the DLD-S group (aged 7–9 years), including children with DLD matched on the total number of spelling errors produced on a dictation task with a typically developing group (n = 8); the DLD-AM group (aged 7– 9 years), including children with DLD matched on chronological age and phonological awareness skills with the DLD-S group (n = 8); and the typically developing group (n = 16; aged 7–8 years). The results indicated that both DLD groups tended to produce more phonographic errors (i.e., spelling errors that change the phonology of the word) even if the DLD-S group produced a similar number of errors in comparison with the typically developing group. In particular, the DLD-AM group made more phoneme omissions than the other groups. The DLD-AM group also had the smallest spelling improvement over the school year and the weakest updating ability. In contrast, all groups had similar inhibition and cognitive flexibility abilities. This may indicate that some children with DLD present limitations in updating, which may lead to a slower spelling acquisition and a greater number of phonographic errors. Language impairments affect and delay spelling acquisition, and the presence of an updating deficit may exacerbate this delay. 1 Université du Québec à Montréal, Faculty of Education Sciences, Department of Language Didactics, Montreal, Canada 2 Université du Québec à Montréal, Faculty of Education Sciences, Department of Specialized Education and Training * Author email address: godin.marie-pier@uqam.ca To cite this article: Godin, M. -P., Gagné, A. , & Chapleau, N.

Cosmology Solved? Quite Possibly!

The discovery of the cosmic microwave background (CMB) in 1964 by Penzias and Wilson led to the establishment of the hot big bang cosmological model some 10 years later. Discoveries made in 1998 may ultimately have as profound an effect on our understanding of the origin and evolution of the universe. Taken at face value, they confirm the basic tenets of inflation + cold dark matter, a bold and expansive theory that addresses all the fundamental questions left unanswered by the hot big bang model and holds that the universe is flat, slowly moving elementary particles provide the cosmic infrastructure, and quantum fluctuations seeded all the structure seen in the universe today. Just as it took a decade to establish the hot big bang model after the discovery of the CMB, it will likely take another 10 years to establish the latest addition to the standard cosmology and make the answer to “Cosmology solved? ” “YES! ” Whether or not 1998 proves to be a cosmic milestone, the coming avalanche of high‐quality cosmological data promises to make the next 20 years an extremely exciting period for cosmology.
