Improved fuzzy vault scheme for fingerprint verification

Fuzzy vault is a well-known technique to address the privacy concerns in biometric identification applications. We revisit the fuzzy vault scheme to address implementation, efficiency, and security issues encountered in its realization. We use the fingerprint data as a case study. We compare the performances of two different methods used in the implementation of fuzzy vault, namely brute force and Reed Solomon decoding. We show that the locations of fake (chaff) points in the vault leak information on the genuine points and propose a new chaff point placement technique that makes distinguishing genuine points impossible. We also propose a novel method for creation of chaff points that decreases the success rate of the brute force attack from 100% to less than 3.5%. While this paper lays out a complete guideline as to how the fuzzy vault is implemented in an efficient and secure way, it also points out that more research is needed to thwart the proposed attacks by presenting ideas for future research

Accurate Binary Decisions For Assessing Coronary Artery Disease

Generalized linear models offer convenient and highly applicable tools for modeling and predicting the behavior of random variables in terms of observable factors and covariates. This paper investigates applications of a special case of generalized linear model to improve the accuracy of predictions and decisions adopting Bayesian methods, in the specific context of assessing coronary artery disease. The basic model is developed for this application using binary response. The results clearly demonstrate the potential advantages offered by this approach

WRESTLING IN TURKIC PEOPLES FROM A SOCIO-CULTURAL PERSPECTIVE

This monograph will address the following questions: “What was the perspective of Turkic peoples on wrestling branch of sports and what was the cultural aspect of wrestling for social structures and lifestyles of Turkic peoples? What type of a transformation did wrestle experience? What is its current state at national level?” Problem: The problem of this research pertains to the fact that the richness of traditional wrestling which is known to possess a deep-seated reputation in Turkish history of sports and occupy an affluent position in Turkish sports tradition is not well-reflected in the literature at national and international levels, its traditional cultural elements are lost along with globalization and it is likely to end up being almost erased from national memories. Objective: This modest study sought to find an answer to the question as to how Turkic peoples perceived traditional wrestling in religious, national, political, military, economic and social domains of life and aimed to incorporate the finding into the literature rightly. Methodology: From among qualitative research methods, descriptive and comparative research techniques were implemented in this study. Result: It was deduced that wrestling which was one of the primary activities in socio-cultural structures and lifestyles of ancient Turkic peoples was viewed as a social value and even as a social norm beyond being just a branch of sports, possessed embedded and rich rituals, but began to lose its meaning along with the disappearance of most of these rituals, and even if it was affected adversely by globalization, there still existed affection towards wrestling and the wrestler.  Article visualizations

CONSIDERING THE INEFFICIENCIES IN LABOR MARKET FOR AN EXPLANATION OF MIGRATION FACT FROM RURAL TO URBAN AREAS IN TURKEY

In this study, it is intended to explain determinant points between market price of labor and shadow price of labor and explain migration from rural to urban according to this wage difference. Unemployment or rigidity in urban labor market causes different wage level from equilibrium wage level. This high level wage increases alternative cost of rural against urban and encourages migration from rural to urban. The state of instigating the migration from rural to urban that causing by the increase on wages levels which is in proportion to secession of competition level has been calculated by considering the Turkey example for different sectors. Consequently, it has been determined that the wage level modified according to the distortion in competition is one of the factors effecting the migration to rural to urban.Shadow Price; Migration from Rural to Urban; Labor Market

Comparison of red blood profiles and oxygen transport capacity of elite and sub-elite wrestlers

This study aimed to compare the red blood profiles’ that are determinants of oxygen transports system, of elite wrestlers with sub-elite wrestlers. This study consists of a twenty-one elite wrestlers representing national team of Turkey who volunteered to participate in the study. Biochemical parameters were determined during transition period and the bloods were drawn in a resting state for each participant. A paired T tests was used to check the variations in hematological parameters. There are no significant differences between the groups except age. Elite wrestlers age was found to be significantly higher than sub elite wrestlers (p = 0.019 <0.005).  RBC, HGB, HCT, MCH, MCHC were within normal limits and also for athletes indicates a positive development and there were no significant differences between the groups. Training increases total hemoglobin mass by stimulating erythropoiesis, which increases the amount of O2 that can be carried by blood. regular screening of hematological variables is desirable as many athletes have values near or below the lower limit of the normal range

Revisión de las pautas biológicas de la gamba roja Aristeus antennatus a lo largo del Mediterráneo: comparación con un caso de estudio de la población de gamba de la bahía de Antalya en el Mediterráneo Oriental

During three surveys between September 2009 and June 2011, a total of 20867 specimens of A. antennatus were caught from the 127 successful hauls with a total towing time of 219.5 h. Carapace length ranged between 12-61 mm for females (mean length, 35.8±8.2 mm) and 14-35 mm for males (24.8±3.4 mm). The two-way MANOVA shoved that depth had a significant effect on the abundance (p 27 mm) were recorded in June, July and August. The monthly gonadosomatic index of A. antennatus females changed seasonally, reaching a maximum value between July and August. The length-weight relationships in female and male specimens exhibited a strong negative allometry. The monthly length-frequency distributions showed that females of A. antennatus exhibited a maximum of six modal size groups per year. The recruitment of young-of-the-year took place mainly between January-April. The fishing mortality, reference point (F0.1) of fisheries mortality and exploitation rate were 0.498 year-1, 0.444 year-1 and 0.524 year-1, respectively. The fishery activity and the biological aspects of A. antennatus in the Antalya Bay have a lot of common and non-common points with other areas of the Mediterranean Sea. The above-men-tioned differences could be attributed to the different oceanographic and environmental parameters in the present study area.Se realizaron tres campañas de muestreo entre septiembre de 2009 y Junio de 2011 en el golfo de Antalya. En ellas se capturaron un total de 20867 ejemplares de A. antennatus a partir de 127 lances efectivos realizados en un total de 219.5 h. La longitud del caparazón de las hembras se mantuvo en un rango de 12-61 mm (media 35.8±8.2 mm), mientras que en los machos fue de 14-35 mm (media, 24.8±3.4 mm). La significación estadística entre la profundidad y los índices de abundancia y biomasa se testaron mediante una ANOVA de doble vía (p 27 mm) se registraron entre junio y agosto; meses en los cuales también se observaron los máximos índices gonadosomáticos de estas hembras. En ambos sexos la relación talla-peso presentó una fuerte alometría negativa. La distribución de frecuencias de tallas mensuales señaló para las hembras seis modas por año. El reclutamiento anual se detectó entre enero y abril. La mortalidad por pesca y la tasa de explotación fueron de 0.498 año-1, 0.444 año-1 y 0.524 año-1, respectivamente para los tres períodos de muestreo. En el bahía de Antalya la actividad pesquera y los aspectos fundamentales de la biología de A. antennatus presentan una alta similitud con resultados obtenidos de otras poblaciones del Mediterráneo Central y Occidental. Las pocas diferencias que se destacan se atribuyen a las particulares condiciones oceanográficas y ambientales del área de estudio

Effects of water immersion on the recovery of upper and lower body anaerobic power following a wrestling session

The aim of this study was to examine effects of cold-water immersion after exercise on powerresponses of wrestlers. Twenty elite male wrestlers were formed by similar age, height, weight and fitness parameters. The wrestling training session included a 60-minute of vigorous exercise. It consisted of warm-up exercises, standing technical and tactical exercises that mostly allocates arm and leg muscles. Vertical jump height, ropes climb height, and delayed onset of soreness was measured before, after, 24 h and 48 hors after the wrestling training. Cold-water immersion caused decrements in power loss at each follow-up time in comparison to a thermo neutral immersion.  It can be suggested that the longer time needed for power to return to normal levels after cold treatment and assessment of varied contraction types may present a more broad demonstration of muscle function and consequential capacity for dynamic exercise following exercise-induced muscle damage

Model selection in multivariate adaptive regressions splines (MARS) using alternative information criteria

Multivariate Adaptive Regression Splines (MARS) is a useful non-parametric regression analysis method that can be used for model selection in high-dimensional data. Since MARS can identify and model complex, non-linear relationships between the dependent variable and independent variables without requiring any assumptions, it has advantage over simple linear regression techniques. Also, for simplifying the model building process and preventing overfitting, MARS can select automatically the variables to be included in the model, which is useful for datasets with many variables. While MARS is a flexible non-parametric regression method, generalized cross validation (GCV) technique is used within the MARS framework to avoid overfitting and to select the best model. GCV criterion is widely used and can be effective in many situations, however it has some criticism. These criticism are the arbitrary value of the smoothing parameter used in the algorithm of the GCV criterion and the models obtained using this criterion are high-dimensional. In this paper, it is aimed to obtain the barest model that best explains the relationship between the dependent variable and independent variables by using alternative information criteria (Akaike information criterion (AIC), Schwarz Bayesian criterion (SBC) and information complexity criterion (ICOMP(IFIM)PEU)) instead of the use of smoothing parameters in order to put an end to the criticism. To achieve this goal, a simulation study was first conducted with a data set composed of variables that do and do not contribute to the dependent variable to test the success of the information criteria. As a consequence of this simulation work, when variables (which do not contribute to the dependent variable) are not included in the regression model, it demonstrates the success of the criteria in model selection. As a real data set, the reasons for loan defaults were investigated between the years 2005–2019 by utilizing data from 18 banks operating in Türkiye. The results obtained reveal the success of ICOMP(IFIM)PEU criterion in model selection

Effect of Stirrup Spacing and Polypropylene Fiber Ratio on Behavior of Reinforced Concrete Beams

In this study, the effect of the change of stirrup ratio and polypropylene (PP) fiber ratio on the behavior of reinforced concrete beams was investigated. The variables of this study consisting of without stirrup, spacing up to 20 %, 40 % and 80 % of beam depth as stirrup spacing and 0.125 % and 0.500 % of the weight of reinforced concrete beam were used as PP fiber ratios. In the context of experimental study, 1/2 scaled 12 reinforced concrete beams were tested with 4-point bending mechanism. In the light of the obtained data, the load-displacement, stiffness and energy absorption graphs were plotted. The results were interpreted comparatively. According to the results, it is observed that the PP fiber additive significantly changed the behavior of the reinforced concrete beams, and the fiber effect decreased in proportion to the increase of the stirrup rate. It has been observed that the cracks spread more to the beam surfaces with the increase of PP fibers. In addition, the increase in the fiber ratio especially in the non-stirrup beams increases the bending capacity
