In this work we obtain a new description of the vertical motion of the car including the active suspension. It consists of 4 completely decoupled subsystems. The first 3 ones are of order 4 each and they are analogous to standard quarter car suspension models. The 4th subsystem is of order 2 and it introduces a new abstract variable denoted by γ. One of the novelties of this modeling result is ...

Patients with rheumatoid arthritis have been treated alternately with aurothioglucose and aurothiomalate. In the earlier part of the study an oily suspension of aurothioglucose and an aqueous solution of aurothiomalate were used, but later an aqueous solution of aurothioglucose was alternated with the oily suspension and an oily suspension of aurothiomalate with the aqueous solution. Skin erupt...

Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...

This paper presents the design of a robust controller for a vehicle air suspension system using Quantitative Feedback Theory (QFT). This study is primarily focused on control of linearized active air suspension system. For the purpose of simplicity, the dynamics of the air suspension system is modeled using a simple 2-DOF quarter car model. Uncertain dynamic system with different working condit...

ABSTRACT: Active control is indispensable to electromagnetic suspension system in order to stabilize the open-loop system. For simplicity, linear control strategy is widely utilized in practical maglev systems. However, electromagnetic suspension system is inherently highly nonlinear, which makes linear control strategies sometimes fail in experiments. To conquer the nonlinearity of the suspens...

The influence of polymeric dispersants containing different functional groups on TiO2 pigment particle suspension was investigated at pH 6.0 and 9.5, using rheology and particle size data. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers modified with carboxylate and/or hydroxyl groups. The pigment suspension was strongly affected by both p...
