Turku PET Centre, Turku University Hospital, Turku, Finland This study was performed to evaluate the feasibility of preclinical imaging in a clinical PET/MR system. Preliminary sequences were evaluated for establishing preclinical protocols for rat brain and rabbit knee. Rats were placed in a stereotactic holder, allowing a 30 minute scan time before re-administration of anesthesia. In-house de...

In Model Reference Adaptive Control (MRAC) the modeling uncertainty is often assumed to be parameterized with time-invariant unknown ideal parameters. The convergence of parameters of the adaptive element to these ideal parameters is beneficial, as it guarantees exponential stability, and makes an online learned model of the system available. Most MRAC methods however, require Persistent Excita...

This paper presents the design and performance analysis of Differential Evolution (DE) algorithm based Proportional-Integral-Derivative (PID) controller for temperature control Continuous Stirred Tank Reactor (CSTR) plant in chemical industries. The proposed work deals about order to improve CSTR. In this, process is controlled by controlling liquid through manipulation coolant flow rate with h...

This paper presents a new design of adaptive fuzzy variable structure control to solve the traditional problem of model reference adaptive control (MRAC) for a class of single-input, single-output minimum-phase uncertain nonlinear systems via backstepping. Instead of taking the tedious coordinate transformation and yielding a "hard" high-gain controller, we introduce smooth B-spline-type member...

Using multiple interacting drugs to control both the mean arterial pressure (MAP) and cardiac output (CO) of patients with different sensitivity to drugs is a challenging task which this paper attempts to address. A multivariable model reference adaptive control (MRAC) algorithm is developed using a two-input, two-output patient model. The control objective is to maintain the homodynamic variab...

This paper describes the development and implementation of a dynamic positioning system for Remotely Operated underwater Vehicles (ROVs) which is based on a mechanical Passive Arm (PA) for position measurement. The system, named DPSROV, is suited for tasks which require precise positioning within a limited range around a working site. The DPSROV was conng-ured aiming at easy installation in mos...

In this paper, the decentralized control of generalized systems is considered via a frequency domain approach. Firstly, based on the design of generalized decentralized observer-based controllers, a state-space representation of the decentralized Bezout identity is developed for generalized decentralized control systems with two control channels. Secondly, all the stabilizing decentralized cont...
