Controllers design problems are multi objective optimization problems as the controller must satisfy several performance measures that are often conflicting and competing with each other. In multi-objective approach a set of solutions can be generated from which the designer can select a final solution according to his requirement and need. This paper presents the design and analysis Proportion...

This paper studies an enhanced dual-stage repetitive controller (RC) for improved robustness and tracking of periodic reference trajectories in piezo-based nanopositioning systems. The dual-stage RC system consists of a signal generator designed to provide high gain at the fundamental and all the harmonic frequencies of the reference trajectory and another that offers high gain only at the odd ...

Germline genetic mutations underlie various primary immunodeficiency (PID) diseases. Patients with rare PID diseases (like most non-PID patients and healthy individuals) carry, on average, 20,000 rare and common coding variants detected by high-throughput sequencing. It is thus a major challenge to select only a few candidate disease-causing variants for experimental testing. One of the tools c...

OBJECTIVE To study the microbial characteristics of patients with pelvic inflammatory disease (PID) and the possible impact of an intrauterine device (IUD) on the microbial environment in women presenting with PID. METHODS Case-control study, investigating 51 women with acute PID and 50 healthy women. Endocervical specimens for microbiological investigation were obtained at gynaecological exa...

This paper deals with the fractional order multi-loop controller design for a distillation column. The idea is generalization of IMC-PID-FOF method developed monovariable systems to column model which multivariable. principle based on IMC paradigm and choice appropriate control configuration minimum interactions. proposed illustrated an example taken from literature.

The plant hormone auxin is a central regulator of plant development. In Arabidopsis, the PINOID (PID) protein serine/threonine kinase is a key component in the signaling of this phytohormone. To further investigate the biological function of PID, we performed a screen for PID-interacting proteins using the yeast two-hybrid system. Here, we show that PID interacts with two calcium-binding protei...
