Social insects are simple organisms capable (separately) of very limited activities with a view to intelligent behaviour. Each of them performs a local task unaware both of the behaviour of the others and of the implementation of the global task. However in groups, they possess some degree of intelligence, that allows them to perform extremely complex(More)
The paper proposes a methodology of using artificial immune networks (aiNets) for a classification problem oriented to cancer outcome prediction on the basis of gene expression profiling. The aiNet is a discrete (iterative) computational model that adopts clonal selection and affinity maturation principles from biological immune systems. The treatment(More)
Developing mobile robots able to move autonomously and staying operational in unexplored environments is one of the most important aims of intelligent robotics research. Navigation (here in the sense: collision-free goal following behaviour) depends on the amount of a priori available information. It could be assumed that this information comes in the(More)
This article investigates the effects of emotional intervention on artificial immune networks used for navigation of autonomous agents (simulated autonomous mobile robots). It is known from psychoneuroimmunology that stress influences the immune system response. From the various models of emotions related to stress available in literature, the computational(More)
The paper presents a series of experiments in a simulated environment where two autonomous mobile robots gather randomly distributed objects and cluster them into one pile. The coordination of the robots' movements is achieved through stigmergy (an indirect form of communication through the environment). In order to avoid the drawback of the random moves,(More)
The paper treats fuzzy-logic-based modeling the influences of temperature and substrate concentration on the output current of biosensor for measurement of dopamine. Quantitative determination of dopamine in urine and plasma is very important for curing diseases like ganglioneuroma, schizophrenia, manic-depressive psychosis, stress, burn-out syndrome, etc.(More)
An approach using potential functions applied to formation control (including aggregation, collision-free goal following behavior, and trajectory tracking one) is proposed. The formation control is considered as a special form of agent aggregation, where the final aggregated form has to constitute a particular previously determined geometrical configuration(More)
ABSTACT: The aim of the article is to investigate the optical properties of Bulgarian honey in regard to the potential of honey discrimination on the base of its botanical origin. Samples from three types of honey (acacia, linden, and honeydew) are measured by a fluorescence spectrometer recording emission from 350 to 800 nm with excitation at 370, 395 and(More)
The aim the investigation reported is to determine the potential of determining the botanical origin of honey by a combination of middle infrared spectroscopy, colorimetry and chemometric analysis. Forty-three samples from three types of honey (acacia, linden, and honeydew) are subjected to Fourier transform mid-infrared (Mid-FTIR) spectroscopy.(More)
Diffuse Large B-cell Lymphoma (DLBCL) is curable in about 40% of patients. The treatment (chemotherapy or stem cell support) of DLBCL depends on the distinction of the significant subtypes of this kind of cancer and influences on the cured/fatal outcome of the disease. Molecular analyses of clinical heterogeneity in DLBCL focus on individual genes, some of(More)
