TRIFECTA's 2016--2018+ Malibu recalibration is complimented by a fully developed 8-speed (2016) and 9-speed (2017+) automatic transmission calibration to support the increased power delivery profile and to offer dramatically improved driving characteristics from everyday driving maneuvers. The complete powertrain calibration also includes ESC (Stabilitrak) program enhancements.

One approach which is increasingly being used to study team tactics is the team centroid method (Folgado et al. 2014; Frencken et al. 2011, 2012; Yue et al. 2008). Here the behavior of the team centroid, the geometric center of the positions of all players from a team, is used to analyze the behavior of the whole team. Results from this line of research indicate a strong coupling between team centroids during game play (Frencken et al. 2011), changes of inter-centroid distances due to pitch size variations (Duarte et al. 2012a, b; Frencken et al. 2013), and key game events like goal shots are accompanied by increased inter-team coupling variability (Frencken et al. 2012). More recently, investigation of centroid behavior has been further extended by calculating the Approximate Entropy (ApEn) (Pincus and Goldberger 1994), a non-linear time-series measurement techniques, to quantify the regularity in time-series data (Aguiar et al. 2015; Goncalves et al. 2014; Sampaio and Macas 2012). Results using ApEn analysis suggest increased centroid behavior regularity after tactical training in novice players (Duarte et al. 2012a, b; Sampaio and Macas 2012). Goncalves et al. (2014) investigated the coordination during on 11-a-side game between and within the defenders, mid-fielders, and attacker subgroups using ApEn. The results showed that players movements were more regular with respect to the centroid of their respective groups compared to the other groups. Sampaio et al. (2014) further showed that during an inferiority situation during a 5-a-side small sided game the regularity of the distance to the team centroid increased. Goncalves et al. (2016) investigated the influence of numerical imbalances between attacking and defending team in small sided games in professional and amateur players. Player numbers varied between 4 versus 3, 4 versus 5, and 4 versus 7. The results showed that in experts an increase in the number of opponents increased the regularity in team behavior with respect to the opponents. Although the application of ApEn is becoming more prominent, it still remains to be shown what this measure really represents as the regularity behavior of team centroids in itself represent a highly abstract description of team behavior. Nevertheless, team centroid measures increasingly are being used to capture team behavior and many interesting applications have been reported in the literature in recent years. 350c69d7ab
