Crosstalk Cancellation in Inductively Coupled Full-Duplex Data Transfer Systems by a single Multipole Dualport Coil Structure

Abstract. Short range inductive data transfer has become very popular in the last years with the increased interest in technologies like RFID and NFC. Additionally, wireless power transfer has been a field of intensive research and product development. In industrial applications, a combination of both is often needed to replace mechanical contacts, mainly for safety and reliability reasons, especially regarding spark prevention and maintenance reduction. In this paper, we present a compact inductive structure that can be implemented in an existing wireless energy transfer system. The structure is developed by field considerations, leading to a single structure comprising two signal ports that are decoupled from each other, but can be used to transfer a signal to a second structure of that kind with very small interference. An optimisation to achieve comparable channel characteristics is conducted by using 3-D field simulations. Subsequent measurements are conducted to verify the achieved performance.
Criteria for Evaluating Ophthalmology Departments Based on the U.S. News & World Report Ranking System

Abstract Purpose To propose a methodology for ranking U.S. clinical ophthalmology programs which utilizes an existing framework of both objective structural (or resource) information and outcome data as well as subjective reputational scores currently used by U.S. News & World Report for most clinical specialties. Design Evidence-based manuscript. Topic The U.S. News & World Report annual “Best Hospital Rankings by Specialty” provides the public with information regarding the relative strengths of U.S. medical and surgical departments in providing care and treatments for patients with complex diseases. For most medical and surgical specialties, these rankings are determined by considering a combination of objective structural (or resource) information and outcome data along with subjective reputational scores. Clinical Relevance In ophthalmology, U.S. News & World Report annual rankings are currently generated only from subjective reputational scores submitted by a small number of voting ophthalmologists. No objective clinical or outcome data are considered. Literature Reviewed Methodology for determining “Best Hospital Rankings by Specialty” utilized by RTI International on behalf of U.S. News & World Report. Results The ranking system of U.S. departments of ophthalmology presently employed by U.S. News & World Report presents an incomplete picture of the relative strengths and weaknesses of the departments listed. Conclusion With the changes in health insurance that increasingly shift decision-making responsibility and cost to consumers, providing mechanisms to allow the public to make informed decisions is an emerging imperative for ophthalmology and other specialties. Revision of the current “reputation-only” ranking system used for ophthalmology to also include objective clinical and outcome data would benefit patients by providing more accurate and impartial information on which to base their eye care decisions.

Tackling urban and rural food wastage in Southeast Asia: issues and interventions

Food wastage is prevalent in Southeast Asia and has significant implications for the regionâ€™s food, environmental and economic security. It is likely that the region wastes approximately 33 per cent of food, but accurate estimates are not available due to dearth of quantitative information. Wastage occurs at all stages of food supply chains from the point of production to post-harvest, retail and consumption. There has to be effective policies to for Southeast Asian governments to address rural and urban food wastage. [Policy Brief No. 17].

Reconstruction of four-dimensional rockfall trajectories using remote sensing and rock-based accelerometers and gyroscopes

Abstract. This work focuses on the in-depth reconstruction of the full set of parameters of interest in single-block rockfall trajectories. A comprehensive understanding of rockfall trajectories holds the promise to enhance the application of numerical models for engineering hazard analysis. Such knowledge is equally important to investigate wider cascade problems in steep terrain. Here, we present a full four-dimensional trajectory reconstruction of the “Chant Sura” rockfall experiment performed with EOTA221 norm rocks. The data analysis allows a complete kinematic description of a rock's trajectory in real terrain and underscores the physical complexity of rock–ground interactions. In situ accelerometer and gyroscope data are combined with videogrammetric and unmanned aerial-systems mapping techniques to understand the role of rock rotations, ground penetration and translational scarring in rockfall motion. The exhaustive trajectory reconstruction provides information over the complete flight path such as translational velocity vectors, angular velocities, impact duration and forces, ballistic jump heights, and lengths. The experimental data provide insight into the basic physical processes detailing how rotating rocks of general shape penetrate, rebound and scar ground terrain. In future, the data will serve as a calibration basis to enhance numerical rockfall modelling.
Technical Note: Simple formulations and solutions of the dual-phase diffusive transport for biogeochemical modeling

Representation of gaseous diffusion in variably saturated near-surface soils is becoming more common in land biogeochemical models, yet the formulations and numerical solution algorithms applied vary widely. We present three different but equivalent formulations of the dual-phase (gaseous and aqueous) tracer diffusion transport problem that is relevant to a wide class of volatile tracers in land biogeochemical models. Of these three formulations (i.e., the gas-primary, aqueous-primary, and bulk-tracer-based formulations), we contend that the gas-primary formulation is the most convenient for modeling tracer dynamics in biogeochemical models. We then provide finite volume approximation to the gas-primary equation and evaluate its accuracy against three analytical models: one for steady-state soil CO 2 dynamics, one for steady-state soil CH 4 dynamics, and one for transient tracer diffusion from a constant point source into two different sequentially aligned medias. All evaluations demonstrated good accuracy of the numerical approximation. We expect our result will standardize an efficient mechanistic numerical method for solving relatively simple, multi-phase, one-dimensional diffusion problems in land models.
Culture, Personal Autonomy and Individualism: Their Relationships and Implications for Personal Growth and Well-Being

The recent research and theorizing in cross-cultural social psychology have raised several interesting and conceptually important issues about the role of autonomy, selfdetermination and freedom of choice in different cultures and regarding the role of these factors in human functioning within various cultural contexts (Ahuvia, 2001; Inghilleri, 1999; Iyengar & DeVoe, 2003; Kagitcibasi, 2003, 2005; Markus & Kitayama, 2003; Miller, 2003; Rychlak, 2003; Schwartz, 2000). The following are among the key questions that have been raised: What is the nature and role of autonomy in the behavior of people from different cultures? Is autonomy’s positive influence only a prerogative of Western cultures built on the ideology of individualism? How does autonomy support relate to the psychological well-being (PWB) of people from different cultures? In this paper, I suggest answers to these questions and provide empirical evidence that support them.
Impact of busy lines and mobility on call blocking in a PCS network

Several analytical models have been proposed to study the blocking probability for personal communications service networks or mobile phone networks. These models cannot accurately predict the blocking probability because they do not capture two important features. First, they do not capture the busy-line effect. Even if a cell has free channels, incoming and outgoing calls must be dropped when the destination portable is already in a conversation. Second, they do not capture the mobility of individual portables. In these models, mobility is addressed by net hand-off traffic to a cell, which results in traffic with a smaller variance to a cell compared with the true situation. We propose a new analytic model which addresses both the busy-line effect and individual portable mobility. Furthermore, our model can be used to derive the portable population distribution in a cell. The model is validated against the simulation experiments. We indicate that the previously proposed models approximate a special case of our model where the number of portables in a cell is 40 times larger than the number of channels.
Usage and Research Challenges in the Area of Frequent Pattern in Data Mining

The core area to be concentrated is the minimal representation, contextual analysis and the dynamic identification of the frequent patterns.
Deflection of light in equatorial plane due to Kerr-Taub-NUT body

According to General Relativity, there are factors like mass, rotation, charge and presence of Cosmological constant that can influence the path of light ray. Apart from these factors, many authors have also reported the influence of gravitomagnetism on the path of light ray. In this study we have discussed the effect of a rotating Kerr-Taub-NUT body where the strength of the gravitomagnetic monopole is represented by the NUT factor or magnetic mass. We use the null geodesic of photon method to obtain the deflection angle of light ray for a Kerr-Taub-NUT body in equatorial plane upto the fourth order term. Our study shows that the NUT factor has a noticeable effect on the path of the light ray. By considering the magnetism to be zero, the expression of bending angle gets reduced to the Kerr bending angle. However, we obtained a non-zero bending angle for a hypothetical massless, magnetic body.
Lipid and selenium sources on fatty acid composition of intramuscular fat and muscle selenium concentration of Nellore steers

The objective of this study was to evaluate the effect of lipid and selenium sources in diets for finishing Nellore steers on the fatty acid composition and selenium concentration of the longissimus muscle. Fifty Nellore steers (body weight = 458±39 kg) were assigned to one of six dietary treatments: 1) diet containing sunflower seed and inorganic selenium; 2) sunflower seed and organic selenium; 3) whole cottonseed and inorganic selenium; 4) whole cottonseed and organic selenium; 5) soybeans and inorganic selenium; and 6) soybeans and organic selenium. Diets were formulated with the same amount of nitrogen and calories and supplied once daily to steers in collective pens, with three animals per pen, for 120 d. At the end of the trial, steers were slaughtered and samples of the longissimus muscle were collected for fatty acid and selenium analysis. Effect of selenium sources was detected for selenium concentration in the longissimus muscle. Organic selenium had higher concentrations in the meat compared with inorganic selenium. The total saturated, monounsaturated and polyunsaturated fatty acids did not differ between the sources of lipids and selenium. For selenium sources, no differences were observed between the concentrations of polyunsaturated fat. Also, no differences in C18:2 cis-9 trans-11 concentrations were noted; however, steers fed sunflower seed presented greater proportions of this fatty acid in the meat. The results indicated that the use of sunflower seed, cottonseed or soybeans and organic or inorganic selenium in feedlot diets to Nellore cattle does not alter the great part of the fatty acid profile of the longissimus muscle. However, the inclusion of sunflower seed in the diet increases the meat CLA cis-9, trans-11, which is desirable and beneficial for the health of consumers.
Statistical evaluation of topsoil heavy metal pollution around a lead and zinc production plant in Zanjan province, Iran

Heavy metal contamination around the National Iranian Lead and Zinc Company (NILZ) in Zanjan province was evaluated in this paper. Collected data were used to appraise the degree of soil contamination and also the source of pollution in the study area based on geoaccumulation index (Igeo), and enrichment factor (EF). The levels of Fe, Zn, Cd and Pb in the samples exceed those reported in literature. The analyzed soils can be considered unpolluted to moderately polluted by Cd and Pb, and moderately polluted by Zn. Evaluated EF also showed moderate to severe enrichment of the soil samples by Zn and Pb, and very strong enrichment by Cd. These results indicated an anthropogenic contribution mainly for Zn, Cd and Pb elements. Bivariate correlation among the investigated metals showed the contamination of soil around the study area resulted from NILZ activity of Company. Based on the Mann-Whitney assessment, it was found that the presence of Co, Cu, Zn, Cd and Pb was also attributed to the plant. Parametric and non-parametric tests revealed the leaching of metals to deeper soil layers. Hierarchical Clustering Analysis (HCA) allowed categorizing the investigated metals in three groups. These groups were cluster I (Zn, Cd, Co and Ni), cluster II (Pb and Cu) and Fe in an independent cluster III. Principal Component Analysis (PCA) and Factor Analysis (FA) elucidated the anthropogenic source of the pollutants.
Impact of Financial Distress on the Efficiency of Selected Manufacturing Firms of Ethiopia

Efficiency ratio has important implication on the solvency of manufacturing firms. Efficiency is how the firm uses its assets productively. Efficiency is measured in terms of income to asset ratio; it has great importance in addressing financial distress problem. With this in mind, the main objective of the study is to examine the relationship between efficiency and financial distress of manufacturing firms in Ethiopia for the period from 1999 to 2005. The researcher also explicitly reviewed the recent findings on efficiency-financial distress relationship up to 2015. Besides this the research examines various other factors affecting financial distress. Due to data heterogeneity, non-continuity and because the Hausman test favors it over the Random Effect technique, the panel data General Least Square (GLS) regression method is used. The result proves that efficiency has positive and significant influence on debt service coverage. Efficiency is the most important determinant for firms and firms should consider improving efficiency through retrenchment of obsolete and unproductive assets that decreases the capacity of generating return. Unproductive assets offset the profit generated by productive assets and decreases efficiency of firms. Keywords: Financial Distress, efficiency, debt service coverage, productivity, Ethiopia

Shape modeling and validation of stress-biased piezoelectric actuators

Piezoelectric composites with a characteristic initial curvature and accompanying residual stresses are capable of enhanced performance, relative to flat actuators. This paper utilizes Rayleigh–Ritz techniques with revisions regarding the effective in-plane resultant force and the effective bending moment. The Rayleigh–Ritz technique is based on the assumption that the stable geometric configuration developed in the actuator after manufacturing is the configuration that minimizes the total potential energy. This energy is a function of the displacement field which can be approximated by either a four-term model or a 23-term model. In this case, Thunder®, a composite of steel, polyimide adhesive, PZT, and aluminum is constructed with varying geometries so that three-dimensional surface topology maps are measured. Numerically, the four-coefficient model produces results that are not comparable to experimental data. The 23-coefficient model generally shows good agreement with the data for all studied actuators. In the case of actuators with a length to width ratio of one, simulations are close to experimental results. In the case of length to width ratios different to unity, the model accurately predicts the devices’ shape. It is further demonstrated that the curvature of the devices seems to follow the rolling direction of the stainless steel layer, challenging the isotropy assumption.
Research on Computer Architecture based on Distributed Cluster Structure

With the fast development of image science and embedded system technique, it is widely accepted that future HPC systems will be limited by their power consumption. The current high performance computing system is a commodity server processors, design for many years to achieve maximum performance, and then it dawned on energy efficiency. In this paper we advocate a different approach: computer architecture based on distributed cluster structure. We introduce the architecture of Tibidabo, the first large-scale HPC cluster built from ARM multicore chips, and a detailed performance and energy efficiency evaluation. We now design experience and to improve the energy efficiency of future HPC systems based on the low power core. The experimental result shows the effectiveness of our methodology, further in-depth research portion is also discussed with case studies.
Development of calibration strategies for the Simons Observatory

The Simons Observatory (SO) is a set of cosmic microwave background instruments that will be deployed in the Atacama Desert in Chile. The key science goals include setting new constraints on cosmic inflation, measuring large scale structure with gravitational lensing, and constraining neutrino masses. Meeting these science goals with SO requires high sensitivity and improved calibration techniques. In this paper, we highlight a few of the most important instrument calibrations, including spectral response, gain stability, and polarization angle calibrations. We present their requirements for SO and experimental techniques that can be employed to reach those requirements.
Cluster Policies and Firm Selection: Evidence from France

In this paper, we shed light on the selection of the benefi ciaries from the French competitiveness cluster policy which was launched in 2005 and extended to 2012. We disentangle the selection and self-selection eff ects, as emphasized in the theoretical literature on regional and industrial policy. Our main conclusion is that winners were (self-)selected at both steps of the procedure, and that this holds for the three cluster types: worldwide clusters , potentially worldwide clusters and national clusters . We thus provide a methodology which allows us to contrast the e ffective outcomes of the selection process and the official objectives of cluster policies in terms of targeting, and which thus helps in their econometric evaluation.
Blind Signal Processing for Wireless Sensor Networks

Abstract In indoor sensor networks equalization algorithms based on the minimization of Euclidean distance (MED) for the dis-tributions of constant modulus error (CME) have yielded superior performance in compensating for signal distortions inducedfrom optical fiber links, wireless-links and for impulsive noise problems. One main drawback of MED-CME algorithms is aheavy computational burden hindering its implementation. In this paper, a recursive gradient estimation for weight updates ofthe MED-CME algorithm is proposed for reducing the operations of the conventional MED-CME to at each iter-ation time for N data-block size. From the simulation results of the proposed recursive method producing exactly the sameresults as the conventional method, the proposed estimation method can be considered to be a reliable candidate for imple-mentation of efficient receivers in indoor sensor networks.
