Autonomous Tractor-Trailer Stopping and Jackknifing Dynamics
… for a forward perception sensor and when jackknifing may occur. The best brake type for a tractor-trailer will be recommended as well. Finally, the best forward sensor and senor layout for an autonomous tractor-trailer is made based upon the simulation results for the stopping distance of …

Parametric, Non-Parametric And Statistical Modeling Of Stony Coral Reef Data
… of the probability distribution function of the jackknifing pseudovalues, obtained from the jackknife procedure for the Shannon-Wiener diversity index used in previous studies, using the xi nonparametric kernel density estimate method. This nonparametric procedure gives very effective estimates …

Earthquake location using a 3D velocity model : an example in Sichuan Province, China
… smaller location variability when using a jackknifing technique.

Development of active trailer steering systems for pickup truck-trailer combinations
… which lead to unstable motion modes such as jackknifing, trailer sway and rollover. Active safety systems such as Active Trailer Steering (ATS) have been widely studied to address these issues and ensure the safety of combination vehicles. Linear Quadratic Regulator (LQR) is a popular control …

Lateral stability analysis and MPC tracking control for articulated heavy vehicles
… to unstable motion modes, e.g., trailer-sway and jackknifing, causing severe accidents. However, vehicle parameters that can improve the static stability may degrade the dynamic stability. Therefore, to design controllers for improving the stability of AHVs, the trade-off between the static and …

Organization and Regulation of Proteins Required For Initiation of Cell Division In Escherichia Coli
… mostly on the side where FtsA localized, causing jackknifing of dividing cells and supporting the importance of a symmetrical FtsA ring for normal cell division. I then investigated localization patterns for FtsZ, FtsA, and ZipA in normal cells using 3D-SIM super-resolution microscopy, which …

Phylogenetic Reconstruction With Gene Order and Content Information
… to do so by resampling data sets with a jackknifing procedure adapted from sequence data analysis, but this approach has significant theoretical weakness. We have attempted to correct this weakness by incorporating a DCJ error model into a resampling method for verifying gene order based …

Experimental Evaluation of the Dynamic Performance Benefits of Roll Stability Control Systems on A-train Doubles
… during their commercial use. Outriggers and jackknifing arresting mechanisms are used to prevent vehicle damage and ensure safety during the tests. The test vehicle is equipped with multiple sensors and cameras for the necessary measurements and observations. The analog and video data are …

Roll and Yaw Stability Evaluation of Class 8 Trucks with Single and Dual Trailers in Low- and High-speed Driving Conditions
… RSC (on trailer) reduce the risk of rollover and jackknifing, and 3) RSC systems perform less effectively when the rear trailer is empty.
