Aiming at the problem that it is difficult to ensure trajectory tracking accuracy and driving stability of driverless racing car under extreme conditions high-speed turning with different road adhesion coefficients, a control strategy proposed. Firstly, coefficient estimated using extended Kalman filter algorithm. Draw phase plane diagram vehicle’s centroid sideslip angle-centroid angular veloc...

Content description has become a topic of interest for many researchers in the audiovisual field [1][2]. While manual annotation has been used for many years in different applications, the focus now is on finding automatic contentextraction and content-navigation tools. An increasing number of projects, in some of which we are actively involved, focus on the extraction of meaningful features fr...

The key to successful maneuvering complex extended object tracking (MCEOT) using range extent measurements provided by high resolution sensors lies in accurate and effective modeling of both the extension dynamics and the centroid kinematics. During object maneuvers, the extension dynamics of an object with a complex shape is highly coupled with the centroid kinematics. However, this difficult ...

b a c k g r o u n d  & aim: it is very helpful to classify and predict the clinical  category  of a sample based  on  its  gene  expression  profile.  this  study  was  conducted  to predict  tissues  of colorectal adenoma,  adenocarcinoma,  and  paired  normal  in  colon  based  on  microarray  data  using  nearest shrunken centroid method. methods   &  materials:    in  this  study,   the  co...

This study investigates acoustic characteristics of Aymara ejectives. Acoustic measurements of the Aymara ejectives were conducted in terms of the durations of the release burst, the vowel, and the intervening gap (VOT), the intensity and spectral centroid of the release burst, and H1-H2 of the initial part of the vowel. Results showed that ejectives vary with place of articulation in the durat...

3D environments provide new possibilities for musical interaction. They allow musicians to manipulate and visualize large sets of sound processes associated to 3D objects by connecting graphical parameters to sound parameters. Several of these audiovisual mappings can be combined on a single 3D object. However, this brings up the issues of the choice of these mappings and of their combinations....

Music is one of the strongest triggers of emotions. Recent studies have shown strong emotional predispositions for musical instrument timbres. They have also shown significant correlations between spectral centroid and many emotions. Our recent study on spectral centroid-equalized tones further suggested that the even/odd harmonic ratio is a salient timbral feature after attack time and brightn...

In the title compound, C(30)H(38)O(4)S(2), the centroid of the benzene ring lies on a center of inversion. The thio-phene ring is aligned at 49.8 (1)° with respect to the benzene ring. The alkyl chain adopts an extended zigzag conformation.
