Background. The iterative sure independence screening (ISIS) is a popular method in selecting important variables while maintaining most of the informative variables relevant to the outcome in high throughput data. However, it not only is computationally intensive but also may cause high false discovery rate (FDR). We propose to use the FDR as a screening method to reduce the high dimension to ...

A variable structure slip control strategy is developed for grasping objects by a robot end-effector. A hybrid controller comprised of a fuzzy controller and a PI controller is designed to perform the strategy. When a grasped object is slipped by an external force as a disturbance, the applied fingertip force is rapidly increased to stop sliding and then decreased to a reliable limit to hold th...

the goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. the effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. this is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...

This article offers a new perspective on sociological theory, based on psychological insights from Perceptual Control Theory. After describing this cybernetic model of goal-directed behavior and reviewing its empirical support, I present results from computer simulations applying the model to the social interactions of elementary control agents. My key finding is that agents controlling their o...

The fluid flow control systems can be classified depending on the type of pressure source, on the pipe system structure and on the control element. Depending on the pressure source type, the flow control systems can be equipped with centrifugal pumps or volumetric pumps. Concerning the pipe structure, the flow control systems can be used within the hydraulic systems with branches or without bra...

The following work introduces a replication system build around CRDTs with a new convergent replicated datatype for a distributed version control system. It retains the order of write operations at the tradeoff of reduced availability with after-the-fact conflict resolution. The combined system allows to develop applications with distributed state in a similar fashion to native applications wit...

The article is devoted to a motion control problem for a differentially driven mobile robot in the task of trajectory tracking in the presence of skid-slip effects. The kinematic control concept presented in the paper is the Vector Field Orientation (VFO) feedback approach with a nonlinear feed-forward skid-slip influence compensation scheme. The VFO control law guarantees asymptotic convergenc...

In this paper, experimental study of robust control for robot manipulator actuated by pneumatic artificial muscles was realized. The experimented controller belonged to the class of variable structure systems which is called nonsingular terminal sliding mode (NTSM). The control approach is based on the time delay estimation method. First, the nonsingular terminal sliding mode control approach w...
