A Video-Based Analysis of Rhythmic Accuracy and Maintenance in Junior Tennis Players

2017-01-01
This study mainly focused on the video-based analysis of two parameters of rhythmic ability: rhythmic accuracy (RA) and rhythmic maintenance (RM). The effects of tempo on these parameters were also investigated. The participants were junior competitive tennis players (n= 41, age= 13.46 1.64 years). The video-based analysis system that relies entirely on the features extracted automatically from the audiovisual data was used to determine the RA and RM performances of the participants for the tempos of 44 and 50 bpm. The results revealed that participants significantly performed better RA and RM scores in fast tempo test. In addition, results also indicated that participants had significantly higher scores on accuracy task in both tempos. In conclusion, the study attempted to determine the rhythmic ability via a video based system. Using the proposed system, rhythmic ability analysis can be applied to a wide range of participants in a very short time and further analysis on the collected data can easily be conducted

An Investigation of the relationship between working memory capacity and verbal and mathematical achievement
Leblebicioğlu, Ayşegül; Cedden, Gülay; Department of English Language Teaching (2012)
This study aims to find out the relationship between Working Memory Capacity and Verbal and Mathematical Achievement. The participants were 60 students at Hacettepe University School of Foreign Languages Department of Basic English. For measuring working memory capacity, one simple (Digit Span Task) and one complex (Reading Span Task) were used. Verbal achievement of the participants was measured both in their native language (Turkish) and their foreign language (English). For measuring their native languag...
Modeling of plosive to vowel transitions
Beköz, Alican; Demirekler, Mübeccel; Department of Electrical and Electronics Engineering (2007)
This thesis presents a study concerning stop consonant to vowel transitions which are modeled making use of acoustic tube model. Characteristics of the stop consonant to vowel transitions are tried to be obtained first. Therefore several transitions including fricative to vowel transitions are examined based on spectral and time related properties. In addition to these studies, x-ray snapshots, lip videos and also experiments including subjects are used to intensify the characterization, from the production...
A Study On Pre-Service Teachers’ Spatial Visualization Ability and Spatial Anxiety
Erkek, Özlem; Isıksal Bostan, Mine; Çakıroğlu, Erdinç (2017-01-01)
This study aims to investigate the pre-service teachers’ spatial visualization ability and spatial anxiety levels with respect to their gender and undergraduate programs. Data were collected from 1007 third and fourth year undergraduate pre-service teachers enrolled in elementary mathematics, science, and early childhood education programs from four universities in Ankara, Turkey. Spatial Visualization Test and the Spatial Anxiety Scale were used as data collection instruments. The results revealed a statis...
Evaluation of the site amplification factors estimated by equivalent linear site response analysis using time series and random vibration theory based approaches
Stanko, Davor; Gülerce, Zeynep; Markusic, Snjeana; Salic, Radmila (2019-02-01)
The objective of this study is to estimate and compare the site amplification factors (AFs) using two different one dimensional (1-D) equivalent-linear (EQL) site response analysis approaches: the time series (TS) approach and the random vibration theory (RVT) based method. For this purpose, random soil profiles combined with different soil types, EQL soil properties, and unit weights are tested at several input ground motion levels. Analysis results showed that the AFs estimated by the TS-approach are syst...
Effect of solid state power amplifier nonlinearity on various phase shift keying modulation schemes
Dudak, Celal; Koç, Arzu; Department of Electrical and Electronics Engineering (2005)
This study concentrates on the performance evaluation of a specific modulation scheme under nonlinear operation. This modulation scheme is the phase shift keying (PSK) modulation, exemplified by the special cases of BPSK, QPSK, OQPSK, p/4-QPSK. The specific nonlinear block is chosen to be the solid state power amplifier (SSPA) structure whose simulation model is the Rapp model. Varying transmitter filter characteristic and one of the power amplifier parameters constitute the main methodology of simulations....
