In the present work, the influences of temperature, solvent concentration and ultrasonic irradiation time were numerically analyzed on viscosity reduction of residue fuel oil (RFO). Ultrasonic irradiation was applied at power of 280 W and low frequency of 24 kHz. The main feature of this research is prediction and optimization of the kinematic viscosity data. The measured results of eighty-four...

Background. Kinanthropometric and Kinematic variable are important in the understanding of performance in various sports. These variables have not been explored among Tennis players in Nigeria. Objectives. An exploration to establish a regression model for kinanthropometric and kinematic variables in relation to ball velocity of Nigerian Female Tennis Players. Methods. Data were collected thr...

This paper discusses the dynamics computation of closed kinematic chains, especially those found in motions of human gures. A number of e cient dynamics computation algorithms have been established in robotics for open kinematic chains and particular types of closed kinematic chains, such as parallel ve-bar link mechanisms and the Stewart platform. The dynamics computation of closed kinematic c...

−− A generic kinematic control, which is directly applicable to any type of wheeled mobile robot, is proposed in this work. Firstly, it is presented the kinematic models of the four common types of wheels (fixed, centered orientable, castor and Swedish) a classification of wheeled mobile robots. Afterwards, it is proposed a kinematic control scheme with three nested loops: dynamic, kinematic an...

We have been interested in Automatic Guided Vehicles (AGV) for several years. In this paper, we synthesize controllers for AGV applications using monocular vision. In particular, we are interested in road following and direction change tasks, and in analyzing the influence of extrinsic camera parameter perturbations on vehicle behavior. We use the bicycle as the kinematic vehicle model, and we ...

Kinematic chain is a combination of links connected by different kinematic pairs (joints). The study of the nature of connection among various links of a kinematic chain is known as structural analysis or topological analysis. In this paper to help the analysis, several methods of representation of the kinematic structure are presented. The study includes the functional schematic representation...

Within a human motion analysis system, body parts are modeled by simple virtual 3D rigid objects. Its position and orientation parameters a t frame t+ 1 are estimated based on the parameters a t frame t and the image intensity variation from frame t to t + 1, under kinematic constraints. An optimization procedure calculates the 3D parameters that make a goal function that measures the intensity...
