Some studies have already addressed the effects of occupational organic solvent exposure on the visually evoked potentials (VEPs). Visual system is an important target for Sulphur Mustard (SM) toxicity. A number of Iranian victims of Sulphur Mustard (SM) agent were apprehensive about the delay effect of SM on their vision and a possible delay effect of SM on their visual cortex. This investigat...

This paper deals with active tracking of 3D moving targets. The performance and robustness in visual control of motion depend on the vision algorithms and the control structure where dynamical aspects can not be neglected. Visual tracking is presented as a regulation control problem. Both system architecture and controller design are discussed. The performance of visually guided systems is subs...

Abstract: A new decomposition method is presented to handle optimal control design for two-degree of freedom time delay control systems. In this approach exact relationships between the actuator, process and design parameters furthermore the Nyquist stability margin are developed for a first order time delay process. The ultimate robustness limit of any control can be explicitly calculated usin...

To increase precision and reliability of automatic control systems, we have to take into account of random factors affecting the control system. Thus, operational matrix technique is used for statistical analysis of first order plus time delay system with uniform random parameter. Examples with deterministic and stochastic disturbance are considered to demonstrate the validity of the method. Co...

Many essential appliances like air conditioners and refrigerators which run in our offices and homes draw a heavy starting current. When the main power resumes or turned ‘ON’ suddenly, all the loads are switched ‘ON’ at a time and a very heavy initial current is drawn from mains. The current drawn is so high that other equipments are affected. The valuable home appliances can be ruined for such...

This research extends a static threshold based control strategy used to control headway variation to a dynamic threshold based control strategy. In the static strategy, buses are controlled by setting a threshold value that holds buses at a control point for a certain amount of time before allowing the bus to continue along the route. The threshold remains constant each time the bus stops at th...

The random time delay in a networked control system can usually deteriorate the control performance and stability of the networked control system. In order to solve this problem, this paper puts forward a networked control system random time-delay compensation method based on time-delay prediction and improved implicit generalized predictive control (GPC). The least squares support vector machi...

The emergence of DTN as an option for sustaining communication in environments with high delay/frequent disruption have rendered existing access control mechanisms inappropriate hence the need for a new concept in DTN access control. This is primarily due to contradicting assumptions like low delay and constant connectivity on which the existing mechanisms are built. This paper discusses the se...

In this paper, the stability of time-delayed DC motor speed control systems is analyzed. The measurement devices and communication links used by networked control systems, cause a significant amount of time delays. The stability boundary of the system in terms of the time delay is theoretically determined and an expression is obtained to compute the delay margin in terms of system parameters. T...
