Effect of Circuit Training on the Sprint-Agility and Anaerobic Endurance
No full textTasxkin, H. Effect of circuit training on the sprint-agility and anaerobic endurance. J Strength Cond Res 23(6): 1803-1810, 2009-The purpose of this study was to determine the effect of circuit training directed toward motion and action velocity over the sprint-agility and anaerobic endurance. A total of 32 healthy male physical education students with a mean age of 23.92 +/- 1.51 years were randomly allocated into a circuit training group (CTG; n = 16) and control group (CG; n = 16). A circuit training consisting of 8 stations was applied to the subjects 3 days a week for 10 weeks. Circuit training program was executed with 75% of maximal motion numbers in each station. The FIFA Medical Assessment and Research Centre (F-MARC) test battery, which was designed by FIFA, was used for measuring sprint-agility and anaerobic endurance. Pre- and posttraining testing of participants included assessments of sprint-agility and anaerobic endurance. Following training, there was a significant (p < 0.05) difference in sprint-agility between pre- and posttesting for the CTG (pretest = 14.76 +/- 0.48 seconds, posttest = 14.47 +/- 0.43 seconds). Also, there was a significant (p < 0.05) difference in anaerobic endurance between pre-and posttesting for the CG (pretest = 31.53 +/- 0.48 seconds, posttest = 30.73 +/- 0.50 seconds). In conclusion, circuit training, which is designed to be performed 3 days a week during 10 weeks of training, improves sprint-agility and anaerobic endurance
Editorial board member and prolific author status positively shorten publication time
No full textPublication speed is one of the important aspects of scholarly communication today since a good deal of research performance evaluation systems are based on published articles. This study aims to reveal the factors affecting the publication speed of journals. In this context, six library and information science (LIS) journals, ASLIB Journal of Information Management, Journal of Documentation, Journal of Informetrics, Journal of the Association for Information Science and Technology, Online Information Review, and Scientometrics are analysed in terms of their publication speed. Results show that being an editorial board member or prolific author for journals significantly shortens the duration of publication. Moreover, when there is at least one editorial board member or prolific author in the author group, the duration of the publication is shorter than the articles from the unknown authors. However, the fact that no significant difference is determined between single- and double-blind peer review and the duration of publication process gives an idea about the scientific levels of articles written by editorial board members or prolific authors. In this regard, our approach is to examine other factors affecting the publication speed by conducting multi-dimensional analysis in future studies
Turkish Adaptation of the Eco-Spirituality Scale: Its Association with Emotional Connectedness to Nature, Positive Future Expectation, and Mental Well-being
No full textThis research includes two separate studies focusing on eco-spirituality in Turkish adults (N1=413, N2=399). Data were collected through convenience sampling, allowing us to reach 812 participants aged 18-78. In Study 1 [325 (78.7%) females and 88 (21.3%) males], Confirmatory factor analysis, Item Response Theory, validity and reliability analyses were conducted in the adaptation study of the Eco-spirituality Scale. In Study 2 [294 (73.7%) female and 105 (26.3%) male], the mediating role of positive future expectation in the relationship between eco-spirituality and mental well-being was tested. Research findings suggest that the Turkish version of the Eco-spirituality Scale is a valid and reliable measurement tool and can be used to measure eco-spirituality in adults. In addition, the results demonstrate that positive future expectation mediates the relationship between eco-spirituality and mental well-being. These findings confirm the strong psychometric properties of the scale, supporting its use in future research on eco-spirituality. © Copyright 2025 by Author(s
TMVP-Friendly Primes for Efficient Elliptic Curve Cryptography
No full textThe need for faster and practical cryptography is a research topic for decades. In case of elliptic curve cryptography, which was proposed by Koblitz and Miller in 1985 as a more efficient alternative to RSA, the applications in real life started after 2000s. Today, most of the popular applications and protocols like Whatsapp, Signal, iOS, Android, TLS, SSH, Bitcoin etc. make use of Elliptic curve cryptography. One of the important factor for high performance elliptic curve cryptography is the finite field multiplication. In this paper, we first describe how to choose proper prime fields that makes use of Topelitz-matrices to get faster field multiplication, then we give parameter choice details to select prime fields that supports Toeplitz-matrix vector product operations. Then, we introduce the safe curve selection rationale and discuss about security. We propose new curves, discuss implementation and benchmark results and conclude our work
Full-Waveform Inversion for Breast Ultrasound
No full textBreast cancer is the most common type of cancer for women and in developed countries it forms one of their largest threats. Many studies have shown that early detection by screening is important for achieving a successful treatment and reducing the mortality rate. Nowadaysmammography is the gold standard for breast cancer screening. However, mammography has several drawbacks including the use of ionizing radiation, a painful procedure, and poor performance with dense breasts. Magnetic resonance imaging (MRI) could form an alternative as it has some powerful features. However, the high examination and equipment costs as well as the use of contrast agents limits its applicability. Another potential alternative for breast cancer screening is ultrasound. Ultrasound has the advantage over mammography orMRI that it is safe, cheap and patient-friendly. With ultrasound, a tumor can be detected since healthy breast tissues and cancerous tissues have different acoustic properties. All these features make ultrasound a promising candidate as a screening modality for breast cancer. Hand-held ultrasound scans are frequently used for breast imaging in hospitals. With these scanners reflectivity images are generated. These images typically show the boundaries between different tissues. Even when these exams are conducted by trained radiologists operator-dependency occurs. To eliminate this, automated full-breast ultrasound scanners have been developed where the transducer slides over the breast. However, as the imaging principle remains the same, only reflectivity images are generated. To avoid significant breast deformation as well as to scan the breast from as many sides as possible water-bath scanning systems have been developed. These systems have the additional advantage that both reflection and transmission measurements are obtained. This mixture of different measurement types make it feasible to obtain better images by employing advanced processing techniques. One promising imaging method is full-waveform inversion (FWI). FWI aims to match a modeled wavefield to a measured wavefield by adjusting the acoustic medium parameters. A minimization problem is constructed and solved to this aim. As a result, images showing quantitative information about the different tissues are obtained. This quantitative information aids to the characterization and identification of the different tissues. However, there are some challenges when applying FWI. One of the biggest challenges is its computational complexity. By the inclusion of wave phenomena such as diffraction, refraction, scattering and dispersion - needed to explain the measured data in great detail - the computational complexity of FWI has become significantly larger than conventional - mainly ray based - imaging methods. In this work, we investigate the applicability of contrast source inversion (CSI) as an FWI method for breast ultrasound. To this end, we first introduce our full-waveform forward modeling method which is based on solving an integral equation. With a synthetic example,we investigate howeach mediumparameter (compressibility, density, and attenuation) affects the scattered pressure field. The obtained results show that attenuation, in contrast to compressibility and density, has only little effect on the wavefield for frequencies below 1MHz. From that we conclude, that for these frequencies only attenuation can be neglected in our inversion. We also compare the results from our full-waveform modeling method with results obtained after commonly made approximations such as Born, ray-based and paraxial approximations. We observe from the presented numerical results that with each approximation important phenomena normally present in the full-wave data are absent. For this reason, we recommend to use a full-wave modeling method to compute synthetic measurement data.ImPhys/Medical Imagin
Modelling Porosity Permeability of Ceramic Tiles using Fuzzy Taguchi Method
Get PDFTaguchi experiment design in quality development studies, is an approach to engineering that supports research and development, product design and product development activities by enabling fewer trials of experiments to determine the best combinations of inputs that affect the outcome. In this study, the factors affecting the porosity were studied in a firm that produces ceramic tile. There were 6 factors considered to be important in total and 2 levels in each factor. L8 orthogonal array were used during the experiment design, which proposes 8 experiment types with different factor levels. The results of the experiments were analyzed so that important factors were determined. Significance of factors were tested by ANOVA and 4 of them were found to be significant. These factors were fuzzified by assessing the factors using linguistic expressions and then triangular fuzzy numbers. A model with 4 inputs and 1 output was built and 34 rules were generated for this model. The developed model was shown to be a useful approach in modeling the porosity permeability of ceramic tiles
