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 psychone-uroimmunology that stress influences the immune system response. From the various models of emotions related to stress available in literature, the(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 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)
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)
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)
The paper proposes a path-planning approach that generates a global optimal path according to a criterion, which has to guarantee " minimum path length and no collisions with obstacles ". The optimization procedures reported in the literature use gradient descent techniques and suffer the local minima problem. The main contribution of the paper consists in(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)
