    This paper describes a new bubble segmentation algorithm based on shape from shading for in-situ microscopy. An in-situ microscope is an instrument to capture and analyze intensity images of cells inside of a bioreactor with minimal operator intervention and without the risk of culture contamination. For bubble segmentation, the closed bubble boundaries are first extracted by thresholding a depth ... View full abstract»

    In this paper, an algorithm is introduced for segmenting the foreground regions present in a human insulin crystal intensity image captured by an in-situ microscope inside of a bioreactor. The segmentation is carried out by classifying all image pixels into pixels belonging to the foreground regions and pixels belonging to the background region. For classification, the local intensity variance at ... View full abstract»

    The new general methodology for the analog system optimization was elaborated by means of the optimum control theory formulation in order to improve the characteristics of the system design process. A special control vector is defined to redistribute the compute expensive between a network analysis and a parametric optimization. This approach generalizes the design process and generates a set of t... View full abstract»

    The problem of analog system design for a minimal computer time has been formulated as the functional minimization problem of the control theory. The design process in this case is formulated as the controllable dynamic system. The conception of the Lyapunov function of dynamic controllable system is used to analyze the principal characteristics of the design process. The different forms of the Ly... View full abstract»

    Photodynamic therapy is a well know treatment based on the interaction of light with a photosensitizer drug and oxygen. It has been used for the treatment of certain diseases, especially cancer. One of the major problems in the implementation of the therapy is the use of lasers as light sources which increases the cost of the therapy. This is why we propose the development of photodynamic therapy ... View full abstract»

    In this paper, we describe a system that can carry out visual simultaneous localization and mapping (VSLAM) in structured indoor environments; this system uses a small-sized low-cost commercial humanoid robot which uses a camera mounted on a pan-and-tilt device (it was designed and built by us) as his head. Almost all of the VSLAM approaches use points 2D like features of the robot's environment f... View full abstract»

    Compressive sampling (CS)is a emerging technique with many applications on signal processing field. It states that it is possible to reconstruct a signal from a number of samples below the well-known Nyquist limit. The success of the reconstruction depends on the capability of a frontend transform to represent the signal in a sparse way. In this paper, we propose the use of the discrete cosine tra...

    Building system software is hard. It is necessary to have a methodology to achieve good systems. Presently, there are a few methods for developing multi-agent-based systems. Taking experience of solutions that worked well in the past is the main purpose of the design patterns, which were found in designing object-oriented software. In this work, we present three design patterns that could be used ... View full abstract»
