This paper presents the estimation of substrate and biomass concentrations inside a Chemostat used for waste-water treatment. These concentrations represent the state variables of the process model. Most research in this field used only deterministic models, not accounting for uncertainties and noises on the states and on the output. Hence, the estimation of these concentrations may not be sufficiently accurate. For a more realistic description, we used here a stochastic formulation. Unlike the other research works, we used a stochastic differential equations (SDE) model which provides a better representation of the system in his natural processing scale. This model also includes the aleatory effects in the process which had been discarded in the other works. We then deal with the state estimation problem using an Extended Kalman filter, which proceeds with a linearization of the model around a deterministic trajectory. The classical prediction and update steps of the filter are then carried-out and led to good results. Notice that the system in study has some interesting properties such as discrete-time observations, high noise intensities and slow-time evolution. Results are presented, discussed and compared with the related state-of-the-art researches.

Aim: The aim of the study was to explore objectively the visual analyzer (VA) function by pattern visual evoked potentials (PVEPs) in patients with diabetes mellitus (DM) in different stages of diabetic retinopathy (DR) and to compare the results with controls and between the different groups. Material and methods: This is a prospective observation study with 3-year duration (20142017). A group of 185 people was studied. Patients with DM were 138. They were divided into two main groups patients without DR and patients with DR. The first group consisted of two subgroups – patients with newly-diagnosed DM (33 people) and patients with DM duration longer than 1 year (mean DM duration 6.8 ± 4.2 years) (36 people). The second main group consists of patients with DR, divided into two subgroups – patients with initial DR (34 people) and patients with advanced DR (35 people). Controls for the EF studies were 47 healthy individuals. PVEPs were performed. The main variables that were considered in the results analysis were the latency and amplitude, reflecting the configuration of the wave forms. Results: PVEPs results were affected even in patients without DR. The changes in PVEPs values became more distinct in patients with initial DR group as а number of components with significant difference as well as a degree of significant difference, to reach their maximum number and significance manifestation peak in patients with advanced DR, the most affected by DM group. Conclusion: PVEPs studies could be used as an objective methods for registration of early changes in the VA function as a DM complication. Also, to monitor the changes in dynamics as they are non-invasive, harmless, fast, inexpensive and repeatable.

Very topical nowadays is the modeling and simulation of conflict situations. The aim is their peaceful prevention and conflict resolution. Different mathematical approaches are used. One of them is the application of multi-agent systems. The multiagent system consists of software agents, which are autonomous subjects working together. In our application the agents represents police officers and civilians in case of protest. In this work we propose application of intuitionistic fuzzy sets for representation of the movement and interaction of the agents. The intuitionistic fuzzy sets are extension of the fuzzy sets including level of uncertainty. Thus the model becomes more realistic. The conflict situation can cause disturbances and casualties. Crowd simulation is very difficult and important research topic.

The purpose of the cluster analysis is to find groups of objects with similar characteristics. Different methods are already developed. In the current research work a CLIQUE: Clustering in quest algorithm is investigated. The presented method combines subspace grid-based and density-based techniques to determine clusters of objects. Generalized net of cluster analysis using CLIQUE: Clustering in quest algorithm is constructed. The presented Generalized net can be used for description and monitoring the parallel processes in the cluster analysis.

Hypertension means increase in blood pressure. There are different drugs which are available both as single dose and as combination therapy for treatment and management of hypertension. Our target is Angiotensin Converting Enzyme (ACE) inhibitors for better therapy or improved therapy of the hypertension patient. ACE in complex with inhibitor lisinopril, zinc cation and chloride ions (anions) have a similar structure to angiotensin I and bind to the active site of the ACE protein. The literature suggested that there are different classes of ACE inhibitors and describes their interaction with currently available drugs. We have also compiled the data on the proper management of hypertension with another relevant disease like diabetes. The number of available PDB three dimensional structure of ACE protein having different organism (74); Homo sapiens (49), Drosophila melanogaster (22), Severe acute respiratory (5), Paguma larvata (5), Bacillus thermoproteolyticus (3), Severe acute respiratory (3), Gloydius blomhoffii (2), Other (3). Our target is a well-known protein with high resolution in a human structure that is crystal structure of the Angiotensin1 converting enzyme N-domain in complex with amyloid-beta 35-42 (PDB ID-5AMB) of recently submitted (2015) with high resolution (1.55 Å). The characteristic features of ACE having a zinc binding metallopeptidase consist of two domain of N and C terminal (different binding pattern). We have designed a better ligand interaction with this protein.
