Control generation precise implementation

Temperature. The process temperature of an evaporative crystallizer may be controlled by the absolute pressure in the vessel. Direct flow control of steam to an ejector, while economizing on steam utilization, is subject to pressure fluctuations due to disturbances in the steam supply pressure. Applying cascaded flow control would decrease the response time of the control loop. Flow control of a bleed gas or exhausted gas into the suction of the vacuum source is the most responsive and precise control option. Critically damped tuning of the pressure control loop should be implemented to prevent rapid temperature changes and high supersaturation generation from fast swings in pressure. [Pg.220]

There are several limitations that need to be addressed. The proposed approach allows for automated development of strucmre of simulation models while information models driven development of control mechanisms is supported to a limited extent. Improving implementation of control mechanisms is a direction of further research. The approach can only be efficient if high reusability is achieved. Therefore, a precise specification of model transformation and generation mechanisms is required. [Pg.193]

The Computer. Modern computer-controlled NMR spectrometers allow the implementation of practically any sophisticated pulse sequences such as INEPT (10) or INADEQUATE (11). Very precise clock timing together with the ability to pulse simultaneously the emitter and the decoupler with their own relative rf phases are then a must for the computer. This task is appertaining to the computer pulse generator which is now a standard item on commercial systems ... [Pg.10]

More precisely, the kernel starts by initializing itself and then the different partitions, which are to be executed in a predefined static order. The MPIC generates an interruption each time a dedicated counter reaches a specific value. The kernel uses the MPIC to implement the temporal partitioning between applications an interrupt is generated each time a time slot allocated for a particular partition ends up. The dedicated counter is then set to zero, the context of the current partition is backed-up and the context of the next partition to be executed is restored. Regarding the memory isolation, the MMU is used for spatial partitioning it controls the memory accesses in such a way that a partition cannot read or write application data used in the context of another partition. [Pg.148]

The huge variety of defined nanostmctures and materials that can be fabricated via controlled radical polymerization techniques will probably find applications in a wide field of different research directions. The possibility of combining several building units in one device will enable materials scientists to implement multiple levels of stimuli-responsiveness for the construction of smart materials. Research in biomedicine can be expected to benefit from the ability to generate defined nanopattemed surfaces that can play a central role in biophysical investigations. Also, the potential to create precisely defined confined environments could lead to nanocontainers as delivery vehicles, theranostic agents, or artificial enzymes. [Pg.217]
