Motivated by recent experimental results for the step sizes of dynein motor proteins, we develope a cellular automata model for intra-cellular traffic of dynein motors incorporating special features of the hindrance-dependent step size of the individual motors. We begin by investigating the properties of the aggressive driving model (ADM), a simple cellular automata-based model of vehicular tra...

Bacteriophage phi29 utilizes a motor to translocate genomic DNA into a preformed procapsid. The motor contains six pRNAs, an enzyme and one 12-subunit connector with a central channel for DNA transportation. A 20-residue peptide containing a His-tag was fused to the N-terminus of the connector protein gp10. This fusion neither interfered with procapsid assembly nor affected the morphology of th...

objectives: the aim of this study was to determine the effect of perceptual-motor training on motor skills of normal preschool children (aged 4-6 years) in esfahan city. methods: this was a quasi-experimental study with intervention and control groups. each group included 30 normal preschool children aged 4 to 6 years. they were selected randomly children of intervention group one empowering ch...

The effect of residential neighborhood characteristics on a child's risk of serious motor vehicle traffic occupant injuries was evaluated in New York State, USA, for the years 1993-2003, with particular focus on the effect of neighborhood walkability. Risk increased significantly (p < 0.0001) with decreasing street connectivity and as more workers commuted more than 30 min using means other tha...

Linear induction motors are under development for a variety of demanding applications including high speed ground transportation and specific industrial applications. These applications require machines that can produce large forces, operate at high speeds, and can be controlled precisely to meet performance requirements. The design and implementation of these systems require fast and accurate ...

In the absence of visual information, our brain is able to recognize the actions of others by representing their sounds as a motor event. Previous studies have provided evidence for a somatotopic activation of the listener's motor cortex during perception of the sound of highly familiar motor acts. The present experiments studied (a) how the motor system is activated by action-related sounds th...

Intracellular molecular motor-driven transport is essential for such diverse processes as mitosis, neuronal function, and mitochondrial transport. Whereas there have been in vitro studies of how motors function at the single-molecule level, and in vivo studies of the structure of filamentary networks, studies of how the motors effectively use the networks for transportation have been lacking. W...

In Saudi Arabia the motor vehicle is the main means of transportation. Between 1971 and 1997; 564,762 people died or were injured in road traffic accidents, a figure equivalent to 3.5% of the total population in Saudi Arabia. During this period 66,914 people have died on the roads in Saudi Arabia due to road accidents, amounting to one person killed and four injured every hour. Over 65% of acci...

This paper implements a new technology for identifying dust particles in industrial motors and to increase motor efficiency. Present modern industries are highly sophisticated industries. The use of advanced technologies, including satellite communications, automation, smart sensors, and robotics is widespread. Computers and microprocessors are responsible for making big machines reliable and e...

The paper deals with the synthesis of some neuro-fuzzy speed and current controllers for a vector control based structure associated with an asynchronous motor and an inverter. Many operating conditions for the system are taken into account, like speed reference profile (including some special ones for a smooth motion in a transportation system), quadrants, load torque etc. The final goal is to...
