financial scientists have always been eager to distinguish between whether the price series could be random walk (unit root) or mean reverting processes.by a random walk we mean that accruing shocks to the system have permanent impacts and prices do not revert to their previous trend path, in addition, regarding to random walk processes the price series volatility could increase with out any li...

There are a variety of factors affecting steering performance on off-road vehicles, including vehicle dynamics and soil stiffness. It is essential to understand the steering dynamics for designing a reasonable electrohydraulic (E/H) steering control system for wheel-type tractor. A computer-controlled E/H steering simulator, consisting of a steering actuator and a steering load simulator, is an...

Concatenative synthesis is a sample-based approach to sound creation used frequently in speech synthesis and, increasingly, in musical contexts. Unit selection, a key component, is the process by which sounds are chosen from the corpus of samples. Hidden Markov Models are often chosen for this task, but one common criticism is its singular path output which is considered too restrictive when va...

This paper addresses the path following problem of a wheeled mobile robot with rhombic like kinematics (two drivable and steerable wheels) operating in cluttered environments. Four new path following controllers are developed to steer the kinematic model of a rhombic like vehicle along a desired path: three are based on feedback laws derived at a kinematic level with geometrical inspiration; wh...

Original scientific paper By introducing a novel permanent magnetic bi-stable electromagnetic clutch unit (PMBECU) in the driveline of directly-driven electric vehicle, a flexible connection between motor and hub is realized with characteristic of separated starting process of drive motor and wheel load. Firstly, the working principle and power supply scheme for the PMBECU is discussed. Then th...

Train pneumatic brakes are part of a train safety system, and are thus critical components. This paper illustrates how modeling can be applied to efficiently design such system, from requirement definition to HIL testing. The valves modeling is discussed along with the system level model. Moreover, in order to study the wheel-slide protection device, a model of the wheel-rail interface has been...

We have previously shown that cocaine enhances gene regulation in the sensorimotor striatum associated with procedural learning in a running-wheel paradigm. Here we assessed whether cocaine produces enduring modifications of learning-related changes in striatal neuron activity, using single-unit recordings in anesthetized rats 1 day after the wheel training. Spontaneous and cortically evoked sp...

This project work presents the sensor fusion of Global Positioning System (GPS), Inertial Measurement Unit (IMU) and Odometry data from wheel encoders which is used to estimate localization of mobile robot. GPS, IMU, Wheel encoders are interfaced with MBED. Filters are used to remove erroneous noise from the data obtained from sensors. Low pass IIR filter is used for Differential Global Positio...
