Since the emergence of PID controllers, control system engineers are in pursuit of more and more sophisticated versions of these controllers to achieve better performance, particularly in situations where providing a control action to even a minimal degree of satisfaction is a problem. This work is an attempt to contribute in this field. Variations in the values of weight, the friction coeffici...

BACKGROUND Pelvic inflammatory disease (PID) is a leading cause of both tubal factor infertility and ectopic pregnancy. Chlamydia trachomatis is an important risk factor for PID, but the proportion of PID cases caused by C. trachomatis is unclear. Estimates of this are required to evaluate control measures. METHODS We consider 5 separate methods of estimating age-group-specific population exc...

PIDs and cancer: an evolving story ---------------------------------------------------------------------------------------------------------------Luigi D. Notarangelo HARVARD MEDICAL SCHOOL Analysis of overall and site-specific cancer risk in patients with primary immunodeficiency diseases (PIDs) may shed light on the role played by the immune system in controlling malignancies. The association...

In this paper, we propose a PID parameter tuning of particle swarm optimization for multiobjective optimization characteristics of two regional power system PID controller design. By defining a comprehensive consideration of system output overshoot, rise time and the fitness function term steadystate error indicators, such as the ITAE, and in accordance with the performance requirements of the ...

Primary immunodeficiencies (PID) are inherited disorders of immune system function [1,2] characterised by absent or low response to infectious agents and a high prevalence of autoimmune manifestations and lymphoproliferative diseases. More than 120 PID in which a molecular defect causes the disease have been identified. The IUIS/WHO Experts Committee published a classification of all PID known ...

Criteria based on disturbance rejection and system robustness are proposed to assess the performance of PID controllers. A simple robustness measure is defined and the integral gains of the PID controllers are shown to be a good measure for disturbance rejection. An analysis of some well-known PID tuning formulas reveals that the robustness measure should lie between 3 and 5 to have a good comp...

The Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) features two conceptions of Narcissistic Personality Disorder (NPD), one based on the retained DSM-IV's categorical diagnosis and the other based on a model that blends impairments in personality functioning with a specific trait profile intended to recapture DSM-IV NPD. Nevertheless, the broader literature contains...
