In this case you can earn continent- foreign country - or home country points and they will be accepted as World - or foreign country points. Your cat can win the following awards when your cat compete with other ones.
The judges nominate for race or color of the cat. The nominated cats come on stage as a group- the judges decide together who the winner is. Dominating cat races are divided into by their haircolor.
So a nomination is justizgesetz nrw to the cats justizgesetz nrw the best hair. Rare cat races are not divided. They compete in one big group and there is only one winner.
Analysing what is available at Justizgesetz nrw that can be used for instrumentation and control, two things stand out: Important process knowledge is wasted. Therefore, the scope of the thesis is to set the scene by introducing the state of the art in the fields of WWTP operation, process monitoring and control and justizgesetz nrw subsequently develop and justizgesetz nrw three novel methods and to assess their potential for practical implementation.
Those are, on the one hand, the automated calibration of a simulation model for the Rospe WWTP that provides a basis for the development and evaluation of the subsequent methods, and on the other hand, the development of soft sensors for the WWTP inflow which estimate the crucial process variables COD and NH 4 -N, and the estimation of WWTP operating states using Self-Organising Maps SOM that are used to determine the optimal control parameters for each state.

These collectively, provide the basis for achieving comprehensive WWTP optimization 19 Introduction 1. The major contributions are as follows: The simulation model represents the real WWTP with its main hydraulic and biological characteristics and thus ensures that the developed ICA strategies can be successfully implemented in practice and are of high relevance to practitioners.
The proposed automated calibration method is a novel and sophisticated solution to this problem. By optimizing the justizgesetz nrw calibration with respect to two separate fitness functions rather than a single combined fitness function i.
Furthermore, model calibration is much faster and available to a broader user base due to its easy applicability. Unfortunately, online instrumentation for these parameters is expensive and maintenance intensive, which is why most WWTP do justizgesetz nrw have them in the inflow.

The development of a virtual measurement system, so-called soft sensors is a solution. Based on available process data from standard instrumentation, machine learning methods, both regression and classification methods, were justizgesetz nrw and trained justizgesetz nrw estimate COD and NH 4 -N in the WWTP inflow.
In order to evaluate the performance of the soft sensors an extensive measurement campaign was conducted at the Rospe WWTP.
Furthermore, a toolbox for data pre-processing and sensitivity analysis using a stepwise backward elimination algorithm was developed to improve the machine learning results. Based on a performance function that compares the simulated concentrations measured in the biological justizgesetz nrw with the actual values over a defined - 4 - 20 Introduction estimation horizon, estimating the inflow concentrations can be formulated as an optimisation problem.
As this optimization is high dimensional and justizgesetz nrw Kriging surrogate models of the performance function are used to speed up the estimation process.

An evaluation of the methodology for the Rospe WWTP model highlights that it is severely impacted by variable retention times as well as blending of different wastewater and recirculation streams in a WWTP, with the result that it has limited utility.
In justizgesetz nrw, there is mostly one control strategy for a control loop that is not adapted to varying process conditions but more a compromise as the different process stated are unknown.
Using Self-Organising Maps SOM process data is analysed and justizgesetz nrw information mapped onto justizgesetz nrw two-dimensional feature space, in order to visualise the different operating regimes of a WWTP.
This information can then be used for the development of optimal controllers for each operating regime.
In order to identify these set justizgesetz nrw a Genetic Algorithm GA was used. Results justizgesetz nrw that a significant improvement in plant operation can be achieved.
Chapter 2 provides the necessary background to the field of wastewater treatment using activated sludge with a focus on describing the whole process chain and the related challenges.
