Parameter Identification for a Nonlinear Point-to-Point Model in the Context of Parametric Transductions

During the propagation of intense ultrasonic acoustic waves in fluid media, new frequencies are generated due to the nonlinearity of the fluid media. Among others, low frequency components are generated. These low frequency components are of particular interest for technical applications for the following reasons: The nonlinearly generated low frequency components are virtually radiated by an aperture which is much larger than the aperture of the physical transducer. This way, a high directivity can be obtained in the low frequency regime using physically small transducers. Furthermore, nearly the same bandwidth of the radiated ultrasonic wave is available in the low frequency regime. Thus, a high relative bandwidth can be created using transducers with a high Q factor. Additionally, since the channel attenuation is reduced at low centre frequencies, the nonlinearly generated low frequency wave can propagate over long distances.
State Incentive Spending and Large Establishment Spillovers

State governments spend over $30 billion a year to attract large establishments to their regions. The efficiency of such spending depends in part on the spillover effect of large establishments: do they attract smaller establishments and create indirect jobs? In this paper I quantify the effect of large establishments by estimating a model of small establishment location choice. I collect data from state budget documents and tax expenditure reports to document trends in state spending for large establishments, and exploit state incentive spending as an instrumental variable for large establishment location. I test whether governments are targeting establishments that will generate the largest positive externalities for the region by comparing industry-level spillover parameters with industry-level spending data. I find that states allocate 42% of their discretionary spending to industries with zero or negative spillovers, suggesting that a state could boost employment and revenue by reallocating subsidy spending across industries. ∗I am grateful for the support and guidance of Simon Anderson, Federico Ciliberto, Leora Friedberg, Gaurab Aryal, and and many other faculty and students at the University of Virginia.

Fractured identities: Exploring engagement and disengagement in the process of lifelong learning

In early childhood education and care, research indicates that quality experiences for young children are a result of the partnership between committed professionals who facilitate collaborative, high-quality programs and dedicated parents who are interested and involved in their child’s educational development (Stonehouse, 1994; Hutchins & Sims, 1999; Carr, 2003; Moss, 2003). Parent involvement in schooling is considered in post-modern times to be an antidote to failure, i.e., children are more likely to succeed if parents are actively involved (Ball & Vincent, 2001; Popkewitz, 2003). It is reasonable to argue that children’s disengagement can be a result of lack of interest by parents (Limerick, 1988; Education Queensland, 1999). The authors question this point arguing that, while effective partnerships are important, they do not always result in positive experiences for children in the schooling process from infancy to adulthood. In this paper, the authors examine the relationship between parent engagement in schooling and children’s success or failure as lifelong learners. The authors also use aspects of post-structuralist theory - particularly notions of problematisation, categorisation and thinking otherwise (Foucault, 1984c) - to argue that how children are produced as learners exerts a greater influence over their engagement or disengagement in the process of formal learning. Furthermore, it is argued that there are many other factors to consider when examining engagement of learners in the schooling process (MacNaughton, 2003). Narratives of children’s experiences are used to illustrate the formation of their identities as learners and the way in which these identities contribute to engagement, or otherwise, in the life long learning process.
Global high-resolution simulations of CO 2 and CH 4 using a NIES transport model to produce a priori concentrations for use in satellite data retrievals

Abstract. The Greenhouse gases Observing SATellite (GOSAT) measures column-averaged dry air mole fractions of carbon dioxide and methane (XCO2 and XCH4, respectively). Since the launch of GOSAT, model-simulated three-dimensional concentrations from a National Institute for Environmental Studies offline tracer Transport Model (NIES TM) have been used as a priori concentration data for operational near real-time retrievals of XCO2 and XCH4 from GOSAT short-wavelength infrared spectra at NIES. Although the choice of a priori profile has only a minor effect on retrieved XCO2 or XCH4, a realistic simulation with minimal deviation from observed data is desirable. In this paper, we describe the newly developed version of NIES TM that has been adapted to provide global and near real-time concentrations of CO2 and CH4 using a high-resolution meteorological dataset, the Grid Point Value (GPV) prepared by the Japan Meteorological Agency. The spatial resolution of the NIES TM is set to 0.5° × 0.5° in the horizontal in order to utilise GPV data, which have a resolution of 0.5° × 0.5°, 21 pressure levels and a time interval of 3 h. GPV data are provided to the GOSAT processing system with a delay of several hours, and the near real-time model simulation produces a priori concentrations driven by diurnally varying meteorology. A priori variance–covariance matrices of CO2 and CH4 are also derived from the simulation outputs and observation-based reference data for each month of the year at a resolution of 0.5° × 0.5° and 21 pressure levels. Model performance is assessed by comparing simulation results with the GLOBALVIEW dataset and other observational data. The overall root-mean-square differences between model predictions and GLOBALVIEW analysis are estimated to be 1.45 ppm and 12.52 ppb for CO2 and CH4, respectively, and the seasonal correlation coefficients are 0.87 for CO2 and 0.53 for CH4. The model showed good performance particularly at oceanic and free tropospheric sites. The high-resolution model also performs well in reproducing both the observed synoptic variations at some sites and stratospheric profiles over Japan. These results give us confidence that the performance of our GPV-forced high-resolution NIES TM is adequate for use in satellite retrievals.
Who is right-wing, and who just thinks they are?

This paper suggests that there are consistent patterns in how different groups of individuals perceive their relative ideological position. Using data from a large-scale cross-country survey on individuals views and personal characteristics it compares who reports themselves as being left(right) wing and who on an objective measure are actually left(right) wing. It finds, for example, the more educated on average believe themselves to be more left wing than their actual beliefs on a substantive issue might suggest.
BEYOND COMPLIANCE: FIRMS’ ENVIRONMENTAL BEHAVIOUR. A SURVEY

The relationship between firms and environment is complex. The impact that firms have on the environment include the use of primary resources to make products and the production of wastes and emissions. The impact of firms’ products on the environment, moreover, is not negligible. Environmental laws cannot, and should not, prescribe every decision taken by every business. Rather, consideration of environmental issues should be part of good business practice. Firms have, in fact, more than one reason for adopting environmentally responsible behaviour. This paper surveys the literature that analyze the circumstances under which firms can reconcile the apparently competing goals of increasing the expected value of their activity and internalizing external costs doing more than they are required to do under laws and regulations.
Estimation of the main fluid flow parameters of strombolian eruptions from acoustic measurements

The same way that we can hear that the wind is blowing faster or slower, we can hear when pouring water from a teapot that the water is hot, due to the coupling between fluid mechanics and acoustics. In volcanology we do not have direct access to the fluid flow, so we look for another way to estimate the magnitudes we are interested in. The objective is to estimate the four main fluid flow parameters of real eruptions (nozzle pressure ratio (NPR), nondimensional mass supply (L/D), Reynolds number (Re) and temperature ratio (Tr/T∞)) from acoustic measurements. More than 10 000 eruptions have been recorded at the Mount Etna and Stromboli with an array of 3 microphones to have the noise radiated in different directions. The governing parameters were estimated using existing correlations in the literature. Good agreement has been found between the acoustics radiated from the numerical simulations and the acoustics measured at the Mount Etna. Acoustic measurements of real eruptions were carried out estimating the governing parameters with the help of correlations from the literature. Numerical simulations of a starting free jet were performed and the radiated acoustics had a good agreement with the measured at the volcanoes.
Investigations of organic conductors by the Schegolev method

The Schegolev method is a well established technique to determine the dielectric properties of organic materials by placing the small samples in a microwave cavity and measuring the perturbation. The electronic properties can be studied without applying contacts and the frequency dependence gives information on the transport mechanism. The versatility of this unique method is reviewed by highlighting various applications on organic conductors and semiconductors.
COMPACT CPW-BASED ZEROTH-ORDER RESONANT ANTENNA WITH INTERLEAVING CRLH UNIT CELLS

This paper proposes a compact zeroth-order resonant (ZOR) antenna with improved gain and e-ciency. The proposed CRLH unit cell is based on the coplanar waveguide (CPW) structure. The proposed ZOR antenna is designed for a 2.45GHz frequency band, and it has the characteristic of monopolar radiation. Shunt inductance is implemented by microstrip short-circuit stubs, and a metal-isolator-metal (MIM) capacitator provides series capacitance, where a large capacitance can be achieved in a small footprint. The proposed antenna comprises two interleaving composite right-/left- handed CRLH unit cells, where the size of one unit cell is measured at only 0:12‚0 £ 0:098‚0. Because the fleld is loosely conflned within the CPW-based unit cell, a good antenna peak gain of 2.03dBi, and a radiation e-ciency of over 68% is achieved when fabricated on a thin substrate. The proposed antenna did not require an additional matching network, reducing the total antenna footprint. This paper presents antenna parameters such as the return loss, radiation pattern, antenna gain, and radiation e-ciency to validate the proposed design, which achieved good simulation results.
Residential Sorting and the Incidence of Local Public Goods : Theory and Evidence from Air Pollution

While the costs of environmental policies are generally thought to be regressive, the distribution of benefits is less understood. This paper explores the incidence of an unexpected decrease in air pollution in metropolitan Los Angeles by estimating the resulting change in housing costs and neighborhood demographics. The decrease in air pollution was caused jointly by the California Electricity Crisis of 2000 and the RECLAIM cap-and-trade program for NOx emissions and impacted neighborhoods differentially based on their location relative to major polluters and local wind patterns. I measure local exposure to this pollution shock using a dispersion model developed by atmospheric scientists which calculates the effect of individual firms’ emissions on the air quality of nearby locations. The estimates show that (a) housing rents increase significantly and as much as house prices; (b) 9% of low-income households leave the sample area due to improved air quality; and (c) low-income households are rarely home owners who would benefit from increased housing wealth. I show that a standard residential sorting model predicts that when low-income residents respond to improved amenities by leaving, the distribution of benefits from the improvement is likely regressive. Together, these results suggest that the distribution of benefits from improved air quality likely favors higher-income households. ∗Resources for the Future, Washington, D.C.

Effect of technology on the lives of 9-year old children

With the advancement of technology, researchers are more and more concerned about its impact on individuals, organizations, and society. In particular, the side effects of screen time have been a mounting large issue not only for researchers but for parents and educators. Although there have been several attempts to understand the phenomenon, but none focusing on a specific age. For this key reason, this study was conducted as a head start investigation in the Arab world. The target population was the cohort of 9-year children enrolled in private schools. The study sought to determine whether screen time is a predictor of participants’ academic performance, physical activity time, and other behaviors. Exactly 1175 families participated by completing a paper survey questionnaire by offering information about lived experiences with technology that is taking hold of their children’s minds and possibly shaping their lives. Unexpectedly, the results revealed that screen time variables contributed a substantively small, but statistically significant amount of explained variance to physical activity, academic performance, aggressive behavior, and sleep deprivation. Thus, there is strong empirical basis for where side effects of screen time occur, they are not detrimental to children’s lives in particular and culture in general. The computer science community should be aware of this reality and push forward for the design of technologies that enhance children’s overall wellbeing towards building better societies.
Free Essay Samples Mexico vs . America Standard Of Living

or the community in terms of material things which incorporates factors such as the housing, income growth inequality, safety, environment, civic engagement, employment, education and healthcare among other factors. Therefore, these factors differ among countries since due to different policies, leadership and the drive of the citizens towards the stability of the country in terms of finances and development. Further, there are factors that lead to prevalent differences in countries in terms of standard of living, and this includes the level of corruption, technology, and poor policies in a country. Standard of living present an important issue in the contemporary society and thus it requires an exploration through comparing Mexico vs. America in this paper.
INTRODUCING A VIBRANT TECHNIQUE TO REVIEW OBSERVATIONS IN SOCIAL MEDIA

Because of huge volume of user-produced data on social networking services, the study subjects on reducing the data overload difficulty and finding functional understanding have attracted much attention within the recent occasions. A great deal of systems suggested strategies to construct a number of kinds of summaries on comment streams. Within our work we concentrate on comment stream added for just one message on social networking services and goal to create immediate review of comments. For each one of the social message, our most significant purpose would be to cluster comments by related content together and convey a tight opinion summary intended for this message. Hence we advise an Incremental Short Text summarization approach that may incrementally update clustering results by newest incoming comments instantly. This suggested approach has the capacity to preserve clustering consequence of earlier phase, and also to incrementally update clustering result by way of recently-incoming comment. The suggested product is almost parameter-free and may handle outlier problem also it can generate clustering results by newest incoming comments instantly.
: International Perspectives on Worldviews in

The theme of this Special Issue is “International perspectives on worldviews in education”. In literature, “worldviews” are often considered to be sets of beliefs and assumptions that describe reality (Koltko-Rivera, 2004). Worldviews are a topic that has been researched from various perspectives and through various theoretical constructs in the past. For instance, worldviews have been in the interest of theology and humanistic studies, but various researchers have also called for a better understanding of the worldview functions in the field of educational psychology (e.g. Rauste-von Wright, 1986; Hirsto, 2001a, 2001b; Koltko-Rivera, 2004;). In line with this, the special issue combines several perspectives from diverse contexts to the exploration of worldviews. In this introduction, these perspectives are combined by examining the meaningmaking and learning processes in relation to different conceptualisations in the case studies concerning worldview.
Modelling Multiphase Induction Motors for Electric Ship Propulsion Systems

The naval integrated power systems often utilize electrical machines with large number of phases and magnetic poles. The detailed computer models of electric ship propulsion motors are particularly useful for predicting the electro-mechanical and electrical transients. This paper describes a coupled-circuit physicalvariable modelling of multiphase induction motors, which has similar accuracy as the conventional qd models but is easier to generalize and interconnect to the power electronic networks. The equations for the self and mutual inductance matrices for a machine with an arbitrary number of phases and/or phase groups on the stator and the rotor are presented. The paper describes the 3-, 6-, 9-, and 15-phase motor models and compares the simulated transients. It is shown that the motors with higher number of phases have a less severe torque ripple and the stator current increase following a loss of one phase. The proposed models can also be used for transient studies involving loss of multiple phases and/or inverter legs, inverter-motor interaction, switching harmonics, torque ripple, multiple faults, system-level studies, survivability, reconfiguration, etc. Key-Words: naval electric systems, electric ship, propulsion, multiphase, induction motors.
The extent of TQM practices in Ethiopian manufacturing firms: An empirical evaluation

Total Quality Management (TQM) practices are primarily found in developed countries but little has been written on how TQM has been applied in least developed countries like Ethiopia. This study aims to investigate the status and levels of TQM practices among different manufacturing firms located in the industrial area of Addis Ababa, Ethiopia. The design of this research has quantitative approach. Six critical success factors for TQM practices were identified and a survey instrument was developed. The questionnaire consists of 61statements, on a five-point Likert scale, to represent all the six critical success factors. From 300 sampled medium and large manufacturing firms a total of 122 valid responses were received. The survey findings are analyzed using statistical analysis package SPSS 20.0. Attempts at finding significant differences between medium and large companies were made. The result reveals that there no significance difference between medium and large companies on the levels of TQM practices. It also revealed areas lacking in implementation among manufacturing firms in Ethiopia. Manufacturing firms must be able to adopt TQM to help them meet world-wide challenges in the long run.
