Investigations for Performance Improvement of X-Shaped Rmsa Using Artificial Neural Network by Predicting Slot Size

In this paper, an application of artiflcial neural network based on multilayer perceptron (MLP) model is presented for predicting the slot size on the radiating patch for improvement of the performance of patch antenna. Several performance afiecting parameters like resonance frequencies, gain, directivity, antenna e-ciency, and radiation e-ciency for dual band frequency are observed with the variation of slot size. For validation of this work, a prototype X-shaped patch antenna is fabricated using glass epoxy substrate and its performance parameters are measured experimentally and have been found in good agreement with ANN and simulated values.

Should we drop covariate cells with attrition problems

It is well known that sample attrition can lead to inconsistent treatment effect estimators even in randomized control trials. Standard solutions to attrition problems either rely on strong assumptions on the attrition mechanisms or consider the estimation of bounds, which may be uninformative if attrition problems are severe. In this paper, we analyze strategies of focusing the analysis on subsets of the data with less observed attrition problems. We show that these strategies are asymptotically valid when the number of observations in each covariate cell goes to infinity. However, they can lead to important distortions when the number of observations per covariate cell is finite.
Executive Functioning in Provoked Physical Aggression

EXECUTIVE FUNCTIONING IN PROVOKED PHYSICAL AGGRESSION Angèle MacTavish Advisor: University of Guelph, 2011 Dr. Karl Hennig Executive functions (EF) are higher-level control processes that regulate lower-level processes to shape complex performance. Although remaining an elusive construct, researchers have dichotomized EF into “cool” cognitive processes, such as cognitive flexibility, and “hot” emotional processes, such as decision-making. The current study investigated both “cool” and “hot” EF as moderators of the relation between provocation and aggression. Undergraduate participants (N = 224) completed measures of “cool” and “hot” EF. Aggression was measured using a modified version of the Taylor Aggression Paradigm in which participants blasted an ostensive “partner” after receiving positive or negative feedback. The Wisconsin Card Sorting Task was associated with aggression for males, but not for females; the Trail Making TestPart B was not related to aggression; the Iowa Gambling Task was the strongest predictor of aggression for both genders. Findings highlight the importance of including measures of “cool” and “hot” EF in the assessment of aggression.
On the approximation of the principal eigenvalue for a class of nonlinear elliptic operators

We present a finite difference method to compute the principal eigenvalue and the corresponding eigenfunction for a large class of second order elliptic operators including notably linear operators in nondivergence form and fully nonlinear operators. The principal eigenvalue is computed by solving a finite-dimensional nonlinear min-max optimization problem. We prove the convergence of the method and we discuss its implementation. Some examples where the exact solution is explicitly known show the effectiveness of the method.
Quantum correlations in a noisy neutron interferometer

We investigate quantum coherences in the presence of noise by entangling the spin and path degrees of freedom of the output neutron beam from a noisy three-blade perfect crystal neutron interferometer. We nd that in the presence of dephasing noise on the path system the entanglement of the output state reduces to zero, however the quantum discord remains non-zero for all noise values. Hence even in the presence of strong noise non-classical correlations persist between spin and path of the neutron beam. This indicates that measurements performed on the spin of the neutron beam will induce a disturbance on the path state. We experimentally demonstrate this disturbance by comparing the contrasts of the output beam with and without spin measurements of three neutron interferometers with varying noise strengths. This demonstrates that even in the presence of noise that suppresses all entanglement, a neutron interferometer still exhibits uniquely quantum behaviour.
A Study Of Generating Abstract Test For Requirement Validation Among Requirement Engineers

Requirements testing or requirements-based testing (RBT) is one of the software testing techniques that is found effective to test requirements’ completeness and accuracy. This technique involves systematic way of test case generation from the model of the requirements specification. This technique has been applied in the requirements analysis phase to detect and eliminate requirements defects before the next stage of software development project. Although this technique is useful, it is tedious and time consuming to manually generate abstract test from the requirements model. However, we argue that the tedious process can be minimised if the requirements engineer have the good ability (skill) to generate abstract test from requirements models for requirements validation. This paper described a study of requirements engineer manually generate abstract tests from requirements model: Essential Use Cases (EUC) model. From the result, we discover that software requirements engineers are not well equipped with the skill and technique to generate abstract tests from requirements model.
A role for biotic filtering in driving phylogenetic clustering in soil bacterial communities

Aim Phylogenetic clustering, the coexistence of evolutionarily related organisms, appears to be common in soil bacteria. This pattern has traditionally been attributed to the habitat-filtering of bacteria that are able to survive under particular abiotic settings. According to the modern coexistence theory, however, phylogenetic clustering can also arise from biotic interactions such as the competitive exclusion of large clades with low competitive abilities. Here, we used phylogeny-based methods to discern whether the coexistence of evolutionarily related soil bacteria results from abiotic and/or biotic filtering. Location Worldwide. Methods We performed a Bayesian meta-analysis based on a literature review (n = 231) to assess whether the net relatedness index (NRI) or the nearest taxon index (NTI), two measures of the phylogenetic relatedness of taxa in local assemblages, deviate from those in randomly configured communities. We then sought the best abiotic (pH, total organic carbon and total nitrogen) and biotic predictors (relative abundance of Proteobacteria, Actinobacteria and Acidobacteria )o fNRI and NTI. Results Phylogenetic clustering is pervasive in soil bacterial communities regardless of the spatial and taxonomic scales (NRI = 2.29; 95% CI [1.43, 3.29]; P < 0.001). Clustering is accentuated by productivity; that is, more fertile soils hold communities with more closely related bacteria (estimate = 1.05 [0.03, 2.15]; P < 0.05). Proteobacterial abundance, which increases with organic carbon enrichment, leads to higher relatedness among coexisting bacteria (estimate = 0.1 [0.02, 0.17]; P < 0.01) through the competitive exclusion of distantly related deepbranching clades. Main conclusions Our results, together with the dominance of proteobacterial lineages in soils worldwide, suggest that the overrepresentation of this clade underlies the widespread coexistence of phylogenetically related bacteria. These results are consistent with phylogenetic clustering arising via differences in competitive ability as predicted by the coexistence theory. This supports the idea that biotic filtering might have a role in driving the phylogenetic community assembly of soil
Tools for linguloid taxonomy: the genus Obolus (Brachiopoda) as an example

This study points out some basic problems of linguloid systematics and proposes solutions for them. A taxonomic examination of the unique species of the genus Obolus found in the Upper Cambrian of Estonia and Russia, O. apollinis (= O. ruchini, O. transversus, O. rebrovi and Ungula convexa) is used as an example of a methodology employing all of the characters valid for distinguishing species of both extant and fossil Lingulidae. These characters are: - umbonal region; - body musculature; - septa or ridges; - main mantle canals - as established and figured by EMIG (1982, 1983) and BIERNAT and EMIG (1993). All of them have been determined to be taxonomically stable and have been studied and compared to take into account intraspecific variability; they should be used to describe or to redescribe any taxon of the superfamily Linguloidea. Characters of the shell and valves, such as shape, size, and dimensional ratios have no taxonomic value.
A Value Model for Depressive Symptoms and Hopelessness among University Students in Turkey.

3 Faculty of Education, Cukurova University, Adana Turkey. Email: okutlu@cu.edu. tr Abstract This study aimed to examine which values predicted depressive symptoms and hopelessness in Turkey. While it was hypothesized that values emphasizing universalism, benevolence, conformity, security, tradition, spirituality, self-direction, and achievement would predict lower levels of depressive symptoms and hopelessness, those values emphasizing power, stimulation, and hedonism would predict higher levels of depressive symptoms and hopelessness. Participants were 712 university students in Turkey. The Schwartz Values Survey Revised Turkish Version, the Beck Depression Inventory, and the Beck Hopelessness Scale were administered. Spirituality was observed as a distinct value category in Turkish culture. Higher levels of universalism predicted lower levels of depressive symptoms. While higher levels of self-direction and benevolence predicted lower levels of hopelessness, higher levels of achievement predicted higher levels of hopelessness. The findings partially fit Sagiv and Schwartz’s value theory regarding the relationship between mental health and the growth and deficiency aspects of values. The findings suggested having congruent values with the environment (i.e. achievement) were not uniformly associated with positive affective states.
Epidemiology of Completed Suicides Referred to Forensic Pathology Organization of Tehran, Iran, During March 2011 to March 2016

Background: Completed or successful suicide is the worst outcome of suicide attempts. This study is an epidemiologic investigation of successful suicides in Tehran, Iran. Methods: In this routine-data-based study, the records of successful suicides in Forensic Pathology Organization of Tehran were investigated with respect to confidentiality of information during March 2011 to March 2016. The obtained data were analyzed by SPSS 11.5. Statistically significant level was considered at less than 0.05. Results: A total of 1773 cases with mean (SD) age of 33.19(13.11) years and male-to-female ratio of 3.1 were included in the study. The mean age of male victims was greater than that of female ones (P=0.01). Of victims, 821(46.3%) were single and 807(45.5%) were unemployed/housewife. Methods of suicide were hanging in 962(54.6%), poisoning in 640(35.8%), falling in 88(5%), burning in 35(2%), shooting in 29(1.6%) and others in 19(1%) cases. Of poisoned cases, 283(44%) were victims of aluminum phosphide ingestion. Generally, frequency of married victims was greater than single ones but by comparing genders, relative frequency of single victims was greater among males (P<0.001). There was statistically significant association between suicide methods and age (P=0.001), gender (P<0.001), and occupation (P<0.001) of victims. Among different methods, shooting and poisoning were used by the youngest cases. Relative frequency of females was greatest in victims of burning and poisoning. Regarding occupational categories, poisoning was most frequent in students. Conclusion: In this study, the majority of successful suicides happened in people with occupational uncertainty, thus preventive measures should prioritize this issue. It seems that women with marital problems are also prone to suicide and social support programs should target this group, too. Association between the method of suicide and demography of victims will help us to recognize common methods in various groups of the society and establish appropriate preventive measures. While limiting access to supplies of suicide (like legislation on distribution of drugs for prevention of poisoning) is valuable, fundamental interventions at community level will be more effective in prevention of all kinds of suicide.
Surface prediction using rejection sampling to handle non- linear relationships

We demonstrate accurate surface predictions by imposing consistent physical and stochastic relationships between surfaces. The accuracy is improved by using all relevant information collected in wells: well markers, zone logs in horizontal sections, and gas/fluid content along wells. The conditioned surfaces are used to provide estimates of gross rock volumes of oil and gas reservoirs. In particular, we show how spill point and zone log information affect trapped volumes. We apply plain rejection sampling techniques to deal with the highly non-linear relationships between a surface and its spill point. For well path conditioning we build upon an extension of kriging to treat inequality constraints, based on an efficient rejection sampling from a high dimensional truncated multivariate Gaussian distribution. A fast approximate approach to simulating surfaces is presented and successfully applied to estimate volumes. The impact on gross rock volume distributions from different assumptions and data types is demonstrated by several examples and the uncertainties in all the involved data types are consistently handled and quantified.
An analysis of the energetics and stormwater mediation potential of greenroofs

OF GREENROOFS by ROGER N. HILTEN (Under the Direction of E. W. Tollner) ABSTRACT A study was conducted to examine the effects induced by a greenroof installation on a typical roof in various climate types of the United States. Initially, heat and moisture transport parameters of a modular greenroof system were evaluated based on physical measurements and simulated soil hydraulics. Using climatic data, the greenroof system was then evaluated to determine the stormwater runoff reduction potential compared to a BUR (Built-Up Roof) and overall energy load effects compared to a BUR and a reflective, “cool” roof in seven U.S. evaluation cities. Runoff simulations were run in HYDRUS-1D, while energy load simulations were run for a hypothetical office building in the evaluation cities using eQuest, a DOEdeveloped building energy load simulation. Simulation results were validated based upon in situ observations at a greenroof installation in Athens, Georgia. Simulated runoff and cooling load reductions for the evaluation cities ranged from 17-81 % and 2.5-6.9 %, respectively.
Exchange-biased planar Hall effect sensor optimized for biosensor applications

This article presents experimental investigations of exchange-biased Permalloy planar Hall effect sensor crosses with a fixed active area of w×w=40×40μm2 and Permalloy thicknesses of t=20, 30, and 50nm. It is shown that a single domain model describes the system well and that the thicker film will have a higher signal as well as a lower noise. It is estimated that the signal-to-noise ratio for bead detection increases by a factor 2.1 when t is increased from 20to50nm and hence a higher t is beneficial for biosensor applications. This is exemplified with calculations on M-280 Dynabeads®.
3D modeling for as-built buildings

This paper introduces a low-cost and efficient approach to generate 3D models for as-built buildings. Image-based modeling as a passive is an alternative of 3D model generation without a threat of destructive impact to the modeled object. This paper demonstrates the applicability of image-based modeling for as-built buildings in the main campus of National Chung Hsing University. The 3D model of campus was established by image-based modeling technology due to its low cost, time-efficiency, convenience, and low requirement. A consumer camera (Canon PowerShot S100) mounted on a UAV and held in hands was used to capture aerial photographs and side shots. The 3D printed product of NCHU campus as a gypsum statue was generated through a 3D printer, color CometrueJet T52, for demonstration.
Self-Cultivation and Meaning through the Experience of Injury Rehabilitation: A Case Study of Two Female Basketball Players

This case study involved interviewing athletes who had sustained moderate to severe injuries about the experience of being injured and the potential for self-cultivation and meaning synthesized through recovering from an injury. Two female intercollegiate basketball players were interviewed at the beginning of their rehabilitation and again at the end after successfully recovering and returning to sport. Data analysis revealed unique characteristics about the rehabilitation process with respect to loss of control, social support and learning about their confidence, motivation, perseverance, attitude, and resiliency. This article examines the experiences of these athletes as they navigated through the rehabilitation process and highlights the potential for the creation of a positive learning experience and self-cultivation that injured athletes can discover through the experience of recovering from an injury.
Privacy Preserving from global eavesdropper in Wireless Sensor Network Using Routing Technique

Various sensor network security schemes care for the content of messages, while the related information is left defenceless by divulge the location of the monitored objects. Preserving location privacy is essential and one of the largely challenging problems in lots of mission crucial sensor network applications. Previous solutions are principally designed to defend privacy from regional attackers who eavesdrop on traffic in a petite region at a moment. However, they can be effortlessly defeated by abundantly motivated global attackers that be able to trace the entire network’s communication proceedings. Although a few topical privacy solutions are proposed adjacent to global attackers, they experience from significant communication transparency as they inject dummy traffic or send messages in a globally synchronized method. As a result, they devour a lot of energy to maintain a required privacy level that craft the network lifetime diminutive. We propose an energy-efficient source location privacy preserving solution, handle the Energy Efficient Location Privacy method beside global attackers (E-LPG). E-LPG hides inventive source locations through a spatial scatter of messages with stealthy wormholes and owing to a temporal scatter using random setback when endorsed With a imperfect number of wormholes, E-LPG can accomplish a high privacy level lacking incurring further communication overhead. We evaluated the effectiveness and efficiency of E-LPG owing to theoretical analysis and general simulations. We have shown that E-LPG also generate dramatic synergistic consequence when used among other privacy schemes accompaniment.
The association between blood pressure and lipid levels in Europe: EURIKA

Objectives: Several studies have suggested a positive association between serum lipid levels and blood pressure (BP). This study investigated this association in a large population from 12 European countries. Methods: Data were taken from the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA; ClinicalTrials.gov identifier: NCT00882336). Associations between BP and lipid levels in patients free from cardiovascular disease (CVD) and with at least one major CVD risk factor (N = 7641) were assessed using linear regression analyses. Results: Overall, 72.8% and 64.8% of patients had hypertension and dyslipidaemia, respectively; 47.0% had both conditions. Regression coefficients (95% confidence interval [CI]) for the associations of low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, total cholesterol and apolipoprotein B levels with systolic BP, adjusted for age, sex and body mass index, were 0.93 mmHg/mmol/L (0.54 to 1.31), 1.07 mmHg/mmol/L (0.73 to 1.40), 1.02 mmHg/mmol/L (0.69 to 1.35) and 4.94 mmHg/g/L (3.43 to 6.46), respectively. The corresponding values (95% CI) for the associations with diastolic BP were 0.96 mmHg/mmol/L (0.73 to 1.19), 0.95 mmHg/mmol/L (0.75 to 1.15), 0.87 mmHg/mmol/L (0.67 to 1.07) and 4.33 mmHg/g/L (3.42 to 5.23), respectively. Most of these associations remained significant whether patients were treated with statins or not. Conclusions: Small but statistically significant associations between lipid levels and BP were observed in a large, multinational European population. Further research is warranted to assess the causality of this association and its implications on the management of patients with both hypertension and dyslipidaemia.
