This paper deals with kinematics and dynamics of the human shoulder in order to obtain the workspace related to the reachability of the wrist and applications to determine load for the wheelchair. The model contains six revolute degrees of freedom (D.O.F), two in costoclavicular and three in the shoulder joint and one in the elbow joint, while a six D.O.F model was developed according to given ...

introduction one of the factors that affect the climate of arid and semi-arid areas is dust storm. numerical models are new methods for evaluation of dust storms which can also be used for forecasting dust storms. weather patterns that lead to dust outbreaks can be simulated using computer models that support a wide range of simulations related to the long-range transport, dispersion, and depos...

in this paper, trajectory generation for the 4 dof arm of surena iii humanoid robot with the purpose of optimizing energy and avoiding a moving obstacle is presented. for this purpose, first, kinematic equations for a seven dof manipulator are derived. then, using the lagrange method, an explicit dynamics model for the arm is developed. in the next step, in order to generate the desired traject...

The time-optimal trajectory for an airplane from some starting point to some final point is studied by many authors. Here, we consider the extension of robot planer motion of Dubins model in three dimensional spaces. In this model, the system has independent bounded control over both the altitude velocity and the turning rate of airplane movement in a non-obstacle space. Here, in this paper a g...

In this paper, we present a novel technique for predicting and visualizing users' future navigations. Here, user navigation is considered as the sequence of URL's visited by the user. We have used distance-based specific trajectory clustering to partition users and integrated with Markov model for predicting users' future navigation. For testing the proposed technique, we developed a tool calle...

Human speech production is often described as an optimisation process, which tends to maximise the effectiveness of the communication process minimising the effort involved in the production. The aim of this paper is to investigate this highly complex problem with two dimensionally reduced spaces corresponding to different computational models. Since the highdimensional parameter space which us...

This paper describes a semantic connection between the symbolic trajectory evaluation model-checking algorithm and relational verification in higher-order logic. We prove a theorem that translates correctness results from trajectory evaluation over a four-valued lattice into a shallow embedding of temporal operators over Boolean streams. This translation connects the specialized world of trajec...

“Segmental hidden Markov models” (SHMMs) are intended to overcome important speech-modelling limitations of the conventional-HMM approach by representing sequences (or segments) of features and incorporating the concept of trajectories to describe how features change over time. A novel feature of the approach presented in this paper is that extra-segmental variability between different examples...
