in this paper, the unified power flow controller (upfc) is enhanced with a chaotic particle swarm optimization (cpso) damping controller in order to mitigate the low frequency oscillations (lfo) in a single machine infinite bus (smib) power system. the designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

this study proposes a combination of a fuzzy sliding mode controller (fsmc) with integral-proportion-derivative switching surface based superconducting magnetic energy storage (smes) and pid tuned by a multi-objective optimization algorithm to solve the load frequency control in power systems. the goal of design is to improve the dynamic response of power systems after load demand changes. in t...

To the Editor: The incidence of unilateral spatial neglect (USN) has been described in up to 30%270% after an injury to the right hemisphere. USN is one of the strongest predictors of poor functional recovery, which can lead to more prolonged hospitalization and disrupt rehabilitation and recovery of functional disabilities after stroke, thus limiting independence. However, USN is not usually a...

Visual neglect (VN) is a common consequence of right hemisphere (RH) stroke. The aims of this study were to explore the presence of VN after RH stroke in the patients with (T+) or without (T-) thrombolytic treatment, and to determine whether thrombolysis is a predictor of VN. The study group consisted of 77 RH infarct patients. VN was evaluated with six conventional subtests of the Behavioural ...

Unilateral visuo-spatial neglect is a neuropsychological syndrome commonly resulting from right hemisphere stroke at the temporo-parietal junction of the infero-posterior parietal cortex. Neglect is characterized by reduced awareness of stimuli presented on patients' contralesional side of space. Inspired by evidence of increased spatial exploration of patients' left side achieved during keyboa...

Abstract This paper focuses on virtual commissioning of a robotic manufacturing system, its theoretical background, and an analysis importance in the design automated systems. Virtual allows PLC control program to be tested debugged created digital model machine, called twin machine. Just this solution can simulate optimize system itself without need have real hardware (PLC, automation elements...

the aim of this article is to investigate the structural relationship between social influence, motivation and facilitating conditions with the use behaviour of teleworking technology, considering the moderating effect of behavioural intention to utilize teleworking. the research is done according to descriptive method with correlational type. statistical population is public organizations and ...

anti-lock braking system (abs) is a nonlinear and time varying system including uncertainty, so it cannot be controlled by classic methods. intelligent methods such as fuzzy controller are used in this area extensively; however traditional fuzzy controller using simple type-1 fuzzy sets may not be robust enough to overcome uncertainties. for this reason an interval type-2 fuzzy controller is de...

Dynamical systems offer intriguing possibilities as a substrate for the generation of behaviour due to their rich behavioural complexity. However this complexity together with the largely covert relation between the parameters and the behaviour of the agent is also the main hindrance in the goal oriented design of a behaviour system. The paper presents a general approach to the self-regulation ...
