Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...

The present study aimed to analyze the interaction and main effects of deliberate practice experience and small-sided game format (3 vs. 3 and 6 vs. 6 plus goalkeepers) on the offensive performance of young soccer players. Twenty-eight U-15 male players were divided into 2 groups according to their deliberate practice experience in soccer (i.e., years of experience in federation soccer): Non-Ex...

This study assessed the construct validities and the relationships between Optimism [21], Hope [27], Self-Efficacy [18], and Locus of Control [12]. The validities and relationships between these scales were examined not only because they are to some degree rival constructs but also because there is an outstanding theoretical question in the literature of whether each of these variables is a sta...

â â â  â â  abstract: â  china and asean have been maintaining a relationship both cooperative and competitive in the textile trade. due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. the customs data (classified by the hs code) from year 2006-2009 is employed to research the impact of the cris...

We consider the asymptotic variance of the departure counting processD(t) of the GI/G/1 queue;D(t) denotes the number of departures up to time t. We focus on the case that the system load % equals 1, and prove that the asymptotic variance rate satisfies lim t→∞ VarD(t) t = λ ( 1− 2 π )( ca + c 2 s ) , where λ is the arrival rate and ca, cs are squared coefficients of variation of the inter-arri...

The aims of the present study were firstly to examine the reproducibility of outdoor flat and uphill cycling time trials (TT), and secondly to assess the relationship between peak power output (Wpeak) obtained in the laboratory and outdoor cycling performance in moderately trained cyclists. Eight competitive male cyclists first performed a progressive cycle ergometer test in the laboratory to d...

The purpose of this quantitative study was to investigate the instructional effects of various animation strategies. Three treatment groups involved include static graphic, animation used as an attention-gaining strategy, and animation used as an attention-gaining and elaboration strategy. Participants were 115 college student volunteers. Two-way multiple analysis of variance (MANOVA) was used ...

Postprandial changes in plasma total cholesterol (TC) are minimal and there is essentially no difference between fasting vs random TC concentrations, as reflected in the small diurnal coefficient of variation (CV) for TC of 2.5%. Similarly, a cholesterol-rich meal within the last 24 hours lacked an impact on plasma TC. Thus, random specimens are acceptable in blood cholesterol screening. The in...

We have searched for a light pseudoscaler particle “X(214)” which is suggested by HyperCP experiment in the K0 L → π0π0X(X → μ+μ−) decay process using the E391a detector at KEK. In our analysis, signal event “X(214)” has not observed with the 3.58 × 109 K0 L decays, and we set an upper limit for the branching fraction of K0 L → π0π0X(X → μ+μ−) to be 1.6 × 10−6 at the 90% confidence level. Also ...
