Speed Efficient Adder Using Quantum DOT Cellular Automata

The area and complexity are the major issues in circuit design. Here, we propose different types of adder designs based on Quantum dot Cellular Automata (QCA) that reduces number of QCA cells and area compare to previous designs. The quantum dot cellular automata can implement digital circuits with faster speed, smaller size and low power consumption. The QCA cell is a basic building block of nanotechnology that can be used to make gates, wires and memories. The basic logic circuits used in this technology are the inverter and the Majority Gate (MG), using this other logical circuits can be designed. In this paper, the adders such as half, full and serial bit were designed and analyzed. These structures were designed with minimum number of cells by using cell minimization techniques. The techniques are using two cells inverter and suitable arrangement of cells without overlapping of neighboring cells. The proposed method can be used to minimize area and complexity. These circuits were designed by majority gate and implemented by QCA cells. Then, they simulated using QCA Designer. The Simulated results were verified according to the truth table. The performance analyses of those circuits are compared according to complexity, area and number of clock cycles and are also compared with previous designs.
Self-consistent Bulge/Disk/Halo Galaxy Dynamical Modeling Using Integral Field Kinematics

We introduce a method for modeling disk galaxies designed to take full advantage of data from integral field spectroscopy (IFS). The method fits equilibrium models to simultaneously reproduce the surface brightness, rotation, and velocity dispersion profiles of a galaxy. The models are fully self-consistent 6D distribution functions for a galaxy with a Sérsic profile stellar bulge, exponential disk, and parametric dark-matter halo, generated by an updated version of GalactICS. By creating realistic flux-weighted maps of the kinematic moments (flux, mean velocity, and dispersion), we simultaneously fit photometric and spectroscopic data using both maximum-likelihood and Bayesian (MCMC) techniques. We apply the method to a GAMA spiral galaxy (G79635) with kinematics from the SAMI Galaxy Survey and deep g- and r-band photometry from the VST-KiDS survey, comparing parameter constraints with those from traditional 2D bulge–disk decomposition. Our method returns broadly consistent results for shared parameters while constraining the mass-to-light ratios of stellar components and reproducing the H i-inferred circular velocity well beyond the limits of the SAMI data. Although the method is tailored for fitting integral field kinematic data, it can use other dynamical constraints like central fiber dispersions and H i circular velocities, and is well-suited for modeling galaxies with a combination of deep imaging and H i and/or optical spectra (resolved or otherwise). Our implementation (MagRite) is computationally efficient and can generate well-resolved models and kinematic maps in under a minute on modern processors.
Refactoring the Code for Visualizing Protein Database Information in a 3D Viewer for Software Reusability

We have released five Java Application Programming Interface (API) packages for viewing three-dimensional structures of proteins from the Protein Data Bank. To this end, the user interface of an earlier version has been refactored in an object-oriented fashion, in which refactoring is the process of changing a software system to improve its internal structure, without altering the external behavior. Various GUI design and features have been provided conveniently thanks to the ModelView-Control (MVC) model, which is an architectural pattern used in software engineering. Availability: The source code and API specification can be downloaded from https://sourceforge.net/projects/j3dpsv/.
A Structural Equation Model for Analyzing the Impact of Environmental Turbulence on Non-Financial Performance

Environmental turbulence monitoring mechanisms have been acclaimed in the practitioner and academic literature for their potential to improve organizational performance. And because of the limited previous studies in Middle East area addressing the concept of environmental turbulence (ET) as a whole, and precisely the relation between ET and Non-financial performance (NFP) in mobile telecommunications (TLC) sector;The study aimed to investigate the impact of ET on NFP at firms of Mobile TLC sector in Jordan. To clarify this relationship among their constructs, a Structural Equation Model (SEM) was conducted to examine the model fit and hypotheses. Study population consisted of all firms of Mobile TLC sector in Jordan (ORANGE, UMNIAH and ZAIN). Study sample included all mobile TLC firms in Jordan (the three firms). The Unit of Sampling and Analysis included all managers, assistant managers and heads of departments working within these firms. Descriptive analytical method was used and a questionnaire was constructed for data collection. A number of results were reached: there was a significant impact of ET (Technological Turbulence & Competitive Intensity) on NFP, a significant impact of ET (Market Turbulence & Competitive Intensity) on Customer Satisfaction, and a significant impact of ET (Technological Turbulence & Competitive Intensity) on Market Effectiveness at Jordanian Mobile TLC firms.The study recommended the need for firms under study to enhance the role of environmental screening of the external environment on ongoing basis to keep pace with technological changes, as well as the competition intensity in the Mobile TLC field environment.
Labor Standards and Economic Integration in the European Union: An Empirical Analysis

This study is motivated by frequent calls to harmonize labor standards across countries, which result from the fear that economic integration (and the accompanying liberalization of trade flows) will lead to an erosion of working conditions, as countries deliberately try to reduce labor standards in order to maintain competitiveness. We empirically examine the conventional wisdom that labour standards are important determinants of trade performance and whether there has been a “race to the bottom” of standards across EU-15 countries with deeper integration. Our panel data estimates for the period 1980-2001 provide mixed evidence regarding the conventional wisdom and “σ-convergence” in labor standards.
Impact of Mutual Coupling and Polarization of Antennas on BER Performances of Spatial Multiplexing MIMO Systems

This paper is aimed at studying the impacts of mutual coupling, matching networks, and polarization of antennas on performances of Multiple-Input Multiple-Output (MIMO) systems employing Spatial Multiplexing (SM). In particular, the uncoded average Bit Error Rate (BER) of MIMO systems is investigated. An accurate signal analysis framework based on circuit network parameters is presented to describe the transmit/receive characteristics of the matched/unmatched antenna array. The studied arrays consist of matched/unmatched compact copolarization and polarization diversity antenna array. Monte-Carlo numerical simulations are used to study the BER performances of the SM MIMO systems using maximum-likelihood and/or zero-forcing detection schemes. The simulation results demonstrate that the use of matching networks can improve the BER performance of SM MIMO systems significantly, and the BER performance deterioration due to antenna orientation randomness can be compensated by use of polarization diversity antenna arrays.
Survey Data as Coincident or Leading Indicators

In this paper we propose a monthly measure for the euro area Gross Domestic Product (GDP) based on a small scale factor model for mixed frequency data, featuring two factors: the first is driven by hard data, whereas the second captures the contribution of survey variables as coincident indicators. Within this framework we evaluate both the in-sample contribution of the second survey-based factor, and the short term forecasting performance of the model in a pseudo-real time experiment. We find that the survey-based factor plays a significant role for two components of GDP: Industrial Value Added and Exports. Moreover, the two factor model outperforms in terms of out of sample forecasting accuracy the traditional autoregressive distributed lags (ADL) specifications and the single factor model, with few exceptions for Exports and in growth rates.
Real-Time Collaboration over the Internet: What Actually Works?

In order to provide teachers and students with electronic learning environments that support mentoring and collaboration through electronic means, the authors developed software that supports same time/different place educational collaborative activities over the Internet. These activities focus on teaching students how to organize and systematize their explorations for information and to share this information with members of a group. The software is composed of an interface that connects the hyperlink, text, graphics, video, and sound capabilities of a browser to a World Wide Web client-server environment and is augmented by local electronic help tools and computer supported collaborative tools. Collaborative activities are supported through specially designed whiteboard, chat, file, and application sharing tools. Students can access online schedules and determine whether faculty or other students are available. The system is also equipped with management and record keeping capabilities that allow teachers or trainers to analyze various collaborative activities. Students enrolled in a variety of courses at the University of North Texas used the system to collaborate with other students and teachers. Information was logged concerning overall student performance, activities performed while using the collaborative systems, and attitudes related to technology and collaboration. Results were analyzed to determine which factors contributed to successful/unsuccessful collaboration.

Some researchers argue that both structural and cultural problems impact effectiveness, while others suggest that a lack of "critical mass" may be affecting the results. This paper suggests that all of these things are true. In also contends that the type of task required of the group and collaborative style influences effective real-time collaboration. While this paper confirms that collaborative interfaces help most people work more effectively, it also shows that some groups are less successful, have fewer interactions, and remain hostile towards the system even though they complete the required task. More importantly, the results of our research raise additional questions about how technology can support distributed groups, and what is the nature of the
Simulation Of 3-Ph To 3-Ph Cycloconverter Fed Variable Speed Drive

With harmonic distortion becoming an ever increasing concern in Variable Speed Drive (VSD) applications, virtually all Drive, manufacturers now consider limiting the generation of input current harmonics to be an important issue in their designs. This has led us to the introduction of various drives which should give us considerable reduction in the harmonic distortion. In practical application, the three-phase to three- phase cycloconverter is commonly required to derive a three- phase output from a three- phase input. The most logical method for producing a three-phase output is to use three symmetrical independent dual converters one for each output phase. As in the case of a rectifier or phase controlled converter circuit, from the view point of reducing the external harmonic voltages and current to a minimum, the pulse number of the cycloconverter circuit should be as high as possible. Cycloconverters enable conversion of AC power to AC power without any intermediate DC link. They are suitable for running induction and synchronous motors. Depending on their topologies they can drive both single-phase and three-phase motors. This paper simulates the working of an induction motor drive with a three- phase to three-phase Cycloconverter. The simulation was carried out using MATLAB-Simulink.
Efficacy and Reusability of Commercial Adsorbent for Isolation of Proanthocyanidins from Hot Water Extract of Pinus radiata Bark

This study was carried out to investigate the feasibility and usefulness of a commercial synthetic adsorbent, Diaion HP 20, for the isolation of proanthocyanidins (PAs) from hot water extract (HWE) prepared from Pinus radiata bark. Most ultraviolet (UV) absorbing materials in HWE were adsorbed onto Diaion HP 20 and easily recovered by simple ethanol (EtOH) washing. More than 50% of the UV absorbing materials were adsorbed within 20 minutes, and the adsorption equilibrium was reached within 3 h. The recovered materials from Diaion HP 20 were mostly composed of PAs, but some monomeric flavonoids such as taxifolin and unidentified hydrophobic materials were also adsorbed. The impurities such as carbohydrates and inorganic materials contained in HWE were mostly removed by Diaion HP 20. The adsorption ability of the UV absorbing materials onto Diaion HP 20 was almost the same as the first cycle even after 14 times of repeating cycles of adsorption and desorption. The radical scavenging ability of the recovered materials from the ad-sorbentwas slightly higher than that of thepure PAs prepared by Sephadex LH 20 from the same HWE.
Customer-perceived Value in Residential Developments: the Case of Hornsberg Strand, Sweden

This paper presents a new model by using a structural equation technique. This model integrates the productivity theory and customer-perceived value to identify key features that residential customers seek when making their decision to buy or rent a residential apartment. A theoretical structural equation model is confirmed by using a dataset based on 283 respondents, those who are potential tenants of an ongoing residential construction project in Sweden that consists of 402 rental apartments. The results show that expectations of being able to relax in the immediate neighborhood as well feeling safe in the neighborhood have a high impact on customer perceived value. Moreover, analysis of a two bedroom apartment, used as a show apartment, reveals that an apartment with plenty of natural daylight and a well proportional layout has the highest impact on customer perceived value. Professional developers and municipalities could use the proposed residential customer perceived value model (RCPV-model) to increase their understanding of customer-perceived values by verifying key drivers in successful residential projects and acting on them when planning new development projects.

TRANS-NEPTUNIAN OBJECTS WITH HUBBLE SPACE TELESCOPE ACS/WFC

We introduce a novel search technique that can identify trans-Neptunian objects in three to five exposures of a pointing within a single Hubble Space Telescope (HST) orbit. The process is fast enough to allow the discovery of candidates soon after the data are available. This allows sufficient time to schedule follow-up observations with HST within a month. We report the discovery of 14 slow-moving objects found within 5° of the ecliptic in archival data taken with the Wide Field Channel of the Advanced Camera for Surveys. The luminosity function of these objects is consistent with previous ground-based and space-based results. We show evidence that the size distribution of both high and low inclination populations is similar for objects smaller than 100 km, as expected from collisional evolution models, while their size distribution differs for brighter objects. We suggest that the two populations formed in different parts of the protoplanetary disk and after being dynamically mixed have collisionally evolved together. Among the objects discovered there is an equal-mass binary with an angular separation ∼0. ″53.
Interpersonal communication, voting behaviour and influence in an election campaign: The 2009 German elections

Interpersonal influence—the process by which people change their idea according to the ideas of others—is a crucial mechanism that forges political agreement among citizens. By using data from the 2009 German Longitudinal Election Study short-term campaign panel, it will be tested how this strategy contributes to changing citizens’ ideas in the proximity of the 2009 Bundestag elections in Germany. Results of fixed-effect logistic regression models confirm the findings in previous literature, showing evidences consistent with influence effects. It is also suggested that the social circle of discussants alters the way in which people are influenced. Propensities to change vote choice, in fact, are boosted by the exposure to disagreeable strong ties, such as relatives and spouse/partner.
ASSUMED STRESS-STRAIN QUADRILATERAL PLATE ELEMENTS BASED ON ANALYTICAL AND NUMERICAL INTEGRATION

On the basis of the first-order solid plate theory, proposed in earlier au- thors' articles, two assumed stress-strain ANS quadrilateral four-node solid plate ele- ments are developed. This paper generalizes the conventional assumed stress solid plate/shell finite element formulation because transverse shear strains are distributed in the thickness direction according to the linear law. Both quadrilateral ANS solid plate elements developed are based on the unified technique that allows assessing their advantages and disadvantages. It is worth noting that element stiffness matrices of elaborated quadrilaterals including a displacement-based ANS quadrilateral four-node element have six zero eigenvalues as required for satisfaction of the general rigid-body motion representation.
Dynamic Model and Analysis of Nonlinear Vibration Characteristic of a Curve-Face Gear Drive

To study the nonlinear dynamic characteristics of curve-face gear drive, a generalized nonlinear dynamic model based on Lagrange Bondgraphs was presented. The model considered the effects of the basic parameters of curve-face gear, such as meshing frequency, eccentricity k and the order number n1 of non-cylindrical gears. Utilizing this simulation model, the vibration characteristics of curve-face gears were analysed. It is indicated that the vibration response of the curve-face gear is more complex than that of the face gear due to the influence of external excitation. These characteristics determine that this gear pair cannot be applied directly to a transmission system with high speed. Finally, a related experiment was proposed to present the validation of the numerical model.
Adults' Financial Literacy and Households' Financial Assets: The Role of Banks Information Policies

We investigate the role of banks information policies in fostering the accumulation of financial knowledge. In Italy, banks belonging to the PattiChiari Consortium implement policies aimed at increasing transparency and procedural simplification, without offering services at lower cost with respect to other banks. We exploit this feature of the Italian banking system and show that these policies promote financial literacy. The increase in financial knowledge attributable to banks information policies significantly affects household financial assets. We use these policies as instruments to estimate the effect of financial literacy on financial assets, showing that it is significantly underestimated by OLS correlation.
A Dynamic Pricing Model for Coordinated Sales and Operations

Recent years have seen advances in research and management practice in the area of pricing, and particularly in dynamic pricing and revenue management. At the same time, researchers and managers have made dramatic improvements in operations and supply chain management. The interactions between pricing and operations/supply chain performance, however, are not as well understood. In this paper, we examine this linkage by developing a deterministic, finite-horizon dynamic programming model that captures a price/demand effect as well as a stockpiling/consumption effect – price and market stockpile influence demand, demand influences consumption, and consumption influences the market stockpile. The decision variable is the unit sales price in each period. Through the market stockpile, pricing decisions in a given period explicitly depend on decisions in prior periods. Traditional operations models typically assume exogenous demand, thereby ignoring some of the market dynamics. Herein, we model endogenous demand, and we develop analytical insights into the nature of optimal prices and promotions. We develop conditions under which the optimal prices converge to a constant. In other words, price promotion is suboptimal. We also analytically and numerically illustrate cases where the optimal prices vary over time. In particular, we show that price dynamics may be driven by both (a) revenue effects, due to nonlinear market responses to prices and/or inventory, and (b) cost effects, due to economies of scale in operations. The paper concludes with a discussion of directions for future research.
